It is dynamic, being accurately positioned for radial loaded mechanism is completed, and load at this time is defined as zero.
The advantages of radial loaded mechanism of the present invention, is the crossbeam that two screw thread elevators 6 are installed on to babinet girder construction
On 7, the upper and lower ends of screw 8 are fixed in rack with flange, and the rotating nuts in such screw thread elevator 6 are in motor reducer
When being rotated under 2 drive, screw 8 does not turn, and crossbeam 7 is used as hoistable platform, moves up and down.Whole equipment is compact-sized, volume
It is small, light-weight, two screw thread elevators 6 are applied in combination, adjustment hoisting depth can be controlled exactly, driven with motor reducer 2
Dynamic, motor reducer 2 is connected with the screw thread elevator 6 of left and right two respectively by two universal shafts 4, there is provided the synchronization of same rotational speed
Power, ensure that the lift in height at crossbeam both ends is synchronous, completes the coarse positioning of radial loaded.
The above is only the better embodiment to the present invention, not makees limit in any form to the present invention
System, any simple modification that every technical spirit according to the present invention makes embodiment of above, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
