The method changes the method of assembling the hood and the vehicle body by hoisting and transporting in the prior art, optimizes the installation process of the hood 1 and the vehicle body, facilitates the operation, and greatly improves the efficiency of assembling the hood. At the same time, it is also more convenient for assembling the hood with a complex head shape and a pipeline and equipment mounting frame at the bottom, which is not easy to hoist and transport, and the vehicle body. It can be applied to the assembly of any head shape hood 1 and the vehicle body, and has stronger versatility. At the same time, since the hood 1 to be assembled is transported to the assembly position with the vehicle body by a ground moving mechanism, the safety factor is higher, and compared with the traditional hoisting and transportation method, the operation process is safer and more reliable.

The device changes the method of assembling the hood and the vehicle body by hoisting and transporting in the prior art, optimizes the installation process of the hood 1 and the vehicle body, facilitates operation, and greatly improves the efficiency of assembling the hood. At the same time, it is also more convenient for assembling the hood with a complex head shape and a pipeline and equipment mounting frame at the bottom, which is not easy to hoist and transport, and can be applied to the assembly of the hood 1 with any head shape and the vehicle body, and has stronger versatility. At the same time, since the hood 1 to be assembled is transported to the assembly position with the vehicle body through a ground moving mechanism, the safety factor is higher, and compared with the traditional hoisting and transportation method, the operation process is safer and more reliable.

In this way, during assembly, the hood 1 and the support device are transported twice, which can reduce the weight and height of each transportation of the ground transportation equipment, making the transportation more stable and reliable. At the same time, the first adjustment mechanism 5 in the X and Y directions and the second adjustment mechanism 6 in the Z direction are installed on the first support device 3 and the second support device 4 respectively. By adjusting the position of the second support device 4 in the X and Y directions, the position adjustment of the hood 1 in the X and Y directions is realized, which is also conducive to simplifying the overall structure of the support device and reducing the cost of the device. At the same time, it is also conducive to reducing the difficulty of adjustment, making the adjustment more convenient and quick, and greatly improving the working efficiency.

[0070] The first adjustment mechanism 5 is set to four groups, which are evenly distributed around the first support platform 31. The first adjustment mechanism 5 pushes the second support device 4 installed on the first support platform 31 from the side to adjust the position of the second support device 4 in the X and Y directions, thereby adjusting the position of the head cover 1 in the X and Y directions.

[0071] The first supporting platform 31 preferably adopts a frame structure, which is formed by splicing and welding an upper platform 311, a lower platform 312, and a plurality of vertical beams 313 supported in the middle, the lower platform 312 is fixedly connected to the ground moving vehicle 2, and the second supporting device 4 is placed on the upper platform 311. Further preferably, the upper platform 311 and the lower platform 312 are both made of rectangular metal plates with a certain thickness, and the four sets of first adjustment mechanisms 5 are respectively installed on the four sides of the upper platform 311 and the lower platform 312.

[0072] In this embodiment, further, the space between the upper platform 311 and the lower platform 312 is used as a matching part for matching with ground transportation equipment (such as a forklift), that is, the space between the upper platform 311 and the lower platform 312 is used as a forklift slot 33 for the forklift to move the first supporting device 3.

[0073] The structure of the first support platform 31 can ensure sufficient support strength and improve the load-bearing capacity, and is also conducive to reducing weight.

By using the first support column 421 and the second support column 422 to support the hood 1, it is convenient to select an easy support point at the bottom of the hood 1 for support and fixation, so that it will not be affected by the bottom pipeline mounting frame and the equipment mounting frame, and can achieve the effect of stable support. The first support column 421 and the second support column 422 can be directly welded to the second support platform 41.

[0080] In this embodiment, it is further preferred that the second support platform 41 includes a support frame 411 and a fixed platform 412 installed at the bottom of the support frame 411, and a bottom fastening structure 43 is provided on the fixed platform 412 for fixed connection with the upper platform 311 of the first support platform 31, and the hood connection mechanism 42 and the lifting mechanism 61 are both fixedly installed on the support frame 411. The support frame 411 adopts a frame structure formed by splicing and welding a plurality of cross beams and longitudinal beams, and the fixed platform 412 adopts a metal plate structure with a certain thickness. The support frame 411 and the fixed platform 412 are welded together or fixedly connected by bolts, which can ensure the support strength and also help to reduce the weight of the device.

[0082] In this embodiment, further, the lifting mechanism 61 preferably adopts a hydraulic lifting mechanism, and four groups are provided, the bottom is fixed to the support frame 411 by bolts, and the top is provided with a structure convenient for connecting with the hood 1. The four groups of lifting mechanisms 61 are used to lift the hood 1 at the same time, so that the lifting and lowering of the hood 1 is more stable, which is conducive to quickly adjusting the height of the hood 1 and achieving docking with the vehicle body. The lifting mechanism 61 can be set according to the structure of the bottom of the hood 1, as long as it can ensure the stable lifting and lowering of the hood 1.

[0083] Furthermore, the support frame 411 has a matching structure for matching with ground transportation equipment (such as a forklift), and the matching structure is a forklift groove 46, which ensures that it can be transported by a forklift. The forklift groove 46 is made of a square tube, and the square tube is welded to the inside of the support frame 411 to facilitate the forklift's fork arm to extend into and transport the second support device 4 to be fixedly connected to the first support device 3.

[0088] 3. Use a forklift to fork the preassembled connection body of the head cover 1 and the second supporting device 4 onto the first supporting device 3, and fasten the second supporting device 4 and the first supporting device 3 firmly.

[0089] 4. Move the Namu wheel vehicle to the vehicle body side, and adjust the gap between the hood 1 and the vehicle body through the Namu wheel vehicle and the first supporting device 3.
