Problems solved by technology

[0002] For example, the public number CN201030241Y is a loose and broken rope protector for a stage hoist, comprising a guide rod, on which a first and a second trigger mechanism are housed, and the two trigger mechanisms are composed of a support, a guide shaft, a pulley, a micro switch, Connecting plate, torsion spring and limit screw. The bracket is composed of back plate, left wing plate and right wing plate. The left wing plate and right wing plate are respectively fixed at the two ends of the back plate. Between them, the bottom ends of the left and right wing plates are pivotally connected to the guide rod, the connecting plate is welded on the back plate, the micro switch is fixed on the connecting plate through fasteners, and the limit screw is fixed on the guide rod. The position of the screw corresponds to the position of the trigger plate on the micro switch, the torsion spring is sleeved on the guide rod, and the two ends of the torsion spring are fixedly connected with the limit screw and the connecting plate respectively; the disadvantage of this invention is that it cannot automatically Adjust lifting torque

Abstract

The invention relates to an elevator, in particular to a stage elevator which comprises an elevating chassis, a winding mechanism, a mounting support, a pulling mechanism, a lifting mechanism, a powermechanism and a transmission mechanism. The winding mechanism is rotatably connected to the elevating chassis, the mounting support is slidably connected to the elevating chassis, and the mounting support and the winding mechanism are in meshing transmission. The pulling mechanism is connected to the mounting support in a sliding mode, the pulling mechanism is connected to the power mechanism ina rotating mode, the power mechanism is fixedly connected to the mounting support, an object needing to be hoisted can be mounted on the lifting mechanism, the lifting mechanism is fixedly connected to the winding mechanism, and the power mechanism drives the transmission mechanism to rotate. The transmission mechanism drives the winding mechanism to rotate, the winding mechanism drives the lifting mechanism to ascend and descend, the lifting mechanism feeds back the weight of the object to the pulling mechanism, the pulling mechanism changes the transmission ratio between the transmission mechanism and the power mechanism, and then the torque output by the transmission mechanism is changed.
