The invention provides an intelligent control device and method for a power supply cable of a coal mining machine, and belongs to intelligent control devices and methods of the coal mining machine. The intelligent control device for the power supply cable of the coal mining machine is composed of a machine-borne cable deploying and retracting control device, ground cable protection control devices and a cable groove. The machine-borne cable deploying and retracting control device is mounted on the coal mining machine. The power supply cable led out from the cable groove is connected into the machine-borne cable deploying and retracting control device. Two sets of ground cable protection control devices are arranged and are mounted on the two sides of a traveling track of the coal mining machine respectively. The ground cable protection control devices and the machine-borne cable deploying and retracting control device conduct coordination control in a communication mode. Burdensome cable laying work is avoided, the safety of the cable can be guaranteed, and the danger of detonating gas or coal dust in special environments is removed. The intelligent control device and method for the power supply cable of the coal mining machine have the advantages that the automation degree of a matched device of the coal mining machine is improved, a condition is created for efficient and safe mining, power can be supplied to the coal mining machine conveniently and safely, breakage faults occurring to the cable are prevented, and the electric safety and efficient mining are guaranteed.
Description
technical field [0001] The invention relates to an intelligent control device and method for a power supply cable of a coal shearer, in particular to a mobile power supply device and method for a coal shearer. Background technique [0002] Both the movement and coal cutting of the coal shearer need to provide electric energy, and the power supply of the coal shearer is usually supplied by the mobile substation through cables to the coal shearer. There are currently two methods of laying cables from the mobile substation to the coal shearer. One is to hang the cable on the pulley through the roof pulley for power supply; the other is to lay the cable through the bottom groove of the scraper conveyor. cable. But no matter which method is used, the cable will be rubbed when the shearer is moving, which is particularly easy to cause damage to the cable, which not only affects the power supply, but also the damaged cable is easy to generate sparks, detonate gas or coal dust, and...
