Dynamic compaction machine rammer lowering system and control method
The invention discloses a dynamic compaction machine rammer lowering system and control method. The dynamic compaction machine rammer lowering control method comprises the steps that a transfer case is switched to be in a reverse gear according to a rammer lowering signal, and an engine is set to be in an idle speed; the descending speed of the rammer after lowering is obtained; when it is judged that the rammer is in an acceleration state according to the descending speed, an exhaust brake valve of the engine is controlled to be opened so as to increase the torque of the engine; and whether the rammer is still in an acceleration state or not after the exhaust brake valve is opened is judged, or whether the current speed of the rammer is greater than a safe speed or not is judged, if yes, the exhaust brake valve is kept open, and a brake system is started, so that the rammer is stably placed on the ground.
本发明公开了一种强夯机夯锤下放系统及其控制方法，强夯机夯锤下放控制方法包括：根据夯锤下放信号将分动箱切换为倒挡并将发动机设置为怠速；获取夯锤下放后的下降速度；当根据下降速度判断出夯锤处于加速状态时，控制发动机的排气制动阀打开，以增加发动机的转矩；判断当排气制动阀打开后夯锤是否仍处于加速状态，或夯锤的当前速度是否大于安全速度；若是，则保持排气制动阀打开，并启动刹车系统，以使夯锤平稳放置地面。
