螺杆启闭机的安装步骤1、在安装螺杆启闭机时一定要保持底座基础布置平面水平180o；启闭机底座与基础布置平面的接触面积要达到90%以上；螺杆轴线要垂直闸台上衡量的水平面；要与闸板吊耳孔文和垂直，避免螺杆倾斜，造成局部受力而损坏机件。
The installation steps of screw hoist 1, installed in the screw hoist must maintain base layout level 180o; and the contact area of the base and the base closing machine layout to reach more than 90%; the screw axis to measure vertical brake bench level; and the flashboard lug Kong Wen and vertical, avoid screw tilt, cause local stress and mechanical damage.
2、将手动螺杆启闭机置于安装位置。把一个限位盘套在螺杆上，将螺杆从横梁的下部旋入机器中，当螺杆从机器的上方露出后，再套上限位盘。螺杆的下方与闸门连接。
2, manual screw hoist installed in the installation position. A limiting plate is sheathed on the screw, and the screw is screwed into the machine from the lower part of the cross beam. When the screw is exposed from the top of the machine, the upper limit plate is set. The lower part of the screw is connected with the gate.
3、对于安装启闭机的基础必须稳固安全。机座和基础构件的混凝土，按图纸的规定浇筑，在混凝土强度未达到设计强度时，不准拆除和改变启闭机的临时支撑，更不得进行试调和试运转。
3, for the installation of hoist foundation must be stable and safe. The concrete of the base and the base member shall be poured according to the provisions of the drawing, and the temporary support of the hoist is not allowed to be removed or changed when the strength of the concrete does not reach the design strength, and the trial operation shall not be carried out.
4、在安装时根据闸门起吊中心线，找正中心使纵横向中心线偏差不超过正负3mm,高程偏差不超过正负5mm。然后浇注二期混凝土或与预埋钢板连接。
4, in installation, according to the gate lifting center line, find the center, so that the vertical and horizontal center line deviation is not more than 3mm, elevation deviation is not more than 5mm. Then pouring two stage concrete or embedded steel plate connection.
5、 对于产品的电气设备的安装，一定符合图纸及说明书的规定，全部电气设备均可靠的接地。
5, for the installation of electrical equipment products, must comply with the drawings and specifications, all electrical equipment is reliable grounding.
6、 在产品安装完毕，要对机器进行清理，补修已损坏的保护油漆，灌注润滑脂。
In 6, the product is installed, to clean up the machine, repair the damaged protective paint, grease filling.
