Description

Technical Field

[0001] This utility model relates to the technical field of circulating water cooling devices, and in particular to a cylindrical diesel pile hammer circulating water cooling device. Background Technology

[0002] When a cylindrical diesel pile hammer is in operation, the hammer body frequently and violently impacts the pile, generating a large amount of heat. If heat is not dissipated in time, the excessively high temperature of the hammer body can easily lead to component wear and frequent malfunctions, seriously affecting pile driving efficiency and equipment lifespan. Therefore, a circulating water cooling device is a key requirement to ensure the stable operation of the pile hammer.

[0003] Existing circulating water cooling systems for cylindrical diesel pile hammers often only have one water cooling device to cool the pile hammer, which has a limited cooling effect. When the water temperature approaches or reaches the boiling point, its heat transfer efficiency decreases significantly, which is not conducive to cooling the pile hammer. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide a circulating water cooling device for a cylindrical diesel pile hammer.

[0005] Therefore, this utility model provides a cylindrical diesel pile hammer circulating water cooling device, including a pile hammer shell, a heating box fixedly connected to the outer surface of the pile hammer shell, a connector fixedly connected to the outer surface of the heating box, a cooling box fixedly connected to the side wall of the connector, a motor fixedly connected to the lower surface of the cooling box, a first pulley fixedly connected to the output end of the motor, a first impeller fixedly connected to the end of the first pulley away from the motor, a first rotating shaft movably mounted on the lower surface of the cooling box, a second pulley fixedly connected to the lower surface of the first rotating shaft, a belt movably mounted between the first pulley and the second pulley, a third rotating shaft fixedly connected to the lower surface of the second pulley, a second impeller fixedly connected to the lower surface of the third rotating shaft, a first pipe fixedly connected to the lower surface of the heating box, a second pipe fixedly connected to the end of the first pipe away from the heating box, the second pipe being a spiral pipe, and the second pipe being sleeved on the outer surface of the second impeller.

[0006] Preferably, a support frame is fixedly connected to the side wall of the cooling box, the side wall of the support frame is provided with a groove, a limiting groove is provided on the lower surface of the support frame, and a limiting disk is fixedly connected to the lower surface of the second impeller, the limiting disk being located inside the limiting groove.

[0007] Preferably, a first connecting block is fixedly connected to the inner wall of the support frame, a sealing shell is fixedly connected to the end of the first connecting block away from the support frame, the first impeller is located inside the sealing shell, and a second pipe is fixedly connected to the water inlet end of the sealing shell.

[0008] Preferably, a second connecting block is fixedly connected to the inner wall of the support frame, and a stabilizing frame is fixedly connected to the side wall of the second connecting block, with the stabilizing frame sleeved on the outer surface of the third rotating shaft.

[0009] Preferably, a third pipe is fixedly connected to the water outlet end of the sealing shell, and the end of the third pipe away from the sealing shell is fixedly connected to the lower surface of the cooling box.

[0010] Preferably, a fourth pipe is fixedly connected to the outer surface of the heating box, and the end of the fourth pipe away from the heating box is fixedly connected to the outer wall of the cooling box.

[0011] Preferably, a first heat-absorbing plate is fixedly connected to the outer surface of the heated box, and a first heat-dissipating fin is fixedly connected to the outer surface of the first heat-absorbing plate, wherein there are multiple first heat-dissipating fins.

[0013] This utility model provides a cylindrical diesel pile hammer circulating water cooling device, which has the following beneficial effects:

[0014] Compared with existing technologies, this cylindrical diesel pile hammer circulating water cooling device consists of a motor, a first pulley, a first impeller, a heating box, a second pipe, a sealing shell, a belt, a second pulley, a third shaft, and a second impeller. When the water cooling device needs to operate, the motor drives the first pulley to rotate, which in turn drives the first impeller to rotate. This allows high-temperature water from the heating box to be drawn into the sealing shell through the first and second pipes. Simultaneously, the rotation of the first pulley drives the belt and the second pulley to rotate, which in turn drives the third shaft and the second impeller to rotate. The second impeller then circulates air through the second pipe. The cooling system achieves initial cooling of the high-temperature water. Combined with its own water cooling device, the cooling effect can be improved. Compared with existing circulating water cooling devices, which often only have one water cooling device to cool the pile hammer, the cooling effect is limited. When the water temperature approaches or reaches the boiling point, its heat transfer efficiency decreases significantly, which is not conducive to cooling the pile hammer. This cylindrical diesel pile hammer circulating water cooling device adds a second impeller to the water cooling system to provide air cooling for the second pipe. The combined work of air cooling and water cooling can more effectively dissipate heat from the high-temperature water, improve the overall heat dissipation efficiency of the device, and help cool the pile hammer.

The end of the first pipe 13 away from the heating box 2 is fixedly connected to the second pipe 14. The second pipe 14 is a spiral pipe, which can increase the heat dissipation area of ​​the second pipe 14 and make the heat dissipation effect of the second pipe 14 better. When the water cooling device needs to work, the motor 5 drives the first pulley 6 to rotate, which in turn drives the first impeller 7 to rotate. This allows the high-temperature water in the heating box 2 to be drawn into the sealing shell 15 through the first pipe 13 and the second pipe 14. At the same time, the rotation of the first pulley 6 can drive the belt 10 and the second pulley 9 to rotate, which in turn drives the third rotating shaft 11 and the second impeller 12 to rotate. The second impeller 12 can then perform air cooling on the second pipe 14 to achieve a preliminary cooling effect on the high-temperature water. Combined with its own water cooling device, the cooling effect can be improved. The second pipe 14 is sleeved on the outer surface of the second impeller 12.

[0028] Depend on Figures 1-10As shown, this utility model provides a cylindrical diesel pile hammer circulating water cooling device. A support frame 23 is fixedly connected to the side wall of the cooling tank 4. The support frame 23 provides an installation position for the motor 5 and the first rotating shaft 8, and also provides support for the second impeller 12. A groove 24 is provided on the side wall of the support frame 23, and a limit groove 21 is provided on the lower surface of the support frame 23. A limit plate 22 is fixedly connected to the lower surface of the second impeller 12. The limit plate 22 and the limit groove 21 cooperate to provide good support and limit for the second impeller 12, reducing the possibility of the second impeller 12 shaking during rotation. The limit plate 22 is located inside the limit groove 21. A first connecting block 18 is fixedly connected to the inner wall of the support frame 23. The first connecting block 18 is located away from the support frame 23. A sealing shell 15 is fixedly connected to the end of the first impeller 7, which is located inside the sealing shell 15. A second pipe 14 is fixedly connected to the water inlet end of the sealing shell 15. A second connecting block 19 is fixedly connected to the inner wall of the support frame 23. The second connecting block 19 cooperates with the stabilizing frame 20 to limit the movement of the third rotating shaft 11, reducing the possibility of shaking during rotation. A stabilizing frame 20 is fixedly connected to the side wall of the second connecting block 19 and is fitted onto the outer surface of the third rotating shaft 11. A third pipe 16 is fixedly connected to the water outlet end of the sealing shell 15. The end of the third pipe 16 away from the sealing shell 15 is fixedly connected to the lower surface of the cooling box 4. The motor 5 drives the first pulley 6 to rotate, which in turn drives the first impeller 7 to rotate, thereby cooling the heated water. High-temperature water in box 2 is drawn into sealed shell 15 through first pipe 13 and second pipe 14. The first impeller 7 continues to rotate, transporting the water in sealed shell 15 to cooling box 4 through third pipe 16. The water in cooling box 4 is further cooled by second heat-absorbing plate 27 and second heat dissipation fins 28. Simultaneously, the cooled water enters fourth pipe 17 from cooling box 4 during the continuous operation of first impeller 7, ultimately entering heating box 2 for further heating, achieving the effect of circulating water cooling. Fourth pipe 17 is fixedly connected to the outer surface of heating box 2, with one end of fourth pipe 17 fixedly connected to the outer wall of cooling box 4. First heat-absorbing plate 25 is fixedly connected to the outer surface of heating box 2. The water inside heating box 2 is heated, and the temperature is transferred... The heat is transferred to the first heat-absorbing plate 25, which then transfers it to the first heat-dissipating fins 26. Finally, the first heat-dissipating fins 26 dissipate some of the heat from the heated chamber 2, lowering its temperature. Multiple first heat-dissipating fins 26 are fixedly connected to the outer surface of the first heat-absorbing plate 25. A second heat-absorbing plate 27 is fixedly connected to the side wall of the cooling chamber 4, and second heat-dissipating fins 28 are fixedly connected to its side wall. The second heat-absorbing plate 27 can further absorb the temperature of the initially cooled water in the cooling chamber 4 and transfer this temperature to the second heat-dissipating fins 28, which then dissipate it into the air, further cooling the liquid in the cooling chamber 4.The number of second heat dissipation fins 28 is multiple.
