Description

Towline cable for industrial equipment

Technical Field

The utility model relates to the technical field of cables, in particular to industrial equipment is with tow chain cable.

Background

With the development of science and technology, special equipment such as robots increasingly play an important role in modern science and technology and economic activities, the transmission power and signals of the special equipment such as robots must be completed by cables, and the special equipment such as robots can drive the cables to move back and forth during the activities. The tow chain is commonly called as a tank chain, and in order to prevent the cable from being entangled, abraded, pulled off, hooked and scattered in the occasion where the cable needs to move back and forth, the cable is often placed into a protective tow chain to form a tow chain cable, so that the cable is protected, the cable, an oil pipe, an air pipe and the like can also move back and forth along with the tow chain, the equidistant moving stroke during the back and forth movement is realized, half of the cable length can be saved, and the cost is reduced. However, when the cable moves back and forth along with the tow chain, the movable position of the tow chain is fixed, and thus the cable is bent and extended repeatedly at the movable position corresponding to the tow chain, and the cable is easily damaged at the movable position.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is how to make the difficult damage of cable that corresponds tow chain active position in the tow chain cable.

In order to solve the technical problem, the utility model provides a tow chain cable for industrial equipment, including the sinle silk that is used for transmitting electricity, the surface cladding of sinle silk has fire-resistant insulation layer, fire-resistant insulation layer's surface cladding has insulating inner sheath, the surface cladding of insulating inner sheath has the shielding layer, the surface cladding of shielding layer has insulating oversheath.

Preferably, the shield layer is a tin-plated copper shield layer that is grounded.

Preferably, the insulating inner sheath and the insulating outer sheath are both polyethylene sheaths or crosslinked polyethylene sheaths.

Preferably, the fire-resistant insulating layer is a wrapped mica tape.

Preferably, the wire core is a copper conductor wire core.

The utility model discloses following beneficial effect has: the towline cable for industrial equipment has insulating inner sheath and insulating oversheath, and this makes intensity and the toughness of cable increase substantially, even the cable is bent repeatedly in the active position department that corresponds the towline like this and is extended, and the cable is difficult damaged yet.

Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As shown in figure 1, the towline cable for industrial equipment comprises a copper conductor wire core 1 for power transmission, wherein the outer surface of the copper conductor wire core 1 is coated with a mica tape 2, the outer surface of the mica tape 2 is coated with an insulating inner sheath 3, the outer surface of the insulating inner sheath 3 is coated with a shielding layer 4, and the outer surface of the shielding layer 4 is coated with an insulating outer sheath 5.

The copper conductor wire core 1 has low resistivity and good conductivity. The mica tape 2 is a fire-resistant insulating material, has excellent high temperature resistance and combustion resistance, and is wrapped on the outer surface of the copper conductor wire core 1 in a wrapping mode, so that the mica tape 2 is required to be flat in wrapping and has no curling or leakage. The insulating inner sheath 3 is generally made of polyethylene or cross-linked polyethylene, and has good insulating properties. The shielding layer 4 is a tinned copper shielding layer which is grounded, an external interference signal can be led into the ground by the shielding layer 4, the interference signal is prevented from entering the inner-layer copper conductor wire core 1 to interfere, and therefore the loss of a transmission signal is reduced. The insulating outer sheath 5 is the same as the insulating inner sheath 3, is usually made of polyethylene or cross-linked polyethylene, and has good insulating property.

The towline cable for industrial equipment of this embodiment has insulating inner sheath 3 and insulating oversheath 5, and this makes the intensity and the toughness of towline cable for industrial equipment increase substantially, even like this the cable is bent repeatedly in the active position department that corresponds the towline and is extended, and the cable is difficult damaged yet.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the protection scope of the present application, and although the present application is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present application without departing from the spirit and scope of the technical solutions of the present application.
