A bracket for cable sealing

Abstract

The invention belongs to the technical field of electric power engineering, in particular to a bracket for cable plugging, includes a fixed pipe mounted at the end of the pipe, the fixed tube comprises two fixed semi-tubes symmetrical to each other, A flange is integrally formed on both sides of the fixed half pipe in the radial direction, A first through hole is formed on the flanged edge, A fixing bolt is pierced in the first through hole, the two fixing half pipes are fixedly connected by fixing bolts, A semi-circular end cap is integrally formed on the end face of the fixed half pipe, A half-ring position plate is integrally formed at the top end of the arc plate, A link plate is compose of an arc plate and a half-ring positioning plate, A link sleeve is composed of two connected plates, an outer wall of that connecting sleeve is provide with external threads, a nut is screwed on the connecting sleeve above the end cap through the external threads, and the nut is fixedly connectedby two and a half blocks, a semi-circular table-shaped rubber boss is connected at the free end of the arc-shaped plate, and the longitudinal section of the rubber boss is an isosceles trapezoid structure with a large upper and a small lower. The purpose of the invention is to solve the problems of low working efficiency and loose sealing caused by the structural defects of the existing cable plugging device.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to a bracket used for cable sealing. Background technique [0002] The cable pipe is a cable laying pipe. The material is generally cement, iron pipe or MPP pipe. The cable pipe opening generally needs to be blocked. If it is not blocked, once a pipe well leaks, it will easily lead to water accumulation along the pipe hole It spreads to other pipe wells, and then deteriorates the operating environment of the cable, causing the intermediate head to be soaked in water for a long time, greatly reducing the service life of the cable intermediate head. At present, the pipe holes in the underground opening and closing station are mostly sealed with cement, but cement is a rigid material, once it expands with heat and contracts with cold, it will cause cracks, and the cement is sealed inside the pipe with an irregular shape and poor pressure resistance , In ...
