Description
Technical field:
This utility model belongs to lifesaving appliance field, particularly to a kind of high-rise building escape device.
Background technology:
Along with the development of China's economic society, the material life of people obtained and was greatly improved, and high-frequency fire incident also gets more and more.Solve current high building fire fighting hidden danger to bring into schedule, wherein fire in high buildings be that a kind of occurrence frequency is high, involve a wide range of knowledge, rate of propagation is fast, destructive big, rescue and the accidental pollution event of difficulty of escaping.How catching fire suddenly at high building, elevator can not use, and stair and passway for escaping are because of the intensity of a fire and smog obstruction, and in the case of can not flying Shang Qu also to jump to get off, the rapid safe escape of trapped personnel is the difficult problem that needs crack.Having a kind of mechanical electric dynamic formula escape device at present, this escape device needs power supply to provide power, also needs to mechanical transmission mechanism simultaneously and carries out the slow fall of speed change.Can the most this escape device power supply when disaster occurs reliably use is a big problem, and secondly this device complexity is huge, and cost is high, should not promote the use of.So, design and manufacture the high-rise building escape device that a kind of simple in construction is easy to operate, there is certain using value and good social benefit.
Summary of the invention:
The purpose of this utility model is to solve the problem that above-mentioned technology exists, a kind of high-rise building escape device of design, in case of emergency can help trapped personnel safe escape dangerous situation, drop to ground smoothly, effectively ensure the security of the lives and property of broad masses, be the essential product of people's home security.
In order to realize object above, agent structure of the present utility model includes that chain group, casing, actuating device and arrangements for speed regulation, described chain group comprise two chains being arranged in parallel；Having two chain cylindrical voids above described casing, box house is equipped with power transmission shaft and arrangements for speed regulation；Described power transmission shaft is divided into a driving shaft and a driven shaft, is arranged in parallel in casing；Described driving shaft left end is equipped with a gear, and middle equipped with two sprocket wheels being meshed with chain, right-hand member is equipped with band brake apparatus；Described driven shaft left end engages each other equipped with a gear the same with driving shaft, two gears, and right-hand member is equipped with a freewheel clutch；Described clutch outer is connected with band-type brake by steel wire rope；Described band-type brake is connected by the outer hand lever of steel wire rope and casing.
Escape personnel first pulls, after fastening the seat belt being fixed on casing, lever of stopping, then come up, now under the action of gravity of human body, casing ramps up decline, now sprocket wheel accelerates to rotate, driving shaft is driven to accelerate to rotate, gear on driving shaft is delivered to driven shaft by another gear engaged rotating speed, freewheel clutch on driven shaft plays speed governing effect, once the excessive velocities of driven shaft will give one pulling force of steel wire rope being connected with it, steel wire rope will act on the band brake apparatus on driving shaft, the speed allowing driving shaft lowers, thus ensure the slip of casing, speed controlling is about 1.5 meter per seconds, people is allowed to feel pleasant.
Compared with prior art, when high-rise building with fire disaster and other disasters, escape personnel can be from the position such as roof or window safe escape rather than sit back and wait fire-fighting and rescue for this utility model, it is possible to the autonomous best opportunity holding escape；It has feedback regulation function simultaneously, is a kind of closed-loop control device, and whole process need not human intervention, it is possible to realizes automatic speed regulation；Need not power supply, improve the reliability of device；Employing double-steel wire rope designs, and more can guarantee that the safe operation of device.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is freewheel clutch schematic diagram of the present utility model.
Labelling in figure: chain group 1, casing 2, hand lever 3, driving shaft 4, band-type brake 5, steel wire rope 6, freewheel clutch 7, clutch outer 7-1, steel ball ball 7-2, clutch inner ring 7-3, spring 7-4, driven shaft 8, gear train 9, chain wheel set 10.
Detailed description of the invention:
Below in conjunction with the accompanying drawings this utility model is further described:
Agent structure of the present utility model includes chain group 1, casing 2, hand lever 3, driving shaft 4, band-type brake 5, steel wire rope 6, freewheel clutch 7, clutch outer 7-1, steel ball ball 7-2, clutch inner ring 7-3, spring 7-4, driven shaft 8, gear train 9, chain wheel set 10；Described chain group 1 comprises 2 chains being arranged in parallel；Having two chain cylindrical voids above described casing 2, box house is equipped with power transmission shaft and arrangements for speed regulation；Described power transmission shaft is divided into driving shaft 4 and driven shaft 8, is arranged in parallel in casing；Described driving shaft 4 left end is equipped with a gear, and middle equipped with the chain wheel set 10 being meshed with chain group 1, right-hand member is equipped with band-type brake 5；Described driven shaft 8 left end engages each other become gear train 9 equipped with a gear the same with driving shaft 4, two gear, and right-hand member is equipped with a directional overrunning clutch 7；Described clutch outer 7-1 is connected with band-type brake 5 by steel wire rope 6；Described band-type brake 5 by steel wire rope with casing outside hand lever 3 be connected.
nullEscape program is: after fastening the seat belt on casing 2，Slowly loosen hand lever 3，Now casing 2 starts to accelerate to decline，Chain wheel set 10 is also accelerating rotation simultaneously，Driving shaft 4 is driven to accelerate to rotate，The rotating speed of driving shaft 4 is delivered to driven shaft 8 by gear train 9，Equipped with freewheel clutch 7 on driven shaft 8，Driven shaft 8 drives clutch inner ring 7-3 to accelerate to rotate，Clutch inner ring 7-3 throws a micro-section away steel ball ball 7-2 under the circumference of the high-speed rotation and moves，Now steel ball ball 7-2 carves tightly middle at clutch inner ring 7-3 and clutch outer 7-1 gap，Rotating speed is delivered to clutch outer 7-1 by clutch inner ring 7-3，Therefore clutch outer 7-1 pulls steel wire rope 6，Steel wire rope 6 pulls band-type brake 5 to realize automatic reduction of speed，And when speed drops too low when，Steel ball ball 7-2 resets under the effect of spring 7-4，Now clutch inner ring 7-3 contacts with the disengaging of clutch outer 7-1，Clutch outer 7-1 is in free state and reduces the braking effect of band-type brake 5，Thus rotating speed rises again，So move in circles and make by speed controlling in the ideal range，Personal security slowly drops to ground.
