Description

Technical Field

[0001] This invention relates to the field of steel pipe tower transportation technology, and in particular to a steel pipe tower production and transportation device and its usage method. Background Technology

[0002] As a crucial supporting structure in power transmission lines, the manufacturing process of steel pipe towers involves the cutting, welding, painting, assembly, and transportation of numerous tubular components. Within the steel pipe tower production workshop, various pipe components need to be moved horizontally between different workstations to achieve efficient assembly line operations.

[0003] Traditional methods of transporting steel pipe tower components often involve ground carts, overhead cranes, or manual handling. These methods have shortcomings. Ground cart transport requires workshop floor space, which can easily interfere with other equipment or personnel. Furthermore, the components are prone to rolling or shifting during movement, resulting in poor positioning stability. While overhead cranes can achieve suspended transport, the lifting equipment is usually suspended at one or two points. Long-length components are prone to swaying during movement, and even end impacts can occur, causing the ends of the steel pipe tower components to shift during transport. This cannot guarantee the stability of the steel pipe tower components during transport. In addition, the grinding required for connecting the components needs to be done separately before transport, which increases the process time and labor costs, affecting the stability of the suspended transport of steel pipe tower components.

[0014] A method for producing and transporting a steel pipe tower, the method comprising the steel pipe tower production and transport apparatus as described above, specifically including the following steps: Step 1: By retracting the telescopic end of the first electric telescopic rod, the connecting rod can be pulled, causing multiple L-shaped rods to pull the limiting plate, so that the limiting plate can be in an open state with the bearing hook for placing and bearing the steel pipe tower component. Then, by extending the telescopic end of the first electric telescopic rod, the connecting block can push the connecting rod, so that multiple limiting plates can press down on the inner cavity of the bearing hook, so that the limiting plate can press down and lock the outer wall of the steel pipe tower component supported by the inner cavity of the bearing hook for positioning. Step 2: Secure the connecting strip to the middle of the pull rope using multiple Velcro assemblies, and wrap the pull rope located at the end of the steel pipe tower component around the outer wall of the steel pipe tower component, so that the outer wall of the connecting strip can fit and wrap around the outer wall of the steel pipe tower component. Driven by the second electric telescopic rod, the connecting strip is locked on the outer wall of the steel pipe tower component by pulling the rope, which is used to control the end position of the steel pipe tower component during movement. Step 3: When it is necessary to grind the burrs on the outer wall end of the steel pipe tower component, pull the rope so that the connecting strip wrapped around the outer wall of the steel pipe tower component can slide and rub against the outer wall of the steel pipe tower component, so that the burrs can be ground off by sandpaper.

[0015] The technical effects and advantages of this invention are as follows: (1) The present invention uses a combination of a bearing mechanism and a limiting mechanism. The curved structure at the bottom of the bearing hook, combined with a rotatable limiting plate, can wrap and press down on steel pipe tower parts of different diameters. Combined with the linkage mechanism driven by the first electric telescopic rod, multiple limiting plates can be pressed down and limited synchronously, so that the steel pipe tower parts are reliably pressed at multiple bearing points, preventing rolling or shaking during transportation and improving the stability of suspended transportation. (2) The present invention uses an auxiliary frame and a pull rope in combination. The second electric telescopic rod on the auxiliary frame drives the pull rope to wrap and lock the end of the steel pipe tower component. With the help of a high-strength wear-resistant rope, the free swing of the end of the long pipe component is controlled, which further improves the transportation safety and enhances the stability of the end of the steel pipe tower component during transportation. (3) The present invention uses a combination of pull rope and friction strip. The friction strip on the pull rope includes sandpaper and Velcro assembly. During transportation, the sandpaper can slide and rub against the outer wall of the pipe by pulling the pull rope to remove burrs. No additional process is required, which reduces the production cycle and labor cost. The sandpaper can be quickly replaced through the adhesive layer, which is convenient for maintenance. At the same time, when there is no need to polish, the sandpaper increases the connection stability between the pull rope and the steel pipe tower and reduces friction damage to the outer wall of the pull rope. (4) The present invention uses a combination of a clamp rod and a second base plate to achieve multi-position synchronous locking between adjacent bearing hooks through the sliding connection between the clamp rod and the second base plate, and the clamping assembly can quickly adjust the spacing between adjacent bearing mechanisms to adapt to the bearing requirements of steel pipe tower components of different lengths and improve the convenience of bearing operation of steel pipe tower components of different lengths.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides, for example Figures 1-8 The image shows a steel pipe tower production and transportation device.

[0020] Example 1: Includes a slide rail 100 and multiple pulleys 200 that slide on the slide rail 100, as well as a bearing mechanism 300, a limiting mechanism 400, and an auxiliary frame 500. The slide rail 100 can be fixed to the steel pipe tower production workshop by a hanger. The pulleys 200 can move along the track of the slide rail 100. The bearing mechanism 300 is installed at one end of the pulley 200 by a pin, so that the bearing mechanism 300 can follow the pulley 200 and move along the installation track of the slide rail 100. The multiple bearing mechanisms 300 are used for the horizontal bearing of the steel pipe tower components. The movement of the bearing mechanisms 300 facilitates the horizontal movement of the steel pipe tower components through the multiple bearing mechanisms 300. The limiting mechanism 400 is installed between the multiple bearing mechanisms 300. The limiting mechanism 400 is used to press the steel pipe tower components of different specifications by pushing the bottom of the bearing mechanism 300, so that the steel pipe tower components can be stabilized at the bottom of the bearing mechanism 300 through the limiting mechanism 400, thereby improving the stability of the production and transportation of steel pipe tower components. The bearing mechanism 300 includes a bearing hook 301, a limiting plate 302, and a connecting member. The top of the bearing hook 301 is rotatably inserted into the middle of the pulley 200 via a pin. The bottom of the bearing hook 301 has a curved structure, which facilitates the bearing of circular steel pipe structures. The bottom of the limiting plate 302 is rotatably connected to the bottom of the bearing hook 301 via a pin, and the limiting plate 302 and the bottom of the bearing hook 301 are coaxial arc-shaped plate structures. When the limiting plate 302 rotates away from the vertical plane of the bearing hook 301, it causes the bearing hook 301 to... The bottom has a small semi-circular structure, which facilitates the stable placement of the steel pipe tower components into the bottom cavity of the bearing hook 301. The limiting plate 302 presses down on the inner cavity of the bearing hook 301, so that the inner wall of the limiting plate 302 can press down on the steel pipe tower component, so that the steel pipe tower component can be fixed at multiple points, which can improve the stability of the steel pipe tower component suspended below the slide rail 100. The connector is installed between two adjacent bearing hooks 301. The connector is used for the synchronous movement of multiple limiting plates 302, and is used to assist in the positioning and bearing of steel pipe tower components of different specifications.

[0021] Specifically, the connector includes a first base plate 303, a locking rod 304, and a second base plate 305. The first base plate 303 is fixed to the bottom of one of the bearing hooks 301. Multiple locking rods 304 are horizontally and parallelly fixed to one end of the first base plate 303. The second base plate 305 is fixed to the bottom of another bearing hook 301. The second base plate 305 and the locking rod 304 are in opposite directions. The locking rod 304 is inserted into and confined in the middle of the second base plate 305. The locking rod 304 is composed of a round rod and multiple slots. The multiple slots are equidistantly opened at the bottom of the round rod. Through the slots, it is convenient to connect and limit the locking rod 304 with the second base plate 305, thereby improving the stability of parallel movement between two adjacent bearing hooks 301.

[0022] Additionally, the limiting mechanism 400 includes a connecting plate 401, a first electric telescopic rod 402, a connecting block 403, a connecting rod 404, and L-shaped rods 405. The connecting plate 401 is fixed to one side of the second base plate 305. The first electric telescopic rod 402 is rotatably connected to one end of the connecting plate 401 via a pin, allowing the first electric telescopic rod 402 to rotate freely at one end of the connecting plate 401. The connecting block 403 is fixed to the telescopic end of the first electric telescopic rod 402, and the first electric telescopic rod 402 is used to push the connecting block 403. The connecting rod 404 rotatably passes through the middle of the connecting block 403. Multiple L-shaped rods 405 are distributed... The connecting rod 404 is fixed to the outer wall of the adjacent limiting plate 302. The end of the connecting rod 404 is fixedly connected to the bottom of the adjacent L-shaped rod 405. The extension end of the first electric telescopic rod 402 drives the connecting rod 404 to push, so that the limiting plate 302 can rotate around the pin on the bottom bearing hook 301. The L-shaped rod 405 has an L-shaped structure. The first electric telescopic rod 402 is electrically connected to an external power source through an external controller. Driven by the controller, the extension end of the first electric telescopic rod 402 can extend and retract, so that the connecting rod 404 can move, so that the multiple L-shaped rods 405 can drive the adjacent fixed limiting plate 302 to rotate.

[0023] During use, the first electric telescopic rod 402 is reverse-driven, causing its telescopic end to retract. This allows the connecting block 403 to move the connecting rod 404. Furthermore, the L-shaped rod 405 is fixed to the limiting plate 302, enabling the limiting plate 302 to rotate stably around its bottom pin. This allows the limiting plate 302 to rotate in the opposite direction, facilitating the horizontal placement of the steel pipe tower component within the bearing hook 301. After the steel pipe tower component is stably placed, the first electric... The telescopic rod 402 is driven, and the telescopic end of the first electric telescopic rod 402 can be pushed, so that the connecting rod 404 can move upward, and the limiting plate 302 can rotate around the bottom pin as the axis toward the inner wall of the bearing hook 301. The inner wall of the limiting plate 302 can be stably placed on the outer wall of the steel pipe tower component, so that the steel pipe tower component can be stably placed in the inner cavity of multiple bearing hooks 301 in a multi-point structure. Through one end of the bearing hook 301, the steel pipe tower component can be stably suspended and transported under the slide rail 100.

[0024] Furthermore, multiple auxiliary frames 500 slide on the slide rail 100. At the bottom of the auxiliary frame 500, a pull rope 600 for stabilizing the end of the steel pipe tower component is installed. The pull rope 600 is a high-strength wear-resistant rope. The pull rope 600 is spirally wound around the end of the steel pipe tower component. A friction strip 700 for grinding the end of the steel pipe tower component is installed in the middle of the pull rope 600. The pull rope 600 binds the friction strip 700 and wraps it around the outer wall of the steel pipe tower component to reduce frictional damage between the pull rope 600 and the outer wall of the steel pipe tower component. It should be further explained that the auxiliary frame 500 includes an auxiliary wheel 501, a bending rod 502, an inclined plate 503, and a second electric telescopic rod 504. The auxiliary wheel 501 rolls on the upper surface of the slide rail 100, allowing it to move along the track of the slide rail 100. Multiple bending rods 502 rotate and intersect at both ends of the auxiliary wheel 501 in a relatively torsional structure, allowing them to be mounted on both sides of the slide rail 100. The inclined plate 503 is fixed to the bottom of the multiple bending rods 502 in a downward-sloping structure, allowing it to be positioned above the horizontally arranged steel pipe tower component. The inclined plates 503 are staggered and located directly below the slide rail 100. The pull rope 60... One end of the first electric telescopic rod 500 is fixed to one end of the inclined plate 503. The second electric telescopic rod 504 is fixed to the bottom of the inclined plate 503. A fixing ring 505 is fixedly installed at the bottom of the second electric telescopic rod 504. The other end of the pull rope 600 is fixedly connected to the outer wall of the fixing ring 505. The second electric telescopic rod 504 is electrically connected to an external power source through an external controller. Driven by the second electric telescopic rod 504, the telescopic end of the second electric telescopic rod 504 can drive the end of the pull rope 600 to move telescopically, so that the pull rope 600 can tighten and loosen the end of the steel pipe tower component. This allows the pull rope 600 to limit the end of the steel pipe tower component and reduce the random swinging of the end of the steel pipe tower component.

[0025] Furthermore, the friction strip 700 includes a connecting strip 701 and a hook and loop fastener assembly 702. The connecting strip 701 is wound around the outer wall of the transported steel pipe tower component. The pull rope 600 is attached to the outer wall of the connecting strip 701 and binds the connecting strip 701 to the outer wall of the steel pipe tower component. Multiple hook and loop fastener assemblies 702 are fixed at equal intervals to the outer wall of the connecting strip 701. The hook and loop fastener assemblies 702 are used to bind the pull rope 600 to the connecting strip 701. The hook and loop fastener assemblies 702 include hook and loop fasteners and loop fasteners. The hook and loop fasteners are fixed to the outer wall of the connecting strip 701, and the loop fasteners are fixed to the outer wall of the pull rope 600. The hook and loop fasteners are bonded and fixed. Through the fixation of the hook and loop fasteners, the connecting strip 701 can be stably attached to the outer wall of the pull rope 600. The connecting strip 701 includes a rubber strip 711, an adhesive layer 712, and sandpaper 713. The rubber strip 711 is fixed to the bottom of multiple Velcro assemblies 702, and the hook-and-loop fasteners are fixed to the outer wall of the rubber strip 711. The adhesive layer 712 is applied to the lower surface of the rubber strip 711, and the sandpaper 713 is adhered to the lower surface of the adhesive layer 712. The abrasive surface of the sandpaper 713 is attached to the outer wall of the steel pipe tower component. By pulling the pull rope 600, the sandpaper 713 can be pulled to remove burrs from the outer wall of the attached steel pipe tower component, which facilitates the safe connection of the ends of the steel pipe tower components during the subsequent installation of the steel pipe tower.

[0026] Example 2: Based on Example 1, the second base plate 305 includes a plate body 351, bearing holes 352, positioning holes 353, and a snap-fit ​​assembly. The plate body 351 is fixed to the bottom of another bearing hook 301. Multiple bearing holes 352 are formed in the middle of the plate body 351. The snap-fit ​​rod 304 slides through the middle of the bearing holes 352. The positioning hole 353 is formed at the bottom of the plate body 351. The positioning hole 353 and the middle of the multiple bearing holes 352 are connected. The internal cavities are interconnected. The snap-fit ​​assembly is installed at the bottom of the plate 351. The snap-fit ​​assembly is used to simultaneously snap-fit ​​multiple snap-fit ​​rods 304. The snap-fit ​​assembly includes a snap-fit ​​block 354, a pull rod 355, a positioning plate 356, a positioning rod 357, and a compression spring 358. The snap-fit ​​block 354 slides through the internal cavity of the positioning hole 353. The top of the snap-fit ​​block 354 has a rack and pinion structure that interlocks with the bottom of the multiple snap-fit ​​rods 304, facilitating the sliding of the snap-fit ​​block 354 within the internal cavities of the multiple snap-fit ​​slots. The interlocking connection allows the locking block 354 to engage and limit the bottom of multiple locking rods 304, improving the stability of the positions of the multiple locking rods 304. The pull rod 355 is fixed to the middle of the locking block 354 and is used to slide and pull the locking block 354 in the cavity of the positioning hole 353. The outer wall of the positioning plate 356 is fixed to the outer wall of the plate body 351 by screws. The positioning plate 356 is used to close the cavity of the positioning hole 353. Multiple positioning rods 357 are fixed at equal intervals in the middle of the positioning plate 356. The positioning rods 357 are arranged longitudinally in the cavity of the positioning hole 353. The top of the positioning rod 357 is slidably interlocked with the side of the locking block 354. The sliding limitation of the locking block 354 by the positioning rod 357 facilitates the improvement of the stability of the locking block 354 in the cavity of the positioning hole 353. The compression spring 358 is sleeved on the outer wall of the positioning rod 357. The two ends of the compression spring 358 are respectively fixed between the locking block 354 and the positioning plate 356. In use, by pulling down the pull rod 355, the locking block 354 can be pressed down in the inner cavity of the positioning hole 353, which facilitates the compression of multiple compression springs 358, allowing the locking block 354 to slide out from the bottom of the locking rod 304. This facilitates the adjustment of the distance between the locking rod 304 and the plate 351, and the adjustment of the distance between two adjacent bearing hooks 301, thereby improving the stability of the position between two adjacent bearing hooks 301.

[0027] A method for producing and transporting a steel pipe tower, the method comprising the steel pipe tower production and transport apparatus as described above, specifically including the following steps: Step 1: Driven by the retraction of the telescopic end of the first electric telescopic rod 402, the connecting rod 404 can be pulled, so that the multiple L-shaped rods 405 can drive the limiting plate 302 to be pulled, so that the limiting plate 302 and the bearing hook 301 can be in an open state for the placement and bearing of the steel pipe tower component. Then, driven by the extension of the telescopic end of the first electric telescopic rod 402, the connecting block 403 can push the connecting rod 404, so that the multiple limiting plates 302 can press down on the inner cavity of the bearing hook 301, so that the limiting plate 302 can press down and lock the outer wall of the steel pipe tower component supported by the inner cavity of the bearing hook 301 for positioning. Step 2: The connecting strip 701 is bound to the middle of the pull rope 600 by multiple Velcro assemblies 702, and the pull rope 600 located at the end of the steel pipe tower is wound around the outer wall of the steel pipe tower, so that the outer wall of the connecting strip 701 can fit and wrap around the outer wall of the steel pipe tower. Driven by the second electric telescopic rod 504, the pull rope 600 drives the connecting strip 701 to lock on the outer wall of the steel pipe tower, which is used to control the end position of the steel pipe tower during the movement of the steel pipe tower. Step 3: When it is necessary to grind the burrs on the outer wall end of the steel pipe tower component, pull the pull rope 600 so that the connecting strip 701 wrapped around the outer wall of the steel pipe tower component can slide and rub against the outer wall of the steel pipe tower component, so that the burrs can be ground off by the sandpaper 713.
