During the final acceptance process, the four-corner height difference inspection of the supports of the completed box girder is required. Currently, this is done manually using a handheld internal ruler. Because the supports for the completed box girder erection are located at the top of the piers, the measurement and inspection workspace is often very narrow. Furthermore, the work is performed at height, making the measurement inconvenient, labor-intensive, inefficient, and posing significant safety risks. This is especially true when pier hanging rails are not installed. Furthermore, the work requires multiple trips back and forth to the piers, requiring a high level of manpower.

[0012] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0013] See also Figures 1 and 2 A device for measuring the height difference of the four corners of a high-speed railway simply supported beam support includes a laser level 10 arranged at the outer corner of a pad stone 11 and a vertical ruler assembly arranged on the lower base plate 8 of the support.

[0014] The vertical ruler assembly includes a ruler 1, which is vertically fixed in the center of a base 5. At least three dispersed permanent magnet blocks 6 are fixed under the base 5. A support rod 2 extending laterally along the back of the ruler 1 is fixedly connected. The support rod 2 is connected to the upper end of a handheld rod 4 using an L-shaped connector 3. The handheld rod 4 adopts a telescopic structure, and the support rod 2 is rotatably connected to the L-shaped connector 3.

[0015] In this embodiment, the position of the rotational connection between the support rod 2 and the L-shaped connector 3 is defined by two nuts 9. The two nuts 9 are respectively connected to the support rod 2 and are located on either side of one corner of the L-shaped connector 3. The other corner of the L-shaped connector 3 is connected to the top of the handheld rod 4. Loosening the nuts 9 adjusts the left and right position of the ruler. The rotational connection between the support rod 2 and the L-shaped connector 3 allows the base 5 of the ruler to fit against the support surface, thereby placing the ruler in a measuring state. The base 5 is made of hard plastic, is lightweight, and is easy to use. The permanent magnet blocks 6 are evenly arranged along the circumference of the base 5.

[0016] Application and working principle of this utility model:

[0017] When the high-speed railway box girder needs to measure and inspect the height difference of the four corners of the support, first, place a laser level 10 at a corner outside the pad 12. The laser level 10 will draw a horizontal line 11, which can hit the scale located at the three corners of the support lower base plate 8. Then, the scale 1 is successively placed at the three corners of the support lower base plate 8, and readings ①②③ are taken. The fourth corner at the diagonal position of the laser level cannot be read, and the data is obtained by calculation. The calculation method is: add the two data on a diagonal line that have been read ①+③, subtract the data on the diagonal line that cannot be read ②, and the result is the data ④ at the diagonal position of the laser level that cannot be read, and ①+③)-②=④.

[0018] Use the hand-held rod 4 to place the ruler 1 on the corner of the lower base plate of the support. Since a permanent magnet block 6 is provided under the base 5 of the ruler, it can be fixed on the upper surface of the lower base plate 8 of the support to form a stable reading state, ensuring that the height difference of the four corners of the support is read accurately and with reliable precision during measurement.

[0019] The measurement space on the support's lower baseplate 8 is very narrow, so using a handheld rod 4 to set up the scale 1 facilitates easy operation and ensures safe construction. A laser level 10 can be manually placed outside the pad 12. Using the horizontal line 11 drawn by the laser level 10 to mark the reading, inspectors can complete the elevation difference measurement of the four corners of the support from the ground. This eliminates the need for overhead work, resulting in simple and quick operation, effectively reducing labor input, lowering operational risks, and improving measurement efficiency and safety. This is particularly significant when the pier column suspension fence is not installed, achieving a significant safety improvement.

[0020] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, which all fall within the scope of protection of the present invention.
