The multiple self-locking devices are respectively located on one side of one set of notches. After the sling is placed in the notch and falls to the bottom of the notch, the self-locking device prevents the sling from moving out of the notch.

[0006] Furthermore, the self-locking device includes a latch and a lock cylinder. The lock cylinder is a regular or irregular C-shaped structure with its opening facing the notch. The lock cylinder is vertically disposed within the inner ring of the lifting beam and is rotatably connected to the inner ring sidewall of the lifting beam in a vertical plane. The latch is disposed on one side of the notch and is connected to one side of the inner ring surface of the lifting beam along its length direction. It is extended and retractable in a direction perpendicular to the inner ring side surface of the lifting beam. In the non-working state, the lower edge of the lock cylinder is higher than the lower end face of the notch, the upper edge of the lock cylinder is located above the latch, and the latch is in an extended state. In the working state, the lower edge of the lock cylinder is lower than the lower end face of the notch, the upper edge of the lock cylinder is located above the latch, and the lower end face of the latch abuts against the upper edge of the lock cylinder.

[0007] Furthermore, the upper surface of the latch includes an inclined surface that slopes downward from the side near its connection with the lifting beam, and in the non-working state, the upper edge of the lock cylinder is located above the inclined surface.

[0008] Furthermore, a groove is provided on the inner ring sidewall of the lifting beam located on one side of the notch, and the longitudinal section of the latch is a right trapezoid, with its vertical surface connected to the bottom surface of the groove; under the pressure of the lock cylinder, the latch moves into the groove, and when the lock cylinder rotates to the bottom of the groove, the latch pops out.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-3As shown, a self-locking turning beam includes a beam 1 and multiple self-locking devices. The beam 1 has a rectangular ring-shaped cross-section. Multiple sets of notches 11 extending downwards from their upper ends are formed on both side walls along the beam 1's length. The multiple self-locking devices are respectively located on one side of one set of notches 11. After a sling 4 is placed inside a notch 11 and falls to the bottom of the notch 11, the self-locking device prevents the sling 4 from moving out of the notch 11. Several lifting lugs 8 are mirror-symmetrically arranged on the upper surfaces of both arms along the beam 1's length, with the lower surfaces of the lugs 8 connected to the upper surfaces of the beam 1.

[0021] In this embodiment, the self-locking device includes a latch 3 and a lock cylinder 2. The lock cylinder 2 is a regular or irregular C-shaped structure with its opening facing the notch 11. The lock cylinder 2 is vertically disposed within the inner ring of the lifting beam 1 and is rotatably connected to the inner ring sidewall of the lifting beam 1 in a vertical plane. The latch 3 is disposed on one side of the notch 11 and is connected to one side of the inner ring surface of the lifting beam 1 along its length direction. It is extended and retracted in a direction perpendicular to the inner ring side surface of the lifting beam 1. In the non-working state, the lower edge of the lock cylinder 2 is higher than the lower end face of the notch 11, and the upper edge of the lock cylinder 2 is located above the latch 3. The latch 3 is in an extended state. In the working state, the lower edge of the lock cylinder 2 is lower than the lower end face of the notch 11, and the upper edge of the lock cylinder 2 is located above the latch 3. The lower end face of the latch 3 abuts against the upper edge of the lock cylinder 2.

[0022] Furthermore, the upper surface of the latch 3 includes an inclined surface that slopes downward from the side near its connection with the lifting beam 1. In the non-working state, the upper edge of the lock cylinder 2 is located above the inclined surface.

[0023] In some embodiments, a groove 12 is provided on the inner ring sidewall of the lifting beam 1 located on one side of the notch 11. The longitudinal section of the latch 3 is a right trapezoid, and its vertical surface is connected to the inner bottom surface of the groove 12 by a spring 6. The lock cylinder 2 is sickle-shaped, narrow at the top and wide at the bottom. The lock cylinder 2 is connected to the lifting beam 1 by bolts 5 and nuts passing through the two arms along the length direction of the lifting beam 1 and its own lower middle part. Under the downward pressure of the lock cylinder 2, the latch 3 moves into the groove 12. When the lock cylinder 2 rotates to below the groove 12, the latch 3 pops out.

[0024] To facilitate the movement of the latch 3 into the groove 12 when preparing to remove the lifting device, a pull member is connected to the end face of the latch 3 connected to the groove 12. A through hole is provided on the inner bottom surface of the groove 12, and one end of the pull member extends through the through hole to the outside of the lifting beam 1. In some embodiments, the pull member is a pull rope 7 or a pull rod.
