Description
Technical field
The utility model belongs to the conveyer of mining machinery, is mainly used in belt conveyer.Be specifically related to a kind of without friction Centrifugal Back Idler.
Background technology
Along with continuing to increase of coal underground mining, the Application of the long distance in down-hole, high spud angle, large conveying quantity more and more comes extensively, some belt conveyers inclination angle surpasses 30 °, and when large inclination belt conveyor stops due to a variety of causes heavy duty, system occurs that reverse trend is inevitable.The method of traditional anti-check of belt conveyer is generally the driver element at conveyer, and the holdback of respective model is installed in the shaft extension of the high speed shaft of reductor or the shaft extension of slow-speed shaft or head roll.Once yet holdback lost efficacy, gently cause supports for material down-sliding damage equipment, heavy cause great personal casualty.
Simultaneously, the application of Non-return idler is also increased, and its back-stop mechanism of the Non-return idler that ore deposit side is generally used is welded on roller carrier shaft, and position is flat vertical with axle, back-stop mechanism is motionless, and the block that is welded in roller skin by carrying roller when reversion back-stop mechanism blocks and plays non-return effect.
The shortcoming that this Non-return idler exists: 1. carrying roller often rotates a circle, back-stop mechanism and block collision 2 times, the sound that sends dingdingdangdang in service; 2. when the upper fortune inclination angle of belt conveyer reaches more than 30 °, because back-stop mechanism does not contact and loses non-return effect with block when carrying roller reverses.
Summary of the invention:
The utility model aims to provide the defect for traditional Non-return idler, utilizes centrifugal principle, simple in structure, rotates flexibly, and inverse-stopping functions failure-free is a kind of without friction Centrifugal Back Idler.
The utility model comprises carrying roller, roller carrier shaft, block, back-stop mechanism, and carrying roller is arranged on roller carrier shaft by bearing, and block is welded on roller carrier shaft, and back-stop mechanism is arranged between carrying roller and roller carrier shaft and with carrying roller and welds;
Described back-stop mechanism comprises check plate, apart from piece, locating plate, check plate and being all fixed between two locatings plate apart from piece, wherein check plate is separately fixed at the upper and lower position of locating plate, is separately fixed at the left and right position of locating plate apart from piece.
Principle of work of the present utility model is: when carrying roller main story, because back-stop mechanism is very light, under the effect of centnifugal force, back-stop mechanism is attached on carrying roller wall, does not contact with the block being welded on axle; When carrying roller reversion, back-stop mechanism falls after rise with block under Action of Gravity Field collides and plays non-return effect.
Of the present utility model simple in structure, rotate flexibly, cost is low, inverse-stopping functions is reliable, be applied on fortune conveyer, especially on high spud angle, transport on conveyer and can actv. to prevent that conveyer that belt conveyer causes due to a variety of causes such as power-off from reversing and the load-transfer device that causes due to broken belt glides, improve the safety in production level of belt conveyer.

In figure, 1. block, 2. back-stop mechanism, 3. roller carrier shaft, 4. carrying roller, 5. rivet, 6. locating plate, 7. pad, 8. check plate, 9. apart from piece, 10. check place-limited edge, 11. check position-limited troughs, 12. sphenocephalies.
The specific embodiment:
Embodiment mono-: shown in Fig. 1, Fig. 2, the present embodiment is comprised of carrying roller 4, block 1 and back-stop mechanism 2.
Block 1 is welded on roller carrier shaft 3, and the check place-limited edge of block 1 is flat vertical with the axle of roller carrier shaft, and back-stop mechanism is welded on carrying roller inwall.
Shown in Fig. 3, the cross-sectional plane of block 1 is annular, and a side outer wall of block 1 is provided with protruding check place-limited edge 10, forms check position-limited trough 11 between check place-limited edge 10 and outer wall.
Check position-limited trough 11 coordinates with sphenocephaly 12 can stop carrying roller reversion.
Shown in Fig. 4, Fig. 5, back-stop mechanism is comprised of apart from piece 9, two 6,4 rivets 5 of locating plate and two pads 7 two blocks of check plates 8, two, two check plates 8 and two are clipped between two locatings plate 6 apart from piece 9, wherein two check plates 8 are fixed on respectively the upper and lower position of locating plate with rivet, between rivet and check plate 8, be lined with 7, two, pad and with rivet, be fixed on respectively the left and right position of locating plate apart from piece 9.
Locating plate 6 cross-sectional planes are annular arrangement.
One end of check plate 8 is sphenocephaly, and sphenocephaly coordinates with the check position-limited trough 11 of block.
