Abstract
The invention discloses a novel non-return carrier roller comprising a bearing block, a pin shaft, six locking plates, torsion springs, a locking plate base, a connecting ring, an inner hexagonal bolt, a roller leather and a carrier roller shaft. The bearing block, the locking plates and the locking plate base are connected by a pin shaft, the locking plates are arranged between the bearing block and the locking plate base, the bearing block and the locking plate base are fixed by the inner hexagonal bolt, grooves are arranged on the locking plates, the torsion springs are arranged in the grooves of the locking plates, the connecting ring is in key connection with the carrier roller shaft and adopts a ratchet wheel structure, the connecting ring is provided with 24 outer teeth, the locking plates adopt pawl structures, the six locking plates are in asymmetrical distribution, the two adjacent locking plates are separated from each other by 62.5 degrees, one of the two adjacent locking plates are separated form each other by 47.5 degrees. The novel non-return carrier roller is rational in structure, convenient in installation and adjustment, strong in adaptability, safe and reliable, and low in noise, bears large non-return force, and can effectively prevent a belt conveyer from sliding downwards and rotating reversely caused by power failure or the breakage of an adhesive tape, and a conveyer with the novel non-return carrier roller runs more safely and reliably.
Description
Technical field
The present invention relates to a kind of Non-return idler, be mainly used in belt conveyer.
Background technology
Belt conveyer is mainly by carrying roller, support, and the compositions such as transfer drive, carrying roller is one of main composition part of belt conveyer, is most widely used.Due to the difference of belt speed and freight volume, the oad of carrying roller is different.Conventional carrying roller kind has: impact idler, parallel roll, aligning carrier roller etc.
At present, carrier roller of belt conveyer mainly contains following kind both at home and abroad
1. parallel roll
For return leg support belt
2. impact idler:
Be arranged on material feeding section below, reduce the suffered impact of load-transfer device
3. aligning carrier roller:
Be used for adjusting belt deflection
But above-mentioned all kinds of carrying rollers itself are all without braking function, conveyer also needs to add special brake equipment in addition and carries out the braking of equipment, and this will cause braking force to be concentrated, and cannot realize the stably stop of belt conveyer, reduce the safety of equipment.
Summary of the invention
The object of this invention is to provide a kind of Non-return idler.
The object of the invention is to be achieved through the following technical solutions:
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 by bearing pin with locking plate seat, and locking plate is located between bearing seat and locking plate seat, and bearing seat and locking plate seat are fixed by socket bolt, locking plate is provided with groove, torsion spring is located in the groove of locking plate, and coupling link is connected with carrying roller axle key, and coupling link adopts ratchet structure, coupling link is provided with 24 external tooths, locking plate adopts pawl structures, and locking plate is provided with 6, and 6 locking plates adopt distribution or asymmetrical distribution,, wherein there are 47.5 °, two adjacent locking plate intervals at 62.5 °, adjacent two locking plate intervals.
Technical scheme by the invention described above can be found out, Non-return idler of the present invention, rational in infrastructure, installation, easy to adjust, applicability is strong, and the check moment of bearing is large, safe and reliable, noise is little, and downslide and reversing in the time of can effectively preventing belt conveyer because of power-off or adhesive tape breaking make conveyer operation more safe and reliable.

Fig. 2 is bearing seat, locking plate and locking plate seat assembling schematic diagram;
Fig. 3 is the left TV structure schematic diagram of locking plate;
Fig. 4 is locking plate distribution or asymmetrical distribution schematic diagram;

Fig. 7 is Non-return idler non-return state schematic diagram.
The specific embodiment
Non-return idler of the present invention, its preferably the specific embodiment as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Non-return idler comprises 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.
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 Non-return idler, and carrying roller is carried out to effective brake.This device has improved the reliability of conveyer, has extended 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 Non-return idler is provided with groove, in the groove of locking plate, is provided with torsion spring, can actv. guarantees the timely optimum check of locking plate;
The coupling link of Non-return idler adopts ratchet structure, coupling link is provided with 24 external tooths, locking plate adopts pawl structures, locking plate is provided with 6,6 locking plates adopt distribution or asymmetrical distribution,, wherein there are 47.5 °, two adjacent locking plate intervals at 62.5 °, adjacent two locking plate intervals, can guarantee Non-return idler check within 2.5 ° by actv.;
The locking plate seat of Non-return idler and coupling link adopt high molecular abrasion-proof material to make, and have extended the life-span of Non-return idler, have reduced noise of equipment.
Below in conjunction with accompanying drawing, the principle of work of Non-return idler is further illustrated:
Non-return idler is arranged on upper conveying belt type conveyer support, and when belt conveyer brings into operation, carrying roller rotative speed is lower, and the suffered centnifugal force of locking plate 3 is 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, so the centnifugal force that locking plate 3 is subject to is greater than the elastic force locking plate 3 of self gravitation and torsion spring along bearing pin 2 rotations, now locking plate 3 can not contact with coupling link 6.
When belt conveyer emergency braking or while being about to reverse, carrying roller speed under the friction force effect of conveyor belt running drops to zero and have the trend of reversing, now 6 locking plates 3 all contact with coupling link 6 under the application force of torsion spring, and the front end that approaches the locking plate 3 of coupling link 6 most embeds the external tooth interior " stuck " of coupling link 6, prevent carrying roller reversing, thereby stoped load-transfer device reversing.
The invention has the beneficial effects as follows:
Rational in infrastructure, installation, easy to adjust, applicability is strong;
The check moment of bearing is large, safe and reliable, and noise is little;
Downslide and reversing in the time of can effectively preventing belt conveyer because of power-off or adhesive tape breaking, make conveyer operation more safe and reliable.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.
