Description

Technical Field

[0001] The present application belongs to the technical field of hoisting equipment, and in particular relates to a vehicle body hoisting structure applied to electrophoretic hoisting equipment. Background Art

[0002] In the automobile production process, electrophoretic coating is an important production stage. The car body needs to be immersed in water-based paint containing special resins and pigments. The area where these water-based paints are loaded is called the electrophoretic pool. Under the action of the electric field, these particles will migrate and deposit on the surface of the car body to form a dense paint film, which is called the electrophoretic layer. When painting the electrophoretic layer of the car body, it is necessary to use lifting equipment to lift the car body, so that the car body can be lowered into the electrophoretic pool for immersion and lifted out of the electrophoretic pool.

[0003] The lifting equipment includes a body lifting frame and a lifting structure under the body lifting frame. Since the body shapes are various, it is necessary to set a lifting structure suitable for the body of different structural types to achieve stable support for the body. Moreover, since the density of the water-based paint in the electroplating tank is relatively high, the body may float when it is electroplated in the electroplating tank, thereby affecting the stability of the body lifting. In order to limit the floating of the body under the buoyancy of the water-based paint, a limiter is usually provided on the lifting structure. The limiter is inserted into a through hole or mounting groove in the body to limit the floating of the body. However, the body structure is various, and the positions of the through holes or mounting grooves on the body are also different. Therefore, it is necessary to replace the lifting structure with a limiter suitable for different body. The replacement of the lifting structure is difficult, which affects the coating efficiency.

[0012] Two upper limit rings and a lower limit ring are arranged at intervals on the hoisting rod, and the upper limit ring and the lower limit ring are respectively in contact with the top of the rotating mechanism and the bottom of the rotating mechanism.

[0035] like Figures 1 to 3 As shown, a vehicle body lifting structure applied to electrophoretic lifting equipment is installed on a vehicle body lifting frame 1, including a lifting unit and a vehicle body supporting unit 3 installed at the lower end of the lifting unit, the lifting unit including a lifting rod 2 with one end connected to the vehicle body lifting frame 1 and the other end extending downward in a vertical direction, the vehicle body supporting unit 3 including a supporting portion 31 and a rotating mechanism 32 for rotatably connecting the supporting portion 31 with the lifting rod 2, the supporting portion 31 can be rotated around the lifting rod 2 by the rotating mechanism 32 so as to have a plurality of supporting positions, one of the rotating mechanism 32 and the lifting rod 2 is provided with a limit member 4, and the other is provided with a matching member 5, the limit member 4 can move relative to the matching member 5 to have a locking position abutting against the matching member 5 to limit the rotation of the rotating mechanism 32 and a free position separated from the matching member 5 to release the rotation restriction of the rotating mechanism 32.

[0036] The vehicle body lifting structure of the present application is provided with a vehicle body supporting unit 3 at the lower end of the lifting unit for supporting the vehicle body to ensure that the vehicle body remains stable during the lifting and lowering process, and is provided with a rotating mechanism 32, through which the supporting portion 31 is rotatably connected to the lifting rod 2, so that the supporting portion 31 can be rotated around the lifting rod 2 through the rotating mechanism 32 to have multiple supporting positions. For vehicle bodies with different structures, it is only necessary to adjust the position of the supporting portion 31 through the rotating mechanism 32, and adjust the supporting portion 31 to a supporting position suitable for the vehicle body, so as to achieve stable support for the vehicle body, thereby improving the adaptability of the vehicle body lifting structure to different vehicle bodies and reducing the frequency of replacing the vehicle body lifting structure when electrophoretic coating is performed on different vehicle bodies. When performing continuous electrophoretic coating, it helps to improve the efficiency of electrophoretic coating; in addition, a limit member 4 and a matching member 5 are respectively provided on the rotating mechanism 32 and the lifting rod 2. The locking and loosening of the rotation of the rotating mechanism 32 are achieved by switching the limit member 4 between the locking position and the free position. When it is necessary to adjust the position of the supporting part 31, the limit member 4 is adjusted to the free position. At this time, the rotating mechanism 32 can rotate freely to adjust the supporting part 31 to move to a suitable supporting position; when the position of the supporting part 31 is adjusted, the limit member 4 is adjusted to the locking position to limit the rotation of the rotating mechanism 32, thereby achieving a stable connection between the supporting part 31 and the lifting rod 2, so that the supporting part 31 can be stably placed in the supporting position, ensuring that the body supporting unit 3 stably supports the body.

[0037] The present application does not limit the arrangement positions of the limiting member 4 and the matching member 5, and any of the following embodiments may be adopted:

[0038] Embodiment 1: The limiting member is arranged on the rotating mechanism, and the matching member is arranged on the hanging rod.

[0039] Implementation method 2: Figure 2 As shown, the limiting member 4 is arranged on the hanging rod 2 , and the matching member 5 is arranged on the rotating mechanism 32 .

[0040] As a preferred embodiment of the second implementation mode, Figure 2 As shown, the matching member 5 is provided with a plurality of limiting slots 51 at intervals on the rotation path of the rotating mechanism 32. When the limiting member 4 is in the locking position, the limiting member 4 is inserted into the limiting slot 51 and abuts against the inner wall of the limiting slot 51. By providing a plurality of limiting slots 51, the limiting member 4 has a plurality of locking positions equal to the number of limiting slots 51, and at the same time, the number of supporting positions that the supporting portion 31 can have is increased, that is, the adaptability of the supporting portion 31 to vehicle bodies with different structures is improved.

[0041] As a preferred example under this embodiment, Figure 2As shown, the lifting rod 2 is provided with an outer protrusion 21 with a limiting through hole, the limiting member 4 has a limiting section 41 extending in the vertical direction and a bending section 42 forming an angle with the limiting section 41, the limiting section 41 can be plugged into the limiting through groove 51, and the limiting member 4 is mounted on the outer protrusion 21 through the bending section 42. When the limiting member 4 is in the locking position, the projections of the limiting through hole and the limiting through groove 51 on the horizontal plane both cover the limiting section 41. With such arrangement, when it is necessary to adjust the position of the supporting portion 31, the limiting section 41 can be pulled out from the limiting through slot 51 to switch the limiting member 4 to the free position. At this time, the rotating mechanism 32 can be freely rotated and the position of the supporting portion 31 can be adjusted; when the position of the supporting portion 31 is adjusted, the limiting section 41 can be inserted into the limiting through hole, thereby driving the limiting member 4 to switch to the locked position. At this time, the limiting member 4 will not slide in the vertical direction under the cooperation of the bending section 42 and the outer protrusion 21, thereby eliminating the need for a separate operation for fixing the limiting member 4 in the locked position, thereby optimizing the structural design of the limiting member 4.

[0042] As a preferred embodiment of the present application, Figure 3 As shown, the rotating mechanism 32 has a rotating groove 6 adapted to the hanging rod 2, and the rotating mechanism 32 is sleeved on the hanging rod 2 through the rotating groove 6. In this way, when the rotating mechanism 32 rotates around the hanging rod 2, the rotating mechanism 32 and the hanging rod 2 share the space of the projection part of the rotating groove 6 on the horizontal plane, which reduces the space required to be occupied by the rotating mechanism 32 during the rotation process, and contributes to the miniaturization of the vehicle body hanging structure.

[0043] As a preferred embodiment of the present application, Figure 1 , Figure 2 As shown, two upper limit rings 22 and lower limit rings 23 are arranged at intervals on the hoisting rod 2, and the upper limit ring 22 and the lower limit ring 23 are respectively in contact with the top of the rotating mechanism 32 and the bottom of the rotating mechanism 32. In this way, the rotating mechanism 32 is stably placed between the upper limit ring 22 and the lower limit ring 23, which reduces the possibility of the rotating mechanism 32 being vertically offset during the rotation process, and provides a guarantee for the rotation stability of the rotating mechanism 32; in addition, the arrangement of the upper limit ring 22 and the lower limit ring 23 provides a sliding surface for the rotating mechanism 32 during the rotation process, which helps to improve the smoothness of the rotation of the rotating mechanism 32.

[0044] As a preferred embodiment of the present application, Figure 3As shown, the vehicle body supporting unit 3 also includes a vehicle body limiting assembly 7 installed on the supporting part 31, one end of the supporting part 31 is connected to the lifting rod 2, and the other end extends horizontally in a horizontal direction away from the rotating mechanism 32 and has a supporting surface 311 for supporting the vehicle body, and the vehicle body limiting assembly 7 includes a positioning boss 71 arranged on the top of the supporting surface 311. Since the bottom of the vehicle body frame usually has multiple horizontal surfaces, the supporting part 31 is set to have one end connected to the lifting rod 2 and the other end extending away from the lifting rod 2 to form a supporting surface 311 for supporting the vehicle body, which helps to improve the compatibility of the supporting part 31 and the vehicle body and makes the vehicle body placed on the supporting surface 311 more stable; in addition, since the density of the water-based paint in the electrothermal pool is relatively large, it is easy to cause the vehicle body to float. By setting a vehicle body limiting assembly 7 including a positioning boss 71, when the vehicle body is hoisted on the vehicle body hoisting structure, the positioning boss 71 can be inserted into a process groove on the vehicle body or a separately opened positioning hole, etc., which can limit the lateral displacement of the vehicle body on the one hand, and prevent the vehicle body from shaking in the horizontal direction under the buoyancy and fluctuation of the water-based paint, thereby improving the hoisting stability of the vehicle body; on the other hand, when the vehicle body is hoisted onto the vehicle body hoisting structure, the insertion and cooperation of the positioning boss 71 with the positioning hole or process groove on the vehicle body helps to achieve rough positioning of the vehicle body hoisting, eliminating the operator's operation of accurately calibrating the position of the vehicle body, which helps to improve the hoisting efficiency of the vehicle body.

[0045] As a preferred embodiment of this implementation, Figure 3 As shown, the positioning boss 71 is provided with a laterally extending limit socket, and the vehicle body limit assembly 7 also includes a positioning latch 72, the positioning latch 72 includes two plug rods 721 extending in the horizontal direction and a connecting section 722 connecting the two plug rods 721, one of the two plug rods 721 is inserted into the limit socket, and the other is inserted into the positioning hole of the vehicle body structure. Specifically, when the vehicle body is placed on the vehicle body lifting structure, the positioning boss 71 is inserted into the interior of the vehicle body, and then the positioning latch 72 is inserted into the vehicle body laterally to limit the vertical movement of the vehicle body, which helps to reduce the possibility of shaking of the vehicle body during lifting or lowering, thereby improving the stability of the lifting process; in addition, during the electrophoretic coating process, the positioning latch 72 can also limit the floating of the vehicle body under the buoyancy of the water-based paint, thereby further improving the stability of the vehicle body electrophoretic coating process and helping to improve the coating effect; furthermore, the positioning boss 71 under the present embodiment, on the basis of playing the role of roughly positioning the vehicle body and limiting the lateral displacement of the vehicle body, further integrates the function of fixing the positioning latch 72, eliminating the operation of separately setting up the positioning latch 72, and further integrating the functions, thereby optimizing the structural design of the vehicle body limiting assembly 7.

[0046] As another preferred embodiment of this implementation mode, Figure 3 As shown, the vehicle body limiting assembly 7 further includes a limiting hook 73, which is connected to the supporting portion 31 through a chain, and can be hooked to the vehicle body structure to limit the floating of the vehicle body structure. The limiting hook 73 can limit the vertical displacement of the vehicle body, reduce the possibility of the vehicle body floating due to the influence of water-based paint during the electrophoretic coating process, improve the stability of the vehicle body electrophoretic coating process, and help improve the coating effect.

[0047] As a preferred embodiment of the present application, the number of the hoisting units is multiple. Setting the number of hoisting units to multiple helps to improve the stability of the vehicle body hoisting and reduce the possibility of shaking of the vehicle body during the hoisting process and the electrophoretic coating process.

[0049] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
