Problems solved by technology

[0002] Insulated hanging rods are mainly used in high-altitude test projects such as spring and autumn inspection pre-test, overhaul technical improvement and defect elimination sites. At present, the insulating hanging rods used in the maintenance site need to be spliced ​​one by one, time-consuming It is difficult to keep a safe distance from live equipment when splicing in small places such as some power outages, so it is necessary to improve the existing insulating hanging rods

Embodiment 1

[0018] Example 1, such as Figure 1 to Figure 3 As shown, the number of a group of hollow tubes 1 is two, the length of the two hollow tubes 1 is the same, the cross section of the hollow tube 1 is polygonal, preferably triangular, and the outer wall and the inner wall of the hollow tube 1 are all provided with Transition fillet, two hollow tubes 1 are set inside and outside, and the inner hollow tube 1 slides in the outer hollow tube 1. The material of the hollow tube 1 is glass fiber reinforced plastic epoxy resin, which is made of hand-rolled molding rod or mechanical pultrusion molding rod. The advantage of manual rolling is that it has high tension, but the longitudinal strength is smaller than that of machine-made pultrusion. The advantage of using electroscope mechanism pultrusion is that it has high strength, but the transverse tension is smaller than that of hand-rolled rods.

[0019] Such as figure 2 As shown, the inner hollow tube 1 is provided with a guide throug...

Embodiment 2

[0022] In embodiment 2, in order to prevent the limit post 2 from fully jumping out of the limit through hole 3 under the elastic force of the spring, thereby causing the limit cooperation between the limit post 2 and the limit through hole 3 and the guide through hole 4 to fail, Such as Figure 4 As shown, the limit column 2 is set in the shape of a tapered column with a small outer end and a large inner end, and the through hole formed by the limit through hole 3 and the guide through hole 4 is set as a cone that matches the shape of the tapered column Shape, after setting in this way, when the limit post 2 pops up, there is no fear that it will break away from the tapered hole formed by the limit through hole 3 and the guide through hole 4, which helps to improve the adjustment speed of the operation stretching and opening.

[0023] The telescopic insulating hanging rod provided by the present invention adopts the elongated and telescopic method of hollow tube inside and ou...

Abstract

The invention relates to a telescopic insulated hanging rod for electric power overhaul and belongs to the technical field of electric power. The telescopic insulated hanging rod comprises a set of hollow pipes which are mounted in a sleeving mode in sequence from inside to outside; every two adjacent hollow pipes are in sliding fit; clamping mechanisms are arranged between adjacent hollow pipes and comprise limiting columns located in the outer walls of the inner hollow pipes and limiting through holes located in the outer hollow pipes and in inserting fit with the limiting columns; guide through holes are formed in the outer walls of the inner hollow pipes; the limiting columns are located in the guide through holes, and springs are connected between the inner ends of the limiting columns and the inner walls of the hollow pipes; and the distances between the adjacent clamping mechanisms are larger than the distances between the limiting through holes and the ends of the sides, facingthe extending direction, of the hollow pipes. The telescopic insulated hanging rod does not need to be assembled and spliced, mounting operation and demounting operation are both easy, and storage, carrying and transporting are all convenient; and the safety distance between an operator and energized equipment can be guaranteed, and thus using safety is promoted significantly.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a telescopic insulating hanging rod for electric power maintenance. Background technique [0002] Insulated hanging rods are mainly used in high-altitude test projects such as spring and autumn inspection pre-test, overhaul technical improvement and defect elimination sites. At present, the insulating hanging rods used in the maintenance site need to be spliced ​​one by one, time-consuming It is difficult to keep a safe distance from live equipment when splicing in small places such as some power outages, so it is necessary to improve the existing insulating hanging rods. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides a telescopic insulating hanging rod for electric power maintenance. The hanging rod does not need to be assembled and spliced, and is easy to operate and easy to store. It can also ensur...
