Here, Fig. 4 is the lateral plan that the complemental brake system 8 when observing from fracture detection bodies 24 sides of Fig. 3 is shown.In addition, Fig. 5 is the lateral plan that the complemental brake system 8 when observing with pole 22 sides from the engaging of Fig. 3 is shown.In addition, Fig. 6 is the lateral plan of engaging that Fig. 5 the is shown complemental brake system 8 when being positioned at braking position with pole 22.Be provided with the pars intermedia that pole 22 is used in engaging at turning cylinder 21 in rotation mode freely.Be connected with actuator 23 in the upper end that engages with pole 22.Engaging with pole 22 by the rotation centered by the axis of turning cylinder 21, at braking position (Fig. 6) be positioned at than braking position by displacement between the releasing position (Fig. 5) of top.When engaging was positioned at braking position with pole 22, as shown in Figure 6, engaging engaged with the tooth 16a of the peripheral part of ratchet 16 with the bottom of pole 22, thus, ratchet 16 is applied braking force, stops the rotation of ratchet 16.
When driving chain 14 fractures, fracture detection bodies 24 is come to be shifted to the detection position different with the holding position from the holding position that is positioned over driving chain 14 by the rotation centered by the axis of turning cylinder 21.In this example, the detection position is positioned at than position on the lower, holding position.In addition, in this example, when driving chain 14 fractures, fracture detection bodies 24 is displaced to the detection position by deadweight from the holding position.In addition, fracture detection bodies 24 has: boots 27, and it can slide at driving chain 14; And bar 28, the one end is connected with boots 27 in the mode that can rotate, and turning cylinder 21 is fixed in the other end.
As shown in Figure 3, by with arm 29 with respect to engaging with pole 22 in the axis direction staggered positions of turning cylinder 21, arm 29 is disposed in the mode of avoiding engaging the path that is shifted with pole 22.Projecting plate 30 is disposed at the axis direction and the position that engages with pole 22 coincidences at turning cylinder 21.Thus, press section material 25 is pressing fastened with pole 22 under only making projecting plate 30 and engaging the state that engages with pole 22.And, press section material 25 allow engaging with pole 22 to than the displacement of projecting plate 30 near the direction of braking position, and stop engaging with pole 22 to the displacements that approach the direction of releasing positions than projecting plate 30.
Fig. 7 is the lateral plan of the complemental brake system 8 of the Fig. 5 when driving chain 14 fractures are shown.Press section material 25 rotates integratedly with turning cylinder 21 and fracture detection bodies 24, therefore when driving chain 14 ruptures, with the detection bodies 24 that ruptures from the holding position to the displacement of detection position correspondingly, press section material 25 rotates centered by the axis of turning cylinder 21.Because to the displacement of detection position, press section material 25 is pressing fastened with pole 22 under projecting plate 30 and the state that engage with pole 22 engaging, makes simultaneously to engage with pole 22 to be shifted to braking position from the releasing position from the holding position for fracture detection bodies 24.
When engaging was shifted to braking position from removing the position with pole 22, the power that the application of force that press section material 25 utilizes the deadweight by the detection bodies 24 that ruptures to cause is resisted actuator 23 was shifted to the detection position from the holding position.That is, fracture detection bodies 24 has the power of opposing actuator 23 and quality that engaging is shifted to braking position when the portion's material 25 that is pressed is pressed with pole 22.
As Fig. 5～shown in Figure 7, at installation portion material 17, be equipped with via switch fabricated section 32 and remove detector switch (detecting device is removed in braking) 31, remove detector switch 31 and be used for whether engaging is positioned at the releasing position with pole 22 and detect.Remove detector switch 31 and be displaced to the engaging of removing position pole 22 operations, detect engaging thus and arrived the situation of removing the position with pole 22.
In addition, as shown in Figure 4, via switch fabricated section 34 fracture detector switch (chain break detector apparatus) 33 is installed at installation portion material 17, fracture detector switch 33 is used for whether fracture detection bodies 24 is positioned at the detection position and detects.The other end of being fixed in turning cylinder 21 at bar 28 is provided with operating portion 35, and this operating portion 35 is the projections with arcuation peripheral part.Operate fracture detector switch 33 by the operating portion 35 with the bar 28 that rotates of the displacement to the detection position of fracture detection bodies 24.In addition, fracture detector switch 33 is operated by operating portion 35, detects fracture detection bodies 24 thus to the displacement of detection position, thereby detects driving chain 14 fractures.
The control setup of escalator will be delivered to from the information of removing detector switch 31 and fracture detector switch 33 respectively.Control setup is according to the running of controlling escalator respectively from the information of removing detector switch 31 and fracture detector switch 33.
Then, action is described.When normal operation, carry out power supply to actuator 23 by the control of control setup.Thus, as shown in Figure 5, engaging is displaced to by actuator 23 with pole 22 and removes the position, and engaging is thrown off with respect to the engaging of ratchet 16 with pole 22.Thus, allow the rotation of chain gear apparatus 7.In addition, when normal operation, operate releasing detector switch 31 by engaging with pole 22, thus, the applying of confirming as chain gear apparatus 7 by control setup of braking force is disengaged.In addition, when normal operation, fracture detection bodies 24 is kept the state that is positioned over driving chain 14, has avoided the operation to fracture detector switch 33, thus, confirms as driving chain 14 by control setup and does not rupture.
When normal operation, if by the control of control setup the driving machine sprocket wheel 10 of driving machine 6 is rotated, then driving chain 14 is positioned over the state of driving chain 14 around movement with boots 27.Thus, main shaft 11, drive sprocket 12, top ladder sprocket wheel 13 and the rotation of ratchet 16 one, step 2 is synchronously mobile mutually with moving hand-rail 5.
For example when excessive or too small unusual of the speed that produces step 2 for some reason, the control by control setup stops the power supply to actuator 23.At this moment, the driving of also carrying out driving machine 6 by the control of control setup stops and the braking maneuver of the main brake device of driving machine 6.When the power supply to actuator 23 stopped, as shown in Figure 6, from removing displacement to braking position, engaging engaged with the tooth 16a of the peripheral part of ratchet 16 with pole 22 with pole 22 in engaging.Thus, ratchet 16 and chain gear apparatus 7 are applied braking force, to stop the rotation of ratchet 16 and chain gear apparatus 7.
On the other hand, when having produced driving chain 14 fractures unusual, fracture detection bodies 24 since deadweight be shifted to the detection position from the holding position, so that fracture detector switch 33 is operated.After detector switch 33 operated to fracture, the control by control setup stopped the power supply to actuator 23.At this moment, the driving of also carrying out driving machine 6 by the control of control setup stops and the braking maneuver of the main brake device of driving machine 6.After the power supply to actuator 23 stops, by action same as described above, ratchet 16 and chain gear apparatus 7 are applied braking force, to stop the rotation of ratchet 16 and chain gear apparatus 7.
In addition, even adjusting bad etc. causing under the situation that the power supply to actuator 23 do not stop owing to the bad or position of action of fracture detector switch 33, when fracture detection bodies 24 is shifted to the detection position, as shown in Figure 7, press section material 25 and fracture detection bodies 24 unitary rotation.Thus, engaging is pressed with pole 22, and portion's material 25 is pressed and from removing displacement to braking position, engaging engages with the tooth 16a of the peripheral part of ratchet 16 with pole 22.Thus, ratchet 16 and chain gear apparatus 7 are applied braking force, to stop the rotation of ratchet 16 and chain gear apparatus 7.
In such complemental brake system 8, the fracture detection bodies 24 that can be shifted integratedly and press section material 25 can be shifted with pole 22 independently with respect to engaging, when driving chain 14 fractures, be shifted to the detection position by the fracture detection bodies 24 that is positioned over driving chain 14, press section material 25 is pressing fastened with pole 22, and engaging is shifted to braking position from removing the position with pole 22, therefore do not need by connecting rod engaging to be connected respectively with press section material 25 with fracture detection bodies 24 with pole 22.Thus, can reduce number of components, and simplification and miniaturization that can implementation structure.In addition, owing to do not need by connecting rod engaging to be connected respectively with press section material 25 with fracture detection bodies 24 with pole 22, therefore can prevent because the generation of the remarkable action that the unfavorable condition of the displacement of connecting rod causes.Therefore, can carry out the braking maneuver of complemental brake system 8 more reliably.
In addition, fracture detection bodies 24 and press section material 25 can rotate centered by the axis of common rotational axis 21 integratedly, therefore further simplified structure, and can make the manufacturing of complemental brake system 8 become easy.
In addition, because fracture detection bodies 24 has: boots 27, it slides at driving chain 14; And bar 28, it is connected with boots 27 in the mode that can rotate, and can rotate centered by the axis of turning cylinder 21, therefore, even bar 28 with respect to the degree of dip variation of driving chain 14, also can make boots 27 keep fixing with respect to the sliding mode of driving chain 14.
In addition, because engaging can be rotated centered by the axis of turning cylinder 21 with pole 22, turning cylinder 21 is become for the common means of supporting engaging with pole 22, fracture detection bodies 24 and press section material 25.Thus, commonization of parts can be realized, and the miniaturization of complemental brake system 8, the simplification of structure and the reduction of cost can be realized.
In addition because press section material 25 has from top and the projecting plate 30 that engage with pole 22 engaging, therefore engaging with pole 22 to being positioned at when being shifted than releasing position braking position on the lower, can avoid engaging displacement with pole 22 portion's material 25 obstructions that are pressed.Thus, when the mode of pressing with the portion's material 25 that is not pressed with pole 22 in engaging is shifted to braking position separately, can engage usefulness pole 22 more reliably to the displacement of braking position.
In addition, owing to fracture detection bodies 24 has the quality that the power of resisting actuator 23 makes engaging be shifted to braking position when the portion's material 25 that is pressed is pressed with pole 22, therefore, when driving chain 14 fractures, can engage more reliably with the displacement of pole 22 to braking position, can carry out the braking maneuver of complemental brake system 8 more reliably.
In addition, in above-mentioned example, by engage to apply braking force to chain gear apparatus 7 with the tooth 16a of the peripheral part of ratchet 16, still being stuck the swivel that applies braking force with pole 22 also can be for for example drive sprocket 12 etc., and is not ratchet 16 with pole 22 in engaging.At this moment, also ratchet 16 can be set.At this moment, engage the shape that forms clamping drive sprocket 12 with pole 22, contact with drive sprocket 12 and clamping drive sprocket 12 with pole 22 by engaging, come drive sprocket 12 is applied braking force.
In addition, in above-mentioned example, when driving chain 14 fractures, fracture detection bodies 24 is shifted to the detection position from the holding position by deadweight, but also can for, to fracture detection bodies 24 application of forces, application of force direction is to make the fracture detection bodies 24 that is positioned over driving chain 14 to the direction of detection position displacement by force application spring (force body).If like this, then when driving chain 14 fractures, fracture detection bodies 24 is shifted to the detection position from the holding position by the applying power of force application spring.
In addition, in above-mentioned example, the present invention is applied to escalator, but the present invention also can be applied to moving sidewalk (passenger conveyors).
