Description

Technical Field

[0001] This utility model relates to the field of folding boom crane technology, and more specifically to an intelligent folding boom crane for all-round handling of lightweight objects. Background Technology

[0002] The boom of a knuckle boom crane features a foldable design, typically composed of multiple joints connected together, similar to a human arm. This design allows the boom to be retracted when not in operation, occupying minimal space and facilitating storage and transportation. Its omnidirectional handling capability enables the knuckle boom crane to quickly adapt to various complex working environments, such as handling materials at different heights and in different directions, meeting diverse production needs.

[0003] As shown in the prior art published in CN220684486U, although the prior art, through the setting of the limiting gear, enables the intelligent folding boom crane used for omnidirectional handling of light objects to have a large dynamic potential energy (i.e., large inertia) generated during rotation, which facilitates the limiting effect and achieves a good limiting effect and high safety, the limiting gear in this prior art cannot achieve omnidirectional rotational limiting. When the toothed block on the limiting gear rotates to correspond with the limiting frame, the limiting frame cannot engage with the gap on the limiting gear, so the limiting frame cannot effectively position the limiting gear. Therefore, this technical solution has certain limitations. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides an intelligent folding arm crane for omnidirectional handling of lightweight objects. It uses an energized electromagnetic ring to attract and fix an iron ring. Because the iron ring and the electromagnetic ring are always in contact, the electromagnetic ring can fix the iron ring at any rotation angle, thus achieving omnidirectional fixation of the iron ring. When the electromagnetic ring is de-energized and no longer attracts the iron ring, the iron ring is not restricted in its position and can be easily adjusted by rotating with the folding arm. This improves the convenience of limiting the position of the folding arm, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent folding arm crane for all-round handling of lightweight objects, including a folding arm for all-round handling of lightweight objects;

[0006] The folding arm is provided with a fastener on its exterior to enhance stability;

[0007] The fixing component includes an iron ring, with a fixed insulating shell and a movable insulating shell respectively fitted at the bottom and top of the iron ring. The fixed insulating shell is located at the bottom of the movable insulating shell, and an electromagnetic ring is installed inside the fixed insulating shell. The top of the electromagnetic ring is in contact with the bottom of the iron ring.

[0008] In a preferred embodiment, the folding arm includes a base, a mounting cylinder is rotatably connected to the top of the base, an adjusting shaft is movably connected to the mounting cylinder via a rotating shaft, an active frame is mounted on the top of the adjusting shaft, an auxiliary frame is rotatably connected to the top of the active frame, and a lifting arm is rotatably connected to the front end of the auxiliary frame.

[0009] The iron ring, the fixed insulating shell, and the movable insulating shell are all sleeved on the outside of the adjusting shaft, with the iron ring fixedly sleeved on the outside of the adjusting shaft, and the bottom end of the fixed insulating shell fixed together with the bottom of the inner cavity of the mounting cylinder.

[0010] In a preferred embodiment, a first motor for driving the adjustment shaft to rotate is installed on the outside of the top end of the mounting cylinder, a second motor for driving the auxiliary frame to rotate is installed on the outside of the top end of the active frame, and a third motor for driving the lifting arm to rotate is installed on the outside of the front end of the auxiliary frame.

[0011] In a preferred embodiment, air inlets are provided on both the front and rear sides of the bottom of the movable insulating shell, and a first dustproof net is installed inside the air inlets.

[0012] In a preferred embodiment, the top of the movable insulating shell is provided with an air outlet, and a fan and a second dustproof net are installed inside the air outlet, with the second dustproof net located on top of the fan.

[0013] In a preferred embodiment, fixed plates are installed on both the front and rear sides of the top of the fixed insulating shell, and movable plates are installed on one side of the front and rear ends of the movable insulating shell corresponding to the fixed plates, and the movable plates are fixed to the fixed plates by bolts.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] The iron ring is attracted and fixed by energizing the electromagnetic ring. Since the iron ring and the electromagnetic ring are always in contact, the electromagnetic ring can fix the iron ring at any rotation angle, thus achieving all-round fixation of the iron ring. When the electromagnetic ring is de-energized and does not attract the iron ring, the iron ring is not restricted and can be easily adjusted to rotate with the folding arm, thereby improving the convenience of limiting the folding arm.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figures 1-5 This utility model provides an intelligent folding boom crane for all-round handling of lightweight objects, including a folding boom for all-round handling of lightweight objects;

[0024] The folding arm includes a base 5, with a mounting cylinder 6 rotatably connected to the top of the base 5. An adjusting shaft 7 is movably connected to the mounting cylinder 6 via a rotating shaft. An active frame 8 is mounted on the top of the adjusting shaft 7, and an auxiliary frame 9 is rotatably connected to the top of the active frame 8. A lifting arm 10 is rotatably connected to the front end of the auxiliary frame 9. The iron ring 1, the fixed insulating shell 2, and the movable insulating shell 3 are all sleeved on the outside of the adjusting shaft 7, with the iron ring 1 fixedly sleeved on the outside of the adjusting shaft 7. The bottom end of the fixed insulating shell 2 is fixed to the bottom of the inner cavity of the mounting cylinder 6. A first motor 11 for driving the adjusting shaft 7 to rotate is mounted on the outside of the top of the mounting cylinder 6. A second motor 12 for driving the auxiliary frame 9 to rotate is mounted on the outside of the top of the active frame 8. A third motor 13 for driving the lifting arm 10 to rotate is mounted on the outside of the front end of the auxiliary frame 9.

[0025] In use, the first motor 11 drives the adjusting shaft 7 to rotate the active frame 8, and the second motor 12 drives the auxiliary frame 9 to rotate, thereby achieving the effect of adjusting the orientation of the lifting arm 10. Finally, the third motor 13 drives the lifting arm 10 to rotate, so that the lifting arm 10 can effectively grasp the object. Furthermore, the operation of the first motor 11, the second motor 12, and the third motor 13 can adjust the operating angle of the active frame 8, the auxiliary frame 9, and the lifting arm 10, which can effectively improve the handling effect and efficiency of this utility model.

[0026] like Figure 2 and 3 As shown, the outside of the folding arm is provided with a fixing component to enhance stability; the fixing component includes an iron ring 1, and a fixed insulating shell 2 and a movable insulating shell 3 are respectively fitted on the bottom and top of the iron ring 1. The fixed insulating shell 2 is located at the bottom of the movable insulating shell 3, and an electromagnetic ring 4 is installed inside the fixed insulating shell 2. The top of the electromagnetic ring 4 is in contact with the bottom of the iron ring 1.

[0027] In use, the operator powers on the electromagnetic ring 4, causing it to attract and fix the iron ring 1. This magnetic force secures the iron ring 1. Because the iron ring 1 and the electromagnetic ring 4 are always in contact, the electromagnetic ring 4 can fix the iron ring 1 at any rotation angle, thus achieving a 360-degree fixation effect. At the same time, the connection between the iron ring 1 and the adjusting shaft 7 allows the iron ring 1 and the adjusting shaft 7 to be fixed together, thus avoiding the risk of the folding arm tilting or falling due to pressure. When the electromagnetic ring 4 is de-energized and no longer attracts the iron ring 1, the iron ring 1 is not restricted in position and can be easily adjusted to rotate with the folding arm.

[0028] Meanwhile, to ensure the operational stability of electromagnetic ring 4, it is necessary to improve the heat dissipation effect of electromagnetic ring 4, such as... Figures 2-4 As shown, the movable insulating shell 3 has air inlets 14 on both the front and rear sides of its bottom end, and a first dustproof net 15 is installed inside the air inlets 14. The movable insulating shell 3 has an air outlet 16 on its top, and a fan 17 and a second dustproof net 18 are installed inside the air outlet 16. The second dustproof net 18 is located on top of the fan 17.

[0029] During use, the fan 17 draws external air into the movable housing through the air inlet 14, thereby promoting air circulation between the movable and fixed housings. The air circulation then dissipates the heat generated by the electromagnetic ring 4 during operation through the air outlet 16, thus preventing heat accumulation from affecting the performance of the electromagnetic ring 4 and ensuring the operational stability of the electromagnetic ring 4.

[0030] After using the above structure, it is necessary to regularly inspect and maintain equipment such as electromagnetic ring 4, for example... Figures 2-4As shown, fixed plates 19 are installed on both the front and rear sides of the top of the fixed insulating shell 2, and movable plates 20 are installed on both the front and rear ends of the movable insulating shell 3 on one side corresponding to the fixed plates 19, and the movable plates 20 are fixed to the fixed plates 19 by bolts.

[0031] Because the movable plate 20 and the fixed plate 19 are connected by bolts, the workers can remove the movable insulating shell 3 by unscrewing the bolts. At this time, the iron ring 1 and the electromagnetic ring 4 are not obstructed, which makes it convenient for the workers to inspect and maintain the electromagnetic ring 4 and the iron ring 1, and ensure the performance of the electromagnetic ring 4 and the iron ring 1.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
