Abstract
The utility model provides a high wear resistant supporting roller for a coal mine downhole, comprising a roller, a supporting roller shaft 3, a plastic bearing seat 4, a bearing 5, an inner retaining ring 6, an outer retaining ring 9, as well as an internal sealing member 7 and an external sealing member 8 of a labyrinth sealing device. The roller comprises a roller core and a plurality of flame retardation antistatic scrap rubber belt ferrules 1 laminated together on the roller core. The scrap rubber belt ferrules 1 are punched via flame retardation antistatic scrape rubber belts of a belt conveyer used for coal mines. The supporting roller is provided with flame retardation antistatic performance, and is suitable for a belt conveyer in gas coal dust blast dangerous environment in a coal mine downhole, the supporting roller is also advantaged by good wear resistance, capability of greatly improving service lifetime; realization utilization of mining scrap rubber belts, and change of scrap into things of value.
Description
Technical field
The utility model relates to transportation device belt conveyer under the coal mine, the underground mine use high abrasion carrying roller that has the belt conveyer that uses in the gas and dust explosion hazardous environment to use under particularly a kind of coal mine.
Background technology
Because the coal mine operation environment is abominable, the carrying roller damage rate height of belt conveyer.Wherein, snub pulley is more easy to wear, and reason is that the adhesive tape face with the snub pulley contact friction is the one side of carrying raw coal, and this face often is stained with many coal dusts, causes wearing and tearing.
The first phase that China publishes " Gazette of Patent for Invention " on July 16th, 2008 discloses title and has been: " belt conveyer rubber idler and preparation method thereof ", application number: the patent application of 200710053313.7, publication number: CN101219735A.Its objective is and utilize the scrap tire rubber circle to make wear-resisting carrying roller that both protective tapes prolongs service life of carrying roller again significantly; Its structure is the wear-resisting cushion layer of outside face that the interference suit is made up of an above scrap tire rubber circle on roller carrier shaft.Its weak point is not have the flame-retardant and anti-static performance, and can not be used for has the gas and dust explosion dangerous environment under the coal mine.
Summary of the invention
In order to solve the weak point with plastic conveyer roller wear resisting property difference of belt conveyer under the coal mine, the utility model provides that a kind of wear resisting property is good, long service life, meet the underground mine use high abrasion carrying roller of flame-retardant and anti-static requirement under the coal mine.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
Underground mine use high abrasion carrying roller is made up of roller, roller carrier shaft, plastic shaft bearing, bearing, inner shield ring, outer back-up ring, labyrinth-type excluder inner seal liner and labyrinth-type excluder outside seal may etc.Its roller is by roller tube core and be enclosed within several pieces scrap rubber lassos on the roller tube core, that be superimposed together and constitute.The scrap rubber lasso adopts flame-retardant and anti-static waste tape lasso.
The beneficial effects of the utility model are:
1. not only wear resisting property is good for this carrying roller, improves the service life of carrying roller greatly, and has the flame-retardant and anti-static performance, is adapted at having under the coal mine on the belt conveyer in the gas and dust explosion hazardous environment and uses.
2. utilize the flame-retardant and anti-static waste tape of coal mine belt conveyor to make the roller lasso, realize the utilization of a large amount of mining waste tapes, turn waste into wealth.
3. the plastic shaft bearing adopts the new fail-safe structure of removing contamination, advantages of simple more.
Description of drawings
Fig. 1 is the structural representation that adopts the underground mine use high abrasion carrying roller of plastics roller tube core.
Fig. 2 is the structural representation that adopts the underground mine use high abrasion carrying roller of steel bowl tube core.
Among the figure: 1-flame-retardant and anti-static waste tape lasso, 2-plastics roller tube core, 3-roller carrier shaft, 4-plastic shaft bearing, 5-bearing, 6-inner shield ring, 7-labyrinth-type excluder inner seal liner, 8-labyrinth-type excluder outside seal may, the outer back-up ring of 9-, 10-steel bowl tube core; The A-bulge loop.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
A kind of structure of the utility model underground mine use high abrasion carrying roller shown in Figure 1.It is made up of the inner seal liner 7 and the outside seal may 8 of roller, roller carrier shaft 3, plastic shaft bearing 4, bearing 5, inner shield ring 6, outer back-up ring 9, labyrinth-type excluder.Roller is made of plastics roller tube core 2 and several pieces flame-retardant and anti-static waste tape lassos 1 that are superimposed together that are enclosed within on the plastics roller tube core 2.Flame-retardant and anti-static waste tape lasso 1 is to utilize the waste tape punching out of the belt conveyer of underground mine use to form.This waste tape has the flame-retardant and anti-static performance.The endoporus of several pieces superimposed flame-retardant and anti-static waste tape lassos 1 and roller tube core 2 interference fit.After several pieces flame-retardant and anti-static waste tape lassos 1 were superimposed, its outside face was the face of cylinder, and their two ends are with plastic shaft bearing 4 jam-packeds.Between each sheet flame-retardant and anti-static waste tape lasso 1, between flame-retardant and anti-static waste tape lasso 1 and the roller tube core 2, also can bond with adhesive agent.
The coniform inner fovea part in outer face axle center of the plastic shaft bearing 4 of this high abrasion carrying roller, with the contact position of labyrinth-type excluder inner seal liner 7, be provided with the bulge loop A of the projection of the antifouling usefulness of a circle.
The another kind of structure of the utility model underground mine use high abrasion carrying roller shown in Figure 2.Its structure and first kind of structure are identical, and difference only is that roller tube core has adopted steel bowl tube core 10.
