Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Please refer to fig. 1-3, the utility model relates to a passenger train is with fuel tank bracket structure includes U type connecting plate 1, second connecting plate 2, quarter bend 3, strengthening rib 4, weld nut 5, bolt 6, plain washer 7 and spring washer 8, U type connecting plate installs on the automobile body chassis, U type connecting plate 1 passes through welded fastening with the automobile body chassis, second connecting plate 2 is installed at quarter bend 3 both ends, second connecting plate 2 passes through welded fastening with quarter bend 3, strengthening rib 4 is installed in quarter bend 3 below, 4 one end of strengthening rib are connected with second connecting plate 2, the 4 other ends of strengthening rib are connected with quarter bend 3, weld nut 5 fixed mounting is on U type connecting plate 1, weld nut 5 cooperates with bolt 6, plain washer 7 and spring washer 8 are installed between weld nut 5 and bolt 6.
The utility model relates to a passenger train is with fuel tank bracket structure's theory of operation as follows:
the fuel tank bracket and a vehicle body underframe adopt a four-point supporting structure, the welding position of the fuel tank bracket and a vehicle frame is welded by adopting a U-shaped connecting plate 1, and a corresponding steel plate is welded horizontally above a rectangular tube 3 of the vehicle body underframe at the welding part, so that the welding seam length of the U-shaped connecting plate 1 is further increased, the supporting strength is improved, one side of the fuel tank bracket adopts a mode of welding the rectangular tube 3 and a second connecting plate 2, and the U-shaped connecting plate 1 and the second connecting plate 2 are fixed by adopting two-point bolt nuts, so that the strength requirement is fully met;
secondly, the oil tank and the oil tank bracket are connected by adopting a pull belt type single-head welding stud tightening belt, before the oil tank is installed, a circle of formed round shock-proof pad is added at the tightening belt pressing position of the oil tank, so that the mutual extrusion action and friction between the oil tank and the tightening belt and between the oil tank and the oil tank bracket caused by vehicle body shaking are effectively weakened;
thirdly, a gasket is added between each fixing point of the U-shaped connecting plate 1 and each fixing point of the second connecting plate 2, and then the bracket assembly is welded on the bottom frame according to the relevant positioning size in the welding process, so that the welding accuracy of the positioning size of the four supporting points of the oil tank bracket is effectively guaranteed; when the assembly procedure of the assembly oil tank is reached, the bracket assembly is disassembled, the oil tank is fixed on the bracket after the gasket is taken down (not assembled), and then the oil tank is supported and tightened from the bottom of the frame, so that the assembly is completed. The removal of the gasket ensures the installation space required by the disassembly and reassembly of the bracket in the general assembly process. By the method, welding errors of the bracket in the advancing direction of the vehicle are eliminated, positioning accuracy of a supporting point of the bracket is guaranteed, and convenience in installation is improved.
