The utility model is made up of two lifting mechanisms, drives two transmission systems in the lifting mechanism simultaneously with a motor.When lower floor's initial point starts elevator and rises to the upper strata terminal point, can close elevator; Equally, when the upper strata initial point starts elevator and drops to lower floor's terminal point, also can close elevator.Two lifting mechanisms all are made up of transmission system, safety system, lubricating system three parts.The principle of work of transmission system is: driven by motor worm screw, worm gear and drive sprocket axle drive drive sprocket, chain and by movable sprocket, drive sprocket is identical with passive teeth number of sprocket by drive sprocket axle.Special chain rivet is installed on a chain link of chain, special chain rivet one end is installed front-slider, the other end is installed rear slider, front-slider and rear slider are placed in respectively in the preceding slide rail and aft ramp on the tressel, when sprocket rotation, chain drives slide block and moves together, thereby drives tressel straight line uniform movement.When moving to arc position, sprocket wheel calibration garden, the motion of special chain rivet, slide block, tressel changes, special chain rivet rotates along sprocket wheel calibration garden track, the relative tressel of slide block is (or upwards) motion downwards in slide rail, tressel is done uniformly retarded motion until stopping half section of garden forearc, does the opposite uniformly accelerated motion of direction in the garden arc second half section then.Upwards move downward in the slide rail discontinuous by slide block, chain-drive is rotatablely moved converts the linear reciprocating motion of tressel to.Owing to had the axle mouth on the aft ramp of tressel, make aft ramp be divided into two parts up and down,

When (D-d)/2＞(L)/2＞H＞d.

In the formula: D---the calibration garden diameter of sprocket wheel

D---sprocket shaft diameter

L---rear slider length

H---tressel aft ramp cross an axle mouthful width, can make the motion of rear slider in aft ramp not mouthful influenced by axle.Guide wheel is installed on the tressel and is carried seat, when bearing weight on carrying seat, guide wheel acts on weight on the guide rail, and weight does reciprocating linear motion along guide rail with tressel, reaches the purpose that object transports up and down.

The principle of work of safety system is: one of steel rope is fixed on tressel top one side, the other end passes two pulleys successively, is installed in the brake shoe of tressel bottom, two pulleys in addition, be fixed on then on the screw of tressel top opposite side, by the elasticity of screw speed governing steel rope.When the tressel crank motion, also be with the steel rope motion.If chain or sprocket shaft split off, the downward slippage of tressel, the brake shoe that braking at this moment the is installed in the tressel bottom tight steel rope of stopping can stop tressel to glide.

The principle of work of lubricating system is: the lower portion in elevator lifting mechanism is installed oil pump, and fuel feeding lubricates transmission system.Lubricating oil returns fuel tank by the back leakage groove that is installed in the transmission system bottom.

The utlity model has simple in structurely, cheap, do not take building area, do not need the special messenger to handle, easy for installation, save energy characteristics.
