Title: Tipping wagons, more especially for rail vehicles
IPC: B61D9/02
Filed: 1954-07-21
Abstract: 779,900. Tipping vehicles. VEREINIGTE WESTDEUTSCHE WAGGONFABRIKEN AKT.-GES. July 21, 1954 [Feb. 24, 1954], No. 21288/54. Classes 103(4) and 108(1). A tipping vehicle, especially a rail wagon, comprises a hopper mounted for tipping movement by means of a hydraulic medium maintained under pressure by a pneumatically-driven pump, means being provided for connecting the pump to any selected one of a plurality of sources of coinpresed air, and an energy accumulator being provided in which energy for tipping the hopper can be stored and used as required. In the arrangement shown in Fig. 1, a compressedair container 1 is charged through a pipe 3 from a compressed-air supply pipe 4 extending along the train of wagons. The container 1 is connected by a pipe 8, control cock 9, water separator 10 and glycol receiver 11 to the driving mechanism 12 of a hydraulic pump 13. The pump is adapted to draw liquid from a container 14 and discharge it through pipe 16 control valve 17, pipe 18, change-over cock 19 and pipe 27 to the tipping cylinders 2a, 2b. Valve 17 and control cock 9 are connected to operate together. The charging of the container 1 may be done from a stationary source of compressed air, through a pipe 24 connected to the source at point 25 or 26. Means are also provided so that the wagon can be tipped by using an external source of liquid under pressure, in which case change-over cock 19 is positioned to connect the pipe 27 not to pipe 18 but to pipe 28. The cock 19 is joined by a connection 46 to pivoted flaps 45 one or other of which must be swung out of the way before the source of pressure liquid can be connected to connections 29, 31, or 30, 32. 34 is a relief valve allowing pressure liquid to return by connection 31 or 32, when the wagon has reached its extreme tilted position. A control cock 33, control valve 17 and control cock 9 are connected together by a connection 47 so that tipping may be controlled by a tingle lever whether the energy is derived from the container I or from the pressure liquid source. In the arrangement shown in Fig. 2, energy is stored in a spring accumulator 36, comprising two compression springs 56 in slotted tubes 55, the springs bearing at one end against a fixed plate 57 and at the other end against a transverse bearer 58 connected to a piston rod 63 in a cylinder 38. When hydraulic medium is pumped to the cylinder 38 through pipe 16, the piston 62 is displaced to the right, compressing the springs 56, and eventually in the extreme position of the piston, liquid in the cylinder flows through a by-pass pipe 40 back to the reservoir 14. The transverse bearer 58 may be secured in its extreme right hand position by a locking pawl 52. If through lack of use leakage of liquid from cylinder 38 occurs, this can be made good by means of a small pump 53. To tip the vehicle, the spring accumulator is freed by the latching pawl 52 and the control valve 41 is operated to connect pipe 37 to pipe 27 leading to the tipping cylinders 2a, 2b.
