Automobile lifter with safety device at front end

Abstract

The invention discloses an automobile lifter with safety device at the front end, which comprises an upright post, a lifting device, a lifting platform, a supporting arm and a safety device. The lifting device and the lifting platform are arranged inside the upright post; the supporting arm is connected with the lifting platform; the lifting device drives the lifting platform to lift; a plurality of safety inverted teeth are arranged at the front end of the upright post; the safety device is arranged on the lifting platform through a connecting plate and is provided with a safety hook; the safety hook is matched and clamped with the safety inverted teeth; the safety hook is arranged on the connecting plate through a rotating shaft connected with a shakable handle; the safety device is provided with an elastic piece; and the elastic piece props against the safety hook. The automobile lifter with the safety device at the front end has the advantages of simple structure, convenient maintenance, and capacity of improving the safety performance of the equipment on the basis of guaranteeing uniform and balanced stress of the safety device.

Description

technical field [0001] The invention relates to the field of lifting racks used for automobile maintenance, in particular to a front-mounted safety automobile lift. Background technique [0002] A car lift is a car repair machine used in the car repair industry. Car lifts play a vital role in car maintenance and repairs. Vehicle overhaul and maintenance are inseparable from hydraulic lifts. With the increase of automobile sales in our country, the demand for automobile lifts, as an important tool for automobile maintenance, has also greatly increased. The car lift is used to lift the car up and down during car maintenance, so that it is convenient for the repairman to repair the car. Since the car lift carries the weight of the car, and repairmen often work on the bottom of the car, the safety device of the car lift plays a vital role in the safety of the car lift. [0003] At present, the safety device of the car lift generally has the following two structures: one is th...

Problems solved by technology

[0003] At present, the safety device of the car lift generally has the following two structures: one is the built-in safety device, which is installed inside the column. The service life of the lift is greatly reduced, and due to the small space inside the column, it will be very difficult to maintain the safety device of the lift; the second is the rear-mounted safety, which can solve the problem of uneven force and difficult maintenance of the built-in safety Problem, but due to the limitation of the height of the column, the lifting platform of the lift must be raised to a certain height (60cm) before the rear safety can be used. When the lifting platform does not reach this height (60cm), it all depends on the lifting device, such as an oil cylinder The hydraulic system is self-locking, and its safety is unreliable. If the hydraulic system leaks, the lifting platform will automatically descend, which will cause certain dangers to the repair personnel.
