the first step is as follows: firstly, hoisting an embedded base 01 to be constructed to the inner side of a foundation pit 00 through the existing hoisting equipment, then pushing a substrate 1 manually to enable the positioning device to integrally move to the area of the foundation pit 00, enabling the embedded base 01 to enter the inner side of the leading-in inclined plane of the end part of a lower baffle frame 57 in the moving process, then continuously pushing the substrate 1 to move manually until the upper end of the embedded base 01 is abutted and contacted with the side wall of a positioning piece 571, then stopping manual pushing operation and locking a moving wheel 2, and further locking the relative position of the positioning device and the foundation pit 00;
the second step: after the relative position of the positioning device and a foundation pit 00 is locked, the embedded base 01 is positioned on the inner side of the lower stop frame 57, the clamping cylinder 577 is started to work, the triangular sliding frame 5761 is driven to slide on the fixed rod 576 through the output shaft of the clamping cylinder 577, because the side wall of the triangular sliding frame 5761 is of an inclined plane structure, in the process of linear movement of the triangular sliding frame 5761, the clamping sliding frame 575 in contact with the inclined side wall of the triangular sliding frame 5761 is pushed by the inclined plane to drive the clamping sliding rod 572 to perform displacement sliding in the left-right direction on the lower stop frame 57, the clamping ring 573 at the other end of the clamping sliding rod 572 is further close to the side wall direction of the embedded base 01, the clamping operation on the embedded base 01 is realized, the clamping spring is arranged to enable the triangular sliding frame 5761 to be tightly attached to the clamping sliding frame 575 through the self elasticity while the triangular sliding frame 5761 and the clamping sliding frame 575 relatively displaces and slides, the energy loss of the embedded base 5762 on the binding surface of the embedded base is reduced, the energy loss 574 is adjusted, and the clamping cylinder 5701 and the clamping cylinder 577 is independently controlled by the clamping cylinder 577 when the embedded cylinder 5701 and the clamping cylinder 577 is independently controlled in the clamping operation at each time;
the third step: in the process that the clamping ring 573 clamps the embedded base 01, the lifting slide bars 5732 arranged on the clamping ring 573 synchronously move close to the embedded base 01, after the clamping ring 573 primarily clamps the embedded base 01, the lifting teeth 5733 arranged at the lower end of the lifting slide bars 5732 are synchronously embedded into a steel structure at the upper end of the embedded base 01 and circumferentially abut against and support the steel structure, then the hydraulic cylinder 41 is started to work, the lifting rods 5781 are rotated through the work of the output shaft of the hydraulic cylinder 41, the lifting rotating shaft 5782 is further upwards lifted through the rotation of the lifting rods 5781, the lifting slide rings 5783 are driven to upwards move through the abutting contact action between the lifting rotating shaft 5782 and the pressure bearing rods 5784, the two groups of lifting slide bars 572 which are circumferentially arranged are further driven to synchronously upwards move through the lifting slide rings 5783, the base 01 is lifted away from the bottom of the embedded base 00 through the clamping action between the lifting teeth 5733 at the bottom of the lifting slide bars 5732 and the embedded base 01, the base 01 is further regulated in a secondary clamping operation on the embedded base 01, the inclined position of the embedded base 01, and the embedded base 01 can be prevented from being accurately positioned by the embedded base 01 in the lifting operation, and the inclined position of the embedded base 01, and the embedded base 01 can be prevented from being subjected to the inclined position of the embedded base from being regulated by the embedded base 01;
the fourth step: after the embedded base 01 is clamped, when the output shafts of the clamping cylinders 577 on the two sides of the embedded base 01 are controlled to stretch and retract in the opposite direction, the clamping rings 573 arranged at double stations can move in the left-right direction synchronously on the inner side of the lower baffle frame 57, the embedded base 01 is still in a clamping state at the moment, the embedded base 01 can be clamped and position adjustment operation of the embedded base 01 in the left-right direction in the foundation pit 00 can be realized through the synchronous movement of the double-station clamping rings 573, the anti-slip threads 5731 arranged on the inner wall of the clamping rings 573 lift contact friction force between the clamping rings 573 and the embedded base 01, and further the synchronization degree of the embedded base 01 when moving along with the clamping rings 573 is further lifted;
the fifth step: the shifting motor 56 is started to operate, the shifting rotating shaft 52 is driven to rotate by the shifting motor 56, the shifting gear 53 is driven to synchronously rotate by the shifting rotating shaft 52, in the rotating process of the shifting gear 53, the shifting slide bar 54 is driven to perform displacement sliding at the lower end of the guide ring 51 by the meshing action between the shifting gear 53 and the meshing teeth 55, the lower baffle frame 57 is further driven to perform synchronous horizontal displacement sliding by the shifting slide bar 54, and in the sliding process of the lower baffle frame 57, the embedded base 01 is pushed to synchronously move in the foundation pit 00 by the abutting contact action of the positioning sheet 571, so that the position adjustment operation of the embedded base 01 in the front-back direction is performed.
