Abstract
A kind of mining cable, comprise metal core, the core rubber layer wrapped outside metal core, be set in the core rubber layer outer end metal armor of undulate and the external insulation rubber layer that is arranged at outside metal armor along its length, in described external insulation rubber layer, be provided with some fixed blocks along its length.When there is bending in cable in process of deployment, the external insulation rubber layer flexural deformation of crooked position outer end, length, because the chute of crooked position outboard end bends simultaneously time bending, therefore the relative chute of sliding shoe is fixed, now the metal armor of outboard end is stretched, and the outer diameter length compression of crooked position medial extremity diminishes, in BENDING PROCESS, sliding shoe slides along chute to the direction of contiguous fixed block, the now crooked position medial extremity compression of metal armor, the flexibility of its wave position strengthens.Follow deformation by metal armor when cable bend, can guarantee that, when cable bend, metal armor is not fractureed.
Description
Technical field
The utility model relates to field of cable technology, is specifically related to a kind of mining cable.
Background technology
As everyone knows, coal mine roadway is cranky, therefore when mining cable is laid in coal mine roadway, very easily occur to lose money in business completely, the metal armor layer of existing mining cable easily fractures when cable bend, because ore deposit environment is badly high to cable shield performance requirement, the cable after therefore fractureing cannot use, thus causes the difficulty of construction and the cost up of cable laying.
Summary of the invention
The utility model in order to overcome the deficiency of above technology, provide a kind of when effectively preventing cable from losing money in business metal armor layer there is the mining cable of fracture.
The utility model overcomes the technical scheme that its technical problem adopts:
This mining cable, comprise metal core, wrap the core rubber layer outside metal core, be set in the core rubber layer outer end metal armor of undulate and the external insulation rubber layer that is arranged at outside metal armor along its length, some fixed blocks are provided with along its length in described external insulation rubber layer, external insulation rubber layer between described every two fixed blocks is provided with chute, sliding shoe is slidably mounted in chute, described fixed block is fixed on a crest place of corrugated metal armor, two sliding shoes adjacent with fixed block left and right are individually fixed in two the crest places being positioned at two ends, fixed block left and right of metal armor.
For the ease of return, also comprise two ends be connected on fixed block and sliding shoe in the forniciform elastic wire of circular arc, the bend of described elastic wire towards metal core, when elastic wire is in free state, described metal armor undulate along its length.
The beneficial effects of the utility model are: when bending occurs cable in process of deployment, the external insulation rubber layer flexural deformation of crooked position outer end, length, because the chute of crooked position outboard end bends simultaneously time bending, therefore the relative chute of sliding shoe is fixed, now the metal armor of outboard end is stretched, and the outer diameter length compression of crooked position medial extremity diminishes, in BENDING PROCESS, sliding shoe slides along chute to the direction of contiguous fixed block, the now crooked position medial extremity compression of metal armor, the flexibility of its wave position strengthens.Follow deformation by metal armor when cable bend, can guarantee that when cable bend, metal armor is not fractureed, and improves the reliability of cable laying work, reduces cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1. metal core 2. core rubber layer 3. metal armor 4. fixed block 5. sliding shoe 6. chute 7. external insulation rubber layer 8. elastic wire.
Embodiment
Be described further below in conjunction with accompanying drawing 1 pair of the utility model.
This mining cable, comprise metal core 1, wrap the core rubber layer 2 outside metal core 1, be set in the core rubber layer 2 outer end metal armor 3 of undulate and the external insulation rubber layer 7 that is arranged at outside metal armor 3 along its length, some fixed blocks 4 are provided with along its length in external insulation rubber layer 7, external insulation rubber layer 7 between every two fixed blocks 4 is provided with chute 6, sliding shoe 5 is slidably mounted in chute 6, fixed block 4 is fixed on a crest place of corrugated metal armor 3, two sliding shoes 5 adjacent with fixed block about 4 are individually fixed in two the crest places being positioned at fixed block about 4 two ends of metal armor 3.When there is bending in cable in process of deployment, external insulation rubber layer 7 flexural deformation of crooked position outer end, length, because the chute 6 of crooked position outboard end bends simultaneously time bending, therefore chute 6 is fixing relatively for sliding shoe 5, now the metal armor 3 of outboard end is stretched, and the outer diameter length compression of crooked position medial extremity diminishes, in BENDING PROCESS, sliding shoe 5 slides along chute 6 to the direction of contiguous fixed block 4, the now crooked position medial extremity compression of metal armor 3, the flexibility of its wave position strengthens.Follow deformation by metal armor 3 when cable bend, can guarantee that when cable bend, metal armor 3 is not fractureed, and improves the reliability of cable laying work, reduces cost.
Also comprise two ends be connected on fixed block 4 and sliding shoe 5 in the forniciform elastic wire 8 of circular arc, the bend of elastic wire 8 towards metal core 1, when elastic wire 8 is in free state, metal armor 3 undulate along its length.Elastic wire 8 can cable in bending state time stretch, when straightened condition replied by cable, elastic wire 8 provides elastic force to pull rapidly sliding shoe 5 along chute 6 rollback, makes it rapidly recover original state, further increases the useful life of cable.
