The beneficial effects are as follows: the special tool is used for replacing manual operation of people, so that the online replacement of the sealing air bag can be realized, the replacement time is saved, the labor intensity of workers is reduced, the utilization efficiency of equipment is improved, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of disassemblerassembler of technical field of metallurgical equipment more particularly to a kind of 175T-RH seal section gas
Capsule replaces specific purpose tool and replacing options.
Background technique
Certain steel-making three work area 175T-RH of head factory is vacuum-treated top gun seal section and is mounted on above vacuum chamber furnace, in vacuum drying oven
For portion's temperature up to 1200 DEG C or so, seal section intermediate channel is the access way of top gun, internal because requiring during vacuum system production
For vacuum negative pressure condition, therefore sealing is realized by pressure bladder between top gun and seal section during producing.Pressure bladder is easy
Part is damaged, after a period of use because the failure of the reasons such as abrasion, aging, breakage needs to change new product, and the frequency replaced is higher.Sealing
Air bag replace when, top gun need to be carried away to seal section, at this time the high temperature heat wave of internal vacuum chamber can be by seal section inner passage outside
Stream is replaced so that at air bag in the high temperature environment, setter arm can not protrude into more ventilation bag inside seal section to pressure bladder
Bring difficulty.Currently, the replacing options taken are that online vacuum chamber is first moved on to standby position baking by technologist, heat source is removed
Afterwards, more ventilation bag operation can be started after temperature reduction.There is following defects:
1) large labor intensity is moved back to again after needing to move on to online vacuum chamber standby position waiting operation, cumbersome；
2) there is no special equipment, when replacement, manually put in seal section hand by operator and construct, have calcination dangerous；
3) replacing construction is long, in addition vacuum chamber is moved back to online position altogether again and needs 30-40 points from standby position waiting is displaced to online
Clock；
4) production efficiency is low, and due to pressure bladder category vulnerable part, high frequency of replacement, therefore, replacement pressure bladder are occupied
Very big production time.
Summary of the invention
The present invention provides a kind of 175T-RH seal section air bag replacement specific purpose tool and replacing options, with specific purpose tool generation
For people's handwork, it can be achieved that the online replacement of pressure bladder, saves replacing construction, labor intensity of workers is reduced, equipment is improved
Utilization efficiency improves production efficiency.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
A kind of 175T-RH seal section air bag replacement specific purpose tool, including fixed handle, left flexible handle, pin shaft, left side folder
Tight plate, right flexible handle, right side clamping plate, which is characterized in that the left flexible handle, right flexible handle pass through respectively pin shaft with
Fixed handle is hinged, and left side clamping plate, right side clamping plate are separately positioned on the end of left flexible handle, right flexible handle.
The left flexible handle, right flexible handle are two link mechanism of " < " shape, symmetrically hinged along fixed handle middle line
Setting, between left flexible handle and fixed handle and between right flexible handle and fixed handle respectively can relative rotation, phase
5 °~10 ° are designed as to rotation angle a.
The left side clamping plate, right side clamping plate end be respectively equipped with convex-concave reticulate pattern.
A kind of 175T-RH seal section air bag replacing options, replacement process the following steps are included:
1) air sac press-cover bolt is unclamped, air sac press-cover is unloaded；
2) the invention specific purpose tool is protruded into pressure bladder, while both hands hold fixed handle, its in addition to thumb
Four finger grippings tightly left flexible handle, right flexible handle are remaininged, until left side clamping plate, right side clamping plate distinguish pinch seal air bag；
3) both hands firmly lift upwards can be taken off old pressure bladder；
4) which similarly, is protruded into preprepared novel sealing air bag, both hands hold fixed handle
Meanwhile four finger gripping of remaining in addition to thumb tightly left flexible handle, right flexible handle, until left side clamping plate, right side clamping plate
Pinch seal air bag respectively；
5) it is directed at pressure bladder notch, firmly pressure can be packed into new pressure bladder to both hands downwards；
6) air sac press-cover is loaded onto, replacement can be completed in locking air sac press-cover bolt.
Compared with prior art, the beneficial effects of the present invention are:
1) labor intensity is small, and when replacement does not need to move on to online vacuum chamber after standby position waits operation and be moved back to again,
Working procedure is reduced, labor intensity of workers is reduced；
2) special equipment substitutes manual operation, when replacement, need not put in seal section hand by operator and construct, not burn
It burns dangerous；
3) replacing construction is short, it is only necessary to 10 minutes or so；
4) upkeep operation efficiency is improved, production efficiency is also just improved.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: on the left of the left flexible handle 3- pin shaft 4- of 1- fixed handle 2- on the right side of the right flexible handle 6- of clamping plate 5-
Clamping plate 7- pressure bladder 8- air bag seat
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing:
As shown in Figure 1, a kind of 175T-RH seal section air bag of the present invention replaces specific purpose tool, including fixed handle
1, left flexible handle 2, pin shaft 3, left side clamping plate 4, right flexible handle 5, right side clamping plate 6, the left flexible handle 2, right work
Fixed handle 5 is hinged by pin shaft 3 and fixed handle 1 respectively, and left side clamping plate 4, right side clamping plate 6 are separately positioned on left movable hand
The end of handle 2, right flexible handle 5.
The left flexible handle 2, right flexible handle 5 are two link mechanism of " < " shape, along the middle line pair of fixed handle 1
Claim hinged setting, it respectively can be opposite between left flexible handle 2 and fixed handle 1 and between right flexible handle 5 and fixed handle 1
Rotation, relative rotation angle a are designed as 5 °~10 °, it is ensured that clamping does not damage pressure bladder 7.
