A self-stabilizing device and self-stabilizing method for a 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] Technical Field The present invention relates to a crane, more particularly, to apparatus and auto-stabilization method for lifting from the transporter. Background technique [0002] Due to advances in hydraulics, electronics, high-strength steel and automotive industries, self-important, long working time to prepare mechanical drive truck crane has been replaced by hydraulic truck crane. Crane, also known lifting truck, mainly by lifting, luffing, revolving, and the vehicle chassis composition boom, in operation for an extended leg to be supplied from the stabilizing effect, the force of the vehicle passing through the leg to the ground, to ensure the safety and stability of the lifting truck work, having a good mobility, the advantage of rapid transfer. [0003] Conventional, such as China Utility Model Patent Publication No. CN204588547U patent application discloses a crane having a base and a crane thereof. Crane base, comprising: a lower leg member, a...

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
