Problems solved by technology
[0005] It can be seen that the bite between the crossing device and the rope is very important. If the bite is not firm, the accident of rescuers falling may occur; but if the bite is too tight, the friction between the crossing device and the rope will increase. It reduces the difficulty of sliding, consumes the energy required for sliding, and reduces the efficiency of sliding

The invention discloses a spiral rope-grabbed active crossing device and an application method. The device is provided with a driving rod driven by a rotating mechanism and rotated around self long axis; a first roller mechanism, a roller and a second roller mechanism are arranged on the driving rod; and the roller is fixedly connected with the driving rod, and is rotated along with the driving rod. The active crossing device is hung on a rope through fixed rollers arranged at the upper ends of the roller mechanisms; and the rope is spirally wound on the roller. Only the rotating mechanism isneeded to drive the driving rod to rotate in use, and the roller is driven to rotate; and the rope is driven to move through static friction force so as to realize the crossing movement of the activecrossing device along the rope. In the active crossing device, through arrangement of the roller, the rope is spirally wound on the roller by at least one lap, so that the static friction force of therope and the active crossing device is increased, the slippage or fall accident is not easily generated in the suspension crossing movement, and the crossing operation safety is guaranteed.
Description
technical field [0001] The invention relates to the technical field of fire-fighting and rescue appliances, in particular to a spiral rope-grabbing type active crossing device and a use method thereof. Background technique [0002] In the rescue of large-span and large-space disasters such as canyons, rivers, high-rise buildings, and flood rescue, rescue officers and soldiers may not be able to directly reach the location of the person in distress. way and way of rope crossing. In canyon or river rescue, bridge rescue can also be quickly erected, which has strong evacuation capabilities, but the erection operation is complicated, time-consuming, costly for equipment, and not suitable for rapid waters. Usually, the rapid bridge rescue method is only applicable to waters with slow flowing water, and a very small number of severe flood disasters or accident sites. When there are a large number of people who need rescue and evacuation, quickly build a rescue channel. [0003] ...
