Description

Technical Field

[0001] This invention relates to the field of rod connection, and in particular to a horizontal clamping and connection mechanism for large rods. Background Technology

[0002] In fields such as machinery manufacturing, steel structure construction, and large pipeline construction, the assembly of large structural members (such as long shafts, large pipes, and structural beams) is a critical process. These members are characterized by their large weight, long length, and bulky shape, which presents numerous challenges to their assembly.

[0003] Currently, the industry mostly uses a crude method of overhead crane hoisting and manual assistance for horizontal connection of such rods. This method relies on manual prying or dragging for fine-tuning and alignment, which is not only inefficient and labor-intensive, but also poses safety risks such as rod slippage and crushing. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that relying on manual prying or dragging for fine-tuning and centering is not only inefficient and labor-intensive, but also poses safety risks such as slippage and crushing of the rods.

[0005] The above-mentioned technical problems are solved by the following technical solution: This invention proposes a horizontal clamping and docking mechanism for large rods, which includes, A clamping component, comprising two sets of clamping frames and a central shaft, wherein the central shaft is hinged to the middle of both sets of clamping frames. The support component includes a support plate, two sets of sliding plates slidably disposed on one side of the support plate, and two sets of limiting plates slidably disposed on the other side of the support plate. Each set of sliding plates is connected to the limiting plate on the corresponding side via a connecting shaft. The ends of the two sets of clamping frames are respectively hinged to the two sets of connecting shafts. Specifically, the rod is installed and inserted between the two sets of clamping frames by hoisting. During insertion, the rod presses against the two sets of clamping frames, causing them to rotate around the central axis, thereby achieving adaptive adjustment of the opening of the two sets of clamping frames. At the same time, the ends of the two sets of clamping frames will also drive the sliding plate and the limiting plate to slide adaptively in opposite directions on the outside of the support plate through the connecting shaft. This sliding process ensures that the clamping force is evenly distributed, so that the two sets of clamping frames can stably and effectively perform initial centering and holding of the rod. Finally, by fixing the sliding plate and the limiting plate, the final rigid clamping and locking of the rod can be completed.

[0006] In a preferred embodiment of the large rod horizontal clamping and docking mechanism of the present invention: the clamping frame includes a clamping plate hinged to the central shaft, an extension plate fixedly connected to one end of the clamping plate, and a Mecanum wheel adapted to be installed on the inner side of the clamping plate; the clamping plate is L-shaped; Specifically, during the insertion of the rod, the Mecanum wheel can reduce the insertion resistance by rolling, protecting the surface of the rod; at the same time, when a small centering adjustment of the rod is required, the Mecanum wheel can enable the rod to move slightly laterally or longitudinally on its raceway, thereby achieving precise and labor-saving final centering positioning.

[0007] In a preferred embodiment of the large rod horizontal clamping and docking mechanism of the present invention: the central shaft includes a first sleeve, a first bolt threaded to the inside of the first sleeve, and a first nut threaded to the first bolt; the clamping plate is hinged to the first sleeve; by tightening the first bolt and the first nut, the clamping plate installed on the outer surface of the first sleeve can be limited to ensure the overall stability of the equipment operation.

[0008] In a preferred embodiment of the large rod horizontal clamping and docking mechanism of the present invention: the support plate is provided with sliding grooves on both sides of the sliding plate and the limiting plate, and the bottom end of the support plate is fixedly connected to the mounting rod.

[0009] In a preferred embodiment of the large rod horizontal clamping and docking mechanism of the present invention: a groove is provided on the side of the sliding plate opposite to the limiting plate, and a locking bolt is threaded into the groove; the sliding plate and the limiting plate are slidably disposed on both sides of the support plate through the groove, and the locking bolt is located inside the groove; Specifically, the groove ensures that the slide plate and the limiting plate can slide smoothly on both sides of the support plate; after the rod is clamped and positioned, tightening the locking bolt will cause its tail to press tightly against the groove wall, and the resulting huge friction will firmly lock the slide plate and the limiting plate onto the support plate, ensuring the stability of the rod clamping.

[0010] In a preferred embodiment of the large rod horizontal clamping and docking mechanism of the present invention: the connecting shaft includes a second sleeve, a second bolt threaded to the second sleeve, and a second nut threaded to the second bolt; the extension plate is hinged to the second sleeve; by tightening the second bolt and the second nut, it can be ensured that the second sleeve can be stably installed together with the slide plate and the limiting plate without displacement.

[0011] In a preferred embodiment of the large rod horizontal clamping and docking mechanism of the present invention: the sliding plate is slidably connected to the second sleeve, the limiting plate has a circular hole with a diameter smaller than that of the second sleeve, and the second bolt is threadedly connected to the second nut through the circular hole penetrating the limiting plate; Specifically, the above installation method ensures that one end of the second sleeve is not located between the sliding plate and the limiting plate, while the exposed part of the second sleeve end is hinged to a set of extension plates. Through the staggered hinge method, not only is a stable clamping structure constructed, but the stability of the second sleeve after installation can also be improved.

[0012] In a preferred embodiment of the large rod horizontal clamping and docking mechanism of the present invention: it further includes a frame, wherein the frame is elongated; Support columns are arranged sequentially along the length of the frame; The hydraulic lifting rod is provided at the top of the remaining support columns other than the support columns at both ends of the frame; The support plate is fixedly connected to the top of the support columns located at both ends via the mounting rod, and the support plate is fixedly connected to the output end of the hydraulic lifting rod at the top of the remaining support columns via the mounting rod. Specifically, the support columns at both ends of the frame provide a stable foundation for the rods, and the hydraulic lifting rods, which can be independently controlled at various points in the middle, can be raised and lowered precisely to actively lift or adjust the height of the support plate and thus adjust the position of the rods, ensuring that the entire clamped rods are adjusted to a horizontal or the required docking posture.

[0013] The beneficial effects of this invention are as follows: the linkage of the clamping frame, central shaft, sliding plate, limiting plate and connecting shaft realizes the adaptive centering and envelope of the rod; the use of Mecanum wheels significantly reduces insertion resistance and allows for precise centering with a small amount of force; the cooperation of locking bolts and slide grooves achieves final rigid clamping, ensuring clamping stability and reliability; at the same time, the independent and precise adjustment of the height of each support point by the hydraulic lifting rod ensures that it is always in the ideal horizontal docking posture, thereby significantly improving the accuracy, efficiency and safety of large rod docking operations as a whole.

[0021] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0023] Reference Figures 1-6 This embodiment provides a horizontal clamping and docking mechanism for large rods, which includes: The clamping component 1 includes two sets of clamping frames 11 and a central shaft 12, which is simultaneously hinged to the middle of the two sets of clamping frames 11. Support component 2 includes a support plate 21, two sets of sliding plates 22 slidably disposed on one side of the support plate 21, and two sets of limiting plates 23 slidably disposed on the other side of the support plate 21. Each set of sliding plates 22 is connected to the corresponding limiting plate 23 via a connecting shaft 24. The ends of the two sets of clamping frames 11 are respectively hinged to the two sets of connecting shafts 24. Specifically, the rod is installed and inserted between the two sets of clamping frames 11 by hoisting. During the insertion process, the rod presses the two sets of clamping frames 11, causing them to rotate around the central axis 12, thereby achieving adaptive adjustment of the opening of the two sets of clamping frames 11. At the same time, the ends of the two sets of clamping frames 11 will also drive the sliding plate 22 and the limiting plate 23 to slide adaptively in opposite directions on the outside of the support plate 21 through the connecting shaft 24. This sliding process ensures that the clamping force is evenly distributed, so that the two sets of clamping frames 11 can stably and effectively perform initial centering and holding of the rod. Finally, by fixing the sliding plate 22 and the limiting plate 23, the final rigid clamping and locking of the rod can be completed.

[0024] The clamping frame 11 includes a clamping plate 111 hinged to the central shaft 12, an extension plate 112 fixedly connected to one end of the clamping plate 111, and a Mecanum wheel 113 adapted to be installed on the inner side of the clamping plate 111; the clamping plate 111 is L-shaped. Specifically, during the insertion of the rod, the Mecanum wheel 113 can reduce the insertion resistance by rolling, thus protecting the surface of the rod. At the same time, when a small centering adjustment of the rod is required, the Mecanum wheel 113 can enable the rod to move slightly laterally or longitudinally on its raceway, thereby achieving precise and labor-saving final centering positioning.

[0025] The central shaft 12 includes a first sleeve 121, a first bolt 122 threadedly connected to the inside of the first sleeve 121, and a first nut 123 threadedly connected to the first bolt 122; the clamping plate 111 is hinged to the first sleeve 121; by tightening the first bolt 122 and the first nut 123, the clamping plate 111 installed on the outer surface of the first sleeve 121 can be limited to ensure the overall stability of the equipment operation.

[0026] As one embodiment provided, such as Figures 2-6 The support plate 21 is provided with a sliding plate 22 and a limiting plate 23, and sliding grooves 211 are provided on both sides. The bottom end of the support plate 21 is fixedly connected to an installation rod 212.

[0027] A groove 221 is provided on the side of the slide plate 22 opposite to the limiting plate 23, and a locking bolt 222 is threaded into the groove 221; the slide plate 22 and the limiting plate 23 are slidably disposed on both sides of the support plate 21 through the groove 221, and the locking bolt 222 is located inside the slide groove 211. Specifically, the groove 221 ensures that the slide plate 22 and the limiting plate 23 can slide smoothly on both sides of the support plate 21. After the rod is clamped and positioned, tightening the locking bolt 222 will cause its tail to press tightly against the groove wall of the slide groove 211. The resulting huge friction will firmly lock the slide plate 22 and the limiting plate 23 onto the support plate 21, ensuring the stability of the rod clamping.

[0028] The connecting shaft 24 includes a second sleeve 241, a second bolt 242 threadedly connected to the second sleeve 241, and a second nut 243 threadedly connected to the second bolt 242; the extension plate 112 is hinged to the second sleeve 241; by tightening the second bolt 242 and the second nut 243, it can be ensured that the second sleeve 241 can be stably installed together with the slide plate 22 and the limiting plate 23 without displacement.

[0029] The slide plate 22 is slidably connected to the second sleeve 241. The limiting plate 23 has a round hole with a diameter smaller than that of the second sleeve 241. The second bolt 242 is threadedly connected to the second nut 243 through the round hole that passes through the limiting plate 23. Specifically, the above installation method ensures that one end of the second sleeve 241 is not located between the slide plate 22 and the limiting plate 23, while the exposed part of the second sleeve 241 is hinged to a set of extension plates 112. Through the staggered hinge method, not only is a stable clamping structure constructed, but the stability of the second sleeve 241 after installation is also improved.

[0030] As one embodiment provided, such as Figure 1 It also includes rack 3, which is elongated. Support columns 31 are arranged sequentially along the length of the frame 3; Hydraulic lifting rod 32 is provided at the top of the remaining support columns 31 other than the support columns 31 at both ends of the frame 3. The support plate 21 is fixedly connected to the top of the support columns 31 located at both ends via the mounting rod 212, and the support plate 21 is fixedly connected to the output end of the hydraulic lifting rod 32 at the top of the remaining support columns 31 via the mounting rod 212. Specifically, the support columns 31 at both ends of the frame 3 provide a stable foundation for the rod, and the hydraulic lifting rod 32, which can be independently controlled at each point in the middle, can be raised and lowered precisely, thereby actively lifting or adjusting the height of the support plate 21 and thus adjusting the position of the rod, ensuring that the entire clamped rod is adjusted to a horizontal or the required docking posture.

[0031] In summary, the rod is inserted between the two sets of clamping frames 11 by hoisting. The rod presses against the L-shaped clamping plate 111 and its Mecanum wheel 113, causing the two sets of clamping frames 11 to rotate around the central axis 12 that is hinged in the middle, achieving adaptive adjustment of the opening. At the same time, the extension plate 112 at the end of the clamping frame 11 drives the sliding plate 22 and the limiting plate 23 to slide towards each other in the sliding grooves 211 on both sides of the support plate 21 through the hinged connecting shaft 24, ensuring that the clamping force is evenly distributed and completing the initial centering and holding of the rod. During this process, the Mecanum wheel 113 significantly reduces the insertion resistance by rolling, protecting the surface of the rod and allowing the rod to make slight lateral or longitudinal movements. The movement achieves precise alignment; after the rod is positioned, the locking bolt 222 in the groove 221 of the slide plate 22 is tightened, so that its tail abuts against the groove wall of the slide groove 211. The slide plate 22 and the limiting plate 23 are firmly locked by friction, and then the rod is finally rigidly clamped by the connecting shaft 24 and the clamping frame 11. In addition, the entire support component 21 is mounted on the long frame 3 by the mounting rod 212 at its bottom end. The support columns 31 at both ends of the frame 3 provide stable support, while the hydraulic lifting rods 32 at the top of the other support columns 31 can be raised and lowered independently and precisely, actively adjusting the height of the support plate 21 to ensure that it is precisely adjusted to the ideal horizontal docking posture.

[0032] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
