[0016] Example:

[0017] like Figure 1 , Figure 2 and Figure 3 The present embodiment provides a common base for a diesel generator set, including a group of cross beams 1 and a group of end beams 2. The end beams are U-shaped plates. The end beams are connected to the cross beams by bolts. The cross beams are provided with multiple groups of mounting holes 3. The cross beams are provided with an oil engine beam 4 and a motor beam 5. The oil engine beam and the motor beam are both outward-turned bending structures. The oil engine beam and the motor beam are connected to the cross beam by bolts. Oil engine support frames 6 are provided on both sides of the oil engine beam, and motor support frames 7 are provided on both sides of the motor beam. A first vibration sensor 8 is provided in the middle of the oil engine beam, and a second vibration sensor 9 is provided in the middle of the motor beam. The oil engine support frame is a square tube structure. The motor support frame is an outward-turned bending structure. A group of hoisting blocks 10 are provided on one side of the cross beam. The connecting bolts between the cross beam and the end beam, the connecting bolts between the oil engine beam and the cross beam, and the connecting bolts between the motor beam and the cross beam all use bolts with a diameter of 12 mm, and the nuts are self-locking nuts.

[0018] Considering that there are many types of engines and motors, the center of gravity and installation position are different, which makes the position of the base different during welding, greatly reducing the work efficiency. This embodiment selects appropriate mounting holes according to the size and weight of the motor and the oil engine, uniformly uses bolts with a diameter of 12mm, and self-locking nuts are used to prevent loosening. A vibration sensor is installed to monitor the vibration intensity of the unit and the loosening of the unit bolts caused by excessive vibration, and timely feedback the excessive vibration situation to the unit control unit through the output end to prompt the staff to carry out maintenance in time.

[0019] The public base of this embodiment eliminates the welding process, has high assembly efficiency, and the base materials can be pre-processed in large quantities and can be directly installed when used, which greatly improves the production efficiency of the enterprise.

[0020] The utility model provides a concept and method for a common base of a diesel generator set. There are many methods and ways to implement the technical solution. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications should also be regarded as the protection scope of the utility model. All components not specified in this embodiment can be implemented by existing technologies.
