Description

Technical Field

[0001] The invention relates to the technical field of tower main column manufacturing, in particular to a tower main column flange riveting tool. Background Art

[0002] The multi-section main columns of a prestressed wind tower are composed of steel pipes and flanges, which can be welded together after being butted together. The steel pipes of the tower main columns are relatively long and large in diameter, so cranes are used to transport the pipes during factory assembly. The existing assembly process involves creating through-holes in the riveting positions according to the drawing dimensions. Bolts are inserted through the through-holes and the flange holes to secure the flange to the riveting positions. The riveting positions are vertically arranged, so the flange axis is horizontal. Two cranes are used to lift the steel pipes at both ends, aligning them with the flanges. After butt-jointing, the two flanges can be connected through welding, riveting, and other methods. Welding is generally used, requiring the steel pipes and flanges to remain relatively stationary after being butt-jointed. This occupies two cranes for a long time, increasing production costs and impacting the crane's use during other production processes. Furthermore, the cranes use ropes to lift the steel pipes on both sides, leaving them suspended in the air. This creates poor stability and hinders the stable butt-jointing of the pipes and flanges.

[0003] In the prior art, two cranes are required to connect the steel pipes and flanges, and the problem of high production cost needs to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a tower main column flange riveting tool to address the above-mentioned technical deficiencies, which solves the problem in the prior art that two cranes are required to connect steel pipes and flanges, resulting in high production costs.

[0005] The technical solution adopted by the present invention is to provide a tower main column flange riveting tool for assisting a crane in connecting a steel pipe and a flange, comprising a base and a riveting position, on which the flange is fixed by bolts, and characterized by further comprising: A slide is slidably arranged on the base, and the riveted tire position is swingably arranged on the slide. After the riveted tire position swings, it is used to drive the flange to rotate to an inclined state; The tailstock is movably arranged relative to the base, and is used to support the end of the steel pipe away from the riveting position. The crane is used to lift the end of the steel pipe close to the riveting position, and the inclined steel pipe is docked with the inclined flange.

[0006] To further optimize the technical solution, the lower part of the riveted tire position is rotatably arranged on the slide.

[0007] Further optimization of this technical solution also includes: A hydraulic cylinder assembly is swingably arranged on the slide, and a movable end of the hydraulic cylinder assembly is hingedly arranged on the upper part of the riveted tire position for driving the riveted tire position to swing.

[0008] Further optimization of this technical solution also includes: A lead screw is rotatably arranged on the base and is threadedly connected to the slide seat to drive the slide seat to slide.

[0009] Further optimization of this technical solution also includes: The limit seat has a base plate and a baffle, the baffle is located above the base plate, the base plate is used to support the end of the steel pipe, the baffle is used to abut against the end face of the steel pipe, the limit seat is rotatably set on the tail seat, and the tail seat supports one end of the steel pipe through the limit seat.

[0010] To further optimize this technical solution, the upper end of the base is provided with a groove, and the end of the steel pipe is located in the groove.

[0011] Further optimization of this technical solution also includes: The walking wheels are provided in a plurality, wherein the plurality of the walking wheels are distributed at the bottom end of the tailstock and are rotatably arranged.

[0012] Further optimizing this technical solution, the tailstock lifting arrangement further includes: There are several telescopic legs, which are distributed on the tailstock. The moving ends of the telescopic legs are used to abut against the ground, and the telescopic legs are used to drive the tailstock to rise and fall.

[0013] Further optimization of this technical solution also includes: There are at least two clamping seats, both of which are arranged on the riveted position and are used to support the lower part of the circumferential surface of the flange.

[0014] The beneficial effects of the present invention are: 1. One end of the steel pipe can be lifted by a crane to tilt the pipe. After the riveting position is tilted, the flange can be tilted. In this tilted state, the flange and steel pipe can be docked, using only one crane. During docking in the tilted state, the flange exerts pressure on the steel pipe, and the overall tooling is approximately triangular during docking, which helps to improve the docking stability of the flange and steel pipe.

[0015] 2. The tailstock is movable relative to the base, which is convenient for moving after the steel pipe is lifted by the crane, and for adjusting the connection between the steel pipe and the flange. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0019] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0020] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] like Figure 1-6As shown, the tower main column flange riveting tool is used to assist a crane in docking the steel pipe 1 and the flange 2, including a base 3 and a riveting position 5, and the flange 2 is fixed to the riveting position 5 by bolts, and also includes: a slide 4, which is slidably set on the base 3, and the riveting position 5 is swingably set on the slide 4. After the riveting position 5 swings, it is used to drive the flange 2 to an inclined state; a tail stock 6, which is movably set relative to the base 3, and the tail stock 6 is used to support one end of the steel pipe 1 away from the riveting position 5. The crane is used to hoist the end of the steel pipe 1 close to the riveting position 5, and the inclined steel pipe 1 is docked with the inclined flange 2.

[0022] When in use, the riveted tire position 5 swings to an inclined state and has at least two positions, such as Figure 4 As shown, one position is the flange mounting position. At this time, the side of the riveted tire 5 in the inclined state fixedly fitted with the flange 2 is inclined upward, and is used to fix the flange 2 on the riveted tire 5 with bolts. The riveted tire 5 in the flange mounting position can provide a certain upward supporting force for the flange 2, so that the flange 2 is placed on the riveted tire 5 and then adjusted to its position. After the flange 2 is aligned with the through hole on the riveted tire 5, it is tightened with bolts, which makes the fixing and installation of the flange 2 more convenient. Figure 5 As shown, the other position is the steel pipe flange docking position. At this time, the flange 2 is fixed on the riveted position 5 in an inclined state, and the side of the flange 2 docking with the steel pipe 1 is tilted downward.

[0023] The steps for use are as follows: rotate the riveting position 5 to the flange installation position, place the flange 2 and adjust its alignment, and bolt the flange 2 to the riveting position 5 to complete the preparation of the flange 2. Simultaneously, a crane can be used to lift the end of the steel pipe 1 away from the riveting position 5 (the tail of the steel pipe 1) using a lifting rope and place it on the tailstock 6. The crane then detaches from the tail of the steel pipe 1 and moves to the end of the steel pipe 1 near the riveting position 5 (the head of the steel pipe 1) and lifts the head of the steel pipe 1, tilting it upward, completing the preparation of the steel pipe 1. Then, in coordination with the movement of the crane, the tailstock 6 can be moved closer to the base 3, and the riveting position 5 can be rotated to the steel pipe flange docking position to achieve docking between the steel pipe 1 and the flange 2. The slide 4 can be moved on the base 3 for fine adjustment. When assembling tower main columns of the same batch or model, the steel pipes 1 and flanges 2 of the main columns are of uniform specifications. The various parameters for docking the flanges 2 and steel pipes 1 can be determined, such as the position and tilt angle of the riveting position 5, the tilt angle or end height of the steel pipe 1, and the spacing between the tailstock 6 and the base 3. Therefore, the process can be executed according to the preset parameters, achieving a relatively fast docking of the flanges 2 and steel pipes 1. Even after replacing different flanges 2 and steel pipes 1, the process can be operated more quickly and stably according to the preset parameters.

[0024] like Figure 3As shown, after the flange 2 and the steel pipe 1 are butted together, they are tilted as a whole. The flange 2 exerts pressure on the steel pipe 1, improving the butt joint stability and end-face fit between the two. The tail of the steel pipe 1 can be considered to be in a stable state on the ground. The riveted joint 5, the ground, the flange 2, and the steel pipe 1 can be considered to be in a relatively stable triangle-like state, which is conducive to stable welding after butt joint and improves welding quality.

[0025] Furthermore, the lower portion of the riveted tire position 5 is rotatably arranged on the slide 4. The system further comprises: a hydraulic cylinder assembly 402, which is swingably arranged on the slide 4, and a movable end of the hydraulic cylinder assembly 402 is hingedly arranged on the upper portion of the riveted tire position 5 for driving the riveted tire position 5 to swing.

[0026] During use, the lower portion of the riveting station 5 can be rotated on the slide 4, and the hydraulic cylinder assembly 402 can be used to drive the swing of the riveting station 5. A vertical frame 401 can be mounted on the slide 4, and the fixed end of the hydraulic cylinder assembly 402 is rotatably connected to the upper portion of the vertical frame 401. The inclination angle of the riveting station 5 can be controlled by driving the hydraulic cylinder assembly 402. Alternatively, an angle ruler, an existing automatic angle measuring device, or a travel switch can be installed on the side of the slide 4 to assist in determining the angular position of the riveting station 5, thereby improving the level of automation and angle adjustment accuracy, and better achieving the connection between the flange 2 and the steel pipe 1.

[0027] Furthermore, it also includes: a screw 301 rotatably arranged on the base 3 , and the screw 301 is threadedly connected to the slide 4 for driving the slide 4 to slide.

[0028] During use, the slide 4 is driven by the lead screw 301, assisting in fine-tuning the flange 2 against the steel pipe 1. A travel switch for the slide 4 can be set according to preset parameters to ensure the precision and automation of the slide 4's position adjustment. The end of the lead screw 301 can be provided with a handle for manual rotation, or it can be driven by a motor, etc. The slide 4 can also be driven by an existing controllable linear drive mechanism, a conventional technique.

[0029] The base 3 may be provided with a dovetail groove structure, and the lower portion of the slide 4 may have a sliding connection structure adapted to the dovetail groove, which allows for stable sliding and can maintain the stability of the riveted tire 5 in the tilted state. The stability of the riveted tire 5 when it is in the butt joint position of the steel pipe flange can also be ensured by adding a counterweight.

[0030] Furthermore, the present invention further comprises a limit seat 7 having a bottom plate 701 and a baffle 702, wherein the baffle 702 is located above the bottom plate 701, the bottom plate 701 is used to support the end of the steel pipe 1, and the baffle 702 is used to abut against the end face of the steel pipe 1. The limit seat 7 is rotatably mounted on the tailstock 6, and the tailstock 6 supports one end of the steel pipe 1 through the limit seat 7. The upper end of the base 3 has a groove 7011, and the end of the steel pipe 1 is located in the groove 7011.

[0031] When in use, the limit seat 7 supports the tail of the steel pipe 1, and the limit seat 7 rotates on the tailstock 6. When the head of the steel pipe 1 is lifted to tilt the steel pipe 1, the limit seat 7 adaptively follows the rotation to reduce the wear of the tail of the steel pipe 1. The limit seat 7 has a larger contact area with the tail of the steel pipe 1 through the bottom plate 701 and the baffle 702, which has better limiting stability for the tail of the steel pipe 1, reduces the shaking or sliding of the steel pipe 1, and is more stable relative to the flange 2. When the tailstock 6 moves, in order to keep it facing the base 3, that is, to keep the steel pipe 1 and the flange 2 facing each other, a slide rail or the like can be set on the ground to limit the moving direction of the tailstock 6.

[0032] The base plate 701 and baffle 702 form a roughly "L" shape, providing stable support and positioning for the end of the steel pipe 1. The groove 7011 on the base plate 701 can be curved, with a low position located in the middle, directly opposite the center of the flange 2. This allows the end of the steel pipe 1 to remain relatively stable at its low potential energy position. Even if the diameter of the steel pipe 1 changes or the end of the steel pipe 1 is connected to the flange 2, the position of the groove 7011 can be adjusted accordingly.

[0033] Furthermore, the machine further comprises: a plurality of running wheels 601, which are distributed at the bottom of the tailstock 6 and are rotatably arranged. The tailstock 6 is arranged to be raised and lowered; and a plurality of telescopic legs 602, which are distributed on the tailstock 6 and have their movable ends abutting against the ground. The telescopic legs 602 are used to drive the tailstock 6 to rise and fall.

[0034] When in use, a plurality of running wheels 601 are distributed on the tailstock 6, which can make movement easier.

[0035] Telescopic legs 602 can be used to raise and lower tailstock 6, facilitating the preset parameters for docking steel pipes 1 of varying lengths and diameters. This provides a wider range of applications, facilitates the production of main columns of varying specifications, and facilitates adjustment. For example, if the angle of the riveted joint 5 remains unchanged, shortening the steel pipe 1 requires raising the tail end of the pipe 1 to match the tilt angle. In this case, telescopic legs 602 need to be extended to raise tailstock 6. For example, if the diameter of the steel pipe 1 increases while the central axis tilt remains unchanged, the tailstock 6 needs to be lowered.

[0036] The telescopic legs 602 can also be used in conjunction with the running wheels 601. When the tailstock 6 needs to be moved, the telescopic legs 602 are retracted, the moving end leaves the ground, and the running wheels 601 touch the ground. When the tailstock 6 is moved to the desired position, the telescopic legs 602 are lowered, the moving end touches the ground, and the running wheels 601 are raised. At the same time, the tailstock 6 is fixed at the height specified in the preset parameters. The telescopic legs 602 can be hydraulic cylinders, etc., and the moving end can be equipped with anti-skid plates. Four telescopic legs 602 can be provided, distributed at the four corners of the tailstock 6.

[0037] Furthermore, it also includes: a clamping seat 8, of which there are at least two, and the two clamping seats 8 are both arranged on the riveting position 5, for supporting the lower part of the circumferential surface of the flange 2.

[0038] During use, the clamping seat 8 can assist in positioning when fixing the flange 2 on the riveting position 5. When fixing the flange 2, the riveting position 5 is in the flange installation position. The clamping seat 8 can be pre-installed on the riveting position 5 according to the size. With the help of a handling tool, the flange 2 is placed at the center of the riveting position 5. The lower part of the flange 2 abuts against the two clamping seats 8. The clamping seats 8 play a supporting and positioning role. The flange 2 will not slip before it is fixed. No other tools are needed to achieve the initial positioning of the flange 2, and then it can be fixed with bolts. Positioning and fixing are more convenient and quick.

[0039] The riveted mounting 5 has a through-hole, to which a retainer 8 is secured by bolts. The retainer 8 is adapted to fit the flange 2, abutting against the outer periphery of the flange 2 for positioning. Of course, retainer 8 can also be provided with a sliding structure, such as a threaded connection for movement, to facilitate movement and adjustment relative to the outer periphery of the flange 2, aligning the flange 2 with the through-hole. At least two retainers 8 are provided, distributed on both sides of the lower portion of the flange 2, to achieve centering and support.
