Refering to Fig. 4, when outer locking mechanism 1 is relatively rotated with internal locking mechanism 2, outer locking voussoir 1-2 and internal locking voussoir
Two kinds of working conditions are realized in 2-2 cooperations：
Internal locking mechanism 2 axially movable, and then realizes the axial compression of elastic element 3 and friction pair 4,
The axial position of internal locking mechanism 2 is constant, and torque is mutually transferred between outer retaining mechanism 1 and internal locking mechanism 2.
Refering to Fig. 2, Fig. 3, outer locking voussoir 1-2 includes the first outer outer working face 1-2-2 of working face 1-2-1 and second, the

During braking operation, clockwise torque is passed to outer locking mechanism 1, outer locking by the gravity of weight by transmission system
Mechanism 1 rotates clockwise, and the first outer working face 1-2-1 and the first inner working face 2-2-1 contact squeezes force internal locking mechanism 2
Axial movement is generated, compresses elastic element 3, pressing friction pair 4, and the unilateral bearing of installation stops clockwise in outer shroud 5 at this time
Turning, outer shroud 5 cannot rotate clockwise, therefore the pair 4 that rubs limits movement by outer shroud 5, and internal locking mechanism 2 rotates clockwise, from
And the moment of friction rotated clockwise is generated to friction pair 4, arrestment mechanism rotation stop under the action of moment of friction realizes weight
Reliable automatic braking.Energy expenditure during friction pair 4 declines weight in braking process, reduces the impact to mechanism.

Contact squeeze, internal locking mechanism 2 do not generate axial movement.Friction pair 4 compresses under the initial pressure of elastic element 3.Internal locking
Mechanism 2 rotates clockwise, so as to generate the moment of friction rotated clockwise to friction pair 4；And it is installed at this time in outer shroud 5 unidirectional
Bearing rotation stop clockwise, outer shroud 5 cannot rotate clockwise, therefore the pair 4 that rubs limits movement, arrestment mechanism need gram by outer shroud 5
Initial friction torque is taken, has internal locking mechanism 2 to be directly passed to outer locking mechanism 1 torque, realizes the work(of normal decentralization weight
Energy.When weight accelerates to transfer, mechanism can be automatically into on-position, and passes through during friction pair 4 declines weight and generate
Portion of energy consumption, be then again introduced into the decentralization weight stage, such cycle operation to ensure the steady decentralization of weight, subtracts
Few impact to mechanism.The adjusting of initial friction torque can be achieved in the initial compression amount of regulation elasticity element 3.
During heavy lift, internal locking mechanism 2 rotates counterclockwise, the first outer working face 1-2-1 and the first inner working face 2-2-1
Contact squeeze forces internal locking mechanism 2 to generate axial movement, compresses elastic element 3, and pressing friction pair 4.It is at this point, unidirectional
It axially rotates counterclockwise, internal locking mechanism 2 rotates counterclockwise together with the rotation counterclockwise of dynamic friction pair 4, friction pair 4 with outer shroud 5.
Outer locking mechanism 1 rotates counterclockwise under the drive of interior retaining mechanism 2, realizes the function of normal hoisting weight.
