BELT CONVEYOR UNLOADING TROLLEY Russian patent published in 2004 - IPC

FIELD: mechanical engineering; materials handling facilities. SUBSTANCE: invention relates to devices for intermediate unloading of belt conveyor. Proposed trolley contains frame on rolls, unloading and deflecting drums over which load- carrying belt passes, and drive device. Drive device is made in form of drums with drive located out of the limits of trolley and coupled with trolley by means of pull cable whose lower span passes over one part of cable sheaves mounted on trolley frame equipment with pull cable dampers and upper span is connected through turnbuckle with intermediate span passing over other part of cable sheaves. Drive device is provided with deflecting sheaves and support rollers, and trolley has two-hose hopper-divider and platform. Invention makes it possible to provide free access to drive owing to modification of design of trolley proper and mounting of drive out of the limits of trolley, to improved conditions of manual control of trolley and facilitate mounting, adjusting and servicing at high reliability and electric safety. EFFECT: improved reliability and safety in operation. 2 cl, 3 dwg
