Abstract

The utility model relates to an S-shaped suspension arm mechanism for a road wrecker, which consists of a hoisting mechanism, a main hoisting arm, a telescopic hoisting arm, a telescopic hoisting arm oil cylinder, an amplitude oil cylinder, a swing arm oil cylinder, a secondary arm and a swing arm; the hoisting mechanism is arranged on the main hoisting arm through screw bolts, and the main hoisting arm is welded with the secondary arm as a whole; the telescopic hoisting arm is arranged inside the main hoisting arm through hinge pins, the telescopic hoisting arm is stretched out by the telescopic hoisting arm oil cylinder; the swing arm is connected with the secondary arm through hinge pins; the swing arm can be operated through the stretching movement of the swing arm oil cylinder, and the vehicles can be hoisted up by the hoisting fork by stretching the telescopic hoisting arm to the upper height of the vehicles to be hoisted. The S-shaped suspension arm mechanism has the advantages of simple structure, low cost, stable operation, convenient operation, reliable performance, independent action, reasonable structure, good integrity, strong hoisting ability and beautiful shape.

Description

Road obstacle clearing vehicle S type suspension arm mechanism

Technical field

The utility model relates to a kind of suspension arm mechanism of road obstacle clearing vehicle, particularly a kind of road obstacle clearing vehicle suspension arm mechanism of S type.

Background technology

At present, in the existing road obstacle clearing vehicle, to being used for urban highway, transport administration and settlement of accident, the wrecker that is used for bigger and heavier vehicle, it is very low generally to lift weight, has the problem that is difficult to guarantee the specific position handling, and globality and stability are bad in addition.

Summary of the invention:

Be to solve the problem that prior art exists, the utility model provide a kind of simple in structure, cost is low, operate steadily, easy to operate, rational in infrastructure, dependable performance, self contained function, good integrity, S type suspension arm mechanism that the ability of lifting is strong.

For achieving the above object, the novel technical scheme of taking of this use is: said road obstacle clearing vehicle S type suspension arm mechanism comprises hoisting mechanism, main arm, telescoping boom, telescoping boom oil cylinder, amplitude oil cylinder, swing arm oil cylinder, auxiliary, swing arm.It is characterized in that: hoisting mechanism is installed on the main arm with bolt, and main arm and auxiliary are welded into integral body; Telescoping boom is contained in the main arm with bearing pin, stretches by the telescoping boom oil cylinder, and telescoping boom is stretched out; Swing arm and auxiliary link together by bearing pin; By the flexible may command swing arm operation of swing arm oil cylinder, telescopic boom reaches by under the front overhang of holder vehicle, holds up vehicle by the holder fork.

This uses later-model good effect to be: but the utility model wrecker S type suspension arm mechanism is simple in structure, cost is low, stable, easy to operate, dependable performance self contained function, rational in infrastructure, good integrity, the ability of lifting are strong, and good looking appearance.

Description of drawings

Fig. 1 is that this uses later-model structural representation;

Fig. 2 is that the A that removes of swing arm is to view.

The specific embodiment

Be described further this use is novel in conjunction with the embodiments with reference to the accompanying drawings.

The utility model wrecker S type suspension arm mechanism is provided with hoisting mechanism 1 and is installed on the main arm 2 by bolt, and main arm 2 is welded into integral body with auxiliary 7; Telescoping boom 3 usefulness bearing pins are connected in the main arm 2, stretch by telescoping boom oil cylinder 4, and telescoping boom 3 is stretched out.Amplitude oil cylinder 5 is connected with main arm 2 usefulness bearing pins.Utilize amplitude oil cylinder 5 to stretch main arm 2 is carried out the adjustment of different angles, make it adjust to the optimum position, utilize hoisting mechanism folding and unfolding steel rope that the vehicle of different azimuth is drawn and handling.

Swing arm 8 and auxiliary 7 link together by bearing pin, and crossbeam and holder fork are installed on swing arm, and telescopic boom is reached by under the front overhang of holder vehicle, and swing arm oil cylinder 6 one ends utilize bearing pin to be installed in the auxiliary 7, and the other end is installed on the swing arm 8 with bearing pin.The flexible of swing arm oil cylinder 6 operated swing arm, promotes by swing arm vehicle is held up.
