The supporting roller 1 and the rotating shaft 2 have an assembly relationship of direct connection or indirect connection, wherein the connection relationship can have three conditions: 1) the riding wheel 1 can be directly sleeved on the rotating shaft 2 in a rotating way, or the riding wheel 1 can be indirectly sleeved on the rotating shaft 2 in a rotating way (not shown in the figure), namely, the riding wheel 1 can rotate relative to the rotating shaft 2; 2) the riding wheel 1 is tightly sleeved on the rotating shaft 2 (not shown in the figure), and the riding wheel 1 and the rotating shaft 2 rotate together at the moment; 3) the supporting roller 1 and the rotating shaft 2 are manufactured as an integral structure (not shown in the figure), and the supporting roller 1 and the rotating shaft 2 rotate together. No matter the connection relationship between the idler 1 and the rotating shaft 2 is in the above three cases, the idler 1 can rotate around the axis thereof, and the rotating shaft 2 can be a rotating member or a fixed member (which can be set according to actual needs). It should be noted that the riding wheel 1 of the present invention can be a single piece (not shown) or an assembly, and fig. 1 and 4 show the riding wheel 1 in the case of an assembly: namely, the riding wheel 1 consists of a riding wheel body 1a, a riding wheel shaft core 1b and a riding wheel sealing cover 1 c. It is the idler 1 that can perform the rotary motion, so the utility model can realize that the welding equipment can perform the welding on the welding seams 3 with various lengths and can ensure the welding quality: referring to fig. 3, the target plate weldment 4 is placed on the welding bench and moves along with the conveying device (the target plate weldment 4 can also move by the rotation of the riding wheel 1), and meanwhile, the welding gun 5 is arranged on one side of the target plate weldment 4 to be spliced and welds the target plate weldment 4, while the riding wheel 1 of the utility model is arranged on the other side of the target plate weldment 4 (the side is opposite to the partition board of the welding gun 5) and supports the target plate weldment 4, and at this time, the target plate weldment 4 moves and moves by the driving of the conveying device or/and the rotating wheel 1, so that the weld 3 obtained by welding the target plate weldment 4 also extends, and due to the rotatability of the riding wheel 1, the riding wheel 1 and the target plate weldment 4 can always keep good contact in the welding process, in other words, the riding wheel 1 can perform and complete the holding of the target plate weldment 4 when welding the weld 3 with different lengths are welded in the welding process And the riding wheel 1 and the target plate weldment 4 are not easy to slide excessively to cause mutual damage, so that the welding quality of the welding seam 3 can be ensured.
In order to obtain better welding quality of the welding seam 3, a cooling channel 6 through which a cooling medium can pass can be arranged inside the riding wheel 1 or/and inside the rotating shaft 2, and the situation shown in fig. 4 is the situation that the cooling channel 6 is arranged inside the riding wheel 1. It is clear that by providing the cooling channels 6, the heat generated by the welding can be removed by means of various cooling media, which in turn provides an effective cooling of the weld seam 3 and thus promotes an improved welding quality. Here, the cooling medium may be water, air or even oil or other cooling liquid, wherein water is preferred as the cooling medium because water has the advantages of carrying more heat and being more economical and widely available, and the operation and maintenance thereof are relatively simple. Furthermore, in order to facilitate the manufacture and the later maintenance, the utility model can also be provided with at least one distribution hub 7 beside the shaft of the riding wheel 1, wherein the side of the shaft is arranged along the axial direction of the riding wheel 1 and is distributed adjacent to the riding wheel 1, and the distribution hub 7 is provided with a special switching channel 8 to be communicated with the cooling channel 6 on the riding wheel 1 (see fig. 1 and 4).

It should also be noted that when the cooling channel 6 comprises a flow channel structure (not shown) for guiding the cooling medium to form a circular flow inside the idler 1, the cooling medium will have a better cooling effect on the idler 1 and thus on the weld 3.
In the present invention, the distribution hub 7 and the rotating shaft 2 may be a rotatable member or a stationary member. In particular, it is preferred that both the distribution hub 7 and the shaft 2 are stationary (as is the case with the embodiment shown in fig. 1 to 4), at which time the distribution hub 7 and the shaft 2 can be arranged very conveniently and can be well adapted to the operation of the welding apparatus. Whether the distribution hub 7 and the rotating shaft 2 are rotatable rotating parts or non-rotatable fixed parts, the arrangement of the shaft seal 9 between the riding wheel 1 and the distribution hub 7 or/and between the riding wheel 1 and the rotating shaft 2 can bring about the positive effect of preventing the cooling medium from leaking, which is advantageous for improving the operational reliability of the welding equipment device, as shown in fig. 1 and 4. In particular, the distribution hubs 7 according to the utility model are provided in total with two distribution hubs, one distribution hub 7 being responsible for supplying the idler 1 with cooling medium and the other distribution hub 7 being responsible for receiving the cooling medium from the idler 1, as is the case with the embodiments shown in fig. 1 to 4, which is advantageous for the layout of the cooling system of the welding apparatus and for the later maintenance.
