step three: after the supporting plate (604) is fixed, the rotating table I (603) is separated from a fixed opening on a rib plate of the supporting plate (604), the rotating table I (603) is separated from the supporting plate (604), a rotating motor (402) is connected with a power supply, an output shaft of the rotating motor (402) operates to drive a rotating rod (403) to rotate, the rotating rod (403) rotates to drive a connecting roller (404) to rotate together, a retaining ring motor (407) operates to drive a fixing buckle (406) to overturn upwards while rotating, the connecting roller (404) finishes drawing out from a notch of a suspension arm (401), when the connecting roller (404) is parallel to the suspension arm (401), the rotating motor (402) stops operating, an extension end of an ejection telescopic rod (302) is recovered, a 303) is separated from a flange plate of a steel frame, a first climbing electric wheel (201) and a secondary climbing electric wheel (202) operate downwards to drive the whole device to operate downwards, a fixed supporting mechanism (6) and a welding mechanism (8) can automatically weld the supporting plate (604) to a designated height, and an adjusting mechanism (7) can be arranged to finely adjust the position of the steel structure and install the steel structure (604) in a standard manner when the steel structure is placed;
when the device reaches a designated height, when a steel structure is required to be lifted by the lifting machine (405), if the steel structure is overweight or when the first climbing electric wheel (201) and the auxiliary climbing electric wheel (202) which are arranged are slipped, the device can slide downwards, the rotating speed measuring wheel (503) of the anti-falling speed measuring mechanism (5) is abutted to the surface of a wall or a steel frame, when the rotating speed measuring wheel (503) rubs with the wall due to the change of speed, the rotating speed measuring wheel (503) can overturn upwards, and when the speed measuring device (502) measures the speed of sliding downwards is too fast, the speed measuring device (502) transmits the measured result to the PLC (501), the PLC (501) controls the locking mechanism (3), the extension end of the ejection telescopic rod (302) is rapidly ejected, the braking plate (303) is abutted to the flange plate, the device is stopped, and the self anti-falling protection of the device is realized.
