Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a trailer mechanism for a road obstacle removing vehicle comprises a supporting truss I1, wherein two sides of the top end of the supporting truss I1 are respectively and fixedly provided with a supporting truss II 3 through connecting bolts 2, the back face between the supporting truss II 3 and the supporting truss I1 is in transmission connection through a lifting mechanism 4 connecting rod, supporting wheel sets 5 are fixedly arranged on two sides of the top end of the supporting truss I1, two sides of the supporting truss I1 are respectively and fixedly provided with an adjusting mechanism 6 in threaded connection, and one end of the adjusting mechanism 6, which is located in an inner cavity of the supporting truss I1, is movably connected with a supporting curved surface 7.

Wherein, to the setting of support truss I1, support truss II 3 and lifting mechanism 4, combine the weight of vehicle self to make support truss I1 receive decurrent effort, utilize lifting mechanism 4's connecting rod transmission structure to push down support truss II 3 simultaneously, and then exert reverse effort and lift the tire of vehicle off the ground to support truss I1, can utilize this trailer mechanism of four groups to come the whole ground of four groups of tires of vehicle off simultaneously, in order to drag the vehicle of violating the rule away under the circumstances of not rotating the tire, in order to ensure under the circumstances of uncertain vehicle driving wheel group, the effectual vehicle of violating the rule away of safety and stability is dragged away, and can not construct the damage to its driving machine.

In this technical scheme, adjustment mechanism 6 includes adjusting screw 61, adjusting screw 61's surface and the internal thread connection of supporting truss I1, and adjusting screw 61's one end fixed mounting has adjusting plate 62, and adjusting plate 62's surface and the inside swing joint of supporting curved surface 7, and adjusting screw 61's other end fixed mounting has regulation runner 63.

Wherein, to adjustment mechanism 6's setting, when facing not automobile tire of equidimension, the interval between two sets of support curved surfaces 7 of adjustment that can be nimble for the joint that the cambered surface structure of supporting curved surface 7 can be stable is on the surface of vehicle tire, makes its phenomenon that can not take place to rock lifting away the in-process, has good suitability and stability.

In this technical scheme, the outside of adjusting clamp plate 62 is equipped with type structure, and one side of adjusting clamp plate 62 type structure is equipped with the arc structure.

In this technical scheme, the outside of supporting curved surface 7 is equipped with the arc structure, and is equipped with the type-convex spout the same with the external structure of adjusting the clamp plate 62 in the inside of supporting curved surface 7.

Wherein, to the setting of adjusting the clamp plate 62 outer structure and supporting the curved surface 7 inner structure, when facing the lower vehicle in ground clearance for supporting curved surface 7 can slide along adjusting the track of clamp plate 62, and then adjusts the maximum height in two sets of supporting curved surfaces 7, makes it can not touch the chassis of vehicle when lifting away from the tire, provides stable effectual holding power to the vehicle tire simultaneously, can not take place to slide the phenomenon that drops because of the vehicle overweight.

In the technical scheme, the projection position of the highest point of the lifting mechanism 4 is located in the area of the top end of the support truss II 3.

The arrangement of the highest point projection position of the lifting mechanism 4 can effectively avoid the phenomenon that the vehicle is damaged due to the fact that the connecting rod of the lifting mechanism 4 is too long and collides with the surface of the vehicle when the lever principle is utilized to easily and conveniently lift the tire of the illegal vehicle off the ground, and the reliability of the trailer mechanism is further improved.

The use method and the working principle of the embodiment are as follows:

when the vehicle faces an illegal vehicle, firstly, two groups of adjusting rotating wheels 63 are respectively rotated to adjust the distance between two groups of supporting curved surfaces 7 under the action of screw thread transmission between an adjusting screw rod 61 and the inner part of a supporting truss I1, then the two groups of supporting curved surfaces 7 are respectively moved to two sides of a vehicle tire, simultaneously, under the action of mutual movable clamping between an adjusting pressure plate 62 and the inner part of the supporting curved surfaces 7, the two groups of supporting curved surfaces 7 are downwards pulled to be positioned at the positions which are lower than the two sides of the vehicle tire, the adjusting rotating wheels 63 are reversely rotated again to drive the two groups of supporting curved surfaces 7 to be tightly attached to the surface of the vehicle tire, then a downwards lifting mechanism 4 is upwards pulled, and as the supporting truss I1 bears all the weight of the vehicle, in the process of rotating the lifting mechanism 4, the supporting truss II 3 and a supporting wheel set 5 fixedly arranged on the supporting truss II 3 gradually move downwards, and then under the action of the link drive in the lifting mechanism 4, the vehicle tires tightly attached between the two groups of supporting curved surfaces 7 are lifted off the ground, and meanwhile, the four groups of tires of the vehicle are completely lifted by repeating the steps so as to ensure that the tires cannot rotate when the vehicle is dragged, so that the driving mechanism of the vehicle is effectively protected from being damaged under the condition that the driving wheel set of the vehicle is not determined, and finally, the traction mechanism on the road wrecker is utilized to drag the illegal vehicle to the carriage of the illegal vehicle to move away.
