The invention belongs to the technical field of transportation equipment, and particularly relates to a carrying trolley and an operation method thereof. Comprising a pull rod assembly, a storage plate, a driving motor arranged at the bottom of the pull rod assembly, a transmission assembly connected with the output end of the driving motor, sun gears hinged to the two ends of the transmission assembly, and triangular star-shaped connecting pieces arranged on the outer sides of the sun gears and fixedly connected with the transmission assembly. The planetary gears are meshed with the sun gear and hinged to the three ends of the triangular star-shaped connecting piece respectively, the idler wheels are connected with the planetary gears in a one-to-one correspondence mode, and the sun gear rotates in one direction relative to the transmission assembly. According to the carrying trolley, when the carrying trolley climbs stairs, the driving motor drives the triangular star-shaped connecting piece and the transmission assembly to synchronously rotate anticlockwise so that idler wheels at the end of the triangular star-shaped connecting piece can climb the stairs in an assisting mode, meanwhile, a planetary gear rotates anticlockwise to drive the idler wheels to rotate anticlockwise, and the triangular star-shaped connecting piece and the idler wheels both have the assisting effect; and the physical strength of a user is saved.
本发明属于运输设备技术领域,具体涉及一种搬运小车及其运行方法,包括拉杆组件、置物板、设于拉杆组件底部的驱动电机、与驱动电机输出端连接的传动组件、与传动组件两端铰接的太阳齿轮、设于太阳齿轮外侧并与传动组件固定连接的三角星型连接件、与太阳齿轮啮合并分别与三角星型连接件的三个端部铰接的行星齿轮,以及与行星齿轮一一对应连接设置的滚轮,太阳齿轮相对传动组件单向转动。本申请的一种搬运小车,在爬楼时,驱动电机驱动三角星型连接件与传动组件同步逆时针转动,以实现三角星型连接件端部的滚轮进行助力爬楼,同时,行星齿轮进行逆时针转动带动滚轮逆时针转动,三角星型连接件和滚轮都具有助力效果,节省使用者的体力。
