Automatic pull wire sag controller

Abstract

The invention discloses an automatic pull wire sag controller comprising a motor base, a motor, a paddle, a guide shaft, a guide rod, a spring, an adapter male head, an adapter female head, a gear, a rack, a gear fixing bearing, a thrust bearing, a press plate and an eccentric clutch, wherein the left end of the guide shaft is inserted into a guide shaft mounting hole in the paddle, and connected with an output shaft of the motor; the left end of the guide rod is inserted into a guide rod mounting hole of the paddle; the eccentric clutch is arranged at the right end of the guide rod, and a clutch handle is arranged on the eccentric clutch; and the spring, the adapter male head, the adapter female head, the gear, the gear fixing bearing and the thrust bearing are sequentially sleeved on the guide shaft from left to right. According to the automatic pull wire sag controller provided by the invention, the wire is automatically taken up or paid off by controlling sag, so that nondeterminacy of manual control is avoided, automatic control is achieved, construction intensity is reduced, efficiency of electric wire stringing construction is improved, and security of electric wire stringing construction is ensured.

Description

technical field [0001] The invention relates to an automatic sag controller of a traction line. Background technique [0002] The traditional method of laying out lead wires in electric power construction is mainly completed by construction personnel manually operating traditional mechanical equipment such as tension machines and tractors. During specific operations, it is necessary to place the lead wire reel in the tension field and deploy it to the traction field by manpower. When unfolding, the lead ropes pass through the pay-off blocks of each pole tower in the line erection section in turn, and the two ends are respectively anchored in the tension field and the traction field for pulling and releasing the traction rope. Loosen the lead rope anchored in the traction field, connect it with the traction rope wound on the small tension machine with a rotary connector, and pull it to the tension field with the small traction machine placed in the tension field. The traction...

Problems solved by technology

[0004] When using an unmanned aircraft for setting-out operations, due to the large construction span, the traction line will encounter situations where the sag of the traction line cannot be perfectly controlled, causing the traction line to collide with natural objects on the ground, ground buildings, and underlying facilities, such as crossing Roads, railways, rivers, underlying power facilities, and traction lines are in contact with them, resulting in dangerous accidents and endangering the safety of the ground and setting-out construction

[0005] Take the 50-meter-wide highway as an example: the unmanned aircraft must first pull the first-level lead (due to the limitation of the aircraft lift, it can only be equipped with 2mm-5mm high-strength rope) from one side of the road to the other side of the road, so that In the construction environment, the span of the two towers is far more than 50 meters. In the original traction line laying operation, it is mainly to manually control the traction line reel or tail line to adjust the sag of the traction line. Due to the large construction span and the thinness of the traction line, the position of the traction line cannot be seen clearly during manual operation. Even if a telescope is used to observe, due to the instability of the high-altitude peak, the traction rope will still jump out of the observation range, resulting in excessive sag. Large, the traction rope is in contact with the highway, causing a construction accident
