Description

Well style of calligraphy grab bucket rope sheave

Technical Field

The utility model belongs to freight transportation hoist field, especially a well style of calligraphy grab bucket rope sheave.

Background

With the increase of the kinds of goods arriving at the port, the equipment for loading and unloading bulk cargo, namely the bivalve grab bucket, has increasingly wide application range and becomes the main equipment for loading and unloading bulk cargo at the port. The structure of the wire guide wheel (wire guide wheel) frame, which is one of the main parts of the grab bucket, plays an important role in guiding the transmission steel wire rope in the operation process of the grab bucket, and the wire guide wheel belongs to a typical vulnerable part. Meanwhile, the wire wheel frame is positioned at the top of the upper beam of the grab bucket and is higher than the ground, so that the wire wheel frame is difficult to maintain and replace, the bearing is difficult to inject oil daily, and certain danger exists in the operation.

The existing wire wheel carrier is cross-shaped, see fig. 4 and fig. 5 (no marking is carried out on the steel wire rope), that is, four wheel carriers 13 arranged in a cross shape are arranged on a base 11 provided with a threading hole 14, a rotating shaft 12 is coaxially sleeved on each wheel carrier through a bearing with an oil filling hole 10, a roller is coaxially sleeved on the rotating shaft, and the roller is used as a pulley to guide the steel wire rope.

In the actual use process, because the four wheel frames are on the same plane, the steel wire rope is easy to stagger and rub and wear, and is easy to wear, and meanwhile, the load of the wire guide wheel and related rotating parts is increased, so that the maintenance is difficult, the replacement frequency is high, the structure is complex, and the cost is high.

Based on the above problems, a new structure is urgently needed to replace the old structure, thereby effectively reducing the cost, lightening the working strength of operators, reducing the maintenance and replacement frequency and prolonging the service life of the device.

Through searching, the patent documents which are the same as the technical field and technical scheme of the patent application are not found.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a working strength who alleviates operating personnel, reduce the maintenance and change the frequency, extension device's life's well style of calligraphy grab bucket rope guide pulley.

The utility model adopts the technical proposal that:

a # -shaped grab bucket rope guide wheel comprises two short shaft seats, a short shaft, short shaft rollers, long shaft seats, a long shaft, long shaft rollers, short shaft bearings and long shaft bearings, wherein the two short shaft seats are arranged in parallel, two pairs of parallel and coaxial short shaft bearings are fixedly arranged on the inner walls of the two sides of the two short shaft seats, the short shaft is coaxially sleeved between each pair of short shaft bearings, the short shaft rollers are coaxially sleeved on the short shaft, two long shaft seats are fixedly arranged on the two short shaft seats in parallel, the two short shaft seats and the two long shaft seats are arranged in a # -shape, two pairs of parallel and coaxial long shaft bearings are fixedly arranged on the inner walls of the two sides of the two long shaft seats, the long shaft is coaxially sleeved between each pair of long shaft bearings, the long shaft rollers are coaxially sleeved on the long shaft, the two side ends of each short shaft roller and the short shaft bearings on the two sides are respectively embedded, and the two side ends of each long shaft roller and the long shaft bearings on the two sides are respectively embedded.

And a steel wire rope penetrates through a gap between the two short shaft seats and the two long shaft seats.

The bearing material is nylon MC 60.

The utility model discloses the advantage does with positive effect:

the utility model provides a well style of calligraphy grab bucket rope guide wheel simple structure is reasonable, through the layering, the staggered floor wire has been realized with four wire wheels, make wire rope friction between wire rope can not appear at the direction slidingtype, the heavy burden of wire wheel and axis of rotation and bearing has been reduced, the layered structure based on this patent application provides simultaneously, the structure to the bearing has also been improved, it is wear-resisting to replace the bearing for the nylon bearing, artificial oiling has been saved, the non-maintaining of daily use has been realized, make whole equipment non-maintaining from this, the maintenance, change the frequency low (about grabbing material 10 ten thousand tons maintenance or change once), long service life, low cost, economical and practical.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention is not limited thereto.

A # -shaped grab bucket wire wheel carrier comprises short shaft seats 6, short shafts 4, short shaft rollers 7, long shaft seats 2, long shafts 3, long shaft rollers 1, short shaft bearings 5 and long shaft bearings 8, wherein the short shaft seats are arranged in parallel, two pairs of parallel and coaxial short shaft bearings 5 are fixedly arranged on the inner walls of two sides of the two short shaft seats, the short shafts are coaxially sleeved between each pair of short shaft bearings, the short shaft rollers are coaxially sleeved on the short shafts, two side ends of each short shaft roller are respectively embedded with the short shaft bearings 5 on two sides, two long shaft seats are fixedly arranged on the two short shaft seats in parallel, the two short shaft seats and the two long shaft seats are arranged in a # -shape, two pairs of parallel and coaxial long shaft bearings 8 are fixedly arranged on the inner walls of two sides of the two long shaft seats, the long shafts are coaxially sleeved between each pair of long shaft bearings, the long shaft rollers are coaxially sleeved on each long shaft, two side ends of each long shaft roller are respectively embedded with the long shaft bearings 8 on two sides, the long shaft seat and the short shaft seat are arranged to realize the dislocation of a certain angle between the shaft seat and the shaft which are arranged up and down, and a steel wire rope can penetrate through a gap between the two short shaft seats and the two long shaft seats.

The short shaft bearing and the long shaft bearing are made of nylon MC60, and are in running-in with the shaft when in use, and the running-in parts are brightened to generate grease which plays a role in lubrication. The nylon sleeve made of the material saves manual oil injection, and realizes maintenance-free daily use.
