Description

Technical Field

[0001] This utility model relates to the technical field of train cleaning equipment, and in particular to a swing-out device for a train side washing mechanism. Background Technology

[0002] With the development of my country's economy, cities are facing increasing traffic pressure, and more and more cities are vigorously developing subways. Subways are a form of rail transport, a city rail transit system that primarily operates underground. Because they are built underground, subways save urban land, avoid traffic congestion on roads, reduce noise and interference, save energy, and reduce pollution.

[0003] After prolonged operation, trains require cleaning, especially the sides. Current methods typically involve cleaning the sides of trains using brushes parallel to the track. This method uses side-cleaning brushes to keep the train clean. During cleaning, the vertical brushes need a swing-out device to extend them to the cleaning position. A swing-out locking and positioning device completes the swing-out, locking, and positioning functions. Swinging is achieved by a swing-out cylinder driving a bending plate, causing the brush holder to rotate at a certain angle. Positioning is achieved by adjusting the distance between positioning blocks on the bracket of the swing-out locking and positioning device, thus adjusting the swing-out angle.

[0004] The above-mentioned defects are as follows: in the existing swing-out device, the locking device and the positioning device are located below the column assembly, which makes it easy for the swing to collide and fall off, posing a safety hazard. Furthermore, the top arc brush assembly needs to be locked when it is not working. For safety reasons, the top arc brush assembly cannot be arbitrarily swinged out. Therefore, a swing-out device for the train side washing mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a swing-out device for a train side washing mechanism, which aims to improve the problem that in the prior art, the locking device and positioning device are both located below the column assembly, which leads to the safety hazard of collision and detachment caused by random swinging.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a swing-out device for a train side washing mechanism, comprising a locking and positioning cylinder, a locking tongue, a stop block, a positioning stop block, a positioning stop block locking nut, a brush holder swing-out locking and positioning device bracket, and a swing-out driving cylinder. The swing-out driving cylinder fixing pin is fixed on the brush holder swing-out locking and positioning device bracket, and the swing-out driving cylinder is fixed by the swing-out driving cylinder fixing pin. The locking and positioning cylinder is fixed on a locking and positioning cylinder fixing seat, and the locking and positioning cylinder fixing seat is connected to the brush holder swing-out locking and positioning device bracket. The swing-out driving cylinder rod joint connecting pin is connected to the swing-out driving cylinder piston rod connecting block. The locking tongue is connected to the locking and positioning cylinder, the stop block is connected to the brush holder swing-out locking and positioning device bracket, the positioning stop block is connected to the stop block, and the positioning stop block is fixed by the positioning stop block locking nut. The brush holder swing-out fixing bending plate connecting block is connected to the brush holder swing-out fixing bending plate.

[0007] As a further description of the above technical solution: the brush holder swing-out locking and positioning device bracket and the brush holder swing-out fixing bend plate are respectively fixed on the column assembly and the brush holder on the upright brush. The brush holder swing-out locking and positioning device bracket is fixed on the column assembly, and the brush holder swing-out fixing bend plate is fixed on the brush holder. The swing-out driving cylinder is fixed by the swing-out driving cylinder fixing pin. The swing-out driving cylinder drives the brush holder swing-out fixing bend plate connecting block to move the brush holder swing-out fixing bend plate forward, causing the column assembly to rotate by an angle, so that the brush group swings out by an angle.

[0008] As a further description of the above technical solution: the locking and positioning cylinder is fixed to the locking and positioning cylinder fixing seat, the locking and positioning cylinder fixing seat is connected to the brush holder swing-out locking and positioning device bracket, the locking and positioning cylinder is connected to the locking tongue, the locking tongue blocks the brush holder swing-out fixing plate, and after unlocking, the brush holder swing-out fixing plate moves under the drive of the swing-out driving cylinder.

[0009] As a further description of the above technical solution: the brush holder swings out and the fixed bending plate moves to the positioning block and then stops moving. The positioning block is connected to the bracket of the brush holder swing-out locking positioning device. The positioning block is connected to the upper block fixing shaft and the lower block fixing shaft respectively. The positioning block rotates around the upper block fixing shaft and the lower block fixing shaft. The block is connected to the positioning block, and the length of the positioning block can be adjusted. The positioning block is fixed with the positioning block locking nut.

[0010] As a further description of the above technical solution: the brush holder swing-out fixed bending plate is connected to the brush holder swing-out fixed bending plate connecting block, the brush holder swing-out fixed bending plate connecting block is connected to the swing-out drive cylinder piston rod connecting block, the swing-out drive cylinder piston rod connecting block is connected to the swing-out drive cylinder, the swing-out drive cylinder pushes the swing-out drive cylinder piston rod connecting block forward and then pushes the brush holder swing-out fixed bending plate connecting block, and finally pushes the brush holder swing-out fixed bending plate to rotate, thereby causing the brush holder to rotate and swing out the top arc brush assembly.

[0011] As a further description of the above technical solution: the bracket of the brush holder swing-out locking positioning device is connected to the side cover of the brush holder swing-out locking positioning device, and is fixed with the screws of the side cover of the brush holder swing-out locking positioning device.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the brush group can automatically lock itself after the work is completed, so that the brush group cannot be arbitrarily moved out. Only after a command is issued can the locking mechanism be activated to release the lock and the brush group can be moved out. This improves the problem that when the top arc brush group assembly is not working, it can be arbitrarily moved out, which can easily cause shaking, loosening or collision and certain safety hazards. In addition, the original locking device and positioning device are located below the column assembly, which makes inspection and maintenance inconvenient.

[0014] 2. In this utility model, the brush holder drive mechanism is equipped with a return automatic locking mechanism, forming a swing-out, locking, and positioning function within a single device. The return automatic locking mechanism is added to the original brush holder drive mechanism. The swing-out locking and positioning device consists of two mechanisms: one for swing-out positioning, and the other for adjusting the swing-out angle and distance simultaneously, thus improving the problem of unsatisfactory adaptability of single angles and distances.
