[0002] A cable is a device for transmitting electrical energy or signals. It is usually composed of several or several groups of wires, which may be insulated from each other and twisted around a central wire. The entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power and external insulation. It is an indispensable infrastructure in modern society and is widely used in various fields such as electricity, communications, data, transportation, industry, construction, home and entertainment. Among them, power cables are mainly used to transmit and distribute electricity, and undertake the important task of power transmission and distribution in the power system. Communication cables are mainly used to transmit various signals, such as telephone, data, video, etc.

[0003] The patent with application number 202122590717.4 discloses a tensile cable for thin coal seam mining machines. The application uses pre-tensioned cables to maintain compressive stress in the rest of the tensile cable, so that when the tensile cable is subjected to tension, it can have greater resistance and high reliability. Combined with the above application and compared with the existing cable structure, the commonly used tensile method is to use steel belt armor to achieve tensile resistance. However, the tensile method and function of a single armor are single, and it cannot provide better protection for the cable, thereby affecting the practicality and safety of the existing tensile cables. For this reason, we propose a tensile cable for thin coal seam mining machines. Utility Model Content

However, the tensile-resistant method and function of a single armor are single, and at the same time, it cannot provide better protection for the cable, thereby affecting the practicality and safety of the existing tensile-resistant cable.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tensile-resistant cable for a thin coal seam coal mining machine, comprising an outer sheath protective layer, a tensile-resistant protective layer is arranged on the inner side of the outer sheath protective layer, an inner sheath protective layer is arranged on the inner side of the tensile-resistant protective layer, the inner side of the inner sheath protective layer is filled with a protective filler, a cable core body is arranged in the protective filler, a core protective sheath layer is arranged on the outer side of the cable core body, the tensile-resistant protective layer comprises an insulating shielding outer sheath layer and an insulating shielding inner sheath layer, the insulating shielding outer sheath layer is arranged on the outer side of the insulating shielding inner sheath layer, a tensile-resistant and anti-deformation strip is arranged and connected between the insulating shielding outer sheath layer and the insulating shielding inner sheath layer, a tensile-resistant copper wire is arranged on the inner side of the tensile-resistant and anti-deformation strip, and a metal wire braided mesh belt layer is also arranged between the outer side of the insulating shielding outer sheath layer and the outer sheath protective layer.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) By setting up the combined tensile strength method, a tensile strength protective layer is set on the inner side of the cable. The tensile strength protective layer can play a shielding effect by setting up a double-layer insulation shielding layer. At the same time, a bow-shaped tensile strength and deformation resistance strip is set inside it.

At the same time, it complements the outer tensile protective layer to play a role in strengthening the tensile function, thereby improving the stability and functionality of the cable.

[0019] Example 1

[0020] See also Figure 1 、 Figure 2 and Figure 3 The utility model provides a technical solution: a tensile cable is a cable with special mechanical strength and durability, which is widely used in situations where the cable needs to move back and forth and withstand certain mechanical stress. As a power and control cable, the tensile cable is mainly used in cable tracks, transportation lines, handling cranes, elevators and other environments where the cable needs to move frequently and withstand tension. It can be used in dry or humid indoor or outdoor environments and has a high ability to resist mechanical stress, especially in applications with both tensile and torsional stress. A tensile cable for thin coal seam shearing machine includes an outer sheath protective layer 100, an outer sheath protective layer 110, and an outer sheath protective layer 110. The inner side of the layer 100 is provided with a tensile protective layer 200, the inner side of the tensile protective layer 200 is provided with an inner sheath protective layer 101, the inner side of the inner sheath protective layer 101 is filled with a protective filler 102, the protective filler 102 is provided with a cable core body 104, the outer side of the cable core body 104 is provided with a core protective sheath layer 103, the tensile protective layer 200 includes an insulating shielding outer sheath layer 201 and an insulating shielding inner sheath layer 202, the insulating shielding outer sheath layer 201 is provided on the outer side of the insulating shielding inner sheath layer 202, and the insulating shielding outer sheath layer 201 and the insulating shielding inner sheath layer 202 are connected.

A metal wire braided mesh belt layer 207 is also provided between the outer side of the insulating shielding outer sheath layer 201 and the outer sheath protective layer 100. When the cable in the application is used, during the laying or installation process, if the cable is squeezed, the cable will be squeezed and deformed when subjected to external force. When the tensile protective layer 200 is squeezed and deformed, the tensile and anti-deformation strip 203 provided between the insulating shielding outer sheath layer 201 and the insulating shielding inner sheath layer 202 is deformed synchronously under the force and produces a certain rebound. The force acts to resist pressure, and at the same time, when the cable is touched by a sharp object, the metal wire mesh tape layer 207 arranged on the outside of the insulating shielding outer sheath layer 201 can also play a protective role. Through the action of the metal wire mesh tape layer 207, the insulating shielding outer sheath layer 201 and the insulating shielding inner sheath layer 202, a multi-layer protection effect is played, which improves the safety during use. At the same time, the tensile copper wire 204 on the inside of the tensile and deformation-resistant strip 203 provides a certain tensile strength, and the inner reinforced tensile core 206 arranged at the center can better resist tension, thereby improving the practicality of the cable.
