Abstract
The utility model discloses a transmission mechanism for an elevator door comprising a drive motor, a left elevator door, a right elevator door, a left hand leading screw, a right hand leading screw, and a ball nut. Wherein the left hand leading screw and the right hand leading screw are arranged symmetrically over a door frame, bearings are arranged on the joint and two ends of the leading screw, the leading screws rotate driven by the motor through a belt, the tops of the left elevator door and the right elevator door are sleeved on the left hand leading screw and the right hand leading screw through the ball nut. The utility model eliminates the phenomena of falling off of the guide pulley lift-type elevator car and saves one third of the transmission elements compared with the general transmission mechanism. The utility model has the advantages of simple structure, complete functions, stable and reliable transmission, rational assembly, convenience for maintenance, beautiful appearance, and lower costing.
Description
Technical field
The utility model relates to a kind of mechanical drive, a kind of more precisely midsplit type elevator door transmission device.
Background technology
At present, the transmission device of various elevators both domestic and external mostly is made up of motor, belt and crank or wire rope pulley assembly, and the motor-driven belt drives door machine link plate by belt by crank or wire rope pulley assembly again, makes elevator door open, close.This elevator door parts are more, complex structure, bulky and manufacturing cost is high, owing to adopted guide wheel suspension type gate structure, therefore occur Room door obscission easily.To this, many patented products were all done improvement to the elevator door transmission device, as Chinese patent CN02216640.8 disclosed " elevator door-motor gear, rack gear " and Chinese patent CN200420114082.4 disclosed " elevator center opening door machine transmission device ", though these products have certain progress, but still can not overcome the problems referred to above fully, result of use is not satisfactory.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model be to provide a kind of simple in structure, multiple functional, stable drive reliable, elevator door transmission device reasonable, easy to maintenance is installed.This elevator door transmission device adopts multi-thread big helical pitch rolling screw drive mechanism, can save driving parts 1/3rd.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of elevator door transmission device, comprise drive motor, left elevator door, right elevator door, left-handed leading screw, dextrorotation leading screw and ball nut, left-handed leading screw and dextrorotation leading screw are erected at the doorframe top symmetrically, its joint and two ends are equipped with bearing, motor drives leading screw by belt and rotates, and the top of left elevator door, right elevator door is set on left-handed leading screw and the dextrorotation leading screw by ball nut.
Fast left-handed leading screw of institute and dextrorotation leading screw connect by axle sleeve, and axle sleeve is fixed in the bearing hole at doorframe middle part.
The side of being fixed with, the top cover of described left elevator door, right elevator door is in the ball nut side of the being installed in cover.
The top of described left elevator door, right elevator door is respectively equipped with two prescriptions cover and ball nut.
Described belt is trapezoidal synchronous cog belt or polywedge bet, and the outwardly directed end of motor output shaft and leading screw is equipped with the belt pulley suitable with it.
Described motor is a buncher.
Principle of work of the present utility model is: frequency control motor drives to ball-screw by trapezoidal timing belt, drive the ball nut displacement, when ball-screw under frequency control motor drives during forward and reverse revolution, ball nut is forward and reverse thereupon to be moved, captive joint with side's cover because of ball nut, side's cover is captiveed joint with elevator door again, so door also moves thereupon, because of ball-screw center line two ends are respectively left and right sides helix line, therefore two fan goalkeeper's foldings simultaneously again.
The utility model has been eliminated the shortcoming that there is obscission in guide wheel suspension type gate, compare with the general-duty transmission device and can save driving parts 1/3rd, have simple in structure, multiple functional, stable drive reliable, beneficial effects such as reasonable, easy to maintenance, handsome in appearance, cheap are installed.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of reference numerals is as follows:
The left elevator door of 1---buncher 2---
The left-handed leading screw of 3---right elevator doors 4---
5---dextrorotation leading screw 6---ball nut
7---axle sleeve 8---middle part bearing
9---bearings at both ends 10---belt pulley
11---trapezoidal synchronous cog belts 12---side cover
Elevator door transmission device embodiment as shown in Figure 1, its main parts size has buncher 1, left side elevator door 2, right elevator door 3, left-handed leading screw 4, dextrorotation leading screw 5 and ball nut 6, left-handed leading screw 4 is erected at the doorframe top symmetrically with dextrorotation leading screw 5, both connect by axle sleeve 7 at the doorframe middle part, axle sleeve 7 is fixed in the endoporus of bearing 8, realize interlock with this, the end that two leading screws stretch out doorframe is respectively installed with bearing 9, be equipped with belt pulley 10 on the outer end of the output shaft of frequency control motor 1 and left-handed leading screw 4, buncher 1 drives leading screw by trapezoidal synchronous cog belt 11 and rotates, the top of left side elevator door 2 is fixed with two side's covers 12 abreast, in side's cover ball nut 6 is installed, left side elevator door 2 is sleeved on the left-handed leading screw 4 by ball nut 6, and right elevator door is sleeved on the dextrorotation leading screw 5 in the same way symmetrically.The shift position of elevator door is by the control of contact pointless permanent-magnetic switching, and the encoded device of the variation of moving velocity makes frequency control motor change voltage and realizes, adopts current techique both can realize, just repeats no more here.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; though but on its shape or structure, do any variation, the door machine of the multi-thread big helical pitch rolling screw transmission device of every employing is all within its protection domain.
