In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.

[0037] Reference Appendix Figure 1-4A box-type column assembly device for obliquely joined brackets includes the following structure: guide rail 1, transfer device one 2, transfer device two 3, displacement sensor A4, displacement sensor B5, displacement sensor C6, displacement sensor D7, displacement sensor E8, PLC controller 9, limit component one 10, limit component two 11, and limit component three 12. Transfer device one 2, transfer device two 3, displacement sensor A4, displacement sensor B5, displacement sensor C6, displacement sensor D7, and displacement sensor E8 are all electrically connected to the PLC controller 9.

[0038] Along its length, the guide rail 1 has a first end and a second end. A limiting member 10 is located at the first end of the guide rail 1 to limit the long end of the box-shaped column. A transfer device 2 is movably mounted on the guide rail 1 to support the box-shaped column and is controlled by the PLC controller 9 to translate the box-shaped column along the guide rail 1. Displacement sensors A4 and B5 are located on the transfer device 2 to measure the height of the box-shaped column on the transfer device 2 and the distance between the transfer device 2 and the first end of the guide rail 1, respectively. A limiting member 11 is located on the transfer device 2 and abuts against the side of the box-shaped column. The transfer device 2 3 is located on both sides of the box-shaped column and is movably connected to the guide rail 1 to support the bracket; the PLC controller 9 can control the transfer device 2 3 to translate the bracket along the guide rail 1 or rotate the bracket to change the angle between the bracket and the box-shaped column; displacement sensors C6, D7 and E8 are located on the transfer device 2 3. Displacement sensor C6 is used to measure the height of the bracket on the transfer device 2 3, displacement sensor D7 is used to measure the distance between the end of the transfer device 2 3 near the box-shaped column and the first end of the guide rail 1, and displacement sensor E8 is used to measure the distance between the end of the transfer device 2 3 away from the box-shaped column and the side of the guide rail 1; the limiting member 3 12 is located on the transfer device 2 3 and abuts against the side of the bracket.

[0039] When assembling the box column and bracket using the above-mentioned device, place the guide rail 1 stably, place the box column on the transfer device 2, and adjust the box column so that its long end is pressed against the limiting member 10 and its side is pressed against the limiting member 21 to ensure accurate assembly. Use the transfer device 2 to adjust the height of the box column to facilitate welding. Place the bracket on the transfer device 3, and adjust the bracket so that its side is pressed against the limiting member 32 to ensure accurate assembly. Use the transfer device 3 to adjust the height, position, and angle of the bracket, and weld and fix the bracket and box column. Adjust the direction of the box column so that the side of the box column without bracket is vertical. Repeat the above operation to weld the remaining brackets.

[0040] By adopting the above technical solution, through the cooperation of various displacement sensors, transfer device 1 2, transfer device 2 3 and PLC controller 9, the relative position and relative angle of the bracket and the box column can be digitally controlled, reducing the difficulty of correction, reducing the correction time and improving the accuracy of the mitered joint.

[0041] Reference Appendix Figure 1 The guide rail 1 includes at least two parallel rails 1-1, the first ends of each rail 1-1 are connected by a fixing member 1-2, and a limiting member 10 is provided on the top of the fixing member 1-2. The shapes of the fixing member 1-2 and the limiting member 10 can be configured according to actual usage requirements, and are not specifically limited here.

[0042] In this embodiment, both the track 1-1 and the fixing member 1-2 are made of steel profiles, which are easy to source and have a flat shape; the limiting member 10 is configured as a plate shape, which can better fit the long end face of the box column.

[0043] The transfer device 2 is distributed in several groups along the length of the guide rail 1, including: frame 2-1, roller 2-2 and lifter 2-3. Displacement sensor B5 is installed on the carrier frame 2-1 to measure the distance between the carrier frame 2-1 and the first end of the guide rail 1, and transmits the distance to the PLC controller 9. Rollers 2-2 are installed inside the guide rail 1, and their number can be configured according to actual usage requirements, but at least one electric wheel is configured. The electric wheel is controlled by the PLC controller 9 to drive the carrier frame 2-1 to move along the length of the guide rail 1 to meet the support stability requirements of box columns of different lengths, or after the box column is placed on the carrier frame 2-1, the box column is translated so that its long end abuts against the limiting member 10. Lifter 2-3 is installed on the top of the carrier frame 2-1. Lifter 2-3 is controlled by the PLC controller 9 to adjust the height of the box column. Displacement sensor A4 is installed on the top of the lifter 2-3 to measure the distance between the bottom surface of the box column and the ground, and transmits the distance to the PLC controller 9 as a reference for subsequent adjustment of the bracket height.

[0044] The shape of the limiting member 2 11 can also be configured according to actual usage requirements, and no specific limitation is made here. In some preferred embodiments, the limiting member 2 11 is configured as a plate shape, which can better fit the side of the box column.

[0045] To stably support the box-shaped columns, at least two lifters 2-3 are installed on the carrier frame 2-1. The lines connecting the lifters 2-3 on each carrier frame 2-1 are not parallel to the guide rail 1. A slide rail 2-1a and a matching slide block 2-4 can also be installed on the top of the carrier frame 2-1. The lifters 2-3 are placed on the slide block 2-4. The distance between the lifters 2-3 can be adjusted manually to meet the stability requirements of box-shaped columns of different widths.

[0046] The transfer device 2 3 is located on both sides of the box-shaped column, and includes: a carrier frame 2 3-1, rollers 2 3-2, rollers 3-3, a lifter 2 3-4, and a vertical rotating shaft 3-5. Displacement sensor D7 is located on carrier frame 2 3-1 and measures the distance between the end of carrier frame 2 3-1 near the box-shaped column and the first end of guide rail 1, transmitting the distance to PLC controller 9 as a reference for the relative position of the bracket and the box-shaped column. Displacement sensor E8 is located on carrier frame 2 3-1 and measures the distance between the end of carrier frame 2 3-1 away from the box-shaped column and the side of guide rail 1, transmitting the distance to PLC controller 9 as a reference for the relative angle between the bracket and the box-shaped column. This is because the maximum value of the distance between the end of carrier frame 2 3-1 away from the box-shaped column and the side of guide rail 1 is fixed. After obtaining the real-time value of the above distance, the built-in program of PLC controller 9 can be used to calculate the degree of inclination of carrier frame 2 3-1 relative to guide rail 1, i.e., the relative angle between the bracket and the box-shaped column.

[0047] Rollers 2 (3-2) are located inside the guide rail 1. Their number can be configured according to actual usage requirements, but at least one electric roller must be included. The electric roller is controlled by the PLC controller 9 to move the carrier 2 (3-1) along the length of the guide rail 1 to adjust the relative position of the bracket and the box column. Each roller 2 (3-2) has a vertical rotating shaft 3-5 at its top, and the carrier 2 (3-1) is rotatably connected to the vertical rotating shaft 3-5. Rollers 3 (3-3) are located outside the guide rail 1. Their number can be configured according to actual usage requirements, but at least one electric roller must be included. The electric roller is controlled by the PLC controller 9 to move the carrier 2 (3-1) horizontally or rotate around the vertical rotating shaft 3-5. When it is necessary to change the relative position of the bracket and the box column, rollers 2 (3-2) and 3 (3-3) are controlled to move synchronously. When it is necessary to change the relative angle between the bracket and the box column, rollers 2 (3-2) are kept stationary while rollers 3 (3-3) move.

[0048] Lifter 2 3-4 is located on top of carrier 2 3-1. Lifter 2 3-4 is controlled by PLC controller 9 to adjust the height of the bracket. Displacement sensor C6 is located at the top of lifter 2 3-4 to measure the distance between the bottom surface of the bracket and the ground and transmit it to PLC controller 9 to ensure the accurate welding height of the bracket on the side of the box column.

[0049] Both the lifting device 1 (2-3) and the lifting device 2 (3-4) mentioned above can be hydraulic lifting devices, which are equipped with an electric control valve 13 and a manual valve 14. The electric control valve 13 is electrically connected to the PLC controller 9, and the manual valve 14 is respectively configured on the carrier 1 (2-1) and the carrier 2 (3-1).

[0050] The shape of the limiting member 3 12 can also be configured according to actual usage requirements, and no specific limitation is made here. In some preferred embodiments, the limiting member 3 12 is configured as a plate shape, which can better fit the side of the bracket.

[0051] The shape of the carrier frame 2 3-1, as well as the number and position of rollers 2 3-2, rollers 3-3, and lifting device 2 3-4, can be configured according to actual usage requirements, and are not specifically limited here. This embodiment exemplifies some feasible solutions; please refer to the appendix. Figure 4 The second frame 3-1 has a first arm 3-1a, a second arm 3-1b and a third arm 3-1c. A vertical shaft 3-5 is rotatably connected to the first arm 3-1a. A second roller 3-2 is arranged at the bottom of the vertical shaft 3-5. A third roller 3-3 is arranged at the bottom of the second arm 3-1b and the third arm 3-1c. A second lifter 3-4 is arranged at the top of the first arm 3-1a, the second arm 3-1b and the third arm 3-1c.

[0052] In the above embodiments, a slide rail 3-1d and a slide block 3-6 adapted to the slide rail 3-1d can also be provided on the top of the carrier 3-1. The lifting device 3-4 is placed on the slide block 3-6. The distance between the lifting devices 3-4 can be adjusted by manual operation to meet the support stability requirements of different sized brackets.

[0053] The method for construction using the assembly device provided in this embodiment includes the following steps:

[0054] Remove debris from the site, ensure the ground is flat and level, and place guide rail 1 stably on the ground;

[0055] According to the structural design drawing, input the specifications of the box column and bracket, the coordinates of the welding point of the bracket on the box column, and the relative angle between the bracket and the box column into the PLC controller 9.

[0056] Based on the length of the box-shaped column, PLC controller 9, with the assistance of displacement sensor B5, controls the movement of transfer device 2 and its even distribution on guide rail 1. Based on the width of the box-shaped column, the worker moves slide block 2-4, causing lifter 2-3 to be evenly distributed on carrier frame 2-1. Based on the thickness of the box-shaped column, PLC controller 9, with the assistance of displacement sensor A4, controls the extension and retraction of lifter 2-3 to move the box-shaped column to a suitable height for the worker's welding operation. When placing the box-shaped column on transfer device 2, its long end should be pressed against the first end of guide rail 1's limiting member 10, and its side should be pressed against the second limiting member 11 on transfer device 2 to ensure accurate initial position. Subsequently, using the position of limiting member 10 as the coordinate origin, the bracket will be moved to the designated welding point on the box-shaped column. The second limiting member 11 is pressed against the side of the box-shaped column to ensure that the length direction of the box-shaped column is parallel to the direction of guide rail 1, facilitating subsequent adjustment and alignment of the bracket and the box-shaped column angle.

[0057] Based on the coordinates of the weld points of the bracket on the box-shaped column and the relative angle between the bracket and the box-shaped column, the PLC controller 9, in cooperation with displacement sensors D7 and E8, controls the movement of transfer device 2 3. The specific movement control principle has been described above and will not be repeated here. The relevant control and calculation programs in the PLC controller 9 are existing technologies well known to those skilled in the art and will not be repeated here either. The worker moves the slide block 2 3-6 according to the size of the bracket to stably support it. Based on the height data of the box-shaped column returned by displacement sensor A4, the PLC controller 9, in cooperation with displacement sensor C6, controls the extension and retraction of the lifting device 2 3-4 to move the bracket to an appropriate height. When the bracket is placed on transfer device 2 3, it should be ensured that the side of the bracket is pressed against the limit piece 3 12 on transfer device 2 3 to ensure that the angle adjustment of the bracket by this device is accurate.

[0058] Align and spot weld the brackets to the box column, then flip the box column so that the side without brackets is vertical. Repeat the above operation to spot weld the remaining brackets. After manually re-checking the alignment to ensure it is correct, perform the final welding and fixing.

[0059] Compared with the prior art, the beneficial effects of the present invention are as follows: through the cooperation of various displacement sensors, transfer device 1 2, transfer device 2 3 and PLC controller 9, the relative position and relative angle of the bracket and the box column are digitally controlled, reducing the difficulty of correction, reducing the correction time and improving the accuracy of the mitered joint.

[0060] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
