Description

Aerial working vehicle capable of automatically locking supporting legs Technical Field The utility model relates to the technical field of supporting legs, in particular to an overhead working truck capable of automatically locking supporting legs. Background The overhead working truck is a type of vehicle which is governed by a hydraulic or electric system and can be lifted up and down to perform work, and a constructor lifts off by the overhead working truck. A hydraulic or electric system is used for controlling a plurality of hydraulic cylinders, and a vehicle for performing work can be lifted up and down. The constructor lifts off with the aid of the overhead working truck. Overhead working vehicles are classified into scissor type, telescopic arm type, straight arm type, crank arm type and the like. However, the existing overhead working truck capable of automatically locking the supporting legs still has certain defects that the overhead working truck supports the supporting legs by means of a hydraulic system when in operation, but the hydraulic supporting system still has certain instability, and when the hydraulic system fails, the whole hydraulic supporting legs lose support, so that the overhead working truck deflects to one side, the overhead working truck tilts, and the accident is caused, so that the manpower and financial resources are lost. Disclosure of Invention The utility model aims to provide an overhead working truck capable of automatically locking supporting legs, so that after the hydraulic supporting legs are supported, a motor can drive a screw rod to enable a movable block to be matched with a limiting rod, and additional safety guarantee is further increased.
