Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, and in particular to a vehicle body side panel transfer trolley. Background Technology

[0002] In the vehicle side panel stamping workshop, when production conditions change, according to engineering quality management regulations, samples of initial, intermediate, and final products need to be retained for inspection. Vehicle side panel components (hereinafter referred to as "panels") need to be transported to the testing area before quality inspection. Currently, the transfer process is carried out using trolleys. Panels from different production stages are stacked on the trolleys and then transferred to the testing area. When using this transfer method, if a lower panel needs to be inspected, the upper panel needs to be manually removed. After the panel to be inspected is removed, the upper panel is moved back to its original position. Due to the significant weight of the panels, this process consumes a lot of time, and repeated movement of the panels can easily cause collisions between them, thus affecting the quality inspection results.

[0003] In view of this, the present invention proposes a vehicle body side panel transfer trolley to solve or alleviate the above-mentioned technical problems. Utility Model Content

[0006] Chassis frame;

[0007] Multiple wheels are installed at intervals on the chassis frame to support the movement of the chassis frame;

[0008] A support frame, the support frame including a support crossbar and at least two support columns, the at least two support columns being installed at intervals on the side of the chassis frame away from the traveling wheels, and the support columns being perpendicular to the top surface of the chassis frame, the support crossbar being installed on the support columns, and the support crossbar being parallel to the length direction of the chassis frame;

[0009] Two sets of hanging plate assemblies are installed at intervals on the support crossbar. Each hanging plate assembly includes a hanging rod and a connector. The hanging rod is installed on the connector, and the connector is clamped on the support crossbar. The hanging rod is perpendicular to the support crossbar, and the distance between the two ends of the hanging rod and the support crossbar is equal.

[0010] In one embodiment, the connector includes a bolt and two clamping plates arranged in parallel. The bolt passes through the two clamping plates, and the hanging rod is connected to both clamping plates simultaneously. The hanging rod, the bolt, and the two clamping plates enclose a clamping space, and the supporting crossbar passes through the clamping space. The bolt is used to clamp the two clamping plates to the supporting crossbar.

[0011] In one embodiment, the hanging rod includes a main rod and two sub-rods. The main rod is perpendicular to the supporting crossbar and is simultaneously connected to the two clamping plates. The main rod has a sliding cavity, and the sub-rods are movably installed in the sliding cavity. The two sub-rods can extend from both ends of the main rod, respectively.

[0012] In one embodiment, the hanging rod further includes an external threaded knob handle, which includes a handle and a screw mounted on the handle. The side wall of the female rod has a threaded hole, and the screw extends through the threaded hole into the sliding cavity. The end of the screw away from the handle can abut against the side wall of the male rod.

[0013] In one embodiment, the hanging rod further includes a hook, which is installed on the end of the sub-rod that extends out of the main rod.

[0014] In one embodiment, the hanging rod further includes a buffer layer, which is fitted onto the end of the sub-rod extending from the mother rod and the surface of the hook.

[0015] In one embodiment, the vehicle body side panel transfer trolley further includes a enclosure structure, the enclosure structure including multiple protective doors and two brackets, and the two brackets are respectively installed at both ends of the chassis frame along the length direction of the chassis frame;

[0016] Along a direction perpendicular to the length direction, each of the brackets is rotatably mounted on both sides of the protective door, which has an open state and a closed state;

[0017] When the protective door is in the open state, the protective door is perpendicular to the length direction;

[0018] When the protective door is in the closed state, the protective door is parallel to the length direction and is connected to the chassis frame pin.

[0019] In one embodiment, the support includes a first protective net and at least two uprights, the uprights being vertically installed on the chassis frame, and the first protective net being installed between adjacent uprights;

[0020] The protective door includes a gantry and a second protective net. The gantry is rotatably mounted on the bracket, and the second protective net is mounted on the gantry.

[0021] In one embodiment, the vehicle body side panel transfer trolley further includes a jacking device, which is mounted on the chassis frame and is located on the same side as the traveling wheels.

[0022] In one embodiment, the support frame further includes reinforcing ribs, which are connected to the side wall of the support column and the chassis frame, respectively.

[0023] According to the technical solution provided by this utility model, the vehicle side panel transfer trolley includes a chassis frame, a support frame, multiple traveling wheels, and two sets of hanging plate assemblies. The multiple traveling wheels are spaced apart on the chassis frame to support its movement. The support frame includes a support crossbar and at least two support columns, which are spaced apart on the side of the chassis frame away from the traveling wheels and perpendicular to the top surface of the chassis frame. The support crossbar is installed on the support columns and is parallel to the length direction of the chassis frame. The two sets of hanging plate assemblies are spaced apart on the support crossbar. Each hanging plate assembly includes a hanging rod and a connecting piece. The hanging rod is installed on the connecting piece, which clamps the supporting crossbar. The hanging rod is perpendicular to the supporting crossbar, and the distance between the two ends of the hanging rod and the supporting crossbar is equal. According to this solution, when transporting the vehicle side panel, two hanging rods can pass through the door area of ​​the side panel respectively, allowing the side panel to be stably mounted on the two hanging rods. The symmetrical arrangement of the hanging rods allows one side panel transfer trolley to transport two side panels. By clamping the connecting pieces to the supporting crossbars, the distance between the two connecting pieces can be easily adjusted, thereby adjusting the distance between the two hanging rods. This allows the two hanging rods to accommodate different models of side panels. This design facilitates the easy removal of side panels requiring inspection and avoids deformation caused by collisions between side panels, thus preventing any impact on the quality inspection results.

[0044] Taking the stamping workshop for vehicle side panels as an example, during vehicle production, when production conditions change, such as batch changes in vehicle models or adjustments to production process parameters, to ensure that the quality of the vehicle side panels (hereinafter referred to as panels) meets engineering quality management regulations, it is necessary to retain samples for inspection of the initial products (i.e., the panels initially produced after the production change), intermediate products (panels in the middle stages of the production process), and final products (panels in the final stage after the production change). Before quality inspection, vehicle side panel panels need to be transported to a dedicated testing area. Currently, the transfer of panels mainly relies on trolleys. In practice, panels from different production stages are stacked on trolleys, which then transfer the panels to the testing area. This transfer method, to a certain extent, achieves efficient batch transportation of panels, meeting the basic requirements of the production process.

[0045] However, the applicant's observations revealed that due to the significant weight of the vehicle side panels, when inspecting lower panels, it is essential to manually remove the upper panels one by one. This process is not only cumbersome but also time-consuming and labor-intensive. Workers must exercise extreme caution during removal to prevent panels from slipping and causing accidents. After the panels to be inspected are removed, the upper panels must be moved back to their original positions, further increasing the complexity and time cost. Furthermore, repeated movement of panels greatly increases the risk of collisions. These collisions can result in surface scratches, deformation, and other damage, potentially altering the physical properties of the panels and negatively impacting quality inspection results. This could even lead to inaccurate results, posing a potential risk to vehicle manufacturing quality control.

[0046] In view of this, the present invention proposes a vehicle body side panel transfer trolley to solve the above problems.

[0047] Please see Figures 1 to 3 In one embodiment of this utility model, the vehicle side panel transfer trolley 100 includes a chassis frame 1, a support frame 3, multiple wheels 2, and two sets of hanging plate assemblies 4. The multiple wheels 2 are spaced apart and mounted on the chassis frame 1 to support the movement of the chassis frame 1. The support frame 3 includes a support crossbar 31 and at least two support columns 32. The at least two support columns 32 are spaced apart and mounted on the side of the chassis frame 1 away from the wheels 2, and the support columns 32 are perpendicular to the top surface of the chassis frame 1. The support crossbar 31 is mounted on the support columns 32, and the support crossbar 31 is parallel to the length direction X of the chassis frame 1 (see [reference]). Figure 1 (The direction indicated by the middle arrow X); Two sets of hanging plate assemblies 4 are installed at intervals on the support crossbar 31. The hanging plate assembly 4 includes a hanging rod 41 and a connector 42. The hanging rod 41 is installed on the connector 42, and the connector 42 is clamped on the support crossbar 31. The hanging rod 41 is perpendicular to the support crossbar 31, and the distance between the two ends of the hanging rod 41 and the support crossbar 31 is equal.

[0048] Specifically, the chassis frame 1 has a rectangular outer contour and is composed of multiple square tubes connected together. The supporting crossbar 31 is a square tube, and the supporting column 32 is either a square tube or a round tube. The types of traveling wheels 2 include omnidirectional wheels 2a and directional wheels 2b. Both types of traveling wheels 2 are equipped with foot brakes, and there are two of each type. Both omnidirectional wheels 2a and directional wheels 2b are equipped with foot brakes to prevent the vehicle body side panel transfer trolley 100 from moving when statically placed. The connecting piece 42 is clamped to the supporting crossbar 31. When it is necessary to change the distance between the two hanging rods 41, the clamping force of the connecting piece 42 on the supporting crossbar 31 is reduced, allowing the connecting piece 42 to slide on the supporting crossbar 31 as needed. When it is necessary to hang plates on the hanging rods 41, the clamping force of the connecting piece 42 on the supporting rod is increased, preventing the connecting piece 42 from displacing relative to the supporting crossbar 31. The distance between the two ends of the hanging rod 41 and the supporting crossbar 31 is equal, that is, the hanging rod 41 is symmetrically arranged with respect to the supporting crossbar 31. This arrangement helps to balance the torque at both ends of the hanging rod 41 and prevent the connecting piece 42 from shifting to one side.

[0049] According to the solution provided in this embodiment, when transporting the vehicle side panel, two hanging rods 41 can respectively pass through the door portion of the vehicle side panel, allowing the entire vehicle side panel to be stably mounted on the two hanging rods 41. The symmetrical arrangement of the hanging rods 41 allows one vehicle side panel transfer trolley 100 to transport two vehicle side panels. Furthermore, by clamping the connecting piece 42 to the supporting crossbar 31, the distance between the two connecting pieces 42 is easily adjusted, thereby adjusting the distance between the two hanging rods 41, enabling the two hanging rods 41 to accommodate different models of vehicle side panels. This design facilitates the removal of vehicle side panels requiring inspection at any time and avoids deformation caused by collisions between vehicle side panels, thus preventing any impact on the quality inspection results of the vehicle side panels.

[0050] Please see Figure 2 and Figure 4 In one embodiment of this utility model, the connector 42 includes a bolt 421 and two clamping plates 422. The two clamping plates 422 are arranged in parallel, and the bolt 421 passes through the two clamping plates 422. The hanging rod 41 is simultaneously connected to the two clamping plates 422. The hanging rod 41, bolt 421, and two clamping plates 422 enclose a clamping space. A supporting crossbar 31 passes through the clamping space, and the bolt 421 is used to clamp the two clamping plates 422 to the supporting crossbar 31. Specifically, the hanging rod 41 and the clamping plates 422 are welded together. By rotating the bolt 421, the clamping force applied by the two clamping plates 422 to the supporting crossbar 31 can be adjusted, thereby changing the movement state of the clamping plates 422 relative to the supporting crossbar 31. This structure is simple and reliable, and can quickly adjust the distance between the two hanging rods 41 to adapt to the mounting requirements of different plates.

[0051] Further, please refer to Figure 5 In one embodiment of this utility model, the hanging rod 41 includes a main rod 411 and two secondary rods 412. The main rod 411 is perpendicular to the supporting crossbar 31 and is simultaneously connected to two clamping plates 422. The main rod 411 has a sliding cavity, and the secondary rods 412 are movably installed in the sliding cavity. The two secondary rods 412 can extend from both ends of the main rod 411. Since the secondary rods 412 can move within the sliding cavity of the main rod 411 and can extend from both ends of the main rod 411, the length of the entire hanging rod 41 is highly adjustable. For example, in different usage scenarios, if it is necessary to hang thicker plates, in order to avoid the plates colliding with the supporting column 32 or the supporting crossbar 31, the two secondary rods 412 can be stretched to both ends to increase the effective length of the hanging rod 41. Conversely, when the secondary rods 412 are not needed, they can be retracted into the main rod 411 to adapt to the hanging requirements of narrow spaces.

[0052] Furthermore, please refer to Figure 4 and Figure 5 In one embodiment of this utility model, the hanging rod 41 further includes an externally threaded knob handle 413. The externally threaded knob handle 413 includes a handle and a screw installed on the handle. A threaded hole is provided on the side wall of the main rod 411, and the screw extends into the sliding cavity through the threaded hole. The end of the screw away from the handle can abut against the side wall of the secondary rod 412. The externally threaded knob handle 413 is used to abut against the secondary rod 412 when it is necessary to fix the length of the secondary rod 412 extending beyond the main rod 411. When the secondary rod 412 is adjusted to a suitable position, the handle is turned, and the end of the screw abuts against the side wall of the secondary rod 412, generating a large frictional force and clamping force, fixing the secondary rod 412 in the main rod 411, preventing the secondary rod 412 from sliding or loosening due to external force or the weight of the hanging plate, ensuring the structural stability of the hanging rod 41, and ensuring the safety of the hanging plate.

[0053] In one embodiment of this utility model, please refer to Figure 5 The hanging rod 41 also includes a hook 414, which is installed on the end of the sub-rod 412 that extends out of the mother rod 411. The hook 414 prevents the panel from falling off during transportation, thereby improving the safety of the panel during transportation.

[0054] In one embodiment of this utility model, the hanging rod 41 further includes a buffer layer, which is fitted onto the end of the sub-rod 412 extending from the mother rod 411 and the surface of the hook 414. The buffer layer reduces the direct contact pressure between the hook 414 and the end of the sub-rod 412 on the surface of the mounting plate, preventing scratches, wear, or damage to the plate surface caused by the rigid hanging rod 41. Simultaneously, the buffer layer also provides some protection for the sub-rod 412 and the hook 414, thereby improving their service life. The material of the buffer layer includes one of the following: rubber, modified rubber, silicone, etc.

[0055] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the vehicle side panel transfer trolley 100 further includes a barrier structure 5, which includes multiple protective doors 51 and two supports 52. Along the length direction X of the chassis frame 1, the two supports 52 are respectively installed at both ends of the chassis frame 1. Along a direction perpendicular to the length direction X, protective doors 51 are rotatably installed on both sides of each support 52. The protective doors 51 have an open state and a closed state. When the protective door 51 is in the open state, it is perpendicular to the length direction X; when the protective door 51 is in the closed state, it is parallel to the length direction X, and the protective door 51 is connected to the chassis frame 1 by pins. With this arrangement, when the panel is hung on the hanging rod 41, the protective door 51 is in the open state to facilitate the passage of the panel. During the transport of the panel, the protective door 51 is in the closed state, and pins are used to connect the protective door 51 to the chassis frame 1 to prevent the panel from falling and injuring the operator. The protective door 51 and the bracket 52 are connected by a hinge so that the protective door 51 can rotate around the bracket 52.

[0056] In one embodiment of this utility model, the support 52 includes a first protective net 522 and at least two uprights 521. The uprights 521 are vertically installed on the chassis frame 1, and the first protective net 522 is installed between adjacent uprights 521. The protective door 51 includes a gantry 511 and a second protective net 512. The gantry 511 is rotatably installed on the support 52, and the second protective net 512 is installed on the gantry 511. By setting the first protective net 522 and the second protective net 512, it is possible to prevent the edge of the panel from extending beyond the vehicle side panel transfer trolley 100 when the panel shakes or falls, thereby preventing collisions with workers and reducing the risk of collision injuries to workers during the transportation of panels.

[0057] In addition, please see Figures 1 to 3 A handrail 7 is installed on the outside of the column 521 to facilitate the operator to push or pull the vehicle side panel transfer trolley 100.

[0058] In one embodiment of this utility model, the vehicle side panel transfer trolley 100 further includes a jacking device 6, which is mounted on the chassis frame 1 and is located on the same side as the traveling wheels 2. The jacking device 6 can be an American-style or a Japanese-style jacking device. The jacking device 6 being located on the same side as the traveling wheels 2 enables multi-point support for the vehicle side panel transfer trolley 100 in a stationary state, thereby improving the anti-tipping performance of the vehicle side panel transfer trolley 100 in a stationary state and preventing tipping during loading and unloading of panels.

[0059] In one embodiment of this utility model, the support frame 3 further includes reinforcing ribs 33, which are connected to the side wall of the support column 32 and the chassis frame 1 respectively. The reinforcing ribs 33, through a triangular or truss-like structure (similar to the support design of bridges or tower cranes), rigidly connect the support column 32 to the chassis frame 1, forming a stable force transmission path. This reduces stress concentration at the root of the support column 32 (where it connects to the chassis), avoiding problems such as weld cracking due to long-term load, thereby increasing the service life of the support column 32.

[0060] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
