Description

Technical Field

[0001] This utility model relates to the field of propeller processing technology, and in particular to a propeller heat treatment device. Background Technology

[0002] A propeller is a device that converts the rotational power of an engine into propulsion. It mainly propels an aircraft or ship forward by generating a reaction force through the rotation of blades in air or water. A propeller consists of multiple blades and a central hub. When it is driven to rotate by an engine, the inclined surfaces of the blades push the fluid (air or water) backward, thereby obtaining a reaction force, i.e., propulsion.

[0003] During propeller production, heat treatment is required to increase the overall hardness of the propeller material. When using a solution treatment chamber, the propeller is typically placed directly into the chamber for heating. After heating, it is lifted by a tower crane or gantry crane and transferred to a cooling chamber for cooling. However, since the propeller is already at a high temperature after heat treatment, ensuring sufficient contact between the lifting equipment and the propeller is crucial when transferring it using a gantry crane. Since only the central shaft hole of the propeller provides adequate support, this causes inconvenience during unloading and transfer. Therefore, we propose a propeller heat treatment device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a propeller heat treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a propeller heat treatment device is designed, including a base, a solution tank is provided above one end of the base, and support frames are installed on both sides of the bottom of the solution tank, with the support frames fixed on the base.

[0006] An inlet and outlet are provided at one end of the solution tank, and strip grooves are provided on both sides of the bottom of the solution tank. The strip grooves are arranged along the length of the solution tank and one end of them passes through the inlet and outlet.

[0007] A travel guide rail is provided below the strip groove. The travel guide rail is fixed on the base. A travel trolley is installed on the travel guide rail. The travel trolley corresponds to the strip groove and is equipped with a support plate. The support plate corresponds to the bottom of the solid solution box. Sleeves are vertically installed at the top corners of the support plate.

[0008] A crossbeam is installed at both ends of the upper part of the support plate. Support columns are installed at the bottom of both ends of the crossbeam. The bottom of the support columns is placed in the sleeve. A longitudinal beam is provided at both ends between the two crossbeams. The ends of the longitudinal beams are fixed to the crossbeams. A hanging chain is provided at the center of the bottom of the two longitudinal beams. The two hanging chains are connected by a lock.

[0009] Preferably, heating components are installed on the top and both sides inside the solution treatment chamber.

[0010] Preferably, a connecting rod is provided at both ends between the two longitudinal beams, and the end of the connecting rod is fixed to the longitudinal beam.

[0011] Preferably, the surfaces of the support plate, the sleeve, the support column, the crossbeam, the longitudinal beam, the hanging chain, the buckle, and the connecting rod are all covered with a high-temperature resistant coating.

[0012] Preferably, the end of the chain away from the buckle is detachably mounted on the connecting seat, and the connecting seat is fixed at the bottom center of the longitudinal beam.

[0013] Preferably, a sealing plate is installed at the end of the support plate away from the solution tank, the sealing plate corresponds to the inlet and outlet, and a sealing seat is installed on the side of the sealing plate close to the solution tank, the sealing seat corresponds to the inner wall of the solution tank.

[0014] Preferably, pressure plates are provided on both sides of the solution tank near the inlet and outlet. A rotating seat is installed in the middle of the side of the pressure plate near the solution tank. A rotating shaft is connected to the end of the rotating seat. The other end of the rotating shaft is rotatably installed on a fixed seat. The fixed seat is fixed to the outer wall of the solution tank. An inclined pushing mechanism is provided on the outside of the solution tank. The end of the pushing mechanism is rotatably installed in a U-shaped seat. One U-shaped seat is fixed to the side of the pressure plate, and the other U-shaped seat is fixed to the outer wall of the solution tank.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application:

[0016] 1. The propeller heat treatment equipment is installed by inserting a support column into the sleeve. The lifting device can be directly hung on the longitudinal beam or connecting rod, thereby lifting and removing the propeller that is fixed on the lifting chain, and then transporting it to the cooling box for cooling. This provides a more convenient fulcrum for the gantry crane to lift and transport the propeller, and facilitates the handling of the propeller.

[0017] 2. The propeller heat treatment equipment uses a pressure plate that flips under the action of a pushing mechanism to press against the sealing plate placed at the inlet and outlet, thereby improving the airtightness of the entire solution treatment chamber and reducing the outward loss of heat from the solution treatment chamber, thus achieving energy saving.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A propeller heat treatment device includes a base 1, a solution tank 2 is provided above one end of the base 1, and support frames 3 are installed on both sides of the bottom of the solution tank 2, and the support frames 3 are fixed on the base 1.

[0025] Heating components 18 are installed on the top and both sides of the solution bath 2 to increase the temperature inside the solution bath 2, thereby heating the workpiece placed inside the solution bath 2.

[0026] like Figure 1 and Figure 2 As shown, an inlet / outlet 4 is provided at one end of the solution bath 2, and strip grooves 5 are provided on both sides of the bottom of the solution bath 2. The strip grooves 5 are arranged along the length of the solution bath 2 and one end of them passes through the inlet / outlet 4 to facilitate the entry and exit of the workpiece in the solution bath 2.

[0027] A travel guide rail 6 is provided below the strip groove 5. The travel guide rail 6 is fixed on the base 1. A travel trolley is installed on the travel guide rail 6. The travel trolley corresponds to the strip groove 5 and is equipped with a support plate 7. The support plate 7 corresponds to the bottom of the solution box 2, so that the support plate 7 can move linearly back and forth along the travel guide rail 6, so that the support plate 7 can extend into the solution box 2 under the drive of the travel trolley.

[0028] In use, sleeves 8 are vertically installed at the top corners of the support plate 7. Crossbeams 10 are installed at both ends of the support plate 7, and support columns 9 are installed at the bottom of both ends of the crossbeams 10. The bottom of the support columns 9 is placed inside the sleeves 8. Longitudinal beams 11 are provided at both ends between the two crossbeams 10, with the ends of the longitudinal beams 11 fixed to the crossbeams 10. Hanging chains 13 are provided at the center of the bottom of both longitudinal beams 11, and the two hanging chains 13 are connected by a buckle 14. The propeller is placed on the support plate 7, and then one hanging chain 13 is passed through the shaft hole of the propeller. The two hanging chains 13 are connected using the buckle 14, thus suspending and fixing the propeller to the hanging chains 13. In actual use, the buckle 14 is a carabiner.

[0029] The end of the hanging chain 13 away from the buckle 14 is detachably installed on the connecting seat 12, and the connecting seat 12 is fixed at the bottom center of the longitudinal beam 11, which facilitates the disassembly, assembly and replacement of the hanging chain 13.

[0030] Specifically, after the propeller is fixed, the trolley starts and sends the support plate 7 into the solution bath 2, then begins to heat the propeller. As the support plate 7 extends into the solution bath 2, as... Figure 1 and Figure 3 As shown, a sealing plate 16 is installed at the end of the support plate 7 away from the solution tank 2. The sealing plate 16 corresponds to the inlet and outlet 4. A sealing seat 17 is installed on the side of the sealing plate 16 close to the solution tank 2. The sealing seat 17 corresponds to the inner wall of the solution tank 2 and can seal the solution tank 2, thereby sealing the solution tank 2 and ensuring that the solution tank 2 is always in a high-temperature state.

[0031] After the sealing plate 16 is placed on the solution tank 2, pressure plates 19 are provided on both sides of the solution tank 2 near the inlet and outlet 4. A rotating seat 20 is installed in the middle of the side of the pressure plate 19 near the solution tank 2. The end of the rotating seat 20 is connected to a rotating shaft 21. The other end of the rotating shaft 21 is rotatably installed on a fixed seat 22. The fixed seat 22 is fixed on the outer wall of the solution tank 2. An inclined pushing mechanism 23 is provided on the outside of the solution tank 2. The end of the pushing mechanism 23 is rotatably installed in a U-shaped seat 24. One U-shaped seat 24 is fixed on the side of the pressure plate 19, and the other U-shaped seat 24 is fixed on the outer wall of the solution tank 2. In actual use, the pushing mechanism 23 is a hydraulic cylinder. The pushing mechanism 23 will push the pressure plate 19 to rotate around the rotating shaft 21, so that the pressure plate 19 presses on the side of the sealing plate 16 away from the inlet and outlet 4, thereby improving the sealing effect of the sealing plate 16 on the inlet and outlet 4.

[0032] After the propeller has been heat-treated, the support plate 7 is sent out of the solution tank 2 by a traveling trolley. Then, a gantry crane is used to bring the lifting device close to the longitudinal beam 11. There are connecting rods 15 at both ends between the two longitudinal beams 11. The ends of the connecting rods 15 are fixed to the longitudinal beams 11, so that the lifting device can be fixed on the connecting rods 15 or the longitudinal beams 11, thereby lifting the propeller up and down and sending it into the cooling box for cooling. This facilitates the installation of the propeller when the lifting device is used to lift it.

[0033] It should be noted that the surfaces of the support plate 7, the sleeve 8, the support column 9, the crossbeam 10, the longitudinal beam 11, the hanging chain 13, the lock 14, and the connecting rod 15 are all covered with a high-temperature resistant coating.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
