The device of above-mentioned vertical-lift axle or stock parts, the sidewall of described lifting screw-casing has screw, is rotary with jackscrew in screw, the periphery close contact of the front end of jackscrew and axle or stock, and the rear end face of jackscrew is lower than bottom the external screw thread promoting screw-casing.
The device of above-mentioned vertical-lift axle or stock parts, the bottom surface of described rotating nut there is the annular groove around rotating nut circumference, in support platform, plane has the annular groove around through hole circumference, the annular groove of rotating nut bottom surface is corresponding with the annular groove of plane in support platform, multiple support ball is embedded between two relative annular grooves, and multiple support ball is along annular groove circumference uniform distribution.
The device of above-mentioned vertical-lift axle or stock parts, the sidewall of described rotating nut has 2-4 jack, and jack is along the circumference uniform distribution of rotating nut, and the end of rotating handles is inserted in jack.
The beneficial effects of the utility model are:
Lifting screw-casing of the present utility model is fixedly connected with axle or stock, and lifting screw-casing and axle or stock can not be rotated, rotating nut is sleeved on and promotes on screw-casing, rotate rotating nut, drive and promote screw-casing axially spiral, band moving axis or stock jointly upwards, reach the object of vertical-lift axle or stock.The utility model structure is simple, easy to use, the narrow space vertical-lift axle or the stock parts that use hanging device can be not suitable for, promote after putting in place and can also rotate in the screw of insertion, very convenient, not only decrease construction and maintenance time, substantially increase operating efficiency, also reduce the labour intensity of workman, ensure that the safety of produced on-site.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: promote screw-casing 1, rotating nut 2, support platform 3, support ball 4, jack 5, axle or stock 6.
Detailed description of the invention
The utility model comprises lifting screw-casing 1, rotating nut 2, support platform 3, supports ball 4.
Show in figure, promote the periphery that screw-casing 1 is sleeved on axle or stock 6, promote screw-casing 1 inwall and axle or stock 6 periphery and be fastenedly connected.The sidewall promoting screw-casing 1 there is screw, is rotary with jackscrew in screw, the periphery close contact of the front end of jackscrew and axle or stock 6, bottom the rear end face of the jackscrew external screw thread lower than lifting screw-casing 1.The outer wall of jackscrew lifting axe or stock 6, makes axle or stock 6 can move upward with lifting screw-casing 1, and the rear end face of the jackscrew of jackscrew, lower than bottom the external screw thread promoting screw-casing 1, can not affect rotating nut 2 along the rotation promoting screw-casing 1 screw thread.
Show in figure, the outer wall of lifting screw-casing 1 has rotation screw thread, the endoporus of rotating nut 2 has screw thread to match with the external screw thread promoting screw-casing 1, and rotating nut 2 is sleeved on the periphery of lifting screw-casing 1, and the outer wall of rotating nut 2 has rotating handles.Rotate rotating nut 2, promoting thread bush 1 can axially move up and down.
Show in figure, support platform 3 is in the below of rotating nut 2, and the bottom surface of rotating nut 2 is relative with the upper plane of support platform 3, and there is through hole at the center of support platform 3, promotes screw-casing 1 and axle or stock 6 and wears in through-holes, can move up and down.
