Self-lubricating structure of double-row heavy-load cement conveying chain

Abstract

The invention relates to the technical field of self-lubricating conveying chains, and provides a self-lubricating structure of a double-row heavy-load cement conveying chain. The self-lubricating structure effectively improves the lubrication sufficiency of the conveying chain, enhances the high temperature resistance, wear resistance, impact fatigue resistance and the like of the chain, and prolongs the service life of the chain. The self-lubricating structure comprises two closed structures defined by a plurality of chain links, and the two closed structures are arranged in parallel. The self-lubricating structure is characterized in that each chain link comprises an inner chain plate, an outer chain plate and a pin shaft, wherein the outer chain plates and the inner chain plates are oppositely and alternately connected through the pin shafts, a roller is arranged between every two inner chain plates, a sleeve is inserted in the middle of each roller, each sleeve is arranged on thecorresponding pin shaft in a sleeving mode, the pin shafts are in large clearance fit with the sleeves, the inner end of each pin shaft is provided with an end step, the other end of each pin shaft isprovided with an oil groove, and an oil cup is installed at a port of each oil groove in a threaded manner. The self-lubricating structure is particularly suitable for self-lubricating of the heavy-load conveying chain, and has high social use value and application prospects.

Description

technical field [0001] The invention relates to the technical field of self-lubricating conveyor chains, in particular to a self-lubricating structure of a double-row heavy-duty cement conveyor chain. Background technique [0002] The heavy-duty cement conveyor chain is mainly used for various conveying equipment in cement plants. It is mainly used in limestone reclaimers, coal and concrete conveyors, bucket elevators, clinker conveyors and other equipment. The chain is the transmission of these conveying equipment Parts, transmitting motion and power, conveying limestone, coal slag, stone clinker and other materials, the working conditions are very harsh, the load is relatively large, and the wear is relatively severe, which requires the chain to be resistant to high temperature, wear and fatigue. . [0003] The two chains are connected in series by lengthening the pin shaft to form a set of double-row chains. When the chains are running on the machine, they must run synch...

Problems solved by technology

In the process of transporting materials in the conveyor chain, a large amount of dust and corrosive substances often enter the gap of the chain, which will cause the chain link to jam after a long time, greatly affecting the service life of the chain

[0004] The patent with the publication number CN204713971U discloses a conveyor chain with self-lubricating function, which is composed of several groups of series connection units, and each series connection unit includes inner chain plates, outer chain plates, pin shafts and rollers, inner chain plates and outer chain plates. The chain plates are connected by pin shafts, the outer ring of the pin shaft is provided with a wear-resistant layer, and the outer ring of the wear-resistant layer is provided with a roller, and the roller is provided with an oil filling port; The upper end of the support plate is provided with a support platform extending along the side direction of the chain, the support platform is provided with a through hole, the upper end of the support platform is provided with a support frame, and the support frame is provided with rollers. The end of the outer chain plate is provided with an outwardly bent flange, which increases the self-lubricating performance of the chain, but this device is not suitable for the lubrication of heavy-duty cement conveyor chains for a large amount of dust and corrosive substances
