The spacing between the baffles 9 and the sleeve 1 is the same as the thickness of the movable plate 5. The baffles 9 play the role of supporting and restricting the movable plate 5. Multiple movable plates 5 can be set on the side of the sleeve 1, that is, multiple rotating blocks 6 and U-shaped blocks 7 are set, so that multiple node plates can be installed, and the node plates can be adjusted in multiple directions. A rubber block 10 can be clamped between the rotating block 6 and the movable plate 5, and a rubber pad 11 can be clamped between the rotating block 6 and the annular plate 3. After the rotating block 6 is fixed in position, the rubber block 10 and the rubber pad 11 both play the role of positioning the rotating block 6 and at the same time play a buffering role.

[0040] As a technical optimization solution of the present invention, the rectangular sleeve mechanism includes a cylinder 12 coaxially sleeved with the interior of the sleeve 1, an inner sleeve block 13 fixed inside the cylinder 12, and a rectangular opening provided on the top of the inner sleeve block 13.

After the inner sleeve block 13 is sleeved on the rectangular steel pipe column, the cylinder 12 and the inner sleeve block 13 can be fixed to the rectangular steel pipe column by a plurality of bolts, thereby achieving the fixation of the sleeve 1 and the rectangular steel pipe column. The rectangular opening of the inner sleeve block 13 can be set in a variety of specifications, thereby matching rectangular steel pipe columns of various sizes.

[0041] As a technical optimization solution of the present invention, the clamping ring mechanism includes two mounting brackets 14, each mounted on one end of the two sleeves 1, facing away from each other.

Specifically, two cylinders are symmetrically rotatably connected to each mounting bracket 14, and the telescopic ends of the two cylinders are rotatably connected to the two semicircular ring blocks 15, respectively.

[0043] By clamping the two semicircular ring blocks 15 and the sleeve 1, the two semicircular ring blocks 15 corresponding to the two ends and the components thereon can be stably fixed on the two sleeves 1, and can then achieve the effect of self-movement, that is, the two semicircular ring blocks 15 at the bottom are separated first, and then the rotating motor on the upper mounting frame 14 controls the rotating frame 16 to rotate accurately 180 degrees, so that the connecting rod 17 and the two semicircular ring blocks 15 separated at the bottom are rotated to the top. At this time, the two separated semicircular ring blocks 15 close and clamp the steel pipe column. The two semicircular ring blocks 15 can adapt to clamping the steel pipe column of set specifications. At this time, continue to repeat the above operation, that is, the two semicircular ring blocks 15 at the bottom are separated and rotated to the top, and the effect of continuous movement of the whole on the steel pipe column can be achieved.

[0044] As a technical optimization solution of the present invention, the sliding structure includes a semicircular chute 18 arranged on two semicircular ring blocks 15. The two corresponding semicircular chute 18 can be connected to form a complete circular chute. An electric slider is provided for sliding matching in the circular chute, that is, the edges of the two semicircular ring blocks 15 are provided with racks, which are merged to form a circular rack. The electric slider includes a servo motor, and the servo motor drives a gear, which is engaged with the circular rack. The electric slider can perform precise circumferential displacement on the two semicircular ring blocks 15.

[0045] A flat plate 19 is horizontally fixed to the electric slider, driving it to perform precise circular displacement on the two semicircular ring blocks 15. The edges of the two semicircular ring blocks 15 are each fixed with a plurality of positioning holes 20, which align with the plurality of through-holes 4. A round ball 21 is connected to the flat plate 19 via a spring bar and engages with the positioning holes 20. When engaged with the positioning holes 20, the ball 21 stabilizes and positions the flat plate 19, ensuring that the flat plate 19 is aligned with each through-hole 4.

[0046] As a technical optimization solution of the present invention, the screw docking mechanism includes a first box body 22 that is removably fixed to the plate 19. Several fixed screws 23 are arranged inside the first box body 22. A first electric push rod 24 is provided on the side of the first box body 22 for pushing the several fixed screws 23. An outlet is provided at one end of the first box body 22 to match the fixed screws 23, through which the fixed screws 23 can be discharged. The first electric push rod 24 is used to push the several fixed screws 23 to the outlet, facilitating their subsequent discharge. A stop block is provided at the outlet to position the fixed screws 23. The stop block has a positioning slot 25, and a first electric telescopic rod is installed on the side of the first box body 22 to drive the stop block. The fixed screws 23 include a threaded rod and a hexagonal block. The positioning slot 25 of the stop block can be inserted into the hexagonal block of the fixed screw 23. The first box body 22 is used to position and discharge the fixed screws 23. The first box body 22 can be loaded with several fixed screws 23.

[0047] As a technical optimization solution of the present invention, the nut docking mechanism includes a second box body 26 that is detachably fixed to the flat plate 19. A plurality of fixing nuts 27 are stacked inside the second box body 26. The second box body 26 is provided with a placement cavity that matches the plurality of fixing nuts 27. A spring that abuts against the fixing nut 27 is provided at the bottom of the placement cavity. A second electric push rod 28 for pushing a fixing nut 27 to move is provided on the side of the second box body 26. A second electric telescopic rod 29 is vertically fixed to one end of the second box body 26. A power motor is fixed to the telescopic end of the second electric telescopic rod 29. A disc 33 is coaxially fixed to the power motor. The disc 33 is provided with a groove 32 that matches the fixing nut 27. A magnet that matches the magnetic attraction of the fixing nut 27 is provided at the bottom of the groove 32. The second electric push rod 28 is used to push the fixing nut 27 into the groove 32 of the disc 33. The fixing nut 27 can be attracted by the magnet at the bottom of the groove 32. The groove 32 serves to position the fixing nut 27. The groove 32 is provided with a concave hole that matches the fixing screw 23. The fixing nut 27 is threadably coupled to the fixing screw 23. Both the fixing screw 23 and the fixing nut 27 are high-strength connectors. The second housing 26 is used to position and remove the fixing nut 27. Specifically, by rotating the fixing nut 27, the fixing nut 27 can be screwed onto the fixing screw 23. The second housing 26 is capable of loading the fixing nut 27.

[0048] As a technical optimization solution of the present invention, the positioning clamp mechanism includes a universal corrugated rod 30 that is detachably fixed to the flat plate 19, and a positioning clamp 31 is fixed to one end of the universal corrugated rod 30. The universal corrugated rod 30 can achieve multi-directional angle adjustment, and the positioning clamp 31 is used to position and clamp the U-shaped block 7.

[0049] When the present invention is used, when two cylindrical steel pipe columns are docked, the two sleeves 1 are first respectively placed on the two existing cylindrical steel pipe columns, and the corresponding circular holes 2 are aligned. The cylindrical steel pipe columns and the sleeves 1 are fixedly connected by bolts. That is, the cylindrical steel pipe columns are pre-opened with holes corresponding to the bolts. The two cylindrical steel pipe columns are then docked. At this time, the toothed blocks of the two sleeves 1 are meshed and plugged together, effectively improving the accuracy and work efficiency of the docking. Afterwards, the two sleeves 1 are fixedly connected by plugging and matching the plurality of through holes 4 through a plurality of fixing nuts 27 and fixing screws 23. At this time, the through holes 4 for docking and installing the node plate need to be reserved. When assembling the node plate, the movable plate 5 is first installed. The movable plate 5 is inserted through the gap between the two stop bars 9 and supported by the two stop bars 9 by rotation. The orientation of the rotating block 6 is then adjusted according to the needs. The rotating block 6 can be set at a positive inclination angle of 30 degrees, a negative inclination angle of 30 degrees, and a horizontal setting of 180 degrees. Then, insert the fixing screw 23 into the corresponding notch 8 and connect it with the fixing nut 27 to fix the rotating block 6. After the rotating block 6 is fixed in position, use the rubber block 10 and rubber pad 11 to position the rotating block 6 and also provide a buffering effect. Finally, the U-shaped block 7 can be installed and fixed to the node plate.

[0050] In the above operation, multiple movable plates 5 can be set on the side of the sleeve 1, that is, multiple rotating blocks 6 and corresponding U-shaped blocks 7 are set, and the movable plates 5 can move along the circumference of the side wall of the sleeve 1, thereby driving the corresponding rotating blocks 6 and U-shaped blocks 7 to perform multi-directional adjustment, realizing multi-position setting of the circumferential direction, and the rotating block 6 can be set at a positive inclination angle of 30 degrees, a negative inclination angle of 30 degrees, and a horizontal setting of 180 degrees, further satisfying the multi-directional installation effect.

[0051] The two sleeves 1 can not only realize the docking and fixation of two steel pipe columns, but also realize the assembly of node plates in various orientations, including multi-orientation of the circumference, as well as orientation fixation at up and down and horizontal angles.

[0052] At the same time, the rectangular opening of the inner sleeve block 13 of this device can be fitted onto a rectangular steel pipe column. After the inner sleeve block 13 is fitted onto the rectangular steel pipe column, the cylinder 12 and the inner sleeve block 13 can be secured to the rectangular steel pipe column using a number of bolts. In other words, the rectangular steel pipe column is pre-determined with holes corresponding to the bolts, allowing the sleeve 1 to be secured to the rectangular steel pipe column. Furthermore, the rectangular opening of the inner sleeve block 13 can be configured in a variety of sizes, allowing it to be compatible with rectangular steel pipe columns of various sizes. This device can be adapted to and secured to steel pipe columns of various sizes, offering high flexibility.

[0053] At the same time, this device can also assist in the assembly of the fixing screw 23 and the fixing nut 27. That is, the two sleeves 1 are clamped at the opposite ends of the two semicircular ring blocks 15. The two semicircular ring blocks 15 at the upper position are provided with a first box body 22 that can slide precisely, and the two semicircular ring blocks 15 at the lower position are provided with a second box body 26 that can slide precisely. The first box body 22 is used to position and discharge the fixing screw 23, while the second box body 26 is used to position and discharge the fixing nut 27. Specifically, the fixing nut 27 can be rotated to the fixing screw 23. By moving the corresponding electric slider, it can be precisely aligned with the position of several through holes 4 to be installed, thereby setting the fixing screw 23 and the corresponding fixing nut 27, which is convenient for the staff to tighten later, thereby achieving the fixed connection operation of the two sleeves 1. This effectively reduces the time workers spend working at height, improving work efficiency and safety.

[0054] At the same time, through the clamping of the two semicircular ring blocks 15 and the sleeve 1, the two semicircular ring blocks 15 corresponding to the two ends and the components thereon can be stably fixed on the two sleeves 1, and can then achieve the effect of self-movement, that is, the two semicircular ring blocks 15 at the bottom are separated first, and then the rotating motor on the upper mounting frame 14 controls the rotating frame 16 to rotate accurately 180 degrees, so that the connecting rod 17 and the two semicircular ring blocks 15 separated at the bottom are rotated to the top. At this time, the two separated semicircular ring blocks 15 close and clamp the steel pipe column. The two semicircular ring blocks 15 can adapt to clamping the steel pipe column of set specifications. At this time, continue to repeat the above operation, that is, the two semicircular ring blocks 15 at the bottom are separated and rotated to the top, and the effect of continuous movement of the whole on the steel pipe column can be achieved.

[0055] The flat plate 19 located below also fixes a universal corrugated rod 30, which can realize multi-directional angle adjustment, and the positioning fixture 31 at one end of the universal corrugated rod 30 can be used to position and clamp the U-shaped block 7, thereby assisting the assembly and fixation of the U-shaped block 7 and the node plate.

[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
