Description

Technical Field

[0001] The utility model relates to the technical field of mechanical connectors, in particular to a lifting ring body braking device and a rotating lifting ring using the same. Background Art

[0002] Rotating lifting rings are primarily used for hoisting wind turbine equipment and are installed on mold mounting holes for lifting and flipping. Most hoisting products on the market lack a braking function, allowing the ring to rotate flexibly during use. However, adding a braking function in some situations can improve the operability of the lifting ring and thus enhance operator safety. CN220664662U discloses a side-pull lifting ring, comprising a pull ring, a sleeve, and a bolt. The pull ring is fixed to the sleeve by a clamping ring and abuts against the clamping ring, creating frictional resistance between the pull ring and the clamping ring when rotating along the sleeve. The pull ring can be manually adjusted to rotate to the desired angle, thereby positioning the pull ring's rotation angle and preventing it from randomly flipping and colliding with the equipment or surrounding accessories. Although the pull ring has a braking function, the structure is relatively complicated to install and remove. Due to the frequent friction caused by the abutment between the pull ring and the clamping ring during use, it is not easy to replace and maintain. In addition, the setting position of the clamping ring is closely related to the size of the pull ring. If the error is too large, the pull ring will not be locked or the pull ring will not rotate during use. Utility Model Content

[0003] The purpose of the utility model is to provide a lifting ring body braking device and a rotating lifting ring using the same in order to solve the technical problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: a ring body braking device of a lifting ring, comprising a screw, a baffle, and a wave spring. The ring body of the lifting ring is fixed to the two ends of the ring body base of the lifting ring by the screw and rotates axially along the ring body base. The baffle is provided with a first through hole through which the screw passes, and the ring body is provided with a second through hole which is sleeved on both ends of the ring body base. The ring body base is provided with a first countersunk hole for fixing the screw. The screw passes through the baffle, the wave spring, and the second through hole in sequence and enters the ring body base and is fixed in the first countersunk hole of the ring body base.

[0005] The screw is a hexagon socket countersunk screw.

[0006] The first through hole gradually becomes larger at one end close to the screw, and the maximum diameter of the first through hole is larger than the diameter of the screw head, and the minimum diameter of the first through hole is larger than the diameter of the screw thread and smaller than the diameter of the screw head.

[0007] The ring body is provided with a second countersunk hole for placing the wave spring. The diameter of the second countersunk hole is larger than the diameter of the second through hole, and the axis of the second countersunk hole coincides with the axis of the second through hole.

[0008] Both ends of the ring base are provided with connecting ears, the second through hole is sleeved on the connecting ears, the first countersunk hole is arranged in the connecting ears, and the axes of the first countersunk holes in the two connecting ears coincide.

[0009] The screw is provided with an external thread, and the first countersunk hole is provided with an internal thread adapted to the screw.

[0020] The present invention will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-2 As shown, a ring-body braking device of a lifting ring includes a screw 1, a baffle 2, and a wave spring 3. The ring body 4 of the lifting ring is fixed to the two ends of the ring body base 5 of the lifting ring by the screw 1 and rotates axially along the ring body base 5. The baffle 2 is provided with a first through hole 21 through which the screw 1 passes. The ring body 4 is provided with a second through hole 41 which is sleeved on both ends of the ring body base 5. The ring body base 5 is provided with a first countersunk hole 51 for fixing the screw 1. The screw 1 passes through the baffle 2, the wave spring 3, and the second through hole 41 in sequence and then enters the ring body base 5 and is fixed in the first countersunk hole 51 of the ring body base 5.

[0022] Since there is a wave spring 3 at the side end of the ring body 4, when the ring body 4 rotates axially at both ends of the ring body base 5, the wave spring 3 interacts with the ring body 4 and the baffle 2 at both ends, so that the ring body 4 generates a certain resistance during rotation, and external force is required to rotate.

[0023] The screw 1 is a hexagon socket countersunk screw.

[0024] The first through hole 21 gradually widens at the end closest to the screw 1, and the maximum diameter of the first through hole 21 is larger than the diameter of the head of the screw 1, while the minimum diameter of the first through hole 21 is larger than the diameter of the thread of the screw 1 and smaller than the diameter of the head of the screw 1. This allows the head of the screw 1 to enter the baffle 2 after passing through it, preventing it from being scratched by the head of the screw 1 when the eye is operated.

[0025] The ring body 4 is provided with a second countersunk hole 42 for placing the wave spring 3 . The diameter of the second countersunk hole 42 is larger than the diameter of the second through hole 41 , and the axis of the second countersunk hole 42 coincides with the axis of the second through hole 41 .

[0026] Both ends of the ring base 5 are provided with connecting ears 52, and the second through hole 41 is sleeved on the connecting ears 52, so that the ring body 4 can rotate axially along the connecting ears 52. The first countersunk hole 51 is arranged in the connecting ears 52, and the axis centers of the first countersunk holes 51 in the two connecting ears 52 coincide.

[0027] The screw 1 is provided with an external thread, and the first countersunk hole 51 is provided with an internal thread adapted to the screw 1 .

[0028] like Figure 3-5As shown, a rotating lifting ring, which applies the above-mentioned braking device, also includes a support sleeve 6 and a bolt 7. The bolt 7 passes through the ring base 5 and is fixed by the support sleeve 6. The top of the support sleeve 6 is inserted into the ring base 5, and the inner wall of the support sleeve 6 is provided with an internal thread compatible with the bolt 7.

[0029] When in use, the bolt 7 is fixed to the heavy object to be lifted, the hook is hung on the ring body 4, and the rotation angle of the ring body 4 can be adjusted by pulling the ring body 4 to form a stop.

[0030] When the braking device needs to be replaced, use a screwdriver to tighten the screw 1 and remove the screw 1 from the ring base 5. Then, the baffle 2, wave spring 3, and ring body 4 can be disassembled one by one, and the required accessories can be replaced as needed. The screw 1 is passed through the baffle 2, wave spring 3, and ring body 4 in turn, and the screw 1 is tightened with a screwdriver to fix the screw 1 on the ring base 5.

[0031] If the braking function of the ring body 1 is not required in some situations, remove the wave spring 3 after removing the screw 1, pass the screw 1 through the baffle 2 and the wave spring 3 in sequence, and tighten the screw 1 with a screwdriver to fix the screw 1 on the ring body base 5.
