[0002] The steel structure frame is a structure mainly made of steel, which is one of the main building structure types. It has the characteristics of high strength, light self-weight, and large stiffness. Therefore, it is particularly suitable for building large-span, ultra-high, and super-heavy buildings; the material has good homogeneity and isotropy, belongs to an ideal elastic body, and most conforms to the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformations, and can well withstand dynamic loads; its disadvantage is poor fire resistance and corrosion resistance.

Moreover, the length of each section of the steel frame structure is constant. In some scenarios that require rapid erection, the steel frame structure with a constant length cannot meet the erection requirements, and on-site processing and correction are needed, which is cumbersome and seriously affects work efficiency.

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0022] An embodiment of the present utility model provides a steel frame structure that is convenient for calibration, as Figures 1-4 shown, including: main frame 1, first support frame 2, second support frame 3, lifting mechanism 4, and winding and unwinding mechanism 5;

[0023] The first support frame 2 is slidably connected inside the main frame 1, the second support frame 3 is slidably connected inside the first support frame 2, the lifting mechanism 4 is connected to the main frame 1, the first support frame 2, and the second support frame 3, and the winding and unwinding mechanism 5 is arranged on one side of the main frame 1 and connected to the lifting mechanism 4;

[0024] The lifting mechanism 4 includes a supporting seat 41, guiding wheels 42, and a docking seat 43. The supporting seat 41 is respectively connected to the tops of the main frame 1 and the first support frame 2. The guiding wheels 42 are rotatably connected to one end of the supporting seat 41 and are symmetrically arranged. The docking seat 43 is connected to the supporting seat 41.

[0025] It should be noted that, since most of the existing steel frame structures adopt a stacking construction method, a lifting device is required to stack and stack them layer by layer during construction, and the length of each section of the steel frame structure is constant. In some scenarios that require rapid construction, the steel frame structure of constant length cannot meet the construction requirements, and it needs to be processed and corrected on site. The operation is cumbersome and seriously affects work efficiency. In order to solve this problem, a lifting mechanism 4 and a winding and unwinding mechanism 5 are set in the present scheme. By setting multiple frames as a sliding connection structure, and combining the lifting mechanism 4 and the winding and unwinding mechanism 5 to lift the steel frame as a whole, the height of the steel frame structure as a whole can be quickly adjusted. It is simple and efficient. When the height needs to be corrected, the steel cable in the lifting mechanism 4 can be wound and unwound by the winding and unwinding mechanism 5, so that the steel frame structure can be suitable for different usage scenarios, and the application range is wide. The movable pulley structure in the lifting mechanism 4 can reduce the traction force of the winding and unwinding mechanism 5, so that it can quickly drive the lifting mechanism 4 to work together.

[0026] Specifically, in this embodiment, this scheme mainly includes a main frame 1, a first branch frame 2, a second branch frame 3, a lifting mechanism 4 and a winding and unwinding mechanism 5. When in use, the first adjusting steel cable 44 is wound by the winding disk 52 in the winding and unwinding mechanism 5, and then the first adjusting steel cable 44 drives the first branch frame 2 to slide in the main frame 1. While the first branch frame 2 slides, the docking seat 43 on the first branch frame 2 moves upward synchronously, and the second branch frame 3 is driven to move upward synchronously by the second adjusting steel cable 45 and the second adjusting steel cable 45.

[0027] In a further preferred embodiment of the present invention, Figures 1-4 As shown, the lifting mechanism 4 also includes a first adjusting steel cable 44 and a second adjusting steel cable 45.

One end of the second adjusting steel cable 45 is fixed to the bottom of the second support frame 3, and the other end passes around the guide wheel 42 on the first support frame 2 and is connected to the docking seat 43.

[0028] In this embodiment, the height of the entire steel frame is quickly corrected and adjusted by the first adjustment steel cable 44 and the second adjustment steel cable 45.

The reel 52 is rotatably connected to the protrusion, and one end of the first adjustment cable 44 is wound and connected to the reel 52.

[0030] In this embodiment, the first adjusting steel cable 44 is wound and unwound by the winding reel 52.

The worm gear 55 is coaxially connected to one side of the winding reel 52, and the worm 54 meshes with the worm gear 55.

[0032] In this embodiment, the servo motor 53 drives the worm 54 to rotate, thereby driving the worm gear 55 to engage and move synchronously, and driving the winding reel 52 to rotate synchronously.

[0033] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the supporting seat 41 is detachably connected to the main frame 1 and the first supporting frame 2 respectively by screws.
