Abstract
The utility model discloses a novel non-return carrier roller, which comprises a bearing block, a non-return disc, a pin shaft, a lock sheet, a lock sheet seat, a connecting ring, roller leather, a bearing, a set bolt and a carrier roller shaft, wherein the bearing block is welded with the non-return disc, and the non-return disc is connected with the lock sheet seat through the pin shaft; the non-return disc is fixed with the lock sheet seat through the set bolt, and the lock sheet is arranged between the non-return disc and the lock sheet seat; the connecting ring is in key connection with the carrier roller shaft; and the lock sheet seat and the connecting ring are made of polymer wear-resisting materials. The novel non-return carrier roller has the advantages of reasonable structure, convenience for installation and adjustment and large born non-return torque and is safe and reliable. The novel non-return carrier roller can effectively prevent a belt conveyor from gliding and reversing during power failure or tape fracture, so that the conveyor can operate more safely and reliably.
Description
Technical field
The utility model relates to a kind of novel Non-return idler, is mainly used in belt conveyer.
Background technology
Belt conveyer is mainly by carrying roller, and support, compositions such as transfer drive, carrying roller are one of main composition parts of belt conveyer, use the most extensive.Because belt speed and freight volume is different, the oad of carrying roller is different.Carrying roller kind commonly used has: impact idler, parallel roll, aligning carrier roller etc.
At present, the belt conveyer carrying roller mainly contains following kind both at home and abroad
1. parallel roll
Be used for the return leg support belt
2. impact idler:
Be installed in material feeding section below, reduce the suffered impact of load-transfer device
3. aligning carrier roller:
Be used to adjust belt deflection
But above-mentioned all kinds of carrying rollers itself all do not have braking function, and conveyer also needs to add in addition special brake equipment and carries out the braking of equipment, and this will cause braking force to be concentrated, and can't realize the reliable parking of belt conveyer, reduce the safety of equipment.
The utility model content
The purpose of the utility model provides a kind of novel Non-return idler.
The purpose of the utility model realizes through following technical scheme:
The novel Non-return idler of the utility model comprises bearing seat, check dish, bearing pin, locking plate, locking plate seat, coupling link, roller skin, bearing, tight fixed bolt and roller carrier shaft.Bearing seat and the welding of check dish; The check dish is connected through bearing pin with the locking plate seat, and check dish and locking plate seat are fixed through tight fixed bolt, and locking plate is located between check dish and the locking plate seat; Coupling link is connected with the carrying roller axle key, and locking plate seat and coupling link adopt the high molecular abrasion-proof material to process.
Technical scheme by above-mentioned the utility model can be found out; The described novel Non-return idler of the utility model, rational in infrastructure, installation, easy to adjust; The check moment of bearing is big; Safe and reliable, downslide and reversing in the time of can preventing belt conveyer because of outage or adhesive tape fracture effectively make the conveyer operation more safe and reliable.
Description of drawings
Fig. 1 is novel Non-return idler structure diagram;
Fig. 2 is the check dish, locking plate and locking plate seat assembling scheme drawing;
Fig. 3 is a locking plate holder structure scheme drawing.
The specific embodiment
The novel Non-return idler of the utility model; The specific embodiment that it is preferable such as Fig. 1, Fig. 2, shown in Figure 3, novel Non-return idler comprise bearing seat 1, check dish 2, bearing pin 3, locking plate 4, locking plate seat 5, coupling link 6, roller skin 7, bearing 8, tight fixed bolt 9 and roller carrier shaft 10.
Bearing seat 1 and 2 welding of check dish.
Check dish 2 is connected through bearing pin 3 with locking plate seat 5, and check dish 2 is fixing through tight fixed bolt 9 with locking plate seat 5, and locking plate 4 is located between check dish 2 and the locking plate seat 5.
Coupling link 6 is connected with roller carrier shaft 10 keys.
For overcoming the deficiency of existing carrying roller and brake equipment, in conjunction with the requirement of multiple delivery system operating condition, the utility model is designed a kind of novel Non-return idler, and carrying roller is effectively braked.This device has improved the reliability of conveyer, has prolonged the service life of conveyer, has reduced the operation and maintenance expense of conveyer.The utility model has following innovative point:
The bearing seat of novel Non-return idler and check dish adopt and be welded to connect, and be simple in structure, simplified assembly technology;
The locking plate seat of novel Non-return idler and coupling link adopt the high molecular abrasion-proof material to process, and have prolonged the life-span of novel Non-return idler, have reduced noise of equipment.
Further specify below in conjunction with the principle of work of accompanying drawing novel Non-return idler:
Novel Non-return idler is installed on the upper conveying belt type conveyer support, and when belt conveyer brought into operation, the carrying roller rotative speed was lower, and locking plate 4 suffered centnifugal forces are less than its gravity, and coupling link 6 is stirred locking plate 4; When the rotating speed of carrying roller reached normal speed, bearing pin 3 rotations were attached on the inwall of roller skin 7 locking plate 4 in the centrifugal action lower edge, and this moment, locking plate 4 can not contact with coupling link 6.
When the belt conveyer emergency braking or when being about to reverse; Carrying roller speed under the friction force effect of conveyor belt running drops to zero and the trend of reversing arranged; This moment, the centnifugal force owing to locking plate 4 contacted with coupling link 6 less than its action of gravity whereabouts; Fall between locking plate seat 5 and the coupling link 6 " stuck ", prevent the carrying roller reversing, thereby stoped the load-transfer device reversing.
The beneficial effect of the utility model is:
Rational in infrastructure, installation, easy to adjust, applicability is strong;
Noise is low during operation, and it is little to wear and tear;
Operating efficiency is high, and non-maintaining, operating cost is low.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical personnel of being familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
