Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment, and particularly relates to a vehicle cleaning device. Background Art

[0002] During the operation of rail transit vehicles such as railway, subway locomotives and light rail locomotives, due to the intense impact and friction between the end faces and the air, a large amount of dirt and dust will adhere to the vehicle surface. According to the daily maintenance requirements of the vehicle, the rail vehicles need to be cleaned regularly.

[0003] In the existing rail vehicle cleaning device, most of the brush groups are installed on a rotatable cantilever bracket. The cantilever bracket rotates by a certain angle to make the brush group contact with the surface of the rail vehicle, and the contact degree between the brush group and the surface of the rail vehicle can also be controlled by controlling the rotation angle of the cantilever bracket to ensure the cleaning effect. However, there is a certain angle between the cantilever bracket and the extension direction of the rail vehicle, so that the contact degree between the rail vehicle and the brush group will be different when the rail vehicle enters and exits the cleaning device. To solve this problem, most of the existing cleaning devices are provided with two groups. One group is used to clean the rail vehicle when it enters the cleaning device, and the other group is used to clean the rail vehicle when it exits the cleaning device. However, this correspondingly increases the floor area of the cleaning device and the manufacturing cost. Moreover, due to the certain angle between the rail vehicle and the cantilever bracket, the cantilever bracket is easily broken when the rail vehicle enters and exits the cleaning device, which poses a certain safety hazard.

[0039] The technical solution of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

[0040] As Figures 1 to 5 shown, this embodiment provides a vehicle washing device, which reduces the production cost and floor area of the vehicle washing device and also ensures the safety during the washing process.

[0041] Referring to Figure 1 and Figure 2 , the vehicle washing device includes a support frame 1, a brush assembly 2, a first driving member 3, and a second driving member 4. The brush assembly 2 is movably arranged on the support frame 1, and the brush assembly 2 is configured to wash the surface of the rail vehicle; both the first driving member 3 and the second driving member 4 are arranged on the support frame 1, and the output ends of the first driving member 3 and the second driving member 4 are both connected to the brush assembly 2. The first driving member 3 is used to drive the brush assembly 2 to rotate forward and backward, and the second driving member 4 is used to drive the brush assembly 2 to move in a first direction ( Figure 1 the X direction in Figure 1 ), and the first direction is perpendicular to the moving direction (

[0042] the Y direction in

[0043] Figure 1 ) of the rail vehicle.

[0042] For the vehicle washing device provided in this embodiment, when the rail vehicle drives towards the vehicle washing device, the first driving member 3 drives the brush assembly 2 to rotate forward, and when the rail vehicle drives away from the vehicle washing device, the first driving member 3 drives the brush assembly 2 to rotate backward. That is, only one brush assembly 2 can be used to wash the rail vehicle in two directions, reducing the production cost and floor area of the vehicle washing device. The brush assembly 2 can only move in the first direction under the drive of the second driving member 4 to adjust the distance between the brush assembly 2 and the rail vehicle, so that when the rail vehicle drives towards and away from the vehicle washing device, the brush assembly 2 can always be perpendicular to the moving direction of the rail vehicle. Therefore, no matter whether the brush assembly 2 rotates forward or backward, the contact degree between the brush assembly 2 and the rail vehicle will not change, ensuring the washing effect on the rail vehicle. In addition, compared with the cantilever structure, the frame structure is more stable, so that the brush assembly 2 arranged on the support frame 1 is not easily damaged by the rail vehicle during washing, ensuring the safety during the washing process.

[0043] In this embodiment, the normal rotation of the brush assembly 2 is a clockwise rotation about its axis, and the reverse rotation of the brush assembly 2 is a counterclockwise rotation about its axis; in other embodiments, the normal rotation of the brush assembly 2 is a counterclockwise rotation about its axis, and the reverse rotation of the brush assembly 2 is a clockwise rotation about its axis.

[0044] Optionally, referring to Figure 1 , the vehicle washing device further includes a first connecting shaft 5 and a moving seat 6.

Specifically, the second driving member 4 drives the first connecting shaft 5 to rotate, and the first connecting shaft 5 drives the moving seat 6 to move along its axis through the thread. The movement of the moving seat 6 can drive the brush assembly 2 to move. Among them, the threaded connection between the first connecting shaft 5 and the moving seat 6 enables the moving seat 6 to move stably along the first direction, so as to stably drive the brush assembly 2 to move and ensure the safety of the cleaning process; moreover, the threaded connection also facilitates the precise control of the position of the moving seat 6, so that the brush assembly 2 can maintain an appropriate contact amount with the surface of the rail vehicle, preventing the contact amount from being too large or too small from affecting the cleaning effect.

[0045] In this embodiment, the first connecting shaft 5 is provided with an external thread, and the moving seat 6 is provided with a threaded through hole extending along the first direction, and the threaded through hole is in threaded cooperation with the external thread.

[0046] Exemplarily, the second driving member 4 is a motor, the first connecting shaft 5 is a lead screw, and the moving seat 6 is a nut. The motor can drive the first connecting shaft 5 to rotate clockwise or counterclockwise about its axis to drive the moving seat 6 to move positively or negatively along the first direction.

[0047] In an alternative embodiment, only one first connecting shaft 5 and one moving seat 6 are provided. The brush assembly 2 is fixedly connected to the moving seat 6, and the output end of the second driving member 4 is directly connected to the first connecting shaft 5. When the first connecting shaft 5 rotates, the moving seat 6 directly drives the brush assembly 2 to move.

[0048] In another alternative embodiment, referring to Figure 1 , a plurality of first connecting shafts 5 and a plurality of moving seats 6 are provided. The plurality of moving seats 6 correspond to the plurality of first connecting shafts 5 one by one.

Both ends of the brush assembly 2 are respectively fixed to any two adjacent connecting members 8 along the third direction. The first direction, the second direction, and the third direction are perpendicular to each other pairwise. The second driving member 4 can drive each first connecting shaft 5 to rotate simultaneously through the transmission assembly 7, and then drive a plurality of moving seats 6 to move simultaneously, so that both ends of the connecting member 8 can move the same distance in the same direction, and the distances moved by each connecting member 8 are also the same. Thus, both ends of the brush assembly 2 can also move the same distance in the same direction, improving the stability and accuracy of the movement of the brush assembly 2. With such a setting, a plurality of brush assemblies 2 can also be provided on the vehicle washing device to enable a plurality of brush assemblies 2 to wash the rail vehicle simultaneously, improving the washing efficiency.

[0049] Exemplarily, the connecting member 8 is made of an I-beam, which has high rigidity, is not easily deformed, and is easy to connect with the brush assembly 2. In this embodiment, the brush assembly 2 is located at the middle position of the connecting member 8 along the second direction. With such a setting, the connecting member 8 is evenly stressed, and the second driving member 4 can more accurately control the position of the brush assembly 2 through the moving seat 6 and the connecting member 8.

[0050] Further, referring to Figure 1 , the transmission assembly 7 includes a plurality of steering gears 71, a plurality of second connecting shafts 72, and a plurality of third connecting shafts 73.

Any two adjacent steering gears 71 along the second direction can be connected by the second connecting shaft 72, and any two adjacent steering gears 71 along the third direction can be connected by the third connecting shaft 73. The output end of the second driving member 4 can be selectively connected to any one of the steering gears 71. The second driving member 4 can drive the corresponding first connecting shaft 5 to rotate through the steering gear 71 connected thereto, and drive the corresponding second connecting shaft 72 and / or the corresponding third connecting shaft 73 connected thereto to drive the first connecting shafts 5 that are not connected to the same steering gear 71 as the second driving member 4 to rotate. The setting of the steering gear 71 can change the direction of power transmission to adapt to the plurality of first connecting shafts 5 arranged in a matrix. The settings of the second connecting shaft 72 and the third connecting shaft 73 also enable the second driving member 4 to be connected to all the first connecting shafts 5 to drive all the first connecting shafts 5 to rotate simultaneously.

[0051] Referring to Figure 1, in this embodiment, when there is a set of brush assemblies 2, there are four first connecting shafts 5, moving seats 6 and steering gears 71, two second connecting shafts 72, one third connecting shaft 73, and two connecting members 8. Among them, referring to Figure 1 in the orientation shown, there are two layers arranged along the third direction.

[0052] In other embodiments, there is a set of brush assemblies 2, there is one second connecting shaft 72, and there are two third connecting shafts 73. Referring to Figure 1 in the orientation shown, there are two layers arranged along the third direction. Two first connecting shafts 5 are arranged at intervals along the second direction in each layer.

The second connecting shaft 72 in the lower layer drives the first connecting shaft 5 in the lower right corner and the third connecting shaft 73 on the right side to rotate simultaneously through the steering gear 71 in the lower right corner. The third connecting shaft 73 on the left side drives the first connecting shaft 5 in the upper left corner to rotate through the steering gear 71 in the upper left corner, so that the four moving seats 6 can move simultaneously, so that both ends of the brush assembly 2 can move simultaneously.

[0053] In some embodiments, the second driving member 4 is connected to the steering gear 71 at other positions.

[0054] In some embodiments, referring to Figure 1 and Figure 3When the brush assembly 2 is provided with multiple groups along the second direction and / or the third direction, the first connecting shaft 5, the movable seat 6, the diverter 71, the second connecting shaft 72 and the third connecting shaft 73 are provided in plurality, and the number and position of the above-mentioned components are determined according to the arrangement and quantity of the brush assembly 2, as long as the second driving member 4 can drive multiple first connecting shafts 5 to rotate simultaneously through the diverter 71, the second connecting shaft 72 and the third connecting shaft 73.

[0055] Exemplarily, the second connecting shaft 72 and the third connecting shaft 73 are both screw rods. In other embodiments, the second connecting shaft 72 and the third connecting shaft 73 may also be rotating shafts with smooth outer surfaces.

[0056] See also Figure 1 In this embodiment, the support frame 1 includes a plurality of support columns 11, a plurality of first support beams 12 and a plurality of second support beams 13. The support columns 11 extend along a third direction, the first support beams 12 extend along a first direction, and the second support beams 13 extend along a second direction. The plurality of first support beams 12 correspond one-to-one to the plurality of first connecting shafts 5. The plurality of support columns 11, the plurality of first support beams 12 and the plurality of second support beams 13 form a frame structure to stably support the brush assembly 2 and ensure safety during the cleaning process.

[0057] Exemplarily, the first support beam 12 , the second support beam 13 and the support column 11 are all made of I-beams, and the first support beam 12 , the second support beam 13 and the support column 11 can be connected by bolts or welding.

[0058] Further, see Figure 1 A first ear plate 121 is provided on the first support beam 12, and the first ear plate 121 is located on the side of the movable seat 6 away from the second driving member 4. One end of the first connecting shaft 5 is passed through the first ear plate 121 and rotatably cooperates with the first ear plate 121 to connect the first connecting shaft 5 with the support frame 1, so that the first connecting shaft 5 can only rotate but not move on the support frame 1.

[0059] Exemplarily, the first ear plate 121 is a vertical bearing, and the vertical bearing is fixed to the supporting frame 1 by bolts.

[0060] Optionally, see Figure 1 and Figure 4 The movable seat 6 is provided with a pulley 61, and the support frame 1 is provided with a pulley groove 122, and the pulley groove 122 is slidably matched with the pulley 61. Such an arrangement can reduce the friction between the support frame 1 and the movable seat 6, and prevent the support frame 1 from affecting the movement of the movable seat 6.

[0061] See also Figure 1 and Figure 4, in this embodiment, the first support beam 12 is an I-beam, and the pulley groove 122 is formed by enclosing the flange and web of the I-beam. Two pulley grooves 122 symmetrically arranged along the second direction are formed on each first support beam 12; a U-shaped pulley seat 62 fixedly connected to the moving seat 6 is arranged below the moving seat 6. An installation groove is formed on the U-shaped pulley seat 62. A plurality of pulleys 61 are provided, and the plurality of pulleys 61 are symmetrically fixed to two side arms of the pulley seat 62 along the second direction and are located in the installation groove, and the pulleys 61 are in sliding fit with the corresponding pulley grooves 122. The arrangement of the plurality of pulleys 61 facilitates the movement of the moving seat 6 on the support frame 1 more, and the symmetrical arrangement of the plurality of pulleys 61 enables the moving seat 6 to move more stably on the support frame 1; the arrangement of the pulley seat 62 can facilitate the installation of a plurality of pulleys 61 on the moving seat 6 at the same time.

[0062] Exemplarily, referring to Figure 1 and Figure 4 , the connecting member 8 is connected to the moving seat 6 through the pulley seat 62. Four pulleys 61 are provided, and every two pulleys 61 are in sliding fit with a pulley groove 122, and the two pulleys 61 in sliding fit with a pulley groove 122 are arranged at intervals along the first direction.

[0063] Exemplarily, referring to Figure 1 and Figure 4 , the pulley 61 adopts a tapered wheel, which has high transmission efficiency and is more convenient for the moving seat 6 to move on the support frame 1.

[0064] Furthermore, referring to Figure 1 and Figure 4 , the moving seat 6 is a nut, and the connecting member 8 is fixedly connected to the corresponding pulley seat 62. Because the pulley seat 62 has a large size, compared with directly connecting to the nut, the connection between the connecting member 8 and the pulley seat 62 is more convenient and firm.

[0065] Optionally, the vehicle washing device further includes a telescopic waterproof cover. The waterproof cover is sleeved outside the first connecting shaft 5 in a sealed manner. One end of the waterproof cover is fixed to the moving seat 6, and the other end is fixed to the support frame 1. When the moving seat 6 moves, it can drive the waterproof cover to stretch. The waterproof cover can protect the first connecting shaft 5 during the process of washing the rail vehicle, prevent water and cleaning liquid from entering between the first connecting shaft 5 and the moving seat 6, and avoid rusting of the first connecting shaft 5, which affects the movement of the moving seat 6.

[0066] Furthermore, referring to Figure 1 , a second ear plate 123 is further arranged on the first support beam 12. The second ear plate 123 is located on the side of the moving seat 6 facing the corresponding steering gear 71. One end of the first connecting shaft 5 passes through the second ear plate 123 and is connected to the corresponding steering gear 71, and the first connecting shaft 5 is in rotational fit with the second ear plate 123. The waterproof cover (not shown in the figure) is connected to the first support beam 12 through the first ear plate 121 and the second ear plate 123.

[0067] Exemplarily, the waterproof cover is a bellows-type protective cover, which is fixed to the first ear plate 121 or the second ear plate 123 by screws.

[0068] Optionally, referring to Figure 1 and Figure 2 , the brush assembly 2 includes a rotatable brush shaft 21 and a brush 22 sleeved on the brush shaft 21. The output end of the first driving member 3 is connected to the brush shaft 21 and is used to drive the brush shaft 21 to rotate forward and backward, so that the brush 22 rotates.

[0069] Exemplarily, the first driving member 3 is a motor. Referring to Figure 1 and Figure 2 , a speed reducer 31 is further arranged between the motor and the brush shaft 21. The output end of the motor is connected to the brush shaft 21 through the speed reducer 31. When the motor drives the brush shaft 21 to rotate, the speed reducer 31 can not only change the direction of power transmission, but also reduce the speed of the motor and increase the torque output by the motor, which is more convenient to drive the brush shaft 21 to drive the brush 22 to rotate.

[0070] Optionally, the vehicle washing device further includes an image recognizer and a control member arranged on the support frame 1. The image recognizer is located at the vehicle inlet end of the vehicle washing device and is configured to collect the dimensions of the rail vehicle. The control member stores the initial position of the brush assembly 2 when preset rail vehicles are washed. At the initial position, the brush assembly 2 contacts the preset rail vehicle with a preset distance. The control member is communicatively connected to the image recognizer, and the control member can obtain the washing position of the brush assembly 2 when washing the rail vehicle. At the washing position, the brush assembly 2 contacts the rail vehicle with a preset distance. Wherein, the preset rail vehicle is a kind of rail vehicle that has been put into production and use, and the staff can obtain the dimensions of the existing rail vehicle; the preset distance is the contact amount between the brush assembly and the preset rail vehicle or the rail vehicle during washing. When washing the vehicle according to the preset distance, the preset rail vehicle and the rail vehicle can be washed clean without damaging the surfaces of the preset rail vehicle and the rail vehicle. The arrangement of the image recognizer and the control member enables the vehicle washing device to adaptively adjust the position of the brush assembly 2 according to the dimensions of the rail vehicle to be washed, so that the brush assembly 2 can maintain a proper contact degree when washing the rail vehicle, ensuring the washing effect of the rail vehicle.

[0071] Specifically, the image recognizer can transmit the collected dimensions of the rail vehicle to the control member. The control member can obtain the difference in dimensions between the rail vehicle and the preset rail vehicle by comparing the dimensions of the rail vehicle and the preset rail vehicle. Furthermore, the control member can obtain the washing position of the brush assembly 2 by adding and subtracting the coordinates of the brush assembly 2 at the initial position and the above difference, that is, the absolute value of the difference in dimensions between the rail vehicle and the preset rail vehicle is the difference in coordinates between the initial position and the washing position.
