Traction conveying device for heavy wheeled vehicle

Abstract

The invention relates to a supporting, pulling and conveying device for a heavy wheeled vehicle, which comprises a base frame, a mast and a supporting arm, the base frame is mounted above a frame between two rear axle wheels at the tail of a rescue vehicle through a saddle, a turnover oil cylinder is mounted on the base frame, one end of the mast is connected with the base frame, and the other end of the mast is hinged with a telescopic rod of the turnover oil cylinder; the mast is driven by the overturning oil cylinder to move up and down and overturn, a lifting oil cylinder is installed at the upper end of the mast, the supporting arm is hinged to the lower end of the mast and hinged to a telescopic rod of the lifting oil cylinder, and the supporting arm is driven by the lifting oil cylinder to overturn. The supporting, pulling and conveying device controls movement and overturning actions of a mast and a supporting arm through mutual cooperation of an overturning oil cylinder and a lifting oil cylinder, and then supporting, pulling and conveying of a rescued vehicle are carried out. According to the invention, the potential safety hazard of tilting of the front axle of the rescue vehicle is eliminated, the stability of the supporting, pulling and conveying device is good, the heavy wheeled vehicle can be safely and quickly supported, pulled and conveyed, and the rescue efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a pulling and conveying device for heavy-duty wheeled vehicles. Background technique [0002] When a vehicle on the road fails to drive normally due to a malfunction or accident, in order to clear the road or send it to the factory for repair in time, it is usually necessary to use a wrecker to pull the faulty vehicle away from the roadway or send it back to the repair shop. At present, the existing wrecker-type lifting mechanism can only rescue small and light wheeled vehicles. If the faulty vehicle is a heavy-duty vehicle, due to the excessive load on its front axle, the use of the wrecker-type lifting mechanism for lifting will easily lead to the overloading of the rear axle of the rescue vehicle and the tendency of the front axle to tilt, resulting in insufficient adhesion. , there are safety hazards in steering during driving, such as figure 1 shown. SUMMARY OF THE IN...

Problems solved by technology

If the faulty vehicle is a heavy vehicle, due to the heavy load on the front axle, when the wrecker-type lifting mechanism is used for lifting and pulling, it is easy to cause the rear axle of the rescue vehicle to be overloaded, and the front axle tends to tilt, resulting in insufficient adhesion. , there is a potential safety hazard in steering during driving, such as figure 1 shown
