The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

A bracket device used for lifting large-segment steel beams at sea, as shown in Figures 1 to 7, includes a positioning beam 1, a first support leg 2 arranged at one end of the positioning beam 1, and a buffer pad 4 arranged at the other end of the positioning beam 1, a three-way jack 13 is arranged at a position corresponding to the buffer pad 4 on the positioning beam 1; a second support leg 3 is arranged at a position close to the buffer pad 4 on the positioning beam 1, and there is an accommodating gap between the second support leg 3 and the buffer pad 4, an upper stop beam 6 is arranged at a position corresponding to the top of the second support leg 3 on the positioning beam 1, and a lower stop beam 7 is arranged at a position corresponding to the bottom of the second support leg 3 on the positioning beam 1, the upper stop beam 6 and the lower stop beam 7 are connected by a connecting rope 5, and there is a limiting gap between the lower stop beam 7 and the second support leg 3, and at least four connecting ropes 5 are evenly arranged around the second support leg 3.

Exemplarily, the buffer pad 4 can adopt the pad or rubber pad used in the existing construction process to achieve a buffering and protective effect when the positioning beam 1 contacts the erected beam section 10, avoiding direct contact between the positioning beam 1 and the erected beam section 10 and causing damage to the erected beam section 10, which is beneficial to improving the safety of the construction process.

Optionally, at least two upper stop beams 6 are provided, and the length direction of each upper stop beam 6 is perpendicular to the length direction of the positioning beam 1; at least two lower stop beams 7 are provided, and the length direction of each lower stop beam 7 is uniform and the same as the length direction of the positioning beam 1. By setting the length directions of the upper stop beam 6 and the lower stop beam 7 differently, it is helpful to improve the coordination stability of the upper stop beam 6 and the lower stop beam 7, thereby ensuring that the connecting rope 5 can continuously and stably tighten and limit the lower stop beam 7.

Four evenly provided connecting ropes 5 can achieve stable position limiting of the lower guard beam 7. In addition, those skilled in the art can also select a suitable number of upper guard beams 6, lower guard beams 7 and connecting ropes 5 according to actual needs to achieve position limiting of the beam section 9 to be erected, which will not be repeated here.

Exemplarily, the positioning plate 19 is fixed below the positioning beam 1, and two, four or more reinforcement members 14 can be arranged at intervals, and each reinforcement member 14 is a T-shaped structural member, and the vertical end of the reinforcement member 14 is fixedly connected to the positioning plate 19 and the positioning beam 1, and the horizontal ends of each reinforcement member 14 are fixedly connected, and the horizontal ends of each reinforcement member 14 are fixedly connected to the top of the positioning beam 1. By arranging the positioning plate 19 at the position corresponding to the buffer block 4 on the positioning beam 1, and arranging the reinforcement member 14 for strengthening the structural strength of the connection between the positioning plate 19 and the positioning beam 1, the positioning plate 19 can better support and limit the buffer block 4.

In actual application, the end plate 17 of the support column 15 facing the positioning beam 1 is a U-shaped structural member, and positioning bolts 18 are provided on the left and right sides of the end plate 17. Specifically, the U-shaped end plate 17 can cooperate with the positioning beam 1 to ensure that the first leg 2 and the second leg 3 can always stably support the positioning beam 1, avoid the first leg 2 and the second leg 3 from being misaligned with the positioning beam 1 during the hoisting process, and ensure the stability of the positioning beam 1 during the hoisting process.

In addition, threaded holes cooperating with the positioning bolts 18 are provided on the left and right sides of the end plate 17, and a plurality of threaded holes can be provided at intervals, so as to facilitate the installation of a plurality of positioning bolts 18, so as to improve the limiting effect of the positioning bolts 18 on the first leg 2 or the second leg 3. By installing the positioning bolts 18, the positioning bolts 18 can not only further limit the first leg 2 or the second leg 3 by supporting the positioning beam 1, but also the positioning bolts 18 can cooperate with the edge of the lower end of the positioning beam 1 to prevent the first leg 2 or the second leg 3 from being separated from the positioning beam 1.

In actual use, by setting the positioning bolts 18, it is convenient to assemble the first leg 2 and the second leg 3, and it is also convenient for construction personnel to adjust the positions of the first leg 2 and the second leg 3 according to actual needs, so that the first leg 2 and the second leg 3 can both correspond to the diaphragm 8 or the web on the beam section 9 to be erected, which is beneficial to improve the stability and safety of the beam section 9 to be erected during the lifting process.

Optionally, the support column 15 is a hollow tubular structure. Compared with other structures, the hollow tubular support column 15 is light in weight and is convenient for hoisting construction.
