Description
Technical field
The present invention relates to three upward swing door link gears of a kind of elevator, belong to the electric door driving device of elevator, utilize equilibrium principle, driven the mechanism of a kind of three upward swing doors interlock mode of steel rope and power wheel running by gear drive.
Background technology
Most door-opened elevator mode all adopt common side open or in point, grading mode in two-fold, the size that this mode is opened the door has limitation to elevator hoistways width, thereby causes under special circumstances door opening width and highly all can not meet customer need.
Elevator is as a kind of special special equipment, reaching under safe prerequisite, also should meet some specific (special) requirements of client, and institute thinks and meets client and the market demand, addresses the above problem and is necessary to develop the special electric door driving device of a kind of application.
Most two fans that adopt of link gear elevator door of door, also have three fans or four fans.In the open and close process of door, in the time adopting simple gate cutter, gate can only be associated device by door and directly drive a fan layer door, and the motor coordination between layer every fan realizes by link gear.
(1) its general steel wire rope type link gear that adopts of midsplit type layer door linking mechanism.Door guide rail bracket two ends installing wire rope pulley, two fan doors respectively with the top of steel rope be connected below, when door cutter drive Yishanmen moves, the motion of steel rope is moved another Yishanmen round about.
While adopting this structure, two rope sheaves on guide rail bracket should have spacing to adjust position, or should be adjustable in one end of shackle line, so that the adjustment to steel wire tensioning power.
(2) other open type layer door linking mechanism
1), steel wire rope type: steel rope is walked around two pulleys on slow door, and two ends are fixed on upper door frame, shutter is fixed on the steel rope in the middle of two pulleys, and slow door guide roller is movable pulley, is 2:1 thereby make speed ratio fast, slow door.The door lock of general layer door is contained on shutter, and door cutter, by door lock pulley, first drives shutter motion.
This door leaf by indirect mechanical connection except fast door lock electric, also must have electric safety device to confirm the off position of slow every fan on slow door (driven door), guarantees that arbitrary door leaf do not cut out and put in place, the equal fail to start of elevator.
2), single folding-jib: adopt three folding arms, the point of connection between folding arm and attachment point and the folding arm of door is hinged.Folding arm stock between each hinge-point is equal in length, and has three to be fixedly hinged a little in the same horizontal line.In the time that folding arm mechanism is made folding movement, can realize fast, slow door velocity ratio is 2:1.
3), two-fold is arm-type: the principle of work of layer door linking mechanism is identical with single folding-jib, owing to being two-fold arm, becomes X-shape, so action is more steady.4), oscillating rod type: fork lower end is hinged fixing, and upper end is connected with shutter by connecting rod, centre is connected with slow door by connecting rod, and fork swings under the drive of shutter, thereby makes slow door linkage.Layer door self-closing device assurance elevator, in the time of normal operation, can not be opened layer door. in the 7.7.3.2 bar of standard GB/T 7588, stipulate:
The in the situation that of gate driving layer door, in the time that car is beyond onlocking zone, if no matter layer door be because which kind of former thereby unlatching should have a kind of device (pouring weight or spring) can guarantee automatically closing of this layer of door.At present, a layer door self-closing device has two kinds of weight hammer type and spring loadeds.
Summary of the invention
The object of the invention is: provide a kind of elevator three upward swing door link gears.The maximization of opening the door for meeting under specific circumstances lift car.
The object of the invention is achieved through the following technical solutions: three upward swing door link gears of a kind of elevator, drive rapid door, middling speed door and at a slow speed door, open along the guide rail being supported by pillar stiffener, closed, there is sufficient intensity sill one of pillar stiffener bottom installing, to bear the load that enters car by it, crossbeam is established on two pillar stiffener tops, door leaf is divided into rapid door from the bottom to top, middling speed door and at a slow speed door, on a left side, both sides for door leaf, on right support post, be respectively equipped with a left side, right guide rail, the top of door leaf arranges power axle, steel rope left and right fixed port, drive steel rope to draw respectively rapid door by CD-ROM drive motor through driving gear set, middling speed door and at a slow speed door, adopt same steel rope to be fixed on same door-plate, wherein,
Two ends of described middling speed door are fixed two independently left and right sprung partses, it is the first transmission door leaf that one end utilizes steel cable to get back to the middling speed door other end through driving gear set again after top power axle, CD-ROM drive motor and driving gear set are around to counterbalanced weight, that is: the first described transmission door leaf is to utilize two middling speed door leafs that independently sprung parts is connected through devices such as top power axle, CD-ROM drive motor and driving gear set steel cable with counterbalanced weight;
