The main components of the bucket elevator of chain transmission comprise a shell, a conveying chain, a hopper, a driving wheel (head wheel), a bend wheel (tail wheel), a tensioning device, a guide device, a charging opening and a discharging opening.

In the existing standard bucket elevator chain, the conveying of non-polished and polished materials is usually durable, the abrasion degree of each part of the chain is slight, and the service life is long. However, when conveying highly polished materials, the abrasion of the materials on the chain is fatal, and the service life of the chain is seriously influenced. In addition, if the high-temperature residual materials for conveying meet the damp and agglomerate on the inner channel of the bucket elevator, the space through which the chain passes is reduced, the abrasion of the chain is further aggravated, and the service life of the chain is shortened. Accordingly, there is a need to develop elevator chains with improved reliability and durability that can be adapted for transporting highly polished or high temperature materials.

1. the locking device comprises a locking pin 21, an outer wing plate 22, an outer chain plate 3, a threaded pin 41, a first inner chain plate 42, a second inner chain plate 5, a sleeve 6, a nut 7, a roller 8 and a spacer ring.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

It should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are intended to be construed broadly, as if they were connected either fixedly or removably, or as integrally formed structures. To those of ordinary skill in the art, the specific meaning of such terms in this patent may be understood as appropriate.

As shown in fig. 1 and 2, the present invention relates to a screw-type elevator chain, which comprises an outer wing plate 21, a first inner link plate 41, a second inner link plate 42, an outer link plate 22, a nut 6 for limiting, and a screw pin shaft 3 for connecting the outer wing plate 21, the first inner link plate 41, the second inner link plate 42, and the outer link plate 22. The threaded pin shaft 3 comprises a pin shaft column and threaded heads arranged at two end parts of the pin shaft column; the thread head is in thread fit with the nut 6, so that the abrasion resistance of the thread pin shaft 3 and the stability and the convenience in disassembly and assembly of the whole structure of the hoist chain are obviously improved while the outer wing plate 21, the first inner chain plate 41, the second inner chain plate 42 and the outer chain plate 22 are connected, the phenomenon that the chain link of the hoist chain falls off in the using process is effectively avoided, the abrasion resistance, the reliability and the service life of the hoist chain are improved, and the working stability and the production safety of the hoist chain are further improved. The pin shaft column is sleeved with a sleeve 5; the sleeve 5 is provided with a roller 7.

As shown in fig. 2, the outer wing plate 21 is a bent plate. As shown in fig. 1, the outer wing plate 2 is provided with a plurality of mounting holes.

As shown in fig. 1 and 2, a locking pin 1 for preventing the nut 6 from loosening or falling off is connected to the screw head. Preferably, the locking pin 1 is riveted with a threaded head. Therefore, the working stability and the production safety of the hoist chain are improved, and the phenomenon that the nut 6 is loosened or falls off when the hoist chain runs is effectively avoided.

Example 1

The roller 7 is sleeved on the sleeve 5. When the hoist chain is in operation, the roller 7 and the sleeve 5, and the sleeve 5 and the pin shaft can rotate relatively.

Example 2

The roller 7 is fixedly connected with the sleeve 5. When the hoist chain is in operation, only the sleeve 5 and the pin shaft can rotate relatively.

As shown in fig. 2, spacer rings 8 are disposed between the first inner link plate 41 and the rollers 7 and between the second inner link plate 42 and the rollers 7. Preferably, the spacer ring 8 is sleeved on the sleeve 5. The spacer rings 8 can effectively prevent the first and second

inner link plates

41 and 42 from directly contacting and wearing against the rollers 7, thereby improving the service life of the first and second

inner link plates

41 and 42 and the rolling stability of the rollers 7.

The first inner chain plate 41 and the second inner chain plate 42 are provided with assembling holes; the two ends of the sleeve 5 are positioned in the assembling holes; and pin shaft holes matched with the pin shafts are formed in the outer wing plate 21 and the outer chain plate 22. Namely, the first inner link plate 41, the second inner link plate 42, the two sleeves 5 and the two rollers 7 form an inner chain link; the outer wing plate 21 and the outer chain plate 22 penetrate through the two threaded pin shafts 3 to form an outer chain link. The working stability and reliability of the hoist chain are further improved.

The chain structure of the elevator is stable, the elevator is convenient to disassemble and assemble, the abrasion resistance and the reliability are excellent, the working stability and the production safety are good, the service life is long, and the chain structure is suitable for conveying high-abrasion-resistance materials or high-temperature materials.
