Compared with the prior art, the utility model discloses an use of sleeve and dead lever, the danger of dropping of screw bolt and nut when having avoided the dismouting, the dismouting is fast, and generator idle time is few, and installation fastening nature is good, and the reliability is high, light in weight, convenient operation.
Description
Technical field
This utility model relates to a kind of hand-operated tools for dismounting, and especially relates to a kind of high reliability power generator air gap baffle plate rapid dismounting apparatus.
Background technology
In generator maintenance technique, it is necessary to first remove vapour and encourage the air gap baffle plate bolt of both sides, take out generator amature, put back to generator amature after maintenance, be then reinstalled bolt. Power generator air gap baffle plate is commonly installed the stud of hollow, during installation, first stud one is screwed in the bolt hole on air gap baffle plate, then fastens with nut in other end, and during dismounting, order is contrary.
Owing to electromotor vapour encourages the particular design of outer end cap in both sides, air-ducting ring, generator stator-rotator gap is little, and the embedded position of stator of air gap baffle plate is deeper, the available narrow space of operator, the removal tool that genuine man is equipped with is caused to there is certain hidden danger in using, when removing bolt, there is the problem that bolt falls down; Particularly after generator amature enters, when air gap baffle plate bolt is installed, require disposable time to dress up merit, it is not allow for bolt to drop, if and appearance is abnormal after installing, as not firm in bolt fastening, bolt falls in stator thorax by mistake, will have major safety risks, even will make the big heavy discount of generator maintenance effect, jeopardize unit safe operation in the future.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of convenient disassembly is provided, effect fastening is installed, prevents the high reliability power generator air gap baffle plate rapid dismounting apparatus of potential safety hazard.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of high reliability power generator air gap baffle plate rapid dismounting apparatus, for dismantling and install power generator air gap baffle plate, equipped with screw bolt and nut on described air gap baffle plate, described bolt is for being with female double end hollow bolt, it is characterised in that described device includes fixing bar and sleeve, described fixing bar one end is provided with external screw thread, the screw-internal thread fit of described external screw thread and bolt, described sleeve is provided with nut sleeve, and the inner wall shape of described nut sleeve coordinates with the outer wall of nut.
Described fixing bar is provided with multiple, and each fixing bar length is different.
Described sleeve entirety is hollow structure.
Described nut sleeve length is more than the length of nut thread.
This device also includes controlling bar, and described control bar is threadeded with fixing bar.
Described control bar is bent.
Described control bar entirety is hollow structure.
This device also includes ratchet spanner, described ratchet spanner and sleeve connection.
Compared with prior art, this utility model has the advantage that
(1) during assembling-disassembling bolt, being fixed the position of bolt by hand-held fixing bar, it is prevented that bolt arbitrarily rotates, thus improving dismounting speed, reducing electromotor final idle time.
(2) during dismounting, first passing through after nut unscrewed by nut sleeve, nut is still enclosed within bolt, and bolt is connected with fixing bar, and whole process screw bolt and nut will not fall down from air gap baffle plate; During installation as the same. Danger of dropping when therefore the device avoids dismounting.
(3) ratchet spanner of the bent and sleeve connection controlling bar conveniently adjusts degree of tightness, and installation tightness is good, and reliability is high.
(4) control bar and sleeve is hollow pipe, lightweight, easy to operate.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail. The present embodiment is carried out premised on technical solutions of the utility model, gives detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment
A kind of high reliability power generator air gap baffle plate rapid dismounting apparatus, is used for dismantling and installing power generator air gap baffle plate, and equipped with bolt 3 and nut 4 on air gap baffle plate, as shown in Figure 4, bolt 3 is for being with female double end hollow bolt.
As shown in figures 1-4, described device includes fixing bar 1 and sleeve 2, and fixing bar 1 one end is provided with external screw thread 11, external screw thread 11 and the screw-internal thread fit of bolt 3, fixes bar 1 and is provided with multiple, and each fixing bar 1 length is different, to adapt to different dismounting environment. Sleeve 2 is provided with nut sleeve 21, the inner wall shape of nut sleeve 21 coordinates with the outer wall of nut 4, for instance cross section of inboard wall can make hexagon, and nut sleeve 21 length is more than the length of nut 4 screw thread, therefore can fully wrapped around nut 4, reduce its danger dropped out from nut sleeve 21.
This device also includes controlling bar 5, controls bar 5 one end and is provided with female thread, and for being flexibly connected with the external screw thread of fixing bar 1 other end, controlling bar 5 other end is bent, facilitates hand-held.
This device also includes ratchet spanner, and ratchet spanner is connected with sleeve 2, for rotational sleeve 2.
When using attaching/detaching apparatus to install, first with controlling the bolt 3 that fixing bar 1 is screwed on air gap baffle plate by bar 5, then by nut 4 through fixing bar 1, again by sleeve 2 through fixing bar 1, adjusting angle makes nut sleeve 21 be enclosed within nut 4, finally by the ratchet spanner of sleeve 2 other end, rotate nut 4 and make it be fastened on bolt 3. Unloading process is contrary with installation process. Owing to bolt 3 is connected with fixing bar 1, nut sleeve 21 is enclosed within nut 4, it is to avoid the danger that bolt 3 and nut 4 drop from air gap baffle plate.The use controlling bar 5 and ratchet spanner improves dismounting speed block, reduces the generator outage time.
Overall in hollow structure owing to controlling bar 5 and sleeve 2, alleviate the weight of kit, operation is more flexible, reduces manufacturing cost.
