It is described according to above structure, the operation principle of counterweight charging assembly of the present invention is：The counterweight charging assembly is in work It needs to carry out free switching between counterweight load and zero load when making.When load condition, plastic steel that counterweight weight passes through 4mm Rope.As shown in Figures 2 to 4, by unloaded clamping device, handle 862 is pulled to the right more 60 degree, to middle seated position, similar water The flat-pushing principle for drawing elbow folder, mandril swing arm 822 drive mandril swing arm connecting rod 823, push the advance about 12mm of mandril 824, activity folder About 3mm is shortened in the gap held between block 830 and fixed clamp block 841, and toothed clamping face can clamp the plastic steel of 4mm at this time Rope.Swing arm at this time, swing arm connecting rod 823 and mandril 824 are on horizontal plane, and even into a line, elbow clamp mechanism reaches range, And it is in self-locking state, until reversion release handle manually.
The overturning grip block 842 of special designing can easily overturning be opened clockwise from clamped condition, if plastic steel Rope 850 encounters upward huge pulling force, and frictional force can drive overturning grip block 842 to be flipped up to relaxed state, be unlikely to Break cable wire.It can so realize anti-lock function when upward stress.The downward pulling force of cable wire essentially from Weight gravity, It is foreseeable size, is not necessarily to anti-lock function.When unidirectional clamping, cable wire pulls down, and the locking of circular arc wedge can not loosen；Steel Rope pulls up, and clamping jaw can be opened easily.
The clamping face of overturning grip block 842 is two semicircles cooperation of cam mechanism and movable grip block 830, by softness Cable wire is extruded in centre, small big under effective radius since the section of flipping block is similar to cam face, the gravity of counterweight itself to Under, it is only possible to that clamping device is enabled more to lock, can not loosen, realize and be held in place rear locking function.Meanwhile overturning grip block Shaft is supported by two compressed springs, can translate most 3mm to the right in the horizontal direction, the top power of mandril is excessive, or in steel When the downward pulling force of Suo Shoudong, play the role of adjusting buffering.In this way, unidirectional clamping function can be realized, cable wire is avoided to be pressed from both sides When being unable to stir any more after holding, encounters upward pulling force and break cable wire.
The overturning grip block of cable wire clamp system is designed to eccentric arc surface, under stressing conditions, when being rotated up, and radius Become small, the clamping force of cable wire is reduced, can smooth unlocking function.Conversely, being in increasingly tighter self-locking state.
The rear end of overturning grip block is supported by two groups of compressed springs, it is ensured that crank mechanism is under dieback state, its energy Certain telescopic action is played, ensures the validity clamped.
The working sections of movable grip block are designed to that size two is arc-shaped, in certain oblique when rubber cable wire can be allowed to clamp Degree improves frictional force.
In conclusion counterweight charging assembly of the present invention can make counterweight be in load or zero load at any time by retaining mechanism handle State, proper application scenario are vertical hangings in generating certain load torque on annulus, cam ring or cantilever.This hair It is bright that there is load and unloaded handoff functionality, it is method quick lock in and release counterweight weight by clamping.In the unloaded shape of clamping It when state, can ensure that counterweight will not be fallen because of gravity, while being moved upwards again without limitation on it, effectively improve mechanism safety Property.
