[0028] Embodiment 2:

[0029] Reference Figure 1 and Figure 4 , a ship diesel engine crankshaft repair equipment, which is basically the same as Example 1, and further, a cooling device 10 is arranged on the inner wall of the bracket 3, and the cooling device 10 includes a water tank 101, the bottom of the water tank 101 is fixedly connected to the inner wall of the bracket 3, a water pipe 102 is fixedly penetrated on the side of the water tank 101, and a water storage air bag 103 is fixedly penetrated on the end of the water pipe 102 away from the water tank 101, a flushing pipe 104 is fixedly penetrated on the side of the water storage air bag 103, and a nozzle 105 is fixedly penetrated on the end of the flushing pipe 104 away from the water storage air bag 103, and a stabilizing plate 106 is fixedly connected to the circumferential surface of the flushing pipe 104, a pushing plate 107 is fixedly connected to the side of the fixed vertical plate 85, and an L-shaped plate 108 is fixedly connected to the side of the pushing plate 107.

[0032] Specifically, when the ship diesel engine crankshaft repair equipment is working / in use: when in use, the crankshaft is placed above the placement table 87, and then the servo motor 82 is turned on. After the servo motor 82 is turned on, the output shaft of the servo motor 82 drives the two-way reciprocating screw 83 to rotate.

After the water storage airbag 103 is squeezed by the L-shaped plate 108, the water inside the water storage airbag 103 flows into the inside of the flushing pipe 104 with the squeezing of the L-shaped plate 108. After the water enters the inside of the flushing pipe 104, the water flows through the flushing pipe 104 to the inner wall of the nozzle 105. Then, the water flows through the nozzle 105 to the crankshaft above the placement table 87, thereby achieving the effect of cooling the crankshaft of the ship diesel engine, so that the ship diesel engine crankshaft repair equipment can effectively reduce the temperature.
