[0033] The following descriptions of the embodiments refer to the attached drawings to illustrate specific embodiments in which the present invention can be implemented.

[0034] The present invention provides a trailer washing device, the structure of which is as follows: Figure 1As shown, it includes a flipping device 1, a trolley 2 and a flushing device 3, wherein the flipping device 1 is used to flip the trailer so that the trailer to be flushed faces downward to the ground. Since the flipping device 1 is a prior art, the structure and working principle of the flipping device 1 are not described in detail; the trolley 2 is arranged under the trailer; the flushing device 3 includes a plurality of flushing nozzles 31 and a plurality of pipelines 32, and the plurality of flushing nozzles 31 are distributed on the trolley 2, and the distribution direction of the plurality of flushing nozzles 31 is horizontal and perpendicular to the travel of the trolley. direction, the flushing nozzle 31 has a plurality of spray holes 310 distributed circumferentially on a horizontal plane and inclined upward. Specifically, the spray hole 310 is inclined upward at an angle of 80° to 90°; the pipeline 32 is arranged in a one-to-one correspondence with the flushing nozzle 31, one end of the pipeline 32 is connected to the corresponding flushing nozzle 31, and the other end is connected to an external pressure generating device, and the external pressure generating device is used to pump a pressure medium to the flushing nozzle 31 through the pipeline 32. Specifically, the pressure medium is water or air.

[0035] In a trailer washing device provided by the present invention, the flipping device 1 can flip the trailer so that the surface to be washed of the trailer faces downward to the ground. In this way, even if the surface to be washed has a pit, the rust residue in the pit can fall off due to gravity after being washed by the washing device 3, thereby having a better washing effect; in addition, the plurality of injection holes 310 on the washing nozzle 31 are distributed along the circumferential direction and inclined upward. On the one hand, the injection holes 310 are inclined upward rather than vertically arranged upward, so that they can spray the inner side of the bent plate bent in the opposite direction of the travel direction of the trolley 2. On the other hand, the plurality of injection holes 310 on the flushing nozzle 31 are distributed circumferentially, so that the inner side of the bent plate bent in any direction can be flushed, and the paths of the pressure medium flows ejected from adjacent flushing nozzles 31 can be intersected, so that the trailer can be covered and flushed in a direction perpendicular to the traveling direction of the trolley 2, thereby achieving an ideal flushing effect.

[0036] Specifically, the flushing nozzle 31 includes a nozzle seat rod 311 connected to the pipeline 32 and a pressure relief nozzle cap 312 covered at the top of the nozzle seat rod 311, and a plurality of the injection holes 310 are opened on the pressure relief nozzle cap 312;

[0037] The plurality of injection holes 310 on the pressure relief nozzle cap 312 are tilted toward one side together on a horizontal plane, so that the pressure relief nozzle cap 312 can rotate under the driving of the pressure medium.

[0038] It can be understood that, due to the intervals between the plurality of circumferentially distributed injection holes 310, the portion of the trailer corresponding to the intervals is difficult to flush, and by setting the plurality of injection holes 310 on the pressure relief nozzle cap 312 to be tilted toward one side together on the horizontal plane, the pressure relief nozzle cap 312 can rotate under the drive of the pressure medium, and the pressure medium sprayed by the rotating pressure relief nozzle cap 312 can flush the portion that cannot be flushed in the above-mentioned intervals, so that the trailer can be fully flushed. It is not difficult to understand that the combined structure of the nozzle seat rod 311 and the pressure relief nozzle cap 312 is similar to the pressure relief valve on a pressure cooker, which can rotate while relieving pressure, so the specific shape and structure of the injection hole 310 will not be described in detail.

[0039] It should be noted that setting the pressure relief nozzle cap 312 in a rotatable manner to flush the portion corresponding to the above-mentioned interval is only a preferred embodiment of the present scheme. In other embodiments, the plurality of injection holes 310 on the pressure relief nozzle cap 312 can also be connected in the circumferential direction. At this time, the plurality of injection holes 310 form a whole, and the pressure medium ejected therefrom is in a ring shape, thereby eliminating the intervals between the circumferentially distributed injection holes 310.

[0040] Preferably, the entirety or the end of the injection hole 310 is trumpet-shaped, so that the jet ejected from the injection hole 310 is radial, which can increase the coverage area of ​​the jet ejected from the injection hole 310, thereby improving the flushing efficiency.

[0041] Furthermore, in order to prevent the pressure relief nozzle cap 32 from falling off from the top of the nozzle seat rod 311 under the impact of the pressure medium, the flushing nozzle 31 further includes a plurality of elastic clips 313 circumferentially distributed at the bottom of the pressure relief nozzle cap 32, and the top of the nozzle seat rod 311 passes through the middle of the plurality of elastic clips 313;

[0042] The top end of the nozzle seat rod 311 extends radially outward to form a protrusion 3110 to cooperate with the elastic retaining wire 313 at the bottom end of the pressure relief nozzle cap 312 to prevent the pressure relief nozzle cap 312 from falling off from the top end of the nozzle seat rod 311 under the impact of pressure.

[0043] According to an embodiment of the present invention, the flushing device 3 further includes a plurality of telescopic driving members 33, a distance sensor 34 and a control module 35 which are arranged one by one in correspondence with the flushing nozzles 31, wherein the telescopic driving member 33 may be any one of a pneumatic cylinder and a hydraulic cylinder; the nozzle seat rod 311 and the distance sensor 34 are both fixedly connected to the output end of the corresponding telescopic driving member 33;

[0044] The control module 35 is preset with a distance value, and the distance sensor 34 is used to measure the vertical distance between the corresponding flushing nozzle 31 and the surface of the trailer to be flushed. The corresponding control module 35 controls the telescopic drive member 33 in real time so that the vertical distance between the corresponding flushing nozzle 31 and the surface of the trailer to be flushed reaches the preset distance value.

[0045] Due to the complex structure of the trailer, its surface is usually uneven, and the closer the flushing nozzle 31 is to the trailer, the better the flushing effect. Therefore, the telescopic drive member 33 needs to be provided to adjust the corresponding distance between the flushing nozzle 31 and the trailer surface; and the control module 35 can adjust the flushing nozzle 31 to a preset distance in real time according to the distance value between the flushing nozzle 31 and the trailer measured by the distance sensor 34, so as to always maintain a good flushing effect.

[0046] Furthermore, since the paths of the pressure medium flows sprayed by the adjacent flushing nozzles 31 intersect with each other, in order to avoid the impact forces of the pressure medium flows sprayed by the adjacent flushing nozzles 31 from canceling each other out when crossing, the flushing device 3 further includes a plurality of solenoid valves 36 corresponding to the pipelines 32 one by one, and the solenoid valves 36 are electrically connected to the corresponding control modules 35;

[0047] The control module 35 is used to control the corresponding solenoid valve 36 so that the adjacent solenoid valves 36 are staggered to open or close.

[0048] It should be noted that the staggered opening or closing of adjacent solenoid valves 36 means that the adjacent solenoid valves 36 are not opened or closed at the same time, so that the adjacent flushing nozzles 31 do not work at the same time, thereby avoiding conflicts between the pressure medium flows sprayed by the adjacent flushing nozzles 31. As a preferred embodiment, the plurality of solenoid valves 36 can be sorted, and the solenoid valves 36 in odd positions and the solenoid valves 36 in even positions are opened or closed alternately.

[0049] The present invention further provides a trailer washing workshop, which includes the trailer washing equipment and a workshop body 100 , and the turning device 1 is fixedly arranged inside the workshop body 100 .

[0050] Furthermore, the trailer washing workshop further comprises two rails 200 fixedly arranged at the bottom of the workshop body 100 for guiding the trolley 2. Preferably, in order to reduce the volume of the turning device 1 and the trolley 2, the rails 200 extend along the length direction of the trailer.

[0051] In order to facilitate the understanding of this scheme, the following Figure 1-Figure 5The working principle of a trailer washing device and a trailer washing workshop provided by the present invention is described in detail:

[0052] During operation, the trailer treated by the sandblasting and rust removal process is placed on a load-carrying trolley and towed into the interior of the workshop body 100. Specifically, the load-carrying trolley can share the track 200 with the trolley 2. The flipping device 1 is started to flip the side of the trailer to be washed downward toward the ground.

[0053] Start an external pressure generating device such as a water pump to pump clean water to the flushing device 3, wherein the clean water flows to the corresponding flushing nozzle 31 through the multiple pipelines 32 and the solenoid valve 36, and is sprayed upwardly through the multiple spray holes 310 opened on the flushing nozzle 31; since the multiple spray holes 310 on the flushing nozzle 31 are circumferentially distributed, the inner side of the bent plate bent in any direction on the surface to be flushed of the trailer can be flushed. In addition, since the multiple spray holes 310 on the pressure relief nozzle cap 312 are tilted toward one side together on the horizontal plane, the pressure relief nozzle cap 312 can rotate around the nozzle seat rod 311 under the drive of the pressure medium, and during the rotation, the multiple spray holes 310 on the pressure relief nozzle cap 312 can form a continuous, annular flushing surface on the horizontal plane. Since the plurality of flushing nozzles 31 are distributed on the trolley 2, the plurality of spray holes 310 on the flushing nozzles 31 are distributed in the circumferential direction and tilted upward, which will inevitably cause cross paths and conflicts between the pressure media sprayed from the adjacent flushing nozzles 31, thereby weakening the pressure of the pressure media sprayed from the flushing nozzles 31; and by setting the control module 35 to control the start and stop of the corresponding flushing nozzles 31, the adjacent flushing nozzles 31 can be made to work in a staggered manner, thereby avoiding conflicts between the pressure media sprayed from the adjacent flushing nozzles 31.

[0054] The trolley 2 is started to drive the flushing device 3 to move along the length direction of the surface to be flushed (i.e., the length direction of the trailer), so as to flush one surface to be flushed of the trailer. During the movement of the flushing device 3, the distance sensor 34 can measure in real time the vertical distance between the corresponding flushing nozzle 31 and the surface to be flushed of the trailer, and the control module 35 can adjust the flushing nozzle 31 based on the measured value so that the distance between the flushing nozzle 31 and the surface to be flushed of the trailer reaches a preset value, thereby ensuring the flushing effect of the flushing nozzle 31.

[0055] When one surface of the trailer is washed, the flip device 1 is operated again to flip the other surface to be washed downward to face the ground; the above arrangement is repeated until the entire surface of the trailer is washed. It should be noted that since the front and rear of the trailer have a small area, the washing can be done manually with a handheld spray gun.

[0056] In summary, in a trailer washing equipment and a trailer washing workshop provided by the present invention, the flipping device 1 can flip the trailer so that the surface to be washed is facing downward to the ground, and the trolley 2 can drive the washing device 3 to move under the trailer to wash the lower surface of the trailer. During washing, the rust residue is impacted by the pressure medium and falls off from the surface of the trailer, and is freely separated by gravity, thereby avoiding residual rust residue in the pits on the surface of the trailer; the plurality of injection holes 310 on the washing nozzle 31 are distributed circumferentially and wash upward, thereby realizing the washing of the complex surface of the trailer.

[0057] It should be noted that although the present invention is disclosed as above by specific embodiments, the above embodiments are not intended to limit the present invention. Ordinary technicians in this field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
