[0002] Cutting the raw materials for the production of thick plate door frames for wind turbine towers is a critical process. This process usually involves the use of specialized cutting equipment and techniques, such as plasma arc cutting or torch cutting. These techniques ensure that the thick plate material is cut into the required shape and size accurately and efficiently. During the cutting process, it is necessary to ensure that the cut surface is smooth, free of burrs and cracks, in order to meet the requirements of subsequent processing and assembly.
[0003] In the existing technology, thick plate door frames for wind turbine towers are usually made by welding two curved metal plates. The welding parts of the metal plates usually need to be beveled to facilitate subsequent cutting and ensure welding quality. However, since the metal plates of thick plate door frames for wind turbine towers occupy a large space, it is inconvenient for operators to keep the flame cutting gun stable. Therefore, a raw material cutting device for the production of thick plate door frames for wind turbine towers is proposed to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-5 As shown, a raw material cutting device for producing thick plate door frames of wind turbine towers includes a support mechanism 1, with a cutting mechanism 2 disposed on one side of the support mechanism 1. The cutting mechanism 2 includes a lifting rail 201, with an upper toothed disc 210 fixedly connected to the bottom of the lifting rail 201. A lifting block 203 is slidably connected to the inner side of the lifting rail 201, with one end of the lifting block 203 extending to the outside of the lifting rail 201. A rotating block 205 is movably mounted on the end of the lifting block 203 located outside the lifting rail 201. A fixed hoop 206 is fixedly connected to the side of the rotating block 205 away from the lifting block 203, and a movable hoop 207 is slidably connected to the outer wall of the rotating block 205 near the fixed hoop 206. Both the fixed hoop 206 and the movable hoop 207 have through holes at their outer wall ends. Figure 2 As shown, when the fixed hoop 206 and the movable hoop 207 clamp and fix the flame cutting gun together, the flame cutting gun can only move along the height direction of the lifting rail 201, thereby avoiding cutting deviation.
[0027] A rotating shaft 208 is fixedly connected to the center of the side of the rotating block 205 near the lifting block 203. The outer wall of the rotating shaft 208 is rotatably connected to the inner wall of the lifting block 203, and a washer 209 is also fixedly connected to the outer wall of the rotating shaft 208. Figure 5 As shown, washer 209 is made of rubber;
[0028] A bolt 204 is threaded onto one side of the outer wall of the lifting block 203. The end of the bolt 204 penetrates into the lifting block 203 and abuts against the washer 209. A vertical groove 202 is also provided on the side wall of the lifting rail 201 near the bolt 204. The vertical groove 202 is consistent with the lifting rail 201 in the length direction. Figure 2 As shown, bolt 204 can be tightened through the vertical groove 202;
[0029] The support mechanism 1 includes a cutting platform 101. A processing opening 102 is provided on one side of the cutting platform 101. A base plate 107 is fixedly connected to the inner side of the processing opening 102. The top of the base plate 107 is rotatably connected to a lifting rail 201, and the interior of the base plate 107 is movably installed with an upper gear 210. The top of the lifting rail 201 extends above the cutting platform 101. A spring 108 is fixedly connected to the bottom of the inner wall of the base plate 107. A lower gear 109 is fixedly connected to the top of the spring 108. The top of the lower gear 109 meshes with the upper gear 210. A push rod 110 is fixedly connected to the side of the lower gear 109. The outer wall of the push rod 110 is slidably connected to the inner wall of the base plate 107, and the top of the push rod 110 protrudes from the upper surface of the base plate 107. Figures 3-4 As shown, the spring 108 pushes the lower sprocket 109 upward to engage with the upper sprocket 210, thereby fixing the upper lifting rail 201 relative to the lower sprocket 109, and the push rod 110 prevents the lower sprocket 109 from rotating within the base plate 107.
[0030] A stop block 103 is fixedly connected to the center of the top surface of the cutting platform 101. Fixed clamping plates 104 are fixedly connected to both sides of the top surface of the cutting platform 101. Movable clamping plates 105 are symmetrically slidably connected to the top surface of the cutting platform 101 and inside the two fixed clamping plates 104. Bolts 106 are threaded through and threaded onto the inner walls of both the fixed clamping plates 104 and the movable clamping plates 105. Figure 1 As shown, the abutment block 103 and the fixed clamping plate 104 limit the steel plate to be cut, and the movable clamping plate 105 holds the steel plate in place to keep the steel plate stable during cutting.
[0031] The working principle of this utility model:
[0032] like Figure 1As shown, the steel plate to be cut is placed above the cutting platform 101. The two sides of the steel plate are clamped by the fixed clamping plates 104 and the movable clamping plates 105 on both sides. The fixed clamping plates 104 and the movable clamping plates 105 are kept relatively fixed by bolts 106, thereby ensuring stable clamping.
[0033] Place the flame cutting torch head inside the fixed clamp 206, with the movable clamp 207 abutting against the fixed clamp 206. Secure the fixed clamp 206 and movable clamp 207 with bolts and nuts to ensure stable clamping of the flame cutting torch. Loosen bolt 204 to separate its end from the rotating shaft 208. The rotating block 205 can rotate relative to the lifting block 203, adjusting the cutting angle of the flame cutting torch on the steel plate. Next, move the push rod 110 downward, causing the lower toothed plate 109 to separate from the upper toothed plate 210. At this time, the lifting rail 201 can rotate, thereby adjusting the bevel angle of the flame cutting torch on the steel plate. After releasing the push rod 110, the spring 108 pushes the lower toothed plate 109 upward and re-engages it with the upper toothed plate 210, fixing the lifting rail 201.
[0034] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
