[0035] In Embodiment 2, the positioning shaft 2 and the bushing 4 are replaced by a square shaft and a square tube, etc., as Figure 12 shown. A fixing iron sheet 14 is welded below the bushing 4. A bolt is welded in the middle of the iron sheet 14. The welded bolt is passed through the positioning hole on the channel steel 3 and tightened with a nut to fix the bushing.

[0036] The motor supporting structure includes a motor support plate 7 and a motor support plate adjusting seat 6. At both ends of the outside of the motor support plate adjusting seat 6, bushing fixing ear plates 5 are fixedly connected. A bushing 4 is fixedly connected inside the cavity of the bushing fixing ear plate 5. The bushing 4 is adapted to the positioning shaft 2. The bushing 4 is sleeved on the positioning shaft 2, and the motor support plate adjusting seat 6 is located above one end of the two channel steels 3. Through the setting of the connection method between the motor support plate adjusting seat 6 and the channel steel 3, the motor support plate adjusting seat 6 can be quickly disassembled and assembled. And the setting of the two bushings 4 can position the motor support plate adjusting seat 6, so that when the motor support plate adjusting seat 6 is installed, its position can be kept consistent.

[0037] An arc-shaped long hole one is opened on the motor support plate adjusting seat 6, and a vertical hole is opened on the motor support plate 7. The arc-shaped long hole one and the vertical hole are connected by bolts. The motor support plate 7 is located inside the motor support plate adjusting seat 6, and vertical holes are symmetrically arranged on the motor support plate 7. The vertical holes and the arc-shaped long hole two are in a cross state. The motor support plate 7 is located inside the motor support plate adjusting seat 6. Through the setting of the arc-shaped long hole one and the vertical hole, the position of the motor support plate 7 can be adjusted up, down, left and right to meet the disassembly and assembly requirements of motors with different models and different installation positions. When the position of the motor support plate 7 is adjusted to be closely attached to the motor 13, the connection bolts between the motor support plate adjusting seat 6 and the motor support plate 7 are tightened.

[0038] A second wear-resistant plate 11 is fixedly connected to the top of the motor support plate 7. The motor support plate 7 and the second wear-resistant plate 11 can be connected by countersunk bolts, and the purpose is to protect the motor housing.

[0039] The shot blasting machine supporting structure includes a shot blasting machine housing support plate adjusting seat 8 and a shot blasting machine housing support plate 9. At both ends of the outside of the shot blasting machine housing support plate adjusting seat 8, another bushing fixing ear plate 5 is fixedly connected. Another bushing 4 is fixedly connected inside the cavity of the another bushing fixing ear plate 5. The another bushing 4 is adapted to the positioning shaft 2. The another bushing 4 is sleeved on the positioning shaft 2, and the shot blasting machine housing support plate adjusting seat 8 is located above the other ends of the two channel steels 3. The shot blasting machine housing support plate adjusting seat 8 can be quickly disassembled and assembled.

[0040] The shot blasting machine housing support plate 9 is located inside the shot blasting machine housing support plate adjusting seat 8. Arc-shaped long holes II are evenly formed in the shot blasting machine housing support plate 9. The centers of rotation of all the arc-shaped long holes II are the same. A round hole is formed in the shot blasting machine housing support plate adjusting seat 8. The number of the round holes is the same as that of the arc-shaped long holes II. The round hole and the arc-shaped long hole II are connected by bolts. Through the arrangement of the round hole and the arc-shaped long hole II, the relative angle between the shot blasting machine housing support plate adjusting seat 8 and the shot blasting machine housing support plate 9 can be adjusted. When the angle of the shot blasting machine housing support plate 9 is adjusted to be able to tightly clamp the shot blasting machine 12, the connecting bolts between the shot blasting machine housing support plate adjusting seat 8 and the shot blasting machine housing support plate 9 are tightened. A first wear-resistant plate 10 is fixedly connected to the top of the shot blasting machine housing support plate 9. The shot blasting machine housing support plate 9 and the first wear-resistant plate 10 can be connected by countersunk bolts, and the purpose is to protect the shot blasting machine housing.

[0041] In some embodiments of the present application, the channel steel 3 is welded to the upper surface of the mobile lifting platform 1. The bushing 4 and the bushing fixing ear plate 5 are connected by welding, and the motor support plate adjusting seat 6 and the bushing fixing ear plate 5 are connected by welding. The three are welded into an integral body; the bushing 4, the bushing fixing ear plate 5 and the shot blasting machine housing support plate adjusting seat 8 are welded into an integral body in the same way.

[0042] The above-mentioned mobile lifting platform 1 can be a mobile lifting hydraulic platform trolley, a hydraulic truck, a screw platform truck and other mobile lifting platforms. The materials of the first wear-resistant plate 10 and the second wear-resistant plate 11 can be wear-resistant buffer materials such as wear-resistant rubber and wear-resistant sponge.

In Embodiment 3, when the installation positions of the shot blasting machine 12 and the motor 13 are interchanged, the positions of the motor support plate adjusting seat 6 and the shot blasting machine housing support plate adjusting seat 8 can be changed, so as to facilitate maintenance, as Figure 9 and Figure 10 shown.

[0044] In Embodiment 4, asFigures 13 to 14 As shown in the figure, racks are added to the inner walls of the arc-shaped long strip holes in the middle of the shot blasting machine housing support plate 9, and the gear 15 is engaged with the racks. A rotating handle 16 is welded (or bolted, etc.) behind the gear 15. When the rotating handle 16 is rotated, the gear 15 rotates accordingly, thereby driving the angle adjustment of the shot blasting machine housing support plate 9. When the angle of the shot blasting machine housing support plate 9 is adjusted to the appropriate position, the bolts on both sides of the shot blasting machine housing support plate 9 are tightened, so as to achieve the purpose of closely fitting with the shot blasting machine housing, and this method is more labor-saving and convenient.

[0045] In summary: When the shot blasting machine lifting and maintenance platform is in use, the positions of the motor support plate 7 and the shot blasting machine housing support plate 9 can both be adjusted according to requirements, so that the shot blasting machine lifting and maintenance platform can adapt to the installation positions of the shot blasting machines 12 at different angles, improving the adaptability of the shot blasting machine lifting and maintenance platform. The maintenance platform can tightly hold the shot blasting machine 12, facilitating the maintenance of the shot blasting machine 12. And when the installation positions of the shot blasting machine housing and the motor are interchanged, the positions of the motor support plate adjusting seat 6 and the shot blasting machine housing support plate adjusting seat 8 can be adjusted by replacing them, thus facilitating the maintenance.
