Description

Technical Field

[0001] This utility model relates to the field of steel beam lifting equipment technology, and in particular to clamps for lifting steel beams in steel structure engineering. Background Technology

[0002] Steel structure engineering is a type of engineering structure that uses steel as the primary building material. It consists of various components, such as beams, columns, and trusses, assembled from steel profiles and plates through welding, bolting, or riveting. These components are then assembled into a complete structural system. Steel structure engineering offers advantages such as high strength, light weight, good seismic performance, fast construction speed, high degree of industrialization, and large space utilization, and is widely used in various construction projects including industrial plants, stadiums, exhibition halls, airport terminals, high-rise buildings, and bridges. During the design and construction of steel structure engineering, it is necessary to accurately consider factors such as the mechanical properties of the steel, the stress characteristics of the structure, and the reliability of connection nodes to ensure the safety and stability of the structure. Simultaneously, attention must be paid to protective measures such as corrosion prevention and fire protection to extend its service life and meet the requirements of different engineering environments.

[0003] Steel beam hoisting is a lifting operation method that uses steel beams as supports and lifting carriers. In environments such as construction sites or industrial production areas, steel beams are often used when it is necessary to lift heavy objects. Electric or manual hoists, winches, and other lifting equipment are typically installed on the steel beams. The object being lifted is connected to these equipment via ropes or chains. Thanks to its robust structure and strong load-bearing capacity, the steel beam can withstand the enormous tensile and gravitational forces generated during the lifting process, ensuring the safety of the operation.

[0004] However, existing clamps used for lifting steel beams in some steel structure projects cannot effectively clamp and fix steel beams of different sizes. Some clamps are often not flexible and adaptable enough in design. Faced with steel beams of different specifications and sizes on the construction site, they are difficult to perform satisfactorily. Whether it is a small steel beam with a narrow width and thin thickness or a large steel beam with a huge size and complex structure, the existing clamps cannot accurately and stably clamp and fix it effectively. This not only greatly affects the construction efficiency, but also poses a hidden danger to the safe progress of the project. Therefore, in order to solve the above problems, it is proposed to use clamps for lifting steel beams in steel structure projects. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a clamp for lifting steel beams in steel structure engineering, aiming to improve the problem that some existing clamps for lifting steel beams in steel structure engineering cannot effectively clamp and fix steel beams of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clamp for lifting steel beams in steel structure engineering includes a base plate. A driving assembly is provided on the top of the base plate. Sliding plates are fixedly connected to both sides of the driving assembly. Multiple limiting grooves are opened inside each of the two sliding plates. Limiting frames are slidably connected inside the multiple limiting grooves. Connecting frames are fixedly connected to the top of the multiple limiting frames. Limiting frames are slidably connected to the outside of the multiple connecting frames. A connecting plate is fixedly connected to the bottom of every two connecting frames. Clamping plates are fixedly connected to adjacent sides of the multiple connecting plates. Rubber plates are fixedly connected to adjacent sides of the multiple clamping plates. A guide assembly is provided at the bottom of the base plate. A top frame is fixedly connected to the top of the base plate. Lifting lugs are fixedly connected to the top of the top frame.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a housing, the bottom of which is fixedly connected to the top of the base plate. A cylinder is installed inside the housing, and two push rods are fixedly connected to the output end of the cylinder.

[0010] As a further description of the above technical solution:

[0011] The guiding assembly includes multiple guide frames, the bottoms of which are respectively fixedly connected to the tops of multiple connecting plates, and the bottom of the base plate is provided with multiple guide grooves;

[0012] As a further description of the above technical solution:

[0013] The inner side of the lifting lug is slidably connected to a sliding plate two. The bottom of the sliding plate two is fixedly connected to two sliding rods. Springs are sleeved on the outside of the two sliding rods. Limiting plates are fixedly connected to the bottom of the two sliding rods. A pressing plate is fixedly connected to the top of the sliding plate two. A soft pad is fixedly connected to the top of the pressing plate.

[0014] As a further description of the above technical solution:

[0015] The limiting frame is externally slidably connected to the inside of the sliding plate one, and the two push rods are respectively fixedly connected to the two sliding plates one on their adjacent sides;

[0016] As a further description of the above technical solution:

[0017] The bottom of the limiting frame is fixedly connected to the top of the base plate, and the outside of the connecting frame is slidably connected to the inside of the top frame;

[0018] As a further description of the above technical solution:

[0019] The guide frame is externally slidably connected to the inside of the guide groove, and the sliding rod is externally slidably connected to the inside of the lifting lug;

[0020] As a further description of the above technical solution:

[0021] One end of the spring is fixedly connected to the bottom of the sliding plate 2, and the other end of the spring is fixedly connected to the inside of the lifting lug.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the cylinder drives the sliding plate to a certain displacement, the limiting frame generates a vertical component force due to the inclination of the limiting groove, which drives the connecting frame to move. This allows the displacement of the clamping plate to be flexibly adjusted according to actual needs to adapt to steel beams of different widths. Simultaneously, the guide frame and guide groove in the bottom guide assembly of the base plate provide stable guidance when the connecting plate is displaced by the connecting frame, ensuring that the clamping plate can accurately and linearly clamp the steel beam, achieving reliable clamping of steel beams of different sizes from all directions.

[0024] 2. In this utility model, when connecting the hook, pressing the pressing plate causes the sliding plate two to slide down and compress the spring. After the hook passes through the lifting lug, the spring returns to its original position. The soft pad on the top of the sliding plate two tightly holds the hook to prevent it from shaking. The limiting plate prevents the sliding rod from coming out, maintaining the stability of the connection structure, effectively dealing with shaking and vibration during hoisting, and preventing the hook from accidentally falling off.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a clamp for lifting steel beams in steel structure engineering, including a base plate 1. The base plate 1 serves as the basic support component of the entire clamp. A drive assembly is provided on the top of the base plate 1. The drive assembly includes a housing 2, the bottom of which is fixedly connected to the top of the base plate 1. The housing 2 is the protective shell of the drive assembly. A cylinder 3 is installed inside the housing 2, which is the power source of the drive assembly. Two push rods 4 are fixedly connected to the output end of the cylinder 3. Sliding plates 5 are fixedly connected to both sides of the drive assembly. The far side of the two push rods 4 is fixedly connected to the near side of the two sliding plates 5. Under the push of the push rod 4, it can slide stably along a predetermined straight direction. Multiple limiting grooves 6 are opened inside the two sliding plates 5. The limiting frame 7 is slidably connected inside the multiple limiting grooves 6. The external of the limiting frame 7 is slidably connected inside the sliding plate 5. The top of the multiple limiting frames 7 is fixedly connected to the connecting frame 8. When the sliding plate 5 moves under the push of the push rod 4, the limiting frame 7 can generate a component force perpendicular to the movement direction of the sliding plate 5, thereby driving the connecting frame 8 to move, thereby realizing the clamping operation of the steel beam. The external of the multiple connecting frames 8 is slidably connected to the limiting frame 9, which is used to limit the displacement of the connecting frame 8.

[0033] The bottom of the limiting frame 9 is fixedly connected to the top of the base plate 1. A connecting plate 10 is fixedly connected to the bottom of every two connecting frames 8. Clamping plates 11 are fixedly connected to adjacent sides of the multiple connecting plates 10. The function of the connecting frame 8 is to transmit the movement of the limiting frame 7 to the connecting plate 10, thereby driving the clamping plates 11 to clamp the steel beam. Rubber plates 12 are fixedly connected to adjacent sides of the multiple clamping plates 11. The main function of the rubber plates 12 is to increase the friction with the surface of the steel beam when clamping it, preventing the steel beam from sliding during hoisting. A guide assembly is provided at the bottom of the base plate 1. The guide assembly includes multiple guide frames 13, the bottoms of which are respectively... The guide frame 13 is fixedly connected to the top of multiple connecting plates 10. Its function is to provide guidance for the connecting plates 10 during movement. Multiple guide grooves 14 are provided at the bottom of the base plate 1. The guide frame 13 is externally slidably connected to the inside of the guide grooves 14. A top frame 15 is fixedly connected to the top of the base plate 1. The main function of the top frame 15 is to further guide and limit the movement of the connecting frame 8. Together with the limiting frame 9, it ensures that the connecting frame 8 always moves along the predetermined trajectory during movement, thereby improving the stability and reliability of the entire fixture system. The connecting frame 8 is externally slidably connected to the inside of the top frame 15. A lifting lug 16 is fixedly connected to the top of the top frame 15.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The lifting lug 16 has a sliding plate 17 slidably connected inside. Two sliding rods 18 are fixedly connected to the bottom of the sliding plate 17. The sliding rods 18 are slidably connected to the inside of the lifting lug 16. Springs 19 are sleeved on the outside of the two sliding rods 18. One end of the spring 19 is fixedly connected to the bottom of the sliding plate 17, and the other end of the spring 19 is fixedly connected to the inside of the lifting lug 16. Through the elastic force of the springs 19, the sliding plate 17 automatically resets after the pressing plate 21 is released. Limiting plates 20 are fixedly connected to the bottom of the two sliding rods 18. The pressing plate 21 is fixedly connected to the top of the sliding plate 17. The operator controls the movement of the sliding plate 17 by pressing the pressing plate 21. A soft pad 22 is fixedly connected to the top of the pressing plate 21. The soft pad 22 can adapt to hooks of different shapes and sizes. Through its own deformation, it generates friction and squeezing force to firmly fix the hook in the lifting lug 16, preventing the hook from accidentally coming off during the lifting process and ensuring the safety of the lifting operation.

[0035] Working principle: When using the clamp for lifting steel beams in this steel structure project, first press down on the pressing plate 21 to make the sliding plate 17 slide inside the lifting lug 16. At this time, the sliding rod 18 will slide inside the lifting lug 16, which will compress the spring 19. Then the hook can be passed through the inside of the lifting lug 16. After releasing the sliding plate 17, the sliding plate 17 will be reset by the elastic force of the spring 19. Thus, the soft pad 22 can be used to limit and lock the hook.

[0036] Then, cylinder 3 can be activated to drive push rod 4 and sliding plate 5 to move. At this time, the limiting frame 7 will slide inside the limiting groove 6. With the help of the inclined design of the limiting groove 6, the connecting frame 8 will move, which will then drive the connecting plate 10 to move. At this time, the connecting frame 8 will slide inside the limiting frame 9, and the guide frame 13 will slide inside the guide groove 14. At this time, the displacement of the clamping plate 11 and the cooperation of the rubber plate 12 can be used to clamp and fix steel beams of different sizes.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
