Description

Technical Field

[0001] This application relates to the field of wind turbine tower production technology, specifically to a wind turbine tower pre-sloping device before rolling. Background Technology

[0002] Wind turbine towers are a crucial component of wind turbine generators, primarily supporting the turbine and elevating it to the required height to capture more stable and powerful wind energy. Wind turbine towers are relatively large, with base sections ranging from 20-35 meters in length and 4.5-6.5 meters in diameter. They are constructed from rolled steel plates. Before rolling, the ends of the steel plates need to be beveled before welding them together. Due to the tower's enormous size, automated beveling is difficult, typically requiring manual beveling by workers. Currently, manual beveling requires pre-marking for positioning and then cutting away excess steel plate material, a process that is challenging due to difficulty in alignment and poor chip smoothness at the bevel. Utility Model Content

[0003] In view of the above problems, this application provides a beveling device for wind turbine towers before rolling, which can reduce the difficulty of beveling the ends of steel plates, eliminate the need for pre-marking, and produce a smooth and flat bevel.

[0004] According to one aspect of the embodiments of this application, a pre-slope opening device for wind turbine tower winding is provided. The pre-slope opening device for wind turbine tower winding includes a positioning frame with an L-shaped cross-section. The positioning frame includes two mutually perpendicular bent plates. A roller assembly is rotatably disposed below one of the bent plates. An L-shaped mounting groove is formed in the middle of the positioning frame. A chamfer is provided on one side of the positioning frame between the two bent plates on one side of the mounting groove. A cylindrical end mill is inclinedly disposed within the mounting groove. The inclination angle of the end mill is parallel to the inclination angle of the chamfer. The upper and lower ends of the end mill are rotatably connected to a first fixing component and a second fixing component, respectively. The first fixing component and the second fixing component are respectively fixedly mounted on the two bent plates of the positioning frame. A water spray assembly is disposed at the top of the positioning frame on one side of the mounting groove. The water spray assembly includes a spray head facing the end mill. Handles are respectively disposed on the two bent ends of the positioning frame.

[0005] In some embodiments, a plurality of L-shaped bends are connected between the first fixing component and the second fixing component, and the plurality of bends together form a protective cover over the end mill.

[0006] In some embodiments, a shovel plate is provided on one side of the mounting groove, the shovel plate being inclined and matching the inclination angle of the chamfer, and the shovel plate having a slope.

[0007] In some embodiments, the second fixing component extends into the mounting groove via a ramp-shaped guide plate located below the lowest end of the shovel plate. A collection hopper is provided in the mounting groove below the guide plate, and a filter assembly is detachably connected below the collection hopper.

[0008] In some embodiments, a vertical hole is provided on one of the curved plates of the positioning frame, the roller assembly includes a support frame and a roller rotatably disposed above the support frame, one side of the support frame is slidably connected to the vertical hole via a slide rail, and a tension spring is connected between the slide rail and the inner wall of the vertical hole.

[0009] In some embodiments, the water spray assembly includes an integrated base, and there are multiple spray heads fixed on the integrated base, with each spray head connected to a water supply pipe.

[0010] The beneficial effects of this application are as follows: In this application, the installation of each component is completed by setting a positioning frame. The positioning frame includes two mutually perpendicular curved plates, and one section of the positioning frame is chamfered. Therefore, this device can abut against the top and end of the steel plate to be beveled, using the steel plate itself for limiting its movement. This ensures that the travel direction and path of the device will be along a straight line at the beveled end of the steel plate. During the movement of this device, the end mill completes the chip removal from the end face of the steel plate. The entire beveling process is easy to operate, does not require pre-marking and positioning by the operator, and produces a good bevel effect—smooth, uniform, and continuous. Furthermore, this application also includes a roller assembly located below the steel plate to be beveled. This avoids bevel deformation caused by large-angle tilting of the device due to operator error. Additionally, this application is equipped with a water spray assembly to cool the end mill, ensuring its continuous working capability.

Figure 5This is a schematic diagram of the overall semi-sectional structure of the equipment provided in this application embodiment. The wind turbine tower pre-coiling slope-opening device 100 includes a positioning frame 110 with an L-shaped cross-section. The positioning frame 110 includes two mutually perpendicular bent plates 111. The two bent plates 111 can be integrally formed or formed by welding. A roller assembly 122 is rotatably disposed below one of the bent plates 111. The roller assembly 122 is used to abut against the bottom of the steel plate 200 to be sloped, so as to keep the device stable. An L-shaped mounting groove 112 is opened in the middle of the positioning frame 110. The mounting groove 112 passes through the two bent plates 111 and the connecting end between the two bent plates 111. A chamfer 113 is provided on the positioning frame 110 on one side of the mounting groove 112 between the two bent plates 111. The inclination angle of the chamfer 113 is consistent with the angle of the slope surface of the steel plate after slope opening, so that the chamfer 113 can fit against the slope surface of the steel plate, and further rely on the steel plate to position the device. It should be noted that the chamfer 113 is only formed on one part of the positioning frame 110, with the end mill 130 as the dividing surface. The other part of the positioning frame 110 does not have the chamfer 113. This is because the steel plate at the front end of the end mill 130 has not yet been beveled, and the end of the steel plate is square. At this time, the positioning frame 110 can directly fit against the steel plate. A cylindrical end mill 130 is inclinedly set in the mounting groove 112. The inclination angle of the end mill 130 is parallel to the inclination angle of the chamfer 113, and the angle of the end mill 130 is consistent with the angle of the steel plate bevel. The inclination angle of the end mill 130 is fixed. The upper and lower ends of the end mill 130 are rotatably connected to the first fixing component 131 and the second fixing component 132, respectively. The first fixing component 131 and the second fixing component 132 are respectively fixedly installed on the two curved plates 111 of the positioning frame 110, further ensuring the stability of the end mill 130 during operation. A water spray assembly 140 is provided on the top of the positioning frame 110 on one side of the mounting groove 112. The water spray assembly 140 includes a spray head 141, which faces the end mill 130 and can spray water onto the end mill 130 to cool it down. Handle components 150 are provided on the two bent ends of the positioning frame 110, which are used for operators to hold.

[0016] As can be seen from the above, in this embodiment of the application, during the working process, the operator inserts the handle component 150 into the device from the starting end of the steel plate 200 to be sloped, so that the horizontal section of the curved plate 111 of the positioning frame 110 abuts against the top side of the steel plate 200 to be sloped, the roller assembly 122 abuts against the bottom side of the steel plate 200 to be sloped, and the vertical curved plate 111 abuts against the end of the steel plate 200 to be sloped. Here, the operator needs to press the upper handle component 150 firmly and push the lower handle component 150 horizontally at the same time, so that the device is in close contact with the end of the steel plate 200 to be sloped, and then the vertical opening is started. The end mill 130 moves along the axial direction of the steel plate. The end mill 130 cuts chips at the end of the steel plate to form a nick. As the equipment moves, a section of positioning frame 110 with a chamfer 113 moves and contacts and abuts against the bevel of the steel plate. At this time, the end of the steel plate 200 to be beveled, whether it is the unbeveled area or the beveled area, is in close contact with the positioning frame 110. The top and bottom of the steel plate abut against the lower side of the positioning frame 110 and the roller 122 assembly 120, respectively. The movement of the equipment is limited by the steel plate, so the equipment can move smoothly along the axial direction of the steel plate to complete the beveling operation.

[0017] In summary, in this embodiment, the installation of each component is completed by setting a positioning frame 110. The positioning frame 110 includes two mutually perpendicular curved plates 111, and a chamfer 113 is also provided on one section of the positioning frame 110. Therefore, the device can abut against the top and end of the steel plate 200 to be sloped, using the steel plate 200 itself for limiting, so that the travel direction and path of the device will be in a straight line at the sloped end of the steel plate. During the movement of the device, the end mill 130 completes the chip removal on the end face of the steel plate. The entire sloped process is easy to operate, does not require the operator to mark the positioning line in advance, and has a good sloped effect, with a smooth, uniform and continuous bevel. On the other hand, this application also provides a roller assembly 122 120, which is located below the steel plate 200 to be beveled. This can avoid the deformation of the bevel caused by the large angle tilt of the equipment due to operator error. In addition, this application is also equipped with a water spray assembly 140 to spray water to cool the end mill 130 and ensure its continuous working ability.

[0018] In some embodiments, a plurality of L-shaped bends are connected between the first fixing component and the second fixing component, and the plurality of bends together form a protective cover 160 covering the end mill 130. In this application, the bends can be levers. By setting the bends to form the protective cover 160, the operator is prevented from accidentally putting their hand into the end mill 130 and causing injury.

[0019] In some embodiments, a shovel plate 170 is provided on one side of the mounting groove 112. The shovel plate 170 is inclined and matches the inclination angle of the chamfer 113, and the shovel plate 170 has a slope. In this embodiment, by providing the shovel plate 170, the insert plate is in close contact with the bevel of the steel plate, and the iron filings generated during the cutting process of the end mill 130 can be shoveled upwards, avoiding subsequent iron filings being stuck between the steel plate and the chamfer 113 of the device, causing problems such as inaccurate positioning.

[0020] In some embodiments, the second fixing component 132 extends into the mounting groove 112 via a ramp-shaped guide plate 132a. The guide plate 132a is located below the lowest end of the shovel plate 170. A collection hopper 180 is disposed in the mounting groove 112 below the guide plate 132a, and a filter assembly 181 is detachably connected to the lower part of the collection hopper 180. In this embodiment, with the above arrangement, some of the chips generated during the cutting process of the end mill 130 will be scooped up by the insert plate and fall into the collection hopper 180 under the flushing of the water sprayed by the water spraying component 140. The filter assembly 181 can filter out the water and collect the iron filings.

[0021] In some embodiments, a vertical hole 111a is provided on one of the curved plates 111 of the positioning frame 110. The roller 122 assembly 120 includes a support frame 121 and a roller 122 rotatably disposed above the support frame 121. One side of the support frame 121 is slidably connected to the vertical hole 111a via a slide rail 123. A tension spring 124 is connected between the slide rail 123 and the inner wall of the vertical hole 111a. In this embodiment, by providing the tension spring 124, the support frame 121 is pulled upward. After the support frame 121 moves upward, it drives the roller 122 to press tightly against the bottom of the steel plate 200 to be sloped, further improving the positioning accuracy and stability of the device during operation.

[0022] In some embodiments, the water spray assembly 140 includes an integrated base 142, and multiple spray heads 141 are fixed to the integrated base 142. Each spray head 141 is connected to a water supply pipe 143. In this embodiment, the water supply pipe 143 can be connected to an external water pump and water source. Water is sent into the spray head 141 through the water supply pipe 143 and can be continuously sprayed out by the spray head 141 to the end mill 130 for cooling.
