[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-5 , as shown in the figure: This embodiment is a preferred implementation scheme in the present technical solution, a forklift rotating gantry, including a rotating component 1, and a gantry component 2 mounted on the upper part of the rotating component 1; the rotating component 1 includes a turntable 12 matched with the forklift body, a base plate 11 mounted and fixed on the outside of the turntable 12, and a support ring 13 fixed on the lower side of the base plate 11; the gantry component 2 includes a base frame 21 fixed to the upper side of the base plate 11, a gantry body 22 fixed to the upper side of the base frame 21, a support plate 24 movably connected to the inner side of the gantry body 22 via a roller 29, a bracket 25 fixed to the outer side of the support plate 24, a support arm 26 detachably mounted on the end of the bracket 25, and a cylinder 23 for lifting and lowering the bracket 25.

[0026] Further description of the above structure is as follows: the upper end of the turntable 12 is fixed to the upper side of the base plate 11 through fasteners, and a triangular support block is fixed on the circumference of the turntable 12, and the triangular support block is fitted and supported on the lower side of the base plate 11; the connecting end recessed at the lower end of the turntable 12 is connected to the rotating drive adapter of the forklift body, and the support ring 13 fixed on the lower side of the base plate 11 is movably connected to the forklift body.

[0027] A frame is fixed at the lower back of the gantry body 22, and a start controller is fixed on the upper side of the frame; the bottom of the main body of the cylinder 23 is fixed to the middle position of the lower part of the gantry body 22, and a receiving part 27 is fixed to the telescopic end of the cylinder 23, and a connecting rod 28 is passed through and fixed to the end of the receiving part 27, and the bottom of the connecting rod 28 is fixed to the ear seat fixed at the bottom of the back of the bracket 25; a slide groove is provided on the inner side of the gantry body 22, and the roller 29 is movably adapted and installed in the slide groove;

[0028] The support arm 26 is an L-shaped structure, and a protrusion is integrally provided at the end of the vertical branch of the support arm 26. The protrusion is buckled with the edge of the bracket 25, and the protrusion is fixed to the edge of the bracket 25 via a fastener; a reinforcing plate is fixed between the upper and lower parallel beams of the bracket 25, and the lower part of the bracket 25 is suspended.

[0029] Further explanation of the above technical solution is as follows: in the rotating assembly 1, the turntable 12 cooperates with the forklift body, and its upper end is fixed to the upper side of the base plate 11 by fasteners (such as bolts) to ensure the stability of the rotating assembly 1, the base plate 11 is sleeved and fixed to the outside of the turntable 12, and a support ring 13 is fixed to the lower side to ensure a stable connection between the rotating assembly 1 and the forklift body. The support ring 13 is fixed to the lower side of the base plate 11 and is movably connected to the forklift body to ensure that the rotating assembly 1 can rotate smoothly. The triangular support block enhances the structural stability and strength of the entire rotating assembly 1. The rotating assembly 1 is used for the installation and fixation of the gantry assembly 2, and is also used to receive the rotation drive of the forklift body to achieve angle adjustment of the gantry assembly 2.

[0030] In the gantry assembly 2, the base frame 21 is fixed on the upper side of the base plate 11 as the basic support of the gantry body 22. The gantry body 22 is used to carry goods. The support plate 24 is movably connected to the inner side of the gantry body 22 through rollers 29 and can be raised and lowered as needed. The bracket 25 is fixed on the outer side of the support plate 24 and is used to install the support arm 26. The support arm 26 is an L-shaped structure and can be detachably installed on the end of the bracket 25. The protrusion at the end of its vertical branch is snapped with the edge of the bracket 25 and fixed with fasteners. The cylinder 23 is used to drive the lifting of the bracket 25. The bottom of the main body is fixed to the middle position of the lower part of the gantry body 22, and the telescopic end is connected to the ear seat fixed at the bottom of the back of the bracket 25 through the receiving member 27 and the connecting rod 28.

[0031] In addition, the start controller is used to control the working state of the cylinder 23. The roller 29 can move in this slide groove to realize the lifting and lowering movement of the support plate 24. A reinforcing plate is fixed between the upper and lower parallel beams of the bracket 25 to improve the overall rigidity of the bracket 25. The lower part of the bracket 25 is suspended and has no direct fixing point. This helps to reduce weight and improve flexibility without affecting its stability.

[0032] When the mast is in use, the operator needs to ensure that the forklift is in a stable state, and start the rotation function of the rotating assembly 1 through the forklift operation panel or a dedicated manual controller, and the turntable 12 will start to rotate by connecting to the rotation drive of the forklift body, thereby driving the entire mast assembly 2 to rotate;

[0033] Ensure that the goods have been correctly placed on the forks, and start the controller to control the extension and retraction of the cylinder 23, so as to realize the lifting and lowering of the bracket 25. When the cylinder 23 is extended, the force is transmitted to the bracket 25 through the connecting rod 28 to make it rise. When the cylinder 23 is retracted, the bracket 25 is lowered. The lifting and lowering action of the support plate 24 and the bracket 25 is realized by the roller 29 moving smoothly in the slide groove inside the gantry body 22;

[0034] If the position of the support arm 26 needs to be adjusted, first loosen the fastener, adjust the position of the support arm 26 as needed, and then re-fasten the fastener. The adjustment of the support arm 26 can adapt to cargoes of different sizes.

[0035] Through the above-mentioned structural setting and use method, the forklift revolving gantry can provide better operating flexibility in a small space, and is suitable for application scenarios that require frequent changes in direction or operations in limited spaces.

[0036] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make some simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
