Description

Technical Field

[0001] The present invention relates to the technical field of new infrastructure, and specifically to a steel bar fixing mechanism for new infrastructure. Background Art

[0002] New infrastructure construction (abbreviated as: new infrastructure) mainly includes seven major areas: 5G base station construction, ultra-high voltage, intercity high-speed railways and urban rail transit, new energy vehicle charging stations, big data centers, artificial intelligence, and the industrial Internet. It involves many industrial chains. It is an infrastructure system based on the concept of new development, driven by technological innovation, based on information networks, and aimed at the needs of high-quality development, providing services such as digital transformation, intelligent upgrades, and integrated innovation.

[0003] In the early stages of installation and pouring of new infrastructure signal towers, it is necessary to weld and pour the steel cages loaded with steel bars. During the production process of the steel cages, the steel bars need to be welded one by one manually.

[0004] In the patent application with application announcement number CN111851863A, it includes a base frame and two hooks respectively connected to the base frame. The openings of the hook grooves of the two hooks are away from the upper chord of the steel truss, and are hooked and connected to the two lower chords of the steel truss one by one. The fixing seat is connected to the base frame, and a mounting through hole is provided on the fixing seat. The fastener can pass through the mounting through hole and be connected to the fixed structure. The steel truss assembly component includes the above-mentioned steel truss fixing mechanism. In this invention, the hanging frame and the fixing seat cooperate with each other. There is no need to configure a set of mounting through holes for each lower chord. Only one set of mounting through holes is required to fix and install the steel truss, thereby reducing the position accuracy and dimensional accuracy of the processing mounting through holes, and the same set of mounting through holes can adapt to steel trusses of different sizes, with strong versatility.

[0005] In the prior art including the above-mentioned patents, during the welding and installation process of the existing steel cage, the steel bars on the annular steel cage frame need to be welded one by one, and the steel bars need to be manually held in this process. However, it is difficult to accurately locate the position of the steel bars by manual holding. The quality of manual welding is affected by many factors such as the welder's skill level, working environment, and equipment status, which can easily lead to unstable welding quality. Long-term manual welding work will cause welder fatigue and increase the risk of operational errors. Moreover, as a key component in the building structure, the accuracy of the position of the steel cage is directly related to the stability and safety of the entire structure. Inaccurate positioning of the steel bars of the steel cage will cause stress concentration or uneven distribution when the structure is under load, thereby affecting the overall stability and durability of the structure.

In actual engineering, the specifications, sizes and shapes of steel bars may vary, so the welding angle also needs to be adjusted accordingly. The steel bar fixing mechanism with angle adjustment function can adapt to steel bars of different specifications and meet various welding requirements, thereby improving the versatility and flexibility of the mechanism. In addition, the steel bar fixing mechanism with angle adjustment function makes the welding process more controllable and traceable.

Two limit seats slidably connected to the side sliding rod 28 are fixedly provided on one side of the main clamping seat 211. A handle is fixedly provided on the curved outer wall of the mounting assembly 21.

[0048] When the second steel bar 112 is welded, the main clamping seat 211 fixedly connected to the installation assembly 21 can be driven to slide on the outer wall of the annular frame 1 by pulling the handle. During this process, the steel bar clamping seat 26, which is first sleeved on the second steel bar 112, can rotate around the connection position with the swivel seat 25, and make the guide plate 261 on the steel bar clamping seat 26 slide on the outer wall of the arc-shaped guide strip 251 inside the swivel seat 25, and at the same time compress the reset spring 262. When the guide plate 261 fixed on the steel bar clamping seat 26 contacts the inner wall of one side of the swivel seat 25, the swivel seat 25 close to the second steel bar 112 can be driven to rotate around the connection position of the inner swivel shaft 23 and the adjusting cylinder 31 under the connection of the connecting rod 24 and the inner rotating shaft 23, and then the adjusting cylinder 31 and the inner rotating shaft are compressed. 23, and the swivel seat 25 near the first steel bar 111 side can, with the cooperation of the mounting assembly 2, rotate around the inner rotating shaft 23 near the first steel bar 111 side and the connection position of the adjusting cylinder 31, so that the two pairs of swivel seats 25 rotate synchronously. As the mounting assembly 21 continues to move, when the two pairs of steel bar clamping seats 26 are respectively separated from the first steel bar 111 and the second steel bar 112, the two pairs of swivel seats 25 can respectively drive the two swivel seats 25 to make circular motion under the elastic force of the two torsion spring bodies 231. At the same time, the two pairs of steel bar clamping seats 26 can respectively make the guide plates 261 on the steel bar clamping seats 26 contact the inner wall on the other side of the swivel seat 25 under the elastic force of the two return springs 262, as shown in FIG. Figure 3 At this time, the opening directions of the two pairs of steel bar clamping seats 26 are simultaneously upward. When the steel bar clamping seat 26 originally sleeved on the first steel bar 111 contacts the outer wall of the second steel bar 112, as the installation assembly 21 continues to move, the steel bar clamping seat 26 can rotate around the connection position with the rotating seat 25 and compress the return spring 262 between the rotating seat 25 and the steel bar clamping seat 26. At the same time, the rotation of the two steel bar clamping seats 26 near the side of the second steel bar 112 can drive the guide fixing rod 27 to rotate, and at the same time push the guide protrusion 22 slidingly connected to the guide fixing rod 27. 9 moves upward, and then drives the side sliding rod 28 fixedly connected to the guide protrusion 29 to move upward, and makes the other guide protrusion 29 move upward. At this time, the other guide fixing rod 27 can slide inside the other guide protrusion 29, and then drives the other two steel bar clamping seats 26 to rotate around the connection positions with the two rotating seats 25 respectively. At this time, the steel bar body 11 to be welded can be clamped to the two steel bar clamping seats 26 located above the main clamping seat 211, and the steel bar body 11 can be welded, thereby achieving the purpose of positioning the steel bar body 11.

[0049] Multiple elastic rubber sheets 32 are fixedly installed at both ends of the adjustment cylinder 31. Threaded plugs 33 are threadedly connected to both ends of the rotating cylinder 22. Two rubber rings 311 are fixedly installed on the inner wall of the rotating cylinder 22, and the two rubber rings 311 are respectively sleeved on the outside of the two groups of elastic rubber sheets 32. A cone 331 is fixedly installed inside each threaded plug 33.

[0050] The plurality of elastic rubber sheets 32 are distributed in an annular array, and the outer walls of the plurality of elastic rubber sheets 32 are in close contact with the inner wall of the rubber ring 311. The inner wall of the adjustment cylinder 31 is provided with a torsion spring groove that matches the torsion spring body 231.

[0051] The two threaded plugs 33 are connected to the rotating drum 22 by threads. The axial cross-section of each cone 331 is trapezoidal, and the arc-shaped outer wall of each cone 331 is tightly attached to the multiple elastic rubber sheets 32.

[0052] When it is necessary to adjust the angles of the two pairs of swivel seats 25, the threaded plugs 33 on the two rotating cylinders 22 can be screwed respectively, and the cones 331 on the threaded plugs 33 can be separated from the multiple elastic rubber sheets 32. At this time, the angles of the two pairs of swivel seats 25 can be adjusted. When adjusted to the desired position, the threaded plugs 33 can be screwed so that the cones 331 inside the threaded plugs 33 come into contact with the multiple elastic rubber sheets 32, and the cones 331, the multiple elastic rubber sheets 32 and the rubber rings 311 are in a close contact position with each other, thereby achieving the effect of adjusting the angles of the two pairs of swivel seats 25.

[0053] The working principle and usage process of the present invention are as follows: when the welding of the second steel bar 112 is completed, the main clamping seat 211 fixedly connected to the installation assembly 21 can be driven to slide on the outer wall of the annular frame 1 by pulling the handle. During this process, the steel bar clamping seat 26 first sleeved on the second steel bar 112 can be rotated around the connection position with the swivel seat 25, and the guide plate 261 on the steel bar clamping seat 26 slides on the outer wall of the arc-shaped guide strip 251 inside the swivel seat 25, and the reset spring 262 is compressed at the same time. When the guide plate 261 fixed on the steel bar clamping seat 26 contacts the inner wall of one side of the swivel seat 25, the swivel seat 25 close to the second steel bar 112 can be driven to connect with the adjustment cylinder 31 around the inner shaft 23 under the connection between the connecting rod 24 and the inner rotating shaft 23. The two pairs of swivel seats 25 rotate synchronously. As the mounting assembly 21 continues to move, when the two pairs of steel bar clamping seats 26 are separated from the first steel bar 111 and the second steel bar 112 respectively, the two pairs of swivel seats 25 can respectively drive the two swivel seats 25 to make circular motion under the elastic force of the two torsion spring bodies 231. At the same time, the two pairs of steel bar clamping seats 26 can respectively make the steel bar clamping seats 26 to make circular motion under the elastic force of the two return springs 262. The guide plate 261 on the seat 26 contacts the inner wall of the other side of the rotating seat 25. At this time, the opening directions of the two pairs of steel bar clamping seats 26 are simultaneously upward. When the steel bar clamping seat 26 originally sleeved on the first steel bar 111 contacts the outer wall of the second steel bar 112, as the installation assembly 21 continues to move, the steel bar clamping seat 26 can be rotated around the connection position with the rotating seat 25 and compress the return spring 262 between the rotating seat 25 and the steel bar clamping seat 26. At the same time, the rotation of the two steel bar clamping seats 26 close to the side of the second steel bar 112 can drive the guide fixing rod 27 to rotate, and at the same time push the guide protrusion 29 slidably connected to the guide fixing rod 27 to move upward, and then drive the side sliding rod 28 fixedly connected to the guide protrusion 29 to move upward, and make When the other guide protrusion 29 moves upward, the other guide fixing rod 27 can slide inside the other guide protrusion 29, thereby driving the other two steel bar clamping seats 26 to rotate around the connection position with the two rotating seats 25 respectively. At this time, the steel bar body 11 to be welded can be clamped to the two steel bar clamping seats 26 above the main clamping seat 211, and the steel bar body 11 can be welded. When adjusting the angles of the two pairs of rotating seats 25, the threaded plugs 33 on the two rotating cylinders 22 can be screwed respectively, and the cone cylinders 331 on the threaded plugs 33 are separated from the multiple elastic rubber sheets 32 respectively. At this time, the angles of the two pairs of rotating seats 25 can be adjusted. When adjusted to the desired position, the threaded plugs 33 can be screwed.The cone 331 inside the threaded plug 33 is in contact with the multiple elastic rubber sheets 32, and the cone 331, the multiple elastic rubber sheets 32 and the rubber ring 311 are in close contact with each other.
