Abstract
Description
Изобретение относится к безрельсовому транспорту, в частности к ручным средствам для транспортировки груза по лестницам и площадкам. The invention relates to trackless transport, in particular to manual means for transporting goods along stairs and platforms.
Известна ручная одноосная тележка для транспортировки груза по лестницам, содержащая платформу с водилом, установленную на оси с ходовыми колесами посредством механизма подвески. Known manual uniaxial trolley for transporting goods along the stairs, containing a platform with a carrier mounted on an axis with running wheels by means of a suspension mechanism.
В описываемой тележке радиус выбирают из условия
h < R<b,
где h- высота ступеньки лестницы, b - ширина ступеньки лестницы, R - радиус ходовых колес.In the described trolley, the radius is selected from the condition
h <R <b,
where h is the height of the stairs, b is the width of the stairs, R is the radius of the running wheels.
На чертеже показана тележка, вид сбоку,
Тележка содержит ось 1 с ходовыми колесами 2. На оси 2 посредством механизма подвески 3 установлена платформа 4 с водилом 5.The drawing shows a trolley, side view,
The trolley contains an axis 1 with running wheels 2. On an axis 2, a platform 4 with a carrier 5 is mounted by means of a suspension mechanism 3.
Устройство работает следующим образом. The device operates as follows.
Тележку передвигают по площадке до упора колес 2 в вертикальную стену ступеньки. Под действием приложенного усилия к водилу 5, колеса 2 обкатываются вокруг кромки ступеньки, заходят на ее горизонтальную часть и перемещаются до упора в вертикальную стену следующей ступеньки. Дальше все повторяется. The trolley is moved across the platform until the wheels 2 rest in the vertical wall of the step. Under the action of the applied force to the carrier 5, the wheels 2 run around the edge of the step, go to its horizontal part and move all the way into the vertical wall of the next step. Then everything repeats.
Вниз по лестнице все идет аналогично, только наоборот. Down the stairs everything goes the same way, just the opposite.
