Description
Technical field
The utility model relates to water power field, more particularly, to pull pin in the maintenance of power station nail, dismounting connecting lever and guide vane
The tool of sleeve.
Background technique
In the maintenance of power station, nail of pulling pin, dismounting connecting lever and guide vane sleeve are all one of conventional projects.
It is existing to pull out the sleeve that pin method is usually the suitable dimension in pin upper cover, it penetrates screw and is screwed into pin correspondence
Screw hole, screw tightening process drive pin extract, the disadvantage is that being not easily found the sleeve and screw of suitable dimension, and pin hole
Screw thread is easy stripped thread.
The existing method for removing connecting lever is removed in the jacking of connecting lever undercarriage hydraulic top, the disadvantage is that two hydraulic liftings
Position can not be completely the same, the bad control of top lifting height on two tops, is easy to happen the inclined phenomenon in top, grinds connecting lever and guide vane teunnion
Damage.
The existing method for removing guide vane sleeve is with jackscrew by sleeve top pine, then is hung and hung away with annular, the disadvantage is that using
It is impaired that jackscrew is easy the position for making top cover correspond to top wire hole, and jackscrew jacks up limited height, and guide vane sleeve often can not be primary
It hangs out.
Utility model content
The utility model proposes nail of pulling pin in overhauling for power station, the tool of connecting lever and guide vane sleeve is dismounted, using setting
The specific purpose tool of meter has nail of pulling pin, dismounting connecting lever, dismounting five kinds of functions of sleeve.
The utility model is achieved through the following technical solutions:
For the tool of pull pin in the maintenance of power station nail, dismounting connecting lever and guide vane sleeve, there is tool body, the tool
Ontology tool is connected and fixed to form the upper of tool body by several connectors there are two the vertical plate that is symmetrically set between vertical plate
Surface and lower surface, form several through-holes through upper and lower surfaces between connector and vertical plate, the through-hole includes extremely
A few mesoporous being located in the middle part of vertical plate and at least two is located at the lateral opening of vertical plate both ends.
Preferably, the tool body is integrally formed.
Preferably, the tool body is in cuboid.
Preferably, the connector have 4, every two in one group formed it is lateral opening, two it is lateral opening symmetrically, it is adjacent
Two groups between form mesoporous.
Preferably, the upper and lower surfaces of the tool body are parallel to each other and vertical with through-hole central axes.
Preferably, the vertical plate is provided centrally with perforative cross-drilled hole.
Preferably, also having matching used screw rod, nut and jack.
The utility model practicability in power station is overhauled is very strong, has extensive popularization and application space, and more efficient, single
A connecting lever and guide vane sleeve dismount personnel and are reduced to 3 people by 5 people, and dismounting difficulty is substantially reduced, and the time greatly shortens, securely and reliably
Property is higher.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1 and Figure 2, the tool for pull pin in the maintenance of power station nail, dismounting connecting lever and guide vane sleeve, has one
Body formed tool body 1, the tool body 1 tool is there are two the vertical plate 2 being symmetrically set, by several between vertical plate 2
Connector 3 is connected and fixed the upper surface 4 and lower surface 5 to form tool body 1, and several run through is formed between connector 3 and vertical plate 2
The through-hole of upper surface 4 and lower surface 5, the through-hole include that at least one mesoporous 6 and at least two for being located at 2 middle part of vertical plate is located at
Lateral opening the 7 of 2 both ends of vertical plate；The upper surface 4 and lower surface 5 of the tool body 1 are parallel to each other and vertical with through-hole central axes.
In the present embodiment, the tool body 1 is in cuboid.
In the present embodiment, the connector 3 has 4, and every two forms lateral opening 7 in one group, and two lateral opening 7 mutually right
Claim, forms mesoporous 6 between adjacent two groups.
In the present embodiment, the vertical plate 2 is provided centrally with perforative cross-drilled hole 8.
In the present embodiment, also there is matching used screw rod (Fig. 3), nut and jack 9, can according to need selection not
