[0004] The technical solutions disclosed in the aforementioned patent documents can achieve uniform coating on the side walls of the generator set housing. However, practical experience has shown that the following technical problems still exist:

[0005] There are limitations in its use. This spraying device can only coat the side walls of the box, but cannot coat the top of the box, making it difficult to coat the top and side walls simultaneously.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] This utility model addresses the shortcomings of the prior art by providing an automatic spraying device for generator set housings, which can simultaneously coat the top and side walls of the housing, significantly improving spraying efficiency and flexibility.

[0008] To solve the above technical problems, the present invention adopts the following technical solution:

[0009] The generator set enclosure automatic spraying device includes a horizontally set hollow main arm, with inclined swing arms hinged to both ends of the hollow main arm. The hollow main arm is hinged to the middle of the swing arms, and the bottom ends of the two swing arms are fixedly connected to horizontally set hollow auxiliary arms. The hollow auxiliary arms can swing 90° along the hinge point in the middle of the swing arms.

[0010] The bottom of both the hollow main arm and the hollow auxiliary arm is equipped with multiple evenly distributed nozzles, and the interior of both the hollow main arm and the hollow auxiliary arm is provided with a spray pipe, with the nozzles connected to the inner cavity of the spray pipe.

[0011] A fixed base is fixedly installed directly above the hollow main arm, and a first hydraulic telescopic cylinder is connected between the fixed base and the swing arms on both sides.

[0012] Furthermore, multiple nozzles at the bottom of the hollow main boom and hollow auxiliary boom are located in the same plane.

[0013] Furthermore, one end of the first hydraulic telescopic cylinder is hinged to the fixed seat, and the other end of the first hydraulic telescopic cylinder is hinged to the top of the swing arm.

[0014] Furthermore, a second hydraulic telescopic cylinder arranged vertically is installed on the left and right sides of the fixed base.

[0015] Furthermore, the head of the second hydraulic telescopic cylinder is hinged to the top of the hollow main arm, and the tail of the second hydraulic telescopic cylinder is hinged to the bottom of the moving trolley.

[0016] Furthermore, telescopic arms arranged vertically are installed on the opposite outer sides of the two second hydraulic telescopic cylinders.

[0017] Furthermore, the bottom end of the telescopic arm is fixedly connected to the top of the hollow main arm, and the top of the telescopic arm is fixedly connected to the bottom of the mobile trolley.

[0018] Furthermore, the mobile trolley is mounted above two side-by-side top rails.

[0019] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0020] In this utility model, the first hydraulic telescopic cylinder extends so that the hollow auxiliary arm can swing 90° along the hinge in the middle of the swing arm, so that the hollow main arm and the hollow auxiliary arm are set vertically. The nozzles on the hollow main arm and the hollow auxiliary arm can work synchronously to achieve synchronous coating of the top and side walls of the box, resulting in high spraying efficiency.

[0021] When the top of the box to be sprayed needs to be sprayed, the nozzle at the bottom of the hollow main arm works, while the nozzle at the bottom of the hollow auxiliary arm does not work. Spraying is achieved during the lateral movement of the hollow main arm.

[0022] When one side of the box to be painted needs to be painted, the hollow auxiliary arm on the corresponding side is in a vertical position, and the painting is achieved during the horizontal movement of the hollow auxiliary arm.

[0023] This invention allows for structural adjustments based on spraying requirements, thereby improving spraying flexibility.

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown in the figure, this utility model provides an automatic spraying device for generator set housing, including a horizontally arranged hollow main arm 1, with inclined swing arms 2 respectively hinged to both ends of the hollow main arm 1, the hollow main arm 1 and the swing arms 2 being hinged at the middle, and the bottom ends of the two swing arms 2 being fixedly connected to horizontally arranged hollow auxiliary arms 3, the hollow auxiliary arms 3 being able to swing 90° along the hinge point at the middle of the swing arms 2.

[0030] The bottom of both the hollow main arm 1 and the hollow auxiliary arm 3 is equipped with a plurality of evenly distributed nozzles 4, and the plurality of nozzles 4 at the bottom of the hollow main arm 1 and the hollow auxiliary arm 3 are located in the same plane.

[0031] Both the hollow main arm 1 and the hollow auxiliary arm 3 are equipped with spray pipes, and the nozzle 4 is connected to the inner cavity of the spray pipe.

[0032] A fixed base 6 is fixedly installed directly above the hollow main arm 1. A first hydraulic telescopic cylinder 5 is connected between the fixed base 6 and the swing arms 2 on both sides. One end of the first hydraulic telescopic cylinder 5 is hinged to the fixed base 6, and the other end of the first hydraulic telescopic cylinder 5 is hinged to the top of the swing arm 2.

[0033] The left and right sides of the fixed base 6 are respectively equipped with a second hydraulic telescopic cylinder 9 arranged in the vertical direction. The head of the second hydraulic telescopic cylinder 9 is hinged to the upper part of the hollow main arm 1, and the tail of the second hydraulic telescopic cylinder 9 is hinged to the bottom of the mobile trolley 8.

[0034] The second hydraulic telescopic cylinder 9 provides power for the lifting and lowering of the hollow main boom 1 and the hollow auxiliary boom 3.

[0035] Two telescopic arms 7, arranged vertically, are installed on the opposite outer sides of the two second hydraulic telescopic cylinders 9. The bottom end of the telescopic arm 7 is fixedly connected to the top of the hollow main boom 1, and the top of the telescopic arm 7 is fixedly connected to the bottom of the moving trolley 8. The telescopic arm 7 serves as a guide to ensure the smooth, accurate, and safe lifting and lowering of the hollow main boom 1 and the hollow auxiliary boom 3.

[0036] The mobile trolley 8 is installed above two parallel top slide rails 10, and the mobile trolley 8 can reciprocate along the top slide rails 10.

[0037] The specific working principle of this utility model is as follows:

[0038] When the box 11 to be sprayed enters the spraying station, the second hydraulic telescopic cylinder 9 drives the hollow main arm 1 and the hollow auxiliary arm 3 to descend to a suitable height.

[0039] When the top and both sides of the box 11 to be sprayed need to be sprayed, the two first hydraulic telescopic cylinders 5 extend respectively, so that the hollow auxiliary arm 3 can swing 90° along the hinge in the middle of the swing arm 2, so that the hollow main arm 1 and the hollow auxiliary arm 3 form an inverted U-shaped structure. The nozzles 4 on the hollow main arm 1 and the hollow auxiliary arm 3 work synchronously. At the same time, the moving trolley 8 drives the hollow main arm 1 and the hollow auxiliary arm 3 to move laterally to achieve spraying, and the spraying efficiency is high.

[0040] When the top of the box 11 to be sprayed needs to be sprayed, the nozzle 4 at the bottom of the hollow main arm 1 works, while the nozzle 4 at the bottom of the hollow auxiliary arm 3 does not work. The hollow main arm 1 achieves spraying during the lateral movement.

[0041] When one side of the box 11 to be sprayed needs to be sprayed, the hollow auxiliary arm 3 on the corresponding side is in a vertical state, and the hollow auxiliary arm 3 achieves spraying during the lateral movement.
