Description

A bucket block for spanning horizontally arranged double-split conductor spacers

Technical field:

The invention relates to a tumbler block for spanning horizontally arranged double-split conductor spacers, which is widely used in work such as live repair of horizontally arranged double-split conductors on power transmission lines, replacement of spacer rods, removal of foreign objects in conductors, etc., and belongs to the technical field of on-site live maintenance .

Background technique:

At present, transmission lines are prone to defects such as entanglement of foreign objects, loose and damaged spacers, and broken wires. In order to avoid the expansion of defect hazards and cause line tripping accidents, endangering line safety, on the premise of ensuring continuous power supply to the area, live work is generally used to deal with the above faults. . Among them, the live working method for single-strand conductors is usually as follows: the ground potential electrician on the tower first hangs the bucket block on the working phase conductor, slides to the working position under the traction of the insulating rope, and transfers the manned tackle of the transmission line to the conductor position through the insulating rope And after the installation is firm, the personnel can climb the insulating ladder to the working position for equipotential elimination. If the power transmission line adopts horizontally arranged double-split conductors, since the tumbler block can only move on a single conductor, for defects far away from the pole tower, they cannot reach the working position due to the blocking of the spacer rods, resulting in failure to eliminate the defects in time. Therefore, there is an urgent need to develop a device that can reach a designated position by crossing the spacer bar, so as to shorten the defect processing time, improve the range and efficiency of power transmission live work, and ensure the safety of live work.

Invention content:

The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a simple structure, safe and reliable, flexible adjustment, stable installation, wide application range, improve the efficiency of live work, and ensure the safety of live work for straddling horizontally arranged double split conductors Spacer bar tackle.

The purpose of this book can be achieved through the following measures: a bucket block for spanning the horizontally arranged double-split wire spacer, which is characterized in that it includes a nail, and the two sides of the nail are respectively provided with bearings and upper support plates in sequence. The two ends of the nail are fastened and blocked by fixing bolts. There is a semicircular hanging ring in the center of the nail, and an insulating rope ruler is tied to the semicircular hanging ring. The insulating rope ruler passes through the upper end of one of the upper supporting plates. The outer part of each bearing The distance between the inner sides of the two routing pulleys is L1 is 320mm, the distance between the outer sides of the two routing pulleys is 480mm, and the lower end of each upper support plate is connected to the lower part through a connecting screw. The support plate, the lower support plate can rotate 360°, and the lower support plate is connected with a transmission pulley.

In order to further realize the object of the present invention, described two wire-running pulleys are made by the aluminum alloy pulley that is 150mm in wheel rim diameter, 60mm in diameter of slender waist axle.

In order to further realize the purpose of the present invention, the length of the insulating rope ruler is 7.5 meters.

Compared with the prior art, the present invention can produce the following positive effects: the present invention completes the tumbler block across the horizontally arranged double-split conductor spacers, and can effectively cross the horizontally arranged double-split conductor spacers to reach the position that needs to be operated. It solves the problem that the original tumbler block cannot cross the spacer bar for equipotential operation, ensures the reliable and stable operation of the equipment, improves the safety factor and operating efficiency, and ensures the safety of live working. which has:

1. Simple structure and easy installation. The electrician on the tower climbs the tower to a suitable position, and the electrician on the ground passes the bucket block and the operating rod of the present invention to the electrician on the tower, and the electrician on the tower uses the insulating operating rod to pick and hang the bucket block with the insulating rope on the working phase wire, and the electrician on the ground Use the insulating rope to pull the heel block to slide over the spacer to the working position, which solves the problem that the single wire heel block cannot pass through the spacer and cannot reach the working position and cannot carry out live maintenance operations, ensuring reliable and stable operation of the equipment and improving the reliability of power supply .

2. The equipment is reliable in performance, mature in technology, perfect in function and reasonable in structure. The inner distance of the cable pulleys on both sides is 320mm, and the outer distance is 480mm, which meets the width requirements of double-split conductors of 320mm-420mm, and ensures that the two cable pulleys are in double-split Glides smoothly on the wire.

3. The semi-circular hanging ring has an insulating rope ruler with a length of 7.5 meters (mainly used for measuring the distance between the middle phase and the lower phase wire of the double-circuit tower), which can be used to measure the distance between the wire before and after the load and the object being crossed, and judge according to the distance change Whether live work can be carried out.
