[0013] The following is a further description with reference to the drawings for the convenience of those skilled in the art to understand the technical solution of the present utility model. It should be understood that these descriptions are exemplary and not intended to limit the scope of the present utility model.

[0014] In the following detailed description, for the purpose of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present utility model. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present utility model.

[0015] As Figure 1 shown, Fig. is the overall structural schematic diagram of the cable moving and hanging device for the fully-mechanized heading face of the present utility model, including a suspension steel wire rope 1, a redirecting pulley 2, a winch 3, a plurality of traction pulley assemblies 4 and a plurality of cable fixing devices 5 arranged between the roof at the heading face of the fully-mechanized heading face and the self-advancing tail.

[0016] Among them, the redirecting pulley 2 is fixed on the roof plate at the tail of the self-propelled shearer. The first end of the suspension wire rope 1 is fixed on the roof plate at the heading face of the fully mechanized heading face through an anchor bolt. The second end of the suspension wire rope 1 is wound around the redirecting pulley 2, and the end of the suspension wire rope 1 is stranded in the winch 3. A number of traction pulley assemblies 4 are suspended on the suspension wire rope 1 at intervals. Specifically, when implemented, there is a suspension position every 1.2 m to 1.8 m on the suspension wire rope 1. The traction pulley assembly 4 includes a wheel body 41 and a clamping groove 42 provided on the wheel body. The clamping groove 42 is fixedly arranged on the suspension wire rope 1, and the extended part of the cable 6 passes through the clamping groove 42 in a wavy shape in sequence. A number of cable fixing devices 5 are arranged at intervals, and their tops are fixedly sleeved on the suspension wire rope 1, and their bottoms extend to the bottom of the cable 6 to hang up the bottom end of the cable 6.

[0017] As Figure 2 shown, it is a schematic diagram of the overall structure of the cable fixing device of the present invention. Specifically, when implemented, the cable fixing device 5 includes a fixed straight plate 51. The top of the fixed straight plate 51 is provided with a first arc-shaped limiting groove 52. The first arc-shaped limiting groove 52 is sleeved on the suspension wire rope 1, and the bottom of the first arc-shaped limiting groove 52 is sealed by a bolt 53. One side of the bottom end of the fixed straight plate 51 is bent towards the other side and provided with an arc-shaped hanging plate 54.
