[0041] It should be noted here that: by setting the steering assembly, it is convenient to turn the platform 1, thereby improving the maneuverability of the platform 1.

[0042] See also Fig. 9 and Fig.10 The plug-in assembly shown in the figure includes a plug-in cavity 1301 opened on the side of the steering rod 1203 close to the steering cylinder 1202, the plug-in cavity 1301 is connected to the plug-in rod 1302 through an extrusion assembly, the plug-in rod 1302 is matched with the inner wall of the steering cylinder 1202, and the steering rod 1203 is provided with a driving assembly for driving the plug-in rod 1302;

[0043] It should be noted here that: by setting the plug-in assembly, the connection between the steering cylinder 1202 and the steering rod 1203 is facilitated, thereby realizing the connection of the front steering wheel group 2.

[0044] See also Fig. 9 and Fig.10 The extrusion assembly shown in the figure includes an extrusion plate 1401 slidably connected to the plug-in cavity 1301, one end of the plug-in rod 1302 is connected to the extrusion plate 1401, a second spring 1402 is fixedly connected to the side of the extrusion plate 1401 away from the plug-in rod 1302, and the other end of the second spring 1402 is connected to the inner wall of the plug-in cavity 1301;

[0045] It should be noted here that the extrusion assembly is provided to provide an elastic extrusion driving force for the plug-in rod 1302 .

[0046] See also Fig. 9 and Fig.10 The driving assembly shown in the figure includes a driving hole 1501 opened on the side wall of the steering rod 1203, the driving hole 1501 is communicated with the plug-in cavity 1301, the driving hole 1501 is slidably connected with a driving plate 1502, and one end of the driving plate 1502 is connected to the extrusion plate 1401;

[0047] It should be noted here that: through the provision of the driving assembly, it is convenient to pull the plug-in rod 1302, thereby facilitating the connection and disassembly between the plug-in rod 1302 and the steering cylinder 1202.

[0048] See also Figure 2 and Figure 7 , the pushing assembly shown in the figure includes a pushing rod 1601 hinged to the side of the third fixing plate 1206 away from the platform 1, and the other end of the pushing rod 1601 is provided with a traction ring 1602;

[0049] It should be noted here that: through the setting of the pushing component, when the platform 1 needs to be moved, the pushing rod 1601 can be pulled manually or the traction ring 1602 at one end of the pushing rod 1601 can be connected to the traction vehicle, so that the traction vehicle can pull the platform 1, and then the platform 1 can be moved and transported in multiple ways. When the platform 1 needs to turn, the pushing rod 1601 can be pushed to one side to drive the front steering wheel group 2 to turn accordingly. At the same time, the side wheel group 3 will follow the rolling, and the rear steering wheel group 4 will adaptively turn and can turn on the spot with a smaller turning radius, thereby improving the maneuverability and flexibility of the platform 1 as well as the convenient walking and steering functions.

[0050] Working principle: When the platform 1 is in use, firstly, the first fixing plate 901 and the first mounting plate 902 are mounted to the side wall of the platform 1 by means of bolts 903. When the platform 1 needs to be transported, the platform 1 is lifted up by means of a jack or other related lifting devices, and then the front steering wheel group 2, the side wheel group 3 and the rear steering wheel group 4 are installed one by one to the corresponding positions. When installing the front steering wheel group 2, firstly, the front steering wheel group 2 is moved to the first mounting plate 902, and then the front steering wheel group 2 is lifted up, so that the key rod 905 at one end of the connecting rod 8 of the front steering wheel group 2 is inserted into the key hole 904 on the first mounting plate 902, and then the L-shaped plate 1001 is rotated by means of the sliding assembly, and the L-shaped plate 1001 is slid so that one end thereof is located above the key rod 905.

[0051] When the L-shaped plate 1001 rotates to the top of the key rod 905, the L-shaped plate 1001 is pushed to move close to the key rod 905. When the first mounting hole 1002 on the L-shaped plate 1001 is inserted into the side wall of the key rod 905, as the L-shaped plate 1001 continues to move, when the two limit blocks 1004 on the side wall of the L-shaped plate 1001 abut against the side wall of the key rod 905, the two limit blocks 1004 will be pushed to retract into the second mounting hole 1003 under the interaction force of the inclined surface 1006 and the guiding action of the telescopic component. The key rod 905 is continuously moved closer to the key rod 905. When the two limit blocks 1004 are matched with the limit holes 1005, the two limit blocks 1004 will be pushed into the limit holes 1005 under the elastic pushing action of the telescopic assembly, and will abut against the bottom wall of the limit holes 1005, so that the key rod 905 is limited by the abutting action of the two limit blocks 1004, and then the connection and limit of the front steering wheel group 2 are realized, and then the side wheel group 3 and the rear steering wheel group 4 are connected and installed one by one according to the same operation method, and no more details are given here;

[0052] After the front steering wheel group 2, the side wheel group 3 and the rear steering wheel group 4 are connected and installed, the steering rod 1203 can be placed between the steering cylinders 1202 on one side of the two front steering wheel groups 2, and then the driving plate 1502 is pulled to make the plug-in rod 1302 at one end of the extrusion plate 1401 shrink into the plug-in cavity 1301. After the plug-in rod 1302 shrinks into the plug-in cavity 1301, the steering rod 1203 can be aligned with the steering cylinder 1202, and the pulling of the driving plate 1502 is released. At this time, the plug-in rod 1302 will be inserted into the steering cylinder 1202 under the elastic action of the second spring 1402, thereby realizing the connection between the steering rod 1203 and the steering cylinder 1202;

[0053] After the steering cylinder 1202 is connected to the steering rod 1203, the pushing rod 1601 can be manually pulled or the traction ring 1602 at one end of the pushing rod 1601 can be connected to the tractor, so that the tractor can pull the platform 1, thereby realizing the mobile transportation of the platform 1 in multiple ways. When the platform 1 needs to be turned, the pushing rod 1601 can be pushed to one side to drive the front steering wheel group 2 to turn accordingly. At the same time, the side wheel group 3 will follow the rolling, and the rear steering wheel group 4 will turn adaptively and can turn on the spot with a smaller turning radius, thereby improving the stability of the platform 1. It has flexible and convenient walking and steering functions. At the same time, under the action of the connecting components and the limiting components, the front steering wheel group 2, the side wheel group 3 and the rear steering wheel group 4 present a split component structure, which reduces the weight of the components and makes the installation operation more convenient. At the same time, when the platform 1 does not need to be transported, the space occupied can be reduced by disassembling the front steering wheel group 2, the side wheel group 3 and the rear steering wheel group 4. The standardized structural design of the front steering wheel group 2, the side wheel group 3 and the rear steering wheel group 4 can be suitable for the connection, installation and use of multiple sets of platforms 1, thereby reducing resource waste and improving utilization.
