It is one or more insulated wire cores with a coating layer, a total protective layer and an outer protective layer. During power maintenance, wire and cable is an indispensable tool. Workers often need to carry some wire and cable on their bodies and then climb up the electric pole to work. At this time, it is necessary to select the appropriate type, specification and length of wire and cable and connect it to the circuit to be repaired.
[0003] A tractor for wire and cable is a device specially designed to pull wires, cables or optical fibers and other cables. These devices are used in power transmission, communication network construction, building construction and industrial production to pull the cables from one place to another, or install them on brackets, poles or pipes.
[0004] The current tractor places the wire and cable on the conveyor belt and uses a clamping device to drive it from one place to another. This device is only suitable for long-distance transportation on the ground. Therefore, a tractor for wire and cable is proposed to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: a tractor for wire and cable, including a base 1, a scissor strut 3 is slidably connected to the top of the base 1, a loading platform 2 is slidably connected to the top of the scissor strut 3, a first fixing plate 4 is fixedly connected to the rear side of the top of the loading platform 2, a first rotating shaft 5 is rotatably connected to the adjacent side of the two first fixing plates 4, a runner 6 is fixedly connected to the outer wall of the first rotating shaft 5, a limiting plate 7 is fixedly connected to the left and right ends of the runner 6, a blade 8 is fixedly connected to the front side of the top of the loading platform 2, and a fixing mechanism 9 is arranged on the top of the loading platform 2; saw teeth 15 are arranged on the top of the blade 8; a lifting cylinder 16 is fixedly connected to the top of the base 1.
[0031] Specifically, the base 1 provides stable support for the entire device, and the height of the device is controlled by the operation of the lifting cylinder 16 so that it can be adjusted next to the aerial operators. The first fixing plate 4 is connected to the rear side of the top of the loading platform 2, and its adjacent side is connected through the first rotating shaft 5, and the runner 6 is fixed on the outer wall of the first rotating shaft 5. In this way, the wire and cable can rotate on the runner 6, and limiting plates 7 are arranged on both sides of the runner 6 to prevent the wire and cable from running off or being caught by winding into other places. When the loading platform 2 rises next to the aerial operators, at this time, the cable is pulled to the required length and then cut to the appropriate length by the action of the blade 8.
[0032] Referring to Figure 3 , an embodiment provided by the present utility model: the fixing mechanism 9 includes two second fixing plates 901, the bottoms of the two second fixing plates 901 are fixedly connected to the top of the loading platform 2, a second rotating shaft 902 is rotatably connected to the upper middle parts of the two second fixing plates 901, grooves 907 are arranged on the adjacent sides of the two second fixing plates 901, a servo motor 903 is fixedly connected to the bottom of the loading platform 2, the output end of the servo motor 903 penetrates through the top of the loading platform 2 and is fixedly connected to a threaded rod 904, the outer wall of the threaded rod 904 is rotatably connected to the inside of the left groove 907, a fixing rod 905 is threadedly connected to the outer wall of the threaded rod 904, the right end of the fixing rod 905 is slidably connected to a support rod 906, and the outer wall of the support rod 906 is fixedly connected to the inside of the right groove 907.
[0033] Specifically, these two fixing plates II 901 are fixed to the top of the loading platform 2, and are provided with a rotating shaft II 902 and a fixing rod 905 at the bottom of the rotating shaft II 902. The wire and cable will pass through here and reach the hands of the high-altitude workers. The rotating shaft II 902 is rotatably connected to the fixing plate II 901, so that the wire and cable can slide through it. The bottom servo motor 903 controls the rotation of the threaded rod 904, and the threaded rod 904 and the fixing rod 905 at the right end jointly support the up and down movement of the fixing rod 905. When the specification of the wire and cable is large, control the operation of the servo motor 903 to make it move down. When it moves down to a suitable height, that is, when the wire and cable can be fixed between the rotating shaft II 902 and the fixing rod 905 and will not fall off, stop the operation of the servo motor 903. In this way, the normal operation of the device can be ensured when using wire and cables of different sizes, and the operation flexibility can be improved.
[0034] Referring to Figure 1 and Figure 2 An embodiment provided by the present utility model: Wheels 12 are provided at the bottom of the base 1, and a limiting rod 11 is rotatably connected to the outer wall of the wheels 12; A controller 10 is fixedly connected to the top of the loading platform 2; A push rod 13 is fixedly connected to the left side of the base 1; A handshake 14 is fixedly connected to the top of the outer wall of the push rod 13.
[0035] Specifically, hold the handshake 14 and push or pull the push rod 13, and move the device through the wheels 12. When it is necessary to fix the device, pull down the limiting rod 11, and the device will remain stable.
[0036] Working principle: The base 1 provides stable support for the entire device, and the height of the device is controlled by the operation of the lifting cylinder 16. The workers on the ground wind the wire and cable from the front side of the rotating wheel 6. After winding one circle, the wire and cable are stuck between the rotating shaft II 902 and the fixing rod 905. Start the lifting cylinder 16, and the loading platform 2 installed on its upper part is lifted by the lifting of the scissor strut 3. When it rises to the parallel height of the high-altitude workers, at this time, pull the wire and cable fixed between the rotating shaft II 902 and the fixing rod 905. At this time, the acting force makes the rotating shaft I 5 and the rotating wheel 6 outside the rotating shaft I 5 rotate, and the wire and cable also elongates accordingly. Then, it is cut by the blade 8 provided on the loading platform 2 to obtain the required length. And this rotating shaft II 902 is rotatably connected to the fixing plate II 901, so that the wire and cable can slide through it. The bottom servo motor 903 controls the rotation of the threaded rod 904, and the threaded rod 904 and the fixing rod 905 at the right end jointly support the up and down movement of the fixing rod 905. When the specification of the wire and cable is large, control the operation of the servo motor 903 to make it move down. When it moves down to a suitable height, that is, when the wire and cable can be fixed between the rotating shaft II 902 and the fixing rod 905 and will not fall off, stop the operation of the servo motor 903. In this way, the normal operation of the device can be ensured when using wire and cables of different sizes, and the operation flexibility can be improved.
