A steel conveying equipment for bridge construction

Abstract

This invention discloses a steel conveying device for bridge construction, relating to the field of steel conveying technology. It includes a suspension frame and two clamping assemblies for clamping H-beams. Each clamping assembly includes a symmetrically arranged clamping frame I and clamping frame II. Two intersecting rotating arms are rotatably mounted on a central column. Vertical positioning blocks, vertically opposite to the H-beam, are vertically slidably mounted on both clamping frame I and clamping frame II. A locking assembly for locking the sliding plate is installed on a sleeve. This invention drives the rotating arms to rotate via a clamping drive assembly, allowing clamping frame I and clamping frame II to move closer together and clamp the H-beam for installation and positioning. After the push-slide plate engages, it pushes against the wedge surface I of the vertical positioning block, causing the vertical positioning block to move vertically downwards and clamp the H-beam. This achieves synchronous clamping of the H-beam in both the horizontal and vertical directions, significantly improving the stability of the H-beam conveying process.

Description

Technical Field

[0001] This invention relates to the field of steel conveying technology, specifically a steel conveying equipment for bridge construction. Background Technology

[0002] Bridge construction is a complex system engineering project integrating surveying and design, construction, inspection, and maintenance. It serves as a crucial hub connecting transportation networks and spanning rivers and valleys. In the early stages of construction, comprehensive geological, hydrological, and topographical surveys are required to determine the appropriate structural type, such as beam bridges, arch bridges, cable-stayed bridges, or suspension bridges, based on navigation and traffic requirements. During the construction phase, foundation work is carried out first, followed by the substructure and superstructure construction, and finally, the bridge deck system and ancillary works such as protection and lighting are completed. The entire process must strictly adhere to specifications, balancing construction efficiency and project quality. After completion, it must undergo systematic testing and acceptance, and regular maintenance is essential to ensure the long-term stable operation of the bridge.

[0003] During bridge construction, it is necessary to suspend and transport the required I-beams. However, current conveying devices typically use clamps to hold and fix the I-beams, but the contact area between the clamps and the I-beams is small. This makes it difficult to ensure the stability of the I-beams during hoisting, which can easily cause them to tilt or even slip, thus compromising the conveying efficiency and safety. To address these technical shortcomings of existing technologies, a steel conveying device for bridge construction is provided to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a steel conveying device for bridge construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A steel conveying device for bridge construction includes a suspension frame and two clamping assemblies for clamping I-beams. Each clamping assembly includes a clamping frame I and a clamping frame II symmetrically arranged. A central column is fixed at the center of the suspension frame, and two cross-arranged rotating arms are rotatably mounted on the central column. A clamping drive assembly for driving the clamping frames I and II to move toward the I-beams is mounted on the rotating arms. Vertical positioning blocks that are vertically opposite to the I-beams are slidably mounted on both clamping frames I and II. A pushing assembly for driving the vertical positioning blocks to slide vertically is mounted on both clamping frames I and II. A sliding plate is fixed on clamping frame I, and a square sleeve that slides and engages with the sliding plate is fixed on clamping frame II. A locking assembly for locking the position of the sliding plate is mounted on the sleeve.

[0006] As an improvement of the present invention: the clamping drive assembly includes two coaxially fixed threaded columns with opposite thread directions rotatably mounted on the bottom of the suspension frame. Each threaded column is threadedly fitted with a sliding frame that is slidably connected to the suspension frame. A push column is fixed on the sliding frame and abuts against the rotating arm. A hand crank is fixed at the end of the threaded column.

[0007] As an improvement of the present invention: the clamping drive assembly further includes a transmission column fixed on the clamping frame I and the clamping frame II, the transmission column being slidably mounted on the rotating arm, and a tray located above the rotating arm being fixed on the transmission column.

[0008] As an improvement of the present invention: an extension rod is fixed on the transmission column, the extension rod slides into the interior of the rotating arm, and a connecting spring I is sleeved on the extension rod, with the two ends of the connecting spring I fixed to the transmission column and the rotating arm respectively.

[0009] As an improvement of the present invention: the pushing assembly includes a pushing slide plate that is horizontally slidably mounted on the clamping frame I and the clamping frame II, the upper side wall of the vertical positioning block is provided with a wedge surface I corresponding to the pushing slide plate, the lower side wall of the vertical positioning block is provided with a wedge surface II, a fixing plate is fixed on the vertical positioning block, and a vertical spring is fixed between the fixing plate and the clamping frame II.

[0010] As an improvement of the present invention: the pushing assembly further includes an extension plate fixed on the pushing slide plate, and a connecting spring II is fixed between the extension plate and the clamping frame II. The pushing slide plate on the clamping frame I and the pushing slide plate on the clamping frame II are arranged horizontally opposite to each other.

[0011] As an improvement of the present invention: the locking assembly includes a plurality of equally spaced sliding wedges fixed on the sliding plate, a fixing frame fixed on the square sleeve, and a snap-fit ​​wedge adapted to snap-fit ​​the sliding wedges vertically slidably mounted on the fixing frame.

[0012] As an improvement of the present invention: an electric push rod is fixed on the square sleeve, and a traction frame is hinged between the telescopic end of the electric push rod and the snap-fit ​​wedge block.

[0013] As an improvement of the present invention: the end faces of the clamping frame I and the clamping frame II are rotatably mounted with side baffles, and the clamping frame I and the clamping frame II are fixed with positioning posts for limiting the side baffles.

[0014] As an improvement of the present invention: hooks are fixed to the top of both the central column and the transmission column.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention drives the rotating arm to rotate through the clamping drive assembly, which enables the clamping frame I and clamping frame II to move closer to each other to clamp and position the I-beam. During the clamping process, after the set push plate docks, it can push the wedge surface I of the vertical positioning block, causing the vertical positioning block to move vertically downward and clamp the I-beam. This achieves synchronous clamping operation of the I-beam in both the horizontal and vertical directions, and significantly improves the stability of the I-beam conveying process.

[0016] 2. In this invention, after clamping frame I and clamping frame II are connected, the sliding plate and the square sleeve are inserted and matched. The snap-fit ​​wedge and the sliding wedge are matched and matched, so that clamping frame I and clamping frame II can effectively lock the I-beam after clamping it, which greatly reduces the risk of the I-beam slipping off during hoisting and transportation, and ensures the stable transportation effect of the I-beam.

It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] First embodiment: Please refer to the appendix Figure 1 - Appendix Figure 8 A steel conveying device for bridge construction includes a suspension frame 2 and two clamping assemblies for clamping I-beams 1. Each clamping assembly includes a clamping frame I4 and a clamping frame II11 symmetrically arranged. A central column 7 is fixed at the center of the suspension frame 2. Two cross-arranged rotating arms 5 are rotatably mounted on the central column 7. A clamping drive assembly for driving the clamping frames I4 and II11 to move toward the I-beams 1 is mounted on the rotating arms 5. Vertical positioning blocks 32 that are vertically opposite to the I-beams 1 are vertically slidably mounted on both the clamping frames I4 and II11. A pushing assembly for driving the vertical positioning blocks 32 to slide vertically is mounted on both the clamping frames I4 and II11. A sliding plate 15 is fixed on the clamping frame I4. A square sleeve 24 that slides and engages with the sliding plate 15 is fixed on the clamping frame II11. A locking assembly for locking the position of the sliding plate 15 is mounted on the sleeve 24.

[0021] When transporting I-beams 1 during bridge construction using this conveying equipment, the I-beams 1 are clamped by two clamping components. The position of the I-beams 1 is moved by a crane or other hoisting equipment. Specifically, the clamping drive assembly of this equipment includes two coaxially fixed threaded columns 12 with opposite thread directions, which are rotatably installed at the bottom of the suspension frame 2. Each threaded column 12 is threadedly fitted with a sliding frame 31 that is slidably connected to the suspension frame 2. A push column 29 is fixed on the sliding frame 31, and the push column 29 abuts against the rotating arm 5. A hand crank 3 is fixed at the end of the threaded column 12. The clamping drive assembly also includes a transmission column 8 fixed on the clamping frame I4 and clamping frame II11. The transmission column 8 is slidably installed on the rotating arm 5, and a tray 9 located above the rotating arm 5 is fixed on the transmission column 8.

[0022] With the above structural arrangement, when the hand crank 3 is turned, the hand crank 3 can drive the threaded column 12 to rotate. At this time, the threaded column 12 drives the sliding frame 31 connected to it to slide. The two sliding frames 31 move closer to each other and drive the push column 29 to move towards the center column 7. That is, the push column 29 pushes the rotating arm 5 to rotate, thereby realizing that the rotating arm 5 drives the transmission column 8 to move. The transmission column 8 slides relative to the rotating arm 5, so that the transmission column 8 can drive the clamping frame I4 and clamping frame II11 to move closer to each other, realizing the clamping effect on the I-beam 1. The tray 9 is set to support the rotating arm 5. During the lifting process of the suspension frame 2, the rotating arm 5 can lift the transmission column 8 with the help of the tray 9, realizing the suspension and traction of the I-beam 1 by multiple transmission columns 8, ensuring the stable conveying and movement of the I-beam 1.

[0023] In addition, an extension rod 13 is fixed on the transmission column 8. The extension rod 13 slides into the rotating arm 5, and a connecting spring I14 is sleeved on the extension rod 13. The two ends of the connecting spring I14 are fixed to the transmission column 8 and the rotating arm 5, respectively. During the rotation of the rotating arm 5 relative to the central column 7, and the sliding of the transmission column 8 relative to the rotating arm 5, the extension rod 13 slides relative to the rotating arm 5, providing good guidance and limiting. At the same time, the extension rod 13 provides vertical traction to the transmission column 8, further improving the stability of the hoisting and transporting of the I-beam 1. By adjusting the hand crank 3 to drive the threaded column 12 connected to it, the clamping frame I4 and clamping frame II11 can quickly and stably clamp and position the I-beam 1. The operation is simple, stable, and efficient, effectively ensuring the conveying quality of the I-beam 1.

[0024] Second embodiment: Please refer to the appendix Figure 1 - Appendix Figure 8 Based on the first embodiment, the pushing assembly of this device includes a pushing slide plate 10 that is horizontally slidably mounted on the clamping frame I4 and the clamping frame II11. The upper side wall of the vertical positioning block 32 is provided with a wedge surface I27 corresponding to the pushing slide plate 10, and the lower side wall of the vertical positioning block 32 is provided with a wedge surface II28. A fixing plate 21 is fixed on the vertical positioning block 32, and a vertical spring 30 is fixed between the fixing plate 21 and the clamping frame II11.

[0025] In addition, the pushing assembly also includes an extension plate 25 fixed on the pushing slide plate 10. A connecting spring II26 is fixed between the extension plate 25 and the clamping frame II11. The pushing slide plate 10 on the clamping frame I4 and the pushing slide plate 10 on the clamping frame II11 are horizontally opposite to each other.

[0026] Based on the above structural configuration, during the horizontal clamping of the I-beam 1 by the clamping frame I4 and clamping frame II11, the I-beam 1 pushes against the wedge surface II28 of the vertical positioning block 32, causing the vertical positioning block 32 to move vertically upward until its lower end abuts against the top of the I-beam 1. Subsequently, after the pushing slide plate 10 on the clamping frame I4 and clamping frame II11 are connected, the wedge surface I27 of the vertical positioning block 32 abuts against the pushing slide plate 10, causing the vertical positioning block 32 to move vertically downward and push against the I-beam 1. This ensures that the I-beam 1 is vertically clamped and locked by the vertical positioning block 32 and the clamping frame I4 and clamping frame II11. In other words, the I-beam 1 achieves synchronous clamping and positioning in both the horizontal and vertical directions, greatly improving the clamping stability and operating efficiency of the I-beam 1, and making the conveying operation of the I-beam 1 more efficient.

[0027] Furthermore, the locking assembly of this device includes several equally spaced sliding wedges 16 fixed on the sliding plate 15. A fixing frame 22 is fixed on the square sleeve 24, and a snap-fit ​​wedge 23 that is vertically slidably mounted on the fixing frame 22 and is adapted to snap-fit ​​with the sliding wedges 16. An electric push rod 17 is fixed on the square sleeve 24, and a traction frame 18 is hinged between the telescopic end of the electric push rod 17 and the snap-fit ​​wedge 23.

[0028] During the docking process of clamping frame I4 and clamping frame II11, the sliding plate 15 extends into the square sleeve 24. The electric push rod 17 drives the snap-fit ​​wedge 23 to move toward the sliding plate 15 through the traction frame 18 until the snap-fit ​​wedge 23 engages with the sliding wedge 16, achieving a quick locking effect on the sliding plate 15. This ensures a secure lock after the clamping frame I4 and clamping frame II11 are docked, significantly improving the stability of the I-beam 1's conveying movement, effectively preventing the I-beam 1 from slipping, and enhancing the safety of the conveying process.

[0029] In addition, side baffles 19 are rotatably mounted on the end faces of clamping frames I4 and II11, and positioning posts 20 are fixed on clamping frames I4 and II11 to limit the movement of the side baffles 19. By rotating the side baffles 19 above the positioning posts 20, the end of the I-beam 1 is limited after clamping, further improving the stability of the I-beam 1 during transport. Rotating the side baffles 19 below the positioning posts 20 unlocks the end of the I-beam 1, making the operation simple and quick.

[0030] In addition, hooks 6 are fixed at the top of both the central column 7 and the transmission column 8. Multiple hooks 6 can be connected to external equipment. By connecting multiple ropes to the hooks 6, the force on the I-beam 1 can be more evenly distributed during hoisting and transportation, ensuring the stability of the I-beam 1 during transportation and improving the quality of transportation.

[0031] In summary, this invention, by driving the rotating arm 5 to rotate through the clamping drive assembly, enables the clamping frame I4 and clamping frame II11 to approach each other and clamp and position the I-beam 1. During the clamping process, the push-slide plate 10, after docking, pushes against the wedge surface I27 of the vertical positioning block 32, causing the vertical positioning block 32 to move vertically downward and clamp the I-beam 1. This achieves synchronous clamping of the I-beam 1 in both the horizontal and vertical directions, significantly improving the stability of the I-beam 1 during transport. Furthermore, after the clamping frame I4 and clamping frame II11 dock, the sliding plate 15 engages with the square sleeve 24, and the snap-fit ​​wedge 23 engages with the sliding wedge 16, effectively locking the clamping frame I4 and clamping frame II11 after clamping the I-beam 1. This greatly reduces the risk of the I-beam 1 slipping during hoisting and transport, ensuring stable transport of the I-beam 1.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
