wrecking car

Abstract

The invention relates to an obstacle destroying vehicle, which comprises a lifting device, wherein the lifting device comprises a mechanical arm and a mechanical arm support seat; the middle rear part of the mechanical arm is hinged to the mechanical arm support seat to swing up and down; a mechanical arm driving sliding block guided to move along a direction perpendicular to the swinging axis of the mechanical arm is arranged on the mechanical arm support seat; a mechanical arm connecting rod is hinged between the end part of the rear end of the mechanical arm and the mechanical arm driving sliding block; the mechanical arm connecting rod, the mechanical arm, the mechanical arm support seat and the mechanical arm driving sliding block form a crank-sliding block mechanism for enabling the mechanical arm to swing during the guided movement of the mechanical arm driving sliding block. According to the obstacle destroying vehicle, the mechanical arm can be driven by the crank-sliding block mechanism to swing during the guided movement of the mechanical arm driving sliding block, and because the movement range of the mechanical arm driving sliding block is determined by the guiding stroke, so that the swinging angle of the mechanical arm driven by the mechanical arm driving sliding block is larger than that of the mechanical arm driven by a length-limited hydraulic cylinder in the prior art, and larger operation range and high adaptability can be achieved.

Description

technical field [0001] The invention relates to an obstacle breaking vehicle. Background technique [0002] In recent years, natural disasters such as earthquakes, tsunamis, landslides, and mudslides have occurred frequently, often causing large-scale house collapses and casualties, which have brought huge losses to people. Reconstruction and rescue in disaster areas have become major issues that people need to face. In the process of disaster area reconstruction and disaster area rescue, it is often necessary to use a wrecking vehicle to quickly remove obstacles and efficiently clean up construction waste. [0003] Existing obstacle-breaking vehicle, such as application number 201120231681.4, authorized announcement number is the earthquake disaster relief engineering vehicle disclosed by the Chinese patent of CN 202144279 U, including chassis, running gear and construction system, and the chassis is hinged with a mechanical arm, and the mechanical arm is held by the should...

AI Technical Summary

Problems solved by technology

This structure can rely on a longer support arm to achieve a higher lifting height, but is limited by the length of the hydraulic cylinder. If the hydraulic cylinder is longer, the hydraulic cylinder will be heavy in weight, poor in structural stability, and high in cost; if the hydraulic cylinder is shorter , and the large swing range of the mechanical arm cannot be realized, and the adaptability of the construction system is poor

In addition, a longer robotic arm can easily lead to a higher center of gravity of the vehicle, which is not conducive to the long-distance transfer and stable operation of the vehicle
