Description

Technical Field

[0001] The utility model relates to an escape device for trapped persons in dangerous situations such as aerial work, sports and fire in high-rise buildings, belongs to the technical field of high-altitude emergency life-saving, and is a safe high-altitude emergency life-saving slow-descent device. Background Art

[0002] With the continuous progress of society, there are more and more high-rise buildings. For the construction, maintenance, cleaning and other work on the exterior walls of high-rise buildings, professionals must use professional hanging baskets or operating platforms to fix them at a certain height for operation, and then gradually descend to the next operating height after completion, and finally return to the ground; from the perspective of life-saving, hotels, inns and residents of high-rise buildings need emergency means of escape when a fire occurs and the exit is blocked or they are blocked indoors by criminals. The common slow-descent life-saving devices on the market can be used for the above-mentioned aerial operations, transportation and life-saving, but they still need to be greatly improved in terms of simplicity, reliability and safety and reliability.

[0003] The Chinese patent document with announcement number CN206315370 U (application number CN2016214671858, published on July 11, 2017) discloses a high-altitude controllable slow-descent escape device, the technical solution of which includes a rope-releasing shaft, a rope-collecting shaft, a control wheel, and a suspension rope. Both the rope-releasing shaft and the rope-collecting shaft can rotate along their axial direction, and the two shafts are driven to release and collect the rope through the mutual transmission of gears, so that one shaft releases the rope while the other shaft collects part of the suspension rope, and the descent speed is controlled by manually pulling the rope. However, this high-altitude controllable slow-descent escape device has the following two shortcomings: 1. The structure is complex, there are many parts, the manufacturing is labor-intensive and time-consuming, and the materials used are large, and the cost is high. 2. The descent speed needs to be controlled manually. It is clamped suddenly during deceleration, and the speed has a sudden change process. This makes it difficult for the operator's body to withstand the sudden impact force. In addition, due to the high mental tension of the user during the escape process, operational errors may occur, causing safety hazards. Therefore, it is necessary to optimize and improve various types of high-altitude slow-descent escape devices. Utility Model Content

[0004] The main purpose of the utility model is to provide a slow-descent life-saving device to address the deficiencies of the prior art and to meet the practical needs of achieving safe descent from a height or staying in the air in aspects such as aerial work, tourism, sports and life-saving.

[0005] The principle on which the utility model is based is as follows: the landing device of the utility model adopts a rope-releasing drum and a rope-collecting drum, the rope-releasing drum is coaxial with the rope-collecting drum and is made into a whole along the axis direction of the two, the diameter of the rope-releasing drum is more than three times larger than the diameter of the rope-collecting drum, the landing device and the hanging device are connected by a suspension rope, and two hanging drums are respectively connected with a fixed rope and a fixed ring, the fixed ring is connected with a safety belt, and the safety belt is fixed on the person who needs to descend. Since the suspension rope bypassing the fixed pulley above the rope-collecting drum is respectively located on the two sides of the axis of the rope-releasing drum and the rope-collecting drum, and the head end and the tail end of the suspension rope are respectively fixedly connected to the rope-releasing drum and the rope-collecting drum, therefore, the tension of the suspension rope is respectively located on the two sides of the axis of the rope-releasing drum and the rope-collecting drum, and the combined force of the suspension rope tension on the two sides is balanced with the downward gravity of the descending person, thereby bearing the entire weight of the descending person and the landing device. When the descending personnel rotate the handles on baffles 1 and 3 in a certain direction, the rope can be gradually moved downwards because the length of the rope released by the rope-releasing drum is much longer than the length of the rope wound by the rope-collecting drum. Once the handles are stopped, the rope will be stationary, so that the descending personnel will also be suspended. Controlling the speed of rotating the handles can control the speed of the rope moving downwards, so that the personnel can gradually descend to the ground.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a speed-controlled high-altitude personnel slow descender, including a descending device and a hanging device, the descending device including a rope-releasing drum, a rope-collecting drum, a central axis, and a hanging drum; the central axis penetrates the hanging drum, the rope-releasing drum, the rope-collecting drum and the hanging drum in order from left to right; the hanging drum is movably connected with the central axis; the rope-releasing drum is coaxial with the rope-collecting drum and is made into a whole along the axial direction of the two, the diameter of the rope-releasing drum is more than three times larger than the diameter of the rope-collecting drum, baffle plate 1 and baffle plate 2 are arranged on both axial sides of the rope-releasing drum in order from left to right, baffle plate 3 is arranged on the right side of the rope-collecting drum away from baffle plate 2, and a plurality of rotating handles are evenly fixed on the radial outer ends of baffle plate 1 and baffle plate 3; fixing screws are used in the rope-collecting drum to connect the rope-releasing drum, the rope-collecting drum and the central axis.
