门系统
Door system
门系统作为整部电梯的一个子系统，是电梯的一个重要组成部
分。它是电梯的使用者进出
电梯的通道，是电梯乘客使用电梯首先接触的电梯部件，它的
质量好坏，能够从感官上直
接影响电梯的使用者对整个电梯的质量评估。
As
an
integrated
and
important
part
in
lift,
door
system
is
used
as
a
passage
for
passengers.
It
is
the
first
unit
passengers
will
encounter,
so
its
quality
has
a
direct
impact on the whole evaluation of the
lift.
如前所述，电梯门主要有两类，
滑动门和旋转门<
/p>
，目前普遍采用的是滑动门。旋转门在小
型公寓用得较多，厅门在
轿厢停站后拉（推）开，当轿厢不在层站时厅门锁住。这种门几
乎不占用井道空间，特别
适用于无轿门电梯。
From above
mentioned, there are two types of doors: sliding
door and rotary door and
the former is
frequently used.
For rotary
door which is usually used in small apartments,
landing door is pulled or pushed after
car stops on landing; landing door is locked if
car is
not on landing.
It hardly occupies any well space, so
rotary door is especially applicable
to
life without car door.
滑动门按
其开门方向又可分为
中分式、旁开式和直分式三种
。
According to its door open
direction, sliding door can be classified into
central-parting,
partial-opening
and
vertical bi-parting
door
。

轿门系统
Car door
system
轿门系统由轿门头、门吊板、轿门、安全触板
(
或光幕
)
等部件构成。见图
6-1
Car door is
composed of car door head, door sling board, car
door and safety edge (or
light
curtain), as shown in figure 6-1.
轿门头由
3mm
钢板压制，固定在轿厢顶前部<
/p>
，上面装有导轨，轿门就在此导轨的支撑与导
向下运行。
Made of 3mm steel board, car
door head is fixed in the front of car top.
On door head is
mounted guide rails; supported and
guided by rails, car door is running.

轿
门吊板起悬吊轿门的作用。在门吊板的上面装有两组悬吊滚轮，支撑在导轨上，在悬吊
滚
轮的带动下，轿门沿导轨作滑动运行。在悬吊滚轮的下方，由两组装有偏心轴的锁紧滚
轮，它卡在导轨的下侧，
可通过调整偏心轴来调整锁紧滚轮同导轨下侧的间隙，以防止门
吊板从导
轨上脱落。
Car door sling board
is used to hoist car door.
On sling board are mounted two groups
of sling rollers to support rails.
Driven by sling rollers,
car door will slide along guide
rails.
Below the sling roller are
two groups of lock rollers with deflecting axis,
which are
fastened below guide rails;
the gap between lock roller and lower space of
guide rails

can be adjusted by means of deflecting
axis, to prevent sling board from falling out of
rails.
普通钢轿门由
1.5mm
冷轧钢板压弯成形，背后加焊横筋组成
。也可根据用户及轿厢装潢要
求，
在普通钢轿门上粘
0.7mm
厚发纹不锈钢或镜面不锈钢板
。<
/p>
Ordinary steel car door is
made of 1.5mm cold reduced steel board, with back
welded.
According
to
customers’
request
and
car
decoration, ordinary
steel door can be
stuck
with 0.7mm thick-hair-
line stainless steel or glass stainless steel
boards.
轿门也可以直接用
1.5mm
的不锈钢制成。
Car
door can also be made of 1.5mm stainless steel.
门安全触板是安装在轿门上的安全部件。在中分门电梯的轿门
上，可根据用户的要求安装
双安全触板或单安全触板。安装调整好的安全触板外边，总是
探出门边
26mm
。在轿门关闭
时，若
触板碰到乘客或物品，触板的开关闭合，给开门机信号，使轿门重新打开，从而起
到安全
保护的作用。
As safety part, door
safety edge is mounted on car door.
Central-parting door can be
equipped with double safety edge or
single safety edge, according to customers’
request.
Exterior hem of
safety edge is always protruding door edge by
26mm.
When car door is
closing, if safety edge touches
passengers or object, safety edge switch will
close, giving
off door-open signals,
making car door re-open, thus playing a role in
protecting.
现代电梯大多用光幕代替安全触板
起保护作用
。
Most
modern lifts are equipped with light curtain to
replace safety edge.

门机
Door operator
门的关闭、开启的动力源是门电动机，通过传动机构驱动轿门
运动，再由轿门带动厅门一
起运动。
As power provider for closing and
opening door, motor will drive car door to move,
which will
drive landing door to move.
根据电梯的使用要求可以选择适当的传动系统，
例如
OTIS
的
MRDS
门机采用齿轮传动，
而
蒂森的
F5
门机采用的是齿带传动等
。
Driving system can be chosen
according to lift application.
For instance, OTIS MRDS
door
operator
adopts

driving,
while
Thyssen
F5
door
operator
does

门机一般设在轿
厢顶部，根据开关门方式，门机可设在轿顶前沿中央或旁侧。
Usually mounted on car top, door
operator can be located in the center or side of
the
front of car top according to door
opening modes.
门机的种类有直流电机、交流电机
，
调速方式有调压调速、变频调速
等。
Door

is
classified
into

门机由于垂直驱动轴而垂直安装在门头上，
轿
门由齿带操纵完成往复运动，因此省去了所有的附加操作元件。

belt, car door is recurrently moving,
thus
obviating auxiliary
components.
F5
门机采用无齿轮交流异步电动机
，变频器控制，其工作原理为，
电子控制装置依据运行
时间曲线
计算门的位置
，
给出最佳运行速度
。<
/p>
门控制器给出特定运行时间曲线控制门的运
动
。运行时间曲线没有振动的限制，所有的运行时间参数取决于开门、关门、强迫关门和
再开门操作的调整。
Adopting gearless
AC asynchronous motor, F5 door operator is
controlled by frequency
inverter.
The
mechanism
of
F5
door
operator
is
as
follows:
electrically
controlled
device
will
determine
door
position
based
on
running
time
curve,
outputting
optimum
running
speed.
Door
control
will
output
specific
running
time
curve
to
control
door
movement.
Running time curve is not limited by
vacillation; all running time parameters
are decided by the settings of door-
open, door-close, door-nudge and door-reopen.
门机自动检测门是否到达终端位置并发出各自的终端位置信号
给电梯控制系统，然后在各
自的控制信号作用下给出可微调的终端位置转矩。
Door
operator
will
automatically
test
whether
door
has
reached
terminal
position
and
give
off
individual
terminal
position
signal
to
lift
control
system,
later
output
terminal
position torque which can be find-tuned
under the effect of individual control signals.
门保持在一定的终端位置可调节范围内，给电梯控制系统的终
端位置信号保持有效，不考
虑相应信号是否发出，这种情况就好像终端位置开关一样。<
/p>
Door
will
remain
in
adjustable
range
of
definite
terminal
position.
Terminal
position
signals
to
lift
control
system
will
remain
effective
no
matter
whether
corresponding
signals have
been
sent
or not.
This
circumstance
is as
the
same as
that
of
terminal
position switch.
开门和关门运行时间曲线如图

所示。

In figure 6-3 is shown door open
and door close time curve.
