Existing SC series building hoist two transmission device is normal correspondingly uses two clutches, the axis being parallel of general Gear axis and clutch and same plane, and this driving device is not when a clutch rotates, and another clutch will bear larger power; In transmission, engagement force pass order is from gear-tooth bar-clutch, the centre distance of two clutches is short, and as shown in Figure 1, existing clutch axis is parallel with Gear axis and in same level, this arrangement form makes tooth bar stressed comparatively large, easily causes rack and pinion wear phenomenon.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, simply compact, Assembly &Disassembly is convenient, reliable, can operational shock be reduced, improve the two-stage drive of the lifting mechanism of output gear and tooth bar wearing and tearing.
The technical scheme in the invention for solving the above technical problem is: the two-stage drive of this lifting mechanism, comprise driver plate and driving frame, described driver plate is arranged on driving frame, it is characterized in that: also comprise tooth bar, gear and at least three clutch bodies, described gear contacts with tooth bar, and described gear and at least three clutch bodies are installed on driver plate; Increase a clutch, output gear and tooth bar wear phenomenon can be improved by actv., improve elevator operation stability, extend complete machine service life.
As preferably, the quantity of clutch body described in the utility model is three, and the quantity of described gear is two, and described tooth bar is between three clutch bodies and two gears; Make clutch stressed more reasonable.
As preferably, clutch body described in the utility model comprises axle, and one end overcoat of described axle has bearing, and this bearing outside has roller, and the other end overcoat of described axle has eccentric shaft.
As preferably, clutch body described in the utility model is fixed with driver plate through after axle by bolt.
As preferably, in three clutch bodies described in the utility model, have two clutch bodies and described tooth bar rear-face contact at least; Two clutches, along tooth bar rear-face contact, can reduce operational shock, effectively improve gear and tooth bar wearing and tearing.
As preferably, the roller periphery of clutch body described in the utility model and the back gap adjustable of described tooth bar; Prevent cage from occurring chatter phenomena.
The utility model compared with prior art, has the following advantages and effect: 1, reasonable in design, by increasing a clutch, can improve output gear and tooth bar wear phenomenon by actv., improves elevator operation stability, extends complete machine service life; 2, compared with existing elevator two transmission device two clutches, three clutch opposed vertical direction tooth bars arrange that distance is longer, in operational process middle rack not only uniform force, and its distortion can be prevented and swing by actv., when transmission device is moved along tooth bar up and down by pinion rotation on guide rail bracket, have at least two backrest wheel and rack rear-face contact to roll, operational shock chance can be reduced, improve output gear and tooth bar wear phenomenon simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
Embodiment.
See Fig. 2 to Fig. 6, the two-stage drive of the present embodiment lifting mechanism mainly comprises driving frame 1, driver plate 2, tooth bar 3, gear 4 and clutch body 5.
Driver plate 2 in the present embodiment is arranged on driving frame 1, and gear 4 contacts with tooth bar 3, and gear 4 and clutch body 5 are installed on driver plate 2.
The quantity of the clutch body 5 in the present embodiment is three, i.e. the first clutch body 6, second clutch body 7,3rd clutch body 8, the quantity of gear 4 is two, tooth bar 3, between three clutch bodies 5 and two gears 4, has two clutch bodies 5 and tooth bar 3 rear-face contact at least in three clutch bodies 5.
Clutch body 5 in the present embodiment comprises axle, and one end overcoat of axle has bearing, and bearing outside has roller, and the other end overcoat of axle has eccentric shaft, and clutch body 5 is fixed with driver plate 2 through after axle by bolt.
The roller periphery of the clutch body 5 in the present embodiment and the back gap adjustable of tooth bar 3, can prevent cage from occurring chatter phenomena.
The present embodiment is in motion process, and have at least two clutch bodies 5 to roll with the rear-face contact of tooth bar 3, situation has following four kinds.
See Fig. 3, for clutch body 5 and tooth bar 3 touch scrolling situation schematic diagram one, first clutch body 6, second clutch body 7 and the 3rd clutch body 8 all with tooth bar 3 rear-face contact, gear 4 is about arranged on the horizontal center line between two clutch bodies 5, the distance of three relative tooth bars 3 of clutch body 5, it is more reasonable to arrange, the first clutch body 6, second clutch body 7 is equal with the distance of tooth bar 3 in the vertical direction with the 3rd clutch body 8.
