The servo motor 2 is used to output rotation parameters to the controller. The displacement sensor 3 is used to collect the vertical movement position of the output end of the body 1 and output it to the controller. The present invention comprises a main body 1, a servo motor 2, a controller, and a displacement sensor 3, which together form a screw-type gate hoist.

[0050] As an optional implementation, in one embodiment of the invention, two synchronous pulleys and a transmission belt are further provided. The two synchronous pulleys are respectively connected to the input end of the main body 1 and the servo motor 2, and the two synchronous pulleys are connected by the transmission belt.

[0051] As an optional implementation, in one embodiment of the utility model, the servo motor 2 is an absolute servo motor, and the controller is a programmable logic controller (PLC). The absolute servo motor reduces mechanical impact by accelerating start-up and decelerating stop, and can actively adjust its output torque to regulate the tension or pressure on the lead screw, ensuring that the screw-type gate hoist does not operate under overload. Simultaneously, the absolute servo motor can actively adjust its output torque to regulate the tension or pressure on the lead screw according to actual working conditions, ensuring that the screw-type gate hoist does not operate under overload under various circumstances, thus improving stability and reliability. The PLC has data processing and control functions, acquiring the rotational position information of the servo motor 2 in real time.

[0052] This utility model embodiment also provides a gate control system, which includes the aforementioned screw-type gate hoist. The screw-type gate hoist is provided with a body 1, a servo motor 2, a controller, and a displacement sensor 3. The output end of the body 1 is connected to the gate. The servo motor 2 is disposed on one side of the body 1 and connected to the input end of the body 1. The controller is electrically connected to the servo motor 2. The displacement sensor 3 is disposed on one side of the body 1 and electrically connected to the controller. The controller is used to control the rotation of the servo motor 2 to drive the output end of the body 1 to move vertically up and down. The servo motor 2 is used to output rotation parameters to the controller. The rotation parameters include speed and position parameters. The displacement sensor 3 is used to collect the vertical movement position of the output end of the body 1 and output it to the controller. The present invention comprises a main body 1, a servo motor 2, a controller, and a displacement sensor 3, which together form a screw-type gate hoist. After acquiring the rotation parameters of the servo motor 2, the controller calculates the theoretical position of the gate based on the preset transmission ratio and the lead of the output end of the main body 1. The displacement sensor 3 transmits the actual position information of the vertical movement of the output end of the main body 1 to the controller. The controller receives the theoretical and actual position information of the gate and compares them, calculating the difference. When the difference is within a preset range, the elastic deformation of the output end of the main body 1 is within the allowable threshold. When the difference exceeds the preset range, the elastic deformation of the output end of the main body 1 exceeds the allowable threshold, resulting in permanent bending damage. The screw-type gate hoist promptly detects the elastic deformation of the output end of the main body 1 and determines whether it exceeds the allowable threshold, so as to respond and handle it in a timely manner, stop the machine or perform maintenance, thereby ensuring the reliable operation of the screw-type gate hoist and improving the safety of its operation.
