Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a high-strength welding joint structure. Background Art

[0002] The welding method is fixed, and the length of a single rail is generally around 25 meters or even longer. Therefore, considering the cost and feasibility, the two rails are generally welded by thermite welding to form a seamless line. However, since the welding joints of thermite welding are relatively weak, the welding joints between the rails are very easy to break during heavy-load operation.

[0003] After searching, the publication number CN219772566U discloses a reinforced insulation rail welding joint, including a rail. The utility model adopts a high-temperature molded integral coating process to form a steel part and an insulating material into a whole during actual use, so that there is no gap between the two, and conductive substances are prevented from entering, thereby improving insulation reliability, achieving maintenance-free, and reducing the maintenance workload of line workers. At the same time, the reinforcement splint is connected to the rail through a mortise and tenon, a sliding groove, a tenon, and a rail, and finally the nut is tightened to arrange the appearance and debug. Among them, the technical conditions of the bolt, the large hexagonal nut, and the washer meet the requirements of GB / T1231. At the same time, the fixing bolt fixes the rail and the reinforcement splint through the first pin hole, the second pin hole, and the fixing nut. By filling the epoxy adhesive between the rail and the reinforcement splint, the rail and the reinforcement splint can be more closely contacted, thereby increasing insulation.

[0004] Based on the above patent, in actual use, the reinforcement plywood is connected to the rail through the mortise and tenon, the sliding groove and the tenon, and finally the nut is tightened to tidy up the appearance and debug. Among them, the technical conditions of the bolts, large hexagonal nuts and washers meet the requirements of GB / T1231. At the same time, the fixing bolts fix the rail and the reinforcement plywood through the first pin hole, the second pin hole and the fixing nut. By filling the epoxy adhesive between the rail and the reinforcement plywood, the contact between the rail and the reinforcement plywood can be made closer, and the insulation is increased. However, the tenon needs to be welded on the side of the rail, and then reinforced and fixed with the mortise and tenon, resulting in low reinforcement strength affecting subsequent use. In this regard, in response to this technical problem, the present application proposes a high-strength welded joint structure. Utility Model Content
