Description
Technical field
The utility model is related to a kind of door mechanism of the car of elevator, more particularly to a kind of belted car
Door mechanism.
Background technology
Car door mechanism is generally divided into center opening door type and side opening door type.The car door mechanism of side opening door type includes
Shutter and slow door.At present, side opening door type is usually to drive chain drum using motor, and chain drum drives rocker arm body, on rocker arm body
Set up some connecting rods and realize the movement velocity and move distance control of shutter and slow door.Such as：Applicant was at 06 month 2014
The Chinese patent application of 16 entitled " the integrated side opening door devices of elevator door " for proposing, notification number is the U of CN 204022227.
But there is connecting rod is more, weight is weighed, big, the installation difficulty that takes up space is big etc. in the car door mechanism of this spline structure
Problem.
For this reason, it may be necessary to be improved to existing car door mechanism.
The content of the invention
The utility model provides a kind of simple structure, lightweight, the simple car door machine of the small, installation that takes up space
Structure.
Using following technical scheme：
Car door mechanism, including fast door track and slow door track；Shutter sliding block is configured with fast door track；In slow door track
Slow door sliding block is configured with road；Also include motor；Especially, also filled including the reciprocating action driven by the motor
Put；The shutter sliding block is driven by the reciprocating action unit and makees straight reciprocating motion；It is additionally provided with first pulley, the second cunning
Wheel, the first steel wire rope and the second steel wire rope；The first pulley and second pulley are arranged at slow door sliding block；The shutter sliding block is made
When enabling direction is moved, shutter sliding block drives slow door sliding block to make enabling direction by the cooperation of the first steel wire rope and first pulley
Motion；The shutter sliding block closes the door direction when moving, and shutter sliding block is driven by the cooperation of the second steel wire rope and second pulley
Slow door sliding block is closed the door the motion in direction.
Operation principle of the present utility model is as follows：
The utility model constitutes the mechanism that a set of " reciprocating action unit-shutter sliding block-slow door sliding block " is so driven successively,
It is different from the mechanism that shutter as existing " rocker arm body-shutter and slow door " and slow door are driven simultaneously.In addition, this practicality is new
Type is the transmission that shutter sliding block is realized using movable pulley principle to slow door sliding block.It is with the first steel wire rope and first pulley
Example：One end of first steel wire rope is connected to the position with car frame geo-stationary, and the end is the fixing end of the first steel wire rope,
After bypassing first pulley, the other end of the first steel wire rope is connected to shutter sliding block, and with shutter slide block movement, the end is the first steel wire
The movable end of rope.A drive mechanism for movable pulley principle is so just constituted, now first pulley is movable pulley.In shutter
When sliding block makees the motion of enabling direction, shutter sliding block will involve the movable end of the first steel wire rope, it can be seen from movable pulley principle, now
The position of first pulley will change, and then the slow door sliding block where first pulley is also just driven, and then realize fast
Transmission of the door sliding block to slow door sliding block.Shutter sliding block closes the door direction when moving, and is also driven using movable pulley principle slow
Door sliding block close the door direction move, be now simply to be realized by second pulley and the second steel wire rope.
In addition, above-described first steel wire rope and the second steel wire rope can be two sections of steel cable.
It should be noted that the first steel wire rope and the cooperation of first pulley can also be replaced with into matching somebody with somebody for chain and chain drum
Close；Likewise it is possible to the cooperation of the second steel wire rope and second pulley to be replaced with the cooperation of chain and chain drum.As long as line in fact
The object for bearing certain pulling force of shape can serve as the substitute of the first steel wire rope and the second steel wire rope.
The one of which structure of above-described reciprocating action unit is：Including main Timing Belt, the first synchronizing belt gear and
Second synchronizing belt gear；The main Timing Belt, the first synchromesh gear, the second synchromesh gear collectively form conveying tape handler；
First synchronizing belt gear is driven by the motor.So, main Timing Belt the first synchronizing belt gear and the second synchronizing belt gear it
Between there will be two sections of sections for linear motion, a position of wherein one section for linear motion and shutter sliding block are connected to one
Rise, then after motor is rotated, shutter sliding block also will be for linear motion with the position of main Timing Belt.When motor is rotated backward, accordingly
Ground shutter sliding block makees reverse linear motion.First synchronizing belt gear is preferably adjustable with the distance of the second synchronizing belt gear,
So may insure that main Timing Belt is tightened.
Furthermore it is also possible to chain, the first chain drum and the second chain drum correspondence replace main Timing Belt, the first synchronizing belt gear and
Second synchronizing belt gear.
Furthermore it is also possible to replace main Timing Belt, the first Timing Belt tooth with belt, the first belt pulley and the second belt pulley correspondence
Wheel and the second synchronizing belt gear.
The utility model also provides a kind of car door mechanism, and it includes 2 symmetrically arranged car door machines as described above
Structure.
In the door mechanism of side opening door type, the movement rate for typically requiring slow door is the half of the movement rate of shutter,
So when shutter reaches position/pass in place, slow door also just reaches position/pass in place.By utilization movable pulley of the present utility model
The door mechanism of principle transmission, the movement rate of slow door is exactly just the half of the movement rate of shutter, fast completely without considering
Door and the problem of slow door movement rate matching, enormously simplify design link.
Car door mechanism of the present utility model have stable and reliable in work, compact conformation, be easily installed with maintenance, work it is quiet
The advantages of sound.When using in pairs, you can point two-fold door in composition.
