Emergency auxiliary limiting mechanism for winch

The emergency auxiliary limiting mechanism is characterized in that a winch body is rotatably mounted between a first side plate and a second side plate, an electromagnet is fixedly mounted on the inner side of the first side plate, a speed reduction block is slidably mounted on the inner side of the first side plate, a magnet plate is fixedly mounted on the outer side of the speed reduction block, and a limiting plate is mounted on the outer side of the magnet plate. A hydraulic cylinder is fixedly installed on the outer side of the second side plate, a mounting plate is fixedly installed on an output shaft of the hydraulic cylinder, an inserting rod is integrally formed on the mounting plate, the inserting rod and the inserting hole are correspondingly arranged, and when the winch is out of control, the electromagnet on the first side plate is powered on, and the hydraulic cylinder on the second side plate is started at the same time; the speed reduction block can be popped out under the action of the magne
