The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0038] In the description of the present invention, if there are descriptions of first, second, third, fourth, fifth, etc., they are only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0039] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0040] In the present invention, unless otherwise expressly defined, terms such as "disposed," "installed," and "connected" should be interpreted broadly. For example, they may refer to direct connection or indirect connection through an intermediate medium; fixed connection or detachable connection or integral molding; mechanical connection; and internal communication between two components or interaction between two components. Those skilled in the art can reasonably determine the specific meanings of these terms in the present invention based on the specific content of the technical solution.

[0041] Reference Figures 1 to 8 An embodiment of the present invention provides a positioning device for supporting an H-shaped steel with a base and for driving the four sides of the H-shaped steel to be positioned upward in sequence. The positioning device includes a mounting frame 100, a rotating mechanism 200, and a moving mechanism 300.

[0042] The rotating mechanism 200 is provided on the mounting frame 100. The rotating mechanism 200 is used to support the H-shaped steel located at the first position S1 with one side facing upward, and is used to rotate the H-shaped steel to the second position S2 so that the H-shaped steel is located upward along the lower side away from the rotation direction. The moving mechanism 300 is provided on the mounting frame 100. The moving mechanism 300 is used to move the H-shaped steel located at the second position S2 to the first position S1.

[0043] It can be understood that, for the convenience of description, the H-shaped steel refers to an H-shaped steel with a base.

[0044] It can be understood that the corresponding side of the H-shaped steel on which the base is mounted is arranged upwards, so that the workers can perform welding work on the abutment portion of the side.

[0045] It is understood that when the moving mechanism 300 transfers the H-beam located at the second position S2 to the first position S1, the rotating mechanism 200 resets to receive and support the H-beam transferred by the moving mechanism 300. Specifically, if the rotating mechanism 200 supports the H-beam located at the first position S1 with side a facing upward, and the rotating mechanism 200 rotates the H-beam to the second position S2 so that the H-beam is positioned upward along the lower side, i.e., side b, which is away from the rotation direction, the moving mechanism 300 transfers the H-beam located at the second position S2 to the first position S1, the rotating mechanism 200 resets to receive and support the H-beam transferred by the moving mechanism 300 with side b facing upward.

[0046] It should be noted that the rotating mechanism 200 receives and supports the adjusted H-shaped steel, and the rotating mechanism 200 can drive the adjusted H-shaped steel to rotate to the second position S2 so that it is set upward along the corresponding lower side away from the rotation direction.
