At present, the test of lifting machine is really doing the test to a plurality of motors, and a plurality of motors just have different voltage and different power, then need match a plurality of automatically controlled cabinets, and the cost of manufacture of automatically controlled cabinet is very high, and artifical consuming time is many when the motor is changed, needs artifical timing when the motor moves, and the record is inaccurate, and artifical consuming time is many.

Disclosure of Invention

The utility model discloses to the above background of saying, the problem that will solve provides the power plug of the motor that can make things convenient for, change different voltages safely, and the long device of accurate record operation, and the man-hour loss that can effectual reduction tester change the motor reduces the cost of manufacture of automatically controlled cabinet, and it is long when showing the motor operation on the touch-sensitive screen simultaneously, and tester can clearly and definitely know motor life, reduces the potential safety hazard of equipment.

The utility model provides a technical scheme that above-mentioned problem adopted does:

the device comprises a PLC, a touch screen, an emergency stop button, a buzzer, a power selection knob, a power indicator, a motor starting knob, a motor circuit breaker, a power control contactor, a motor control contactor, a switching power supply, a relay, a phase sequence protector, a safety lock and a rectifier; when the power supply of the utility model is switched, two different power supplies have the interlocking function, only one power supply can be used, the power supply indicating lamp corresponding to the power supply rotary switch is turned on to give the prompt of the indicating lamp, the power supply selection error is avoided, two outlet plugs with different colors are arranged below the electric control cabinet, the replacement is clear, simple and convenient, after the power switch is controlled to be turned on, the power starting knob of the motor needs to be rotated again, thus avoiding the direct starting of the motor after the power is switched on, ensuring the safety of the motor, controlling the motor by the PLC next time, directly clicking the forward or reverse starting button of the motor by the input button on the touch screen, simultaneously, having the power-off record of the running indication lamp prompt and the running duration on the touch screen, the circuit has overcurrent protection and phase sequence protection of the motor, and if the circuit detects that the phase sequence has wrong output signals, the buzzer can give out sound intermittently. When the safety lock is in a locking state, the buzzer can intermittently make sound, the conditions of the power supply and the safety lock are judged according to the phase sequence protector and the buzzer, the running state of the motor is known according to the result recorded in real time by the PLC, and equipment analysis is carried out.

The testing device for the elevator is disclosed.

The switching power supply is used for providing a 24V direct-current power supply for the PLC.

The switching power supply provides 24V direct current power supply for the touch screen

The power supply selection knob is a 220V alternating current power supply which is connected with a coil of the power supply contactor.

The motor starting knob is a 220V alternating current power supply which is connected with a coil of a motor contactor.

The buzzer state indicator light is red and intermittently turned on, the red light and the sound are intermittently turned on to indicate that the circuit function is abnormal, and the touch screen green indicator light indicates that the motor is running.

The utility model has the advantages that: the connection is changed to the plug that only needs the power cord plug when changing the motor, and it is simple and convenient to change, can just change the completion after can not changing a plurality of electric cabinets, the suggestion of plug colour and the suggestion of pilot lamp when changing to there is the power interlocking function in the circuit, reduced the risk that the power inserted the mistake, improve equipment security performance, the long record of operation of touch-sensitive screen makes data more accurate, reduces tester operating time's loss, improves work efficiency simultaneously.
