Abstract
The utility model discloses an elevator weighing device, comprising an elevator car, an elevator control system and a sensor (1), wherein the elevator control system is connected with the sensor (1); an internal platform (2) of the elevator car is provided with a first switch frame (3); an external platform (4) of the elevator car is provided with a second switch frame (5); the sensor (1) is arranged on the second switch frame (5); and magnetic steel (6) is arranged on the first switch frame (3) and is vertically installed relative to the sensor (1). The device has ingenious conception, simple structure and high stability and reliability and is convenient to install and debug.
Description
Technical field
The utility model relates to a kind of elevator weighing apparatus.
Background technology
Elevator not only needs to ask it to move safely and efficiently as the vertical transportation transportation means in the building, and the comfort of elevator is also had higher requirement.The operation of elevator is to rely on the rotation of motor to realize the output torque the when weight of lift car directly has influence on electric motor starting.Along with passenger quantity what with car in body weight different of passenger, the total weight of car also changes, at this moment we expect the difference of motor according to car weight, export different moments.
The LOAD CELLS of using on traditional elevator all is the LOAD CELLS of inductance type, cause the variation of inductance component inductance value by the change in location of iron core and inductance component, by amplifying circuit the variation of inductance value is converted to voltage or current signal then, by the measurement to voltage or current signal, the perception lift car is unloaded, fully loaded or overload condition.This traditional inductance type LOAD CELLS output voltage linearity degree is not fine, and output voltage is influenced by temperature, power-supply fluctuation or external interference easily, thereby the stability and the reliability of this traditional inductance type LOAD CELLS are all very poor.
Control the method for car load-carrying at present, be to adopt to place the LOAD CELLS of car bottom to carry out the load-carrying data sampling, sampled signal is directly inputted to the analog input end of machine room control housing by trailing cable, the machine room control housing is according to the sampled analog signal that receives, export corresponding execution command, the operation of control elevator.But, because what transmit on trailing cable is the analog sampling signal of LOAD CELLS output, this signal transmits the decay that has in various degree on cable, particularly when the car stroke strengthens, the trailing cable that connects LOAD CELLS and machine room control housing also increases simultaneously, and the degree of sampled analog signal attenuation can increase, and the signal that might cause being input to the machine room control housing is inaccurate, thereby make machine room control housing output error instruction, make the elevator maloperation.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of elevator weighing apparatus.This device is skillfully constructed, simple in structure, Installation and Debugging are convenient, stability and reliability height.
For achieving the above object, the utility model solves the technical scheme that its technical matters adopts and is:
A kind of elevator weighing apparatus, comprise lift car, apparatus for controlling elevator and sensor, described apparatus for controlling elevator is connected with sensor, the interior chassis of described lift car is provided with first switch frame, the outer chassis of lift car is provided with the second switch frame, described sensor is arranged on the second switch frame, and described first switch frame is provided with magnet steel, and this magnet steel is vertically installed with respect to sensor.
As optimal way, described sensor is a Hall switch sensor.
As optimal way, be provided with cushion blocking between described interior chassis and the outer chassis.
When an alive metal or wafer vertically were placed in the magnetic field, the two ends of thin slice will produce difference of potential, and this phenomenon just is called Hall effect.Hall element is a kind of magnetic field sensor of making according to Hall effect.Hall switch sensor is by voltage stabilizer, Hall element, differential amplifier, and this schmitt trigger and output stage are formed, and it exports digital quantity.The utility model combines a permanent-magnet steel and Hall switch sensor and records the positive distance with the permanent-magnet steel front of sensor, thereby has obtained the load carrying ability of car.Because Hall switch sensor output digital signal has overcome the shortcoming that analog signal decays, and has improved the stability and the reliability height of elevator.Further improve, be provided with cushion blocking between interior chassis and the outer chassis, increased the traveling comfort of elevator.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model device is skillfully constructed, simple in structure, Installation and Debugging are convenient, stability and reliability height.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment: as shown in Figure 1, a kind of elevator weighing apparatus, comprise lift car, apparatus for controlling elevator and sensor 1, described apparatus for controlling elevator is connected with sensor 1, the interior chassis 2 of described lift car is provided with first switch frame 3, and the outer chassis 4 of lift car is provided with second switch frame 5, and described sensor 1 is arranged on the second switch frame 5, described first switch frame 3 is provided with magnet steel 6, and this magnet steel 6 is vertically installed with respect to sensor 1.Described sensor 1 is a Hall switch sensor.Be provided with cushion blocking 7 between chassis 2 and the outer chassis 4 in described.
The adjustment of distance between magnet steel and the sensor: when the elevator volume carries, magnet steel is placed the dead ahead of sensor, the front of significant surface alignment sensor, the position of adjusting sensor is just exported it, and lock sensor screw, volume carry to adjust and finish.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
