直連式螺桿啟閉機又稱螺桿啟閉機，是一種用螺紋桿直接或通過導向滑塊、連桿與閘門門葉相連接，螺桿上下移動以啟閉閘門的機械。隨著水利水電工程的廣泛開展，用于水庫灌區河道堤壩，水力電站等工程項目上的啟閉機，閘門被大量采用。而其安裝調試技術及使用保養的知識也應大力推廣。針對建筑安裝單位和使用管理部門，應該普及此項技術與知識，方能確保工程質量，發揮工程效益。
Directly connected screw hoist, also known as screw hoist, is a mechanical device that uses a threaded rod to directly or through a guide slider or connecting rod to connect with the gate leaf, and the screw moves up and down to open and close the gate. With the widespread development of water conservancy and hydropower projects, hoists and gates used in engineering projects such as reservoir irrigation areas, river embankments, and hydropower stations are widely used. And the knowledge of installation, debugging, and maintenance should also be vigorously promoted. For construction and installation units and usage management departments, this technology and knowledge should be popularized in order to ensure project quality and maximize project benefits.
安裝調試
Installation and debugging
安裝前，一定要檢查各零件是否良好，潤滑油是否上足，螺栓有無松動，與其有關技術數據是否相符。
Before installation, it is necessary to check whether all parts are in good condition, whether the lubricating oil is sufficient, whether the bolts are loose, and whether they match the relevant technical data.
安裝時，一定要保持基礎布置槽模具 一次性止血帶 保定水處理設備 一次性止血帶 保定空壓機 北京真空泵平面水平180°;啟閉機底座與基礎布置平面的接觸面積要達到90%以上;螺桿軸線要垂直于閘臺上橫梁的水平面;要與閘板吊耳孔吻合垂直，避免螺桿傾斜，造成局部受力而損壞機件。
When installing, it is necessary to maintain the foundation layout plane level by 180 °; The contact area between the hoist base and the foundation layout plane should reach over 90%; The axis of the screw should be perpendicular to the horizontal plane of the crossbeam on the gate platform; It should be perpendicular to the lifting eye hole of the ram to avoid tilting the screw, which may cause local stress and damage the machine components.
