The carrier convenient to carry and transport comprises a supporting plate and a vertical frame which are mutually rotated and folded, a pair of universal wheels are symmetrically installed on the two sides of the front end of the supporting plate, a pair of driving wheels are symmetrically installed on the two sides of the bottom end of the vertical frame, and a ramp auxiliary structure is arranged between the two driving wheels; the ramp auxiliary structure comprises a first connecting rod connected between the axes of the two driving wheels, a first gear fixedly connected to the outer wall of the first connecting rod in a sleeved mode, a second gear connected with the outer ring of the first gear in a meshed mode, a second connecting rod coaxially connected with the second gear and a ratchet wheel fixedly connected to the outer wall of the second connecting rod in a sleeved mode, and an anti-reverse-rotation structure is arranged on the periphery of the ratchet wheel. By arranging the ramp auxiliary structure, the ramp auxiliary structure limits the rotating direction of the driving wheel, so that when the carrying vehicle travels on the ramp, the driving wheel cannot roll backwards, the situation that the carrying vehicle retreats when the carrying vehicle loses thrust is effectively prevented, meanwhile, forward rolling of the driving wheel is not blocked, and the driving wheel is prevented from moving backwards when the carrying vehicle loses thrust. Therefore, the carrier can continue to advance on the ramp conveniently.
本发明公开了一种方便携带运输的搬运车,包括相互转动折叠的托板和立架,所述托板的前端两侧对称安装有一对万向轮,所述立架的底端两侧对称安装有一对驱动轮,且两个驱动轮间设置有坡道辅助结构;所述坡道辅助结构包括有连接在两个驱动轮轴心之间的连杆一、套接固定在连杆一外壁的齿轮一、与齿轮一外圈啮合连接的齿轮二、与齿轮二同轴连接的连杆二以及套接固定在连杆二外壁的棘轮,该棘轮的外围设置有防反转结构。本发明通过设置坡道辅助结构,坡道辅助结构限定了驱动轮的转动方向,使得搬运车在上坡道行进时,驱动轮无法向后滚动,进而有效防止了搬运车在失去推力时发生后退的情况,同时驱动轮向前滚动不受阻,进而方便搬运车继续在坡道上行进。
