Description

Technical Field

[0001] This invention patent relates to the technical field of steel pipe columns. Specifically, it relates to a method for concentric and coaxial butt joint between a steel pipe column and a tool column. Background Art

[0002] In the construction of the top-down method, the steel pipe column is a permanent structure and has extremely high requirements for positioning and verticality control. To meet the high-precision requirements, a full casing full-rotation drilling rig is usually used for positioning. However, since the top elevation of the steel pipe column is generally below the ground level, during the construction process, it is necessary to connect the tool column to the steel pipe column and use the tool column to assist in positioning.

[0003] Currently, for the on-site butt joint between the top-down steel pipe column and the tool column, an I-beam erection positioning platform is mostly used. This platform consists of multiple I-beam frames. During the butt joint, it is necessary to repeatedly adjust the bolt holes of the flange structures of the steel pipe column and the tool column with the help of a crane, and manual padding is also required repeatedly during the butt joint process to complete the butt joint.

[0004] In the prior art, the butt joint between the steel pipe column and the tool column mainly relies on manually adjusting the alignment of the bolt holes. In addition, there is no motor-driven active support wheel to drive the steel pipe column to rotate on its axis. Instead, it relies on manual adjustment and padding. Under the difficult-to-control human operation errors and the limitations of equipment accuracy, high-precision concentric and coaxial butt joint cannot be achieved. For example, during the butt joint process, it is necessary to repeatedly use a crane to adjust the positions of the steel pipe column and the tool column. This manual operation method not only has low efficiency but also is prone to errors and is difficult to ensure the butt joint accuracy. Summary of the Invention

[0045] Refer to Figures 1-6 As shown, it is a preferred embodiment provided by the present invention.

[0046] The concentric and coaxial docking method for the steel pipe column and the tool column includes the following docking steps:

[0047] 1), Docking and arranging the docking site 100 at the docking site 100, and the flatness of the docking site 100 meets the set requirements;

[0048] 2), the docking site 100 has an adjacent steel pipe column area and a tool column area. A plurality of actively arranged roller stands 200 are arranged at intervals in the steel pipe column area, and a plurality of passively arranged roller stands 300 are arranged at intervals in the tool column area; the plurality of actively arranged roller stands 200 and the plurality of passively arranged roller stands 300 are arranged at intervals in sequence, and the actively arranged roller stands 200 and the passively arranged roller stands 300 are arranged at the same height;

[0049] The actively arranged roller stand 200 includes two actively arranged frames 201 facing each other. An active area 202 for the steel pipe column 101 to be inserted into is formed between the two actively arranged frames 201; an actively supported wheel 203 that supports the steel pipe column 101 from bottom to top is provided on the actively arranged frame 201, and the actively supported wheel 203 is connected to a motor 204;

[0050] The passively arranged roller stand 300 includes two passively arranged frames 301 facing each other. A passive area 302 for the tool column 102 to be inserted into is formed between the two passively arranged frames 301; a passively supported wheel 303 that supports the tool column 102 from bottom to top is provided on the passively arranged frame 301;

[0051] 3), place the tool column 102 on the plurality of passively arranged roller stands 300, and the lower part of the tool column 102 is inserted into the plurality of passive areas 302; place the steel pipe column 101 on the plurality of actively arranged roller stands 200, and the lower part of the steel pipe column 101 is inserted into the plurality of active areas 202, and the steel pipe column 101 and the tool column 102 are arranged coaxially and facing each other;

[0052] The end of the steel pipe column 101 has a docking flange, and the end of the tool column 102 has a docking end 103. The docking flange and the docking end 103 are abutted against each other; the docking flange has a steel pipe through hole, and the docking end 103 has a tool through hole;

[0053] 4), the motor 204 drives the actively supported wheel 203 to rotate, and the actively supported wheel 203 drives the steel pipe column 101 to rotate around a fixed axis until the steel pipe through hole of the docking flange is aligned and communicated with the tool through hole of the tool column 102;

[0054] 5), use bolts to pass through the steel pipe through hole and the tool through hole for fixed connection, so that the docking flange and the docking end 103 are fixedly docked into one body, and the steel pipe column 101 and the tool column 102 are fixedly docked to form a steel structure column.

[0055] The above-mentioned method for concentric and coaxial docking of the steel pipe column 101 and the tool column 102, through the equal-height arrangement and sequential interval setting of the actively arranged roller stand 200 and the passively arranged roller stand 300, enables the steel pipe column 101 and the tool column 102 to be arranged coaxially and facing each other, providing a prerequisite for high-precision docking;

[0056] Furthermore, the motor 204 drives the active support wheel 203 to drive the steel pipe column 101 to rotate around a fixed axis until the steel pipe through-hole of the steel pipe column 101 is aligned and communicated with the tool through-hole of the tool column 102. This process not only improves the construction efficiency but also realizes the high-precision docking of the steel pipe column 101 and the tool column 102.

[0057] In addition, by arranging the active roller rack 200 and the driven roller rack 300 that meet the flatness requirements at the docking site 100, a stable support foundation is provided for the steel pipe column 101 and the tool column 102, effectively reducing the shaking and offset during the docking process and ensuring the smooth progress of the docking process; and by using the method of fixed connection with bolts, the steel pipe column 101 and the tool column 102 are firmly docked into one body to form a stable steel pipe structural column, which also ensures the integrity and reliability of the structure.

[0058] In this embodiment, in docking step 5), after the docking flange is fixedly docked with the docking end 103 as a whole, the verticality of the steel pipe structural column is detected. When the verticality of the steel pipe structural column meets the set verticality, the docking flange and the docking end 103 are welded and fixed.

[0059] By detecting the verticality of the steel pipe structural column and the method of secondary fixation, the overall stability of the steel pipe structural column after docking can be ensured, avoiding potential structural safety hazards caused by verticality deviation, thereby improving the construction quality.

[0060] In this embodiment, in docking step 5), when the verticality of the steel pipe structural column deviates from the set verticality, after the bolts are disengaged from the steel pipe through-hole and the tool through-hole, docking steps 4) and 5) are repeated until the verticality of the steel pipe structural column meets the set verticality.

[0061] Such an operation process reflects the flexibility and reliability of the concentric and coaxial docking method of the steel pipe column 101 and the tool column 102. By repeating the adjustment until the requirements are met, the precise docking and verticality requirements of the steel pipe column 101 and the tool column 102 are ensured.

[0062] In this embodiment, in docking step 1), the sundries on the docking site 100 are cleared, and concrete is poured on the docking site 100. After the concrete solidifies, the docking site 100 is formed.

[0063] In this way, it can be ensured that the docking site 100 has sufficient flatness and bearing capacity, providing a basic guarantee for subsequent high-precision docking and reducing the docking error caused by uneven site.

[0064] In this embodiment, in docking step 2), the driven support wheel 303 is arranged at the lower part of the driven frame 301, and a driven side wheel 304 is arranged at the upper part of the driven frame 301; in docking step 3), after the lower part of the tool column 102 is embedded in the driven area 302, the driven side wheel 304 abuts against the tool column 102 laterally.

[0065] By arranging the driven side wheel 304, the position of the tool column 102 can be further stabilized, the shaking during the docking process can be reduced, and thus the stability of the docking process can be improved.

[0066] In this embodiment, in docking step 2), the driving support wheel 203 is arranged at the lower part of the driving frame 201, and a driving side wheel 205 is arranged at the upper part of the driving frame 201; in docking step 3), after the lower part of the tool column 102 is embedded in the driving area 202, the driving side wheel 205 abuts against the steel pipe column 101 laterally.

[0067] By arranging the driving side wheel 205, the lateral displacement of the steel pipe column 101 can be effectively restricted, the stability of the steel pipe column 101 on the driving roller rack 200 can be ensured, and a strong guarantee is provided for accurate docking.

[0068] In this embodiment, in docking step 2), a plurality of bases 104 are arranged at intervals in sequence in the steel pipe column area and the tool column area respectively. The plurality of bases 104 are arranged at the same height, and the driving roller rack and the driven roller rack 300 are respectively fixed on the bases 104.

[0069] After the base 104 is placed in place, the driving roller rack 200 and the driven roller rack 300 are placed on the base 104. The driven roller rack 300 is arranged under the tool column 102, and two driving roller racks 200 are arranged under the steel pipe column 101, and a driven roller rack 300 is spaced between the two driving roller racks 200.

[0070] In this way, the stability of the driving roller rack 200 and the driven roller rack 300 can be ensured. At the same time, the coaxial docking accuracy of the steel pipe column 101 and the tool column 102 is ensured by the arrangement at the same height, and the docking quality is further improved.

[0071] In this embodiment, in docking step 2), the base 104 includes two lower layers 105 arranged at intervals facing each other. There is a lower layer interval 106 between the two lower layers 105; a plurality of upper layers 107 are arranged between the two lower layers 105. The upper layer 107 spans across the lower layer interval 106, and both ends of the upper layer 107 respectively abut against the two lower layers 105. The plurality of upper layers 107 are arranged at intervals along the length direction of the lower layer 105;

[0072] The lower layer racks 105 are fixedly connected to the docking site 100. Multiple lower layer racks 105 are welded into one body with multiple upper layer racks 107. A steel plate 108 is connected to the multiple upper layer racks 107, and the steel plate 108 connects the multiple upper layer racks 107 into one body; the driven roller rack 300 and the driving roller rack 200 are respectively fixedly connected to the upper layer rack 107.

[0073] Through the multi-layer spaced arrangement of the base 104, not only the overall stability of the base 104 is enhanced, but also the rigidity of the structure is further improved by means of welding and connection with the steel plate 108, providing a reliable support for high-precision docking.

[0074] In this embodiment, in docking step 2), two telescopic shafts 400 arranged longitudinally at intervals are provided between the two driving roller racks 200. The top of the telescopic shaft 400 has rolling balls 401 arranged in a rolling manner; in docking step 3), after the lower part of the steel pipe column 101 is embedded in the active area 202, the rolling balls 401 of the two telescopic shafts 400 abut against the lower part of the steel pipe column 101 from bottom to top, and the telescopic shafts 400 are in a compressed state;

[0075] In construction step 4), during the process of the driving support wheel 203 driving the steel pipe column 101 to rotate around a fixed axis, the rolling balls 401 rotate synchronously in place as the steel pipe column 101 rotates.

[0076] By providing the rolling balls 401 and the telescopic shafts 400, stable support can be provided during the rotation of the steel pipe column 101, reducing friction. At the same time, the compressed state of the telescopic shafts 400 can adapt to the small displacement of the steel pipe column 101, further improving the stability and accuracy of the docking process.

[0077] In this embodiment, in construction step 2), a groove ring 402 is formed on the outer periphery of the driving support wheel 203. The groove ring 402 is arranged circumferentially around the driving support wheel 203, and the driving support wheel 203 has abutting rings 403 located on both sides of the groove ring 402;

[0078] An elastic ring 404 is filled in the groove ring 402. The middle part of the elastic ring 404 is fixedly connected to the groove ring 402; the lower part of the elastic ring 404 is movably placed in the groove ring 402 to form a lower section 407. There is a deformation interval 405 between the lower section 407 and the inner side wall of the groove ring 402; the upper part of the elastic ring 404 extends outside the groove ring 402 to form an upper section 406;

[0079] In docking step 3), after the steel pipe column 101 is placed in the active area 202, the steel pipe column 101 presses against the upper section 406 from top to bottom. The upper section 406 and the lower section 407 are compressed into the groove ring 402. The upper section 406 abuts against the steel pipe column 101, and the two abutting rings 403 synchronously abut against the steel pipe column 101.

[0080] In construction step 4), during the process that the driving support wheel 203 drives the steel pipe column 101 to rotate around a fixed axis, the two abutting rings 403 rigidly drive the steel pipe column 101 to rotate around a fixed axis, and the elastic ring 404 elastically drives the steel pipe column 101 to rotate around a fixed axis.

[0081] In this way, it can ensure that the steel pipe column 101 has rigid support during the rotation process and can adapt to small displacements through the elastic deformation of the elastic ring 404, thereby further improving the docking accuracy and stability.

[0082] In this embodiment, the rollers of the driving roller frame 200 and the driven roller frame 300 are made of a structure with an inner iron core and an outer rubber. The operation of the driving roller frame 200 is synchronously driven by the motor 204 through a worm gear reduction box, and stepless speed regulation is achieved by using a speed control controller, which has an expanded unfolding function, that is, within a specified range, the swing angle of the driving roller frame can be automatically adjusted according to the diameters of the steel pipe column 101 and the tool column 102, and it is suitable for the steel pipe column 101 and the tool column 102 with diameters in the range of 600 mm to 3800 mm. In this way, the driving roller frame 200 has better construction adaptability in the actual construction environment, thereby improving the construction efficiency.

[0083] In this embodiment, the driving roller frame 200 connected to the motor 204 has a self-rotation function. After the steel pipe column 101 and the tool column 102 are hoisted in place, the column body contacts the rollers of the driving roller frame 200 and the driven roller frame 300. The rollers are wrapped with rubber and have a large friction force. When the motor 204 of the driving roller frame 200 is started, the rollers can slowly rotate at a constant speed and drive the steel pipe column 101 to rotate around its central axis, ensuring that the steel pipe column 101 rotates smoothly in a small amplitude around a fixed axis.

[0084] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
