[0002] Currently, lifting devices primarily serve the automotive manufacturing industry, demonstrating high efficiency and adaptability, especially in painting and mixed-line production. While their technical characteristics suggest the potential for expansion into high-end industries, their current applications remain concentrated in the automotive sector. Lifting devices mainly consist of a boom and a fulcrum, used in automotive conveyor systems to suspend car bodies, enabling stable suspension and safe transport of vehicles on the conveyor line.

[0003] Comparison of domestic and international technological levels:

[0004] Adaptability: Foreign rotatable boom spreaders typically have more advanced and reliable control systems and mechanical structures, meeting the lifting needs of many vehicle models. While domestic rotatable boom spreaders are continuously improving in this area, they still need to strive to catch up with advanced foreign technologies.

[0005] Stability: Foreign rotatable boom lifting devices utilize high-quality materials and advanced manufacturing processes in their design and production, ensuring long-term stable operation. Domestic rotatable boom lifting devices have also made significant improvements in stability, but there is still room for improvement in some key components and technologies.

[0006] Although the applicant's earlier application for the rotating sleeve rotation and locking method on the L-shaped boom (CN116873743A) can achieve the rotation of the entire boom, the locking structure between the fixed sleeve and the rotating sleeve is relatively complex and very inconvenient to use. Utility Model Content

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0025] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "side", "end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0026] Example 1

[0027] like Figure 1 The illustrated lifting device with a rotatable boom includes a rotating shaft 1 and a horizontal rotating arm 2 fixed to the bottom end of the rotating shaft 1. The horizontal rotating arm 2 extends horizontally, and an arc-shaped reinforcing plate 3 is provided between the horizontal rotating arm 2 and the rotating shaft 1 to ensure the connection strength between the two. A rotating arm switch assembly 6 is provided at the top end of the rotating shaft 1. A support assembly is fixed at the top end of the horizontal rotating arm 2 away from the rotating shaft 1. In this embodiment, the support assembly includes a fixing block 4 and a support column 5. The fixing block 4 is fixed to the horizontal rotating arm 2, and the support column 5 is fixed on the fixing block 4 and is perpendicular to the horizontal plane.

[0028] Specifically, in combination Figure 2 As shown, the rotary arm switch assembly includes a support block 602, a clamping plate 604, and a locking block 603. The support block 602 is fixed to the conveyor line by a base plate 601. The clamping plate 603 is fixed to one side of the outer wall of the support block 602. The top end of the rotating shaft 1 passes through the support block 602 and is fixed with the locking block 604. The rotating shaft 1 can move up and down along the support block 602. The locking block 604 is correspondingly arranged above the support block 602. The bottom end of the locking block 604 has a slot that can engage with the clamping plate 603.

[0029] Furthermore, the support block 602 is a cylindrical hollow structure with a through hole in the center for the rotating shaft 1 to pass through. The clamping plate 603 is detachably fixed to the outer wall of one side of the support block 602, and the top of the clamping plate 603 has a clamping block that extends upward and is higher than the top surface of the support block 602. The locking block 604 is also a cylindrical hollow structure with two slots at the bottom for the clamping block to be inserted. The two slots are set at 90 degrees along the circumference of the locking block 604. A pressure plate 605 is provided at the top of the locking block 604. The pressure plate 605 is fixed to the top of the rotating shaft 1 by a nut 606, thereby fixing the locking block 604 to the rotating shaft 1.

[0030] In use, when the vehicle body is detached from the lifting device, the rotating shaft 1 is raised by the power system or manually. The locking block of the clamping plate 603 disengages from one of the slots of the locking block 604, allowing the rotating shaft 1 to rotate 90 degrees so that its horizontal rotating arm 2 is parallel to the conveyor line. When the rotating shaft 1 falls, the locking block of the clamping plate 603 engages with the other slot of the locking block 604, preventing the rotating shaft 1 from rotating and achieving locking. By optimizing the design of the boom structure, it can achieve automatic rotation and positioning at multiple angles within a limited space, making full use of space, simplifying the structural design, and improving safety.
