It is not convenient to adjust the force balance of the steel wire rope and adjust the steel wire rope suspension points to improve the safety of the steel wire rope. At the same time, it is not convenient to automatically detect the stability of the platform and automatically control the platform recovery. There is a risk of falling from a high altitude when the platform is overloaded and tilted. The safety is poor and it is not convenient to remind staff of platform abnormalities.

[0025] On the basis of the above, the material discharge guide part 5 includes a rotating gathering plate 501 and a supporting threaded rod 502. The rotating gathering plate 501 is rotatably installed on the mobile platform plate 401. Two supporting threaded rods 502 are threadedly connected to the rotating gathering plate 501. The two supporting threaded rods 502 are respectively provided with hand wheels. The two supporting threaded rods 502 are used to support the rotating gathering plate 501 to tilt. The two supporting threaded rods 502 pass through the rotating gathering plate 501 respectively; the material discharge guide part 5 is used to simply control and adapt to the switching of different cargo unloading tasks, and realize the unloading of materials such as plates in a flat state. At the same time, the rotating rotating gathering plate 501 can be used to limit steel pipe materials after tilting to avoid material movement. At the same time, the materials are also gathered in the middle of the fixed cantilever frame 101, which improves the balance stability, is safer, simple and convenient to operate, and flexible to use.

[0026] The working principle of this embodiment is as follows: The pre-buried steel bars for installing the auxiliary traction rope 103 are set on the outer wall of the building, and bolts are inserted into the two rows of through holes provided on the fixed cantilever frame 101. The fixed cantilever frame 101 is installed on the building floor by means of bolts. The side of the limit block 104 is fitted on the window side of the building and installed with bolts. One end of the two auxiliary traction ropes 103 is connected to the pre-buried steel bars on the outer wall of the building, and the existing steel wire rope buckles and other parts are used for installation. At the same time, bolts are inserted into the two rows of through holes in the suspension anchor plate 601 to install it on the building floor. The two auxiliary traction ropes 103 play the role of traction insurance and are also connected to the outer wall of the building to complete the structure. The main rope 602 is fixed on the base and the main rope 602 is fixed on the base. When the suspension anchor plate 601 is installed, the cantilever frame 101 is fixed under the action of gravity and naturally drives the main rope sheave 102 to press the main steel wire rope 602 downward. At this time, the main steel wire rope 602 adapts to the position of the main rope sheave 102 and cooperates with the suspension traction of the main steel wire rope 602. The main steel wire ropes 602 on both sides of the main rope sheave 102 are subjected to the same force. There is no need to perform tedious measurement and adjustment when installing the two main steel wire ropes 602 as in the traditional technology. At this time, the positioning bolts 702 can be tightened to position the main steel wire rope 602, and the rotating gathering plate 501 can be supported by rotating the supporting threaded rod 502. At this time, the two rotating gathering plates 501 are in an inclined state, that is, It can be used to fix steel pipes and other heavy goods that are easy to move. When the fixed cantilever frame 101 is pressed down or loosened by overload gravity, the fixed cantilever frame 101 will produce a certain bending deformation, and the fixed cantilever frame 101 will drive the downward pressure detection head 302 on the detection mounting frame 301 to press down the lifting connection column 204. At this time, the lifting connection column 204 squeezes the micro switch 203, and the micro switch 203 lights up the alarm light pole 105 to alarm. At the same time, if the fixed cantilever frame 101 is affected by factors such as wind and has a large lateral swing, it can drive the downward pressure detection head 302 on the detection mounting frame 301 to move lateral. At this time, the downward pressure detection head 302 lateral squeezes the lifting connection column 204. The top of the connecting column 204; the detection head 302 is pressed down to move downward, and the micro switch 203 is squeezed, and the alarm light pole 105 is controlled to light up and alarm again to remind the workers that an abnormality has occurred; when the micro switch 203 is pressed, the driving motor 402 is controlled at the same time, and the driving threaded rod 403 is controlled to rotate, and the threaded connecting frame 106 is cooperated with the threaded connecting frame 106 to drive the threaded rod 403 to rotate, driving the mobile platform plate 401 to slide on the fixed cantilever frame 101 through the roller 4011, driving the mobile platform plate 401 to move into the interior of the building, reducing the gravity on the fixed cantilever frame 101, and avoiding the safety hazards caused by the falling off of the fixed cantilever frame 101 and the suspension connector 6.

[0027] When it is necessary to adjust the stress point of the main wire rope 602, ensure that there is no cargo load on the mobile platform part 4, loosen the two positioning bolts 702, and use the wrench to control the switching control screw rod 604 to rotate, driving the rope slider 603 to move. At this time, the rope slider 603 drives the main wire rope 602 to move on the main rope sheave 102 to switch the position of the main wire rope 602 corresponding to the main rope sheave 102, avoiding the main wire rope 602 from being locally subjected to stress at the main rope sheave 102 for a long time, resulting in a reduction in strength, thereby achieving the purpose of adjusting the stress point of the main wire rope 602.
