It is not what the present invention wants to protect. I will not repeat them here again.
[0034] The working principle of the present invention is: according to the size of the material to be transported, use the control unit to activate the hydraulic cylinder to adjust the height of the lifting platform, put the material to be transported into the lifting platform in the transport box through the operating port, and then turn the operating handle, Driven by the screw rod, the first clamping plate approaches the second clamping plate to clamp the material on the lifting platform. After the initial clamping, push the operating handle to make the positioning groove approach the positioning column, and then continue to rotate The handle is operated to make the second buffer spring elastically deform. At this time, the corresponding positioning groove is sleeved on the positioning column to complete the fixing of the operation handle. Then start the walking chassis through the control unit, and move to the destination by itself with the cooperation of the lidar sensor and the navigation map built into the control unit. When forward or backward is obstructed, the arc-shaped anti-collision buffer shrapnel will buffer to avoid damage to the device.
