Description
Technical field
The utility model relates to a kind of elevator weighting apparatus.
Background technology
In prior art, conventional elevator weighting apparatus generally adopts micro-switch to detect super full signal, not only complex structure, and the size that can not export the load carrying ability in car in real time.
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 and a kind ofly the load carrying ability of car can be converted to the elevator weighting apparatus that voltage signal exports elevator master control system in real time to.
For achieving the above object, the utility model by the following technical solutions:
A kind of elevator weighting apparatus, is characterized in that, comprising:
Hall magnetic sensor, it is fixedly mounted on the below at the bottom of sedan-chair;
Control amplification circuits, it is connected with described Hall magnetic sensor;
Induced magnet, it to be fixed at the bottom of described sedan-chair and to be oppositely arranged with described Hall magnetic sensor, described induced magnet;
Extraction cable, it connects described control amplification circuits and elevator master control system, and the voltage signal that described control amplification circuits exports is delivered to described elevator master control system by described extraction cable in real time.
Preferably, also comprise installation fixed housing, described Hall magnetic sensor and described control amplification circuits are arranged in described installation fixed housing.
Further, also comprise connection bracket, described connection bracket is fixedly mounted on and is positioned under sedan-chair square under described sedan-chair on frame, and described installation fixed housing is fixed in described connection bracket.
Wherein, described installation fixed housing is the tube-like envelope with hollow reservoir, and described Hall magnetic sensor and described control amplification circuits are arranged in described hollow reservoir.
Principle of work of the present utility model: according at the bottom of sedan-chair along with load carrying ability size does the principle that elasticity moves up and down, detect the change in displacement of following and doing the induced magnet moved up and down at the bottom of sedan-chair by the Hall magnetic sensor being fixed under sedan-chair side, thus realize the real-time detection of load carrying ability in lift car and by controlling amplifying circuit, voltage signal flowed to elevator master control system in real time.
Voltage signal scope that amplifying circuit exports in real time is controlled at 0 ~ 10V in the utility model.
The technical solution of the utility model abandons the device that conventional micro-switch etc. only detects super full signal, but detect induced magnet at the bottom of sedan-chair with the change in displacement done elasticity at the bottom of sedan-chair and move up and down by the Hall magnetic sensor being arranged under sedan-chair side, the voltage signal of load carrying ability in real-time output-response car, followability is good.And the utility model has compact, compact conformation, safe and reliable, installation, advantage easy to maintenance.
Accompanying drawing explanation
Fig. 1 is front view of the present 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.
Embodiment one
Refer to Fig. 1, a kind of elevator weighting apparatus, comprise Hall magnetic sensor 1, control amplification circuits 2, fixed housing 3, connection bracket 4, induced magnet 5 and extraction cable 6 are installed.
Wherein, install fixed housing 3 for having the tube-like envelope of hollow reservoir, Hall magnetic sensor 1 and described control amplification circuits 2 are arranged in described hollow reservoir.Connection bracket 4 is for being bent into step-like support, and its lower end to be bolted under sedan-chair on frame 7.Install fixed housing 3 and have outside thread, connection bracket 4 is provided with perforation, and the axial direction installing fixed housing 3 is vertically fixed in connection bracket 4 by each nut up and down afterwards through this perforation.Hall magnetic sensor 1 is arranged on the upper end of installing fixed housing 3, controls amplification circuits 2 and is arranged in hollow reservoir.Induced magnet 5 to be fixed at the bottom of sedan-chair on 8 and to be oppositely arranged with Hall magnetic sensor 1.
Between induced magnet 5 and Hall magnetic sensor 1, there is gap, when car contains changes in weight, induced magnet 5 is along with 8 doing elasticity and move up and down at the bottom of sedan-chair, thus Hall magnetic sensor 1 can detect changes of magnetic field and be converted to the change of voltage signal by controlling amplifying circuit 2 in real time.Wherein, induced magnet 5 adopts strong magnetic magnet, such as magnetic links.
Extraction cable 6 is connected with control amplification circuits 2 and draws from the lower end of installing fixed housing and be connected to elevator master control system.Extraction cable 6 is by voltage signal real-time Transmission to elevator master control system, and elevator master control system can obtain the size of the load carrying ability in lift car in real time by this real-time voltage signal.In the present embodiment, this voltage signal scope is 0 ~ 10V.
The elevator weighting apparatus compact of the present embodiment, compact conformation, wiring is succinct, installs, debugging, easy to maintenance, and integration degree is high.
The load carrying ability continually varying real-time voltage signal reacting lift car can be obtained by the elevator weighing apparatus of the present embodiment, more be conducive to elevator to intellectuality, digitalisation, web development, convenient and swift, safe and reliable, can the performance of hoisting elevator product and class.
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.
