FIELD: conveyer making.
SUBSTANCE: stand consists of a section of a belt installed on a frame, with provision putting samples of the transported load on it, supports for the belt, devices for measuring tension in the belt and equipment of pulling it. The frame is made in the form of a trolley with provision for moving it along the guiding frames. The supports of the belt are made in the form of spiral rods with a round cross-section fixed to posts of the frame by their free ends. The section of the tubular belt can move freely inside the spirals. The free ends of the belt are fixed to round shaped caps, linked to flexible elements with built measuring devices from the frame. The ends of the spirals on the posts of the frame are fixed using plates with provision for rotation about the posts of the frame and fixation on them. The trolley is made with demounting equipment, allowing for changing its length, with supports for the spirals and kinematically linked to a counterbalance with interchangeable loads using a rope through a deflection unit. The posts of the frame and plates are made with openings for letting in flexible elements.
EFFECT: provides for possibility of realising support of the tubular conveyer belt on the investigation stand with different values of construction and operation parameters of these units.
