Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the application is described in further detail.
As shown in figures 1 to 6, the embodiment of the present application provides a kind of main steam isolation valve hydraulic cylinder turning device, this main steam
Isolating valve hydraulic cylinder turning device is for keeping in repair the hydraulic cylinder of main steam isolation valve, and it includes bracing frame 1, rollover stand 2 and upset
Drive mechanism 3.Bracing frame 1 can use tower structure, and its effect is to support in main steam isolation valve hydraulic cylinder turning device
Other parts.Rollover stand 2 can be rotated by rotary shaft and be installed on bracing frame 1, and this rollover stand 2 is used for fixing with hydraulic cylinder 4,
It can use tower structure.Turnover driving mechanism 3 is installed on bracing frame 1, and this turnover driving mechanism 3 turns over for driving
Pivoted frame 2 overturns rotation in surface at hydraulic cylinder.Specifically, turnover driving mechanism 3 can use hydraulic motor, this hydraulic motor and
Oil circuit design need to have certain pressure maintaining effect, when power-off or when breaking down, is possible to prevent rollover stand 2 along with the work of center of gravity
With and uncontrollable rotation, then prevent accident.Certainly, this turnover driving mechanism 3 can also use the structures such as motor.
Need repairing the hydraulic cylinder 4 of main steam isolation valve time, hydraulic cylinder 4 is hoisted to above-mentioned main steam isolation valve hydraulic cylinder
The position at turning device place so that hydraulic cylinder 4 can fixing with rollover stand 2 be connected.Then pass through turnover driving mechanism 3 to carry
Dynamic rollover stand 2 rotates, until rollover stand 2 drives hydraulic cylinder 4 to turn to the position can keeped in repair hydraulic cylinder 4, is hereafter
Hydraulic cylinder 4 can be keeped in repair.After maintenance, rollover stand 2 is driven to rotate backward by turnover driving mechanism 3, until upset
Frame 2 drives hydraulic cylinder 4 to turn to initial position.
Owing to above-mentioned main steam isolation valve hydraulic cylinder turning device uses turnover driving mechanism 3 output switching activity driving force, because of
This need not manually implement turning operation, also would not produce the personal safety of operator and threaten.So, this main steam every
Safety when valve hydraulic cylinder turning device can improve the hydraulic cylinder 4 of upset main steam isolation valve.It addition, use this main steaming
After vapour isolating valve hydraulic cylinder turning device, at any time hydraulic cylinder 4 can be keeped in repair, improve the maintenance effect of hydraulic cylinder 4 with this
Rate.
In order to improve reliability when rollover stand 2 rotates and safety, above-mentioned main steam isolation valve hydraulic cylinder turning device
Also including locking mechanism 5, this locking mechanism 5 includes locking disk 50 and stop pin (not shown), and locking disk 50 is fixed on and props up
On support 1, locking disk 50 is offered lock hole, stop pin can through lock hole and with rollover stand 2 location fit.Specifically,
Can offer hole, location on rollover stand 2, stop pin can pass lock hole and hole, location, so that locking disk 50 and rollover stand 2
Between relative motion be restricted.
It is to be appreciated that the lock hole offered on above-mentioned locking disk 50 can be one, the most only realize in single position
Locking between rollover stand 2 and bracing frame 1.But, in order to be precisely controlled the position of rollover stand 2, can be by this lock hole
Being set at least two, each lock hole can be spaced along the rotation direction of rollover stand 2 and arrange.It is to say, at rollover stand 2
On rotation path, stop pin can be inserted in different lock holes, thus realize rollover stand 2 in multiple positions relative to propping up
The locking of support 1.It addition, the shape of above-mentioned lock hole, hole, location and stop pin can select flexibly, herein this is not limited
System.
During handling hydraulic cylinder 4, if directly handling appliance (such as driving) is connected with hydraulic cylinder 4, then
Structure comparison owing to being available on hydraulic cylinder 4 being connected with handling appliance is limited, and the handling causing hydraulic cylinder 4 is the most convenient.There is mirror
In this, aforementioned rollover stand 2 can include main frame 20 and support seat 21, and main frame 20 is installed on bracing frame 1, supports seat 21 and is used for
Fix with hydraulic cylinder 4, support and there is on seat 21 lifting portion, and support seat 21 can be fixed on main frame 20.Main frame 20 can
Use tower structure, support seat 21 and can include annular slab 210, connecting plate 211, fixing pipe 212, manual bolts 213 and hydraulic pressure
Cylinder fixed part 214.Annular slab 210 at least two, connecting plate 211 is fixedly connected with each annular slab 210, annular slab 210
Inner side can form hydraulic cylinder and accommodate space, and connecting plate 211 can be offered hole for hoist 211a.Fixing pipe 212 is for manually
Bolt 213 is fixed together with main frame 20, and hydraulic cylinder fixed part 214 is connected for fixing with hydraulic cylinder 4.
Therefore, after using said structure, after the hydraulic cylinder 4 of main steam isolation valve separates with valve body, seat will can be supported
21 are fixed together with hydraulic cylinder 4, then use handling appliance to be hoisted at main frame 20 present position by support seat 21.Then
Main frame 20 is secured together with supporting seat 21, then implements turning operation.Obviously, realize handling by support seat 21 to set
After connection between standby and hydraulic cylinder 4, the handling reliability of hydraulic cylinder 4 can be improved.
In a kind of embodiment, aforementioned bracing frame 1 can include base 10, crane 11 and lift drive mechanism 12, crane
11 are movably installed on base 10, and rollover stand 2 rotates and is installed on crane 11, and lift drive mechanism 12 is used for driving crane
11 so that crane 11 have away from or near the elevating movement direction of base 10.Wherein: base 10 and crane 11 are the most permissible
Using tower structure, base 10 is used for supporting other parts, and crane 11 is permissible under the effect of lift drive mechanism 12
Away from base 10 or near base 10, drive rollover stand 2 away from base 10 or near base 10 with this.Lift drive mechanism
12 can use threaded screw rod structure.This kind of structure can suitably change the rollover stand 2 height relative to base 10, with this in reality
While existing rollover stand 2 overturns smoothly, it is possible to reduce the height of rollover stand 2, in order to carry out maintenance operation.
After arranging aforementioned lifting structure, at the end of the lifting travel of lift drive mechanism 12, supporting seat 21 can
It is supported on maintenance basis 6.When maintenance basis 6 herein refers to maintenance fluid cylinder pressure 4, it is used for placing the platform supporting seat 21,
This maintenance basis 6 can be ground.Thus, after hydraulic cylinder 4 completes turning operation along with rollover stand 2, can be driven by lifting
Motivation structure 12 drives rollover stand 2 near maintenance basis 6, contacts until supporting seat 21 with maintenance basis 6.This technical scheme is permissible
