The elevator safety loop checking system
The utility model relates to a kind of elevator, particularly relates to a kind of elevator safety loop checking system.
Utilization very extensively we can say with daily life inseparable during elevator was built in modern times.In the running process of elevator, need to guarantee the general safety performance, so just require whether normal operation of each parts of elevator OBD detection in real time.Yet present elevator device usually only can be at the part safety return circuit, such as Room door; Gate detects, and the point-to-point completely detection that existing checking system does not carry out elevator device on the market so just can not well guarantee the safe operation of elevator various piece; And when detecting elevator faults, accurately the failure judgement point needs service personnel to go in person to detect; Waste time and energy, maintenance difficulties is high.It is thus clear that be necessary to make improvement.
The utility model content
The technical matters that the utility model will solve provides more comprehensive, the accurate elevator safety loop checking system of a kind of detection.
The utility model solves the technical scheme that its technical matters adopted:
The elevator safety loop checking system comprises the safety return circuit detecting unit, and this safety return circuit detecting unit has four test sides at least and is connected to elevator master control board, car top inspection station, pit maintenance box and layer door detector respectively, wherein:
Said master control board connects velocity limiter, jiggering equipment and wire holder through detection module at least respectively;
Said car top inspection station is at least respectively through detection module attachment security pincers, security window, sedan-chair top emergency stop switch and car door lock-switch;
Said pit maintenance box connects tightening device, upper and lower limit switch and counterweight buffer through detection module at least respectively;
Said layer door detector is through detecting device articulamentum every lock-switch.
Said detection module is the light-coupled isolation testing circuit.
The beneficial effect of the utility model: the safety return circuit detecting unit of the utility model; Detect three places at least respectively; Be elevator master control board, car top inspection station and pit maintenance box, elevator master control board, car top inspection station and pit maintenance box detect parts separately through detection module respectively simultaneously, form a comprehensive checking system of unification; Because its detection is comparatively detailed; Therefore when work, can judge accurately that which parts breaks down, and can send to apparatus for controlling elevator in real time, send to servicing center to dependent failure information accurately by ethernet monitored control system or GSM telecommunication system again; Let the related personnel in time know, therefore can make things convenient for follow-up attended operation greatly.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done simple declaration in will describing embodiment below.Obviously, described accompanying drawing is a part of embodiment of the utility model, rather than whole embodiment, those skilled in the art under the prerequisite of not paying creative work, other design plans and the accompanying drawing that can also obtain according to these accompanying drawings:
Fig. 1 is the system principle block scheme of the utility model.
The specific embodiment
Below will combine embodiment and accompanying drawing that the technique effect of design, concrete structure and the generation of the utility model is carried out clear, intactly description, with purpose, characteristic and the effect of understanding the utility model fully.Obviously; Described embodiment is a part of embodiment of the utility model, rather than whole embodiment, based on the embodiment of the utility model; Other embodiment that those skilled in the art is obtained under the prerequisite of not paying creative work all belong to the scope that the utility model is protected.
With reference to Fig. 1; The elevator safety loop checking system of the utility model; Comprise the safety return circuit detecting unit of always controlling 1; This safety return circuit detecting unit 1 has four test sides at least and is connected to elevator master control board 2, car top inspection station 3, pit maintenance box 4 and layer door detector 5 respectively, and wherein, master control board 2 respectively connects velocity limiter 21, jiggering equipment 22 and Crimping Pliers 23 through a detection module at least respectively; Car top inspection station 3 is at least respectively respectively through detection module attachment security pincers 31, security window 32, sedan-chair top emergency stop switch 33 and car door lock-switch 34; Pit maintenance box 4 respectively connects tightening device 41, upper and lower limit switch 42 and water bumper 44 through a detection module at least respectively; Layer door detector 5 is through detecting device articulamentum every lock-switch 51.Certain difference according to actual needs can also be expanded, to correspond to each parts that need detect of elevator through detection module.Wherein detection module is used to detect each detailed parts and detects, and can adopt the light-coupled isolation testing circuit to realize usually, and each detection module correspondence is arranged in master control board 2, car top inspection station 3, pit maintenance box 4 and the layer door detector 5.
Certainly; The invention is not limited to above-mentioned embodiment; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
