[0031] Example:

[0032] See also Figure 1-7 , a maintenance work platform convenient for adjustment and storage, comprising a bottom frame 1, a top workbench 2 is arranged on the top of the bottom frame 1, both ends of the top of the bottom frame 1 are rotatably connected with support components 4, the top of the support component 4 is rotatably connected with a transverse moving frame 8, the transverse moving frame 8 is located inside the top workbench 2 and is slidably connected to the top workbench 2, and an adjusting mechanism for adjusting the transverse movement of the top workbench 2 is arranged inside the transverse moving frame 8;

[0033] A longitudinal polished rod 5 is fixed inside the bottom frame 1, and a first hydraulic cylinder 6 is rotatably connected to the outer side of the longitudinal polished rod 5 through a bearing, and a longitudinal guide rod 7 is rotatably connected to the output end of the first hydraulic cylinder 6 through a bearing. The longitudinal guide rod 7 is located inside one of the support assemblies 4 and is rotatably connected to the support assembly 4;

[0034] The four end corners of the top of the bottom frame 1 are all provided with rotatable moving wheels 3, and the top of the bottom frame 1 is provided with a rotating mechanism for rotating the moving wheels 3;

[0035] The support assembly 4 is composed of two vertical support plates 41, a cross support plate 42 and a longitudinal support plate 43. The two vertical support plates 41 are symmetrically arranged. A cross support plate 42 is fixed between the two vertical support plates 41. A vertical support plate 41 is fixed on the top between the two vertical support plates 41. By arranging the cross support plate 42 and the longitudinal support plate 43, the two vertical support plates 41 can be better connected, thereby improving the supporting strength of the two vertical support plates 41.

[0036] Here, the operation of the first hydraulic cylinder 6 enables the support assembly 4 to rotate, thereby enabling the top workbench 2 to move relative to the bottom frame 1. When the top workbench 2 moves toward the bottom frame 1, the occupied height of the device is reduced, so as to facilitate the carrying of the device. The operation of the first hydraulic cylinder 6 can adjust the position height of the top workbench 2 to meet the needs of operations at different heights.

[0037] The adjustment mechanism includes a transverse light rod 10, the transverse light rod 10 is fixed inside the transverse moving frame 8, the two ends of the outer side of the transverse light rod 10 are slidably connected with transverse moving plates 11, both sides of the transverse moving plate 11 are rotatably connected with oblique rotating rods 12, the side of the oblique rotating rod 12 away from the transverse moving plate 11 is rotatably connected with a longitudinal limit column 13, both sides of the inside of the transverse moving frame 8 are slidably connected with transverse sliding rods 9, and the transverse sliding rods 9 are located inside the top workbench 2 and fixedly connected to the top workbench 2;

[0038] A plurality of rectangular limit grooves adapted to the longitudinal limit columns 13 are evenly distributed inside the transverse sliding rod 9, so that the longitudinal limit columns 13 can enter the interior of the rectangular limit grooves, so that the longitudinal limit columns 13 can limit the sliding of the transverse sliding rod 9 inside the transverse moving frame 8. When the longitudinal limit columns 13 move out of the transverse sliding rod 9, the transverse moving frame 8 can slide on the outside of the transverse sliding rod 9, thereby enabling the top workbench 2 to move on the top of the bottom frame 1;

[0039] Here, when it is necessary to adjust the lateral position of the top workbench 2, the lateral moving plate 11 is pushed so that the two lateral moving plates 11 are close to each other, so that the lateral moving plates 11 can slide on the outside of the lateral light rod 10, and the movement of the lateral moving plate 11 causes the lateral rigid spring 14 to be subjected to a phase change of force, and the movement of the lateral moving plate 11 enables the longitudinal limit column 13 to slide inside the lateral moving frame 8 through the oblique rotating rod 12, and when the longitudinal limit column 13 moves out of the interior of the lateral sliding rod 9, the lateral sliding rod 9 can slide inside the lateral moving frame 8, so that the top workbench 2 can be adjusted in the lateral position, so that the top workbench 2 can be adjusted in the lateral position, so that the vertical center of the top workbench 2 can be aligned with the bottom frame 1, thereby improving the stability and supporting performance of the top workbench 2;

[0040] The rotating mechanism includes a second hydraulic cylinder 15, which is fixed to the top of the bottom frame 1, and a transverse moving seat 16 is fixed to the output end of the second hydraulic cylinder 15, one end of the transverse moving seat 16 is rotatably connected to a transverse transmission plate 17 through a pin shaft, one end of the transverse transmission plate 17 is rotatably connected to an L-shaped rotating plate 18 through a pin shaft, and the bottom of the L-shaped rotating plate 18 is rotatably connected to the moving wheel 3 through a pin shaft;

[0041] The inside of the L-shaped rotating plate 18 is rotatably connected to a longitudinal support shaft 19 through a bearing. The longitudinal support shaft 19 is close to one side of the bottom frame 1 and is fixedly connected to the bottom frame 1, so that the L-shaped rotating plate 18 can rotate on the outside of the longitudinal support shaft 19, so that the moving wheel 3 can rotate;

[0042] Here, the operation of the second hydraulic cylinder 15 enables the transverse moving seat 16 to move, and the movement of the transverse moving seat 16 enables the L-shaped rotating plate 18 to rotate around the longitudinal support shaft 19 as the center through the transverse transmission plate 17. When the moving wheel 3 contacts the ground and the bottom frame 1 is separated from the ground, the bottom frame 1 can be moved conveniently. When the moving wheel 3 is rotated and the bottom frame 1 contacts the ground, the occupied height of the device can be reduced to facilitate the storage of the device.

[0043] During use: when the lateral position of the top workbench 2 needs to be adjusted, the lateral moving plate 11 is pushed so that the two lateral moving plates 11 are close to each other, so that the lateral moving plate 11 can slide on the outside of the lateral light rod 10, and the movement of the lateral moving plate 11 causes the lateral rigid spring 14 to be subjected to a phase change of force, and the movement of the lateral moving plate 11 enables the longitudinal limit column 13 to slide inside the lateral moving frame 8 through the oblique rotating rod 12, and when the longitudinal limit column 13 moves out of the interior of the lateral sliding rod 9, the lateral sliding rod 9 can slide inside the lateral moving frame 8, so that the top workbench 2 can be adjusted in the lateral position, so that the top workbench 2 can be adjusted in the lateral position, so that the vertical center of the top workbench 2 can be aligned with the bottom frame 1, thereby improving the stability and supporting performance of the top workbench 2;

[0044] The operation of the second hydraulic cylinder 15 enables the transverse moving seat 16 to move. The movement of the transverse moving seat 16 enables the L-shaped rotating plate 18 to rotate around the longitudinal support shaft 19 as the center through the transverse transmission plate 17. When the moving wheel 3 contacts the ground and the bottom frame 1 is separated from the ground, the bottom frame 1 can be moved conveniently. When the moving wheel 3 is rotated and the bottom frame 1 contacts the ground, the occupied height of the device can be reduced to facilitate the storage of the device.
