Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are merely examples, and the scope of the present invention is not limited thereto. Further, the components in the following embodiments also include components that are easily conceivable by those skilled in the art or that are substantially the same.
In the present embodiment, an escalator 100 will be described as an example of a passenger conveyor that operates by moving a plurality of steps connected in a loop around (in a circulating manner). As shown in fig. 1, the emergency brake device 1 of the escalator according to the embodiment is provided in an escalator 100. The escalator 100 is installed in a building (also referred to as a building), and transports passengers and the like by crossing one floor (hereinafter, referred to as a lower floor) of the building and another floor (hereinafter, referred to as an upper floor) above the lower floor. The emergency brake device 1 is an example of an emergency brake device for a passenger conveyor.
The escalator 100 mainly includes a truss structure frame 110, a plurality of steps 120, and a balustrade 130. A frame (not shown) and a drive mechanism of the escalator 100 are disposed inside the truss structure frame 110.
The drive mechanism 100a of the escalator 100 mainly includes a motor 105 as a drive source, a speed reducer 106, a drive chain 112, a drive wheel 113, a driven wheel 114, and a step chain 115. The motor 105 is provided on the upper floor side. A reducer 106 is attached to an output shaft of the motor 105. The drive chain 112 is formed in an endless shape, and is hooked on a small sprocket 111 of the speed reducer 106 and a large sprocket 116 of the drive wheel 113. The drive chain 112 circulates around the drive wheel 113 and the small sprocket 111 of the reduction gear 106 by the drive force of the motor 105 transmitted through the reduction gear 106, thereby rotating the drive wheel 113. That is, the drive chain 112 transmits the driving force of the motor 105 transmitted via the reduction gear 106 to the drive wheel 113. The rotational axis 117 (fig. 2) of the small sprocket 111 and the rotational axis 118 (fig. 2) of the large sprocket 116 are parallel. The diameter of large sprocket 116 is larger than the diameter of small sprocket 111, and the number of teeth of large sprocket 116 is larger than the number of teeth of small sprocket 111. The small sprocket 111 is an example of the 1 st sprocket, and the large sprocket 116 is an example of the 2 nd sprocket.
The escalator 100 operates by driving a step chain 115 that is hooked between a driving wheel 113 and a driven wheel 114 to move a plurality of steps 120 connected in an endless manner.
When the escalator 100 is operated in the descending direction, the steps 120 adjacent to each other in the traveling direction among the plurality of steps 120 horizontally protrude from the truss structure frame 110 at the upper landing (upper-floor landing 101). Further, at the upper transitional bent portion, the step difference between adjacent steps 120 is enlarged, and the plurality of steps 120 transits into a staircase shape. Further, the plurality of steps 120 descend in a staircase shape at the intermediate inclined portion. Further, at the lower transitional portion, the step difference between adjacent steps 120 is reduced, and the plurality of steps 120 transits to a horizontal shape. Further, at the lower landing entrance (lower-floor landing entrance 102), the plurality of steps 120 are again horizontal and enter the truss structure frame 110. Further, the plurality of steps 120 are inverted upward after entering the truss structure frame 110, and are raised horizontally on the return path side. Further, the plurality of steps 120 are inverted again and extended from the truss structure frame 110 at the upper floor landing entrance 101. The escalator 100 that is moving in the ascending direction operates in the reverse direction to the above-described operation. In this way, the steps 120 extend out of or into the truss structure frame 110 so that the step surface of the upper surface on which the user rides is horizontal at the upper and lower landing entrances 101 and 102.
The escalator 100 includes a pair of balustrades 130 on both sides in the traveling direction of the steps 120. The balustrade 130 is mainly composed of a skirt guard (not shown), an inner cover 131, a glass 132, and a handrail 133. The skirt guard plates are provided so as to be adjacent to both sides in a direction (width direction) orthogonal to the traveling direction (descending direction and ascending direction in which the escalator 100 operates) of the plurality of steps 120 and so as to span between the upper-floor-side landing entrance 101 and the lower-floor-side landing entrance 102. An inner cover 131 is attached to the upper side of the skirt guard. A glass 132 is attached to the upper side of the inner cover 131. The handrail belt 133 is movably fitted to a handrail guide (not shown) attached to the outer periphery of the glass 132. The escalator 100 is constituted by: the handrail 133 of the balustrade 130 is moved around by a handrail drive chain (not shown) according to the traveling direction and the traveling direction of the steps 120.
The emergency brake device 1 is provided in the drive mechanism 100a of the escalator 100, and prevents the steps 120 from moving around by preventing the rotation of the drive wheel 113 when the drive chain 112 extends by a predetermined amount or more, for example, when the drive chain 112 is slack. The emergency brake device 1 is explained in detail below.

Fig. 8 is a side view of a bearing of a fixing portion in the emergency brake device for a passenger conveyor according to the embodiment.
As shown in fig. 2, the emergency brake device 1 includes a ratchet 11, a pawl member 12, a detection portion 13, and a coupling shaft 14.
The coupling shaft 14 is provided along the axial direction of the rotary shaft 118 of the large sprocket 116. In other words, the coupling shaft 14 is disposed parallel to the rotation shaft 118 of the large sprocket 116. The connecting shaft 14 is rotatably supported by a pair of beam members 141 of the truss structure frame 110 via a support member 142. The connecting shaft 14 is an example of the 1 st connecting shaft.
The pawl member 12 is fixed to a portion of the coupling shaft 14 facing the ratchet 11. The claw member 12 extends from the coupling shaft 14 toward the radial outside of the coupling shaft 14. The pawl member 12 is provided in a state of being separated from the ratchet 11. The pawl member 12 rotates in a direction toward the ratchet 11 integrally with the coupling shaft 14 from a state (standby position, initial position) separated from the ratchet 11 and hooks on the ratchet 11, thereby preventing the rotation of the ratchet 11. Thereby, the rotation of the large sprocket 116 is prevented.
As shown in fig. 2 and 3, the detection unit 13 includes an arm 15, a contact body 16, and a connection unit 17. The detection unit 13 is provided at a portion of the coupling shaft 14 facing the drive chain 112.
The arm 15 is fixed to a portion of the coupling shaft 14 facing the drive chain 112. That is, the arm 15 is fixed to the connecting shaft 14 with a space from the claw member 12. The arm 15 extends from the coupling shaft 14 toward the radial outside of the coupling shaft 14. A contact body 16 is coupled to the distal end portion 15a of the arm 15 via a coupling portion 17. The arm 15 rotates integrally with the connecting shaft 14. The arm 15 is formed of a single piece (member).
The contact 16 is mounted on the drive chain 112. The contact body 16 presses the drive chain 112 downward by its own weight. The drive train 112 slides relative to the contact 16. The contact body 16 also serves as a vibration suppressing member that suppresses (suppresses) vibration of the drive train 112. The contact body 16 is also referred to as a vibration suppressing member or a vibration suppressing shoe.
As shown in fig. 4 to 6, in detail, the contact body 16 includes a base member 20 and a contact member 21. The base member 20 has walls 20a, 20 b. The wall 20a expands in a direction orthogonal to the axial direction of the coupling shaft 14. The wall 20b extends from an end of the wall 20a on the drive chain 112 side in the axial direction of the connecting shaft 14 and is positioned above the drive chain 112. The base member 20 is made of, for example, a metal material.
The contact member 21 is fixed to the lower surface of the wall 20b, and is placed on the outer peripheral portion of the drive chain 112. That is, the contact member 21 contacts the outer peripheral portion of the drive chain 112.
As shown in fig. 6, the contact 16 is provided with a hole 16 c. Specifically, the wall 20a is provided with a hole 16 c. The hole 16c penetrates the wall 20a in the thickness direction of the wall 20a, i.e., in the axial direction of the coupling shaft 14. The hole 16c is an arc-shaped long hole protruding in a direction away from the coupling shaft 14. The hole 16C has an arc shape around the center C3. That is, the center C3 is the center of the circular arc. The longitudinal direction of the hole 16c intersects (e.g., is orthogonal to) the axial direction of the coupling shaft 14. The distance between the center 16ca and the center C3 of the hole 16C is the same as the distance between the rotation center C1 of the coupling shaft 14 and the rotation center C2 of the coupling shaft 18 of the coupling portion 17. The contact body 16 can be mounted to the arm 15 in such a manner that the center C3 coincides with the rotation center C1. In this case, the hole 16C may be referred to as a circular arc centered on the rotation center C1. The centers of rotation C1, C2 are also referred to as centerlines. The shape of the hole 16c is not limited to the above shape. For example, the hole 16c may be a linear long hole.
The contact body 16 is provided with two female screw portions 16 b. Specifically, the wall 20a is provided with two female screw portions 16 b. The hole 16c is located between the two internal thread portions 16 b.
As shown in fig. 4 and 5, the connection portion 17 connects the tip portion 15a of the arm 15 and the contact 16. The coupling portion 17 has a coupling shaft 18 and a fixing portion 19. The connecting shaft 18 is an example of the 2 nd connecting shaft.
As shown in fig. 4, the coupling shaft 18 is provided at the distal end portion 15a of the arm 15. The coupling shaft 18 is inserted into the hole 16c so as to be relatively movable with respect to the contact body 16 and relatively rotatable with respect to the contact body 16. Specifically, the coupling shaft 18 is inserted into the hole 16c so as to be movable relative to the contact 16 in a direction intersecting the axial direction of the coupling shaft 14. Specifically, the coupling shaft 18 is inserted into the hole 16c so as to be movable relative to the contact 16 in the longitudinal direction of the hole 16c (in the arc-like direction along the hole 16 c).
The fixing portion 19 fixes the position of the coupling shaft 18 with respect to the hole 16c so that the relative position between the hole 16c and the coupling shaft 18 can be adjusted. Specifically, the fixing portion 19 fixes the position of the coupling shaft 18 with respect to the hole 16c so that the relative position between the hole 16c and the coupling shaft 18 in the direction intersecting the axial direction of the coupling shaft 14 can be adjusted. Specifically, the fixing portion 19 fixes the position of the connection shaft 18 in the longitudinal direction of the hole 16c with respect to the hole 16c so that the relative position between the hole 16c and the connection shaft 18 in the longitudinal direction of the hole 16c can be adjusted.
As shown in fig. 4 and 5, the fixing portion 19 includes a plate-shaped base 31, a bearing 32, and two engaging members 33.
As shown in fig. 7, the base 31 is provided with a hole 31a for the bearing 32 and two holes 31b for the joint member 33. The hole 31a penetrates the base 31 in the thickness direction of the base 31, i.e., in the axial direction of the connecting shaft 14. The bearing 32 is fitted into the hole 31 a. The hole 31b penetrates the base 31 in the thickness direction of the base 31, i.e., in the axial direction of the connecting shaft 14. The hole 31b is formed in an arc shape (circular arc shape) along the hole 16 c. The hole 31a is located between the two holes 31 bc. The engaging member 33 is fitted into the hole 31 b.
The coupling member 33 shown in fig. 5 is a male screw member such as a bolt or a screw. The engaging member 33 is engaged with the female screw portion 16b of the contact 16 in a state of being fitted into the hole 31b of the base 31. Thereby, the base 31 and the contact 16 are fixed by the two coupling members 33 in a state where the base 31 overlaps the wall 20a of the contact 16. The coupling member 33 is relatively movable with respect to the base 31 along the longitudinal direction of the hole 31b (along the arc-like direction of the hole 16 c) in a state where it is not coupled to the female screw portion 16 b.
As shown in fig. 8, the bearing 32 includes a cylindrical portion 32a and a flange portion 32b protruding from an end portion of the cylindrical portion 32 a. The coupling shaft 18 is fitted into the cylindrical portion 32 a. The cylindrical portion 32a supports the coupling shaft 18 to be rotatable relative to the base 31. The bearing 32 is attached to the base 31 in a state where the cylindrical portion 32a is fitted into the hole 31a of the base 31 and the flange portion 32b overlaps the base 31. The bearing 32 is, for example, an oilless bearing. The bearing 32 may be another type of bearing.
In the emergency brake device 1 configured as described above, when the drive train 112 extends from the initial state, the contact 16 moves downward while pressing the drive train 112. Thereby, the arm 15 rotates in one direction (clockwise in fig. 2) about the coupling shaft 14. Thereby, the pawl member 12 rotates in one direction integral with the arm 15 to approach the ratchet 11. That is, the detection unit 13 detects the extension of the drive chain 112. Further, when the drive chain 112 is extended by a predetermined amount or more, that is, when the detector 13 detects the slack (abnormality) of the drive chain 112, the pawl member 12 is hooked on the ratchet 11 to stop the rotation of the ratchet 11. Thereby, the rotation of the large sprocket 116, and thus the circling movement of the steps 120, is prevented.
Here, the drive mechanism 100a may have a changed specification, for example. For example, the small sprocket 111 or the large sprocket 116 may be replaced with a sprocket having a different diameter. In this case, since the track of the drive chain 112 changes, it is necessary to adjust the posture and position of the contact body 16 with respect to the coupling shaft 14 so that the contact body 16 of the emergency brake device 1 properly contacts the drive chain 112. At this time, since the predetermined responsiveness of the emergency brake device 1 can be ensured by holding the position of the pawl member 12 with respect to the ratchet 11, it is necessary to adjust the posture and position of the contact body 16 while holding the position (standby position) of the pawl member 12.
In adjusting the posture and position of the contact body 16, first, the operator removes the coupling member 33 from the female screw portion 16 b. Next, the operator adjusts the posture and position of the contact body 16 with respect to the coupling shaft 14 so that the contact body 16 is appropriately brought into contact with the drive chain 112. At this time, the coupling shaft 18 can move relative to the hole 16 c. Further, the operator couples the coupling member 33 to the female screw portion 16 b. At this time, since the hole 31b is an arc-shaped long hole, the relative posture between the base 31 (the connecting shaft 18) and the contact 16 can be adjusted.
As described above, in the present embodiment, the emergency braking device 1 is provided in the escalator 100 (passenger conveyor), and the escalator 100 includes: a small sprocket 111 (1 st sprocket) rotated by power from a motor 105 (driving source); a large sprocket 116 (2 nd sprocket) provided separately from the small sprocket 111 and driving the steps 120; and a drive chain 112 wound around the small sprocket 111 (1 st sprocket) and the large sprocket 116. The emergency brake device 1 includes: a coupling shaft 14 (1 st coupling shaft) provided along the axial direction of the rotary shaft 118 of the large sprocket 116 and rotatable; a ratchet 11 fixed to the rotary shaft 118; a pawl member 12 fixed to the coupling shaft 14, and rotating integrally with the coupling shaft 14 from a state of being separated from the ratchet 11 to be hooked on the ratchet 11, thereby preventing rotation of the ratchet 11; an arm 15 extending from the coupling shaft 14 and rotating integrally with the coupling shaft 14; a contact 16 mounted on the drive chain 112; and a connecting portion 17 connecting the tip end portion 15a of the arm 15 and the contact 16. A hole 16c is provided in the contact 16. The coupling portion 17 has: a coupling shaft 18 (the 2 nd coupling shaft) provided at the distal end portion 15a and inserted into the hole 16c so as to be relatively movable with respect to the contact 16 and relatively rotatable with respect to the contact 16 in a direction (a longitudinal direction of the hole 16 c) intersecting with the axial direction of the coupling shaft 14; a fixing portion 19 that fixes the position of the coupling shaft 18 with respect to the hole 16c so that the relative position between the hole 16c and the coupling shaft 18 in the direction intersecting the axial direction of the coupling shaft 14 (the longitudinal direction of the hole 16 c) can be adjusted.
According to such a configuration, since it is not necessary to divide the arm 15 into a plurality of (e.g., two) parts (members), it is possible to adjust the posture and position of the contact body 16 while holding the position of the claw member 12 while suppressing complication of the arm 15. In the present embodiment, the thickness of the arm 15 (the thickness along the axial direction of the connecting shaft 14) does not need to be increased.
Here, in the emergency brake device 1, the detection accuracy of the detection unit 13 is improved. The detection accuracy of the detection unit 13 is easily improved as the torque around the coupling shaft 14 acting on the distal end portion 15a of the arm 15 is larger. In contrast, in the present embodiment, since the connection portion 17 (the fixing portion 19) as a structure for adjusting the posture and the position of the contact body 16 is provided at the distal end portion of the arm 15, the detection accuracy of the detection portion 13 can be improved as compared with a structure for adjusting the posture and the position of the sliding body provided at the intermediate portion of the arm.
In the present embodiment, the hole 16c has an arc shape protruding in a direction away from the coupling shaft 14.
With this configuration, the contact 16 and the coupling shaft 18 can be moved relative to each other along the longitudinal direction of the hole 16 c.
In the present embodiment, the coupling portion 17 has a bearing 32 that rotatably supports the coupling shaft 18.
With this configuration, wear of the coupling shaft 18 can be suppressed.
According to the above embodiment, a novel configuration is obtained in which the posture and position of the contact body 16 can be adjusted while holding the position of the claw member 12, while suppressing complication of the arm 15.
In the above-described embodiment, the escalator 100 is described as an example of a passenger conveyor in which a plurality of steps 120 connected in a loop form are operated so as to move in a circulating manner, but the present embodiment is not limited to the escalator 100, and can be applied to other types of passenger conveyors such as a moving walkway.
While the embodiments and modifications of the present invention have been described, the embodiments and modifications are merely presented as examples, and the scope of the present invention is not intended to be limited. The above embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. The above-described embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the invention described in the claims and equivalent ranges thereof.
