The motor 3 is provided with a transmission shaft (not shown), and a transmission gear (not shown) is provided on the transmission shaft. The transmission gear meshes with the outer ring gear, so as to realize the rotation of the inner bearing ring 22 of the bearing 2 and the ring plate 23.

[0034] As Figure 1 and Figure 3 shown, the spray gun bracket 4 is provided on the rotating device 2 for supporting the spray gun 6. The spray gun bracket 4 includes a cylindrical bracket body with an open side and a spray gun support plate 41. The bottom end of the bracket body is fixed on the ring plate 23, and the spray gun support plate 41 is provided on the top end of the bracket body.

[0035] As Figures 1 to 3 shown, the bracket body includes a plurality of vertical rods 42, a top arc ring 43 and a plurality of side arc rings 44. The bottom ends of the plurality of vertical rods 42 are fixed on the ring plate 23. The top ends of the plurality of vertical rods 42 are connected to the top arc ring 43. The upper surface of the top arc ring 43 is connected to the spray gun support plate 41. A plurality of side arc rings 44 connected to the plurality of vertical rods 42 are arranged in parallel and at intervals between the bottom ends of the plurality of vertical rods 42 and the top arc ring 43.

[0036] The spray gun support plate 41 has an arc-shaped structure matching the top arc-shaped ring 43, and the spray gun support plate 41 is provided with a spray gun support hole 45 for the spray gun 6 to pass through. The size of the spray gun support hole 45 is smaller than the size of the spray gun flange 61 of the spray gun 6, so that the spray gun flange 61 just catches on the upper surface of the spray gun support plate 41.

[0037] As Figure 1 and Figure 3 shown, the operating platform 5 and the spray gun support 4 are fixedly arranged with each other. The operating platform 5 is for personnel to stand on it to perform gun replacement operations and is supported by the spray gun support 4. In a preferred embodiment, the operating platform 5 is arranged above the spray gun support plate 41. The operating platform 5 includes a bottom plate 51 and a plurality of guardrails 52 arranged around the bottom plate 51. The operating platform 5 is provided with an operating platform entrance on the same side as the open side of the support body. The size of the bottom plate 51 is larger than the size of the spray gun support plate 41. The part of the bottom plate 51 overlapping with the spray gun support plate 41 has a shape and structure matching the spray gun support plate 41, and also has a through hole allowing the spray gun 6 to pass through, so that the spray gun body 63 of the spray gun 6 can pass through the bottom plate 51 and the spray gun support plate 41 at the same time, and the spray gun flange 61 can catch on the upper surface of the spray gun support plate 41. In a preferred embodiment, the part of the bottom plate 51 overlapping with the spray gun support plate 41 can have the same shape and structure as the spray gun support plate 41, so that the spray gun flange 61 can catch on the upper surface of the bottom plate 51.

One end of the reinforcing rod 7 is connected to the vertical rod 42, and the other end is connected to the lower surface of the bottom plate 51 of the operating platform 5.

[0039] When the spray gun needs to be replaced, the gun replacement trolley of the present utility model is driven by the traveling device 1 to the lower part of the lifting trolley (not shown). The old spray gun is placed in the spray gun support 4 through the lifting trolley, that is, the spray gun body of the old spray gun passes through the spray gun support hole 45 of the spray gun support plate 41 and the hollow interior of the support body in sequence, and finally is inserted into the bearing hole 24 of the bearing 2. At this time, the spray gun flange of the old spray gun catches on the upper surface of the spray gun support plate 41. Then, the gun replacement trolley is driven to the lower part of the crane (not shown). The bearing inner ring 22 and the annular plate 23 of the bearing 2 are driven by the motor 3 to rotate, so that the spray gun support and the operating platform 5 follow the rotation. When rotating to a suitable hoisting position, the personnel board the operating platform 5 and manually connect a component such as a hook of the crane to the spray gun handle 62 of the spray gun. Then, the crane is operated to lift the old spray gun out. Subsequently, a new spray gun is hoisted into the spray gun support of the gun replacement trolley through the crane. The gun replacement trolley is driven to the lower part of the lifting trolley, and the new spray gun is transported to the target position through the lifting trolley. In this way, each replacement of the spray gun is completed in a cycle.
