Abstract
The invention discloses an assembly type crane pulley device. According to a current integrated pulley, the whole pulley needs to be replaced even only a U-shaped groove is worn, so that great waste is caused. The assembly type crane pulley device comprises a wheel flange and a wheel hub, wherein the outer edge of the wheel flange is provided with a U-shaped groove which is matched with a steel wire rope, the inner side plane of the wheel flange is provided with a concave platform inner hole, a plurality of through holes are formed inside a concave table board, the outer side plane of the wheel hub is provided with a boss outer edge, a plurality of through holes are formed inside a convex table board, the middle of the wheel hub is provided with a bearing hole which is matched with a sliding bearing, and the assembly manner of the wheel flange and the wheel hub is that after the concave table board and the convex table board are matched, bolts penetrate through the through holes in the concave table board and the through holes in the convex table board respectively, and nuts and the bolts are screwed up, so that the wheel flange and the wheel hub are tightly connected into a whole. The assembly type crane pulley device is simple in structure and easy to assemble. By adopting the assembly type crane pulley, the whole pulley needs not to be replaced after the U-shaped groove is worn, and only the wheel flange is replaced, so that the maintenance cost of a crane for production operation can be lowered, and relatively good economic benefit is obtained.
Description
Technical field
The present invention relates to a kind of pulley structure, relate to a kind of build-up type whip-gin structure.
Background technology
At present, all kinds of pulley structures of hoisting crane are generally integral structure.Steel rope is Frictional Slipping in the U-lag of pulley outer rim.Because steel rope Frictional Slipping is frequent, the U-lag of pulley outer rim is easy to wearing and tearing.U-lag wearing and tearing can change the matching relationship of steel rope and U-lag, make steel rope accelerated wear test and lose efficacy, and bring potential safety hazard.Therefore, U-lag may wear to a certain amount of after, just must change pulley.Pulley also becomes one of consumable accessory of hoisting crane, needs periodic inspection and replacing.But to current Integral-structure type pulley, only because of U-lag wearing and tearing, just need to change whole pulley, cause very large waste.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of build-up type whip-gin structure is provided.
A kind of build-up type whip-gin structure of the present invention comprises wheel rim and wheel hub, and the outer rim of described wheel rim is U-lag, coordinates with steel rope; Described wheel rim inner side plane is provided with concave station endoporus, and is provided with some through holes in concave station face; The outer side plane of described wheel hub is provided with boss outer rim, and in boss face, is provided with some through holes; In the middle of described wheel hub, be provided with bearing hole, coordinate with plain bearing; After being coordinated by concave, convex table top when described wheel rim assembles with wheel hub, the some through holes with bolt through concave, convex table top, by nut and bolt tightening, become one wheel rim and wheel hub close-coupled.
Assembled pulley structure of the present invention, simple in structure, be easy to assembling.This assembled pulley structure without changing whole pulley, and only need be changed wheel rim after U-lag wearing and tearing, can reduce the maintenance cost of hoisting crane production operation, brings good economic benefit.Assembled pulley structure of the present invention, coordinates because wheel rim and wheel hub have adopted boss plane, has increased the area of contact between wheel hub and wheel rim, safe and reliable.
Brief description of the drawings
Fig. 1 is assembled pulley structural entity schematic diagram of the present invention.
Fig. 2 is build-up type whip-gin rim construction schematic diagram of the present invention.
Fig. 3 is build-up type whip-gin wheel hub structure schematic diagram of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.
Fig. 1, Fig. 2 and Fig. 3 show build-up type whip-gin structural representation provided by the invention, for convenience of explanation, have only provided part related to the present invention in figure.
As shown in Figure 1, build-up type whip-gin structure provided by the invention is provided with wheel rim 1 and wheel hub 2.As shown in Figure 2, the outer rim of described wheel rim 1 is U-lag 1-1, coordinates with steel rope; Described wheel rim inner side plane is provided with concave station endoporus 1-2, and in concave station face, is provided with 6 through hole 1-3; As shown in Figure 3, the described outer side plane of wheel hub 2 is provided with boss outer rim 2-1, and in boss face, is provided with 6 through hole 2-2; In the middle of described wheel hub 2, be provided with bearing hole 2-3, coordinate with plain bearing.As shown in Figure 1, after being coordinated by concave, convex table top when described wheel rim 1 assembles with wheel hub 2,, tightened respectively by 6 nuts 4 and bolt 3 through 6 through holes of concave, convex platform separately with 6 bolts 3, wheel rim and wheel hub close-coupled are become one.
Wheel rim provided by the invention and wheel hub assembled pulley structure, the U-lag coordinating with steel rope when wheel rim outer rim may wear to and a certain amount ofly has influence on hoisting crane efficiency and when safe, only wheel rim need be changed, and wheel hub still can continue safe handling.In crane job is safeguarded, there is good economic benefit.
In wheel rim provided by the invention and wheel hub assembled pulley structure, wheel rim and wheel hub have adopted concave, convex table top fit structure form, have reduced the accuracy requirement that wheel rim coordinates with wheel hub, have expanded cooperation area of contact, are conducive to transmission of power.
For pulley structure, pulley outer rim main performance requirements is wear-resisting, and inner edge main performance requirements is high strength, and one-piece construction is difficult to take into account for these two performance requriementss.Wheel rim provided by the invention and wheel hub assembled pulley structure, can adopt different materials from inner side wheel hub to outer rim, and to meet, pulley is outer, the difference of inner edge performance requriements.
Wheel rim provided by the invention and wheel hub assembled pulley structure, be applicable to all kinds of pulley mechanisms such as hoisting crane fixed pulley, movable pulley, assembly pulley and leading sheave.
Claims (1)
1. build-up type whip-gin structure, comprises wheel rim and wheel hub, it is characterized in that: the outer rim of described wheel rim is U-lag, coordinates with steel rope; Described wheel rim inner side plane is provided with concave station endoporus, and is provided with some through holes in concave station face; The outer side plane of described wheel hub is provided with boss outer rim, and in boss face, is provided with some through holes; In the middle of described wheel hub, be provided with bearing hole, coordinate with plain bearing; After being coordinated by concave, convex table top when described wheel rim assembles with wheel hub, the some through holes with bolt through concave, convex table top, by nut and bolt tightening, become one wheel rim and wheel hub close-coupled.
