Abstract
The protector protection device for people or object being declined by eminence speed limit drops in a kind of delaying.Main dropped protector body, suspension ring, swiveling wheel, medicine ball, end cap, slow descending rope and bolt constituted by slow.The swiveling wheel being provided with medicine ball is arranged in the slow circular hole dropping protector body, and the slow circular hole dropping protector body is provided with several arc groove.Slow descending rope is looped around in the rotating shaft of swiveling wheel, and one end connects the people or object that must slow drop.Delaying slow descending rope when dropping protector work and wheel rotation is rotated, swiveling wheel drives medicine ball to circle, medicine ball generation centrifugal force, and centrifugal force increases with the speed that medicine ball moves and increases so that swiveling wheel obtains the opposing torque increased with speed increase.When opposing torque is equal with the torque that swiveling wheel is produced by the slow people dropped or object, the people of decline or object do not further accelerate thus reaching speed limit to delay the purpose dropped.
Description
Technical field:
The present invention relates to a kind of device people or object declined by eminence speed limit.Such as the high-rise slow descent escape device of security against fire, the safety guard etc. of rock climbing in sports.
Background technology:
The existing device that people or object are declined by eminence speed limit, the technology adopted is varied, but all there is structure complexity, and manufacturing cost is high, in-convenience in use or the defect of security reliability difference.
Summary of the invention:
The technical problem to be solved is: provides one to delay for the deficiencies in the prior art and drops protector.
The technical solution adopted in the present invention is: the slow protector that drops is dropped protector body, suspension ring, swiveling wheel, medicine ball, end cap, slow descending rope and bolt constituted by slow.Slow descending rope is looped around in the rotating shaft of swiveling wheel, and one end of slow descending rope connects the people or object that must slow drop by connecting device.Connecting device can be hook or hook base etc..Radially uniform on the circumference of swiveling wheel several circular hole is set, 1 to 3 medicine ball is set in each hole.Swiveling wheel is arranged in the slow circular hole dropping protector body, radially uniform on the circumference of this circular hole arranges several arc groove.When the so slow people dropped or object decline, slow descending rope is rotated wheel rotation, swiveling wheel drives medicine ball to circle with swiveling wheel axis for the center of circle, produce centrifugal force from the medicine ball that swiveling wheel central axis is near in same circular hole, promote neighboring solid ball to make its centrifugal force bigger.Medicine ball produces centrifugal force N so that medicine ball forms frictional resistance F with the slow interior wall friction dropping protector body circular hole.When medicine ball moves in the slow arc groove dropping protector body, medicine ball clashes into arc groove and makes groove surfaces that medicine ball is produced counteracting force P.Frictional resistance F and counteracting force P increases along with medicine ball centrifugal force N and increases.The size of centrifugal force N of medicine ball is directly proportional to the movement velocity square of medicine ball.The rotation of swiveling wheel is produced opposing torque by frictional resistance F and counteracting force P.Along with the increase of the slow people dropped or object decrease speed, opposing torque increases simultaneously, and when opposing torque is equal with the torque that the slow people dropped or object produce, people or the object decrease speed of decline do not further accelerate, thus reaching the slow purpose dropped with speed limit.
The slow medicine ball dropping protector is rotatable and move axially the Circularhole diameter diameter more than medicine ball of i.e. swiveling wheel in the circular hole of swiveling wheel, and its degree of depth is more than diameter of solid sphere sum in same circular hole.
Delay the medicine ball radius dropping protector less than the slow radius dropping protector body arc groove, otherwise medicine ball can not contact arc bottom portion of groove and the decelerating effect of medicine ball is reduced by groove.The additionally slow degree of depth radius less than medicine ball dropping protector body arc groove, on the contrary medicine ball issues be conigenous lock in the swiveling wheel effect dropping protector body arc groove of easing up, and medicine ball can not rotate, and causes and slow drop protector and can not work.
Due to the slow medicine ball arc groove counteracting force P to medicine ball in the slow arc groove dropping protector body dropping protector; produced opposing torque is more than opposing torque produced by medicine ball and descending lifeline protector body circular-hole internal-wall frictional force F; when the quantity of arc groove is equal with the circular hole quantity installing medicine ball; medicine ball by arrive simultaneously arc groove and leave simultaneously when groove causes opposing torque big time little make slow drop protector can not smooth working, so the slow arc number of recesses dropping protector body should more than the circular hole quantity installing medicine ball.
Accompanying drawing explanation
Figure of description 1 and Fig. 2 are one embodiment of the invention structure sectional views
Detailed description of the invention
Being one embodiment of the invention structure sectional view referring to Figure of description 1 and accompanying drawing 2, this descending lifeline drops device and is mainly dropped protector body 1, suspension ring 2, swiveling wheel 3, medicine ball 4, end cap 5, slow descending rope 6 and bolt 7 constituted by slow.Slow descending rope 6 is looped around in the rotating shaft of swiveling wheel 3, and one end of slow descending rope 6 connects the people or object that must slow drop.Radially uniform on the circumference of swiveling wheel 3 arranging 7 circular holes, arrange 2 medicine balls 4 in each hole, swiveling wheel 3 is arranged in the slow circular hole dropping protector body 1, radially uniform on the circumference of this circular hole arranges 8 arc grooves 8.
