Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary tools for municipal construction, and specifically relates to a trench protection device that is easy to disassemble. Background Technology

[0002] With the rapid development of cities, urban municipal engineering projects are also being upgraded and replaced. The repair of underground pipelines inevitably requires manual trench excavation. To ensure the safety of workers, support structures are usually installed in the excavated trenches to prevent them from collapsing. However, existing trench protection structures are large in size and difficult to install, requiring fasteners for fixation, which increases the construction period. Therefore, it is very important to obtain a trench protection device that is easy to disassemble. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a trench protection device that is easy to disassemble, including at least two abutting structures and a support structure that connects the two abutting structures and abuts the protective plates of the two abutting structures against the inner walls of the two sides of the trench.

[0004] The abutting structure includes a first tube and a second tube, wherein the second tube is inserted into the first tube so that the first tube and the second tube are retractably connected.

[0005] The contact structure also includes two sets of spaced-apart support limiting members. Each support limiting member includes a first limiting rod and a second limiting rod hinged to the first limiting rod. One end of each support limiting member is hinged to the first tube body, and the other end is hinged to the second tube body. The gap between the two support limiting members forms a slot for inserting the protective plate.

[0006] The support structure includes a first support rod and a second support rod hinged in the middle.

[0007] Through the above technical solution, this utility model can be folded up and stored when not in use, and can be unfolded when put into use. After the protective plate is inserted, it is supported by the support structure to prevent the collapse of the two side walls of the trench from causing injury to the construction personnel.

[0008] As a preferred embodiment, rollers are connected to the bottom of both the first and second tubes, and through holes are provided on the first and second tubes. A lower insert is inserted into the through hole, with at least a portion of the lower insert inserted into the bottom of the groove and at least a portion placed inside the through hole.

[0009] With the above technical solution, the roller is easy to move, and after the moving position is adjusted, it can be inserted into the lower insert to achieve positioning.

[0010] As a preferred embodiment, the inner wall of the protective plate is provided with several limiting grooves for the engagement of the first support rod and the second support rod. The first and second support rods have identical structures, each including a fixing rod and abutment blocks connected to both ends of the fixing rod by springs. The outer wall of the abutment block is curved.

[0011] Through the above technical solutions, the spring setting can increase the resistance effect, and the limiting groove can increase the connection stability.

[0012] As a preferred embodiment, both the first tube and the second tube are fixed with U-shaped slots, and the openings of the two U-shaped slots are arranged opposite to each other.

[0013] The outer wall of the protective plate has protrusions that extend beyond the outer wall of the U-shaped slot, which are integrally formed to help stabilize the inner wall of the groove.

[0014] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, is easy to disassemble and assemble, and does not require the use of wrenches or fasteners, thus playing a role in preventing the collapse of the inner wall of the trench.

The specific and direct description of related structures is only for the convenience of understanding this utility model, and the specific features do not necessarily or directly limit the scope of implementation of this utility model.

[0023] Referring to the accompanying drawings, the present invention adopts the following technical solution: the present invention provides a trench protection device that is easy to disassemble, including at least two abutting structures 1 and a support structure 3 that connects and abuts the protective plates 2 of the two abutting structures 1 against the inner walls of both sides of the trench.

[0024] The contact structure 1 includes a first tube 4 and a second tube 5, wherein the second tube 5 is inserted into the first tube 4 so that the first tube 4 and the second tube 5 are retractably connected.

[0025] The contact structure 1 also includes two sets of spaced-apart support limiting members 6. Each support limiting member 6 includes a first limiting rod 7 and a second limiting rod 8 hinged to the first limiting rod 7. One end of each support limiting member 6 is hinged to the first tube 4 and the other end is hinged to the second tube 5. The gap between the two support limiting members 6 forms a slot 9 for inserting the protective plate 2.

[0026] The support structure 3 includes a first support rod 10 and a second support rod 11 that are hinged in the middle.

[0027] Through the above technical solution, this utility model can be folded up and stored when not in use, and can be unfolded when put into use. After the protective plate 2 is inserted, it is supported by the support structure 3 to prevent the collapse of the two side walls of the trench from causing injury to the construction personnel.

[0028] As a preferred embodiment, the bottom of the first tube 4 and the second tube 5 are both connected to rollers 12. The first tube 4 and the second tube 5 are provided with through holes 13. A lower insert 14 is inserted into the through hole 13. The lower insert 14 is at least partially inserted into the bottom of the groove and at least partially placed in the through hole 13.

[0029] Through the above technical solution, the roller 12 is easy to move, and after the moving position is adjusted, it can be inserted into the lower insert 14 to achieve positioning.

[0030] As a preferred embodiment, the inner wall of the protective plate 2 is provided with a plurality of limiting grooves 15 for the engagement of the first support rod 10 and the second support rod 11. The first support rod 10 and the second support rod 11 have the same structure, each including a fixing rod and abutment blocks 20 connected to both ends of the fixing rod by springs 21. The outer wall of the abutment block 20 is arc-shaped.

[0031] Through the above technical solution, the setting of spring 21 can increase the resistance effect, and the limiting groove 15 can increase the connection stability.
