[0002] At present, steel box girders have been widely used in bridge engineering. However, in long-span bridge engineering, due to the large width of steel box girders, transportation is difficult and collisions are likely to cause damage. Therefore, it is necessary to disassemble the steel box girder into a steel box girder main body and two steel box girder wing plates to reduce transportation difficulties. During bridge construction, a crane is used to first hoist the steel box girder main body onto the erected temporary pier, and then the two steel box girder wing plates are hoisted onto both sides of the steel box girder main body in sequence for assembly. However, during the assembly process, the steel box girder wing plates need to be accurately hoisted and positioned to complete the assembly with the steel box girder main body and complete the bridge construction.

[0003] In the prior art, there are usually two methods for hoisting and positioning steel box girder wing plates. One is that during hoisting, the crane operator needs to, under the command and cooperation of other workers, move the steel box girder wing plate to a predetermined height by slowly moving the boom and lifting the hoisting cable, and adjust the distance between the steel box girder wing plate and the completed steel box girder main body. Then, the steel box girder main body and the steel box girder wing plate are temporarily welded by welders. The crane positioning time is long, the positioning accuracy is low, which affects the assembly quality and efficiency. It has high technical requirements for the crane operator, high personnel cooperation requirements, and high costs. Moreover, when there is a slope requirement for the assembled steel box girder wing plate, the operation difficulty for the crane operator is large, time-consuming and laborious, and the work efficiency is low. The other is to build a temporary support for supporting the steel box girder wing plate beside the temporary pier. During hoisting, the steel box girder wing plate is hoisted onto the temporary support for assembly with the steel box girder main body. However, it occupies a large area, is easily restricted by the construction site, and has high construction costs and low economic benefits. Content of the Utility Model

[0046] The number of the steel box girder wing plates 12 is two, which are respectively arranged on both sides of the steel box girder main body 11 along the width direction. The connection component 5 is detachably pre-installed on the steel box girder wing plate 12. Before using this embodiment, the crane operator operates the boom 7 to first hoist the steel box girder main body 11 onto the temporary pier 8, and then hoist one of the steel box girder wing plates 12 to the side of the steel box girder main body 11 to be assembled.

After the distance and angle adjustments are completed, the staff uses the welding plate 9 to temporarily fix the wing plate 12 of the steel box girder and the main body 11 of the steel box girder, and carry out the assembly work of the wing plate 12 on the other side.

[0050] In this embodiment, as Figure 2 and Figure 3 shown, by rotating the winding drum 31, the traction rope 32 is wound or unwound to adjust the spacing between the wing plate 12 of the steel box girder and the main body 11 of the steel box girder. During specific work, when the wing plate 12 of the steel box girder is lifted by a crane to the side of the main body 11 of the steel box girder to be assembled, after connecting the hook 33 to the connection component 5, the staff slowly rotates the winding drum 31 to wind the traction rope 32 to pull the wing plate 12 of the steel box girder to move closer to the main body 11 of the steel box girder, so as to fine-tune the spacing between the wing plate 12 of the steel box girder and the main body 11 of the steel box girder, so that the wing plate 12 of the steel box girder is accurately located at the predetermined assembly position. The structure is simple, the operation is convenient, the positioning is accurate, fast, the construction efficiency is high, and manpower is saved.

[0051] As a preferred embodiment, the distance adjustment assembly 3 further includes a driving device, which is connected to the reel 31 and used to drive the reel 31 to rotate so as to wind or unwind the towing rope 32; the driving device can be a motor, and it is simpler and more convenient to drive the reel 31 to rotate.

When it is necessary to adjust the slope of the steel box girder wing plate 12 in the width direction, the telescopic end of the jack extends and abuts against the connection assembly 5, and then the telescopic end of the jack continues to extend to drive the steel box girder wing plate 12 to tilt to a predetermined slope angle by pushing the connection assembly 5, thereby completing the precise adjustment of the tilt angle of the steel box girder wing plate 12 so that the steel box girder wing plate 12 is accurately located at the predetermined assembly position, with a simple structure, convenient and fast operation, accurate positioning, high speed, high construction efficiency, and labor saving; among them, the telescopic device can also be a cylinder.

The top plate 52 is arranged parallel to the steel box girder wing plate 12. One end of the top plate 52 is vertically fixed with a support plate, and the end of the support plate away from the top plate 52 is installed on the steel box girder wing plate 12 through a second bolt structure. The bottom surface of the top plate 52 can abut against the telescopic end of the telescopic device.

Specifically, during hoisting, when the steel box girder wing plate 12 is hoisted to one side of the steel box girder main body 11 to be assembled by a crane, the staff detachably installs the distance adjustment assembly 3 and the angle adjustment assembly 4 on one side of the steel box girder main body 11 close to the steel box girder wing plate 12 to be assembled through the mounting seat 6, and makes the hook 33 correspond to the lifting ring 51, and the telescopic end of the jack corresponds to the top plate 52. When fine-tuning the distance between the steel box girder main body 11 and the steel box girder wing plate 12 according to the construction requirements, the motor drives the reel 31 to rotate, releases the towing rope 32, so that the hook 33 is buckled with the lifting ring 51, and then the motor drives the reel 31 to rotate, winds up the towing rope 32, thereby pulling the steel box girder wing plate 12 to move towards the steel box girder main body 11, so that the steel box girder wing plate 12 is accurately located at the predetermined assembly position. When adjusting the slope of the steel box girder wing plate 12 according to the construction requirements, after the telescopic end of the jack extends out and abuts against the top plate 52, the telescopic end of the jack continues to extend, thereby driving the steel box girder wing plate 12 to tilt to the predetermined slope angle in its width direction through the top plate 52 and the support plate, so that the steel box girder wing plate 12 is accurately located at the predetermined tilt angle. When the distance and angle adjustment are completed, the staff uses the welding plate 9 to temporarily fix the steel box girder wing plate 12 and the steel box girder main body 11, and carry out the assembly work of the steel box girder wing plate 12 on the other side.

When the telescopic end of the jack extends out to push the top plate 52 and the support plate to drive the steel box girder wing plate 12 to tilt to the predetermined slope angle, the limiting protrusion 521 is used to limit the telescopic end of the telescopic device to prevent it from slipping and separating from the top plate 52 during the tilting process of the steel box girder wing plate 12, thereby affecting the positioning effect. At the same time, it can prevent accidents from occurring to ensure the safety of the construction environment and increase the stability of the steel box girder wing plate 12.

[0056] As a preferred implementation manner, the number of the telescopic devices is two or more, and the telescopic devices are evenly distributed along the length direction of the steel box girder main body 11. The number of the top plates 52 is two or more, and each top plate 52 corresponds to each telescopic device respectively; as Figures 2 - 6As shown, multiple telescopic devices and multiple top plates 52 corresponding to the telescopic devices increase the stability of angle adjustment, with fast, efficient, and good stability in positioning. Moreover, under the action of the uniform distribution of each telescopic device along the length direction of the steel box girder main body 11, when there is a slope requirement for the steel box girder wing plate 12 in its length direction, the slope can be adjusted in the length direction of the steel box girder wing plate 12 by making the extended lengths of each telescopic device inconsistent, so as to complete the adjustment of the required slope.
