[0001] This utility model specifically relates to the technical field of articulated boom lifting support components, and more specifically to an articulated boom lifting support component for processing large machinery. Background Technology
[0002] In the large machinery manufacturing industry, the hoisting and installation of large components are crucial links in the production process. With the development of modern industry, such as aerospace, shipbuilding, and large power generation equipment production, the machinery components involved are often characterized by their large weight, size, and complex shape. For example, in shipbuilding, a single component of a marine engine can weigh tens of tons, while in the production of large wind power equipment, wind turbine blades can be tens of meters long and weigh a considerable amount. These large machines require precise movement, flipping, and assembly operations in the processing workshop, and the performance of the support components of the folding boom crane, as a flexible and efficient hoisting device, is of paramount importance.
[0003] Traditional articulated boom crane support assemblies often suffer from insufficient stability when lifting ultra-large and ultra-heavy components. Due to limitations in their structural design and material selection, the support assembly may sway or tilt during lifting, especially when the boom extends a considerable distance or when lifting components close to its rated lifting capacity. This not only affects the accuracy of the lifting operation but also poses significant safety hazards. Summary of the Invention
[0004] The purpose of this utility model is to provide a folding arm lifting support assembly for large-scale machinery processing. By installing the lifting device and the support device, the folding arm lifting support assembly has excellent stability, thereby solving the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A folding arm lifting support assembly for large machinery processing includes
[0007] A support device, the upper end of which is connected to a hoisting device;
[0008] The support device includes a fixed base, with mounting holes at each of the four corners of the fixed base, and multiple clamping plates and columns installed at the upper end. The clamping plates are arranged in a ring at the bottom of the columns, and a sleeve is provided at the upper end of the columns. A fixed arc-shaped rod is provided on the outside of the sleeve, and the fixed arc-shaped rod is connected to the sleeve and the columns in an arc shape.

The upper end of the mounting plate 17 is also symmetrically provided with side plates 19. A clamping plate 110 is provided in the middle of the inner side of the side plate 19. The upper end of the clamping plate 110 is also inclined and an auxiliary lifting cylinder 111 is installed on the upper end.
[0029] Two rotating shafts 112 are installed on the upper end of the side plate 19, and the rotating shafts 112 are installed at one end of the main telescopic arm 21; the top ends of the main lifting cylinder 18 and the auxiliary lifting cylinder 111 are connected to the main telescopic arm 21.
[0030] By adopting the above technical solution, the sleeve 15 is fixed to the column 14 by the fixed arc rod 16. The arc shape of the fixed arc rod 16 improves the stability of the connection between the column 14 and the sleeve 15. The main lifting cylinder 18 and the auxiliary lifting cylinder 111 installed on the mounting plate 17 and the clamping plate 110 can adjust the rotation of the main telescopic arm 21 through the rotating shaft 112 on the side plate 19. The main lifting cylinder 18 and the auxiliary lifting cylinder 111 work together to improve the operating accuracy and also provide support for the hoisting device 2. When the hoisting device 2 tilts to a certain extent during hoisting, the main lifting cylinder 18 and the auxiliary lifting cylinder 111 can be adjusted to reduce the tilt of the hoisting device 2 and ensure hoisting safety.
[0031] In this embodiment, the upper surface of one end of the main telescopic arm 21 is provided with a mounting base 22. The mounting base 22 is fixedly connected to the upper end of the rope retraction seat 23. One end of the rope retraction seat 23 is equipped with a rotary motor 24, and the inner side is provided with a cable 25.
[0032] By adopting the above technical solution, the cable reel seat 23 installed on the upper surface of the main telescopic boom 21, through the rotary motor 24 installed at one end of the cable reel seat 23, reels and releases the cable 25. The rotary motor 24 controls the speed and tension of the cable 25. The cable 25 is connected to the hook 211 via the pulley 29. The pulley 29 is wrapped with rubber material, which can increase friction to prevent the cable 25 from slipping and protect the cable 25. The fixing hook 210 serves to fix the cable 25 and prevent the cable 25 from falling off the hoist during hoisting.
[0033] In this embodiment, an auxiliary telescopic cylinder 27 and a main telescopic cylinder 26 are respectively installed on the upper and lower surfaces of the main telescopic arm 21. The other ends of the main telescopic cylinder 26 and the auxiliary telescopic cylinder 27 are connected to the auxiliary telescopic arm 28. The main telescopic arm 21 and the auxiliary telescopic arm 28 are slidably connected through the main telescopic cylinder 26 and the auxiliary telescopic cylinder 27.

[0034] By adopting the above technical solution, the auxiliary telescopic cylinder 27 and the main telescopic cylinder 26 installed on the upper and lower surfaces of the main telescopic boom 21 allow the main telescopic cylinder 26 to adjust the telescopic length of the auxiliary telescopic boom 28. The auxiliary telescopic cylinder 27 can also coordinate the adjustment of the telescopic length of the auxiliary telescopic boom 28 and stabilize the hoist. In large machinery processing workshops, the layout of processing equipment and workpieces is often complex. After installing the main telescopic cylinder 26 and the auxiliary telescopic cylinder 27 on the main telescopic boom 21, the auxiliary telescopic boom 28 of the hoist can extend and retract flexibly. When it is necessary to hoist large machinery parts in a narrow working area, the main telescopic cylinder 26, the auxiliary telescopic cylinder 27, and the auxiliary telescopic boom 28 can cover a farther area, facilitating the hoisting operation of parts at a distance.
[0035] The working principle of this utility model is as follows: the sleeve 15 is fixed to the column 14 by the fixed arc rod 16. The arc shape of the fixed arc rod 16 improves the stability of the connection between the column 14 and the sleeve 15. The main lifting cylinder 18 and the auxiliary lifting cylinder 111 installed on the mounting plate 17 and the clamping plate 110 can adjust the rotation of the main telescopic arm 21 through the rotating shaft 112 on the side plate 19. The main lifting cylinder 18 and the auxiliary lifting cylinder 111 work together to improve the operating accuracy and also provide support for the hoisting device 2. When the hoisting device 2 tilts to a certain extent during hoisting, the main lifting cylinder 18 and the auxiliary lifting cylinder 111 can be adjusted to reduce the tilt of the hoisting device 2 and ensure hoisting safety.
[0036] The auxiliary telescopic cylinder 27 and the main telescopic cylinder 26 are installed on the upper and lower surfaces of the main telescopic boom 21. The telescopic length of the auxiliary telescopic boom 28 can be adjusted by the main telescopic cylinder 26. The auxiliary telescopic cylinder 27 can not only adjust the telescopic length of the auxiliary telescopic boom 28, but also stabilize the hoist. In large machinery processing workshops, the layout of processing equipment and workpieces is often complex. After the main telescopic boom 21 is equipped with the main telescopic cylinder 26 and the auxiliary telescopic cylinder 27, the auxiliary telescopic boom 28 of the hoist can extend and retract flexibly. When it is necessary to hoist large machinery parts in a narrow working area, the main telescopic cylinder 26, the auxiliary telescopic cylinder 27 and the auxiliary telescopic boom 28 can cover a farther area, making it convenient to hoist parts at a distance.
[0037] The main telescopic boom 21 has a rope reel seat 23 installed on its upper surface. The cable 25 is reeled in and out by a rotary motor 24 installed at one end of the rope reel seat 23. The rotary motor 24 controls the speed and tension of the cable 25. The cable 25 is connected to the hook 211 via a pulley 29. The pulley 29 is wrapped with rubber material, which increases friction to prevent the cable 25 from slipping and protects the cable 25. The fixing hook 210 fixes the cable 25 to prevent it from falling off the hoist during hoisting.
