At this time, the driving electromagnet is energized again to generate magnetism. Under the action of the sliding magnet and the driving electromagnet magnetic field, the lifting slide block uses the deformation of the lifting spring to drive the embedded steel plate bracket channel steel to rise, the driving electromagnet is powered off and demagnetized, and the embedded steel plate bracket channel steel drives the wall cleaning plate to fall freely.

When the embedded steel plate corbel channel steel is installed, the raised concrete blocks left on the inner wall of the reserved concrete foundation pit will hinder the entry of the embedded steel plate corbel channel steel. In order to avoid the embedded steel plate corbel channel steel being installed at a position offset inside the foundation pit, the diameter of the foundation pit is generally consistent with the diameter of the bottom plate of the embedded steel plate corbel channel steel, thereby avoiding the embedded steel plate corbel channel steel from offsetting the center point position inside the foundation pit; When positioning and placing the embedded steel plate bracket channel steel, place the clearing wall plate 23 on the ground, place the embedded steel plate bracket channel steel on the upper wall of the clearing wall plate 23, pick up the auxiliary shaft 1, and the auxiliary shaft 1 drives the support frame 2 to penetrate the hole of the embedded steel plate bracket channel steel and contact the upper wall of the clearing wall plate 23. The support frame 2 is used to support the auxiliary shaft 1. The top plate of the embedded steel plate bracket channel steel is horizontally arranged in the middle part of the clamping groove 14. The locking electromagnet 15 is started, and the locking electromagnet 15 is energized to generate magnetism. The locking electromagnet 15 and the magnetic strip 10 are arranged with the same pole. The locking electromagnet 15 conducts the magnetic field between the magnetic guide port 12 and the magnetic strip 10.

After the cleaning plate 23 removes the raised blocks on the inner wall of the reserved concrete foundation pit, the raised blocks fall to the bottom of the foundation pit, which will make the embedded steel plate bracket channel steel uneven after installation, thereby reducing the stability of the embedded steel plate bracket channel steel. At this time, the driving electromagnet 8 is started again, and the driving electromagnet 8 is energized to generate magnetism. Under the action of the magnetic fields of the sliding magnet 7 and the driving electromagnet 8, the lifting slider 5 uses the deformation of the lifting spring 6 to drive the embedded steel plate bracket channel steel to rise, and the driving electromagnet 8 is powered off and demagnetized.

The suction end of the external air pump is connected to one end of the dust extraction pipe 32 that passes through the rotating block 27. The external air pump sucks the powder into the dust extraction pipe 32 through the dust suction port 33. Finally, the powder is discharged from the external air pump, thereby completing the cleaning of impurities at the bottom of the foundation pit, ensuring the flatness of the installation of the embedded steel plate bracket channel steel, and improving the auxiliary positioning efficiency of the embedded steel plate bracket channel steel; After the bottom of the foundation pit is cleaned, the dust extraction pipe 32 is pulled, and the dust extraction pipe 32 drives the dust extraction port 33 and the dust sweeping soft bristles 34 to retract into the dust suction channel 31, and the distance adjusting nut 36 is rotated, and the distance adjusting nut 36 rotates along the dust extraction pipe 32 and fits the upper wall of the rotating block 27, and the locking distance nut 29 is rotated, and the locking distance nut 29 descends along the rotating block 27 and fits the upper wall of the auxiliary shaft 1, and the rotating block 27 changes to a fixed state, and the driving electromagnet 8 is energized to generate magnetism, and the lifting slide block 5 rises under the action of the magnetic fields of the sliding magnet 7 and the driving electromagnet 8, and the connecting nut 24 is rotated, and the connecting nut 24 is unscrewed from the outer side of the connecting shaft 21, and the wall cleaning plate 23 is taken down from the outer side of the connecting shaft 21; The driving electromagnet 8 is powered off and demagnetized, and the embedded steel plate corbel channel steel drives the lifting slide block 5 to freely fall into the foundation pit, and the magnetic pole of the locking electromagnet 15 changes.
