Summary of the invention

The objective of the invention is to provide a kind of jacking elevator that drives by the tractive driven shearing fork telescopic lifting mechanism work, make strength transmission, drive the lifting of variation scissors rod angle jacking lift car with the drag-line tractive with drag-line and pulley.

The object of the present invention is achieved like this: drawing-off driving shearing top lifting elevator is made up of hoistway, guide rail, car, control panel and neoteric tractive driven shearing fork telescopic lifting mechanism etc.Car places between the guide rail of hoistway, the tractive driven shearing fork telescopic lifting mechanism of car bottom is formed by cutting fork row, drag-line, pulley unitor, tractive actuating unit and base, control panel is handled control tractive actuating unit and is tightened up release or static drag-line tractive, change or limit scissors rod variable angle state through pulley unitor transfer function strength, realize lift car lifting, stop layer and keying etc.The application tractive driven shearing fork telescopic lifting mechanism is done the jacking driving can be according to different demands and load, forms and variously cut the combined scissors fork mechanism that the fork row are mutually the angle combination form and bear telescopic lifting, drive telescopic lifting to all cutting fork row application drag-line through the pulley unitor by two, to a plurality of fork row cut by two applicable to various types of elevators or lifting table.

The up-to-date technology of drawing-off driving shearing top lifting elevator application tractive driven shearing fork telescopic lifting mechanism is done the elevator jacking and is driven, and structural shape is rationally various, telescopic lifting is steadily reliable, support firm strong, powerful complete, the control economical operation low consumption of safety control of jacking.Compare with the hydraulic elevator of accurate complex and expensive, its structure letter makes that easy cost is low, fault is safeguarded just effect height less, can replace the main force that hydraulic elevator etc. becomes the jacking elevator fully.
