Description

Technical Field

[0001] The present invention relates to the technical field of emergency rescue, and in particular to an emergency rescue device. Background Art

[0002] The statistical analysis of zipline accident failures shows that the emergency events mainly include three situations: natural disasters, passenger injuries and passengers stranded at high altitude. Because the zipline is a non-powered special equipment, it relies entirely on inertia to slide down. Passengers stranded at high altitude is the most common emergency event of the zipline. If the rescue is not handled in time, it is very easy to generate social public opinion and bring negative impact to the scenic spot. If the pulley is blocked, the passenger is light in weight, wind resistance and other reasons cause the passenger and the pulley to stop in the middle due to the inability to slide to the next passenger station, it is necessary to rescue them and bring the trapped person from the trapped environment to a safe place. The existing rescue methods have the following disadvantages: 1. The rescue time is long. During the rescue process, rescuers often need to rely on experience to control and operate the equipment, which is labor-intensive. 2.
