Description

Technical Field

[0001] The invention relates to the technical field of automobile maintenance, in particular to a vehicle maintenance platform. Background Art

The hydraulic cylinder of the car needs regular inspection and maintenance after years of use. The hydraulic cylinder is a hydraulic actuator that drives the reciprocating motion of mechanical parts. In order to facilitate the inspection of the vehicle hydraulic cylinder, a vehicle maintenance platform is required.

[0003] At present, vehicle hydraulic cylinder maintenance platforms mostly use clamps to fix the hydraulic cylinders. When the angle of the hydraulic cylinder needs to be adjusted, it is not convenient to rotate the hydraulic cylinder and it is not convenient to remove the nuts on the hydraulic cylinder. When each hydraulic cylinder is inspected, it is necessary to take and put the inspection tools. The inspection tools are placed in a messy manner and can be taken out and used at will when not being inspected. The environment in the workshop is relatively complex, which makes it easy for the inspection tools to be lost. When inspection is needed, the corresponding inspection tools cannot be found; when the waste hydraulic oil is collected, it is easy to cause pollution, and it will also cause oil stains to adhere to the filter, which is difficult to clean.

The groove 42 on the side wall of the collecting box 41 is convenient for taking the collecting box 41; by setting the size of the collecting box 41 to be larger than the size of the filter 43, when it is necessary to clean the waste hydraulic oil inside the collecting box 41, first pull the groove 42, so that the groove 42 drives the collecting box 41 to come in a small range, so that the collecting box 41 can be cleaned. The collecting box 41 moves back and forth to prevent the hydraulic oil from dripping into the interior of the fixed platform 1 when the collecting box 41 moves too much; when the collecting box 41 moves back and forth, the top wheel 45 will be squeezed with the arc block 49, so that the arc block 49 can be in constant contact with the top wheel 45, and then the arc block 49 will drive the filter screen 43 to shake continuously, so that the oil attached to the filter screen 43 can be quickly cleaned into the interior of the collecting box 41, avoiding the problem of hydraulic oil dripping continuously from the filter screen 43 after the collecting box 41 is pulled out, thereby improving the efficiency of cleaning the filter screen 43; the collecting box 41 is pulled out When inside the fixed platform 1, the top wheel 45 will squeeze the wall of the fixed platform 1, so that the top wheel 45 drives the square block 46 to squeeze the elastic sheet 47 downward through the stabilizing rod 44, and the elastic sheet 47 is compressed.

During the maintenance process, the hydraulic cylinder can be rotated, and the nuts at different positions on the hydraulic cylinder can be disassembled, and the fixed shaft 33 is pushed to make the fixed shaft 33 pass through the rotating end circular hole of the hydraulic cylinder and collide with another fixed plate 34. The limit rod 38 limits The rotation of the gear 39 is limited, thereby limiting the rotation of the rotating disk 31, so that the hydraulic cylinder cannot rotate, avoiding slipping during the maintenance process. When the hydraulic cylinder needs to be rotated, the button 32 is pressed, the first spring 36 is compressed, and the wedge-shaped end of the button 32 will push the limiting rod 38 to move upward, and the second spring 37 will be compressed, thereby driving the bottom end of the limiting rod 38 and the gear 39 to disengage, and the rotating disk 31 can be rotated, thereby rotating the hydraulic cylinder. When one end of the fixed shaft 33 enters the other fixed plate 34, the rotation of the fixed shaft 33 is avoided under the restriction of the slide groove 71, and the fourth spring 72 pushes the ball 73 into the hemispherical groove 74, thereby limiting the movement of the fixed shaft 33. The filter 43 is pulled out intentionally to prevent the fixed shaft 33 from falling off during the rotation of the hydraulic cylinder. During maintenance, the waste hydraulic oil leaks out of the hydraulic cylinder, passes through the filter 43, and flows into the interior of the collection box 41. The groove 42 on the side wall of the collection box 41 is convenient for taking out the collection box 41; the groove 42 is pulled so that the groove 42 drives the collection box 41 to move back and forth in a small range. When the collection box 41 moves back and forth, the top wheel 45 will be squeezed with the arc block 49, so that the arc block 49 can be in continuous contact with the top wheel 45, and then the arc block 49 will drive the filter 43 to shake continuously, so that the oil stains attached to the filter 43 can be quickly cleaned into the interior of the collection box 41; The efficiency of cleaning the filter screen 43 is improved; when the rotating cover 22 is locked, the rotating cover 22 will push the pushing rod 63 to move downward, thereby pushing the connecting rod 64 to rotate, and the third spring 66 is compressed, so that the connecting rod 64 drives the locking rod 65 to move upward, so that the locking rod 65 and the locking groove 62 are disengaged, and the protective plate 61 can be opened to take out the maintenance tools, so as to avoid the loss of the maintenance tools when they are not being maintained.
