Impact type tamping trolley for railway stone ballasts
The invention belongs to the technical field of railway ballast track stone ballast tamping, and discloses a railway stone ballast impact type tamping trolley which comprises a tamping mechanism, the tamping mechanism comprises a sliding shell, a motor is fixedly connected to the side face of the sliding shell, and a gear is rotationally connected to the motor; through the cooperation of the internal combustion tamping pickaxe, the motor, the electric push rod and other structures, stone ballasts can be tamped conveniently, the internal combustion tamping pickaxe is started, the angle electric push rod and the horizontal electric push rod are started to adjust the angle of the internal combustion tamping pickaxe and the position of the pickaxe head, and meanwhile the tamping pickaxe electric push rod is started to drive the pickaxe head to tamp the stone ballasts under the sleeper; the pressure value is displayed on a control screen through a pressure sensor on the electric push rod of the internal combustion tamping pick, so that the compaction degree of ballast bed stone ballasts is determined, when the pressure value does not reach a required value, the stone ballasts under the sleeper are tamped repeatedly until the required pressure value is reached, and at the moment, the pick head is lifted through the electric push rod of the tamping pick; then the sliding shell transversely moves to the next position through rotation of the gear, then the pickaxe is put down, ballast under the sleeper is tamped, and an operator can adjust the angle of the internal combustion tamping pickaxe and the position of the pickaxe head according to the actual site situation to increase the tamping frequency of the ballast under the sleeper; and the compactness and the uniformity of the ballast bed stone ballasts after tamping and the tamping quality are well controlled.
本发明属于铁路有砟轨道石砟捣固技术领域，且公开了铁路石砟冲击式捣固小车，包括捣固机构，所述捣固机构包括滑动外壳，所述滑动外壳的侧面固定连接有电机，所述电机上转动连接有齿轮；本发明通过设置内燃捣固镐、电机、电动推杆等结构的配合，进而便利了对石砟进行捣固，启动内燃捣固镐、启动角度电动推杆和水平电动推杆来调节内燃捣固镐的角度和镐头位置同时启动捣固镐电推杆带动镐头对轨枕底下石砟进行捣固，并通过内燃捣固镐电推杆上的压力传感器将压力值在控制屏上显示，来确定道床石砟密实程度，当压力值未达到要求值时对轨枕底下石砟进行重复捣固直到达到要求压力值，这时通过捣固镐电推杆将镐头提起，随后接着通过齿轮转动使滑动外壳横向移动到下一个位置接着下镐，对轨枕底下石砟进行捣固，操作人员可以根据现场实际情况来调节内燃捣固镐的角度和镐头位置来增加对轨枕下石砟的捣固次数，使捣固后道床石砟密实度和均匀性及捣固质量很好掌控。
