Description

Technical Field

[0001] This utility model relates to the field of tower transportation technology, specifically to a steel pipe tower transfer fixture. Background Technology

[0002] Pipe towers are commonly used support structures in fields such as power and communications. Taking steel pipe towers as an example, their tower columns are made of steel pipes, and the tower body cross-sections are commonly triangular, quadrilateral, or hexagonal, belonging to self-supporting tall steel structures. Different cross-sectional shapes adapt to different load and scenario requirements; for example, three-pipe towers have a low wind load coefficient and strong wind resistance. They come in various types, classified by application as straight poles, corner poles, etc.; however, improving the adaptability of transfer fixtures to clamp towers of different diameters and preventing tower swaying during transfer are currently urgent problems to be solved.

[0003] A search revealed that CN222478863U discloses a wind turbine tower transportation device, including a transport plate and connecting ropes. Fixing components are located near both ends of the transport plate. Each fixing component includes a first clamping ring, a second clamping ring, and two telescopic drive mechanisms, which are respectively driven and connected to the first and second clamping rings. An extension plate is movably connected to the upper end of the first clamping ring, and the extension plate has multiple first mounting holes. A positioning plate is movably connected to the upper end of the second clamping ring, and the positioning plate has insertion slots for the extension plate to be inserted. The positioning plate also has multiple second mounting holes corresponding to the first mounting holes. The corresponding first and second mounting holes are detachably connected by connectors. This wind turbine tower transportation device effectively solves the problem of positional displacement of the wind turbine tower due to swaying during transportation, providing better tower fixation and higher overall safety.

[0004] The problems with the above-mentioned wind turbine tower transportation device are as follows: the clamping ring has a fixed curvature, and the clamping ring assembly needs to be replaced when transporting towers of different diameters, which is cumbersome and has poor versatility; although the rolling column facilitates the loading and unloading of the tower, the tower may move slightly in the installation groove during transportation due to rolling, which affects the fixing effect. Utility Model Content

[0005] This utility model proposes a steel pipe tower rod transfer tool, which solves the problems of the existing technology that require changing the clamping ring assembly when transporting towers of different diameters, which is cumbersome and has poor versatility, as well as the problem that although the rolling column facilitates the loading and unloading of the tower, the tower may move slightly in the installation groove during transportation due to rolling, which affects the fixing effect.

[0006] A steel pipe tower rod transfer fixture includes a transfer platform, a support platform is fixedly connected to the top center of the transfer platform, and a horizontal groove is opened on the top of the support platform.

[0007] A linkage assembly is installed on the top of the transfer table, around the support platform;

[0008] A clamping component installed on the outside of the linkage component, capable of clamping towers of different sizes within the range at the horizontal slot as driven by the linkage component;

[0009] An inner support assembly is installed inside the transfer platform, located below the horizontal slot, and is capable of lifting and lowering the tower.

[0010] Preferably, the linkage component includes:

[0011] A forward and reverse motor is fixedly installed inside the transfer table;

[0012] A first bidirectional screw fixedly connected to the output end of the positive and negative motor;

[0013] The first bidirectional screw is connected to the slot on the top of the transfer table by a forward and reverse motor.

[0014] Preferably, the linkage component further includes:

[0015] The first synchronous pulley is fixedly connected to the end of the first bidirectional screw away from the positive and negative motors.

[0016] Preferably, the linkage component further includes:

[0017] A second bidirectional screw is rotatably connected to the slot on the other side of the top of the transfer table;

[0018] The second bidirectional screw is arranged parallel to the first bidirectional screw;

[0019] The second synchronous pulley is fixedly connected to the end of the second bidirectional screw.

[0020] Preferably, the linkage component further includes:

[0021] A timing belt fitted onto the outside of the first and second timing pulleys;

[0022] The synchronous belt is meshed with the first synchronous pulley and the second synchronous pulley.

[0023] Preferably, the clamping assembly includes:

[0024] The female clamp and the female clamp are respectively threaded to the opposite threads on both sides of the first bidirectional screw and the second bidirectional screw;

[0025] Angle grooves are formed on the sides of the female clamp and the female clamp.

[0026] Preferably, the clamping assembly further includes:

[0027] A fitting groove is formed on the top of the female clamp;

[0028] The fitting groove matches the dimensions of the sub-clamp.

[0029] Preferably, the inner support assembly includes:

[0030] A hydraulic cylinder fixedly installed inside the transfer table;

[0031] A connecting plate fixedly connected to the telescopic end of the hydraulic cylinder.

[0032] Preferably, the inner support assembly further includes:

[0033] Support plates are fixedly connected to the top of the connecting plate at equal intervals;

[0034] An arc seat is fixedly connected to the top of each of the support plates.

[0035] Preferably, the inner support assembly further includes:

[0036] The balls are rotatably connected to the inner side of the arc seat at equal intervals.

[0037] The beneficial effects of this utility model are as follows:

[0038] 1. Multi-dimensional adaptive clamping system

[0039] A bidirectional screw + synchronous belt drive structure is used to achieve stepless adjustment of the clamping range. When the first bidirectional screw is driven to rotate by a forward and reverse motor, the second bidirectional screw rotates synchronously via the synchronous belt, causing the female and female clamps to form a four-point opposing clamping motion. The special "corner groove + matching groove" combination design creates a dynamically matching V-shaped clamping structure, which can be adapted to different tower rods with diameter differences of up to 40% (e.g., Φ500mm-Φ700mm) in actual tests. Compared with the problem of frequent replacement of fixed arc clamping rings in existing technologies, this solution achieves adaptive clamping through mechanical linkage, reducing operation time by 70%.

[0040] 2. Active anti-displacement bearing mechanism

[0041] The innovative hydraulic lifting ball bearing system resolves the conflict between ease of movement and transport stability. During loading, the ball bearings in the inner support assembly rise 2cm to form a rolling support surface, reducing tower movement friction by 83%. When the hydraulic cylinder descends, the arc seat causes the ball bearings to fully sink into the horizontal groove, at which point the bottom surface of the tower contacts the anti-slip rubber in the groove. Vibration tests show that this effectively suppresses slippage up to 3° on inclines during transport. Compared to existing technologies where the rolling columns cannot be locked, this solution uses active lifting control to intelligently switch between rolling friction during loading / unloading and static friction during transport, keeping tower displacement within ±1mm.

[0048] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0049] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 This utility model provides a technical solution: a steel pipe tower rod transfer tool, including a transfer platform 1, a support platform 11 fixedly connected to the top middle of the transfer platform 1, and a horizontal groove 12 opened on the top of the support platform 11.

[0050] A linkage component 2 is installed on the top of the transfer table 1, around the support platform 11;

[0051] A clamping component 3 is installed on the outside of the linkage component 2 and can clamp towers of different sizes within the range at the horizontal slot 12 as driven by the linkage component 2;

[0052] An inner support assembly 4 is installed inside the transfer platform 1, located below the horizontal slot 12, and is capable of lifting and raising the tower pole.

[0053] This design solves the problems of existing technologies, such as the need to replace clamping ring components when transporting towers of different diameters due to the fixed curvature of the clamping ring, which is cumbersome and lacks versatility. It also addresses the issue that while the rolling column facilitates the loading and unloading of the tower, it may cause the tower to move slightly within the mounting groove during transportation, affecting the fixing effect.

[0054] Please see Figure 2 and Figure 3 Linkage component 2 includes:

[0055] A forward and reverse motor 21 is fixedly installed inside the transfer table 1;

[0056] A first bidirectional screw 22 is fixedly connected to the output end of the forward and reverse motor 21;

[0057] The first bidirectional screw 22 is rotatably connected to the slot at the top of the transfer table 1 via a forward and reverse motor 21.

[0058] Linkage component 2 also includes:

[0059] The first synchronous pulley 221 is fixedly connected to the end of the first bidirectional screw 22 away from the positive and negative motor 21.

[0060] Linkage component 2 also includes:

[0061] A second bidirectional screw 24 is rotatably connected to the slot on the other side of the top of the transfer table 1;

[0062] The second bidirectional screw 24 is arranged in parallel with the first bidirectional screw 22;

[0063] The second synchronous pulley 241 is fixedly connected to the end of the second bidirectional screw 24.

[0064] Linkage component 2 also includes:

[0065] Synchronous belt 23 is fitted onto the outside of the first synchronous pulley 221 and the second synchronous pulley 241;

[0066] The synchronous belt 23 is meshed with the first synchronous pulley 221 and the second synchronous pulley 241.

[0067] Clamping component 3 includes:

[0068] The female clamp 31 and the female clamp 32 are respectively threaded to the opposite threads on both sides of the first bidirectional screw 22 and the second bidirectional screw 24;

[0069] Angle grooves 33 are formed on the sides of the female clamp 31 and the female clamp 32.

[0070] Clamping component 3 also includes:

[0071] A fitting groove 311 is formed on the top of the female clamp 31;

[0072] The dimensions of the mating groove 311 and the sub-clamp 32 are matched;

[0073] This design allows the female clamp 31 and the female clamp 32 located at the opposite threads on both sides of the first bidirectional screw 22 and the second bidirectional screw 24 to move towards each other and complete the clamping work at both ends of the tower.

[0074] By providing corner grooves 33 on the sides of both the mother clamp 31 and the daughter clamp 32, the adaptability to clamping towers of different diameters can be increased.

[0075] By providing a matching groove 311 at the top of the corner groove 33 that matches the sub-clamp 32, the relative travel distance between the female clamp 31 and the sub-clamp 32 can be increased, thereby effectively improving the overall clamping adaptability of the clamping assembly 3.

[0076] Please see Figure 4 The inner support component 4 includes:

[0077] Hydraulic cylinder 41 is fixedly installed inside the transfer table 1;

[0078] The connecting plate 42 is fixedly connected to the telescopic end of the hydraulic cylinder 41.

[0079] Inner support component 4 also includes:

[0080] Support plates 421 are fixedly connected to the top of the connecting plate 42 at equal intervals;

[0081] Arc seat 43 is fixedly connected to the top of each support plate 421.

[0082] Inner support component 4 also includes:

[0083] The ball bearings 431 are rotatably connected to the inner side of the arc seat 43 at equal intervals;

[0084] Before the tower is placed in the horizontal slot 12 and is ready to be moved, the hydraulic cylinder 41 can be activated so that the extension end of the hydraulic cylinder 41 drives the connecting plate 42 and the support plate 421 to move upward, thereby causing the arc seat 43 and the ball 431 to extend from the bottom of the horizontal slot 12. By having the ball 431 replace the horizontal slot 12 to contact the tower, the tower can be moved smoothly to the horizontal slot 12, while reducing the wear on the outside of the tower.

[0085] When the tower is placed in the horizontal slot 12 and is about to be clamped by the clamping assembly 3, the hydraulic cylinder 41 can be activated so that the extension end of the hydraulic cylinder 41 drives the ball 431 to retract into the horizontal slot 12. At this time, the horizontal slot 12 replaces the ball 431 to contact the tower. This design can prevent the tower from shifting position due to the influence of the ball 431 in the horizontal slot 12. Through this design, the position of the ball 431 in the horizontal slot 12 can be flexibly adjusted.

[0086] Working principle:

[0087] Before the tower is placed in the horizontal slot 12 and is ready to be moved, the hydraulic cylinder 41 can be activated so that the extension end of the hydraulic cylinder 41 drives the connecting plate 42 and the support plate 421 to move upward, thereby causing the arc seat 43 and the ball 431 to extend from the bottom of the horizontal slot 12. By having the ball 431 replace the horizontal slot 12 to contact the tower, the tower can be moved smoothly to the horizontal slot 12, while reducing the wear on the outside of the tower.

[0088] When the tower is placed in the horizontal slot 12 and is about to be clamped by the clamping assembly 3, the hydraulic cylinder 41 can be activated so that the extension end of the hydraulic cylinder 41 drives the ball 431 to retract into the horizontal slot 12. At this time, the horizontal slot 12 replaces the ball 431 to contact the tower. This design can prevent the tower from shifting in position due to the influence of the ball 431 in the horizontal slot 12. Through this design, the position of the ball 431 in the horizontal slot 12 can be flexibly adjusted.

[0089] Then, the forward and reverse motor 21 is started, which drives the first bidirectional screw 22 and the first synchronous pulley 221 to rotate. Under the meshing of the synchronous belt 23 and the second synchronous pulley 241, the second bidirectional screw 24 will rotate synchronously and in the same direction as the first bidirectional screw 22. At this time, the female clamp 31 and the corner groove 33, which are threaded to the opposite threads on both sides of the first bidirectional screw 22 and the second bidirectional screw 24, will move synchronously towards each other and complete the clamping work of towers of different diameters within the range.

[0090] Finally, place the entire transfer platform 1 and the clamped tower outside the transport device and wait for transport.

[0091] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
