[0048] Example

[0049] A small-sized mounting and releasing mechanism for a lifting eye of a heavyweight hanging object of the first class comprises: a side plate 1, a hook 2, a hook shaft 3, a locking block 4, an anti-sway frame 5, an anti-sway screw 6, a gap retaining column 7, a lever 8, a lever 9, a release torsion spring 10, a locking torsion spring 11, a pull rope 12, a cable drum 13, a steering gear 14, and a mounting frame 15.

[0050] 1) The side plate 1 is the main structure of the mounting and launching device, used to connect the main parts of the mechanism, and has a waist-shaped hole 101 and a round hole 102.

[0051] 2) The waist-shaped hole 101 is used to maintain the vertical linear motion of the lever 9.

[0052] 3) The circular hole 102 is used to observe the locking relationship between the hook 2 and the locking block 4.

[0053] 4) There are multiple gap-maintaining columns 7, which are distributed at different positions of the mounting and launching device to maintain the gap between the two side plates 1 and ensure that the hook 2, the locking block 4, and the lever 8 can move smoothly. The thickness of the hook 2, the locking block 4, and the lever 8 is consistent, and the thickness of the maintaining column 7 is 0.2mm thicker than the above parts.

[0056] 7) One end of the lever 8 has a long hole for the lever 9 to move. When the lever 9 moves along the waist-shaped hole 101 of the side plate 1, it pushes the lever 8.

[0057] 8) One end of the release torsion spring 10 is connected to the side plate 1, and the other end is connected to the hook 2, and the torsion force forces the hook 2 to rotate in the direction of release.

[0060] Principle description:

[0061] Release process: The steering gear 14 is the mechanism for generating the original power of release. When the release action starts, the steering gear 14 drives the cable disc 13 to pull the pull rope 12 to contract. The pull rope 12 pulls the lever 9 upward. The lever 9 drives the lever 8. The lever 8 drives the locking block 4 fixed thereto. The locking block 4 rotates to complete the unlocking action. Figure 4 shown.

[0062] The locking block 4 rotates around its own axis, and the locking block 4 has a locking plane 401 and a vertical plane 402. When the locking plane 401 contacts the locking plane 202, the locking block 4 locks the hook 2. The locking block 4 rotates around its own axis until the locking plane 401 and the locking plane 202 are offset, and the locking fails, the hook starts to rotate, and the lifting lug 16 is released, and the dropping action is completed. Figure 5 shown.

[0063] Waiting-for-mounting state: After the hook 2 releases the lifting lug 16, the hook 2 remains in the released state under the action of the release torsion spring 10, and the locking plane 202 of the hook 2 contacts the gap-keeping column 7. The servo 14 is restored to the state before the release, the pull rope 12 relaxes and stretches, and the locking block 4 rotates in the locking direction under the action of the locking spring 11, so that the vertical plane 402 contacts the arc surface 201, and the vertical plane 402 of the locking block 4 contacts the arc surface 201 of the hook 2, even if the pressure of the vertical plane 402 on the arc surface 201 exceeds the axis of the hook shaft 3. The mounting and releasing device remains in the waiting-for-mounting state, and the locking block 4 remains in the waiting-for-locking state, such as Figure 6 shown.

[0064] Mounting process: Use the lifting lug 16 to push the locking push surface 203 of the hook 2, and the hook 2 rotates around the hook axis 3 ( Figure 7 The arc surface 201 of the hook 2 and the vertical plane 402 of the locking block 4 contact and move relative to each other until they are offset from each other. The locking block 4 rotates under the drive of the locking spring 11, so that the locking plane 401 of the locking block 4 contacts the locking plane 202 of the hook, completing the locking.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
