Abstract
Thread-locking ring dismantling spanner and its application method are related to the disassembly of thread-locking ring in pressure vessel maintenance, overcome prior art defect.Its structure one end is that the arc plate other end is long handle, and 3 holes are provided on arc plate, are fitted like a glove with thread-locking ring bolt hole；Long handle tail opens a circular hole；The arc plate part of dismantling spanner and shaft portion are rounding off.Application method: (1) dismantling spanner is fixed on the 90 ° of left-right positions of thread-locking ring (2) with bolt and nut；The long handle tail circular hole of dismantling spanner (1) penetrates wirerope, and wirerope is hung on crane；(1) crane slowly lifts by crane dismantling spanner, after being slowly rotated by 90 ° dismantling spanner counterclockwise, thread-locking ring can be realized and be (2) rotated by 90 ° counterclockwise；Being repeated several times, which can be realized, screws out several buttons for thread-locking ring.The invention saves time and labor, can prevent the problems such as bolt is because of the excessive generation unhook of stress, bolt fracture and thread biting locking.Structure is simple, easy to make, easy to install, easy to operate, quick detachable.
Description
Technical field
The invention belongs to the disassemblies of thread-locking ring in pressure vessel manufacturing field, more particularly to maintenance.
Background technique
The tube side of screw-lock ring type of heat exchangers, which seals, uses thread seal, outside bobbin carriage cylinder internal screw thread and thread-locking ring
Screw thread cooperates, and realizes the entire closed state of equipment.Since equipment is chronically in high temperature and high pressure condition, run in equipment
After a cycle, the screw thread of equipment thread-locking ring and equipment barrel often occurs bonding serious situation, in overhaul of the equipments such as
The former buttons what loosens thread-locking ring are a very difficult links.Current loosening disassembly mode is in thread-locking ring
Handle fills a stay bolt on the threaded hole in orientation of 90 ° or so of outer ring；Then stay bolt is lifted by crane by crane or overhead traveling crane to drive spiral shell
The rotation of line retaining ring.The problems such as unhook, bolt fracture and thread biting locking, easily occurs for this method, makes troubles to maintenance, arduously
Time-consuming causes economic loss.
Summary of the invention
Target of the present invention is design, manufactures a kind of dismantling spanner, can overcome prior art defect.
Technical solution is:
Thread-locking ring dismantling spanner, structure one end are that the arc plate other end is long handle, are provided with 3 on the arc plate and compare screw thread
The hole of the big 2mm of retaining ring hold-down bolt diameter, the arrangement in hole and the arrangement of thread-locking ring bolt hole fit like a glove；The length
Handle tail opens a circular hole, can penetrate wirerope；The arc plate part of dismantling spanner and shaft portion are rounding off.
The application method of thread-locking ring dismantling spanner:
1. equipment bobbin carriage cylinder 3 sets horizontal direction, make thread-locking ring 2 in vertical direction, by the compression of 2 outer ring of thread-locking ring
Bolt is dismantled completely；
2. dismantling spanner 1 to be fixed on to 90 ° of left-right positions of thread-locking ring 2 with bolt and nut；
3. the long handle tail circular hole of dismantling spanner 1 penetrates wirerope, wirerope is hung on crane；
4. crane slowly lifts by crane dismantling spanner 1, lifting force is acted on the bolt of fixed dismantling spanner, slowly by dismantling spanner
After being rotated by 90 ° counterclockwise, thread-locking ring 2 can be realized and be rotated by 90 ° counterclockwise；
5. removing dismantling spanner, repetition is fixed on 90 ° of left-right positions of thread-locking ring, repeats rotation several times, can be realized by
Thread-locking ring screws out several buttons.
Compared with the prior art, the present invention has the following advantages:
1, the quantity of stressed bolt is increased, while increasing stress radius, reduces active force when disassembly, it being capable of time saving province
The loosening of power and the former button screw threads for screwing out thread-locking ring, can prevent bolt because excessive the generations unhook of stress, bolt fracture and
The problems such as thread biting locking.
2, structure is simple, easy to make, easy to install, easy to operate, quick detachable.
Detailed description of the invention
Fig. 1 is thread-locking ring dismantling spanner structural schematic diagram；
Fig. 2 is thread-locking ring dismantling spanner working principle diagram；
Wherein: 1-dismantling spanner, 2-thread-locking rings, 3-equipment bobbin carriage cylinders.
Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.
Thread-locking ring dismantling spanner as shown in Figure 1:, structure one end are that the arc plate other end is long handle, the arc plate
On be provided with 3 holes 2mm bigger than thread-locking ring hold-down bolt diameter, the arrangement in hole and arranging for thread-locking ring bolt hole
It is complete to coincide；The long handle tail opens a circular hole, can penetrate wirerope wherein；The arc plate part of dismantling spanner and long shank
It is divided into rounding off, reduces stress and concentrate.
It is as shown in Figure 2: the application method of thread-locking ring dismantling spanner:
1. equipment bobbin carriage cylinder 3 sets horizontal direction, make thread-locking ring 2 in vertical direction, by the compression of 2 outer ring of thread-locking ring
Bolt is dismantled completely；
2. dismantling spanner 1 to be fixed on to 90 ° of left-right positions of thread-locking ring 2 with bolt and nut；
3. the circular hole of the long handle tail of dismantling spanner 1 penetrates wirerope, wirerope is hung on crane；
4. crane slowly lifts by crane dismantling spanner, lifting force is acted on the bolt of fixed dismantling spanner, slowly by dismantling spanner
After being rotated by 90 ° counterclockwise, thread-locking ring can be realized and be rotated by 90 ° counterclockwise；
5. removing dismantling spanner, repetition is fixed on 90 ° of left-right positions of thread-locking ring, repeats rotation several times, can be realized by
Thread-locking ring screws out several buttons.
The dismantling spanner of different size can be manufactured, to be applicable in the thread-locking ring of different size.
