Wire crossing device for power stringing

Abstract

The invention discloses a wire crossing device for power stringing, and the device comprises a pedestal fixedly disposed at the upper end of an insulating rod, and an upper cover which is hinged to the pedestal in a buckled manner. The interior of a pedestal groove of the pedestal is provided with a return pulley, and the interior of an upper cover groove of the upper cover is provided with an auxiliary wheel through an adjustment device. The outer wall of the pedestal is fixedly provided with a supporting rod, and the tail end of the supporting rod is hinged to a transmission rod. The upper end of the transmission rod is hinged to an upper connecting rod, and the upper end of the upper connecting rod and the outer wall of the upper cover are hinged together in a corresponding manner. The lower segment of the transmission rod is slidingly provided with an upper sliding sleeve in a sleeving manner, and the central part of the upper sliding sleeve is hinged to an insulating bar which extends downwards. The insulating rod is fixedly provided with a central sliding sleeve which is in sliding fit with the insulating bar in the axial direction. The upper part of the insulating rod is provided with a swinging cavity which cooperates with the lower segment of the transmission rod. The device can be quickly assembled and set up, can complete the wire crossing, selection and leading functions on the ground, is simple in operation, does not need climbing, and is high in safety.

Description

technical field [0001] The invention relates to a power line jumper. Background technique [0002] In the maintenance work of transmission lines, the work of replacing and removing the ground wire is often encountered. How to deal with and protect the power line of 10KV and above in the work is often a core issue. In the past construction, it is often used The following centralized processing methods: [0003] Line Loosening Method: Before the construction of the upper span (the line to be laid or replaced), loosen the lower span (the line that needs to be crossed under the laid or replaced line) to the ground, and restore the lower span after the construction of the upper span is completed line. This method is safe and reliable, but it needs to coordinate the owner or management unit of the cross-line, and the implementability is low. [0004] Spanning frame method: build a spanning frame at the lower span point, and the spanning frame is divided into a single-sided span...

AI Technical Summary

Problems solved by technology

In the urban-rural fringe area and rural areas, there are many types of down-spanning lines, such as mains power supply lines, telephone lines, radio and television broadcasting lines, broadband Internet access lines, etc. Therefore, if the above-mentioned loosening method is adopted, it will require the cooperation of multiple departments, which is very difficult , The construction period is long, and the feasibility is extremely small; if the above-mentioned spanning frame method or hanging ring method is adopted, there are still disadvantages that a spanning frame or hanging wire device needs to be erected, the operation is cumbersome, and the construction is time-consuming and expensive
