Rotary locking hydraulic control system suitable for swing pipe excavator
The invention discloses a rotary locking hydraulic control system suitable for a swing pipe excavator. The rotary locking hydraulic control system comprises a locking mechanism, a slewing bearing, a controller and a hydraulic loop; the locking mechanism comprises a locking oil cylinder and a locking piece, and a piston rod of the locking oil cylinder is in transmission connection with the locking piece, so that the locking piece can be driven to be clamped into a tooth groove of the slewing bearing through extension of the piston rod; the hydraulic loop comprises a main oil way and a pilot oil way, a main pump and a reversing valve are arranged on the main oil way, and the main pump supplies oil to a locking oil cylinder through a reversing valve; and a pilot pump and a duplex proportional electromagnetic valve are arranged on the pilot oil way, the proportional control end of the duplex proportional electromagnetic valve is connected with the controller, a main oil inlet is connected with the pilot pump, and a working oil port is connected with a reversing control port of the reversing valve. When the hydraulic control system is located at the slope position in the construction process of a sideboom, the slewing bearing can be locked and limited, and the construction safety of the sideboom is guaranteed.
本发明公开一种适用于吊管挖掘机的回转锁紧液压控制系统，包括锁紧机构、回转支承、控制器和液压回路；所述锁紧机构包括锁紧油缸和锁紧件，锁紧油缸的活塞杆传动连接锁紧件，使得活塞杆的伸长能够带动锁紧件卡接至回转支承的齿槽内；液压回路包括主油路和先导油路，主油路上设有主泵和换向阀，主泵经换向阀向锁紧油缸供油；先导油路上设有先导泵和双联比例电磁阀，双联比例电磁阀的比例控制端连接控制器，主进油口连接先导泵，工作油口连接换向阀的换向控制口。本发明的液压控制系统在吊管机施工过程中处于斜坡位置时，能够对回转支承进行锁紧限制，保障吊管机施工安全。
