The invention relates to the technical field of forest rescue equipment, and discloses an automatic control sudden stop rope pulley for forest rescue. The automatic control sudden stop rope pulley comprises a rotating part, permanent magnets are fixedly connected to two sides of the rotating part, a limiting groove is formed in the rotating part, a rotating shaft is connected in the rotating part in a sleeving manner, and control grooves are formed in the top and the bottom of the rotating shaft. First springs are fixedly connected to the inner sides of the control grooves, control blocks are fixedly connected to the outer sides of the first springs, and magnetic blocks are fixedly connected into the control blocks. According to the automatic control sudden stop rope pulley for forest rescue, through mutual cooperation of an electromagnet and the magnetic blocks, when the electromagnet is powered on, the control blocks overcome the elastic force effect of the first springs to enter the limiting groove, the rotating part 1 is clamped, meanwhile, a starting block makes contact with an electric contact ring, an electrode column is powered on, and an electrorheological fluid in a liquid cavity is changed into a solid state from a liquid state, so that locking of a fixed rod is realized, so that the rotating part stops rotating, the product stops moving on the rope, and the function of emergency stop is realized.
Description
technical field [0001] The invention relates to the technical field of forest rescue equipment, in particular to an automatic control emergency stop rope pulley for forest rescue. Background technique [0002] Forest fire is not only the most dangerous enemy of the forest, but also the most terrible disaster of forestry. It will bring the most harmful and destructive consequences to the forest, causing great loss of forestry resources and global environmental pollution. During the process of forest rescue In the process, it is often necessary to use ropes and pulleys to realize the rapid movement of rescuers near the fire site, but in the process of moving, people often collide and the speed exceeds the safe range, resulting in casualties, which is not conducive to the use of users. [0003] When rescuers use ropes and pulleys to move, the gravitational potential energy of the rescuers is used to convert it into kinetic energy during the descent to realize movement on the ro...
