The specific embodiment
Like Fig. 1～shown in Figure 7, the present invention is a kind of aid of steam turbine welded disc turbine rotor upset, is used for cooperating with crane, to changing between the plumbness A (vertical state) of rotor and the accumbency state B (level).The upset aid of this particular design by upending frame 15 with stand up support two parts and constitute.Specifically introduce through this specific embodiment below:
Like Fig. 2, shown in 3, stand up support and comprise hold-down support 1, turning frame 2 and support column 3.
At first, do foundation special 13 in the place that rotor stands up, have screw on the base plate of hold-down support 1 in advance, according to its screw quantity and position, pre-embedded anchoring bolts in foundation special 13 is fixed on hold-down support 1 on the foundation special 13 again.
The side of hold-down support 1 is triangular in shape upwards, its top is hinged with turning frame 2 through rotating pin 5, and this hinged position makes that turning frame 2 is that rotating shaft is rotated to rotate pin 5 in perpendicular under the position of centre of gravity of counter-rotating frame 2.Profile and armature spindle head shapes are suitable in the frame of turning frame 2, are used for the lower end spindle nose of supporting rotor.In this specific embodiment, turning frame 2 is in four sides framework, the frame and is provided with V-arrangement support slot 4, in V-arrangement support slot 4, places sleeper, is used for the lower surface of support rotor.Simultaneously, can place the sleeper of suitable thickness, make one to stand up the rotor that support can be applicable to different-diameter, size according to the diameter of rotor lower surface support zone.
Support column 3 is arranged on the upset side of hold-down support 1; This support column 3 is dismountable moving members; When turning frame 2 turns to horizontal level; Support column 3 is moved to bottom, the fixed installation of turning frame 2, play the effect of supporting turning frame 2, make turning frame 2 be able to keep accumbency state B (level).
Like Fig. 4～shown in Figure 7, upending frame 15 is made up of frame body and clamping device.
The frame body is " door " type frame 6, and the top of being somebody's turn to do " door " type frame 6 is provided with lifting jockeys such as hanger or hanging axis, in this specific embodiment, adopts an electronic axis installing device 12 that is arranged on " door " type frame 6 top board sides, is connected with crane hook 13.
A hinged horizontally disposed workbench 9 between the bottom of " door " type frame 6, the relative two blocks of side plates that vertically are provided with; And the line between the articulated position on workbench 9 and 6 two blocks of side plates of " door " type frame is equivalent to the gyroaxis of workbench 9; Make it under the control of upset guider, can be around " door " type frame 6 bottom reversed, in 0-90 ° of scope, rotate.Workbench 9 is two sides structures, its upper surface be provided with workbench 9 upset guider, make it around " door " type frame 6 bottom reversed, the lower surface is provided with the clamping device of upending frame 15.
The guider that drives workbench 9 upsets comprises electronic feed screw nut 16, screw mandrel 7 and the electrical components thereof of mutual coupling.Screw mandrel 7 lower ends are hinged on the edge of workbench 9 upper surfaces; Feed screw nut 16 end and electrical components thereof is fixedly connected on this end face of " door " type frame 6 top boards, corresponding screw mandrel 7 guiding sides, and electrical components drives feed screw nut's 16 rotations, screw mandrel 7 is moved up and down.Simultaneously; On the rotor reverses direction; On two side plate end faces on the opposite side of " door " type frame 6 relative screw mandrels 7; The upset extreme position (90 ° of positions) of corresponding workbench 9 is provided with two highly identical limited blocks 8, and workbench 9 is played position-limiting action, and the maximum flip angle of control workbench 9 is 90 °.
The guider of these workbench 9 upsets can also be the guider of hydraulic cylinder or cylinder or other frame for movements; Such as the straight line hydraulic cylinder and the piston rod that adopt hydraulic pump control; Can directly control the speed of its upset through hydraulic pump, to reach effect safer, steady upset.
The clamping device of upending frame 15 comprises several jaws 10 and step switch 11 thereof, and jaw 10 is electrical control jaws 10, symmetrically, be mounted on the lower surface of workbench 9.Through step switch 11 controls, all jaw 10 corresponding its symmetrical centre, the synchronous work in opposite directions or opposite motion make jaw 10 whole respective rotor upper surfaces do the action that inwardly clamps or outwards open.
Concrete working method of the present invention is following, below by being example by the lifting process that accumbency state B transfers plumbness A to rotor, the original state of rotor is accumbency state B (state of horizontal positioned):
At first, will stand up support and be installed on the foundation special 13 through hold-down support 1, the electric rotation shaft device 12 at upending frame 15 tops is connected with lifting tool, in this specific embodiment, lifting tool is a crane hook 13.
Secondly, the turning frame that stands up support 2 is adjusted to level, with support column 3 support base and fixing; And load onto highly suitable sleeper in the V-arrangement support slot 4 in turning frame 2.Standing up support upset side distance the last period, place supporting apparatus, this supporting apparatus with stand up the rotor that support is used to lay level, the two end supports position of respective rotor respectively.In this specific embodiment, this supporting apparatus is a V-shaped rest, and this V-shaped rest center and the center of standing up support are on same axis, and V-shaped rest is confirmed according to the distance of lifting by crane between the two ends of rotor support zone with the distance of standing up between the support.
Once more, the lifting rotor with the lifting of rotor level, makes that an end of rotor is placed in the turning frame 2, end face contacts with the bottom of turning frame 2, and the other end is placed on the V-shaped rest; After noticing that rotor places, rotor axis should be level, and with the center of standing up support, V-shaped rest on same axis.
Then, load onto upending frame 15,, use the position, armature spindle end at the jaw 10 clamping V shape support places of upending frame 15 workbench 9 bottoms, and clamp through the control of step switch 11 at the rotor lifting end.
Again, take out the support column 3 of turning frame 2 bottoms, crane makes stably that slowly upending frame 15 moves upward, and when specifically lifting: rotor is hung in examination earlier, roughly becomes when lifting rotor and level on 10～15 ° the position to stop, and observes in this process to have or not abnormal conditions; After all are normal, proceed the lifting operation, turn to vertical state A until whole rotor.
