When the movable frame 83 rises and reaches the second outer end and the second detector 13 is activated, the rotation of the lifting motor 82 is stopped and the drive band 84c engages with the human power body 42.72. Also, as the movable frame 83 rises, the rods 6d and 73d
are pressed and raised, the levers 6a, 73a rotate, and the pins 6b, 73b are removed from the pin holes 42a, 72a of the input body 42, 72, respectively. Then, the electric motor 85 is started and #(gears 84.a, 8
The drive band 84c runs through the input body 4b, and the input body 42
rotates, and due to the meshing of the bevel gears 43 and 44a, the spur gear 45° binion 45a, and the rack 5a, the 7-hole 5 becomes f! It protrudes from below the S2 type step and engages with the engaging piece 32k of the third type step 32, and the operation of the f:tS3 detector 14 cuts off the power supply to the electric motor 85 and stops it. At the same time, the rotation of the input body 42 is transmitted to the pinion 46 by the shaft 41, which drives the rack 47 that engages with the pinion 46 to push down the cam 48 which operates the second stop command switch S7. At this time, the position of the cam 48 is such that the fork 5 is in the engagement piece 32k.
When the engagement is completed, the switch S7 is at the position where it can be operated, and the electric motor 85 is stopped. Also,
The operation of detector 14 closes the (+)-detector 14-detector 14'-relay C7-(-) circuit, energizes memory relay C7, and self-holds through its normally open contact C7c. do. Further, the input body 72 rotates due to the movement of the drive band 84c, and the pinion 74. The engagement rod 76 comes out of the hole 32g and the engagement tag 32j via the rack 76a, and the riser 32i
The engagement of the vertical wall 32e is released, resulting in the state shown in FIGS. 9 and 10. Note that since the upper side of the driving gJ belt 84c is supported by the elastically supported support 84d,
The drive band 84c is smoothly engaged with the input body 42.72. Then, from the state shown in FIGS. 9 and 10, the electric lift () or 82 is started in the reverse direction, the movable frame 83 is lowered, and when the first detector 12 is pressed, the electric rock 82 is stopped. . In addition, as the movable frame 83 is lowered, the blocking mechanisms 6 and 73 cause the surface rearward movement beam structure 4. The operation of the locking mechanism 7 is blocked. On the other hand, due to the energization of memory relay C7, its normally open contact C7
a, C7b is closed, the closed contact C7a is opened, and the normally closed contact C7d is opened, thereby disabling the operation of the normal operation start switch S3. In addition, the second car stopped at the lower end of the outgoing route 2a. 33rd step 3

And the second. 33rd step 31. , 32 is loaded with a wheelchair, the escalator is operated in the upward direction, and as the 23rd step 31 moves to the inclined section, the movable tread 32) supported by the 7t-rail 5 becomes the third type. Step 3? As shown in FIG. 11, the loading space for chairs is held horizontally.
When the actuating piece 32m reaches a predetermined position in front of the upper end, the actuating piece 32m faces the proximity switch S5'.
is turned on to deenergize stop command relay C5. When relay C5 is deenergized and its contacts C5a and C5b are opened, contactors C2 and C3 are deenergized, so motor 1k
and first brake 1g, f52 brake coil 11
The power supply to the escalator will be cut off and the escalator will stop. During this time, the step moves slightly in the running direction due to inertia, which causes the motor 448 to operate the switch S7', turn off the switch S7r, and connect the circuit of the contactor C2.
The circuit is opened in addition to the opening caused by i C5a. Therefore, due to the non-operation of the switch 85', the contact IC5a
Even if it does not open, it can be stopped without going too far. Due to the deenergization of contactor C2, its normally open contacts C2c,
When C2f opens, call relay C1 is de-energized, and by opening its contact C1a, eleven-way operation relay C6 is de-energized. Also, by opening the contacts C1d and C6e, (+) - contact C1d - contact C6e
-The circuit of relay C3-(-) is closed and the stop command IJ
l/-C5 is energized and ready for the next run. 6-1 After a certain period of time, contacts C4a and C4b of timer C4 close. After the escalator comes to a complete stop, the wheelchair is removed. Next, the drive member 8' provided at the upper end of the outgoing path 2a is raised to engage the drive band 84C' with the input body 42.72,
The electric motor 85' retires the fork 5 to release support from the f53 type pedal 3S2, and then pulls up the switch 48 and turns on the switch S6. Avoid contact with S6'. Further, when the 7 oak 5 retires, the upper detector 14' is turned off and the memory relay C7 is deenergized. Further, the engagement rod 76 is connected to the engagement hole 32. The movable step plate 3211 is held by the 33rd step 32 by being fitted into the i+ hole 32°. Deenergization of relay C7 causes its normally open contact C7a. C71+ and C7c open, and normally closed contact C7d closes, disabling the circuit for wheelchair operation. After that, drive l

Of these, even if one brake force weakens or disappears, the other brake will operate normally, so the stopping distance will be a little longer, but the second. The 33rd step can be sufficiently stopped within a predetermined position of the entrance and exit, so that the 2nd and 33rd steps do not run into the reversing part while being engaged.

【Effect of the invention】

According to the invention described above, by doubling the means for issuing a stop command using means with different characteristics and by using a dual system of brakes, even if one of the stop commands fails, it will almost always be normal. It is possible to realize a highly reliable escalator device without overshooting the stop position and without causing a serious accident even if one brake fails.
