Abstract
A slow descent protector is used for a protection device enabling people or objects to descend from high altitudes at limited speed. The slow descent protector is mainly composed of a slow descent protector body, a hanging ring, a rotary wheel, a solid ball, an end cover, a slow descent rope and a bolt. The rotary wheel with the solid ball is arranged in a round hole of the slow descent protector body, and a plurality of arc grooves are formed in the round hole of the slow descent protector. The slow descent rope is wound on a rotary shaft of the rotary wheel, and one end of the slow descent rope is connected to people or the objects which must slowly descend. When the slow descent protector works, the slow descent rope drives the rotary wheel to rotate, the rotary wheel drives the solid ball to circumferentially move, the solid ball generates centrifugal force, the centrifugal force is increased along with the increase of the movement speed of the solid ball, and the rotary wheel can obtain reverse torque increased along with the increase of the speed. When the reverse torque is equal to the torque generated by the slowly-descending people or objects relative to the rotary wheel, the slowly-descending people or objects cannot be speeded up any more, and therefore the aim of slow descent at the limited speed is achieved.
Description
Technical field:
The present invention relates to a kind of device that people or object are declined by eminence speed limit.As the high-rise slow descent escape device of security against fire, safety guard of rock climbing etc. in sports.
Background technology:
The existing device that people or object are declined by eminence speed limit, the technology adopting is varied, but all has complex structure, and manufacturing cost is high, uses inconvenience or the poor defect of security reliability.
Summary of the invention:
Technical problem to be solved by this invention is: provide a kind of slow protector that falls for the deficiencies in the prior art.
The technical solution adopted in the present invention is: the slow protector that falls is by slowly falling protector body, suspension ring, swiveling wheel, medicine ball, end cap, slowly falling rope and bolt forms.Delay and fall becket bridle in the rotating shaft of swiveling wheel, slow one end that falls rope connects people or the object that must slow fall by jockey.Jockey can be hook or hook base etc.Several circular holes are radially evenly set on the circumference of swiveling wheel, 1 to 3 medicine ball is set in each hole.Swiveling wheel is arranged on slow falling in the circular hole of protector body, and several arc grooves are radially evenly set on the circumference of this circular hole.When the slow like this people who falls or object decline, the slow moving swiveling wheel of rope band that falls rotates, swiveling wheel drives medicine ball to circle as the center of circle taking swiveling wheel axis, in same circular hole, produce centrifugal force apart from the near medicine ball of swiveling wheel central axis, promote adjacent medicine ball and make its centrifugal force larger.Medicine ball produces centrifugal force N, makes medicine ball and the slow interior wall friction that falls protector body circular hole form frictional resistance F.When medicine ball moves to slow falling in the arc groove of protector body, medicine ball clashes into arc groove and makes groove surfaces produce reaction force P to medicine ball.Frictional resistance F and reaction force P all along with medicine ball centrifugal force N increase and increase.The size of centrifugal force N and the movement velocity of medicine ball square of medicine ball are directly proportional.Frictional resistance F and reaction force P produce opposing torque to the rotation of swiveling wheel.Along with the slow people who falls or the increase of object decrease speed, opposing torque increases simultaneously, and in the time that opposing torque equates with the torque of the slow people who falls or object generation, the people of decline or object decrease speed are no longer accelerated, and delay the object of falling with speed limit thereby reach.
The slow medicine ball that falls protector is rotatable and to move axially be the diameter that the Circularhole diameter of swiveling wheel is greater than medicine ball in the circular hole of swiveling wheel, and its degree of depth is greater than diameter of solid sphere sum in same circular hole.
The slow medicine ball radius that falls protector is less than the slow radius that falls protector body arc groove, otherwise medicine ball can not contact arc bottom portion of groove, groove is reduced to the decelerating effect of medicine ball.The slow degree of depth of falling protector body arc groove is less than the radius of medicine ball in addition, on the contrary medicine ball issue and be conigenous lock in the gentle effect of falling protector body arc groove of swiveling wheel, medicine ball can not rotate, and causes slowly to fall protector and can not work.
Due to the slow medicine ball arc groove reaction force P to medicine ball in the slow arc groove that falls protector body that falls protector; the opposing torque producing is greater than the opposing torque that medicine ball and descending lifeline protector body circular-hole internal-wall frictional force F produce; in the time that the quantity of arc groove equates with the circular hole quantity that medicine ball is installed; medicine ball littlely when large while causing opposing torque makes the slow protector that falls can not smooth working by arrive arc groove and leave groove simultaneously simultaneously, and so the arc groove quantity of falling protector body slow should be more than the circular hole quantity that medicine ball is installed.
Brief description of the drawings
Figure of description 1 and Fig. 2 are one embodiment of the invention structure cutaway views
Detailed description of the invention
Are one embodiment of the invention structure cutaway views referring to Figure of description 1 and accompanying drawing 2, this descending lifeline falls device mainly by slow falling protector body 1, suspension ring 2, swiveling wheel 3, medicine ball 4, end cap 5, slowly falling rope 6 and bolt 7 forms.The slow rope 6 that falls is looped around in the rotating shaft of swiveling wheel 3, and slow one end that falls rope 6 connects people or the object that must slow fall.7 circular holes are radially evenly set on the circumference of swiveling wheel 3,2 medicine balls 4 are set in each hole, swiveling wheel 3 is arranged on slow falling in the circular hole of protector body 1, and 8 arc grooves 8 are radially evenly set on the circumference of this circular hole.
