Description

Technical Field

[0001] This invention relates to the field of joint technology in iron tower production, specifically to a jointing and docking device for iron tower bodies. Background Technology

[0002] In the construction of power grids, power transmission towers are crucial equipment supporting power cable transmission lines. Common steel pipe towers consist of a tubular base and a tower body assembled together. During the welding process, the pipe tower is compressed and joined together, and then the joints are welded together using welding equipment to form a closed tower body.

[0003] According to a search, Chinese patent CN216607830U discloses a jointing device for support pipes in iron tower bodies. This device can quickly align and tighten two pre-made semi-circular iron pipes, ensuring a neat joint with minimal deviation. Furthermore, this jointing device is applicable to the jointing of support pipes of various specifications, offering high efficiency, low error, time and labor savings, and greatly ensuring work efficiency and quality.

[0004] The above-mentioned technical solution uses clamps and pressure plates to press the support tube. However, this support tube is circular in shape. When joining and connecting multi-faceted tower tubes, the conventional extrusion clamping method can easily cause warping and misalignment when aligning the gaps to be welded. At the same time, the conventional method of extruding and clamping multi-faceted tower tubes cannot achieve multi-directional correction, which can easily cause multiple facets of the tower tube to deform during welding. Summary of the Invention

[0005] The purpose of this invention is to provide a jointing device for iron tower bodies to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tower body jointing device, comprising a support frame and a tower tube, wherein the support frame has an inner recess in the middle and a support seat is installed on the surface of the inner recess, and the support seat supports multiple outer edges below the tower tube.

[0007] The middle of both sides of the lifting frame is slidably connected to an arc-shaped track, and a crossbar is connected to the arc-shaped track. The crossbar is connected to a hydraulic rod on the side of the lifting frame. The arc-shaped track is slid out from both sides of the lifting frame by the extension of the hydraulic rod.

[0008] The two sides of the support frame are provided with a folding mechanism that moves and unfolds following the arc track. The hydraulic rod pushes the arc track out of the support frame, so that the folding mechanism climbs up from both sides of the tower tube along the arc track. The arc climbing of the folding mechanism can fold and straighten the tower tube that is not closed on the support frame.

[0009] The retracting mechanism includes a tail frame that docks with the lifting frame. The tail frame consists of a fixed frame and a movable frame. The fixed frame is installed at the end positions on both sides of the lifting frame. A front frame that moves with the arc track is provided on the side of the arc track near the crossbar. A movable frame that moves with the front frame is provided between the fixed frame and the front frame.

[0010] The front and rear frames are also equipped with a pressing mechanism that aligns the seams of the tower tubes by pressing multiple outer edges of the tower tubes.

[0011] Preferably, the front frame, fixed frame, and movable frame on the same side of the lifting frame are symmetrically distributed with respect to the center line of the crossbar;

[0012] Slide rails are installed on the side of the two front frames that are far apart from each other and on the side of the movable frame that is close to the fixed frame. Flanges that move along the inside of the slide rails are provided on the side of the movable frame that is close to the front frame and on the side of the fixed frame that is close to the movable frame.

[0013] Both the fixed and movable frames near the flange are fixed with locating pins, and the inner wall of the slide rail has an arc-shaped channel to limit the movement of the locating pins.

[0014] Preferably, the tube pressing mechanism includes a fixing plate horizontally installed on the inner wall of the front frame and the rear frame. A support rail is provided on one side of the fixing plate, and a symmetrically arranged oblique shoulder is provided on the other side of the fixing plate. Tube pressing claws are slidably connected to the oblique shoulder.

[0015] Preferably, the pressure claw is fixed with a guide pin on the side near the support rail, and the surface of the support rail is symmetrically slidably connected with traction sleeves that mate with the guide pins, and a tension spring is connected between the two traction sleeves.

[0016] Preferably, the support rail is hinged and rotatably connected to a locking hook in the middle, a magnetic block is installed on one side of the locking hook, the two sides of the middle of the support rail have recessed channels, and a lever pressing part is provided at the end of the locking hook near the recessed channel.

[0017] Preferably, a magnetic slider is fixed in the center of the upper and lower sides of the fixing plate. The magnetic slider slides with the unlocking component located between the two pressing claws. The magnet embedded on one side of the magnetic slider slides with the reserved grooves on both sides of the unlocking component, so that the unlocking component close to the front trigger part of the pressing claw fits against the tower tube.

[0018] The width of the trigger part at the front end of the unlocking component is greater than the width of the pressure claw.

[0019] Preferably, the inner walls on both sides of the unlocking member are provided with protrusions, and the unlocking member, which runs through the recessed channel in the middle of the support rail, can drive the protrusions to push the lever pressing part at the end of the lock hook.

[0020] Preferably, the lifting frame is provided with movable limiting mechanisms at both ends near the concave opening. The movable limiting mechanisms provide sizing support for the inner walls of both ends of the tower tube and fasten the top of the outer walls of both ends of the tower tube. The limiting mechanism includes a base installed at both ends of the lifting frame. A motor is installed on the outer side of the base, and a gear is connected to the output end of the motor.

[0021] Preferably, a rotating seat that passes through an output end of a motor is movably connected to the inner wall of the base, and a top support spring is connected between the inner wall of the base and the rotating seat.

[0022] The rotating seat has a straight groove on its surface. The rotating seat is rolled to the bottom of the moving seat through the straight groove. The bottom surface of the moving seat is provided with a rack that meshes with the gear. Through the meshing of the gear and the rack, the rotating gear can drive the moving seat to move in the base.

[0023] Preferably, the top of the movable seat is provided with a height-adjustable top block, one side of the movable seat is longitudinally slidably connected with an anti-loosening plate, and the other side of the movable seat is equipped with a motor.

[0024] The output end of the second motor is connected to a cam, and the surface of the anti-loosening plate is provided with a parallel crossbeam that fits against the cam. A roller for fastening the outer edge of the tower tube is horizontally connected to the upper side of the anti-loosening plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: The tower body jointing device can drive the pressing mechanism to rotate and approach the outer edge of the tower tube by climbing and unfolding the retracting mechanism. At this time, the unlocking part squeezed by the outer edge will be unlocked, so that the pressing claw moves laterally to avoid collision. When the retracting mechanism is fully unfolded, the pressing mechanism squeezes the outer edge of the tower tube, thereby enabling fine adjustment and correction of multiple outer edges of the tower tube exposed on the support frame. This ensures that each edge of the tower tube can be retracted and corrected from bottom to top in multiple directions after bending. At the same time, the limiting mechanism provides sizing support for the inner wall of the tower tube and fastens the top wall, which can prevent the aligned weld gap from warping or misaligning. This ensures that the device can correct the joint gap of the tower body and improve the welding quality of the tower body joint. Attached Figure Description

[0038] 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.

[0039] Please see Figure 1 and Figure 2The present invention provides a technical solution: a tower body joint connection device, including a support frame 1 and a tower tube 2. The support frame 1 has an inner recess in the middle, and a support seat 101 is installed on the surface of the inner recess. The support seat 101 supports multiple outer edges below the tower tube 2.

[0040] In this embodiment, the support frame 1 is placed horizontally on the ground, and then the support base 101 is installed in the concave opening of the support frame 1. Subsequently, the bent tower tube 2 is lifted into the concave opening of the support frame 1 using hoisting equipment, and the support base 101 provides multi-point support for multiple edges of the tower tube 2, so that the unjointed tower tube 2 can be initially shaped on the support frame 1. At the same time, the aligned gaps of the tower tube 2 are set upwards, so that it is convenient for personnel to use welding equipment to perform internal and external welding operations on the butt joints of the tower tube 2 during subsequent welding.

[0041] Please see Figures 1-3 The middle of both sides of the support frame 1 is slidably connected to the arc-shaped track 3, and the arc-shaped track 3 is connected to the crossbar 301. The crossbar 301 is connected to the hydraulic rod 4 on the side of the support frame 1. The arc-shaped track 3 is slid out from both sides of the support frame 1 by the extension of the hydraulic rod 4. The two sides of the support frame 1 are provided with the retraction mechanism 5, which moves and unfolds with the arc-shaped track 3. The hydraulic rod 4 is used to push the arc-shaped track 3 out of the support frame 1, so that the retraction mechanism 5 climbs up from both sides of the tower tube 2 along the arc-shaped trajectory. The arc-shaped climbing of the retraction mechanism 5 can retract and straighten the tower tube 2 that is not closed on the support frame 1.

[0042] In this embodiment, the extension or retraction of the hydraulic rod 4 can drive the crossbar 301 and the arc track 3 to move. Since the arc track 3 is in a sliding docking state in the middle of both sides of the support frame 1, the arc track 3 can drive the folding mechanism 5 to unfold or fold on both sides of the outside of the tower tube 2. The unfolded folding mechanism 5 can be used to straighten the tower tube 2.

[0043] Please see Figure 3 and Figure 4 The retracting mechanism 5 includes a tail frame 502 that docks with the lifting frame 1. The tail frame 502 consists of a fixed frame and a movable frame. The fixed frame is installed at the end positions on both sides of the lifting frame 1. A front frame 501 that moves with the arc track 3 is provided on the side of the arc track 3 near the crossbar 301. A movable frame that moves with the front frame 501 is provided between the fixed frame and the front frame 501.

[0044] The front frame 501, fixed frame, and movable frame on the same side of the lifting frame 1 are symmetrically distributed around the center line of the crossbar 301; the two front frames 501 on the side away from each other and the movable frame on the side close to the fixed frame are each equipped with a slide rail 503, and the movable frame on the side close to the front frame 501 and the fixed frame on the side close to the movable frame are each provided with a flange 504 that moves along the inside of the slide rail 503; the fixed frame and the movable frame on the side close to the flange 504 are each fixed with a positioning pin 505, and the inner wall of the slide rail 503 is provided with an arc-shaped channel for limiting the movement of the positioning pin 505.

[0045] In this embodiment, the fixed frame and the movable frame of the front frame 501 and the rear frame 502 are combined and connected, so that the slide rail 503 on the side of the front frame 501 is slidably connected to the flange 504 on the side of the movable frame, and the positioning pin 505 on the side of the movable frame is slidably connected to the arc-shaped channel in the slide rail 503. Then, the flange 504 and the positioning pin 505 on the side of the fixed frame are respectively connected to the slide rail 503 on the side of the movable frame and the arc-shaped channel inside the slide rail 503. This allows the moving arc-shaped track 3 to drive the front frame 501 and the rear frame 502 to unfold or fold, ensuring that the folding mechanism 5 moves along the arc-shaped trajectory of the arc-shaped track 3 to achieve arc-shaped climbing or folding, thereby enabling the tower tube 2 exposed on the upper side of the concave opening of the support frame 1 to be folded and corrected.

[0046] Please see Figures 3-9 The front frame 501 and the tail frame 502 are also provided with a pressing mechanism 6, which aligns the seams of the tower tube 2 by pressing multiple outer edges of the tower tube 2. The pressing mechanism 6 includes a fixing plate 601 that is horizontally installed on the inner wall of the front frame 501 and the tail frame 502. A support rail 602 is provided on one side of the fixing plate 601, and a symmetrically arranged oblique shoulder is provided on the other side of the fixing plate 601. A pressing claw 603 is slidably connected to the oblique shoulder.

[0047] In this embodiment, the fixing plate 601 and the support rail 602 are horizontally installed on the inner wall of the front frame 501 and the tail frame 502. When the pressing claw 603 is squeezed, the pressing claw 603 will slide along the inclined shoulder of the fixing plate 601, thereby adjusting the distance with the tower tube 2 and making it convenient for the pressing claw 603 to avoid the outer edge of the tower tube 2.

[0048] Please see Figures 5-7 A guide pin 604 is fixed on the side of the pressure claw 603 near the support rail 602. A traction sleeve 605 that mates with the guide pin 604 is symmetrically slidably connected to the surface of the support rail 602. A tension spring 606 is connected between the two traction sleeves 605.

[0049] In this embodiment, when the two pressing claws 603 of the same pressing mechanism 6 are pressed and move along the inclined shoulder to avoid the outer edge of the tower tube 2, the mutual separation of the two pressing claws 603 will be caused by the extension and retraction of the guide pin 604 and the traction sleeve 605, so that the tension spring 606 of the two traction sleeves 605 becomes longer. When the pressing claws 603 are separated from the outer edge of the tower tube 2 and lose the pressing, the tension spring 606 resets and drives the two traction sleeves 605 to move closer to each other, so that the two pressing claws 603 can move closer to each other and move in the opposite direction along the inclined shoulder of the fixing plate 601. At this time, the two pressing claws 603 that are close to the tower tube 2 will press the outer edge of the tower tube 2 again.

[0050] Please see Figures 5-7 The support rail 602 has a hinged locking hook 607 in the middle, and a magnetic block 608 is installed on one side of the locking hook 607. The two sides of the middle of the support rail 602 have recessed channels, and the end of the locking hook 607 near the recessed channel is provided with a lever pressing part.

[0051] In this embodiment, when two adjacent pressure claws 603 approach each other and drive the guide pin 604 to move, the guide pin 604 will move on both sides of the support rail 602 and press the end of the locking hook 607, causing the locking hook 607 to rotate and drive the magnetic block 608 away from the support rail 602.

[0052] It should be noted that when the two clamping claws 603 come close to each other at their limit positions, the magnetic block 608, which is magnetically attracted to the support rail 602, will drive the locking hook 607 to reset and hook the guide pin 604, thereby preventing the clamping claws 603 from shifting position.

[0053] Please see Figures 3-9 A magnetic slider 609 is fixed in the center of the upper and lower sides of the fixing plate 601. The magnetic slider 609 slides with the unlocking member 610 located between the two pressure tube claws 603. The magnet embedded on one side of the magnetic slider 609 slides with the reserved grooves on both sides of the unlocking member 610, so that the front trigger part of the unlocking member 610 close to the pressure tube claw 603 fits against the tower tube 2. The width of the front trigger part of the unlocking member 610 is greater than the width of the pressure tube claw 603.

[0054] The inner walls on both sides of the unlocking component 610 are provided with protrusions 611. The unlocking component 610, which runs through the recessed channel in the middle of the support rail 602, can drive the protrusions 611 to push the lever pressing part at the end of the locking hook 607. The front frame 501 and the rear frame 502 are also provided with anti-deviation columns that are connected to the magnetic slider 609. The anti-deviation columns support the upper and lower positions of the magnetic slider 609, which can prevent the pressing tube mechanism 6 from being deformed by pressure.

[0055] In this embodiment, when the arc track 3 drives the front frame 501 to slide upward, the front frame 501 will cause the two pressing claws 603 and the front trigger part of the unlocking member 610 to press against the outer edge of the tower tube 2. Since the width of the front trigger part of the unlocking member 610 is greater than the width of the pressing claws 603, the unlocking member 610 will contact the outer edge of the tower tube 2 earlier than the pressing claws 603, and the contact time between the front trigger part of the unlocking member 610 and the outer edge of the tower tube 2 is longer than the contact time between the pressing claws 603 and the outer edge of the tower tube 2. Therefore, the rotating unlocking member 610 will cause the front trigger part to press against the outer edge of the tower tube 2, so that the unlocking member 610 will move along the magnetic slider 609.

[0056] When the protrusions 611 on both sides of the unlocking member 610 pass through the recessed channels on both sides of the middle of the support rail 602, the protrusions 611 will push the lever pressing part at the end of the locking hook 607, thereby causing the locking hook 607 to deflect and complete the disengagement and unlocking from the guide pin 604. At this time, the pressing claw 603 that contacts the outer edge of the tower tube 2 will slide along the inclined shoulder of the fixing plate 601 to avoid the tower tube 2.

[0057] It is important to note that when the upward-moving front frame 501 drives the movable frame of the tail frame 502 to unfold one by one, the pressing mechanism 6 inside the movable frame will also move in the same way as the pressing mechanism 6 in the front frame 501 to avoid the outer edge of the tower tube 2.

[0058] When the front frame 501 drives the rear frame 502 to fully unfold and the front trigger part of the pressing claw 603 and the unlocking member 610 aligns with the outer edge of the tower tube 2, the magnetic slider 609 attracts the unlocking member 610, allowing the protrusion 611 of the unlocking member 610 to pass through the recessed channel and the magnetic block 608 to attract the support rail 602, causing the locking hook 607 to reset; at the same time, the pressing claw 603, which has lost the pressure of the outer edge of the tower tube 2, will be reset and brought closer by the tension spring 606.

[0059] To ensure that the pressing claw 603 has sufficient compressive force to press against the outer edge of the tower tube 2, two traction sleeves 605 are manually squeezed together. This causes the traction sleeves 605 to drive the guide pin 604 and the pressing claw 603 to move closer together. At this time, the pressing claw 603 moves towards the center of the inclined shoulder of the fixing plate 601. When the guide pin 604 is hooked by the locking hook 607, the pressing claw 603 can continuously press against the outer edge of the tower tube 2. This allows for fine-tuning and straightening of multiple outer edges of the tower tube 2 exposed on the support frame 1, ensuring that each edge of the tower tube 2 can be bent. The compression and straightening mechanism gradually shrinks from bottom to top, ensuring that the gap at the joint can be gradually reduced. During the process of the pressing claw 603 pressing the outer edge of the tower tube 2, the combined splicing strength of the arc track 3, the front frame 501 and the tail frame 502 can provide structural support for the pressing mechanism 6 to press the outer edge of the tower tube 2. When the unwelded tower tube 2 has an outward pressing force, the reverse pressing of the outer edge of the tower tube 2 against the pressing claw 603 will not cause the guide pin 604 to disengage from the locking hook 607, thereby preventing the pressing claw 603 from moving laterally to avoid the outer edge of the tower tube 2.

[0060] To address the warping and misalignment issue at the joint between the two ends of tower tube 2, the following features are also included:

[0061] Please see Figure 1 , Figure 2 , Figure 10 and Figure 11 The support frame 1 is provided with movable limiting mechanisms 7 at both ends near the concave opening. The movable limiting mechanisms 7 provide sizing support for the inner walls at both ends of the tower tube 2 and fasten the top of the outer walls at both ends of the tower tube 2. The limiting mechanism 7 includes a base support 701 installed at both ends of the support frame 1. A motor 702 is installed on the outside of the base support 701. The output end of the motor 702 is connected to a gear 705.

[0062] A rotating seat 703, which passes through the output end of motor 702, is movably connected to the inner wall of the base 701. A top support spring 706 is connected between the inner wall of the base 701 and the rotating seat 703.

[0063] The rotating seat 703 has a straight groove 704 on its surface. The rotating seat 703 is rolledly connected to the bottom of the movable seat 707 through the straight groove 704. The bottom surface of the movable seat 707 is provided with a rack that meshes with the gear 705. Through the meshing of the gear 705 and the rack, the rotating gear 705 can drive the movable seat 707 to move in the base 701.

[0064] In this embodiment, the top support spring 706 pushes the rotating seat 703, causing the rotating seat 703 to flip until the straight groove 704 is in a horizontal state. Then, the motor 702 drives the gear 705 to rotate forward. The gear 705 will mesh forward with the rack on the bottom surface of the moving seat 707, thereby causing the moving seat 707 to move forward along the straight groove 704, so that the moving seat 707 can be moved into the tower tube 2.

[0065] When the starting motor 702 drives the gear 705 to reverse, the movable seat 707 will move in the opposite direction along the straight groove 704 and be led out of the tower tube 2. When the movable seat 707 moves in the opposite direction to the limit end of the stroke of the straight groove 704, the gear 705, which continues to reverse, will push the rack and cause the movable seat 707 to push the rotating seat 703, thereby causing the rotating seat 703 to flip and compress the top support spring 706. At this time, the movable seat 707 will deflect to a position away from the tower tube 2, which facilitates the lifting and removal of the welded tower tube 2, and also facilitates personnel to enter the tower tube 2 to perform slag removal and welding quality inspection.

[0066] Please see Figure 1 , Figure 2 , Figure 10 and Figure 11 The top of the movable seat 707 is provided with an adjustable height top block 708. A locking plate 709 is longitudinally slidably connected to one side of the movable seat 707. A motor 710 is installed in the middle of the other side of the movable seat 707. A cam 711 is connected to the output end of the motor 710. A parallel crossbeam that fits against the cam 711 is provided on the surface of the locking plate 709. A roller for fastening the outer edge of the tower tube 2 is horizontally connected to the upper side of the locking plate 709.

[0067] In this embodiment, by starting the second motor 710 to drive the cam 711 to rotate downward, the cam 711 can press the lower side of the parallel crossarm, causing the anti-loosening plate 709 to move downward and drive the roller to tightly fasten the outer edge of the top of the tower tube 2, preventing the outer edge of the tightly fastened tower tube 2 from curling upward and causing the weld gap to be misaligned, and making the outer edge of the top of the tower tube 2 horizontally and tightly attached to the top block 708.

[0068] Conversely, when the motor 710 drives the cam 711 to rotate upward, the cam 711 can press the upper side of the parallel crossarm, causing the anti-loosening plate 709 to move upward and drive the roller away from the outer edge of the top of the tower tube 2, thereby facilitating the separation of the limiting mechanism 7 from the welded tower tube 2.

[0069] The top block 708 and the movable seat 707 are connected by a lead screw and a nut. The lead screw is fixed to the bottom surface of the top block 708 and is slidably connected to the top of the movable seat 707. The nut is sleeved on the outside of the lead screw. By rotating the nut along the lead screw, the top block 708 can be adjusted up and down on the top of the movable seat 707.

[0070] In this embodiment, when the movable seat 707 moves horizontally into the interior of the tower tube 2, the top block 708 will follow and move into the tower tube 2. By using the rotating nut and the screw thread drive, the upward-moving top block 708 can press the outer edge of the top of the tower tube 2, so that the outer edge of the top of the tower tube 2 is in a horizontal position. This allows the gap to be welded on the top of the tower tube 2 to be aligned, and it can support the upper and lower sides of the tower tube 2 lying horizontally on the support seat 101, ensuring that the tower tube 2 has the function of sizing support and shaping when it is placed horizontally.

[0071] Working principle: First, the cut steel plate is bent using a bending machine. Then, the bent steel plate is clamped together by the gathering mechanism 5, the pressing mechanism 6, and the limiting mechanism 7. After that, the inner side of the joint of the tower tube 2 is welded using welding equipment. Finally, the gathering mechanism 5 is folded and moved to both sides of the support frame 1, and the outer wall joint of the tower tube 2 restricted by the limiting mechanism 7 is welded a second time using welding equipment, thereby forming a sealed iron tower body. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
