[0043] like Figures 1-7 As shown, this embodiment of the invention provides a rebar lifting and shifting mechanism, including a base frame 1, an intermediate support 2, a movable body 3, a lifting support 4, a fixed grid support 5, and a positioning and fixing frame 6. The base frame 1 is located at the bottom of the entire mechanism and supports the entire structure. The intermediate support 2 is positioned above the base frame 1 and is equipped with a lifting drive device 21. The output end of the lifting drive device 21 is connected to the lifting support 4, used to lift or lower the lifting support 4. The movable body 3 is positioned on the side of the intermediate support 2 and is preferably connected to the intermediate support 2 via a slide rail slider mechanism, thereby enabling it to move horizontally on the intermediate support 2. The lifting support 4 is positioned above the intermediate support 2, and at least two fixed grid supports 5 are arranged side-by-side on the lifting support 4. Figure 4 and Figure 6 Only one fixed grid support 5 is shown in the image; preferably, multiple fixed grid supports 5 are provided in this embodiment. Each fixed grid support 5 is provided with a groove 51 for placing reinforcing bars. The fixed grid support 5 is connected to the supporting support 4 through a slide rail slider mechanism, so that it can move horizontally on the supporting support 4. The positioning and fixing frame 6 is fixed to the bottom of the fixed grid support 5 and is used to lock the position of the fixed grid support 5 on the supporting support 4. Further, the moving body 3 is provided with a lifting drive device 31. After the lifting drive device 31 lifts, it can unlock the positioning and fixing frame 6 from the supporting support 4 and drive the fixed grid support 5 to move horizontally with the moving body 3.

[0044] The rebar lifting and shifting mechanism provided in this embodiment can place multiple rebars side by side on various fixed grid supports 5. Then, the moving body 3 moves and selects a position relative to one of the fixed grid supports 5. Subsequently, the lifting drive device 31 lifts up to unlock the fixed grid support 5. At the same time, the moving body 3 moves horizontally, thereby driving the fixed grid support 5 to move horizontally on the lifting support 4, thus realizing the position adjustment of the rebar at that location. Then, the positioning and fixing frame 6 locks the position of the fixed grid support 5 on the lifting support 4 to realize the positioning of the rebar at that location. By repeating the position adjustment and positioning of other rebars, the spacing between the rebars is finally adjusted, realizing the automatic placement of rebars. In addition, this embodiment uses the lifting drive device 21 set on the intermediate support 2 to drive the lifting support 4 to rise, thereby realizing the overall lifting function of the rebars with adjusted spacing, which facilitates the subsequent processing of the rebars. This embodiment realizes the automatic adjustment of rebar spacing and the overall lifting of rebars. It has a simple structure, low manufacturing cost, is easy to maintain and repair, is convenient to use, has high work efficiency, and a high degree of automation.

[0045] Preferably, the positioning and fixing frame 6 in this embodiment includes a fixed base 61, an extension arm 62, a hinge 63, a telescopic rod 64, a rack block 65, and an elastic element 66. The fixed base 61 is fixedly connected to the bottom of the grid support 5, and a limiting plate 611 is provided on one side of the fixed base 61, with a guide hole extending through it. The extension arm 62 is rotatably mounted on the fixed base 61 via a pivot. The first end of the hinge 63 is hinged to the extension arm 62, and the second end of the hinge 63 is hinged to the rear end of the telescopic rod 64. The telescopic rod 64 is movably inserted into the guide hole on the limiting plate 611. The rack block 65 is fixed to the front end of the telescopic rod 64, and the rack block 65 has a toothed structure for engaging with the rack 41 fixed on the support bracket 4. Preferably, in this embodiment, the rack 41 can be welded to the side of the support bracket 4, the length of the rack 41 extends horizontally, and the extension direction of the telescopic rod 64 is perpendicular to the rack 41. The elastic element 66 is disposed on the telescopic rod 64. The elastic force of the elastic element 66 enables the rack block 65 to press against the rack 41 and maintain engagement with the rack 41, thereby locking the position of the grid bracket 5 on the supporting bracket 4. The positioning and fixing bracket 6 of this embodiment has a simple structure, is easy to install and use, has reliable positioning, is easy to maintain and repair, and has low cost. Preferably, in this embodiment, the elastic element 66 is a compression spring, which is disposed between the limiting plate 611 and the rack block 65.

The extension arm 62 drives the telescopic rod 64 to retract (i.e., move away from the rack 41) through the hinge 63, so that the rack block 65 disengages from the rack 41, thereby unlocking the fixed grid bracket 5 and facilitating the movement of the fixed grid bracket 5. When the lifting drive device 31 is lowered, the top plate 312 on the lifting shaft 311 falls, and the telescopic rod 64 extends towards the rack 41 under the action of the elastic member 66, so that the rack block 65 presses against the rack 41, thereby fixing the position of the fixed grid bracket 5. In this embodiment of the invention, the lifting drive device 31 can be a cylinder, a hydraulic cylinder, or an electric push rod, etc. This embodiment preferably uses a cylinder, which has a simple structure, is easy to control, and saves costs.

[0047] In this embodiment, the fixed grid support 5 is also provided with positioning holes 52. When the lifting drive device 31 is raised, the lifting shaft 311 can pass through the positioning hole 52. Thus, when the lifting drive device 31 moves horizontally with the moving body 3, it can drive the fixed grid support 5 to move together, thereby adjusting the position of the fixed grid support 5. Of course, in other embodiments, the lifting drive device 3 can also drive the fixed grid support 5 to move horizontally using a snap-fit ​​or other means, and is not limited to this embodiment. Preferably, in this embodiment, there are two sets of moving bodies 3, located on both sides of the middle support 2; at the same time, both ends of the fixed grid support 5 are provided with positioning holes 52, and the two positioning holes 52 respectively cooperate with the lifting shafts 311 on the two sets of moving bodies 3. This arrangement improves the stability and reliability of the movement of the fixed grid support 5.

This embodiment preferably uses a pneumatic cylinder, which is simple in structure, easy to control, and cost-effective. Preferably, the lifting drive device 21 in this embodiment includes two sets of large pneumatic cylinders, respectively installed at both ends of the intermediate support 2. The output ends of the two sets of large pneumatic cylinders are respectively connected to the lifting support 4, thereby improving the stability during lifting. Preferably, the intermediate support 2 is provided with a slide rail arranged vertically, and the lifting support 4 is provided with a slider, which is slidably connected to the slide rail, making the lifting / lowering movement of the lifting support 4 more stable and precise.

[0049] Furthermore, in this embodiment, a horizontally arranged slide rail is provided between the intermediate support 2 and the movable body 3, and a slider is provided for sliding engagement with it. Simultaneously, a first lead screw module 22 is installed at the middle position of the intermediate support 2. The first lead screw module 22 is connected to the movable body 3 and is used to drive the movable body 3 to move horizontally on the intermediate support 2. In this embodiment, the first lead screw module 22 may include a motor, a lead screw, a nut block, etc. The motor drives the lead screw to rotate, the lead screw drives the nut block to move horizontally, and the nut block is connected to the movable body 3, thereby driving the movable body 3 to move horizontally.

[0050] Optionally, in this embodiment, the intermediate support 2 and the base frame 1 are movably connected in the horizontal direction. Specifically, a horizontal slide rail and a slider mechanism are provided between the base frame 1 and the intermediate support 2, and a second lead screw module 11 is provided on the base frame 1.
