Below, about the 1st embodiment of the present utility model, describe with reference to accompanying drawing.
The illustrative passenger conveyors 1 of Fig. 1 is the escalator of safety device (hereinafter referred to as safety device) 30 of using the passenger conveyors of an embodiment of the present utility model.In addition, in the present embodiment, as the passenger conveyors of application safety device 30 and the situation of escalator is described, but also can be to moving sidewalk application safety device 30.
Passenger conveyors 1 by making a large amount of step 2 loopy moving between the gangway 9 of the gangway 8 of high-rise side and low layer side, is carried the passenger who takes at the pedal of step 2 across ground, the upper and lower as shown in Figure 1.
A large amount of steps 2 links by circular step chains 3, is disposed in the main frame 4 that is known as truss that arranges under the floor of building.
High-rise side in the inside of main frame 4 disposes sprocket wheel 5 and possesses the actuating device 6 of CD-ROM drive motor and reductor, and the low layer side in the inside of main frame 4 disposes sprocket wheel 7.
Set up step chains 3 between the sprocket wheel 7 of the sprocket wheel 5 of high-rise side and low layer side, along with actuating device 6 makes sprocket wheel 5 rotary actuations, step chains 3 is loopy moving between sprocket wheel 5 and sprocket wheel 7, step 2 also with step chains 3 loopy moving integratedly.
Be provided with the railing 10 of pair of right and left in the both sides of step 2, at the circumference of these railings 10 moving hand-rail 12 be installed.
As shown in Figure 2, railing 10 possess in the both sides of step 2 the upright railing panel 11 that arranges, at the fixing main cover plate 13 of the periphery of railing panel 11, be fixed on the upper surface 13a of main cover plate 13 and support the armrest cover plate 14 of moving hand-rail 12 and in the bib portion 15 of the bottom of railing panel 11 configuration.
The section shape of main cover plate 13 is at the コ of lower opening word shape, the pair of sidewalls of main cover plate 13 is spaced from each other predetermined distance extends along the moving direction X of step 2, is positioned at the upper end link of sidewall and railing panel 11 in the Width outside of passenger conveyors 1.
The section shape of armrest cover plate 14 is the up コ word shape of opening, and the pair of sidewalls of armrest cover plate 14 is spaced from each other predetermined distance along the moving direction X extension of step 2.Be provided with the guiding rail 16 that extends towards Width foreign side in the upper end of pair of sidewalls, support slidably the inner peripheral surface of moving hand-rail 12.
As shown in Figures 2 and 3, bib portion 15 possess with step 2 sides of railing 10 namely the inboard internal frame 17 that covers, with the outrigger 18 of the outer side covers of railing 10 and the skirt panel 19 of configuration relative to the side of step 2, internal frame 17 stops up between the bottom with skirt panel 19 and railing panel 11.
The skirt panel 19 of the passenger conveyors 1 of such structure is equipped with detection lug 32, switch 34, elastic body 36 and holding member 38, consists of safety device 30 with them.Safety device 30 arranges along the moving direction X of step 2, and clamping has footwear or foreign matter among the gap S between step 2 and skirt panel 19 if detect, and the running of passenger conveyors 1 is stopped.In addition, in the present embodiment, as shown in Figure 1, safety device 30 is along the moving direction X of step 2 from being set near the gangway 8 of high-rise side near the gangway 9 of low layer side.
Particularly, as shown in Figure 3, detection lug 32 possesses axial region 32a and compares the large abutting part 32b of above-below direction length in the front end setting of axial region 32a, with axial region 32a, be configured to the through hole 19a middle shaft part 32a that is arranged at skirt panel 19 axially X insert logically, abutting part 32b is outstanding from skirt panel 19 above step 2.
The stage portion 32c of the upper and lower end parts that is arranged at abutting part 32b of detection lug 32 is owing to the application force of elastic body 36 is pressed, holding member 38 when making abutting part 32b outstanding from holding member 38, and skirt panel 19 between keep detection lug 32.As shown in Figure 4, the length of the length direction of holding member 38 (being the moving direction X of step 2) arranges to such an extent that equate with the abutting part 32b of detection lug 32, and the Zone Full that spreads all over the length direction of holding member 38 arranges the abutting part 32b of detection lug 32.
In the safety device 30 of above such present embodiment, if clamping foreign matter and foreign matter are near skirt panel 19 in the gap between step 2 and skirt panel 19, then this foreign matter overcomes the application force of elastic body 36 and the abutting part 32b of detection lug 32 is pushed, and makes switch 34 actions and the running of passenger conveyors 1 is stopped.
In such safety device 30, owing to not using electric contact, therefore be difficult to cause that because of aging the contact is bad, and, for detection of the abutting part 32b of foreign matter from skirt panel 19 to step 2 top outstanding, therefore foreign matter directly is connected to abutting part 32b, can precision detects well that clamping has this situation of foreign matter in the gap between step and skirt panel.
In addition, in the safety device 30 of present embodiment, along the length of the holding member 38 of the moving direction X of step 2 arrange with the equal in length of the abutting part 32b of detection lug 32, the Zone Full that spreads all over the length direction of holding member 38 arranges the abutting part 32b of detection lug 32, therefore the abutting part 32b of in a big way configuration detection sheet 32 that spreads all over the moving direction X of step 2, can detect that clamping has foreign matter in the gap between step and skirt panel, can improve safety.
(the 2nd embodiment)
Then, about the 2nd embodiment of the present utility model, describe with reference to Fig. 4.In addition, the additional same-sign of the structure identical with the structure that illustrates is omitted repeat specification in the 1st embodiment.Difference between the 2nd embodiment and above-mentioned the 1st embodiment is to possess the loud speaker 42 of output warning tones as report section.
As shown in Figure 5, on internal frame 17, many loud speakers 42 separate step 2 moving direction X predetermined distance and configure.
And, if because foreign matter and the abutting part 32b of detection lug 32 is pushed into, then switch 34 action and detect the displacement of detection lug 32, be consecutively detected at switch 34 in the situation of time less than predetermined time T of displacement of abutting part 32b, from loud speaker 42 output warning tones, passenger's report is in dangerous this situation of state.In addition, also can be, detect in the part of a plurality of switches 34 in the situation of displacement of abutting part 32b of detection lug 32, the loud speaker 42 output warning tones that approach from the switch 34 with the displacement that detects abutting part 32b.
On the other hand, if switch 34 continues to detect the displacement of detection lug 32 more than predetermined time T, the running of passenger conveyors is stopped.
In the safety device 30 of above such present embodiment, if the displacement of detection lug 32 is the short time then to impel the passenger to note from loud speaker 42 output warning tones, when more than predetermined time T, continuing to detect the displacement of detection lug 32, passenger conveyors 1 is stopped, therefore can corresponding to the output of carrying out warning tones detection time of displacement and the stopping of passenger conveyors 1 of detection lug 32 interimly, not have the situation that passenger conveyors 1 unnecessarily stops.
Embodiment of the present utility model more than has been described, but these embodiments are to point out as an example, and are not intended to limit the scope of utility model.These embodiments can be implemented with other various forms, in the scope that does not break away from the utility model purport, can carry out various omissions, replacement and change.These embodiments and distortion thereof are included in the scope and purport of utility model, are also contained in equally in the utility model and equivalency range thereof of scope record of claim.
