Description

Technical Field

[0001] The present application belongs to the technical field of hoisting equipment, and specifically relates to a vehicle body electrophoresis 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 a water-based paint containing special resins and pigments. Under the action of the electric field, these particles will migrate in a directional manner and deposit on the surface of the car body to form a dense paint film, which is called the electrophoretic layer. When the electrophoretic layer of the car body is painted, it is necessary to use a lifting device to lift the car body, so that the car body is lowered into the electrophoretic pool for immersion and the car body is lifted from the electrophoretic pool. Since the lifting equipment needs to connect the pipeline containing the control circuit, etc., it is necessary to set up a collector for accommodating the pipeline. During the lowering and rising process of the lifting equipment, the pipeline in the collector will also bend. The greater the upward lifting amplitude of the lifting equipment, the greater the bending amplitude of the pipeline. If the bending degree of the pipeline is too large, the pipeline may be damaged due to excessive deformation. In addition, due to the large weight of the car body, the lifting equipment may shake during the lifting process, causing the collector to swing. If the collector swings during the collection process, it may cause the collector to twist and deform, resulting in failure to collect in place. Utility Model Content

[0003] The present application provides a vehicle body electrophoresis lifting device to solve at least one of the above-mentioned technical problems.

[0004] The technical solution adopted in this application is:

[0005] A vehicle body electrophoresis lifting equipment comprises a vehicle body lifting frame and a wire collector connected to the vehicle body lifting frame, wherein the wire collector can be extended as the vehicle body lifting frame is lowered and tightened as the vehicle body lifting frame is raised, wherein the wire collector comprises a plurality of adapter shafts and a plurality of connecting arms hinged by the adapter shafts for receiving pipelines, wherein the angle between two adjacent connecting arms increases as the wire collector is extended and decreases as the wire collector is tightened, and a limiting structure is provided between two adjacent connecting arms, and when the wire collector is gradually tightened until the angle between two adjacent connecting arms reaches a preset angle, the limiting structure can limit the continued tightening of the wire collector.

[0006] The vehicle body electrophoresis lifting equipment of the present application also includes the following additional technical features:

[0007] The limiting structure includes a stop rod and a stop groove respectively installed on two adjacent connecting arms. When the angle between the two adjacent connecting arms reaches a preset angle, the stop rod abuts against the stop groove.

[0008] The connecting arm comprises two limiting plates, both ends of which are respectively hinged to the switching shaft, and the projections of the two limiting plates of the same connecting arm on the vertical plane overlap.

[0009] The two ends of the stop rod are respectively connected to the two ends of the limit plate, and the limit plate is provided with a stop arc plate, and the stop arc plate is notched toward the direction of the stop rod adjacent thereto to form the stop groove.

[0010] There are multiple stop rods, and the multiple stop rods are arranged at intervals on the limiting piece.

[0011] The stop rod is connected to the connecting arm by welding.

[0012] The connecting arm is provided with a limit plate for limiting the escape of the pipeline at a position corresponding to the transfer shaft, and the extending direction of the limit plate is consistent with the ascending and descending direction of the vehicle body lifting frame.

[0013] The vehicle body lifting frame comprises a lifting frame located at the top and a plurality of lifting suspension rods, and a supporting portion for supporting the vehicle body is provided at the bottom end of each of the lifting suspension rods.

[0014] The supporting part is provided with a limiting piece for limiting the floating of the vehicle body.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0016] 1. The vehicle body electrophoretic lifting equipment of the present application includes a vehicle body lifting frame and a wire collector connected to the vehicle body lifting frame. The wire collector can be tightened and stretched synchronously with the rise and fall of the vehicle body lifting frame, thereby driving the pipelines carried in the adapter shaft to be tightened and relaxed synchronously, so that the pipelines move synchronously with the movement of the vehicle body lifting frame, providing storage space for the pipelines; wherein, a limiting structure is provided between two adjacent connecting arms, when the vehicle body lifting frame rises to a preset height and the angle between the two adjacent connecting arms reaches a preset angle, the limiting structure limits the continued tightening of the wire collector, thereby avoiding excessive tension of the pipeline and the occurrence of pipeline extrusion due to excessive tightening of the wire collector, providing a guarantee for the integrity of the pipeline and the working stability of the wire collector.

[0017] 2. As a preferred embodiment of the present application, the limiting structure includes a stop rod and a stop groove respectively installed on two adjacent connecting arms, and when the angle between the two adjacent connecting arms reaches a preset angle, the stop rod abuts against the stop groove. With such a configuration, the limiting of the wire collector can be completed only by the stopper cooperation between the stop rod and the stop groove, which simplifies the structural form of the limiting structure; at the same time, when the preset angle needs to be changed due to changes in the length of the pipeline or the size of the vehicle body, the size of the preset angle can be changed by setting different stop rods and stop groove sizes, thereby improving the adaptability of the wire collector.

[0018] 3. As a preferred embodiment of the present application, the connecting arm includes two limit plates, the two ends of the two limit plates are respectively hinged to the adapter shaft, and the projections of the two limit plates of the same connecting arm on the vertical plane overlap. The connecting arm is configured to be composed of two limit plates, so that the limit plates can play a certain shielding role for the pipelines carried between the two adapter shafts, reducing the volume of the pipelines exposed to the outside world; in addition, when assembling the connecting arm, it is only necessary to hinge the limit plates with the adapter shaft in turn, which simplifies the assembly process of the connecting arm and helps to improve the assembly efficiency of the wire collector.

[0019] 4. As a preferred embodiment of the present application, the two ends of the stop rod are respectively connected to the two ends of the limiting plate, and the limiting plate is provided with a stop arc plate, and the stop arc plate is notched toward the direction of the stop rod adjacent thereto to form the stop groove. Such a configuration enables the stop rod to further enhance the connection strength of the two limit plates, increase the connection tightness between the two limit plates, and thereby increase the structural strength of the connecting arm; in addition, when the wire collector is unevenly loaded due to unbalanced force or other reasons during the stretching and tightening process, the stop rod can also provide a stress transfer function to the two limit plates, thereby avoiding the possibility of stress concentration caused by the accumulation of stress on a single limit plate; that is, in addition to cooperating with the stop groove to provide a stopping function, the stop rod also integrates the function of enhancing the structural strength of the connecting arm and transferring the stress between the two limit plates. The functions are further integrated, thereby optimizing the structural design of the limit structure; furthermore, by setting a stop arc plate as a stop groove, it is avoided to open a groove on the limit plate as a stop groove, which helps to maintain the structural integrity of the limit plate and provides a guarantee for the structural strength of the limit plate.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, a vehicle body electrophoresis lifting equipment includes a vehicle body lifting frame 1 and a wire collector 2 connected to the vehicle body lifting frame 1, the wire collector 2 can be stretched as the vehicle body lifting frame 1 is lowered and tightened as the vehicle body lifting frame 1 is raised, the wire collector 2 includes a plurality of adapter shafts 21 and a plurality of connecting arms 22 for receiving pipelines hinged by the adapter shafts 21, the angle between two adjacent connecting arms 22 increases as the wire collector 2 is stretched and decreases as the wire collector 2 is tightened, a limiting structure is provided between two adjacent connecting arms 22, when the wire collector 2 is gradually tightened until the angle between the two adjacent connecting arms 22 reaches a preset angle, the limiting structure can limit the continued tightening of the wire collector 2.

[0037] The vehicle body electrophoretic lifting equipment of the present application includes a vehicle body lifting frame 1 and a wire collector 2 connected to the vehicle body lifting frame 1. The wire collector 2 can be tightened and stretched synchronously with the rise and fall of the vehicle body lifting frame 1, thereby driving the pipelines carried in the adapter shaft 21 to be tightened and relaxed synchronously, so that the pipelines move synchronously with the movement of the vehicle body lifting frame 1, providing storage space for the pipelines; wherein, a limiting structure is provided between two adjacent connecting arms 22, when the vehicle body lifting frame 1 rises to a preset height and the angle between the two adjacent connecting arms 22 reaches a preset angle, the limiting structure limits the continued tightening of the wire collector 2, thereby avoiding excessive tension of the pipeline and the occurrence of pipeline extrusion due to excessive tightening of the wire collector 2, and providing guarantees for the integrity of the pipeline and the working stability of the wire collector 2.

[0038] The preset angle referred to in the present application is not a fixed value, but a value that changes according to the aperture and number of the pipelines, to ensure that when the angle between two adjacent connecting arms 22 reaches the preset angle, the pipelines will not collide or be squeezed.

[0039] Specifically, as shown in the figure, the routing mode of the pipeline is to extend inside the connecting arm 22, and change the extension direction at the adapter shaft 21, and then continue to extend inside the connecting arm 22 after circling around the adapter shaft 21.

[0040] As a preferred embodiment of the present application, Figure 1 , Figure 2 As shown, as a preferred embodiment of the present application, the limiting structure includes a stop rod 3 and a stop groove 4 respectively installed on two adjacent connecting arms 22, and when the angle between the two adjacent connecting arms 22 reaches a preset angle, the stop rod 3 abuts against the stop groove 4. In this way, the limiting of the wire collector 2 can be completed only by the stopper cooperation of the stop rod 3 and the stop groove 4, which simplifies the structural form of the limiting structure; at the same time, when the preset angle needs to be changed due to changes in the length of the pipeline or the size of the vehicle body, the size of the preset angle can be changed by setting different sizes of the stop rod 3 and the stop groove 4, thereby improving the adaptability of the wire collector 2.

[0041] As a preferred embodiment of this implementation, Figure 1 , Figure 2As shown, the connecting arm 22 includes two limiting pieces 21, and the two ends of the two limiting pieces 21 are respectively hinged to the transfer shaft 21, and the projections of the two limiting pieces 21 of the same connecting arm 22 on the vertical plane overlap. The connecting arm 22 is configured to be composed of two limiting pieces 21, so that the limiting pieces 21 can play a certain shielding role for the pipelines carried between the two transfer shafts 21, reducing the volume of the pipelines exposed to the outside world; in addition, when assembling the connecting arm 22, it is only necessary to hinge the limiting pieces 21 with the transfer shaft 21 in turn, which simplifies the assembly process of the connecting arm 22 and helps to improve the assembly efficiency of the wire collector 2.

[0042] This embodiment does not limit the installation position and structural form of the stop rod 3 and the stop groove 4, and any one of the following examples may be adopted:

[0043] Example 1: The two ends of the stop rod 3 are respectively connected to the two ends of the limiting plate 21 , and a notch is provided on the limiting plate 21 , and the notch constitutes a stop groove 4 .

[0044] Example 2: The stop rod 3 is installed on one of the two limiting plates 21 , and a stop arc plate 5 is provided on the limiting plate 21 . The stop arc plate 5 is notched toward the adjacent stop rod 3 to form the stop groove 4 .

[0045] Example 3: Figure 1 , Figure 2 As shown, the two ends of the stop rod 3 are respectively connected to the two ends of the limiting plate 21 , and the limiting plate 21 is provided with a stop arc plate 5 , and the stop arc plate 5 is notched toward the stop rod 3 adjacent thereto to form the stop groove 4 . Such arrangement enables the stop rod 3 to further enhance the connection strength of the two limit plates 21, increase the connection tightness between the two limit plates 21, and thereby increase the structural strength of the connecting arm 22; in addition, when the wire collector 2 is unevenly loaded due to unbalanced force or other reasons during the stretching and tightening process, the stop rod 3 can also provide a stress transfer function for the two limit plates 21, thereby avoiding the possibility of stress concentration caused by the accumulation of stress on a single limit plate 21; that is, in addition to cooperating with the stop groove 4 to provide a stopping function, the stop rod 3 also integrates the functions of enhancing the structural strength of the connecting arm 22 and transferring the stress between the two limit plates 21, and the functions are further integrated, thereby optimizing the structural design of the limiting structure; furthermore, by providing a stop arc plate 5 as a stop groove 4, it is avoided to open a groove on the limit plate 21 as a stop groove 4, which helps to maintain the structural integrity of the limit plate 21 and provides a guarantee for the structural strength of the limit plate 21.

[0046] As a preferred example under this embodiment, Figure 1 , Figure 2As shown, there are multiple stop rods 3, and the multiple stop rods 3 are arranged at intervals on the limit plate 21. Such an arrangement can improve the connection stability of the limit plate 21, make the stress transfer between the two limit plates 21 more uniform, and further improve the structural strength of the connecting arm 22. Of course, this embodiment does not limit the number of stop rods 3. In another example, the number of stop rods 3 can also be set to one.

[0047] This embodiment does not limit the connection method between the stop rod 3 and the connecting arm 22, and it can adopt any one of the following embodiments:

[0048] Embodiment 1: The stop rod 3 is detachably connected to the connecting arm 22 .

[0049] Embodiment 2: The stop rod 3 and the connecting arm 22 are integrally formed.

[0050] Embodiment 3: The stop rod 3 and the connecting arm 22 are connected by welding.

[0051] As a preferred embodiment of the present application, Figure 2 As shown, the connecting arm 22 is provided with a limit plate 6 for limiting the escape of the pipeline at the position corresponding to the adapter shaft 21, and the extension direction of the limit plate 6 is consistent with the ascending and descending direction of the vehicle body lifting frame 1. Since the pipeline will be wound around the adapter shaft 21 at the adapter shaft 21 and deflected in the extension direction, when the vehicle body lifting frame 1 moves upward and the wire collector 2 is stretched, the pipeline will be relaxed accordingly, and the pipeline may be relaxed at the adapter shaft 21 and there will be a gap between the adapter shaft 21 and the adapter shaft 21. By providing the limit plate 6, the pipeline at the adapter shaft 21 can be shielded and protected, reducing the influence of external components on the pipeline.

[0052] As a preferred embodiment of the present application, Figure 1 As shown, the vehicle body lifting frame 1 includes a lifting frame 11 located at the top and a plurality of lifting rods 12, and a supporting portion 121 for supporting the vehicle body is provided at the bottom end of each lifting rod 12. Such a configuration enables the plurality of lifting rods 12 to jointly bear the weight of the vehicle body and the kinetic energy when the vehicle body is lifted or lowered, which helps to improve the lifting stability of the vehicle body.

[0053] As a preferred embodiment of this implementation, Figure 1 As shown, the support portion 121 is provided with a limiter 1211 for limiting the floating of the vehicle body. By providing the limiter 1211, it is possible to avoid the vehicle body from floating in the electrothermal tank due to its light weight, thereby ensuring the electroplating stability of the vehicle body in the electrothermal tank.

[0054] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0055] 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.

[0056] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
