Abstract
The utility model discloses a rear support device of a road block removal truck. The rear support device is provided with a frame and a rear support trailing arm. The end of a vertical arm jacket is hinged with the frame, a vertical arm oscillating oil cylinder is disposed between the frame and the vertical arm jacket, a vertical arm is arranged in the vertical arm jacket, a height adjusting device is arranged between the vertical arm and the vertical arm jacket, the end of the vertical arm is hinged with the rear support trailing arm, one end of a folding oil cylinder is hinged with the rear support trailing arm while the other end is hinged with the vertical arm, and the end of the vertical arm is provided with a limiting block. The rear support device has the advantages of simple and stable structure, flexible action and capacity of adapting to work in various environments.
Description
Technical field
The utility model discloses the back support apparatus of a kind of road with wrecker.
Background technology
At present, along with the fast development of highway communication, the rapid increase of automobile quantity, the quantity of traffic accident is also in continuous increase, so the effect of road obstacle clearing vehicle is more and more outstanding.The manipulating object of wrecker, ground, operation place situation vary, and this just requires wrecker can deal with various situations.The butt trailing arm of existing road wrecker mostly is hinged on the vehicle support stand for front end, drive the butt trailing arm by hydraulic ram, whole butt trailing arm is rotated around interface point, accident vehicle is lifted or towing, and the butt trailing arm action of this structure is single, when being dragged vehicle " bad " on sloping road, when especially the gradient is big, or by lower, the angle of attach of holder vehicle chassis hour, all can not well finish the task of removing obstacles, there is certain limitation.
Summary of the invention
The purpose of this utility model is to provide a kind of back support apparatus of wrecker, and it has the characteristics of flexible movements, can solve the shortcoming that exists in the above-mentioned technology.
The technical scheme that realizes the utility model purpose is as follows:
The back support apparatus of wrecker, this device has vehicle frame and butt trailing arm, perpendicular arm overcoat end and vehicle frame are hinged, perpendicular arm swing oil cylinder is located between vehicle frame and the perpendicular arm overcoat, is provided with perpendicular arm in the perpendicular arm overcoat, is provided with arrangement for adjusting height between perpendicular arm and the perpendicular arm overcoat, perpendicular arm end and butt trailing arm are hinged, folding arm oil cylinder one end and butt trailing arm are hinged, and the other end and perpendicular arm are hinged, and perpendicular arm end is provided with limiting stopper.
Described perpendicular arm is a hollow tubular.
Described arrangement for adjusting height has leading screw, and leading screw is fixed in the perpendicular arm overcoat, and leading screw passes perpendicular arm and is threaded with perpendicular arm.
Adopted such scheme, when leading screw rotates in the perpendicular arm, because of perpendicular arm is connected with threads of lead screw, so the difference of the rotation direction of leading screw can drive the rise and fall of perpendicular arm, the folding arm oil cylinder makes the butt trailing arm along going out to rotate with perpendicular arm is hinged, the angle that limiting stopper restriction butt trailing arm rotates is excessive, maximum 90 °, perpendicular arm swing oil cylinder can make perpendicular arm overcoat and perpendicular arm drive the butt trailing arm along rotating with the vehicle frame hinged place, more than the rotation or the position adjustments of three kinds of modes, realized multi-aspect adjusting of the present utility model and rotation, flexible movements can adapt to the work of varying environment.
Useful benefit of the present utility model is a simple and stable structure, and flexible movements can adapt to the work of multiple environment.
