Description
Technical field
The utility model belongs to special purpose vehicle and manufactures field, relates in particular to a kind of automatic compacting device of crane hoisting wire rope.
Background technology
Hoist rope is as the important lifting component of crane, but at lifting operation process due to arm body length restriction, when unloaded steel wire rope with the effect of assembly pulley frictional force under tensioning completely, in the time of crane retraction steel wire rope, arm body section steel wire rope can produce violent shake, thereby causes hoisting rope to depart from its fixing coiling groove, is squeezed on the steel wire rope of having reeled, cause and weigh wounded, affect rope service-life; In the time of retraction crane arm, arm body section steel wire rope can because arm body spacing reduces, surplus can be increasing, hoisting rope just can be fluffy, in the time again starting elevator winding, will produce disorder cable, cause steel wire rope to produce the distortion such as waveform, kink, bending, to such an extent as to cause steel wire rope to scrap; These phenomenons can affect the security of crane job. We have designed a kind of automatic compacting device of crane hoisting wire rope for this reason.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic compacting device of crane hoisting wire rope, weigh wounded to solve the crane hoisting mechanism steel wire rope that steel wire rope, contracting arm etc. cause of retracting when unloaded, the phenomenons such as distortion, strengthen crane work security, stability.
It is to implement like this that the utility model solves the technical scheme that its technical problem adopts, a kind of automatic compacting device of crane hoisting wire rope, comprise gripper shoe, base plate, rubber rollers, sliding axle, bearing, check ring, spring, fixed axis, it is characterized in that: in gripper shoe, be provided with circular hole, U-shaped hole, spring mounting hole, gripper shoe is welded on the both sides composition bracing or strutting arrangement of base plate; Rubber rollers is arranged on the rolling roller forming on fixed axis by bearing, check ring, rolling roller is arranged in the circular hole in gripper shoe by fixed axis; Rubber rollers is arranged on sliding axle and is formed slide roller by bearing, check ring, and slide roller is arranged on by sliding axle in the U-shaped hole of gripper shoe; Slide roller and rolling roller are arranged on bracing or strutting arrangement, and both ends of the spring respectively has a hook, is hung on bracing or strutting arrangement and sliding axle, forms this device.
Above-described sliding axle two ends have circular trough.
The horizontal range at above-described slide roller and rolling roller center is less than the diameter of steel wire rope.
The utility model, can be by increasing the quantity of slide roller and rolling roller along with the increase of crane nominal load capacity.
The utlity model has simple in structure, avoided the distortion of steel wire rope in the time that shake, job-hopping and the crane arm of hoisting type are retracted, increased the service life of steel wire rope and the advantage such as security, stability of car load.

In figure: 1. gripper shoe, 2. base plate, 3. rubber rollers, 4. sliding axle, 5. bearing, 6. check ring, 7. spring, 8. fixed axis, 9. steel wire rope.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of automatic compacting device of crane hoisting wire rope, comprise gripper shoe 1, base plate 2, rubber rollers 3, sliding axle 4, bearing 5, check ring 6, spring 7, fixed axis 8, it is characterized in that: in gripper shoe 1, be provided with circular hole, U-shaped hole, spring 7 installing holes, gripper shoe 1 is welded on the both sides composition bracing or strutting arrangement of base plate 2; Rubber rollers 3 is arranged on fixed axis 8 and is formed rolling roller by bearing 5, check ring 6, and rolling roller is arranged in the circular hole in gripper shoe 1 by fixed axis 8, and rotates relative to fixed axis 8, ensures that steel wire rope 9 passes through smoothly; Rubber rollers 3 is arranged on sliding axle 4 and is formed slide roller by bearing 5, check ring 6, and slide roller is arranged on by sliding axle 4 in the U-shaped hole of gripper shoe 1; Slide roller and rolling roller are arranged on bracing or strutting arrangement, and spring 7 is fixed on bracing or strutting arrangement and sliding axle 4, forms this device.
Above-described sliding axle 4 two ends have circular trough.
The horizontal range at above-described slide roller and rolling roller center is less than the diameter of steel wire rope 9.
The utility model, can be by increasing the quantity of slide roller and rolling roller along with the increase of crane nominal load capacity.
Embodiment: crane is in the time hoisting suspension hook, steel wire rope 9 passes through between slide roller and rolling roller, slide roller is in the effect of spring 7, all the time steel wire rope 9 is pressed to rolling roller, steel wire rope 9 is produced to certain extruding force, time arm body section steel wire rope 9 have certain rate of tension, avoid steel wire rope 9 to produce shake, job-hopping, and neat, be closely arranged on winching barrel.
When the gib arm of crane is retracted, due to the effect of extruding force, the surplus of steel wire rope 9 remains at the leading portion of hold down gag, between the rear end of hold down gag and elevator, remain tensioning state, while making steel wire rope 9 contracting arm, be unlikely to surplus excessive and disorder cable phenomenon occurs, thereby avoid steel wire rope 9 to be out of shape, increase the service life of steel wire rope 9 and the security of car load.
Crane is in the time of lift heavy thing, and slide roller upward sliding, reduces gradually to the extruding force of steel wire rope 9, makes the slow tensioning of steel wire rope 9, thus while having alleviated hoisting heavy to steel wire rope 9 impulsive forces, increase whole vehicle stability.
