Abstract
The utility model discloses a central-chain bucket elevator chain which is wear resistant and convenient for processing, comprising an outer chain plate (2), an inner chain plate (8), wherein the outer chain plate (2) and the inner chain plate (8) are connected by a hinge pin (6) covered with a sleeve (4) and two ends of the hinge pin (6) are equipped with a shaft end bushing (5). The central-chain bucket elevator chain is characterized in that the outer chain plate (2) and the inner chain plate (8) are respectively equipped with a positioning boss (1) for positioning of the inner chain plate (8) and the outer chain plate (2); and a labyrinth dust-proof structure (10) is positioned at the connections of the outer chain plate (2), inner chain plate (8), sleeve (8) and shaft end bushing (5). The central-chain bucket elevator chain has a simple structure, wherein the labyrinth dust-proof structure can prevent large-particle slag from falling into gaps between the sleeve and the hinge pin and prevent abrasive wear generated due to the slag; a split type structure is used in the positioning boss and the chain plate, is convenient for machine work, and reduces processing cost.
Description
Technical field
The utility model relates to a kind of bucket lifting machine equipment, specifically a kind of central chain bucket elevator chain.
Background technology
In the central chain bucket elevator, chain is one of most important parts, and it plays and material is promoted to the effect in high-altitude by floor level.During use, in cement industry application, due to without dustproof design, slag easily falls between sleeve and bearing pin, causes wearing and tearing; And positioning boss and carrier bar on carrier bar are integrated, the groove that mills out has wedge angle, during carrier bar heat treatment, easy stress is concentrated, easily fracture in the chain operational process, do not have the positioning action to carrier bar, simultaneously, easily cause the wearing and tearing between carrier bar and carrier bar, even retardance operation, damage operational outfit.
Summary of the invention
The purpose of this utility model is to provide a kind of central chain bucket elevator chain wear-resisting, easy to process.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of central chain bucket elevator chain, it comprises pin link plate, inner plate, pin link plate, inner plate connect by the sleeved bearing pin of cover, the two ends of bearing pin are provided with the axle head cover, are respectively equipped with the positioning boss to inner plate, pin link plate location on pin link plate, inner plate; Junction between pin link plate, inner plate, sleeve, axle head cover is the labyrinth type dustproof construction.
Positioning boss described in the utility model comprises back-up ring, spacer, by screw, back-up ring, spacer is fixed on pin link plate or inner plate.
Owing to adopting technique scheme, the utility model has been realized goal of the invention preferably, and it is simple in structure, and the labyrinth type dustproof construction stops the bulky grain slag to fall into sleeve and bearing pin gap, prevents the abrasive wear that slag causes; And positioning boss and carrier bar adopt split-type structural, are convenient to machinework, cut down finished cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A place enlarged diagram of Fig. 1;
Fig. 3 is the B place enlarged diagram of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of central chain bucket elevator chain, it comprises pin link plate 2, inner plate 8, pin link plate 2, inner plate 8 have the bearing pin 6 of sleeve 4 to connect by cover, the two ends of bearing pin 6 are provided with axle head cover 5, are respectively equipped with the positioning boss 1 to inner plate 8, pin link plate 2 location on pin link plate 2, inner plate 8; Junction between pin link plate 2, inner plate 8, sleeve 4, axle head cover 5 is labyrinth type dustproof construction 10.
Positioning boss 1 described in the utility model comprises back-up ring 3, spacer 9, by screw 7, back-up ring 3, spacer 9 is fixed on pin link plate 2 or inner plate 8.
As shown in Figure 2, positioning boss 1 of the present utility model adopts split-type structural with carrier bar, by screw 7, back-up ring 3, spacer 9 are fixed on pin link plate 2 or inner plate 8 and form the positioning boss 1 of pin link plate 2 or inner plate 8, occurred while both having prevented positioning boss 1 heat treatment that stress is concentrated, be convenient to again machinework, cut down finished cost.
As shown in Figure 3, it is 5 ㎜ that the utility model stretches into inner plate 8(the present embodiment with axle head cover 5), inner plate 8 is provided with step, make the junction between pin link plate 2, inner plate 8, sleeve 4, axle head cover 5 form labyrinth type dustproof construction 10, can stop the bulky grain slag to fall into gap between sleeve 4 and bearing pin 6, prevent the abrasive wear that slag causes.
Through real-world operation, between chain hinge pin 6 and sleeve 4, wearing and tearing obviously reduce, and positioning boss 1 non-cracking phenomenon occurs.
Claims (2)
