Control cabinet testing platform encoder single-phase single counting model

Abstract

The invention discloses a control cabinet testing platform encoder single-phase single counting model. The control cabinet testing platform encoder single-phase single counting model comprises a box body, a control unit, a standby power supply, a display unit, an alarm buzzer, a buffer unit and multiple moving wheels; the control unit comprises a traction motor, a high-speed counter, a turbine speed reducer, a traction inertia rope wheel, a coupling, a rotary encoder, a frequency converter, an alternating-current contactor, an electric leakage releaser, an inverter and a controller; the display unit comprises a RGB information display screen arranged in a first mounting area and connected with the controller for displaying an operating state of the model; the alarm buzzer is fixedly mounted at the outer top of the box body, and is connected with a controller; the controller drives the alarm buzzer to give an alarm; the buffer unit is positioned under the box body; and the multiple moving wheels are arranged at the bottom of a lower buffer plate. The control cabinet testing platform encoder single-phase single counting model has the advantages of reasonable structure, quick heat dissipation, stable operation and direct observation.

Description

technical field [0001] The invention belongs to the field of elevators, and relates to an elevator control cabinet test platform technology, in particular to a control cabinet test platform encoder single-phase single-count model. Background technique [0002] With the continuous improvement of modern people's material living standards, the scope of use of elevators has also continued to expand. The elevator control cabinet plays a decisive role in the normal operation of the elevator. Therefore, the control cabinet and its internal components such as encoders, controllers, counters and other components play a decisive role. The normal operation of the elevator guarantees the operation of the elevator. The use of the encoder is mainly by programming and converting the signal or data into a signal form that can be used for communication, transmission and storage. It is usually connected to the traction motor in a rotating way. When the traditional encoder is running, a large ...

[0002] With the continuous improvement of modern people's material living standards, the scope of use of elevators is also expanding. The elevator control cabinet plays a decisive role in the normal operation of the elevator. Therefore, the control cabinet and its internal encoders, controllers, counters and other components The normal operation of the elevator has brought guarantees to the operation of the elevator. The use of the encoder is mainly to compile and convert the signal or data into a signal form that can be used for communication, transmission, and storage. It is usually connected to the traction motor in a rotating manner. Connection, when the traditional encoder is running, a large amount of heat energy will be generated when the electrical appliances inside the control cabinet are running, and this heat cannot be eliminated, resulting in damage to the encoder and other electrical appliances inside the control cabinet due to excessive heat. Due to the high frequency of elevator up and down, the traditional encoder control cabinet lacks decompression and buffer components, resulting in extremely unstable operation of the control cabinet and the internal encoder, which is easy to cause damage to electrical appliances, etc. The lack of moving components makes the encoder And the control cabinet becomes very troublesome in the process of moving and handling before and after use
