Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As shown in the figure: tray 22 on frame 6, and at least two group turning rolls 1 are installed on pallet 22, on each turning rolls 1 roller shaft are installed, and roller 2 is installed on each roller shaft.During use, the axle 24 of turbine rotor rests on the roller 2, roller 2 can carry out forward and reverse rotation by maintainer's requirement, and the drive turbine rotor rotates together, the easy access personnel operation, in frame 6 and 22 on pallet rolling element 26 is arranged, when needs are adjusted the horizontal level of pallet, pallet 22 is slided on rolling element 26.Used rolling element 26 can be roller or ball.
Mounting support base plate 10 below frame 6, between bearing plate 10 and frame 6, elevating mechanism is arranged, worm reducer 7 is arranged in the elevating mechanism, the input of worm reducer 7 is connected with lifting wheel 20 on being installed on elevating mechanism, the output of worm reducer 7 is connected with frame 6, when needs are adjusted the height of frame 6, rotates lifting wheel 20, drive elevating screw by worm reducer 7 and rotate, make the nut that is installed on the frame 6 drive frame 6 and move up and down.Because turbine rotor is relatively heavier, therefore must utilize bearing plate 10 to support.
Two groups of turning rolls 1 flexibly connect with axle 23 and pallet 22 respectively, and on 1 axle 23 therein drive is installed, motor and decelerator 13 are installed in middle part in frame 6, the drive 14 of decelerator 13 utilizes driving-belt 12 to be connected with the drive of axle on 23, and another drive on spools 23 is connected with the drive on being installed on roller shaft.Make wherein 1 consist of active roller.When maintenance, this active roller can rotate under the drive of motor and decelerator 13, drives turbine rotor again and rotates, and another group then becomes passive roller.Because the bascule 11 on turning rolls 1 and the pallet 22 is hinged state, therefore, when shelving the turbine rotor of different size, support 1 can rotate around its axle 23, to adapt to the turbine rotor of different-diameter.Used drive can be a duplex chain wheel, and used driving-belt can be the duplex chain bar.
Power transmission shaft 30 is installed at middle part in frame 6, one end of power transmission shaft 30 is installed runner 29, the other end is connected with power transmission shaft 8 by a pair of bevel gear, be connected with screw mandrel 27 by a pair of bevel gear again, screw mandrel 27 is connected with the nut 28 that is installed on the roller support 5, and pallet 22 is installed on the roller support 5.When needs are regulated the horizontal level of pallet 22, can utilize electronic or manual mode rotating wheel 29, driving screw mandrel 27 by power transmission shaft 30,8 and bevel gear thereof rotates, making nut 28 drive roller support 5 slides on rolling element 26, and drive pallet 22, support 1 and roller 2 etc. and move horizontally together, make roller 2 can hold turbine rotor well.
Bascule 11 is installed on pallet 22, is just made support 1 and roller 2 obtain good stable when working with the limit, suspension ring 21 are installed on bascule 11, so that lifting, axle 23 is installed on the bascule 11.Among the figure 3 is bolt, and 4 is packing ring, and 15 is the lifting wheel case, and 16 is the sprocket wheel case, 17 electric control boxes, and 24 is the axle of turbine rotor.
During use: after 1, vehicle frame is placed and to be finished, remove bolt 18 and fixture 19, check the insulation of control cabinet, motor, can debug use after qualified.2, put turbine rotor, utilize free transposition and the lifting handwheel and the runner adjustment turning rolls of turning rolls, make turbine rotor and roller even contact, contact line length reaches more than 90%.When adjusting bracket height, the positive and negative lifting handwheel that shakes makes it be in correct position, shakes then and shores handwheel 31, makes support bar 9 prop up frame 6, and is evenly stressed.3, after control cabinet was connected with the mains, decelerator 13 drove roller 2 and slowly makes forward or reverse, makes turbine rotor be in optimum state, is convenient to service works such as inspection, maintenance, frequency measurement.4, after repairing rotor finishes, must refill bolt 18 and fixture 19, and tight a bolt, in order to transportation and lifting.
