The invention provides a control oil way, a cable winding device and a heading machine, and relates to the technical field of borehole operation equipment. The control oil way comprises a throttling valve, an oil inlet pipeline and an oil outlet pipeline; the throttling valve is connected between the oil inlet pipeline and the oil outlet pipeline and is used for adjusting the output flow of the control oil way; and the oil outlet pipeline is used for being connected to a motor. According to the technical scheme of the control oil way, the cable winding device and the heading machine, when oilliquid drives the motor to rotate, the output flow of the oil liquid in the whole control oil way can be controlled through the throttling valve so as to control the driving force of the oil liquid tothe motor by controlling the output flow so that the rotating speed of the motor can be effectively controlled, the cable take-up speed of the motor and the receding speed of the heading machine canbe adjusted according to the actual situation so that the motor and the heading machine can be kept in a relatively stable state, and therefore the problem that the heading machine rolls a cable due to the fact that the cable take-up speed of the heading machine and the motor is not coordinated can be solved.
Description
technical field [0001] The invention relates to the technical field of downhole operation equipment, in particular to a control oil circuit, a cable coiling device and a roadheader. Background technique [0002] The cantilever roadheader is a roadway excavation unit that can complete cutting, loading and reloading coal and rock, and can walk independently, and has functions such as spraying and dust removal. It is the most widely used roadway excavation machinery and equipment in coal mine underground production. . [0003] Yet the excavation work under the coal mine now still adopts the mode of manual dragging for the movement of the power supply cable of the cantilever type roadheader. [0004] However, this kind of dragging operation has high requirements for the operation of the staff. In fact, in actual operation, the problem that the crawler rolls the cable when the cantilever roadheader retreats often occurs, which will cause great safety for the actual work. Hidden...
