Description

Technical Field

[0001] This utility model belongs to the field of mining equipment installation technology, specifically a mining frequency converter impact-resistant mounting base. Background Technology

[0002] Mining frequency converters are power electronic devices specifically designed for mining scenarios such as coal mines and metal mines. Their core function is to precisely regulate the speed of mining motors by changing the frequency and voltage of the input power supply, thereby meeting the needs of efficient, energy-saving, and safe operation of mining equipment.

[0003] In mining operations, impact-resistant mounting bases are frequently used to install frequency converters. While existing impact-resistant mounting bases can provide basic impact resistance, they lack adequate protection for the frequency converters. Due to the extremely complex and harsh working environment in mining areas, with widespread vibration sources, minerals frequently fall from heights. If a mineral accidentally hits the frequency converter mounted on the impact-resistant mounting base, the converter is highly likely to be damaged by the impact, thus affecting the normal operation of the entire mining operation. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to address the above problems. This utility model provides an impact-resistant mounting base for mining frequency converters, which has the advantage of protecting the frequency converters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant mounting base for a mining frequency converter, comprising a base plate, a damping spring shock absorber fixedly connected to the top of the base plate, a mounting base fixedly connected to the top of the damping spring shock absorber, a frequency converter movably connected to the top of the mounting base, a drive motor fixedly connected to the top of the base plate, a rotating shaft fixedly sleeved at the other end of the output shaft of the drive motor, a rectangular plate fixedly sleeved on the outer surface of the rotating shaft, rotating rods hinged to the left and right sides of the top of the rectangular plate, and a protective plate hinged to the other end of the rotating rod. There are two protective plates, and the bottoms of both protective plates are movably connected to the top of the mounting base.

[0006] As a preferred embodiment of this utility model, the top of the mounting base is provided with a sliding groove, and a limiting block is movably connected inside the sliding groove. The top of the limiting block is fixedly connected to the bottom of the protective plate.

[0007] As a preferred embodiment of this utility model, the number of damping spring shock absorbers is four, the four damping spring shock absorbers are of the same size, and the four damping spring shock absorbers are symmetrical about the center of the base plate.

[0008] As a preferred embodiment of this utility model, a mounting block is fixedly connected to the outside of the frequency converter, and a cylindrical block is fixedly connected to the top of the mounting base. The outer surface of the cylindrical block is movably connected to the inner surface of the mounting block.

[0009] As a preferred embodiment of this utility model, the top of the mounting base is fixedly connected to an L-shaped plate on the outside of the frequency converter, and the L-shaped plate is internally threaded with a threaded rod.

[0010] As a preferred technical solution of this utility model, a lifting plate is movably sleeved at the bottom of the threaded rod, and connecting rods are hinged to the left and right sides of the bottom of the lifting plate. A movable plate is hinged to the other end of the connecting rod. The bottom of the movable plate is movably connected to the top of the mounting base. A pin is fixedly connected to the outside of the movable plate.

[0011] As a preferred technical solution of this utility model, the top of the mounting base is provided with a limiting groove located directly below the moving plate, and a connecting block is movably connected to the inner surface of the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1.

[0014] 2. This utility model, by setting threaded rods, lifting plates, connecting rods, moving plates, and pins, rotates two threaded rods to move downwards, which in turn drives two lifting plates to move downwards.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides an impact-resistant mounting base for a mining frequency converter, including a base plate 1. A damping spring shock absorber 2 is fixedly connected to the top of the base plate 1. A mounting base 3 is fixedly connected to the top of the damping spring shock absorber 2. A frequency converter 11 is movably connected to the top of the mounting base 3. A drive motor 4 is fixedly connected to the top of the base plate 1. A rotating shaft 5 is fixedly sleeved at the other end of the output shaft of the drive motor 4. A rectangular plate 6 is fixedly sleeved on the outer surface of the rotating shaft 5. Rotating rods 7 are hinged to the left and right sides of the top of the rectangular plate 6. A protective plate 8 is hinged to the other end of the rotating rod 7. There are two protective plates 8, and the bottom of both protective plates 8 is movably connected to the top of the mounting base 3.

[0023] When the drive motor 4 is running, the rotating shaft 5 will drive the rectangular plate 6 to rotate, which in turn will cause the two rotating rods 7 to rotate and drive the two protective plates 8 to move towards each other. When the two protective plates 8 are in contact with each other, the purpose of protecting the frequency converter 11 is achieved, and the situation of minerals falling and damaging the frequency converter 11 due to vibration in the mining area is avoided.

[0024] The mounting base 3 has a groove 9 on its top, and a limit block 10 is movably connected inside the groove 9. The top of the limit block 10 is fixedly connected to the bottom of the protective plate 8.

[0025] The design of the slide groove 9 and the limiting block 10 serves to limit the movement of the protective plate 8, ensuring the stability of the horizontal movement of the protective plate 8.

[0026] The number of damping spring shock absorbers 2 is four. The four damping spring shock absorbers 2 are the same size and are symmetrical about the center of the base plate 1.

[0027] The design of four damping spring shock absorbers 2 provides better shock resistance to the frequency converter 11, avoids damage to the frequency converter 11 due to vibration, and improves the service life of the frequency converter 11.

[0028] Among them, the inverter 11 is fixedly connected to the outside of the mounting block 12, and the top of the mounting base 3 is fixedly connected to the cylindrical block 13. The outer surface of the cylindrical block 13 is movably connected to the inner surface of the mounting block 12.

[0029] The design of mounting block 12 and cylindrical block 13 serves the purpose of quickly installing frequency converter 11.

[0030] The top of the mounting base 3 is fixedly connected to an L-shaped plate 14 on the outside of the inverter 11, and the L-shaped plate 14 is internally threaded with a threaded rod 15.

[0031] The design of the L-shaped plate 14 serves to support the threaded rod 15.

[0032] The bottom of the threaded rod 15 is movably sleeved with a lifting plate 16. The left and right sides of the bottom of the lifting plate 16 are hinged with connecting rods 17. The other end of the connecting rod 17 is hinged with a movable plate 18. The bottom of the movable plate 18 is movably connected to the top of the mounting base 3. The outer side of the movable plate 18 is fixedly connected with a pin 19. The outer side of the pin 19 passes through the mounting block 12 and the cylindrical block 13 in sequence and extends into the interior of the cylindrical block 13.

[0033] The downward movement of the rotating threaded rod 15 will cause the lifting plate 16 to move downward, which in turn causes the two connecting rods 17 to rotate and drive the two moving plates 18 to move in opposite directions. This causes the two pins 19 to move in opposite directions and insert into the interior of the cylindrical block 13 to fix the inverter 11 as a whole, thus achieving the purpose of facilitating the installation of the inverter 11.

[0034] The mounting base 3 has a limiting groove 20 located directly below the movable plate 18 on its top. A connecting block 21 is movably connected to the inner surface of the limiting groove 20. The top of the connecting block 21 is fixedly connected to the bottom of the movable plate 18.

[0035] The design of the limiting groove 20 and the connecting block 21 serves to limit the movement of the moving plate 18, ensuring the stability of the horizontal movement of the moving plate 18.

[0036] Working principle and usage process of this utility model:

[0037] When installing the frequency converter 11, first place the frequency converter 11 on the mounting base 3 and fit the cylindrical block 13 inside the mounting block 12. Then rotate the two threaded rods 15 downwards, which will drive the two lifting plates 16 downwards. This will cause the four connecting rods 17 to rotate, which will drive the four moving plates 18 to move in opposite directions in pairs. This will cause the four pins 19 to move in opposite directions in pairs and insert into the cylindrical block 13 to fix the frequency converter 11 as a whole. This achieves the purpose of facilitating the installation of the frequency converter 11 and improving the installation efficiency of the frequency converter 11.

[0038] Due to the complex and harsh working environment in the mining area, there are many vibration sources, which makes it easy for minerals to fall from the top. At this time, starting the drive motor 4 will cause the rotating shaft 5 to drive the rectangular plate 6 to rotate, which in turn causes the two rotating rods 7 to rotate and drive the two protective plates 8 to move towards each other. When the two protective plates 8 are in contact with each other, the purpose of protecting the frequency converter 11 is achieved, avoiding the situation where minerals fall and damage the frequency converter 11 due to vibration in the mining area, and improving the service life of the frequency converter 11.
