Abstract
The utility model discloses a connection structure of a chain pin and a pin shaft on a chain. The connection structure comprises an upper outer chain plate, a lower outer chain plate and a protective sleeve, wherein the upper outer chain plate is connected with the lower outer chain plate by the pin shaft; an inner hole is formed in the center of the protective sleeve; one end of the pin shaft is inserted into the inner hole of the protective sleeve and is in close fit with the inner hole; an annular groove is formed in an outer ring of the protective sleeve; a chain pin hole which leads to the inner hole of the protective sleeve is formed in the annular groove; and the chain pin is inserted into the chain pin hole, and the end of the chain pin is fixed on the pin shaft in the inner hole of the protective sleeve. The connection structure is skillful in improvement; the chain pin is hidden in a chain pin groove, so that the abrasion of the chain pin due to contact with materials is avoided; and the chain plates are protected from dropping, so that the using safety of the conveying chain is ensured.
Description
Technical field
The utility model relates to the conveyer chain of chain-linked conveyer, mainly is the connection structure of chain pin and bearing pin on the chain.
Background technology
The bearing pin of tradition conveyer chain is that flat gesture is processed at two ends (or an end), cooperates by flat gesture hole with pin link plate, and the outside is worn chain pin again and fixed.Its shortcoming is, bearing pin is with after flat gesture hole cooperates, the chain pin of pin link plate outside easily in use is subjected to the wearing and tearing of material Long Term Contact, pin link plate extrusion abrasion etc. former thereby rupture, come off, cause damage parts, and in the undiscovered situation of maintenance repair, easily cause equipment breakdown, have very large potential safety hazard.
The utility model content
Technical problem to be solved in the utility model provides the connection structure of chain pin and bearing pin on a kind of chain; its structural development is ingenious; chain pin is ensconced in the chain cotter way and is difficult for by the material contact wear, and the protection carrier bar does not take off chain, thereby has guaranteed the safety that conveyer chain uses.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The connection structure of chain pin and bearing pin on a kind of chain, include upper and lower pin link plate, connect by bearing pin between the upper and lower pin link plate, it is characterized in that: also include a protecting sleeve, the center of described protecting sleeve has endoporus, and an end of described bearing pin is inserted in the endoporus of protecting sleeve and with it and closely cooperates; Have circular groove on the outer ring of described protecting sleeve, have the chain pin-and-hole that leads to the protecting sleeve endoporus on the circular groove, have chain pin to insert in the chain pin-and-hole and the termination of chain pin is fixed on the bearing pin in the protecting sleeve endoporus.
Structure of the present utility model has solved the defective of original design; the easy wearing and tearing of chain pin that are flat gesture end are broken; make carrier bar take off chain; cause serious consequence, this protecting sleeve and the flat gesture end of bearing pin be tight to be crossed to win and cooperates, and chain pin is unlikely to by the pin link plate improper wearing and tearing that are in operation; protected chain pin; instant chain pin is worn, and protecting sleeve also can play the protection carrier bar and not take off chain, can not cause the serious consequences such as chain rupture.
Use successful especially in the conveyer chain of present technique chain-linked conveyer below power plant's electricity gathers dust; this equipment overhaul cycle long (mounting means causes the maintenance inconvenience); chiseling property of material mill is large, even thereby after using the utility model the period of inspection and repair long, also can protect equipment normally to move.
The utility model has the advantages that:
The utility model structural development is ingenious, and chain pin is ensconced in the chain cotter way and is difficult for by the material contact wear, and the protection carrier bar does not take off chain, thereby has guaranteed the safety that conveyer chain uses.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the constructional drawing of the utility model protecting sleeve.
The specific embodiment
Referring to Fig. 1, the connection structure of chain pin and bearing pin on a kind of chain, include upper and lower pin link plate 1 and 2, connect by bearing pin 3 between the upper and lower pin link plate 1 and 2, also include a protecting sleeve 4, the center of described protecting sleeve 4 has endoporus 5, and an end of described bearing pin 3 is inserted in the endoporus 5 of protecting sleeve and with it and closely cooperates; Have circular groove 6 on the outer ring of described protecting sleeve 4, have the chain pin-and-hole 7 that leads to the protecting sleeve endoporus on the circular groove 6, have chain pin to insert in the chain pin-and-hole 7 and the termination of chain pin is fixed on the bearing pin 3 in protecting sleeve endoporus 5.
