Description

A kind of bucket block and method for hooking and picking up the bucket block on an overhead line

technical field

The invention relates to the field of engineering machinery and the technical field of foreign matter removal for power transmission lines, in particular to a bucket block and a method for hanging and picking up the bucket block from an overhead line.

Background technique

The overhead transmission line is one of the important components of the power system, which undertakes the important function of power transmission, and is mainly composed of conductors, overhead ground wires, insulator strings, towers, grounding devices and other parts. Any problem in any of its components will directly affect the safe and stable operation of the transmission line. However, transmission lines are erected in the wild, and have been affected by natural conditions and the surrounding environment for many years. Therefore, accidents such as lightning damage, bird damage, pollution flashover, ice flashover, and external damage often occur.

In recent years, with the rapid growth of buildings, the number of construction points near overhead lines has increased, and it is not uncommon for wires to break and loose strands due to external damage. In order to ensure the safe and stable operation of lines, damaged wires should be repaired in time. In the wire repair work, the ground operator needs to slide the tumbler along the wire to the wire damage, and then hoist the insulating ladder on the wire and hang it, so that the wire repairer can enter the line along the insulating ladder to carry out repair work. Due to the different environments of overhead lines, not all line passages can be walked under (such as rivers, lakes, woods, small buildings, etc.). At this time, another operation method needs to be adopted, that is, a soft ladder head is hung near the tower body, and a control rope is left on the cross arm. After the operator enters the ladder head, it slides to the repairing place for repair. No matter which method, the staff can not reach the operation point quickly, the former is affected by environmental factors, and the latter consumes a lot of physical strength of the staff, both of which have disadvantages. Then how to make the somersault block reach the damaged place in the first time has become a problem that needs to be solved.

In the transmission line of 220kV and below, the connection method of single wire or double split wire is usually used. Due to the limited specifications of the wires, operators cannot reach the damaged part by routing, which requires the use of ladder heads for repair work. If the razor is hung on the wire, it needs to cooperate with the insulating rope through the bucket block. Usually the wire is hung with a bucket block by an operator on the cross arm of a base tower adjacent to the damaged part, and the required bucket block and insulation operating rod are transferred to the tower with an insulating block and an insulating rope, and finally the tower The upper operator uses the insulated operating rod to pick and hang the trolley with the insulated rope on the wire to be repaired. The difficulty of the whole process lies in the hanging of the insulating operating rod. In order to ensure safety, the length of the insulating operating rod is often greater than the minimum safety distance. The job site is outdoors, which is easily affected by the wind, which makes the whole hanging process more difficult. There are three major disadvantages in the conventional tumbler tackle: 1. The conventional tumbler tackle is heavy and inconvenient to pick up. 2. No sealing, easy to come out from the wire. 3. The loading and unloading operation is cumbersome, time-consuming and labor-intensive.

Contents of the invention

In view of the above-mentioned deficiencies in the prior art, the present invention aims to provide a method for unmanned aerial vehicles to hang and pick up the bucket tackle on the overhead line. The bucket tackle in this method is lighter in weight and has better flexibility during operation After being pulled, it is not easy to come out from the wire, ensuring that the ladder head can pull up the wire smoothly. At the same time, using this method to hang the tumbler tackle saves time and effort and is not affected by the environment of the line passage.

Working principle of the present invention:

The process of hanging the tumbler block is as follows: First, after fixing an elastic rope through the hanging ring 4, hang it on the UAV to connect the UAV and the tumbler block; At this time, due to the upward traction effect of the drone, the closing lock piece 3 slides up along the two side walls of the vertical direction of the hook 1, and due to the engagement of the horizontal limit post 15 and the bar-shaped through hole 32, the closing lock The piece 3 will not be separated from the hook 1, and can make the opening 13 of the hook 1 always open during the operation; secondly, according to the real-time transmission of the UAV shooting system, find the place that needs to be repaired on the wire, and operate the UAV Adjust the height and direction so that the wire can enter the groove 14 through the opening 13 of the hook 1. At this time, after the rope is released and the traction of the drone is lost, the closing lock piece 3 is vertically along the hook 1 due to its own gravity. The two side walls in the direction move down, and the arc-shaped locking end 33 can be fitted with the arc-shaped side of the lower hook body 11 (the end 31 of the closing lock piece 3 close to the opening 13 moves downward and is inserted into the card slot 121 inside), the opening 13 is closed; finally, the tumbler block is hung on the wire of the overhead line, and the operator fixes one side of the ladder to a fixed object, and climbs the other side of the ladder to climb the ladder to repair the wire at a high place Operation.

The process of taking the tumble block is as follows: the staff operating on the soft ladder puts the rope passing through the hanging ring 4 on the drone, reconnects the drone and the tumble block, and then the staff gets off the soft ladder and operates the drone to pull up and close The locking piece 3, due to the traction force of the drone, the closed locking piece 3 slides up along the two side walls in the vertical direction of the hook 1, and the arc-shaped locking end 33 is connected to the arc-shaped side of the lower hook body 11 Separation (one end 31 of the closed locking piece 3 close to the opening 13 moves upwards and escapes from the draw-in groove 121), the opening 13 is opened, and the lead wire escapes from the opening 13 of the hook 1, so that the tumble block is separated from the lead wire, and the tumble block is removed.

The above-mentioned embodiment is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited by the above-mentioned embodiment, and any other changes, modifications, substitutions, combinations, Simplifications should be equivalent replacement methods, and all are included in the protection scope of the present invention.
