Description
Technical Field
The utility model belongs to nuclear power station mechanical assembly field, concretely relates to nuclear power station gate valve flashboard lifting device.
Background
The nuclear power station has used the gate valve in a large number, and its flashboard frame top is connected for T type groove with the valve rod junction, when the gate valve maintenance, need take out flashboard frame from the valve intracavity, uses one to add the lug with flashboard frame top T type groove size similar T type piece to hoist and mount usually, and the hoist and mount in-process is owing to do not have T type piece and do not have limiting displacement, and flashboard frame slippage can cause industrial safety accident or damage flashboard frame and flashboard.
Disclosure of Invention
An object of the utility model is to provide a nuclear power station gate valve flashboard lifting device, this instrument have avoided the landing risk of flashboard frame hoist and mount in-process, prevent that flashboard frame from droing and hindering people or damage equipment.
Realize the utility model discloses the technical scheme of purpose: the utility model provides a nuclear power station gate valve flashboard lifting device, this instrument includes limiting plate, bottom plate and pivot, and the bottom plate both sides are equipped with the limiting plate, rotate through the pivot between bottom plate and the limiting plate and are connected.
And two sides of the bottom plate are respectively provided with a limiting plate.
The two sides of the bottom plate are respectively embedded in one side of one limiting plate, and the two sides of the bottom plate are respectively connected with the two limiting plates through a rotating shaft.
The convex blocks on the two sides of the bottom plate are respectively embedded in the grooves on one side of one limiting plate.
And a hinge is respectively arranged between the two limiting plates and the bottom plate.
The hinge, the limiting plate and the bottom plate are fixedly connected through screws.
And the other side of each limiting plate is provided with a lifting lug.
The utility model has the advantages of: the hoisting tool of the utility model has simple structure and convenient use; the gate plate frame is limited by the structure of the hinge, so that the risk that the gate plate frame slides down when the gate plate frame is hoisted can be effectively solved, and the gate plate frame is prevented from falling off to hurt people or damage equipment; this instrument can be used to this flashboard frame hoist and mount that has T type groove, and flashboard frame landing risk when effectively solving flashboard frame hoist and mount prevents that flashboard frame from droing and hindering the people or damaging equipment, has better popularization and application prospect.
