Description
Technical field
The utility model is related to a kind of assembly and disassembly methods and dismantling device, particularly a kind of to be used for the dismounting of high-pressure self-sealing manhole
Specific purpose tool.
Background technology
The manhole for maintenance is provided with high-pressure bottle, conventional manhole structure has built-in self sealss people at present
Hole, four cyclization self sealss manholes, oval self sealss manhole, flange forced seal manhole etc..Come for four cyclization self sealss manholes
Say, its sealing structure is constituted by pining down ring, four cyclizations, sealed pressure pad and closure installed in manhole interior annular groove, in inspection
During repairing, ring dismounting will be pind down first, after then taking out four cyclizations and sealed pressure pad, closure could be taken out.For
For the high-pressure heater used in power plant or chemical enterprise, because the pressure in high-pressure heater is in more than 20MPa, four cyclizations
The thickness of closure in self sealss manhole is general in more than 100mm, and weight is in more than 150Kg, circular closure and manhole
Gap between cylinder bore is general in 2mm or so, and crane is generally required when taking out closure and coordinates progress, general during maintenance
One manhole of dismounting needs 4 people to cooperate 4 hours or so, could dismantle manhole, time-consuming, laborious, and in closure
When being separated with manhole, gap of the liquid between manhole and closure in high-pressure bottle is sprayed, and easily operating personnel are caused
Injury.
It is entitled " a kind of to be used for what oval self-sealing manhole cover was loaded and unloaded that China Intellectual Property Office 2013 year 03 month announces on the 13rd
The patent of invention of device ", application publication number is CN102962804A, and the device is the dress for assembling and disassembling oval self-sealing manhole cover
Put, because oval self-sealing manhole cover has point of major axis and short axle, after manhole cover is rotated by 90 ° during dismounting, allow the short of manhole cover
Axle can easily take out relative to the major axis of manhole.And for circular seal lid, due to closure and manhole inwall it
Between gap very little, and stroke of the closure in manhole is general in more than 100mm, small―gap suture, it is heavy weight under the conditions of,
How closure is safely removed, be to shorten one of key point of repair time.
The content of the invention
The purpose of this utility model be to provide it is a kind of can quickly, conveniently, safely be used for high-pressure self-sealing manhole dismount
Specific purpose tool.
To achieve the above object, the technical solution of the utility model is：It is a kind of to be used for the special of high-pressure self-sealing manhole dismounting
With instrument, including jack, the crossbeam for fixing jack and the column for support beam, it is characterised in that in one end of crossbeam
The alignment pin that the bolt hole with fixing four cyclizations on manhole circumference matches is fixed with, is fixed in the column upper end for support beam
There is sleeve, jack is arranged on crossbeam by assembly pulley, taking out bar one end has the spiral shell for being covered with Manhole Sealing Joints and installing hanging ring screw
The screw thread that pit matches, the suspension ring matched with jack are fixedly arranged in the middle of in taking-up bar.
Above-mentioned assembly pulley is by pulley, pulley bracket and is fixed on the suspension ring I of pulley bracket lower end and constitutes.
Above-mentioned column is door-shaped frame structure, and sleeve is fixedly arranged in the middle of in the upper beam of door-shaped frame structure, is pacified on sleeve
Equipped with fixing screws.
The side of alignment pin is fixed with location-plate on above-mentioned crossbeam.
Threaded end to the distance of suspension ring is not threaded end to 3-5 times of suspension ring distance to above-mentioned taking-up bar.
The technical program has the characteristics that：1st, it is simple in construction：Special dismantling device only has 3 rod members, an assembly pulley
Constituted with jack, structure is very simple, and Assembling is quick；2nd, it is easy to use：Needing to overhaul high-pressure bottle inside
When, after high-pressure self-sealing manhole peripheral component is removed, only need special dismantling device can be assembled for 10 minutes or so.Entirely
The dismounting of manhole only needs 2 people just detachably to finish for 1 hour or so, and due to having used assembly pulley in unloading process, can be square
Pulling out Manhole Sealing Joints lid level just, improves 4-8 times of manhole disassembly efficiency, can effectively reduce the repair time；3rd, column is used
Door-shaped frame structure, on the one hand improves the stability of column, on the other hand taking-up bar is bobbed and woven, be easy to
Adjust the gap between closure and manhole cylinder bore；4th, carry out disassembly process in, due to maintainer apart from manhole away from
During from farther out, can effectively prevent that closure from departing from manhole, in gap of the liquid between manhole and closure in high-pressure bottle
Spray, cause the generation of the injury phenomenon to operating personnel.
This special dismantling device is particularly suitable for use in the dismounting of interior sealing high-pressure bottle manhole.
