Technical Field

[0001] The utility model relates to the field of cable fixing, in particular to a cable fixing mechanism for a coal mining machine. Background Art

[0002] Coal mining machine is one of the main equipment of comprehensive mining equipment. It is developed from coal cutting machine. Coal mining machine is a large and complex system integrating mechanical, electrical and hydraulic systems. It is one of the important equipment for realizing the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve the goals of high output, high efficiency and low consumption.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] When it is necessary to fix the head end of the cable, first pass the cable through the inner middle part of the movable cylinder 7, and then twist the multiple sets of fixing bolts 12 at both ends of the movable cylinder 7 to adjust the size of the circle formed by the three sets of clamps 11. When the three sets of clamps 11 are closed inwardly, the cable passing through the movable cylinder 7 can be clamped and fixed, and then the movable cylinder 7 is slidably installed into the inner middle part of the sleeve 5 for limiting the position. At the same time, a spring 9 is arranged between the movable cylinder 7 and the sleeve 5. When the cable is subjected to external tension and drives the movable cylinder 7 to slide horizontally in the inner middle part of the sleeve 5, the spring 9 can buffer the tension on the cable, thereby avoiding the interface between the cable and the coal mining machine from being subjected to hard pulling, which causes the cable to fall off.

[0024] Then, the fixing mechanism can be limitedly installed on the coal mining machine through the mounting seat 1, and by setting a rotating shaft 3 between the mounting seat 1 and the support column 2, the support column 2 can drive the sleeve 5 to rotate 360 ​​degrees in the middle of the upper end of the mounting seat 1, thereby avoiding the situation where the cable is stuck due to angle problems during the pulling process.
