Abstract
Description
Technical Field
[0001] This application relates to the field of water conservancy and hydropower engineering technology, specifically to a crane beam track leveling structure. Background Technology
[0002] In the construction of crane beam tracks in water conservancy and hydropower projects, track leveling is directly related to the stability of crane operation and structural safety. Traditional methods achieve leveling by wedging leveling steel shims between the track and the embedded steel plate, but this technique has significant drawbacks. First, manually placing the steel shims relies on construction experience, making it difficult to precisely control the track elevation, easily leading to localized unevenness. This can cause increased vibration during crane operation, accelerate track wear, and even threaten equipment safety. Second, the steel shims lack a reliable connection to the main structure. Under long-term dynamic loads and environmental corrosion (such as the high humidity environment of water conservancy projects), the steel shims are prone to loosening, displacement, or corrosion, requiring frequent maintenance and adjustments, increasing operation and maintenance costs. Furthermore, in traditional solutions, the shims are only fixed to the track and embedded plate by friction, resulting in poor overall load-bearing capacity and a tendency to create stress concentration, affecting the structural bearing capacity, especially under heavy crane loads, potentially causing localized deformation or even damage.

[0023] like Figure 1-2 As shown in the figure, this application embodiment provides a crane beam track leveling structure, which mainly includes a first steel plate 1, a leveling steel plate 4, and secondary concrete 6. The first steel plate 1 is fixedly installed on the top of the track beam 2, and at least two bolts 3 are directly or indirectly installed on one side of the top of the first steel plate 1. The leveling steel plate 4 is arranged opposite to the first steel plate 1, and there is a preset gap between the leveling steel plate 4 and the first steel plate 1. Two track pressure plates 5 are installed on the leveling steel plate 4, and the two track pressure plates 5 are located on both sides of the track 15 and are pressed against the track 15. The bolts 3 penetrate the leveling steel plate 4 and the track pressure plates 5. The first steel plate 1, the leveling steel plate 4, and the track pressure plates 5 are connected by connectors installed on the bolts 3. The connectors can adjust the gap between the leveling steel plate 4 and the first steel plate 1. The secondary concrete 6 is poured between the leveling steel plate 4 and the first steel plate 1 after the leveling steel plate 4 is adjusted to the preset position.
[0024] In this embodiment, the crane beam track leveling structure fixes the first steel plate 1 to the top of the track beam 2. The first steel plate 1, leveling steel plate 4, and track pressure plate 5 are connected by connectors and bolts 3. Adjusting nuts 12 adjust the positions of the leveling steel plate 4 and track pressure plate 5, ensuring that the surface elevation of the track 15 meets the accuracy requirements. After leveling the leveling steel plate 4, secondary concrete 6 is poured between the leveling steel plate 4 and the first steel plate 1 to fix them together. This crane beam track leveling structure can improve leveling accuracy while ensuring the stability of the leveling structure during use.
[0025] like Figure 1 As shown, in one specific embodiment, the first steel plate 1 is pre-embedded in the top of the track beam 2, and multiple anchoring bars 7 are welded to the bottom of the first steel plate 1. The multiple anchoring bars 7 are arranged at intervals and extend into the track beam 2. The anchoring bars 7 are welded to the track beam reinforcing bars 8 of the track beam 2 to form an integral load-bearing structure, thereby improving the stability of the entire crane beam track leveling structure when the track 15 is running.
[0026] like Figure 1 As shown, in one specific embodiment, the connector includes a nut 12, an elastic washer 13, and a flat washer 14 fitted onto the bolt 3. Alternatively, the connector can be other components capable of adjusting the relative height of the leveling steel plate 4. For example, the bolt 3 can be replaced with a threaded rod, and the connector can be a double-nut 12 structure, where one nut 12 is installed on the bottom side of the leveling steel plate 4, and the other is installed on the top side of the track pressure plate 5. By rotating and adjusting the positions of the two nuts 12, the positions of the leveling steel plate 4 and the track pressure plate 5 relative to the first steel plate 1 can be adjusted and leveled. Other similar structures can also be used, which will not be elaborated upon here. Furthermore, the top of the secondary concrete 6 is flush with the top of the leveling steel plate 4. Specifically, after the elevation of the track 15 is adjusted and positioned, secondary concrete 6 is poured on the surface of the track beam 2, and the surface of the secondary concrete 6 is flush with the top surface of the leveling steel plate 4, thereby better ensuring the load-bearing and deformation requirements of the track 15 under crane load conditions.
[0027] like Figure 2 As shown, in one specific embodiment, a crane beam stop 9 is provided at the end of the track 15. The crane beam stop 9 is fixedly installed on the top of the stop embedded plate 10. The stop embedded plate 10 is fixedly connected to the track beam 2 at the corresponding position through a plurality of embedded plate reinforcing bars 11 arranged at intervals. The position of the crane can be limited by the crane beam stop 9.
[0028] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
