| 摘要 | An elongated travelling grate is carried by a Support arrangement which has two transversely spaced rail units supporting the grate for movement along an endless path defined by two upper rail unit portions each having a discharge end, two lower rail unit portions each having a discharge end, two lower rail unit portions, and two at least partly curved connecting portions each of which connects one of the upper and one of the lower rail unit portions at the respective discharge end. Hydraulic pistons or the like engage the connecting portions in the region where the same join with the lower rail unit portions, so as to effect limited displacement of the connecting portions longitudinally of the grate relative to the upper and lower rail unit portions. A buffer arrangement engages the connecting portions intermediate the upper and lower rail unit portions. | ||||||
| 权利要求 | 1. In a sintering machine, a combination comprising an elongated travelling grate having a plurality of pallet means; support means including two transversely spaced rail units supporting said grate for movement along an endless path defined by two upper rail unit portions each having a discharge end, two lower rail unit portions, and two at least partly curved connecting rail portions each forming a juncture with one of said upper and one of said lower rail unit portions at the respective discharge end, said travelling grate advancing in one direction along said upper rail unit portions towards said discharge ends for travel via said connecting portions to said lower rail unit portions; displacing means engaging said connecting portions in the region of the juncture of the same with said lower rail unit portions, for effecting limited displacement of said connecting portions in longitudinal direction of said grate relative to said upper and lower unit portions; and two buffer means each engaging said connecting portions in the region adjacent said upper rail unit portions. 2. A combination as defined in claim 1, said displacing means comprising displacing elements each engaging one of said connecting portions, and a drive common to said displacing elements. 3. A combination as defined in claim 2, wherein said displacing elements are screw-spindles. 4. A combination as defined in claim 2, wherein said buffer means comprises hydraulic cylinder-and-piston units. 5. A combination as defined in claim 2, wherein said buffer means comprises spring elements. 6. A combination as defined in claim 2, wherein said buffer means comprises counterweights. 7. A combination as defined in claim 4, siad buffer means comprising at least two of said hydraulic cylinder-and-piston units each engaging one of said connecting portions, a fluid-rervoir, and conduit means connecting said hydraulic units with one another and also connecting said hydraulic units with said fluid-reservoir. 8. A combination as defined in claim 7; and further comprising throttling means interposed in said conduit means. 9. A combination as defined in claim 2; further comprising individual coupling means coupling each of said displacing elements individually and releasably with said drive. 10. A combination as defined in claim 2, said displacing elements each being displaceable between two terminal positions; and further comprising limit switch means operatively associated with said drive and said displacing elements for terminating operation of the former in response to reaching of a respective terminal position by the latter. |
