How to lift and repair a car

Abstract

The invention discloses a method for jacking and maintaining an automobile, which comprises the following steps: (1) a user places the device directly below the heavy object to be lifted and the weight is arranged on the upper end surface of the upper supporting seat; (2) a motor runs and transmits power to a screw rod through a power transmission mechanism, and the screw rod rotates in the axialdirection of the screw rod under the power provided by the motor; (3) the screw rod rotates in the axial direction of the screw rod and makes a driving block move close to a fixed block along the axial direction of the screw rod, so that the lifting device is switched from the contracted state to the extended state, and the weight rises to the highest point; (4) after the lifting device is used, the motor reversely runs to make the screw rod rotate reversely, so that the lifting device is switched from the extended state to the contracted state, and the upper supporting seat is then restored to the initial state, namely, the lifting device is restored to the initial state.

Description

technical field [0001] The invention relates to a method for lifting and lowering heavy objects. Background technique [0002] The jack is a commonly used tool in the maintenance of vehicles. Commonly used jacks generally use mechanical or hydraulic methods to drive the jack up and down to lift the vehicle. However, mechanically driven jacks require personnel to keep shaking the joystick to lift the vehicle. , Time-consuming and labor-intensive, while the structure of the hydraulically driven jack is relatively complicated, and the manufacturing cost of the jack is relatively high. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a method for lifting heavy objects to solve the problems mentioned in the above background. This equipment makes the process of lifting the heavy objects smooth and smooth, and the lifting device in this equipment There are four sets to balance the lifting fo...
