Technical Field
[0001] This utility model belongs to the field of wind turbine tower blade processing technology, and specifically relates to a wind turbine tower blade bending device. Background Technology
[0002] With the global energy structure shifting towards cleaner and renewable energy, wind power, as a mature and efficient clean energy utilization method, has seen its industry scale expand rapidly. The wind turbine tower, as the core supporting component of a wind turbine generator, plays a crucial role in fixing the unit and ensuring stable equipment operation. The tower segments are the basic units that make up the wind turbine tower. Typically, wind turbine tower segments are made from steel plates, which undergo multiple processing steps such as cutting and bending to shape the flat steel plates into arc-shaped structures with specific curvatures. These arc-shaped tower segments are then assembled into a complete wind turbine tower through subsequent splicing and welding processes.
[0003] After the steel plate is formed into a curved tower sheet according to the requirements by the extrusion and bending rollers, the bent tower sheet needs to be removed from the device. Because the tower sheet has its own weight, it will fall naturally under gravity and adhere to the surface of the extrusion and bending rollers below after losing the support of the bending rollers. At this time, a large contact area is formed between the tower sheet and the extrusion and bending rollers. During the axial extraction of the tower sheet, significant sliding friction resistance is generated between the two. This large friction resistance not only requires the operator to apply greater external force, but also increases the labor intensity. Utility Model Content
[0004] To address the issue that after losing the support of the bending roller assembly, the material will naturally fall under gravity and adhere to the surface of the pressing bending roller below, generating significant sliding friction resistance. This large friction resistance not only requires operators to apply greater external force, increasing labor intensity, but also presents a wind turbine tower blade bending device to overcome the aforementioned technical problems in existing related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a wind turbine tower blade bending device, comprising a body, a rotating roller rotatably connected to the outer surface of the body, an extrusion assembly and a guide assembly disposed on the outer surface of the body, the guide assembly being located on the side of the extrusion assembly, the extrusion assembly being located at the bottom of the rotating roller, a pre-bending assembly and a support assembly disposed on the side of the body, the support assembly being used to support the rotating roller.
[0006] Furthermore, the extrusion assembly includes an extrusion push rod, which is fixedly installed on the top of the machine body. A support is fixedly installed on the movable end of the extrusion push rod, and an extrusion roller is rotatably connected to the outer surface of the support. There are two sets of extrusion rollers, which are located on both sides of the rotating roller.
[0007] Furthermore, the guide assembly includes an adjusting push rod, which is fixedly connected to the top of the machine body. The movable end of the adjusting push rod is fixedly connected to a guide frame. The guide frame is rotatably connected to a pin, and the outer surface of the pin is fixedly connected to a guide wheel. There are multiple sets of pins and guide wheels.
[0008] Furthermore, the pre-bending assembly includes a fixed base, which is fixedly connected to the side of the machine body. A bracket is fixedly installed inside the fixed base, and a pre-bending top roller is rotatably connected to the outer surface of the bracket.
[0009] Furthermore, the support assembly includes a side plate, which is fixedly connected to the side of the machine body. A groove is formed on the outer surface of the side plate, and a sliding rod is slidably connected inside the groove. A support base is fixedly connected to the outer surface of the sliding rod. An ear plate is fixedly connected to the outer surface of the side plate, and a fixing bolt is threadedly connected to the outer surface of the ear plate. The fixing bolt passes through the ear plate and is threadedly connected to the support base.
[0010] Furthermore, there are two sets of pre-bending top rollers, and the two sets of pre-bending top rollers have different heights.
[0011] Furthermore, the adjusting push rod, guide frame, pin shaft, and guide wheel all have an inclination angle.
[0012] This utility model has the following beneficial effects: This invention connects the extrusion assembly and the guide assembly. The two sets of guide assemblies are located on both sides of the extrusion assembly. After the guide assembly is started, it supports the tower plate formed between the extrusion assembly and the rotating roller from both sides. Then the extrusion assembly descends and the tower plate is removed. The tower plate drives the guide assembly to rotate. The rotation of the guide assembly reduces the frictional resistance when the tower plate is unloaded, which facilitates unloading and reduces labor intensity.
[0013] This invention connects the support base and the sliding rod. After the limit and fixation of the support base are released, the support base is pulled to drive the sliding rod to slide along the slide groove, so that the support base is separated from the rotating roller. Then the support base is rotated downward. At this time, the support base is no longer located in the unloading path of the tower plate, and the tower plate can be taken out from above the support base.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0020] Please see Figures 1-6 As shown, this utility model is a wind turbine tower blade bending device, including a body 1. A rotating roller 2 is rotatably connected to the outer surface of the body 1. An extrusion assembly 3 and a guide assembly 4 are provided on the outer surface of the body 1. The guide assembly 4 is located on the side of the extrusion assembly 3. The extrusion assembly 3 is located at the bottom of the rotating roller 2. A pre-bending assembly 5 and a support assembly 6 are respectively provided on the side of the body 1. The support assembly 6 is used to support the rotating roller 2.
[0021] The flat tower plate is inserted from one side of the machine body 1 between the rotating roller 2 and the extrusion assembly 3. After the rotating roller 2 is started, the friction between the rotating roller 2 and the extrusion assembly 3 drives the tower plate to move to the other side of the machine body 1. The pre-bending assembly 5 on the other side of the machine body 1 lifts the tower plate, giving it a certain initial curvature. Then, the extrusion assembly 3 gradually moves upward to push the tower plate to bend until it forms a cylinder. The guide assembly 4 is started to move it obliquely upward to support the tower plate. Then, the support assembly 6 on the side of the machine body 1 is released from the rotating roller 2. At the same time, the extrusion assembly 3 descends. At this time, the formed tower plate can be taken out from the side of the rotating roller 2. During the removal process, the tower plate reduces friction through the rotation of the guide assembly 4, which facilitates unloading.
[0022] This invention connects the extrusion assembly 3 and the guide assembly 4. The two sets of guide assemblies 4 are located on both sides of the extrusion assembly 3. After the guide assembly 4 is started, it supports the tower plate formed between the extrusion assembly 3 and the rotating roller 2 from both sides. Then the extrusion assembly 3 descends and the tower plate is taken out. The tower plate drives the guide assembly 4 to rotate. The rotation of the guide assembly 4 reduces the frictional resistance when the tower plate is unloaded, which facilitates unloading and reduces labor intensity.
[0023] In one embodiment, the extrusion assembly 3 includes an extrusion push rod 301, which is fixedly installed on the top of the machine body 1. A support 302 is fixedly installed on the movable end of the extrusion push rod 301. An extrusion roller 303 is rotatably connected to the outer surface of the support 302. There are two sets of extrusion rollers 303, which are located on both sides of the rotating roller 2.
[0024] After the tower plate passes between the extrusion roller 303 and the rotating roller 2, the extrusion push rod 301 is activated. The extrusion push rod 301 pushes the support 302 to drive the extrusion roller 303 to move upward. The extrusion roller 303 and the rotating roller 2 cooperate to bend the tower plate, so that the tower plate has a certain curvature. When the machine body 1 drives the rotating roller 2 to rotate, the friction between the rotating roller 2, the tower plate and the extrusion roller 303 can drive the tower plate to rotate, so that the tower plate is bent into a cylindrical shape.
[0025] In one embodiment, the guide assembly 4 includes an adjusting push rod 401, which is fixedly connected to the top of the body 1. The movable end of the adjusting push rod 401 is fixedly connected to a guide frame 402. A pin 403 is rotatably connected inside the guide frame 402. A guide wheel 404 is fixedly connected to the outer surface of the pin 403. There are multiple sets of pins 403 and guide wheels 404.
[0026] After bending is completed, the adjusting push rod 401 is activated. The movable end of the adjusting push rod 401 pushes the guide frame 402 to move. The guide frame 402 drives the guide wheel 404 to approach and abut against the formed tower plate. Then, the extrusion push rod 301 drives the extrusion roller 303 to descend and move away from the tower plate. At this time, the tower plate is supported by the guide wheel 404. The adjusting push rod 401 drives the guide wheel 404 to descend, so that the tower plate separates from the rotating roller 2. When the tower plate is taken out from the side of the rotating roller 2, the tower plate drives the guide wheel 404 to rotate. The rotation of the guide wheel 404 and the pin 403 reduces the frictional resistance encountered by the tower plate when it moves, making it easier to unload and reducing labor intensity.
[0027] In one embodiment, the pre-bending assembly 5 includes a fixed seat 501, which is fixedly connected to the side of the machine body 1. A bracket 502 is fixedly installed inside the fixed seat 501, and a pre-bending top roller 503 is rotatably connected to the outer surface of the bracket 502.
[0028] When the tower plate is first passed between the rotating roller 2 and the extrusion roller 303 from one side of the machine body 1 for bending, the tower plate that comes out from the other side of the machine body 1 comes into contact with the pre-bending top roller 503, and the pre-bending top roller 503 plays a guiding role in bending the tower plate.
[0029] In one embodiment, the support assembly 6 includes a side plate 601, which is fixedly connected to the side of the body 1. The outer surface of the side plate 601 is provided with a sliding groove 602, and a sliding rod 603 is slidably connected inside the sliding groove 602. A support base 604 is fixedly connected to the outer surface of the sliding rod 603. An ear plate 605 is fixedly connected to the outer surface of the side plate 601, and a fixing bolt 606 is threadedly connected to the outer surface of the ear plate 605. The fixing bolt 606 passes through the ear plate 605 and is threadedly connected to the support base 604.
[0030] After bending, remove the fixing bolt 606 to release the connection between the fixing bolt 606 and the support base 604 and the ear plate 605. Pull the support base 604 to slide along the slide groove 602 via the sliding rod 603. The support base 604 moves away from the rotating roller 2. At the same time, rotate the support base 604 downward. At this time, the support base 604 no longer blocks the tower plate between the rotating roller 2 and the extrusion roller 303. The tower plate can be removed from between the rotating roller 2 and the extrusion roller 303.
[0031] In one embodiment, there are two sets of the pre-bending top roller 503, and the two sets of pre-bending top rollers 503 have different heights.
[0032] The bracket 502 and the fixed base 501 are detachably fixedly connected, which makes it easy to adjust the position of the bracket 502 so that the pre-bent top roller 503 of different heights can contact the tower plate.
[0033] In one embodiment, the adjusting push rod 401, the guide frame 402, the pin 403, and the guide wheel 404 all have a certain tilt angle.
[0034] The guide wheel 404 with a certain tilt angle has a large contact area when it abuts against the tower plate, thus avoiding insufficient support.
[0035] Through the above technical solution, 1. By connecting the extrusion assembly 3 and the guide assembly 4, the two sets of guide assemblies 4 are located on both sides of the extrusion assembly 3. After the guide assembly 4 is started, the guide assembly 4 supports the tower plate formed between the extrusion assembly 3 and the rotating roller 2 from both sides. Then the extrusion assembly 3 descends. When the tower plate is taken out, the tower plate drives the guide assembly 4 to rotate. The rotation of the guide assembly 4 reduces the frictional resistance when the tower plate is unloaded, which facilitates unloading and reduces labor intensity. 2. By connecting the support seat 604 and the sliding rod 603, after the limit fixation of the support seat 604 is released, the support seat 604 is pulled to drive the sliding rod 603 to slide along the slide groove 602, so that the support seat 604 is separated from the rotating roller 2. Then the support seat 604 is rotated downward. At this time, the support seat 604 is no longer located in the unloading path of the tower plate, and the tower plate can be taken out from above the support seat 604.
