Problems solved by technology
However, this structure is limited by the length of the hydraulic cylinder. If the hydraulic cylinder is long, the hydraulic cylinder will be heavy, poor in structural stability, and high in cost; if the hydraulic cylinder is short, the large swing range of the curved mechanical arm cannot be realized. The adaptability of the system is poor

The present invention relates to wreckers. The wrecker includes a vehicle body platform and a lifting device arranged on the vehicle body platform. The lifting device includes a support arm whose bottom is hinged on the vehicle body platform. A support arm connecting seat, a supporting arm driving screw whose swing axis is parallel to the swing axis of the supporting arm is swingingly arranged on the vehicle body platform, and a threaded thread formed with the supporting arm driving screw is provided on the supporting arm connecting seat The thread transmission structure of the transmission fit; through the cooperation of the support arm connecting seat and the support arm driving screw, the swing angle of the support arm will be determined by the length of the support arm driving screw, compared with the hydraulic cylinder with limited length in the prior art , can drive the support arm to achieve a larger angle of swing, so as to achieve a larger operating range and good adaptability.
Description
technical field [0001] The present invention relates to wreckers. 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 wreckers to quickly remove obstacles and efficiently clean up construction waste. [0003] Existing wrecker such as application number is 201120231681.4, authorized announcement number is the earthquake disaster relief engineering vehicle disclosed by the Chinese patent of CN 202144279 U, comprises chassis, walking device and construction system, is hinged with mechanical arm on the chassis, and mechanical arm is supported by the mechanical arm shoulder. The joint motor is...
