Description
Technical Field
The invention relates to the field of engineering machinery and the technical field of foreign matter removal of power transmission lines, in particular to a trailed skip car capable of being bridged and a method for hanging and taking the trailed skip car on an overhead line.
Background
The overhead transmission line is one of important components of an electric power system, bears important functions of electric power transmission, and mainly comprises a lead, an overhead ground wire, an insulator string, a tower, a grounding device and the like. Any component of the power transmission line has a problem, and the safe and stable operation of the power transmission line can be directly influenced. However, the transmission line is erected in the field and is influenced by natural conditions and surrounding environment for a long time, so accidents such as lightning damage, bird damage, pollution flashover, ice flashover, external force damage and the like often occur.
In recent years, with the rapid growth of buildings, construction points near overhead lines are increased, the phenomena of strand breakage and strand scattering of the wires caused by external force damage are frequent, and damaged wires are required to be repaired in time in order to ensure the safe and stable operation of the lines. In the wire repair work, ground operating personnel need to slide a trolley capable of bridging to a damaged part of the wire along the wire, then hang an insulating flexible ladder on the wire and hang the insulating flexible ladder, and a wire repairer can enter a circuit along the insulating flexible ladder to perform repair work. Because the environments of overhead lines are different, all the line channels can not run below (such as rivers, lakes, forests, small buildings and the like). At the moment, another operation method is needed, namely, a rope ladder head is hung near the tower body, a control rope is reserved on the cross arm, and after an operator enters the ladder head, the operator slides to a repairing position to repair. In either method, the worker cannot arrive at the operation point quickly, the former is influenced by environmental factors, and the latter consumes a large amount of physical strength of the worker, which has disadvantages. How to make the heel block arrive at the injury part at the first time becomes a problem to be solved.
In the power transmission line of 220kV and below, a connection mode of a single wire or a double split wire is generally adopted. Due to the limitation of the specification of the wire, the operator cannot reach the damaged part in a wiring mode, and therefore the repairing work needs to be carried out by means of the ladder head. If the shaving head is hung on the conducting wire, the shaving head needs to be matched with the insulating rope through a sidecar which can be bridged. Usually, a cross arm of a base tower adjacent to a damaged part is ascended by a worker, the needed skip car capable of bridging and an insulating operating rod are transmitted to a tower through the insulating skip car and the insulating rope, and finally, the skip car capable of bridging and provided with the insulating rope is hung on a conductor needing to be repaired by the worker on the tower through the insulating operating rod. The difficulty of the whole process is in the hanging of the insulating operating rod, in order to guarantee safety, the length of the insulating operating rod is often greater than the minimum safe distance, after the tradable bucket pulley is hung, great inconvenience can be brought to operation, and in addition, the operation site is outdoor and is easily influenced by wind, so that the whole hanging process is difficult. The conventional bridging-capable following bucket pulley is hung and taken to have three disadvantages: 1. the conventional bucket-following pulley which can be bridged is heavy and inconvenient to hang and take. 2. And the cable is easy to be separated from the lead without a seal. 3. The hanging operation is complicated, and time and labor are wasted.
