Railway ballast excavating and discharging device
The invention relates to a railway ballast excavating and discharging device, and belongs to the technical field of rail transit. The device comprises an excavating mechanism formed by a horizontal plane loop-back ballast excavating chain, a ballast discharging mechanism formed by a vertical plane loop-back ballast discharging chain, a supporting frame with a horizontal frame and an inclined lifting frame, and a frame support for fixedly connecting the supporting frame to the output end of the excavating mechanism, and the length of a ballast discharging section of the ballast discharging chain is larger than the excavating work width of the excavating mechanism. An included angle larger than 90 degrees and smaller than 120 degrees is formed between the discharging and conveying direction of the ballast discharging section and the digging and conveying direction of the digging chain along the track. By the adoption of the method, railway ballast backfilling can be effectively avoided, and good conditions are created for follow-up equipment to collect, screen, backfill and the like of the railway ballast; the discharged railway ballasts can be ensured to be accumulated in a range parallel to the outside of the track, so that the influence on the adjacent track is avoided; and finally, the railway ballast cleaning operation efficiency and quality are effectively improved.
本发明涉及一种道砟挖掘排砟装置，属于轨道交通技术领域。该装置包括水平面回环挖砟链构成的挖掘机构、垂向面回环排砟链构成的排砟机构、具有水平边框和斜升边框的支撑框架、将支撑框架固连于挖掘机构输出端的框架支撑，排砟链的排砟段长度大于挖掘机构的挖掘工作宽度，排砟段的排送方向与挖掘链沿轨道的挖送方向呈大于90°且小于120°的夹角。采用本发明可以有效避免道砟回填，为后续设备对道砟进行收集、筛分、回填等作业创造良好条件；并且可以确保排出的道砟在平行于轨道外的范围内堆积，从而避免对临线轨道的影响；最终有效提高道砟清理作业效率和质量。
