Manual unlocking assembly of lifting machine

Abstract

The invention discloses a manual unlocking assembly of a lifting machine. The manual unlocking assembly of the lifting machine comprises fixed columns, wherein servo motors are arranged on the outer sides of the fixed columns; anti-drop holes are formed in the inner walls of the fixed columns; grooves are formed in the front surfaces of the fixed columns; the output ends of the servo motors are connected with driving gears; the outer surfaces of the driving gears are connected with chains; the position, near the lower parts of the driving gears, of the inner walls of the chains are connected with rotating gears; the position, near the lower parts of the rotating gears, of the inner walls of the chains is connected with driven gears; and control switches are arranged on the inner walls of the grooves, one sides of the grooves are connected with rotating doors, the inner sides of the rotating gears are connected with lifting arms, and springs are arranged at the bottom ends of the lifting arms. According to the manual unlocking assembly of the lifting machine, the control switches can be effectively hidden by arranging the grooves and the rotating doors, and the grooves are matched with the rotating doors, so that the problem of danger caused by misoperation of others or workers on the control switches is effectively solved.

Description

technical field [0001] The invention relates to the field of lifts, in particular to a manual unlocking assembly for lifts. Background technique [0002] Car lift refers to the car maintenance equipment used for car lifting in the car maintenance industry. Lifts play a vital role in vehicle maintenance and maintenance. No matter whether the vehicle is overhauled or minor repairs, it is inseparable from it. The nature and quality of its products directly affect the personal safety of maintenance personnel. [0003] However, in the lifts currently on the market, the control switches are all installed outside the device. When the staff is using the lift, other people or staff may accidentally touch the control switch, making the anti-falling structure of the device loose, resulting in dangerous situations, and The vibration force when the lifting arm is in contact with the ground cannot be effectively reduced, and the vibration force generated when the lifting arm falls will c...
