Description

Technical Field

[0001] This utility model belongs to the field of automobile exhibition stand technology, and specifically relates to a lifting fixture for an automobile exhibition rotating stand. Background Technology

[0002] Currently, most automotive exhibition turntable lifting devices utilize hydraulic drive systems. A typical structure includes a base, hydraulic cylinders, a scissor brace mechanism, and a rotating platform. The hydraulic cylinders drive the scissor brace to raise and lower the platform, while the rotating platform is equipped with a drive motor to rotate the car. This architecture, thanks to the smoothness of hydraulic transmission and its large driving torque, meets the lifting and rotation requirements of the exhibition stand when carrying cars, and is widely used in the industry.

[0003] The hydraulic lifting device needs to provide continuous support when lifting the exhibition stand, and at the same time, it needs to withstand the dynamic load generated when the exhibition stand rotates with the car. This large combined load will accelerate the aging and wear of the hydraulic cylinder seals, causing poor sealing; in severe cases, it may even lead to structural damage such as piston rod bending, cylinder deformation, or internal wall scoring. Utility Model Content

[0004] To address the issue of heavy loads on hydraulic devices when lifting cars through an exhibition stand, this invention proposes a lifting fixture for a car exhibition turntable to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a lifting fixture for a car exhibition rotating platform, including an exhibition platform. The exhibition platform is equipped with a hydraulic lifting component inside. The lifting end of the hydraulic lifting component is equipped with a T-shaped exhibition platform. The T-shaped exhibition platform is equipped with a rotating exhibition component inside. The exhibition platform is equipped with a support component and a drive component inside. The support component and the drive component are poweredly connected. The hydraulic lifting assembly is used to move the T-shaped exhibition stand upward so that the rotating exhibition assembly is on the upper side of the exhibition stand, and the driving assembly is used to drive the support assembly to rotate so that the support assembly rotates to the bottom of the T-shaped exhibition stand.

[0006] Furthermore, the hydraulic lifting assembly includes a lifting channel, the T-shaped exhibition stand is fixedly connected to the lifting channel, and connecting frames are fixedly installed on the bottom of the inner wall of the exhibition stand and the bottom of the T-shaped exhibition stand. A scissor support frame is provided between the two connecting frames, and a hydraulic cylinder is provided inside the scissor support frame.

[0007] Furthermore, the rotating exhibition component includes a rotating groove, which is formed at the top of the T-shaped exhibition stand. A rotating platform is rotatably connected inside the rotating groove. Several casters are fixedly connected to the bottom of the rotating platform. The casters are in contact with the bottom of the inner wall of the rotating groove. A drive shaft is fixedly connected to the bottom of the rotating platform and passes through the T-shaped exhibition stand.

[0008] Furthermore, the T-shaped display stand has a storage cavity inside, and a driven gear is rotatably connected inside the storage cavity. The drive shaft is fixedly connected to the driven gear, and a driving gear meshes with the outer surface of the driven gear. A rotary motor is fixedly installed at the bottom of the T-shaped display stand, and the output end of the rotary motor is fixedly connected to the driving gear.

[0009] Furthermore, the support assembly includes support rods, several of which are provided at the bottom of the T-shaped display stand. Support rollers are fixedly connected to the top and bottom of each support rod. A connecting ring is provided inside the display stand, and all the support rods are fixedly connected to the connecting ring. Several through slots are provided at the bottom of the T-shaped display stand corresponding to the support rods.

[0010] Furthermore, the inner wall of the exhibition stand is fixedly connected to a guide rail, and the guide rail is movably connected to several guide rods, which are fixedly connected to their corresponding support rods.

[0011] Furthermore, the drive assembly includes an arc-shaped rack, which is fixedly installed on the top of two adjacent guide rods. A mounting frame is fixedly installed on the bottom of the inner wall of the exhibition stand. A drive gear is rotatably connected inside the mounting frame. The drive gear meshes with the arc-shaped rack. A drive motor is fixedly installed at the bottom of the mounting frame. The drive end of the drive motor is fixedly connected to the drive gear.

[0012] This utility model has the following beneficial effects: 1. This utility model drives a hydraulic lifting component, causing the T-shaped exhibition stand to lift the rotating exhibition component to a predetermined height. The driving component then drives a supporting component, allowing the supporting component to move to the bottom of the T-shaped exhibition stand. In this configuration, the supporting component supports the raised T-shaped exhibition stand, thus sharing the load on the hydraulic lifting component. This effectively prevents damage to the hydraulic lifting component due to large loads, thereby extending its service life.

[0013] 2. When the T-shaped display stand is raised by the hydraulic cylinder and scissor support frame, the T-shaped display stand can move outside the support rods through the through groove. When the T-shaped display stand rises to the predetermined height, the drive motor drives several support rods to rotate to the bottom of the T-shaped display stand through the drive gear, arc rack, guide rod and connecting ring. Thus, the support rods support the T-shaped display stand through the support rollers at both ends. When the T-shaped display stand is raised or lowered, the several support rods will not obstruct its raising or lowering path. At the same time, the several support rods only need to rotate a predetermined angle to complete the support of the T-shaped display stand. This setting realizes the quick switching between interference-free raising and lowering and full support, and the whole operation is relatively convenient.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0020] Please see Figures 1-9 As shown, this utility model is a lifting fixture for a car exhibition rotating platform, including an exhibition platform 1. The exhibition platform 1 is equipped with a hydraulic lifting component 2 inside. The lifting end of the hydraulic lifting component 2 is equipped with a T-shaped exhibition platform 3. The T-shaped exhibition platform 3 is equipped with a rotating exhibition component 4 inside. The exhibition platform 1 is equipped with a support component 5 and a drive component 6 inside. The support component 5 and the drive component 6 are poweredly connected. The hydraulic lifting assembly 2 is used to move the T-shaped exhibition stand 3 upward so that the rotating exhibition assembly 4 is on the upper side of the exhibition stand 1. The driving assembly 6 is used to drive the support assembly 5 to rotate so that the support assembly 5 rotates to the bottom of the T-shaped exhibition stand 3.

[0021] After the car is moved onto the rotating exhibition component 4, the hydraulic lifting component 2 is driven, which in turn moves the rotating exhibition component 4 upward through the T-shaped exhibition stand 3. Once it reaches the predetermined position, the driving component 6 drives the supporting component 5, which then moves the supporting component 5 to the bottom of the T-shaped exhibition stand 3.

[0022] By driving the hydraulic lifting component 2, the T-shaped booth 3 and rotating exhibition component 4 are raised to a predetermined height. Then, the driving component 6 drives the support component 5, allowing the support component 5 to move to the bottom of the T-shaped booth 3. In this configuration, the support component 5 can support the raised T-shaped booth 3, thus sharing the load on the hydraulic lifting component 2. This configuration can effectively prevent the hydraulic lifting component 2 from being damaged due to large loads, thereby extending the service life of the hydraulic lifting component 2.

[0023] In one embodiment, the hydraulic lifting assembly 2 includes a lifting groove 201, the T-shaped display stand 3 is fixedly connected to the lifting groove 201, and connecting frames 202 are fixedly installed on the bottom of the inner wall of the display stand 1 and the bottom of the T-shaped display stand 3. A scissor support frame 203 is provided between the two connecting frames 202, and a hydraulic cylinder 204 is provided inside the scissor support frame 203.

[0024] The scissor support frame 203 has its upper and lower ends rotatably connected to the corresponding connecting frame 202 on one side. On the other side, both upper and lower ends of the scissor support frame 203 are rotatably connected to rotating wheels, which are also connected to the corresponding connecting frame 202. Simultaneously, the bottom end of the hydraulic cylinder 204 is rotatably connected to the lower connecting frame 202, while the output end of the hydraulic cylinder 204 is rotatably connected to the scissor support frame 203. During lifting, the hydraulic cylinder 204 pushes the scissor support frame 203, causing it to retract. The retracted scissor support frame 203 then lifts the T-shaped display stand 3 via the connecting frame 202, allowing the T-shaped display stand 3 to rise to the upper side of the display stand 1 via the lifting groove 201. When the outwardly protruding part of the T-shaped display stand 3 contacts the top of the inner wall of the display stand 1, the driving of the hydraulic cylinder 204 stops.

[0025] In one embodiment, the rotating exhibition component 4 includes a rotating groove 401, which is located on the top of the T-shaped exhibition stand 3. A rotating platform 402 is rotatably connected inside the rotating groove 401. Several casters 403 are fixedly connected to the bottom of the rotating platform 402. The casters 403 are in contact with the bottom of the inner wall of the rotating groove 401. A drive shaft 404 is fixedly connected to the bottom of the rotating platform 402 and passes through the T-shaped exhibition stand 3.

[0026] Several casters 403 can support the rotary table 402. When the rotary table 402 is driven to rotate inside the rotating groove 401 by the drive shaft 404, the casters 403 can roll at the bottom of the inner wall of the rotating groove 401. The above arrangement makes the rotary table 402 rotate more smoothly, and the load on the drive source used to drive the drive shaft 404 is smaller.

[0027] In one embodiment, for the T-shaped display stand 3, the interior of the T-shaped display stand 3 is provided with a storage cavity 405, a driven gear 406 is rotatably connected inside the storage cavity 405, the drive shaft 404 is fixedly connected to the driven gear 406, the outer surface of the driven gear 406 is meshed with a driving gear 407, a rotary motor 408 is fixedly installed at the bottom of the T-shaped display stand 3, and the output end of the rotary motor 408 is fixedly connected to the driving gear 407.

[0028] By driving the rotary motor 408, the rotary motor 408 drives the drive gear 407 to rotate inside the receiving cavity 405. At this time, the rotating drive gear 407 can drive the drive shaft 404 to rotate through the driven gear 406.

[0029] In one embodiment, the support component 5 includes a support rod 501. Several support rods 501 are provided at the bottom of the T-shaped display stand 3. Support rollers 502 are fixedly connected to the top and bottom of the support rods 501. A connecting ring 503 is provided inside the display stand 1. All the support rods 501 are fixedly connected to the connecting ring 503. Several through slots 504 are opened at the bottom of the T-shaped display stand 3 corresponding to the support rods 501.

[0030] The support rollers 502 at the bottom of the support rods 501 are in contact with the bottom of the inner wall of the exhibition stand 1. When the T-shaped exhibition stand 3 is stored inside the exhibition stand 1, the support rods 501 are located inside the corresponding through slots 504. When the T-shaped exhibition stand 3 is raised to a predetermined height, the support rods 501 are rotated through the connecting ring 503, so that the support rollers 502 at the top of the support rods 501 are in contact with the top of the T-shaped exhibition stand 3. At this time, the support rods 501 can support the T-shaped exhibition stand 3 through the support rollers 502 at both ends. The through slots 504 ensure that the support rods 501 do not obstruct the raising and lowering of the T-shaped exhibition stand 3. At the same time, when supporting the T-shaped exhibition stand 3, it is only necessary to rotate the connecting ring 503 by a certain angle, which is also convenient.

[0031] In one embodiment, for the exhibition stand 1, the inner wall of the exhibition stand 1 is fixedly connected to a guide rail 505, and the guide rail 505 is movably connected to a plurality of guide rods 506, and the guide rods 506 are fixedly connected to the corresponding support rods 501.

[0032] When the connecting ring 503 drives the several support rods 501 to rotate, the guide rod 506 can slide inside the guide rail 505. In the above configuration, the guide rail 505 can guide the connecting ring 503 through the guide rod 506 and the support rods 501, so that the connecting ring 503 and the axis of the exhibition stand 1 always remain collinear, and at the same time, the stability of the several support rods 501 when supporting the T-shaped exhibition stand 3 can be guaranteed.

[0033] In one embodiment, the drive assembly 6 includes an arc-shaped rack 601, which is fixedly mounted on the top of two adjacent guide rods 506. A mounting bracket 602 is fixedly mounted on the bottom of the inner wall of the exhibition stand 1. A drive gear 603 is rotatably connected inside the mounting bracket 602. The drive gear 603 meshes with the arc-shaped rack 601. A drive motor 604 is fixedly mounted on the bottom of the mounting bracket 602. The drive end of the drive motor 604 is fixedly connected to the drive gear 603.

[0034] By driving the drive motor 604, the drive motor 604 drives the arc rack 601 to rotate through the drive gear 603. Since the axis of the arc rack 601 is coaxial and collinear with the connecting ring 503, the arc gear 506 can drive the connecting ring 503 to rotate through the guide rod 506, and allow several support rods 501 to rotate to the bottom of the T-shaped display stand 3.

[0035] Through the above technical solution, 1. By driving the hydraulic lifting component 2, and causing the T-shaped booth 3 to lift the rotating exhibition component 4 to a predetermined height, the driving component 6 drives the supporting component 5, thereby allowing the supporting component 5 to move to the bottom of the T-shaped booth 3; in the above setting, the supporting component 5 can support the T-shaped booth 3 after it has been raised, thereby allowing the supporting component 5 to share the load on the hydraulic lifting component 2. This setting can effectively prevent the hydraulic lifting component 2 from being damaged due to large loads, thereby improving the service life of the hydraulic lifting component 2; 2. When the T-shaped booth 3 is raised by the hydraulic cylinder 204 and the scissor support frame 203, the T-shaped booth... 3. The support rod 501 can be moved outside through the through slot 504. When the T-shaped booth 3 rises to the predetermined height, the drive motor 604 drives the support rods 501 to rotate to the bottom of the T-shaped booth 3 through the drive gear 603, the arc rack 601, the guide rod 506 and the connecting ring 503. Thus, the support rods 501 support the T-shaped booth 3 through the support rollers 502 at both ends. When the T-shaped booth 3 is raised or lowered, the support rods 501 will not obstruct its raising or lowering path. At the same time, the support rods 501 only need to rotate a predetermined angle to support the T-shaped booth 3. This setting realizes the quick switching between interference-free raising and lowering and in-position support, and the whole operation is relatively convenient.
