Description

Small-size car cuts formula device of removing obstacles

Technical Field

The invention relates to the field of obstacle clearing machinery, in particular to a small vehicle shear type obstacle clearing device.

Background

The rush of motor vehicles causes traffic jam accidents caused by traffic congestion in cities and countryside to occur frequently. The automobile brings great convenience to work and life of people, but the traffic accidents caused by the automobile also bring endless troubles to people. In addition, the reasons for traffic congestion are: in the past, the urban construction lacks planning on motor vehicle parking places, particularly in public places with dense pedestrians and vehicles, and further lacks a large-scale parking place, so that the vehicles are parked in disorder and are prevented from normally running by pedestrians and vehicles; most roads in China are of a mixed structure, namely roads shared by pedestrians, non-motor vehicles and motor vehicles, some drivers are convenient for themselves for drawing, and park vehicles at will beside the roads to push the pedestrians and the non-motor vehicles to the center of the roads, so that the motor vehicles in normal running are blocked; vehicle collisions, roll-overs, etc. in traffic accidents. The wrecker can clear illegal parking and fault vehicles. Generally, vehicles forbidden to be parked are not arranged on a narrow road surface, a large traffic flow and a special road section, and some drivers park the vehicles on the road sections forbidden to be parked for one's own time, so that traffic jam or even traffic jam is caused. At present, the traditional domestic wrecker is mainly formed by modifying a second type of chassis, the volume is large, some working conditions are not completely suitable, for example, the function of timely rescuing can not be exerted in the road condition with traffic congestion, the existing wrecker is difficult to reach the scene in the congested road section or the road section with narrow and complex road condition, and the ordinary small transport vehicle can not timely and effectively clear the vehicle with the congested road section, so that the small vehicle scissor type wrecker is developed.

Detailed Description

The invention is further described with reference to the following figures and specific embodiments.

Example 1

As shown in figure 1, the small vehicle scissors type obstacle clearing device comprises a traction frame 1, a towing frame 3, towing arms 4, scissor arms, a hydraulic cylinder and a chassis frame 2, wherein each scissor arm comprises an inner scissor arm 5 and an outer scissor arm 7 hinged with the inner scissor arm 5, the towing frame 3 is hinged with the chassis frame 2 through the inner scissor arm 5, bases for mounting the towing arms 4 are arranged on two sides of the towing frame 3, the supporting arms are mounted on the bases, the lower end of the hydraulic cylinder is hinged with the chassis frame 2, the front end of the hydraulic cylinder is hinged with the scissor arms, the traction frame 1 is hinged with one end of the chassis frame 2 through a pin shaft, a slide way is arranged at the rear end of the towing frame 3 and matched with the outer scissor arms 7 to slide, universal wheels 8 are arranged on two sides of the front end of the chassis frame 2, driven wheels 6 are arranged on two sides of the rear end of the chassis frame 2, the towing frame 3 is U-shaped channel steel, the channel steel on the two sides is formed by connecting square steel. The structure of the scissor arm is shown in figure 2, and the connecting structure of the bracket 3 and the bracket arm is shown in figure 3.

When the hydraulic cylinder starts to work, the hydraulic cylinder is in a contraction state, the two front trailing arms 4 are unfolded, the pin shafts are inserted into the pin holes on the two sides, so that the trailing arms 4 do not rotate any more, and then the obstacle clearing device is pushed into the front bottom of a fault vehicle until the rear part of the fault vehicle

The trailing arm 4 can the level expand, inserts the round pin axle again, makes back trailing arm 4 no longer rotate, is fixed by trailer wheel and trailing arm 4, raises the pneumatic cylinder to the messenger is dragged by the trailer, makes trouble or vehicle violating the regulations drag away under miniature tractor's the traction. Preferably, the height of the towing bracket 3 is not more than 100mm when the hydraulic cylinder is fully contracted, so that the obstacle clearing device is ensured to be inserted into the bottom of a common car, and the height of the towing bracket 3 is 500mm when the hydraulic cylinder is fully extended, so that a towed vehicle is ensured to be towed. The low end of the hydraulic cylinder is hinged with the chassis frame 2, the front end of the hydraulic cylinder is hinged with the scissor arm, and the lifting of the bracket 3 is realized through the expansion of the hydraulic cylinder. The hydraulic cylinder adopts a double-hinged shear type structure, the two shear fork arms at each side of the hydraulic cylinder are connected through a pin shaft and can rotate mutually in a plane, one end of the inner shear fork arm 5 at each side is hinged with the towing bracket 3, the other end of the inner shear fork arm can slide on a track of the chassis frame 2, one end of the outer shear fork arm 7 at each side is hinged with the chassis frame 2, and the other end of the outer shear fork arm can slide in the track of the towing bracket 3; the hydraulic cylinder of the double-hinged shear type structure is obliquely arranged, one end of the hydraulic cylinder is fixedly hinged with the chassis frame 2, the other end of the hydraulic cylinder is hinged with the shear fork arm, and the hydraulic cylinder drives the piston rod to realize the lifting of the structure.

The chassis device is composed of a chassis frame 2, a front double universal wheel 8, a rear double driven wheel 6, a traction frame 1 and corresponding structural parts. The chassis frame 2 is a structure of considerable importance in the chassis device, and is determined according to a series of constraint factors such as a load borne by the whole structure, a use environment of the device, a structural form of the frame, a connection mode and the like. According to the stress condition of the vehicle frame, various impacts, forces in running and operation are finally transmitted to the vehicle frame, so that the vehicle frame has to have enough strength and rigidity to ensure the normal operation of the whole device. The frame is used as a base body of the chassis device and is simultaneously used for connecting the scissor arms and the lifting mechanism, and the frame is required to be compact and reasonable in structure so as to reduce the volume; the structure of the frame is ensured to be symmetrical as much as possible, and the influence on the running performance and the bearing capacity of the frame due to unbalanced weight is avoided.
