Description

Medium voltage system

The invention is a medium-pressure system, especially designed and manufactured for the operation in the working well of the steel caisson of the sewage engineering, so as to provide a method that can conveniently recycle all the steel rings in the working well of the steel caisson of the sewage engineering. Pressure system structure.

According to the current operation of the steel caisson working well of the sewage project, multiple sets of steel rings for support are sequentially installed on the wall of the steel caisson working well of the sewage project, and then poured with concrete. In order to make the steel rings can To facilitate hanging, assembly and disassembly, these steel rings are mainly composed of several steel ring pieces.

However, after the underground work of the steel caisson working well of the sewage project is completed, these steel rings are easily affected by the geological environment and machinery, making it impossible to hang all the steel rings in the steel caisson working well of the sewage project, resulting in Most of the steel caisson working shafts for each sewage project will have at least one set of steel rings left in them, which leads to waste. Moreover, operators must continue to purchase or make steel rings in order to provide steel caisson work for sewage projects at other sites. Well used, there is a shortcoming that needs to be improved to increase the overall cost.

The purpose of the present invention is to improve the above-mentioned shortcomings and provide a medium-pressure system structure that can easily recycle all the steel ring sheets in the working well of the steel caisson of sewage engineering.

In order to achieve the above object, the medium pressure system of the present invention is composed of a plurality of arc-shaped steel ring seats. These steel ring seats can be assembled to form annular steel rings; the inner sides of these steel ring seats are evenly spaced. A number of supporting ribs are provided, and a receiving space is formed below the supporting ribs. The lower side wall of the steel ring seat is provided with a perforation relative to the lower part of the supporting ribs. The receiving space can accommodate the hydraulic cylinder and allow the oil to be placed therein. The output shaft of the hydraulic cylinder corresponds to the perforation provided at the bottom of the steel ring seat, and the other end of the hydraulic cylinder is pressed against the bottom of the supporting rib; in addition, the steel ring seat is provided with a number of reinforcing ribs, and these reinforcement ribs The rib systems are respectively located on the side of the top rib;

Through the above structure, a medium pressure system structure is provided that can easily recycle all the steel ring pieces in the working well of the steel caisson of the sewage project.

Regarding the technical means and structures used to achieve the purpose of the present invention, the detailed description is as follows with reference to the embodiments shown in Figures 1 to 4:

As shown in Figures 1 and 2, the medium pressure system 10 of the present invention is composed of a plurality of arc-shaped steel ring seats 11. These steel ring seats 11 can be assembled to form a circular steel ring (such as The figure shows four sets of steel ring seats 11); the inner sides of these steel ring seats 11 are provided with a number of supporting ribs 111, and an accommodation space 112 is formed below the supporting ribs 111. The lower side walls of the steel ring seats 11 are opposite to each other. A perforation 113 is provided below the resisting rib 111. The accommodation space 112 can accommodate the hydraulic cylinder 20, and the output shaft 21 of the hydraulic cylinder 20 is corresponding to the perforation 113 provided at the bottom of the steel ring seat 11. The other end of the hydraulic cylinder 20 is pressed against the bottom of the resisting rib 111; in addition, the steel ring seat 11 is provided with a number of reinforcing ribs 114, and these reinforcing ribs 114 are respectively provided on the sides of the resisting rib 111.

Based on the above, a preferred embodiment is that a positioning member 115 is provided between the inner side of the steel ring seat 11 and the reinforcing rib 114. The positioning member 115 is used to position and fix the hydraulic cylinder 20 so that the hydraulic cylinder 20 does not deviate from the accommodation space. 112 breaks away and falls, so that the hydraulic cylinder 20 can provide smooth progress of the lifting operation.

Based on the above, the medium-voltage system 10 can be split into a plurality of arc-shaped steel ring seats 11 according to the needs, which can be divided into 4 groups, 5 groups, 6 groups, etc. to provide personnel with convenient, safe and fast operations.

Based on the above, the resisting ribs 111 and the hydraulic cylinder 20 can be provided with multiple groups according to the requirements. As shown in Figures 1 and 2, there are five resisting ribs 111 and five groups of hydraulic cylinders 20; however, the present invention It is not limited to this, it can also be provided with four supporting ribs 111 and four hydraulic cylinders 20, or eight supporting ribs 111 and eight groups of hydraulic cylinders 20; and the reinforcing ribs 114 can also be adjusted according to needs. The number of settings.

With the above structure, when the steel caisson working well of the sewage project is operated, the steel ring seats 11 of the medium pressure system 10 of the present invention can be arranged at the bottom of the steel caisson working well of the sewage project in sequence, so that these steel ring seats 11. According to the side wall of the working well of the steel caisson of the sewage project, a steel ring is assembled and fixed to form an annular shape. Then several sets of steel ring pieces 30 can be placed sequentially on the medium pressure system 10 of the present invention (as shown in Figure 3). Personnel can be provided to carry out operations in the working well of the steel caisson of the sewage project.

When the work in the well is completed and the concrete pouring operation is completed, preparations begin to hang out the steel ring pieces 30 in the working well of the sewage engineering steel caisson; at this time, due to the hydraulic cylinder installed on each steel ring seat 11 The output shaft 21 of 20 corresponds to the through hole 113 at the bottom of the steel ring seat 11, and controls and drives the hydraulic cylinders 20, so that the output shaft 21 of each hydraulic cylinder 20 bears against the bottom of the steel caisson working well of the sewage project, by The hydraulic cylinders 20 continuously output power, so that the steel ring seats 11 can be driven by the hydraulic cylinders 20 to lift and move upward, and the steel ring pieces 30 carried on the steel ring seats 11 also follow the steel ring seats. 11 is lifted and moved upward simultaneously (as shown in Figure 4). At this time, since the steel ring pieces 30 are no longer in close contact with the wall of the steel caisson working shaft of the sewage project, workers on the ground can use the hanging The machine tool lifts the steel ring pieces 30 out of the steel caisson working well of the sewage project in sequence, and then disassembles the medium-pressure system 10 of the present invention and lifts it out to achieve these goals. The steel ring piece 30 and the medium pressure system 10 are recycled, and these equipment can be moved to another sewage project steel caisson working well or case site for reuse.

In particular, since the present invention installs several sets of hydraulic cylinders 20 on the steel ring seat 11, when the output shaft 21 of the hydraulic cylinder 20 extends, it can pass through the through hole 113 provided at the bottom of the steel ring seat 11 and Press against the bottom of the working well of the steel caisson of the sewage project, and then the steel ring seat 11 can be driven to move upward. At this time, the steel ring piece 30 in the working well of the steel caisson of the sewage project can be driven by the steel ring seat 11 And can move upward synchronously, so that these steel ring pieces 30 and the soil wall of the steel caisson working shaft of the sewage project are loosened and no longer closely fit, so that the resistance between the two is indeed reduced, and the staff can use hanging equipment to lift it. All the steel ring pieces 30 installed in the working shaft of the steel caisson of the sewage project are lifted out for recycling, and since the steel ring pieces 30 are already loose, the hanging equipment can successfully hang the steel ring pieces 30 without consuming large amounts of power. After all the steel ring pieces 30 have been recovered, the staff will lift the steel ring seats 11 away from the steel caisson working shaft of the sewage project, thus achieving the effect of recycling the entire equipment without the steel ring pieces. 30 is too tightly attached to the wall surface of the steel caisson working shaft of the sewage project and cannot be moved and remains in the steel caisson working shaft of the sewage project. There will be no waste of the steel ring piece 30 and an increase in costs.

In particular, the steel ring seat 11 of the present invention is provided with abutting ribs 111 and reinforcing ribs 114, and the hydraulic cylinder 20 is located below the abutting ribs 111. Therefore, it can not only reduce the volume and length of the hydraulic cylinder 20 In addition, the use of the resisting ribs 111 and the reinforcing ribs 114 can increase the load-bearing strength of the steel ring seat 11 so that the steel ring seat 11 will not be deformed during the process of carrying the steel ring piece 30 and being driven by the hydraulic cylinder 20 to lift.

Therefore, from the above, it can be known that the medium pressure system 10 of the present invention is installed at the bottom of the working well of the steel caisson in the sewage project and the steel ring pieces 30 are installed. After the operation is completed, the staff can surely remove these steel ring pieces. 30 All the steel caisson working wells of the sewage project are lifted off for recycling and reuse, thereby achieving recycling and reusability, effectively reducing costs, and reducing resource waste; therefore, the present invention is indeed progressive and practical, and its method is accurate As this has never happened before, I sincerely meet the requirements for an invention patent. I file a patent application in accordance with the law and pray for the patent to be granted.

However, the above are only possible embodiments of the present invention. These embodiments are mainly used to illustrate the technical means and structures used to achieve the purpose of the present invention. Therefore, they cannot be used to limit the scope of protection of the present invention. Any equivalent changes or modifications made based on the description of the invention and the scope of the patent application shall still fall within the scope of protection covered by the invention.
