Abstract
The task of the invention is providing a simple structure, small size, light weight, easy operation, and easy carrying high altitude landing devices. The ropes uses whole armored rope without nylon layer, adjust speed brake device, receive rope device, and they are designed into one unit. It has characteristics of uniform and adjustable decline rate, brake hovering in half-way, it can be used repeatedly, and the use height is unrestricted, it is the best tool of escape personnel in high buildings emergency escape rapidly. When fire or accident happen, the personnel in danger can escape themselves immediately, the use is wider in defense, military, industrial and agricultural production, climbers, explorer, and can be used for airborne troops and supplies landed at low altitude, the firemen wrecking, the rescue personnel escaping.
Description
The present invention is a kind of simple in structure, and volume is little, and is in light weight, easy to operate, and portable high-altitude landing-gear relates to the skyscraper dangerous situation and saves oneself, and he rescues, fire-fighting, and work high above the ground, mountain-climbing is explored, lifting goods, military field such as airborne.
Chinese patent disclosed ' lifesaving descent control device ' and existing technology; mostly adopt by unify friction eceleration system and rope dish structure of pinion unit and form; it is steel wire outsourcing polyamide fibre braid that rope adopts core; it need rotate drive by rope and the friction of drive V-shaped groove under human body gravity; driven gear transmission system and friction deceleration system are controlled falling speed; such drive mechanism is complicated, poor reliability, and volume is big; because the polyamide fibre layer and the steel wire percentage elongation of rope are different; bearing a heavy burden mainly concentrates on the steel wire rope, and the polyamide fibre layer mainly plays frictional drive effect and protective effect, as the steel wire rope defectiveness; be difficult for finding from the outside; polyamide fibre layer stress deformation is big, inflammable in addition, and be easily aging; service life is short; for the needs of frictional drive, this special wirerope diameter is thicker, in skyscraper uses; the increase of rope capacity; the volume and weight of rope is bigger, and is not portable, uses inconvenient.
The objective of the invention is to remedy the prior art deficiency, provide a kind of simple in structure, volume is little, in light weight, easy to use, and portable high-altitude landing-gear, from principle, cancelled ' lifesaving descent control device ' and existing technology on the structure and adopted by the pinion unit friction eceleration system that unifies, and rope to adopt core be the labyrinth of steel wire outsourcing polyamide fibre braid, adopt a kind of friction eceleration principle of novelty, rope adopts naked steel wire rope, structure is simplified greatly, the very wide model of volume-diminished, range of application.
The technical solution used in the present invention is; A kind of portable downfall equipment, rope adopts the full steel wire rope that does not have the polyamide fibre layer, the speed governing arrestment mechanism, the rope drawing machine structure is designed to one.Have support 1, friction plate 2, pressing plate 3, straight pin 4, adjusting handle 5, braked wheel 6, safety door hook 7, steel wire rope 8, pull bar 9, brake axle 10, transposition handle 11, a left side, right two end cap 12, safety belt 13 is formed.It is characterized by; Brake axle has step through-hole vertically, and an end face is a screwed hole, radially has the key-way shape through hole, the other end has square groove, and axle outer surface both ends are cylindrical, and the middle part is conical, braked wheel is the belt wheel shape, axially have conical bore, match with the brake axle taper seat, cylindrical outer surface has square groove, steel wire rope one end is fixing in groove, be looped around on the interior axle of groove, the stiff end of steel wire rope is provided with safety door hook, so that be connected and fixed fast with the fixed bearing thing.Friction plate, pressing plate are annular, are connected with the pull bar of braking in the axis hole by straight pin, rotate screw on adjusting handle or the pull bar with pressing plate, friction plate, and braked wheel compresses on brake axle.Support is a U-shaped, and two ends have the hole, is enclosed within on the brake axle, and the lateral aperture below has the hole, and two end cap is from a brake axle left side, and the right side is assembled together.Adjusting handle one end is a disc, the other end is cylindrical, have screw thread, cooperate with the screwed hole on the brake axle, rectangular cylindrical of transposition handle, an end radially have the hole and are stuck in the brake axle square groove by the alignment pin location, and the other end is stuck in the hole of support side, end face has screwed hole, is screwed.
Be described further below in conjunction with enforcement of the present invention and accompanying drawing;
Fig. 1 is an operation principle structure chart of the present invention
Location drawing when Fig. 2 receives rope for the present invention is positioned at
With reference to Fig. 1, downfall equipment is positioned at the speed governing application position, transposition handle one end is stuck in the brake axle square groove is located by alignment pin, one end is stuck in the hole of support side, be screwed, the stiff end of steel wire rope is fixing on support by safety door hook, safety belt is fixed on the support, when fastening one's safety belt, the people use downfall equipment when the high-altitude falls, under the gravity effect, pass through support, brake axle, braked wheel, steel wire rope, safety door hook acts on gravity on the fixed bearing thing, because the body weight for humans masterpiece is used in the axle center, wire line thimble is on brake axle, depart from the stressed position and the braked wheel axle center of steel wire rope, produce a turning moment, brake axle, braked wheel cooperates by taper seat, braked wheel is being subjected to human body gravity, pressing plate under the friction plate responsive to axial force, produces an equal and opposite in direction at brake axle conical surface and braked wheel female cone surface, the opposite frictional resistance moment of direction, friction plate and braked wheel end face also produce an equal and opposite in direction, and the frictional resistance moment that direction is opposite is in the landing process, regulate the down big of axial force, can control sinking speed, perhaps stop the size of frictional resistance moment midway, relevant with the tapering of brake axle taper seat and braked wheel internal conical surface, tapering is the 8-45 degree, chooses 12 degree for best, and the size of friction plate diameter also changes the size of frictional resistance moment.
The location drawing when receiving rope for downfall equipment is positioned at reference to Fig. 2, when unclamping hold-down screw transposition handle and in the hole of support side, screw out, the rolling transposition handle, brake axle can be at support, rotate freely in the shell aperture, under the effect of brake axle taper seat frictional force, drive the braked wheel rotation, wire line thimble on axle, has been realized receiving the rope function.
The rub size of moment of downfall equipment frictional resistance, regulate by rotation hand wheel, also can regulate by the screw on the braking axis hole draw-in bar, when rotation hand wheel unclamps, regulate initial frictional resistance moment of rubbing by the screw on the pull bar, when in case of emergency using down, only need fix safety door hook and just can use, can escape danger rapidly.
The present invention in use can realize saving oneself, and can realize that also he rescues, when mode is saved oneself in employing, safety door hook is fixing on the fixed bearing thing, and safety belt is fixed on the downfall equipment support, and the operator can regulate sinking speed arbitrarily, as run into child, old man, the wounded can adopt him to rescue mode, and the downfall equipment support is fixed on the fixed bearing thing, safety belt is fixed on the safety door hook, rotates adjusting handle by other people and can regulate sinking speed.To ground, also can use people and goods's safe falling or in parallel the use with the downfall equipment series connection as required.
