DETAILED DESCRIPTION

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] Example 1:

[0022] refer to Figure 1-5 A tunnel car washing machine includes a truss 1, a gantry 2 and a cross frame 3 are slidably connected to the interior of the truss 1, the gantry 2 and the cross frame 3 are both equipped with a transverse driving mechanism 4, and a beam sensor is installed on the truss 1;

[0023] The transverse drive mechanism 4 includes two fixed frames 41. Both ends of the gantry 2 are bolted to the fixed frames 41. A first motor 42 is installed on one side of the fixed frame 41. The output end of the first motor 42 is sleeved with a rotating rod 43. The other end of the rotating rod 43 is rotatably connected to the fixed frame 41. Both ends of the rotating rod 43 are fixedly sleeved with driving wheels 44. A driven wheel 45 and a support wheel 46 are rotatably connected to the fixed frame 41 respectively.

[0024] A lifting drive mechanism 5 is installed on the top of the gantry 2, and a horizontal brush mechanism 6 is slidably connected to the inner side of the gantry 2. The lifting drive mechanism 5 drives the horizontal brush mechanism 6 to rise and fall.

[0025] The first motor 42 can drive the rotating rod 43 to rotate, and the driving wheel 44 is fixedly connected with the wheel shaft inside, and the first motor 42 can drive the rotating rod 43 to rotate. The driving wheel 44 is fixedly connected with the wheel shaft, and the first motor 42 can drive the rotating rod 43 to rotate. The driving wheel 44 and the driven wheel 45 are fixedly sleeved with the rotating rod 43 at one end of the wheel shaft. The rotating rod 43 drives the driving wheels 44 at both ends to rotate. The surfaces of the driving wheel 44 and the driven wheel 45 abut against the truss 1 track, and the supporting wheel 46 abuts against the side of the truss 1 track. When the driving wheel 44 rotates, the driven wheel 45 and the supporting wheel 46 cooperate to move on the truss 1 track, and can drive the fixed frame 41 to move, so that the transverse driving mechanism 4 can drive the gantry 2 and the cross frame 3 to move on the truss 1, and can move the horizontal brush mechanism 6 horizontally. The conveying device is installed on the ground inside the truss 1. The gantry 2 and the horizontal brush mechanism 6 are first located at the origin, and the detection of whether a vehicle enters is detected by the corresponding sensor on the column of the truss 1. When a vehicle arrives, the horizontal brush mechanism 6 starts to rotate and spray water. The vehicle moves through the transmission device below, and the speed is controllable or constant. When the vehicle moves forward, the front of the vehicle hits the horizontal rolling brush 61, which causes the torque parameter of the third motor 63 to change. The change in the torque parameter of the third motor 63 causes the lifting drive mechanism 5 to start lifting and lowering. When the torque parameter is higher than the preset safety value range, it rises, and when the torque parameter is lower than the preset safety value range, it falls. When it rises and falls to the preset safety value range, it performs normal work. The horizontal rolling brush 61 also judges the position of the vehicle by the corresponding sensor when chasing the rear of the vehicle. The horizontal rolling brush 61 drops to the specified position and moves forward to chase the rear of the vehicle. When the torque parameter of the third motor 63 is higher than the preset safety value range, it retreats. When the torque parameter of the third motor 63 is lower than the preset safety value range, it leans forward. When it leans forward and retreats to the preset safety value range, it performs normal work and catches up to the end point of the horizontal movement of the horizontal rolling brush 61. Then the horizontal movement drive mechanism 4 drives the horizontal rolling brush 61 back to the starting point to wait for the next vehicle.

[0026] refer to Figure 2 and Figure 3 The lifting drive mechanism 5 includes a second motor 51, which is installed on the gantry 2. The output end of the second motor 51 is bolted to a double-groove reel 52, and the double-groove reel 52 has a first synchronous belt 53 and a second synchronous belt 54 wound inside. The top of the gantry 2 is rotatably connected to a third pulley 7, and the surface of the third pulley 7 abuts against the second synchronous belt 54.

[0027] The horizontal brush mechanism 6 includes a horizontal rolling brush 61, and a movable frame 62 is provided at both ends of the horizontal rolling brush 61. A third motor 63 is bolted to one side of the movable frame 62, and a torque sensor is installed on the third motor 63. The torque sensor is a prior art and its working principle is not described here. The output end of the third motor 63 is bolted to the horizontal rolling brush 61, and the other end of the horizontal rolling brush 61 is rotatably connected to another movable frame 62. One end of the first synchronous belt 53 and the second synchronous belt 54 are respectively bolted to the two movable frames 62.

[0028] Specifically, the second motor 51 can drive the double-groove winding wheel 52 to rotate forward and reverse, and can simultaneously unwind and rewind the first synchronous belt 53 and the second synchronous belt 54. The first synchronous belt 53 and the second synchronous belt 54 can drive the two movable frames 62 and the horizontal rolling brush 61 to move up and down.

[0029] refer to Figure 2 and Figure 3 The inner side of the movable frame 62 is rotatably connected with the first pulley 64 and the second pulley 65 respectively, and the inner side of the gantry 2 is bolted with a guide rail 66 adapted to the first pulley 64 and the second pulley 65, and the surfaces of the first pulley 64 and the second pulley 65 are slidably connected to the guide rail 66.

[0030] Specifically, the movable frame 62 can slide along the guide rail 66 via the first pulley 64 and the second pulley 65 , thereby effectively facilitating the stable up and down movement of the rolling brush 61 .

[0031] refer to Figure 1 、 Figure 2 and Figure 4 The surface of the horizontal frame 3 is slidably connected to the vertical brush driver 8, and the bottom of the vertical brush driver 8 is bolted to the vertical roller brush 9. The two ends of the horizontal frame 3 are respectively bolted to the two fixed frames 41, and the surfaces of the driving wheel 44, the driven wheel 45 and the supporting wheel 46 are all slidably connected to the truss 1.

[0032] Specifically, the vertical brush driver 8 can move on the horizontal frame 3, and the vertical brush driver 8 can drive the vertical roller brush 9 to rotate to brush the side of the vehicle. It should be pointed out that the vertical brush driver 8 is an existing technology and its working principle will not be described in detail here.

[0033] Brief description of the usage process: the vehicle is transported and moved inside the truss 1, and the transverse driving mechanism 4 drives the gantry 2 to move transversely inside the truss 1, and the vehicle position is identified by the through-beam sensor. When the vehicle moves, the contact force between the transverse rolling brush 61 and the vehicle is detected by the torque value parameter of the third motor 63. When the vehicle moves, the transverse brush mechanism 6 is lifted and lowered by the lifting driving mechanism 5 according to the set torque value parameter. The lifting driving mechanism 5 drives the transverse brush mechanism 6 to move up and down to fully brush the front and roof of the vehicle. The transverse rolling brush 61 catches up with the rear of the vehicle by judging the vehicle position by the through-beam sensor, and the transverse brush mechanism 6 is lowered to the specified position. The transverse driving mechanism 4 drives the transverse brush mechanism 6 forward to catch up with the rear of the vehicle. When the torque value parameter of the third motor 63 is higher than the preset safety value range, it retreats, and when the torque value parameter of the third motor 63 is lower than the preset safety value range, it leans forward, thereby effectively facilitating the follow-up brushing of the rear of the vehicle, avoiding the inability to fully brush the rear of the vehicle due to the movement of the vehicle.
