Description
Technical field
Present invention relates particularly to a kind of attaching/detaching apparatus of the vertical straight-arm flanged joint equipment of simplicity.
Background technology
In industrial production, has and removable equipment is much realized by flanged joint.In connected two-part assembly and disassembly
Or in disassembly process, lifting equipment (driving, truck crane, jack etc.) need to be used.Especially during turnaround of unit, due to by road
The limitation on road, the height of device, space etc., at device scene, dismounting is extremely troublesome.
Invention content
It needs to use lifting equipment when it is an object of the invention to solve current flanged joint equipment dismounting, there are costs
Defect high, dismounting is time-consuming and laborious, inconvenient, provides a kind of attaching/detaching apparatus of the vertical straight-arm flanged joint equipment of simplicity,
Dismounting no longer need lifting equipment and it is time saving and energy saving save money.
The present invention is achieved by the following technical solution:
I.e. a kind of attaching/detaching apparatus of the vertical straight-arm flanged joint equipment of simplicity, it is characterised in that lifted including turbine lead screw
Device, the elevating screw of Screw of Worm Gear lifter are straight-bar, are set with 3 axle sleeves on elevating screw, turbine lead screw lifter and 3
Connecting plate is equipped on the inside of axle sleeve.
Locking nut is equipped on the elevating endless screw of the present invention at outermost axle sleeve.Enhance safety.
A scheme as the present invention：The Screw of Worm Gear lifter of the present invention and its close axle sleeve are connected as one,
Remaining two axle sleeves are connected as one.The quantity of axle sleeve is reduced, assembly is easier.
The turbine lead screw lifter of the present invention is combined by worm and gear, and worm gear internal thread does axial fortune with lead screw cooperation
It is dynamic, it is mainly used to rotary motion being transformed to linear motion or linear motion is transformed to rotary motion to complete the liter of object
Drop, push-and-pull etc..The maximum feature of Worm gear feed screw lifter is exactly with self-locking function, when the lead angle of worm screw is less than the engagement gear teeth
Between equivalent friction angle when, mechanism has self-locking performance, it can be achieved that reverse self-locking, i.e., can only drive worm gear by worm screw, and cannot be by
Worm gear drives worm screw.Self-locking function can be very good protection equipment safety operating.
The present invention is consolidated by connecting rod respectively by worm screw lifter and close to the first axle sleeve of worm screw lifter
It is scheduled on the first cylinder (shell) of flange side, second, third remaining axle sleeve is fixed by the connecting rod another in flange respectively
On the second cylinder (shell) of side, the bolt on flange is unclamped, two cylinder (shell) separation are made by worm screw lifter,
Touching the second cylinder (shell) can rotate relative to the first cylinder (shell), and dismounting is not necessarily to lifting equipment.
When flanged joint equipment allows welding, connecting plate may be used the mode directly welded and be fixed in equipment；
When flanged joint equipment does not allow welding, can clip or portal frame be set in device external, connecting plate is welded
It is connected on clip or portal frame.
Vertical flanged joint equipment of the present invention, including but not limited to heat-exchange apparatus are (heater, cooler, cold
Condenser, steam generator, waste heat boiler, heat exchanger type reactor etc.), open type reactor etc..
The present invention has the advantages that simple in structure, at low cost, flexible and convenient to use, efficient.Using the present invention, without making
With lifting equipment, dismounting cost is substantially reduced；The present invention it is small, limited by road, the height of device, space it is small, in device
Scene dismounting is extremely convenient, can greatly improve disassembly efficiency.
