Description

Technical Field

[0002] Lift, lifting work platform is a multifunctional lifting mechanical equipment, which can be divided into fixed and mobile, rail type, crank arm type, scissor type, chain type, loading and unloading platform, etc. Scissor lifts are divided into mobile scissor lifts and fixed scissor lifts; among which the mobile type is divided into traction type, self-propelled manual traction type and fully self-propelled type.

[0003] For example, a telescopic oil cylinder lift with the authorization announcement number "CN205419648U" is a lifting mechanism composed of an outer cylinder and a telescopic oil cylinder. It has a simple structure, strong stability, and flexible control. It can rise or fall smoothly. At the same time, through the multiple fixing devices, the vehicle can be better fixed for convenient maintenance. Through the external remote control, it can be remotely controlled. However, in this telescopic oil cylinder lift, the motor drives the electro-hydraulic combination mechanism to make the oil cylinder rise to the set height in sequence. Since the operator needs to adjust the height of the oil cylinder in sequence, it takes a long time to adjust the position of the oil cylinder, thereby reducing work efficiency. At the same time, when repairing other parts of the car, the operator needs to move back and forth around the maintenance vehicle. To repair the car, the operator moves back and forth, which consumes more physical strength of the operator, thereby increasing manual labor. Utility Model Content

[0026] Working principle:

[0027] When servicing a vehicle using a high-efficiency lift:

[0028] Preparation process:

[0029] The operator drives the vehicle to be repaired to the appropriate position of the workbench 5 through the pad 3, and then the operator starts the power supply of the four first hydraulic cylinders 8. The telescopic ends of the first hydraulic cylinders 8 extend to drive the limit plates 9 to approach the surface of the repair vehicle. Rubber pads are provided on the surfaces of the limit plates 9. When the rubber pads on the surfaces of the four limit plates 9 are tightly fitted with the surface of the repair vehicle, the repair vehicle is fixed. The rubber pads can prevent the repair vehicle from being damaged.

[0030] Lifting process:

[0031] The operator starts the power supply of motor 602, and the output shaft of motor 602 rotates forward to drive the threaded rod 603 to rotate, thereby driving the first slider 605 to move. The movement of the first slider 605 drives the second connecting rod 607 to move, thereby driving the first connecting rod 606 to move. The movement of the first connecting rod 606 drives the second slider 608 to slide along the slide groove processed on the top plate 609, thereby driving the top plate 609 to move upward. The upward movement of the top plate 609 drives the workbench 5 to move upward, thereby driving the maintenance vehicle to move upward. When the maintenance vehicle moves to the appropriate position, the power supply of motor 602 is turned off, the height of the vehicle can be quickly adjusted, and maintenance of the vehicle can be started, thereby improving work efficiency.

[0032] Repair process:

[0033] When it is necessary to repair other positions of the maintenance vehicle, the operator starts the power supply of the second hydraulic cylinder 202, and the output end of the second hydraulic cylinder 202 moves to drive the third slider 203 to move, thereby mobilizing the first boss 204 to slide along the slide groove processed on the roller 205, thereby driving the roller 205 to rotate, and at the same time the second boss 211 slides along the slide groove processed on the inner wall of the second shell 201, the rotation of the roller 205 drives the first gear 207 to rotate, thereby driving the second gear 208 to rotate, the rotation of the second gear 208 drives the rotating rod 209 to rotate, the rotation of the rotating rod 209 drives the first shell 601 to rotate, thereby driving the two rollers 7 to roll along the outer wall of the second shell 201, the two rollers 7 can support the first shell 601, and the rotation of the first shell 601 indirectly drives the maintenance vehicle to rotate. When the vehicle that needs maintenance is rotated to the other position in front of the operator, the power supply of the second hydraulic cylinder 202 is turned off to achieve the goal that the operator does not need to move back and forth, which can reduce the physical energy consumed by the operator. When the maintenance is completed, the operator starts the power supply of the second hydraulic cylinder 202, and when the maintenance vehicle is rotated to the same position as the initial position, the power supply of the second hydraulic cylinder 202 is turned off, and then the power supply of the motor 602 is started. The output shaft of the motor 602 is reversed, driving the top plate 609 to reset. When the top plate 609 is reset, the power supply of the motor 602 is turned off. Finally, the operator starts the power supplies of multiple first hydraulic cylinders 8. The output end of the first hydraulic cylinder 8 retracts, driving the limit plate 9 to reset. When the limit plate 9 is reset, the power supply of the first hydraulic cylinder 8 is turned off, and then the operator drives the repaired vehicle down from the surface of the workbench 5 along the surface of the pad 3.
