Description
The present invention relates to a kind of slant type passenger conveyer; for example direction is mounted obliquely within upper strata floor disconnected from each other and the escalator between lower floor's floor under more than one; with a kind of moving walkways, and be particularly related to a kind of slant type passenger conveyer that each step can firm fixation between down period.
Up to now, slant type passenger conveyer is as the rotation of escalator all is, promptly drive a drive sprocket by gear reduction box with electrical motor, and then drive circularly one around drive sprocket and with drive sprocket pairing with the step chain on the movable sprocket, thereby drive the many steps that are connected in step chain.
And step is to be installed in brake equipment on the driving machine and to be stopped and maintain by handling one when shutting down.
In addition, when step stopped, just in case brake equipment is because fault or other are former thereby lose its effect, the passenger climbs up step may make step descend with regard to having applied load.For preventing this phenomenon, the escalator of the above-mentioned drive sprocket of a kind of lockable has been proposed, this technology is disclosed by open application (JPA) 59-97985 of Japanese Patent.
There is a problem in above-mentioned prior art, promptly directly locked owing to the major diameter drive sprocket, and itself structure is just very big, adding does not have the space to come around drive sprocket such lockout mechanism to be installed, so the escalator that reality is used adopts this mechanism that the volume of escalator is increased.
An object of the present invention is to provide a kind of slant type passenger conveyer, its step can be come stop and maintained when shutting down by a packaged plant.
Another object of the present invention provides a kind of slant type passenger conveyer, and it is simple in structure, and above-mentioned packaged plant also can install after elevator is delivered for use easily.
To achieve these goals, the invention provides and a kind ofly constitutes the device that retrains by rotating element engagement with the driving machine of slant type passenger conveyer, this passenger elevator comprises with upper and lower to being mounted obliquely within upper strata floor disconnected from each other and the mainframe on lower floor's floor, many being installed in the mainframe, be connected in a step chain, and the step that moves with step chain, one is installed in the mainframe, has a drive sprocket that is holding step chain on it, and drive the driving machine of step chain, and the brake equipment of the turning cylinder brake activation power of a pair of driving machine.
According to said structure, because the restraint device that it provides is and meshes at the rotating element of driving machine away from the minor diameter of sprocket wheel one side of the step chain of reeling, so the turning effort that acts on the restraint device diminishes, the result only needs just can stop and maintain step with a packaged plant.And, around this driving machine a sizable space is arranged, so this packaged plant also can be applicable to the elevator that delivered is used.

Fig. 4 is the scheme drawing of the control system of each equipment shown in Fig. 1 and 2;
Fig. 5 is the vertical sectional view of device on every side of expression one driving machine, and it has according to another restraint device of the present invention.
An embodiment according to slant type passenger conveyer of the present invention is described as follows referring to figs. 1 through 4.The slant type passenger conveyer here is an escalator, wherein, guiding many steps 3 that are connected on the step chain 2 end to endly, thereby circulating motion in a mainframe 1, to being mounted obliquely between the upper strata floor UF and the floor LF of lower floor disconnected from each other, step 3 is guided by the guide rail (not shown) that above-mentioned mainframe 1 is supporting this mainframe 1 with upper and lower.
Above-mentioned step chain 2, and is driven by drive sprocket 4 with on the movable sprocket 5 around a drive sprocket 4 and, and this two sprocket wheel is supported by last unit room 1A and following unit room 1B, and this two unit room is separately positioned on the both ends of mainframe 1.
In addition, handrail side panel 10 is arranged on the both sides of step along the moving direction of each end to end step 3, and the handrail bar 11 of motion is on the periphery of side plate and be supported, and handrail bar 11 synchronously is driven with step 3.
Above-mentioned upward unit room 1A and following unit room 1B are respectively by upper and lower ascending stair plate 12A and 12B capping.
On the other hand, driving machine 8 comprises an electrical motor 13 and a gear reduction box 14.The turning cylinder 16 of electrical motor 13 is connected in the input shaft of gear reduction box 14, and sprocket wheel 15 is installed on the output shaft of gear reduction box 14, and driving chain 7 is on sprocket wheel 15.
Also have, above-mentioned brake equipment 9 is mounted on the input shaft of gear reduction box 14.
Said gear drop-gear box 14 is a kind of so-called retarders that parallel to the axis, wherein, and input shaft and output shaft layout parallel to each other, and adopt helical wheel.
Said structure is a kind of structure of common escalator.The special character of present embodiment is, a restraint device is provided, and by intermeshing, thereby retrains its rotating element with respect to the fixed part of driving machine 8.That is to say, restraint device is made up of a ratchet wheel 17 on the turning cylinder 16 that is arranged on electrical motor 13 and a claw 18 on fixed parts, and when step 3 stopped, even brake equipment 9 is malfunctioning, ratchet wheel and claw also can stop and maintain step 3 by intermeshing.
Yet, be under the situation of an axle at the turning cylinder 16 of electrical motor 13 and the input shaft of reducing gearbox 14, will connect without any need for coupler, and special-purpose ratchet wheel should be provided.In this case, ratchet wheel 17 can be set,, with new method this ratchet wheel be set and need not reserve bigger space as long as distance and this root axle between electrical motor 13 and the gear reduction box 14 are passable.
The other end of L shaped claw 18 is connected in an electromagnetic actuator device 21 that is used to handle claw 18.Electromagnetic actuator device 21 is fixed on the casing of said gear drop-gear box 14, and comprises a coil (not shown) that can produce electromagnetic force by switching on, a power-actuated movable core 22 of electromagnetism and a returning spring 18S who is used for driven movable core 22 is back into initial position by generation.Movable core 22 has an other end bonded assembly free end by pin and L shaped claw 18.And, the engaging piece 19 that the thrust that returning spring 18S produces makes L shaped claw 18 1 end places always with ratchet wheel 17 on the tire engagement, and above-mentioned coil can produce magnetic force, drives movable core to making the out-of-gear direction motion of engaging piece 19 and tire 17c.
In addition, a search switch 23 is fixed on the casing of gear reduction box 14, and this switch 23 is to be contained in that side opposite with the engaging piece 19 of claw 18 1 ends.
In said structure, when escalator was shut down, electrical motor 13 was cut off power supply, and electrical motor 13 is subjected to the braking of brake equipment 9 by the input shaft of gear reduction box 14.Like this, brake driving machine 8, and then stop to move of step 3 by driving chain 7 and step chain 2.
At this moment, suppose that the reduction ratio between driven sprocket 6 and the sprocket wheel 15 is 1/4 approximately, and the reduction ratio between sprocket wheel 15 and the turning cylinder 16 is 1/16 to 1/17 approximately, then total reduction ratio is 1/64 to 1/68.Suppose that the passenger's load that trends towards making driven sprocket 6 to rotate is F, the turning effort F ' that acts on so on the ratchet wheel 17 on the turning cylinder 16 is F/64 to F/68 (F '=F/64 to F/68), and this is very little.Therefore, ratchet wheel 17 and claw 18 can be done lessly.
Like this, when step 3 was braked device 9 and stops, claw 18 also was meshed with tire 17c on the ratchet wheel 17 with its engaging piece 19 simultaneously.Therefore; even there are many passengers to take advantage of on staircase above the braking potential of brake equipment 9; even perhaps brake equipment 9 breaks down and loses braking potential but still have the passenger to take advantage of in the above between the staircase down period; step 3 can not move down yet, because the turning cylinder of driving machine 8 is subjected to the constraint of claw 18.
Then, when above-mentioned escalator when stopped status issues out operating order, controller 24 makes the coil electricity of electromagnetic actuator device 21 and produces electromagnetic force, it attracts movable core 22 to overcome the pressure of returning spring 18S.Owing to inhale moving movable core 22, the other end of L shaped claw 18 rotates around the bolster as the center, and the engaging piece 19 of L shaped claw 18 1 ends separates and jump out of mesh with ratchet wheel 17.Like this, when claw 18 turns to when making the position that the engagement between engaging piece 19 and the tire 17c breaks away from fully, one end of L shaped claw 18 touches search switch 23, give brake equipment 9 energisings after search switch is touched and make it discharge braking force, thereby make electrical motor 13 startings and begin to drive escalator.
See the situation that the staircase that will make running stops again.When sending when instruction of shutting down, by controller 24 electrical motor 13 is reduced speed now, just some time when electrical motor 13 stops or slightly, stop to power with the generation braking force to brake equipment, the turning cylinder of driving machine 8 is stopped and is maintained thus.When brake equipment 9 produced braking force, in other words, in brake equipment 9 outages, the coil of electromagnetic actuator device 21 also was de-energized.Because electromagnetic actuator device 21 coil blackouts, the magnetic force of coil disappears, and no longer attracts movable core 22, thereby passes through the thrust of returning spring 18S, make the other end of the L shaped claw 18 of movable core 22 pushings of 21 li of electromagnetic actuator devices, the bolster 20 that claw 18 is made to the center rotates.The rotation of claw 18 makes the engaging piece 19 of one end near ratchet wheel 17, and meshes with tire 17c, thus the turning cylinder of constraint driving machine 8.
In the above description, the coil of electromagnetic actuator device 21 is to cut off the power supply when brake equipment 9 produces braking force, and thus, the turning cylinder of driving machine 8 is restrained.In this case, if brake equipment 9 and electromagnetic actuator device 21 cut off the power supply, do not have any problem when electrical motor 13 stops.
Yet if slightly preceding some time outage of brake equipment 9 before electrical motor 13 stops, even applied braking force so, escalator also can be owing to inertia moves some distances.Therefore; in this case, when giving electromagnetic actuator device 21 outages such danger may take place, promptly ingear produces constantly and shuts down impact between engaging piece 19 and tire 17c; engaging piece 19 and tire 17c are damaged, and device damage around making gear reduction box 14 etc.
Make the coil delay cut-off of electromagnetic actuator device 21 with a time delay device, just can eliminate above-mentioned shortcoming.That is to say, provide a timer 25 just passable to controller, make that this timer is that benchmark works with a ct-off signal, make the outage of electromagnetic actuator device 21 occur in (this delay time should be longer up to the time that escalator stops than producing braking force) after the brake equipment 9 outage back certain hours.To escalator stop to confirm, the single-revolution coder on for example available turning cylinder that is installed in electrical motor 13, its pulse offers controller 24 as acknowledgment signal.
By such timer 25 is set, after the inertia motion that just can make engagement between engaging piece 19 and the tire 17c occur in escalator stops, so just can preventing the damage of locking apparatus.
Moreover above-mentioned time delay device is a kind of electronic delay device by controller 24 controls, and still, it also can be a kind of mechanical type time delay device as shown in Figure 5.That is, it is to constitute like this: be connected in the other end of L shaped claw 18 with an one-way damper 27 by its bar 28, and this claw is connected in the movable core 22 of electromagnetic actuator device 21 by a pin.27 of one-way dampers have shock damping action in one direction, when passing through the other end of the moving claw 18 of movable core 22 suctions behind the coil electricity of electromagnetic actuator device 21, damper does not have shock damping action, so can make movable core 22 quick travel, otherwise, when the coil blackout of electromagnetic actuator device 21, built-in returning spring pushing movable core 22, make it outstanding and when promoting the other end of claw 18, damper has shock damping action, thereby it is slowly moved.Owing to be the other end that slowly pushes back claw 18, can spin out engaging piece 19 and enter the engagement time before with tire 17c, the result is that engaging piece 19 and tire 17c are just intermeshed after the inertia motion of escalator stops.By adjusting the time of microinching, microinching was finished after the definite time after brake equipment 9 produces braking force, as mentioned above, just can prevent the damage of installing on every side.
More than explanation certainly, also is applicable to the moving walkways that tilts to install at escalator.
As mentioned above, according to present embodiment, provide a kind of rotating element and engagement between the fixed part to set up the restraint device of constraint by driving machine, like this, step can be come stop and maintained when stopping by a little device, and this plant bulk is very little, and is that rotating element around driving machine is provided with, like this, it can be applied to install ready passenger elevator at an easy rate.
As mentioned above, according to the present invention, can stop with the step that a packaged plant will stop and maintaining, slant type passenger conveyer can use on this structure and simply install, and this device can be applied to the elevator of Dd at an easy rate.
