Description

Technical Field

[0001] This utility model relates to the field of steel pipe cooling technology, and in particular to a high-strength special-shaped pipe cooling device for large-scale cranes. Background Technology

[0002] Quenching is a common process for significantly improving the overall performance of steel pipes at a relatively low cost. In current industrial production, there are two main quenching cooling methods: external spraying and internal rinsing cooling, and immersion cooling in a quenching tank.

[0003] External spray cooling involves simultaneously spraying water onto the heated outer wall of a steel pipe and simultaneously spraying high-speed water onto the inner wall of the pipe from the pipe ends, thus cooling both the inner and outer walls simultaneously. However, this method suffers from a drawback: the upper part of the pipe blocks the incoming cooling water, preventing heat exchange between the lower part and the water. The rapid cooling of the upper part and the slow cooling of the lower part result in inconsistent performance uniformity throughout the pipe, potentially leading to substandard performance. Therefore, a solution for a high-strength, non-standard pipe cooling device for large mobile cranes is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-strength special-shaped pipe cooling device for large mobile cranes, which solves the problem of inconsistent performance of the entire steel pipe due to rapid cooling of the upper part and slow cooling of the lower part during the spraying process.

[0005] This utility model also provides a high-strength special-shaped pipe cooling device for large mobile cranes, comprising a spray box, an opening on the left side of the spray box, a support plate fixedly connected to the opening, a filter box inside the spray box, an installation plate fixedly connected to the side of the filter box near the opening, a rotating rod fixedly connected to the installation plate, one end of the rotating rod passing through the installation plate and rotatably connected to the support plate, the other end of the rotating rod passing through the spray box and fixedly connected to a driven wheel, a drive motor fixedly connected to the right side of the spray box, a drive wheel fixedly connected to the output end of the drive motor, the drive wheel meshing with the driven wheel, a spray plate fixedly connected to the spray box above the filter box, several nozzles provided on the lower side of the spray plate, and a conveying pipe fixedly connected to the rear side, the other end of the conveying pipe fixedly connected to a water tank, the water tank being located at the bottom of the spray box.

[0006] A filter screen is slidably connected inside the water tank, and heat dissipation fins are fixedly connected inside the water tank below the filter screen. The heat dissipation fins are arranged alternately, and some are located on the left and right sides of the spray box.

[0007] The delivery pipe is configured as a three-pipe system, with a water pump fixedly connected to one end inside the water tank.

[0008] The spray box has a hinged door on the front side.

[0009] The filter box is rectangular in shape and can be rotatably connected to the spray box.

[0010] This utility model has the following beneficial effects:

[0011] 1. By installing a drive motor and spray plates on the spray box, the drive motor drives the filter box to rotate through the drive wheel and driven wheel during operation, thereby driving the steel pipe to rotate, so that it is cooled evenly and the effect is better.

[0012] 2. By installing a filter screen and heat dissipation fins on the water tank inside the spray box, impurities in the water are filtered out by the filter screen to prevent clogging of the water pump. At the same time, the cooling water slides into the water tank in an S-shape under the action of the heat dissipation fins, so as to dissipate heat quickly. Attached Figure Description

An opening 2 is provided on the left side of the spray box 1, and a support plate 3 is fixedly connected inside the opening 2. A filter box 4 is provided inside the spray box 1, which is also rectangular in shape and rotatably connected to the spray box 1. An mounting plate 41 is fixedly connected to the side of the filter box 4 near the opening 2. A rotating rod 42 is fixedly connected to the mounting plate 41. One end of the rotating rod 42 passes through the mounting plate 41 and is rotatably connected to the support plate 3. The other end of the rotating rod 42 passes through the spray box 1 and is fixedly connected to a driven wheel 9. A drive motor 8 is fixedly connected to the right side of the spray box 1. A drive wheel 81 is fixedly connected to the output end of the drive motor 8, and the drive wheel 81 meshes with the driven wheel 9. The drive motor 8 drives the filter box 4 to rotate through the drive wheel 81 and the driven wheel 9, thereby causing the steel pipe to rotate.

[0021] A spray plate 6 is fixedly connected inside the spray box 1 located on the upper side of the filter box 4. Several nozzles 61 are provided on the lower side of the spray plate 6, and a conveying pipe 7 is fixedly connected to the rear side. The other end of the conveying pipe 7 is fixedly connected to a water tank 5. The water tank 5 is located at the bottom of the spray box 1. A door 10 is hinged to the front side of the spray box 1, which facilitates the cleaning of the filter screen 51. The filter screen 51 is slidably connected inside the water tank 5. Heat dissipation fins 52 are fixedly connected inside the water tank 5 located below the filter screen 51. The heat dissipation fins 52 are arranged alternately, and some are located on the left and right sides of the spray box 1. Under the action of the heat dissipation fins 52, the cooling water slides into the water tank 5 in an S-shape, so as to dissipate heat quickly. The conveying pipe 7 is a one-to-three arrangement, and a water pump is fixedly connected to one end inside the water tank 5.

[0022] When in use, first start the water pump. Under the action of the water pump and the delivery pipe 7, the cooling water in the water tank 5 is delivered to the spray plate 6. Then, the steel pipe is placed into the filter box 4 from the opening 2, and the drive motor 8 is started. The drive motor 8 drives the filter box 4 to rotate through the drive wheel 81 and the driven wheel 9, thereby driving the steel pipe to rotate, so that it is cooled evenly and the effect is better.
