[0041] One end of the rotating shaft one 3, the rotating shaft two 9 and the two threaded shafts 10 is fixedly installed with two spring threes 32, one end of the plurality of spring threes 32 being abutted with the corresponding braking clamp 12, in order to prevent the plurality of spring threes 32 from being inclined outward under the action of centrifugal force, a resisting ring (not shown in the figure) is fixedly installed at one end of every two spring threes 32, the inner diameter of the resisting ring being greater than the diameter of the threaded shaft 10, ensuring that the resisting ring is always abutted with the corresponding braking clamp 12 under the elastic force of the spring three 32, always keeping the threaded ring 31 engaged with the threads on the threaded shaft 10 under the action of the plurality of spring threes 32 and the two spring twos 30, and the diameter of one end of the rotating shaft one 3, the rotating shaft two 9 and the two threaded shafts 10 being greater than the diameter of the sleeve hole, being able to prevent the braking clamp 12 from being separated from the threaded shaft 10.

[0042] When the elevator is pulled, the initial position of the braking clamp 12 is the farthest state, and it will not be in contact with the wire roller 1, ensuring the normal work of the wire roller 1.

[0043] When the torque transmitted by the buffer shaft 21 is overloaded (at this time, the elevator is overloaded, and the falling speed is accelerated), the axial separation of the gear ring two 18 overcomes the elastic force of the spring one 19, so that the gear ring two 18 is fully engaged with the gear ring one 17 (when the rotating speed is too high, the centrifugal force increases, so that the gear ring two 18 and the gear ring one 17 are subjected to greater centrifugal force, and when the torque returns to normal, the clutch is automatically separated (at a lower rotating speed, the centrifugal force is smaller, and the gear ring two 18 and the gear ring one 17 are still in the engaged state, so that the smooth power transmission is facilitated), so that the mechanism protection inside the machine during overload is realized.

[0044] When the overload occurs (the gear ring one 17 and the gear ring two 18 are fully engaged), at this time, the rotating shaft one 3 rotates and the rotating speed is large, under the action of the spring shaft, the two threaded shafts 10 rotate, the intermittent mutual approach of every two brake clamps 12 is realized, and then the brake clamps 12 intermittently brake the wire roller 1, so that the wire roller 1 is stably clamped, the setting of the spring two 30 can reduce the vibration during use, improve the stability during use, so that the brake clamps 12 and the wire roller 1 can be prevented from being directly locked, and the possibility of accidents is reduced.

[0045] The specific operation steps of the present application are as follows:

[0046] The motor 15 is started, the gear four 26 is driven to rotate through the connecting shaft 20, the gear three 25 is driven to rotate by the rotation of the gear four 26, the gear two 24 is driven to rotate through the transmission shaft 22 by the rotation of the gear three 25, the gear one 23 is driven to rotate by the rotation of the gear two 24, the buffer shaft 21 is driven to rotate by the rotation of the gear one 23, the first gear 27 is driven to rotate by the rotation of the buffer shaft 21, the second gear 29 is driven to rotate by the rotation of the first gear 27, and the wire roller 1 is driven to rotate by the rotation of the second gear 29 through the rotating rod 4, so as to lift the elevator.

[0047] When the elevator is overloaded (stall occurs during the descending process, and the rotating direction is opposite to that of the elevator), the wire roller 1 rotates rapidly, the buffer shaft 21 rotates rapidly, and the gear ring one 17 and the gear ring two 18 also rotate, at this time, the centrifugal force of the gear ring two 18 is greater than the elastic force of the spring one 19 due to the increase of the rotating speed, so that the gear ring one 17 and the gear ring two 18 are fully engaged, and then the rotating shaft one 3 is driven to rotate, so that the clamping force of the two brake clamps 12 on the wire roller 1 is flexibly changed during the high-speed rotation of the wire roller 1, the "if-then" braking effect is realized, the rotating speed of the wire roller 1 is slowly approached to the normal range through intermittent deceleration, the rotating speed of the wire roller 1 is gradually reduced by short-time resistance during each braking, and the internal structure of the equipment is prevented from being damaged due to excessive braking and sparks generated by high-speed friction under high temperature, so as to ensure the stability of the position of the elevator and realize the effective braking of the elevator.

[0048] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application.
