Description

A steel cage roll welding machine

technical field

The utility model belongs to the field of reinforcement cage manufacturing, in particular to an inner support reinforcement installation mechanism.

Background technique

In the construction of large bridges and other projects, a large number of piles need to be constructed. In the construction of these piles, a large number of steel cages need to be processed. In the prior art, a steel cage roll welding machine is a commonly used equipment for making steel cages.

Referring to Figure 1, a common steel bar seam welding machine consists of main parts such as a sliding track, a mobile rotating disc, a fixed rotating disc, a rotating distribution rack, and a steel bar feeding rack. The working process is as follows: First, place the main steel bar on the material rack of the steel bar feeding rack, and then the hook chain will lift the steel bar up and place it on one of the positions of the rotating sub-rack. The upper position of the main rib, repeat this action until all the required main rib are loaded on the rotating sub-rack, and then manually fix the main rib fixing cylinder and the rear rebar fixing cylinder to the main rib cylinder fixing ring, and then manually calculate the fixed cylinder and the fixed cylinder. According to the angle of the center, adjust the fixed cylinder repeatedly according to the calculated angle until the position is correct, and ensure that the fixed cylinder of the main rib is evenly distributed around the circumference. Then move the mobile rotating disk to the front of the fixed rotating disk until it almost fits, and then several workers manually pull out the main steel bar from the rotating sub-rack, and then forcefully push the main steel bar through the rear steel bar fixing tube to the main steel bar fixing tube. Next, use the fastening screws on the main rib fixing cylinder to compress the main rib. A steel cage has several or dozens of main bars depending on the design. All of them must be fully worn one by one through such a manual method. After wearing, the preparation work is basically completed, and then the machine can be started. After the machine is turned on, the mobile rotating disc, the steel cage, the fixed rotating disc, the rotating distribution rack, and the main steel bars are all synchronously rotated together. At the same time, the rotating disk moves outward along the sliding track, and at the same time, the rotating main rib is also pulled out through the rear rebar fixing cylinder. After the straightening machine, it is welded on the main bar. As the machine runs and stretches, the winding bars are spirally wound to the top of the main bar. At this time, welding is applied according to the design. After the steel bars are stretched in place, the steel bar cage is basically completed. After the completion, the hydraulic roller support frame can be raised. The steel cage is supported by hydraulic roller support frame. Take out the front and rear main reinforcement sleeves, and the reinforcement cage can be hoisted and moved. At this time, the reinforcement is still in the final process. The inner support reinforcement is manually welded. The worker manually moves the inner support reinforcement made in advance to the inside of the reinforcement cage for alignment and welding. After completion of the reinforcement The cage is finished. The above process can be simplified as: artificial circular array main reinforcement → welding around the reinforcement → manual welding of the inner support reinforcement. It can be clearly seen that there are a large number of manual non-welding operations in the existing steel cage seam welding machine, which seriously affects the production efficiency of the steel cage.

The steel cage winding machine in the second prior art is composed of a winding machine roller and a mobile winding machine. The working conditions are as follows: First, the worker holds the inner support bar and the main bar to maintain the welding position, and then manually welds until the main bar and the inner support bar are all welded in place. At this time, the roller of the winding machine is turned on to rotate, which in turn drives the main structure of the reinforcement cage composed of the inner support bar and the main reinforcement to rotate, and then moves the winding machine to start winding the reinforcement, and wraps the reinforcement on the main structure of the reinforcement cage until it is completed. The efficiency of such a steel cage manufacturing process is even lower.

Therefore, the applicant believes that it is necessary to develop a reinforcement cage seam welding machine that can greatly improve the production efficiency of reinforcement cages.

Optionally, the walking track is two I-beams arranged in parallel, and the length of the I-beam is longer than the steel cage. length. Two moving tables are symmetrically arranged on the track, and a support and fixed seat sleeve 31 is fixed on the moving table by welding or other equivalent methods. A support frame main shaft 33 is installed in the support and fixed seat sleeve 31 through bearings, and the other end of the support frame main shaft 33 passes through. A sliding guide bush 35 is fixedly connected to the flange or other equivalent means. The axes of the supporting and fixing seat sleeve 31 and the main shaft 33 of the supporting frame are both collinear with the first straight line X.

A motor or other equivalent output mechanism is installed in the moving table, and the output shaft of the mechanism can selectively transmit power to the internal transmission shaft 37 or the main shaft 33 of the support frame. It is easy to understand that the interior of the mobile platform is a power source, and the purpose is to provide power for the rotation of the internal drive shaft 37 or the main shaft 33 of the support frame, and the specific implementation of its internal structure does not affect the implementation of the technical solution in this case. According to common knowledge and prior art, it is known how to choose and implement its internal structure, so it will not be repeated in this case.

The rotation of the main shaft 33 of the support frame will drive the sliding bushing 35 and its upper parts, that is, the overall rotation of the inner support bars at the head and tail, so as to realize the rotation indexing of the inner support bars, so that the relative positions of the multiple main bars on the side walls of the inner support bars conform to the design Require. In the prior art, this step is completed by rotating the material distribution rack and the main reinforcement fixing cylinder, which manually fixes the main reinforcement fixing cylinder and the rear reinforcement fixing cylinder to the fixing ring of the main reinforcement cylinder, and then manually calculates the distance between the fixing cylinder and the center. Adjust the fixed cylinder according to the calculated angle repeatedly until the position is correct, and ensure that the main rib fixed cylinder is evenly distributed around the circumference. Compared with the prior art, in this embodiment, manual operation is replaced by mechanically driving the overall rotation of the support frame, the inner support bars and the steel cage, which greatly improves the indexing efficiency of the main bars and reduces the labor intensity of workers.

When the inner drive shaft 37 rotates, the inner rotation shaft 37 drives the double-threaded tightening power rod 39 to rotate, because the thread rotation directions of the threaded segments at both ends of the double-threaded tightening power rod 39 are opposite, and because the guide hole 351 restrains the protrusion, The left moving seat 38 and the right moving seat can only move in translation, that is, the double-threaded tightening power rod 39 drives the correspondingly sleeved left moving seat 38 and the right moving seat in opposite sliding directions. When the left moving seat 38 and the right moving seat move towards each other, the distance becomes smaller, the distance between the bottom end of the left support rod 36 and the bottom end two of the right support rod becomes smaller, the top end one and the top end two are far away from the sliding guide sleeve 35, forcing the inner support The extender 34 is away from the sliding guide bush 35 . When the left moving seat 38 and the right moving seat move in opposite directions, when the distance becomes larger, the distance between the bottom end of the left support rod 36 and the bottom end two of the right support rod becomes larger, and the top end one and the top end two are close to the sliding guide sleeve 35, forcing the The inner strut extender 34 is close to the sliding guide sleeve. The grooves of the inner support extenders connected on the circumferentially arranged movable support rods are fitted into a circle with a variable diameter, so as to activate/uninstall the support of the inner support bars from the inside.

The support arm 22 can drive the inner support rib to clamp the machine head to open and close. When the support arm 22 is unfolded, the head of the inner rib clamping machine is far away from the traveling device, and tends to approach the estimated space of the steel cage to be produced on the seam welding machine, so as to facilitate the subsequent process to clamp the inner rib to the inner brace Rib gripping machine head. When the welding of the reinforcement cage is completed, the inner support rib clamping head releases the clamping of the inner support reinforcement, and the support arm retracts at this time, thereby driving the inner support reinforcement head away from the reinforcement cage space on the seam welding machine table, and close to the walking device. At this point, within the cylindrical space occupied by the completed rebar cage, there is no additional mechanism to hinder the hoisting and hoisting operations of the rebar cage.

This embodiment can conveniently and quickly make the middle-section inner rib clamping mechanism reach the working position to clamp the inner rib, which facilitates subsequent welding of the main rib to the inner rib.

Preferably, the laser range finder 510 is detachably installed on the upper end surface of the fixed-length baffle 55 . That is, in space, the laser range finder 510, the fixed-length baffle 55, and the trolley body 5301 are arranged in sequence from top to bottom, so as to avoid mutual interference of various functional components and provide system reliability and stability. In some embodiments, the laser range finder 510 is located on the axial direction of the main rib of the main rib feeding rack 51 , and the laser range finder emits a laser signal. After the laser signal is emitted to the end face of the main rib, the reflected signal is detected by the laser range finder 510 take over. The laser range finder 510 transmits the measured information to the console PLC, and the console PLC calculates the predetermined position of the fixed-length pulley 53 on the track 52 according to the design position of the main rib, drives the drive reducer 57 to start, and the fixed-length pulley 53 starts to slide on the track 52, and when it reaches the predetermined position, the console PLC controls the braking device to start, the telescopic cylinder 58 drives the brake block 59 to brake, and the fixed-length pulley 53 is fixed at the calculated predetermined position.

In order to ensure the measurement accuracy of the laser range finder and simplify the calculation process of the console PLC, in some embodiments, the fixed-length pulley 53 has a first position on the track 52, and in the initial state and when the main reinforcement is in place, the fixed-length pulley 53 is in place. 53 is always in the first position. In some embodiments, the first position of the fixed-length pulley 53 is the end of the track 52 away from the main rib.

In order to improve the reliability of signal transmission and avoid the loss of transmission signals, in some embodiments, a cable is used for wired connection. Optionally, a receiving wire box 511 is fixed in parallel below the rail 52, and the receiving wire box 511 is also fixed on the main rib feeding rack 51 by welding, bolt and nut assemblies or other equivalent methods. A drag chain 512 is arranged in the storage wire box 11 , and one end of the drag chain 512 is connected with the storage wire box 511 , that is, a part of the drag chain 512 slides relatively in the storage wire box 511 . The other end of the towline 512 is connected to the fixed-length pulley 53 , that is, the other end of the towline 512 is detachably fixed on the fixed-length pulley 53 . Cables are arranged in the drag chain 512, and the console PLC is electrically connected to the laser range finder, the driving device and the braking device respectively through the cables.

In a specific embodiment, its working process is as follows:

The steel cage seam welding machine is set horizontally, that is, the first straight line X, the second straight line, and the third straight line Y are located on the same horizontal plane, and the fourth straight line Z is located on the plumb plane. A walking track composed of two parallel I-beams is fixed on the ground, two mobile platforms are symmetrically installed on the walking track, a supporting frame 3 is correspondingly arranged on the mobile platform, and on the ground between the two supporting frames 3 Along the first straight line X, a plurality of inner braces are arranged horizontally to clamp the driver 2 , and a plurality of hydraulic telescopic support frames 4 are also arranged on the running track between the two support frames 3 . The inner rib clamping driver 2 and the hydraulic telescopic support frame are symmetrically arranged one by one.

Place the head and tail inner braces on the left and right support frames 3, the power transmitted inside the mobile table drives the internal rotation shaft 37 to rotate, and drives the double-threaded tightening power rod 39 to rotate. The rotation directions of the threads are opposite, and at the same time, due to the guide hole 351 constraining the protruding portion, the left movable seat 38 and the right movable seat can only move in translation, that is, the double-threaded tightening power rod 39 drives the corresponding left movable seat 38 sleeved on it. , The sliding direction of the right movable seat is always opposite. When the left movable seat 38 and the right movable seat move toward each other, the distance becomes smaller, the distance between the bottom end of the left support rod 36 and the bottom end 2 of the right support rod becomes smaller, and the top end 1 and the top end 2 are far away from the sliding guide sleeve 35, forcing the inner support The extender 34 is away from the sliding guide bush 35 . The grooves of the inner support extenders connected on the circumferentially arranged movable support rods are fitted into a circle with a variable diameter until the circle coincides with the inner support bars, that is, the head and tail inner support bars are fixedly supported.

Then, the support arm 22 is driven away from the feeding rack body 51 by the support telescopic cylinder until it is located on the third straight line Y, and the rest of the inner support ribs at the middle end are placed on the arc groove 22, and the telescopic cylinder is activated to press the sheave. Fix the inner rib on the inner rib clamping head, and then drive the inner rib clamping head along the third straight line Y to enter between the two support frames 3 through the sliding of the feeding frame body 51 on the feeding frame base. between. At this time, the hydraulic telescopic support 4 is activated, and the idler 452 of the arc-shaped support assembly 45 is in contact with the bottom of the inner brace. The second telescopic cylinder 412 drives the arc-shaped support assembly 45 to move up and down on the fourth straight line Z, the traveling device drives the inner strut to move back and forth on the third straight line Y, and the telescopic cylinder is applied to the inner strut in the middle section through the sheave. The compression force is adjusted to adjust the inner support bar in the middle section, and finally the inner support bar at the head and tail and the inner support bar in the middle section are concentric.

When making a reinforcement cage, the above steps can be repeated to adjust the position of the inner reinforcement.

After the preliminary work is completed, the main reinforcement can be welded, and the main reinforcement can be placed flat on the reinforcement placement rack 518, and the telescopic cylinder is activated, and the reinforcement will slide along the conveying slope 517 inside the feeding rack body 1 to the hooked reinforcement lifting chain 515. The hook on the lifting chain 515 with hooks lifts the main bars to the main bar rolling bracket 519 at a frequency of one bar at a time, and then the console PLC starts the laser range finder, and the laser range finder 510 emits a laser to the end face of the main bar , the end face of the main rib reflects the laser signal to the laser range finder 510, the console PLC calculates the correct movement amount of the fixed-length pulley 3 from the first position to the predetermined position according to the predetermined position of the main rib in the segmented reinforcement cage, and then sends out The movement signal is transmitted to the drive reducer 7 and the telescopic cylinder 8 through the cable in the storage box 12. At this time, the telescopic cylinder 8 releases the brake state, the drive reducer 7 starts, and the fixed-length pulley 3 is pushed forward, and then fixed to the length. The baffle 5 pushes the main rib of its front section to a predetermined position, and then the fixed-length pulley 3 as a whole automatically retracts to the first position, the brake is activated again, and the entire fixed-length process is completed.

Push the main rib to the correct position. At this time, the worker stands on the welder's walking frame 516, and pushes the main rib sideways to make the inner support rib and the main rib fit.

Next, the left and right moving tables output power synchronously with the inner support rib holder, that is, the rotation of the main shaft 33 of the support frame will drive the sliding bushing 35 and its upper parts, that is, the overall rotation of the head and tail inner support ribs, so as to realize the rotation indexing of the inner support ribs. , so that the relative positions of multiple main bars on the side walls of the inner support bars meet the design requirements. At the same time, the drive wheel assembly in the arc-shaped slot, that is, the second sheave, drives the inner support bars in the middle section to rotate.

After rotating in place, the next main rib is lifted to the main rib rolling bracket 519 through the same steps, the laser ranging system calculates and executes its correct position again, the worker also pushes in the welding again, and the second main rib also completes the assembly welding , and so on, the next main bars are also assembled and welded in place one after another, until the main bars are welded to about two-thirds of all the main bars, they can be released and the inner support bars can be retracted through the bracket recovery cylinder to hold the driver, and the inner support bars are clamped. The drive is in close contact with the frame body 51 of the feeding rack.

After there is no inner rib to clamp the driver, continue to rotate the inner rib through the support frame 3 and repeat the welding of the remaining main ribs until all the main ribs are welded and evenly distributed on the inner rib. At this time, another step is completed. At this time, the semi-finished steel cage is continuously rotated under the driving of the left and right moving tables. The moving winding machine is composed of pulling out the rib, and the rib is welded on a main rib, and it is rotated and advanced, and welding is carried out at the same time, and the winding is completed. , cut off the winding bars, and the steel cage will complete the whole process and become the final product.

Then the support frame 3 is released, and the support frame 3 exits the steel cage along the walking track under the drive of the moving table. At this time, the steel cage is directly hoisted, and the next steel cage can be produced. If it is to lengthen the reinforcement cage, after completion, since the position of the main reinforcement has been fixed by the length-fixing device of the main reinforcement feeding rack, it can be directly connected.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection of the utility model.
