Description

Compressor fixing mechanism of locomotive air conditioner

technical field

The utility model relates to a novel fixing mechanism, which is mainly used in compressors of locomotive air conditioners.

Background technique

At present, locomotive air conditioners are widely used in trains, urban light rail trains, station wagons and military vehicles to adjust the air temperature in the compartments to provide a comfortable travel environment. The internal system components of the existing locomotive air conditioner all adopt an anti-seismic fixed structure to cope with the impact and damage to the air conditioner components caused by the high-speed operation of the locomotive and the bumpy road.

For example, the prior patent that discloses the following content, the patent number is 97208944, and the name is a vibration damping device for an air conditioner. The solution is to install a vibration absorber in the tangential direction of the rotary compressor. The vibration absorber is composed of a spring and a mass connected to the spring. . To solve the problem of fatigue fracture at the connection between the piping and the compressor. Most of the vibration energy of the compressor is transferred to the vibration absorber to reduce the vibration amplitude of the vibration source of the compressor, and the vibration of the vibration absorber will not affect the vibration and noise performance of the air conditioner.

Above existing compressor damping device is not suitable for locomotive air conditioner. Since the mass block connected by the shock absorber and the spring is not fastened to the compressor, when running at high speed or on a bumpy road, the compressor itself will vibrate violently and cause the internal structure to break and overturn, which will cause The damage of the compressor may affect the normal circulation of the refrigerant in the system pipeline. At the same time, the above-mentioned damping device has a large volume, which also limits the miniaturization design of the locomotive air conditioner, and is not conducive to the installation and commissioning of the whole machine.

Utility model content

The compressor fixing mechanism of the locomotive air conditioner described in the utility model is designed to solve the above problems and deficiencies by adopting fixed structures on both sides of the bottom and both sides of the top, along the position where the compressor is placed horizontally and the direction of the refrigerant pipeline. To achieve multi-directional limit, so as to absorb vibration energy to the greatest extent, reduce the amplitude of resonance, and ensure that the internal structure of the compressor maintains stable operation under severe oscillating vehicle conditions.

The locomotive air conditioner using the compressor fixing mechanism of the utility model adopts a horizontal rotary compressor.

The fixing method adopted is that two groups of fixing brackets are arranged in the longitudinal direction of the compressor, and each fixing bracket is connected with the bottom plate of the locomotive air conditioner through fixing columns on both sides.

The fixing bracket fixes the compressor on the base plate from front to back. The inlet and outlet system pipes connected to the compressor pass through above the fixing bracket.

In order to avoid the shock and damage to the compressor caused by the high-speed running of the locomotive or the bumpy road, the further improvement of the utility model is that the fixed structure also includes several hoop rings, and the hoop rings surround the back of the compressor. Moreover, the ends on both sides of the hoop ring are connected with the bottom plate through fixing bolts.

The compressor shell and hoop ring are usually made of metal. In order to ensure the tight connection between the hoop ring and the compressor shell, the hoop ring will not cause excessive impact on the compressor when the locomotive is running at high speed or the road is bumpy. Several buffer rubber pads can be arranged on the inner side of the clamp ring, and fastening bolts are arranged on the outer surface of the clamp ring, and the fastening bolts penetrate through the clamp ring to press the buffer rubber pads against the outside of the compressor housing.

As mentioned above, the advantage of the compressor fixing mechanism of the locomotive air conditioner of the utility model is that the horizontal placement of the compressor takes up little space, and the fixing on both sides of the bottom and top of the compressor can absorb vibration energy to the maximum extent, ensuring The compressor and the fixing mechanism remain relatively static, thereby effectively ensuring the normal operation of the compressor under severe oscillating vehicle conditions.
