[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 - Figure 4 A tractor for electric wires and cables comprises a base 1 and two symmetrically arranged shells 2 installed on the base 1, a clamping conveyor belt 3 is installed in each of the two shells 2, a detachable handrail 4 is installed at one end of the base 1, and two symmetrically arranged slide grooves 101 are provided on the upper surface of the base 1, and sliders 5 are slidably connected in the two slide grooves 101, the two sliders 5 are fixedly connected to the two shells 2 respectively, a transmission assembly is connected between the two sliders 5, and both ends of the upper surface of the base 1 are connected to limit assemblies, and the two limit assemblies are located at the center line position of the base 1.

[0023] like Figure 1 - Figure 4 As shown, a wire and cable tractor in the utility model is similar to the existing wire and cable tractor structure, such as a wire and cable tractor disclosed in the patent publication No. CN219751464U. The main improvement of the utility model is that the wire and cable between the two conveyor belts 3 can be limited to prevent the wire and cable from being separated from the two conveyor belts 3 during the traction operation, thereby improving the stability of the traction operation. Figures 1 to 4As shown, when the wire and cable traction device in the utility model is in use, the wire and cable are passed through the two limit assemblies on the base 1, and the two sliders 5 and the two shells 2 are driven to move inward at the same time through the transmission assembly, and the two conveyor belts 3 are clamped on both sides of the wire and cable. When the wire and cable are pulled by the conveyor belt 3, the two ends of the wire and cable located above the base 1 are respectively restricted by the two limit assemblies, thereby preventing the wire and cable from moving up and down, and then detaching from the top between the two conveyor belts 3, thereby improving the stability of the wire and cable traction operation.

[0024] like Figure 1 - Figure 4 As shown, the limiting assembly includes a support rod 8 and a limiting cover 9, the support rod 8 is fixedly connected to the base 1, and a placement hole 801 is provided through the side wall of the support rod 8 away from the base 1, one side of the limiting cover 9 is hinged with one side of the support rod 8 by a hinge, and a locking piece is connected to the side of the support rod 8 away from the hinge, and the locking piece is connected to the side of the limiting cover 9 away from the hinge. When using the limiting assembly, first open the limiting cover 9 from the support rod 8 through the hinge, then place the wire and cable in the placement hole 801 of the support rod 8, and place the other end in the placement hole 801 of another support rod 8 by the same operation, then cover the placement hole 801 above the support rod 8 and lock it through the locking piece, at this time, the wire and cable are fixed in the placement hole 801, and when the traction operation is performed, the two ends of the wire and cable above the base 1 can be located in the placement hole 801, thereby preventing the wire and cable from moving upward or downward, and preventing the wire and cable from being separated from between the two conveyor belts 3, ensuring the smooth progress of the wire and cable traction operation.

[0025] like Figure 3 and Figure 4 As shown, the locking member includes an L-shaped elastic lock hook 10, one end of the long rod of the L-shaped elastic lock hook 10 is fixedly connected to the side of the support rod 8 away from the hinge, and a lock groove 901 is provided on the side of the limit cover 9 away from the hinge, and the end of the L-shaped elastic lock hook 10 away from the support rod 8 is plugged into the lock groove 901. The limit cover 9 is covered above the placement hole 801 of the support rod 8, and the L-shaped elastic lock hook 10 is hooked in the lock groove 901 of the limit cover 9, so that the limit cover 9 is fixed above the support rod 8 to complete the position fixation of the wires and cables. The L-shaped elastic lock hook 10 needs to have a certain elastic deformation so that it can be hooked into the lock groove 901 to complete the fixation of the limit cover 9.

[0026] like Figure 3 and Figure 4As shown, the end of the L-shaped elastic lock hook 10 close to the lock slot 901 is provided with an inclined surface, and the inclined surface abuts against the limiting cover 9. When the limiting cover 9 flips downward, the end abuts against the inclined surface of the L-shaped elastic lock hook 10, so that the L-shaped elastic lock hook 10 is squeezed outward and deformed by the inclined surface. As the lock slot 901 moves, the L-shaped elastic lock hook 10 rebounds and can automatically hook into the lock slot 901, completing the fixing of the limiting cover 9, which is more convenient to use.

[0027] like Figure 1 - Figure 4 As shown, the placement hole 801 is a semicircular groove, the limiting cover 9 is a semicircular cover, and the limiting cover 9 cooperates with the placement hole 801 to form a circular hole. The placement hole 801 cooperates with the limiting cover 9 to form a circular hole, which better matches the wires and cables and reduces the friction and scratching between the wires and cables and the placement hole 801 and the limiting cover 9.

[0028] like Figure 1 - Figure 4 As shown, the circular hole formed by the placement hole 801 and the limit cover 9 is located at the center line of the conveyor belt 3. When the wires and cables are placed on the support rods 8, the wires and cables are located in the middle of the two conveyor belts 3. When the conveyor belt 3 pulls the wires and cables, the wires and cables between the two support rods 8 are located at the center line of the conveyor belt 3, so that when the wires and cables swing up and down, they swing up and down at the center line of the conveyor belt 3, which can avoid being separated from the conveyor belts 3, making the pulling operation more stable.

[0029] like Figure 1 and Figure 2 As shown, the transmission assembly includes a transmission motor 6 and a bidirectional threaded rod 7, the transmission motor 6 is fixedly connected to one side of the base 1, the output shaft of the transmission motor 6 is fixedly connected to the bidirectional threaded rod 7, the end of the bidirectional threaded rod 7 away from the transmission motor 6 passes through two slide grooves 101 and two sliders 5 at one time, and is rotatably connected to the inner wall of the slide groove 101 away from the side of the transmission motor 6, and the bidirectional threaded rod 7 is threadedly connected to the two sliders 5. By starting the transmission motor 6, the bidirectional threaded rod 7 is driven to rotate, thereby simultaneously driving the sliders 5 on both sides and the housing 2 to move closer to or away from each other, and the adjustment is more stable, ensuring that the conveyor belts 3 on both sides can clamp the wires and cables in the middle position without offset.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
