Abstract
The invention discloses a screw-type door plate opening and closing mechanism of an elevator cage, comprising a main body which is arranged in the elevator cage and is provided with a screw set, a driven set and two tracks; the outer edge of the long axis of the screw set is provided with a first helical rolling ditch and a second helical rolling ditch, the length of the first rolling ditch is less than that of the second rolling ditch, the lead of the first rolling ditch is less than that of the second rolling ditch, a first moving block is provided with a first rolling groove rolling corresponding to the first rolling ditch, and a second moving block is provided with a second rolling groove rolling corresponding to the second rolling ditch. As the first helical rolling ditch and the second helical rolling ditch of different leads are arranged on the long axis, a first door plate and a second door plate of the cage have different running speeds to achieve the functions of opening and closing, thus greatly simplifying the existing door plate opening and closing mechanism of the elevator cage and greatly reducing the production cost of the door plate opening and closing mechanism of the elevator cage, and moreover, the door plate opening and closing mechanism of the elevator cage is applicable to small-sized elevator cages.
Description
Technical field
The present invention relates to a kind of part of conveying arrangement, be specifically related to a kind of screw type elevator compartment door-plate mechanism for opening/closing.
Background technology
Transport personnel with elevator at present or goods is very general, recent many construction companies with elevator installation in the villa of low floor, use with convenient old or handicapped people, but it is limited and should reflect and take advantage of manned number few because of the space of villa, so it is comparatively universal with the compartment of miniaturization, and the design of other relative mechanisms is also dwindled relatively, and wherein the mechanism for opening/closing of elevator door is the problem that the present invention will improve.
For example, TaiWan, China is announced the disclosed elevator door mechanism for opening/closing of patent case No. 382372, see also this case Figure of description, be provided with an angle bar 32 by boatswain chair 31 a tops lock knot, horizontal direction each knot in front and back end, angle bar 32 top is established a pulley 33,34, and No. two boatswain chair 41 tops lock knots are provided with No. two U-shaped plates 45 and an angle bar 42, and establish a pulley 43,44 in each knot of front and back end, angle bar 42 top vertical direction, and No. three boatswain chair 51 tops locks have No. three U-shaped plates 52; Again, have a rope walk around respectively before and after two horizontal trolleys 33,34 and rope ends lock tie on No. two U-shaped plates 45 of two bugle iron, 42 tops, and rope one place system is locked on the rope consolidation board 27 of box body wallboard 28, its state such as this case Figure of description shown in Figure 7; Other has a rope to walk around front and back two vertical sliding wheels 43,44 respectively, and the rope ends lock is tied on No. three U-shaped plates 52 of No. three boatswain chair 51 tops, and rope one place system is locked in and fixedly prolongs on the plate 35 1 end ends, and this fixedly to prolong plate 35 other ends be to stride across No. two boatswain chair 41 top angle bar 42 and be locked on the angle bar 32 of boatswain chair 31 tops.
This kind pulley combination mode, when elevator door starts, gangbar 23 can promote door-plate 25 motions that connecting rod 24 drives No. three outstanding knots in boatswain chair 51 belows again, and No. three boatswain chairs 51 are again by No. two boatswain chairs of two groups of assembly pulley interlocks 41, a boatswain chair 31, make three door-plates 25 produces soon respectively in slow a certain proportion of kinematic velocity.
In addition, announce the patent case No. 540569 as TaiWan, China, see also this case Figure of description, it is 1: 2: 3 forming with shaft pulley 36,37,38 by a drive wheel by three impeller diameter ratios mainly, and rule belt 30 when respectively sheathed, below belt 30 respectively with connecting element 31, fixedly fixed plate 32, gantry crane plate 40,41,42 and elevator door; Driving the belt pulley 36,37,38 that drives wheels by power wheel 39 when motor running rotates, thereby drive gantry crane plate 40,41,42 and elevator door and make switching motion, utilize the proportionate relationship of belt pulley 36,37,38, make each elevator door have the different speed that open and close, when opening and closing, also can make the kinematic velocity of each door-plate keep the same ratio relation.
So, the employed mechanism of above-mentioned two prior aries is that pulley and cable wire or belt pulley and belt make the elevator door action, and this mechanism's complexity, installs or maintenance all is difficult for.Emphasis is can't miniaturization, and increases the door opener additional space requirement.
