[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] Combine Figures 1 - 4 A lifting bracket for a lifting frame includes an adjusting component 2 arranged on a supporting platform 1, and the adjusting component 2 has a turntable 3 and a driving gear 13.

[0024] See also Figure 2 and Figure 3 , it is further obtained that the turntable 3 is rotatably installed on the top of the support platform 1, and a support beam 5 is rotatably installed at the front position of the top of the turntable 3 through a swivel seat 4. A hydraulic cylinder 1 6 is provided at the upper position inside the support beam 5, and a movable beam 8 is installed at the top of the hydraulic cylinder 1 6 through a telescopic rod 7. A limiting pulley 9 is movably installed on the top of the movable beam 8, and a steel wire rope 10 is provided on the outer ring of the limiting pulley 9. The front end of the steel wire rope 10 is connected to a hook 11. Hydraulic cylinders 2 16 are movably installed on both sides of the top of the turntable 3, and the push rod ends of the two hydraulic cylinders 2 16 are movably connected to the rear end of the support beam 5. The support beam 5 is arranged in a "冂" shape, and the bottom end of the support beam 5 does not contact the top surface of the turntable 3.

[0025] Specifically, by means of the telescopic rod 7 on the first hydraulic cylinder 6 extending to drive the movable beam 8 to rise, the limit pulley 9 installed on the movable beam 8 can be lifted, thereby changing the rising distance of the hook 11, facilitating personnel to change the lifting height of the object as needed. At the same time, the height between the support beam 5 and the movable beam 8 is adjustable. When not in use, the movable beam 8 can be retracted by means of the telescopic rod 7 retracting. At the same time, by means of the push rod of the second hydraulic cylinder 16 retracting, the angle of the support beam 5 can be adjusted. The support beam 5 can be adjusted to a non-vertical state, and by reducing the overall height, the overall occupied space during storage can be reduced. At the same time, in occasions with a relatively low lifting height, by adjusting the angle of the support beam 5 and the extending distance of the movable beam 8, the lifting distance can be increased. An electric control box 15 is provided on one side of the support platform 1, and the electric control box 15 is electrically connected to the second hydraulic cylinder 16, the adjusting motor 14, and the first hydraulic cylinder 6.

[0026] Embodiment 2

[0027] Refer to Figure 2 、 Figure 3 and Figure 4 On the basis of Embodiment 1, it is further obtained that an adjusting motor 14 is installed on one side of the support platform 1 through a mounting plate. The driving gear 13 is installed at the top of the driving shaft of the adjusting motor 14. A driven gear 12 adapted to match the driving gear 13 is provided near the lower part of the outer ring of the turntable 3. The adjusting motor 14 is meshed with the turntable 3 through the driving gear 13 and the driven gear 12, and the upper part of the turntable 3 does not contact the driving gear 13.

[0028] Specifically, by controlling the adjusting motor 14 to start through the electric control box 15 and driving the driving gear 13 to rotate by its driving shaft, the turntable 3 can be driven to rotate on the support platform 1 through meshing transmission, thereby adjusting the orientation of the support beam 5 and changing the direction of the hook 11, so that personnel can adjust the lifting direction according to the work needs and lift the object to a suitable position.

[0029] During the actual operation process, after fixing the support platform 1 on an external support device and fixing it at a suitable construction position, by means of the telescopic rod 7 on the first hydraulic cylinder 6 extending to drive the movable beam 8 to rise, the limit pulley 9 installed on the movable beam 8 can be lifted, thereby changing the rising distance of the hook 11, facilitating personnel to change the lifting height of the object as needed;

[0030] Meanwhile, the height of the supporting beam 5 and the movable beam 8 is adjustable. When not in use, the movable beam 8 can be retracted by retracting the telescopic rod 7. At the same time, the angle of the supporting beam 5 can be adjusted by retracting the push rod of the second hydraulic cylinder 16. By making the supporting beam 5 in a non-vertical state, the space occupied during storage can be reduced. At the same time, in the case of a lower lifting height, by adjusting the angle of the supporting beam 5 and the extending distance of the movable beam 8, the lifting distance can be increased, and the use flexibility is relatively high.

[0031] Moreover, by starting the adjusting motor 14 to drive the rotation of the driving gear 13, the turntable 3 can be driven to rotate on the support platform 1 through meshing transmission, so that the orientation of the supporting beam 5 can be adjusted, and thus the direction of the hook 11 can be changed, so that the operator can adjust the lifting direction according to the work needs, and then lift the object to the appropriate position. The adjustment process can be carried out after the external support feet are fixed, without changing the overall orientation of the support platform 1.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
