Description

Technical Field

[0001] The utility model relates to the technical field of sensor cables, in particular to a sensor cable for high temperature resistant drag chains. Background Art

[0002] A drag chain, also known as a cable carrier, is a device that binds cables or wires or pneumatic and hydraulic pipes to facilitate their rotation and movement. A sensor cable is a cable used to connect sensors to control systems. It is mainly used to transmit signal data collected by sensors, thereby realizing the monitoring and control of various physical quantities. During use, the drag chain usually transmits signals through sensor cables.

[0003] The sensor cable can enable the drag chain to drive the equipment (for example: drilling machine) to move accurately to the specified position. However, in high-temperature operation industries such as metallurgy and special high-temperature production environments, ordinary sensor cables are limited by cable structure and materials and are not suitable for high temperature, heavy oil pollution, frequent movement and other occasions. Their safety and practicality cannot be guaranteed, which affects the life of the cable and increases the potential for accidents. Traditional high-temperature cables use Teflon, silicone and other materials for insulation and sheath. These materials meet the requirements of high-temperature operations, but Teflon material is too hard and not easy to bend. Silicone rubber has poor strength and tear resistance and cannot meet the use requirements of drag chains. In order to further improve the service life and safety of the cable, we propose a high-temperature resistant sensor cable for drag chains. Utility Model Content

[0004] The purpose of the utility model is to provide a sensor cable for a high temperature resistant drag chain in order to further improve the service life and safety of the cable.

[0005] To achieve the above object, the utility model provides the following technical solutions: a sensor cable for a high temperature resistant drag chain, comprising an anti-wear layer, a protective layer is arranged inside the anti-wear layer, an elastic layer is arranged inside the protective layer, a second heat conductive layer is arranged inside the elastic layer, and a cable is arranged inside the second heat conductive layer;

[0006] The cabling comprises:

[0007] Three first insulation layers are circumferentially equidistantly arranged inside the second heat-conducting layer, an anti-interference layer is arranged inside the three first insulation layers, a second insulation layer is arranged inside the anti-interference layer, two first heat-conducting layers are symmetrically arranged inside the second insulation layer, an insulating layer is arranged inside the two first heat-conducting layers, and an alloy conductor is arranged inside the insulating layer.

[0008] As a further solution of the utility model: the anti-wear layer is woven from a plurality of galvanized steel wires, and the galvanized steel wires are made from high-quality carbon structural steel that is drawn and then galvanized.

[0009] As a further solution of the utility model: the protective layer is made of a glass fiber blank tape coated with thick silicone rubber, and the glass fiber blank tape is made of high-temperature resistant and high-strength glass fiber knitted or woven.

[0010] As a further solution of the utility model: the elastic layer is made of silicone rubber, and the second heat-conducting layer and the first heat-conducting layer are both made of heat-conducting insulating elastic rubber.

[0011] As a further solution of the utility model: the first barrier layer and the second barrier layer are both high molecular polymers obtained by polymerizing tetrafluoroethylene as a monomer, and the insulating layer is made of fluorine-containing monomers through homopolymerization or copolymerization.

[0012] As a further solution of the utility model: the alloy conductor is made of copper and nickel fused together, two filling layers are symmetrically arranged inside the second isolation layer, and the filling layers are made of woven aramid fibers.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By setting up the cable, through the anti-wear layer, elastic layer, filling layer and insulating layer, the cable can be effectively protected from damage caused by the drag chain, breakage and leakage, and the cable can be made soft and easy to bend. At this time, the alloy conductor can effectively increase the service life of the cable. At the same time, the anti-interference layer can prevent the signal transmitted through the alloy conductor from being interfered by external signals. At this time, the first isolation layer and the second isolation layer can separate and protect the anti-interference layer from the first thermal conductive layer and the filling layer. At the same time, the first thermal conductive layer and the second thermal conductive layer can effectively avoid the situation where the temperature is too high and the loss is too fast. According to the above-mentioned protective layer, elastic layer, first isolation layer, second isolation layer, insulating layer, alloy conductor and filling layer, they are all resistant to high temperature and can be used in high temperature environment, so that reliable electrical performance, stable data transmission characteristics, balanced structure and symmetrical and uniform force can be achieved, thereby further improving the service life and safety of the cable, and effectively meeting the use requirements of the drag chain cable in high temperature environment.

[0024] In this embodiment: during use in a high-temperature environment, when the drag chain drives the anti-wear layer 1 to bend frequently, the anti-wear layer 1 is woven by a plurality of galvanized steel wires, so the mechanical strength of the cable 2 can be enhanced by the anti-wear layer 1, so that the cable 2 is protected from damage by other machines such as the drag chain equipment. At the same time, the elastic layer 4 is made of silicone rubber, which has the characteristics of high temperature resistance and high elasticity, and can make the cable 2 soft and easy to bend. At this time, the filling layer 207 is woven by aramid fiber, which has the characteristics of high temperature resistance, corrosion resistance, high strength, high toughness and light weight. Therefore, when the cable 2 is frequently bent under the drive of the drag chain, the cable 2 is prevented from breaking;

At this time, the insulating layer 205 has the characteristics of high temperature resistance, corrosion resistance, and insulation, which can prevent the cable 2 from leaking. At the same time, the anti-interference layer 202 has the ability to resist external signal interference, which can prevent the signal transmitted through the alloy conductor 206 from being interfered by external signals. At this time, the first isolation layer 201 and the second isolation layer 203 are both resistant to high temperature and tightened, so they can resist interference. The first heat-conducting layer 204 and the second heat-conducting layer 207 are separated and protected. At the same time, since the first heat-conducting layer 204 and the second heat-conducting layer 5 are made of heat-conducting insulating elastic rubber, they have the characteristics of high thermal conductivity, high pressure resistance, high elasticity and insulation, so that they can respectively conduct the temperature on the anti-wear layer 1, the protective layer 3, the elastic layer 4 and the temperature generated by the alloy conductor 206 transmitting the signal, avoiding uneven temperatures on the anti-wear layer 1, the protective layer 3, the elastic layer 4 and the alloy conductor 206, resulting in excessive loss at the part with too high temperature;
