Abstract
The invention relates to an additional brake of an automatic escalator. The additional brake comprises a transmission mechanism, a braking mechanism and a driving mechanism, wherein the braking mechanism is connected to one end of the transmission mechanism, and the driving mechanism is connected to the other end of the transmission mechanism. The transmission mechanism comprises a bendable flexible component. The flexible component is provided with an inner core and an outer casing pipe wrapping the inner core. One end of the inner core is connected with the braking mechanism, and the other end of the inner core is connected with a driving output end of the driving mechanism. When the driving mechanism acts, the driving output end transmits displacement to the braking mechanism through the inner core of the flexible component, and the braking mechanism is driven to act. By means of the additional brake, the mounting positions of the braking mechanism and the driving mechanism can be independent of each other; and meanwhile, by means of the additional brake, under the circumstance of emergency power-off, the braking effect can also be achieved.

In the case of electricity, when drive mechanism receives the instruction closing additional brake, the elastic force of back-moving spring is less than the work of drive mechanism
Firmly so that arrestment mechanism can be closed in time.
As preferably, described drive mechanism is hydraulic means, pneumatic means or electromagnet apparatus.Described drive mechanism provides
Active force drives drive output displacement to move, and drives inner core motion.
As preferably, described additional brake of escalator also includes additional brake action detection device, described driving
The drive output of mechanism is provided with trigger member and offsets with additional brake action detection device.Owing to trigger member is located at driving machine
In the drive output of structure, it is possible to along with drive output is moved, the additional brake action detection device position by trigger member
Put, it is judged that whether additional brake is in opens or closes.
Preferably, it is provided with lubricating oil between described trocar sheath and inner core.Lubricating oil reduces the resistance between trocar sheath and inner core
Power.
Compared with the existing technology, beneficial effects of the present invention is embodied in:
(1) drive mechanism used in the present invention includes bent compliant member so that arrestment mechanism and drive mechanism
Correct position can be selected, is independently come in both positions, do not limited by installation site.
(2) present invention is arranged with the back-moving spring of compressive state with arrestment mechanism in one end that inner core is connected so that automatically
Escalator auxiliary brake, under powering-off state, also can reach the effect of braking.

Detailed description of the invention
The present invention is further illustrated below in conjunction with embodiment and accompanying drawing.
Additional brake of escalator as shown in Figure 1, including compliant member 3, detent mechanism 1, electromagnet apparatus 2 and
Additional brake action detection device 4.Detent mechanism 1 and electromagnet apparatus 2 are separately mounted on truss 5.
As shown in Figure 2, detent mechanism 1 include the fixing rotatable lamella 12 in axle one end of ratchet 11 and ratchet 11 and with turn
The connector 13 that moving plate 12 is hinged, and ratchet 11 can withhold the gear of main drive wheel 6 when stretching out state.And compliant member
3 include trocar sheath 31 and in trocar sheath 31 can the inner core 32 that moves of displacement, wherein trocar sheath is all stretched out at inner core 32 two ends
31.Being provided with lubricating oil between trocar sheath 31 and inner core 32, trocar sheath 31 is the most compressible along diameter of axle direction, and can bend so that
Detent mechanism 1 and electromagnet apparatus 2 can select correct position.
Detent mechanism 1 is additionally provided with fixture 14, is located in fixture 14 by rotating hollow screw 33, hollow spiral shell
Nail 33 is threadably secured part 34 outer sleeve for connecting 31 through the part of fixture 14.Inner core 32 sequentially passes through trocar sheath 31, spiral shell
Stricture of vagina fixture 34, fixture 14 and hollow screw 33, fix with connector 13 and be connected.It is in the back-moving spring 35 of compressive state
Then being set in on the inner core 32 of connector 13 junction, one end offsets with connector 13, and the other end offsets with hollow screw 33.
As shown in Figure 3, this one end of electromagnet apparatus 2 is again provided with fixture 14 ', and hollow screw 33 ' is located in fixture
In 14 ', hollow screw 33 ' is threadably secured the other end of part 34 ' outer sleeve for connecting 31 through the part of fixture 14 '.And
The other end of inner core 32 then sequentially passes through trocar sheath 31, threaded fasteners 34 ', fixture 14 ', hollow screw 33 ', defeated with being provided with
The electromagnet apparatus 2 of shaft 21 connects.Output shaft 21 is provided with the trigger member 22 of inverted L shape, and trigger member 22 is installed additional brake
Action detection device 4, trigger member 22 offsets with the switch of additional brake action detection device 4.
When opening additional brake in the energized state, startup electromagnet apparatus 2 is driven inner core 32 by output shaft 21
Moving to detent mechanism 1 direction displacement, inner core 32 then can promote connector 13 that rotatable lamella 12 is rotated, and is in compression shape
The back-moving spring 35 of state can promote connector 13 equally, and both act on jointly, finally makes ratchet 11 stretch out prevention main drive wheel 6
Rotate.When output shaft 21 is to left dislocation, trigger member 22 can be driven to move so that additional brake action detection device 4 switchs
Open, it is judged that additional brake is in on-position.
When closing additional brake in the energized state, startup electromagnet apparatus 2 is driven inner core 32 by output shaft 21,
Inner core 32 the most reversely pulls connector 13 that rotatable lamella 12 is rotated, and finally makes ratchet 11 retract, and main drive wheel 6 can continue to
Rotate.When output shaft 21 displacement to the right, trigger member 22 can be driven to be returned to home position so that additional brake motion detection
Device 4 switch cuts out, then judge that additional brake is in non-brake state.
When escalator is in emergency power off, it is impossible to starting electromagnet apparatus 2, inner core 32 is not controlled by electromagnet apparatus 2
System.And the back-moving spring 35 being in compressive state will promote connector 13 to make rotatable lamella 12 rotate, finally make ratchet 11
Stretch out prevention main drive wheel 6 to rotate.
