The plurality of columns 5 are arranged along the Y direction (i.e., the width direction of the working platform in the figure), and the workpiece is supported between two adjacent columns 5.

[0036] With the above structure, because the movable platform 4 is detachably installed on one or both sides of the fixed platform 3, it is convenient for the operator to choose whether to install the movable platform 4 according to the type of workpiece and the working method, so as to change the length and working method of the entire working platform.

[0037] If you only need to use the work platform to transport workpieces such as AB beams, longitudinal beams, and reinforcement plate pre-assemblies, and only need to perform lifting actions to complete the under-vehicle assembly of the workpieces, you can only use the fixed platform 3, and there is no need to install the movable platform 4. The workpiece can be placed flat on the fixed platform 3, and the traveling trolley 1 can be used to transport the workpiece to the assembly position under the vehicle, and then the lifting device 2 can be used to lift the workpiece to the working position, and then the workpiece can be assembled.

[0038] If you need to transfer a long and large workpiece such as a floor, and move the workpiece horizontally from the work platform to the vehicle, you need to install the movable platform 4 on the fixed platform 3, and place the floor vertically between two adjacent columns 5. Use the columns 5 to support the floor. This not only allows multiple floors to be transferred at one time, but also facilitates the floor to be pulled vertically from the door to the inside of the vehicle. Use the traveling trolley 1 to transport the workpiece to the loading position on one side of the vehicle body, and then use the lifting device 2 to lift the workpiece to the same height as the door or end door frame, and then move the workpiece horizontally to the vehicle body for assembly.

[0039] The above structure can be used for the transportation of different types of workpieces, and can also be used for different operating methods such as under-vehicle assembly of workpieces and lateral transfer on the vehicle side, thus realizing multi-purpose use of one machine with strong versatility. It can also ensure the safety of workpieces during transportation, improve operating efficiency and reduce labor intensity.

[0040] In this embodiment, the width of the movable platform 4 is the same as that of the fixed platform 3. After installation, the upper surfaces of the movable platform 4 and the fixed platform 3 are on the same plane, so that the upper surface of the entire working platform is flat, ensuring that the workpiece is stable and reliable after being placed, and will not be damaged.

[0041] In this embodiment, the movable platform 4 is detachably mounted on the fixed platform 3 through the plug-in structure 6. The installation using the plug-in structure 6 makes the operation simple and convenient, can realize quick switching, improve work efficiency, and reduce labor intensity.

[0042] like Figure 3 and Figure 5As shown, in this embodiment, the plug-in direction of the plug-in structure 6 is the X direction (i.e., the length direction of the working platform in the figure), and the movable platform 4 is located on both sides of the length direction of the fixed platform 3 after being plugged in, thereby increasing the length of the entire working platform. Further preferably, the plug-in structure 6 includes at least two plug-in tubes 61 arranged on the fixed platform 3, and the plug-in tubes 61 can be square tubes as shown in the figure, or round tubes as required. Further preferably, a plug-in tube 61 is arranged on each side of the fixed platform 3 in the Y direction, and the plug-in tube 61 extends along the X direction of the fixed platform 3. The plug-in tube 61 can be arranged throughout the length, or only one section can be arranged on each side of the X direction of the fixed platform 3. At least two plug-in columns 62 are arranged on one side of the movable platform 4, and the plug-in column 62 matches the cross-sectional shape of the plug-in column 61. The plug-in column 62 is arranged corresponding to the plug-in column 61, and the plug-in column 62 is correspondingly inserted into the plug-in column 61. The plug-in column 61 and the fixed platform 3 and the plug-in column 62 and the movable platform 4 are fixed by welding. The plugging tube 61 and the plugging column 62 are provided with corresponding plugging holes 63, and T-shaped positioning pins 64 are inserted into the corresponding two plugging holes 63 to realize the fixed connection between the fixed platform 3 and the movable platform 4. In this way, the stability of the entire working platform after plugging and the supporting capacity of the working platform can be ensured, and quick disassembly and assembly can be realized.

[0043] like Figure 1 and Figure 3 As shown, in this embodiment, further, detachable movable platforms 4 are respectively installed on both sides of the fixed platform 3 in the X direction, so as to maximize the total length of the working platform, and a group of columns 5 are respectively arranged on the outside of the two movable platforms 4, and the two groups of columns 5 are arranged one by one. In this way, when the floor is transported, both sides of the floor can be inserted between the columns 5 at the same time, and both sides of the floor are supported at the same time, ensuring that the floor is stable and reliable during the transportation process, improving safety, and when the floor moves horizontally, it can also play a certain guiding role, ensuring that the floor is stable and reliable during the horizontal movement.

[0044] In this embodiment, the column 5 can be installed on the movable platform 4 in a fixed manner, such as being directly welded on the movable platform 4, or being fixed on the movable platform 4 by fasteners such as bolts. The column 5 can also be installed on the movable platform 4 in a detachable manner, such as being installed by a plug-in structure, and a plurality of installation sockets (not shown in the figure) are provided on the movable platform 4, and the bottom of the column 5 is inserted into the installation socket to realize the connection between the column 5 and the movable platform 4. When the column 5 is not needed, it can also be not installed. At the same time, when the movable platform 4 does not need to be installed, the movable platform 4 and the column 5 can be conveniently placed to reduce the occupied space during storage.

[0045] In this embodiment, at least one set of guide rolling assemblies 7 is respectively arranged on both sides of the movable platform 4, and the workpiece is supported above the guide rolling assemblies 7, and the workpiece moves along the X direction on the guide rolling assemblies 7. In this way, the friction between the floor and the platform surface can be reduced when the workpiece moves horizontally, making the floor and other workpieces move horizontally more easily and labor-saving, and facilitating the horizontal movement of the floor and other workpieces after lifting, so that the floor can be manually pulled into the vehicle through the side door or end door of the vehicle body. This process can be completed by a single person, which is convenient and fast.

[0046] In this embodiment, it is further preferred that a set of guide rolling assemblies 7 is provided between every two adjacent columns 5 to facilitate the transport of multiple floor panels at one time and ensure that each workpiece installed between the columns 5 can be moved laterally by the guide rolling assembly 7.

[0047] like Figure 4 As shown, in this embodiment, preferably, the guide rolling assembly 7 includes a rolling seat 71 and a drum wheel 72 that is wide outside and narrow inside, and the inner side surface of the drum wheel 72 is a plane or an inclined surface. In this way, the bottom surface of a workpiece such as a floor can be directly placed on the cylinder in the middle of the drum wheel 72, or the two edges of the bottom of the floor are supported on the two inclined surfaces of the drum wheel 72, which can provide stable support and facilitate the horizontal movement process. There will be no friction between the surface of the workpiece such as the floor and the drum wheel 72, avoiding damage to the surface of the workpiece such as the floor.

[0048] like Figure 1 and Figure 2 As shown, in this embodiment, protective pads 8 are installed on the table tops of the fixed platform 3 and the movable platform 4. The protective pads 8 are made of rubber or nylon material to ensure that the surface of the workpiece is not damaged. The protective pads 8 are further preferably in a long strip structure, which is intermittently arranged along the width direction (Y direction) of the fixed platform 3 and the movable platform 4. This is conducive to ensuring that the workpiece will not be scratched during the movement, and it is also conducive to reducing the friction between the workpiece and the protective pads 8 during the movement, making the movement more labor-saving.

[0049] In this embodiment, the lifting device 2 adopts a scissor lift, which has a stepless speed regulation function and a remote control electric lifting function, and has a self-locking function after lifting. The up and down electric lifting operations are controlled by a remote control and a control box. When the electrical control fails, it can be lowered manually. The main structure of the scissor lift adopts a high-strength steel structure to ensure the safety and stability of long-term lifting operations.

[0050] In this embodiment, the walking device 1 is a mobile trolley, including a body and wheels, with a stepless speed regulation function, which can be controlled by a remote controller to move forward, backward and turn, and conveniently drive the workpiece above to move to any position to cooperate with different working methods. This trolley adopts a charging method, and the charger and battery are integrated in the trolley, and it can be charged by simply connecting an external power supply.

[0053] 2. The movable platform of the working platform is fixedly connected to the fixed platform by plugging, which is simple and convenient to operate, can achieve quick switching, improve working efficiency and reduce labor intensity.

[0054] 3. The work platform is equipped with guide rolling components in the gaps between the columns on both sides to facilitate the lateral movement of workpieces such as floors after lifting, so that the floors can be manually pulled into the vehicle through the side doors or end doors of the vehicle body. This process can be completed by one person, which is convenient and quick.

[0055] Embodiment 2:

[0056] The difference from the first embodiment is that, in this embodiment, a supporting platform (not shown in the figure) is added between the fixed platform 3 and the top of the lifting device 2. The supporting platform is installed below the fixed platform 3 through a rotating mechanism. The supporting platform is fixedly installed on the top of the lifting device 2, and the fixed platform 3 can rotate around the supporting platform on a horizontal plane.
