The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, 2, this gas turbine rotor lifting appliance comprises a horizontal gird 1, horizontal gird 1 is provided with a motor 3, motor 3 is connected with an end of a screw rod 7 by a coupler, the other end of screw rod 7 is fixed on the supporting seat 8, screw rod 7 is provided with nut, and nut is with hanging piece 4 captive joints.7 rotations of motor 3 drive screw rods can drive hanging piece 4 and move around along the screw rod direction.The two ends of horizontal gird 1 also respectively are provided with a lifting catch gear 2.The below of horizontal gird 1 also is provided with two bracing frames 5.
Shown in Fig. 3,4, lifting catch gear 2 comprises a boatswain chair 20, form a lug boss 26 on the leading flank of boatswain chair, the trailing flank of boatswain chair is provided with a guide plate 21 and a baffle plate 25, guide plate 21 is relative with baffle plate 25, forms a guide groove 28 between guide plate 21 and the baffle plate 25, is provided with a jam plate 23 in the guide groove 28, jam plate 23 and boatswain chair 20 sliding block joints, jam plate 23 can slide up and down in guide groove 28.The middle part of a guide plate 21 and a control stalk 22 is hinged, and an end of control stalk 22 is connected with jam plate 23, and control stalk 22 is provided with an elongated slot, and jam plate 23 is inserted in this elongated slot by a bearing pin and is connected with control stalk 22.Control stalk 22 just forms a lever like this, can drive jam plate 23 by operation control stalk 22 and move up and down.Side back to guide plate 21 on the boatswain chair 20 is provided with a counterweight 24.The effect of counterweight 24 is when not using this lifting appliance at ordinary times, and the weight of balance guide plate 21 and control stalk 22 guarantees that boatswain chair does not tilt.Side lower end back to lug boss 26 on jam plate 23 forms an inclined-plane 27.
As shown in Figure 5, this lifting appliance is respectively offered a lifting groove 61 at air compressor end that fires machine rotor wheel disc 6 and turbine end earlier before lifting, and offers a depressed part that caves inward 62 on a side of lifting groove 61.The width of lifting groove 61 can change accordingly according to the position that the lifting groove is offered, can be greater than the width of turbine end lifting groove as the width of air compressor end lifting groove.The distances of two liftings between the catch gear 2 should equate with the distances between two lifting grooves, and each lift by crane the width of boatswain chair and jam plate addition on catch gear should be suitable with the width of corresponding lifting groove.
As shown in Figure 6, when lifting, at first boatswain chair 20 is inserted in the lifting groove, and make the lug boss 26 of boatswain chair 20 corresponding with depressed part 62 positions of lifting groove, then by control stalk 22 downward slip jam plates 23, jam plate 23 is inserted in the lifting groove, and the inclined-plane 27 on the jam plate 23 can make things convenient for jam plate 23 to be inserted in this lifting groove.Along with jam plate 23 to lower slider, the lug boss 26 of boatswain chair 20 inserts in the depressed part 62 of lifting groove, in the time of in jam plate 23 is stuck in the lifting groove fully, boatswain chair 20 can not be moved by locked again, at this moment can control stalk 22 afterbodys and guide plate 21 be connected together by chain, to prevent that jam plate 23 from shifting out the lifting groove, can effectively prevent from hoisting process, to occur the problem that boatswain chair breaks off relations like this.Can lift by crane after being installed in the lifting groove Deng the lifting catch gear on both sides.
Again as shown in Figure 2, to play hanging piece 4 during lifting is connected with driving, can make driving apply a little pulling force to one side rotor and leave bearing, can judge which limit is the lifting position whether overlap and be partial to rotor c.g., rotate by motor 3 drive screws 7 then, driven hanging piece 4 and moved to the appropriate location, the lifting position is overlapped with rotor c.g., as seen adopt this lifting appliance very convenient adjustment to lift by crane the position, reach the purpose of quick maintenance.This lifting appliance can be placed on two bracing frames 5 after lifting is finished and support.
In sum, this lifting appliance has following advantage:
(1) abandons mode, do not damage rotor in axle journal place lifting;
(2) the lifting position has firmly been fixed in the existence of jam plate, and the mode that rigidly fixes is safer than before;
(3) directly on rotor disk, lift by crane, need not to dismantle bearing, quicker;
(4) slide assemblies can slide along crossbeam, regulates the lifting center of gravity, is fit to the rotor lifting of different centers of gravity, and applicability is wide.
More than gas turbine rotor lifting appliance that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
