The working principle is as follows:

the first step is as follows: through the design of the alarm ball 109, the alarm ball 109 is designed to be tightly attached to the lifting rope 401, so that in the connection process of multi-hanger combined lifting of the lifting hook 402, if the lifting rope 401 is not perpendicular to the lifting rope 401, the lifting rope 401 can push the alarm ball 109 on the outer side, the alarm ball 109 can move by taking the ball connector 107 as an axis, the alarm ball 109 opposite to the inclined direction of the lifting rope 401 can be taken up by the lifting rope 401, the alarm ball 109 not opposite to the inclined direction of the lifting rope 401 can be taken up by the lifting rope 401 and then moves backwards, and in the movement, the alarm balls 109 can touch each other, so that the alarm ball 109 makes a sound, the lifting rope 401 is warned to incline for workers, and the alarm performance of the device is greatly improved.

The second step is that: when lifting rope 401 takes place the slope, just right warning ball 109 with lifting rope 401 incline direction can be taken up by lifting rope 401, because block dead plate 110 and ball type connector 107 be connected, thereby make ball type connector 107 can think and move with the opposite direction of warning ball 109, owing to the design of the position of card dead mechanism 2, thereby ball type connector 107 after the rotation can block in the clearance of card post 204, thereby take place the joint with card post 204, the dead mechanism 2 of card just can't rotate according to usual this moment, thereby after lifting rope 401 inclines to take place, the upper end of lifting rope 401 can be blocked by dead mechanism 2 extrusion joint, thereby the hoist can't carry out the work of pulling up of lifting rope 401, thereby the safety of hoist work has been guaranteed.

The third step: when the lifting rope 401 inclines, the alarm ball 109 which is not opposite to the inclination direction of the lifting rope 401 is lifted by the lifting rope 401, and then moves backwards, because the alarm ball is not opposite to the inclination direction of the lifting rope 401, the motion track of the alarm ball 109 can refer to the motion of the alarm ball 109 which is parallel to the inclination direction of the lifting rope 401, the locking plate 110 at this time can not move towards the direction of the locking mechanism 2 under the driving of the ball connector 107, but moves in the direction perpendicular to the former motion direction, at this time, through the design of the rotating ball 114, the rotating ball 114 driven by the side moving column 111 can strike the surface of the rotating plate 201, so as to drive the locking mechanism 2 to rotate by taking the rotating column 206 as an axis, so that the friction bulge 207 faces the lifting rope 401 and is in contact with the lifting rope 401, and because the surface of the friction bulge 207 is rough, the friction bulge 207 can increase the resistance of the movement of the lifting rope 401 to a certain extent, thereby assisting in making the crane unable to pull up the lifting rope 401, and further enhancing the safety performance of the crane operation.

The fourth step: through the existence of the righting mechanism 5, the righting barrel 501 is always positioned at the outer side of the alarm ball 109 for limiting the alarm ball 109 when the hook 402 is used for connecting objects, the lifting rope 401 can be touched unnecessarily when the hook 402 is used for connecting the objects, and due to the existence of the righting barrel 501, the alarm ball 109 can not be driven by the lifting rope 401 to make a sound in the connecting process of the objects, so that the alarm accuracy of the device is greatly improved.

The fifth step: after the hook 402 finishes connecting the objects, a worker of the crane starts the crane, firstly the buffer column 504 connected with the control arm 604 is pulled upwards to be lifted, the buffer column 504 is fixedly connected with the fixed column ring 505, and the fixed column ring 505 is fixedly connected with the upper edge of the upper hole 503, so the righting cylinder 501 is pulled up after the crane is started, after the righting cylinder 501 is pulled up, the alarm ball 109 loses the limit function to judge whether the lifting rope 401 is inclined, and through the design of the pulling column 506, the pulling column 506 is not completely pulled up, so the movement of the isolation plate 507 and the lifting rope 401 is not influenced completely, and through the existence of the pulling column 506, a buffer space exists between the operation of the pulling lifting rope 401 and the alarm ball 109 for warning, so that the alarm ball 109 can detect whether the lifting rope 401 is inclined between dangers, the delay functionality of the device is greatly improved.

And a sixth step: after the lifting rope 401 is detected to be inclined, firstly, the crane is placed down through the operation of workers, at the moment, the whole righting mechanism 5 can be slowly restored to the original position under the driving of the control arm 604, the lifting column 506 is restored to the contracted state, the righting cylinder 501 limits the alarm ball 109 again, so that the alarm ball 109 can be restored to the original position after being warned, the alarm ball can be righted to the periphery of the lifting rope 401 and is in contact with the lifting rope 401, the detection preparation is made after the lifting hook 402 is connected with an object again for the next time, the righting capacity of the device is greatly improved, and the device can work smoothly.

The seventh step: through the design of warning ball 109, the upper end fixed connection connecting plate 108 of warning ball 109, the upper end fixed connection ball connector 107 of connecting plate 108, ball connector 107 activity joint is in the inside of swivel ring 106, through such connection design, make warning ball 109 can rotate on the arbitrary direction that uses ball connector 107 as the axle, and through the action of gravity of warning ball 109 self, thereby make warning ball 109 have a ability that oneself resets, thereby the work of supplementary joint lifting rope 401 of finishing device that can be better, the setting of more than the structure has been avoided, great improvement the functionality of device.

Eighth step: through the existence of the protective shell 301, the alarm ball 109 can be well protected from being influenced by external wind power to generate sound through the existence of the protective shell 301, so that the alarm system of the alarm ball 109 is inaccurate, and the rigor of the overall alarm function of the device is greatly improved.

The ninth step: through the existence of protective housing 301, protective housing 301's shape includes the platykurtic, and at the in-process that wind-force blown like this, can be effectual with wind-force dispersion for two directions from top to bottom, and protective housing 301 mellow surface also can reduce wind-force to its influence to its mechanism of protection that can be fine, great improvement the life of device.

The tenth step: through the existence of the crane mechanism 6, under the control of the starter 602, three cranes are controlled to work, through the existence of the marker post 608, the rotating angle and the lifting height of the cranes can be effectively observed from the back of the cranes, the scale column 605 and the height scale 606 can be accurately read, meanwhile, the movement tracks of the three cranes can be roughly seen through the shape of the movement rope 610 by sleeving the movement rope 610 with the rope ring 609, the movement intuitiveness of the device under the work is greatly improved, and multiple hangers can be better controlled to work.
