The mounting plate 203a3 is provided with a plurality of fixing holes 203a4 for fixing the movable spray gun; and the extension plate 203a2 is provided with a harness hole 203a5.

[0037] As a further preferred embodiment of this embodiment, the stroke adjustment unit 2 further includes a support frame 205 arranged on the side wall of the spray box 1, and a cylinder 206 arranged on the support frame 205 and used for driving the vertical stroke frame 201 to move.

[0038] As a further preference of this embodiment, a vertical groove 11 is provided on the side wall of the spray box 1, the support frame 205 is provided on the outside of the spray box 1, and a connecting frame 207 is provided on the vertical travel frame 201, which passes through the vertical groove 11 and is used to be connected to the output end of the cylinder 206.

[0039] As a further preferred embodiment of this embodiment, a fixed spray gun 12 is provided on the top wall of the spray box 1 .

[0040] It can be understood that the fixed spray gun 12 and the movable spray gun are both commonly used spray guns in the art, which are connected to the external powder supply center through the vertical slot 11 through a pipeline, and the control center for controlling the spray gun is located outside the spray box 1. The spray gun, pipeline, control center and other structures are all existing technologies, so they are not repeated. In this embodiment, the pipeline located in the spray box 1 is further fixed by passing through the beam hole 203a5, and the spray gun head is fixed through the fixing hole 203a4.

[0041] The workflow of this embodiment includes two modes: spraying the surface of the accessory and spraying the inner corner of the accessory. The working principle of the accessory surface spraying mode is as follows: the hoisting part hangs the elevator accessory to be sprayed between the two stroke adjustment units, and at the same time opens the movable spray gun on the stroke adjustment unit and the fixed spray gun on the inner top wall, and starts the cylinder to drive the movable spray gun to reciprocate in the vertical direction; the movable spray gun and the fixed spray gun complete the spraying of the accessory surface. The working principle of spraying the inner corner of the accessory is as follows: start the cylinder to drive the movable spray gun to move in the vertical direction until the corner of the accessory, and then start the one-way hydraulic rod to drive the spray gun fixing frame to move along the steering stroke frame. At this time, the spray gun fixing frame first rises along the vertical slide groove to make the movable spray gun spray one side of the corner. When the sliding block moves into the steering groove, the sliding block is driven by the one-way hydraulic rod to squeeze the steering groove, and reacts to the sliding block to make the sliding block rotate along the trajectory of the steering groove, thereby driving the spray gun fixing frame to flip over. When the sliding block rotates 90°, the spray gun fixing frame flips over, and because the hydraulic drive rod has a component force that pushes the sliding block to move toward the horizontal slide groove, the sliding block finally enters the horizontal slide groove and drives the spray gun fixing frame to move horizontally along the horizontal slide groove, thereby making the movable spray gun spray the other side of the corner, and finally completing the spraying of the inner corner of the accessory.

[0042] Compared with the prior art, the paint spraying device provided in this embodiment has the following advantages: through the setting of the stroke adjustment unit, not only can the outer side of the accessory be fully sprayed, but also the inner wall corners of the accessory can be sprayed by fine adjustment to form a unit, without the need for manual repainting, which not only improves the construction efficiency but also avoids damage to the workers' bodies.

[0043] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
