Embodiment Construction

[0024] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] The special cable of the present invention includes a cable body 1, the cable body 1 includes an armor layer 11 and several cables 2 placed in the armor layer 1, wherein: the bottom of the inner cavity of the armor layer 11 is provided with a flexible base 3, The flexible base 3 is provided with a number of seat grooves 21 equivalent to the number of cables 2, and the cables 2 are fixed in the seat grooves 21. The cable 2 includes a metal cable core 23 and a sheath 22 wrapped outside the metal cable core 23. A liquid lubricant layer 24 is filled between the sheath 22 and the metal cable core 23, the liquid lubricant layer 24 keeps the sheath 22 from contacting the metal cable core 23, and a connecting colloid 25 is arranged between adjacent cables 2 to connect Glue 25 bonds the adjacent cables 2 to fix the position between the cables 2. ...

Abstract

The invention discloses a special cable. The space between a sheath layer and a metal cable core is filled with a liquid-state lubricant layer, so that the liquid-state lubricant layer enables the sheath layer not to be in contact with the metal cable core; a connecting colloid is arranged between adjacent cables and bonds the adjacent cables to enable the position between the cables to be fixed; an armor layer comprises a flat bottom and an arc top; the arc top comprises an inner layer, a middle layer and an outer layer; the special cable further comprises a cable connector apparatus; the cable connector apparatus consists of butting parts on two sides and a connecting part in the middle; the connecting part comprises cable core insertion holes with the same number as cables; contact blocks are arranged in the cable core insertion holes and are connected with guide cores through springs; each butting part comprises a first compaction part and a second compaction part; and the first compaction part comprises a cable insertion hole communicated with the corresponding cable core insertion hole, a first compaction housing and a flexible filling layer filling the space between the first compaction housing and the corresponding cable insertion hole. The special cable has the advantage of excellent compression resistance function.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to special cables. Background technique [0002] In the construction site, the cable is easy to be broken by passing vehicles. The analysis of the breaking mechanism is that the cable core sheath is pressed on the cable core under the action of high pressure, which causes a large friction between the sheath and the cable core, and then the sheath The sleeve deforms axially under the action of 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 invention is to provide a special cable with excellent compression resistance fun...
