Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine tower processing, and in particular to an internal wall rust removal device for wind turbine tower production and processing. Background Technology

[0002] As a key supporting structure for wind turbine generators, the quality of the inner wall of the wind turbine tower directly affects the safety and service life of the equipment. In production, processing, and subsequent operation and maintenance, rust removal of the inner wall is a core process for ensuring the tower's corrosion resistance. Oxidation of the steel surface during production, welding spatter residue, and corrosion from humid environments during storage and transportation easily lead to the formation of contaminants such as scale, rust, and oil stains.

[0003] As a large and critical component of wind power equipment, the tower section can be tens of meters long and typically weighs tons. During the production and processing, it requires large hoisting equipment for transportation, stacking, and subsequent assembly. If the equipment cannot be quickly separated from the tower after rust removal, a series of hoisting challenges arise. When the equipment is fixed inside the tower, the internal space is occupied, making it difficult for the lifting equipment to pass through and properly secure the tower during hoisting. Forced hoisting may cause the tower to tilt, collide, or even deform or damage its surface due to misalignment of the stress points. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an internal rust removal device for the production and processing of wind turbine towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rust removal device for the inner wall of wind turbine towers during production and processing includes a frame. Plates are fitted to one and the other ends of the frame. Multiple sets of bolts are threaded to one end of each set of plates, and these bolts are threaded to the frame. Two sets of studs are connected to one end of each set of plates. A set of connecting members is movably passed through each pair of studs. Rods are rotatably connected to each pair of connecting members. A set of grinding rollers is fitted to each pair of rods. Two sets of nuts are threaded to each set of studs, and these nuts are respectively fitted to corresponding connecting members. Mounting seats are fitted to each set of mounting seats, and wheels are rotatably connected to each mounting seat.

[0006] Preferably, the frame has multiple sets of sliding grooves, and the frame is rotatably connected to two sets of double-ended threaded rods. A second motor is installed at one end of the frame, and the second motor is connected to a set of double-ended threaded rods through a coupling. Each of the multiple sets of mounting seats has a slider connected to one end, and the multiple sets of sliders are slidably connected to the corresponding sliding grooves and threadedly connected to the corresponding double-ended threaded rods.

[0007] Preferably, each of the mounting bases is equipped with a motor, and the two sets of motors are respectively connected to the corresponding wheel body through couplings, and a knob is connected to one end of each of the multiple sets of bolts.

[0008] Preferably, both sets of double-ended threaded rods are connected to synchronous pulleys, and the two sets of synchronous pulleys are connected by synchronous belt drive.

[0009] Preferably, a motor is installed at one end of one set of the connecting parts, and the motor is connected to a set of rods through a coupling. Multiple sets of reinforcing ribs are connected to one end and the other end of the frame.

[0010] Preferably, each of the two sets of rods has a groove at one end, and each of the grinding rollers has a block connected to one end and the other end, with the two sets of grooves respectively inserted into and engaged with the block.

[0011] Preferably, both sets of blocks are hexagonal and fit into the groove.

[0012] The beneficial effects of this utility model are as follows: 1. By cooperating with the stud, connector, and rod, the nut is turned to remove the restriction on the connector, allowing the connector to move up and down along the stud. The position of the grinding roller can then be adjusted according to the tower size and thickness to fit against the inner wall of the tower. Motor 1 is started to drive the wheel to rotate, and the friction between the wheel and the outer wall of the tower drives the tower to rotate. At the same time, motor 3 is started to drive the rod to rotate, and the rod drives the grinding roller to rotate through the cooperation of the groove and the block, grinding the inner wall of the tower. After grinding, the bolt can be unscrewed to remove the connection between the plate and the frame, and the plate can be removed. Then the block can be moved out of the groove, the clamping of the grinding roller can be removed, and the grinding roller can be moved out, making it convenient to move the tower. It has a wide range of applications to a certain extent. 2. Through the cooperation between the set motor two, the double-headed threaded rod and the slider, the start motor two drives the two sets of double-headed threaded rods to rotate together through the cooperation of the synchronous pulley and the synchronous belt. The rotation of the double-headed threaded rod drives multiple sets of mounting seats to move in opposite directions or away from each other, thereby adjusting the distance between the mounting seats. To a certain extent, it can adapt to wind turbine towers of different sizes. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1, referring to Figures 1 to 5 A rust removal device for the inner wall of wind turbine towers during production and processing includes a frame 1. Plates 2 are fitted onto one and the other ends of the frame 1. Multiple sets of bolts 3 are threadedly connected to one end of each set of plates 2, used to fix the plates 2 to one end of the frame 1. Two sets of studs 4 are connected to one end of each set of plates 2. A connecting piece 5 moves along the studs 4 to adjust the position of a grinding roller 7, allowing it to fit against the inner wall of towers of different sizes. After adjustment, a nut 8 is tightened to fit against the connecting piece 5, fixing it in place. Each pair of studs 4 movably passes through the same connecting piece 5. Both sets of connecting pieces 5 are rotatably connected to rods 6, with both sets of rods 6 fitting together. A set of grinding rollers 7 are placed together. The grinding rollers 7 rotate to grind the tower. They can only grind the tower within the length range of the grinding rollers 7. Multiple sets of studs 4 are threaded together with two sets of nuts 8. The multiple sets of nuts 8 are respectively attached to the corresponding connecting parts 5. Mounting seats 9 are attached to the frame 1. Multiple sets of mounting seats 9 are rotatably connected to wheels 10. Some wheels 10 are active, and the rest are driven. The driven wheels play an auxiliary support role. The active wheels can drive the tower to rotate. Unscrew the bolts 3 to remove the restriction on the plate 2. Move the plate 2 to remove the restriction on the grinding rollers 7. Move the grinding rollers 7 out of the tower. This facilitates the hoisting of the tower to a certain extent and has a wide range of applications.

[0017] In this embodiment, the frame 1 has multiple sets of sliding grooves 12, which guide the movement of the slider 21. The frame 1 is rotatably connected to two sets of double-ended threaded rods 13. The rotation of the double-ended threaded rods 13 drives the mounting base 9 to move through the slider 21. A second motor 16 is installed at one end of the frame 1. The model of the second motor 16 can be selected according to the actual situation. The second motor 16 is connected to a set of double-ended threaded rods 13 through a coupling. The second motor 16 drives the double-ended threaded rods 13 to rotate. Each of the multiple mounting bases 9 has a slider 21 connected to one end. The multiple sliders 21 are slidably connected to the corresponding sliding grooves 12 and threadedly connected to the corresponding double-ended threaded rods 13. By rotating the double-ended threaded rods 13, the mounting base 9 is moved, thereby adjusting the position of the wheel 10. To a certain extent, it can adapt to towers of different sizes. Each mounting base 9 is equipped with a motor 11. The model of motor 11 can be selected according to the actual situation. Two sets of motors 11 are connected to the corresponding wheel 10 through couplings. Motors 11 drive the wheel 10 to rotate. The friction between the rotating wheel 10 and the tower cylinder drives the tower cylinder to rotate. One end of each set of bolts 3 is connected to a knob 18, which makes it easier to tighten the bolts 3. Both sets of double-ended threaded rods 13 are connected to synchronous pulleys 14. The two sets of synchronous pulleys 14 are connected by a synchronous belt 15. Through the cooperation of the synchronous pulleys 14 and the synchronous belt 15, the two sets of double-ended threaded rods 13 rotate together. One end of a connecting piece 5 is equipped with a motor 3 17. The model of motor 3 17 can be selected according to the actual situation. Motor 3 17 is connected to a set of rods 6 through a coupling. Motor 3 17 drives the rods 6 to rotate. One end of the frame 1 is connected to multiple sets of reinforcing ribs, which strengthen the structural strength to a certain extent. Both sets of rods 6 have grooves 19 at one end, and blocks 20 are connected to one and the other ends of the grinding roller 7. The grooves 19 are inserted into the blocks 20, providing positioning for the installation of the grinding roller 7 and supporting it. Both blocks 20 are hexagonal and fit into the grooves 19. The hexagonal design allows the rods 6 to rotate the blocks 20 through the grooves 19, and the blocks 20 in turn rotate the grinding roller 7 to grind the inner wall of the tower.

[0018] The working principle of this embodiment is as follows: During use, rotating the nut 8 releases the restriction on the connector 5, allowing it to move up and down along the stud 4. Adjusting the height of the grinding roller 7 according to the actual dimensions and inner wall thickness of the wind turbine tower ensures a tight fit between the grinding roller 7 and the inner wall of the tower. Starting the second motor 16, which drives a set of double-threaded rods 13 via a coupling, the two sets of double-threaded rods 13 rotate synchronously through the transmission of the synchronous pulley 14 and synchronous belt 15. As the double-threaded rods 13 rotate, they drive the threadedly connected slider 21 to slide along the slide groove 12, thereby causing multiple sets of mounting seats 9 to move towards or away from each other, adjusting the spacing between the mounting seats 9 to accommodate wind turbine towers of different diameters. Starting the first motor 11 installed on some of the mounting seats 9, which drives the wheel 10 to rotate via a coupling, the friction between the wheel 10 and the outer wall of the tower drives the entire tower to rotate. Start the motor 3 17 installed on a set of connecting parts 5. The motor 3 17 drives the rod 6 to rotate through the coupling. Since the hexagonal blocks 20 at both ends of the grinding roller 7 are inserted and engaged with the grooves 19 at the ends of the rod 6, the rotation of the rod 6 can drive the grinding roller 7 to rotate synchronously. The rotating grinding roller 7 performs grinding and rust removal operations on the inner wall of the rotating tower. After the rust removal operation is completed, unscrew the bolt 3 by turning the knob 18 at the end of the bolt 3 to disconnect the plate 2 from the frame 1. Remove the plate 2 and remove the blocks 20 of the grinding roller 7 from the grooves 19 of the rod 6 to separate the equipment from the tower, which facilitates the subsequent hoisting operation of the tower.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
