Abstract
The utility model relates to a loose pulley assembly for rise to put in a position among wire rope electric block, it includes pulley (1) and pulley endotheca (2), its characterized in that, this pulley (1) has rim portion (11), be provided with in this rim portion (11) with wire rope assorted grooving (111), this loose pulley assembly still includes a plurality of rollers (3), and this roller (3) set up between this pulley (1) and pulley endotheca (2), forms the ball bearing structure. The utility model discloses a loose pulley assembly can reduce the friction between wire rope and the pulley to it to the wearing and tearing with the pulley, avoids causing the pulley to damage, lead to appearing the accident scheduling problem effectively to reduce wire rope.
Description
Technical field
The utility model relates to a kind of for working the pulley assembly of reusing in steel-wire rope type electric block.
Background technology
Steel-wire rope type electric block weight-lifting equipment coordinates the use such as I-beam section, H profile steel or box beam, and gin wheel is then the indispensable cast iron part of steel-wire rope type electric block, for guiding steel wire rope.Common pulley all adopts cast iron, the pulley of cast iron with steel rope rub use a period of time after there is wear damage problem, and usually thought that pulley is consumable accessory.The dangerous meeting of consumable accessory causes occurring accident problem.
Carefully analyze said structure, be not difficult to find that this existing cast iron gin wheel exists following weak point: steel rope, for the wearing and tearing with pulley, causes pulley to damage, and causes occurring accident problem.
Thus, need badly at present and provide a kind of novel for working the pulley assembly of reusing in steel-wire rope type electric block.
Utility model content
Solved technical matters of the present utility model is to provide a kind of for working the pulley assembly of reusing in steel-wire rope type electric block, this pulley assembly can reduce the friction between steel rope and pulley, thus effectively reduce steel rope for the wearing and tearing with pulley, avoid causing pulley to damage, cause occurring the problems such as accident.
For solving the problems of the technologies described above, the utility model provides a kind of for working the pulley assembly of reusing in steel-wire rope type electric block, and it comprises pulley and pulley inner sleeve, and this pulley has drop center portion, this drop center portion is provided with the grooving matched with steel rope; This pulley assembly also comprises some rollers, and this roller is arranged between this pulley and pulley inner sleeve, forms ball bearing structure.
The utility model creatively sets up grooving in the drop center portion of pulley, makes it to mate with steel rope.In pulley assembly working process, due to the setting of roller, define ball bearing structure, reduce the friction between steel rope and pulley, thus limited minimizing steel rope is for the wearing and tearing of pulley.Compared to existing like product, the longer service life of pulley assembly of the present utility model, also can avoid the generation of accident simultaneously.
In addition, owing to having set up grooving, in use, can not there is relative sliding in steel rope and pulley to slide assemblies of the present utility model, and fixing between the two is more firm.
More preferably, this roller arranged outside roller dust protecting cap.
Finally, the utility model middle pulley, pulley inner sleeve and roller are made up of bearing steel.This pulley is fixed pulley and/or fixed pulley.
Pulley of the present utility model, pulley inner sleeve and roller material adopt bearing steel (GCr15) to make, and it has very high intensity, and be not easily worn breaking-up, effectively increases the tenure of use of Whole Equipment.
In sum, pulley assembly of the present utility model, can solve the wearing and tearing of pulley, cause pulley to damage, cause occurring the problems such as accident.Its pulley, the material of pulley inner sleeve and roller all adopts bearing steel (GCr15) to make, and have very high intensity, be not easily worn breaking-up.The drop center portion with grooving extended to form processed by pulley at circumferencial direction, can be used for steel rope in grooving transmission.Pulley assembly of the present utility model can use in fixed pulley and movable pulley, because accessory is assembled into one, for simpler when assembling movable pulley or fixed pulley.

Detailed description of the invention
The utility model provides a kind of for working the pulley assembly of reusing in steel-wire rope type electric block.Refer to Fig. 1 and Fig. 2.This pulley assembly comprises pulley 1 and pulley inner sleeve 2, and wherein, this pulley 1 has drop center portion 11, this drop center portion 11 is provided with the grooving 111 matched with steel rope 5.In addition, this pulley assembly also comprises some rollers 3, and this roller 3 is arranged between this pulley 1 and pulley inner sleeve 2, forms ball bearing structure.This roller 3 arranged outside roller dust protecting cap 4.Significantly can increase pulley thus and pass on efficiency.
By offering the grooving 111 that to match with steel rope 5 in drop center portion 11, steel rope 5 is by card with in this grooving 111, in pulley assembly working process, steel rope 5 rotates in grooving 111, due to the setting of roller 3, define ball bearing structure, reduce the friction between steel rope 5 and pulley 1, thus limited minimizing steel rope 5 is for the wearing and tearing of pulley 1.
Refer to Fig. 3 and Fig. 4, pulley assembly of the present utility model can be used in fixed pulley and/or fixed pulley.Specifically, only need pulley 1 to replace with fixed pulley or movable pulley.Wherein Fig. 3 middle pulley 1 is fixed pulley, and Fig. 4 middle pulley is movable pulley.Accessory of the present utility model is finally assembled into one and fitting process is comparatively simple and direct, equally comparatively simple and direct for the process changing movable pulley or fixed pulley, is easy to operation.
Finally, pulley assembly of the present utility model, can solve the wearing and tearing of pulley, cause pulley to damage, cause occurring the problems such as accident.Its pulley, the material of pulley inner sleeve and roller all adopts bearing steel (GCr15) to make, and have very high intensity, be not easily worn breaking-up.The drop center portion with grooving extended to form processed by pulley at circumferencial direction, can be used for steel rope in grooving transmission.Pulley assembly of the present utility model can use in fixed pulley and movable pulley, because accessory is assembled into one, for simpler when assembling movable pulley or fixed pulley.
