Description

Technical Field

[0001] The utility model relates to the technical field of frequency converter components, in particular to a main control board installation device. Background Art

[0002] The frequency converter is an electric power control device that applies frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, microprocessor unit, etc. The frequency converter adjusts the output power voltage and frequency by the opening and closing of the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency converter also has many protection functions, such as over-current, over-voltage, overload protection, etc. With the continuous improvement of industrial automation, frequency converters have also been widely used.

[0003] Traditional frequency converters mainly include a main control board and a shell for installing the main control board. When the frequency converter is used underground in a coal mine, the underground environment is usually high or low temperature, high humidity, and dusty. The use environment is relatively complex and harsh. The main control board usually needs to meet environmental requirements such as moisture-proof, dust-proof, anti-static, and anti-vibration. The existing main control board in the frequency converter is usually hard-connected directly to the frequency converter shell using a large number of screws, which makes the main control board inconvenient to load and unload. The main control board is easily damaged during loading and unloading, thereby reducing the stability of the frequency converter quality.

[0005] However, the above technical solution still has at least the following defects: when used underground in a coal mine, due to the violent vibration of the equipment in the coal mine, the main control board in the above technical solution lacks the necessary hard connection, which causes the main control board to be easily shaken and damaged during violent vibrations, and even fall off in severe cases, and the installation stability is low (convenient and stable installation, screws and copper columns), and the impact resistance to violent vibrations is poor, which causes the components of the main control board to be easily damaged during vibrations, and the seismic performance is difficult to meet production needs (seismic performance, pads and baffles).

[0036] Depend on Figures 1 to 9 It is given that some embodiments of the utility model relate to a main control board installation device, which is installed on a main control board body 1, comprising:

[0037] The bearing assembly includes a bearing plate 2 and a mounting platform 3. The mounting platform 3 is formed on the upper surface of the bearing plate 2. The mounting platform 3 is used to place the main control board body 1 and to position the main control board body 1 directly above the bearing plate 2.

[0039] In a further embodiment, the material of the utility model can be high-strength engineering plastics such as POM and PPS, and the bearing assembly can be integrally formed, wherein the bearing plate 2 is matched with the main control board body 1 .

[0040] In these embodiments, the main control board body 1 can be stably installed by the bearing assembly, and the main control board body 1 is placed on the installation platform 3 to ensure that the main control board body 1 can be accurately installed on the bearing plate 2. The cooperation between the bearing plate 2 and the installation platform 3 ensures that the main control board body 1 is safely and stably installed. The main control board body 1 can be firmly fixed on the installation platform 3 through the cooperation of the fastening assembly. With the coordinated cooperation of the connecting piece 4 and the installation piece 5, the main control board body 1 can be quickly and accurately installed and fixed, and the loading and unloading is more convenient and flexible, which not only ensures the stability of the main control board body 1 in use, but also avoids damage caused by severe damage.

The placement area 31 is used to fit the edge of the main control board body 1 , and the positioning area 32 is used to position the main control board body 1 on the installation platform 3 .

[0051] In these embodiments, the placement area 31 and the positioning area 32 are combined to form a frame-shaped installation platform 3. When the main control board body 1 is installed, the main control board body 1 is fit against the installation platform 3. Through the cooperation of the placement area 31 and the positioning area 32, not only can the main control board body 1 be installed efficiently and accurately, but it is also beneficial to improve the stability of the installation.
