Description

Technical Field

[0001] The utility model relates to the technical field of bridge stay cables, in particular to a cleaning device for bridge stay cables. Background Art

[0002] A cable-stayed bridge is a bridge that uses multiple cables to hang the bridge deck on the tower. Cable cleaning is a work of bridge maintenance. At present, there are two main ways to clean the cable: basket cleaning and climbing equipment cleaning. Basket cleaning is to lift the construction basket by a crane, and the staff stand in the basket to clean the cable. This method has low construction efficiency, large workload, high equipment requirements, and the crane needs to occupy at least two lanes, so that the bridge needs to be temporarily blocked, which has a great impact on traffic. Climbing equipment refers to equipment that is held on the cable and driven by climbing wheels to climb along the cable for cleaning. Since this equipment is provided with climbing force by the climbing wheels holding the cable, and the friction coefficient of the cable surface is small, the climbing force that can be provided is limited. In particular, when the cable surface is wet, there is an adhered water layer, water mist, sand and dust, ice, and stubborn debris, this type of equipment often slips or even slides. Due to its limited climbing force, the corresponding cleaning ability is also limited, and stubborn stains cannot be effectively removed. Utility Model Content

[0026] Furthermore, the clamping assembly includes two movable plates 301, and the two movable plates 301 are connected to the fixed frame 104 through the movable shafts 302 on their sides. A movable block 303 is connected to the upper side of the movable plate 301 opposite to the movable shaft 302, and a spring 304 is connected to the side of the movable block 303. A second fixed block 305 is connected to the side of the spring 304 opposite to the movable block 303. An upper connecting block 306 is connected to the side of the movable plate 301 opposite to the movable block 303. A fixed frame 307 is arranged in the fixed frame 104 below the upper connecting block 306, and a sponge cover 308 is arranged on the surface of the upper connecting block 306 and the fixed frame 307 on the side close to the fixed frame 307.

[0027] Furthermore, the cleaning component includes two first transmission shafts 401 located inside the connecting frame 101, and both ends of the first transmission shafts 401 are movably connected to the sides of the connecting frame 101, and one end of the first transmission shaft 401 passes through the connecting frame 101 and is connected to the power output shaft end of the mobile power supply inside the fixed frame 104, and a brush 402 coaxial with the first transmission shaft 401 is arranged on the periphery of the first transmission shaft 401, and a cleaning roller 403 is arranged on the side of the brush 402 on the periphery of the first transmission shaft 401, and the cleaning roller 403 is coaxial with the first transmission shaft 401.

[0029] The working principle of the utility model is specifically described as follows:

[0030] In this design, when the bridge cable needs to be cleaned, the fixing plate 501 is first fixed to the ground through the suction cup 504, and then the ropes wound on the two winding rollers 503 are passed through the two U-shaped blocks 502 respectively;

[0031] The pull rope passing through the U-shaped block 502 continues to pass through the buckle 204 on the side away from the fixed block 202, then passes through the buckle 204 on the side close to the fixed block 202 and is wrapped around the buckle 204 once, then extends downward, is wrapped around the pulley 506 on the trolley 505, and extends upward from one side of the pulley 506. Finally, the end of the pull rope opposite to the winding roller 503 is tied to the connecting frame 201 on the side of the fixed block 202.

[0032] Then, the movable block 303 above the movable plate 301 is moved. After the movable block 303 moves, it drives the movable plate 301 connected thereto to rotate around the central axis of the movable shaft 302, and the two closed movable plates 301 are opened. After the movable plates 301 are opened, the main body of the moving device is moved, and the inclined cable is placed on the fixed frame 307. Then, the movable block 303 squeezed by the spring 304 is released. The movable block 303 is reset to the initial position under the elastic force of the spring 304, and the inclined cable is stuck between the fixed frame 307 and the upper connecting block 306.

[0033] Then the trolley 505 is driven. After the trolley 505 moves, it drives the main body of the device upward through two tensioning ropes located on the side of the device. During this process, the pull rope can provide sufficient climbing force for the device. During the movement of the device, the mobile power supply in the fixed frame 104 drives the first transmission shaft 401 connected to it to rotate. After the first transmission shaft 401 rotates, it drives the brush 402 and the cleaning roller 403 on its periphery to rotate, thereby cleaning the stubborn stains on the surface of the inclined cable.
