Safety trolley for automobile chassis maintenance

Abstract

The invention discloses a safety trolley for automobile chassis maintenance. The safety trolley for automobile chassis maintenance comprises a flat plate type trolley body, a sliding plate is movablyarranged on the top surface of the flat plate type trolley body, the four corners of the top surface of the flat plate type trolley body are provided with the same fixing sleeves correspondingly, liftable supporting columns are arranged in the fixing sleeves, a head supporting plate which extends backwards is formed in the center of the rear end surface of the flat plate type trolley body, a bending mounting frame is fixed to the center of the bottom surface of the flat plate type trolley body, a horizontal air cylinder is fixed to the front end surface of a vertical plate of the bending mounting frame, and a piston rod of the horizontal air cylinder is connected to a downwards-extending vertical portion arranged at the front end of the sliding plate. The safety trolley has the advantagesthat the safety trolley is provided with the four liftable supporting columns so that an automobile can be abutted on the periphery of a human body, an emergency situation of sudden descending of an automobile body can be prevented, moreover, a person can be conveyed out of the automobile bottom in a short time through the action of the air cylinder to be quickly separated from the dangerous automobile, and the absolute safety of the personnel can be ensured.

Description

technical field [0001] The invention relates to the field of automobile maintenance equipment, in particular to an automobile chassis maintenance safety trolley. [0002] Background technique: [0003] The most important link in car repair is the inspection and maintenance of the car chassis, and the car chassis is not easy to observe. Therefore, it is often necessary to use a crane to lift the car for a certain distance during the repair process, and then the staff will lie on it again. Only the bottom of the car can be operated easily. Because people are under the car, the potential safety hazards cannot be ignored. The current maintenance method is that people lie directly on the bottom of the car or lie on a flatbed to enter the bottom of the car, and these two methods are not available. A certain protective effect, once an accident occurs, it will often cause incalculable consequences. [0004] Invention content: [0005] The purpose of the present invention is to addr...
