The specific embodiment
Describe in detail according to the inverted running be used to preventing escalator of the present invention some preferred implementations with the auxiliary braking equipment of overrunning now with reference to accompanying drawing.
With reference to Fig. 3 to Fig. 8, control is used for preventing that the inverted running of escalator and the method for the auxiliary braking equipment of overrunning from may further comprise the steps: confirm that whether escalator is in up or down motion; If the contrarotation detecting sensor 31 of escalator, then utilizing at upward movement detects whether contrarotation of escalator, if escalator is moving downward, then utilize the detecting sensor 32 of overrunning to detect the downstream rate of escalator; If the downstream rate of the escalator that is detected by the detecting sensor 32 of overrunning surpasses the first specified speed, then to the vital circuit supply shutoff signal of main control panel 20 to cut off to the electric power supply of CD-ROM drive motor 21 and to activate main brake device 25; And if detect the inverted running of escalator or if the downstream rate of the escalator that detected by the detecting sensor 32 of overrunning surpasses than the first specified speed the second specified speed faster by contrarotation detecting sensor 31, then activate emergent stopping complemental brake system 40 by operational relay plate 45.
In this respect, preferably, emergent stopping complemental brake system 40 is hydraulic brake systems, and this hydraulic brake system operates to utilize mechanical force to apply braking to the axle drive shaft 35 of escalator by relay board 45.
The equipment of carrying out said method comprises: main control panel 20, described main control panel are used for being configured in main brake device 25 in the CD-ROM drive motor 21 to the CD-ROM drive motor 21 supply electric power of escalator and actuating; The hand of rotation of the escalator S. A. 30 that contrarotation detecting sensor 31, described contrarotation detecting sensor are connected for detection of the output shaft with CD-ROM drive motor 21; The detecting sensor 32 of overrunning, the described rotative speed of detecting sensor for detection of escalator S. A. 30 of overrunning; Emergent stopping complemental brake system 40, described emergent stopping complemental brake system are used for utilizing mechanical force to stop the rotation of escalator S. A. 30; And control unit 10, described control unit is used for based on determining the appearance of abnormal condition from the signal of contrarotation detecting sensor 31 and detecting sensor 32 supplies of overrunning and to main control panel 20 or be sent to relay board 45 and transmit signals, to supply electric power to emergent stopping complemental brake system 40.
Emergent stopping complemental brake system 40 comprises the first brake unit, and described the first brake unit is installed in the central portion of escalator S. A. 30, applies braking force with the central portion to this escalator S. A..This first brake unit comprises brake disc 41 and hydraulic tongs 42, wherein, brake disc 41 is fixed to escalator S. A. 30, hydraulic tongs 42 is by from the electric power operation of relay board 45 supply and be designed to exert pressure to two opposed surface of brake disc 41 simultaneously, to suppress thus the rotation of brake disc 41.Preferably, hydraulic tongs 42 can be installed in symmetrically in paired mode the two opposite sides of brake disc 41.
As shown in Figure 5 and Figure 8, brake disc 41 is disposed between the drive sprocket 36 of the two opposite sides that is installed on escalator S. A. 30.Particularly, brake disc 41 is designed to be installed in a fixed manner in the central portion between relative drive sprocket 36.
Alternatively, as shown in Figure 10 and Figure 11, brake disc 41 can be arranged on arbitrary or both places of two drive sprockets 36 of the end that is installed in escalator S. A. 30.
As shown in Figure 7, hydraulic tongs 42 is provided with caliper 42a and a pair of brake shoe 42b, and wherein, described caliper is configured to local around brake disc 41, described a pair of brake shoe is installed in the two opposite sides of caliper 42a, and brake disc 41 is plugged between the brake shoe 42b.
Along with the hydraulic fluid of fluid pump 44 is introduced into through fluid passage 42e, piston 42c moves forward, with the side of extruding brake shoe 42b.Then, brake shoe 42b and brake disc 41 form wipe contact.At this moment, the brake shoe 42b that is arranged on opposition side also with brake disc 41 close contacts.
As a result, two brake shoe 42b form wipe contact with the opposed surface of brake disc 41 simultaneously.Therefore, brake disc 41 applies unexpected emergency braking to escalator thus owing to high friction force stops its rotation.
Therefore, even when mains power failure, the hydraulic fluid of fluid pump 44 also can be supplied to hydraulic tongs 42 constantly.Therefore, even when power supply is cut off, also can be to the escalator apply the emergency brake.Can keep emergency braking condition by energy storage 44c.
In other words, though applying when electric power be cut off under the state of braking after energy storage 44c also keep the pressure of hydraulic fluid, thereby guarantee that brake unit continues to apply braking.
Referring again to Fig. 3 to Fig. 5, expectation contrarotation detecting sensor 31 and the detecting sensor 32 of overrunning are designed to detect the rotation of brake disc 41.
Emergent stopping complemental brake system 40 is arranged on the central portion of escalator S. A. 30, accurately applies braking with the central portion to escalator S. A. 30.This is so that can suppress equably the rotation of whole escalator S. A. 30, and this has maximized emergent stopping efficient.Therefore, when heavy escalator during with the excessively high speed motion or along contrarotation, can effectively apply unexpected emergency braking.
Because emergent stopping complemental brake system 40 is arranged on the central portion of escalator S. A. 30, therefore emergent stopping complemental brake system 40 can be installed in the situation of the installation component that any separation is not provided.Therefore, very simple and emergent stopping complemental brake system 40 easily is installed, this is so that can be installed in emergent stopping complemental brake system 40 in the existing escalator.
In common situation, single emergent stopping complemental brake system 40 is installed in auxiliary braking equipment.Yet, as shown in Figure 9, based on deceleration loading two or more emergent stopping complemental brake systems can be set.
In this case, apply braking by a plurality of parts to escalator S. A. 30, can maximize the quick emergent stopping effect of escalator S. A. 30.
In the situation that is provided with a plurality of emergent stopping complemental brake systems 40, preferably, emergent stopping complemental brake system 40 is installed with respect to the central portion of escalator S. A. 30 symmetrically with spaced relation.
As shown in Figure 10 and Figure 11, drive sprocket 36 comprises the first sprocket wheel and second sprocket wheel of two opposite ends that are attached to escalator S. A. 30.Can also comprise near one the second brake unit that is installed in the first sprocket wheel and the second sprocket wheel according to the inverted running for preventing escalator of the present invention and the emergent stopping complemental brake system 40 of overrunning.Emergent stopping complemental brake system 40 can be installed on these two sprocket wheels.
Adopt aforesaid structure, be used for preventing the inverted running of escalator and hand of rotation and the rotative speed of the auxiliary braking Equipment Inspection escalator of overrunning.When escalator rotated along contrarotation or with the speed higher than specified speed, auxiliary braking equipment activated the emergent stopping complemental brake system, to stop the operation of escalator.
If if escalator in upward movement suddenly descending and contrarotation detecting sensor 31 detect the contrarotation of brake disc 41, then control unit 10 is determined to occur abnormal condition and is provided " danger signal " to relay board 45 in escalator.
At this moment, piston 42c moves forward by the hydraulic fluid that is applied to pressure acceptance division 42d, pushes thus the side of brake shoe 42b.Then, brake shoe 42b more forms wipe contact near brake disc 41 and with brake disc 41.The brake shoe 42b that is arranged on opposition side also contacts with brake disc 41.
Therefore, two brake shoe 42b form wipe contact with the opposed surface of brake disc 41 simultaneously.As a result, brake disc 41 is owing to the increasing friction force that applies to it stops.
When brake disc 41 stopped its rotation, the axle drive shaft 35 that is provided with brake disc 41 also stopped, thus so that escalator stops its operation.
If passenger's safety is finished and guaranteed to emergent stopping, if perhaps removed " reverse run signal " or " signal of overrunning " from contrarotation detecting sensor 31 or the detecting sensor 32 of overrunning, then control unit 10 does not produce " danger signal ".
Then, if " danger signal " is removed, then relay board 45 stops the operation of fluid pump 44.When fluid pump 44 stopped its operation, the pressure that is applied to the pressure acceptance division 42d of piston 42c was released.
Be removed if be applied to the pressure of piston 42c, then the squeese pressure that is applied on the brake shoe 42b of piston 42c also is released.Therefore, the friction contact load of brake disc 41 is removed.As a result, brake disc 41 begins rotation and allows escalator to restart its operation.
The pressurization hydraulic fluid that acts on the piston 42c turns back to fluid reservoir 44a via fluid passage 42e.
Referring again to Fig. 3 to Fig. 8, when brake disc 41 rotated quickly than specified speed, the detecting sensor of overrunning 32 detected this situation and to control unit 10 output signals.If brake disc 41 with " the first specified speed " that surpass specified speed (for example, to surpass 120% speed of specified speed) rotation, thus then control unit 10 transmits signals with the operation that stops CD-ROM drive motor 21 and activates the rotation that main brake device 25 suppresses output shafts 23 to main control panel 20.Therefore, the axle drive shaft 35 that is connected to output shaft 23 stops its rotation, stops thus the operation of escalator.
In the situation that the driving chain with output shaft 23 and axle drive shaft 35 interconnection disconnects, even main brake device 25 works, axle drive shaft 35 also will can not stop and continuing rotation.Because accelerate, the brake disc 41 that is arranged on the axle drive shaft 35 rotates fasterly.
If brake disc 41 is with than " the first specified speed " higher " second specified speed " (namely, to surpass 140% speed of specified speed) rotation, then control unit 10 provides signal to relay board 45, activating emergent stopping complemental brake system 40, thereby stop the operation of escalator.
Therefore, when the downstream rate of escalator in the situation about moving downward increased for some reason and fast, the operation of escalator was stopped immediately, and this is so that can prevent from freely falling the safety misadventure that causes by escalator.
Although above describing preferred implementations more of the present invention, the present invention is not limited to these embodiments.It should be understood that in the scope of the present invention that those skilled in the art can limit in the claims and suitably revise these embodiments.
