Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a traction hook displacement device. Background Art

[0002] The rigid traction device (hereinafter referred to as rigid traction) is the intermediate connection device between the tractor (trailer) and the faulty vehicle. The rigid traction uses its own rigidity to constrain the direction of the faulty vehicle, so that the faulty vehicle follows the tractor in a predetermined direction. The tractor can move forward, stop suddenly, reverse, turn, climb, turn uphill, go downhill, turn downhill, and make a U-turn through the rigid traction.

[0003] The rigid traction mainly includes two traction rods, which can be divided into single-point connection and double-point connection according to different connection methods. The currently known rigid traction rods are integral rigid parts. When the tractor and the faulty vehicle are connected by double-point connection, the positioning accuracy of the tractor is high, and the tractor needs to be repeatedly shifted and positioned to complete the installation. Sometimes the installation cannot be completed due to the influence of terrain, etc. The entire installation process is not only difficult, time-consuming, and inefficient, but also greatly increases the labor intensity of the operators. In addition, when the tractor makes a big turn in the double-point connection method, the rigid traction rod is subjected to great force, and there is a risk of the rod bending.

[0004] The currently known rigid-traction connection methods are mainly limited by the number of traction seats in front of the cab of the faulty vehicle. An optimized design is to install a traction hook displacement device on the front side of the faulty vehicle to change the rigid-traction connection method from a double-point connection to a single-point connection. The device is connected to the faulty vehicle in an articulated manner, which increases the convenience of installation to a certain extent and fundamentally changes the rigid-traction connection method. However, there are still areas that need to be improved: due to the different spacing between the double traction seats on the front side of different faulty vehicles and the different angles of the two ears of the traction seats, the traction point and direction of the traction hook displacement device are required to have a certain degree of adjustability. Summary of the invention

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a towing hook displacement device with a simple structure and good effect.

[0006] The utility model is realized by the following technical scheme: a traction hook displacement device comprises a rod body, a fixed seat is fixed at the middle position of the rod body, a traction hook is connected to the fixed seat, sliding seats I and II are respectively arranged on both sides of the fixed seat, the sliding seats I and II are connected to the rod body through threads, connecting rings I and II are respectively connected to the sliding seats I and II, a left fixing ring and a right fixing ring are respectively arranged at the two ends of the rod body, and springs are arranged at the intervals between the left fixing ring, the sliding seat I, the fixed seat, the sliding seat II and the right fixing ring.

[0007] It is further provided that: the fixing seat is welded on the rod body.

[0008] The traction hook is welded on the fixing seat.

[0009] The connecting ring I and the sliding seat I are welded together with a rib plate provided therebetween, and the connecting ring II and the sliding seat II are welded together with a rib plate provided therebetween.

[0010] The fixing angles of the connecting ring I and the connecting ring II match the traction seat of the faulty vehicle.

[0011] The left fixing ring and the right fixing ring are connected to the rod body through threads.

[0012] The left fixing ring and the right fixing ring are limited by R-shaped clips and pins arranged at both ends of the rod body.
