[0029] Currently, in a drying room, when the body parts are being transported by a conveyor chain while being baked, sometimes the beam carrying the body parts will deviate from the conveyor chain, making it impossible to continue the operation.

[0030] In view of the above technical problems, the present disclosure proposes a lifting device that can lift and adjust the position of vehicle body components.

[0031] For example, the above technical problems can be solved and the above technical effects can be achieved through the following embodiments.

[0032] Figure 1Detailed Description of the Invention It is a schematic perspective view showing some embodiments of the lifting device of the present disclosure. Figure 2 is a schematic front view showing some embodiments of the lifting device of the present disclosure. Figure 3 are schematic side views showing some embodiments of the lifting device of the present disclosure.

[0033] like Figure 1-Figure 3 As shown, the lifting device 1 is used to lift the body component, and the lifting device 1 includes: a support part 10, supporting the body component; a lifting mechanism 20, connected to the support part 10, configured to lift the support part 10; and a moving mechanism 30, arranged at the bottom of the lifting device 1, configured to be able to move to adjust the position of the body component.

[0034] In some embodiments, in order to bake the body parts while conveying them by the conveyor chain in the drying room, the body parts are supported on the crossbeam and placed on the conveyor chain. At this time, in some embodiments, the support part 10 has a shape that matches the bearing part that supports the body parts. It should be noted that the crossbeam is an example of the "bearing part" in the present disclosure. Figure 1-Figure 3 Not shown in the figure. Figure 1 , Figure 3 As shown, in some embodiments, the support portion 10 is composed of a groove-shaped member with a U-shaped cross section that is open upward. In this case, for example, a crossbeam carrying a body component is placed in the U-shaped groove of the support portion 10, thereby achieving support of the body component by the support portion 10. It should be noted that the shape of the support portion 10 is not particularly limited, and can be changed to match the shape of the support portion that carries the body component.

[0035] In some embodiments, the lifting mechanism 20 is a jack with a self-locking and pressure-maintaining function. When the support portion 10 supports the vehicle body component, the support portion 10 is lifted by the jack serving as the lifting mechanism 20. After being lifted to the desired height position, the lifting mechanism 20 is locked by the self-locking and pressure-maintaining function to lift and lock the vehicle body component at the desired height position. In this way, subsequent position adjustments to the vehicle body component can be made. It should be noted that the jack can be a mechanical jack such as a screw jack, a hydraulic jack, or other forms of jacks. Figure 1-Figure 3 2 shows an example in which the lifting mechanism 20 is a mechanical jack. In addition, the specific form of the lifting mechanism 20 is not limited to a jack, and any other form is also possible as long as the lifting of the support portion 10 can be achieved.

[0036] In some embodiments, Figure 1-Figure 3As shown, the moving mechanism 30 includes a plurality of universal wheels, which are disposed below a bottom plate 60 as a plate-like member. In this case, the lifting device 1 can easily adjust the position of the vehicle body component in any direction. Figure 1-Figure 3 In the figure, four universal wheels are shown, but the number of universal wheels is not limited and may be three, etc.

[0037] In some embodiments, Figure 1 , Figure 2 As shown, the lifting device 1 further includes a pull-down mechanism 40, which is connected to the support portion 10 and is configured to pull the support portion 10 downward. In this case, after the lifting device 1 is used to lift and adjust the position of the vehicle body component, that is, after the vehicle body component has been adjusted from the offset position to the specified position, the lifting of the support portion 10 by the lifting mechanism 20 is released. At this time, the pull-down mechanism 40 can pull the support portion 10 downward, so that the support portion 10 is separated from the cross beam supporting the vehicle body component, so that the lifting mechanism 20 is reset to the original position. By providing the lifting device 1 with the pull-down mechanism 40, it is possible to avoid the situation where the support portion 10 cannot be separated from the cross beam supporting the vehicle body component, resulting in the lifting mechanism 20 being unable to reset.

[0038] In some embodiments, Figure 1 , Figure 2 As shown, as a specific example, the pull-down mechanism 40 is composed of two springs arranged across the lifting mechanism 20, and the two springs are respectively arranged with one end arranged on the support portion 10 and the other end arranged on the bottom plate 60. It should be noted that the elastic coefficients of the two springs can be appropriately set according to actual use conditions.

[0039] In some embodiments, the lifting device 1 further includes an auxiliary support mechanism 50, which is retractably connected to the support portion 10, and is configured to assist the lifting mechanism 20 in lifting the support portion 10. In this case, when the lifting device 1 is used to lift the vehicle body component, the auxiliary support mechanism 50 is extended along with the lifting of the support portion 10. After the lifting and position adjustment of the vehicle body component is completed, the auxiliary support mechanism 50 is retracted along with the lowering of the support portion 10, thereby assisting the lifting mechanism 20 in lifting the support portion 10. By providing the lifting device 1 with the auxiliary support mechanism 50, the support portion 10 can be supported more stably, thereby more stably holding the vehicle body component, and avoiding accidental shaking, etc.

[0040] In some embodiments, Figure 1 , Figure 2As shown in the figure, as a specific example, the auxiliary support mechanism 50 includes two telescopic parts 50A and 50B arranged across the lifting mechanism 20, and the two telescopic parts 50A and 50B are respectively configured to have one end arranged on the support part 10 and the other end arranged on the bottom plate 60. It should be noted that the specific structure and the number of the two telescopic parts 50A and 50B are not particularly limited, as long as they can achieve the above-mentioned telescopic function and auxiliary support function. Figure 1 , Figure 2 2 shows a mode in which the two telescopic members 50A and 50B are telescopic tubes (telescopic rods).

[0041] The specific structures of some embodiments of the lifting device 1 of the present disclosure are described in detail above. Next, the process of lifting and adjusting the position of a vehicle body component by using the lifting device 1 of the present disclosure is described exemplarily.

[0042] When the crossbeam as the bearing part for bearing the body parts deviates on the conveying chain during the conveying process of the body parts, it is necessary to adjust the position of the crossbeam and the body parts so that the crossbeam and the body parts are reset to the normal conveying position. When the body parts are lifted and adjusted by the lifting device 1, first, the crossbeam bearing the body parts is placed on the support part 10, thereby realizing the support of the body parts by the support part 10. Then, the support part 10 supporting the crossbeam is lifted by the lifting mechanism 20. At this time, the auxiliary support mechanism 50 extends along with the lifting of the support part 10, and auxiliary support is provided to the support part 10 at multiple locations. After lifting to the desired height position (i.e., the height position that can be adjusted in the front, back, left and right directions), the lifting mechanism 20 is locked by the self-locking pressure-keeping function, and the support part 10 (body parts) is locked at the desired height position. Then, the moving mechanism 30 is used to move in any direction, thereby adjusting the position of the body parts. After the body parts have been reset to the specified position from the offset position, the lifting mechanism 20 is released to release the support and lifting of the support part 10. At this time, the pull-down mechanism 40 can pull the support portion 10 downward to separate the support portion 10 from the crossbeam supporting the vehicle body component, so that the lifting mechanism 20 is restored to the original position.

[0043] Above, the schematic structure of some embodiments of the lifting device 1 of the present invention has been appropriately described. The technical effects that can be achieved by the lifting device 1 of the present invention include but are not limited to: through the present invention, a lifting device that can lift and adjust the position of the body parts through a simple structure can be provided. According to the lifting device of the present invention, by the lifting mechanism being a jack with a self-locking and pressure-maintaining function, the stable lifting and support of the supporting part and thus the body parts can be achieved. In addition, according to the lifting device of the present invention, by having a moving mechanism, the position of the body parts can be easily adjusted in any direction. In addition, according to the lifting device of the present invention, by having a pull-down mechanism, the situation in which the supporting part cannot be detached from the crossbeam that supports the body parts and the lifting mechanism cannot be reset can be avoided. In addition, according to the lifting device of the present invention, by having an auxiliary support mechanism, the supporting part can be supported more stably, thereby more stably maintaining the body parts and avoiding accidental shaking, etc.

[0044] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims.
