Abstract
The utility model is related to a kind of furnace lid lifting chain connectors, coordinate with axis pin, the chain joint is integrally formed part, and upper part is to offer the overall structure of perforation pin hole, lower end is spaced several chain pieces, and several chain pieces also offer coaxial pin hole.It is more than the thickness of intermediate chain piece in several chain pieces positioned at the thickness of two side chain pieces.By the way that the form of monolithic chain to be changed to the connection structure of monoblock type, two side chain pieces are thickeied, the cooperation of chain whole group efficiently reduces chain arcing number, improves the tensile strength of chain, reduces the rate of breakdown of arcing fracture.
Description
Technical field
The utility model is related to a kind of chain connection structures.
Background technology
Currently, furnace lid lifting device is mainly promoted using common drive chain, the chain piece and axis pin of chain
Between have there are gap, three ac arc furnaces transmission process chain be easy arcing, under the action of electric current chain piece redden or
Directly by arc-melting, tensile strength is lower, and bell chain breakage causes production accident in lifting process, by being filled to being promoted
The structure set optimizes, and effectively inhibits the generation of arcing fracture accident, and stable operation is that those skilled in the art is needed to solve
Problem certainly.
Fig. 1 is the type of attachment of original furnace cover lifting chain hanging feet, and chain is connect by chain piece with hanging feet, existed between chain piece
Gap, when being grounded abnormal on bell, arcing can occur for furnace cover lifting chain-loose position, and positive benefit at lifting chain hanging feet
In the position, arcing frequent occurrence.Chain piece be either melted under arcing or high temperature under anneal, tensile strength is bright
It is aobvious to decline, bell weight can not be born, chain breakage occurs.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of improved hoisting mechanism for the above-mentioned prior art,
Mainly by being improved to arcing chain joint, it is ensured that bonding strength.
The technical scheme in the invention for solving the above technical problem is：A kind of furnace lid lifting chain connector, with
Axis pin coordinates, and the chain joint is integrally formed part, and upper part is to offer the overall structure of perforation pin hole, and lower end is interval
Several chain pieces of arrangement, several chain pieces also offer coaxial pin hole.
Preferably, it is more than the thickness of intermediate chain piece in several chain pieces positioned at the thickness of two side chain pieces.
Preferably, the thickness in several chain pieces positioned at two side chain pieces is at least 10mm.
Preferably, the gap width of several chain pieces is 5mm.
Compared with prior art, the utility model has the advantage of：By the way that the form of monolithic chain is changed to monoblock type
Connection structure thickeies outer chains piece radian to 10mm, the cooperation of chain whole group, effective to reduce chain arcing number, outer chains
Piece thickeies the tensile strength for improving chain, and external arcing is easy to be found, and by above-mentioned measure, effective control carries
Chain is risen due to being broken caused by arcing.
Description of the drawings
Fig. 1 is the fit structure of existing chain joint and axis pin；
Fig. 2 is the structural schematic diagram of chain joint in the embodiment of the present application；
Fig. 3 is the longitudinal sectional view of structure shown in Fig. 2.
Specific implementation mode
The utility model is described in further detail with reference to embodiments.
A kind of furnace lid lifting chain connector 1 in the present embodiment, coordinates with axis pin, which is integrated into
Type part, upper part are to offer the overall structure 101 of perforation pin hole, and lower end is spaced several chain pieces 102, several chain pieces
102 also offer coaxial pin hole respectively.
It is more than the thickness of intermediate chain piece in several chain pieces positioned at the thickness of two side chain pieces.The thickness of two side chain pieces is 10mm.
The gap width of chain piece is 5mm.
The chain joint of above structure can reduce connector and the virtual connection of axis pin is touched, and reduce chain arcing number, two side chains
Piece thickeies the tensile strength for helping to improve chain.
In addition to the implementation, the utility model further includes having other embodiment, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection domain of the utility model claims.
