具体实施方式及原理：Specific implementation and principle:

在对工厂内生产好的发电机舱罩6进行转移时，将托板2先放置于转移车辆上，再通过工厂内的龙门吊将发电机舱罩6吊至托板2处并使托板2上的定位柱3插入发电机舱罩6的安装孔中，由于中间钢丝绳5未被拉直，滑动盘42在导向杆43上弹簧44弹力的作用下，滑动盘42与限位筒41顶部的盖板411内壁保持接触，同时驱动板463带动压板461转动使压板461旋转至靠近限位筒41，从而使定位柱3能够顺利插入发电机舱罩6的安装孔中，转移车辆将发电机舱罩6转运至待安装处，将托板2两侧的侧位钢丝绳21套设在吊机主体1的吊装件12左右两侧的吊钩13上，并将中间钢丝绳5套设在吊装件12下端的吊钩13上，在中间钢丝绳5被拉直的过程中会带动连接盘454上移，在连接盘454上移时，会通过驱动钢绳453带动滑动盘42向下移动，滑动盘42在向下移动的过程中通过驱动板462带动压板461朝向发电机舱罩6转动，当中间钢丝绳5被完全拉直时，此时压板461与导向杆43处于垂直状态，发电机舱罩6位于压板462与托板2之间，从而对发电机舱罩6进行限位，工人操作吊机主体1将发电机舱罩6吊至海上的发电机舱罩安装柱上。When transferring the generator cabin cover 6 produced in the factory, the pallet 2 is first placed on the transfer vehicle, and then the generator cabin cover 6 is lifted to the pallet 2 by the gantry crane in the factory and the The positioning column 3 is inserted into the installation hole of the generator cabin cover 6. Since the middle steel wire rope 5 is not straightened, the sliding plate 42 is connected to the cover plate 411 on the top of the limit cylinder 41 under the action of the elastic force of the spring 44 on the guide rod 43. The inner walls are kept in contact, and at the same time, the drive plate 463 drives the pressure plate 461 to rotate to make the pressure plate 461 rotate close to the limit cylinder 41, so that the positioning column 3 can be smoothly inserted into the installation hole of the generator cabin cover 6, and the transfer vehicle will transfer the generator cabin cover 6 to the place to be At the installation place, set the side wire ropes 21 on both sides of the supporting plate 2 on the hooks 13 on the left and right sides of the lifting part 12 of the crane main body 1, and set the middle steel wire rope 5 on the hook 13 at the lower end of the lifting part 12 When the middle wire rope 5 is straightened, it will drive the connecting plate 454 to move upward. When the connecting plate 454 moves upward, the driving steel rope 453 will drive the sliding plate 42 to move downward, and the sliding plate 42 will move downward while moving downward. During the process, the drive plate 462 drives the pressing plate 461 to rotate towards the generator cabin cover 6. When the middle wire rope 5 is completely straightened, the pressing plate 461 and the guide rod 43 are in a vertical state, and the generator cabin cover 6 is located between the pressing plate 462 and the supporting plate 2. In order to limit the position of the generator cabin cover 6, workers operate the crane main body 1 to lift the generator cabin cover 6 to the generator cabin cover installation column on the sea.

综上所述，本发明在使用时通过设置限位机构4，定位柱3插入发电机舱罩6的安装孔中，被通过托板2两侧的侧位钢丝绳21对发电机舱罩6的左右两侧进行限位，当中间钢丝绳5套设在吊钩13上被拉直时，会通过驱动钢绳453带动滑动盘42下移，在滑动盘42下移时会通过驱动板462带动压板461压向发电机舱罩6，自动对发电机舱罩6进行限位，简化了对发电机舱罩6限位过程，提高发电机舱罩6的安装效率。In summary, when the present invention is in use, by setting the limit mechanism 4, the positioning column 3 is inserted into the installation hole of the generator cabin cover 6, and the left and right sides of the generator cabin cover 6 are paired by the side wire ropes 21 on both sides of the supporting plate 2. When the middle steel wire rope 5 is set on the hook 13 and is straightened, the driving steel rope 453 will drive the sliding plate 42 to move down, and when the sliding plate 42 moves down, the driving plate 462 will drive the pressing plate 461 to press down. To the generator cabin cover 6, the generator cabin cover 6 is automatically limited, which simplifies the process of limiting the generator cabin cover 6, and improves the installation efficiency of the generator cabin cover 6.
