Description
Technical Field
The invention relates to a slow descending tool, in particular to a safe and reliable slow descending bag, and belongs to the technical field of fire fighting and sports equipment.
Background
At present, high buildings in cities are spread all over, people are dense, and people are urgently required to rapidly escape from the site when encountering fire, explosion and terrorist attacks, so that self-help escape and fire rescue technologies and equipment are particularly important for ensuring the life safety of people. In dangerous outdoor sports such as mountaineering, rock climbing and cliff speed reduction, slow descent equipment is also needed to ensure personal safety. Sometimes, natural disasters such as avalanche, torrential flood, earthquake, debris flow and the like exist, and fire rescue technologies and equipment are urgently needed for rescue and self rescue.
At present, various descent control devices have been proposed. The descent control device is arranged at a building window, a balcony or a flat top and the like, consists of a hook, a safety belt, a rope, a speed controller and the like, and is a self-rescue escape and rescue device which can make people slowly descend along the rope. Application number is 200920247602.1's utility model patent, provides a ware slowly falls to simple and easy friction formula, including wire rope handling hole, frame and friction post, simple structure can independently control the speed that descends, also can be used to the escape and the rescue of high building personnel through drawing the rope to control the speed that descends by following people. The invention patent with the application number of 201710590315.X also provides a quick-falling high-altitude escape intelligent backpack and an alarm implementation method thereof.
In the current descent control technology, a rope is wound on a winding wheel in a descent control device shell or a backpack, potential energy of a human body is converted into heat energy and kinetic energy of rotating parts through friction or damping of a speed controller, the temperature inside the descent control device is inevitably increased, metal fatigue and deformation are easily caused, mechanical faults such as fracture and blockage even occur, the service life of the descent control device is shortened, and timely detection is needed. At present, a descent control device with a rope suspended in the air can take away friction heat in time, but the rope is easily damaged by fire, oil and water pollution, liquid corrosion, foreign object winding, blockage and the like, mechanical performance of the rope is changed, even movement disorder is caused, and risks are brought. Therefore, the rope wound in the descent control device can generate heat, but can be prevented from being damaged; the rope hangs aloft and is vulnerable, but is convenient for heat dissipation, and the technical contradiction exists. In order to improve the safety and reliability of the descent control device and avoid the situation that the current descent control technology needs to solve the technical contradiction, improve and optimize.
Various descenders have been proposed. The descender strengthens the buffering effect by increasing the friction force on the rope, thereby achieving the purpose of descending at a low speed, and being used for expanding training, extreme sports, outdoor sports and protecting rescue workers and trapped people in rescue. The invention patent with application number 201711285325.9 provides a self-locking descender which is provided with a handle and a cam, can be clamped on a rope, can be used for outdoor exercises, rescue and high-altitude operation, can be anti-panic and avoids the risk of careless descent. Compared with a descent control device, the descent control device does not need to contain a rope, is light in weight, simple in structure, small in size, convenient to control and good in heat dissipation, and needs professional training; psychological panic is easily caused when the medicine is used for the first time.
At present, ropes for high-altitude escape, rescue, outdoor sports and high-altitude operation are various, and include safety ropes, climbing ropes, rescue ropes, safety ropes and the like. These ropes are commonly provided with a core in the centre and a sheath on the surface. The rope core mainly bears the tensile force and is made of steel wires, nylon fibers or other synthetic fiber materials. The sheath may have multiple layers, requiring wear resistance, water resistance, corrosion resistance, flame retardancy or insulation, and is generally woven from synthetic fiber materials.

The descender 7 is fastened on the main rope 2, is hung on the main safety belt 5 at the lower end through a safety hook, can bear the gravity and impact force of a wearer 8, slowly descends, and can be at least used for high-altitude escape, rescue, outdoor sports and high-altitude operation.
The invention has the following beneficial effects: (1) the slow-descent bag can be worn in front of the chest of a wearer 8 through the main safety belt 5 and the auxiliary safety belt 6 during high-altitude escape, rescue, outdoor exercises and high-altitude operation. When the main rope 2 and the auxiliary rope 4 are wound inside the bag body 1, the whole body of the bag body is in a ring body shape, and the main rope and the auxiliary rope can be mutually bonded or bonded on the inner surface of the bag body 1, so that smooth drawing is ensured. Compared with the descent control device with a reel in the prior art, the descent control bag has no relative movement part or rotating part in the bag body 1, does not generate the rotating kinetic energy of the rotating part when the main rope 2 and the auxiliary rope 4 are drawn out, does not generate heat due to friction, can avoid the mechanical faults of breakage, blockage and the like of the rotating part, ensures smoothness, and is safer and more reliable. In addition, the slow descending bag has no relative moving parts in the bag body 1, so that the space is saved, the weight is lighter, and the slow descending bag is convenient to carry, store and store.
(2) In the invention, the sheaths of the main rope 2 and the auxiliary rope 4 are formed by obliquely and crosswise weaving twisted strands, a velvet surface belt and a hook surface belt, so that the main rope 2 and the auxiliary rope 4 can be mutually bonded when being wound in the bag body 1, and can be smoothly drawn out. The prior art ropes have no adhesive force between the ropes, because uncertain factors such as uneven twist of the plied yarns, uneven integral twisting, vibration and the like, the ropes can be staggered with each other during winding, and the rope rings are staggered, so that other rope rings are easily driven and clamped during drawing, knotting and blockage are caused, and potential safety hazards exist. Compared with the existing ropes such as mountain climbing ropes, rescue ropes, safety ropes and the like, the main rope 2 and the auxiliary rope 4 can be mutually bonded and fixed in relative positions during winding, and mutual dislocation is avoided, so that smoothness can be ensured during drawing, and disorder, knotting and blockage can be avoided. In addition, the fluff of the fluff surface belt and the fluff of the hook surface belt on the surfaces of the main rope 2 and the auxiliary rope 4 can increase the friction area when moving relative to the descender 7, so that more air flows, the heat dissipation is convenient, the temperature rise of the descender 7 can be reduced, and the service life of the descender 7 is prolonged.
(3) The slow descending bag is worn in front of the chest of a wearer 8, and carrying of the backpack is not affected. Compared with the slow descending device in the prior art, the slow descending device at least can be used for high-altitude escape, rescue, outdoor sports and high-altitude operation, and has wide application and convenient operation.
(4) When the slow descent bag is stored, the slow descent bag can be folded and stored in the light, thin and soft protective bag 3, so that the space is saved, and the slow descent bag is convenient to carry, store and store; when the bag is worn, the bag body 1 can be directly pulled out of the protective bag 3, the protective bag 3 can naturally drop in front of the chest of a wearer 8, the wearing operation is fast, and the wearing is comfortable.
