Problems solved by technology

[0002] On the construction site under construction, there is no place for cables to be erected, and they are often laid on the ground. The cables are easily broken by passing vehicles. The mechanism of the breakage is analyzed. The cable core sheath is pressed on the cable core under the action of high voltage, so that the sheath The cable core produces a large friction, and then the sheath is axially deformed under pressure, which produces an axial pulling force on the cable core, causing the cable core to be pulled off
At the same time, part of the cable was broken because there were sharp objects such as stones in the lower part of the cable. When the car rolled over, the stone pierced the cable and caused the cable to break

Embodiment Construction

[0020] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The compression-resistant cable of the present invention includes a cable body 1. The cable body 1 includes an armor layer 11 and several core wires 2 placed in the armor layer 11. It is characterized in that: the bottom of the armor layer 11 is flat, and the armor layer The bottom of the inner cavity of the loading layer 11 is provided with a flexible base 3, and the flexible base 3 is provided with seat grooves 21 having the same number as the core wires 2. The core wires 2 are fixed in the seat grooves 21, and the core wires 2 include metal cable cores 23. And the sheath 22 wrapped outside the metal cable core 23, the liquid lubricant layer 24 is filled between the sheath 22 and the metal cable core 23, the liquid lubricant layer 24 makes the sheath 22 and the metal cable core 23 not contact, relatively A connecting colloid 25 is prov...

Abstract

The invention discloses a compressive cable. A liquid lubricating agent layer fills a space between a protection layer and a metal cable core, the liquid lubricating agent enables the protection layer and the metal cable core not to contact each other, a cable body is provided with a tension isolation pad, and the tension isolation pad is an elastic bag body internally filled with the liquid lubricating agent; connection colloid is arranged between the adjacent cables, and the connection colloid is bonded with the adjacent cables, so that the position of the cables is fixed; and an armor layer comprises a flat bottom and an arc top, and the arc top is divided into an inner layer, a middle layer and an outer layer. The compressive cable has the advantages of excellent compressive function.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to compression-resistant cables. Background technique [0002] On the construction site under construction, there is no place for cables to be erected, and they are often laid on the ground. The cables are easily broken by passing vehicles. The mechanism of the breakage is analyzed. The cable core sheath is pressed on the cable core under the action of high voltage, so that the sheath The cable core produces a large friction, and then the sheath is axially deformed under pressure, which produces an axial pulling force on the cable core, causing the cable core to be pulled off. At the same time, the reason why some cables are broken is that there are sharp objects such as stones in the lower part of the cables. When the car runs over, the stones penetrate the cables and cause the cables to break. Contents of the invention [0003] The technical problem to be solved by the present i...
