Useful technique effect of the present utility model is: apparatus structure of the present utility model is simple, easy to use, can realize measurement and adjustment that large-size horizontal centrifugal pump is lifted axle dismounting and bottom bearing shell and the rotor part amount of lifting are installed, and work efficiency is high.Can avoid the damage to equipment such as pump shafts.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of centrifugal pump of horizontal axis provided by the utility model is lifted shaft device;
Fig. 2 is the use schematic diagram that a kind of centrifugal pump of horizontal axis provided by the utility model is lifted shaft device.
In figure: 1. supporting leg, 2. bottom jackscrew beam, 3. top lifting beam, 4.U type enhancing ring, 5. jackscrew handle, 6. jackscrew, 7. nut, 8. pad, 9. pump shaft, 10. bearing chamber platform.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of large-size horizontal centrifugal pump provided by the utility model is lifted shaft device and is comprised supporting leg 1, bottom jackscrew beam 2, top lifting beam 3, U-shaped enhancing ring 4, jackscrew handle 5, jackscrew 6, nut 7, pad 8.Bottom jackscrew beam 2 two bottom sides are respectively arranged with a supporting leg 1, and supporting leg 1 top is plugged in bottom jackscrew beam 2, and all by screw thread, are fixed and connected between bottom jackscrew beam 2 and two supporting legs 1.Bottom jackscrew beam 2 middle top surface are provided with top lifting beam 3, bottom jackscrew beam 2 and top lifting beam 3 are all run through in the both ends of U-shaped enhancing ring 4, and between U-shaped enhancing ring 4 and top lifting beam 3, by nut 7, pad 8, be fixedly connected with, the line of centers of U-shaped enhancing ring 4 overlaps with the line of centers of bottom jackscrew beam 2, top lifting beam 3.Top lifting beam 3 is run through in jackscrew 6 bottoms, and jackscrew 6 bottoms are embedded in the Baltimore groove of bottom jackscrew beam 2 top center, between jackscrew 6 and top lifting beam 3, by screw thread, is fixed and is connected.Jackscrew is plugged with jackscrew handle 5 in 6 tops, and the axis of jackscrew 6 is mutually vertical with the axis of jackscrew handle 5, and by screw thread, is fixed and connected between the two.
U-shaped enhancing ring 4 adopts brass to make, and avoids pump shaft 9 to cause damage, and other parts are carbon steel and make.The bottom surface of supporting leg 1 has roughness, avoids lower bearing chamber platform 10 to cause damage.The Baltimore groove of bottom jackscrew beam 2 is for the location of jackscrew 6.Nut 7 is spacing for U-shaped enhancing ring 4.
When using this centrifugal pump of horizontal axis to lift shaft device, this supporting leg 1 of lifting shaft device is vertically positioned on pump lower bearing chamber platform 10, pump shaft 9 is inserted in U-shaped enhancing ring 4, then adjust the nut 7 on top, to U-shaped enhancing ring 4 lower inside walls and pump shaft 9 bottoms, be close to, afterwards clickwise jackscrew handle 5 again, jackscrew 6 will rotate to jackscrew beam 2 concave grooves of bottom, along with jackscrew handle 5 and the continuous clickwise of jackscrew 6, will drive the lifting of pump shaft 9, thereby realize lifting of pump shaft 9.
In conjunction with the accompanying drawings and embodiments the utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make various variations.The content not being described in detail in the utility model all can adopt prior art.
