Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting equipment for a vehicle body longitudinal beam assembly. Background Technology

[0002] In the body shop of an automobile manufacturing plant, the clamping and transfer of longitudinal beams in the engine compartment is a crucial part of the production process. In the early days, due to limitations in funding and technology, many factories used manual lifting to move the longitudinal beams onto welding fixtures. This method was not only labor-intensive, which could easily lead to worker fatigue and injury, but it could also cause deformation and damage to parts due to improper operation, thereby affecting product quality and production efficiency, while also increasing the risk of safety accidents.

[0003] With the development of technology, transfer lifting tools have been gradually introduced, which has improved handling efficiency and safety to some extent. However, in recent years, major international automobile manufacturers and some domestic car companies have begun to use robots for the transfer and transportation of longitudinal beams in the engine compartment. Although robots can reduce labor intensity and improve production efficiency to a certain extent, their drawbacks have gradually become apparent when the production line changes models. Due to the differences in the structure and size of the longitudinal beams of different models, the grippers on the robot need to be changed according to the specific model. This adjustment process is time-consuming and requires a high level of technical skill from the operators. Utility Model Content

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In this specification, "multiple" refers to two or more.

[0021] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0022] Reference Figures 1-4 As shown, this utility model embodiment provides a vehicle body longitudinal beam assembly lifting device, including a crossbeam 1. Lifting rings 11 are fixedly connected to the upper ends of both the left and right sides of the crossbeam 1. A winch device 2 is provided at the upper right end of the crossbeam 1, used to lift the right end of the longitudinal beam. A hook mechanism 3 is provided at the lower left end of the crossbeam 1, and a connecting seat 4 is also provided at the lower end of the hook mechanism 3. A clamping mechanism 5 is provided at the lower end of the connecting seat 4, used to clamp and fix the left end of the longitudinal beam. During operation, the lifting rings 11 are connected to external lifting equipment, and the traction force of the winch device 2 is used to lift the right end of the longitudinal beam. At the same time, the hook mechanism 3 fixes the connecting seat 4, and the clamping mechanism 5 at the lower end of the connecting seat 4 clamps and fixes the left end of the longitudinal beam, ensuring the stability and reliability of the longitudinal beam during lifting, thereby achieving efficient and safe transfer of the longitudinal beam assembly.

[0023] In a further embodiment, refer to Figures 2-4The hook mechanism 3 includes a housing 31 and a hydraulic cylinder 32. The housing 31 is fixedly connected to the lower left end of the crossbeam 1, and the hydraulic cylinder 32 is fixedly connected inside the housing 31. The upper end of the hydraulic cylinder 32 extends through to the upper end of the crossbeam 1. The left and right ends inside the housing 31 are rotatably connected to a rotating shaft 33. The side wall of the rotating shaft 33 is fixedly connected to a hook 34. The two hooks 34 are symmetrical to each other. The side wall of the rotating shaft 33 is also fixedly connected to a stop block 35. The two stop blocks 35 are symmetrical to each other. The side wall of the output shaft of the hydraulic cylinder 32 abuts against the stop block 35. The included angle between the stop block 35 and the hook 34 is 90 degrees.

[0024] In this embodiment, the extension and retraction of the hydraulic cylinder 32 precisely pushes the abutment block 35. Since the angle between the abutment block 35 and the hook 34 is 90 degrees, the hook 34 can rotate stably and reliably around the shaft 33. When the output shaft of the hydraulic cylinder 32 extends outward, it pushes the abutment block 35 to rotate around the shaft 33, thereby pushing the hook 34 upward and causing the hook portion of the hook 34 to fit tightly against the left end of the longitudinal beam, thus firmly fixing the longitudinal beam. When the output shaft of the hydraulic cylinder 32 retracts, it releases the abutment from the hook 34. At this time, the hook 34 rotates in the opposite direction due to gravity, thereby releasing the longitudinal beam. This not only achieves rapid clamping and releasing of the longitudinal beam but also greatly improves the operating efficiency and reliability of the lifting device.

[0025] In a further embodiment, refer to Figures 2-3 The upper end face of the connecting seat 4 has a through hole 41, and the lower end face of the connecting seat 4 has a groove 42, which is connected to the through hole 41. The end of the groove 42 away from the through hole 41 has a mounting groove 43, and the inner wall of the groove 42 abuts against the upper end of the hook 34. The clamping mechanism 5 includes a clamping block 53 and a backing plate 55. The mounting grooves 43 on both sides of the connecting seat 4 are rotatably connected to a first connecting rod 51 and a second connecting rod 52. The first connecting rod 51 is away from the through hole 41. A pair of clamping blocks 53 are provided and are rotatably connected to the first connecting rod 55 through a bearing seat. At the lower end of the second connecting rod 52, a bushing 531 is fixedly connected to one of the adjacent ends of the two clamping blocks 53. The end of the second connecting rod 52 near the through hole 41 is rotatably connected to the third connecting rod 54 through the bearing seat. The abutment plate 55 is rotatably connected between the two third connecting rods 54 through the bearing seat. The third connecting rod 54 is located directly below the hydraulic cylinder 32. The lower ends of the left and right sides of the connecting seat 4 are fixedly connected to the connecting plate 6. The end of the connecting plate 6 near the through hole 41 is fixedly connected to the spring 61. The end of the spring 61 away from the connecting plate 6 is fixedly connected to the side wall of the first connecting rod 51.

[0026] In this embodiment, the carefully designed connecting seat 4 and clamping mechanism 5 enable quick changes in clamping methods and efficient and stable clamping of the left end of the vehicle body longitudinal beam. The through hole 41 on the connecting seat 4 is connected to the abutment groove 42 of the base, and the upper end of the hook 34 abuts against the abutment groove 42, ensuring that the hook 34 can be accurately positioned and securely fixed to the connecting seat 4. At the same time, the clamping mechanism 5, through the linkage of the first link 51, the second link 52 and the third link 54, causes the output shaft end of the hydraulic cylinder 32 to apply downward pressure to the abutment plate 55, so that the clamping block 53 can flexibly clamp the longitudinal beam. When the output shaft end of the hydraulic cylinder 32 releases the pressure on the abutment plate 55, the clamping block 53 releases the fixation of the longitudinal beam, and the setting of the liner 531 further enhances the firmness of the clamping and prevents the longitudinal beam from sliding or loosening during the hoisting process.

[0027] In addition, the design of spring 61 plays a crucial role in resetting. When the clamping mechanism 5 releases the longitudinal beam, spring 61, with its own elastic potential energy, drives the first connecting rod 51 connected to it to move, thereby driving the clamping block 53 to move back to the initial position. This ensures that the clamping block 53 can quickly and accurately return to the initial position after releasing the longitudinal beam, preparing for the next clamping operation. This improves the efficiency of the lifting device and the continuity of operation. At the same time, the elastic support of spring 61 can also provide a certain buffer during the clamping process, reducing the damage that may be caused to the longitudinal beam and clamping mechanism 5 by impact or vibration, further enhancing the stability and reliability of the lifting device.

[0028] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
