Embodiment Construction
[0021] In order to make it easy to understand the technical means, creative features, achieved goals and effects of the present invention, the present invention is further described below.
[0022] like Figure 1 to Figure 7 As shown, a power supply cable protection device for a drum shearer includes a micro switch 1 , an upper cover 4 , a lower cover 6 , a safety pin 7 , a bolt 8 and a control ring 9 . The upper cover 4 is provided with a square groove 401 , the middle of the square groove 401 is provided with a No. 1 through hole 401 a , and the upper cover 4 is further provided with a blocking cover 402 , and the blocking cover 402 is located above the square groove 401 , the upper cover 4 is provided with a No. 2 through hole 403, the end surfaces on both sides of the upper cover 4 are provided with a No. 1 ring groove 404, and the middle of the upper cover 4 is provided with a No. The semicircular through slot 405 is provided with a No. 3 through hole 405a and a No. 4 th...

The invention relates to a drum shearer power supply cable protection device. The drum shearer power supply cable protection device comprises a microswitch, an upper cover, a lower cover, safety pins, bolts and a control ring. The upper cover and the lower cover are connected through the bolts. The control ring is installed in the upper cover and the lower cover. The microswitch is installed on the upper part of the upper cover, the lower part of the microswitch is fixedly connected with a spring, a steel ball is installed on the lower part of the spring, and the steel ball is attached to the surface of the control ring under the effect of the spring. The number of the safety pins is two, one safety pin is installed in the upper cover and the control ring, and the other safety pin is installed in the lower cover and the control ring. The drum shearer power supply cable protection device has the advantages that the structure design is reasonable, the cost is relatively low, etc. When a full force exceeding a maximum allowable pull force is applied to a cable, the safety pins break, the shearer stops working, the pull force is no longer applied to the cable, the protection on the cable is in time and effective, and a cable protection sheath is prevented from being torn due to a too small bending radium of a cable elbow.
Description
technical field [0001] The invention relates to the technical field of cable protection equipment, in particular to a power supply cable protection device for a drum shearer. Background technique [0002] The power supply cable of the shearer is an important part to ensure the normal operation of the shearer. During the reciprocating work of the drum shearer on the working face, the power supply cable is mainly protected and dragged by the towing device of the drum shearer. However, the working environment of the towing cable device is harsh, and sometimes the protection of the cable will fail, causing the power supply cable to be pulled. After a period of use (usually about half a month), in order to ensure the safety of the rope, the worker will replace the rope, but the replacement is a tedious process. And if the time is too long, the cable allowance at the cable elbow will be reduced, and the bending radius of the cable is too small, which may cause the cable to suffer...
