Described screw mandrel drives the lift work platform, it is characterized in that described fixedly lower mast is fixed on the base, and this base is provided with by motor-driven reductor, and described screw mandrel links to each other with the output shaft of reductor.
Described screw mandrel drives the lift work platform, it is characterized in that the input end of described reductor is furnished with motor and manual power input media.
Described screw mandrel drives the lift work platform, it is characterized in that the height of the length of described screw mandrel and the first movable lower mast is suitable.So that screw mandrel has maximum stroke as much as possible.
Compared with prior art, technical scheme provided by the utility model has following technique effect:
1,,, makes the self-locking safely of lift work platform so screw mandrel transmission replacement hydraulic ram drives thus because the screw mandrel transmission has good self-locking property;
2, this mode that drives by the screw mandrel transmission, the synchronism in the time of can utilizing consistent screw mandrel pitch to guarantee the common operation of many lift work platforms;
3, can manual working, when propulsion source (as motor) can not be worked, can drive screw mandrel by reductor by the manual power input media, make the complete machine normal operation;
4, adjustable height ratio enlarger links to each other by screw thread pair with screw mandrel, belongs to pure mechanical drive, does not have oil leakage phenomenon, uses in the demanding place of cleaning to have no adverse effects; And be convenient to safeguard.

[specific embodiment]
As shown in Figure 1, this screw mandrel drives lift work flat-bed principle of work and is: fixedly lower mast 3 is fixed on the underframe 1, and first movable lower mast 6 bearing fits are fastened in fixedly in the lower mast 3, by screw mandrel 4 direct jackings; Second movable lower mast 7 bearing fits are fastened in the first movable lower mast 6, and the 3rd movable lower mast 8 bearing fits are fastened in the second movable lower mast 7; Between fixing lower mast 3 upper ends and the second movable lower mast, 7 lower ends, between the first movable lower mast, 6 upper ends and the 3rd movable lower mast 8 lower ends, be connected one section conduction chain 9 respectively, and two sections conduction chains are engaged on respectively on the rolling chain wheel on the first movable lower mast upper end and the second movable lower mast; When the first movable lower mast 6 during by the screw mandrel lifting, the transmission by chain 9 is risen the second movable lower mast 7 synchronously, in like manner, promotes the 3rd movable lower mast 8, and then will be lifted to the workplatform that the 3rd movable lower mast is captiveed joint and require height; After this mechanism's amplification, stroke amplifies three times.Otherwise it is as the same to descend.
Shown in Fig. 2～4, be single lower mast version of the present utility model: its adjustable height ratio enlarger comprises fixedly lower mast 3, first movable lower mast 6, second movable lower mast 7 and the 3rd movable lower mast 8 that is served as by the high strength aluminum alloy section bar: fixedly lower mast 3 is fixed on the base 1, the first movable lower mast 6 is fastened in fixedly in the lower mast 3, the second movable lower mast 7 is fastened in the first movable lower mast 6, and the 3rd movable lower mast 8 is fastened in the second movable lower mast 7; Between fixing lower mast 3 upper ends and the second movable lower mast, 7 lower ends, between the first movable lower mast, 6 upper ends and the 3rd movable lower mast 8 lower ends, be connected one section board-like hoisting chain respectively, and two sections board-like hoisting chains are engaged on respectively on the sprocket wheel on the first movable lower mast upper end and the second movable lower mast as traction piece; In addition, fix a nut 5 in the first movable lower mast, 6 lower ends.Its actuating unit comprises reductor 2 that is fixed on the base and the motor 10 that links to each other with reductor, and this motor 10 is connected with reductor.The lower end of Acme thread screw mandrel 4 links to each other with the output shaft of reductor 2, and its upper end is screwed onto with the nut 5 that is fixed on the first movable lower mast lower end, thereby forms the screw mandrel transmission.The screw mandrel that is formed by these concrete technical measures drives the lift work platform, ability with three times of amplifications: if the lifting travel of screw mandrel is 1600mm, then three sections lower masts can reach the adjustable height of 4800mm, adjust the rotating speed of screw mandrel, can control operation flat-bed rising or falling speed.On the basis of this specific embodiment, setting up handwheel between motor and the reductor as the manual power input media: when motor can not be worked, manually shake handwheel, make the complete machine normal operation.
As another kind of embodiment, be that fourth mast rod structure in " the fourth mast post high-altitude operation platform " of CN2304648Y replaces the single lower mast structure in the above-mentioned specific embodiment with notification number, can strengthen the rigidity of adjustable height ratio enlarger.
Shown in Fig. 5,6, it is the performance that drives a large-scale job platform 17 of the common lifting of lift work platform with eight screw mandrels, it drives lift work platform 13 by an electrical motor 11 by a reductor 12 and some T fonts deflector 14 with by the screw mandrel that coupler 16 bonded assembly transmission shafts 15 drive eight single lower mast structures, realizes the synchronization lifting of large-scale job platform.Motor is by different two kinds of explosion proof type and the coventional types of dividing of use occasion.In order to protect transmission shaft, it is dull and stereotyped that the zone that whole transmission shaft passes is provided with ground; For the convenience of workpiece turnover, the sloping is done at the two ends of ground flat board.This installs main application example: elevator stage, passenger vehicle are repaired originating firm, aerospace industry etc.
