Description
Technical Field
[0001] This utility model relates to the technical field of high-speed train maintenance equipment, specifically an automatic cleaning and maintenance device for the pantograph of a high-speed train. Background Technology
[0002] Cleaning and maintenance of the pantograph on high-speed trains requires a combination of routine inspections and specialized maintenance. The following are key steps and precautions: Use a soft cloth or brush with a neutral detergent to wipe the surface and contact points of the pantograph, focusing on removing dust, grease, and other impurities. Avoid using strong corrosive solvents or excessive water to prevent damage to electrical components. Currently, dust removal is mainly done manually with cloths, but this cleaning method is neither efficient nor effective.
[0003] A search revealed a Chinese patent, CN214638486U, which describes an automatic decontamination and dust removal device for high-speed rail pantograph insulators. Specifically, it provides a device that is simple in structure, easy to carry, simple to operate, and can thoroughly decontaminate insulators. It can be customized according to the shape of the insulator to maximize cleaning effect and efficiency, while reducing the intensity of manual labor.
[0004] However, the above technical solutions are customized according to the shape of the insulator, and can only clean pantograph insulators of the same shape and size at one time. They cannot adapt to pantograph insulators of different diameters and shapes, thus failing to fully clean the surface of the pantograph insulators, resulting in poor cleaning effect and insufficient practicality. Utility Model Content
[0005] This utility model provides an automatic cleaning and maintenance device for pantographs of high-speed trains, aiming to solve the problems mentioned in the background art, which are that the existing technology is customized according to the shape of the insulator, and can only clean pantograph insulators of the same shape and size at one time. It cannot adapt to pantograph insulators of different diameters and shapes, thus failing to fully clean the surface of the pantograph insulators, resulting in poor cleaning effect and insufficient practicality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning and maintenance device for a high-speed train pantograph, comprising a cleaning cover with a circular opening at the top, a support frame fixedly installed on the top of the cleaning cover, a first motor fixedly installed on the top of the support frame, a telescopic cylinder fixedly installed on the output shaft of the first motor, and a cleaning component fixedly installed at the end of the telescopic cylinder; the cleaning component comprises a boom fixedly connected to the output end of the telescopic cylinder, a U-shaped frame fixedly connected to the bottom of the boom, a rotating shaft rotatably connected between the inner walls of the two sides of the U-shaped frame, a brush fixedly installed on the outer wall of the rotating shaft, a first pulley fixedly installed on the top of the rotating shaft, a second motor fixedly installed on one side of the top of the U-shaped frame, a second pulley fixedly installed on the output shaft of the second motor, and a belt sleeved between the first pulley and the second pulley; an elastic sliding structure is fixedly installed on the side of the U-shaped frame away from the brush, and an annular groove adapted to the elastic sliding structure is formed along the circumferential direction on the inner wall of the cleaning cover.
[0007] During use, the cleaning component at the end of the telescopic cylinder is adjusted according to the size and shape of the insulator, so that the U-shaped frame is close to the insulator, allowing the brush to fully contact the outer surface of the insulator. This adapts to insulators of different sizes and shapes, thereby improving the cleaning effect. Then, the second motor is started, which drives the second pulley to rotate. The second pulley drives the first pulley and the rotating shaft to rotate via a belt. The rotating shaft then drives the first pulley to rotate. At the same time, the elastic sliding structure and the annular groove work together to ensure that the U-shaped frame remains stable during rotation.
[0008] Preferably, the elastic sliding structure includes a fixed block fixedly connected to the outside of the U-shaped frame, a sliding block slidably connected to the inner wall of the annular groove, and a spring rod fixedly connected between the fixed block and the sliding block.
[0009] Preferably, a support column is fixedly installed at the bottom of the U-shaped frame, and a ball bearing that contacts the inner wall of the U-shaped frame is slidably embedded at the bottom of the support column.
[0010] Preferably, the support frame includes a support rod fixedly connected to the top of the cleaning cover and a mounting plate fixedly installed on the top of the support rod.
[0011] Preferably, the inner axial part of the cleaning cover is used to accommodate the insulator.
[0012] Preferably, the bottom of the cleaning cover is fixedly equipped with a support foot, and the bottom of the support foot is fixedly equipped with a rubber anti-slip pad.
[0013] The automatic cleaning and maintenance device for the pantograph of this high-speed train is simple in structure and easy to use. According to the size and shape of the insulator, the cleaning component at the end of the telescopic cylinder is adjusted so that the U-shaped frame is close to the insulator, and the brush makes full contact with the outer surface of the insulator. This adapts to insulators of different sizes and shapes, thereby improving the cleaning effect. Then, the second motor is started, which drives the second pulley to rotate. The second pulley drives the first pulley and the rotating shaft to rotate through the belt. The rotating shaft then drives the first pulley to rotate. At the same time, the elastic sliding structure and the annular groove ensure that the U-shaped frame remains stable during rotation. Attached Figure Description
