Description
Technical field
The utility model relates to the dismounting of the nuclear island reactor pressure vessel protection system in nuclear power station maintenance process, particularly relates to a kind of special purpose device for removing the acceleration transducer be arranged on top cover.
Background technology
The top cover of nuclear island of nuclear power station reactor pressure vessel and tank body, when assembling, can arrange installation acceleration transducer in top cover of reactor pressure vessel bolt upper center circular hole.When overhauling nuclear island of nuclear power station reactor pressure vessel protection system; the acceleration transducer be arranged on top cover of reactor pressure vessel bolt is needed to carry out dismounting; maintainer is when removing acceleration transducer; need first to utilize the interior hexagonal on interior hexagonal removal sensor A-frame; use fork spanner removal sensor base again, degree of will speed up sensor is removed together with cable.But cover owing to there being heat-insulation layer above top cover of reactor pressure vessel, heat-insulation layer range sensor body has certain altitude, maintainer cannot stretch into pressure vessels top cover bolt and carry out disassemble and assemble work from the space of heat-insulation layer, first must remove the disassemble and assemble work that this heat-insulation layer just can carry out acceleration transducer.But make in demolishing process, to have instrument to fall in this way, injure personnel's equivalent risk by a crashing object, and due to operating space narrow and small, maintainer cannot observe device interior situation, accurately can not locate the fixing point of sensor, and the sensor after removing is easy to crash in heat preservation sandwich layer and causes damage, dismounting difficulty, so that extend the duration, delays repair schedule.
Utility model content
For the dismounting brought when solving prior art dismounting acceleration transducer is difficult, long in time limit and the problem of easy damaged, the utility model proposes a kind of acceleration transducer dismounting device, this acceleration transducer dismounting device comprises sleeve and handle; Described sleeve is that one end is closed, inside can the tubular structure of sheathed acceleration transducer, and the blind end of described sleeve is provided with handle mounting head; Described handle is provided with the handle mounting groove matched with described handle mounting head, described handle arrangement mounting groove is set in described handle mounting head, and described handle is vertical with described sleeve arranges.
In use, described handle mounting groove is set in described handle mounting head, the sleeve part of the utility model acceleration transducer dismounting device is stretched into from the space of pressure vessels top cover acceleration transducer probe top heat-insulation layer, by jacket casing on acceleration transducer, hand-held handle screws, handle strip moving sleeve is around the center axis thereof of acceleration transducer treating dismounting, thus degree of will speed up sensor and bottom mount pad and cable are together pulled down, after maintainer completes dismounting, degree of will speed up sensor takes out.
Use the utility model acceleration transducer dismounting device, without the need to removing heat-insulation layer in advance, simple to operate, operation reduces, and improves overhaul efficiency, shortens maintenance duration, and acceleration transducer and bottom mount pad are together pulled down, parts after dismounting are stably placed in triangular supports, are convenient to staff and take out, avoid and remove post-acceleration sensor and fall and cause damaging the loss brought.
Preferably, described acceleration transducer dismounting device also comprises one and lengthens cylinder, and one end of described lengthening cylinder is provided with projection, and the other end is provided with groove, and described projection coordinates with described handle mounting groove, and described groove coordinates with described handle mounting head.Described lengthening cylinder is arranged between described handle and described sleeve, make maintainer when using the utility model device without the need to finding suitable turning position in heat-insulation layer space, directly operate above heat-insulation layer, the scope that screws increases, and reduces maintenance difficulty.
Preferably, described handle mounting head is fastening by set bolt after loading described handle mounting groove.Ensure that the bonding strength between handle mounting head and handle mounting groove, ensure that carrying out smoothly of service work.
Use the utility model acceleration transducer dismounting device, simple to operate, overhaul efficiency is high, and maintenance duration is short, and the parts not easy damaged after removing, avoid unnecessary economic loss.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model acceleration transducer dismounting device.
Detailed description of the invention
As shown in Figure 1, a kind of acceleration transducer dismounting special purpose device comprises sleeve 1, lengthens cylinder 2 and handle 3; Sleeve 1 for one end close, inside can the tubular structure of sheathed acceleration transducer, the blind end of sleeve 1 is provided with handle mounting head 11; Lengthen one end of cylinder 2 and be provided with groove 21, the other end is provided with protruding 22, and groove 21 coordinates with handle mounting head 11, and shape, the size of projection 22 and handle mounting head 11 are identical; Handle 3 is provided with the handle mounting groove 31 matched with handle mounting head 11, protruding 22 also can coordinate with handle mounting groove 31; Lengthen the groove 21 of cylinder 2 nested with the handle mounting head 11 of sleeve 1, protruding 22 and handle mounting groove 31 nested arrangements of handle 3, and handle 3 and sleeve 1 are vertical with lengthening cylinder 2 arranges.
Preferably, handle mounting head 11 is fastening by set bolt 4 after loading groove 21, fastening by set bolt 4 after protruding 22 loading handle mounting grooves.Ensure that the bonding strength between each connecting portion, ensure that carrying out smoothly of service work.
In use, the top cover of cable from pressure vessel is removed, again the sleeve 1 of the utility model acceleration transducer dismounting device is stretched in the cable entry port of pressure vessels top cover from the space of heat-insulation layer, sleeve 1 is enclosed within acceleration transducer, hand-held handle 3 screws, handle 3 is with moving sleeve 1 and lengthen cylinder 2 around the center axis thereof of acceleration transducer treating dismounting, thus degree of will speed up sensor and bottom mount pad are together pulled down, after maintainer completes dismounting, degree of will speed up sensor takes out.
Use the utility model acceleration transducer dismounting device, without the need to removing heat-insulation layer in advance, simple to operate, operation reduces, and improves overhaul efficiency, shortens maintenance duration, and acceleration transducer and bottom mount pad are together pulled down, parts after dismounting are stably placed in triangular supports, are convenient to staff and take out, avoid and remove post-acceleration sensor and fall and cause damaging the loss brought.
