[0002] A steel box girder, also known as a steel plate box girder, is a common structural form for long-span bridges. It is generally used in bridges with larger spans. Because its appearance is like a box, it is called a steel box girder. Large steel structure bridges have gradually become the mainstream technology for highway construction. It generally consists of a top plate, a bottom plate, and a web, and has the advantages of good structural integrity, large torsional stiffness, and uniform transverse load distribution.

[0003] Currently, the installation of steel box girders is generally carried out on-site, and the steel main girder is gradually pushed into place through the jacking technology. The existing construction methods for the installation of high-altitude materials in the construction of steel box girders generally include: relying on large machinery for handling (there are safety hazards in the process of mechanical handling during cross-construction); using manual welding of clamping plates for positioning (the construction measure cost increases, the construction accuracy is not strict, and the efficiency is not high); erecting a full hall scaffold (the construction measure cost increases, and the installation and disassembly of the full hall scaffold).

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4, the present utility model provides a laser positioning and pushing system, including a steel box girder body 1. Symmetrically arranged at the bottom of the steel box girder body 1 are lower magnetic adsorption positioning ruler assemblies 2. Below the lower magnetic adsorption positioning ruler assemblies 2 is a lower laser locator 3. By symmetrically arranging the lower magnetic adsorption positioning ruler assemblies 2 at the bottom of the steel box girder body 1 and arranging the lower laser locator 3 below the lower magnetic adsorption positioning ruler assemblies 2, the laser emitted by the lower laser locator 3 reaches the position of the lower magnetic adsorption positioning ruler assemblies 2, and the offset can be measured by irradiating the laser with the lower laser locator 3. At the center of the bottom of the steel box girder body 1 is a bottom guiding and pushing mechanism 4. At one end of the steel box girder body 1 is an end pusher 5, which is fixedly installed through an anchor point. At the end of the steel box girder body 1 below the end pusher 5 is an end magnetic adsorption positioning ruler assembly 6. On one side of the steel box girder body 1 is a horizontal laser locator 7 that matches the end magnetic adsorption positioning ruler assembly 6. Using the bottom guiding and pushing mechanism 4 in cooperation with the end pusher 5 as the power source to implement power adjustment can greatly reduce the mechanical damage and inaccurate adjustment range that may be caused by personnel approaching. Through the cooperation of the end magnetic adsorption positioning ruler assembly 6 and the horizontal laser locator 7, the horizontal positioning of the steel box girder body 1 is achieved.

[0023] In one embodiment, please refer to the attached drawings of the specification Figure 2 As shown, traction rings 8 are symmetrically arranged on both sides and one end of the steel box girder body 1. An electric hoist 10 is connected to the traction rings 8 through traction ropes 9, and the bottom end of the electric hoist 10 is fixedly installed through a fixed mounting seat 11. By connecting the traction rings 8 with the traction ropes 9 and installing and positioning the electric hoist 10 through the fixed mounting seat 11, the lifting direction is stabilized by the traction force. Since the steel box girder is too large, local deviation of the lifting position is prevented.

[0024] In one embodiment, please refer to the attached drawings of the specification Figure 2 As shown, both the lower magnetic adsorption positioning ruler assembly 2 and the end magnetic adsorption positioning ruler assembly 6 include a ruler plate 12. Scale lines 13 are arranged on the ruler plate 12, and adsorption magnets 14 are symmetrically arranged on both sides of the ruler plate 12. The ruler plate 12 is adsorbed on the steel box girder body 1 through the adsorption magnets 14. The scale lines 13 arranged on the ruler plate 12 are used for positioning the steel box girder body 1.

[0025] In one embodiment, please refer to the attached drawings of the specification Figure 3As shown, the bottom guiding and pushing mechanism 4 includes a lower support frame 15. A pushing device body 16 is installed on the top of the lower support frame 15. The top of the pushing device body 16 is connected to an upper mounting cross plate 19 through a fixing block 17. Four groups of triangular connection blocks 18 are arranged between the fixing block 17 and the upper mounting cross plate 19. A guiding and supporting component 21 is detachably installed on the upper mounting cross plate 19 through mounting bolts 20. The pushing device body 16 drives the upper mounting cross plate 19 to rise, so that the guiding and supporting component 21 generates a jacking force. The installation bolts 20 facilitate disassembly and connection.

[0026] In one embodiment, please refer to the attached drawings of the specification Figure 4 As shown, the guiding and supporting component 21 includes a supporting fixed plate 22. A positioning block 23 is integrally arranged at the center of the supporting fixed plate 22. A rotating shaft 26 that penetrates through the positioning block 23 movably is arranged in the supporting fixed plate 22. A driving motor 25 connected to the rotating shaft 26 is installed on the outer wall of one end of the supporting fixed plate 22. Threaded areas 27 with opposite thread directions are arranged on both sides of the positioning block 23 on the rotating shaft 26. Sliding connection blocks 28 are connected to the threaded areas 27. Guiding sliding grooves 24 are symmetrically formed on the supporting fixed plate 22. The sliding connection blocks 28 penetrate through the guiding sliding grooves 24 and are connected to side positioning plates 29. Side guiding wheels 30 are movably connected to the side positioning plates 29 through a first movable shaft. Lower guiding wheels 31 are movably connected to the positioning block 23 through a second movable shaft. The driving motor 25 drives the rotating shaft 26 to rotate, so that the sliding connection blocks 28 on the threaded areas 27 are guided by the guiding sliding grooves 24, realizing the fitting of the side positioning plates 29 with both sides of the steel box girder body 1. The side guiding wheels 30 cooperate with the lower guiding wheels 31 to guide the translation of the steel box girder body 1.

[0027] In practical applications, lower magnetic adsorption positioning ruler assemblies 2 are symmetrically arranged at the bottom of the steel box girder body 1, and a lower laser locator 3 is arranged below the lower magnetic adsorption positioning ruler assemblies 2. The lower laser locator 3 emits laser light to reach the position of the lower magnetic adsorption positioning ruler assemblies 2. The offset can be measured by irradiating the laser light from the lower laser locator 3. Then, the bottom guiding and pushing mechanism 4 and the end pushing device 5 are used as power sources to implement power adjustment, greatly reducing the problems of mechanical injuries that may be caused by personnel approaching and inaccurate adjustment ranges. Through the cooperation of the end magnetic adsorption positioning ruler assembly 6 and the horizontal laser locator 7, the horizontal positioning of the steel box girder body 1 is realized. The utility model has a wide range of applications, does not require a large number of complex brackets to be built, and can be used for heavy, long and diverse materials that are commonly required to be transported in the air during steel structure construction. It can effectively and accurately position the steel box girder body 1 and is convenient for adjustment.
