Description

Technical Field

[0001] The present application relates to the field of power transmission and transformation line installation, and more specifically, to a power transmission and transformation line installation traction device. Background Art

[0002] The power transmission and transformation line is the circuit used by the power plant to transmit electricity to the power grid. Due to the large mass of the cable, the power transmission and transformation line needs to be pulled by a traction device when laying the cable. The patent document with the prior art publication number CN216272385U provides a power transmission and transformation line conductor traction device. The device is provided with a motor arranged in a motor box, a first gear on the front side of the outer wall of the main shaft, a second gear in the middle of the outer wall of the main shaft, a transmission belt on the outer wall of the roller and a conveyor belt on the outer wall of the transmission belt. The cooperation between the motor and the second gear drives the transmission belt, so that the staff does not need to manually release the wire during the wire traction process, and can straighten the bent wire while releasing the wire and pulling it at the same time, which not only reduces the work intensity of the staff, but also improves the efficiency of wire traction.

[0003] With respect to the above-mentioned related technologies, the inventor believes that since the two conveyor belts are arranged at a fixed interval, it is difficult to adapt cables of different sizes, the applicable scenarios are limited, and the practicality is poor. Therefore, we propose a traction device for installing a power transmission and transformation line. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, the present application provides a traction device for installing a power transmission and transformation line.

[0005] The present application provides a traction device for installing a power transmission and transformation line, which adopts the following technical solution:

[0006] A traction device for installing a power transmission and transformation line comprises a base, a plurality of guide wheels A are rotatably connected to the base, a slide seat is slidably connected to the base, a plurality of guide wheels B are rotatably connected to the slide seat, the guide wheels A and the guide wheels B cooperate to clamp cables, a motor is fixedly mounted on the base, the motor is transmission-connected to a guide wheel A, two U-shaped plates are fixedly connected to the base, two limit plates are elastically connected to both sides of the slide seat, one end of the limit plate and one side of the U-shaped plate are provided with the same slot, and the limit plate is snap-fitted with the U-shaped plate.

[0007] By adopting the above technical solution, the slide seat can be slid up and down on the base to change the distance between guide wheel A and guide wheel B. When guide wheel A and guide wheel B are in close contact with the cable, the slide seat can be limited by sliding to abut against the U-shaped plate through the limit plate. At this time, after the motor drives guide wheel A to rotate, guide wheel A and guide wheel B cooperate to pull and transport the cable.

[0008] Optionally, the plurality of guide wheels A and the plurality of guide wheels B are linearly arranged at equal intervals, and the guide wheels A and B are provided with anti-slip grooves.

[0009] By adopting the above technical solution, multiple guide wheels A and multiple guide wheels B are in direct contact with the cables, avoiding the reduction of friction due to deformation of traditional conveyor belts during travel, and the setting of anti-slip grooves can further increase the stability of contact with the cables.

[0010] Optionally, the output end of the motor is connected to a guide wheel A through a chain, and two adjacent guide wheels A are connected through a chain transmission.

[0011] By adopting the above technical solution, multiple guide wheels A can achieve synchronous rotation in the same direction through the cooperation of chains. After the guide wheel A cooperates with the guide wheel B to tightly clamp the cable, the guide wheel A rotates to pull the cable.

[0012] Optionally, the limit plate is slidably connected to the slide seat, and two adjacent limit plates are elastically connected via a spring A.

[0013] By adopting the above technical solution, the slot of the limit plate and the slot of the U-shaped plate are arranged oppositely. When the spring A is not subjected to external force, it drives the limit plate and the U-shaped plate to abut against each other, so that the two slots are engaged with each other, and the slide seat cannot slide upward.

[0014] Optionally, two positioning plates are slidably connected to both sides of the slide seat, and two limit plates of the positioning plates are abutted and matched.

[0015] By adopting the above technical solution, after the positioning plate is lowered to abut against the two limiting plates, the two limiting plates can be prevented from approaching each other, thereby achieving stable contact between the limiting plate and the U-shaped plate.

[0016] Optionally, a plurality of springs B are elastically connected between the U-shaped plate and the slide seat.

[0017] By adopting the above technical solution, when the limit plate is not in contact with the U-shaped plate, the spring B can shrink and reset to drive the slide seat to rise, so as to increase the distance between the guide wheel B and the guide wheel A.

[0018] Optionally, telescopic rods are fixedly connected to both sides of the base, and one end of the telescopic rods is fixedly connected to a limiting ring.

[0019] By adopting the above technical solution, the telescopic rod can be adjusted in height, so that the cable can pass through the limiting ring. The limiting ring limits the cable to prevent it from detaching, thereby further improving stability.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The slide can be lifted and slid to adjust the distance between the guide wheel B and the guide wheel A, so that it can be adjusted according to the size of different cables. When the slide is adjusted to the right position, the spring A automatically drives the limit plate to engage with the U-shaped plate, so that the guide wheel A and the guide wheel B cooperate to clamp the cable tightly. It is easy to operate and has a wide range of applications.

[0022] 2. Multiple guide wheels A and multiple guide wheels B cooperate to directly contact the cables, and the protective patterns are set to increase the friction when in contact with the cables, thereby avoiding slipping and improving the traction effect. BRIEF DESCRIPTION OF THE DRAWINGS
