Abstract

The utility model relates to a universal shaft dismounting lifting tool for a vertical rolling mill, and is characterized in that the lifting tool comprises a C-shaped main body of the lifting tool which comprises an upper crossbeam, a lower crossbeam and a longitudinal beam perpendicularly and fixedly connected with the two crossbeams, the lower crossbeam consists of two strut beams which are fixedly connected at a certain angle, the length of the lower crossbeam is half or three fifth of the length of the upper crossbeam, a plurality of support plates are connected between the two strut beams of the lower crossbeam, and lifting lugs are arranged on the upper crossbeam in the positions close to the two ends. The universal shaft dismounting lifting tool for the vertical rolling mill has the advantages that the size of the lifting tool is remarkably reduced, and the position for lifting a shaft coupling is just below an overhead traveling crane, so as to dispense with counterweight installation, reduce lifting load and improve safety and reliability. The lifting tool adopt a C-shaped main body structure, which not only can greatly increase the operating freedom of operators, but also can accommodate several operators, improve the operating efficiency and shorten the universal shaft dismounting procedure.

Description

Vertical mill versatile spindle dismounting suspender
Technical field
The utility model belongs to the milling train mechanical field, particularly relates to a kind of vertical mill versatile spindle dismounting suspender.
Background technology
The versatile spindle of large-scale vertical milling train generally is mounted in the below of reductor, needs periodic replacement and dismounting in equipment operation.The method of operation of replacing and dismounting versatile spindle is to adopt the dismantling devices of shoulder pole beam type in the prior art, in operation, overhead traveling crane is by the steel rope shoulder pole girder that plays, shoulder pole girder one end is equipped with counterweight, the other end blocks the coupler education operation of milling train, because milling train coupler surrounding space is narrow and small, shoulder pole girder is long, and it is very inconvenient therefore to operate; Again owing to an end on shoulder pole girder is equipped with the counterweight that is used for the balance lifting operation, make the lifting load increase by one times so simultaneously, not only increased operating cost, but also had potential safety hazard.
Summary of the invention
The utility model provides a kind of simple in structure, vertical mill versatile spindle dismounting suspender that dismounting is easy and simple to handle and safe for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: vertical mill versatile spindle dismounting suspender, it is characterized in that: comprise by entablatrance and cross sill and the C shape suspender main body that constitutes with longeron that two beam vertical are connected, described cross sill is to be made of two affixed at an angle strutbeams, the length of cross sill is 1/2nd to 3/5ths of entablatrance length, and described entablatrance is provided with hanger near two ends.
The utility model can also adopt following technical scheme:
Angle between two strutbeams of described cross sill is 15-25 °.
Also be connected with several stay bearing plates between two strutbeams of described cross sill.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, dismounting suspender size is obviously dwindled, and when overhead traveling crane lifting coupler, the position of coupler be positioned at just overhead traveling crane under, need not to install again counterweight, reduce the lifting load, increased safe reliability.Because this suspender adopts C shape agent structure, so not only can strengthen the operation degree of freedom of operating personal, but also can hold many people's operations simultaneously, improve work efficiency, and then shortened the whole work efficiency of versatile spindle dismounting operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the K of Fig. 1 is to view;
Fig. 3 is the utility model working state schematic representation.
Among the figure: 1, entablatrance; 2, longeron; 3, cross sill; 3-1, strutbeam; 4, stay bearing plate; 5, hanger; 6, reductor; 7, versatile spindle crosshead; 8, versatile spindle.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, vertical mill versatile spindle dismounting suspender, comprise that described cross sill 2 is to be made of two affixed at an angle strutbeam 3-1 by entablatrance 1 and cross sill 2 and the C shape suspender main body that constitutes with longeron 3 that two beam vertical are connected, the angle between two strutbeams is 15-25 °.Also be connected with several stay bearing plates 4 between the two strutbeam 3-1 of described cross sill, the length of cross sill is 1/2nd to 3/5ths of entablatrance length, dismounting suspender size is obviously dwindled, and when overhead traveling crane lifting coupler, the position of coupler be positioned at just overhead traveling crane under, need not to install again counterweight, reduce the lifting load.Described entablatrance 1 is provided with the hanger 5 that is used to connect steel rope near two ends.
Principle of work of the present utility model is:
When using the utility model to carry out the dismounting of rolling mill universal axle, at first, utilize overhead traveling crane that the dismounting suspender is winched to rolling mill universal axle place, and two strutbeams of cross sill are fixed on the versatile spindle 8 that is positioned at reductor 6 and versatile spindle crosshead 7 bottoms, operating personal stands on the cardan shaft bracket position versatile spindle is implemented to change operation then.Because this suspender adopts C shape agent structure, so not only can strengthen the operation degree of freedom of operating personal, but also can hold many people's operations simultaneously, improve work efficiency, and then shortened the whole work efficiency of versatile spindle dismounting operation.
