Description
Technical field
The utility model is related to a kind of device for being used to efficiently install the stator blade bearing of TRT generating sets, belongs to workshop work
Has technical field.
Background technology
TRT generating sets were run after a period of time, and stucking phenomena just occurs in its stationary blade regulating mechanism, so as to influence turbine
Unit can also substantially reduce the generating efficiency of unit to the control accuracy of blast furnace top pressure when serious, so annual big
During repairing, stator blade bearing can all be checked, be cleared up；The stator blade bearing of damage is changed.But due to currently without
Special installation tool, the difficulty for changing stator blade bearing is very big, should tap new stator blade bearing and arrive specified location, again
Ensure stator blade bearing on bolt hole it is relative with the fastening bolt studding hole on pedestal, therefore a stator blade bearing generally require it is many
Secondary refitting can be just installed in place, and not only greatly reduce the overhaul efficiency of TRT generating sets, and be easily damaged stator blade bearing,
Bigger economic loss is caused to enterprise.
Utility model content
The purpose of this utility model is there is provided a kind of TRT generating sets stator blade bearing to pacify for the drawback of prior art
Holding tool, to improve the overhaul efficiency of TRT generating sets.
Problem described in the utility model is realized with following technical proposals：
A kind of TRT generating sets stator blade bearing installing tool, composition includes stator blade Bearing housing and two guide rods, two
Root guide rod is each passed through two bolts hole of stator blade bearing to be installed, and the lower end of the two is provided with and the fastening spiral shell on bearing base
The screw thread that bolt studding hole matches；The stator blade Bearing housing is drum, and end seal is blocked up thereon, and lower end withstands on to be installed quiet
Rachis is held, and the both sides of stator blade Bearing housing are provided with the axial groove corresponding with two guide rods.
Also include the annular coaxial with stator blade Bearing housing in above-mentioned TRT generating sets stator blade bearing installing tool, composition
Rubber blanket, the rubber blanket is placed on stator blade Bearing housing between stator blade bearing to be installed.
Above-mentioned TRT generating sets stator blade bearing installing tool, the inwall of the stator blade Bearing housing is provided with nylon bush.
Above-mentioned TRT generating sets stator blade bearing installing tool, the upper end side of the stator blade Bearing housing is provided with hand rod.
Above-mentioned TRT generating sets stator blade bearing installing tool, the outside of the hand rod is provided with rubber shock-absorbing sleeve.
The utility model passes to the percussion power of sledgehammer using stator blade Bearing housing on stator blade bearing to be installed, using leading
Ensure that the fastening bolt studding hole on bolt hole and pedestal on stator blade bearing is aligned to the guide effect of bar.The utility model can
To ensure the success of stator blade bearing once mounting, so as to substantially reduce the set-up time of stator blade bearing, TRT generating sets are improved
Overhaul efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure as follows：1st, hand rod, 2, guide rod, 3, stator blade Bearing housing, 4, rubber blanket, 5, nylon bush.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model mainly includes hand rod 1, guide rod 2, stator blade Bearing housing 3, rubber blanket 4 and nylon
Bushing 5.Stator blade bearing to be installed can be pressed onto specified location by stator blade Bearing housing 3 under the percussion of sledgehammer.
Assembling process of the present utility model is as follows：
In the centre bore that nylon bush 5 is installed to stator blade Bearing housing 3（The two is interference fitted）, prevent from striking with sledgehammer
When hitting stator blade Bearing housing 3, the slight deformation of stator blade Bearing housing 3 destroys the carbocyclic ring outer of stator blade bearing.
Two guide rods 2 are arranged in the fastening bolt studding hole on stator blade bearing base, by 4 sets of the rubber blanket of annular
It is pressed onto on stator blade bearing, then by the assembly of stator blade Bearing housing 3 and nylon bush 5 on rubber blanket 4.
The use of guide rod 2 can ensure that the step of stator blade bearing one is installed in place.Stator blade bearing is prevented to be installed to behind bottom, stator blade
Holding down bolt can not be inserted.Because stator blade bearing and pedestal coordinate close, it can not be adjusted after squeezing into, fastening bolt can not be inserted
Fashionable can only type it out stator blade bearing is reinstalled, and the risk of destruction stator blade bearing can be greatly increased like that, and when installing
Between it is longer.Safety when nylon bush 5 and rubber blanket 4 can ensure that new stator blade bearing is installed with 100%.
Note：1. guide rod 2 of the present utility model have two just can be with, but preferably prepare 4 in real work and arrive
5, one is standby, in addition two can in a pre-installation a stator blade bearing when, in advance installed in next mount point, to improve peace
Fill efficiency.
Use step of the present utility model is：
1. bar is directed in the pedestal studding hole of stator blade bearing to be installed；
2. stator blade bearing lower end is gently put into pedestal, directly by two bolts hole of new stator blade bearing through two guide rods
Untill it can not be pushed into manually, its level is simply observed；
3. rubber blanket 4 is inserted in into stator blade bearing upper end, then compressed with stator blade Bearing housing 3, now two guide rods are proper
Well in the axial groove of the both sides of stator blade Bearing housing 3；
4. a human hand handrail handrail, is firmly pressed downward, stator blade Bearing housing 3 is compressed into stator blade bearing；Another person exerts oneself
Stator blade Bearing housing 3 is pounded, when stator blade bearing is soon attached to, guide rod is removed, fastening bolt is installed；Then proceed to pound stator blade
Bearing housing 3, until stator blade bearing in place after, tighten fastening bolt.
It was verified that during the utility model thoroughly solves TRT maintenance for generation companies, the stator blade bearing set-up time is long
The problem of, substantially increase efficiency, great generalization.
