[0035] Please refer to Figure 1-Figure 5 A steel structure welding operation protection platform provided in an embodiment of the present application includes an operation platform 1 and a lifting device 2, wherein the operation platform 1 includes a platform A11 and a platform B12, wherein the platform A11 and the platform B12 are assembled and surround the steel structure column 6 to be welded, and the lifting device 2 is respectively connected to the platform A11 and the platform B12 to drive the platform A11 and the platform B12 to move up and down, and a connecting structure is provided between the platform A11 and the platform B12 and the steel structure column 6 so that a fixed connection can be formed between the platform A11 and the platform B12 and the steel structure column 6 when the platform A11 and the platform B12 are raised to the weld position C.

[0036] In the above scheme, the platform A and the platform B can be respectively raised to the welding position of the steel structure column by the lifting device. The platform A and the platform B are assembled to form an operating platform surrounding the steel structure column to be welded, which is convenient for welding around the steel structure column. At the same time, a connecting structure is arranged between the platform A and the platform B and the steel structure column to ensure the stable connection between the operating platform and the steel structure column during welding. The protective platform can be assembled quickly and can be repeatedly used. It is economical and cost-effective, can effectively shorten the project construction period, reduce the project construction cost, and ensure safe and reliable construction.

[0037] According to some embodiments of the present application, a latch structure is provided between the platform A11 and the platform B12 to connect them to form a whole after being assembled. By providing the latch structure, after the platform A and the platform B are connected to the steel structure column during use, the latch can be used to connect the platform A and the platform B to each other, further ensuring the safety of the operation platform construction.

[0038] According to some embodiments of the present application, the latch structure includes a socket 31 provided on the platform A11, and a movable latch 32 provided on the platform B12. Specifically, two sockets 31 are provided on each side of the platform A11, and the two sockets 31 on each side are arranged at intervals along the vertical direction. At the same time, movable latches 32 are provided at corresponding positions on the platform B12, for a total of four movable latches 32. After the platform A11 and the platform B are assembled 12, the connection between the platform A11 and the platform B12 is achieved by inserting the movable latch 32 into the socket 31. It can be understood that the positions of the socket and the movable latch can be exchanged, that is, the socket is provided on the platform B, and the movable latch is provided on the platform A.

[0039] According to some embodiments of the present application, the operating platform 1 is in a square structure, and has a through hole in the center adapted to the steel structure column 6. Specifically, the operating platform 1 may be in a square structure, and the internal through hole may be a square hole, and the size of the through hole is slightly larger than the diameter of the steel structure column 6, so as to smoothly surround the outside of the steel structure column 6.

[0040] According to some embodiments of the present application, the operation platform 1 is divided into two parts, the platform A11 and the platform B12, based on the center of the steel structure column 6. The platform A and the platform B formed in this way are similar to equal division, have similar structures, and are similar in weight, and the construction operation areas on the platform A and the platform B are roughly the same.

[0041] According to some embodiments of the present application, the connection structure includes a socket rod 41 disposed on the lower side of the platform A11 and the platform B12, and a socket hole 42 disposed on the outer circle of the steel structure column 6. When the platform A11 and the platform B12 are assembled, the socket rods 41 on the lower side of the platform A11 and the platform B12 are respectively inserted into the socket holes 42 on the outer circle of the steel structure column 6, which can limit the movement of the platform A and the platform B away from the steel structure column. Specifically, the socket rod 41 can be made of round steel with a diameter of 22 mm, and then welded to the platform A11 and the platform B12.

[0042] According to some embodiments of the present application, a cross bar 411 is radially arranged on the socket vertical rod 41, and after the socket vertical rod 41 is inserted into the socket hole 42 on the outer circle of the steel structure column 6, the cross bar 411 abuts against the upper end of the socket hole 42. By providing the cross bar, the insertion depth of the socket vertical rod in the socket hole can be limited. After the cross bar is designed to contact the upper end of the socket hole, it can serve as a load-bearing support point of the operating platform to prevent the operating platform from falling.

[0043] According to some embodiments of the present application, the socket 42 is formed by bending a round steel into a U-shape and welding its opening to the outer wall of the steel structure column 6. The formation method of the socket is simple. Specifically, a round steel with a diameter of 25 mm can be bent and formed and then welded to the outer wall of the steel structure column 6 to form two sockets 42, and the two sockets 42 are symmetrically arranged.

[0044] According to some embodiments of the present application, a guardrail 5 is arranged around the operating platform 1. By providing the guardrail, a fall prevention effect can be achieved, thereby better protecting the construction operators. Specifically, the guardrail 5 is made of round steel with a diameter of 22 mm and has a certain height from the operating table 1.

[0045] According to some embodiments of the present application, a patterned steel plate is laid on the operating platform 1. Specifically, the operating platform body can be formed by welding steel sections, and then 1.2 mm patterned steel plates are laid and welded on the operating platform body to form a table for construction workers to stand on.

[0046] According to some embodiments of the present application, the lifting device 2 may be an electric hydraulic lifting platform vehicle, so that the operating platform can be lifted to the socket position by using the sliding rails of the electric hydraulic lifting platform vehicle.

[0047] Before welding, platform A11 and platform B12 are respectively raised to the welding position of the steel structure column 6 by the lifting device 2. After platform A11 and platform B12 are assembled to form an operating platform 1 surrounding the steel structure column 6 to be welded, the steel structure column welding construction can be carried out. After welding is completed, platform A11 and platform B12 are separated and lowered to the ground by the lifting device 2 for dismantling.

[0048] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
