手摇启闭机的安装步骤

Installation steps of hand-held hoist

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。

1, when installing the screw opening and closing machine, we must keep the base layout plane level 180º the contact area of the base and the basic layout plane should reach more than 90%; the axis of the screw should be vertical to the horizontal plane on the vertical sluice. A.

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, the manual screw hoist is placed in the installation position. A limiting disk is sleeved on the screw, and the screw is screwed into the machine from the lower part of the cross beam. When the screw is exposed above the machine, the upper limit disk is set. The bottom 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, the foundation must be stable and safe. The concrete of the base and the base component is put up according to the regulations of the drawings. When the strength of the concrete is not reached the strength of the design, it is not allowed to dismantle and change the temporary support of the hoist.

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, when installing, according to the lifting center line of the gate, find the center of alignment, so that the deviation between the vertical and horizontal centerlines is no more than the positive and negative 3mm, and the height deviation is no more than the positive and negative 5mm. Then the two stage concrete is poured or connected with the embedded steel plate.

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, the installation of electrical equipment must conform to the requirements of drawings and instructions, and all electrical equipment is reliable grounded.

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.

螺杆启闭机调试方法及注意事项1、当启闭机在无荷载的情况下,保证三相电流不平衡不超过正负10%，并测出电流值。

The debugging method of screw hoist and attention 1. When the hoist is in the condition of no load, the unbalanced three-phase current is not more than positive and negative 10%, and the current value is measured.

7、对于上下限位的调节：当闸门处于全闭的状态时，将上限压紧上行程开关并固定在螺杆启闭机的螺杆上。当闸门处于全开时，将下限位盘压紧下行程开关并固定在螺杆上。

7, for the upper and lower limit adjustment: when the gate is in full closed state, the upper limit will be tighten up the upper stroke switch and be fixed on the screw of the hoist. When the gate is fully open, the lower limit plate is pressed down and the switch is fixed on the screw.

8、对于启闭机的主令控制器调整，必须保证闸门升降到上、下限位时的误差不超过1cm。

8, for the adjustment of main controller of hoist, we must ensure that the error of gate lifting to upper and lower limit is not more than 1cm.

9、安装后，一定要作试运行，一作无载荷试验，即让螺杆作两个行程，听其有无异常声响，检测安装是否符合技术要求

9, after installation, we must make a trial operation, without a load test, that is, let the screw make two trips, listen to its abnormal sound, and check whether the installation meets the technical requirements.
