[0001] The utility model application relates to the technical field of traction inverters, and in particular to a convenient disassembly and assembly traction inverter. Background Art

[0002] The traction inverter is one of the key components of the train. It is installed at the bottom of the train car. Its main function is to convert electrical energy between DC and AC systems, converting the 1500V DC power from the contact network into three-phase AC power, and realizing the starting, braking and speed control of the AC traction motor through voltage and frequency regulation. It mainly includes high-power diodes, thyristors, capacitors and reactors.

[0003] When the traction inverter is installed on the bottom of the train, it is mostly fixed by multiple evenly distributed bolts. However, due to the excessive number of bolts, it is laborious and tedious to disassemble it one by one. Multiple disassembly can easily cause the threaded holes to wear or even slip. Utility Model Content

[0004] In order to solve the problem that the existing traction inverter is complicated and laborious to operate during assembly and disassembly, the utility model provides a convenient detachable traction inverter to solve the above problem.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The camshaft is fixed to the chassis and is secured to the chassis by a spring that is secured to the chassis' bottom surface and is adapted to engage said chassis' bottom surface and engage said chassis' bottom surface.

[0007] Furthermore, a fixing hole is provided inside one end of each of the fixed angle plates extending to the outside of the mounting base plate, and a sliding groove cooperating with a limit block is provided at the bottom of the traction inverter body.

[0008] Furthermore, the feed trough extends to the middle portion above the limiting groove, the thickness of the feed trough is equal to the thickness of the mounting base plate, and the width of the feed trough is greater than the width of the limiting plate.

[0009] Furthermore, the thickness of the limiting groove is smaller than the thickness of the mounting base plate, the limiting groove is arranged to be connected to the feed chute on the front side, and the outer edge is arranged to be an arc with the supporting rotating rod as the center.

[0010] Furthermore, the limit block is configured as a rectangle that matches the feed trough, the thickness of the limit block extending to the outside of the traction inverter body is less than the thickness of the feed trough, and each of the fixed slide bars is configured as a "T" shape.

[0011] Furthermore, the limit block extends to the middle of the outer end of the traction inverter body and is provided with a fixing screw hole, and the inner thread of the fixing screw hole is threadedly sleeved with a limit bolt, and the top of the limit bolt is slidably fitted with the bottom surface of the traction inverter body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] In the utility model, after the mounting base is fixed to the bottom of the train through the split fixing structure, it is only necessary to screw a limit bolt to release the limit of the limit block by the limit bolt, and then press the limit block and rotate the traction inverter body to complete the disassembly. The disassembly process is simpler and more labor-saving, which solves the problem of the existing traction inverter being more cumbersome and labor-intensive during disassembly and assembly, and greatly improves the convenience of the traction inverter during disassembly and assembly.

[0019] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] Reference Figure 1 、 Figure 2 and Figure 3 , a convenient disassembly and assembly traction inverter, including a traction inverter main body 1, a mounting base 2 is provided at the bottom of the traction inverter main body 1, and fixed angle plates 3 are fixed at the corners of the mounting base 2, and a fixing hole is provided inside each of the fixed angle plates 3 extending to the outside of the mounting base 2, and a supporting rotating rod 5 is fixed at the center position of the bottom surface of the traction inverter main body 1, and a feed trough 4 cooperating with the supporting rotating rod 5 is provided inside the mounting base 2, and the feed trough 4 extends to the middle part above the limiting groove 7, the thickness of the feed trough 4 is equal to the thickness of the mounting base 2, and the width of the feed trough 4 is greater than the width of the limiting plate 6, the thickness of the limiting groove 7 is less than the thickness of the mounting base 2, the limiting groove 7 is set to pass through the feed trough 4 on the front side, and is set to an outer edge with the supporting rotating rod 5 as the center of the circle. A limit plate 6 is symmetrically fixed to the lower part of the supporting rotating rod 5, and a limit groove 7 cooperating with the limit plate 6 is provided in the middle of the bottom surface of the mounting base plate 2. A limit block 8 is slidingly provided inside the end of the feed trough 4 away from the limit groove 7. A slide groove cooperating with the limit block 8 is provided at the bottom of the traction inverter main body 1, and the limit block 8 slides and extends into the interior of the traction inverter main body 1. A movable card plate 9 is fixed to one end of the limit block 8 extending into the interior of the traction inverter main body 1, and fixed slide rods 10 are slidably sleeved at the four corners of the movable card plate 9. The bottom of each fixed slide rod 10 is fixed to the bottom surface of the interior of the traction inverter main body 1, and a spring 11 is slidably sleeved on the fixed slide rod 10 at the top of each movable card plate 9, and both ends of the spring 11 are respectively fixed on the fixed slide rod 10 and the movable card plate 9.

[0021] Specifically, when the traction inverter body 1 needs to be installed, first fix the fixed angle plate 3 to the bottom of the train with bolts, then press the limit block 8, so that the limit block 8 drives the movable card plate 9 to compress the spring 11 to move toward the inside of the traction inverter body 1, until the bottom surface of the limit block 8 is flush with the bottom surface of the traction inverter body 1, and then align the supporting rotating rod 5 and the limit plate 6 with the feed trough 4 and push them into the limit groove 7, so that the edge of the limit plate 6 abuts against the edge of the limit groove 7, and then rotate the limit plate 6 so that the limit plate 6 rotates to be misaligned with the limit slot 7. At this time, the traction inverter main body 1 rotates to be aligned with the mounting base 2. At the same time, the support rotating rod 5 is limited by the limit plate 6. At this time, the limit block 8 moves to be aligned with the feed trough 4. The limit block 8 is subjected to the extrusion force and can be moved to the inside of the feed trough 4 under the push of the spring 11. In this way, the traction inverter main body 1 is limited by the limit block 8 to prevent the traction inverter main body 1 and the mounting base 2 from rotating relative to each other, and the traction inverter main body 1 can be fixed to the mounting base 2.

[0022] As an optimization solution, Figure 3 As shown, the limit block 8 is set to be a rectangle that matches the feed trough 4. The thickness of the limit block 8 extending to the outside of the traction inverter main body 1 is less than the thickness of the feed trough 4. The limit block 8 extends to the middle of the outer end of the traction inverter main body 1 and is provided with a fixing screw hole 12, and the internal thread of the fixing screw hole 12 is threadedly sleeved with a limiting bolt 13. The top of the limiting bolt 13 slides in contact with the bottom surface of the traction inverter main body 1, and each of the fixed slide rods 10 is set to a "T" shape.

[0023] Specifically, after the limit block 8 moves to the inside of the feed trough 4 under the push of the spring 11, the limit bolt 13 is screwed into the fixing screw hole 12 and fixed. The limit block 8 can be limited by the limit bolt 13 to prevent the limit block 8 from being pressed into the inside of the traction inverter body 1 in an unplanned situation, so that the connection between the traction inverter body 1 and the mounting base 2 is more firmly established.
