In a further scheme, a limiting step for supporting the rear end cover is arranged on the threaded shaft.
In a preferred scheme, the material of the threaded shaft is 45 # steel.
In a preferable scheme, the diameter of the threaded shaft is 70-80 mm.
The utility model provides a hydro-generator mirror plate hoisting and turning-over tool, this novel mirror plate hoisting and turning-over tool simple structure compares traditional hoist, can avoid the mirror plate and thrust collar faying face edge to suffer the impaired phenomenon of wire rope extrusion and take place when lifting by crane, has protected the mirror plate betterly, has also avoided the coping work of the impaired position of mirror plate; the novel mirror plate hoisting and turning tool can bear radial and axial forces simultaneously due to the tapered roller bearing, and the rolling friction of the novel mirror plate hoisting and turning tool is small compared with the sliding dry friction of a steel wire rope and a lifting appliance, so that the working strength of constructors when the mirror plate turns is reduced.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of the present invention;
in the figure: the device comprises a mirror plate 1, a threaded shaft 2, a cross shaft lifting lug 3, a shackle 4, a lifting lug hole 5, a mounting hole 6, a bearing 7, a shaft shoulder 8, a limiting front end cover 9, a limiting rear end cover 10 and a limiting step 11.
Detailed Description
As shown in fig. 1-2, a hydraulic generator mirror plate hoisting and turning tool comprises a threaded shaft 2 matched with threaded holes on the whole body of a mirror plate 1, wherein the rear end of the threaded shaft 2 is in threaded connection with the threaded holes on the whole body of the mirror plate 1, a cross shaft lifting lug 3 is arranged at the front end of the threaded shaft 2, a lifting lug hole 5 for installing a shackle 4 is arranged at the upper end of the cross shaft lifting lug 3, an installation hole 6 for installing the threaded shaft 2 is arranged at the lower end of the cross shaft lifting lug, and the threaded shaft 2 is rotatably installed in the installation hole 6 through a bearing 7. The bearing 7 is a tapered roller bearing.
When the tool is used specifically, as shown in fig. 2, four tools are arranged and symmetrically arranged around the mirror plate 1, and during hoisting, a hoisting hook or a steel wire rope is connected with a shackle 4 arranged on a lug hole 5, so that the mirror plate 1 is hoisted, the phenomenon that the edge of the joint surface of the mirror plate 1 and a thrust head is damaged due to extrusion of the steel wire rope during hoisting can be avoided, the mirror plate is well protected, and the grinding work of the damaged part of the mirror plate is also avoided; when the mirror plate needs to be turned over, the lifting hook or the steel wire rope is connected with the two symmetrically arranged tools, and the threaded shaft 2 is rotatably arranged in the mounting hole 6 at the lower end of the cross shaft lifting lug 3 through the bearing 7, so that the turning-over friction force is small, and the working strength of constructors is reduced when the mirror plate turns over.
Preferably, the axes of the lug hole 5 and the threaded shaft 2 are cross-shaped. After the installation, the shackle 4 is stressed reasonably and normally rotates in the lifting lug hole 5, and unreasonable bending moment cannot be borne.
Preferably, a shaft shoulder 8 is arranged on the threaded shaft 2, and the thread section on the threaded shaft 2 is distributed from the shaft shoulder 8 to the rear end of the threaded shaft 2. The shaft shoulder 8 ensures that the mirror plate 1 has enough rotating space when turning over, and avoids interference with a lifting appliance.
Preferably, the front end and the rear end of the lug hole 5 are respectively provided with a limiting front end cover 9 and a limiting rear end cover 10. The limiting front end cover 9 is locked with the end part of the threaded shaft 2 through a screw. The limiting front end cover 9 and the limiting rear end cover 10 play a role in limiting and preventing dust for the bearing 7.
And a limiting step 11 for supporting the rear end cover 10 is arranged on the threaded shaft 2. One side of the rear end cover 10 is abutted against the limiting step 11, and the limiting step 11 limits and supports the rear end cover 10.
In this embodiment, the threaded shaft 2 has a thread section with a size of M80 × 6 and a length of 120mm, so as to ensure a sufficient fit length and stress strength with the threaded hole of the mirror plate itself.
The diameter of the optical axis section of the threaded shaft 2 is phi 70mm, the maximum stress is 258MPa, and the material is No. 45 steel which is smaller than the yield limit of 355MPa, so that the strength requirement is met.
When the lifting appliance is installed, the rear end cover 10, the bearing 7 and the cross shaft lifting lug 3 are sequentially assembled in a matching mode, and finally the limiting front end cover 9 is fastened on the threaded shaft 2 through M8 locking screws, so that an assembly whole is formed. When the mirror plate turnover device is used on site, 4 lifting appliances are installed and matched with shackles to lift the mirror plate, and when the mirror plate is turned over, the mirror plate can be easily turned over by only using 2 lifting appliances under the rolling friction of the conical mixer bearing.
