Description
Technical field
The invention belongs to nuclear reactor internal part assembly tooling technical field, particularly a kind of guide cylinder lifting device.
Background technology
Guide assembly is a particularly important part in pressure water reactor of nuclear reaction in-pile component, and its accuracy of manufacture requires
It is high.Guide assembly is the part of reactor upper-part in-reactor component, and guide cylinder is the guidance set of control rod insertion reactor core,
Its top by a number of there is perforate flange and square tube with C＆P systems same shape to form.Bottom is by some C
Shape pipe and double-hole tube are by together with flange welding.In in-pile component, bottom guide cylinder is arranged on upper core bearing assembly
Bottom, top guide cylinder are arranged on upper core bearing assembly top, IGA components lower section, and upper and lower two parts guide cylinder passes through upper
Hole is connected integral by spacer flanger in portion's core plate.
Need to be directed to cylinder when in-pile component assembles and repairs to remove from upper-part in-reactor component and be transferred to guide cylinder
On storage rack.There is instrument screen work component above guide cylinder（IGA components）, do not removing IGA components and upper core bearing assembly
In the case of, operating personnel cannot be introduced into reactor core and remove bottom guide cylinder.Therefore the dismounting man-hour length of guide assembly, process are multiple
Miscellaneous, easily generation is collided with and the situation of reactor core is fallen into fastener in disassembly process, and maintenance cost is high, has a strong impact on the duration.
Existing method typically uses upper and lower part guide cylinder lifting device when removing guide cylinder inside in-pile component,
Under, bottom guide cylinder lifting device can only individually lift by crane top guide assembly or bottom guide assembly, it is impossible to it is same
When lift by crane whole guide assembly., it is necessary to which staff enters progress inside in-pile component when being lifted using upper and lower part guide cylinder
Operation.And when removing bottom guide cylinder, it is necessary to which IGA components, top guide assembly and upper core bearing assembly is whole
After dismounting, bottom guide cylinder lifting device could be used to hang out bottom guide assembly.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of guide cylinder lifting device, safely and smoothly will entirely lead
Extracted out to cartridge module is disposably overall inside in-pile component.
The present invention adopts the technical scheme that：
A kind of guide cylinder lifting device, it is characterized in that, including outer sleeve, middle sleeve and interior circular shaft, the middle sleeve be placed on overcoat
In cylinder, the middle sleeve outer wall coordinates with outer sleeve inwall for gap, and the interior circular shaft is arranged on the centre in outer sleeve, described
The external diameter of interior circular shaft is less than the internal diameter of middle sleeve, and the interior circular shaft is relatively fixed with outer sleeve, and the top of the outer sleeve is set
Hanger, the lower section of the middle sleeve set at least one pair of handgrip by straight pin, in the setting pair of the side wall of outer sleeve and middle sleeve
The handgrip passage answered, the handgrip can outwardly open through the handgrip passage, and the interior circular shaft lower end is up big and down small
Taper, action bars is set in the upper end position of the middle sleeve, when the action bars drive middle sleeve moves up, the handgrip
Top outwardly opened by the effect of the taper of interior circular shaft lower end from handgrip passage, the action bars drives middle sleeve to moving down
When dynamic, the handgrip passage lower end of the outer sleeve is acted on handgrip outer wall, and handgrip is inwardly collapsed in middle sleeve.
Further, the upper end of the middle sleeve is less than the spacing of outer sleeve upper end one, and the spacing is when middle sleeve is upward
When being moved to handgrip opening, the upper end of the middle sleeve is located at below the upper end of outer sleeve.
Further, the handgrip be four, four tear open hand open when, arranged in cross.
Further, the action bars coordinates through the vertical slot on outer sleeve and interior circular shaft and middle sleeve, and the action bars exists
When being moved up and down in the vertical slot, the middle sleeve is driven to move up and down.
Further, pin-and-hole is opened up on the action bars, outer sleeve and interior circular shaft, action bars can consolidated by locking pin
Some position being scheduled on outer sleeve among the vertical slot.
Further, the interior circular shaft is fixed in outer sleeve by two locking pins, and two lock pin and arranged in cross, wear
The pin-and-hole crossed on outer sleeve and interior circular shaft fixes interior circular shaft.
Further, the locking lock is connected on outer sleeve by soft rope.
Further, the outer sleeve upper end connects the hanger by flange.
Further, graduation mark is set on the external diameter of the outer sleeve.
Further, sealed below the outer sleeve by bottom biock, the bottom biock is up big and down small pyramidal structure.
The beneficial effects of the invention are as follows：
（1）Convenient disassembly, can the remote-controlled operation on the operating platform on reactor core top；
（2）Can separately be hung with upper and lower part guide assembly, can also integral lifting guide assembly, simple to operate, space-consuming
It is small, it is practical；
（3）By setting rope, prevent part from dropping, can prevent that occurring locking pin in operation calls in heap core inner
Situation, the maintainability of guide assembly is improved, reduced because foreign matter falls into the possibility of reactor core；
（4）In the case where not removing IGA components and upper core bearing assembly, guide assembly is directly proposed or inserted, is carried
The maintainability of high guide assembly, maintenance time is reduced, reduce maintenance cost.
