Energy deviation is excessive, guarantees that each portion's bearing of unit is injury-free；It for another example needs repeatedly to replace suspender position in main shaft disassembly process
It sets, needs a variety of dedicated lifting auxiliary tools.
Utility model content
The purpose of this utility model is that in view of the above-mentioned drawbacks in the prior art, it is simple to provide a kind of structure, is suitable for
The disassembly of horizontal hydrogenerator main shaft, the horizontal hydrogenerator main shaft that main shaft disassembly safety and feasibility can be improved is torn open
Handler.
To realize above-mentioned purpose of utility model, the utility model uses following technical solution：A kind of horizontal hydraulic power generation
Machine disassembling device for main shaft, the provision for disengagement include main support base, adjusting nut, adjust bolt, supporting block and support plate, wherein
One through-hole is set at the center of main support base the top；Adjusting nut is fixedly installed on main support base, and is matched with the through-hole；It adjusts
Section bolt is threadedly coupled with adjusting nut and passes through the through-hole on main support base, and it is also mutually detachable with supporting block to adjust bolt
Connection；Supporting block is fixedly installed on the middle position of support plate convex surface side；Support plate is arc-shaped, radian and to be removed
The outer circle radian of main shaft is consistent.
Preferably, adjusting bolt has interconnecting piece, threaded portion and square head portion, and interconnecting piece is non-threaded, mutual with supporting block
It is detachably connected, there is external screw thread in threaded portion, is threadedly coupled with adjusting nut, and square spigot is used to be coupled with external tool.
Preferably, supporting block upper surface is arcwall face, which connect with support plate, and lower end surface setting is fluted, should
Groove is for adjusting bolt insertion.
Compared with the prior art, the advantage of the utility model is：The device includes main support base, adjusting nut, adjusting
The advantages such as bolt, supporting block and support plate have structure simple, materials convenience, and cost of manufacture is cheap, but also meet lifting
Required strength and stiffness requirement when main shaft, more effectively guarantees the stability and reliability of main shaft in main shaft hoisting process, with
And it is horizontal, effectively improve the safety and feasibility of main shaft disassembly.
Detailed description of the invention
In order to illustrate more clearly of the technical solution of the utility model embodiment, embodiment or the relevant technologies will be retouched below
Attached drawing needed in stating is briefly described, it should be apparent that, it is practical new that the accompanying drawings in the following description merely relates to this
Some embodiments of type, are not limitation of the utility model.
Fig. 1 is the exploded view of the provision for disengagement of the utility model preferred embodiment.
Fig. 2 is the assembling sectional view of the provision for disengagement of the utility model preferred embodiment.
Specific embodiment
In order to be more clearly understood that the above objects, features, and advantages of the utility model, with reference to the accompanying drawing and have
Body embodiment makees further unrestricted detailed description to technical solutions of the utility model.
See that Fig. 1 and Fig. 2, the horizontal hydrogenerator disassembling device for main shaft of the present embodiment include：Main support base 1 adjusts spiral shell

Main support base 1 is welded by angle steel, channel steel, round steel, steel plate, mainly plays load-bearing effect, the top steel plate center
Place's setting one Ф, 104 through-hole, the screw hole sizableness with adjusting nut 2, and for adjusting passing through for bolt 3.
Adjusting nut 2 is welded at main 1 center of support base, and the screw hole of adjusting nut 2 is aligned with the through-hole of main support base 1.
It adjusts bolt 3 and uses M100*4*175 bolt, with interconnecting piece, threaded portion and square head portion.Interconnecting piece length
30mm, it is non-threaded, it can be mutually detachably connected with supporting block.There is external screw thread in threaded portion, can be threadedly coupled with adjusting nut.It is rectangular
Head specification is 46*46, for being coupled with external tool.
The upper surface of supporting block 4 is arcwall face, and radian is consistent with curved support plate, which connect with support plate,
The present embodiment uses welding manner.The lower end surface of supporting block 4 is provided with circular groove, and groove size is Ф 101*30, the groove
It is inserted into for adjusting bolt 3, it is detachable between each other.
Support plate 5 contacts with each other with main shaft, for lifting main shaft.Support plate 5 is arc-shaped, radian and set main shaft outer circle
Radian is consistent.
The method for carrying out horizontal hydrogenerator main shaft dismantlement work using above-mentioned provision for disengagement is as follows：
1) prepare above-mentioned provision for disengagement；
2) above-mentioned provision for disengagement is assembled and is completed；
3) lower section of desired position when the provision for disengagement assembled being placed on main shaft lifting, by adjusting bolt adjustment
The height of support plate is in close contact the concave side of support plate and main shaft, guarantees that main shaft is maintained at a horizontal state；
4) when needing to support again after main shaft lifting, provision for disengagement is moved to required position, adjusts height
After place main shaft, until main shaft disassembly finish.
According to above-mentioned introduction, same reason, the horizontal hydrogenerator main shaft method for dismounting of the present embodiment introduction are utilized
The installment work of horizontal hydrogenerator main shaft is equally applicable to provision for disengagement.
It should be pointed out that above-mentioned preferred embodiment is only to illustrate the technical ideas and features of the present invention, purpose
