Abstract
The one-way idler comprises a shaft, a pipe body, bearing seats, bearings and seals. The invention is characterized in that the pipe body is provided with a pin boss which is provided with a pin shaft with a locking plate and a pin boss fastener block; the shaft is provided with a blocking cover of the locking plate by key joint and the blocking cover of the locking plate is provided with the fastener block. A belt conveyor adopts the idler can prevent fractured rubber belt form gliding and reversing.
Description
The utility model belongs to a kind of One-way cradle roll.
At present, the carrying roller that uses on the domestic and international travelling apron is two-way carrying roller.This travelling apron with two-way carrying roller is used in mine and has a down dip the tunnel during toward aboveground fortune coal, adhesive tape is fracture in a single day, because carrying roller is a bidirectional movement, the adhesive tape of fracture glides under the effect of its deadweight and coal, the adhesive tape of fracture not only can stop up pit shaft, and will destroy all facilities of pit shaft.
Task of the present utility model provides a kind of One-way cradle roll, is used for travelling apron, prevent from effectively to be operated in coal mine have a down dip the tunnel adhesive tape when fracture takes place adhesive tape glide, prevent that simultaneously travelling apron from reversing.
Below in conjunction with the description of drawings the technical solution of the utility model.
Fig. 1. be structural representation of the present utility model.
Fig. 2. be Fig. 1. the A-A cutaway view.
Fig. 2. in the last adhesive tape of 17 expression travelling aprons, 1. → expression on service direction during the adhesive tape normal operation, 2. → direction that glides during the adhesive tape broken belt in the expression.
One-way cradle roll provided by the utility model has body 11., axle 1., bearing block 8., sealing 9., bearing 10., oil sealing 13., it is characterized in that being provided with in the body 11. the annular key seat 5. with its stationary fit, key seat 5. is provided with a bearing pin 6. near the end face of bearing block 8., bearing pin 6. is with a locking plate that can rotate around it 7., there is a key seat fixture block 15. that is located on key seat 5. end faces in locking plate 7. left sides, axle 1. is provided with a locking plate door 18. that connects with its key 12., locking plate door 18. is provided with a door fixture block 16. near the end face of bearing block 8., key seat 5. and locking plate door 18. have a gap between radially, all and bearing block 8. certain distance is arranged between axially, locking plate 7. free ends apart from the distance of axle 1. less than the distance of door fixture block 16. apart from axle 1..
Bearing pin 6. in the utility model, locking plate 7., key seat fixture block 15., door fixture block 16. can be arranged symmetrically with.
The working process of One-way cradle roll is:
When the travelling apron normal operation, last adhesive tape along 1. → the direction operation, last adhesive tape makes body 11. in the counterclockwise direction around axle 1. rotations by the surface friction of bottom surface and idler pipe 11..Because of body 11. and pin seat 5. are integral for close fit, key seat 5. is an one with bearing pin 6., and locking plate 7. can rotate around bearing pin 6., makes locking plate 7. make compound motion, be that locking plate rotates with body 11., locking plate 7. free ends rotate counterclockwise around bearing pin 6. under its action of centrifugal force simultaneously.Like this, One-way cradle roll rotates as common carrying roller.
When travelling apron broken belt or reverse, last adhesive tape just along 2. → direction glides, under last adhesive tape bottom surface and the 11. outside face friction force effects of One-way cradle roll body, body 11., key seat 5. rotate around axle 1. clockwise directions, thereby locking plate 7. are also rotated counterclockwise.When locking plate 7. forwards to when contacting with door fixture block 16., because door fixture block 16. is fixed on the locking plate door 18., locking plate door 18. connects with axle 1. by key 12., be fixed, like this, body 11., key seat 5. are under bearing pin 6., locking plate 7., key seat fixture block 15., 16. combineds action of door fixture block, can not relatively rotate around axle 1., body 11. just stops operating, thereby has realized the unidirectional rotation of carrying roller, i.e. One-way cradle roll.If travelling apron adopts this One-way cradle roll, because of the friction force of carrying roller surface and adhesive tape sliding force, so adhesive tape glides in the time of can preventing that adhesive tape from fracture taking place, and can prevent also that simultaneously travelling apron from reversing greater than adhesive tape and weight.
