Description

Technical Field

[0001] This invention relates to the field of wind turbine ring component processing technology, and in particular to a heating device for cylindrical blanks of wind turbine ring components and its implementation method. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current.

[0003] In the manufacturing and processing of wind turbine components inside wind turbines, it is often necessary to heat the cylindrical blanks as a whole. Related patents exist; for example, publication number CN208210358U discloses a heating device for irregularly shaped blanks with uniform temperature distribution. This device includes two opposing copper electrodes, with the irregularly shaped blank clamped between them. The copper electrodes are connected to the two poles of an adjustable DC power supply, forming a closed loop with the two copper electrodes and the irregularly shaped blank. One or more induction coils are arranged around the irregularly shaped blank, and these coils are connected to an adjustable AC power supply. This patent allows blanks with uneven cross-sectional areas to quickly achieve a uniform temperature distribution. The heating device uses a combination of conductive heating and induction heating. The central part is heated by conductive heating, while the outer parts with different cross-sectional areas are heated by induction heating with AC current of different frequencies. The structure is simple, the operation is convenient, and the size of the device can be adjusted according to the blank size, making it highly versatile.

[0004] In practice, this patent still has the following problems:

[0005] 1. When heating the billet, the heat source releases heat in a diffuse manner, which easily leads to the loss of most of the heat and reduces the energy utilization rate when heating the billet.

[0006] 2. During the heating process, it is often difficult to observe the heating status of the billet. Generally, the equipment is equipped with an observation window, but the observation window can only observe a relatively close area. It is often difficult to observe and operate inside the equipment, making it difficult to control the heating status of the billet.

[0007] 3. When loading and unloading columnar billets, their columnar shape often makes them easy to roll, which makes loading and unloading troublesome and affects the overall processing efficiency. Summary of the Invention

[0008] The purpose of this invention is to provide a heating device for cylindrical blanks of wind turbine components and its implementation method, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a heating device for cylindrical billets of wind turbine components, comprising a body and a cylindrical billet, wherein a fan is provided on the top of the body, a heating component is provided inside the body, the cylindrical billet is placed inside the heating component, an inlet is provided on the front of the body, the position and number of the inlet are matched with the heating component, a pin bracket is provided on one side of the inlet, the position and number of the pin bracket are matched with the heating component, and a connecting rod is provided above the heating component;

[0010] The heating component is provided with a first heating position, a second heating position, a third heating position and a fourth heating position. A transmission component is provided at the bottom of the machine body. The first heating position, the second heating position, the third heating position and the fourth heating position are all connected to the transmission component.

[0011] Furthermore, the first heating position, the second heating position, the third heating position, and the fourth heating position have the same overall structure, and are connected by a linkage.

[0012] Furthermore, the first heating position includes a first conveyor roller, a second conveyor roller, a spiral pattern, a connecting end, a heating tube, a reflector, a moving shaft, a hinge end, and a connecting tube. The first and second conveyor rollers are arranged in parallel. Both ends of the first and second conveyor rollers are rotatably connected to the machine body through the connecting end. The outer sides of the first and second conveyor rollers are provided with spiral patterns. A heating tube is provided above the first and second conveyor rollers. One end of the heating tube is connected to the machine body through the connecting tube. A reflector is provided above the heating tube. The bottom of one side of the reflector is connected to a pin bracket through a pin. A moving shaft is provided at the top of the reflector. Both ends of the moving shaft are set as connecting ends, and the connecting ends are connected to a connecting rod through pins.

[0013] Furthermore, the cylindrical blank is positioned above the first conveying roller and the second conveying roller.

[0014] Furthermore, a device cavity is provided on one side of the machine body, and a first motor is installed inside the device cavity. A rotating rod is fixedly connected to the output shaft of the first motor. The end of the rotating rod away from the output shaft of the first motor is slidably disposed inside the slide rail. A connecting rod is connected to the end of the rotating rod away from the output shaft of the first motor through a shaft pin. A through hole is provided on one side of the device cavity, and the end of the connecting rod away from the rotating rod passes through the through hole and is connected to the connecting rod through a shaft pin. An electric heating tube is connected to one side of the device cavity and is disposed below the fan.

[0015] Furthermore, the transmission assembly includes a first gear, a second gear, a three-ring gear, a second motor, a first chain belt, a second chain belt, and a main chain belt. Four three-ring gears are provided, and they are connected to each other via the main chain belt. Each three-ring gear is positioned below the first heating position, the second heating position, the third heating position, and the fourth heating position. Above each three-ring gear is a first gear and a second gear. The central shaft of the first gear is fixedly connected to the connecting end of the first conveyor roller, and the first gear is connected to the three-ring gear via the first chain belt. The central shaft of the second gear is fixedly connected to the connecting end of the second conveyor roller, and the second gear is connected to the three-ring gear via the second chain belt. A second motor is located behind each three-ring gear, and the output shaft of the second motor is fixedly connected to the central shaft of the three-ring gear.

[0016] Furthermore, the three-ring gear includes a first gear ring, a second gear ring, a third gear ring, and a partition plate. Two partition plates are provided, which are respectively disposed between the first gear ring, the second gear ring, and the third gear ring. The first chain belt is sleeved on the outside of the first gear ring, the second chain belt is sleeved on the outside of the second gear ring, and the main chain belt is sleeved on the outside of the third gear ring.

[0017] Another technical problem to be solved by the present invention is to provide an implementation method for a heating device for cylindrical billets of wind turbine components, comprising the following steps:

[0018] Step 1: Turn on the fan, heating element, and electric heating element to preheat the inside of the machine;

[0019] Step 2: Start the second motor. The second motor drives each three-ring gear to rotate. The three-ring gear drives the first gear and the second gear to rotate through the first chain belt and the second chain belt. The first conveyor roller and the second conveyor roller rotate. At the same time as the first conveyor roller and the second conveyor roller rotate, the spiral rotates synchronously. The rotation of the spiral rotates to feed the cylindrical blank.

[0020] Step 3: The cylindrical billet is placed above the first and second conveyor rollers. The heating tubes work to heat the cylindrical billet. During the heating process, the reflector reflects the heat, improving the heating efficiency of the cylindrical billet.

[0021] Step 4: After heating is complete, start the second motor, and use the first and second conveyor rollers to drive the spiral to rotate and unload the heated cylindrical blank.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In the prior art, when heating a billet, the heat release from the heating source is diffuse, which easily leads to the loss of most of the heat and reduces the energy utilization rate when heating the billet. In contrast, the heating tube of the present invention is provided with a reflector above it. The bottom of one side of the reflector is connected to the shaft pin frame by a shaft pin. The cylindrical billet is placed above the first conveying roller and the second conveying roller. During the heating process, the reflector reflects the heat, thereby using the arc-shaped reflective surface to reflect most of the heat to the cylindrical billet. This ensures the working efficiency of the heating tube, reduces the heat loss caused by the energy dissipation of the heating tube, improves the heating efficiency of the cylindrical billet, improves the energy utilization rate, and reduces production costs.

[0024] 2. In the existing technology, it is often difficult to observe the heating status of the billet during the heating process. Generally, the equipment is equipped with an observation window, but the observation window can only observe a relatively close area. It is often difficult to observe and operate inside the equipment, making it difficult to control the heating status of the billet. However, the equipment cavity of the present invention is equipped with a first motor. A rotating rod is fixedly connected to the output shaft of the first motor. A connecting rod is connected to the end of the rotating rod away from the output shaft of the first motor through a shaft pin. The rotating rod can drive the connecting rod to pull the reflector, thereby opening the reflector. At this time, the operator can directly observe the heating status of the cylindrical billet being heated. After the observation is completed, the reflector can be closed by controlling the first motor to work in reverse. The operation is simple and fast, and it is convenient for the operator to control the heating status of the cylindrical billet in real time.

[0025] 3. In the prior art, when loading and unloading cylindrical blanks, their cylindrical shape often makes them prone to rolling, leading to difficulties in loading and unloading and affecting overall processing efficiency. However, in this invention, the first gear is connected to the three-ring gear via a first chain belt, and the second gear is connected to the three-ring gear via a second chain belt. During loading and unloading, the three-ring gear can simultaneously drive multiple conveyor rollers to rotate, thereby using the rotation of the spiral pattern to load or unload the cylindrical blank. This fully addresses the shape characteristics of the cylindrical blank, improves the convenience and efficiency of loading and unloading, and increases production efficiency.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-3A heating device for cylindrical billets of wind turbine components includes a body 1 and a cylindrical billet 4. A fan 2 is installed on the top of the body 1, and a heating assembly 3 is installed inside the body 1. The cylindrical billet 4 is installed inside the heating assembly 3. A feed inlet 12 is opened on the front of the body 1. The position and number of feed inlets 12 are matched with the heating assembly 3. A shaft pin bracket 11 is installed on one side of the feed inlet 12. The position and number of shaft pin brackets 11 are matched with the heating assembly 3. A connecting rod 13 is installed above the heating assembly 3. The heating assembly 3 is provided with a first heating position 31, a second heating position 32, a third heating position 33 and a fourth heating position 34. A transmission assembly 5 is installed at the bottom of the body 1. The first heating position 31, the second heating position 32, the third heating position 33 and the fourth heating position 34 are all connected to the transmission assembly 5. The first heating position 31, the second heating position 32, the third heating position 33 and the fourth heating position 34 have the same overall structure, and are connected by a connecting rod 13.

[0037] Specifically, before heating, the inside of the machine body 1 is preheated by the fan 2 and the heating component 3. Then, the cylindrical blank 4 is fed by the first heating position 31, the second heating position 32, the third heating position 33 and the fourth heating position 34 through the transmission component 5. After the first heating position 31, the second heating position 32, the third heating position 33 and the fourth heating position 34 have finished heating the cylindrical blank 4, the transmission component 5 drives it to unload, thus completing the heating work.

[0038] To address the technical problem that during billet heating, the heat release from the heating source is diffuse, leading to significant heat loss and reduced energy utilization during billet heating, please refer to [link to relevant documentation]. Figure 2-4 The present invention provides the following technical solutions:

[0039] The first heating position 31 includes a first conveyor roller 3101, a second conveyor roller 3102, a spiral 3103, a connecting end 3104, a heating tube 3105, a reflector 3106, a moving shaft 3107, a hinge end 3108, and a connecting tube 3109. The first conveyor roller 3101 and the second conveyor roller 3102 are arranged in parallel. Both ends of the first conveyor roller 3101 and the second conveyor roller 3102 are rotatably connected to the machine body 1 through the connecting end 3104. The outer sides of the first conveyor roller 3101 and the second conveyor roller 3102 are... A spiral pattern 3103 is provided. A heating tube 3105 is provided above the first conveyor roller 3101 and the second conveyor roller 3102. One end of the heating tube 3105 is connected to the machine body 1 through a connecting tube 3109. A reflector 3106 is provided above the heating tube 3105. The bottom of one side of the reflector 3106 is connected to the shaft pin frame 11 through a shaft pin. A moving shaft 3107 is provided on the top of the reflector 3106. The two ends of the moving shaft 3107 are set as connecting ends 3104. The connecting ends 3104 are connected to the connecting rod 13 through shaft pins. A cylindrical blank 4 is provided above the first conveyor roller 3101 and the second conveyor roller 3102.

[0040] Specifically, during the heating process, the heating tube 3105 heats the cylindrical blank 4. During the heating process, the reflector 3106 reflects the heat, thereby using the arc-shaped reflective surface to reflect most of the heat onto the cylindrical blank 4. This ensures the working efficiency of the heating tube 3105, reduces heat loss caused by the energy dissipation of the heating tube 3105, improves the heating efficiency of the cylindrical blank 4, increases energy utilization, and reduces production costs.

[0041] To address the challenge of monitoring the heating status of billets during the heating process, most equipment is equipped with observation windows. However, these windows typically only provide a close-up view, making it difficult to observe and operate within the equipment itself. This hinders effective control over the heating status of the billets. Please refer to [link to relevant documentation]. Figure 5-6 The present invention provides the following technical solutions:

[0042] A device cavity 14 is provided on one side of the body 1. A first motor 15 is installed inside the device cavity 14. A rotating rod 16 is fixedly connected to the output shaft of the first motor 15. The end of the rotating rod 16 away from the output shaft of the first motor 15 is slidably installed inside the slide rail 17. A connecting rod 18 is connected to the end of the rotating rod 16 away from the output shaft of the first motor 15 by a shaft pin. A through hole 19 is provided on one side of the device cavity 14. The end of the connecting rod 18 away from the rotating rod 16 passes through the through hole 19 and is connected to the connecting rod 13 by a shaft pin. An electric heating tube 110 is connected to one side of the device cavity 14. The electric heating tube 110 is located below the fan 2.

[0043] Specifically, in actual operation, starting the first motor 15 will drive the rotating rod 16 to make a circular motion via the output shaft. At this time, the other end of the rotating rod 16 will slide in a circular motion along the slide rail 17. Thus, the connecting rod 13 connected to the rotating rod 16 can pull the reflector 3106 at the top of the first heating position 31, the second heating position 32, the third heating position 33 and the fourth heating position 34. The reflector 3106 moves around the shaft pin frame 11 as the center under the pull of the connecting rod 13, thereby opening the reflector 3106. At this time, the operator can directly observe the heating status of the cylindrical blank 4 being heated. After the observation is completed, the reflector 3106 can be closed by controlling the first motor 15 to work in reverse. The operation is simple and fast, and it is convenient for the operator to control the heating status of the cylindrical blank 4 in real time.

[0044] To address the technical problem of cumbersome loading and unloading of cylindrical billets due to their tendency to roll easily, thus affecting overall processing efficiency, please refer to the figure. Figure 4 and Figure 7-8 The present invention provides the following technical solutions:

[0045] The transmission assembly 5 includes a first gear 51, a second gear 52, a three-ring gear 53, a second motor 54, a first chain belt 55, a second chain belt 56, and a main chain belt 57. Four three-ring gears 53 are provided, and they are connected to each other via the main chain belt 57. Each three-ring gear 53 is located below the first heating position 31, the second heating position 32, the third heating position 33, and the fourth heating position 34, respectively. Above each three-ring gear 53, there is a first gear 51 and a second gear. 52. The central shaft of the first gear 51 is fixedly connected to the connecting end 3104 of the first conveyor roller 3101. The first gear 51 is connected to the three-ring gear 53 via the first chain belt 55. The central shaft of the second gear 52 is fixedly connected to the connecting end 3104 of the second conveyor roller 3102. The second gear 52 is connected to the three-ring gear 53 via the second chain belt 56. A second motor 54 is provided behind the three-ring gear 53. The output shaft of the second motor 54 is fixedly connected to the central shaft of the three-ring gear 53.

[0046] The three-ring gear 53 includes a first gear ring 5301, a second gear ring 5302, a third gear ring 5303, and a partition plate 5304. There are two partition plates 5304, which are respectively disposed between the first gear ring 5301, the second gear ring 5302, and the third gear ring 5303. The first chain belt 55 is sleeved on the outside of the first gear ring 5301, the second chain belt 56 is sleeved on the outside of the second gear ring 5302, and the main chain belt 57 is sleeved on the outside of the third gear ring 5303.

[0047] Specifically, during loading and unloading operations, the second motor 54 is started, which drives the first three-ring gear 53 to rotate. Subsequently, all three-ring gears 53 rotate simultaneously under the drive of the main chain belt 57. The three-ring gears 53 drive the first gear 51 and the second gear 52 to rotate through the first chain belt 55 and the second chain belt 56. The first conveyor roller 3101 and the second conveyor roller 3102 rotate. At the same time as the first conveyor roller 3101 and the second conveyor roller 3102 rotate, the spiral pattern 3103 rotates synchronously. This allows the three-ring gears 53 to drive multiple conveyor rollers to rotate simultaneously. The rotation of the spiral pattern 3103 is used to load or unload the cylindrical blank 4, which fully takes into account the shape characteristics of the cylindrical blank 4, improves the convenience and efficiency of loading and unloading, and increases production efficiency.

[0048] To better demonstrate the heating equipment for cylindrical billets of wind turbine components, this embodiment proposes an implementation method for the heating equipment, including the following steps:

[0049] Step 1: Turn on fan 2, heating element 3105 and electric heating element 110 to preheat the inside of the machine body 1;

[0050] Step 2: Start the second motor 54. The second motor 54 drives each three-ring gear 53 to rotate. The three-ring gear 53 drives the first gear 51 and the second gear 52 to rotate through the first chain belt 55 and the second chain belt 56. The first conveyor roller 3101 and the second conveyor roller 3102 rotate. At the same time as the first conveyor roller 3101 and the second conveyor roller 3102 rotate, the spiral 3103 rotates synchronously. The rotation of the spiral 3103 feeds the cylindrical blank 4.

[0051] Step 3: The cylindrical blank 4 is above the first conveying roller 3101 and the second conveying roller 3102. The heating tube 3105 works to heat the cylindrical blank 4. During the heating process, the reflector 3106 reflects the heat to improve the heating efficiency of the cylindrical blank 4.

[0052] Step 4: After heating is completed, start the second motor 54, and drive the spiral 3103 to rotate through the first conveyor roller 3101 and the second conveyor roller 3102 to unload the heated cylindrical blank 4.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The three-ring gear (53) drives the first gear (51) and the second gear (52) to rotate through the first chain belt (55) and the second chain belt (56). The first conveyor roller (3101) and the second conveyor roller (3102) rotate. At the same time as the first conveyor roller (3101) and the second conveyor roller (3102) rotate, the spiral pattern (3103) rotates synchronously. The spiral pattern (3103) rotates to feed the cylindrical blank (4). Step 3: The cylindrical blank (4) is above the first conveyor roller (3101) and the second conveyor roller (3102). The heating tube (3105) works to heat the cylindrical blank (4). During the heating process, the reflector (3106) reflects the heat to improve the heating efficiency of the cylindrical blank (4). Step 4: After heating is completed, start the second motor (54), and drive the spiral (3103) to rotate through the first conveyor roller (3101) and the second conveyor roller (3102) to unload the heated cylindrical blank (4).
