[0032] like Figures 1 to 4 As shown, a track adjustment mechanism comprises:

[0033] Two tracks 1 are arranged correspondingly and are arranged in an I-shape as a whole;

[0034] A plurality of bolts 2, the plurality of bolts 2 are evenly arranged on both sides of the track 1, and one end of the bolts 2 is fixed in the cement floor, the bolts 2 on both sides correspond to each other, and a support plate 21 is arranged on the corresponding two bolts 2, and the track 1 is arranged on the support plate 21;

[0035] Wherein, the distance between the corresponding bolts 2 is greater than the width of the track 1;

[0036] A U-shaped screw groove 21A is provided on the support plate 21, the opening of the U-shaped screw groove 21A faces outward, and its opening width and U-shaped curvature are matched with the bolt 2;

[0037] Gaskets 22 are provided on the upper and lower sides of the support plate 21 . Screw holes 22A are provided on the gaskets 22 . The bolts 2 pass through the screw holes 22A. The support plate 21 is clamped between the gaskets 22 on both sides.

[0038] The two tracks 1 are arranged correspondingly and present an I-shaped structure as a whole. A number of bolts 2 are evenly distributed on both sides of the track 1. One end of these bolts 2 is fixed in the cement floor. The bolts 2 on both sides correspond to each other. A support plate 21 is provided on each pair of bolts 2. The track 1 is placed on these support plates 21. The distance between the corresponding bolts 2 is greater than the width of the track 1. A U-shaped screw groove 21A is provided on the support plate 21. The opening of the U-shaped screw groove 21A faces outward. The opening width and U-shaped curvature of the U-shaped screw groove 21A match the bolt 2. Gaskets 22 are also provided on the upper and lower sides of the support plate 21. Screw holes 22A are provided on the gasket 22. The bolts 2 pass through these screw holes 22A to fix the support plate 21 between the gaskets 22 on both sides.

[0039] The bearing capacity and stability of the track 1 are improved by designing an I-shaped track 1 and evenly distributed bolts 2. The track 1 is placed on a support plate 21. The support plate 21 ensures that the track 1 is firmly fixed by the tight fit between the U-shaped screw groove 21A and the bolts 2, as well as the clamping between the gaskets 22. The matching design of the U-shaped screw groove 21A and the bolts 2 allows the track 1 to be adjusted in both the width and height directions, thereby increasing the versatility and flexibility of the track 1.

[0040] In this embodiment, a shock absorber 11 is arranged between the two rails 1. The shock absorber 11 includes a spring 11A and a damper 11B. The spring 11A is arranged below the rail 1 and one end of the spring 11A is in contact with the rail 1. The damper 11B is arranged inside the spring 11A.

[0041] The spring 11A is used to provide elastic support in the vertical direction, and the damper 11B is used to provide damping force to mitigate the vibration of the track 1 .

[0042] The spring 11A is installed under the track 1, and one end of the spring 11A is in direct contact with the track 1. The damper 11B is arranged on the inner side of the spring 11A. The spring 11A will show its inherent elastic characteristics when subjected to vertical loads, thereby effectively absorbing and dispersing the impact force caused by the transportation of the prefabricated box beam. The damper 11B further mitigates the vibration generated by the compression and release of the spring 11A by generating an appropriate amount of damping force, effectively preventing these vibrations from potentially damaging the track 1. By reducing the vibration during transportation, it not only protects the prefabricated box beam from damage, but also improves the transportation efficiency and safety.

[0043] In this embodiment, the track 1 is provided with anti-slip strips 12, which are evenly distributed along the length of the track 1 and fixed on the upper surface of the track 1;

[0044] The area of ​​the track 1 not covered by the anti-slip strip 12 is coated with an anti-slip coating;

[0045] The surface of the anti-skid strip 12 is provided with a granular structure, and the anti-skid coating is made of silica sand mixed coating.

[0046] The anti-slip strips 12 are evenly distributed along the length of the track 1 and fixed on the upper surface of the track 1. The surface is designed with a granular structure to increase the friction of the contact surface, effectively preventing the box girder from sliding during transportation. The areas of the track 1 not covered by the anti-slip strips 12 are coated with a mixed coating containing silica sand. The anti-slip coating also provides additional friction, enhances the anti-slip performance of the entire track 1, maintains the stability of the prefabricated box girder, and reduces the potential risk of accidents caused by sliding. The application of the anti-slip strips 12 and the anti-slip coating not only improves safety, but also extends the service life of the track 1 by reducing the wear related to sliding and friction that may occur during transportation.

[0047] In this embodiment, an elevation indicating device 3 is also provided. The elevation indicating device 3 includes a scale 31 and a pointer plate 32 . The scale 31 is fixedly arranged on the upper surface of the support plate 21 , and the pointer plate 32 is fixedly arranged on the top of the bolt 2 .

[0048] The scale 31 is fixedly set on the upper surface of the support plate 21, and the pointer plate 32 is fixedly set on the top of the bolt 2. The elevation of the current track 1 can be read intuitively, and the height of the track 1 can be monitored and adjusted in real time to ensure that the prefabricated box girder can be smoothly transported in scenarios with different height requirements. By using the scale 31 and the pointer plate 32, the height of the track 1 can be accurately measured and adjusted to adapt to various terrains and transportation conditions, ensuring the safety and stability of transportation. The presence of the elevation indicating device 3 also increases the flexibility of transportation operations, allowing rapid adaptation to changes in site conditions, such as efficient transportation adjustments at construction sites or between loading platforms at different heights.

[0049] In this embodiment, the surface of the scale 31 is coated with an anti-corrosion coating.

[0050] By applying the anti-corrosion coating, the durability of the scale 31 is significantly improved, thereby ensuring the long-term stable operation of the entire track 1. There is no need to frequently replace or maintain the elevation indicating device 3. Long-term protection not only reduces maintenance costs, but also improves the operating efficiency and reliability of the entire track 1. During transportation with long-term exposure to the external environment, anti-corrosion measures help maintain the consistency and accuracy of height measurements during transportation, ensuring the correct positioning and safe transportation of prefabricated box girders.

[0051] In this embodiment, a water guide groove is provided at the bottom of the track 1, and the water guide groove is used to drain the accumulated water.

[0052] By effectively draining accumulated water, the water trough helps keep the surface of Track 1 dry, thereby reducing corrosion and wear caused by moisture. Drainage measures ensure that Track 1 can maintain optimal performance in all weather conditions, especially in the rainy season or other environments where water accumulation may occur. A dry surface of Track 1 is essential for the safe transportation of prefabricated box girders. A slippery Track 1 may cause transportation safety problems. The presence of the water trough improves the durability and reliability of Track 1, ensures the safe use of Track 1 under adverse climatic conditions, reduces maintenance costs, and improves the operating efficiency of the entire Track 1.

[0053] In this embodiment, limit blocks 13 are fixedly provided at both ends of the track 1 , and the limit blocks 13 are used to limit the moving range of the track 1 .

[0054] Limit blocks 13 are fixedly provided at both ends of the track 1. Through the limit blocks 13, the movement of the track 1 is effectively controlled within a safe limit. The existence of the limit blocks 13 significantly improves the safety of the operation of the track 1, especially in the loading, unloading and transportation of prefabricated box girders, preventing the track 1 from accidentally shifting or derailing due to exceeding the predetermined movement range. The limit blocks 13 also help to maintain the precise alignment of the track 1 and keep the track 1 in a predetermined alignment state, which not only reduces the reduction in transportation efficiency caused by the deviation of the track 1, but also reduces potential safety risks. Since the track 1 will not exceed the set movement range, it can maintain its structural integrity and functionality under various operating conditions.

[0055] In this embodiment, a luminous coating is provided on the surface of the pointer plate 32, and the luminous coating is used to display elevation information in a low-light environment.

[0056] By applying a luminous coating, the pointer dial 32 becomes an important safety and efficiency tool, allowing operators to accurately read elevation data without additional lighting equipment. This not only improves work efficiency and reduces operational errors that may be caused by incorrect elevation readings, but also greatly enhances the safety of operations at night or in low light conditions.
