Problems solved by technology

According to the current requirements, the control wire core only needs a small cross-section, but during the use of the cable, the cable moves frequently with the movement of the shearer, and the control wire core cross-section is small, so there is a problem in the frequent movement and bending. May be pulled off, so that it cannot play the role of control and monitoring

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, a tensile type coal shearer cable according to the present invention includes a power core conductor 1, and a power core insulation layer 2 is arranged outside the power core conductor 1, and a power core insulation layer 2 is arranged outside the power core conductor 1. The insulating layer 2 is provided with a semi-conductive shielding layer 3. The power core conductor 1, the power core insulating layer 2 and the semi-conductive shielding layer 3 form a power core unit, and there is at least one power core unit. A control wire core tensile unit is arranged next to the power wire core unit, and the control wire core tensile unit includes at least one control wire core load-bearing core 4, and the control wire core load-bearing core 4 is twisted with high-strength aviation steel wire rope , the single wire diameter of ...

Abstract

The invention relates to a tensile cable for a coal cutter. A power core conductor is included, a power core insulation layer is arranged outside the power core conductor, a semi-conductive shielding layer is arranged outside the power core insulation layer, the power core conductor, the power core insulation layer and the semi-conductive shielding layer form a power core unit, at least one power core unit is included, and a control core tensile unit is arranged near the power core unit(s). Thus, the tensile capability of a control core is high, the cable is effectively prevented from being broken when the coal cutter moves and bends, and the service life of the cable is long.

Description

technical field [0001] The invention relates to a cable, in particular to a coal shearer cable. Background technique [0002] At present, the cables used in the operation of the shearer will move with the shearer, so the power core and the control core are generally arranged in the same cable structure. According to the current requirements, the control wire core only needs a small cross-section, but during the use of the cable, the cable moves frequently with the movement of the shearer, and the control wire core cross-section is small, so there is a problem in the frequent movement and bending. It may be pulled off, so that it cannot play the role of control and monitoring. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a control wire core with strong tensile strength, which can effectively prevent the cable from being broken when the shearer moves and bends, and has ...
