Cableway rescue pulley

Abstract

The ropeway rescue pulley comprises a main body square tube, an upper tube is installed on the outer side of the main body square tube through an upper tube shaft, the two ends of the main body square tube are slidably hoisted to the top of a rope through dragging cross rods, a brake assembly is installed on one side of the main body square tube, and safety rings are further installed at the positions, located at the bottoms of the dragging cross rods, of the two ends of the main body square tube. A passenger sits on the seat, the pulley slides along the rope, and when the passenger gets close to a target or wants to decelerate and stop, the brake handle is wrenched, the brake plate is adjusted to rise to press the rope through the brake connecting rod a, the brake connecting rod b and the brake connecting rod c, so that the brake plate rubs with the rope, the pulley is controlled to decelerate, and the purpose of decelerating or stopping is achieved through direct braking. When not used, the brake handle is loosened, the reset spring rod resets and loosens the brake due to the elastic force of the spring, and the situation that the service life of the rope is affected due to friction between the brake pad and the rope when the rope is not used is avoided.

Description

Technical Field

[0001] The invention relates to the technical field of pulley equipment, and in particular to a cableway rescue pulley. Background Art

[0002] In cableway rescue scenarios in complex terrains such as mountains and canyons, traditional rescue methods such as direct climbing with ropes or carrying with simple stretchers have many difficulties. For example, in some mountain cableway accidents, rescuers carry a lot of equipment and climb to the accident site on foot, which is not only inefficient but also consumes a lot of physical strength. At the same time, on steep slopes and complex terrain conditions, it is difficult to ensure the stability and safety of the rescue process using simple rescue tools. Traditional rescue tools are also powerless when facing long-distance, high-drop cableway rescue. For example, when the cableway span is large and the accident site is in the middle of the cableway, it is very difficult to move rescuers and the injured by simply dragging the rope by manpower, and it is easy to cause secondary injuries.

[0003] The current cableway rescue pulleys are relatively simple in design and have a single function. For example, their brakes are not sensitive enough, and it is difficult to accurately control the speed and stop position of the pulley when driving at high speeds or encountering emergencies.
