Description

Technical Field

[0001] This utility model relates to the field of steel component connection technology, and in particular to a large steel component anti-misalignment connector. Background Technology

[0002] Steel components are an important part of steel structure engineering. They involve many aspects such as material selection, manufacturing process, connection technology, anti-corrosion treatment, fire protection technology, and structural stability. Steel components are usually made of steel plates, angle steel, channel steel, I-beams and other steel materials through welding or hot rolling. These materials have the characteristics of high strength, light weight, good overall rigidity and strong deformation capacity, making them suitable for building large-span, super-high and super-heavy buildings.

[0003] In the existing steel component connection process, when a single connecting plate is connected by welding or bolts, if it is necessary to move the steel component to align with the connecting plate, the large weight of the steel component can easily cause the threaded rod on the steel component to not align with the bolt on the connecting plate. This requires workers to constantly adjust the angle, increasing their working time. At the same time, the large weight of the steel plate itself can also cause misalignment of the connecting plate. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: In the connection process of existing steel components, when a single connecting plate is connected by welding or bolts, when it is necessary to move the steel component to align with the connecting plate, due to the large weight of the steel component, the threaded rod on the steel component is prone to not being aligned with the bolt on the connecting plate. Workers need to constantly adjust the angle, which increases the workers' labor time. At the same time, the large weight of the steel plate itself can also cause the connecting plate to be misaligned. Therefore, a large steel component anti-misalignment connector is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large steel component anti-misalignment connector includes a steel plate, a connecting plate, and a placement plate. The connecting plate is slidably connected to the steel plate, and two placement plates are fixedly connected to the connecting plate. An anti-misalignment component is installed on the placement plate, comprising a fixing plate, a straightening plate, a straight spring, a threaded rod, a limiting plate, and a compression chamber. The two fixing plates are fixedly connected to the upper surface of the placement plate, and the two straightening plates are slidably connected to the upper surface of the placement plate. The straightening plate is slidably connected to the fixing plate. The straight spring is fixedly connected between the straightening plate and the fixing plate. The two compression chambers are fixedly connected to the inner wall of the placement plate. A moving plate is slidably connected within each compression chamber. The threaded rod is rotatably connected to the placement plate. The limiting plate is threadedly connected to the threaded rod. A connecting rod is fixedly connected between the limiting plate and the moving plate.

[0007] Preferably, the upper surface of the straightening plate is inclined, the limiting plate is square, and one end of the threaded rod is provided with a rotating handle.

[0008] Preferably, one end of the placement plate is fixedly connected to two locking boxes, and the locking boxes are connected to the compression chamber through a connecting pipe.

[0009] Preferably, a locking plate is slidably connected inside the locking box, and a return spring is fixedly connected between the locking plate and the locking box.

[0010] Preferably, the locking plate is L-shaped, one end of the locking plate is slidably connected to the limiting plate, and multiple bolts are threadedly connected to the connecting plate, the bolts being threadedly connected to the steel plate.

[0011] Preferably, a shock-absorbing airbag is fixedly connected to the placement plate, and a rubber bladder is fixedly connected to the connecting plate. The rubber bladder is connected to the shock-absorbing airbag through an air inlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the cooperation of parts such as the fixing plate, straightening plate, straight spring, and threaded rod, the steel plate can enter the connecting plate at a predetermined position, ensuring that the steel plate will not shift during movement. This allows the threaded holes on the steel plate to be aligned smoothly with the bolts on the connecting plate, reducing workers' labor time and increasing fixing efficiency.

[0014] 2. By using shock-absorbing airbags, air intake pipes, rubber bladders and other components, the pressure of the steel plate on the connecting plate is reduced, avoiding misalignment under the weight of the steel plate itself, and increasing the overall support strength of the steel structure.

[0015] 3. Through the coordinated action of parts such as the compression chamber, moving plate, locking box, and locking plate, the locking plate moves to the outer surface of the limiting plate, locking the limiting plate and preventing it from loosening due to external vibration, thus ensuring overall stability and shock resistance and improving safety performance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A large steel component anti-misalignment connector includes a steel plate 1, a connecting plate 2, and a placement plate 3. The connecting plate 2 is slidably connected to the steel plate 1 and is I-shaped, made of high-strength steel. Two placement plates 3 are fixedly connected to the connecting plate 2. Anti-misalignment components are installed on the placement plates 3, including a fixing plate 4, a straightening plate 5, a straight spring 6, a threaded rod 7, a limiting plate 8, and a compression chamber 9. The straightening plate 5 has a groove, and the protruding end of the fixing plate 4 can slide within this groove. Both fixing plates 4 are fixedly connected to the placement plates. On the upper surface of plate 3, two straightening plates 5 are slidably connected to the upper surface of the placement plate 3. The straightening plates 5 are slidably connected to the fixing plates 4. A straight spring 6 is fixedly connected between the straightening plates 5 and the fixing plates 4. Two extrusion chambers 9 are fixedly connected to the inner wall of the placement plate 3. The extrusion chambers 9 contain a certain amount of gas. A moving plate 10 is slidably connected to the extrusion chambers 9. The moving plate 10 and the extrusion chambers 9 are treated to prevent air leakage. A threaded rod 7 is rotatably connected to the placement plate 3. A limiting plate 8 is threadedly connected to the threaded rod 7. A connecting rod 11 is fixedly connected between the limiting plate 8 and the moving plate 10.

[0024] The upper surface of the straightening plate 5 is inclined, and the inclined surface will contact the steel plate 1 immediately. The limiting plate 8 is square. One end of the threaded rod 7 is equipped with a rotating handle, which is used to facilitate the worker to rotate the threaded rod 7. One end of the placement plate 3 is fixedly connected to two locking boxes 12. The locking boxes 12 are connected to the extrusion chamber 9 through a connecting pipe 13. A locking plate 14 is slidably connected inside the locking box 12. The locking plate 14 and the locking box 12 are treated to prevent air leakage. The locking plate 14 and the locking box 12 are fixedly connected. A return spring 15 is attached, and the locking plate 14 is L-shaped. One end of the locking plate 14 is slidably connected to the limiting plate 8. Multiple bolts 19 are threadedly connected to the connecting plate 2, and the bolts 19 are threadedly connected to the steel plate 1. A shock-absorbing airbag 17 is fixedly connected to the placement plate 3. The shock-absorbing airbag 17 can relieve the pressure of the steel plate 1 moving onto the placement plate 3. A rubber bladder 18 is fixedly connected to the connecting plate 2. The rubber bladder 18 can expand and deform when inflated. The rubber bladder 18 is connected to the shock-absorbing airbag 17 through the air inlet pipe 16.

[0025] In this invention, a steel plate 1 is placed between two straightening plates 5. Under the weight of the steel plate 1, the two straightening plates 5 are initially pressed together and moved towards the fixed plate 4. As the steel plate 1 continues to move, when its upper surface passes through the inclined surface of the straightening plate 5, the steel plate 1 stops pressing the straightening plate 5, and the straightening plate 5 slides parallel to the steel plate 1. When the steel plate 1 is completely slid into the placement plate 3, the straightening plate 5, under the action of the straight spring 6, completely adheres to the side of the steel plate 1. Under the action of the two straightening plates 5, the steel plate 1 can enter the placement plate 3 at a predetermined position without any positional displacement. By rotating the threaded rod 7, the limiting plate 8 begins to push the steel plate 1 to move. Under the pushing action of the limiting plate 8, the steel plate 1 enters the connecting plate 2. Under the action of the straightening plates 5 on both sides of the steel plate 1, the steel plate 1 will not shift during the movement. This ensures that the threaded holes on the steel plate 1 are aligned with the bolts 19 on the connecting plate 2, preventing misalignment due to the movement of the steel plate 1. This reduces labor time and increases fixing efficiency. Simultaneously, the shock-absorbing airbag 17 on the plate 3 is compressed by the steel plate 1. The gas inside the shock-absorbing airbag 17 enters the rubber bladder 18 on the connecting plate 2 through the air inlet pipe 16. The rubber bladder 18 inflates, ensuring that when the steel plate 1 enters the connecting plate 2, it compresses the rubber bladder 18 instead of acting directly on the connecting plate 2. This reduces the pressure of the steel plate 1 on the connecting plate 2, prevents misalignment, and increases the overall support strength of the steel structure.

[0026] The movement of the limiting plate 8 drives the connecting rod 11 to move, and the connecting rod 11 pushes the moving plate 10 to move. The moving plate 10 squeezes the gas in the squeezing chamber 9 and enters the locking box 12 through the connecting pipe 13. The gas in the locking box 12 increases, the internal pressure increases, and the internal gas pushes the locking plate 14 to move outward. When the limiting plate 8 pushes the steel plate 1 completely into the connecting plate 2, the locking plate 14 moves to the outer surface of the limiting plate 8 and locks the limiting plate 8, preventing the limiting plate 8 from loosening due to external vibration, ensuring the overall stability and shock resistance, improving safety performance, and ensuring that the steel plate 1 will not slip out of the connecting plate 2.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
