Special cable for intelligent coal mining machine

Abstract

The invention discloses a special cable for an intelligent coal mining machine, which comprises a power line, a control line, a communication line, an optical fiber, a grounding line, an air pipe andan insulating jacket, a zipper mechanism is arranged on the insulating jacket, and the insulating jacket is closed by the zipper mechanism to form an insulating sleeve; and the power line, the controlline, the communication line, the optical fiber, the grounding line and the air pipe are arranged in an inner cavity of the insulating sleeve, the air pipe is arranged in the middle of the insulatingsleeve, and a foam extrusion filling layer is arranged on the inner wall of the insulating sleeve. The insulating outerjacket is provided with an anti-disengaging and anti-abrasion accessory, the anti-disengaging and anti-abrasion accessory comprises a tightening ring strip fixedly arranged on the insulating outer sleeve in a sleeving mode, the tightening ring strip is provided with a plurality of supporting rolling pieces, and the tightening ring strip is fixed through a positioning mechanism to form a positioning ring arranged on the insulating outer sleeve in a sleeving mode. And the insulating jacket is provided with a positioning hoop mechanism. Various lines are integrated, various requirements of the coal mining machine are met, and the anti-abrasion device has the advantage of being good in anti-abrasion effect.

Description

technical field [0001] The invention relates to the field of mining, in particular to a special cable for an intelligent shearer. Background technique [0002] In the process of intelligent coal mining, the intelligentization of the key equipment coal mining machine is the basis of intelligent coal mining. The existing coal machine cables can no longer fully meet the transformation of on-site intelligent operation, and various lines are arranged separately. , It is easy to cause entanglement, and it is easy to cause friction with the inner wall of the pipe during traction and laying, causing damage. Therefore, we provide a special cable for intelligent shearer. Contents of the invention [0003] In order to solve the defects in the prior art, the invention provides a special cable for an intelligent shearer. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0005] The present ...
