Description

Technical Field

[0001] This utility model relates to the field of wind turbine installation technology, specifically a tower support fixture for wind turbine installation. Background Technology

[0002] With the continuous development of offshore wind turbines, the turbine models are gradually becoming larger, and the diameter variation range of the tower of large turbines is increasing. This places higher demands on the compatibility of the tower support fixtures. The tower is generally composed of 3-4 sections connected by flanges. The compatibility and adaptability between the tower and its storage / transport fixtures directly affect the degree of tower deformation. The greater the compatibility of the fixtures, the smaller the tower deformation rate.

[0003] As the size of wind turbine towers continues to increase, the main and auxiliary cranes of the operating vessels can no longer directly complete the tower turning and lifting operations on the barge. The current standard procedure is to first transfer the tower to the deck via the main crane, and after the turning operation is completed, two sets of arc-shaped jigs are set up on the deck. Finally, the crane is used to place the tower stably on the jigs, which creates convenient conditions for the subsequent assembly of multiple tower sections.

[0004] However, during the process of placing the tower section onto the arc-shaped jig, the length and center of gravity of each tower section differ. This requires adjusting the position of the arc-shaped jig to ensure that the centers of the two jigs are on the same straight line. This operation not only significantly increases the workload of the workers but also prolongs the overall installation time of the tower. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tower support fixture for wind turbine installation, which can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A tower support fixture for wind turbine installation includes: The bracket has a fixed frame on one side and three sets of sliding grooves evenly opened on the inner side of the bracket. The adjustment component includes a support frame, sliders, pins, and cleaning components. Three sets of sliders are evenly arranged at the bottom of the support frame. Pins are symmetrically arranged on the inner side of the sliders. Multiple sets of insertion holes are evenly arranged on the bottom side of the slide groove. The pins are inserted into the insertion holes. The replacement components include the tire frame body, positioning blocks, and fixing parts. The top inner side of both the fixing frame and the support frame is provided with positioning grooves, and positioning blocks are symmetrically arranged at the bottom of the tire frame body. The positioning blocks are inserted into the positioning grooves.

[0007] Furthermore, the cleaning component includes a push plate, a push plate is provided on one side of the slider, and an inclined groove is provided at the bottom of one end of the slide.

[0008] Furthermore, two sets of limiting grooves are symmetrically provided at one end of the chute, and limiting blocks are slidably arranged inside the limiting grooves, with a collection box provided on one side of the limiting blocks.

[0009] Furthermore, the fixing component includes a threaded hole inside one side of the support frame, a screw threaded inside the threaded hole, and a handle at one end of the screw.

[0010] Furthermore, a connecting plate is rotatably provided on the outer side of the screw, and two sets of fixing rods are symmetrically provided on one end of the connecting plate. A through groove is provided through the inner side of the positioning groove, and a fixing groove is provided through the inner side of the positioning block. The fixing rods are inserted into the through groove and the fixing groove.

[0011] Compared with the prior art, the beneficial effects of this utility model include: 1. By sliding the slider in the groove and inserting the pin into different holes, the position of the support frame and the top jig body can be freely adjusted to meet the support requirements of towers of different lengths and center of gravity positions. There is no need to change the entire set of tooling. When the push plate moves with the slider, it can scrape off impurities in the groove. The impurities fall into the collection box through the inclined groove, which avoids the accumulation of impurities that may cause the slider to slide and jam, ensuring that the adjustment function is smooth for a long time. The collection box is detachably connected to the limit block and the limit groove. When the box is full, it can be quickly disassembled and transferred to achieve centralized treatment of impurities and reduce the workload of manual cleaning. 2. The jig body is quickly positioned and installed using positioning blocks and positioning slots, eliminating the need for complex alignment operations. Matching jig bodies can be quickly replaced according to different tower specifications, improving the versatility of the tooling. The fixing rod is inserted into the fixing slot of the positioning block by the screw and connecting plate, which can firmly fix the jig body on the fixing frame and support frame, preventing the jig body from shifting when the tower is placed or under stress, ensuring the stability of the support. The extension and retraction of the fixing rod can be completed by simply turning the handle, without the need for professional tools. A single worker can operate it, reducing the operation threshold and time cost. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1 - Figure 9 As shown, this utility model provides a tower support fixture for wind turbine installation, comprising: The bracket 102 has a fixed frame 101 on one side, and three sets of sliding grooves 204 are evenly opened on the inner side of the bracket 102. The adjustment component 200 includes a support frame 103, sliders 209, pins 202, and cleaning components. Three sets of sliders 209 are evenly arranged at the bottom of the support frame 103. Pins 202 are symmetrically slidably arranged on the inner side of the sliders 209. Multiple sets of insertion holes 205 are evenly arranged on the bottom side of the inner side of the slide groove 204. The pins 202 are inserted into the inner side of the insertion holes 205. The replacement component 300 includes a tire frame body 104, a positioning block 303, and a fixing component. The top inner side of the fixing frame 101 and the support frame 103 are both provided with positioning grooves 305. The bottom of the tire frame body 104 is symmetrically provided with positioning blocks 303, which are inserted into the inner side of the positioning grooves 305.

[0017] In the above scheme: 1. By moving the slider 209 within the slide groove 204, the push plate 201 can be driven to clean the inside of the slide groove 204, thereby achieving the cleaning of the inside of the slide groove 204. 2. By controlling the insertion of the pin 202 into the inner side of the socket 205, the position of the support frame 103 can be fixed, which facilitates the stable placement of towers of different lengths. 3. The device can be replaced by the frame body 104, which makes it easier to place towers of different diameters, making the device more practical.

[0018] In this embodiment, the cleaning component includes a push plate 201 on one side of the slider 209, and an inclined groove 206 at the bottom of one end of the slide groove 204.

[0019] In the above scheme: after the tooling has been used for a long time, sand, metal shavings and other impurities accumulate in the chute 204. At this time, the worker pushes the support frame 103 from the initial position close to the fixed frame 101 to the right. The slider 209 drives the push plate 201 to slide synchronously along the chute 204. The push plate 201 scrapes and pushes the impurities in the chute to the right until the impurities are pushed to the entrance of the inclined chute 206. Under the action of gravity, the impurities slide down the inclined surface of the inclined chute 206 to the external collection device, completing the cleaning operation of the chute 204 and effectively avoiding the accumulation of impurities that cause the slider 209 to slide and get stuck.

[0020] In this embodiment, two sets of limiting grooves 207 are symmetrically provided at one end of the slide groove 204, and a limiting block 208 is slidably provided inside the limiting groove 207. A collection box 203 is provided on one side of the limiting block 208.

[0021] In the above scheme: when a large amount of impurities have been collected in the collection box 203, the staff will pull the collection box 203 vertically upwards. The limiting block 208 will slide upwards along the limiting groove 207 and disengage from the groove, so that the collection box 203 can be removed and transferred to the designated waste area for impurity dumping. After cleaning, the limiting block 208 will be aligned with the limiting groove 207 and inserted to complete the reset and installation of the collection box 203. The operation is convenient and efficient.

[0022] In this embodiment, the fixing component includes a threaded hole 309 inside one side of the support frame 103, a screw 307 threaded inside the threaded hole 309, and a handle 302 at one end of the screw 307.

[0023] In the above scheme: after the jig body 104 is initially positioned by the positioning block 303 and the positioning groove 305, the worker holds the handle 302 and rotates it clockwise, which drives the screw 307 to screw in along the threaded hole 309. The axial movement of the screw 307 drives the subsequent fixing structure to achieve the fastening of the jig body 104 and prevent the jig body 104 from shifting when the tower is placed.

[0024] In this embodiment, a connecting plate 301 is rotatably provided on the outer side of the screw 307. Two sets of fixing rods 306 are symmetrically provided on one end of the connecting plate 301. A through groove 308 is provided through the inner side of the positioning groove 305. A fixing groove 304 is provided through the inner side of the positioning block 303. The fixing rods 306 are inserted into the inner side of the through groove 308 and the fixing groove 304.

[0025] In the above scheme: when installing the jig body 104, after inserting the positioning block 303 into the positioning groove 305, the fixing groove 304 and the through groove 308 are automatically aligned. At this time, turn the handle 302 clockwise, and the screw 307 is screwed into the threaded hole 309, pushing the connecting plate 301 to move towards the positioning groove 305. The connecting plate 301 drives the two sets of fixing rods 306 to pass through the through groove 308 and insert into the fixing groove 304 respectively. When the handle 302 is rotated to the point where it can no longer be rotated, the fixing rods 306 and the fixing groove 304 are tightly engaged to achieve rigid fixation of the jig body 104.

[0026] In this embodiment, when the tower needs to be placed on the jig body 104, the operator first inserts the positioning block 303 at the bottom of the jig body 104 into the positioning groove 305 according to the tower's specifications. At this time, the fixing groove 304 and the fixing rod 306 are aligned. The operator then turns the handle 302, which drives the screw 307 into the threaded hole 309. This allows the two sets of fixing rods 306 to slide in the through groove 308 through the connecting plate 301 until they slide into the fixing groove 304, thus fixing the position of the jig body 104. This allows the jig body 104 to stably support the tower. Then, according to the length and center of gravity of the tower, the operator pushes the support frame 103, which allows the slider 209 to... The slide 204 slides to a designated position, and then the operator adjusts the position of the frame body 104 by inserting the control pin 202 into the insertion hole 205. This facilitates the support of towers of different lengths. After the slide 204 has been used for a long time, the operator pushes the support frame 103 from the position of the fixed frame 101 to the side of the slide 204 near the inclined groove 206. The push plate 201 can scrape off the impurities inside the slide 204, allowing the impurities to slide through the inclined groove 206 into the inside of the collection box 203. When a lot of impurities have been collected inside the collection box 203, the operator pulls the collection box 203 upwards, causing the limiting block 208 to disengage from the inside of the limiting groove 207. This allows the operator to move the collection box 203 to another location for centralized processing of the impurities.
