摘要:
A rotary rail car dumper has a rail car platform (4) forming part of a rigid tipping structure (2) which, through end ring members (8), is mounted for rotation about a central longitudinal axis for tipping a rail car to dump its contents. Between the rail car platform and the ring members are pin joint connections (20) allowing flexure under gravity loading independently of the ring members, at least before tipping. The maximum stresses occurring during operation of the dumper are thereby reduced. The dumper installation is also provided with means (60,60a) for extending the length of the rail car platform in order to handle rail cars of different lengths in unit trains.

The invention relates to a tilting device (10) for emptying materials, preferably bulk materials, out of railcars (22) which are open at the top. The tilting device comprises a tilting frame (12) which can be pivoted about a pivot axis (D), a platform (16) which is connected to the tilting frame (12) for receiving at least one railcar (22), a clamping arm (14) which is pivotally attached to the tilting frame (12), a locking device (25) for preventing a relative movement between the tilting frame (12) and the clamping arm (14), and a bracket (34). The bracket is attached to the clamping arm (14) such that the clamping arm rests at least partly on an upper edge of at least one of the lateral walls of the railcar (22) in a tilting position of the tilting device (10), the tilting frame (12) being pivoted about the pivot axis in said tilting position, and a hydraulic cylinder (42) is attached to the bracket (34).
摘要:
A weighing system for a rotary rail car dumper. The rotary rail car dumper includes a frame assembly that receives a rail car including contents to be weighed. A series of trunnions are positioned to rotatably support the frame assembly and allow the frame assembly to be rotated to dump the contents of the rail car. A weight gauge is positioned on each of the trunnions. The weight gauge generates a signal based upon the force applied to the respective trunnion by the weight of the frame assembly and rail car. In one embodiment, the weight gauges are a series of strain gauges that generate an electrical signal based upon the force applied to the strain gauge. A control unit receives the electrical signals from the strain gauges and determines the weight of the rail car before and after the contents of the rail car have been dumped.
