Abstract
The invention discloses a rotatable multi-stage swing reducing device of a crane, which comprises a fixed cylinder fixedly arranged below a cantilever, wherein the middle part of the fixed cylinder is rotatably provided with a rotary cylinder, the center of the rotary cylinder is just opposite to the guide of a steel wire rope on a fixed pulley, the lower end of the fixed cylinder is provided with a connecting seat, the middle part of the connecting seat is provided with a through hole, the upper end of the through hole is communicated with a damper mounting hole, the through hole at the lower end part of the connecting seat is rotatably provided with a rotary disc, the bottom end of the rotary disc is connected with a cylinder body, the bottom end surface of the cylinder body is provided with a limiting groove, the bottom end of the cylinder body is connected with a limiting ring through a connecting plate, one end of the connecting. The invention has reasonable structural design, ensures the normal conveying of the steel wire rope, and limits the parts to be sequentially reduced from the lower end to the upper end when the steel wire rope deflects, thereby weakening the swing of the steel wire rope and further achieving the aim of reducing the swing.
Description
Technical field：
The present invention relates to crane field, relates generally to a kind of multistage shimmy damping device of rotary type crane.
Background technology：
Crane tool has the advantages that maneuverability, easy to operate, efficiency high.But crane is during lifting job object,
The swing of work object is always the problem for needing to solve.
Traditional crane is all to put down steel wire by the reel on electric block in materials handling process is carried out, generally
Rope carries out lifting carrying to lifting material, as steel wire rope is soft, so during lifting, from extraneous factor
Or the operation technique of operator is improper, may result in lifting material and the rocking of direction all around occur, with surrounding
There is collision in machine or object, cause some inevitably to lose, if there is also steel wire rope race when waving excessive serious
Partially, material is due directly to gravity fall, and impact is normal to be used, and when lifting positioning is carried out, if shaking occurs in lifting material
Dynamic, just cannot fast and accurately position, reduce work efficiency；Therefore it provides a kind of simple structure, height easy to use, safe
Effect, can effectively reduce the crane shimmy damping device for waving and be very important.
Content of the invention：
The object of the invention be exactly in order to make up the defect of prior art, provide a kind of rotary type crane multistage shimmy damping device.
The present invention is achieved by the following technical solutions：
A kind of multistage shimmy damping device of rotary type crane, it is characterised in that：Include the fixation being fixedly mounted on below cantilever
Cylinder, the middle part of the fixed cylinder is rotatablely equipped with a rotating cylinder, and the center of the rotating cylinder is right against the guiding of steel wire rope on fixed pulley,
The lower end of the fixed cylinder is provided with connecting seat, and the middle part of the connecting seat is provided with through hole, and the upper end of the through hole is communicated with resistance
Buddhist nun's device installing hole, and antivibrator is installed in antivibrator installing hole, it is rotatablely equipped with the through hole of the connecting seat bottom
Disk, the bottom of the rotating disk is connected with cylinder, and the bottom face of the cylinder is provided with stopper slot, and the bottom of the cylinder is by even
Fishplate bar connects restraining position ring block, and described connecting plate one end is hinged on cylinder bottom, and the other end is hinged on spacing ring, the cylinder bottom
Also extension spring is distributed between end and spacing ring, the extension spring and connecting plate interval setting.
Upper and lower port portion is provided with described rotating cylinder and is respectively adopted arc-shaped transition, and its oral area is coated with rubber layer.
Be distributed with described cylinder bottom face with body centre as the center of circle along eight directions of radial direction stopper slot, and
Stopper slot is mutually corresponding and is distributed on cylinder bottom face.
The size of described spacing ring is the twice of stopper slot.
During use, steel wire rope sequentially pass through rotating cylinder in the fixed cylinder below cantilever, the through hole of connecting seat, rotating disk, cylinder,
The stopper slot of cylinder bottom and spacing ring, by the structure of above-mentioned multi-stage rotary, on the one hand can ensure the normal of steel wire rope
Conveying, on the other hand when steel wire rope is deflected in the effect for being subject to external force, what which was reduced from lower end to upper end successively enters
Row is spacing, and the load of steel wire rope can be entered by the structure of antivibrator and rotating cylinder, rotating disk, stopper slot and spacing ring and extension spring
Row buffering, reduces the swing of steel wire rope, subtracts pendulum purpose so as to reach.
It is an advantage of the invention that：
Present configuration is reasonable in design, it is ensured that the normal conveying of steel wire rope, and when which deflects, each part is to which from lower end
Spacing to carrying out of reducing successively of upper end, the swing of steel wire rope is reduced, subtracts pendulum purpose so as to reach.
