[0004] However, the existing roadbed plate lifting point structure has the problems of complex manufacturing process, high welding requirement, large welding amount, easy interference between the lifting point position and the lifting belt, and large operation difficulty of the steel wire rope hook. UTILITY MODEL CONTENTS

[0005] The utility model discloses a general roadbed plate hidden lifting point structure which solves the problems of complex manufacturing process of the roadbed plate lifting point structure, easy interference between the lifting point position and the lifting belt and large operation difficulty of the steel wire rope hook.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] A general roadbed plate hidden lifting point structure, comprising a roadbed plate body, a cavity is formed in the bottom of the roadbed plate body, a plurality of through openings are symmetrically arranged on the top of the roadbed plate body, and a lifting rod is fixedly connected in each through opening.

[0008] Preferably, a swivel ring is rotatably connected to the lifting rod.

[0009] Preferably, two arc-shaped plates are symmetrically arranged in the through opening and are rotatably connected to the through opening through a rotating shaft, a torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are respectively abutted against the arc-shaped plates and the inner wall of the through opening.

[0010] Preferably, a plurality of reinforcing rods are fixedly connected in the cavity.

[0011] Preferably, a plurality of wedge-shaped reinforcing plates are fixedly connected to the inner side wall of the cavity.

[0012] Preferably, the number of the through openings is four.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The concealed lifting point structure in this invention can effectively reduce the processing and manufacturing cost of the lifting points, eliminate habitual violations by operators, and avoid unsafe behaviors. At the same time, the hook is easy to attach and the operation is simple, making it suitable for various complex situations. It also avoids contact interference between the lifting sling and the roadbed plate, reduces damage to the lifting sling, and reduces the occurrence of accidents. Attached Figure Description
