Description
Technical field
Guide rod used when being dismounted the present invention relates to hydrogen-cooled device and air cooler hydroecium.
Background technology
Hydrogen-cooled device, the air cooler of nuclear power generator can be lain in a horizontal plane on sleeper in maintenance, the meeting when dismounting upper tank
Aided in by its ring mounting hole, up lifting after suspension ring are installed, because horizontal positioned ring mounting hole afterwards is
In upper tank side, now lifting by crane lifting by suspension ring again can cause upper tank to lean forward, it is necessary to which multiple manually hold energetically
Hydroecium carrys out maintenance level, could the smoothly horizontal removal from bolt by upper tank.Labor intensity is high in such disassembly process,
Manually it is difficult to which hydroecium is lived in continual and steady support, upper tank is easily wiped with bolt and touched, and more due to taking personnel, and is applied
Power space is again limited, causes that operation difficulty is big, security is poor.In the disassembly process of lower header, due to no ring mounting hole,
Usually suspender belt is wound on water pipe flange to operate, it has the problem of same.Therefore the hydroecium dismounting of hydrogen-cooled device, air cooler
Need suitable aid.

Bar, the special guide rod of dismounting include shaft, horizontal handle are provided with the front end of shaft, in the rear end of shaft from front to back
The first limiting plate, the second limiting plate are disposed with, first limiting plate, the second limiting plate are located on shaft, and both
The gripping section spaced apart formed with this for laying suspender belt, the rear end end of the shaft have compared to the second limiting plate
One exposed extension, the extension section surface are provided with the helicitic texture matched with upper tank ring mounting hole.
Foregoing hydrogen-cooled device dismounts special guide rod with air cooler hydroecium, and the special guide rod of dismounting also includes and extension
The nut set of section matching.
Foregoing hydrogen-cooled device dismounts special guide rod with air cooler hydroecium, and anti-abrasion pad is provided with the outside of second limiting plate
Piece.
Implement technical scheme, at least with following beneficial effect：Using the special guide rod of dismounting come auxiliary water
The dismounting of room, the horizontal stable of hydroecium can be effectively kept, reduce artificial, reduction labor intensity, and it is safe.

Embodiment
In order to which technical characteristic, purpose and the effect of the present invention is more clearly understood, now compares accompanying drawing and describe in detail
The embodiment of the present invention.
A kind of hydrogen-cooled device dismounts special guide rod with air cooler hydroecium, and the special guide rod of dismounting includes shaft 1, in shaft 1
Front end horizontal handle 2 is installed, be disposed with the first limiting plate 3, the second limiting plate from front to back in the rear end of shaft 1
4, first limiting plate 3, the second limiting plate 4 are located on shaft 1（Equivalent to shaft from each limiting plate it is vertically interspersed and
Cross）, and both gripping sections 5 spaced apart formed with this for laying suspender belt 11, the rear end end of the shaft 1 is compared
There is an exposed extension 6 in the second limiting plate 4, the surface of extension 6 is provided with helicitic texture.
Special guide rod is dismounted to apply in the state of upper tank 8 as shown in figure 1, the upper tank of both hydrogen-cooled device and air cooler 8
Body has ring mounting hole 9, and mounting hole is female thread structure, and this is easy for using during machine overall package, and suspension ring are installed
Hole 9 is to be provided with polylith stiffener plate between two, two, so the periphery of ring mounting hole 9 can not be arranged suspender belt 11.Normally
Ring mounting hole 9 is the top in upper tank 8 during placement state, and needs to put hydrogen-cooled device or air device level when overhauling
Put, now ring mounting hole 9 is equivalent in the side of upper tank 8.
The dismounting of upper tank 8 typically is aided in using two guide rods, will there is helicitic texture on guide rod（With ring mounting hole
9 matchings）Extension 6 be screwed into ring mounting hole 9, suspender belt 11 is enclosed on to the position of gripping section 5, the both ends of gripping section 5 it is spacing
Plate can prevent suspender belt 11 from arbitrarily moving, it is ensured that utilize the stable lifting upper tank 8 of suspender belt 11.In the process using the lifting of suspender belt 11
In, one two guide rods of two hands while operation are typically only needed, because there is handle 2 at guide rod rear so being highly convenient for operating, and
It is distant with handle 2 and suspender belt 11 is located proximate to ring mounting hole 9, therefore the arm of force manually held is longer, utilize thick stick
One is easy to maintain moving horizontally for upper tank 8 rod principle, and when 8 run-off the straight of upper tank, manpower tilts according to upper tank 8
Direction is applied with lift or the strength pushed in shaft 1, and strength is transferred to the upper water of rear end with suspender belt 11 by shaft 1 for the strong point
Room 8, promote the stabilization in its keep level direction, smoothly to be removed at bolt 10.
The length of guide rod shaft 1 is one meter or so, is process by stainless steel, handle 2 is at the end of the front end of shaft 1
Portion, and the set location of the second limiting plate 4 is from handle 2 farther out, to form the longer arm of force, torque arm length preferably accounts for shaft 1
More than the 70% of length.
The lower header 12 of both hydrogen-cooled device and air cooler can be provided with water pipe flange 13, be dismounted to lower header 12
When, as shown in Fig. 2 the extension 6 of guide rod is interted in the through hole of water inlet pipe flange 13, in order that guide rod is connected more with flange
It is fixed, extension 6 is inserted through through hole and then nut set 14 is screwed on extension 6 to avoid guide rod arbitrarily from through hole
Middle disengaging.In disassembly process, the holding to the horizontal stable of lower header 12, the dismounting of the equivalent upper tank 8 of its operating principle, but this
When its suspender belt 11 be preferably enclosed at water pipe flange 13（As shown in Figure 2）, the periphery of water pipe flange 13, can be with without other obstruction structures
Be arranged suspender belt 11, the position of gripping section 5 be set in compared to by suspender belt 11, so can effectively reduce extension 6 and through hole this
The stress of one junction, avoid because the effect of long-term external force causes connection to deform；And water pipe flange 13 is a kind of rigid complete
Structure, its pressure-bearing property are stronger.
Typically it is provided with wear-resistant gasket 7 in the outside of the second limiting plate 4, wear-resistant gasket 7 is by the second limiting plate 4 and ring mounting hole
9 either water pipe flanges 13 are kept apart, and are reduced the rigidity friction between structure, are avoided equipment attrition.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various changes, combination and change.Within the spirit and principles of the invention, made
Any modification, equivalent substitution and improvements etc., should be included within scope of the presently claimed invention.
