Description

Technical Field

[0001] The utility model belongs to the technical field of tower barrel installation, and particularly relates to a scraping tool for epoxy glue overflow at the horizontal joint during the installation of a C-shaped hybrid tower barrel of a wind turbine generator set. Background Technique

[0002] The manufacturing of wind power products belongs to the field of renewable energy technology, which has the advantages of environmental protection, energy conservation, and huge development potential. The wind turbine tower barrel is the main supporting component of a wind turbine generator set. Its main function is to support the main engine and impeller of the wind turbine to a specified working height. On the one hand, it ensures that the wind turbine can utilize enough wind energy, and on the other hand, it also prevents itself from tipping over due to the action of the nacelle gravity and wind force.

[0003] Commonly used wind power support towers include all-steel tower barrels, truss towers, steel-concrete component tower barrels, etc. With the continuous development of the wind power market, the height of wind turbine tower barrels is getting higher and higher. Due to the current technical level limitations, there are many unsolved problems with flexible all-steel high tower barrels. Therefore, each wind turbine manufacturer has introduced the steel-concrete combined tower barrel technology. Among them, Haizhuang Wind Power Company has developed a hybrid tower composed of 4 identical C-shaped concrete components spliced together for each section. The vertical joints between adjacent hybrid tower components and the horizontal joints between adjacent upper and lower hybrid tower components need to be bonded with a layer of epoxy glue to keep the components stressed evenly and prevent water seepage. During the construction of the hybrid tower, when two layers of hybrid tower components are stacked, the excess epoxy glue will overflow from the horizontal joint. Therefore, solving the problem of the appearance flow marks caused by the epoxy glue overflow has become an important link in on-site construction.

[0004] When each section of the hybrid tower is assembled, the excess epoxy glue overflowing from the vertical joint can be cleaned on the ground platform. It should be noted that: the epoxy glue overflowing from the horizontal joint will overflow simultaneously on the inner and outer circles of the tower barrel. When the entire section of the hybrid tower is hoisted, the epoxy glue overflowing from the horizontal joint on the inner circle can be cleaned and scraped by construction workers standing on the temporary hoisting platform inside the tower. However, for the epoxy glue overflowing from the outer circle, construction workers cannot reach the external horizontal joint position for cleaning, and the epoxy glue remaining on the outer wall of the tower barrel will seriously affect the appearance quality of the tower barrel. At the same time, the setting time of the epoxy glue is limited. If it is not cleaned up in time, the flow marks of the epoxy glue overflowing from the horizontal joint will dry and solidify permanently.

[0005] Based on this, the applicant considered designing a scraping tool for epoxy glue overflow at the horizontal joint during the installation of a C-shaped hybrid tower barrel of a wind turbine generator set. Content of the Utility Model

[0006] Aiming at the deficiencies of the above-mentioned existing technology, the technical problem to be solved by the present invention is: how to provide a scraping tool for epoxy glue overflow at the horizontal joint during the installation of a C-shaped hybrid tower barrel of a wind turbine generator set.

[0008] A scraping tool for removing epoxy glue overflow from the horizontal joint during the installation of the C-shaped mixed tower tower barrel of a wind turbine, comprising a fixed clamping arm, a movable clamping arm, an adjusting mechanism, a limiting and rebounding mechanism, and a scraping rod. The fixed clamping arm and the movable clamping arm are arranged oppositely and can form a clamping area with each other. The adjusting mechanism is installed between the fixed clamping arm and the movable clamping arm and is used to adjust the clamping distance between the fixed clamping arm and the movable clamping arm. The limiting and rebounding mechanism is installed outside the fixed clamping arm. The scraping rod is installed on the limiting and rebounding mechanism and can slide up and down along the limiting and rebounding mechanism. The limiting and rebounding mechanism can make the scraping rod reset upward after the scraping rod moves downward.

[0009] Compared with the prior art, the advantages of the scraping tool for removing epoxy glue overflow from the horizontal joint during the installation of the C-shaped mixed tower tower barrel of a wind turbine of the present utility model are as follows:

[0027] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] During specific implementation: As Figures 1-7 shown, a scraping tool for overflowing transverse joint epoxy glue during the installation of a C-type hybrid tower barrel of a wind turbine includes a fixed clamping arm, a movable clamping arm, an adjusting mechanism, a limiting and rebounding mechanism, and a scraping rod. The fixed clamping arm and the movable clamping arm are arranged oppositely and can form a clamping area with each other. The adjusting mechanism is installed between the fixed clamping arm and the movable clamping arm and is used to adjust the clamping distance between the fixed clamping arm and the movable clamping arm. The limiting and rebounding mechanism is installed outside the fixed clamping arm. The scraping rod is installed on the limiting and rebounding mechanism and can slide up and down along the limiting and rebounding mechanism. The limiting and rebounding mechanism can make the scraping rod reset upward after the scraping rod moves downward.

[0029] Compared with the prior art, the advantages of the scraping tool for overflowing transverse joint epoxy glue during the installation of a C-type hybrid tower barrel of a wind turbine of the present utility model are:

[0030] By setting the fixed clamping arm, movable clamping arm, adjusting mechanism, limiting and rebounding mechanism and the shovel rod, the shovel rod can be erected on the outer wall of the tower barrel, and the distance between the fixed clamping arm and the movable clamping arm can be adjusted to adapt to different wall thicknesses of the tower barrel. At the same time, the limiting and rebounding mechanism can assist the shovel rod to perform reciprocating movement up and down and rebound the shovel rod upward for resetting, so as to save manpower, make the cleaning more convenient and fast, and enable the construction personnel to clean without reaching the horizontal seam position where the epoxy glue overflows on the outer ring, with the cleaning being fast, simple and safe, and reducing the influence of the residual epoxy glue on the outer wall of the tower barrel on the appearance quality of the tower barrel.

[0031] The above-mentioned scraping tool for the epoxy glue overflowing at the horizontal seam during the installation of the C-type mixed tower barrel of the wind turbine has the advantages of simple structure and easy implementation, is suitable for installation and use when cleaning the epoxy glue at the horizontal seam on the outer wall of the existing wind turbine tower barrel, and has a low use cost and can improve the efficiency.

[0032] In this embodiment, as Figures 1-7 shown, the fixed clamping arm includes an outer arm 110 and a top plate 120. The top plate 120 includes opposite outer edges and inner edges. The top end of the outer arm 110 is fixedly connected to the outer edge. A sliding track is provided on the bottom surface of the top plate 120, and the sliding direction of the sliding track is perpendicular to the outer arm 110. The movable clamping arm is installed in the sliding track and can slide along the sliding track.

[0033] In this way, by setting the outer arm 110 and the top plate 120, the fixed clamping arm is in a right-angled shape, can be supported on the top surface of the horizontal seam of the tower barrel and the outer wall of the tower barrel, has a relatively simple structure and a more comprehensive supporting effect.

[0034] In this embodiment, as Figures 1-7 shown, the movable clamping arm includes an inner arm 210 and a sliding plate 220. The sliding plate 220 includes opposite limiting ends and connecting ends. The sliding plate 220 is slidably arranged in the sliding track. The limiting end faces the outer edge, and the connecting end faces the inner edge. The sliding track includes two straight groove arms 121 respectively arranged on both side edges of the bottom surface of the top plate 120. The notch directions of the two straight groove arms 121 are arranged opposite to each other, and a channel is formed between the two straight groove arms 121. The top end of the inner arm is fixedly connected to the connecting end of the sliding plate 220 through the channel.

[0035] In this way, by setting the inner arm 210 and the sliding plate 220, the movable clamping arm is in a right-angled shape, can be supported on the top surface of the horizontal seam of the tower barrel and the inner wall of the tower barrel, has a relatively simple structure and a more comprehensive supporting effect, and through the setting of the sliding plate 220, the inner arm can move relatively smoothly and stably with respect to the outer arm 110.

[0036] In this embodiment, as Figures 1-7As shown, the adjustment mechanism includes a first motor 310 and a transmission shaft 320. The first motor 310 is installed on the bottom surface of the top plate 120 and is close to the outer edge. One end of the transmission shaft 320 is coaxially connected to the rotating shaft of the first motor 310, and the other end extends to the inner edge of the top plate 120. A threaded hole is provided on the inner arm, and a thread is provided on the transmission shaft 320. The inner arm is threadedly connected to the transmission shaft 320 through the threaded hole.

[0037] In this way, by providing the first motor 310 and the transmission shaft 320 , the first motor 310 drives the inner arm 210 to move along the top plate 120 through the transmission shaft 320 , the adjustment structure is relatively simple, and the threaded transmission is more reliable.

[0038] In this embodiment, Figures 1-7 As shown, a first pulley group is provided on the fixed clamp arm, and the first pulley group is provided between the fixed clamp arm and the tower, and is used to support the fixed clamp arm. A second pulley group is provided on the movable clamp arm, and the second pulley group is provided between the movable clamp arm and the tower, and is used to support the movable clamp arm.

[0039] In this way, by setting the first pulley group and the second pulley group, the fixed clamp arm and the movable clamp arm can move in a circle along the tower wall to clean the glue overflow from the transverse seams at different positions on the outer wall of the tower, with high adaptability and improved cleaning efficiency.

[0040] In this embodiment, Figures 1-7 As shown, the first pulley block includes a first vertical support pulley 410 and a first transverse guide pulley 420. The first vertical support pulley 410 is fixedly mounted on the bottom surface of the top plate 120 and can abut against the top surface of the transverse seam of the tower. The first transverse guide pulley 420 is fixedly mounted on the inner side of the outer arm 110 and can abut against the outer wall of the tower.

[0041] In this way, by providing the first vertical support pulley 410 and the first transverse guide pulley 420 , the fixed clamp arm can be supported by the first vertical support pulley 410 in the vertical direction, and can be guided and supported by the first transverse guide pulley 420 in the transverse direction.

[0042] In this embodiment, Figures 1-7 As shown, the second pulley block includes a second vertical support pulley 510 and a second transverse guide pulley 520. The second vertical support pulley 510 is fixedly mounted on the bottom surface of the slide plate 220 and can abut against the top surface of the transverse seam of the tower. The second transverse guide pulley 520 is fixedly mounted on the inner side of the inner arm 210 and can abut against the inner wall of the tower.

[0043] In this way, through the arranged second vertical support pulley 510 and the second horizontal guide pulley 520, the movable clamping arm can be supported by the second vertical support pulley 510 in the vertical direction and can be guided and supported by the second horizontal guide pulley 520 in the horizontal direction.

[0044] In this embodiment, as Figures 1-7 shown, the limit and resilience mechanism includes a limit ring 610, a reset ring 620 and a tension spring 630. The limit ring 610 is fixedly installed at the middle of the outer bottom of the outer arm 110, and the orifice of the limit ring 610 is arranged vertically. There are two reset rings 620. The two reset rings 620 are arranged oppositely on the outer top of the outer arm 110 with the axis of the orifice of the limit ring 610 as the center line. The shovel rod vertically penetrates through the orifice of the limit ring 610. Two hooks 640 are arranged on the outer wall of the shovel rod. There are two tension springs 630. The two ends of each tension spring 630 are respectively connected to a corresponding reset ring 620 and a hook 640 on the same side.

[0045] In this way, through the arranged limit ring 610, reset ring 620 and tension spring 630, when the shovel rod moves up and down to scrape the overflowing epoxy glue, its position can be limited by the limit ring 610 and it is not easy to scrape off-target. At the same time, the reset ring 620 and the tension spring 630 can automatically apply a reset elastic force to the shovel rod after it moves downward to assist the shovel rod in resetting to continue scraping downward. The structure is simple and the efficiency is relatively high.

[0046] In this embodiment, as Figures 1-7 shown, the shovel rod includes a grip part 710, a limit rod part 720 and a cleaning rod part 730 which are connected in sequence from top to bottom. Anti-slip patterns are arranged on the grip part 710. The two hooks 640 are symmetrically arranged on the limit rod part 720. A shovel head is arranged at the bottom end of the cleaning rod part.

[0047] In this way, through the arranged grip part 710, limit rod part 720 and cleaning rod part 730, the shovel rod can be disassembled and reassembled to adjust and replace different scraping lengths to adapt to tower barrels of different heights. At the same time, the anti-slip patterns can prevent the operator from slipping accidentally during use and improve safety.

[0048] In this embodiment, as Figures 1-7 shown, the shovel rod further includes two double-headed bolts 740. One of the double-headed bolts 740 is arranged between the grip part 710 and the limit rod part 720 for connecting the grip part 710 and the limit rod part 720. The other double-headed bolt 740 is arranged between the limit rod part 720 and the cleaning rod part 730 for connecting the limit rod part 720 and the cleaning rod part 730.

[0049] In this way, through the two double-headed bolts 740 provided, the connection between the grip rod portion 710, the limit rod portion 720 and the cleaning rod portion 730 is more reliable, the disassembly is relatively convenient, and the connection is more stable.

[0050] During implementation, a first connection cavity is provided at the bottom end of the grip rod portion 710, a second connection cavity is provided at the top end of the limit rod portion 720. The first connection cavity and the second connection cavity are arranged oppositely and both are provided with internal threads. The threaded heads at both ends of one of the double-headed bolts 740 are threadedly connected to the first connection cavity and the second connection cavity respectively.

[0051] During implementation, a third connection cavity is provided at the bottom end of the limit rod portion 720, a fourth connection cavity is provided at the top end of the cleaning rod portion 730. The third connection cavity and the fourth connection cavity are arranged oppositely and both are provided with internal threads. The threaded heads at both ends of the other double-headed bolt 740 are threadedly connected to the third connection cavity and the fourth connection cavity respectively.

[0052] The above is only the preferred implementation mode of the present invention. It should be noted that for those skilled in the art, without departing from the premise of this technical solution, several deformed and improved technical solutions should be equally regarded as falling within the scope protected by this claim book.
