Description

A self-adjusting hydraulic lifting system for engineering

Technical Field

The invention belongs to the field of hydraulic equipment, and in particular relates to an engineering hydraulic lifting system with self-adjusting points.

Background technique

In the field of engineering construction, prefabricated buildings are becoming increasingly popular; the on-site assembly of various prefabricated parts has largely replaced the on-site casting of components, which can greatly reduce the construction cost of engineering projects and improve construction efficiency. In the prefabricated process, large-scale hoisting machinery and hydraulic lifting machinery are required. When lifting components in existing construction projects, it is usually necessary to pre-install the hydraulic system. The pre-installed hydraulic equipment will not be able to move during the actual operation, and the number of hydraulic equipment cannot be temporarily increased. This results in the inability to flexibly adjust the support points and loads of the hydraulic lifting system according to the needs of the engineering site during the engineering operation process, which in turn limits the application of hydraulic equipment in prefabricated construction projects.

Summary of the invention

In order to solve the problem that the existing hydraulic equipment cannot be flexibly adjusted according to the needs of the engineering site during use, the present invention provides a hydraulic lifting system for engineering with self-adjusting points.

The present invention is implemented by the following technical solutions:

A self-adjusting hydraulic lifting system for engineering use, comprising a plurality of hydraulic cylinders, a hydraulic control system, and an adjusting component. The hydraulic control system is connected to the hydraulic cylinders and is used to control the extension and retraction of each hydraulic cylinder; the adjusting component is used to adjust the spatial layout of each hydraulic cylinder installed thereon. The adjusting component comprises a base, a plurality of slides, a plurality of adapter plates, and a controller.

The base includes a chassis, a turntable and an annular guide rail. The turntable is located at the center of the chassis; the annular guide rail is concentrically arranged on the outer periphery of the turntable. The turntable can rotate relative to the chassis and is also provided with a vertical upward lever.

Each slide body includes a first slider and a linear actuator. The first slider is clamped on the annular guide rail and can move along the annular guide rail. The linear actuator includes a linear guide rail and a second slider. The linear guide rail in the linear actuator is horizontally mounted on the first slider and extends radially along the annular guide rail. The second slider can reciprocate on the linear guide rail along the radial direction of the annular guide rail.

The adapter plate is a Z-shaped bending plate; each adapter plate is arranged along the radial direction of the annular guide rail, the lower step surface of the adapter plate is fixed on the second slider, and the higher step surface extends outward. The end of the lower step surface of the adapter plate is provided with a notch that matches the lever; the higher step surface is provided with a through hole for installing the hydraulic cylinder.

The controller is electrically connected to the hydraulic control system, the turntable and the linear actuator. The controller is used to automatically generate a state adjustment strategy for each hydraulic cylinder according to the difference between the current hydraulic cylinder point layout and the received target point layout. Then, the hydraulic control system is used to drive the designated hydraulic cylinders to extend and retract to adjust the number of hydraulic cylinders involved in the hydraulic lifting system; coordinate the linear actuator and the turntable to adjust the angle of the hydraulic cylinders involved in the operation relative to the reference direction; and adjust the distance between the hydraulic cylinders involved in the operation and the center of the chassis through the linear actuator.

As a further improvement of the present invention, a plurality of typical point layout diagrams and a switching rule table of any two point layout diagrams are preset in the controller; thereby supporting the generation of a state adjustment strategy of the hydraulic cylinder by table lookup.

As a further improvement of the present invention, the slides and hydraulic cylinders in the adjustment assembly correspond one to one, and the number of slides and hydraulic cylinders pre-installed on the annular guide rail is equal to the maximum number of support points required for the current engineering operation.

As a further improvement of the present invention, the strategy of the controller to adjust the azimuth angle of any hydraulic cylinder relative to the reference direction is as follows:

First, the hydraulic cylinder is controlled to retract and exit the operation; then the turntable is controlled to rotate so that the lever thereon corresponds to the position of the adapter plate on the corresponding sliding body; then the second slider in the linear actuator is controlled to slide toward the side close to the turntable so that the notch on the adapter plate engages with the lever; then the turntable is controlled to rotate to drive the combination of the sliding body and the hydraulic cylinder to reach a preset position; finally, the second slider in the linear actuator is controlled to slide toward the side away from the turntable so that the lever is disengaged from the notch.

As a further improvement of the present invention, when the controller adjusts the point layout of the hydraulic cylinder, the angle adjustment is performed first and then the distance adjustment is performed. When the distance between any hydraulic cylinder and the center of the chassis increases after the layout adjustment, the second slider in the linear actuator is driven to move away from the turntable, and vice versa. Move to the side close to the turntable.

As a further improvement of the present invention, the hydraulic cylinder adopts a double-headed cylinder; the double-headed cylinder has a cylinder body and two telescopic rods located at both ends of the cylinder body; the two telescopic rods move synchronously and telescopically along both sides of the cylinder body.

As a further improvement of the present invention, the linear actuator adopts a sliding screw, a cylinder, an electric cylinder, an electric slide or any other driving mechanism capable of realizing linear reciprocating motion.

As a further improvement of the present invention, a plurality of electric mortise locks are evenly distributed on the base near the annular guide rail, and a lock hole is provided on the first slider. The electric mortise lock has a retractable lock tongue, thereby locking the first slider when it reaches a preset position.

As a further improvement of the present invention, the turntable is driven by a servo motor or a stepper motor.

As a further improvement of the present invention, a plurality of position sensors are arranged on the base; the position sensors are evenly distributed along an annular area concentric with the annular guide rail, and are used to detect the spatial position of each sliding body. Each position sensor is electrically connected to the controller.

The technical solution provided by the present invention has the following beneficial effects:

The self-adjusting point engineering hydraulic lifting system provided by the present invention installs the hydraulic cylinder in a newly designed adjustment component. The adjustment component can use a turntable and a linear actuator to arbitrarily adjust the spatial position of the hydraulic cylinder on the plane where the chassis is located. After using the hydraulic lifting system provided by the present invention, engineering technicians can flexibly adjust the number and position of the hydraulic cylinders used according to the needs of the site during the operation to meet the construction requirements of the prefabricated project.

The present invention combines the hardware structure of the hydraulic lifting system with the design, and also optimizes the equipment operation strategy during the adjustment of the number and position of the hydraulic cylinders, thereby realizing the state adjustment strategy of the layout of different points automatically generated by the controller, and realizing the automatic control of the operation state of various electronic control components, and realizing the automatic adjustment and remote control of the spatial layout of the hydraulic cylinders. This is very practical in most small working spaces or pre-buried spaces, and can overcome the disadvantage that traditional equipment cannot perform process adjustment.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

Example 1

This embodiment provides a self-adjusting hydraulic lifting system for engineering use, which includes a plurality of hydraulic cylinders 4, a hydraulic control system 40, and an adjustment component. The hydraulic control system 40 is connected to the hydraulic cylinders 4 and is used to control the extension and retraction of each hydraulic cylinder 4; the adjustment component is used to adjust the spatial layout of each hydraulic cylinder 4 installed thereon. As shown in FIG1 , the adjustment component includes a base 1, a plurality of slides 2, a plurality of adapter plates 3, and a controller 100.

As shown in FIG2 , the base 1 includes a chassis 11, a turntable 12 and an annular guide rail 13. The chassis 11 in this embodiment is a circular chassis 11, and the turntable 12 is located at the center of the chassis 11; the turntable 12 can rotate relative to the chassis 11 and is also provided with a vertically upward lever 121. The annular guide rail 13 in this embodiment is a guide rail with an "I"-shaped cross section. The entire annular guide rail 13 is formed by splicing multiple arc-shaped guide rails and is connected to the chassis 11 through fasteners. The spliced annular guide rail 13 can facilitate the disassembly of the first slider 21 installed thereon, thereby realizing the flexible adjustment of the number of installed slides 2 and hydraulic cylinders 4 according to the operation content. Specifically, the annular guide rail 13 is concentrically arranged on the outer periphery of the turntable 12. In this embodiment, the turntable 12 is driven by a servo motor or a stepper motor. The servo motor or the stepper motor can accurately control the rotation of the turntable 12 according to the received instructions.

As shown in FIG3 , each slide 2 of the adjustment assembly is composed of a first slider 21 and a linear actuator 22. The first slider 21 is clamped on the annular guide rail 13 and can move along the annular guide rail 13. It should be noted that the annular motion mechanism formed by the first slider 21 and the annular guide rail 13 in this embodiment is not powered, and the first slider 21 cannot move on the annular guide rail 13 spontaneously. The solution of this embodiment is to drive the first slider 21 to move on the annular guide rail 13 through the linear actuator 22 and the turntable 12. The detailed working principle will be introduced later.

In the scheme of this embodiment, the linear actuator 22 can adopt a sliding screw, a cylinder, an electric cylinder, an electric slide or any other driving mechanism that can realize linear reciprocating motion. For example, the linear actuator 22 shown in the figure adopts an electric slide, which is composed of a linear guide 222 and a second slider 221 clamped thereon. The linear guide 222 in the linear actuator 22 is horizontally installed on the first slider 21 and extends radially along the annular guide 13. Different from the annular motion mechanism formed by the first slider 21 and the annular guide 13, the linear actuator formed by the second slider 221 and the linear guide 222 in this embodiment can move spontaneously, and the second slider 221 can reciprocate radially along the annular guide 13 on the linear guide 222 according to the received instructions.

As shown in FIG4 , the adapter plate 3 is a Z-shaped bending plate; each adapter plate 3 is arranged along the radial direction of the annular guide rail 13, the lower step surface of the adapter plate 3 is fixed on the second slider 221, and the higher step surface extends outward. The end of the lower step surface of the adapter plate 3 is provided with a notch 31 that matches the lever 121; the higher step surface is provided with a through hole 32 for installing the hydraulic cylinder 4. In the actual application process of the engineering hydraulic lifting system with self-adjusting points provided in this embodiment, the number of slides 2 installed on the base 1 corresponds to the number of hydraulic cylinders 4, and each slide 2 is fixedly connected to a hydraulic cylinder 4 through an adapter plate 3. During installation, the hydraulic cylinder 4 is inserted into the through hole 32 at the end of the adapter plate 3 and is fixedly connected to the adapter plate 3 through fasteners. The installed hydraulic cylinder 4 remains perpendicular to the plane where the chassis 11 is located.

In particular, the hydraulic cylinder 4 in this embodiment adopts a double-headed cylinder; the double-headed cylinder has a cylinder body and two telescopic rods at both ends of the cylinder body; the two telescopic rods move synchronously along the two sides of the cylinder body. When a jacking operation is required, the cylinder body in the double-headed cylinder is extended synchronously along the two sides to complete the jacking. When the jacking height needs to be reduced, the two telescopic rods are retracted synchronously, thereby reducing the distance between the upper and lower ends of the hydraulic cylinder 4.

The engineering hydraulic lifting system with self-adjusting points provided in this embodiment uses a controller 100 as a control center, and various electronic control components are coordinated to achieve flexible adjustment of parameters such as support points and overall load during lifting or jacking operations. Specifically, as shown in FIG5 , the controller 100 is electrically connected to the hydraulic control system 40 , the turntable 12 , and the linear actuator 22 .

The method of using the engineering hydraulic lifting system with self-adjusting points provided in this embodiment is as follows:

When installing the equipment, the technicians need to determine the maximum number of hydraulic cylinders 4 involved in the work according to the maximum load required in the actual operation process and the point layout diagram of all hydraulic cylinders 4 that need to be adjusted. Then, the corresponding number of slide bodies 2 and adapter plates 3 are pre-installed on the annular guide rail 13 in the base 1. Next, the corresponding number of hydraulic cylinders 4 are respectively installed in the adapter plates 3 on each slide body 2, and finally, each hydraulic cylinder 4 is connected to the hydraulic control system 40 through a hydraulic pipeline; the assembly of the engineering hydraulic lifting system with self-adjusting points is completed.

After assembly, the self-adjusting engineering hydraulic lifting system will be embedded in the working space of the actual engineering application scenario. During use, the hydraulic control system 40 pumps hydraulic oil to each hydraulic cylinder 4 through the hydraulic pipeline according to the instruction, thereby completing the lifting operation. When it is necessary to adjust the number and spatial position of the hydraulic cylinders 4 participating in the work in the self-adjusting engineering hydraulic lifting system, the controller 100 first automatically generates a state adjustment strategy for each hydraulic cylinder 4 based on the difference between the current point layout of the hydraulic cylinder 4 and the received target point layout. Then, the hydraulic control system 40 is used to drive the designated hydraulic cylinders 4 to extend and retract to adjust the number of hydraulic cylinders 4 participating in the operation in the hydraulic lifting system; then, the linear actuator 22 and the turntable 12 are coordinated to adjust the angle of the hydraulic cylinders 4 participating in the operation relative to the reference direction; finally, the linear actuator 22 is used to adjust the distance between the hydraulic cylinders 4 participating in the operation and the center of the chassis 11.

In the engineering hydraulic lifting system with self-adjusting points in this embodiment, the point layout diagram is a data reflecting the spatial position of the hydraulic cylinder 4 involved in the operation process. For example, Figure 6 contains two different point layout diagrams. In the upper half of Figure 6, the four hydraulic cylinders A1~D1 are distributed in a square, and in the lower half of Figure 6, the five hydraulic cylinders A2~E2 are distributed in a pentagon. Taking the two typical point layout diagrams in Figure 6 as an example, assuming that the upper half of Figure 6 is the distribution of the hydraulic cylinder 4 in the current state, and the lower half is the distribution of the hydraulic cylinder 4 in the target state, the process of the controller 100 in this embodiment generating a state adjustment strategy according to the two point layout diagrams is as follows:

(1) Generate a polygon based on the layout of N points;

(2) Generate the inscribed circle corresponding to the polygon;

(3) Establish an angular coordinate system with the center of the inscribed circle as the origin;

(4) Generate the angular coordinates (β, r) corresponding to the positions of each hydraulic cylinder 4 in the established angular coordinate system;

(5) Based on the angular coordinates of each point before and after the adjustment, use any path planning algorithm to generate a point rearrangement path that satisfies the non-interference requirement and minimizes the total movement angle of each point.

Taking Figure 6 as an example, it is necessary to explain the following features: In the scheme of this embodiment, all hydraulic cylinders 4 have actually been pre-installed into the hydraulic lifting system during the equipment assembly process, but in the point layout state in the upper part of Figure 6, E1 is a "virtual point" that does not participate in the work, while in the point layout state after adjustment in the lower half of Figure 6, the hydraulic cylinder 4 corresponding to point E1 also starts to participate in the work. The final state adjustment strategy is: A1→A2, B1→B2, E1→C2, C1→D2, D1→E2,

The state adjustment strategy provided in this embodiment follows the strategy of first adjusting the azimuth angle β of each point and then adjusting the radius r of each point. This is because in the adjustment component designed by the present invention, after the angle adjustment is completed, no matter what kind of adjustment is made to the radius of each point, no interference will occur.

Figure 6 of this embodiment shows a typical point layout adjustment idea, that is: any polygon can roughly generate a circumscribed circle based on most of the points therein, and then establish an angular coordinate system in combination with the circumscribed circle, and then obtain the angular coordinates of each point, and generate an adjustment strategy based on the angular coordinates of each point before and after the adjustment. Although this strategy may cause difficulties in generating adjustment strategies when the point layout is a complex polygonal layout, in actual application, the point layout of the hydraulic cylinder 4 is usually not too complicated. For example, in most scenarios, the points of the hydraulic cylinder 4 only need to be adjusted between the spatial layouts that conform to the positive N deformation. Based on this situation, the controller 100 of this embodiment also presets a variety of typical point layout diagrams, as well as a switching rule table for any two point layout diagrams; thereby supporting the generation of a state adjustment strategy for the hydraulic cylinder 4 by table lookup.

After clarifying the adjustment strategy of the point layout, the strategy of the controller 100 to adjust the number of hydraulic cylinders 4 is relatively simple. When the number of hydraulic cylinders 4 decreases, it is only necessary to determine which hydraulic cylinder 4 needs to stop working according to the front and rear point layout diagrams, and then adjust it to the "non-interference" position, and control the hydraulic cylinder 4 to retract to a state where it does not contact the lifting object. When the number of hydraulic cylinders 4 increases, the hydraulic cylinder 4 in an idle state is moved to the corresponding point of the next operation according to the front and rear point layout diagrams, and then the hydraulic cylinder is controlled to extend to a state where it contacts the lifting object.

In this embodiment, the strategy of the controller 100 to adjust the azimuth angle of any hydraulic cylinder 4 relative to the reference direction is as follows:

First, the controller 100 needs to issue a command to the hydraulic control system 40 to drive the hydraulic cylinder 4 adjusted in this round to exit the operation and retract to the shortest state without contacting the lifting object. In this embodiment, the hydraulic cylinder 4 is controlled to retract to the shortest state to avoid contact with the lifting object during movement, and on the other hand, to avoid contact with other components of the equipment itself (such as the chassis 11) to cause interference. In addition, it should be emphasized that when the hydraulic cylinder 4 is adjusted in point during the lifting operation in this embodiment, only one of the hydraulic cylinders 4 is allowed to be adjusted at a time, thereby avoiding that when too many hydraulic cylinders 4 exit the operation, the remaining hydraulic cylinders 4 will be damaged due to overload.

After the hydraulic cylinder 4 is retracted, a command is issued to the turntable 12 to control the turntable 12 to rotate so that the lever 121 on the turntable 12 corresponds to the position of the adapter plate 3 on the corresponding slide 2. The equipment coordinate system of the hydraulic lifting system of this embodiment adopts angular coordinates, and the azimuth angles of the positions of the turntable 12 and the slide 2 are known. It only needs to adjust the azimuth angles of the two to be consistent so that the notch 31 on the adapter plate 3 is opposite to the lever 121 on the turntable 12.

Next, as shown in FIG7 , the second slider 221 in the linear actuator 22 is controlled to slide toward the side close to the turntable 12, so that the notch 31 on the adapter plate 3 is engaged with the lever 121. In this embodiment, the linear actuator 22 has limited the stroke of the second slider 221221 during the product design and component installation stages, and ensures that when the second slider 221221 slides inward to the end of the stroke, the notch 31 on the adapter plate 3 can be exactly connected and engaged with the lever 121 on the turntable 12.

As shown in FIG8 , when the lever 121 is locked with the notch 31, the hydraulic cylinder 4, the adapter plate 3, the linear actuator 22, the first slider 21 and the turntable 12 essentially form a combination. At this time, the controller 100 issues a command to the turntable 12 to control the combination to rotate, and the combination of the slider 2 and the hydraulic cylinder 4 can be driven to reach a preset position. That is, the azimuth angle of the hydraulic cylinder 4 is adjusted.

Finally, after the azimuth angle adjustment of the hydraulic cylinder 4 is completed, the controller 100 sends a command to the linear actuator 22 to control the second slider 221 to slide away from the turntable 12 so that the lever 121 is disengaged from the notch 31 .

In the solution of this embodiment, after the orientation adjustment of each hydraulic cylinder 4 is completed, the distance of each hydraulic cylinder 4 relative to the origin (i.e., the center of the turntable 12) can be adjusted. During the adjustment process, when the distance between any hydraulic cylinder and the center of the chassis 11 increases after the layout adjustment, the second slider 221 in the linear actuator 22 is driven to move away from the turntable 12, and vice versa. Move to the side close to the turntable 12.

Combined with the above content, it can be known that the second slider 221 and the linear guide 222 for radially executing the motion in the adjustment assembly belong to an electric slide, in which a self-locking structure is provided between the second slider 221 and the linear guide 222. The annular guide 13 and the first slider 2121 on the chassis 11 are unpowered devices. In order to ensure that the turntable 12 can slide the first slider 21 in the assembly state more smoothly, a self-locking mechanism is usually not provided between the first slider 21 and the annular guide 13. In order to prevent the first slider 21 from sliding on the annular guide 13 after the position adjustment is completed, in a more optimized solution of this embodiment, a plurality of electric latches 5 are evenly distributed near the annular guide 13 on the base 1, and a lock hole is provided on the first slider 21. The electric latch 5 has a retractable lock tongue. When the first slider 21 is moved to a preset position, the electric latch 5 extends the lock tongue and inserts it into the lock hole on the first slider 21 to lock its position. When it is necessary to further adjust the position of the hydraulic cylinder 4, the controller 100 sends a command to the battery lock to control the lock tongue to retract and complete the unlocking.

In a more optimized solution of this embodiment, a plurality of position sensors 6 are further provided on the base 1; the position sensors 6 are evenly distributed along an annular area concentric with the annular guide rail 13. These position sensors 6 can be used to detect the actual spatial position of each slide 2 during the state adjustment process. Each position sensor 6 is electrically connected to the controller 100, and the detection signal of the position sensor 6 is sent to the controller 100 as feedback information. In addition to the position sensor 6, in a further optimized solution of this embodiment, a micro camera can also be installed around the turntable 12 of the chassis 11 to obtain the status of each component and the lifting object inside the working space in real time.

In the scheme of this embodiment, the controller 100 in the engineering hydraulic lifting system with self-adjusting points is essentially a computer device for realizing data processing and instruction generation, which includes a memory, a processor, and a computer program stored in the memory and can be run on the processor.

It can also be an intelligent terminal capable of executing a program, such as a tablet computer, a laptop computer, a desktop computer, a rack server, a blade server, a tower server or a cabinet server (including an independent server, or a server cluster composed of multiple servers), etc.

In this embodiment, the memory (i.e., a readable storage medium) includes a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., an SD or DX memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, etc. In some embodiments, the memory can be an internal storage unit of a computer device, such as a hard disk or a memory of the computer device.

In other embodiments, the memory may also be an external storage device of the computer device, such as a plug-in hard disk, a smart media card (SMC), a secure digital (SD) card, a flash card, etc., equipped on the computer device. Of course, the memory may also include both the internal storage unit of the computer device and its external storage device. In this embodiment, the memory is generally used to store the operating system and various application software installed on the computer device. In addition, the memory may also be used to temporarily store various data that have been output or are to be output.

The processor may be a central processing unit (CPU), a graphics processing unit (GPU), a controller 100, a microcontroller 100, a microprocessor, or other data processing chips in some embodiments. The processor is generally used to control the overall operation of a computer device. In this embodiment, the processor is used to run program codes stored in a memory or process data.

In addition, it should be noted that the controller 100 in this embodiment can be connected to some input and output devices, such as a display, keyboard, mouse, remote control, etc. The display can display the real-time positions of each hydraulic cylinder 4 in the adjustment stage during the operation of the equipment, as well as the real-time images collected by the camera installed inside the working space, etc. The keyboard, mouse, and remote control can be used to modify the adjusted point layout diagram input into the controller 100, or manually adjust the point layout of the hydraulic cylinder 4 at the work site to ensure that the distribution of the adjusted hydraulic cylinder 4 is closer to the on-site operation requirements, etc.
