Description

Technical Field

[0001] The invention relates to the technical field of wire stringing, in particular to an automatic wire stringing tensioning device for electric wires on power line poles. Background Art

[0002] Stringing construction is the installation process of erecting overhead lines with connecting hardware and insulator strings on assembled poles and towers. Stringing construction is the completion stage of the transmission line construction project and the main process in the construction of overhead transmission lines. Its task is to erect the conductors and lightning conductors on the assembled poles and towers according to the designed stringing stress. Power line poles are composed of cement poles or metal poles, wires and electrical components that fix the wires. In the process of erecting power equipment, power line poles are one of the indispensable power equipment. When stringing power line poles, manual high poles are generally used to pull the wires. The staff needs to bind one end of the wire to the high pole, and then the staff will lift the wire to the top of the power line pole to install the wire.

[0003] Patent document with publication number CN118004843A discloses an automated wire-string tensioning device for electric wires on power line poles. The device passes a wire body through opposite ends of two guide wheels. When the outer side of the wire body is inserted into the gap between the two guide wheels, the wire body slightly pushes the two guide wheels outward, and the movement of the two guide wheels compresses and deforms the support spring. The deformed support spring clamps the wire body in the gap on the opposite sides of the two guide wheels, thereby maintaining a constant tension when the wire body is wound or unwound. When the wire body needs to be tensioned after being installed on the power pole, the motor is started by an external power supply, and the output end of the motor drives the winding roller to rotate, so that the wire body is wound around the winding roller, so that the wire is in a tensioned state. However, the device only controls the tension of the wire by the winding and unwinding of the winding roller, and the tensioning effect is general, thereby reducing the quality and efficiency of stringing the wires on the power line poles.

When the synchronization mechanism works, it can drive the first bevel gear 13 fixed to the rotating shaft 10 to rotate. Since the first bevel gear 13 is engaged with the second bevel gear 16, the cam 17 fixed to the rotating rod 15 is driven to rotate. At this time, the pull rod 18 can be pulled to swing and displace, and then the translation plate 20 can be pulled to move back and forth on the two concave rods 19, so that the wire body 4 in the rectangular frame 22 is evenly distributed on the retracting roller 3 when winding and tensioning, to prevent concentrated winding, ensure the smoothness during winding, and improve work efficiency.

[0028] like Figure 4 and Figure 5As shown: the guide mechanism includes a rectangular frame 22 fixedly connected to the upper end of the fixing frame 21, the upper end of the rectangular frame 22 is fixedly connected to a housing 23, the upper end of the housing 23 is inserted and rotatably connected to a handwheel rod 24, the inner end of the handwheel rod 24 is fixedly connected to a screw rod 25, a nut block 26 is threadedly connected to the screw rod 25, and the lower side wall of the nut block 26 is fixedly connected to two symmetrically arranged connecting rods 27, the lower ends of the two connecting rods 27 penetrate into the rectangular frame 22 and are fixedly connected to a concave plate 28, and the inner wall of the concave plate 28 is rotatably connected to the upper The guide roller 29 is located on the inner wall of the rectangular frame 22 below the upper guide roller 29 and is rotatably connected to the lower guide roller 30.

On the contrary, when the electric wire body 4 needs to be tensioned during the stringing process, the winding motor 7 is started to work in reverse, and the electric wire body 4 can be rewound to realize tensioning. Secondly, when the winding motor 7 is working, it can drive the driving wheel 9 on the driving shaft 8 to rotate. Since the driving wheel 9 is driven by the transmission belt 12 and the driven wheel 11, it can drive the rotating shaft 10 to rotate, realizing the work of the reciprocating transverse movement mechanism. One motor realizes the synchronous operation of two mechanisms, saving electricity and equipment costs, and having better working coordination.

At this time, the pull rod 18 can be pulled to swing and move, and then the translation plate 20 can be pulled to move back and forth on the two concave rods 19, so that the wire body 4 in the rectangular frame 22 is evenly distributed on the retracting roller 3 when winding and tensioning, to prevent concentrated winding, ensure the smoothness of winding, and improve work efficiency.

[0034] When the wire body 4 needs to be tensioned during the stringing process, the two electric push rods 32 are started to extend synchronously, which can push the two adjustment blocks 34 to move downward in the two slots 33, and then push the tensioning roller 35 to move downward to press the wire body 4 to achieve the tensioning effect, and cooperate with the retracting roller 3 to reel and tension the wire body 4, thereby improving the tensioning effect of the wire body 4 during the stringing process, and improving the stringing quality and efficiency of the power line pole;

[0035] Secondly, the handwheel rod 24 is rotated to drive the screw rod 25 to rotate. Since the screw rod 25 is threadedly connected to the nut block 26, the nut block 26 is forced to move downward, driving the concave plate 28 fixed to the connecting rod 27 to move downward, and the upper guide roller 29 and the lower guide roller 30 clamp the wire body 4 for positioning. The wire bodies 4 of different thicknesses can be clamped and guided. Compared with the spring structure, the clamping stability is stronger and the tensioning and conveying guidance is more precise.
