Abstract
The utility model discloses a closed type motion pulley, comprising a pulley shaft (10) and a pulley component connected with the pulley shaft (10). The pulley component comprises a motion pulley (8), a rolling bearing (2), a shaft sleeve (6), a shaft sleeve (7), and a blocking ring (3). A hollow blocking plate component is provided on the pulley shaft (10), and the pulley component is provided inside the hollow blocking plate component. The closed type motion pulley adopting the structure can ensure that a steel rope is always arranged inside the pulley slot of the motion pulley in the process of motion no matter what directional acting force is given by ambient, which can efficiently prevent accidents from generating due to the fact that the steel rope is ejected out. End covers can be discharged from the pulley shaft, which is convenient to maintain the pulley component arranged inside the blocking plate component.
Description
Technical field:
The utility model relates to a kind of pulley, specifically is a kind of motion pulley.
Background technique:
Radiation processing technology physics, chemistry or biological variation that mainly to be the γShe Xian that produces with cobalt-60 and cesium-137 radioactive source interact and produce with material or material, to the process that material or material carry out the RADIATION PROCESSING processing, application is very extensive.Cobalt-60 radioactive source is installed in screen frame or the flower pot type source frame usually, is housed in the well, by wire rope the source frame is risen ground by electrical hoist or oil cylinder during use or drops in the well.This lifting process need turn to lifting through the motion pulley of different direction, the ordinary movement pulley all is the motion pulley of open type, once being subjected to beyond thought external force, boom hoist cable does the time spent, wire rope may be upspring in moment, cause wire rope to eject outside the pulley groove, cause wire rope to be clamped, and can not move, cause the generation of machinery or radioactive accident at pulley outer edge place.
Summary of the invention:
At the technical problem that exists in the prior art, the utility model provides a kind of wire rope that can guarantee to be in the enclosed motion pulley in the motion pulley groove all the time.
The utility model is for reaching above purpose, be to realize: a kind of closed motion pulley is provided by such technological scheme, comprise pulley spindle and coupled pulley assembly, pulley assembly comprises motion pulley, rolling bearing, 2 axle sleeves, back-up ring, the baffle plate assembly of hollow is set on pulley spindle, described pulley assembly is placed the inside of baffle plate assembly.
Baffle plate assembly comprises right baffle-plate, right baffle plate, and the right baffle-plate, pulley assembly, the right baffle plate that are successively set on the pulley spindle link together; The upper end of right baffle-plate, right baffle plate links to each other with pressing plate respectively, and the lower end links to each other with base respectively.
Right its centre is provided with through hole, and the diameter of this through hole is greater than the diameter of motion pulley, is arranged on end cap on the pulley spindle and passes this through hole and link to each other with pulley assembly.
Adopt the closed motion pulley of this structure, because pulley is closed in the baffle plate assembly, therefore wire rope extraneous active force that gives any direction no matter in movement process, all be positioned at the pulley groove of motion pulley all the time, wire rope can not take place eject the outer situation of motion pulley groove, prevented that effectively ejection owing to wire rope from causing the generation of accident.End cap can unload from pulley spindle, conveniently the pulley assembly that is positioned at baffle plate assembly is keeped in repair.
Description of drawings:
Fig. 1 is the structural representation of closed motion pulley of the present utility model.
Embodiment:
With reference to above-mentioned accompanying drawing, embodiment of the present utility model is elaborated.Fig. 1 has provided a kind of closed motion pulley, comprises pulley spindle 10 and coupled pulley assembly, and pulley assembly comprises motion pulley 8, rolling bearing 2, axle sleeve 6, axle sleeve 7, back-up ring 3.On pulley spindle 10, set gradually right baffle-plate 9, pulley assembly, right baffle plate 11 successively.Right baffle-plate 9 digs concentric a counterbore and a through hole at center position, and the slightly larger in diameter of through hole is in the diameter of pulley spindle 10, and right baffle-plate 9 is enclosed within on the pulley spindle 10 by this through hole; The diameter of this counterbore is bigger 1 millimeter than the external diameter of motion pulley 8, makes the part of motion pulley 8 can be positioned at this counterbore.Right baffle plate 11 is annulus, and the internal diameter of this annulus equals the diameter of right baffle-plate 9 counterbores.The end cap 1 of a circle also is set on pulley spindle 10, and the center of end cap 1 is provided with through hole, and the slightly larger in diameter of this through hole is in the diameter of pulley spindle 10, and end cap 1 is enclosed within on the pulley spindle 10 by this through hole; The diameter of end cap 1 can equal or be slightly less than the internal radius of right baffle plate 11, and like this, end cap 1 can penetrate right baffle plate 11 and contact with pulley assembly.Under the effect of the nut 4 that plays the role of fastening, packing ring 5, right baffle-plate 9, pulley assembly, end cap 1 are joined together.The lower end of right baffle-plate 9 and right baffle plate 11 is welded on the base 12.Pressing plate 13 links to each other with the upper end of right baffle-plate 9 with right baffle plate 11 respectively by screw.The manufactured materials of this closed pulley all selects for use stainless steel 1Cr18Ni9Ti to make.
During real work, closed motion pulley of the present utility model is fixed on desired location by base 12, penetrates the wire rope that lifting uses and get final product.During maintenance, though right baffle-plate 9 and right baffle plate 11 are welded on the base 12, end cap 1 can be removed from pulley spindle 10, so just can keep in repair the pulley assembly that is positioned at baffle plate assembly easily.
