Power stringing line-cross device

Abstract

The invention discloses a power stringing line-cross device which comprises a pedestal fixed on the upper end of an insulating rod and an upper cover hinged and buckled to the pedestal. A base wheel is installed in a pedestal groove of the pedestal, and an auxiliary wheel is installed in an upper cover groove of the upper cover through an adjusting device. A support bar is fixed to the outer wall of the pedestal, a transfer rod is hinged to the tail end of the support bar, and an upper connecting rod is hinged to the upper end of the transfer rod. The upper end of the upper connecting rod and the outer wall of the upper cover are correspondingly hinged together, and an upper sliding sleeve slidingly sleeves the lower section of the transfer rod. An insulating bar downwardly extending along the insulating rod is hinged to the central section of the upper sliding sleeve, and an intermediate sliding sleeve in sliding fit with the insulating bar in the axial direction is fixed on the insulating rod. The upper portion of the insulating rod is provided with a swinging chamber matching with the lower section of the transfer rod. The power stringing line-cross device can be rapidly assembled and erected, enables line crossing, jumping and leading on the ground, and is easy to operate and high in safety. No climbing is required.

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
