[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0019] The following is for reference. Figures 1-5 The chassis line lifting device 10 according to an embodiment of this application is described. The chassis line lifting device 10 includes a lifting frame 11, lifting legs 12 and support components 13.
[0020] There are multiple lifting legs 12, which are located at the bottom of the spreader frame 11 and connected to it. The multiple lifting legs 12 are spaced apart along the length and width directions of the spreader frame 11. There are also multiple support assemblies 13, which are arranged one-to-one with the multiple lifting legs 12. Each support assembly 13 is located at the bottom of each lifting leg 12 and can selectively rotate relative to the lifting leg 12. Each support assembly 13 has a mounting portion 133 suitable for supporting the vehicle body.
[0021] Currently, in the chassis production line of the automobile prototyping workshop, the lifting equipment is a key piece of equipment for supporting and transporting the car body. The existing lifting points are fixed and cannot be moved flexibly along the Y-axis of the car body, so they can only be adapted to models with the same or very similar width. When faced with the production needs of models with different widths, the only options are to switch the existing lifting point positions or replace the entire lifting equipment. However, switching the lifting point positions is cumbersome and time-consuming, while replacing the lifting equipment is costly and can lead to production interruptions and reduced production efficiency.
[0022] In this regard, the present application proposes a chassis line hanger 10, which can achieve rapid compatibility with vehicles of different widths, ensuring ease of operation and operational stability.
[0023] Specifically, the chassis line lifting device 10 may include a lifting device frame 11, lifting legs 12, and a support assembly 13. There may be multiple lifting legs 12, which may be located at the bottom of the lifting device frame 11 and may be connected to the lifting device frame 11. Optionally, the lifting legs 12 and the lifting device frame 11 may be detachably connected by screws or bolts, or the lifting legs 12 and the lifting device frame 11 may be directly welded together by contact surfaces. The multiple lifting legs 12 may be spaced apart along the length and width of the lifting device frame 11. In some embodiments, there may be four lifting legs 12, which may be arranged in a square shape.
[0024] The number of support components 13 can be multiple, and multiple support components 13 can be set one-to-one with multiple hanger legs 12. Each support component 13 can be set at the bottom of each hanger leg 12, and each support component 13 can selectively rotate relative to the hanger leg 12. Each support component 13 has a mounting part 133, which can be used to support the car body. In the actual production process, the operator can adjust the support component 13 to rotate relative to the hanger leg 12, thereby changing the position of the mounting part 133, that is, the position of the car body mounting point. This setting can be compatible with car bodies of different widths, allowing car bodies of different widths to be produced on the chassis line without the need to replace the chassis line hanger 10. This achieves rapid compatibility with car bodies of different widths, reduces the overall cost, and avoids the problem of production interruption caused by changing the hanger, thus improving production efficiency. By setting multiple hanger legs 12, the stability of the car body supported on the chassis line hanger 10 can be improved.
[0025] In short, the chassis line hanger 10 of this application embodiment has hanger legs 12 and support components 13. There can be multiple hanger legs 12, which can be spaced apart at the bottom of the hanger frame 11 along the length and width directions. There can also be multiple support components 13, which can be arranged one-to-one with the multiple hanger legs 12. Each support component 13 forms a mounting part 133 suitable for carrying the vehicle body, and each support component 13 can selectively rotate relative to the hanger legs 12, thereby changing the position of the vehicle body mounting point. This allows the chassis line hanger 10 to be compatible with vehicles of different widths, enabling mixed production of vehicles of different widths on the chassis line, reducing overall costs, improving production efficiency, and ensuring ease of operation and operational stability.
[0026] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the support component 13 may include a support leg 131 and a trailing leg 132. The support leg 131 may be disposed at the bottom of the hanging leg 12 and may be selectively rotated relative to the hanging leg 12. The trailing leg 132 may be sleeved on the outer peripheral wall of the support leg 131 and may be selectively moved relative to the support leg 131. In some embodiments, the support leg 131 and the trailing leg are made of rectangular tubing with similar shapes. The inner dimension of the trailing leg is larger than the outer dimension of the support leg 131. Wear-resistant sliding strips that facilitate axial sliding are installed on the upper and lower flanges of the support leg 131. This structure ensures that the trailing leg slides flexibly relative to the support leg 131. Optionally, the trailing leg 132 can move along the extension direction of the support leg 131. The top of the trailing leg 132 can be provided with a mounting part 133. The trailing leg 132 can move relative to the support leg 131, which can further change the position of the vehicle body mounting point, thereby accommodating vehicles with different widths and enabling vehicles with different widths to be produced on the chassis line. In some embodiments, the outer peripheral wall of the support leg 131 can be formed with a first sliding part, and the inner wall of the trailing leg 132 can be formed with a second sliding part. The first sliding part can slide and cooperate with the second sliding part to ensure that the movement of the trailing leg 132 is more stable. Optionally, the first sliding part can be constructed as one of a slider and a groove, and the second sliding part can be constructed as the other of a slider and a groove. By using a slider to slide in the groove, the smoothness of the sliding of the trailing leg 132 can be further improved.
[0027] like Figure 2As shown, in some embodiments of this application, a mounting shaft 121 may be provided at the bottom of the support leg 12, and a sleeve 134 may be formed on the support leg 131. The sleeve 134 may be sleeved on the outer periphery of the mounting shaft 121, and the sleeve 134 may selectively rotate relative to the mounting shaft 121, thereby causing the support leg 131 to rotate relative to the support leg 12. Specifically, the sleeve 134 may rotate along the axis of the mounting shaft 121. By rotating the sleeve 134 along the mounting shaft 121, the mounting portion 13 can be changed. For example, during the production process, the sleeve 134 can rotate along the mounting shaft 121, causing the outrigger 131 to rotate around the hanging leg 12. The drag leg 132 can rotate synchronously with the outrigger 131. When the drag leg 132 moves to the bottom of the vehicle body, the position of the drag leg 132 is adjusted so that the mounting part 133 can cooperate with the vehicle body. When the chassis line hanger 10 moves the vehicle body to the working position, the drag leg 132 and the outrigger 131 can be restored, thereby removing the vehicle body from the chassis line hanger 10.
[0028] like Figure 2 and Figure 3 As shown, in some embodiments of this application, a first bearing 14 may be provided between the inner wall of the sleeve 134 and the mounting shaft 121. The inner ring of the first bearing 14 is tightly and fixedly connected to the mounting shaft 121, while the outer ring of the first bearing 14 is firmly connected to the inner wall of the sleeve 134, ensuring that the sleeve 134 can drive the outer ring to move synchronously when rotating. This arrangement allows the mounting shaft 121 and the sleeve 134 to rotate relatively flexibly, effectively reducing frictional resistance, reducing wear, improving the stability and reliability of the chassis line hanger 10, and extending its service life. In some embodiments, the first bearing 14 may be a deep groove ball bearing.
[0029] like Figure 2 and Figure 3 As shown, in some embodiments of this application, a second bearing 15 is provided between the inner wall of the sleeve 134 and the mounting shaft 121. The inner ring of the second bearing 15 can be fixedly connected to the bottom of the lifting leg 12, and the outer ring of the second bearing 15 can be provided at the top of the first bearing 14. This can ensure that when the sleeve 134 rotates relative to the mounting shaft 121, the frictional resistance between the sleeve 134 and the lifting leg 12 can be reduced, wear can be reduced, the stability and reliability of the chassis line lifting device 10 can be improved, and its service life can be extended. In some embodiments, the second bearing 15 can be a thrust ball bearing.
[0030] like Figure 2As shown, in some embodiments of this application, the bottom of the lifting leg 12 may be provided with a first extension 122, and the outer peripheral wall of the sleeve 134 may be provided with a second extension 1341. The first extension 122 and the second extension 1341 may be provided correspondingly in the height direction of the lifting frame 11. The chassis line lifting device 10 also includes a first locking member 16. The first locking member 16 may be provided on the first extension 122, and the first locking member 16 may be selectively locked or unlocked with the second extension 1341. When the first locking member 16 is locked with the second extension 1341, the relative fixation between the sleeve 134 and the lifting leg 12 can be achieved. When the first locking member 16 is unlocked from the second extension 1341, the sleeve 134 can rotate relative to the lifting leg 12, thereby changing the position of the mounting part 133.
[0031] In some embodiments, a first through hole may be formed on the first extension 122, and a second through hole may be formed on the second extension 1341. A first locking member 16 may be disposed on the first extension 122, and a portion of the first locking member 16 may pass through the first through hole. When the first locking member 16 passes through the second through hole, the first locking member 16 is locked to the second extension 1341. When the first locking member 16 disengages from the second through hole, the first locking member 16 is unlocked from the second extension 1341. The outer wall of the first locking member 16 may also be provided with a first elastic member, which can drive... The first locking member 16 is locked. It can be understood that when the sleeve 134 rotates to a certain position, the first elastic member can drive the first locking member 16 to move so that it passes through the second through hole and locks the first locking member 16 with the second extension 1341. By providing the first elastic member, the first locking member 16 can be prevented from disengaging from the second through hole, thereby improving the reliability of the first locking member 16. Optionally, the first locking member 16 can be a locking pin. In other embodiments, the first locking member 16 can abut against the second extension 1341 to lock the first locking member 16 with the second extension 1341.
[0032] like Figure 2 As shown, in some embodiments of this application, a clamping cover 135 may be provided at the bottom of the sleeve 134. The clamping cover 135 may be fixedly connected to the mounting shaft 121. The clamping cover 135 may clamp the sleeve 134 to prevent the sleeve 134 from falling due to gravity and ensure that the sleeve 134 can rotate along the mounting shaft 121. The reliability of the rotation of the sleeve 134 can be improved by providing the clamping cover 135.
[0033] like Figure 2As shown, in some embodiments of this application, a top cover 136 may be provided on the top of the sleeve 134. The top cover 136 can be sleeved on the lifting leg 12 and can be fixedly connected to the sleeve 134. The top cover 136 and the clamping cover 135 can be used to seal the cavity between the inner wall of the sleeve 134 and the mounting shaft 121. It should be noted that the cavity between the inner wall of the sleeve 134 and the mounting shaft 121 can be used to store grease. By providing the top cover 136 and the clamping cover 135, grease leakage can be prevented. The top cover 136 and the sleeve 134 can be detachably connected by screws or bolts, or the top cover 136 and the sleeve 134 can be detachably connected by snap-fit or plug-in. When there is not enough grease, the top cover 136 can be disassembled and grease can be added by using a syringe. After adding, the top cover 136 and the sleeve 134 can be fixed to complete the replenishment of grease.
[0034] like Figure 3 As shown, in some embodiments of this application, a movable cavity may be formed inside the drag leg 132, and at least a portion of the support leg 131 is movably disposed within the movable cavity. The chassis line hanger 10 may further include a second locking member 17, which may pass through the outer wall of the drag leg 132 and selectively lock or unlock the drag leg 132 and the support leg 131. Optionally, a third through hole may be formed on the support leg 131. When the second locking member 17 passes through the third through hole, the drag leg 132 and the support leg 131 are locked; when the second locking member 17 disengages from the third through hole, the drag leg 132 and the support leg 131 are unlocked. The outer wall of the second locking member 17 may also be provided with a second elastic member. The second elastic member can drive the second locking member 17 to lock. It can be understood that when the drag leg 132 moves to a certain position, the second elastic member can drive the second locking member 17 to move so that it passes through the third through hole and locks the drag leg 132 and the support leg 131. By providing the second elastic member, the second locking member 17 can be prevented from disengaging from the third through hole, thereby improving the reliability of the second locking member 17. Optionally, the second locking member 17 can be a locking pin. In other embodiments, the second locking member 17 can abut against the outer wall of the support leg 131 to lock the drag leg 132 and the support leg 131.
[0035] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments of this application, portions of two adjacent hanger legs 12 along the length direction extend away from each other. This arrangement allows the chassis line hanger 10 to be compatible with more vehicle models in the length direction and also reduces the space occupied by the hanger frame 11 in the length direction. Two adjacent hanger legs 12 along the width direction are connected by a reinforcing beam 18. The presence of a reinforcing beam 18 can further improve the structural strength of the hanger legs 12 and increase their service life.
