[0002] A steel box girder segment refers to a steel box girder that has been divided into multiple independent parts during manufacturing and installation. These parts are called segments. The size and shape of the segments vary depending on the specific bridge design and construction plan. A two-way alignment device for steel box girder segment assembly is required when splicing steel box girder segments.

[0003] Common bidirectional correction devices for segmental assembly of steel box girders still have some problems. For example, manual assistance is required when using such devices, which makes it inconvenient to quickly correct segments, easily affects correction efficiency, and is time-consuming and labor-intensive.

[0004] Therefore, we propose a bidirectional correction device for segmental assembly of steel box girders to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a bidirectional correction device for steel box girder segment assembly, so as to solve the problems mentioned in the background art, which are inconvenient and slow to correct segments, easily affect correction efficiency, and are time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional correction device for segmental assembly of steel box girders, comprising a first mounting base, a fixing plate fixedly connected to the right side of the top of the first mounting base, a guide rail plate fixedly connected to the top of the right side of the fixing plate, a first cylinder mounted at the bottom of the right side of the fixing plate, a movable plate mounted to the right side of the first cylinder, a second mounting base mounted at the bottom of the movable plate, a support frame fixedly connected to the top of the first mounting base, second cylinders mounted at the front and rear ends of the support frame, a connecting plate provided on the side of the second cylinder near the outside, and a correction plate fixedly connected to the bottom of the connecting plate.

[0010] As a further technical solution of this utility model, the slider is respectively disposed inside the limiting groove and the limiting slide groove, and the slider slides inside the limiting groove and the limiting slide groove respectively.

[0011] As a further technical solution of this utility model, the ball rolls inside the groove, and multiple sets of the ball and the groove are respectively provided.

[0012] As a further technical solution of this utility model, a mounting plate is fixedly connected to one end of the second cylinder near the outside. Fixing grooves are respectively opened at the four corners inside the mounting plate and the top of the connecting plate. Fixing bolts are provided inside the fixing grooves, and fixing nuts are provided at the outer end of the fixing bolts near the middle.

[0013] As a further technical solution of this utility model, the mounting plate is fixed to one end of the connecting plate by fixing bolts and fixing grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the bidirectional correction device for steel box girder segment assembly not only facilitates rapid segment correction and improves the stability of correction, but also facilitates the disassembly and assembly of connecting plates.

[0015] (1) By setting a first mounting seat, a first cylinder, a movable plate, a second mounting seat, a correction plate and a second cylinder, the first mounting seat and the second mounting seat are respectively installed on two steel box girder segments. After installation, the first cylinder is started. The first cylinder drives the steel box girder segments to move through the movable plate and the second mounting seat so that the two steel box girder segments are close to the adjusted steel box girder segments. After the steel box girder segments are adjusted, the second cylinder is started. The second cylinder drives the correction plate to move towards the middle through the connecting plate so that the two sets of steel box girder segments are aligned and the two sets of steel box girder segments are not misaligned, so that the steel box girder segments can be further corrected.

[0016] (2) By setting limit grooves, limit slides, sliders, balls and grooves, when the connecting plate and the movable plate move left and right, the slider will slide inside the limit grooves and limit slides respectively, thereby guiding the connecting plate and the movable plate and improving the stability of the movement of the connecting plate and the movable plate. The balls inside the grooves can reduce the wear of the slider.

[0017] (3) By setting fixed bolts, fixed grooves, fixed nuts and mounting plates, the connecting plate is prone to bending and damage over a long period of time. When the connecting plate needs to be disassembled and replaced, the fixed nuts are unscrewed from the outside of the fixed bolts, and then the fixed bolts are unscrewed from the inside of the fixed grooves so that the connecting plate is no longer fixed. Once the connecting plate is no longer fixed, the connecting plate can be disassembled and the movable plate can be replaced to prevent the connecting plate from bending and affecting the correction.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides an embodiment of a bidirectional correction device for segmental assembly of steel box girders, comprising a first mounting base 1, a fixing plate 4 fixedly connected to the right side of the top of the first mounting base 1, a guide rail plate 5 fixedly connected to the top of the right side of the fixing plate 4, a first cylinder 7 installed at the bottom of the right side of the fixing plate 4, a movable plate 8 installed to the right side of the first cylinder 7, a second mounting base 9 installed at the bottom of the movable plate 8, a support frame 3 fixedly connected to the top of the first mounting base 1, a second cylinder 19 installed at both the front and rear ends of the support frame 3, a connecting plate 2 provided on the side of the second cylinder 19 near the outside, and a correction plate 10 fixedly connected to the bottom of the connecting plate 2.

[0025] Two sets of second cylinders 19 are provided. The second cylinders 19 are symmetrically distributed about the vertical center line of the support frame 3. The bottom ends of the first mounting seat 1 and the second mounting seat 9 are on the same horizontal line. The second mounting seat 9 is located on the right side of the first mounting seat 1.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the first mounting base 1 and the second mounting base 9 are respectively installed on the two steel box girder segments. After installation, the first cylinder 7 is started. The first cylinder 7 drives the steel box girder segments to move through the movable plate 8 and the second mounting base 9, so that the two steel box girder segments are close to the adjusted steel box girder segments. After the steel box girder segments are adjusted, the second cylinder 19 is started. The second cylinder 19 drives the correction plate 10 to move towards the middle through the connecting plate 2, so that the two sets of steel box girder segments are aligned and misalignment is prevented, thereby allowing for further correction of the steel box girder segments.

[0027] The top of the movable plate 8 and the connecting plate 2 are respectively fixedly connected to the slider 13. The top of the slider 13 is provided with a rolling groove 17. The rolling groove 17 is provided with a ball 16. The front and rear ends of the top of the support frame 3 are provided with limit grooves 12. The bottom of the guide plate 5 is provided with a limit groove 6. The slider 13 is respectively provided in the limit groove 6 and the limit groove 12. The slider 13 slides in the limit groove 6 and the limit groove 12 respectively. The ball 16 rolls in the rolling groove 17. There are multiple sets of balls 16 and rolling groove 17.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when the connecting plate 2 and the movable plate 8 move left and right, the slider 13 will slide inside the limiting groove 6 and the limiting slide groove 12 respectively, thereby guiding the connecting plate 2 and the movable plate 8 and improving the stability of their movement. The ball bearings 16 inside the rolling groove 17 can reduce the wear of the slider 13.

[0029] The second cylinder 19 is fixedly connected to a mounting plate 18 at one end near the outside. Fixing grooves 14 are respectively provided at the four corners inside the mounting plate 18 and the top of the connecting plate 2. Fixing bolts 11 are provided inside the fixing grooves 14. Fixing nuts 15 are provided at one end of the fixing bolts 11 near the middle. The mounting plate 18 is fixed to one end of the connecting plate 2 by fixing bolts 11 and fixing grooves 14.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, the connecting plate 2 is prone to bending and damage over a long period of time. When the connecting plate 2 needs to be disassembled and replaced, the fixing nut 15 is unscrewed from the outside of the fixing bolt 11, and then the fixing bolt 11 is unscrewed from the inside of the fixing groove 14 to make the connecting plate 2 lose its fixation. Once the connecting plate 2 is not fixed, the connecting plate 2 can be disassembled and the movable plate 8 can be replaced to prevent the connecting plate 2 from bending and affecting the correction.

[0031] Working Principle: This utility model uses a crane to hoist the two sets of steel box girder segments to be installed onto designated supports for rough positioning. After the segments are in place, the first mounting base 1 and the second mounting base 9 are installed on the two segments respectively. After installation, the first cylinder 7 is activated. The first cylinder 7, through the movable plate 8 and the second mounting base 9, moves the steel box girder segments closer together. After adjustment, the second cylinder 19 is activated. The second cylinder 19, through the connecting plate 2, moves the correction plate 10 towards the center, aligning the two sets of steel box girder segments and preventing misalignment. To further correct the steel box girder segments, when the connecting plate 2 and the movable plate 8 move left and right, the slider 13 will slide inside the limiting groove 6 and the limiting slide groove 12 respectively, thereby guiding the connecting plate 2 and the movable plate 8 and improving the stability of their movement. The ball bearings 16 inside the roller groove 17 can reduce the wear of the slider 13. The connecting plate 2 is prone to bending and damage over a long period of time. When the connecting plate 2 needs to be disassembled and replaced, the fixing nut 15 is unscrewed from the outside of the fixing bolt 11, and then the fixing bolt 11 is unscrewed from the inside of the fixing groove 14 to make the connecting plate 2 lose its fixation. Once the connecting plate 2 is not fixed, the connecting plate 2 can be disassembled and the movable plate 8 can be replaced to prevent the connecting plate 2 from bending and affecting the correction.
