The screw mandrel of above-mentioned screw lift is provided with work nut 10 and safety nut 11.
The beneficial effect that the utlity model has:
1, motor train unit bogie truck lifting machine adopts four wheel treads of four lifting column synchronous lifting bogie trucks, does not have track to link to each other between the lifting column, and the space opening between the diaxon is come out, and makes things convenient for the personnel operation maintenance.
2, adjust according to size,, just can satisfy the requirement that operating personal gets into the bogie truck lower space from the side smoothly as long as equipment gives rise to 1.2 meters.Because lift height is low, contour size of the unit(s) reduces, and the basis is also corresponding to be reduced, and has saved the cost of a large amount of equipment costs and basis manufacturing.
3, in order to satisfy two kinds of wheelbases of 2.5 meters of motor train unit bogie trucks and 2.7 meters; Specially designed V-slot can be accurately stable on the lifting head supports wheel tread; And, reach the purpose of the bogie truck of lifting disalignment distance through the location swap of the support roller swash plate on four lifting heads.
4, equipment employing Screw of Worm Gear elevator is a main body, and traditional mechanical synchronization mechanism guarantees the running of equipment efficient synchronization.Lifting device adopts four screw drive forms, and screw thread has auto-lock function, below the work nut of leading screw, safety nut is set so that the work nut when damaging load can all be pressed on the safety nut, guarantee the safety of going up and down.Under the normal working, next plays rotation to safety nut in the drive of work nut, and keep to set spacing between the two, and safety nut does not carry, and after the work nut produced than galling, when setting pitch smaller, control system was reported to the police and auto-stop.
5, equipment adopts online design, has reserved the space of bogie truck stepping delivery system through this equipment, and equipment adopts underground installation form, and during not operation, equipment is fully at below ground, and last plane is concordant with ground.
