[0021] As attached Figure 1 As shown, a detachable auxiliary supporting diagonal rod 16 is flange-connected between the left front end portion of the upper surface of the horizontal base frame 4 and the right rear end portion of the lower surface of the platform frame 8 .

[0022] As attached Figure 1 As shown, a detachable base frame diagonal brace 17 is flange-connected between each supporting vertical rod 6 and the lower surface of the horizontal base frame 4 .

[0023] The structural design of the detachable auxiliary support diagonal rod 16 and the detachable base frame diagonal brace 17 enhances the overall structural stability and safety of the working platform and effectively reduces the safety risks during the working process.

[0024] As attached Figure 1 As shown, a detachable ladder 18 is flange-connected between the front end of the upper surface of the horizontal base frame 4 and the front end of the lower surface of the platform frame 8 .

[0025] The detachable design of the detachable ladder 18 simplifies the transportation and assembly process and further improves the convenience of construction.

[0026] Flange connections are formed between the platform frame 8 and the detachable platform guardrail 9, between the platform frame 8 and the detachable front support diagonal rod 10, between the horizontal base frame 4 and the detachable front support diagonal rod 10, between the platform frame 8 and the detachable rear support diagonal rod 19, between the horizontal base frame 4 and the detachable rear support diagonal rod 19, between the platform frame 8 and the detachable middle support diagonal rod 11, and between the horizontal base frame 4 and the detachable middle support diagonal rod 11.

[0027] The utility model is implemented by the following steps when in use:

[0028] Step 1: According to the actual situation on site, check the construction conditions of the cable trough 3 and the tunnel side wall 2 to ensure that the operation requirements are met;

[0029] Step 2: Pre-assemble the work platform at the construction site, as shown in the attached Figure 1 ~Attached Figure 2As shown, assemble the horizontal base frame 4 with the vertical pulley 5 and the horizontal pulley 7 to ensure that the vertical pulley 5 and the horizontal pulley 7 roll smoothly. Then, install the platform frame 8 and the platform plate, and install the detachable platform guardrail 9 and the platform frame auxiliary pulley 12. The main structure of the working platform is reinforced by the detachable front support diagonal rod 10, the detachable rear support diagonal rod 19, the detachable middle support diagonal rod 11, the detachable auxiliary support diagonal rod 16 and the detachable base frame diagonal brace 17.

[0030] Step 3: Install the detachable auxiliary inclined arm Ⅰ 13, the auxiliary pulley 14 for installing the leaky cable, the detachable auxiliary inclined arm Ⅱ 15 and the detachable ladder 18 to facilitate the laying of the leaky cable 1;

[0031] Step 4: Move the assembled work platform to the side of the cable trough 3, adjust the vertical pulley 5 and the horizontal pulley 7 on the horizontal base frame 4 to enter the track of the cable trough 3, so that the vertical pulley 5 is rolled and assembled on the upper surface of the trough wall of the cable trough 3, and the horizontal pulley 7 is rolled and assembled on the inner side of the trough wall of the cable trough 3, and at the same time, the platform frame auxiliary pulley 12 is rolled and supported on the tunnel side wall 2 to ensure that the work platform is firmly against the tunnel side wall 2;

During the construction operation, the workers located at the upper part of the working platform must wear safety belts, and the workers located at the lower part of the working platform must wear safety helmets and protective clothing to prevent falling objects from the upper part of the working platform. At the same time, the workers located at the lower part of the working platform must always hold the working platform well to keep it stable and avoid moving it. After completing the buckling operation of a leaking cable 1, the workers located at the upper part of the working platform should half-squat on the working platform, be sure to fasten their safety belts and hold the handrails of the detachable platform guardrails 9 on both sides of the upper part of the working platform, and then the workers located at the lower part of the working platform can be allowed to push the working platform to the next working point. When moving the working platform, ensure that the vertical pulley 5 and the horizontal pulley 7 move smoothly on the track of the cable trough 3, and pay special attention to obstacles on the track of the cable trough 3 (uncut steel bar heads, small gravel) to ensure safety.

[0033] Step 6: After the laying of the leaky cable 1 is completed, the working platform is disassembled and the tools are sorted out to ensure that "the work is completed and the materials are gone, and the site is clear", thereby completing the use of the working platform; it overcomes the difficulties in transportation and handling of the existing leaky cable working ladders, limits the flexibility of the construction site, and the fixed structural design cannot be flexibly adjusted, which easily causes physical damage to the leaky cable 1.
