CN-224212152-U - Terminal detection device of electric pipe coiling device

Abstract

The Hall sensor detects the magnetic signal and sends an instruction to the MCU to control the motor to slow down or stop running. The non-contact ranging scheme can be accurately adapted to flexible tubular objects with different diameters in real time, and damage to the remote control assembly is effectively prevented by means of early deceleration or stopping. The system monitors working current synchronously in the motor deceleration process, and immediately cuts off power when detecting that the instantaneous current exceeds a safety threshold, so that a remote controller assembly is protected, and excessive stretching of a pipe is avoided. The magnetic part is a soft magnetic ring, can flexibly adapt to the coil pipe requirements of various pipe diameters and materials, and remarkably improves the universality and the maintenance convenience of the equipment.
