Abstract
The utility model discloses an upper bearing beam structure of a mechanical grab bucket. The upper bearing beam structure comprises an upper bearing beam body, wherein an upper pulley shaft is arranged on the upper bearing beam body; a pulley block is arranged on the upper pulley shaft; a pulley box support plate and a balance device for holding a steel wire rope are further arranged on the upper bearing beam body; the steel wire rope is fixedly arranged on the balance device; the balance device is positioned on the outer side of the pulley box support plate and is arranged on the end part of the upper pulley shaft. According to the upper bearing beam structure, as the balance device is arranged on the outer side of the pulley box support plate, the steel wire rope can be conveniently assembled and disassembled, the difficulty in replacing the steel wire rope is alleviated, the time for assembling and disassembling the steel wire rope is shortened, and the production efficiency is improved.
Description
Technical field
The utility model relates to mechanical grab bucket field, relates in particular to a kind of machinery grab bucket deck beam structure.
Background technology
The grab bucket of machinery double-jaw is in the carriers such as port and pier, power plant, to use comparatively general a kind of bulk handling device, as everyone knows, the grab bucket of mechanical double-jaw it by bucket lobe, deck beam and fixed pulley group, cross sill and running block, four struts, sheave, equalizer bar, steel rope etc., formed.Due to the difference of grab multiple, in assembly pulley, include the pulley of different numbers.The drive of steel rope by pulley make to struggle against lobe closed with open.
At present, the deck beam of four conventional multiplying power machinery grab buckets, it installs the inner side that steel rope balancing device used is all installed on pulley casing back plate, because of the obstruction of back plate, causes the very inconvenience of dismounting steel rope.
Utility model content
For the problems referred to above, the utility model provides a kind of machinery grab bucket deck beam structure, to solve the problem of the steel rope dismounting inconvenience of machinery grab bucket in prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of machinery grab bucket deck beam structure, comprise deck beam beam body, on this deck beam beam body, be provided with top sheave axle, on top sheave axle, be provided with assembly pulley, on deck beam beam body, be also provided with pulley casing back plate, for the balancing device of steel rope is installed, wire rope fixing device is arranged on described balancing device, it is characterized in that, described balancing device is positioned at the outside of pulley casing back plate, and balancing device is arranged on the termination of top sheave axle.
In a preferred embodiment of the present utility model, balancing device is mounted on the termination of top sheave axle by spindle nose pressing plate and socket head cap screw.
In a preferred embodiment of the present utility model, pulley casing back plate is arranged on top sheave axle by lining.
In a preferred embodiment of the present utility model, balancing device is contained in the lining on pulley casing back plate, and keeps lubricating status between balancing device dress and lining.
In a preferred embodiment of the present utility model, wire rope fixing device is installed on balancing device by bearing pin.
The utility model is by balancing device being installed on to the outside of pulley casing back plate, thereby can easy disassembly steel rope.Reduce the more difficulty of change steel rope, save the time of dismounting steel rope, enhance productivity.
Feature of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained and be well understood to.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to generalized section.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the utility model.
Referring to Fig. 1 and 2, a kind of machinery grab bucket deck beam structure, comprise deck beam beam body, on this deck beam beam body, be provided with top sheave axle 06, assembly pulley 05 is installed on top sheave axle, the arranged outside of assembly pulley 05 has pulley casing back plate 01, and pulley casing back plate 01 is arranged on top sheave axle 06 by lining 07.
Balancing device is positioned at the outside of pulley casing back plate, and balancing device 02 is mounted on the termination (each, two ends) of top sheave axle by spindle nose pressing plate 09 and socket head cap screw 10.Balancing device is contained in the lining 07 on pulley casing back plate 01, and keeps lubricating status between balancing device dress and the inner ring of lining.Balancing device (02) can be swung freely.It is upper that wire rope fixing device (03) is installed on balancing device (02) by bearing pin (08), more needs first wire rope fixing device (03) is disassembled during change steel rope.Wire rope fixing device (03) is placed in pulley casing back plate outside and is convenient to dismounting.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification sheets, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
