Description

Technical Field

[0001] The invention relates to the field of vehicle washing, in particular to a top brush device for vehicle washing. Background Art

[0002] With the development of social economy and the improvement of people's lives, the pace of life has accelerated. Cars have become an indispensable means of transportation in people's lives, and more and more people have their own private cars, which has also driven the rapid development of the car wash industry. However, in recent years, due to the continuous increase in labor costs in my country, manual car washing is not only inefficient but also costly. There is an urgent need for an efficient and fast car washing machine. The existing tunnel car washing device generally includes a side brush for cleaning the top surface of the car body. The entire roof of most vehicles on the market is not of the same degree. The existing car washing and loading generally controls the top brush device to approach the roof for cleaning by detecting the distance and position of the car body. When the detection equipment fails, it is easy to cause damage to the car body; or the brush body is set to float, and the roof is offset against the brush body, and the roof lifts the brush body. In this way, the side body causes different brushing forces on the top brush with different slopes, which is easy to cause damage to the roof. Summary of the invention

[0003] The purpose of the present invention is to provide a top brush device for washing a car to solve the technical problems that the top brush is unreliable and the washing force is unstable, which may easily cause damage to the vehicle.

[0005] Furthermore, the first anti-slip column is located outside the arc formed by the first synchronous wheel and the annular synchronous belt, and the minimum distance between the outer peripheral wall of the anti-slip column and the outer peripheral wall of the annular synchronous belt is less than the thickness of the synchronous teeth on the synchronous belt.

[0006] Furthermore, a first deep groove ball bearing is provided on the first anti-slip column, and an outer ring of the first deep groove ball bearing is connected to an outer peripheral wall of the annular synchronous belt.

[0007] Furthermore, the second anti-slip column is located outside the arc formed by the second synchronous wheel and the annular synchronous belt, and the minimum distance between the outer peripheral wall of the anti-slip column and the outer peripheral wall of the annular synchronous belt is less than the thickness of the synchronous teeth on the synchronous belt.

[0008] Furthermore, a second deep groove ball bearing is provided on the second anti-slip column, and an outer ring of the second deep groove ball bearing is connected to the outer peripheral wall of the annular synchronous belt.

[0009] Furthermore, the guide column is a square column, and the guide column is rotatably connected to the side frame body. Two square rings are provided on the sliding member, and the square rings are sleeved on the guide column. An extension rod perpendicular to the center end of the guide column is provided on the outer wall of one end of the guide column; a telescopic rod is provided on the frame body, and the extension end of the telescopic rod is connected to the extension end of the extension rod.

[0010] Furthermore, the central axis of the brush body is rotatably connected to the sliding member through a bearing seat.

[0011] Furthermore, the driving device includes a driving motor and a transmission rod, the driving motor is installed on any one of the side frames, one end of the transmission rod is installed on one of the side frames, and the other end of the transmission rod is installed on the other side frame, and the driving device drives the transmission rod to rotate; the transmission rod drives the two first synchronous wheels to rotate synchronously through chain drive.

[0012] Furthermore, the driving device drives the transmission rod to rotate through chain transmission.

[0013] Furthermore, it also includes a controller, which is connected to the driving motor and controls the rotation speed of the motor.

[0014] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0015] 1. When the present invention is working, the driving device drives the first synchronous wheel to rotate, and the first synchronous wheel rotates the second synchronous wheel through the annular synchronous belt, thereby driving the brush body to rotate; due to the gravity of the brush body, the brush body is kept at the lower part of the guide column; when washing the car, when the top surface of the vehicle contacts the brush body, the vehicle gives the brush body a torque in the opposite direction to the brush body, causing the rotation speed of the brush body to decrease, and the side of the annular synchronous belt that moves upward has a tendency to make the brush body move upward, and then due to the gravity of the brush body, the brush body has a tendency to move downward, and the upward and downward movements tend to be The forces offset each other, so that the height position of the brush body remains unchanged; the vehicle roof and the brush body are constantly approaching, so that the torque acting on the brush body becomes larger, causing the rotation speed of the brush body to decrease again, and the upward movement trend of the brush body is greater than the downward movement trend caused by gravity. The brush body moves upward, and the brush body is raised along the guide column position; after the brush body position is raised, the distance from the vehicle roof becomes larger, the torque becomes smaller, and the rotation speed of the brush body decreases again, and repeats, and finally the upward movement trend of the brush body and the downward movement trend caused by gravity offset each other, and the brush body keeps the distance from the roof unchanged, maintaining the washing force. When the brush body rises, the side of the annular synchronous belt that is descending will relax, but due to the use of the first anti-slip column and the second anti-slip column, the annular synchronous belt will not fall off the first synchronous wheel and the second synchronous wheel, ensuring the normal operation of the annular synchronous belt. Based on the above, the brush body of the present invention can maintain a relatively constant washing force, which can prevent damage to the top surface of the vehicle roof. At the same time, when the brush body is subjected to a large force, it can be raised autonomously, which can prevent the collision between the vehicle and the brush body and prevent accidents during vehicle cleaning.

[0016] 2. The present invention provides deep groove ball bearings on the first anti-slip column and the second anti-slip column, so that when the annular synchronous belt contacts the first anti-slip column and the second anti-slip column, sliding is changed into rolling, thereby reducing the friction of the annular synchronous belt, reducing the probability of the annular synchronous belt being stuck, increasing the reliability of the device, and extending the service life of the annular synchronous belt.

[0017] 3. The present invention sets the guide column into a rotatable square column structure, and pushes the telescopic rod to make the outer wall of the guide column connect with the inner wall of the square ring, so that friction is formed between the two, so that the brush body can be fixed at a relatively high position, which is convenient for use when the brush body needs to be positioned.

[0018] 4. The present invention is provided with a controller, and the rotation speed of the annular synchronous belt can be directly increased through the controller, so that the annular synchronous belt lifts the brush body, which is convenient for use when needed.

In this embodiment, the second anti-slip column f21 is located directly below the second synchronous wheel f42. A second deep groove ball bearing f22 is provided on the second anti-slip column f21. The outer ring of the second deep groove ball bearing f22 is connected to the outer peripheral wall of the annular synchronous belt f43.

[0031] In this embodiment, the guide post f11 is a square column, and the guide post f11 is rotatably connected to the side frame body f1. Two square rings f23 are arranged on the sliding member f2, and the square ring f23 is sleeved on the guide post f11. The outer wall of one end of the guide post f11 is provided with an extension rod f15 perpendicular to the central end of the guide post f11; a telescopic rod f14 is arranged on the frame body, and the extension end of the telescopic rod f14 is connected to the extension end of the extension rod f15. The central axis of the brush body f3 is rotatably connected to the sliding member f2 through a bearing seat f24. The driving device f5 includes a driving motor f51 and a transmission rod f52. The driving motor f51 is installed on either side frame body f1, one end of the transmission rod f52 is installed on one side frame body f1, and the other end of the transmission rod f52 is installed on the other side frame body f1.
