QL-SD double hoist double hoist screw hoist is a completely closed screw hoist, suitable for outdoor installation, self locking effect gate can stay in any position, with magnetic lock and special wrench, the body can be poured in cement, with the efficacy of anti-theft machine, double hanging point screw hoist is applied to farmland irrigation and small flood control and drainage workers. It is used for the opening and closing gates of water conservancy projects. It is a supporting machine for water construction and hydropower stations, such as water intake and retreating sluice, which can be used in mountainous areas, plain and electricity free areas. It

二、特点： 

Two. Characteristics:

LQ型螺杆式手电两用启闭机，在结构设计与使用性能上具有以下特点：

The LQ type screw type flashlight dual purpose hoist has the following characteristics in structural design and service performance.

本机为手电两用，可根据用户需要，配备电动装置，并配备摇手把，供手动使用。

This machine is dual purpose for flashlight. It can be equipped with electric device according to users' needs and equipped with hand crank for manual use.

本机设计生产执行标准为水利部、能源部SD298—88《LQ型螺杆式启闭机技术条件》。各部零件执行国家标准。

This machine is designed and manufactured as the standard for LQ screw hoist technology of Ministry of water resources and Energy Ministry SD298 - 88. The national standards for the parts of each part are carried out.

本机采用蜗轮、蜗杆变速，螺母或螺杆旋转，使闸门作上下运动，达到启（闭）闭（启）的作用。

This machine uses worm gear, worm gear, nut or screw to rotate, so that the gate moves up and down to achieve the function of opening (closing) and closing.

可根据用户要求，设磁力锁装置，以防他人开启。

According to the requirements of users, a magnetic lock device is set up to prevent others from opening.

螺杆长度可按用户要求生产，双吊点吊点距按用户要求设计。

The length of the screw can be produced according to the requirements of users. The distance between two lifting points is designed according to user requirements.

安装调试     

Installation debugging

启闭机在出厂前已加足黄油，一般在使用一段时间后，要根据情况随时加油润滑。

The hoist has been filled with butter before leaving the factory. After being used for a period of time, it should be lubricated at any time according to the situation.

2、启闭机的安装方法和一般机械相同，安装前一定要检查各部零件是否良好，螺栓有无松动与其有关技术数据是否相符。启闭机支架与基础布置平面接触面积要达到90%以上，螺杆轴线要垂直于闸台上横梁水平面，并与闸板吊耳中心重合，以免受侧向力螺杆弯曲或闸门受卡损坏机件。 

2. The installation method of the hoist is the same as that of the general machine. Before installation, it is necessary to check whether the parts of each part are good, or whether the bolt is loosened or not, and whether it is consistent with the relevant technical data. The plane contact area of the hoist frame and the base layout should be above 90%. The axis of the screw should be perpendicular to the horizontal plane of the upper beam on the gate, and coincide with the center of the sluice, so as to avoid the bending of the side force screw or the damage of the lock. It

3、启闭机安装好后，要进行试运行，先作无载荷试验，让螺杆作二个行程，听其有无异常声音，检查是否符合技术要求。二即要作载荷试验，如果新装闸门一定要将闸门的运输和装配工艺固定件拆除，试验时注意闸门有无卡死和偏起现象，如有应先行处理再试运转，在额定载荷下，让螺杆作二个行程，观察螺杆与闸门的运行情况，有无异常现象，确认无误后，方可正式运行。在载荷运行一段时间后要进行首次保养，把机内新机件摩擦产生的金属沫，特别是螺杆、螺，母、蜗轮、蜗杆，要清洗干净，涂上润滑油，继续使用。

3, after the installation of the hoist, the test run, first without load test, let the screw two trips, listen to its abnormal sound, check whether it meets the technical requirements. Two is to make a load test. If the new gate must be removed from the transport of the gate and the fixed part of the assembly process, it should be noticed whether the gate has the phenomenon of death and deviation. If there should be a trial operation, the screw will be made two strokes under the rated load, and the operation of the screw and the gate can be observed, and there is no abnormal phenomenon. When it is confirmed, it can run formally. After the load is running for a period of time, it should be maintained for the first time, and the metal foam produced by the friction of the new machine parts in the machine, especially the screw, screw, mother, worm wheel and worm, should be cleaned, coated with lubricating oil and continued to be used.
