Background technology
Belt conveyer is widely used in all trades and professions of national product, for social development plays irreplaceable effect, have be used for transport bulk material, have be used for transport work piece, both can operate continuously, also can match with the technological process in production procedure, form rhythmical Detroit automation lane of traffic, powdery can be transported, granule, little lump material, medium size can also be transported, bulk materials, even can transport the material of granularity more than 600 millimeters, environment for use is generally-20 DEG C to+40 DEG C, also the high temperature resistant type conveyer that can adapt to 500 DEG C is had, it runs at a high speed, steadily, noise is low, and can uphill/downhill transmission, be used in coal, ore, sand, cement, chemical fertilizer, the transport field of the multiple industry such as grain.
China has carried weight department the various element size normalisations of belt conveyer, most representative is the universal belt conveyer of DTII type fixed type, it is described that the various parts of belt conveyer, wherein there is a kind of trough idler, be made up of three carrying rollers or four carrying rollers, wherein there are two side rollers, all the other are middle idler rollers, there is pillar at carrying roller two ends, quarter line pillaring and/or B-C post respectively, hold down groove is had respectively above quarter line pillaring and B-C post, the spindle nose at middle idler roller two ends is stuck in the hold down groove of two B-C posts, the spindle nose at side roller two ends is stuck in the hold down groove of a B-C post and a quarter line pillaring, B-C post and quarter line pillaring are fixedly connected respectively on the angle steel of horizontal positioned, bottom, angle steel two ends is fixed with band steel, angle steel, band steel, B-C post and quarter line pillaring composition crossbeam, four is generally be linked togather by welding.Have fixed orifice above band steel, by this fixed orifice, crossbeam uses together with Bolt Connection with two longerons of belt conveyer middle frame.
At the discharging point place of belt conveyer, material falls to having kinetic energy, larger to the ram ratio of load-transfer device and carrying roller, usual use impact idler substitutes common carrying roller, the roller surfaces of traditional impact idler is made up of elastic caoutchouc or is made by High molecular material, and elastomeric material can shock absorbing.But only roller rest plays buffer action, and elastic range is little, and when running into material particles and being larger, surge time is short, still damages load-transfer device.Long-play, large to the resilient roller wearing and tearing of impact idler, equipment attrition is very serious, and parts replacement is very frequent, and maintenance workload is huge, and this buffering scheme also requires further improvement.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, provides a kind of cushion characteristic better with the flute profile impact idler of disc spring and the combination of longeron.
The utility model is achieved through the following technical solutions:
With the flute profile impact idler of disc spring and a combination for longeron, comprise longeron, impact idler, transverse beam assembly, bearing pin, disc spring and guide rod; Multiple longitudinal hole is had above longeron; Transverse beam assembly comprises horizontal camber beam, quarter line pillaring and B-C post, and horizontal camber beam two ends are high, and middle low, two ends are fixed with quarter line pillaring, and centre is fixed with B-C post, have hold down groove respectively above quarter line pillaring and B-C post, and the spindle nose at impact idler two ends is stuck in hold down groove; Horizontal camber beam two ends also have crossbeam earrings, and there is guide rod earrings guide rod upper end, by bearing pin, and crossbeam earrings and guide rod earrings composition hinge; Guide rod is also fixed with overhead gage, one group of disc spring is through on guide rod, lower end of the guide rod is through in longitudinal hole, and guide rod and longeron constitute moving sets, and guide rod lower end is fixed with lower baffle plate, the flexible power of this group disc spring, upper end compresses overhead gage, and lower end compresses longeron, and longeron compresses lower baffle plate, overhead gage and lower baffle plate are applied to guide rod strength, and guide rod is subject to tensile force.
Load-transfer device is layered on flute profile impact idler, flute profile impact idler bears the gravity of load-transfer device and material above, at discharging point place, when there being large granular materials to fall on load-transfer device, produce very large impulsive force, very large instantaneous pressure is produced to load-transfer device, and guide rod can be passed to by transverse beam assembly rapidly, disc spring and longeron, disc spring is compressed after being under pressure, length shortens, thus play buffer action, guide rod moves down a segment distance along longitudinal hole, material fall steady after instantaneous pressure disappear, disc spring returns to the original length again, guide rod gets back to original position along longitudinal hole again.Had the buffer action of disc spring, the destructive effect of large granular materials to load-transfer device and impact idler reduces, and extends their service life, decreases the number of times and maintenance workload of changing spare part, improves production efficiency.
The manufactured materials of disc spring selects 60Si2MnA or 50CrVA usually, and this kind of material has higher elastic limit, yield limit, impact resistance and enough large plastic deformation performance, is suitable for making disc spring.
The beneficial effects of the utility model: reduce the destructive effect of large granular materials to load-transfer device and impact idler, extend their service life, decrease the number of times and maintenance workload of changing spare part, improve production efficiency.
