Self-stabilizing device and method for hoisting transport vehicle

Abstract

The invention relates to a self-stabilizing device and method for a hoisting transport vehicle. The self-stabilizing device comprises a supporting leg arm, wherein a hydraulic cylinder is arranged atone end of the supporting leg arm and connected with a supporting barrel; a chassis is arranged at the end, away from the hydraulic cylinder, of the supporting barrel; three supporting legs are rotationally arranged on the side wall of the supporting barrel; an auxiliary supporting plate is rotationally arranged at the ends, away from the supporting barrel, of the supporting legs; the supporting legs are connected with a contraction mechanism; a plurality of main base plates are arranged on the bottom face of the chassis; a plurality of auxiliary base plates are arranged on the bottom face ofthe auxiliary supporting plate; and The chassis and the main base plates, the auxiliary supporting plate and the auxiliary base plates, the main base plates and the main base plates, and the auxiliarybase plates are all fixed through fixing mechanisms. The supporting barrel is supported through the auxiliary supporting plate and the supporting legs, the stress area between the self-stabilizing device and the ground can be increased, and the self-stabilizing effect of the hoisting transport vehicle is improved; and the supporting legs are contracted through the contraction mechanism, and the width of the whole hoisting transport vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a self-stabilizing device for hoisting a transport vehicle and a self-stabilizing method thereof. Background technique [0002] Due to the advancement of hydraulic technology, electronics industry, high-strength steel and automobile industry, mechanical transmission truck cranes with heavy weight and long work preparation time have been replaced by hydraulic truck cranes. Truck cranes, also known as hoisting transport vehicles, are mainly composed of lifting, luffing, slewing, lifting arms and car chassis. When working, the outriggers must be extended to provide a self-stabilizing effect, and the force of the entire vehicle is transmitted through the outriggers. To the ground to ensure the safety and stability of the hoisting transport vehicle, it has the advantages of good maneuverability and rapid transfer. [0003] Existing ones, such as Chinese Patent Utility Model Patent App...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: due to the small force-bearing area of ​​the lower leg body, the greater the lifting weight required for hoisting the transport vehicle, the corresponding supporting area also needs to increase accordingly, so that the stability of the hoisting transport vehicle It can also be improved, but the vehicle width of the hoisting transport vehicle has a certain limit, the contact area between the lower leg body and the ground is limited, and the self-stabilization effect of the hoisting transport vehicle is not good
