[0008] When in use, when positioning and placing the pre-embedded steel plate bracket channel steel, place the clear wall panel on the ground, place the pre-embedded steel plate bracket channel steel on the upper wall of the clear wall panel, pick up the auxiliary shaft, and the auxiliary shaft drives the support frame to pass through the hole of the pre-embedded steel plate bracket channel steel and contact the upper wall of the clear wall panel. The support frame is used to support the auxiliary shaft. The top plate of the pre-embedded steel plate bracket channel steel is horizontally arranged in the middle part of the clamping groove. The locking electromagnet is energized to generate magnetism. The locking electromagnet is set with the same pole as the magnetic strip. The locking electromagnet is connected to the magnetic port through the magnetic guide port. The magnetic field is conducted between the magnetic strips, and the magnetic strips are fixed on the side wall of the auxiliary shaft and use the deformation of the clamping spring to push the locking electromagnet. The locking electromagnet drives the clamping block to slide along the locking groove, and the clamping block slides out of the locking groove. The clamping block drives the clamping groove to support the top plate of the embedded steel plate bracket channel steel. The connecting shaft is inserted into the interior of the cleaning plate, and the auxiliary shaft is lifted. The auxiliary shaft drives the embedded steel plate bracket channel steel to separate from the upper wall of the cleaning plate through the clamping block. The cleaning plate is picked up and inserted into the outside of the connecting shaft, and the connecting nut is screwed into the outside of the connecting shaft. The cleaning wall plate is fixed on the outside of the connecting shaft. The lifting slider slides down along the auxiliary shaft under the weight of the embedded steel plate bracket channel steel by the deformation of the lifting spring, and the auxiliary shaft is lifted to drive the support frame into the reserved concrete foundation pit. The bottom wall of the support frame fits with the bottom wall of the foundation pit. Due to the uneven side wall of the foundation pit, the embedded steel plate bracket channel steel cannot completely enter its interior. At this time, the driving electromagnets at both ends of the auxiliary shaft are energized to generate magnetism. The driving electromagnets at both ends of the auxiliary shaft are set with different poles, and the bottom of the auxiliary shaft is The driving electromagnet of the wall and the sliding magnet of the bottom wall of the lifting slider are set with the same pole, and the driving electromagnet on the upper wall of the auxiliary shaft and the sliding magnet on the upper wall of the lifting slider are set with different poles. The lifting slider uses the deformation of the lifting spring to rise along the auxiliary shaft under the action of the magnetic field of the sliding magnet and the driving electromagnet. The driving electromagnet is powered off and demagnetized, and the embedded steel plate bracket channel drives the wall cleaning plate to fall freely. The wall cleaning plate eliminates the protrusions on the inner wall of the foundation pit, ensuring that the embedded steel plate bracket channel is installed unobstructed inside the concrete foundation pit.

[0010] When in use, after the cleaning wall plate clears the raised blocks on the inner wall of the reserved concrete foundation pit, the raised blocks fall into 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 is energized again to generate magnetism. Under the action of the sliding magnet and the driving electromagnet magnetic field, the lifting slider uses the deformation of the lifting spring to drive the embedded steel plate bracket channel steel to rise, and the driving electromagnet is powered off and demagnetized. The embedded steel plate bracket channel steel drives the cleaning wall plate to fall freely. The cleaning wall plate crushes the concrete raised blocks at the bottom of the foundation pit. Under the action of multiple uses of the cleaning wall plate to squeeze the raised blocks, the raised blocks accumulated at the bottom of the foundation pit are squeezed into powder, and the locking nut is rotated. The locking nut rotates along the rotating block away from the upper wall of the auxiliary shaft, and the rotating block changes from a fixed state to a In the active state, the pitch-adjusting nut is rotated, and the pitch-adjusting nut moves toward the end of the dust extraction tube away from the rotating block, pressing the dust extraction tube, and the dust extraction tube drives the dust extraction port and the dust sweeping soft bristles to extend out of the dust suction channel. The wall cleaning plate is maintained above the bottom wall of the foundation pit under the elastic support of the lifting spring, and the rotating wheel is rotated. The rotating wheel drives the dust extraction tube through the rotating block, and the dust extraction tube cleans the crushed raised blocks at the bottom of the foundation pit through the dust sweeping soft bristles. The powder at the bottom of the foundation pit floats under the cleaning of the dust sweeping soft bristles, and the suction end of the external air pump is connected with the end of the dust extraction tube that passes through the rotating block. The external air pump sucks the powder into the dust extraction tube through the dust extraction port, and 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;

[0011] After the bottom of the foundation pit is cleaned, pull the dust extraction pipe, and the dust extraction pipe drives the dust extraction port and the dust sweeping bristles to retract into the dust suction channel, rotate the distance adjusting nut, and the distance adjusting nut rotates along the dust extraction pipe and fits the upper wall of the rotating block, rotate the locking nut, and the locking nut descends along the rotating block and fits the upper wall of the auxiliary shaft, and the rotating block changes to a fixed state, and the driving electromagnet is energized to generate magnetism. The lifting slider rises under the action of the sliding magnet and the driving electromagnet's magnetic field, and the connecting nut is rotated and unscrewed from the outside of the connecting shaft to remove the wall cleaning plate from the outside of the connecting shaft. , the driving electromagnet is powered off and demagnetized, and the embedded steel plate corbel channel drives the lifting slide block to fall freely into the foundation pit, the magnetic pole of the locking electromagnet changes, and the locking electromagnet attracts the magnetic strip through magnetic force, and the locking electromagnet drives the clamping block to retract into the locking groove, and the clamping block drives the clamping groove away from the top plate of the embedded steel plate corbel channel. At this time, the embedded steel plate corbel channel falls into the interior of the foundation pit, and the auxiliary shaft is picked up by the rotating wheel. The auxiliary shaft drives the support frame to be pulled out from the interior of the embedded steel plate corbel channel to complete the positioning and installation of the embedded steel plate corbel channel.

[0012] The beneficial effects achieved by adopting the above structure are as follows:

[0013] Compared with the existing technology, this solution adopts a combination of a self-weight obstacle sweeping structure and an obstacle collection structure. Through the heavy-pressure obstacle clearing mechanism and the pressure-type cleaning mechanism, the lifting mechanism, the leg locking mechanism, the linkage mechanism, the wall cleaning mechanism, the dust-floating mechanism and the distance-adjusting mechanism cooperate with each other to eliminate the raised blocks on the inner wall of the concrete foundation pit that cause obstructions during the installation of the pre-embedded steel plate corbel channel steel, and can repeatedly roll the concrete raised blocks that fall from the inner wall of the foundation pit to the bottom wall of the foundation pit to change them into powder. Under the cleaning of the dust-sweeping soft hair, the impurities at the bottom of the foundation pit are removed by an external vacuum pump, thereby ensuring the stability of the pre-embedded steel plate corbel channel steel after positioning and installation, and to a certain extent improving the efficiency of the auxiliary positioning of the pre-embedded steel plate corbel channel steel.

[0031] During specific use, in the initial state, the lifting slider 5 is located at the end of the auxiliary shaft 1 away from the support frame 2, the linkage slider 18 drives the linkage column 19 to be retracted and placed inside the auxiliary shaft 1, and the clearing wall plate 23 is arranged away from the connecting shaft 21. When installing the pre-embedded steel plate corbel channel steel, the raised concrete blocks left on the inner wall of the reserved concrete foundation pit will hinder the entry of the pre-embedded steel plate corbel channel steel. In order to avoid the pre-embedded steel plate corbel channel steel from being offset during installation inside the foundation pit, the diameter of the foundation pit is generally consistent with the diameter of the bottom plate of the pre-embedded steel plate corbel channel steel, thereby preventing the pre-embedded steel plate corbel channel steel from deviating from the center point position inside the foundation pit;

[0032] When positioning and placing the pre-embedded steel plate bracket channel steel, place the clearing wall plate 23 on the ground, the pre-embedded steel plate bracket channel steel is placed 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 pass through the hole of the pre-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 pre-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 set with the same pole. The locking electromagnet 15 conducts the magnetic field between the magnetic guide port 12 and the magnetic strip 10. The magnetic strip 10 is fixed to the side wall of the auxiliary shaft 1 and uses the deformation of the clamping spring 35 to push the locking electromagnet 15. The locking electromagnet 15 drives the clamp The holding block 13 slides along the locking groove 11, and the clamping block 13 slides out of the locking groove 11. The clamping block 13 drives the clamping groove 14 to support the top plate of the embedded steel plate bracket channel steel, and the connecting shaft 21 is inserted into the cleaning wall plate 23. The auxiliary shaft 1 is lifted, and the auxiliary shaft 1 drives the embedded steel plate bracket channel steel to separate from the upper wall of the cleaning wall plate 23 through the clamping block 13. The cleaning wall plate 23 is picked up and inserted into the outer side of the connecting shaft 21, and the connecting nut 24 is screwed into the outer side of the connecting shaft 21. The cleaning wall plate 23 is fixed to the outer side of the connecting shaft 21. The lifting slide block 5 slides and descends along the auxiliary shaft 1 under the weight of the embedded steel plate bracket channel steel using the deformation of the lifting spring 6. The auxiliary shaft 1 is lifted to drive the support frame 2 to enter the reserved concrete foundation pit, and the bottom wall of the support frame 2 fits with the bottom wall of the foundation pit;

[0033] Due to the uneven side wall of the foundation pit, the embedded steel plate bracket channel steel cannot completely enter the interior thereof. At this time, the driving electromagnets 8 at both ends of the auxiliary shaft 1 are started, and the driving electromagnets 8 are energized to generate magnetism. The driving electromagnets 8 at both ends of the auxiliary shaft 1 are set with different poles. The driving electromagnets 8 on the bottom wall of the auxiliary shaft 1 and the sliding magnets 7 on the bottom wall of the lifting slider 5 are set with the same poles. The driving electromagnets 8 on the upper wall of the auxiliary shaft 1 and the sliding magnets 7 on the upper wall of the lifting slider 5 are set with different poles. The lifting slider 5 utilizes the deformation of the lifting spring 6 to rise along the auxiliary shaft 1 under the action of the magnetic fields of the sliding magnet 7 and the driving electromagnet 8. The driving electromagnet 8 is powered off and demagnetized, and the embedded steel plate bracket channel steel drives the cleaning plate 23 to fall freely. The cleaning plate 23 eliminates the protrusions on the inner wall of the foundation pit, ensuring that the embedded steel plate bracket channel steel is installed into the concrete foundation pit without hindrance.

[0034] After the cleaning wall plate 23 clears the raised blocks on the inner wall of the reserved concrete foundation pit, the raised blocks fall into the bottom of the foundation pit, which will cause the embedded steel plate bracket channel steel to be 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. The driving electromagnet 8 is powered off and demagnetized, and the embedded steel plate bracket channel steel drives the cleaning wall plate 23 to fall freely. The cleaning wall plate 23 crushes the concrete raised blocks at the bottom of the foundation pit. Under the action of the cleaning wall plate 23 squeezing the raised blocks for multiple times, the raised blocks accumulated at the bottom of the foundation pit are squeezed into powder.

[0035] The locking nut 29 is rotated and the locking nut 29 rotates along the rotating block 27 away from the upper wall of the auxiliary shaft 1. The rotating block 27 changes from a fixed state to a movable state. The adjusting nut 36 is rotated and the adjusting nut 36 moves toward the end of the dust extraction pipe 32 away from the rotating block 27. The dust extraction pipe 32 is pressed, and the dust extraction pipe 32 drives the dust extraction port 33 and the dust sweeping soft bristles 34 to extend out of the dust suction channel 31. The wall cleaning plate 23 is kept above the bottom wall of the foundation pit under the elastic support of the lifting spring 6. The rotating wheel 28 is rotated and the rotating wheel 28 drives the rotating block 27 to rotate. The dust extraction pipe 32 cleans the crushed raised blocks at the bottom of the foundation pit through the dust sweeping soft bristles 34. The powder at the bottom of the foundation pit floats under the cleaning of the dust sweeping soft bristles 34. The suction end of the external air pump is connected to the 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 extraction 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;

[0036] 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 cleaning bristles 34 to retract into the dust suction channel 31. The pitch adjusting nut 36 is rotated, and the pitch adjusting nut 36 rotates along the dust extraction pipe 32 and fits the upper wall of the rotating block 27. The locking nut 29 is rotated, and the locking nut 29 descends along the rotating block 27 and fits the upper wall of the auxiliary shaft 1. The rotating block 27 changes to a fixed state, and the driving electromagnet 8 is energized to generate magnetism. The lifting slide 5 rises under the action of the magnetic fields of the sliding magnet 7 and the driving electromagnet 8. The connecting nut 24 is rotated and unscrewed from the outer side of the connecting shaft 21, and the wall cleaning plate 23 is removed from the outer side of the connecting shaft 21.

[0037] The driving electromagnet 8 is powered off and demagnetized, and the embedded steel plate corbel channel steel drives the lifting slider 5 to freely fall into the interior of the foundation pit, and the magnetic pole of the locking electromagnet 15 changes. The locking electromagnet 15 attracts the magnetic strip 10 through magnetic force, and the locking electromagnet 15 drives the clamping block 13 to retract into the locking groove 11. The clamping block 13 drives the clamping groove 14 away from the top plate of the embedded steel plate corbel channel steel. At this time, the embedded steel plate corbel channel steel falls into the interior of the foundation pit, and the auxiliary shaft 1 is picked up by the rotating wheel 28. The auxiliary shaft 1 drives the support frame 2 to be pulled out from the interior of the embedded steel plate corbel channel steel, completing the positioning and installation of the embedded steel plate corbel channel steel; repeat the above operation when using it next time.
