The invention discloses a load-carrying heavy stair climbing vehicle which comprises a U-shaped pushing hand pipe, the U-shaped pushing hand pipe is sleeved with a moving block in a sliding mode, a U-shaped pushing hand dragging plug is fixedly installed at the bottom of the U-shaped pushing hand pipe, and two pushing hand pipes are fixedly installed at the bottom of the moving block. During use, the lengths of the U-shaped pushing hand pipes are adjusted through the moving blocks, after the lengths of the U-shaped pushing hand pipes are adjusted to proper positions, the bearing plate connected with the lower ends of the two pushing hand pipes is opened, the U-shaped fixing plate is driven to move in the vertical direction, the trundle support slides to the vertical face on the U-shaped fixing plate from the parallel face on the U-shaped fixing plate, and the fixed trundle base ascends; when the trundle support ascends, the lower oblique teeth arranged at the top end of the trundle support are meshed with the upper oblique teeth installed in the fixed trundle base, the trundle support is driven to rotate, and therefore the function that the trundle support is automatically opened while the bearing plate is opened is achieved.
本发明公开了一种载重重型爬楼梯车,包括U形推手管,所述U形推手管上滑动套接有移动块,所述U形推手管的底部固定安装有U形推手拖塞,所述移动块的底部固定安装有两个推手管。本发明中,使用时,首先通过移动块对U形推手管长度进行调节,调节至适宜位置后,打开与两个推手管下端连接的承物板,带动U形固定板向垂直方向运动,导致脚轮支架从U形固定板上的平行面滑动至U形固定板上的垂直面,导致固定脚轮座上升,脚轮支架上升导致其顶端开设的下斜齿与固定脚轮座内部安装的上斜齿发生啮合,带动脚轮支架旋转,从而实现在打开承物板的同时自动打开脚轮支架的功能。
