[0024] It should be noted that the lower bracket 11 and the lower adjustment plate 12 of the U-shaped structure can be combined into a closed frame structure, which can be fixedly constrained on the large steel structure to avoid separation from the large steel structure during the correction process. It also provides a four-sided foundation for the movable bracket 2, allowing it to set the straightening correction mechanism 4 from four sides to enhance the straightening correction effect.

[0025] The first driver 13 is a cylinder, which can be connected to the movable bracket 2 at the top to control the movement of the movable bracket 2 so that the movable bracket 2 can drive the straightening mechanism 4 to correct the curved area.

[0026] The adjustment structure 14 is arranged on the lower bracket 11 and connected to the lower adjustment plate 12. It can drive the lower adjustment plate 12 to move and control the opening area of ​​the lower bracket 11 to open, making it convenient to install the device on a large steel structure.

[0027] The movable bracket 2 is arranged above the fixed bracket 1 , and the movable bracket 2 includes an upper bracket 21 , an upper adjustment plate 22 and a plurality of guide plates 23 .

[0028] Among them, the upper bracket 21 is a U-shaped structure, the upper bracket 21 is arranged above the lower bracket 11, the upper adjustment plate 22 is located above the lower adjustment plate 12, the top ends of the four groups of first drivers 13 are respectively connected to the upper bracket 21 and the upper adjustment plate 22, and multiple guide plates 23 are respectively arranged on the upper adjustment plate 22, and the guide plates 23 are plugged into the upper bracket 21.

[0029] It should be noted that the upper bracket 21 and the lower bracket 11 have matching structures and the same functions, and the upper adjustment plate 22 and the lower adjustment plate 12 have matching structures and the same functions. At the same time, the lower bracket 11 is connected to the upper bracket 21 through the first driver 13, and the lower adjustment plate 12 is connected to the upper adjustment plate 22 through the first driver 13. Through the connection of this structure, when the lower adjustment plate 12 moves, it can drive the upper adjustment plate 22 to follow the movement. Multiple guide plates 23 are plugged into the upper bracket 21 to provide stable support for the movement of the upper adjustment plate 22.

[0030] Two sets of fixing mechanisms 3 are arranged on the lower support 11 and the lower adjusting plate 12 respectively.

[0031] It should be noted that the fixing mechanisms 3 are arranged on the lower support 11 and the lower adjusting plate 12 respectively, and when the lower support 11 is sleeved on the large steel structure and the lower adjusting plate 12 is closed to the lower support 11, the fixing mechanisms 3 extrude the surface of the large steel structure to realize the fixing effect of the device.

[0032] The straightening mechanism 4 is arranged above the fixing mechanisms 3 and connected with the upper support 21 and the upper adjusting plate 22 respectively.

[0033] It should be noted that the straightening mechanism 4 is connected with the upper support 21 and the upper adjusting plate 22 and supported by the two, and the straightening mechanism 4 is extruded on the bent area of the steel pipe of the large steel structure, and through the driving of the first driver 13 at the bottom, the straightening mechanism 4 is roll-pressed on the bent area of the steel pipe of the large steel structure to realize the straightening function.

[0034] The heating softener 5 is inserted and arranged on the upper support 21 and located below the straightening mechanism 4.

[0035] It can be understood that the heating softener 5 can contact the surface of the steel pipe area of the large steel structure and perform high-temperature heating to soften the steel pipe area, so that the straightening mechanism 4 can be roll-pressed and corrected.

[0036] Specifically, the relevant staff directly sleeves the lower support 11 and the upper support 21 on the steel pipe area of the large steel structure, controls the lower adjusting plate 12 and the upper adjusting plate 22 to be movable through the operation of the adjusting structure 14, positions the steel pipe area of the large steel structure in the lower support 11 and the upper support 21, and completes the fixing of the device through the extrusion of the fixing mechanisms 3.

[0037] The first driver 13 is operated to control the upper support 21 and the upper adjusting plate 22 to change the position, so that the heating softener 5 is attached to the bent area of the large steel structure, the heating softener 5 is operated to perform high-temperature softening on the area, the first driver 13 is operated to control the upper support 21 and the upper adjusting plate 22 to be movable after the softening is completed, the straightening mechanism 4 is roll-pressed on the bent area, and the large steel structure is straightened and corrected.

[0038] In one embodiment of the present application, as shown in Figure 4 The adjusting structure 14 comprises a toothed plate 141, a limiting plate 142, a gear 143 and an outer cover 144.

[0039] Among them, the tooth plate 141 is set on the lower adjustment plate 12 and inserted into the lower bracket 11, the limit plate 142 is set in the lower bracket 11 and inserted into the tooth plate 141, the outer cover 144 is set on one side of the lower bracket 11, and the gear 143 is rotatably set in the outer cover 144 and is engaged with the tooth plate 141.

[0040] It should be noted that a servo motor may be provided on the outer cover 144 , and the servo motor is connected to the gear 143 to drive it.

[0041] It can be understood that the gear 143 is engaged with the tooth plate 141, which can drive the tooth plate 141 to move, and the tooth plate 141 drives the lower adjustment plate 12 to move to realize the adjustment function. The limit plate 142 is plugged into the tooth plate 141 to ensure the stability of the movement of the tooth plate 141, and will not cause deflection and other problems to cause it to disengage from the gear 143, thereby playing a limiting role.

[0042] Specifically, after the relevant staff puts the lower bracket 11 and the upper bracket 21 on the large steel structure, they can run the servo motor to drive the gear 143 to rotate, and the gear 143 drives the gear plate 141 to drive the lower adjustment plate 12 to move. At the same time, the lower adjustment plate 12 drives the upper adjustment plate 22 to follow the movement, forming a frame structure with the lower bracket 11 and the upper bracket 21 to avoid separation from the large steel structure.

[0043] In one embodiment of the present invention, Figure 3 As shown, the fixing mechanism 3 includes a spring 31 , a limiting member 32 and an arc-shaped pressing plate 33 .

[0044] Among them, a fixed cavity is opened on the lower bracket 11 and the lower adjustment plate 12, the spring 31 is arranged in the fixed cavity, the limit member 32 is arranged in the fixed cavity, and is located on one side of the spring 31, and the other end of the limit member 32 extends to the outside of the lower bracket 11 and the lower adjustment plate 12, and the arc-shaped pressure plate 33 is connected to the other end of the limit member 32.

[0045] It can be understood that the cross-section of the limit member 32 is a T-shaped structure, one end of which extends to the outside and is connected to the arc pressure plate 33, and the other end of the limit member 32 is restricted in the fixed cavity and cannot be separated. It is pushed by the reaction force of the spring 31 to achieve the pressing and fixing of the arc pressure plate 33.

[0046] The arc-shaped pressing plate 33 is an arc-shaped structure, which is suitable for fixing square tubes and round tubes.

[0047] Specifically, after the relevant staff completes the adjustment of the lower adjustment plate 12, the arc pressure plate 33 squeezes the steel pipe area of ​​the large steel structure. The extrusion force is transmitted to the spring 31 through the limiter 32. The spring 31 provides a reaction force to push the arc pressure plate 33 to firmly fix the device on the large steel structure.

[0048] In one embodiment of the present invention, Figure 1 and Figure 2 As shown in the figure, the straightening mechanism 4 includes four sets of straightening rollers 41 and four second drivers 42.

[0049] The four second drivers 42 are respectively arranged on the upper support 21 and the upper adjusting plate 22, and the four second drivers 42 are respectively arranged at one end of the corresponding second driver 42.

[0050] It should be noted that the second driver 42 is a hydraulic cylinder, and an oil tank and a delivery pump can be arranged on the upper adjusting plate 22 and the upper support 21 when the hydraulic cylinder is in use. The straightening rollers 41 are pushed against the surface of the softened large steel structure by the pushing force provided by the hydraulic cylinder, and the rolling straightening function is realized by cooperating with the moving force provided by the first driver 13.

[0051] The four second drivers 42 are arranged on three side walls of the upper support 21 and the upper adjusting plate 22, and since the upper support 21 and the upper adjusting plate 22 form a frame structure, the two second drivers 42 in the corresponding direction are flush, the four second drivers 42 are divided into two groups, and the two groups of second drivers 42 are distributed vertically, so that the straightening rollers 41 are also distributed in the same position. This structure can avoid the problem that adjacent straightening rollers 41 may touch and interfere with each other.

[0052] Specifically, the relevant staff operates the second driver 42 to drive the straightening roller 41 to press on the bent position of the softened large steel structure, and operates the first driver 13 to drive the straightening roller 41 to move, so as to roll and straighten the bent area.

[0053] In summary, the large steel structure straightening device can fix the straightening device in the steel pipe area for straightening without disassembling the large steel structure, thereby ensuring the repair effect of the large steel structure.
