Description of the embodiments
In order that the utility model may be more readily understood, a more particular description thereof will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Fig. 1 is a schematic circuit diagram of a transmission stop interlock system according to an embodiment of the present utility model. The system comprises a speed measurement control module, a relay module, an alarm module, a power module and interlocking equipment.
Specifically, the speed measurement control module is used for measuring the rotating speed of the motor docking equipment or the docking coupler. Meanwhile, a rotation speed threshold value is preset in the speed measurement control module. The speed measurement control module is also used for comparing the measured rotating speed with a preset rotating speed threshold value. When the rotating speed is lower than the rotating speed threshold value, the control signal is output, so that the interlocking equipment stops operating.
The alarm module is used for giving an alarm when the rotating speed measured by the speed measuring module is lower than a rotating speed threshold value, and reminding operators of processing as soon as possible.
In this embodiment, the alarm module includes an audible and visual alarm HA.
The power module is used for supplying power to the system. Referring to fig. 1, in this embodiment, the power module converts 220V ac power to 24V dc power and then supplies power to the speed measurement control module. The positive pole of the power module is connected with the Vcc end of the speed measurement control module, and the negative pole of the power module is connected with the com end of the speed measurement control module.
The relay module includes a relay coil and relay contacts. Referring to fig. 1, one end of a relay coil KA is connected with an OUT end of an A1 speed measurement control module, and the other end A2 of the relay coil KA is connected with a negative electrode of a power supply module. When the rotating speed measured by the speed measuring control module is lower than a set rotating speed threshold value, the OUT end of the speed measuring control module outputs high level, so that the relay coil is electrified.
The relay contact comprises a normally open contact and a normally closed contact of the relay. The normally closed contact is connected in a power supply loop of the interlocking device. When the relay coil is electrified, the normally closed contact is disconnected, so that a power supply loop of the interlocking equipment is disconnected, the interlocking equipment stops running, and equipment and personal safety accidents are prevented.
The normally open contact KA of the relay is connected in a power supply loop of the alarm module. When the relay coil is electrified, the normally open contact KA is closed, so that a power supply loop where the alarm module is positioned is conducted, and the alarm module can work normally.
In this embodiment, the model of the speed measurement control module is ZNZS2-6E1R.
Therefore, the technical scheme of the utility model judges whether the coupler pin or the nylon rod is broken or damaged by detecting the rotating speed of the motor butt joint equipment or the butt joint coupler, and automatically cuts off the power supply loop of the interlocking equipment when detecting that the rotating speed is lower than a preset rotating speed threshold value, thereby ensuring that the interlocking equipment stops running and further preventing equipment and personal safety accidents.
In addition to the above embodiments, the present utility model may have other embodiments; all technical schemes formed by equivalent substitution or equivalent transformation fall within the protection scope of the utility model.
