Description
Technical field
The present invention relates to a kind of combined support frames for Large Rotor core pulling.
Background technique
Large Rotor needs to take out rotor for after rotor and stator synchronous ascending certain altitude in core pulling
Out.Traditional method is that an equalizer bar suspender is hung using overhead traveling crane, and equalizer bar suspender both ends hang the jack of connection rotor, slowly forget about it
Chain raising rotor, while jack synchronization of jacking up stator is used, it is adopted after lifting altitude reaches requirement, then by integral support seat
It is hung to below rotor and is padded with truck crane, so that equalizer bar suspender carries out transposition lifting.Due to the gap between stator and rotor
Very little, and the mechanical strengths such as iron core, winding in stator are poor, if overhead traveling crane band-type brake or jack be slightly during raising for rotor
Failure, rotor will fall to and bring certain damage above stator to rotor and stator, and occurrence of equipment is caused to overhaul accident, influence
Plant maintenance quality improves overhaul of the equipments cost.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of combined support frame for Large Rotor core pulling,
This support frame overcomes the defect of traditional equipment maintenance mode, the collision of rotor and stator when effectively avoiding rotor core pulling operation, really
The repair quality of equipment is protected, overhaul of the equipments cost is reduced.
In order to solve the above technical problems, the present invention for Large Rotor core pulling combined support frame include pedestal,
Rocker bearing, link block, adjusting screw rod, guiding swivel nut, locking nut and several gate backing plates, the base top surface quadrangle are equipped with
Screw hole, the adjusting screw rod are twisted in the screw hole of the base top surface quadrangle, and the rocker bearing is located on the base top surface
Side, the link block are set to the rocker bearing two sides, and the guiding swivel nut is twisted in the adjusting screw rod and is fixed on described
The both ends of link block, the locking nut are twisted in the adjusting screw rod and between guiding swivel nut and the base top surface,
Several gate backing plates are laminated and are set between the base top surface and rocker bearing bottom surface.
Further, this support frame further includes arc nylon block, and the arc nylon block is set to the rocker bearing top surface simultaneously
And the arc matching of the two.
Further, several gate backing plates are the different steel plate of thickness.
Further, several gate backing plates include slim backing plate and thicker backing plate.
Further, the link block is that stiffener plate and being fully welded with the rocker bearing two sides is connect.
Combined support frame due to the present invention for Large Rotor core pulling uses above-mentioned technical proposal, i.e. this support frame
Base top surface quadrangle be equipped with screw hole, adjust screw rod twist in the screw hole of base top surface quadrangle, rocker bearing is located at base top surface
Top, link block are set to rocker bearing two sides, and guiding swivel nut twists in adjusting screw rod and is fixed on the both ends of link block, locking screw
Mother twist in adjust screw rod and be located at guiding swivel nut and base top surface between, several gate backing plates be laminated and be set to base top surface and
Between rocker bearing bottom surface.This support frame overcomes the defect of traditional equipment maintenance mode, effectively avoids turning when rotor core pulling operation
The collision of son and stator, it is ensured that the repair quality of equipment reduces overhaul of the equipments cost.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is the combination type support structure schematic diagram that the present invention is used for Large Rotor core pulling.
Specific embodiment
Embodiment is as shown in Figure 1, combined support frame of the present invention for Large Rotor core pulling includes pedestal 1, arc
Shape support 2, link block 3 adjust screw rod 4, guiding swivel nut 5, locking nut 6 and several gate backing plates 7,1 top surface four of pedestal
Angle is equipped with screw hole, and the adjusting screw rod 4 is twisted in the screw hole of the 1 top surface quadrangle of pedestal, and the rocker bearing 2 is located at the bottom
3 top faces of seat, the link block 3 are set to 2 two sides of rocker bearing, and the guiding swivel nut 5 is twisted in the adjusting screw rod 4 simultaneously
And the both ends of the link block 3 are fixed on, the locking nut 6 twists in the adjusting screw rod 4 and is located at the guiding swivel nut 5
Between 1 top surface of pedestal, several gate backing plates 7 are laminated and are set between 1 top surface of pedestal and 2 bottom surface of rocker bearing.
Preferably, this support frame further includes arc nylon block 8, and the arc nylon block 8 is set to 2 top surface of rocker bearing
And the arc of the two matches.The length of arc nylon block, width, which are subject to, is put into rocker bearing top surface, and it is direct to can avoid rotor
Collide the rocker bearing in steel construction.
Preferably, several gate backing plates 7 are the different steel plate of thickness.
Preferably, several gate backing plates 7 include slim backing plate and thicker backing plate.Slim backing plate Weight control is in a people
It can lift and be combined installation, thicker backing plate Weight control is combined installation and is advisable two people joint is liftable, pad surfaces
It is required that smooth, bright and clean, impulse- free robustness.
Preferably, the link block 3 is that stiffener plate and being fully welded with 2 two sides of rocker bearing is connect.To reinforce connection
The rigidity that block is connect with rocker bearing.
The present invention makes combined support frame according to rotor size, incite somebody to action this using the overhead traveling crane for hanging rotor before rotor lifting
Support frame is hung at below rotor and puts in place, then hangs a liter rotor using overhead traveling crane, and with rotor raising, adjustment adjusts silk in time
Bar adjusts screw rod and rotates in guiding swivel nut, so that guiding swivel nut is passed through link block and drives rocker bearing and rocker bearing top surface
Arc nylon block promoted and against to rotor bottom surface, while increasing gate cushion block between pedestal and arc bracket, to begin
It keeps rotor supports firm eventually, effectively prevent in rotor hoisting process, since overhead traveling crane band-type brake or jack fail, rotor and stator
Collision belt carrys out equipment damage.After rocker bearing height is adjusted in place, it can be kept away by the position of locking nut secured adjusted screw rod
Exempt from rocker bearing position to change.
The advantage that this combined support frame can be adjusted at any time compared with traditional integrated support with support member height, with
Meet live needs；Integrated support needs Special crane to be lifted in place, and using then available hang turns after this support frame
Sub- overhead traveling crane in advance hangs in support frame, and the height of manual adjustment arc bracket, arc bracket and bottom are used during rotor raising
It is superimposed gate cushion block between seat to provide effective support, reduces crane use, has saved overhaul of the equipments cost.
