Description

Technical Field

[0001] The present application relates to the field of anti-corrosion treatment of wind turbine towers, and in particular to an automatic thermal zinc spraying device for offshore wind turbine towers. Background Art

[0002] The production process of wind turbine tower is generally as follows: CNC cutting machine cuts the material, thick plate needs to be beveled, plate rolling machine rolls the plate into shape, spot welding, positioning, and after confirmation, the inner and outer longitudinal seams are welded. After the roundness is checked, if there is a problem, a secondary rounding is performed. After the welding of a single section of the cylinder is completed, the hydraulic group is used to assemble the roller frame for spot welding, the inner and outer circumferential seams are welded, and after the straightness and other tolerances are checked, the flange is welded, non-destructive testing of the weld and flatness inspection are carried out, the outer surface of the single section of the cylinder is zinc sprayed, and finally the internal parts are installed and the finished product is inspected and transported to the installation site.

[0003] The zinc spraying treatment of the tower is an important process in the production and manufacturing of the tower. The zinc spraying treatment can spray a zinc layer on the surface of the tower to play a protective role and effectively prevent the tower from corrosion.

[0004] In the prior art, the zinc spraying operation of the tower is mainly completed by supporting rollers and spray guns. The tower is placed on the supporting rollers, which drive the tower to rotate, and then the zinc spraying operation is performed manually with a handheld spray gun.

[0005] During the above process, the support roller supports the tower and drives it to rotate, so that the area where the support roller contacts the tower becomes a blind area for zinc spraying. After the zinc spraying operation on other parts of the tower is completed, the zinc layer is dry and solid, and the tower needs to be moved to re-spray the blind area for zinc spraying. The zinc spraying operation is difficult to complete in one go, the efficiency of the zinc spraying operation is reduced, and it is easy to cause differences in the thickness of the zinc layer of the entire tower. Summary of the Invention

[0006] In order to solve the problems existing in the above-mentioned technology, the present application provides an automatic thermal zinc spraying device for offshore wind power tower.

[0007] The present application provides an automatic thermal zinc spraying device for an offshore wind power tower, which adopts the following technical solutions:

[0008] An automatic hot zinc spraying device for an offshore wind power tower comprises two support members, which are respectively arranged at the two ends of the tower and are in contact with the tower flange surface. A linear guide rail is provided between the two support members, and a power part is slidably provided on the linear guide rail along the length direction. The power part is provided with an annular guide rail, and a plurality of zinc spraying parts are provided on the inner side of the annular guide rail.

[0009] By adopting the above technical solution, the device supports and fixes the tower through two support members, and the two support members are connected to the flange surface of the tower, so that the outer surface of the tower can be fully exposed; in the initial state, the annular guide rail is located at one end of the linear guide rail to control the operation of the zinc spraying part, and the zinc spraying part sprays zinc on the surface of the tower. At the same time, the power unit slides on the linear guide rail, thereby driving the annular guide rail to move. When the annular guide rail moves to the other end of the linear guide rail, the zinc spraying part completes the zinc spraying treatment on the outer surface of the tower; the cooperation of various components in the above process enables the zinc spraying operation of the tower to be completed at one time, thereby improving the efficiency of the zinc spraying operation, and the thickness of the zinc layer after spraying is consistent. At the same time, the automation of the zinc spraying operation is realized, further reducing the labor output cost.

[0010] Optionally, the support member includes a first slide rail, a vertical frame is slidably provided on the first slide rail, and a support plate is provided on the vertical frame. The two vertical frames can slide in a direction away from or close to each other on the first slide rail, and the two vertical frames approach each other until the two support plates clamp the tower.

[0011] By adopting the above technical solution, when the tower needs to be zinc sprayed, the vertical frame is driven to slide on the first slide rail, and the vertical frame drives the two support plates to slide in the direction of approaching each other, thereby clamping the tower, and the two support plates are respectively abutted against the two ends of the tower, thereby fixing the tower; when the zinc spraying operation of the tower is completed and the zinc layer on the outer surface of the tower is dry, the two vertical frames are driven to slide in the direction of moving away from each other, thereby releasing the fixation of the tower; the cooperation of the various components in the above process facilitates the connection and separation of the support and the tower.

[0012] Optionally, a positioning pin is provided on the support plate, and the positioning pin is used to be inserted into a screw hole on the tower flange surface.

[0013] By adopting the above technical solution, when the two support plates move in the direction of approaching each other until the tower is clamped, the support plates abut against the end faces of the tower, and the positioning pins are inserted into the screw holes on the flange surface of the tower, thereby improving the tightness of the connection between the support plates and the tower, and further improving the stability during the zinc spraying operation.

[0014] Optionally, an auxiliary frame for supporting the tower is slidably provided on the first slide rail, and the auxiliary frame can move in a direction away from or close to the tower.

[0015] By adopting the above technical solution, before the tower is sprayed with zinc, the tower can be placed on the auxiliary frame first, and then the two support plates are driven to slide until the tower is tightly fixed, and then the auxiliary frame is driven to move away from the tower until it is away from the tower, and then the zinc spraying operation can be carried out. The setting of the auxiliary frame can facilitate the support plate to fix the tower.

[0016] Optionally, the auxiliary frame includes a positioning frame slidingly connected to the first slide rail, and a roller is rotatably connected to the positioning frame, and the positioning frame can move in a direction away from or close to the tower; the positioning pin includes a fixed rod arranged on the support plate, and a movable rod is coaxially slidably connected to the fixed rod, and a push spring is arranged between the movable rod and the fixed rod.

[0017] When the support plate is moved in a direction close to the tower, the fixed rod and the movable rod fail to be inserted into the screw holes of the tower flange surface at once, and the movable rod is forced to slide into the movable rod. At this time, the pushing spring is in a compressed state, and then the roller is driven to rotate, further driving the tower to rotate. When the tower is transmitted to the screw holes of the movable rod and the tower flange surface are aligned, the pushing spring pushes the movable rod to slide in a direction away from the fixed rod, thereby driving the movable rod to slide into the screw holes of the tower flange surface. At this time, the tower cannot continue to rotate, the roller stops rotating, and then the supporting plate is driven to continue sliding until it contacts the end face of the tower, thereby fixing the tower. The cooperation of various components in the above process makes it convenient for the positioning pin to be inserted into the screw holes of the tower flange surface, without the need to position the tower, further improving the convenience of the device.

[0018] Optionally, the linear guide rail includes two fixed ends, each of the fixed ends is fixedly connected to a support member, a plurality of splicing units are detachably connected between the two fixed ends, and the power unit can slide on the fixed ends and the splicing units.

[0019] By adopting the above technical solution, the linear guide rail is composed of two fixed ends and multiple splicing units. When the length of the tower to be processed changes, the number of splicing units can be changed to adapt to the change in tower length.

[0020] Optionally, the splicing unit includes a first splicing segment and a second splicing segment, and the first splicing segment is detachably connected to the second splicing segment of another splicing unit; an adjustment segment is slidably provided between the first splicing segment and the second splicing segment, and the adjustment segment can slide into the first splicing segment and / or the second splicing segment, and the power unit can slide on the first splicing segment, the second splicing segment and the adjustment segment.

[0021] By adopting the above technical solution, the adjustment section can be slid by pulling the first splicing section and the second splicing section, so that the overall length of the splicing unit can be changed and adjusted, further improving the applicability of the linear guide rail.

[0022] Optionally, the power unit includes a fixed block, the annular guide rail is arranged on the fixed block, and a plurality of rolling wheels are provided on the fixed block, and the radial distance between the two rolling wheels farthest apart is greater than the length of the adjustment section; the first splicing section, the second splicing section and the adjustment section are all provided with a sliding groove, a limiting plate is fixed on the sliding groove, and a limiting block is provided on the fixed block to fit the limiting plate.

[0023] By adopting the above technical solution, the rolling wheel can slide in the slide groove, and when the rolling wheel is located in the first splicing section and / or the second splicing section, the limit plate is fitted with the limit block, so that the movement direction of the fixed block is restricted; when the adjusting section slides into the first splicing section and the second splicing section until the first splicing section and the second splicing section are abutted, the first splicing section and the second splicing section are docked and are in the same plane. Since the adjusting section can slide into the first splicing section and the second splicing section, when the adjusting section slides out, there is a height difference between the adjusting section and the first splicing section, and between the adjusting section and the second splicing section. Since the radial distance between the two rolling wheels farthest apart on the fixed block is greater than the length of the adjusting section, when one rolling wheel rolls on the first splicing section, the other rolling wheel on the fixed block will roll on the second splicing section, and the fixed block moves smoothly without tilting, thereby eliminating the influence of the height difference on the movement of the fixed block.

[0024] Optionally, a plurality of mutually parallel linear guide rails are arranged between the two support members, the annular guide rail includes a plurality of connection groups, each connection group includes two connection sections and a fixed section, the two connection sections are respectively fixed at the two ends of the fixed section, the two connection sections are respectively detachably connected to different power parts, and the zinc spraying part is arranged on the fixed section.

[0025] By adopting the above technical solution, through the cooperation of multiple linear guide rails and corresponding power units, the stability of the annular guide rail during overall movement can be improved, and the stability of the zinc spraying parts during operation can be further improved; since the connecting section of the annular guide rail can be detachably connected to the corresponding power unit, the zinc spraying range of the device can be controlled by controlling the connection between the connecting section and the power unit, so that in addition to performing overall zinc spraying on the tower, the device can also perform local zinc supplementation work.

[0026] Optionally, a first bidirectional screw rod is rotatably connected to the power unit, and the two connecting sections are respectively fixedly connected to two screw nuts of the first bidirectional screw rod.

[0027] By adopting the above technical solution, by driving the bidirectional screw to rotate, the corresponding two connecting sections on a power unit can be driven to move in the direction of moving away from or approaching each other, thereby expanding or reducing the zinc spraying range to adapt to the zinc spraying work of towers with different diameter specifications.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The coordination of various components in this device enables the zinc spraying operation of the tower to be completed in one go, thereby improving the efficiency of the zinc spraying operation and ensuring a consistent thickness of the zinc layer after spraying. At the same time, the zinc spraying operation is automated, further reducing labor output costs.

[0030] 2. Through the cooperation of multiple linear guide rails and corresponding power units, the stability of the annular guide rail during overall movement can be improved, and the stability of the zinc spraying parts during operation can be further improved; since the connecting section of the annular guide rail can be detachably connected to the corresponding power unit, the zinc spraying range of the device can be controlled by controlling the connection between the connecting section and the power unit, so that in addition to performing overall zinc spraying on the tower, the device can also perform local zinc supplementation work.

The two vertical frames 102 can slide in a direction away from or approaching each other on the first slide rail 101, and the two vertical frames 102 approach each other until the two support plates 103 clamp the tower 15; when it is necessary to spray zinc on the tower 15, the vertical frame 102 is driven to slide on the slide rail, and the vertical frame 102 drives the two support plates 103 to slide in a direction approaching each other, thereby clamping the tower 15, and the two support plates 103 respectively abut against the two end portions of the tower 15, thereby fixing the tower 15; when the zinc spraying operation of the tower 15 is completed and the zinc layer on the outer surface of the tower 15 is dried, the two vertical frames 102 are driven to slide in a direction away from each other, thereby releasing the fixation of the tower 15.

[0042] Reference Figure 3 and Figure 4The support disk 103 is rotatably connected to the second bidirectional screw rod 7, and the second bidirectional screw rod 7 is parallel to the radial direction of the support disk 103. A motor is installed on the support disk 103, and the output shaft of the motor is coaxially fixedly connected to the second bidirectional screw rod 7. A fixed rod 601 is fixed to each of the two screw nuts of the second bidirectional screw rod 7. A movable rod 602 is coaxially slidably connected in the fixed rod 601. A push spring 603 is provided between the movable rod 602 and the fixed rod 601.

[0043] Reference Figure 1 and Figure 2 A second slide rail 16 is vertically arranged on the first slide rail 101, and a positioning frame 801 is slidably arranged on the second slide rail 16. The positioning frame 801 is rotatably connected to a roller 802 for supporting the tower 15, and the positioning frame 801 can move in a direction away from or close to the tower 15.

[0044] Before zinc spraying operation is performed on the tower 15, the tower 15 can be placed on the roller 802 first, and then the support plate 103 is driven to slide until the fixed rod 601 and the movable rod 602 are inserted into the screw holes on the flange surface of the tower 15, and the support plate 103 slides until the end face of the tower 15 is tightly pressed; if the support plate 103 slides in the direction close to the tower 15, the fixed rod 601 and the movable rod 602 fail to be inserted into the screw holes on the flange surface of the tower 15 at one time, the movable rod 602 and the end face of the tower 15 are pressed against each other, and the movable rod 602 is forced to slide into the movable rod 602. At this time, the push spring 603 is in a compressed state, and then the roller 802 is driven to rotate, which further drives the tower 15 to rotate, and the tower 15 rotates When the movable rod 602 is moved to be aligned with the screw hole on the flange surface of the tower 15, the push spring 603 pushes the movable rod 602 to slide in the direction away from the fixed rod 601, thereby driving the movable rod 602 to slide into the screw hole on the flange surface of the tower 15. At this time, the tower 15 cannot continue to rotate, and the roller 802 stops rotating, and then drives the support plate 103 to continue to slide until it abuts against the end face of the tower 15, thereby fixing the tower 15; thereby facilitating the insertion of the positioning pin 6 into the screw hole on the flange surface of the tower 15, and there is no need to position the tower 15, further improving the convenience of the device. When performing zinc spraying operation, drive the positioning frame 801 to move in the direction away from the tower 15 until it is away from the tower 15.

Since the radial distance between the two rolling wheels 302 on the fixed block 301 that are farthest apart is greater than the length of the adjustment section 2023, when one rolling wheel 302 rolls on the first splicing section 2021, the other rolling wheel 302 on the fixed block 301 will roll on the second splicing section 2022, and the fixed block 301 moves smoothly without tilting, thereby eliminating the influence of the height difference on the movement of the fixed block 301.
