Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, specifically a quenching device for wind turbine pitch yaw ring forgings. Background Technology

[0002] Wind turbine pitch yaw ring forgings are important load-bearing and transmission components in wind power equipment. The design of their quenching device is crucial to ensuring the performance and quality of the ring forgings. The quenching device is used to rapidly cool metal workpieces to improve their hardness, wear resistance, and fatigue resistance. In the processing of wind turbine pitch yaw ring forgings, the quenching device plays a vital role.

[0003] Patent document CN220224228U discloses an automatic cooling device for quenching annular forgings. It discloses a device comprising a base plate, a lifting mechanism at the top of the base plate, a positioning mechanism inside the lifting mechanism, two columns fixedly connected to the top of the base plate, a moving groove inside the column, a cylinder fixedly connected to the top of the column, a moving block fixedly connected to the output end of the cylinder, and a mounting plate fixedly connected between the two moving blocks. This automatic cooling device for quenching annular forgings, by activating the cylinder, extends its output end to push a connecting rod downwards, which in turn pushes the moving blocks downwards, causing the mounting plate to move downwards, until the entire annular forging is immersed in the cooling box. This allows for rapid immersion of the entire annular forging in the cooling box within a short time, achieving rapid cooling and uniform temperature reduction.

[0004] However, the automatic cooling device for quenching ring forgings in the aforementioned published literature mainly considers the ability to quickly immerse the entire ring forging in the cooling box for rapid cooling and uniform cooling. However, it is not convenient to control the water level in the quenching box to avoid damage to the electrical equipment inside the quenching box due to excessively high water levels.

[0005] Therefore, it is necessary to develop a limiting mechanism to control the water level in the quenching box and prevent damage to the electrical equipment inside the quenching box caused by excessively high water levels. Utility Model Content

[0006] The purpose of this utility model is to provide a quenching device for wind turbine pitch yaw ring forgings, so as to solve the technical problem mentioned in the background art of enabling the quenching device for wind turbine pitch yaw ring forgings to have a water level limiting function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quenching device for wind turbine pitch and yaw ring forgings, comprising: a quenching box, wherein the inner wall of the quenching box is provided with a limiting mechanism, the limiting mechanism being used to control the water level in the quenching box to prevent the water level from being too high and causing damage to the electrical equipment inside the quenching box;

[0008] The limiting mechanism includes a drain hole located on the inner wall of the quenching box. A sliding rod is installed on the inner wall of the quenching box, and a float plate is installed around the outer wall of the sliding rod. A bracket is installed on the outer wall of the quenching box, and a water collection frame is provided on the top of the bracket. A filter screen is installed on the inner wall of the water collection frame, and a fixed electric rod is installed on the outer wall of the bracket. A fixing block is installed at the output end of the fixed electric rod.

[0009] Preferably, the outer wall of the quenching box is provided with a door panel, the top of the quenching box is equipped with a liquid supply pump, the inner wall of the quenching box is equipped with a spray plate, the bottom of the spray plate is equipped with a hydraulic rod, the output end of the hydraulic rod is equipped with a placement platform, the outer wall of the quenching box is equipped with a stirring motor, the output end of the stirring motor is equipped with a stirring shaft, and the bottom of the quenching box is provided with a water outlet pipe.

[0010] Preferably, the bottom of the placement platform is provided with a receiving mechanism, which is used to receive workpieces that fall during quenching, so as to avoid the situation where the workpieces fall into the quenching box and are difficult to find.

[0011] Preferably, the receiving mechanism includes a mounting plate, which is disposed at the bottom of the placement platform.

[0012] Preferably, the outer wall of the mounting plate is provided with a fitting groove, the inner wall of the fitting groove is provided with a fitting block, and the outer wall of the fitting block is equipped with a screen basket.

[0013] Preferably, an L-shaped plate is installed at the bottom of the mounting plate, the inner wall of the L-shaped plate is provided with an adjustment groove, the inner wall of the adjustment groove is provided with an adjustment rod, and a locking block is installed on the outer wall of the adjustment rod.

[0014] Preferably, a locking block is installed on the outer wall of the screen basket.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model controls the water level in the quenching box by installing a limiting mechanism, preventing damage to the electrical equipment inside the quenching box due to excessively high water levels. Existing quenching boxes have unfixed water levels, causing the water level to rise when the workpiece enters the water, potentially damaging the electrical equipment. Therefore, this needs improvement. First, the water level is controlled by the movement of a float plate when adding water. Then, when the workpiece enters the water and the water level is high, it is drained through the drain hole, maintaining a constant water level height. Next, a water collection frame is placed on a support, and a fixed pole moves a fixing block to secure the frame. Water entering the collection frame is filtered through a filter screen for later wastewater discharge, thus preventing damage to the electrical equipment due to excessively high water levels.

[0017] 2. This utility model incorporates a receiving mechanism to catch workpieces that fall during quenching, preventing them from falling into the quenching chamber and becoming difficult to find. The workpiece is located on a placement platform, but if it is not securely fixed on the platform, it may fall into water. Therefore, this needs to be improved. First, the interlocking block on the screen basket is moved into the interlocking groove. Then, the adjusting rod is rotated to move the locking block, thus fixing the locking block and completing the installation of the screen basket. The screen basket then catches any fallen workpieces, preventing them from becoming difficult to find. Attached Figure Description

[0026] Please see Figure 1 and Figure 2 A quenching device for wind turbine pitch and yaw ring forgings includes: a quenching box 1, a door panel 2 on the outer wall of the quenching box 1, a liquid supply pump 3 installed on the top of the quenching box 1, a spray plate 4 installed on the inner wall of the quenching box 1, a hydraulic rod 5 installed at the bottom of the spray plate 4, a placement platform 6 installed at the output end of the hydraulic rod 5, a stirring motor 7 installed on the outer wall of the quenching box 1, an agitator shaft 8 installed at the output end of the stirring motor 7, and a water outlet pipe 9 at the bottom of the quenching box 1. When a workpiece is placed on the placement platform 6, the hydraulic rod 5 moves the placement platform 6 into the cooling water inside the quenching box 1. The stirring motor 7 then rotates the agitator shaft 8 to rapidly neutralize the temperature, preventing localized overheating in the water and affecting the cooling effect. Depending on the usage, the water outlet pipe 9 drains the water inside, and the spray plate 4 replaces the water with fresh cooling water for better subsequent quenching.

[0027] Please see Figure 2 and Figure 3The inner wall of the quenching box 1 is equipped with a limiting mechanism to control the water level in the quenching box 1, preventing damage to the electrical equipment inside the quenching box 1 due to excessive water level. The limiting mechanism includes a drain hole 10 located on the inner wall of the quenching box 1. A sliding rod 11 is installed on the inner wall of the quenching box 1, and a float plate 12 is installed around the outer wall of the sliding rod 11. A bracket 13 is installed on the outer wall of the quenching box 1, and a water collection frame 14 is provided on the top of the bracket 13. A filter screen 15 is installed on the inner wall of the water collection frame 14. A fixed electric rod 16 is installed on the outer wall of the bracket 13, and a fixing block 17 is installed at the output end of the fixed electric rod 16. The water level in the existing quenching box 1 is not fixed. Because the water level rises when the workpiece enters the water, potentially causing damage to electrical equipment, improvements are needed. First, the water level is controlled by the movement of the float 12 when adding water. Then, when the workpiece enters the water and the water level is high, it is drained through the drain hole 10, maintaining the water level height. Next, the water collection frame 14 is placed on the bracket 13, and the fixed pole 16 moves the fixing block 17 to secure the water collection frame 14. Water entering the water collection frame 14 is filtered through the filter screen 15 to facilitate wastewater discharge later, thus preventing damage to electrical equipment due to excessively high water levels.

[0028] Please see Figure 2 and Figure 4 The bottom of the placement platform 6 is equipped with a receiving mechanism to catch workpieces that fall during quenching, preventing them from falling into the quenching box 1 and becoming difficult to find. The receiving mechanism includes a mounting plate 18, which is located at the bottom of the placement platform 6. The outer wall of the mounting plate 18 has a fitting groove 19, and the inner wall of the fitting groove 19 has a fitting block 20. A screen basket 21 is installed on the outer wall of the fitting block 20. An L-shaped plate 22 is installed at the bottom of the mounting plate 18. The inner wall of the L-shaped plate 22 has an adjusting groove 23, and the inner wall of the adjusting groove 23 has an adjusting rod 24. The outer wall of the screen basket 21 is equipped with a locking block 25 and a locking block 26. The workpiece is located on the placement platform 6. However, if the workpiece is not fixed stably on the placement platform 6, it will fall into the water. Therefore, this needs to be improved. First, the fitting block 20 on the screen basket 21 is moved into the fitting groove 19. Then, the adjusting rod 24 is rotated to move the locking block 25, which fixes the locking block 26. This completes the installation of the screen basket 21. The screen basket 21 is then used to catch the fallen workpiece, avoiding the situation where the workpiece falls and is difficult to find.

[0029] The working principle is as follows: the workpiece is placed on the placement platform 6, then the hydraulic rod 5 moves the placement platform 6 into the cooling water inside the quenching chamber 1. The stirring motor 7 then drives the stirring shaft 8 to rotate, rapidly neutralizing the temperature and preventing localized overheating that could affect the cooling effect. Depending on usage, the water outlet pipe 9 drains the water, and the spray plate 4 replaces the water with fresh cooling water for better subsequent quenching. Currently, the water level in the quenching chamber 1 is not fixed. When the workpiece enters the water, the water level rises, potentially causing damage to electrical equipment. Therefore, this needs improvement. Firstly, the water level is controlled by the movement of the float plate 12 when adding water. Secondly, when the workpiece enters the water and the water level is high, it is drained through the drain hole 10, thus maintaining a consistently controlled water level. The water collection frame 14 is then placed on the bracket 13. The fixed pole 16 then moves the fixing block 17, thus securing the water collection frame 14. Water entering the water collection frame 14 is filtered through the filter screen 15 to facilitate wastewater discharge later, preventing damage to electrical equipment due to excessively high water levels. The workpiece is located on the placement platform 6. However, if the workpiece is not securely fixed on the placement platform 6, it may fall into the water. Therefore, this needs to be improved. First, the fitting block 20 on the screen basket 21 is moved into the fitting groove 19. Then, the adjusting rod 24 is rotated to move the locking block 25, thus securing the locking block 26. This completes the installation of the screen basket 21, which then catches any fallen workpieces, preventing them from falling and becoming difficult to find.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
