[0002] Many steel structure factories are equipped with crane beam systems. Crane beams are installed on the columns of the longitudinal walls on both sides of each span of the steel structure factory. Both ends of the crane rails are installed on the crane beams. The crane beams are connected to the main steel structure of the factory through the crane beam auxiliary system structure for reinforcement. The crane beam system is one of the very important load-bearing structures of various industrial factories. It is generally designed as a simply supported structure. The simply supported structure has the advantages of clear force transmission, simple structure and convenient construction.

[0015] 1.

[0017] 3. The present invention sets a trapezoidal platform so that the trapezoidal platform is located on both sides of the bottom end of the target truss column and has a trapezoidal structure, thereby increasing the ground contact area of ​​the bottom end of the target truss column and greatly reducing the risk of the target truss column tipping over during the dragging process. At the same time, the dragging rollers at the bottom of the trapezoidal platform can reduce the friction of the trapezoidal platform and reduce the impact of the installation of the trapezoidal platform on the smoothness of the dragging process;

[0018] 4. The present invention sets a transition track so that after the transition track is installed, when the migration winch drags the target truss column, the trapezoidal platforms on both sides can move inside the transition track, so that the transition track can limit and guide the moving trajectory of the target truss column, thereby preventing the target truss column from deviating from the migration position;

[0019] 5. The present invention provides a U-shaped connecting frame so that the dragging force of the C-shaped telescopic dragging frame on the target truss column is shared by the bottom end of the target truss column and the four trapezoidal platforms at the same time, thereby increasing the integrity of the entire structure during the dragging process and further improving the stability of the migration of the target truss column;

[0020] 6. The present invention sets a stop pin so that when the target truss column is dragged to the top center of the migration embedded plate, the front ends of the two trapezoidal platforms will contact the two stop pins respectively, so that the target truss column cannot move further and stops at the predetermined migration position, thereby realizing automatic braking of the target truss column and avoiding excessive migration of the target truss column and causing position deviation;

[0021] 7. The present invention provides track positioning nails, so that after placing the transition plate or transition track, multiple track positioning nails can be nailed into the concrete hardened ground on both sides of the transition plate. The number of track positioning nails is consistent with the position of the transition track, so that the track positioning nails can limit the transition plate and the transition track, and prevent the position deviation between the transition plate, the transition track and the migration embedded plate and the embedded base plate;

[0022] 8. The present invention sets a temporary support steel frame so that the temporary support steel frame is clamped between the concrete hardened ground and the crane single beam, so that the temporary support steel frame can temporarily support the suspended end of the crane single beam during the migration of the target truss column until the I-shaped steel frame is assembled and then the temporary support steel frame is dismantled to ensure that the internal structure of the crane single beam will not change outside the expected range.

[0036] like Figures 1 to 8 As shown, a column migration structure capable of reinforcing a crane beam comprises a concrete hardened ground surface 1, a plurality of evenly distributed embedded cap plates 2 are buried on the top of the concrete hardened ground surface 1, a plurality of evenly distributed fixed-point truss columns 3 and a target truss column 4 are erected on the top of the concrete hardened ground surface 1, the fixed-point truss columns 3 and the target truss columns 4 are respectively arranged on the top of the plurality of embedded cap plates 2, and a crane single beam 5 arranged in the same horizontal direction is placed on the top of the plurality of fixed-point truss columns 3 and the target truss columns 4, as shown in FIG. Figure 3 As shown, multiple bolt fasteners 6 are fixedly installed between the two ends of the fixed point truss column 3 and the target truss column 4 and the embedded base plate 2 and the crane single beam 5, respectively. Figure 5 , Figure 7 As shown, a migration winch 7 is placed on the top of the concrete hardened ground 1. In this embodiment, depending on the actual situation of the construction site, the migration winch 7 can be replaced with a simpler traction device or tool such as a hand winch. A traction steel strand 8 is wound on the migration winch 7, and a traction hook 9 is fixedly installed on one end of the traction steel strand 8. A dragging assembly is arranged between the traction hook 9 and the target truss column 4. The dragging assembly can make the target truss column 4 migrate while keeping a balanced and stable state at the bottom. The traction hook 9 is connected to the target truss column 4 through the dragging assembly. A migration embedded plate 10 is buried on the top of the concrete hardened ground 1. The migration embedded plate 10 is located between the migration winch 7 and the target truss column 4, as shown in FIG. Figure 8 As shown, a transition plate 11 is placed on the top of the concrete hardened ground 1, and the transition plate 11 is located between the migration embedded plate 10 and the target truss column 4. Figure 4As shown, an inclined I-shaped steel frame 12 is provided between the target truss column 4 and the crane single beam 5; specifically, when the target truss column 4 is to be relocated, the final relocation position of the target truss column 4 is first selected, a pre-buried pit is dug at the relocation position, and the relocation pre-buried plate 10 is buried in the pre-buried pit for fixing, and a new assembly hole is opened at the corresponding position at the bottom of the crane single beam 5, and the transition plate 11 is placed between the relocation pre-buried plate 10 and the original pre-buried cap plate 2, and a leather hammer is used to knock. The transition plate 11 is tightly stuck between the two and eliminates the height difference between the transition plate 11 and the migration embedded plate 10 and the embedded cap plate 2. Then the migration winch 7 is fixed on the concrete hardened ground 1, the towing assembly is assembled at the bottom end of the target truss column 4, the towing hook 9 is hung on the towing assembly, and then the bolt fasteners 6 at the upper and lower ends of the target truss column 4 are removed to release the assembly relationship between the target truss column 4 and the embedded cap plate 2 and the crane single beam 5. The transfer winch 7 can reel in the traction strand 8, and then drag the target truss column 4 through the traction hook 9, so that the target truss column 4 moves on the embedded cap plate 2, and moves to the transfer embedded plate 10 through the transition plate 11 and stops. At this time, two sets of bolt fasteners 6 are used to re-assemble and fix the upper and lower ends of the target truss column 4 with the crane single beam 5 and the transfer embedded plate 10, and one side of the target truss column 4 and the suspended end of the crane single beam 5 are welded, screwed, etc. The I-shaped steel frame 12 is fixedly installed in a certain manner so that the I-shaped steel frame 12 plays the role of a diagonal reinforcement structure. Finally, the transition plate 11 and the migration winch 7 are removed to complete the migration of the target truss column 4, so that the truss column of the crane beam system can be quickly, conveniently and safely migrated. At the same time, the I-shaped steel frame 12 is used to strengthen one end of the crane beam suspended after losing the truss support, thereby reducing the impact of the truss migration on the overall structure of the crane beam, and ensuring that the crane beam still has sufficient structural strength after the truss migration.

[0037] like Figure 6 As shown, the towing assembly includes a towing plate 13 disposed between the target truss column 4 and the towing hook 9, as shown in FIG. Figure 7As shown, a C-shaped telescopic towing frame 14 is fixedly installed on the side of the towing plate 13 facing the target truss column 4, and the towing plate 13 and the C-shaped telescopic towing frame 14 are jointly sleeved on the bottom end of the target truss column 4. In the present embodiment, the C-shaped telescopic towing frame 14 is a C-shaped bidirectional telescopic steel frame, and the two telescopic ends of the C-shaped telescopic towing frame 14 are symmetrical to each other, and a telescopic slide groove is provided inside the end where the two telescopic ends are close to each other, and the same inner slide plate is slidably installed inside the two telescopic slide grooves, and the towing plate 13 and the C-shaped telescopic towing frame 14 are assembled and fixed by bolts, so that the towing plate 13 and the C-shaped telescopic towing frame 14 are fixedly sleeved on the bottom end of the target truss column 4, and a four-rope traction structure 15 is fixedly installed on the side of the towing plate 13 away from the target truss column 4, and a traction ring 16 is fixedly installed on the end of the four-rope traction structure 15 away from the towing plate 13, and the traction ring 16 is mutually clamped with the traction hook 9; specifically, by setting The towing assembly is installed by first stretching the C-shaped telescopic towing frame 14 so that the distance between the two ends of the opening is greater than the width of the target truss column 4, and then the C-shaped telescopic towing frame 14 is sleeved on the target truss column 4, and then the C-shaped telescopic towing frame 14 is retracted to its original state. At this time, the towing plate 13 is screwed and fixed to the C-shaped telescopic towing frame 14 by bolts, so that the towing plate 13 and the C-shaped telescopic towing frame 14 are locked and sleeved on the bottom end of the target truss column 4, and then the towing hook 9 is pulled. By being mutually engaged with the traction ring 16, when the migration winch 7 drags the target truss column 4 through the traction steel strand 8 and the traction hook 9, the traction force will be shared at the four corners of the towing plate 13 through the four-rope traction structure 15, and then act on the bottom end of the target truss column 4 through the C-shaped telescopic towing frame 14, thereby increasing the force-bearing area of ​​the target truss column 4 and fixing the position of the force-bearing point of the target truss column 4, thereby ensuring that the force on the target truss column 4 is stable during the towing process.

[0038] like Figure 7As shown, two trapezoidal platforms 17 are provided on the bottom end of the target truss column 4 facing and away from the dragging plate 13, the dragging plate 13 is located on the top of the two trapezoidal platforms 17, and a C-shaped binding plate 18 is fixedly installed on one side of the trapezoidal platform 17. The trapezoidal platform 17 and the C-shaped binding plate 18 located at the same place are fixedly sleeved on the bottom end of the target truss column 4, and a plurality of evenly distributed drag rollers 19 are rotatably installed on the bottom of the trapezoidal platform 17. In this embodiment, taking the common I-type steel frame 12-type truss column on the market as an example, there are four column legs at the upper and lower ends of the fixed truss column 3 and the target truss column 4, and the trapezoidal platform 17 and the C-shaped binding plate 18 are assembled and fixed by bolts. The trapezoidal platform 17 and the C-shaped binding plate 18 are fixedly sleeved on the four column legs at the bottom end of the target truss column 4; specifically, by setting the trapezoidal platform 17, after the dragging plate 13 is fixed, the four groups of trapezoidal platforms 17 and C-shaped binding plates 18 are respectively fixed and assembled on the four column legs at the bottom end of the target truss column 4 by bolts, so that the trapezoidal platform 17 is located on both sides of the bottom end of the target truss column 4 in a trapezoidal structure, thereby increasing the ground contact area of ​​the bottom end of the target truss column 4 and greatly reducing the risk of rollover of the target truss column 4 during the dragging process. At the same time, the dragging roller 19 at the bottom of the trapezoidal platform 17 can reduce the friction of the trapezoidal platform 17 and reduce the influence of the installation of the trapezoidal platform 17 on the smoothness of the dragging process.

[0039] like Figure 8 As shown, a plurality of transition rails 20 connected to each other are placed on the top of the transition plate 11, and the plurality of transition rails 20 correspond to the positions of the four trapezoidal platforms 17. In this embodiment, the thickness of the transition plate 11 can be selected according to actual needs. When the transition rail 20 is not used, the thickness of the transition plate 11 is the height of the embedded base plate 2 and the migration embedded plate 10 above the ground. If the transition rail 20 is used, the thickness of the bottom of the transition rail 20 plus the thickness of the transition plate 11 is the height of the embedded base plate 2 and the migration embedded plate 10 above the ground. Specifically, by setting the transition rail 20, if the transition rail 20 is needed, a thinner transition rail 20 can be selected. A transition plate 11 is provided, and a plurality of transition tracks 20 connected to each other are placed on the top of the transition plate 11, so that the overall length of the transition track 20 is equal to the transition plate 11, and the overall thickness of the transition track 20 and the transition plate 11 is equal to the height of the ground surface of the migration embedded plate 10, and then the transition track 20 is knocked with a leather hammer to eliminate the height difference between the transition track 20 and the migration embedded plate 10 and the embedded base plate 2. When the migration winch 7 drags the target truss column 4, the trapezoidal platforms 17 on both sides can move inside the transition track 20, so that the transition track 20 has a role of limiting and guiding the moving trajectory of the target truss column 4, thereby preventing the target truss column 4 from deviating from the migration position.

[0040] like Figure 7As shown, U-shaped connecting frames 21 are fixedly installed on the two side surfaces adjacent to the towing plate 13 of the C-shaped telescopic towing frame 14, and the bottom ends of the U-shaped connecting frames 21 located at the same place are fixedly installed on one side of the two trapezoidal platforms 17. In this embodiment, assembly holes are opened on both sides of the bottom of the U-shaped connecting frame 21, so that the two bottom corners of the U-shaped connecting frame 21 are fastened to the trapezoidal platform 17 and the C-shaped binding plate 18 by the same bolts; specifically, by setting the U-shaped connecting frame 21, when assembling the trapezoidal platform 17 and the C-shaped binding plate 18, the trapezoidal platform 17 and the C-shaped binding plate 18 are first The U-shaped connecting frames 21 on both sides of the C-shaped telescopic dragging frame 14 will be located on one side of the trapezoidal platform 17, and the assembly holes at the two corners of the bottom of the U-shaped connecting frame 21 will correspond to the assembly holes on the trapezoidal platforms 17 and the C-shaped binding plate 18 on both sides. At this time, the bolts are directly screwed in for tightening, so that the dragging force of the C-shaped telescopic dragging frame 14 on the target truss column 4 will be shared by the bottom end of the target truss column 4 and the four trapezoidal platforms 17 at the same time, thereby increasing the integrity of the entire structure during the dragging process and further improving the stability of the migration of the target truss column 4.

[0041] like Figure 5 As shown, two end nails 23 are fixedly inserted on the top of the concrete hardened ground 1, and the end nails 23 are located between the migration winch 7 and the migration embedded plate 10, and the positions of the two end nails 23 correspond to the positions of the four trapezoidal platforms 17 respectively; specifically, by setting the end nails 23, the distance between the end nails 23 and the migration embedded plate 10 is equal to the distance between the front end of the trapezoidal platform 17 and the embedded base plate 2. Therefore, when the target truss column 4 is dragged to the top center of the migration embedded plate 10, the front ends of the two trapezoidal platforms 17 will contact the two end nails 23 respectively, so that the target truss column 4 cannot continue to move and stops at the predetermined migration position, thereby realizing automatic braking of the target truss column 4 and avoiding excessive migration of the target truss column 4 and causing position displacement.

[0042] like Figure 8 As shown, a plurality of evenly distributed track positioning nails 22 are fixedly inserted on the top of the concrete hardened ground surface 1, and the plurality of track positioning nails 22 are distributed on both sides of the transition plate 11 and respectively correspond to the positions of the plurality of transition rails 20; specifically, by setting the track positioning nails 22, after placing the transition plate 11 or the transition rail 20, a plurality of track positioning nails 22 can be nailed into the concrete hardened ground surface 1 on both sides of the transition plate 11, and the number of the track positioning nails 22 is consistent with the position of the transition rail 20, so that the track positioning nails 22 can play a limiting role on the transition plate 11 and the transition rail 20, thereby preventing the position deviation between the transition plate 11, the transition rail 20 and the migration embedded plate 10 and the embedded base plate 2.

[0043] like Figure 1 , Figure 2 As shown, a temporary support steel frame 24 is erected on the top of the concrete hardened ground 1, and the temporary support steel frame 24 is located on the side of the target truss column 4 away from the multiple fixed-point truss columns 3 and at the bottom of one end of the crane single beam 5; specifically, by setting the temporary support steel frame 24, before the target truss column 4 is moved, a temporary support steel frame 24 with a length equal to the height of the crane single beam 5 from the ground can be selected, and pushed between one end of the crane single beam 5 and the concrete hardened ground 1 to make it stand vertically, and then a leather hammer is used to knock the temporary support steel frame 24 to clamp it between the concrete hardened ground 1 and the crane single beam 5, so that the temporary support steel frame 24 temporarily supports the suspended end of the crane single beam 5 during the migration of the target truss column 4, until the temporary support steel frame 24 is removed after the I-shaped steel frame 12 is assembled, to ensure that the internal structure of the crane single beam 5 will not change outside the expected range.

[0044] In summary: before migration: first select the location where the target truss column 4 will be finally migrated, dig a pre-buried pit at the migration location, bury the migration embedded plate 10 into the pre-buried pit for fixing, and open a new assembly hole at the corresponding position at the bottom of the crane single beam 5, place the transition plate 11 between the migration embedded plate 10 and the original embedded cap plate 2, use a leather hammer to knock the transition plate 11 so that the transition plate 11 is tightly stuck between the two and eliminate the height difference between the transition plate 11 and the migration embedded plate 10 and the embedded cap plate 2, then fix the migration winch 7 on the concrete hardened ground 1, and connect the towing plate 13 and the C-shaped telescopic towing frame 14 to the bottom end of the target truss column 4 through bolts, and then clamp the towing hook 9 and the towing ring 16 to each other, and first connect the four sets of trapezoidal platforms 17 and the C-shaped binding plate 18 to the four column legs of the target truss column 4, and the U-shaped connecting frames 21 on both sides of the C-shaped telescopic towing frame 14 will Located on one side of the trapezoidal platform 17, the assembly holes at the two corners of the bottom of the U-shaped connecting frame 21 will correspond to the assembly holes on the trapezoidal platforms 17 and the C-shaped binding plates 18 on both sides. At this time, the bolts are directly screwed in for tightening, and then the end nails 23 are nailed into the concrete hardened ground 1 between the migration winch 7 and the migration embedded plate 10, so that the distance between the end nails 23 and the migration embedded plate 10 is equal to the distance between the front end of the trapezoidal platform 17 and the embedded cap plate 2, and then a temporary support steel frame 24 with a length equal to the height of the crane single beam 5 from the ground is selected, and pushed between one end of the crane single beam 5 and the concrete hardened ground 1 to make it stand vertically, and then a leather hammer is used to knock so that the temporary support steel frame 24 is clamped between the concrete hardened ground 1 and the crane single beam 5, and finally the bolt fasteners 6 at the upper and lower ends of the target truss column 4 are removed to release the assembly relationship between the target truss column 4 and the embedded cap plate 2 and the crane single beam 5;

[0045] Among them, if it is necessary to use the transition track 20, a thinner transition plate 11 can be selected, and a plurality of transition tracks 20 spliced ​​to each other can be placed on the top of the transition plate 11, so that the overall length of the transition track 20 is equal to the transition plate 11, and the overall thickness of the transition track 20 and the transition plate 11 is equal to the height of the ground surface of the migration embedded plate 10, and then the transition track 20 is knocked with a leather hammer to eliminate the height difference between the transition track 20 and the migration embedded plate 10 and the embedded base plate 2. When the migration winch 7 drags the target truss column 4, the trapezoidal platforms 17 on both sides can move inside the transition track 20, so that the transition track 20 has a limiting and guiding effect on the moving trajectory of the target truss column 4. After placing the transition plate 11 or the transition track 20, a plurality of track positioning nails 22 can be nailed into the concrete hardened ground 1 on both sides of the transition plate 11. The number of the track positioning nails 22 is consistent with the position of the transition track 20, so that the track positioning nails 22 can play a limiting role on the transition plate 11 and the transition track 20.

[0046] During migration: the migration winch 7 winds up the traction steel strand 8, and then drags the target truss column 4 through the traction hook 9, so that the target truss column 4 moves on the embedded cap plate 2, and moves to the migration embedded plate 10 through the transition plate 11. When the target truss column 4 is dragged to the top center of the migration embedded plate 10, the front ends of the two trapezoidal platforms 17 will contact the two end nails 23 respectively, so that the target truss column 4 cannot continue to move and stops at the predetermined migration position;

[0047] After the migration: use two sets of bolt fasteners 6 to re-assemble and fix the upper and lower ends of the target truss column 4 with the crane single beam 5 and the migration embedded plate 10, and fix the I-shaped steel frame 12 between one side of the target truss column 4 and the suspended end of the crane single beam 5 by welding, screwing, etc., so that the I-shaped steel frame 12 plays the role of a diagonal reinforcement structure, and finally remove the transition plate 11 and the migration winch 7 and other structural components to complete the migration of the target truss column 4.
