Abstract
The utility model belongs to the thermal material transportation equipment in the metallurgical industry, aiming at the old chain belt structure (see Figure 3) which is characterized in that the chain board is rotated on a fixed trolley that is not airtight and is easy to be blocked by dust; the tread is greater than the chain pitch; the chain is easy to drop; the old chain belt structure is of large friction specific pressure, fast abrasion, and large maintenance workload. The trolley 6 provided by the utility model is externally hanging on the external side of a chain plate (see Figure 3), which is double-deck sealed and makes pure rolling on the track; a pair of trolleys are arranged every other a chain section to alleviate the deadweight, which are easy to maintain. The chain plates are all flat holes, free from abrasion. Though a long axle 5 and a short axle 3 have friction with the axle sleeve, but the specific pressure is lowered and the service life is prolonged. The utility model adopts an arc hopper, which is easy for unloading.
Description
Present most of producer adopts rolling-wheel fixed hot material conveyer chain belt.Chain belt is made up of chain link, square hopper.Chain link is made up of roller, carrier bar, side's cover or circle cover, axle.(as Fig. 1,2) forms hinge by carrier bar double end, side cover and carrier bar single head, circle cover and turns round square hopper and be fixed on above the chain belt carrier bar.Two row's numbers ten onesize rollers are uniform and be fixed on and do dead axle on the frame and rotate, and are bearing in below the carrier bar of the chain belt left and right sides, bear the gravity of chain belt and heat material.So the chain belt hinge is promptly born the bearing force that propulsive effort that chain belt vertically moves is born material again, service conditions is comparatively abominable.
Support the roller of chain belt and material, under the environmental conditions that nothing seals, dust is big, dust enters on the roller axis of revolution very soon, stuck roller, roller and carrier bar transfer cliding friction to by friction of rolling, and friction force is multiplied, once the roller that is stuck increases, cause falling phenomenon appearance such as chain.
When roller width between centers during greater than pitch, under material and chain belt action of gravity, the hinge of chain belt is done upper and lower crank motion again when vertically moving.So this moment, hinge had low-angle relatively rotating, this just makes wear of hinge, makes the matter worse, and the chain belt maintenance capacity is big, and the life-span is short.3 months change partes of complete machine operation, 8 wheat harvesting period chain belts are scrapped.
The purpose of this utility model provides a kind of roller and is difficult for stuckly, and chain belt is when vertical operation, and hinge does not have and relatively rotates, and the part of chain belt is wear-resisting, and is not fragile.
The purpose of this utility model is achieved in that adopting the shifting roller cantilever structure is that roller is with the chain Tape movement.Chain belt is provided with a major axis every a chain link, and wear-resisting roller is installed at the major axis two ends, is suspended from the chain link outside, and is supported on the track.Chain belt drives roller and makes pure rolling in orbit, plays deadweight of supporting chain belt and material action of gravity.The roller revolution is paid and is selected antifriction-bearing box for use, and double-layer seal, and dust is difficult to enter, and has guaranteed that chain belt operates steadily under relatively little propulsive effort effect reliably.Hinge relatively rotates phenomenon when having eliminated the vertical operation of chain belt.For guaranteeing that sealing place has excellent abrasive resistance, the fixing wear-resistant sleeve that is easy to dismantle is set between major axis and antifriction-bearing box.Be raising chain tape lifetime, inner plate and sleeve, pin link plate adopts flat hole to cooperate with long and short between centers; Roller, sleeve and long and short axle adopt big gap, and high precision cooperates, and heat treatment, promptly guarantee to move and pay alerting ability, and resistance to abrasion is preferably arranged again, have improved service life.Chain belt did not have zero change part within 1.5 years.
Hopper adopts arcuate structure, is not stained with material in defeated heat delivering material, not material stock.
Below in conjunction with accompanying drawing the utility model structure is further specified:
Fig. 3 is the local semisectional view of chain belt, minor axis 3, major axis 5 respectively with pin link plate 1 flat hole flush fit; Sleeve 4 and inner plate 2 flat hole flush fits; Roller 8 and sleeve 4, sleeve 4 adopts big gap high precision to cooperate with long and short axle 3,5, its revolution is paid rotate flexibly.Roller 8 meshes with high the paying of driving chain rivet, connects to roll to be with sliding reducing friction.
Fig. 6 is the shifting roller semisectional view, and the higher roller housing 11 of hardness adopts free-running fit with major axis 5, and purpose is easy to loading and unloading.Flat hole upper gasket 9 blocks roller housing 8 can not relatively rotate it on major axis 5.Jam nut 13, spring cotter 14 is fixed on stop washer 9 on the major axis 5.
The roller outer face seals with blind lid and bolted, inner end seal ring 10 double-layer seals.Roller 6 adopts middle and high carbon to close the knot steel, and higher hardness is after heat treatment promptly arranged, and dynamic ductility is preferably arranged again.
