Background Art
[0002] In coal mining, shearers rely on tow cables to provide power and signal transmission support for the coal cutting tools. However, during the reciprocating movement of the shearer, the tow cables are easily damaged by wear, bending, or jamming, affecting equipment efficiency and even causing production stoppages. Currently, the tow cable systems used in most mines rely on fixed guide frames or pulley systems to achieve directional cable transmission. The basic principle is to install a series of fixed guide structures (such as metal brackets and roller pulleys) above or to the side of the shearer's movement path. These structures constrain and guide the tow cables, forcing them to move in a predetermined direction. However, traditional fixed tow cable guide systems cannot adjust in real time based on the tow cable's status, which can easily lead to uneven force or local overload on the tow cables. Furthermore, when encountering complex mine terrain and frequent directional changes of the shearer, the system cannot flexibly adjust, resulting in the tow cables being frequently over-bent or stretched, which accelerates their damage. In addition, most existing tow cable guide systems only provide basic physical constraints and lack the ability to monitor key parameters such as tow cable force and position offset in real time. When the tow cable is overloaded or in an abnormal state, it is impossible to issue a warning signal in time or take proactive adjustment measures, which can easily lead to equipment failure or even safety hazards.

[0013] The present invention also relates to a method for using a shearer towline guide device based on dynamic induction control, the method comprising the following steps: (1) Equipment inspection and preparation: Ensure that all parts are installed correctly and operate normally. Check whether the cable drag track, guide groove (6) and three-pulley tension sensor are installed in place and ensure that they are not loose or damaged. Check whether the data cable connections of the signal transmission module (9), micro camera (8), control module (4), etc. are correct and confirm that their communication functions are normal. (2) Initialization settings: Turn on the power switch to start the processing module and control module (4) in the fixed box (1), wait for the system to complete the self-test and load the initial parameters (initial position of the pulley (20) and tension threshold, etc.), and set the working mode (automatic adjustment or manual adjustment) and alarm threshold of the dynamic control component through the processing module; (3) When the coal mining machine body (2) moves on the track (3), the cable (7) is dragged by the body (2) and moves within the cable dragging track. The three-pulley tension sensor monitors the tension change of the cable (7) in real time and transmits the signal to the signal transmission module (9) through the data line. At the same time, the micro camera (8) shoots the cable (7) on the pulley (20) and transmits the image signal to the signal transmission module (9); (4) After the signal transmission module (9) performs signal conversion, the signal is transmitted to the processing module. After receiving the tension signal and the image signal, the processing module analyzes the tension change and position state of the cable (7). If it is detected that the tension of the cable (7) exceeds the set threshold, the processing module sends an adjustment instruction to the servo motor (10) through the control module (4). The servo motor (10) drives the turntable (11) to rotate. The turntable (11) drives the second connecting rod (22), the first connecting rod (13), the first connecting block (12), and the second connecting block (14) to rotate, thereby adjusting the rotation angle of the transfer box (15), thereby changing the position of the end effector (17) so that the cable (7) will not be too loose or too tight. At the same time, the processing module sends an alarm instruction to the sound and light alarm (5) through the control module (4) to remind the operator to pay attention to the state of the cable (7) until the tension of the cable returns to the threshold range. The servo motor rotates to drive the end effector (17) to reset; (5) If the image detection finds that the cable (7) deviates from the center position of the pulley (20), the processing module sends an adjustment instruction to the rotating motor through the control module (4), and the rotating motor drives the end effector (17) to rotate by 30-55 degrees, so that the pulley (20) tilts and the cable (7) slides toward the center of the pulley (20). At the same time, the processing module sends an alarm instruction to the sound and light alarm (5) through the control module (4) to remind the operator to pay attention to the status of the cable (7), until the position of the cable returns to the center position of the pulley (20), and the rotating motor rotates to drive the end effector (17) to reset; (6) The operator can view the equipment operating status (such as pulley position, tension value, etc.) in real time through the signal transmission module or external display screen, and perform manual intervention when necessary. (7) When the coal mining machine completes the operation, stop moving and cut off the power supply to ensure that the cable is completely relaxed to prevent the device from continuing to operate without supervision or causing accidental damage. Check whether the dynamic control components have returned to their initial state to ensure that the equipment is in safe shutdown mode. Example 2
