[0032] Two secondary beams 2 are welded on both ends of the bogie frame; the supporting structure can adjust the length of the device according to the distance between the secondary beams 2, thereby achieving stable support of the secondary beams 2 by the device and precise welding between the secondary beams 2 and the bogie frame; at the same time, the supporting structure can be extended and retracted, which can effectively avoid the inward contraction of both sides of the secondary beams 2 after welding, making it difficult to remove the device; at the same time, it solves the problem of damage to the product and wear of the device during disassembly.

[0033] The reinforcing structure strengthens the device, effectively increasing the structural stability of the device and enabling it to withstand a larger load; the first connecting structure and the second connecting structure are respectively pressed against the second tie beam 2 on both sides of the bogie frame, effectively preventing the second tie beam 2 from shaking during welding and affecting the welding accuracy.

[0034] The supporting structure includes a jack 3, and the two ends of the jack 3 are connected to the supporting beam 1 and the reinforcing structure respectively. Since the size and weight of the secondary beam 2 are large, a large supporting force is required during welding; the jack 3 has a strong load-bearing capacity and can provide stable support for the secondary beam 2 to prevent the position of the secondary beam 2 from shifting during welding, which affects the welding accuracy between the secondary beam 2 and the steering frame. At the same time, the jack 3 is easy to operate and can quickly and efficiently adjust the support position of the device and the secondary beam 2, thereby improving production efficiency.

[0035] The jack 3 includes a cylinder 31; a mounting base plate 33 is provided at one end of the cylinder 31, and a piston rod 32 is provided at the other end of the cylinder 31; a connecting plate 11 is provided at the end of the support beam 1; the mounting base plate 33 is connected to the connecting plate 11; the end of the piston rod 32 is connected to a mounting plate 34, and the mounting plate 34 is connected to the reinforcement structure.

[0036] A control rod is provided on the side of the cylinder 31; by pulling the control rod, the extension length of the piston rod 32 can be controlled; thereby pushing or pulling back the reinforcing structure and the second connecting structure connected to the mounting plate 34; and realizing rapid installation and disassembly of the device; the connecting plate 11 is connected to the mounting base plate 33, so that the support beam 1 can provide support for the jack 3.

[0037] A first mounting hole is provided on the side of the mounting base plate 33, and a second mounting hole is connected to the side of the connecting plate 11; a mounting bolt 12 is connected to the first mounting hole, and an end of the mounting bolt 12 extends out of the second mounting hole.

[0038] The mounting bolts 12 pass through the first mounting holes provided on the side of the mounting base plate 33 and the second mounting holes provided on the side of the connecting plate 11, and press the mounting base plate 33 against the connecting plate 11. The mounting base plate 33 and the connecting plate 11 are connected by bolts, and the connection structure is simple, the connection is stable and reliable, and it is easy to install and disassemble. There are four first mounting holes and four second mounting holes, which are respectively provided at the four corners of the mounting base plate 33 and the connecting plate 11.

[0039] The reinforcement structure includes a reinforcement rib 4 , one end of the reinforcement rib 4 is connected to the mounting plate 34 , and the other end of the reinforcement rib 4 is connected to the second connection structure.

[0040] The reinforcement structure is provided with four reinforcement ribs 4, which are arranged crosswise; the reinforcement ribs 4 enhance the rigidity of the bottom surface of the mounting plate 34 and the second connection structure, and enhance the stability of the connection between the mounting plate 34 and the second connection structure.

[0041] The first connection structure includes a first connection block 5 , and the second connection structure includes a second connection block 51 ; the side surface of the first connection block 5 is connected to the end of the support beam 1 ; the side surface of the second connection block 51 is connected to the end of the reinforcing rib 4 .

[0042] The first connecting block 5 and the second connecting block 51 are respectively pressed against the second tie beams 2 on both sides of the bogie frame, so as to effectively prevent the second tie beams 2 from shaking during welding and affecting the welding accuracy.

[0043] The first connection block 5 and the second connection block 51 are both provided with a buffer protection structure on their sides. The buffer protection structure can buffer the connection block and the product surface, preventing the jack 3 from damaging the surface of the second tie beam 2 due to excessive support force, which affects the product specification accuracy and causes manpower and material losses; at the same time, it can prevent the surface of the connection block from being worn due to multiple installations of the device, resulting in an uneven surface and inaccurate support position of the second tie beam 2.

[0044] The buffer protection structure includes a rubber layer, which is bonded to the side of the first connection block 5 and the second connection block 51. The rubber layer has good elasticity and can effectively buffer the surface of the connection block and the second tie beam 2; the friction coefficient of the rubber layer is large, so that the connection between the device and the second tie beam 2 is more stable. The rubber layer has good toughness, low manufacturing cost, and long service life, and is more suitable for the device.

[0045] The support beam 1 is a square tube; a handle 13 is connected to the side of the support beam 1. The support beam 1 is a square tube, which is convenient for workers to install and disassemble; and the hollow tubular structure is light in weight, stable in structure, and strong in strength, and can withstand a large load; workers can quickly and efficiently operate the device by holding the handle 13, effectively preventing the device from slipping out of their hands and causing safety accidents.

Both adopt a square structure, so that the contact area at the connection is larger, which can make the connection more stable.

[0048] The specific working process of the utility model is as follows:

[0049] First, adjust the jack 3 according to the spacing between the two tie beams 2 on both sides to pre-adjust the length of the device. Then use the crane hook to install the device in the middle of the two tie beams 2 on both sides. When the welding is completed and the weld is cooled, remove the force of the jack 3 and take out the device for next use.

[0050] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
