本发明涉及一种封堵器推送装置及封堵器输送系统,该推送装置包括推送组件和手柄。推送组件包括推送管以及可滑动的插入在推送管内部的牵引件。手柄与推送管的近端固定连接,内设有运动组件以及锁定组件;运动组件包括平移机构和旋转机构;其中,平移机构用于驱动牵引件在推送管内沿轴向运动;旋转机构用于驱动牵引件在推送管内绕轴线转动;锁定组件用于锁定牵引件与推送管的相对位置;旋转机构包括锁止结构以锁定或释放与牵引件之间的联动。本发明推送装置内设有将牵引件和推送管锁定在相对位置的锁定组件,进而在推送管推送封堵器的过程中,牵引件与推送管的相对位置将封堵器锁定在收拢的状态,从而避免封堵器未到达预定位置就提前释放。
The invention relates to a plugging device pushing device and a plugging device conveying system. The pushing device comprises a pushing assembly and a handle, where
in the pushing assembly comprises apushing pipe and a traction part slidably inserted in the pushing pipe. The handle is fixedly connected with the near end of thepushing pipe,
and a movement assembly and a locking assembly are arranged inside the handle; the movement assembly comprises a translation mechanism and a rotation mechanism;
the translationmechanism is used for driving the traction part to move along the axial direction in the pushing pipe; the rotation mechanism is used for driving the traction part to
rotate around the axis in the pushing pipe; the locking assembly is used for locking the relative positions of the traction part and the pushing pipe; and the rotation mechanism
comprises a locking structure for locking or unlocking the linkage with the traction part. According to the device and the system, thelockingassembly used for locking the
traction part and the pushing pipe at the relative positions is arranged inside the pushing device, thus in the process of pushing the plugging device by the pushingpipe,
the plugging device is locked under the closed state through the relative positions of the traction part and the pushing pipe, and therefore, the phenomenon that the
plugging device is unlocked before arriving at the preset position is avoided.
