Abstract

The utility model discloses a friction reverse stopping roller, which comprises a roller body and a fixing bracket on the both end thereof, the center of the roller body pulls on and loads the roller axle, a bearing is arranged between the inner wall of the roller body and the roller axle, the two ends of the roller axle are fixed on the fixing bracket after going through the bearing. A reverse stopping device is arranged on the roller body. The reverse stopping device comprises a one-way bearing mounted on the roller and the stopping parts connected with the one-way bearing. Adopting the technical proposal in the utility model, when tape breaks or the reverse stopping device invalidating adhesive tape slides down, the sliding down adhesive tape bring the roller reverse turning, as the one-way rotating performance of the one-way bearing mounted on the roller axle, the stopping parts of reverse turning plate connected with the one-way bearing turns under the driving of the reverse stopping device along with the roller reverse turning, when the reverse turning plate turns to the direction above position of the roller, the sliding block comes up against the positioning block, the reverse turning plate stops turning, and then the sliding force of material and the adhesive tape is balanced by the friction between the adhesive tape and the reverse turning plate as well as the slant component force, the adhesive tape does not slide any more.

Description

The friction Non-return idler

Technical field

The utility model relates to the friction Non-return idler that uses on a kind of belt conveyer.

Background technology

The corresponding large-scale fortune inclination angle of going up is at 12～30 belt conveyer, if broken belt takes place or holdback lost efficacy, adhesive tape and material will glide and damage transportation device, obstruction tunnel, even cause great personal casualty, and consequence is very serious.

Large-scale upper conveying belt type conveyer broken belt has following characteristics: 1, broken belt point is uncertain in practice; 2, adhesive tape and material by gravity can glide behind the broken belt; 3, the broken belt accident is huge to damage of facilities, and is huge to producing influence; 4, between the common carrying roller check not, adhesive tape and carrying roller is the friction of rolling that line contacts, and friction coefficient is very little, and slip velocity can be more and more faster behind the broken belt.It is very necessary that therefore the actv. non-return device is installed on large-scale upper conveying belt type conveyer.

Summary of the invention

The purpose of this utility model provides a kind of Non-return idler that rubs safely and effectively.

For achieving the above object, the utility model adopts following technical scheme: a kind of friction Non-return idler, the fixed support that comprises carrying roller body and its two ends, carrying roller body center installs roller carrier shaft, be provided with bearing between carrying roller body inwall and roller carrier shaft, the roller carrier shaft two ends are fixed on the fixed support after passing bearing, and roller carrier shaft is provided with non-return device, and described non-return device comprises unilateral bearing that is installed on the roller carrier shaft and the stop part that links to each other with unilateral bearing.

Described unilateral bearing is the roller type one way bearing that is installed on the roller carrier shaft, and described stop part is the turnover panel that is fixed on the unilateral bearing outer ring.

Described roller type one way bearing has two, and symmetry is positioned at the roller carrier shaft both ends, and described turnover panel is the gate-type structure, and two ends are separately fixed on two unilateral bearing outer rings.

In order to increase friction force, the panel of described turnover panel is a double-decker, and skin is the pattern rubber plate.

Adopt technical scheme described in the utility model, when the downslide of broken belt or holdback inefficacy adhesive tape takes place when, the downslide adhesive tape drives the carrying roller contrarotation, because the unidirectional rotatory of unilateral bearing on the roller carrier shaft, the stop part that links to each other with unilateral bearing be turnover panel under non-return device drives also with the carrying roller contrarotation, in the time of directly over turnover panel rotates to the holder rod, slide block is run into locating piece, turnover panel stops operating, this moment, the sliding force of material and adhesive tape was offset by friction force between adhesive tape and the turnover panel and oblique component, and adhesive tape no longer glides.

The specific embodiment

Shown in Fig. 1,2 and 3, the utility model comprises the fixed support 1 at carrying roller body 4 and its two ends, carrying roller body 4 centers install

roller carrier shaft

2,2 of carrying roller body 4 inwalls and roller carrier shafts are provided with bearing 7, roller carrier shaft 2 two ends are fixed on the fixed support 1 after passing bearing 7, roller carrier shaft 2 both ends symmetry respectively install a roller type one way bearing 3, unilateral bearing 3 inner rings link to each other with carrying roller body 4 sidewalls, unilateral bearing 3 outer rings are fixed with the turnover panel 5 of gate-type structure, the panel of turnover panel 5 is a double-decker, and skin is a pattern rubber plate 6.

This friction Non-return idler is installed on the crossbeam of belt conveyer carrying roller group, in installation shown in Figure 4 among the load-transfer device normal operating condition figure of the present utility model, adhesive tape 8 moves obliquely upward and transmits material, and the turnover panel 5 on the carrying roller body 4 below this moment adhesive tape 8 is positioned at the oblique upper parallel with adhesive tape 8.Because the unilateral bearing 3 that links to each other with carrying roller body 4 sidewalls has unidirectional rotatory, so the same support tape and weight of material of plaing a part of carrying roller of this moment with common carrying roller, under the friction force of adhesive tape 8 drives, carrying roller body 4 left-hand revolutions, and be fixed on turnover panel 5 transfixions of unilateral bearing 3 outer rings.

In installation shown in Figure 5 in the constitution diagram during load-transfer device of the present utility model fracture, adhesive tape 8 begins to glide, downslide adhesive tape 8 drives the rotation of carrying roller body 4 reverse (cws), because the unidirectional rotatory of unilateral bearing 3, the turnover panel 5 that links to each other with unilateral bearing 3 outer rings also with 4 contrarotations of carrying roller body.

In installation shown in Figure 6 in the constitution diagram after load-transfer device of the present utility model fracture and the braking, adhesive tape 8 fractures are glided and are driven the turnover panel 5 continuation contrarotations that are fixed on unilateral bearing 3 outer rings, in the time of directly over turnover panel 5 rotates to the holder rod, slide block is run into locating piece, turnover panel 5 stops operating, the cliding friction that contacts for face between this moment adhesive tape 8 and the turnover panel 5 surface detail rubber plates 6, the sliding force of material and adhesive tape 8 is offset by friction force between adhesive tape 8 and the turnover panel 5 surface detail rubber plates 6 and oblique component, and adhesive tape no longer glides.

When design material-transporting system engineering, determine to arrange the carrying roller group number of band friction Non-return idler again according to the size of check power according to the various computing check power at belt conveyer hoisting depth and inclination angle, can omnidistancely arrange, also can arrange at interval.
