Description
Technical field
The present invention relates to implement in the on-the-spot disaster accident occurring in a kind of applicable building or other high-altitudes the specialty descending lifeline of rescue and amateur oneself's relief in batches, also extensive applicable among the peoplely transport vertically downward and the operation purposes such as mansion outer wall operation for object of the present invention.
Background technology
Building multiple stratification and high stratification are the embodiments of modern civilization progress, also be the inexorable trend of Development of Urbanization, this just means that personnel, valuable facility and property are more and more concentrated, once breaking out of fire or other disasters, the difficulty of personnel escape and tissue relief constantly increases.In view of this, the product that the eighties just has one to be referred to as " fall-slowing device for rescuing from high building " in last century comes out, and people wish to utilize this instrument just can pass through window or balcony, realizes safe falling escape.Over nearly twenty or thirty year, the research of the each bound pair of Chinese society " descending lifeline " is very active, and by investigation in 2011, relevant invention and utility model patent item number exceeded 200, are sure to occupy the hat of countries in the world patent family.With regard to know-why, the design of different descending lifelines is all nothing but to create a kind of suitable damping, to contend with by rescue personnel's self gravitation, makes by deliverer with the safe landing then that declines of acceptable speed.The technology path of realizing damping mainly contains three kinds of mechanical damping, hydraulic damping and electromagnetic dampings.With regard to the descending lifeline of the circulation that comes into the market both at home and abroad, basic homogeneity is mechanical damping type.It is mainly to realize automatic uniform speed landing that descending lifeline designs successful key, and speed should be within the receptible safety speed scope of common people institute; Speed can also artificially independently be slowed down and be controlled even hovering; The product using as a kind of popular disaster prevention emergency, the advantages such as that good descending lifeline also should possess is simple in structure, with low cost, light, " non-maintaining " and hommization.At present, no matter be published patent of invention project or the descending lifeline product in market circulation, all fail to meet preferably above whole requirements.Although mechanical damping type descending lifeline brand popular on market is various, mainly comprise cam exert pressure damping control type and planetary gear speed automatic control type.Cam the simple in structure of damping control type of exerting pressure, but the absolutely not uniform descent of realizing; Planetary gear speed automatic control type is the main product of existing market, can realize theoretically uniform descent, but without the function of independently slowing down and controlling and hovering, and, planetary gear speed automatic control type generally uses internal gear, processing technology is had relatively high expectations, and cost is also affected naturally.A series of difficult problems such as descending lifeline involved in the present invention can more satisfactory ground technical solution, cost, reliability, both can meet the needs that the general common people save oneself and he rescues, and also can be used as a kind of police equipment and dropped into batch rescue action efficiently.Because the descending lifeline the present invention relates to has the function of flexible deceleration control and soft landing, also can cater to the needs such as industrial and mining enterprises and building fitting-out work, for object, longitudinally transport and mansion outer wall operation provide usage space widely vertically downward.The descending lifeline design the present invention relates to, for the descending lifeline national technical standard of the existing promulgation of round Realization China and meet the various actual requirements of fire-fighting and rescue provide satisfactory hommization package solution, the correctness of this programme and feasibility repetition test are fully proved.
Summary of the invention and implementation method
The core technology of descending lifeline involved in the present invention is that at the uniform velocity self-con-tained unit and shoe plate brake apparatus combine together dexterously by centrifugal friction.You are among us and we are among you, realizes the target of general function harmony.
Centrifugal friction at the uniform velocity self-con-tained unit mainly forms 9 speed speed raising apparatus jointly by two meshed gears groups, is wherein 48 teeth with the gear wheel of integrated assembly-20 of rope sheave, and pinion-3 that are engaged with are 16 teeth; One-level pinion drives gear wheel-6 of the second level by universal driving shaft, this gear wheel is 48 teeth, and pinion-18 that are engaged with are 16 teeth; The piece guide rail that gets rid of that the back of the body is attached to brake rim rotates with identical speed with pinion-18, get rid of piece in High Rotation Speed, order about along guide rail and outwards slide by centrifugal force, and produce friction with relatively static and case lid-2 that axis is identical drum type inwall, form reciprocal moment of friction.In friction radius (being the radius of garden, case lid-2 barrel shape inwall) with get rid of piece weight and after friction paster material (coefficient of friction) etc. determines, the size of moment of friction to get rid of square being directly proportional of piece rotational angular velocity.Speed is higher, and moment of friction is just larger, by the transmission of gear, realizes dynamic equilibrium rapidly with the heavy burden of the steel wire rope direct bearing of rope sheave, and the mode of this automatic feedback and response just, can ideally realize the object of landing at the uniform velocity.And velocity magnitude at the uniform velocity depends primarily on heavy burden in decline process, bear a heavy burden larger, velocity amplitude is at the uniform velocity also just higher.All clearly show by theory analysis and test, rationally controlling the most effective technical measures of decrease speed is gear ratio of adjusting speed change gear.Consider that GB requires heavy burden scope at 35 kilograms to 100 kilograms (and considering to leave enough redundancies), and decrease speed is less demanding in 1.5 meter per seconds, it is rational that gear ratio is set 9 times by the descending lifeline design the present invention relates to.This measure, will meet under the prerequisite of national standard requirement, for other correlated parts parameter designing provide enough adjustment spaces reliably stablizing.
Because the present invention is not high to the technical requirement of gear, it is just passable that gear material is elected No. 45 common steel as, depend primarily on the factors such as overall dimensions size and the strength of gear teeth as for the modulus of gear series, can in standard module series, between 1.0-2.0mm, choose.After the parameters such as gear ratio, rope sheave, brake rim radius and case lid-2 drum type inwall radius are determined, the size of shoe plate and weight will be the parameter that the design modifying free degree is higher, because frictional force is directly proportional to the quality (weight) of getting rid of piece; And the brake block that the friction plate that gets rid of piece can adopt the metallic fiber that motorcycle industry is conventional (also may contain other fibers) to make, the indexs such as its durability and temperature characterisitic all can meet the demands.
The shoe plate brake apparatus (seeing Fig. 2,3) of the descending lifeline the present invention relates to, mainly regulate variable bit spring-1 and spring adjusting button-2 etc. to form by brake shoes assembly-16 (Fig. 1), brake camshaft-2, brake lever-3, fixed handle-4, handle gripping strength, and brake shoes assembly-16 are arranged on pinion, get rid of piece, get rid of in the brake rim of the rigid attachment such as piece guide rail.Do not carrying out under brake condition, shoe plate separates with brake rim inwall, when spring or people that brake handle passes through are applied under the active force effect of brake lever, the outside spreading of cam two-way push shoe plate, produces frictional damping once touch the brake rim inwall rotating.After shoe plate material (coefficient of friction) is determined, the size of its frictional damping just depends on handle spring or the brake force manually applying.Due to the arm of force relation of brake lever, grip is exaggerated, so as long as apply less grip, be just enough to braking and even stop and stop rope sheave.After the grip that brake lever applies discharges, under the effect of brake shoes assembly back-moving spring-3, shoe plate recovers releasing orientation originally, and now, thing that descending lifeline bears a heavy burden continues to keep gliding with even safe speed.
In order to reduce different difference of bearing a heavy burden in corresponding at the uniform velocity speed, the shoe plate brake apparatus of the descending lifeline the present invention relates to, be provided with spring and pull the position adjusting mechanism of the arm of force at brake handle, conventionally initial normality is set on the shorter position of the arm of force, the design of spring parameter according to be can balance the heavy burden of 25 kilograms of rope sheaves, exceed 25 kilograms once bear a heavy burden, rope sheave just can start to rotate (heavy burden thing starts downward landing) by bearing a heavy burden drive, the initial damping value of Here it is shoe plate brake apparatus, this alleviates the at the uniform velocity pay(useful) load of self-con-tained unit of centrifugal friction in use to descending lifeline, the difference that reduces different heavy burden corresponding speeds plays a positive role.
As Fig. 2 shows, the brake shoes assembly of the shoe plate brake apparatus of the descending lifeline the present invention relates to, comprise that shoe plate (connecting friction plate), cam, camshaft, return spring etc. all adopt the standard fitting of motorcycle, have positive meaning to improving from now on the standardization of product design and production.
The descending lifeline the present invention relates to is not changing under the prerequisite of internal structure of product completely, only change the turnover mode of its suspending way and steel wire rope, just can, according to the on-the-spot requirement using, make product be set as two-way reciprocation type or two kinds of different specifications of unidirectional down-sliding type.
As shown in Figure 4, while use as " two-way reciprocating manner ", descending lifeline ear stud-11 (Fig. 1) firmly hung on the suitable position of rescue site, the steel wire rope of descending lifeline is respectively by being arranged on two steel wire rope conduit turnover of case lid below, steel wire rope is left to underground with one end of life line hook, the other end with worn life belt by rescue personnel and be connected, face thereby enter the state of falling; Responsible rescue personnel holds brake lever, can, under rescue personnel's assistance, be stepped out building by rescue personnel, and in state unsettled and that preparation declines, rescue personnel needs only take-off the brake handle, can be realized at the uniform velocity safety decline by rescue personnel.
Unidirectional down-sliding type in use, hang on suitable and reliable position by hook by steel wire rope upper end, and the other end leaves earthward.Hangers hole-6 (Fig. 4) clasp joint of the safety belt of being worn by rescue personnel and housing below.Because unidirectional down-sliding type is contrary with two-way reciprocation type at the action direction of brake lever secondary spring, brake lever is not in the time applying artificial grip completely, device, in braking state, just can be departed from building hovering in the air by rescue personnel, by rescue personnel's hovering steadily; In the time being held brake handle by rescue personnel, shoe plate unclamps on the contrary, and descending lifeline relies at the uniform velocity self-con-tained unit and uniform descent of centrifugal friction, as long as loosened brake lever by rescue personnel, and shoe plate spreading, speed just slows down at once.This is for common being saved oneself and just seemed hommization more by rescue personnel.
The descending lifeline the present invention relates to is also for being provided the possibility of soft landing by rescue personnel or goods.Such as two-way reciprocating manner, because each descending lifeline rope capacity should be determined according to the height of user's building of living in is corresponding, in the time that its life line hook of the steel wire rope leaving is back to approaching rescue layer (if subsidiary tool for mounting is better for the small establishments effect of sound, light warning function on life line or life vest), rescue personnel just can carry out brake operation in time, can make to be realized soft landing stably by rescue personnel or goods.For the unidirectional glide mode of following of descending lifeline, to pull off a soft landing and just need to increase some extra designs, this does not just list content of the present invention in.
As the descending lifeline of amateur common people oneself relief, except require simple and easy to use, due to phychology fragility, the function of well and reliably hovering to stable be important by rescue personnel's mood; In addition, the speed of decline should be stablized, and general speed should be relatively lower, and the shoe plate arrestment mechanism that the present invention relates to descending lifeline provides for meeting the demand of this personalization the possibility realizing.
Rescue in batches the descending lifeline of police equipment as specialty, except emphasis is considered security, also should embody the high efficiency of rescue, rescuer is according to on-the-spot actual needs, and reference is by rescue personnel's body weight, health and psychological quality etc., can pass through the adjustment to descending lifeline brake handle spring action position involved in the present invention, and meet targetedly the needs of different situations.
Once meet accident in being declined on the way by rescue personnel, descending lifeline as police specialist equipment also should possess the function that relief is provided in time, the descending lifeline the present invention relates to, when salvor declines arrival rescue scene by the unidirectional down-sliding type descending lifeline of another one, because it has empty-handed hovering function, just can vacate both hands and implement relief.
The outstanding advantage of descending lifeline another one the present invention relates to is that frame for movement is firm, substantially needn't maintain frequently and safeguard, the material source that design is used be abundant, and processing technology is simple, compared with the descending lifeline circulating with existing market, the descending lifeline the present invention relates to has obvious cost advantage.
