[0036] like Figure 1-Figure 4As shown, in some examples, further, the welding mechanism 2 includes an annular slide 25 fixedly arranged at the top of the fixed outer ring 11, and also includes: two sliding seats 21, a connecting platform 22, a welding device 23 and a rotation drive device 24, the two sliding seats 21 are slidably arranged on the annular slide 25 in a circumferential direction; the connecting platform 22 is fixedly arranged at the top of the two sliding seats 21, wherein the two sliding seats 21 are respectively located at the two ends of the connecting platform 22; the welding device 23 is arranged on the top end face of the connecting platform 22 above one of the sliding seats 21; the rotation drive device 24 is fixedly installed on the other sliding seat 21, and the rotation drive device 24 is used to drive the connecting platform 22 and the welding device 23 to rotate.

[0037] In this example, the specific working process is as follows: two sliding seats 21 can be slidably arranged on the annular slide 25 along the circumferential direction, allowing them to move freely on the annular slide 25; the connecting platform 22 is fixedly arranged on the top of the two sliding seats 21, wherein the two sliding seats 21 are respectively located at the two ends of the connecting platform 22, such a design enables the connecting platform 22 to perform circular motion on the annular slide 25 with the support of the sliding seats 21; the welding device 23 is arranged on the top end face of the connecting platform 22 above one of the sliding seats 21, responsible for the actual welding operation, so as to weld and fix the modular upper steel pipe 200 to the lower steel pipe 100, thereby forming an integral steel tube concrete; the rotating drive device 24 is fixed It is installed on another sliding seat 21, and its main function is to drive the connecting platform 22 and the welding device 23 to rotate; when the rotating drive device 24 is started, it drives the connecting platform 22 and the welding device 23 to perform circular motion along the annular slide 25, and the welding device 23 welds the weld between the upper steel pipe 200 and the lower steel pipe 100 in this process; through this design, the welding mechanism 2 can achieve uniform and efficient circular welding, ensuring that the connection between the upper steel pipe 200 and the lower steel pipe 100 is firm and well sealed; the whole process has a high degree of automation, which reduces the complexity of manual operation and improves the accuracy and efficiency of welding, thereby ensuring the quality and reliability of steel tube concrete modular assembly.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, in some examples, further, the clamping mechanism 3 includes: a rotating ring 31, a driving groove 32, an abutting driving device 33, an arc groove 34 and a telescopic device 36, the rotating ring 31, the rotating ring 31 can be rotated around the axis of the steel pipe and is clamped on the bottom end of the fixed outer ring 11; the driving groove 32, multiple driving grooves 32 are opened in the outer wall of the bottom end of the rotating ring 31; the abutting driving device 33 is movable in the direction of approaching or moving away from the steel pipe and is arranged below the rotating ring 31; the arc groove 34 is opened through the rotating ring 31, and a connecting column 35 rotatably connected to the fixed outer ring 11 is arranged at one end of the arc groove 34; the telescopic device 36 is movably arranged at the bottom end of the rotating ring 31, and the output end of the telescopic device 36 is connected to the connecting column 35.

[0040] like Figure 5 and Figure 7 As shown, in some examples, further, multiple drive grooves 32 have the same shape and size, each drive groove 32 includes two ends, one end is at a different distance from the center line of the steel pipe than the end of another drive groove 32, and the drive groove 32 is arc-shaped or elongated.

[0041] In this example, it can be understood that the rotating ring 31 can rotate within a certain range on the fixed outer ring 11. A plurality of driving grooves 32 are provided on the outer wall at the bottom end of the rotating ring 31. These driving grooves 32 have the same shape and size. Each driving groove 32 is arc-shaped or elongated and has two ends. One end is at a different distance from the center line of the steel pipe than the end of another driving groove 32.

[0043] Specifically, the lifting and feeding mechanism 4 provided in this example is used in multiple links of the concrete grouting operation; the boss 41 is fixedly mounted on the outer walls of the two support rods 18 and is on the same side as the grouting hole 300 on the steel pipe; the sealing plate 42 is movably arranged on the inner side of the boss 41, and its main function is to seal the grouting hole 300 to prevent concrete leakage during the grouting process; the grouting pipe 43 is fixedly arranged on the sealing plate 42, and is used to introduce concrete into the steel pipe; a shielding portion 44 is provided in the middle position of the lower half of the inner wall of the sealing plate 42, and is located below the grouting hole 300. After the grouting is completed, the device is driven upward by the clamping mechanism 3, and ensures that the sealing plate 42 covers the position of the grouting hole 300 to seal the grouting hole 300.

[0044] The propulsion device 46 is fixedly arranged on the protrusion 41, and its core component is a propulsion block 47 that can be moved under force; the propulsion block 47 can abut against the outer wall of the sealing plate 42, and the state switching control of the sealing plate 42 is realized by the drive of the propulsion device 46; when grouting operation is required, the propulsion device 46 is started, and the propulsion block 47 pushes the sealing plate 42 to the grouting hole 300 of the steel pipe to ensure that the grouting hole 300 is completely sealed; then, concrete is injected into the steel pipe through the grouting pipe 43; during the grouting process, the sealing plate 42 is used to ensure that the concrete enters the steel pipe smoothly and prevents leakage; after the grouting is completed, the clamping mechanism 3 is used to drive the device to move upward, and the shielding part 44 seals the grouting hole 300 accordingly, waiting for the concrete inside the steel pipe to be formed, and at this time, a grouting operation is completed.

[0045] like Figure 5 and Figure 6 As shown, in some examples, further, the sealing plate 42 is also provided with: a guide column 45 and a spring 48, the guide column 45, the guide column 45 is parallel to the linear slide 15, the guide column 45 can move through the boss 41; the outer end diameter of the guide column 45 is larger than the middle diameter; the spring 48 is sleeved on the outer wall of the guide column 45 and is located between the end of the large diameter end of the guide column 45 and the boss 41, and is used to keep the sealing sheet and the steel pipe in a separated state by default.

[0048] In this example, accurate monitoring of the concrete liquid level inside the steel pipe is achieved through the liquid level monitoring mechanism 5; its working principle is as follows: the protrusion 51 is fixedly arranged between the fixed outer ring 11 and the support ring 12, and its outer end protrudes from the outside of the fixed outer ring 11, providing a stable support base; the first long rod 52 is fixedly installed on the top of the protrusion 51 and extends vertically upward, providing a basis for height adjustment for liquid level monitoring; the second long rod 53 can be telescopically arranged on the outer wall of the first long rod 52, and by adjusting the telescopic length of the second long rod 53, the height of the monitoring device 54 can be accurately adjusted to adapt to steel pipes of different heights.

[0049] When the concrete liquid level rises to a predetermined height, the monitoring device 54 will send a signal to prompt the operator to stop grouting to avoid over-grouting or under-grouting. In this way, it not only ensures the uniform filling of concrete inside the steel pipe and improves the construction quality, but also significantly improves the construction efficiency and safety. This setting ensures the smooth progress of the entire jacking and pouring process through precise liquid level monitoring, making the construction process more intelligent and automated, and reducing the complexity of manual operation and potential safety hazards.

[0050] like Figure 7 As shown, in some examples, further, the abutment drive device 33 includes: at least one height drive device 331, a limiting column 332, a limiting groove 333, and a roller 334. At least one height drive device 331 is arranged below the fixed outer ring 11 and the fixed inner ring 14 and can move closer to or away from the steel pipe direction; the limiting column 332 is fixedly arranged in the area corresponding to the fixed outer ring 11 in the top end face of the height drive device 331; the limiting groove 333 can be movably clamped on the outer side of the bottom end of the limiting block 16; the roller 334 is arranged on the output end of the height drive device 331 and can abut against the outer wall of the steel pipe; one of the height drive devices 331 corresponds to the force direction of the propulsion device 46.

[0051] In this example, the height driving device 331 adjusts the position of the device on the steel pipe through the movement of its output end, thereby realizing welding of the ends of the steel pipe at different heights and completing multi-stage grouting operations; specifically, a limiting column 332 is fixedly provided on the top end face of the height driving device 331, and the position of the limiting column 332 is mutually engaged with the driving groove 32 on the fixed outer ring 11. Therefore, with the help of the thrust of the driving groove 32 during rotation, it is ensured that the height driving device 331 can generate a movement trend close to or away from the moving direction of the steel pipe during movement, and the limiting groove 333 can be movably engaged with the outer side of the bottom end of the limiting block 16. Through the engagement of the limiting groove 333, the height driving device 331 will not deviate from the predetermined track, thereby stably approaching or moving away from the steel pipe to complete the clamping action.

[0052] The roller 334 is arranged on the output end of the height driving device 331 and can abut against the outer wall of the steel pipe. When the height driving device 331 is started, the roller 334 on the output end starts to rotate, and the contact surface between the roller 334 and the steel pipe reduces friction by rolling, ensuring that the height driving device 331 moves smoothly and does not damage the surface of the steel pipe.

For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
