Description

Novel Non-return idler
Technical field
The present invention relates to a kind of novel Non-return idler, be 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.
Summary of the invention
The purpose of this invention is to provide a kind of novel Non-return idler.
The objective of the invention is to realize through following technical scheme:
Novel Non-return idler of the present invention comprises bearing seat, bearing pin, locking plate, torsion spring, locking plate seat, coupling link, socket bolt, roller skin and roller carrier shaft.Bearing seat, locking plate are connected through bearing pin with the locking plate seat, and locking plate is located between bearing seat and the locking plate seat, and bearing seat and locking plate seat are fixed through socket bolt, and locking plate is provided with groove; Torsion spring is located in the groove of locking plate, and coupling link is connected with the carrying roller axle key, and coupling link adopts ratchet structure; Coupling link is provided with 24 external tooths, and locking plate adopts pawl structures, and locking plate is provided with 6; 6 locking plates adopt distribution or asymmetrical distribution, and 62.5 ° at interval of adjacent two locking plates wherein have 47.5 ° at interval of two adjacent locking plates.
Technical scheme by the invention described above can be found out, novel Non-return idler of the present invention is rational in infrastructure; Installation, easy to adjust, applicability is strong, and the check moment of bearing is big; Safe and reliable; Noise is little, and 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.

The specific embodiment
Novel Non-return idler of the present invention; The specific embodiment that it is preferable such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, novel Non-return idler comprise bearing seat 1, bearing pin 2, locking plate 3, torsion spring 4, locking plate seat 5, coupling link 6, socket bolt 7, roller skin 8 and roller carrier shaft 9.
Bearing seat 1, locking plate 3 are connected through bearing pin 2 with locking plate seat 5; Bearing seat 1 is fixing through socket bolt 7 with locking plate seat 5, and locking plate 3 is located between bearing seat 1 and the locking plate seat 5, and locking plate 3 is provided with groove; Torsion spring 4 is located in the groove of locking plate 3, and coupling link 6 is connected with roller carrier shaft 9 keys.
Coupling link 6 adopts ratchet structure, and coupling link 6 is provided with 24 external tooths, and locking plate 3 adopts pawl structures, and locking plate 3 is provided with 6, and 6 locking plates 3 adopt distribution or asymmetrical distribution, and 62.5 ° at interval of adjacent two locking plates 3 wherein have 47.5 ° at interval of two adjacent locking plates 3.
For overcoming the deficiency of existing carrying roller and brake equipment, in conjunction with the requirement of multiple delivery system operating condition, the present invention designs 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 present invention has following inventive point:
The locking plate of novel Non-return idler is provided with groove, is provided with torsion spring in the groove of locking plate, can actv. guarantees the timely optimum check of locking plate;
The coupling link of novel Non-return idler adopts ratchet structure; Coupling link is provided with 24 external tooths, and locking plate adopts pawl structures, and locking plate is provided with 6; 6 locking plates adopt distribution or asymmetrical distribution; 62.5 ° at interval of adjacent two locking plates wherein have 47.5 ° at interval of two adjacent locking plates, can guarantee Non-return idler check within 2.5 ° by actv.;
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 3 suffered centnifugal forces are less than the elastic force of its gravity and torsion spring, and coupling link 6 is stirred locking plate 3; When the rotating speed of carrying roller reaches normal speed, then the centnifugal force that locking plate 3 receives greater than the elastic force locking plate 3 of self gravitation and torsion spring along bearing pin 2 rotations, this moment, locking plate 3 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, 6 locking plates 3 all contacted with coupling link 6 under the application force of torsion spring; And embed in the external tooth of coupling link 6 " stuck ", prevent the carrying roller reversing, thereby stoped the load-transfer device reversing near the front end of the locking plate 3 of coupling link 6.
The invention has the beneficial effects as follows:
Rational in infrastructure, installation, easy to adjust, applicability is strong;
The check moment of bearing is big, safe and reliable, and noise is little;
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.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical personnel of being familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
