The novel screw type hoist comprises a mounting base and a box body and further comprises an adjusting assembly, the adjusting assembly is arranged in the box body, and the adjusting assembly comprises a servo motor, a rotating shaft, an inserting block, a first bevel gear, a rotating column, a second bevel gear, a worm, a worm gear, a vertical rod, a rolling wheel, a fixing plate, a screw, a sleeve, an inserting rod and a crank. The invention belongs to the technical field of hoists, and particularly relates to a hydraulic hoist which can greatly reduce the rotating speed of a screw through meshing transmission of a small-diameter bevel gear and a large-diameter bevel gear and transmission between a worm and a worm gear, so that the situation that a valve is not easy to control due to too fast lifting is avoided. And under the condition that a servo motor is powered off, an inserting rod can still penetrate through the interior of a sleeve to be inserted into a clamping groove, lifting adjustment can be conducted on a valve, and the flexibility of overall use is guaranteed.
本发明公开的一种新型螺杆式启闭机，包括安装座和箱体，还包括调节组件，调节组件设于箱体内部，调节组件包括伺服电机、转轴、插块、锥齿轮一、转动柱、锥齿轮二、蜗杆、蜗轮、竖杆、滚轮、固定板、螺杆、套筒、插杆和摇把。本发明属于启闭机技术领域，具体是一种通过小直径锥齿轮与大直径锥齿轮的啮合传动以及蜗杆与蜗轮之间的传动可以极大的降低螺杆的转速，从而避免了阀门升降过快造成不易控制的局面，并且在伺服电机的断电的情况下仍可以通过插杆穿过套筒内部插进卡槽内部，也可以对阀门进行升降调节，保证了整体使用的灵活性的新型螺杆式启闭机。
