The vehicle body 300 is provided with a handle 350 for easy movement.

As shown in fig. 2, the spray booth 100 includes a spray head 130, a distance bar 110, and a support column 120. The distance rod 110 is a long rod arranged along the sliding direction of the painting booth 100, the support pillar 120 is vertically fixed on the upper surface of the distance rod 110, the spray head 130 is fixedly connected on the top of the support pillar 120, and the nozzle 131 of the spray head 130 faces the front of the painting booth 100 and communicates with the supply device. Therefore, when the front end of the distance rod 110 abuts against the spraying surface, the distance between the spray head 130 and the sprayed wall can be kept fixed, and the support column 120 supports the spray head 130 to a certain height, so that the coating is prevented from being directly sprayed on the distance rod 110. The plurality of spray racks 100 are arranged side by side in parallel, the plurality of spray racks 100 are uniformly distributed in the left-right direction, the distance between each spray head 130 and a spray surface can be kept the same by using the distance rods 110, the spray effect of each spray head 130 is ensured to be consistent, and the spray rack is particularly suitable for spraying of curved spray surfaces, such as the surfaces of piers.

In order to ensure that the positioning point of the distance rod 110 in contact with the wall body can be sprayed with paint, the front end of the distance rod 110 can be set to be a telescopic structure, the front end of the rod is retracted after the distance is finished, and the distance rod gives way for spraying, and the following structure can be adopted: as shown in fig. 2 and 3, the distance rod 110 comprises a rod body 111, a core rod 112 slidably arranged in the rod body 111, and a return spring 113 connecting the core rod 112 and the rod body 111.

A spring groove 118 is arranged behind the sliding hole 117, the return spring 113 is sleeved in the core rod 112 and is arranged in the spring groove 118, a limiting opening 116 is formed in the left side wall and the right side wall of the spring groove 118, a shifting block 114 is fixedly connected to the tail end of the core rod 112, the left end and the right end of the shifting block 114 extend out of the rod body 111 from the limiting opening 116 to facilitate operation of a user, and two ends of the return spring 113 are respectively abutted against the front end faces of the spring groove 118 and the shifting block 114. When the shifting block 114 abuts against the front end face of the limiting opening 116, the front end of the core rod 112 slides out of the front end face of the rod body 111, and the return spring 113 is in a compressed state; when no external force acts on the return spring 113, the front end of the stem 112 is retracted inside the rod body 111. When the spraying device is used, an operator pushes the shifting block 114 forwards to enable the core rod 112 to extend out of the rod body 111 until the shifting block 114 abuts against the front end face of the limiting opening 116, the shifting block 114 and the rod body 111 cannot move relatively and move forwards to contact with a wall body to complete spacing, the shifting block 114 is released at the moment, the core rod 112 automatically resets under the action of the return spring 113, and the front end of the spacing rod 110 is separated from the wall body to reserve a space for spraying. The bottom of the rod body 111 is provided with a sliding block 115, the upper surface of the lifting frame 200 is provided with a sliding groove matched with the sliding block 115, and an anti-slip layer can be arranged between the sliding block 115 and the sliding groove to increase the static friction force between the sliding block 115 and the sliding groove so as to prevent the spraying frame 100 from moving at will after a certain distance. It should be noted that the height of the adjacent spray painting racks 100, the distance between the adjacent spray painting racks and the supporting upright posts 120 and the spraying range of the nozzles 131 need to be consistent, so that the spraying ranges before the adjacent spray painting racks 100 are connected, and the spraying range can cover the lowest point of the wall when the lifting frame 200 is located at the lowest point.

As shown in fig. 1 and 2, in order to facilitate the communication between each spray head 130 and the supply device, each spray head 130 is provided with at least two connectors 132 for connecting water pipes, the connectors 132 are communicated with the nozzles 131, the spray heads 130 on adjacent spray racks 100 are communicated with each other through a connection hose 420, two ends of the connection hose 420 are respectively connected with the connectors 132 of the two spray heads 130, and the hose is used to adapt to the sliding adjustment of the spray racks 100. Preferably, a valve (not shown) is provided on each segment of the connection hose 420, and the valve on a portion of the connection hose 420 can be closed to disable a portion of the spray head 130 from being supplied with paint when the desired spray area is small. The supply means includes a paint tank 400, a supply hose 410 for connecting the paint tank 400 to one of the spray heads 130, and a supply pump provided in the paint tank 400, and having a discharge port connected to the supply hose 410, and is adapted to be lifted and lowered by the crane 200 by hose supply. If only two connectors 132 are provided on all the spray heads 130, the supply hose 410 may be connected to the connectors 132 of the spray heads 130 located at the edge, if more than three connectors 132 are provided on any of the spray heads 130, the supply hose 410 may be connected to any of the connectors 132 that are not used, and an end cap may be provided on the connector 132 that is not connected to the connection hose 420 or the supply hose 410 to prevent the paint from flowing out. In this embodiment, three connectors 132 are provided on one of the nozzles 130 located at the edge, and the supply hose 410 is connected to this nozzle 130.

As shown in fig. 4, in order to increase the painting area, an extension frame 500 may be provided on the crane 200, and a plurality of painting stands 100 may be provided side by side in the extension frame 500 and the crane 200. The both sides of extension frame 500 and crane 200 are provided with respectively and are used for connecting engaging lug 240 each other, have seted up the connecting hole on the engaging lug 240, and the engaging lug 240 of the two passes through bolted connection, and extension frame 500 and crane 200 can rotate and fix relatively around the connecting hole axis, and when some curved surface curvatures are great, distance rod 110 adjustable distance is insufficient, can further adapt to curved surface spraying face shape through changing the contained angle between crane 200 and extension frame 500. The spray head 130 of the extension bracket 500 is communicated with the adjacent spray head 130 of the crane 200 through the connection hose 420.

Before the spraying device is used, whether the expansion frame 500 is installed or not and the installation angle of the expansion frame 500 and the lifting frame 200 are determined according to the shape and the area of a spraying surface to be sprayed, after the shape of the device is determined, the vehicle body 300 is moved to the front of a wall body, the spraying heads 130 of the spraying frames 100 are adjusted one by one to be spaced, a feeding pump of a feeding device is started to start spraying, and the lifting frame 200 is driven to move upwards to continuously spray.
