Abstract
The utility model relates to a bearing bush fixing device for a moving head sheave of a rope friction hoist. The bearing bush fixing device for the moving head sheave of the rope friction hoist comprises a head sheave shaft of the moving head sheave of the rope friction hoist, a hub and a bearing bush sleeve formed by connecting four sections of half bearing bushes with flanges in sequence in an end to end mode, the half bearing bushes are fixedly connected with the hub through sunk screws, the bearing bush sleeve is mounted on the head sheave shaft, half key grooves are formed in the two ends of the flange of each half bearing bush, the two half key grooves at a joint position of two adjacent sections of half bearing bushes form a flat key groove, a flat key block is mounted in each flat key groove, and the inner side and the outer side of each flat key block are welded to the hub respectively. The head sheave rotating deflection caused by relative sliding of the half bearing bushes in an inner hole of the hub due to the fact that the screws of the half bearing bushes of the moving head sheave are cut off can be avoided effectively. The service period of a head sheave device is prolonged, and safety of lifting operation is guaranteed.
Description
Technical field
The utility model relates to a kind of bearing shell anchor fitting, belongs to propeller boss and connects field of mechanical technique.The spacing of floating sheave bearing shell that is mainly used in mine console model multi-rope friction hoist's head sheave device fixed.
Background technology
Mine console model multi-rope friction hoist's head sheave device is typically equipped with multiple floating sheaves.In order to solve the wear problem between floating sheave and day wheel shaft, generally can between floating sheave and day wheel shaft, axle bush sleeve be set, axle bush sleeve is connected with floating sheave by countersunk-heat bolt, and it is lubricated to contacting position easy to wear enforcement to increase lubricating system, such as the Chinese utility model that publication number is CN202785204U disclosed " console model multi-rope friction hoist's head sheave device " has just adopted this structure.
Because of reasons such as manufacture, installation, uses, the fastener meeting short-duration failure of the fixing bearing shell of most floating sheaves, fixes the countersunk-heat bolt complete rupture (being cut off) of use.The specification of attempting increasing countersunk-heat bolt in practice still can not address this problem.The fastener of bearing shell can cause bearing shell to rotate and longitudinal travel after losing efficacy, make head sheave rotation beat serious, can not implement normal hoisting operation, and in use, this phenomenon is very general.
Utility model content
Technical problem to be solved in the utility model is that a kind of friction drive hoist floating sheave bearing shell anchor fitting, solves bearing shell solid failure problem, to extend the operating cycles of head sheave apparatus, and ensures to promote the safety of moving.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of friction drive hoist floating sheave bearing shell anchor fitting, comprise sky wheel shaft and the wheel hub of friction drive hoist floating sheave, also comprise four sections of halfliners with flanging axle bush sleeve of end to end composition successively, described halfliner is fixedly connected by flathead screw and wheel hub, described axle bush sleeve is arranged on day wheel shaft, it is characterized in that: two ends of each halfliner flanging offer respectively half keyway, the junction of adjacent two sections of halfliners becomes a flat key groove by two and half key-way shape, flat key piece is installed in flat key groove, and weld mutually with wheel hub respectively the inside and outside both sides of flat key piece.
Weld seam between flat key piece and wheel hub comprises weld joint on inner side and outer side weld; Weld joint on inner side is wide concordant with the inner of flat key piece; Outer side weld covers outer end and the both sides, outer end of flat key piece continuously.
At halfliner flanging, place is processed with into complete keyway, and flat key piece is installed in complete keyway, and weld mutually with wheel hub respectively the inside and outside both sides of flat key piece.
Good effect of the present utility model is: adopt flat key to coordinate flathead screw to implement bearing shell spacing, more than the anti-shearing load of this structure improves twice; In addition, also solve the discontinuity that screw anchor shaft tile structure causes, the problem of loosening (and cannot be fastening) after operation; The utility model can effectively prevent that floating sheave halfliner is cut off because of screw in ground, and halfliner produces at wheelboss inner hole the head sheave that relative sliding causes and rotates beat problem.This device also has simple and reliable, and cost is low, implements the feature that is easy to.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Further illustrate the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises sky wheel shaft 8 and the wheel hub 1 of friction drive hoist floating sheave, also comprise four sections of halfliners 2 with flanging (flange) axle bush sleeve of end to end composition successively, described halfliner 2 is fixedly connected by flathead screw 5 and wheel hub 1, and described axle bush sleeve is arranged on day wheel shaft 8.
Two ends of each halfliner 2 flanging (being flange) offer respectively half keyway, the junction of adjacent two sections of halfliners 2 becomes a flat key groove by two and half key-way shape, flat key piece 3 is installed in flat key groove, and weld mutually with wheel hub 1 respectively the inside and outside both sides of flat key piece 3, weld joint on inner side 7 is wide concordant with the inner of flat key piece 3; Outer side weld 4 covers outer end and the both sides, outer end of flat key piece 3 continuously.
Bearing shell, for being split into halfliner structure, is respectively processed an excision part by two halves bearing shell two ends, is combined to form a keyway, or is processed into complete keyway 6 in the appropriate location of halfliner 2 flangings, and both select a kind of, the use of also can working in coordination.According to the size of keyway, the flat key of configure generic, on the wheel hub of floating sheave, and carries out the protection of suitable key piece slip-off preventing by key block welding.
The processing mounting means that is below axle bush sleeve is given an example.
1), in the time that changing floating sheave halfliner, preparation implements; Unclamp and be pressed in the hoisting cable on head sheave apparatus and be fixed, floating sheave can be rotated and longitudinal travel; Remove floating sheave clamp, move axially floating sheave, make to leave working space between adjacent two head sheaves.
2) halfliner of floating sheave is gone to the bottom of day wheel shaft 8, unclamp flathead screw 5, take out the halfliner 2 of floating sheave wheel hub 1 endoporus, processing half keyway, and halfliner 3 is put into head sheave wheel hub 1 endoporus, second half bearing shell is put in same operation; Then by on-the-spot flat key piece 3 bedding-in, with keyway medial surface be flush fit, inside and outside dual-side and outer face and wheel hub 1 are welded and fixed, weld bead height is greater than 10mm, the opposite side halfliner of this floating sheave completes fixing with the same manner; All the other floating sheaves (3-5) carry out according to this equally.Finally, flat key piece need be prevented to use procedure is because of fixing that welding comes off.
