AI Technical Summary

Technical Problem

In the current parking lot barrier gate, the rotating shaft is located at the right end of the gate arm during the opening process, which requires overcoming a large torque, resulting in a large motor load, high energy consumption, and easy damage to the equipment.

Method used

A counterweight is installed at the right end of the gate arm. The weight of the counterweight generates a torque to balance the resistance torque when the gate arm rotates. A multi-link linkage structure is used to transmit motion, reducing the power required by the motor.

Benefits of technology

By using counterweights to reduce motor load, energy consumption, and equipment lifespan, the system stability is improved, gate arm vibration and wear are prevented, and the safe operation of the equipment is ensured.
