Description
Technical field the invention belongs to delay from high-altitude building or structures falls and a kind of rope landing-gear of height rescue, work high above the ground, refers to a kind of self-controlled slow falling device especially.
The background technology high-altitude slow-descending equipment has polytype and structure, and personnel are by the transfer of high-altitude to the low latitude for the realization of the equal energy of its function.Wherein typical rope falls the class patent and relies on the own wt of human body as the power that descends in the principle design, utilize personnel descend in device rope-winding wheel rotation speedup, the centrifugal brake block that is connected with the rope-winding wheel consubstantiality moves outward with the fixed friction piece and produces damping force, and the effect that reaches dynamic equilibrium makes the people drop to safety place with a speed that at the uniform velocity descends relatively.As China patent CN86207152 " high-altitude self-controlled safe life-saving descending lifeline ", decrease speed is less than 2 meters of per seconds, but and the high-altitude unsettled braking brake of fixing a point carry out work; China patent CN2175011 " high building lifesaving slow falling apparatus ", average reduction of speed is about 0.15 meter of per second; China patent CN2193753 " fire in high buildings lifesaving descent control device ", it is zero that centrifugal brake shoe and brake drum generation frictional force make the decline acceleration, rope ends is installed safety belt simultaneously, can be used alternatingly continuously.The obvious weak point of said apparatus is can not realize effective control of decrease speed and steadily hover that can't eliminate personnel's feared state of mind, the influence that the scope of promoting the use of is subjected to crowd characteristic is big.
Summary of the invention the object of the present invention is to provide a kind ofly can realize that personnel are from the main control decrease speed, and the realization personnel are skyborne steadily hovers, eliminate user's the feared state of mind, optimize structure simultaneously, weight reduction, improve reliability, enlarge the high-altitude self-controlled slow falling device that is suitable for crowd's scope.
For achieving the above object, the technical scheme that the present invention takes is: a kind of high-altitude self-controlled slow falling device, comprise housing, friction rope sheave and the slow rope that falls, it is characterized in that described friction rope sheave is divided into upper and lower two groups, be symmetricly set on the upper and lower of ACTIVE CONTROL gear shaft and by gear and its engagement, the friction bands wheel shaft is fixed in the co-axial grooves that is made of two side bodies, and rolling bearing is enclosed within on the friction bands wheel shaft, and the friction rope sheave is enclosed within on the rolling bearing; Be provided with between upper and lower friction rope sheave and two side bodies and be subjected to the disc type friction plate that dish spring precompose is exerted oneself; The ACTIVE CONTROL gear shaft is positioned at the geometric center of housing, its external part is supported on the side body and with the handle of hull outside and links to each other, another axle head is supported on the spiral sleeve, spiral sleeve is fixedly mounted on the opposite side housing and is on the same axis with the ACTIVE CONTROL gear shaft, ACTIVE CONTROL gear shaft both sides are equipped with friction plate respectively, helical axis is connected with the spiral sleeve other end by transmitting screw thread, its front end acts on the friction plate of ACTIVE CONTROL gear shaft both sides by thrust bearing and disk spring, adjust knob and be connected, adjust knob by rotation and can adjust the active force that acts on ACTIVE CONTROL gear shaft both sides with the spiral the tip of the axis; The slow rope that falls is wrapped in the conductor rope groove of upper and lower two friction rope sheaves, slowly falls rope and is provided with the damping dead turn at the import and export of housing, adjusts its damping force by tight power swing handle up and down; High-strength suspension becket bridle is fixed on the corresponding site of device, and human body is hung on device by high-strength suspension becket bridle.
Compared with prior art, the present invention has following characteristics:
1. human body weight acts on friction decline turning moment that produces on the rope sheave and the reverse frictional couple square that the disc type friction plate acts on the rope sheave that rubs and reaches static balancing, the power resources that descend are manually rotated the handle that links to each other with the ACTIVE CONTROL gear shaft in operating personnel, and the rope sheave that rubs up and down of drive synchronously rotates according to equidirectional, realize that operating personnel are in company with the slow decline of falling the rope safety and steady in slow descending device edge, and can not have at any time to impact and hover, eliminate user's the feared state of mind.
2. the body weight load change scope that adapts to operating personnel is wide, and body weight the personnel in 30-120 kgf scope all can safe and reliablely use.
3. because device is to descend along the slow rope that falls, be not subjected to the restriction of falling head, the working depth scope is wide.
4. decrease speed by operating personnel from main control, decrease speed per second 0-0.5 rice, flexibly automatic control, security performance is higher, has reduced the influence of other hazard factor in the decline passway.
5. the adaptation population is in extensive range, particularly has the healthy population that adjustable control means is adapted to various age brackets, also can use after one-armed man scholar's training.Because the friction rope sheave is symmetrical arranged up and down, only need to adjust the fixed position of high-strength suspension becket bridle, just can satisfy the selection requirement that the right-hand man is accustomed to the personage.
6. because the rope sheave of friction up and down, two side bodies of device are symmetrical structure, make its compactness reasonable in design.
