Description

Technical Field

[0001] The utility model relates to the technical field of wind power tower processing, in particular to a rust removal device for wind power tower processing. Background Art

[0002] Wind towers, also known as wind turbine towers, are key components in wind power generation systems. They are mainly used to support wind turbines and enable them to capture more wind energy at high altitudes and then convert it into electrical energy. After long-term use, the surface of the wind tower is prone to rust and needs to be derusted. Rust removal equipment for wind tower processing is required.

[0003] In the prior art, there are the following problems:

[0004] Usually, when removing rust from a wind turbine tower, workers usually have to climb to the rusted position of the wind turbine tower and use handheld rust removal equipment to remove rust from the wind turbine tower. There are great safety hazards during rust removal. It is inconvenient to fix the rust removal device on the outside of the wind turbine tower, it is inconvenient to splice and disassemble the rust removal equipment, and it is inconvenient to make the rust removal device automatically detect and remove rust from the surface of the wind turbine tower. Utility Model Content

[0005] The purpose of the utility model is to provide a rust removal device for wind power tower processing to solve the problems raised in the above background technology.

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] By clamping the two bearing frames on the periphery of the wind turbine tower, the two support plates are aligned with the two fixed plates respectively, and by driving the movable plate to flip, the threaded rod is synchronously driven to flip to the inside of the fixed plate, so that the threaded sleeve is located on the right side of the fixed plate, and by driving the threaded rod to rotate, the threaded sleeve is engaged with the threaded rod, which can drive the threaded sleeve to move to the left, and the support plate and the fixed plate can be driven to move together, and the two bearing frames can be driven to move together at the same time, so that the bearing frames can be conveniently spliced on the periphery of the wind turbine tower, and by driving the bearing frames to move up and down along the wind turbine tower, by moving the bearing frames to the rusted position, and then driving the fixing box to move to the wind turbine tower. The outside of the rusted position is driven by the support frame to move inward so that the grinding belt contacts the rusted position, and then the grinding belt is driven to rotate to grind and remove rust from the wind turbine tower. The rusted position of the wind turbine tower can be automatically removed by the support wheel. The support wheel rolls along the outer wall of the wind turbine tower. When the support frame moves upward to change the diameter of the wind turbine tower at different positions, the support wheel drives the displacement sensor to extend and retract, and then drives the threaded rod to rotate, so that the two support frames are closed or separated, so that the driving wheel is always in squeeze contact with the outer wall of the wind turbine tower, avoiding separation from the driving wheel when the diameter of the wind turbine tower changes at different heights.

[0008] Preferably, a plurality of scanners are fixedly mounted on the inner sides of the two carriers, and a mounting plate is fixedly connected to the outer sides of the two carriers. The scanners can be used to scan and detect rusted areas of the wind turbine tower, and the mounting plate can be used to install and fix the battery and control equipment.

[0009] Preferably, two support blocks are fixedly mounted on the top and bottom of the two carriers, and a driving wheel is rotatably mounted on the inner side of the plurality of support blocks. The driving wheel can be supported by the support blocks, so that the driving wheel can be easily rotated.

[0010] Preferably, each displacement sensor is fixed to the support frame via a fixing block, and a thrust spring is fixedly connected between each fixing block and the support wheel, with each thrust spring being located on the periphery of a displacement sensor. The fixing block supports and secures the displacement sensor, and the thrust of the thrust spring ensures that the support wheel is always in contact with the outer wall of the wind turbine tower.

[0011] Preferably, two movable rods are fixedly mounted on the outer sides of the two support frames, one end of each movable rod extends into the inner side of a fixed sleeve and is slidably mounted with the fixed sleeve, and an electric telescopic rod is fixedly connected between one end of each movable rod and a fixed sleeve. The electric telescopic rod can drive the movable rod to extend and retract along the fixed sleeve, and can synchronously drive the support frame to move left and right.

[0012] Preferably, three support rollers are rotatably mounted on the inner side of each of the fixed boxes, and each of the three support rollers is rollingly supported by a track frame. Two fixing rods are fixedly mounted on one side of each of the support plates, and each of the two fixing rods passes through a fixed plate and is slidably connected to the fixed plate. The support rollers are rollingly supported by the track frames, so that the support rollers are fixed along the track frames during rotation, thereby driving the fixed boxes to move along the track frames. The fixing rods can limit the position between the support plate and the fixed plate, preventing the support plate and the fixed plate from tilting.

[0013] The present invention provides a rust removal device for processing a wind turbine tower. Compared with the prior art, the present invention has the following beneficial effects: by providing a support plate, a fixed plate, a fixed box and a support frame, two supporting frames are clamped on the periphery of the wind turbine tower, the two supporting plates are aligned with the two fixed plates respectively, and then the threaded rod is flipped to the inside of the fixed plate, so that the threaded sleeve is located on the right side of the fixed plate, and by driving the threaded rod to rotate and utilizing the threaded sleeve to engage with the threaded rod, the two supporting frames can be moved together, so that the driving wheel contacts the wind turbine tower, and the supporting frames can be conveniently spliced on the periphery of the wind turbine tower. At the same time, the supporting frames can be conveniently moved up and down along the wind turbine tower. When the supporting frames are moved to the rusted position, the rusted position is moved by driving the fixed box to move, and the supporting frames are driven to move inward so that the grinding belt contacts the rusted position. By driving the grinding belt to rotate, the rusted position of the wind turbine tower can be automatically rust-removed. BRIEF DESCRIPTION OF THE DRAWINGS
