Abstract
The utility model discloses a kind of pedal break detector apparatus of escalator, described escalator comprises truss, runs along the length direction of truss the pedal arranged, described pedal break detector apparatus comprises measure loop, measure loop comprises power supply, the cable be in series and the relay with normally open contact, described normally open contact is serially connected in the safety return circuit of escalator, and described cable extends along the length direction of truss the below being arranged in the whole service stroke of pedal.The utility model is by the relay that is serially connected in escalator safety return circuit and be arranged in the cable below the whole stroke of pedal along the length direction of truss, cable is broken when pedal ruptures, make relay power-off, thus safety return circuit is disconnected, and then escalator is braked, achieve and the overall process of pedal fracture is detected.The utility model can realize carrying out overall process detection to the pedal crack conditions of escalator effectively, has structure simple, the advantage that cost of manufacture is lower.
Description
Technical field
The utility model relates to a kind of pedal break detector apparatus of escalator.
Background technology
According to GB escalator and moving sidewalk manufacture with safety standard " GB16899-2011 " relevant regulations is installed, the step of escalator or moving sidewalk (hereinafter referred to as escalator), pedal can detect in time when fracture occurring or losing pinpoints the problems and by the reliable stop of control system of escalator self, prevents personnel from colliding or extrude the injures and deaths caused.And in prior art, opto-electronic pickup is generally adopted to catch step or the pedal of disappearance, opto-electronic pickup is arranged on two fixed positions up and down of escalator, when step occurs that disappearance opto-electronic pickup sends breakdown signal to control mechanism, makes equipment realize braking.If pedal running the midway location fracture of stroke or sinking, then cannot detect in time, can not stop ladder in time, there is certain potential safety hazard.
Summary of the invention
In view of this, in order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of pedal break detector apparatus that can run the escalator of overall process detection pedal fracture and time control stop ladder at pedal.
For achieving the above object, the utility model by the following technical solutions:
A kind of pedal break detector apparatus of escalator, described escalator comprises truss, runs along the length direction of truss the pedal arranged, it is characterized in that: described pedal break detector apparatus comprises measure loop, described measure loop comprises power supply, the cable be in series and the relay with normally open contact, described normally open contact is serially connected in the safety return circuit of escalator, and described cable extends along the length direction of described truss the below being arranged in the whole service stroke of described pedal.
Preferably, described cable is fixed on the crossbeam of described truss by multiple attachment point.
The quantity of described cable is many, and many described cables are arranged in juxtaposition along the Width of described truss, and many described cables are cascaded successively.In one embodiment, the quantity of cable is 4, and 4 cables are connected successively.
Principle of work of the present utility model is: when the pedal of escalator normally works, when not rupturing, and after energising, relay obtains electric, normally open contact adhesive, and staircase can work; If pedal ruptures suddenly in escalator operation process, when sagging, encounter cable, cable breakage, then relay current supply circuit disconnects, relay electric-loss, and now safety return circuit disconnects, and escalator quits work, thus ensures safety.
Compared to prior art, the utility model structure is simple, and in existing escalator system, increase only the overall process detection that 1 relay and corresponding cable just can realize rupturing to pedal, improvement cost is low, is suitable for applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the circuit diagram that the utility model is applied in the safety return circuit of escalator.
Fig. 3 is the circuit diagram of the measure loop in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Refer to Fig. 1 to Fig. 3, a kind of pedal break detector apparatus of escalator, be arranged in escalator, this escalator comprises truss 100, runs along the length direction of truss 100 the pedal (not shown) arranged, described pedal break detector apparatus comprises measure loop 200, described measure loop 200 comprises power supply 2, the cable 30 be in series and the relay 40 with normally open contact of powering to relay 40, described normally open contact is serially connected in the safety return circuit 300 of escalator, and safety return circuit is powered by power supply 1.
As shown in Figure 1, cable 30 extends along the length direction of truss 100 below being arranged in the whole service stroke of described pedal.The cable of suitable mechanical strength selected by cable 30, is fixed on the crossbeam 101 of truss 100 by multiple attachment point 31, can be pressed down when being subject to the power that pedal fracture is sunk.Cable 30 is 4, and 4 cables 30 are arranged in juxtaposition along the Width of truss 100, and 4 cables 30 are cascaded successively.In the present embodiment, the quantity of cable 30 is 4, and 4 cables 30 are connected in control housing by connection lead 50 after connecting successively again, and relay 40 is also arranged in control housing.Every root cable 30 is fixed by attachment point 31 in upper and lower end parts position, also can arrange attachment point 31 be fixed at the middle part of himself length direction.
As shown in Figure 2, except the relay-KTJ of measure loop of the present utility model, the safety return circuit of escalator is also in series with fire alarm interface (normally closed signal)-Fire, safety relay-KS01, safety relay-KS02, hand turning switch-S50, hand turning switch-S51, driving chain detector switch-KS07, driving chain detector switch-KS08, additional brake detecting device-SY3 and top scram button-SB11 successively.
After energising, relay 40 obtains electric, normally open contact adhesive, and escalator can normally run; If some pedals rupture suddenly in stroke in escalator operation process, encounter cable 30 when sagging, cable 30 ruptures, then relay 40 current supply circuit disconnects, relay 40 dead electricity, and now safety return circuit 300 disconnects, escalator quits work, thus ensures safety.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
