Abstract
A kind of constant speed type descending lifeline, adopts novel escapement to control the rotating speed of descending lifeline drive disk assembly, thus reaches the order ground of human body uniform descent; Constant speed type descending lifeline is made up of auxiliary members such as pressing from both sides rope wheel component, Gear Planet Transmission train, escapement assembly and upper bottom plate; It is isosceles triangle that Wield in escapement indulges the gear teeth, and the number of teeth can change at 6-12 between cog, and the upper and lower two ends of escape wheel are furnished with roller type slip assemblies.The present invention be to provide a kind of reliability high, control human body decrease speed constant, not water funk, be not afraid of oil, when depositing by the constant speed type descending lifeline of extraneous various ambient influnence.
Description
(1) technical field
The present invention is a kind of constant speed type descending lifeline, belongs to fire-extinguishing and lifesaving equipment.
(2) background technology
The fire disaster escaping descending lifeline of single use in the world at present, all adopts centrifugal friction mechanism to reach with controlling the order of escape human body uniform descent.The shortcoming of this mechanism is: the different decrease speed difference of human body weight is large, this failure mechanisms of the spilled oil that gets wet, descending lifeline deposits non-metallic friction materials moisture-sensitive on middle centrifugal friction block, aging, chemistry volatilization gas and dust all can make coefficient of friction change, and all cause casualty accident to user both at home and abroad in the demonstration of descending lifeline with in using because friction mechanism loses efficacy.So there is the problem of reliability, security in the descending lifeline used now always.
Be order of the present invention a kind of reliability of design high, control human body decrease speed constant, not water funk, be not afraid of oil, when depositing by the constant speed type descending lifeline of extraneous various ambient influnence.
(3) summary of the invention
For achieving the above object, the present invention adopts novel escapement to the Gear Planet Transmission train controlled in descending lifeline and the rotating speed pressing from both sides rope assembly, thus reaches the order ground of human body uniform descent, constant speed type descending lifeline is made up of auxiliary members such as pressing from both sides rope wheel component, Gear Planet Transmission train, escapement assembly and upper bottom plate, folder rope wheel component is formed by alloy-steel plate stamping riveting, indulges mechanism's one side be fastened with three planetary gears towards Wield, the ring gear of Gear Planet Transmission train is made by alloy-steel plate punching press, and multilayer is riveted into and is integrated, the central gear of Gear Planet Transmission train is fastened on escape wheel, it is isosceles triangle that Wield in escapement indulges the gear teeth, the number of teeth can change between 6 tooth-12 teeth according to rotation speed requirements, the upper and lower two ends of escape wheel are furnished with roller type slip assemblies, roller type slip assemblies is by roller, upper lower plate, roller shaft, counterweight, riveting axle forms, and by riveting axle, roller shaft is fastened as a whole, middle part has rotary hole, this roller type slip assemblies can according to the rotating speed needing to control, moment etc. require to select 1-4 group configuration, ring gear is fastening by upper bottom plate by riveting post, and be positioned at two fixed head centre positions, folder rope wheel component, central gear, upper bottom plate center all have hole to be passed through for central shaft, and escape wheel also rotates centered by this axle, is fastened with plastic casing dust-proof outside upper bottom plate, steel wire rope for carrying human body weight is fixed by pressing from both sides rope sheave, can rotate with folder rope sheave both forward and reverse directions, complete and move up and down function, rope two ends are fixed with the safety belt of fastening human body, during use this steel cable one end land after the other end be just in time back to upstairs starting point for another user escape, the steel wire rope two ends of fixing human can the rope of fastening random length, can for people's handled easily of different floor.
After adopting novel escapement, the control assembly of descending lifeline makes moist, aging, be stained with the skidding out-of-control phenomenon that wet goods causes and be solved, all transmission mechanisms and the even employing alloy steel material of parts manufacture, minimum by ectocine in depositing, and make its reliability, security significantly improves.
(4) accompanying drawing explanation
Fig. 1 is the structure sectional view of constant speed type descending lifeline detailed description of the invention of the present invention.
(5) detailed description of the invention
Constant speed type descending lifeline shown in Fig. 1 by pressing from both sides rope wheel component (10), Gear Planet Transmission train, escapement assembly and upper mounted plate (18), bottom plate (6), plastic casing (3) form.Two plastic casings are fastened on two fixed heads by screw (16), planetary gear (5) in Gear Planet Transmission train is fastened on the one side of folder rope wheel component (10) towards escapement with its turning cylinder, planetary gear (5) engages with ring gear (4) centre wheel (8), centre wheel (8) is fastened on escape wheel (11) center, the hole passed through for central shaft (15) is had in the middle part of centre wheel, made by alloy-steel plate punching press, multilayer is riveted into the ring gear (4) be integrated and is fixed by upper bottom plate by multiple riveting post (7), and be positioned in the middle part of two fixed heads, it is the folder rope wheel component (10) of alloy-steel plate stamping riveting below it, this folder rope sheave can prevent steel wire rope (9) from sliding in race, ring gear (4) top is escapement, escape wheel (11) tooth is isosceles triangle, be convenient to positive and negative rotation, the number of teeth can change at 6-12 between cog according to rotation speed requirements, the upper and lower two ends of escape wheel are mounted with roller type slip assemblies (2), this assembly is by roller (14), upper lower plate (12), counterweight, roller shaft and riveting axle composition, and by riveting axle, roller shaft is fastened as a whole, roller is rotatable, rotary hole is had in the middle part of this assembly, and be sleeved on the fixed axis (17) between upper mounted plate and ring gear, roller type slip assemblies can according to the rotating speed needing to control, moment etc. require to select 1-4 group configuration.Folder rope wheel component and the fastening escape wheel of central gear is even is sleeved on central shaft (15), central shaft two ends are fixed spacing by upper bottom plate.
During use, by the suspension member be fastened on the bolster stake (1) on upper bottom plate, constant speed type descending lifeline is fixed, safety belt (13) is inserted on human body, by steel wire rope rotating clip rope wheel component (10) in escape personnel's decline process, when planetary gear rotates around centre wheel, centre wheel speedup is rotated, the escape wheel (11) fastening with it then with centre wheel synchronous axial system, roller (14) in escape wheel teeth and roller type slip assemblies (2) collides, pushing rolling wheels formula slip assemblies rotates backward, escape wheel teeth is collided with second roller (14) again, continuous collision in rotation makes the rotating speed of escape wheel be controlled, thus control the rotating speed of folder rope sheave, reach the order ground controlling escape personnel's constant-speed descending.
