[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1-2 As shown, a hydraulic tilting mechanism for welding box-shaped steel components includes a fixed base 1. A guide rail 2 is symmetrically installed on one side of the fixed base 1 near the bottom end. A slidable movable base 3 is installed on the guide rail 2. In order to facilitate the positioning of the movable base 3 after sliding to a suitable position, in this embodiment, a plurality of positioning holes 9 distributed along its length direction are opened on the side wall of the guide rail 2. A detachable positioning pin 10 is provided on the side wall of the movable base 3, and the positioning pin 10 is inserted into one of the corresponding positioning holes 9.

[0020] like Figures 2-3 As shown, the top of both the fixed seat 1 and the movable seat 3 are connected to a support ring 4. A turntable 5 is rotatably installed inside the support ring 4. Positioning mechanisms 7 for clamping box-shaped steel components 6 are installed on the opposite sides of the two turntables 5. The positioning mechanism 7 includes a lower U-shaped plate 71, an upper U-shaped plate 72, a threaded component 73, a clamping plate 74, and a fixing component 75. The lower U-shaped plate 71 is fixedly connected to the side wall of the turntable 5. The upper U-shaped plate 72 is rotatably connected to the lower U-shaped plate 71. After the upper U-shaped plate 72 and the lower U-shaped plate 71 are enclosed, the position is locked by the fixing component 75. The threaded component 73 is threadedly connected to the top of the upper U-shaped plate 72 and the two sides of the lower U-shaped plate 71 respectively. The clamping plate 74 is rotatably connected to the end of the threaded component 73.

[0021] It should be noted that the upper U-shaped plate 72 is connected with the lower U-shaped plate 71 through a hinge, and the upper U-shaped plate 72 is deflected to separate from the lower U-shaped plate 71, at this time, the upper side of the lower U-shaped plate 71 is in an open state, facilitating the placement of the end of the box-shaped steel member 6 in the lower U-shaped plate 71, and the upper U-shaped plate 72 is deflected to form an enclosed state with the lower U-shaped plate 71, and the position of the upper U-shaped plate 72 can be locked by the fixing member 75, and the position of the clamping plate 74 is adjusted by rotating the threaded member 73, so that the box-shaped steel member 6 is positioned and clamped, and displacement and shaking do not occur during subsequent overturning.

[0022] As shown in Figure 3 , it can be understood that the specific structure of the fixing member 75 and the installation method thereof are not limited in the present application, and only one specific structure is provided below for reference. The fixing member 75 includes two positioning blocks 751 and a bolt 752 with a nut, and the two positioning blocks 751 are fixedly connected with the side walls of the upper U-shaped plate 72 and the lower U-shaped plate 71, respectively. When the upper U-shaped plate 72 and the lower U-shaped plate 71 are enclosed, the two positioning blocks 751 are connected by the bolt 752.

[0023] It should be noted that a through hole is provided through the positioning block 751 for the bolt 752 to pass through, and when the upper U-shaped plate 72 and the lower U-shaped plate 71 are in an enclosed state, the bolt 752 is passed through the through holes in the two positioning blocks 751, and then the nut is tightened to lock the position of the upper U-shaped plate 72.

[0024] As shown in Figure 1 and Figure 4 , the fixed seat 1 is provided with a hydraulic mechanism 8 for driving the rotation of the rotating disc 5, and the hydraulic mechanism 8 includes a hydraulic cylinder 81, a rack 82 and a gear 83. A placing groove 11 for installing the hydraulic cylinder 81 is provided through one side of the fixed seat 1, the piston rod of the hydraulic cylinder 81 extends into the support ring 4 and is connected with the rack 82, the gear 83 is engaged with the rack 82, and the gear 83 is coaxially connected with the rotating disc 5 through a pin shaft.

[0025] It should be noted that when the hydraulic cylinder 81 is started, the lifting stroke of the rack 82 can be controlled synchronously by controlling the piston rod stroke of the hydraulic cylinder 81, and the rotating disc 5 connected with the gear 83 will be driven to rotate during the movement of the rack 82, thereby realizing the overturning of the box-shaped steel member 6.

[0026] As shown in Figure 1 and Figure 4 , a through groove 12 is provided through the rack 82 and distributed along the length direction of the rack 82, a matching guide pin 13 is inserted into the through groove 12, a connecting arm 14 is fixedly installed on the inner side wall of the support ring 4, and the guide pin 13 is fixedly connected with the connecting arm 14.

[0027] It needs to be explained that the sliding guide structure is formed by the guide pin 13 matched with the through groove 12, which can effectively ensure the stability of the rack 82 lifting, and the connecting arm 14 is used to conveniently connect the guide pin 13 with the inner side wall of the support ring 4, thereby ensuring the stability of the position of the guide pin 13.

[0028] The above embodiments are only used to illustrate the technical method of the utility model and not to limit, although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical method of the utility model.
