Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a track-type sliding support for a bridge maintenance platform. Background Technology

[0002] As a critical node in transportation networks, the structural safety of bridges is paramount, thus requiring regular inspection and maintenance. During bridge maintenance, mobile maintenance platforms are typically used to provide workers with a safe working space that allows them to move along the bridge structure.

[0003] In actual maintenance work, workers not only need to stand on the platform but also need to carry and use various tools and spare parts. Existing maintenance platforms are often designed with only the platform's mobility and load-bearing capacity in mind, neglecting the effective management of accompanying tools. Workers typically need to carry their own toolkits or leave tools haphazardly on the platform, which is not only inconvenient and inefficient but also poses a safety hazard due to tools slipping and falling.

[0004] Furthermore, as a high-altitude work platform, safety guardrails are an essential component. Existing guardrails present inconveniences in terms of installation and dismantling. Some guardrails have complex structures, requiring significant time for installation, reducing the efficiency of work preparation and completion; while other platforms, in order to simplify their structure, lack sufficient protective robustness. This lack of functional integration significantly reduces the convenience and overall efficiency of existing maintenance platforms in practical use.

[0005] Therefore, this utility model proposes a track-type sliding support for a bridge maintenance platform to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a track-type sliding support for bridge maintenance platforms, aiming to improve the problems of existing track-type sliding supports for bridge maintenance platforms, such as limited functionality, lack of integrated tool storage structure, and cumbersome installation and disassembly of safety protection devices.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a track-type sliding support for a bridge maintenance platform, comprising a track beam and a support frame, wherein the bottom of the support frame is provided with sliding wheels that slide in cooperation with the track beam. The support frame also includes an integrated storage mechanism and a protective mechanism.

[0008] The storage mechanism is detachably clamped and fixed to the outer wall of the support frame.

[0009] The protective mechanism is rotatably connected to the support frame, and the protective mechanism also includes a locking component for locking it in the deployed protective position.

[0010] Preferably, the storage mechanism includes a first clamp and a second clamp that cooperate with each other, the first clamp and the second clamp are rotatably connected by a pin, and a torsion spring that provides clamping force is provided between the first clamp and the second clamp.

[0011] Preferably, the storage mechanism further includes a toolbox, which is suspended and connected to the tail of the second clamp via a connecting ring.

[0012] Preferably, the protective mechanism includes a guardrail and a guardrail, the guardrail being hinged to the guardrail, and the guardrail being hinged to the support frame.

[0013] Preferably, the protective mechanism further includes a first fixed post and a second fixed post fixed to the support frame. The first fixed post provides a fixed support for the guardrail, and the second fixed post provides a fixed support for the guard rod.

[0014] Preferably, the protective mechanism further includes a fixing block, which is disposed on the support frame to support the protective rod.

[0015] Preferably, one side of the fixing block is provided with a baffle to prevent the guard rod from tilting along that side.

[0016] Preferably, the locking assembly includes a support block, a screw, and a nut; the support block is detachably fixed to the outer wall of the protective rod, the screw passes through the support block and the support frame in sequence, and cooperates with the nut to lock the protective rod to the support frame.

[0017] This utility model has the following beneficial effects: 1. In this utility model, a storage mechanism that uses spring clamps to quickly hold and fix the toolbox is set on the support frame. This storage mechanism can conveniently hang the toolbox, which solves the problem that the existing bridge maintenance platform lacks an integrated tool storage solution and the tool is inconvenient to access.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3 One embodiment of this utility model is a track-type sliding support for a bridge maintenance platform, which aims to solve the problems of existing bridge maintenance platforms having limited functions, lacking integrated tool storage structures, and having cumbersome installation and disassembly of safety protection devices.

[0023] The bridge maintenance platform track-type sliding support includes a track beam 1 and a support frame 3. The bottom of the support frame 3 is equipped with sliding wheels 2, which slide in cooperation with the track beam 1, allowing the support frame 3 to move smoothly on the track beam 1, providing a mobile platform foundation for maintenance operations. The support frame 3 is also integrated with a storage mechanism 4 and a protective mechanism 5. The storage mechanism 4 is used to conveniently store maintenance tools and is detachably clamped and fixed to the outer wall of the support frame 3. The protective mechanism 5 provides safety protection for maintenance operations. The protective mechanism 5 is rotatably connected to the support frame 3 and includes a locking component for locking the protective mechanism 5 in the unfolded protective position to achieve quick switching between the protective state and the folded storage state.

[0024] The storage mechanism 4 includes a first clamp 401 and a second clamp 402 that cooperate with each other. The first clamp 401 and the second clamp 402 are rotatably connected by a pin 403. A torsion spring 404 is provided between the first clamp 401 and the second clamp 402. The torsion spring 404 provides elastic force for the clamping action of the first clamp 401 and the second clamp 402, so that the clamping part composed of the first clamp 401 and the second clamp 402 can be detachably clamped and fixedly installed on the outer wall of the support frame 3, providing a stable foundation for subsequent suspension. The storage mechanism 4 also includes a toolbox 406, which is suspended and connected to the tail of the second clamp 402 by a connecting ring 405. This detachable structure that uses the torsion spring 404 to provide clamping force enables the quick installation and removal of the toolbox 406, providing a convenient tool storage solution for maintenance operations.

[0025] The protective mechanism 5 includes a guardrail 501 and a guardrail 503. The guardrail 503 is hinged to the guardrail 501, and the guardrail 501 is also hinged to the support frame 3. This double-hinged structure allows the guardrail 501 and the guardrail 503 to be folded and unfolded as a whole relative to the support frame 3.

[0026] To provide stable support in the deployed state, the protective mechanism 5 also includes a first fixed post 502 and a second fixed post 505 fixed to the support frame 3. The first fixed post 502 is used to provide a fixed support base for the guardrail 501, and the second fixed post 505 is used to provide a fixed support base for the guardrail 503, thereby ensuring the rigidity and stability of the protective structure in the working position.

[0027] Furthermore, the protective mechanism 5 also includes a fixing block 504 disposed on the support frame 3. The fixing block 504 is used to support the protective rod 503 in the unfolded state. A baffle is also provided on one side of the fixing block 504. The baffle provides a one-way limit for the protective rod 503, effectively preventing the protective rod 503 from tilting along this side.

[0028] As a specific structure for realizing the locking function, the locking component includes a support block 506, a screw 507 and a nut 508. The support block 506 is detachably fixed to the outer wall of the protective rod 503 during use. The screw 507 passes through the support block 506 and the support frame 3 in sequence and is threaded with the nut 508. By tightening the nut 508, the protective rod 503 can be firmly locked onto the support frame 3.

[0029] Working principle: When bridge maintenance is carried out, the track beam 1 is first laid in a suitable position on the bridge to provide a stable path for the movement of the support. Then, the sliding wheel 2 installed on the support cooperates with the track beam 1 and drives the support frame 3 to move on the track beam 1 with the help of external force. During the movement, the support frame 3 plays a key supporting role to ensure that the entire support system remains stable when the sliding wheel 2 moves and the maintenance work is carried out. When tools need to be stored, storage mechanism 4 is used. The first clamp 401 and the second clamp 402 cooperate with each other and are connected and rotated by the pin 403. At the same time, the torsion spring 404 provides elastic force for the clamping action of the first clamp 401 and the second clamp 402, so that the first clamp 401 and the second clamp 402 can be firmly clamped on the outer wall of the support frame 3, providing a stable clamping foundation for subsequent connection and suspension. Then, the tail of the second clamp 402 is connected to the toolbox 406 by the connecting ring 405, so that the toolbox 406 can be suspended in a designated position by means of the connecting ring 405, thereby realizing the storage and convenient access of tools. When protection is needed, first lift the guardrail 501. Lifting the guardrail 501 will cause the guardrail 503 to reach a state perpendicular to the support frame 3. The first fixed column 502 and the second fixed column 505 provide the foundation for fixed support of the guardrail 501 and the guardrail 503, respectively. There is a baffle on one side of the fixed block 504 to prevent the guardrail 503 from tilting to one side. Next, fix the support block 506 to the outer wall of the guardrail 503. The screw 507 passes through the support block 506 and the support frame 3, and then the nut 508 passes through the screw 507 and rotates to the outer wall of the support frame 3, thereby firmly fixing the guardrail 501 and the guardrail 503 to the support frame 3, providing reliable safety protection for bridge maintenance operations. When it is necessary to fold the protective mechanism 5, remove the screw 507, remove the support block 506, and then lower the guardrail 503 along the other side of the fixed block 504 without the baffle, and it can be folded.
