Description
Technical field
The present invention relates to a kind of change of current field valve module hoisting fixtures.
Background technique
For the requirement for meeting HVDC transmission system high voltage, high current, converter valve, mixing in high voltage direct current converter field
The equipment such as formula high voltage DC breaker are made of the power electronic devices series, parallel of substantial amounts；For convenience of assembling and overhaul,
Generally use modularized design, i.e., by certain amount, function is identical, the consistent power electronic devices of model constitute one it is independent
Functional unit --- valve module, then converter valve, hybrid high voltage DC breaker are constituted by multiple valve module units.For valve mould
The lifting work of block is still realized at present using traditional hanging belt Hoisting Program, in hoisting process, it is easy to valve occur
In module centre-of gravity shift, valve module situations such as device stress damage deformation.
Summary of the invention
The object of the present invention is to provide a kind of change of current field valve module hoisting fixtures, make for solving the lifting of change of current field valve module
The problem of device stress damage deformation in valve module is easy to appear when industry.
To achieve the above object, change of current field valve module hoisting fixture of the present invention uses following technical scheme: this is changed
Flow field valve module hoisting fixture includes two lifting beams of parallel interval setting, and interval is equipped at least two below each lifting beam
A lifting leg, the height for lifting leg are higher than the height of all devices in the valve module of quasi- lifting, are equipped with terminal pad below lifting leg,
Terminal pad is equipped with for the locking hole with the connecting hole cooperation carried on valve module, and two lifting beams are connected to by bridging beam
Together, bridge joint beam is equipped with the mounting hole for installing hanging ring.
The beneficial effects of the present invention are: by the change of current field, valve module hoisting fixture is hung to quasi- hanging valve mould when lifting valve module
At block, the change of current field valve module hoisting fixture is fixed with quasi- hanging valve module by terminal pad, because the change of current field valve mould is fast
The height of the lifting leg of hoisting fixture is higher than the height of all devices in valve module, so change of current field valve module slinger pretends
When in increasing a shield above valve module, and the change of current field valve module hoisting fixture is rigid structure, and change of current field
The hanging ring installation point of valve module hoisting fixture is located at the top of the change of current field valve module hoisting fixture, so lifting in hoisting process
Band will not be touched with the device on valve module, and the device in valve module can be damaged to avoid hanging belt.
Further, the position of bridge joint beam installation is corresponding with the installation lifting position of leg below lifting beam.
Beneficial effect improved in this way is: because the terminal pad below lifting leg is connect with quasi- hanging valve module, lifting
The link position stress of leg and lifting beam is larger, here by the installation of bridge joint beam, can become to avoid lifting beam because stress is excessive
Shape.
Further, bridging the mounting hole on beam has multiple, all mounting holes edge bridge joint beam length direction arranged for interval.
Beneficial effect improved in this way is: when on-site hoisting valve module, can change in conjunction with the position of centre of gravity of valve module with this
The position of centre of gravity of flow field valve module hoisting fixture can guarantee that valve module is lifting to select different mounting holes to install hanging ring
Stationarity in the process.
Further, bridge joint beam and lifting beam releasable connection.
Beneficial effect improved in this way is: the change of current field valve module hoisting fixture when not in use, can will bridge joint beam tear open
Get off, all bridge joint beams set placement, and all lifting beams for being equipped with lifting leg set placement, can save parking space.
Further, bridge joint beam and lifting beam pass through bolt releasable connection.
Beneficial effect improved in this way is: be bolted it is easy for installation, and can increase pretightning force with prevent bridge joint beam
It is loosened with lifting beam.
Further, bridge beam section be it is I-shaped, for install hanging ring mounting hole be located at bridge joint beam top one
Side.
Beneficial effect improved in this way is: the bridge joint beam bending resistance of I-shaped cross-section is strong, can be improved the change of current field valve
The structural strength of module hoisting tooling, and facilitate the connection of bridge joint beam and lifting beam.
