Abstract
The invention discloses a pedal protection device on a moving sidewalk. The device comprises inductive switches which can be arranged below pedals close to the revolution parts of the moving sidewalk in the pedal rail-returning horizontal sections at the two ends of the moving sidewalk and are used for sending a signal of stopping the moving sidewalk in the case of pedal losses. The pedal protection device has the following advantages: the inductive switches detect whether the pedals on the moving sidewalk are continuous; and in the case of pedal losses, the inductive switches send a signal of stopping the moving sidewalk, so that the moving sidewalk stops, thereby avoiding the area without pedals from rotating again to an operation surface carrying passengers, guaranteeing personal safety of the passengers and improving the safety performance of the moving sidewalk.
Description
Technical field
The present invention relates to moving sidewalk upper footboard fender guard.
Background technology
On moving sidewalk, pedal is by fixed block and being bolted on the chain, and when bolt looseness, on the running face that carries the passenger, pedal is a difficult drop-off, but when having arrived upper and lower side round end place, footway, pedal drops easily.After pedal is lost, there is not the zone of pedal, when forwarding on the running face that carries the passenger again, will cause serious safety misadventure, cause passenger's injures and deaths.
Summary of the invention
The purpose of this invention is to provide the pedal reserve device that moving sidewalk can be out of service when inductive switch being set making pedal take place lose.
For achieving the above object; the technical solution used in the present invention is: moving sidewalk upper footboard fender guard, described pedal reserve device comprise that the pedal that can be arranged on described moving sidewalk two ends returns the rail horizontal segment and is being used for sending the inductive switch that makes described moving sidewalk signal out of service below the pedal at the revolution position of close this moving sidewalk when described pedal takes place to lose.
Preferably, described inductive switch have can according to and described pedal between vertical distance judge the probe whether this pedal is lost.
Preferably, described pedal returns and offers the oval hole of extending up and down on the guide rail fagging of rail, and the described inductive switch of cooperation by this oval hole and bolts and nuts can be arranged on the described guide rail fagging up or down.
Because the utilization of technique scheme, whether the present invention compared with prior art has following advantage: continuous by the pedal that inductive switch detects on the moving sidewalk, when the pedal loss occurring, inductive switch sends and stops terraced signal, moving sidewalk is out of service, when avoiding not having the zone of pedal to forward on the running face that carries the passenger again, guarantee passenger's personal safety, improve the safety performance of moving sidewalk.When pedal is lost, for the zone that guarantees not have pedal goes out before the broach again, moving sidewalk just can be out of service, because of considering the problem of stopping distance, the installation site of inductive switch can not be too near to the broach place, thus this inductive switch can be arranged on moving sidewalk up and down the pedal at two ends return the rail horizontal segment below near the pedal at the revolution position of this moving sidewalk.
Description of drawings
Accompanying drawing 1 is for being provided with vertical scheme drawing of inductive switch in the moving sidewalk lower end among the present invention;
Accompanying drawing 2 is for being provided with vertical scheme drawing of inductive switch in the moving sidewalk upper end among the present invention;
Accompanying drawing 3 is a cross sectional representation of the present invention.
The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1-3, moving sidewalk upper footboard fender guard comprises inductive switch 1, and this inductive switch 1 can be arranged on the below of the pedal 2 of return phase, and this inductive switch 1 is used for sending when pedal takes place to lose the signal that makes moving sidewalk out of service.When pedal is lost, for the zone that guarantees not have pedal goes out before the broach again, moving sidewalk just can be out of service, because of considering the problem of stopping distance, the installation site of inductive switch 1 can not be too near to the broach place, so this inductive switch 1 can be arranged on moving sidewalk up and down the pedal at two ends return the rail horizontal segment below near the pedal 2 at the revolution position of this moving sidewalk, as illustrated in fig. 1 and 2.Whether continuous by the pedal that inductive switch 1 detects on the moving sidewalk, when the pedal loss occurring, inductive switch 1 sends and stops terraced signal, moving sidewalk is out of service, when avoiding not having the zone of pedal to forward on the running face that carries the passenger again, guarantee passenger's personal safety, improve the safety performance of moving sidewalk.
This inductive switch 1 has detection probe, determine as distance of reaction L whether this pedal is lost by the vertical distance between probe and the detected pedal tread, under normal circumstances, the signal that probe on the inductive switch 1 sends is accepted by probe after the pedal reflection again, probe detects suitable distance of reaction, and then pedal normally moves, in case pedal is lost, then probe detects less than distance of reaction, makes moving sidewalk stop so inductive switch 1 sends signal.
Claims (3)
1. moving sidewalk upper footboard fender guard is characterized in that: described pedal reserve device comprises that the pedal that can be arranged on described moving sidewalk two ends returns the rail horizontal segment and be used for sending the inductive switch that makes described moving sidewalk signal out of service when described pedal takes place to lose below the pedal near the revolution position of this moving sidewalk.
2. pedal reserve device according to claim 1 is characterized in that: described inductive switch have can according to and described pedal between vertical distance judge the probe whether this pedal is lost.
3. pedal reserve device according to claim 1; it is characterized in that: described pedal returns and offers the oval hole of extending up and down on the guide rail fagging of rail, and the described inductive switch of cooperation by this oval hole and bolts and nuts can be arranged on the described guide rail fagging up or down.
