Types and structural characteristics of hoist

启闭机用于各类大型给排水、水利水电工程。用于控制各类大、中型铸铁闸门及钢制闸门的升降达到开启与关闭的目的。按类型分为：液压启闭机，卷扬启闭机，门机，手轮启闭机，手摇启闭机，螺杆式启闭机等。 

Headstock gear is used for all kinds of large water supply and drainage, water conservancy and hydropower projects. It is used to control the lifting of various large and medium cast iron gates and steel gates to achieve the purpose of opening and closing. According to the type is divided into: hydraulic hoist, winch hoist, door machine, hand wheel hoist, hand shake hoist, screw hoist and so on.  

结构特点

Structural characteristics

1、启闭机包括电机、启闭机、机架、防护罩等组成；采用三级减速方式，用国旋付传动，输出转距更大。启闭机配套钢架克服土建不平整，以减少整机噪声及振动。

1. The hoist consists of motor, hoist, rack, protective cover, etc. It adopts three-stage deceleration mode and uses national spinning pair to drive, and the output torque is larger. The hoisting machine supporting steel frame overcomes the unevenness of the civil construction, so as to reduce the noise and vibration of the whole machine.

2、采用户外型长时工作制电机，防护等级≥IP155。行程控制机构采用十进制计数器原理，控制行程的误差0.5%。转距保护控制是通过蜗杆产生轴向位移触动微动开关，来达到保护电器的原理。3、操作维  护简便，可实现现场和远控操作。

2, adopt outdoor long time working motor, the protection level is more than IP155. The travel control mechanism adopts the decimal counter principle to control the error of the stroke 0.5%. The pitch protection control is to achieve the principle of protecting the electrical appliances by triggering the micro-switch with the axial displacement generated by the worm. 3, operation and maintenance is simple, and can realize on-site and remote control operation.

主要由卷扬机构、钢丝绳、抓斗、钢丝绳滑轮、抓斗张合装置、机械过力矩保护、移动行车、地面固定式轨道及移动行车定位装置组成。整机定位清污动作、抓斗升降、抓斗张合。其工作原理为：除污时，通过行程开关控制，使机架移动到需清污的格栅位置，当上下机架对位准确后，抓斗才可顺利下放除污。对于宽幅格栅，除污机除污完毕移动一个抓斗有效宽度，继续除污，直至格栅栅面污物清除完毕，栅前后水位差达到正常值时为止。对于多沟渠分布格栅，除污机除污完一个沟渠的格栅后，移动至另一沟渠，继续除污，直至所有沟渠格栅栅面污物清除完毕，栅前后水位差达到正常值时为止。

It is mainly composed of hoisting mechanism, wire rope, grab, wire rope pulley, grab tensioning and closing device, mechanical torque protection, mobile driving, ground fixed track and mobile positioning device. The whole machine is positioned for cleaning action, grab lifting and grab lifting. Its working principle is: in the process of decontamination, the rack is moved to the grille position which needs to be decontaminated by the stroke switch control. When the upper and lower racks are aligned accurately, the grab can be lowered smoothly to decontaminate. For the wide grille, the decontaminator moves a grab effective width after decontamination and continues to decontaminate until the grille surface is decontaminated and the water level difference between the front and back of the grille reaches the normal value. For multi-channel grille, the decontaminator moves to another channel after decontaminating one channel grille, and continues to decontaminate until all the grille surface dirt is removed and the water level difference between the front and back of the grille reaches the normal value.
