Description

Belt conveyer edger roll

Technical field

The utility model relates to a kind of belt conveyer edger roll.

Background technology

In belt conveyer operational process, often there will be the problem of sideslip, in order to prevent the generation of deviation phenomenon, conventionally in load-transfer device both sides, edger roll is set, edger roll is to arrange in the belt lateral surface mode vertical with belt, and in market, common edger roll is cylindrical cartridge type structure, so will often there is sideslip in the belt on edger roll, once when belt generation sideslip, some edger rolls on market can only stop belt to continue sideslip, and can not correct sideslip; In addition, edger roll adopts steel pipe to process more, and along with the growth of period of service, the tube wall of steel pipe is wearing and tearing constantly, such edger roll not only service life short, and its fray can become very sharp, like this with regard to as easy as rolling off a log damage belt.

Summary of the invention

The problem existing for above-mentioned prior art, the utility model provides a kind of belt conveyer edger roll, can, to backhaul application force of belt in the time of belt generation sideslip, correct the sideslip of belt; Meanwhile, the pipe box of edger roll adopts wear resistant nylon material, has not only extended service life, even and there are wearing and tearing, its fray is also more mellow and fuller, can prevent that belt is subject to scratch.

To achieve these goals, the utility model provides a kind of belt conveyer edger roll, comprise rotating shaft, be sleeved on the pipe box on head bearing and lower bearing, the upper end of rotating shaft be equipped with successively to outside by inboard upper gasket, head bearing, on back-up ring, upper cover, bolt washer, bolt, lower end in rotating shaft is equipped with lower gasket, lower bearing, lower back-up ring, lower capping successively to outside by inboard, longitudinal surface of described pipe box is the thick circular arcs in middle thin two ends.

Further, described pipe box is that wear resistant nylon material is made, and the thickness of this pipe box thinnest part is not less than 15mm.

Further, between described pipe box and rotating shaft, formed the toroidal cavity of fat sealing.

The utility model, by making edger roll longitudinally become the thick circular arc in middle thin two ends in surface, can, in the time of belt generation sideslip, be corrected the sideslip of belt, makes belt recover normal operation; In addition, pipe box adopts wear resistant nylon material to make, and can prevent from bringing damage because of the wearing and tearing due to self in pipe box use procedure to belt.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the scheme of installation that vertical rod symmetry of the present utility model is arranged on the both sides of belt;

Fig. 3 is the schematic diagram that the utility model is corrected belt deviation.

In figure: 1, rotating shaft, 2, pipe box, 3, upper gasket, 4, upper cover, 5, lower capping, 6, head bearing, 7, bolt, 8, bolt washer, 9, upper back-up ring, 10, toroidal cavity, 13, lower gasket, 16, lower bearing, 19, lower back-up ring.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

If Fig. 1 is to as shown in Fig. 3, a kind of belt conveyer edger roll, comprise rotating shaft 1, be sleeved on the pipe box 2 on head bearing 6 and lower bearing 16, the upper end of rotating shaft 1 be equipped with successively to outside by inboard upper gasket 3, head bearing 6, on back-up ring 9, upper cover 4, bolt washer 8, bolt 7, lower end in rotating shaft 1 is equipped with lower gasket 13, lower bearing 16, lower back-up ring 19, lower capping 5 successively to outside by inboard, longitudinal surface of described pipe box 2 is the thick circular arcs in middle thin two ends.

Because after the long-time use of pipe box 2, its surface there will be the phenomenon of wearing and tearing, scratch belt after its fray contacts with the outer rim of belt, in order to prevent the generation of this phenomenon, and can better increase the friction force of pipe box 2 and belt, can make described pipe box 2 adopt wear resistant nylon material to make, the thickness of these pipe box 2 thinnest parts is not less than 15mm.

For the convenient maintenance to this edger roll, make this edger roll need not be often grease-added, can make to form between pipe box 2 and rotating shaft 1 toroidal cavity 10 that fat seals.

This edger roll is contained in the belt both sides on belt conveyer symmetrically, and place of the longitudinal center of edger roll contacts with the outer rim of belt, because pipe box 2 is the thick circular arcs in middle thin two ends, in the time there is sideslip in belt in the process of operation, pipe box 2 can be in the part contacting with belt outer rim, form one with the backhaul power F of belt deviation opposite direction, under the effect of backhaul power F, belt can be corrected on normal track gradually; In order to make backhaul power F large as much as possible, can select the material that skin friction force is larger to make pipe box 2, so just can make faster belt return on normal orbit works, preferably select wear resistant nylon material to make pipe box 2, in the time selecting wear resistant nylon material, even if there is the situation that surface is worn after the long-time use of pipe box 2, also can not cause to belt the infringement of scratch.In addition, be provided with upper cover plate 4 and lower cover 5 by the both ends of the surface between pipe box 2 and rotating shaft 1, thereby formed the toroidal cavity 10 of fat sealing, like this, can be in toroidal cavity 10 the disposable grease that fills, just can often safeguard this edger roll grease up.
