Figure 1A ~ 1B is schematic diagram when dismounting of the parts on shaft in sealing chamber, owing to the dismounting space of the part 3 on sealing chamber 1 axis 2 is less, dismounting space is enclosed, existing parts on shaft dismantling device cannot be applied, it is longer that dismounting parts on shaft expends the time, during installation and removal, axle 2 and the trickle vibration of part 3, it is possible to make axle collide with part or part collides with sealing chamber, cause axle, sealing chamber and part deformation and damage.The parts on shaft that precision prescribed is higher is coordinated especially for some, during assembling, assembly precision is not easily controlled, assembly precision is caused to be unsatisfactory for requirement, reduction equipment and the service life of part, and way does not support buffering in an installation, is necessary for disposably installing putting in place, adds assembly difficulty.
At present, used in nuclear power station pump exists a lot of sealing chamber axis class formation, various part it is furnished with on axle, in nuclear power plant's maintenance stage, need to open and inspect power station pump, workload is bigger, and known dismantling device cannot be applied to the dismounting of the parts on shaft in sealing chamber, in substantial amounts of sealing chamber, dismounting can only be manually beaten in the dismounting of parts on shaft, has the most both wasted man-hour, the most easily injuring part and axle.Therefore, the attaching/detaching apparatus of parts on shaft in the general sealing chamber easy to use of a kind of structure is lacked.
Summary of the invention
It is an object of the invention to provide one parts on shaft attaching/detaching apparatus be applicable to sealing chamber; ensure assembly precision; improve assembling quality; the part that can also avoid dismounting coaxially collides with sealing chamber; play a protective role; the dismounting of various parts on sealing chamber axis can be met, it is not necessary to change dismantling device, save man-hour.
In order to realize object above, the present invention is achieved by the following technical solutions:
One is parts on shaft attaching/detaching apparatus be applicable to sealing chamber, is characterized in, comprises:
Support ring, it is erected on sealing chamber；
The guiding collar being arranged in support ring, it is nested with on axle；
Threaded rod, its one end is connected with part, and the other end sequentially passes through support ring, guiding collar, and is extended on the outside of guiding collar.
Described guiding collar centre is provided with a centre bore, and is distributed some to pilot hole with guiding collar centrosymmetry.
Described axle passes centre bore, and the centre bore concentric gap of described guiding collar coordinates.
Described threaded rod passes pilot hole, and several described pilot holes are suitable with the threaded rod of different size.
This attaching/detaching apparatus also comprises a pair hanger, and it is fixed in support ring.
The present invention compared with prior art, has the advantage that
(1) provide parts on shaft attaching/detaching apparatus in a kind of sealing chamber, be used for solving parts on shaft dismounting space in sealing chamber less, dismounting difficulty, it is easy to damage axle and the problem of part；
(2) the protection guiding collar of this attaching/detaching apparatus can be avoided colliding with other parts of surrounding because of shaft vibration in parts on shaft disassembly process in sealing chamber, and countershaft and part plays a protective role；
(3), in sealing chamber during parts on shaft assembling, this attaching/detaching apparatus plays guide effect by protection guiding collar, it is ensured that assembly precision, improves assembling quality；
(4) a series of pilot holes of this attaching/detaching apparatus design can be used for the dismounting of multiple parts on shaft, in disassembly process, it is not necessary to changes dismantling device, saves man-hour；
(5) for heavier part, this attaching/detaching apparatus is provided with hanger, uses the most dismantled and assembled parts on shaft of boom hoisting, simple in construction, it is easy to use；
(6) new thinking and breach are provided for the dismounting of part in other similar sealing chambers.
