Embodiment 2

[0055] In a typical embodiment of the present invention, such as image 3 As shown, this embodiment discloses a high-voltage cable laying device with a special-shaped lumen. The difference from Embodiment 1 lies in that the shape of the bending section 12 of the pipeline 1 is different from Embodiment 1 in this embodiment.

[0056] It should be noted that, in this embodiment, the plane passing through the central axis of the vertical section 11 and perpendicular to the horizontal section 13 is defined as the reference plane, the side of the reference plane away from the horizontal section 13 is the outer side, and the side close to the horizontal section 13 is inside.

[0057] Such as image 3 As shown, in this embodiment, the bending section 12 is divided into a connected first bending portion 121, a first bending portion 122 and a third bending portion 123, wherein one end of the first bending portion 121 is connected to The vertical section 11, the other end is connected ...

Embodiment 3

[0062] In a typical implementation of the present invention, this embodiment discloses a high-voltage cable laying device with a special-shaped lumen. The difference from Embodiment 1 is that the rollers are replaced by protrusions provided on the ring member 23 .

Abstract

The invention discloses a special-shaped pipe cavity high-voltage cable laying device and method, and belongs to the technical field of cable construction. A specially-arranged clamping mechanism and a pipeline matched with the clamping mechanism are adopted, and the clamping mechanism can drive a power cable to be bent in the pipeline when running along the pipeline, so that the problem that an existing power cable is inconvenient to bend can be solved, and the laying time and cost are reduced. The device comprises a pipeline and a clamping mechanism, wherein the clamping mechanism is arranged in the pipeline, and the clamping mechanism can make contact with the inner wall of the pipeline; a handle is arranged at the end of the pipeline and penetrates through the pipe wall of the pipeline, the part, which is located in the pipe wall, of the handle is connected with a traction cable, and the traction cable is connected with the clamping mechanism; and the pipeline is provided with a bent section, the inner side pipe wall of the bent section is in an arc shape, and the traction cable can be attached to the inner side pipe wall of the bent section to slide.

Description

technical field [0001] The invention belongs to the technical field of cable construction, and in particular relates to a device and method for laying high-voltage cables with special-shaped lumens. Background technique [0002] Power cables refer to cables with large wire diameters, generally 3-core or 4-core, with thicker phase-to-phase insulation and protected by metal armor on the outside. They are mainly used in power supply systems as the backbone of three-phase industrial power or single-phase civilian power. [0003] Cable faults caused by mechanical damage account for a relatively large proportion of cable faults. During the construction of power cables, mechanical damage is easily caused. The cable is damaged due to excessive mechanical tension and the cable is damaged due to excessive bending of the cable. Some mechanical damage is very slight. Cause failure, and the damaged part develops into failure after several months or even 1-2 years of use. The shape of th...
