Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower production technology, specifically an adjustable movable tooling for welding wind turbine towers. Background Technology

[0002] With the increasing global demand for clean energy, wind power generation has been widely developed as an important form of renewable energy utilization. As a key supporting component of wind turbine generators, the manufacturing quality of the wind turbine tower directly affects the safe and stable operation of the wind turbine generator set.

[0003] In the manufacturing process of wind turbine towers, multiple towers need to be welded together. Therefore, a moving fixture is required during welding. Currently, existing moving fixtures have relatively simple structures. They typically support the wind turbine towers and then move along ground tracks to connect them. However, over time, the moving fixture may shift its support, causing errors in the concentricity of the towers during connection. Existing moving fixtures can only adjust one end of the tower vertically, not horizontally. Therefore, when the tower deviates horizontally, manual adjustment is necessary. Due to the large mass of the wind turbine towers, manual adjustment is laborious and difficult, reducing the accuracy of tower adjustment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable movable tooling for welding wind turbine towers. This tooling solves the problem of inconvenient horizontal adjustment during the use of traditional wind turbine tower movable tooling, and eliminates the need for manual adjustment of the wind turbine tower by workers. This reduces the adjustment difficulty for workers, improves the accuracy of concentricity adjustment of the wind turbine tower, and further improves the welding quality and production quality of the wind turbine tower.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable movable tooling for welding wind turbine towers, comprising a base, a groove on the upper surface of the base, a movable block slidably connected inside the groove, a reset mechanism at both ends of the movable block, a movable plate fixedly connected to the upper surface of the movable block, drag reduction mechanisms symmetrically arranged on both sides of the groove on the upper surface of the base, and movable wheels symmetrically installed on the lower surface of the base, a limiting frame on the upper surface of the movable plate, a horizontal plate symmetrically fixedly connected to both ends of the limiting frame, a lifting mechanism on the lower surface of the horizontal plate, a slider symmetrically slidably connected inside the limiting frame, a roller fixedly connected to the upper surface of the slider, a double-ended lead screw threaded inside the slider, a motor fixedly connected to one end of the double-ended lead screw passing through the limiting frame, a support box fixedly connected to one end of the base, a toggle block on the upper surface of the support box, the toggle block being aligned with one end of the movable plate, and a drive mechanism connected to the lower surface of the toggle block.

One end of the worm is rotatably connected to the inner side wall of the support box, and the upper end of the driving shaft passes through the support box and is fixedly connected to the lower surface of the toggle block.

[0007] Preferably, the reset mechanism includes a side plate, which is fixedly connected to the inner wall of the slide groove. A spring is fixedly connected to the inner surface of the side plate, and one end of the spring is fixedly connected to one end of the moving block.

[0008] Preferably, the drag reduction mechanism includes grooves, which are symmetrically distributed on the upper surface of the base. A roller is rotatably connected inside the groove, and the side surface of the roller contacts the lower surface of the moving plate.

[0011] This utility model provides an adjustable and movable tooling for welding wind turbine towers. Compared with the prior art, it has the following advantages:

[0013] 2.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: an adjustable movable tooling for welding wind turbine towers, including a base 1. A groove 101 is formed on the upper surface of the base 1. A movable block 106 is slidably connected inside the groove 101. Reset mechanisms are provided at both ends of the movable block 106. A movable plate 2 is fixedly connected to the upper surface of the movable block 106. Drag-reducing mechanisms are symmetrically arranged on both sides of the groove 101 on the upper surface of the base 1. Movable wheels 102 are symmetrically installed on the lower surface of the base 1. A limiting frame 201 is provided on the upper surface of the movable plate 2, and the two ends of the limiting frame 201 are symmetrically fixed. A horizontal plate 4 is connected, and a lifting mechanism is provided on the lower surface of the horizontal plate 4. A slider 204 is symmetrically slidably connected inside the limiting frame 201. A roller 203 is fixedly connected to the upper surface of the slider 204. A two-way lead screw 202 is threaded inside the slider 204. One end of the two-way lead screw 202 passes through the limiting frame 201 and is fixedly connected to a motor 205. A support box 3 is fixedly connected to one end of the base 1. A toggle block 301 is provided on the upper surface of the support box 3. The toggle block 301 is aligned with one end of the moving plate 2. A drive mechanism is connected to the lower surface of the toggle block 301.

[0021] As a technical optimization of this utility model, the driving mechanism includes a driving shaft 303. The lower end of the driving shaft 303 is rotatably connected to the inner wall of the support box 3. A worm gear 304 is fixedly connected to the side surface of the driving shaft 303. A worm 302 is meshed with the side surface of the worm gear 304. One end of the worm 302 is rotatably connected to the inner side wall of the support box 3. The upper end of the driving shaft 303 passes through the support box 3 and is fixedly connected to the lower surface of the actuating block 301. The worm 302, driving shaft 303 and worm gear 304 in the driving mechanism can drive the actuating block 301 to rotate. The actuating block 301 can push the moving plate 2 to move horizontally.

[0022] As a technical optimization of this utility model, the reset mechanism includes a side plate 107, which is fixedly connected to the inner wall of the slide groove 101. A spring 105 is fixedly connected to the inner surface of the side plate 107, and one end of the spring 105 is fixedly connected to one end of the moving block 106. Through the spring 105 and the side plate 107 in the reset mechanism, the moving plate 2 can be restored to its original position after the wind turbine tower is welded, so as to facilitate its use next time.

[0023] As a technical optimization of this utility model, the drag reduction mechanism includes a groove 103, which is symmetrically distributed on the upper surface of the base 1. A roller 104 is rotatably connected inside the groove 103. The side surface of the roller 104 contacts the lower surface of the moving plate 2. Therefore, when the moving plate 2 is adjusted by the drive mechanism, the friction between the moving plate 2 and the base 1 can be reduced, thereby reducing the force required for the moving plate 2 to move horizontally.

[0024] As a technical optimization of this utility model, the lifting mechanism includes an airbag 402. The upper end of the airbag 402 is fixedly connected to the lower surface of the horizontal plate 4, and the lower surface of the airbag 402 is fixedly connected to the upper surface of the moving plate 2. An air guide pipe 403 is fixedly installed on the side surface of the airbag 402. The limit frame 201 can be adjusted up and down by the airbag 402 and the air guide pipe 403 in the lifting mechanism, so the concentricity of the wind turbine tower in the vertical direction can be adjusted.

[0025] As a technical optimization of this utility model, a limiting rod 401 is slidably connected inside the horizontal plate 4. The lower end of the limiting rod 401 is fixedly connected to the upper surface of the moving plate 2. The limiting rod 401 can limit the limiting frame 201, prevent the limiting frame 201 from shaking during the rising or falling process, and improve the support stability of the wind turbine tower.

[0026] In use, the operator first starts the motor 205, which adjusts the distance between the slider 204 and the roller 203 via the bidirectional lead screw 202. Then, the wind turbine tower to be connected is hoisted onto the inner side of the roller 203. The operator then moves the wind turbine tower using the movable wheels 102 on the lower surface of the base 1 for connection. If the concentricity of the wind turbine tower shifts horizontally during connection, the operator rotates the worm gear 302 according to the shift. The worm gear 302 then drives the drive shaft 303 and the worm wheel 304 to rotate. The worm wheel 304 then drives the actuating block 301 to rotate. One end of 01 will be against one end of the moving plate 2, and at the same time push the moving plate 2 to move horizontally. When the concentricity of the wind turbine tower is aligned, the rotation of the worm gear 302 will stop. When it is necessary to adjust the concentricity of the wind turbine tower in the vertical direction, air will be injected into the air bag 402 through the air guide pipe 403. At this time, the air bag 402 will lift the limit frame 201 and the wind turbine tower through the horizontal plate 4, thereby aligning the wind turbine tower. After the wind turbine tower welding is completed, the worker will rotate the worm gear 302 in the opposite direction. At this time, the worm gear 302 will drive the worm wheel 304 and the actuating block 301 to return to their original positions. At the same time, the moving plate 2 will also return to its original position under the action of the moving block 106 and the spring 105.
