Description
Affiliated technical field
The utility model relates to the load-transfer device of belt conveyer, particularly a kind of fire retarding conveying band that is suitable for coal mine downhole safety transportation usefulness.
Background technology
At present, the fire retarding conveying band of underground mine use is to adopt whole core PVC, PVG band and rope belt.Rope belt is the warp-wise skeleton with the Steel cord, the intensity height, and load carrying ability is big, but the cost height, weight is big, easily longitudinal tear.The belt carcass of PVC, PVG band is the integral weaving structure, and the warp of belt carcass and curvature of parallel, cotton rope rate of utilization of strength are low, and tensile strength is low, and elongation is big after the tension, and rubber cover is easy to wear, and the life-span is short.
In order to solve the deficiency that the belt carcass fabric cotton rope rate of utilization of strength with fire retarding conveying band is low under the existing well, pulling strengrth is low, the tension elongation is big, the life-span is short, the utility model provides a kind of fire retarding conveying band, it not only meets fire-retardant and antistatic requirement, can also improve belt carcass fabric cotton rope strained condition, have that pulling strengrth height, tension percentage elongation are little, dynamic fatigue resistance can be good, shock resistance and tear resistance is good, the life-span is long advantage.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
The flame-proof elastomer that forms by belt carcass, belt carcass dipping thickener, fire-retardant in rubber cover and the fire-retardant down fire retarding conveying band that rubber cover constitutes, its belt carcass employing is directly through the integral weaving structure; That is: belt carcass is made of warp, parallel and connection warp; Warp linearly, straight arrangement, parallel linearly, be positioned at the upper and lower surface of warp, and straight arrangement vertical with warp, connect warp between warp, the crooked parallel that twines up and down, warp, parallel are weaved into one.The warp number of plies of belt carcass be two-layer or two-layer more than.This load-transfer device also is directly through unitary-core flame-resistant conveying belt.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted can also be:
The warp number of plies of the belt carcass of this fire retarding conveying band can adopt 2～6 layers.Its fire-retardant rubber cover of going up can adopt fire-retardant polysulphide rubbers layer, fire-retardant rubber plastic blend glue-line, fire-retardant thermoplastic elastomer with following rubber cover.The fire-retardant thermoplastic elastomer that adopts can be: fire-retardant PVC layer, fire-retardant layer of polyurethane.
The beneficial effects of the utility model are:
1. straight warp through whole belt core is a straight line, can bear pulling force well, and the pulling strengrth height is avoided the crooked big shortcoming of extending after line drawing; Because the improvement of load-transfer device warp and parallel strained condition has reduced frictional heat catabiosis between belt carcass and sizing material, has improved the dynamic fatigue resistance energy, increases the service life.Parallel is straight to be arranged in the two sides of warp, both for fabric provides necessary rigidity, again warp is played lining and protective effect.Shock-resistant and tear resistance is good, can improve joint performance, vertically subduing property and horizontal flexibility.
2. directly the connection warp through whole belt core is crooked significantly, for fabric causes high protruding indentation, has increased the area of contact between belt carcass and the flame retardant glue material, improves bond strength.
3. directly little, in light weight through whole belt core thickness.
