[0020] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0021] like Figure 1 and Figure 2As shown, the DKD vehicle body transport trolley includes a mounting frame 1, a universal wheel 3 is provided at the bottom end of the mounting frame 1, the mounting frame 1 is fixedly connected to a bracket 2, a first connecting plate 4 is provided at the top end of the mounting frame 1, a second connecting plate 5 is provided on the bracket 2, and connecting holes 6 are provided on both the first connecting plate 4 and the second connecting plate; support legs 7 are provided at both ends of the mounting frame 1, and a fixing structure is provided between the support legs 7 and the mounting frame 1. The two connecting plates correspond to the fixing holes at the front and rear ends of the vehicle chassis for mounting the auxiliary body. After the connecting plates are fastened to the chassis, the trolley supports the vehicle and puts it in a suspended posture, avoiding damage to the vehicle body during import and export transportation. The movement of the universal wheel 3 realizes the circulation and transportation function of the vehicle. The support legs 7 provided at both ends of the mounting frame 1 can simulate the wheel size and wheel location, facilitating the loading and unloading, transportation, and auxiliary and replacement of front and rear suspension assembly of vehicles without powertrain and tires.

[0022] like Figure 1 and Figure 2 As shown, the fixing structure includes a fixing plate 8, which is located in the middle of the support leg 7. A fixing rod 9 is connected to the fixing plate 8. The end of the fixing rod 9 passes through the fixing plate 8 and is connected to a nut 10. The fixing plate 8 and the fixing rod 9 press the mounting frame 1 and the support leg 7 together. The fixing rod 9 is threaded at the end and engages the nut 10. The fixing plate 8 and the fixing rod 9 are pressed together to secure the support leg 7 to the mounting frame 1. Loosening the nut 10 allows the support leg 7 to move longitudinally relative to the mounting frame 1. During assembly, this facilitates fore-and-aft adjustment of the support leg 7. After tightening with bolts, the support leg 7 is precisely positioned. Different support legs 7 can be replaced to accommodate different vehicle wheel sizes, achieving reuse and reducing operating costs. Loosening the nut 10 allows the support leg 7 to move laterally on the mounting frame 1 according to the wheel position of different vehicle models. This allows for quick adjustment of the support leg 7 without disengaging the support leg 7, thereby securing the support leg 7 in the desired position and eliminating the need for reassembly.

[0023] like Figure 1 As shown, the long side of the first connecting plate 4 is perpendicular to the mounting frame 1, while the long side of the second connecting plate 5 is parallel to the mounting frame 1. The first connecting plate 4 and the second connecting plate 5 are arranged in pairs. This structure creates a multi-point force distribution. The first connecting plate 4 and the second connecting plate 5 correspond to the fixing holes at the front and rear ends of the chassis for mounting the auxiliary body. The first connecting plate 4 and the second connecting plate 5 are installed in a perpendicular direction to ensure uniform and balanced force distribution.

[0024] like Figure 1 As shown, the support leg 7 is a U-shaped structure, and a baffle 13 is provided at the end of the support leg 7. The baffle 13 is an inclined structure. The U-shaped support leg 7 can support the ground to form a certain anti-tilting effect, which facilitates the operation process of fixing the device to the vehicle body. The baffle 13 can prevent the device from causing bumps and scratches to the vehicle or personnel during transportation.

[0025] like Figure 1 As shown, the bottom of the first connecting plate 4 and the second connecting plate 5 are both provided with screw sleeves 14. The screw sleeves 14 are provided with threaded holes inside to enhance the strength of the threaded connection, thereby improving the anti-loosening ability and load-bearing capacity of the fixing rod 9.

[0026] like Figure 1 As shown, the mounting frame 1, bracket 2, and legs 7 are all square tube structures. The main body of the trolley is constructed by welding square tubes, which is easy to process into the desired shape and can also reduce manufacturing costs. Since the trolley needs to bear the weight of the vehicle body, the structural strength of the square tubes is reliable and can provide reliable support.

[0027] like Figure 1 As shown, a reinforcing plate 12 is welded between the mounting frame 1 and the bracket 2. The reinforcing plates 12 are symmetrically arranged to expand the connection area between the mounting frame 1 and the bracket 2 and improve the connection strength between the two.

[0028] like Figure 1 As shown, a mounting plate 11 is detachably connected between the universal wheel 3 and the mounting frame 1. A plurality of bolt holes are provided on the mounting plate 11 to facilitate the disassembly, assembly and replacement of the universal wheel 3.

[0029] like Figure 1 and Figure 2 As shown, the fixing rods 9 are located on both sides of the legs 7. The above structure is used to prevent the legs 7 from moving laterally on the mounting frame 1 after being fastened, which is beneficial to improving stability.

[0030] The installation process is as follows: place the trolley on the circulation equipment and fix it, deliver it to the chassis installation area, use the electric hoist to lift the trolley onto the AGV trolley, and the vehicle arrives at the workstation for assembly; confirm the placement of the trolley relative to the chassis, install it at the front and rear sub-body positions of the chassis, align the connection holes 6 of the trolley with the holes on the chassis for installing the sub-body, and tighten them with bolts to simulate the front and rear suspension of the vehicle, and use the universal wheel 3 to realize the movement of the DKD vehicle, thus meeting the circulation and transportation needs.

[0031] The DKD vehicle body transport trolley suspends the vehicle while realizing off-line transportation and circulation of the vehicle, which facilitates employees to perform assembly operations and improves production efficiency; the support legs 7 are easy to install and replace, and can be moved and adjusted on the mounting frame 1 to meet the transportation needs of various vehicle models; the overall structure is simple, easy to install and disassemble, with low cost and long service life.

[0032] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
