Description

Technical Field

[0001] This utility model relates to the field of bridge maintenance equipment technology, and in particular to an operating frame for bridge maintenance. Background Technology

[0002] Bridge maintenance platforms are indispensable equipment in bridge maintenance and reinforcement projects. Their main function is to provide construction workers with a safe and stable working platform for inspecting, repairing, and reinforcing the bridge's underside. Existing suspended platforms have replaced traditional scaffolding and expensive bridge maintenance vehicles, significantly reducing maintenance costs. The main advantage is the rapid raising and lowering of the platform, reducing the time and cost of erecting scaffolding while improving work efficiency. Especially in situations where scaffolding cannot be erected on rivers, suspended platforms play an irreplaceable role.

[0003] In existing technologies, suspended platforms are composed of longitudinal and transverse steel pipes and a base plate. While they can provide protection for the user, they cannot protect against falling or placed tools, which are prone to falling downwards and causing unnecessary losses. Furthermore, they pose a danger to vehicles traveling below. Therefore, we propose a bridge maintenance operating frame to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an operating frame for bridge maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bridge maintenance operating frame includes a base plate, two side plates fixedly connected to the top of the base plate, two assembly blocks fixedly connected to the outer walls of each of the two side plates, T-shaped holes formed on the outer walls of the four assembly blocks, T-shaped columns rotatably connected to the inner walls of the four T-shaped holes, a common U-shaped frame fixedly connected between two T-shaped columns, wire mesh fixedly connected to the inner walls of the two U-shaped frames, two traction ropes fixedly connected to the outer walls of the two side plates, one end of each traction rope being fixedly connected to the outer wall of the U-shaped frame, two L-shaped pieces fixedly connected to the outer walls of the two side plates, two pads fixedly connected to the outer walls of the two U-shaped frames, and a storage mechanism provided on the outer walls of the side plates.

[0007] Preferably, the storage mechanism includes a crossbar, the two ends of which are fixedly connected to the outer walls of two side plates. Two rectangular sleeves are slidably fitted on the outer wall of the crossbar. Two connecting rods are fixedly connected to the bottom of each of the two rectangular sleeves. The same toolbox is fixedly connected to the bottom of the two connecting rods. By setting up the storage mechanism, the carried tools are stored to prevent accidental drops.

[0008] Preferably, the top of the base plate is fixedly connected to two railings, and the outer wall of the side plate has two lifting holes. Lifting ropes pass through the two lifting holes, and the plate is then lifted and lowered by an existing elevator.

[0009] Preferably, the outer walls of the four pads are slidably connected to the outer walls of the four L-shaped parts.

[0010] Preferably, the U-shaped frame and the side plate are slidably connected.

[0011] Preferably, the outer walls of the U-shaped frame, L-shaped piece and pad are all provided with insertion holes, and the inner walls of the insertion holes are threaded with bolts. When not in use, the U-shaped frame is fixed between the two side plates by bolts.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses assembly blocks, T-shaped columns, U-shaped frames, wire mesh, traction ropes, L-shaped parts, pads, and bolts to ensure that the U-shaped frames rotate outward at a fixed angle. The wire mesh acts as a barrier against falling objects or large pieces of debris that fall during bridge maintenance, reducing the danger during the maintenance process. The tools can be stored in a convenient storage mechanism, allowing for easy access, and the toolbox can be adjusted for easy use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4 As shown, a bridge maintenance operating frame is provided, including a base plate 1, two side plates 2 are fixedly connected to the top of the base plate 1, two railings 3 are fixedly connected to the top of the base plate 1, two lifting holes are opened on the outer wall of the side plates 2, and two assembly blocks 4 are fixedly connected to the outer wall of each side plate 2.

[0022] The outer walls of the four assembly blocks 4 are all provided with T-shaped holes, and the inner walls of the four T-shaped holes are rotatably connected with T-shaped posts 5. The same loop frame 6 is fixedly connected between two T-shaped posts 5. The loop frame 6 is slidably connected to the side plate 2. The loop frame 6 rotates in the T-shaped holes through the T-shaped posts 5, forming an outward rotation.

[0023] The inner walls of the two loop frames 6 are fixedly connected with wire mesh 7. The wire mesh 7 is made of nylon and has good wear resistance. The outer walls of the two side plates 2 are fixedly connected with two traction ropes 8. One end of the traction rope 8 is fixedly connected to the outer wall of the loop frame 6. The four traction ropes 8 are connected to the outer walls of the two loop frames 6 in pairs.

[0024] Two L-shaped pieces 9 are fixedly connected to the outer walls of both side plates 2, and two pads 10 are fixedly connected to the outer walls of both loop frames 6. The outer walls of the four pads 10 are slidably connected to the outer walls of the four L-shaped pieces 9 respectively. The pads 10 help the loop frames 6 align with the side plates 2. The outer walls of the loop frames 6, L-shaped pieces 9 and pads 10 are all provided with insertion holes. The inner walls of the insertion holes are threaded with bolts 15. After the bolts 15 are screwed into the threaded holes, the loop frames 6 are fixed between the two side plates 2.

[0025] The outer wall of the side panel 2 is provided with a storage mechanism, which includes a crossbar 11. The two ends of the crossbar 11 are fixedly connected to the outer walls of the two side panels 2. Two rectangular sleeves 12 are slidably fitted on the outer wall of the crossbar 11. The rectangular sleeves 12 slide linearly through the crossbar 11. Two connecting rods 13 are fixedly connected to the bottom of each of the two rectangular sleeves 12. The bottom of the two connecting rods 13 is fixedly connected to the same toolbox 14, and the connecting rods 13 support the toolbox 14.

[0026] Working principle: In use, the two side plates 2 and the base plate 1 are hoisted through the lifting holes and placed at the bottom of the bridge. The user stands on the base plate 1 and rotates the four bolts 15 to slide it out of the four holes, releasing the position fixation of the two loop frames 6. The loop frames 6 rotate through the T-shaped column 5 and the assembly block 4, while the traction rope 8 provides traction. At the same time, the loop frames 6 rotate outward at a certain angle. The wire mesh 7 acts as a barrier against falling objects or large pieces of debris that fall during bridge maintenance, preventing them from falling further. The tools can be stored in the toolbox 14. Moving the rectangular sleeve 12 moves the connecting rod 13, and the movement of the connecting rod 13 moves the toolbox 14 along the crossbar 11. The position of the toolbox 14 can be adjusted for easy use.
