Abstract
The utility model relates to a steel wire rope falling-prevention device of a fixed pulley, and belongs to a steel wire rope falling-prevention device of a fixed pulley used under a coal shaft. The steel wire rope falling-prevention device of the fixed pulley mainly resolves the technical problems that an existing steel wire rope falling-prevention device is short in service life of a steel wire rope and complex in structure. According to the technical scheme, the steel wire rope falling-prevention device of the fixed pulley comprises a shaft, a fixed pulley bearing and the fixed pulley, and further comprises a fixed rope blocking plate, a movable rope blocking plate, a movable rope blocking plate bearing and a blocking ring, wherein the fixed rope blocking plate is installed at one side of the fixed pulley through a bolt and arranged on the shaft along with the fixed pulley, the movable rope blocking plate is installed on the movable rope blocking plate bearing, the movable rope blocking plate bearing is installed at one end of the shaft and fixed to the shaft through a bolt, and the blocking ring is installed between the fixed pulley bearing and the movable rope blocking plate bearing. The steel wire rope falling-prevention device of the fixed pulley has the advantages that the steel wire rope is long in service life, the structure is simple and repairing is convenient.
Description
Technical field
The utility model relates to a kind of static pulley protection device about rope jumping, and it belongs to the device that the anti-wire rope of a kind of underground mine use static pulley comes off.
Background technique
At present, most anti-loosening device for wire rope pulley is all made up of pulley bracket, pulley, anti-decylization and positioning plate, although this anti-drop device can prevent wire rope and come off in pulley groove, but owing to preventing that the anti-decylization that wire rope comes off is fixedly connected with pulley bracket with positioning plate, while contact with positioning plate with fixing anti-decylization in the time that wire rope rotates, or can wear and tear wire rope, reduce the working life of wire rope, therefore, the short and baroque defect of the service life of steel wire rope of its existence.
Summary of the invention
The purpose of this utility model is to solve the short and baroque technical problem of service life of steel wire rope that existing anti-loosening device for wire rope pulley exists, provides a kind of service life of steel wire rope static pulley protection device about rope jumping long, simple in structure and easy to maintenance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Static pulley protection device about rope jumping, comprise axle, static pulley bearing and static pulley, wherein: it also comprises determines rope blocking plate, moving rope blocking plate, moving rope blocking plate bearing and back-up ring, determining rope blocking plate is contained in a side of static pulley and is located on axle with static pulley by bolt, moving rope blocking plate is contained on moving rope blocking plate bearing, moving rope blocking plate bearing is contained in one end of axle and is bolted on axle, and back-up ring is contained between static pulley bearing and moving rope blocking plate bearing.
Because the utility model has adopted technique scheme, be provided with one in a side of static pulley and can follow the moving rope blocking plate that wire rope rotates together, wear prevention wire rope, has solved the short and baroque technical problem of service life of steel wire rope that existing anti-loosening device for wire rope pulley exists.Therefore,, compared with background technique, the utlity model has long, the simple in structure and easy to maintenance advantage of service life of steel wire rope.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Embodiment
As shown in drawings, static pulley protection device about rope jumping in the present embodiment, comprise axle 1, static pulley bearing 2 and static pulley 4, wherein: it also comprises determines rope blocking plate 3, moving rope blocking plate 5, moving rope blocking plate bearing 6 and back-up ring 8, determining rope blocking plate 3 is contained in a side of static pulley 4 by bolt and is located on axle 1 with static pulley 4, moving rope blocking plate 5 is contained on moving rope blocking plate bearing 6, moving rope blocking plate bearing 6 is contained in one end of axle 1 and is fixed on axle 1 by bolt 7, and back-up ring 8 is contained between static pulley bearing 2 and moving rope blocking plate bearing 6.Static pulley 4 is contained on axle 1 through static pulley bearing 2.
