Technical Field

[0002] The high-voltage switch electric chassis vehicle is a key piece of equipment used in high-voltage switchgear. It is mainly used to carry high-voltage electrical components such as vacuum circuit breakers, load switches, and instrument transformers, enabling them to be moved forward and backward within the switchgear.
[0003] Most existing high-voltage switchgear chassis require manual operation by staff. When staff pull out the chassis, the wheels on both sides of the chassis will move out of the track, thus removing the chassis from the cabinet. This greatly increases the labor intensity of the staff and makes it inconvenient for them to use. Utility Model Content

When the staff pulls out the chassis vehicle, the wheels on both sides of the chassis vehicle will move out of the track, thereby moving the chassis vehicle out of the cabinet, which greatly increases the labor intensity of the staff and is inconvenient for the staff to use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage switch electric chassis vehicle control device, comprising a frame, a mounting base fixedly connected to the front side of the frame, a handle fixedly connected to the front side of the mounting base, a mounting cavity formed at the bottom of the frame, a driven shaft rotatably connected to the rear side of the mounting cavity, driven wheels fixedly connected to both sides of the driven shaft, a connecting block fixedly connected to the middle of the mounting cavity, a Hall sensor fixedly connected to the right side of the middle of the mounting cavity, a servo motor fixedly connected to the bottom of the connecting block, a second pulley fixedly connected to the output end of the servo motor, a transmission belt provided on the surface of the second pulley, a drive shaft rotatably connected to the front side of the mounting cavity, a first pulley fixedly connected to the surface of the drive shaft, drive wheels fixedly connected to both ends of the drive shaft, a PLC controller fixedly connected to the left side of the mounting cavity, and a wireless signal transceiver fixedly connected to the left side of the mounting cavity.

[0008] By adopting the above technical solution, and by setting up a wireless signal transceiver, a PLC controller, and a servo motor for coordinated use, after the wireless signal transceiver receives information, the PLC controller will control the servo motor to start. The servo motor drives pulley two to rotate through its output terminal. Pulley two drives pulley one to rotate through a transmission belt. Pulley one drives the drive wheel to rotate through the drive shaft, thereby moving the vehicle body forward or backward, realizing the automatic movement of the chassis vehicle without the need for operator intervention, reducing labor intensity and making it convenient for operators to use.
[0009] Preferably, the position of the Hall sensor corresponds to the position of the servo motor, and the Hall sensor is located at the right end of the servo motor.
[0010] By adopting the above technical solution and using Hall sensors and servo motors in conjunction, the Hall sensors can collect the operating current value of the servo motor in real time. When the stall current is detected to exceed the protection threshold, the PLC controller will immediately execute the protection action to prevent the motor from being damaged by strong noise interference when running in a harsh electromagnetic environment, thereby improving its service life and making it convenient to use.
[0011] Preferably, both ends of the driven shaft pass through the inner wall of the frame and extend to the outside of the left and right sides of the frame.
[0012] Preferably, both ends of the drive shaft penetrate the inner wall of the frame and extend to the outside of the left and right sides of the frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This high-voltage switch electric chassis vehicle control device uses a wireless signal transceiver, a PLC controller, and a servo motor in conjunction. After the wireless signal transceiver receives information, the PLC controller controls the servo motor to start. The servo motor drives pulley two to rotate through its output terminal. Pulley two drives pulley one to rotate through a transmission belt. Pulley one then drives the drive wheel to rotate through the drive shaft, thereby moving the vehicle body forward or backward, realizing automatic movement of the chassis vehicle without the need for operator intervention, reducing labor intensity and making it convenient for operators to use.
[0014] 2. This high-voltage switch electric chassis control device uses Hall sensors and servo motors in conjunction.

[0019] Working principle: When in use, the operator sends a command to the wireless transceiver 15 through the terminal. After receiving the information, the wireless transceiver 15 sends the information to the PLC controller 14. The PLC controller 14 then controls the servo motor 12 to start.
