Problems solved by technology

The use of the cable through-pipe protector in this invention can avoid direct contact between the cable and the end surface of the protective pipe, avoid scratches on the cable, and protect the cable. However, the cable through-pipe protector has a fixed size. Different, there are many standards for the size of the cable conduit. If the cable conduit protector of the present invention is used, it is necessary to produce, purchase and carry different cable conduit protectors for different sizes of cable conduit, which increases the production cost and It is difficult to transport, and if the size used is not suitable, it is easy to damage the cable conduit

Embodiment

[0040] Such as Figure 1 to Figure 4 As shown, an expandable cable conduit protector includes a conduit protector body 001. The conduit protector body 001 includes a first half-pipe body 1 and a second half-pipe body 2 that are oppositely arranged and relatively movable. Half pipe 1 and second half pipe 2 are provided with semicircular bearings 3 in front of them, and a number of first rollers 4 are worn on the bearings, and a capacity expansion is provided between the first half pipe 1 and the second half pipe 2. structure, the pipe-piercing protector also includes a limit lock for locking the pipe-piercing protector at a certain position.

[0041] The conduit protector in this scheme is a circumferential and radial expandable structure, which can be used on different types of cable conduits, and can be expanded and adjusted according to the size of the cable conduits. It has strong versatility, wide application range, and saves energy. Economical cost, there is no need to p...

Abstract

The invention discloses a capacity-expandable cable pipe-penetrating protector, and belongs to the technical field of cable protectors. The capacity-expandable cable pipe-penetrating protector comprises a pipe penetrating protector body, the pipe penetrating protector body comprises a first half pipe body and a second half pipe body, which are oppositely arranged and can move relatively. Semicircular bearings are arranged in front of the first half pipe body and the second half pipe body; a plurality of first rollers penetrate through the bearings, a capacity-expandable structure is arrangedbetween the first half pipe body and the second half pipe body, the pipe-penetrating protector further comprises a limiting locking piece for locking the pipe-penetrating protector at a certain position, and the pipe-penetrating protector in the scheme is high in universality, wide in application range and high in installation efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of cable protection devices, in particular to an expandable cable pipe protector. 【Background technique】 [0002] With the rapid development of science and technology, the underground laying form of high-voltage cable conduits gradually replaces the traditional form of overhead cables. High-voltage cable conduits include plastic conduits and stainless steel conduits. When using plastic conduits, plastic conduits are low in cost and light in weight , the connection is simple, but the strength is not enough. When there are many threads, the opening of the pipe is easy to crack and damage. The stainless steel pipe has high mechanical strength, no deformation, high pressure resistance, and vibration resistance. , In the process of laying high-voltage cables, especially when there is a bending angle, it is easy to scratch and scratch the cable insulation layer, which directly affects the electrical insulation p...
