In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] Please refer to Figures 1-5 , the present application will be described in detail by the following embodiments:

[0029] The mounting and positioning device for the fabricated steel structure in the embodiment, as shown in the structures of Figure 1 and Figure 2 , is suitable for positioning and clamping the fabricated steel structure column 1. In the hoisting and mounting process, the upper end of the fabricated steel structure column 1 will swing, and the device can realize the fixation after the position alignment, thereby avoiding the instability problem of continuous hoisting. The movable shear lifting frame 2 in the embodiment is provided with a supporting plate 3, and the supporting plate 3 is provided with a mounting groove 301 at the corresponding mounting position.

[0030] Specifically, the core structure of the device for realizing the mounting and positioning function is two positioning assemblies 4, as shown in the structure of Figures 3-5 , which are rotatably connected between the two main brackets 41. In order to reduce the deflection angle of the main bracket 41 against the fabricated steel structure column 1 and improve the clamping range, a C-shaped support 42 with an opening facing the fabricated steel structure column 1 is connected above the main bracket 41, as shown in the structures of Figure 4 and Figure 5 .

[0031] It should be explained that in order to improve the ability of clamping the fabricated steel structure column 1 and improve the application range, the intermediate frame 43 is installed between the C-shaped supports 42 in the embodiment. Specifically, the intermediate frame 43 is provided with a mounting seat 431 and a rotating head 432 at two ends, respectively, and a hydraulic cylinder 44 connected with the output shaft of the main bracket 41 is installed at the mounting seat 431. In order to keep synchronous movement, a limiting slide rod 45 is installed at both ends of the rotating head 432, and the two C-shaped supports 42 can slide synchronously on the limiting slide rod 45 along with the opening and closing of the hydraulic cylinder 44.

[0032] The embodiment is hinged at the rotating head 432 to the abutting plate 46, which is structured with a trapezoidal groove structure and can be applied to clamp and position the fabricated steel structure column 1 with different diameters.

[0033] The abutting plate 46 needs to obtain external force to abut against the fabricated steel structure column 1, such as Figure 1 The positional relationship is shown in Figure 4 and Figure 5 The shaft 47 is slidingly installed at the outer end of the main bracket 41, and the driven bracket 48 is rotatably installed on the shaft 47 and located inside the outer end of the main bracket 41. The hinged seat 49 is connected to the shaft 47, and the lifting cylinder 410 is installed on the supporting plate 3 as a power source and connected to the hinged seat 49.

[0034] In order to further improve the reliability of the device clamping and positioning, the embodiment is provided with Figure 2 , Figure 3 The moving embedding groove 31 is arranged on the supporting plate 3, the fixed shaft 411 is fixedly installed at the outer end of the driven bracket 48, the clamping block head 412 is rotatably installed on the fixed shaft 411, and the clamping block head 412 is inserted into the moving embedding groove 31. That is, the main bracket 41 is lifted by the lifting cylinder 410 to clamp the fabricated steel structure column 1, and after installation is completed, it is reset and lifted by the lifting machine to be separated from the fabricated steel structure column 1.

[0035] It should be noted that if the present application involves directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications also change accordingly. It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
