[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 5As shown, the utility model provides an extreme cold resistant fully injection molded electric shovel wire rope, comprising sisal strands 1, the number of sisal strands 1 is seven, the central strand is a central sisal yarn fiber core and six anti-wear sisal yarn fiber outer cores, the inner layer strands 2 are spirally twisted in the gaps between the six anti-wear sisal yarn fiber outer cores in the sisal strands 1, the number of the inner layer strands 2 is six, the outer side of the inner layer strands 2 is spirally twisted with outer layer strands 3, the number of the outer layer strands 3 is six, and the six inner layer strands 2 and the six outer layer strands 3 are spirally twisted with reinforcing steel wires 4 on one side;

[0020] A heat insulation layer 6, the heat insulation layer 6 is located outside the six outer strands 3, one side of the heat insulation layer 6 is provided with an elastic rubber layer ball 7, one side of the elastic rubber layer ball 7 is provided with a sponge layer 8, and one side of the sponge layer 8 is provided with a wear-resistant layer 9;

[0021] A flexible fiber layer 5, the flexible fiber layer 5 is filled in the gap between the inner layer strands 2 and the outer layer strands 3 and the gap between the reinforcing steel wires 4 and the thermal insulation layer 6;

[0022] When the steel wire rope is squeezed as a whole, the six sisal strands 1 are arranged outside the central sisal strand 1 to increase the overall cross-sectional area of ​​the sisal strands 1. At the same time, the six sisal strands 1 adapt to the structure of the six inner strands 2 to increase the support strength in the radial direction. At the same time, the number of the inner strands 2 and the outer strands 3 is large, and the flexibility is improved. In addition, the reinforcing steel wire 4 reduces the relative displacement between the inner strands 2 and the outer strands 3. At the same time, the flexible fiber layer 5 effectively reduces the friction of the steel wire rope.

[0023] After the steel wire rope is squeezed as a whole, its overall cross-sectional area is increased by the sisal strand 1, and the radial supporting force is increased by the cooperation of the sisal strand 1 and the inner strand 2. The friction force is reduced by the flexible fiber layer 5. Compared with the traditional device, this device reduces the friction between the steel wire ropes through the flexible fiber layer 5, thereby increasing the service life of the steel wire rope, reducing the loss, and thus reducing the noise generated by friction, so as not to affect the hearing of the residents and cause hearing loss, and also avoid the noise from affecting the nerves of the residents when they take the elevator.

[0024] Among them, the wear-resistant layer 9 is an aluminum oxide wear-resistant layer, and the heat insulation layer 6 is a basalt fiber cloth heat insulation layer;

[0025] The wear-resistant layer 9 is set to be an aluminum oxide wear-resistant layer with a thickness of one to two millimeters. The aluminum oxide wear-resistant layer has excellent wear resistance. The thermal insulation layer 6 is set to be a basalt fiber cloth thermal insulation layer. The basalt fiber cloth thermal insulation layer can effectively insulate, thereby increasing the service life of the wire rope.

[0026] The sisal strand 1 is fully soaked with lubricating grease, and the outer sides of the inner strand 2 and the outer strand 3 are coated with a zinc layer;

[0027] The sisal strands 1 are fully soaked with lubricating grease, and the steel wire rope is subjected to pressure, so that the internal friction is reduced by the lubricating grease. The outer surfaces of the inner strands 2 and the outer strands 3 are both coated with a zinc layer, which can effectively reduce the damage caused by friction.

[0028] Among them, an elastic rubber layer ball 7 is arranged between the heat insulation layer 6 and the sponge layer 8, and a sponge layer 8 is arranged between the elastic rubber layer ball 7 and the wear-resistant layer 9;

[0029] An elastic rubber layer ball 7 is arranged between the heat insulation layer 6 and the sponge layer 8, and a sponge layer 8 is arranged between the elastic rubber layer ball 7 and the wear-resistant layer 9. The coordinated use of the elastic rubber layer ball 7 and the sponge layer 8 can reduce the pressure on the wire rope, thereby increasing the service life of the wire rope.

[0030] The working principle and use process of this utility model:

[0031] When the steel wire rope is squeezed as a whole, the overall cross-sectional area of ​​the sisal strands 1 is increased by the six sisal strands 1 on the periphery of the central sisal strand 1. At the same time, the six sisal strands 1 adapt to the structure of the six inner strands 2 to increase the support strength in the radial direction. At the same time, the number of inner strands 2 and outer strands 3 is large, and the flexibility is improved. In addition, the reinforcing steel wire 4 reduces the relative displacement between the inner strands 2 and the outer strands 3. At the same time, the flexible fiber layer 5 effectively reduces the friction of the steel wire rope.
