[0002] A tractor is a kind of industrial equipment and is often used at various construction sites. There are various types of tractors. Among them, the tractors used in some cable lines are used to drag the conductors of power lines or communication lines from the ground to the track for easy laying and maintenance. The cable tractor plays an important role in the construction of electric wires and cables, especially in the construction of power and post and telecommunications lines for erecting poles or motorized wire laying, as well as in hoisting and towing heavy objects at places such as buildings and docks. This equipment is suitable for places without electricity in the wild, is flexible to use, has a small volume and is flexible and convenient to use, and is more suitable for use in narrow roads, especially for cable construction in cities. In addition, the cable tractor can also be used for operations such as tight wire and pole erection, and is the first choice tool for the erection of power and communication electric wires and cables, especially for urban cable construction. Therefore, there is a particular need for a traction control device for a tractor.

[0003] For the existing traction control device of a tractor, most tractors use upper and lower sets of conveyor belts to tow the cable. Usually, the conveyor belts are parallel and in a flat form. When contacting the cable, the friction force is small, which easily causes the part of the towing belt to be unable to convey the cable during the towing process. Content of the Utility Model

Usually, the conveyor belts are parallel and in a flat form. When contacting the cable, the friction force is small, which easily causes the part of the towing belt to be unable to convey the cable during the towing process as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A traction control device for a tractor includes a base. A first conveyor belt is fixedly installed above the base. A second conveyor belt is arranged above the first conveyor belt. One end of the second conveyor belt is provided with a belt.

[0022] Furthermore, the surface of the belt 4 at one end of the second conveyor belt 3 close to the first conveyor belt 2 is arc-shaped. The arc-shaped plate 6 and the support blocks 7 are integrated with the belt 4 and are both made of rubber. Through the settings of the arc-shaped plate 6, the support blocks 7 and the belt 4, when the first conveyor belt 2 and the second conveyor belt 3 come into contact, since the lower part of the belt 4 of the second conveyor belt 3 is arc-shaped, when in contact, the corresponding surface of the belt 4 will be entirely arc-shaped, so that the cable will also be in an arc shape during the traction process. The arc-shaped structure is more stable and has stronger friction than the conventional planar structure during transportation.

[0023] Furthermore, both the first conveyor belt 2 and the second conveyor belt 3 are provided with belts 4 and have the same internal structure. Through the setting of the belt 4, when the belt 4 is squeezed by the cable, the arc-shaped plate 6 in the middle will have a certain depression, and the support blocks 7 on both sides will squeeze towards the middle, so that the contact surface between the belt 4 and the cable is larger.

At the same time, the cable remains straight when passing through the first pipe-passing plate 804 and the second pipe-passing plate 808. The two ends of the first pipe-passing plate 804 and the second pipe-passing plate 808 are combined into a conical structure, which is convenient for the cable to pass through. Moreover, the first spring 803 and the second spring 807 can play a good buffering role, preventing the excessive extrusion force on the cable from affecting the smoothness of the traction process.

A second threaded rod 903 penetrates through one end of the movable groove 902. One end of the second threaded rod 903 is connected with a fixing nut 904. One end of the second threaded rod 903 penetrates through a fixing plate 905. Both ends of the fixing plate 905 are welded with connecting plates 906. Third threaded rods 907 are fixedly installed at both ends of the connecting plates 906. One end of the third threaded rod 907 penetrates through a concave plate 908. A connecting block 909 is arranged below the concave plate 908. A third spring 910 is arranged on the outer ring of the third threaded rod 907.

The concave plate 908 is fixedly connected with the second conveyor belt 3. Through the setting of the concave plate 908, both ends of the concave plate 908 can be fixedly connected with the second conveyor belt 3, and then the concave plate 908 can be buffered by the third spring 910.

[0028] Working principle: First, one end of the cable is inserted through the middle of the first pipe-passing plate 804 and the second pipe-passing plate 808. Then, the first threaded rod 809 is rotated on one side of the clamping plate 806 to connect the first threaded rod 809 with the threaded hole 805, and the clamping plate 806 is fixed to one end of the bottom plate 802. Subsequently, the cable is passed through the middle of the first conveyor belt 2 and the second conveyor belt 3, and then through the middle of the first pipe-passing plate 804 and the second pipe-passing plate 808 at the other end of the base 1. Then, according to the size of the cable, the position of the fixed plate 905 is moved on one side of the support plate 901 to adjust the height of the second conveyor belt 3. Subsequently, the second threaded rod 903 is penetrated through one end of the movable groove 902, the second threaded rod 903 penetrates through the fixed plate 905, and the fixed plate 905 is locked by the connecting fixing nut 904. Secondly, the locking nut 911 is rotated to adjust the pressure of the third spring 910. After the adjustment is completed, the first conveyor belt 2 and the second conveyor belt 3 are started. During the conveying process, the first conveyor belt 2 and the second conveyor belt 3 exert extrusion on the cable, and a certain depression will be formed at the extrusion point, increasing the contact area between the belt 4 and the cable, so as to stably traction the cable.
