Description

Technical Field

[0001] This utility model relates to the field of suspended workbench technology, and in particular to a suspended workbench for high-altitude tunnel top operations. Background Technology

[0002] Maintenance and installation work at the top of high-altitude tunnels typically requires the use of suspended work platforms. Workers first enter the platform, then it is raised and lowered to the working height, and finally, the workers complete the various high-altitude tasks within the platform. Traditional work platforms are mostly fixed structures, unable to move horizontally, resulting in low construction efficiency. Furthermore, working inside the tunnel carries the potential risk of falling objects. Conventional work platforms lack upper protection devices, thus posing certain risks to workers.

[0003] A track-mounted mobile lifting platform disclosed in announcement number CN221720447U belongs to the field of lifting platforms and is used for high-altitude operations such as maintenance and installation in track tunnels. It solves the safety protection problem of high-altitude workers in any posture. It includes a ladder, a work platform, a guide frame for moving along the tunnel wall, and a base frame for moving along the track. The base frame is installed at the bottom of the ladder, the guide frame is installed at the top of the ladder, the work platform includes a working platform and a safety railing, the working platform is installed at the upper part of the ladder, and the safety railing is semi-enclosed and installed on the working platform. The width of the safety railing matches the width of the ladder.

[0004] While the aforementioned patent solves the safety protection problem for workers at height in any position, the movement of the work platform requires the cooperation of ground personnel for traction or control, resulting in the need for multiple people to work together. At the same time, the work platform working in the tunnel lacks a top protection mechanism, requiring workers to be extra distracted to avoid potential falling objects, reducing work efficiency and increasing psychological burden.

[0011] As a further embodiment of this utility model, the bottom of the base plate is threaded with four sets of connecting rods, and the bottom of the four sets of connecting rods is provided with pulleys, which facilitate movement.

[0012] As a further embodiment of this utility model, the second robotic arm is rotatably connected to one side of the fence, and the second robotic arm is rotatably connected to one end of the first robotic arm.

[0015] (III) Beneficial Effects

[0016] This utility model provides a suspended work platform for high-altitude tunnel top operations, which has the following advantages:

[0017] 1. This suspended work platform for high-altitude tunnel top operations, through the setup of a base plate, control panel, translation mechanism, and lifting mechanism, allows for easy operation. First, the worker enters the work platform, controls the control panel, and activates hydraulic cylinders C and D to raise or lower the platform to the working height. During the raising and lowering process, the platform remains vertical. After reaching the working height, hydraulic cylinder B is activated to hold the platform in place, preventing swaying. Hydraulic cylinder A is then activated to translate the platform. The operation can be completed by a single worker, thus avoiding equipment collisions and jams caused by signal delays or misjudgments between ground command and high-altitude operations in traditional transmission modes. This reduces the probability of track deviation and lowers labor costs.

[0018] 2. This suspended work platform for working at the top of high-altitude tunnels, through the installation of railings and protective mechanisms, avoids potential falling objects from the tunnel ceiling during high-altitude work. First, pull the spring pin outwards and rotate it to prevent the spring inside from rebounding. Then, pull the telescopic frames on both sides upwards to the appropriate height. Rotate the spring pin in the opposite direction. Under the action of the spring force, the spring pin inserts into the adjustment hole, and the position of the telescopic frame is fixed. Rotate the baffle to the horizontal position, and the position of the baffle is fixed under the support of the telescopic frames on both sides. Thus, the workers do not need to frequently look up to observe potential hazards above, improving their focus and work efficiency, and reducing the risk to personnel caused by potential falling objects.
