Technical Field

[0001] This utility model belongs to the field of mixed-rail vehicle technology, specifically relating to a vibration damping and protection plate for the frequency converter in the electrical room of a mixed-rail vehicle cover device. Background Technology

[0002] A cover device for molten iron mixing cars is used to cover the molten iron during transportation, which can significantly reduce heat loss during transportation and waiting, and effectively reduce the emission of pollutants such as smoke and dust into the atmosphere. For example, CN202310035770.9 discloses a mechanical intelligent cover-applying DC-DC electronic control system and control method for molten iron mixing cars. Figure 4 As shown, the mixed-rail car 10 is equipped with an electrical control system for controlling the cover device 1. The electrical control components include a frequency converter 3, a battery pack 4, and a power supply box 5. These components are installed in the electrical room 2 at the end of the mixed-rail car 10. For example, the frequency converter 3 is directly bolted to the crossarm 9 inside the electrical room 2. During the operation of the mixed-rail car, electrical components such as the frequency converter 3 are often affected by vibration, impact, and dust, leading to performance degradation and increased failure rate. Therefore, it is necessary to design a vibration damping and protection plate for the frequency converter to solve the above problems. Utility Model Content

[0003] This utility model provides a vibration damping and protection plate for the frequency converter in the electrical room of a mixed-rail vehicle cover device. The frequency converter can be installed in the electrical room through this vibration damping and protection plate, which can effectively absorb the vibration and external impact generated during the operation of the mixed-rail vehicle, reduce dust accumulation on the surface of the frequency converter, and significantly reduce the failure rate of the frequency converter.

[0004] The technical solution of this utility model to solve the technical problem is as follows:

[0005] This utility model provides a vibration damping and protective plate for the frequency converter in the electrical room of a mixed-rail vehicle cover device, including a vertically arranged protective plate. The top of the protective plate is provided with a front top plate. The plate body is evenly provided with multiple frequency converter mounting holes and protective plate connection holes. The protective plate connection holes are provided with vibration damping connecting bolts. The vibration damping connecting bolts include a double-ended screw with external threads at both ends in the axial direction, a buffer pad covering the middle section of the double-ended screw, and a fastening nut screwed onto the external threads.

[0006] As a further improvement to the technical solution, the protective plate and the front top plate are integrally formed structures with an "L" shaped cross section, and downward sloping eaves are provided on the front side and the left and right sides of the front top plate.

[0007] As a further improvement to the technical solution, the protective plate, the front top plate, and the sloping eaves plate are all made of galvanized steel plate.

[0008] As a further improvement to the technical solution, the sloping eaves plate forms an angle of 90°-135° with the front top plate.

[0009] As a further improvement to the technical solution, both the double-ended screw and the fastening nut are galvanized parts.

[0010] As a further improvement to the technical solution, the buffer pad is a rubber component.

[0011] As a further improvement to the technical solution, the protective plate has at least four connection holes, which are symmetrically opened at the four corners of the protective plate.

[0012] Compared with the prior art, the vibration damping and protection plate for the frequency converter in the electrical room of the mixed iron car cover device described in this utility model has a simple structure and is very convenient to manufacture and use. Through the integrated structure of the "L"-shaped protection plate and the front top plate and the vibration damping connecting bolts, it not only improves the protection capability of the frequency converter, but also reduces the failure rate of the frequency converter through vibration damping treatment, thereby improving the reliability and stability of the equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art to which this disclosure pertains. The terms "upper," "lower," "left," "right," "front," and "rear" used in the present patent application specification and claims are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship also changes accordingly. Any aspects not detailed in the present utility model are well-known technologies to those skilled in the art.

[0020] like Figure 4 and Figure 5 As shown, the existing mixed-rail car 10 is equipped with a cover device 1. The cover device is controlled by an electronic control system. The electronic control components are installed in the electrical room 2, which generally include a frequency converter 3, a battery pack 4, and a power supply box 5. The frequency converter 3 is directly installed on the crossarm 9 inside the electrical room 2 by bolts.

[0021] To reduce the impact of vibration on the frequency converter 3 in the electrical room 2 during the operation of the mixed-rail car 10, such as... Figure 1-3 As shown, this utility model provides a vibration damping and protective plate for the frequency converter in the electrical room of a mixed-rail vehicle cover device. It includes a vertically arranged protective plate 6, which is rectangular in shape. A front top plate 11 is integrally formed on its top, and together they form an L-shaped overall structure, facilitating installation and improving stability. Downward-sloping eaves 12 are respectively provided on the front and left / right sides of the front top plate 11, forming a hat shape. The angle between the eaves 12 and the front top plate 11 is 90°-135°, preferably 120°, to enhance dust protection and structural strength. The protective plate 6, the front top plate 11, and the eaves 12 are all made of galvanized steel sheet to improve corrosion resistance and service life.

[0022] The protective plate 6 has multiple inverter mounting holes 8 evenly spaced on its body for installing inverters. In addition, at least four protective plate connection holes 13 are symmetrically located at the four corners of the protective plate 6. Each protective plate connection hole 13 is equipped with a shock-absorbing connecting bolt 7 for connecting to the crossarm 9 inside the electrical room 2.

[0023] The vibration-damping connecting bolt 7 includes a double-ended screw 71 with external threads 72 at both axial ends, a buffer pad 73 covering the middle section of the double-ended screw 71, and a fastening nut 74 screwed onto the external threads 72. Both the double-ended screw 71 and the fastening nut 74 are galvanized to increase the service life of the components. The buffer pad 73 is a rubber component used to absorb vibration.

[0024] During installation, connection holes corresponding to the connection holes 13 of each protective plate are made on the crossarm 9. After aligning the connection holes 13 of each protective plate 6 with the connection holes on the crossarm 9, double-ended screws 71 are inserted, so that the buffer pads 73 are between the protective plate 6 and the crossarm 9. Then, fastening nuts 74 are screwed into both ends of the double-ended screws 71 for fixation. Finally, the frequency converter 3 is installed on the protective plate 6 through the frequency converter mounting holes 8 and bolts. When the mixing car 10 is in operation, the elastic deformation of the buffer pads 73 can effectively isolate the vibration generated during the operation of the mixing car, preventing the vibration from being directly transmitted to the frequency converter, thereby extending the service life of the frequency converter. Through the action of the front top plate 11 and the inclined eaves plate 12, external dust or debris can be blocked, further protecting the frequency converter 3.
