[0034] like Figures 1 to 5 As shown, the utility model provides a stirrup stacking device, which includes a fixed frame 1, a rotating support rod 2 and a spreading drive member 5. The fixed frame 1 is movably arranged on an external mounting position; the first ends of the two rotating support rods 2 are transferred to the fixed frame 1 at intervals, and the second ends of the two rotating support rods 2 extend in a direction away from the fixed frame 1. Each rotating support rod 2 is provided with a fixing portion 3, which is used to fix two opposite long sides of the stirrup 200; the output end of the spreading drive member 5 is connected to the rotating support rod 2 to drive the second ends of the two rotating support rods 2 to move closer to or away from each other.

[0035] When the stirrup 200 is bent, the two opposite long sides of the stirrup 200 can be fixed by the fixing part 3 provided on the rotating support rod 2, and the driving member 5 is opened to drive the second ends of the two rotating support rods 2 away, thereby stretching the stirrup 200 and placing it on the single-piece net 100, and then driving the second ends of the rotating support rods 2 closer to restore the stirrup 200 to its original shape, so that the stirrup 200 is placed on the single-piece net 100.

[0036] In some embodiments, after the long steel bars are formed into stirrups 200, the stirrups 200 are in a horizontal state, that is, the long sides of the stirrups 200 are in a horizontal direction. However, when the stirrups 200 are stacked, the long sides of the stirrups 200 need to be placed in a vertical state on the single-piece net 100. Based on this, when the stirrup stacking device clamps the stirrups 200, the fixing frame 1 needs to be flipped relative to the external mounting portion, so that the rotating support rod 2 is flipped in the horizontal and vertical directions; specifically, as shown in FIG. Figures 1 to 5 As shown, the stirrup stacking equipment further includes a flipping drive 4, which is disposed on an external mounting portion. The fixed frame 1 is disposed at the output end of the flipping drive 4. The flipping drive 4 then drives the fixed frame 1 to flip, causing the rotating support rod 2 to receive the stirrup 200 in a horizontal state. The rotating support rod 2 is then flipped downward to a vertical state, allowing the stirrup 200 to be opened in the vertical state and placed on the single-sheet net 100. Specifically, the flipping drive 4 is a rotary motor, the output end of which is provided with a rotary shaft 41. The fixed frame 1 is fixed to the rotary shaft 41 by welding or bolts. The rotary motor then drives the fixed frame 1 to flip relative to the external mounting portion to perform the operations of removing and placing the stirrup 200.

[0037] like Figure 3 and Figure 4 As shown, in order to facilitate the fixing of the long side of the stirrup 200, in some embodiments, the fixing portion 3 includes a limit block 31 and a fixed driving member 32. A plurality of limit blocks 31 are arranged at intervals along the length direction of the rotating support rod 2. The limit blocks 31 are L-shaped. Each limit block 31 corresponds to a fixed driving member 32. The fixed driving member 32 is arranged opposite to the limit block 31. A clamping plate 33 is provided at the output end of the fixed driving member 32. The fixed driving member 32 can drive the clamping plate 33 to move closer to or away from the limit block 31 to clamp or release the long side of the stirrup 200. Furthermore, in order to ensure stable clamping, a limiting notch 34 is provided on one side of the limit block 31 facing the clamping plate 33 and / or on one side of the clamping plate 33 facing the limit block 31. Therefore, when the limit block 31 contacts the clamping plate 33, a limiting space is formed to confine the stirrup 200 therein.

[0038] like Figure 1 and Figure 2As shown, in some embodiments, an expansion drive 5 is disposed on a fixed frame 1. A rotating plate 6 is disposed at the output end of the expansion drive 5. The expansion drive 5 drives the rotating plate 6 to rotate. The two ends of the rotating plate 6 are respectively rotatably connected to one end of two first connecting plates 7. The other ends of the two first connecting plates 7 are rotatably connected to one end of two second connecting plates 8. The other ends of the two second connecting plates 8 are respectively connected to the first ends of two rotating support rods 2. The middle portion of the second connecting plate 8 is connected to the fixed frame 1. Thus, the first connecting plates 7 and the second connecting plates 8 form a connecting rod group, and the rotation of the rotating plate 6 drives the expansion or closing of the rotating support rods 2. For example, the expansion drive 5 can be, but is not limited to, a rotary cylinder or a rotary motor. The above method can achieve the opening and closing of the second end of the rotating support rod 2 by controlling the first end of the rotating support rod 2, thereby avoiding unnecessary interference with the stirrups 200 when receiving or placing the stirrups 200. At the same time, the above structure can also minimize the opening angle of the first end of the rotating support rod 2 to avoid affecting the short side of the stirrups 200. It is understandable that in other alternative embodiments, the connecting rod group formed by the first connecting plate 7 and the second connecting plate 8 can also be replaced by other means such as chain transmission, gear transmission or belt transmission.

[0039] In some embodiments, in order to facilitate the stacking of stirrups 200 on the single-piece net 100 and ensure the stability of the stirrups 200 during the flipping and placement of the fixed frame 1, the stirrup stacking equipment also includes a telescopic drive member 9, which is arranged on the fixed frame 1 and is located between the first ends of the two rotating support rods 2. The output end of the telescopic drive member 9 is provided with a holder 91, and a slot 92 is provided on the holder 91. The slot direction of the slot 92 is perpendicular to the extension direction of the rotating support rod 2. The holder 91 can clamp the short side of the stirrup 200 through the slot 92. The telescopic drive member 9 can drive the holder 91 close to or away from the second end of the rotating support rod 2. When the stirrup 200 is placed on the single-piece net 100 after opening, the telescopic drive member 9 drives the holder 91 close to the second end of the rotating support rod 2, thereby causing the stirrup 200 to slide along the rotating support rod 2 to completely fit the stirrup 200 with the single-piece net 100, and then perform the welding operation. For example, the telescopic driving member 9 may be, but is not limited to, a cylinder or a motor.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the stirrup stacking equipment also includes a rotating drive member 10, which is arranged on an external mounting portion. A rotating plate 101 is provided at the output end of the rotating drive member 10. The rotating drive member 10 drives the rotating plate 101 to rotate relative to the external mounting portion, and the flipping drive member 4 is provided on the rotating plate 101, and then the angle of the rotating support rod 2 is adjusted by the rotation of the rotating plate 101, and then the stacking angle of the stirrups 200 is adjusted to adapt to the single-piece net 100 in different positions.

[0041] The present invention also provides a stirrup welding system, which includes a frame and the stirrup stacking equipment and welding device. The fixed frame 1 is movably arranged on the frame, and the welding device is also arranged on the frame; illustratively, the welding device may include a manipulator and a welding head arranged on the manipulator, so that the stirrups 200 stacked by the stirrup stacking equipment can be welded to the single-piece mesh 100.

[0042] Here are the steps in brief:

[0043] After the cam 200 is closed, welding is performed. After the welding is completed, the fixed driving member 32 drives the card plate 33 to disengage from the limit block 31, and then the flip driving member 4 drives the fixed frame 1 to flip in the opposite direction and disengage from the stirrup 200.

[0044] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
