Description
Technical field
The present invention relates to a kind of elevator weighing apparatus.
Background technique
Elevator not only needs that it is asked safely and efficiently to run, and right as the vertical transportation means of transport in building
The comfort of elevator also has higher requirement.The operation of elevator is the rotation by motor to realize, the weight of lift car
Directly influence output torque when electric motor starting.With the weight of passenger in the number and carriage of passenger quantity
Difference, the total weight of carriage is also variation, at this moment it is desirable that motor exports different torques according to the difference of car weight.
Weighing sensor on traditional elevator is all the weighing sensor of inductance type, passes through iron core and inductance component
Change in location causes the variation of inductance component inductance, then by amplifying circuit the variation of inductance be converted to voltage or
Current signal, by the measurement to voltage or current signal, perceiving lift car is unloaded, fully loaded or overload condition.This biography
It is that very well, output voltage is easy by temperature, power-supply fluctuation or outer that the Inductance weighing cell output voltage of system, which is linearly spent not,
Boundary's interference effect, thus the stability of this traditional Inductance weighing cell and reliability are all very poor.
The method of control car weight at present is to carry out load-carrying data using the weighing sensor for being placed in cage bottom to adopt
Sample, sampled signal are directly inputted to the analog input end of computer room control cabinet by trailing cable, and computer room control cabinet is according to receiving
Sampled analogue signals, output phase should execute instruction, and control the operation of elevator.But since what is transmitted on trailing cable is
The analog sampling signal of weighing sensor output, the signal transmit on cable and have different degrees of decaying, especially work as sedan-chair
When compartment stroke increases, the trailing cable for connecting weighing sensor and computer room control cabinet also increases simultaneously, sampled analogue signals decaying
Degree will increase, it is possible to the signal inaccuracy for leading to be input to computer room control cabinet, to make computer room control cabinet output error
Instruction, makes elevator maloperation.
Summary of the invention
Goal of the invention of the invention is: in view of the above problems, providing a kind of elevator weighing apparatus.The device structure
Think that ingenious, structure is simple, installation and debugging are convenient, stability and high reliablity.
To achieve the above object, the technical solution adopted by the present invention to solve the technical problems is: a kind of elevator weighing dress
It sets, including lift car, elevator control system and sensor, the elevator control system is connected with sensor, the elevator car
It is provided with first switch frame on the interior chassis in compartment, second switch frame is provided on the outer chassis of lift car, the sensor is set
It sets on second switch frame, is provided with magnet steel on the first switch frame, which installs relative to sensor vertical.
The sensor is Hall switch sensor.
Resilient cushion is provided between the interior chassis and outer chassis.
When the metal or wafer to alive when one piece is placed vertically in magnetic field, the both ends of thin slice will be generated
Potential difference, this phenomenon are known as Hall effect.Hall sensor is a kind of magnetic field sensor made according to Hall effect.It opens
Pass type Hall sensor is made of voltage-stablizer, Hall element, difference amplifier, Schmitt trigger and output stage, it exports number
Word amount.The present invention, which combines a permanent-magnet steel and a Hall switch sensor, measures sensor front and permanent-magnet steel
Positive distance, to obtain the loading capacity of carriage.Due to Hall switch sensor output digit signals, simulation is overcome
The shortcomings that signal is decayed, improves the stability and high reliablity of elevator.It is further improved, is arranged between interior chassis and outer chassis
There is resilient cushion, increases the comfort of elevator.
The beneficial effects of the present invention are: apparatus of the present invention are skillfully constructed, structure is simple, installation and debugging are convenient, stability and
High reliablity.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
With reference to the accompanying drawing, the present invention is described in detail.
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Embodiment: as shown in Figure 1, a kind of elevator weighing apparatus, including lift car, elevator control system and sensor 1,
The elevator control system and sensor 1 connect, and are provided with first switch frame 3, elevator car on the interior chassis 2 of the lift car
Second switch frame 5 is provided on the outer chassis 4 in compartment, the sensor 1 is arranged on second switch frame 5, the first switch frame 3
On be provided with magnet steel 6, the magnet steel 6 is relative to 1 right angle setting of sensor.The sensor 1 is Hall switch sensor.It is described
Resilient cushion 7 is provided between interior chassis 2 and outer chassis 4.
The adjustment of distance between magnet steel and sensor: when elevator volume carries, magnet steel is placed in the front of sensor, significant surface
The front of alignment sensor, the position for adjusting sensor export it just, lock sensor screw, and volume carries adjustment and finishes.
