Abstract
The utility model discloses a liquid controlled high-altitude life-saving device, comprising a rope, a reel and a winding rope handle, characterized in that the liquid controlled high-altitude life-saving device also comprises an oil pump and a speed limiting device; the rope is wound on the reel; the winding rope handle is at one end of the reel; the other end of the reel is connected with the oil pump through a one-way ratchet wheel; the oil output of the oil pump is connected with the speed limiting device in series; the utility model makes use of the weight of the human body to generate turning moment through the reel; the turning moment drives the oil pump to turn; the oil output of the oil pump is controlled by the speed limiting device; substantially the turning speed of the reel is controlled by controlling the oil output of the oil pump, therefore to reach the purpose that the escape personnel fall down safely.
Description
Technical field
The utility model relates to a kind of lifesaving appliance, and more particularly the utility model relates to a kind of pilot-operated type high-altitude life-saving appliance.Belong to high-altitude relief equipment technical field.
Background technology
According to the knowledge of the applicant, the present domestic utility model patent that a kind of high altitude rescue and operation slow descending device are arranged, its technical essential is main hoist cable one end to be tied up to building fall on the robust member at people place; The other end vertically lands face, and the descender takes and handles slow descending device and glides along main hoist cable.Main hoist cable can be with one or two, also can be with many.Slow descending device mainly is made up of several parts: substrate, be contained in pulley speed reducing mechanism, the bar arrestment mechanism on the substrate and take advantage of mounted mechanism.But this used complex structure of utility model, cost is higher, is not suitable for promoting the use of.
Summary of the invention
The high-altitude life-saving appliance that the purpose of this utility model is to provide a kind of suitable multiple crowd of simple in structure, in light weight, easy to operate, safe and reliable liquid-control speed-limiting to use.
The utility model is to take following technical scheme to realize:
A kind of pilot-operated type high-altitude life-saving appliance comprises rope, reel and wiring handle, it is characterized in that it also comprises oil pump and limiter of speed, and described rope is on reel, and the wiring handle is at an end of reel; The other end of reel connects oil pump by single direction ratchet, and the fuel-displaced and limiter of speed of oil pump is connected in series.
The utility model can also further be realized by following technical scheme:
Aforesaid a kind of pilot-operated type high-altitude life-saving appliance is characterized in that described limiter of speed is a hydraulic damper.
The utility model at type of service is: a kind of is that U type frame is inserted in (reel outwardly) on the window bottom transverse frame; Another kind is with the other end of stationary rope and the indoor object (as tables and chairs, running water pipe, steam heating pipe etc.) of bearing people's weight bolt mutually, makes device be in window underframe outer rim.After device was fixing, with one to two circle and buckle safety fastener on the waist spaced winding of the rope on the reel, the people climbed out of outside window and can escape.To escape as indoor somebody, behind the first arrival ground or safety area, can rope be rewound on the reel, so successively escape by the wiring handle.
The utility model utilizes human weight to produce turning moment by reel, this moment drives the oil pump rotation, the oil pump capacity of pump is subjected to the control of limiter of speed, is exactly in fact to control the rotary speed of reel by control oil pump oil pump capacity, thereby reaches the purpose that escape personnel's safety descends.
The utility model compared with prior art has following advantage:
1, controls people's decrease speed by the limiter of speed (claiming hydraulic damper again) that adopts the hydraulic throttle technology to make, this speed limit principle has guaranteed greatly that in decline process safe and reliability it and mechanical type, people are controlled the formula speed limit and can not be compared.The flow area size of limiter of speed is to determine for the people who satisfies different weight can escape safely and reliably, does not need artificial adjusting during use.
2, this apparatus structure is simple, volume is little, in light weight, easy to operate, safe and reliable, be fit to multiple crowd (as family, dormitory, hotel etc.) escape and use.
3, device is provided with the rope rewind mechanism, in the time allowed band, many people is escaped with life and limb successively.
4, this device core component is difficult for corrosion, and because of speed limiting system is the fluid pressure type closed circuit, fluid is difficult for leaking, and has the lubricating and antirust function, rope is the high-intensity fine steel cable, is difficult for getting rusty and goes rotten going bad, and therefore maintenance and security reliability proof cycle are long blanking time.
This device as long as limiter of speed is changed a little, can artificially be controlled opening and closing of speed limit oil circuit by special-purpose rope except being used for high-rise life saving, realize the descending motion of batch (-type) human body easily, and its purposes has:
1, high building external wall and windowpane clean and maintenance engineering.
2, the content production of large board and maintenance.
3, fire control and disaster rescue and equip with arms anti-riot personnel and handle accident.

The specific embodiment
Embodiment 1
A kind of as shown in Figure 1 pilot-operated type high-altitude life-saving appliance, wherein wiring handle (1), reel (2), rope (3), oil pump (4) and limiter of speed (5); Rope (3) is on reel (2), reel (2) makes rope (3) on reel (2) by the rotation of wiring handle (1), because reel (2) adopts single direction ratchet to be connected with oil pump (4), oil pump during wiring (4) can not rotate, have only when the people escapes, people's weight makes oil pump (4) rotation and pump oil by rope (3) and reel (2), and the velocity magnitude (being the speed speed that the people descends) of pump rotation is to control oily flow by limiter of speed (5) to decide.
Except that above embodiment, all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
Claims (2)
1, a kind of pilot-operated type high-altitude life-saving appliance comprises rope, reel and wiring handle, it is characterized in that it also comprises oil pump and limiter of speed, and described rope is on reel, and the wiring handle is at an end of reel; The other end of reel connects oil pump by single direction ratchet, and the fuel-displaced and limiter of speed of oil pump is connected in series.
2, a kind of pilot-operated type high-altitude life-saving appliance according to claim 1 is characterized in that described limiter of speed is a hydraulic damper.
