| 摘要 | A tippler for the discharge of rail wagons has a rail table mounted on a rotary support structure. The structure comprises spaced coaxial end frames of open arcuate form the central axis of the frames being the axis of rotation of the structure. The wagon track on the rail table has its centre line in a vertical plane at or close to said axis of rotation. A charger located alongside the tippler has a laterally extending arm and the arcuate forms of the end frames define aligned openings through which the arm passes to entrain wagons onto and from the tippler. | ||||||
| 权利要求 | 1. A rotary tippler comprising, in combination, a wagon support arrangement, spaced parallel rigid frames of open arcuate form in said support arrangement, interconnection means extending between said frames to join them rigidly and with their arcuate forms disposed about a common central axis, a wagon track having a centre line disposed in a vertical plane at or close to the common axis of said frames, a motive device disposed alongside the wagon support arrangement for loading and unloading of wagons onto and from the wagon track, engagement means on said motive device for entraining said wagons, openings in said frames defined in each frame between the ends of the frame arcuate form and said openings being in alignment providing passage for movement of said engagement means past the frames for the loading and unloading of wagons, means mounting said support arrangement rotatably about the common axis of the frames, and drive means rotating said arrangement about said axis to discharge a wagon loaded onto said track. 2. A rotary tippler according to claim 1 further comprising end stop means on at least one of said arcuate frames has adjacent the opening thereof, said end stop means limiting overrun of the rotary movement for discharging a wagon. 3. A rotary tippler according to claim 1 wherein the wagon support arrangement comprises cradle means on which said wagon track is mounted, and pivot connections between the arcuate frames and the cradle means adjacent the lower termination of the arcuate frame openings, said cradle means being pivoted about said connections with the rotation of the support arrangement to a discharge position to disPlace the wagon track towards the axis of rotation, holding means of the support arrangment for engagement with a wagon top when the cradle means is pivoted and thereby limiting said displacement of the wagon track, said holding means providing support for the wagon when the wagon is in an overturned discharged position. 4. A rotary tippler according to claim 1 wherein the support arrangement comprises wagon top holding means, mounting means locating said holding means displaceably upon the arcuate frames, control means for said displacement of the holding means bringing the holding means against the wagon top during the initial part of said rotation of the arrangement, means locking the holding means in an operative position against the wagon top to maintain engagement with the wagon top during continued rotation of the tippler to an overturned discharge position of the wagon. 5. A rotary tippler according to claim 4 wherein said locking means comprise at least one gravity-operated member disposed on a mounting displaced in said rotation of the support arrangement to bring said member to a position blocking return movement of the holding means from said operative position, means being provided in the path of said at least one locking member on the return rotation of the tippler from the discharge position while in its blocking position to displace it therefrom whereby to free the holding means from the wagon top. 6. A rotary tippler according to claim 4 wherein the or each said locking member comprises a pawl, a toothed rack fixed to said holding means being engageable by said pawl to lock the holding means in the operative position. |
