At this time, the power output box 2 is controlled to drive the output shaft 9 to rotate, thereby driving the material transport roller 10 to rotate to transport and lay the transverse steel bars. The longitudinal steel bars and the vertical steel bars are respectively installed through the second feeding structure and the third feeding structure, and the steel bars are assembled and the prototype of the steel bar frame is formed through the second feeding structure and the third feeding structure.

[0039] After the laying of the upper transverse steel bars is completed, the longitudinal steel bars are placed in the second installation groove 14 manually in advance. At this time, the first electric telescopic rod 15 is controlled to extend through the control console 4 to drive the lifting seat 13 and the longitudinal support frame 12 to move upward, thereby driving the longitudinal steel bars to move upward until the longitudinal steel bars and the transverse steel bars are in contact. At the same time, the stepper motor 16 is controlled to be powered on in advance to drive the threaded rod 17 to rotate, so that the mobile frame 18 and the mobile plate 19 are pulled out from the base 1.

Then, the control console 4 controls the lifting system to lift the steel bar frame, and the horizontal and longitudinal steel bars of the lower layer are laid. The welding head works here to weld the connection nodes of the lower layer to complete the welding of the steel bar frame required for the entire building wall.

[0040] See also Figure 1-Figure 8 As another preferred embodiment of the present application, the material lifting system includes a lifting plate 29, a lifting mounting plate 31, a lifting module, a third electric telescopic rod 28, a driving arm and a monitoring unit. The lifting plate 29 and the lifting mounting plate 31 are respectively movably arranged on both sides of the top seat 3, the lifting plate 29 and the lifting mounting plate 31 are connected, the third electric telescopic rod 28 is arranged on the top seat 3, and the output end of the third electric telescopic rod 28 is movably connected to the lifting plate 29 through the driving arm.

[0041] In a specific case of this embodiment, the lifting module includes a rotating shaft 34, a limiting rod 35 and a steering structure. The rotating shafts 34 are multiple in number and are symmetrically and movably arranged on the lifting mounting plate 31.

The steering structure is arranged on the lifting mounting plate 31 and connected to the rotating shaft 34, and is used to adjust the direction of the limiting rod 35.

[0042] In another specific case of this embodiment, the steering structure includes a gear 36, a rack plate 37, a fourth electric telescopic rod 38, a moving block 39 and a power arm 40.

[0044] It should be noted that the present embodiment is not limited to the above-mentioned monitoring unit to monitor the position of the lifting mounting plate 31, and an infrared ranging sensor or a laser ranging sensor may be used instead, which are not listed here one by one.

[0045] After completing the welding work on the upper connection node of the steel frame, the third electric telescopic rod 28 is controlled to contract, so that under the action of the driving arm, the lifting plate 29 and the lifting installation plate 31 are driven to move downward, and the position of the lifting plate 29 can be monitored in real time by contacting different positions on the conductive block 43 and the resistor bar 42. When the position of the lifting plate 29 moves down to the set position (that is, when the limit rod 35 just passes through the transverse steel bar), the fourth electric telescopic rod 38 can be automatically controlled by the console 4 to be energized and extended, so as to drive the moving block 39 to move downward. Under the action of the power arm 40, the rack plate 37 can be driven to move along the lifting installation plate 31. Under the meshing action between the rack plate 37 and the gear 36, the gear 36, the rotating shaft 34 and the limit rod 35 can be rotated 90°. At this time, the third electric telescopic rod 28 is controlled to extend to drive the lifting plate 29 and the lifting installation plate 31 to move upward. At this time, the limit rod 35 can be used to limit the transverse steel bars to pull up half of the steel frame, so as to prepare for the subsequent laying of the transverse and longitudinal steel bars of the lower layer.

[0046] How this application works:

[0047] The staff lays the transverse steel bars in the first installation groove 6 according to the laying density of the building wall steel bars. According to the thickness of the steel bars, the installation seat 7 and the slider 8 can adapt to steel bars of different sizes. At this time, the power output box 2 is controlled to drive the output shaft 9 to rotate, thereby driving the material conveying roller 10 to rotate to transport and lay the transverse steel bars. After the laying of the upper transverse steel bars is completed, the longitudinal steel bars are placed in the second installation groove 14 manually in advance. At this time, the console 4 controls the first electric telescopic rod 15 to extend to drive the lifting seat 13 and the longitudinal support frame 12 to move up, thereby driving the longitudinal steel bars to move up, until The longitudinal steel bars are in contact with the transverse steel bars, and the stepper motor 16 is controlled to be powered on in advance to drive the threaded rod 17 to rotate, so that the movable frame 18 and the movable plate 19 are pulled out from the base 1, and a plurality of vertical steel bars are manually laid in the third installation groove, and then the movable frame 18 and the movable plate 19 are controlled to reset. After the longitudinal steel bars are laid, the control console 4 controls the electromagnetic strips 21 to be powered on to repel each other, so that the vertical support frame 20 moves up and pushes the vertical steel bars to move up, thereby realizing the laying and connection of the vertical steel bars. Finally, the control console 4 controls the second electric telescopic rod 24 to extend to drive the push block 26 to move, and the push arm 25 is pushed up. Under the action, the welding seat 22 is driven to move up, thereby driving the bidirectional welding head 23 to move up and perform laser welding on the steel bar connection node to complete the upper layer welding work of the steel bar frame. By controlling the third electric telescopic rod 28 to contract, the lifting plate 29 and the lifting installation plate 31 are driven to move down under the action of the driving arm. Through the contact between the conductive block 43 and the different positions on the resistor bar 42, the position of the lifting plate 29 can be monitored in real time. When the position of the lifting plate 29 moves down to the set position (that is, the limit rod 35 just passes through the horizontal steel bar), the fourth electric telescopic rod 38 can be automatically controlled by the console 4 to be energized and extended, driving the moving block 3 9 moves downward, and under the action of the power arm 40, the rack plate 37 can be driven to move along the lifting installation plate 31. Under the meshing action between the rack plate 37 and the gear 36, the gear 36, the rotating shaft 34 and the limiting rod 35 can be rotated 90°. At this time, the third electric telescopic rod 28 is controlled to extend to drive the lifting plate 29 and the lifting installation plate 31 to move upward. At this time, the limiting rod 35 can be used to limit the horizontal steel bars, and half of the steel frame can be pulled up. By laying the horizontal and vertical steel bars of the lower layer, the welding work of the lower connection nodes is carried out by the welding head, and the welding work of the steel frame required for the entire building wall is completed.
