[0056] The present application first provides a T-beam top plate single stirrup welding forming method, as shown in the figure, the single stirrup includes a main stirrup 200 and a plurality of auxiliary stirrups 300, the plurality of auxiliary stirrups 300 are spaced apart and welded on the main stirrup 200, each auxiliary stirrup 300 is U-shaped and fixedly welded with two points on the main stirrup 200, and the size specifications of the plurality of auxiliary stirrups 300 can be the same or different. Figure 2 As shown in the figure, the T-beam top plate single stirrup welding forming method includes the following steps:

[0057] Figure 3 As shown in the figure, the T-beam top plate single stirrup welding forming method includes the following steps:

[0058] S1, the welding moving frame 1 is located at the feeding position, and the main stirrup 200 and the plurality of auxiliary stirrups 300 are fed to the welding work station on the welding moving frame 1;

[0059] S2, the welding moving frame 1 moves from the feeding position to the discharging position, and at the same time, the main stirrup 200 and the plurality of auxiliary stirrups 300 located at the welding work station are synchronously welded and formed to obtain a single stirrup;

[0060] S3, the welding moving frame 1 moves to the discharging position, and the discharging of the single stirrup is performed at the discharging position;

[0061] S4, the welding moving frame 1 moves from the discharging position to the feeding position, and step S1 is executed.

[0062] ​The present invention provides a method for welding single stirrups on the top slab of a T-beam. This method utilizes a welding moving frame 1 for the load-bearing welding of the main stirrups 200 and multiple auxiliary stirrups 300, which improves the positioning accuracy of the main stirrups 200 and the auxiliary stirrups 300 and enhances the welding quality. The welding moving frame 1 reciprocates between a loading position and a unloading position. Figure 4 and Figure 6 As shown, when the welding moving frame 1 moves from the loading position to the unloading position, synchronous welding can be performed, that is, welding is completed during the movement. When the welding moving frame 1 is at the unloading position, welding is also completed, and single stirrups can be unloaded at the unloading position. When the welding moving frame 1 moves in the opposite direction from the unloading position to the loading position, the single stirrups undergo subsequent processes such as unloading and storage, realizing that the single stirrup storage process is synchronized with the movement of the welding moving frame 1. When the welding moving frame 1 is at the loading position, the main stirrup 200 and multiple auxiliary stirrups 300 are loaded again at the welding position. This process is repeated, realizing that welding or unloading can be performed simultaneously with the movement of the welding moving frame 1, which helps to save process time, avoids positional interference between loading and unloading, and improves the unloading and loading efficiency of single stirrups. There is no need for manual placement of loading materials, and the single stirrup forming efficiency is high and the finished product consistency is good.

[0063] In some embodiments, in step S1, the welding moving frame 1 is also provided with a pre-storage station, and multiple auxiliary stirrups 300 are fed from the pre-storage station to the welding station.

[0064] like Figure 6 As shown, welding stations and pre-storage stations are spaced apart along the Y direction on the welding moving frame 1. The welding stations can simultaneously fix the main stirrups 200 and multiple auxiliary stirrups 300 for synchronous welding and fixing of the multiple auxiliary stirrups 300. The pre-storage stations are used for temporary storage of the multiple auxiliary stirrups 300. The placement of the multiple auxiliary stirrups 300 in the pre-storage stations is the same as that in the welding stations, which facilitates the rapid loading of the multiple auxiliary stirrups 300 from the pre-storage stations to the welding stations.

[0065] In a preferred embodiment, multiple auxiliary stirrups 300 located at the pre-storage station are fed to the welding station in one go to improve feeding efficiency; simultaneously, multiple auxiliary stirrups 300 are fed to the pre-storage station to facilitate the next feeding. When both the pre-storage station and the welding station are full, the welding moving frame 1 begins to move and weld.

[0066] In some embodiments, in step S2, at the welding station, the welding device 3 is positioned adjustablely on the welding moving frame 1. In the non-welding state, the welding device 3 can avoid the feeding of the main stirrup 200 and the auxiliary stirrup 300, as well as the unloading of a single stirrup.

[0067] Specifically, the main stirrup 200 and the plurality of auxiliary stirrups 300 are fixed on the top surface of the welding mobile frame 1, before welding, the welding device 3 is retracted below the top surface of the welding mobile frame 1, which is beneficial to loading and unloading on the top surface; when welding, the welding device 3 extends from below to above the top surface and moves towards the welding joint of the main stirrup 200 and the auxiliary stirrup 300 to facilitate welding forming, after welding, the welding device 3 moves away from the welding joint, and then is lowered below the top surface again. Among them, the number of welding devices 3 is the same as the number of welding joints, and a plurality of welding joints are used to realize synchronous welding, thereby improving the welding efficiency and the consistency of finished products.

[0068] The application also provides a T-shaped beam top plate single-piece stirrup welding forming equipment for realizing the T-shaped beam top plate single-piece stirrup welding forming method.

[0069] As Figures 4-9 , the T-shaped beam top plate single-piece stirrup welding forming equipment comprises a welding mobile frame 1, a plurality of fixing assemblies 2 and welding devices 3, the welding mobile frame 1 is slidably arranged between a loading position and an unloading position; the plurality of fixing assemblies 2 are arranged on the top surface of the welding mobile frame 1, the top surface of the welding mobile frame 1 is provided with a welding station and a pre-storage station, the main stirrup 200 is fixed on the welding station by at least five fixing assemblies 2, at least one fixing assembly 2 is arranged at the end of the main stirrup 200, and the remaining four fixing assemblies 2 are arranged on both sides of the length direction of the main stirrup 200; each auxiliary stirrup 300 is fixed on the welding station and / or the pre-storage station by at least two fixing assemblies 2, and the two fixing assemblies 2 are arranged on two adjacent sides of the U-shaped auxiliary stirrup 300. The top surface of the welding mobile frame 1 is provided with a plurality of through holes 11, and a plurality of welding devices 3 are adjustably arranged on the welding mobile frame 1 and respectively arranged in the plurality of through holes 11, the welding device 3 can move towards the main stirrup 200 and the auxiliary stirrup 300 to form a single-piece stirrup by welding, and the welding device 3 can move away from the single-piece stirrup to avoid unloading of the single-piece stirrup.

[0070] As Figure 4 shown in the drawings, three auxiliary stirrups 300 need to be fixed by interval welding on each main stirrup 200, and the pre-storage station and the welding station are respectively provided with three auxiliary stirrups 300, six through holes 11 are arranged corresponding to six welding joints on the welding station, and six welding devices 3 are arranged in one-to-one correspondence with the six through holes 11 to perform welding, so that a plurality of auxiliary stirrups 300 are simultaneously fixed by welding, thereby improving the welding efficiency. It should be noted that, in order to facilitate the loading and positioning of the main stirrup 200 and the auxiliary stirrup 300, the top surface of the welding mobile frame 1 is also provided with an avoiding hole 12, so that the handling manipulator 9 can place and position the main stirrup 200 or the auxiliary stirrup 300 on the fixing assembly 2, and the fixing positions of each main stirrup 200 and each auxiliary stirrup 300 are respectively provided with two avoiding holes 12.

[0071] In some embodiments, the fixing component 2 includes two spring pieces 21, which are fixed to the top surface of the welding moving frame 1. The two spring pieces 21 are parallel to each other and spaced apart to form an elastic clamping space, in which the main hoop 200 or the auxiliary hoop 300 can be clamped.

[0072] like Figure 5 As shown, the two spring pieces 21 have identical structures and are arranged opposite each other. The gap between the two spring pieces 21 forms an elastic clamping space. When the main hoop 200 or the auxiliary hoop 300 is fed, the handling robot 9 will press the main hoop 200 or the auxiliary hoop 300 into the space between the two spring pieces 21, so that the main hoop 200 and the auxiliary hoop 300 are clamped between the two spring pieces 21. When pressing in the main hoop 200 and the auxiliary hoop 300, the handling robot 9 will use the clearance hole 12 to achieve the pressing in place, so that the main hoop 200 and the auxiliary hoop 300 can be supported on the top surface of the welding moving frame 1. The two spring pieces 21 form line contact with the main hoop 200 or the auxiliary hoop 300, improving the clamping stability.

[0073] In some embodiments, the two spring pieces 21 of the fixing component 2 are arranged perpendicular to the top surface of the welding moving frame 1, the bottom ends of the two spring pieces 21 are adjustablely fixed to the top surface of the welding moving frame 1, and the top ends of the two spring pieces 21 are bent away from each other to form a guide portion 23.

The base plate is used to connect to the top surface of the welding moving frame 1, and the upright plate forms the side wall of at least part of the elastic clamping space. Two L-shaped thin plates are arranged back to back. The base plate is provided with an elongated hole 22, which corresponds to the position of the round hole 13 (generally a threaded hole) on the top surface of the welding moving frame 1. Connectors (such as bolts) can pass through the elongated hole 22 and the round hole 13 and lock and fix the position of the spring piece 21 (the bolt nut can press the base plate tightly against the top surface), so that the position between the two spring pieces 21 can be adjusted and fixed. It can be understood that the long axis of the elongated hole 22 is perpendicular to the elastic upright plate. In the two spring pieces 21, the top of the upright plate of at least one spring piece 21 is bent at a certain angle away from the other spring piece 21 to form a guide part 23, which facilitates the pressing in of the main stirrup 200 or the auxiliary stirrup 300. Preferably, the top plates of the upright plates of the two spring plates 21 are bent at the same angle to form an open guide portion 23. Since the distance between the two spring plates 21 (i.e. the width of the elastic clamping space) is not greater than the outer diameter of the main stirrup 200 or the auxiliary stirrup 300, the guide portion 23 is provided to facilitate the smooth guidance and pressing of the main stirrup 200 and the auxiliary stirrup 300 into place.

As shown in Figure 7 , the bottom of the welding moving frame 1 is fixedly provided with a sliding block 42 which is slidingly arranged on the first guide rail 41, and the two first guide rails 41 are arranged back-to-back in an L shape to limit the sliding direction of the sliding block 42 along the X direction.
