As shown in fig. 1, the present embodiment provides a turn-over lug which can be used during erection of a pile foundation 6 in pile sinking construction. Specifically, it includes a lug plate 1, a lug plate reinforcing plate 2, and a stopper 3. Wherein, the lifting lug plate 1 is configured to be arranged on the pile foundation 6, a first lug hole 11 is arranged on the lifting lug plate 1, and the first lug hole 11 is configured to be rotatably connected with the shackle 5. When the turnover rope 7 is contracted, the shackle 5 can rotate on the lug plate 1 while pulling the lug plate 1 so as to continuously adapt to the change of the interaction force between the pile foundation 6 and the turnover rope 7. One end of the limiting part 3 is arranged on the lug plate 1, the other end of the limiting part extends towards the direction far away from the lug plate 1, and the shackle 5 can rotate under the action of gravity and is attached to the limiting part 3 in a leaning mode. Before the turning rope 7 is contracted, the shackle 5 naturally sags under the action of gravity. When the turning rope 7 contracts and pulls the shackle 5, the limiting piece 3 can limit the shackle 5 to rotate towards the non-working direction and can rotate towards the working direction from the limiting piece 3. Therefore, the tension provided by the turnover rope 7 is not easy to block the shackle 5 and the limiting part 3 at reverse fixed positions, and is beneficial to erecting the pile foundation 6 by constructors. Meanwhile, the shackle 5 can still rotate in a certain angle in a self-adaptive manner, so that the phenomenon of locking between the shackle 5 and the turnover lifting lug is avoided, the process time for disassembling the lifting point is shortened, and the operation risk is reduced.

As shown in fig. 2-3, in order to prevent the lifting lug plate 1 from being damaged due to stress during the working process, the turnover lifting lug further comprises a pair of lifting lug plate reinforcing plates 2, the lifting lug plate reinforcing plates 2 are arranged in pairs, at least one pair of lifting lug plate reinforcing plates is arranged, and each lifting lug plate reinforcing plate 2 is respectively arranged on two sides of the lifting lug plate 1. Each lug plate reinforcing plate 2 supports the lug plate 1 in the thickness direction of the lug plate 1, so that the structural strength of the turnover lifting lug is improved. In this embodiment, the pair of ear plate reinforcing plates 2 are symmetrically arranged on two sides of the lifting ear plate 1, and are perpendicular to the lifting ear plate 1, so that the structure is stable.

As shown in fig. 4, in the present embodiment, two pairs of ear plate reinforcing plates 2 are provided, and the two pairs of ear plate reinforcing plates 2 are provided on the ear plate 1 at intervals along the length direction of the ear plate 1. The two pairs of ear plate reinforcing plates 2 can provide a plurality of supports for the ear plate 1 in the length direction of the ear plate 1. Therefore, when the turning-over lifting lug is pulled by the shackle 5, the structure of the lifting lug plate 1 is not easy to deform. Optionally, the first ear hole 11 is located between two pairs of ear plate reinforcing plates 2. The deflection moment generated by the pulling force applied to the lug plate 1 by the shackle 5 can always act on one lug plate reinforcing plate 2, and the lug plate 1 has high structural strength and is not easy to damage.

The periphery of the first ear hole 11 is used as a force application area of the shackle 5 and is a position on the turnover lifting lug which is easy to lose efficacy. In order to protect the area and improve the structural strength of the turnover lifting lug, as shown in fig. 2-4, optionally, the turnover lifting lug further comprises two lug hole reinforcing plates 4, the two lug hole reinforcing plates 4 are provided in pairs, and the two lug hole reinforcing plates 4 are respectively attached to two sides of the lifting lug plate 1. For not influencing the installation use of shackle 5 in first earhole 11 department, all seted up second earhole 41 on each otic placode reinforcing plate 2, each second earhole 41 and first earhole 11 are all coaxial. In the present embodiment, the ear hole reinforcing plate 4 has an annular shape. During assembly, the positioning can be completed only according to the relative position of the second ear hole 41 and the first ear hole 11, and the installation is convenient.

The limiting piece 3 is arranged at a position close to the first ear hole 11, so that the shackle 5 can be limited conveniently. However, when the limiting member 3 is subjected to an excessive force, it is likely to affect the first ear hole 11. Therefore, in the present embodiment, the limiting member 3 is disposed on the ear hole reinforcing plate 4 away from the first ear hole 11. Specifically, the limiting member 3 is a steel plate welded to the ear hole reinforcing plate 4. The welded connection does not need to punch and drill holes on the lug plate reinforcing plate 2, so that labor and time are saved, the sectional area of the lug plate reinforcing plate 2 is not reduced, materials are fully utilized, and the connection strength is high.

To facilitate the limiting of the shackle 5, optionally, the limiting member 3 is arranged vertically on the ear hole reinforcing plate 4. When the shackle 5 rotates under the action of gravity, the part of the shackle 5 positioned on one side of the lug plate 1 is attached to the limiting part 3, so that the shackle 5 is prevented from being locked on the turning-over lifting lug due to continuous reverse rotation. Optionally, two limiting members 3 are provided, and each limiting member 3 is respectively disposed on the ear hole reinforcing plates 4 on two sides of the ear hanging plate 1. The two limiting parts 3 are respectively used for blocking one side of the shackle 5, the balance of the shackle 5 is good, and the situation that the shackle 5 is blocked with the lug plate 1 and even the structures of the shackle and the lug plate are damaged due to deflection in the direction perpendicular to the rotation direction of the shackle is avoided.
