The traction rope of each winch passes around the steering wheel at the front end of the cantilever beam and then hangs down to connect with a reinforcement operation platform. The utility model uses the cantilever beam to suspend the reinforcement operation platform on the outer side of the cliff below the arch seat, and the winch controls the lifting of the platform. The arch seat reinforcement can be completed without setting up a bracket, and the construction speed is fast and the cost is low.

[0026] It should be noted that, by setting up the lifting mechanism 2, the lifting speed of the suspension platform 5 can be kept stable, and at the same time, the steel cable 3 will not contact the corner of the cliff, avoiding the occurrence of friction. By setting up the protection mechanism 4, a better protection effect can be achieved and a certain degree of safety can be improved.

[0027] like Figure 2 , Figure 3 As shown, the lifting mechanism 2 includes two connecting plates 21 and two fixed plates 24, the bottoms of the two connecting plates 21 are fixedly connected to the left and right parts behind the top of the cliff body 1, the left side of the left connecting plate 21 is fixedly connected to the motor 22, the output ends of the two connecting plates 21 are rotatably connected to the winding roller 23, the left end of the winding roller 23 is fixedly connected to the output end of the motor 22, the surface of the winding roller 23 is transmission-connected to the surface of the steel cable 3, the bottoms of the two fixed plates 24 are fixedly connected to the left and right parts of the front part of the upper surface of the cliff body 1, the opposite surfaces of the two fixed plates 24 are movably connected to two sliders 27, the opposite surfaces of the two sliders 27 are rotatably connected to two rotating shafts 29, the opposite surfaces of the two rotating shafts 29 are fixedly connected to the rotating shaft 25, and the front and rear parts of the bottoms of the two sliders 27 are fixedly connected to springs 28.

[0028] It should be noted that by starting the motor 22, the winding roller 23 will be driven to rotate counterclockwise, so that the steel cable 3 is released, and the set steel cable 3 is in contact with the rubber pad 26. The set rubber pad 26 can generate a large friction force, so that the rotating shaft 25 rotates along the slider 27, so that the steel cable 3 can be retracted and released more smoothly. At the same time, it will drive the slider 27 to move downward, so that the spring 28 is compressed, which has a certain buffering effect on the steel cable 3, so that the lifting speed of the suspension platform 5 can be kept stable, and at the same time, the steel cable 3 will not contact the corner of the cliff, thereby avoiding the occurrence of friction and improving safety.

[0029] like Figure 2 , Figure 3 As shown, a plurality of rubber pads 26 are fixedly connected to the surface of the rotating shaft 25 in an annular array. The rubber pads 26 are in the shape of semi-cylindrical blocks, and the length of the rubber pads 26 is consistent with the length of the rotating shaft 25 .

[0030] It should be noted that the rubber cushion 26 can generate a greater friction force, so that the retraction and extension of the steel cable 3 is smoother.

[0031] like Figure 4-Figure 6 As shown, the protection mechanism 4 includes four fixed rods 41, the tops of the four fixed rods 41 are fixedly connected to the bottoms of the steel cables 3, the bottoms of the four fixed rods 41 are fixedly connected to the four corners of the top of the suspension platform 5, and three guardrails 42 are fixedly connected to the opposite surfaces of every two fixed rods 41. The three guardrails 42 are respectively located on the left, right and rear sides above the suspension platform 5. Two protective plates 43 are movably connected to the middle position of the two front fixed rods 41, and baffles 44 are fixedly connected to the opposite reverse surfaces of the two protective plates 43.

The right ends of the two sliding rods 401 are fixedly connected to connecting rods 49, and the surfaces of the two sliding rods 401 are movably connected to springs 2 48.

[0032] It should be noted that by pulling the connecting rod 49 forward, the sliding rod 401 will be driven to move along the limiting groove 47, thereby compressing the spring 2 48, and then the two protective plates 43 will be moved to the middle position, so that the two mounting plates 45 are put together, and then the connecting rod 49 is loosened.

[0033] like Figure 6 As shown, four clamping rods 402 are fixedly connected to the left end of the connecting rod 49 , and the lengths of the four clamping rods 402 are all smaller than the length of the sliding rod 401 .

[0034] It should be noted that the length of the sliding rod 401 is greater than the clamping rod 402. When the clamping rod 402 is pulled out, the sliding rod 401 will not be completely detached, thereby achieving a better installation effect.

[0035] like Figure 5 , Figure 6 As shown, four slots 46 are provided on the right side of the left mounting plate 45 , and the surface diameters of the four slots 46 are consistent with the surface diameter of the clamping rod 402 , and the rear end of the clamping rod 402 is in a hemispherical block shape.

[0036] It should be noted that the two protection plates 43 can be installed by sliding the clamping rod 402 into the clamping slot 46 .

[0037] The working principle of the utility model is as follows: by starting the motor 22, the winding roller 23 will be driven to rotate counterclockwise, so that the steel cable 3 is released, and the set steel cable 3 contacts the rubber cushion 26, and the set rubber cushion 26 can generate a large friction force, so that the rotating shaft 25 rotates along the slider 27, so that the steel cable 3 is more smoothly retracted and released, and at the same time, the slider 27 will be driven to move downward, so that the spring 28 is compressed, which has a certain buffering effect on the steel cable 3, so that the lifting speed of the suspension platform 5 can be kept stable, and at the same time, the steel cable 3 will not be touched. Touching the corner of the cliff, friction is avoided and safety is improved. By pulling the connecting rod 49 forward, the sliding rod 401 will be driven to move along the limiting groove 47, thereby compressing the spring 2 48, and then the two protective plates 43 are moved to the middle position, so that the two mounting plates 45 are put together, and then the connecting rod 49 is loosened. Under the action of the spring 2 48, the connecting rod 49 moves to the rear end, and then the clamping rod 402 slides into the clamping groove 46, completing the installation of the two protective plates 43, and cooperating with the three guardrails 42 to achieve a better protection effect.
