Preferably, a limiting groove is provided on the outer side of the rotating cylinder, and two limiting half-rings are arranged on the upper end of the limiting cylinder, and the two limiting half-rings are inserted into the limiting grooves.

Preferably, a fixing ring is arranged on the upper end of the rotating drum, and a short rod is arranged on the fixing ring.

Preferably, the upper end of the limiting cylinder is provided with a fixing block, the upper end of the fixing block is provided with a mounting plate, a motor is mounted in the middle of the mounting plate, a driving pulley is mounted on the rotor shaft of the motor, and the rotating cylinder is A driven pulley is arranged on the top, and the driving pulley and the driven pulley are connected by a belt drive.

Compared with the prior art, the beneficial effect of the present utility model is: by setting the support mechanism that can adjust the support height by electric or manual mode, it can be flexibly used in the support work of elevator foundations of different heights, and it is very easy to use. convenient.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Please refer to FIG. 1 and FIG. 2 , the embodiment of the present invention provides an adjustable support for the construction of the elevator foundation on the basement roof 8, including a bottom plate 1, a center column 101 is welded on the upper end of the bottom plate 1, and a bearing 2 is sleeved on the lower end of the center column 101, The upper end of the central column 101 is welded with a threaded column 102, and a blocking cap 3 is threadedly installed on the threaded column 102 to limit the bearing 2. The outer side of the bearing 2 is sleeved with a rotary cylinder 4, and the upper end of the bottom plate 1 is installed with a limit cylinder 5 through bolts , the limiting cylinder 5 is sleeved on the outside of the rotating cylinder 4, and is used for limiting support to the rotating cylinder 4. The inner thread of the rotating cylinder 4 is installed with a lifting pipe 6, the upper end of the lifting pipe 6 is welded with a supporting plate 7, and the upper end of the supporting plate 7 is A top plate 8 is mounted by bolts for supporting the elevator foundation.

Please refer to FIG. 1 , a limit groove 401 is defined on the outer side of the rotating cylinder 4 , and two limit half rings 9 are installed on the upper end of the limit cylinder 5 by screws. The two limit half rings 9 are inserted into the limit groove 401 for The rotary drum 4 is limited in the vertical direction. A fixing ring 10 is installed on the upper end of the rotating drum 4 through screws, and a short rod 11 is welded on the fixing ring 10 for manually pushing the rotating drum 4 to rotate. A fixing block 12 is welded on the upper end of the limiting cylinder 5, a mounting plate 13 is installed on the upper end of the fixing block 12 through bolts, and a motor 14 is installed in the middle of the installation plate 13 through bolts. The model of the motor 14 used is 5IK60RGU-CF. A driving pulley 15 is installed through a key connection, and a driven pulley 16 is welded on the rotary drum 4 .

The working principle of this embodiment is as follows: when in use, first connect the motor 14 to an external power supply cable, then start the motor 14, the rotor shaft of the motor 14 drives the driving pulley 15 to rotate, and the driving pulley 15 drives the driven pulley through the belt. 16 rotates, and the driven pulley 16 drives the rotary drum 4 to rotate. When the rotary drum 4 rotates, the limiting half ring 9 limits the rotary drum 4 in the vertical direction, and the rotary drum 4 drives the lifting pipe 6 to move in the vertical direction through the screw connection. In this way, the lifting tube 6 drives the top plate 8 to move up and down, so as to realize the adjustment of the support height. When the top plate 8 stands against the elevator foundation, stop the motor 14. When the power supply is lacking, it can be pushed by manually holding the short rod 11. The rotary drum 4 is rotated to adjust the height of the lift pipe 6 .

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
