[0007] By adopting the above technical solution, the inclined columns can strengthen and fix the herringbone mast frame, and the installation position of the inclined columns basically does not affect the vertical space during the operation of the lifting equipment.

[0008] Preferably, one end of the mast unit away from the inclined column is fixedly connected with a mounting plate, the mounting plate abuts against the side wall of the building frame column, and the mounting plate is penetrated by chemical bolts, which pass through the mounting plate and are inserted into the building frame column.

[0011] By adopting the above technical solution, the mounting ear plate provides a connection point at the upper ends of the two mast monomers on the side wall of the inclined column, thereby realizing the connection with the herringbone mast frame without affecting the structure of the inclined column.

[0012] Preferably, a mounting steel plate is provided on the top of the building frame column, and one end of the inclined column close to the building frame column is welded to the mounting steel plate.

[0019] By adopting the above technical solution, when the safety rope is in a tensioned state, a force analysis of the mounting frame shows that the tension applied by the safety rope to the winch and the placement plate causes the placement plate to have a tendency to flip relative to the connecting plate. At this time, the reinforcement rod is subjected to pressure from the placement plate, which in turn generates a thrust on the connecting plate, causing the connecting plate to more closely abut against the building frame column, thereby improving the state stability of the safety mounting frame and the mounting steel plate relative to the building frame column.

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The present application embodiment discloses a herringbone mast hoisting device, such as Figure 1 As shown, it includes a herringbone mast frame 2, an inclined column 3, an electric hoist 7 and a safety mechanism 4. The herringbone mast frame 2 and the inclined column 3 constitute the main fixed frame of the lifting equipment, the electric hoist 7 is used for lifting operations, and the safety mechanism 4 is used to improve the overall stability and safety of the lifting equipment.

[0028] like Figure 1 and 2As shown, the herringbone mast frame 2 and the inclined column 3 are both fixedly installed on the top of the building frame column 1. The herringbone mast frame 2 includes two mast monomers 21, the length directions of the two mast monomers 21 are staggered, one end of the mast monomer 21 is welded and fixed with a mounting plate 22, the mounting plate 22 is abutted against the outer side wall of the building frame column 1, and a chemical bolt 6 is passed through the mounting plate 22 and inserted into the building frame column 1. The lower ends of the two mast monomers 21 are respectively fixed to the building frame column 1 through the chemical bolt 6. A mounting steel plate 33 is provided on the top of the building frame column 1, one end of the inclined column 3 is welded to the mounting steel plate 33, and the other end is inclined to one side of the mast monomer 21; the upper ends of the two mast monomers 21 are close to each other, and the side wall of the inclined column 3 is fixedly connected with an assembly ear plate 31. The herringbone mast frame 2 also includes an assembly bolt 23, which passes through the two mast monomers 21 and the assembly ear plate 31 at the same time and is threadedly connected with a nut. In the projection along the vertical direction, the connection point between the inclined column 3 and the building frame column 1 is located within the angle formed by the two mast monomers 21, that is, the inclined column 3 does not affect the horizontal space outside the building frame column 1 and the herringbone mast frame 2.

[0029] like Figure 1 and 2 As shown, the side of the mounting steel plate 33 close to the herringbone mast frame 2 is fixedly connected with an auxiliary plate 34, and the side away from the herringbone mast frame 2 is fixedly connected with a safety mounting frame 5. The auxiliary plate 34 abuts against the side wall of the building frame column 1, and the auxiliary plate 34 is penetrated with a chemical bolt 6, which passes through the auxiliary plate 34 and is inserted into the building frame column 1. The auxiliary plate 34 and the safety mounting frame 5 form a sandwich state for the building frame column 1, and the safety mechanism 4 includes a winch 41 and a safety rope 42; the winch 41 is installed on the safety mounting frame 5, and the top of the inclined column 3 is rotatably connected with a direction-changing wheel 35, and the axis of the direction-changing wheel 35 is in the horizontal direction; the winch 41 is wound with a safety rope 42, and the end of the safety rope 42 away from the winch 41 bypasses the phase-changing wheel and is fixed on the concrete column or beam that has been formed in the building, and the top of the inclined column 3 is dragged by the safety rope 42, thereby strengthening the stability of the force state of the inclined column 3.

[0030] like Figure 1 and 2As shown, the insurance mounting frame 5 includes a connecting plate 51, a placement plate 52 and a rib rod 53. The connecting plate 51 is directly welded and fixed to the mounting plate 22, and the two plate surfaces are perpendicular to each other. The plate surface of the connecting plate 51 is in contact with the side of the building frame column 1 away from the auxiliary plate 34. The placement plate 52 is fixedly connected to the connecting plate 51, and the two plate surfaces are perpendicular to each other. The winch 41 is arranged on the placement plate 52. One end of the rib rod 53 is fixedly connected to the placement plate 52, and the other end is fixedly connected to the connecting plate 51. The end of the rib rod 53 connected to the connecting plate 51 is higher than the end connected to the placement plate 52. When the safety rope 42 is in a tensioned state, a force analysis of the mounting frame shows that the tension applied by the safety rope 42 to the winch 41 and the placement plate 52 causes the placement plate 52 to tend to flip upward relative to the connecting plate 51. At this time, the rib rod 53 is subjected to pressure from the placement plate 52, thereby generating a thrust on the connecting plate 51, causing the connecting plate 51 to more closely abut against the building frame column 1, thereby improving the stability of the safety mounting frame 5 and the mounting steel plate 33 relative to the building frame column 1.

[0031] like Figure 1 As shown, a lifting ring 32 is welded and installed on the top of the inclined column 3, which is used as a lifting point for the electric hoist 7.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
