Abstract
The invention relates to a hydraulic damping high-rise escape descent control device which consists of a drum wheel (1), a wire rope (2), an overrunning clutch (3), a hydraulic damper (4), a shell (5), a hoisting mechanism (6) and an escape descent control device fixing member (7). When a fire breaks out in a high-rise building, and all exits are closed off by the fire, the men in the scene of a fire have to take the way of escaping from windows or balconies into consideration, the device provided by the invention enables the men to decline slowly in the process of high-rise escape so as to prevent the men from injuries, and the hydraulic damping escape descent control device is used as a resistance source for the wire rope, so that the men can decline slowly in the process of escape; and the device has the advantages that the structure is simple and the descent velocity is not proportional to the hanging gravity, so that whether children or adults, one or two men are hung on the wire rope, a relatively stable descent velocity can be obtained, thereby providing an escape shortcut for the distress callers in the scene of a fire.
Description
Art skill field
The invention of this reality relates to a kind of Hydrautic damping skyscraper escaping descent control device.
Background technology
Along with nearly rapid development of economy decades of China, people's living standard and quality of life have had great improvement, and increasing people has broken away from poverty, has gone up the auspicious day excessively.People's housing condition has also had very big improvement, and increasing people has moved the building inhabitation to from one-storey house.The urbanization process of China develops very soon, and various skyscrapers emerge in large numbers one after another in the every nook and cranny in the whole nation, for motherland has increased the beautiful landscape of a lot of.Yet the worry that is accompanied by the appearance puzzlement people of a large amount of skyscrapers also can be comed one after another, and fire of high-rise building is exactly wherein a kind of.In case people's escape had often just become problem when skyscraper breaking out of fire, all outlet ports were all shut by big fire, how leaving the scene of a fire as early as possible is the key factor that the person for help is able to survive.There are some escaping descent control devices to occur in the market; Yet the resistance that these escaping descent control devices generally adopt the method for mechanical grip steel wire rope that steel wire rope to be descended, performance are extremely unstable, and wire rope hanging is light, and the people is unable to come down; Hang and weighed and to have glided fast, the just easy tumble injury of people.
Summary of the invention
The present invention proposes a kind of design of Hydrautic damping skyscraper escaping descent control device to above-mentioned deficiency; Its principle is such: with steel wire rope on rolling wheel; One side wheel shaft of rolling wheel connects rope hoisting mechanism another side wheel shaft and is installed on the half-clutch device of freewheel clutch; The half-clutch device of another of freewheel clutch is installed in an end of hydraulic damper, and the other end of hydraulic damper is connected with the shell of descending lifeline.In case when the breaking out of fire people need escape, only need the escaping descent control device fixed component is fixed, health hung on steel wire rope got final product again toward gliding.When human body hang behind the steel wire rope owing to be closure state under the situation of freewheel clutch in forward rotation, at this moment hydraulic damper will slowly rotate rolling wheel through the velocity of rotation that freewheel clutch limits rolling wheel, reaches the purpose that the survivor slowly descends; People above after the personal security of front arrives ground pass through rope hoisting mechanism with the steel wire rope backrush to rolling wheel; Because will be in released state during the freewheel clutch counter-rotation; At this moment hydraulic damper no longer limits the rotation of rolling wheel, hoisting mechanism just can be easily with the steel wire rope backrush to rolling wheel.Hydraulic damper then is to use the principle of rocker slider; The rotation motion of rolling wheel is changed to the back and forth past moving of hydraulic damper piston; And the inner liquid medium of hydraulic damper flows between the two parts separated by piston and connecting pipe, coming and going under the effect of piston, and the speed that liquid medium flows depends on the adjusting situation of choke valve on the connecting pipe.When freewheel clutch is closed, just the velocity of rotation of rolling wheel can have been regulated like this as long as regulate the flow of choke valve.
Characteristics of the present invention are: have simple in structure; Easy to use; The decrease speed discord is hung the advantage that gravity is directly proportional; No matter no matter be child or adult, be that a people or two people hang on steel wire rope and all can obtain metastable decrease speed, for being in person for help in the scene of a fire shortcut of an escape is provided.
