Abstract
The invention relates to a speed difference controller with a free contraction function. One end of an internal coil spring is fixed to a shell of the speed difference controller, and the other end of the internal coil spring is connected with a rotating shaft of a core. During normal use, a fall protection safety rope is pulled out, and the coil spring is contracted; after loads are released, a rope winding wheel is driven by the rotating shaft so as to wind the safety rope under the action of elasticity of the coil spring, so that the free contraction function is realized. The speed difference controller further has a speed difference locking function. In the condition of fall due to slipping, the fall protection safety rope is quickly pulled out, so that the rotating shaft and a rotating mechanism are driven to quickly rotate by the rope winding wheel, and under the action of centrifugal force, a pawl overcomes the tension of a tension spring so as to be opened and then is locked and jammed with a wheel disc, so that the speed difference locking function is realized. The speed difference controller further has an anti-impact function. When the pawl is opened and locked after fall due to slipping, the rotating mechanism rotates relative to the rotating shaft under the action of axial force of a friction plate, so that buffer force is provided for a falling person, death caused by excessive pulling force after locking is prevented, and the anti-impact effect is achieved.

Present invention is primarily targeted at providing a kind of safety means preventing accidental falling for personal height operation, with solve existing engineering construction, electric power, ship, communication, the field such as bridge accidental falling cause casualties, article damage, the problems such as under inefficiency.
To achieve these goals, the invention provides a kind of safety means preventing accidental falling for work high above the ground, including：Speed difference device housing；Rotating mechanism, is arranged on speed difference device enclosure interior by axle；Disc spring, by shaft compression rotating mechanism.
Further, arrest devices also include wind spring, and wherein, wind spring inner ring is fixing on the rotary shaft, and outer ring is fixed on speed difference device enclosure interior.
Further, rotating mechanism also includes ratchet and wheel piece, and ratchet is fixed on rotation steel plate by extension spring, and wheel piece is arranged in speed difference device housing.
Further, arrest devices also include rope-winding wheel, and rope-winding wheel is fixed in speed difference device housing by rotary shaft.
Further, rope-winding wheel also includes and drop protection safety rope, ball, spring and suspension hook, and wherein, ball, spring are arranged on drop protection safety rope, and suspension hook is fixed on safety rope one end.
Further, arrest devices also include shackle, and wherein, shackle is fixed on speed difference device housing.
Speed difference device of the present invention, speed difference device housing is fixed in internal wind spring one end, the other end is connected with core rotary shaft, during normal use, drop protection safety rope is drawn out, and wind spring shrinks, after load releases, in the presence of wind spring elastic force, rotary shaft drives rope-winding wheel to reclaim safety rope, completes free shrink function；In the case of slipping and falling, drop protection safety rope is quickly pulled out, and then rope-winding wheel is rotated axle, rotating mechanism accelerates to rotate, and under the action of the centrifugal force, ratchet is opened after overcoming tension spring tension, stuck with wheel disc locking, realizes speed difference latch functions；Meanwhile, rotating mechanism, under the responsive to axial force of friction plate, is relatively rotated with rotary shaft, to one cushion effect of personnel that falls, excessive the caused injures and deaths of the involve power after preventing by locking.
In addition to the object defined above, feature and advantage, the present invention also has other objects, features and advantages, and below with reference to figure, the present invention is further detailed explanation.
