Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Examples
Referring to fig. 1, in an embodiment of the present invention, an automatic cable following towing device for a fully-mechanized excavating machine is characterized in that: the comprehensive digging machine comprises a fixed pulley seat 1, a fixed pulley 2, a traction steel wire rope 3, a movable pulley 4, a cable dragging wheel 5, a cable clamp 6, a wire pressing device 7, a cable 8 and a comprehensive digging machine 9; the fixed pulley seat 1 is fixedly arranged on the wall of the coal mining roadway, and the fixed pulley 2 is rotatably arranged on the fixed pulley seat 1; the movable pulley 4 is fixedly connected with a towing wheel 5 relatively, the cable clamp 6 is wound on the towing wheel 5, the cable 8 is arranged in the cable clamp 6, one end of the cable 8 close to the roadheader 9 is connected with the wire pressing device 7, and the wire pressing device 7 is fixedly installed on the roadheader 9; the traction steel wire rope 3 sequentially bypasses the fixed pulley 2 and the movable pulley 4, one end of the traction steel wire rope 3 is fixedly connected with the fully-mechanized excavating machine 9, and the other end of the traction steel wire rope is fixed on one side of the coal mining roadway far away from the working face.
Specifically, two fixed pulleys 2 are arranged, one fixed pulley is fixedly arranged on one side of the coal mining roadway close to the working face, and the other fixed pulley is fixedly arranged on one side of the coal mining roadway far away from the working face, so that the direction of the fully-mechanized excavating machine 9 can be changed through the traction steel wire rope 3.
Specifically, the radius of the towing wheel 5 is greater than or equal to the minimum bending radius of the cable 8, so as to prevent the cable 8 from being excessively bent to cause damage.
Specifically, the fixed pulley seat 1 is hinged to the fixed pulley 2 through a pin shaft.
Specifically, the automatic cable following dragging device of the roadheader further comprises a tension sensor 10, one end of the tension sensor 10 is fixed to the roadheader 9, and the other end of the tension sensor 10 is detachably and fixedly connected with the cable 8; the output end of the tension sensor 10 is electrically connected with the electric cabinet of the roadheader 9. When the towing wheel 5 encounters an obstacle and the pulling force of the towing cable 8 is too large, in order to prevent the cable 8 from being damaged due to the too large pulling force, the tension sensor 10 can act when the pulling force exceeds a certain value, and then the comprehensive excavator 9 stops working instantly to protect the cable 8 from being damaged.
The use process comprises the following steps:
when the comprehensive excavator 9 is located on a working face for ascending coal mining, the comprehensive excavator 9 drags the traction steel wire rope 3 through the machine body, the traction steel wire rope 3 drags the movable pulley 4 to rotate through the two fixed pulleys 2 and to ascend along with the comprehensive excavator 9, then the dragging cable wheel 5 is driven to move upwards, finally the cable 8 is driven to ascend, and automatic towing cable ascending of the comprehensive excavator is achieved. When the towing wheel 5 encounters an obstacle and the pulling force of the towing cable 8 is too large, in order to prevent the cable 8 from being damaged due to the too large pulling force, the tension sensor 10 can act when the pulling force exceeds a certain value, and then the comprehensive excavator 9 stops working instantly to protect the cable 8 from being damaged.
In the process, the arrangement of the fixed pulley seat, the fixed pulley, the traction steel wire rope, the movable pulley, the cable dragging wheel and the cable clamp effectively ensures that the cable automatically follows the machine and synchronously walks with the comprehensive digging machine; through the arrangement of the tension sensor, the condition that the cable is damaged due to overlarge dragging tension is effectively prevented; the application has the advantages of simple structure, strong practicability and simple operation and is worth popularizing.
The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
