Abstract
To provide a passenger conveyor capable of suppressing to the minimum the degree of damage caused by the collision of comb teeth at a tip of a boarding floor with a tread by rapidly detecting the lift of a front wheel of footsteps.
Description
Technical field
The present invention relates to be used for device of passenger conveyor such as the escalator of conveying people and electronic passage, relate in particular to and a kind ofly can detect the unusual device of passenger conveyor abnormal detector of pedal.
Background technology
Before this, the various method of inspections that step floats or sinks that are used to detect have been disclosed.A kind of unusual method of step that is used to detect is especially disclosed in patent documentation 1, its by detect step from the sloping portion that carries out the staged motion towards the detection that is wholely set with entire curve part and horizontal component with the top of track or moving of below, detect the unusual of step.
Patent documentation 1: the patent of invention spy of Japan opens 2003-104679 communique (the 7th page, Fig. 3)
, in above-mentioned patent documentation 1 disclosed scheme, according to detecting floating of trailing wheel with the variation of track along the detection of step trailing wheel guide rail setting.Therefore, when the situation that occurs having only front-wheel to float a little, this method can not detect unusually.So, in the time of when step arrives the gangway under the state that front-wheel floats near, the situation that the broach of the pedal of passenger's standing surface and gangway front end collides then might appear constituting, may cause pedal to separate when the most serious with step, like this, when repairing, just require a great deal of time and expense.
Summary of the invention
For this reason, the object of the present invention is to provide a kind of device of passenger conveyor, this device of passenger conveyor can in time detect the situation of floating of step front-wheel, thereby will be collided and the degree of injury that produces is controlled in the minimum zone by the broach of gangway front end and pedal.
To achieve these goals, the invention provides a kind of device of passenger conveyor, this device of passenger conveyor is provided with ring-type and connects with the mobile a plurality of steps that circulate with the both sides of the vertical moving direction that is built up in described step and along the railing of periphery guiding with the synchronization-moving moving hand-rail of described step in crossing over the main frame that lower floor's floor and upper strata floor be provided with; Push at least a portion that the front-wheel of described step front-wheel pushes rail from the top with movable form setting, when the amount of movement of pushing rail when described movable front-wheel reaches specified amount, switch motion, thus device of passenger conveyor is stopped.
(invention effect)
According to the present invention, can realize a kind of device of passenger conveyor, this device of passenger conveyor can in time detect the situation of floating of step front-wheel, thereby will be collided and the degree of injury that produces is controlled in the minimum zone by the broach of gangway front end and pedal.

The specific embodiment
Followingly embodiments of the invention are described according to Fig. 1～Fig. 5.
As shown in Figure 1, in escalator, in the main frame 2 of crossing over lower floor's floor (not shown) and 1 setting of upper strata floor, be provided with: be connected with the mobile a plurality of steps 4 that circulate with the step chain 3 of ring-type as a kind of device of passenger conveyor, vertically be built up in the both sides of step 4 moving directions and the railing 6 of edge periphery guiding and described step 4 synchronization-moving moving hand-rails 5, reel in two ends of the length direction of main frame 2 described step chain 3 and be supported on the rope sheave 7 of 1 below, floor, gangway (upper strata floor) in the upper level part 8 of described main frame 2 with axle, be arranged in the upper level part 8 of described main frame 2 and by the motor 11 that rotates according to the control command of control setup 10 and retarder 12 constitutes and rotate the actuating device 13 of the described rope sheave 7 of driving via chain drive-belt 9.At this, the trailing wheel 14 of described step 4 is guided by the trailing wheel guide rail 15 that is laid in the main frame 2, and the front-wheel 16 of described step 4 is guided by front-wheel guide rail 17.In addition, this step 4 also has the pedal of standing for the passenger, and it meshes non-contactly with the broach 18 that is arranged on floor, gangway 1 front end of main frame 2 length direction ends and advances, and the downside on floor, gangway 1 moves in the opposite direction.
In addition, be provided with front-wheel and push rail above front-wheel 16, it is movable that this front-wheel is pushed rail at least a portion.Specifically, at sloping portion fixing front-wheel is set respectively and pushes rail 19, near floor, gangway 1, be provided with movable front-wheel and push rail 20, and pin the front-wheel 16 of step 4 from the top.
Following structure of movable front-wheel being pushed rail 20 with reference to Fig. 2 to Fig. 4 describes.As shown in Figure 2, push at this movable front-wheel switch 21 is installed in the rail 20, when the amount of movement of pushing rail 20 when movable front-wheel reaches specified amount, switch 21 actions, thus escalator is stopped.
Fig. 3 is the section-drawing of Fig. 2 A-A line, and movable front-wheel is pushed the state of rail 20 during the expression normal operation.Movable front-wheel is pushed rail 20, is supported on the support 23 across spring 22 elastic bodys such as grade, and when the upwards propelling thrust from front-wheel 16 acted on movable front-wheel and pushes rail 20, this movable front-wheel was pushed rail 20 and can be subjected to from elastomeric bounce.That is, movable front-wheel is pushed rail 20 be arranged on the escalator base side, up boosted by elastic force easily avoiding.In addition, when the passenger on the step 4 moved, for example, when inferior, the amount of movement that the degree of shaking that is produced on front-wheel 16 can not cause movable front-wheel to push rail 20 reached specified amount on the passenger, and switch 21 can not move yet.Therefore, the situation that escalator frequently stops can not to appear.
On the other hand, when accompanying foreign material between the adjacent step 4 and under this state, arrive the broach 18 of floor, gangway 1 front end, the step 4 of back is up lifted, and simultaneously the front-wheel 16 of the step 4 of back is up lifted, and movable front-wheel is pushed rail 20 and moved towards the top.Fig. 4 is illustrated in the state that movable front-wheel when above-mentioned abnormal condition take place is pushed rail 20.And when the amount of movement of pushing rail 20 when movable front-wheel reached specified amount, switch 21 actions also shut down escalator.Thus, even accompany foreign material between the end of floor, gangway 1 side of pedal and the broach 18, also can in time stop the running of escalator by detecting the rising a little of the front-wheel 16 that produces in the rising of inlet floor 1 side with pedal.Therefore, can avoid the side end on the floor, gangway 1 of pedal to go out the top on floor, gangway 1, and the mechanical damage that causes that pedal separates with the body of step 4 etc.
In addition, in the present embodiment, a kind of as device of passenger conveyor is illustrated escalator, but concerning movable sidewalk, also can adopts identical structure.And, unusual in order to detect accurately, also a plurality of switches 21 and elastic body etc. can be set in the working direction of step 4.
