Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, and in particular to a device for cleaning the bottom protective layer of a circular tunnel. Background Technology

[0002] Cleaning the protective layer at the bottom of tunnels is a crucial engineering task, especially in the construction and maintenance of water conservancy projects, traffic tunnels, and underground engineering projects. The main purpose of cleaning the protective layer at the bottom of tunnels is to ensure that the internal space of the tunnel meets design requirements, while removing waste generated during construction or operation to maintain the normal function and safety of the tunnel. In existing technologies, the cleaning of circular tunnels mainly relies on manual labor or traditional machinery, which suffers from low cleaning efficiency, high labor intensity, and numerous safety hazards. Cleaning work is particularly difficult in damp and muddy tunnel environments. Therefore, a more efficient and convenient tool for cleaning the tunnel bottom is needed. Utility Model Content

It has a simple structure, is easy to operate, and has high cleaning efficiency. It can reduce the workload of manual cleaning, reduce the intensity of manual labor, and significantly improve the cleaning efficiency of circular tunnels.

[0004] This application provides a device for cleaning the bottom protective layer of a circular tunnel, including an excavator bucket 1, a steel protective shaping plate 2, a fixed steel plate 3, a rubber working plate 4, and fixing bolts 5; the fixed steel plate 3 is installed on the back of the excavator bucket 1, the steel protective shaping plate 2 is installed on the fixed steel plate 3, the steel protective shaping plate 2 is perpendicular to the shovel teeth of the excavator bucket 1, and the bottom end of the steel protective shaping plate 2 is located on the lower side of the back of the excavator bucket 1 where the shovel teeth are located. The lower end of the steel protective shaping plate 2 has an installation hole, and the rubber working plate 4 is installed on both sides of the lower end of the steel protective shaping plate 2 through the installation hole by fixing bolts 5.

[0005] Optionally, in some embodiments, the bottom end of the rubber working plate 4 is 2 cm longer than the bottom end of the steel protective shaping plate 2.

[0006] Optionally, in some embodiments, the bottom ends of the steel protective shaping plate 2 and the rubber working plate 4 are both arc-shaped structures that match the curvature of the tunnel bottom.

[0007] Optionally, in some embodiments, a limiting wheel 6 is provided on the back of the excavator bucket 1 where the shovel teeth are located.

[0009] This application features a simple structure, convenient operation, and high cleaning efficiency. Made from materials such as steel plates, rubber, and bolts, it is installed on the back of the excavator bucket, enabling seamless integration of excavation and cleaning functions.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] To address the aforementioned issues, this application provides an apparatus for cleaning the bottom protective layer of a circular tunnel, which can reduce the workload of manual cleaning, lower the intensity of manual labor, and significantly improve the cleaning efficiency of circular tunnels.

[0021] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0022] See Figure 1 The device for cleaning the bottom protective layer of the circular tunnel includes an excavator bucket 1, a steel protective shaping plate 2, a fixed steel plate 3, a rubber working plate 4, and fixing bolts 5. The fixed steel plate 3 is installed on the back of the excavator bucket 1, and the steel protective shaping plate 2 is installed on the fixed steel plate 3. The steel protective shaping plate 2 is perpendicular to the shovel teeth of the excavator bucket 1, and the bottom end of the steel protective shaping plate 2 is located on the lower side of the back of the excavator bucket 1 where the shovel teeth are located. The lower end of the steel protective shaping plate 2 has an installation hole, and the rubber working plate 4 is installed on both sides of the lower end of the steel protective shaping plate 2 through the installation hole by fixing bolts 5.

[0023] During operation, the excavator bucket 1 is installed on the wheeled excavator, and the digging and loading function is used to clean the thicker surface stone debris. Then, the bucket angle is adjusted appropriately, and the bottom sediment is scraped off using the rubber working plate 4 on the back of the bucket. The digging and loading and cleaning functions are integrated. By repeating this step and with appropriate manual labor, the bottom protective layer of the tunnel can be cleaned quickly. The steel protective shaping plate 2, rubber working plate 4, fixing bolts 5 and other materials are used to form the structure and are installed on the back of the excavator bucket 1. This can achieve seamless connection between the digging and loading and cleaning functions, reduce the amount of manual cleaning, reduce the labor intensity, and greatly improve the cleaning efficiency of circular tunnels. The rubber working plate 4 clamps the steel protective shaping plate 2 on both sides to prevent the scraper from damaging the already lined concrete during the bottom cleaning process.

[0024] In some implementations, see Figure 2 The bottom end of the rubber working plate 4 is 2cm longer than the bottom end of the steel protective shaping plate 2; the bottom ends of both the steel protective shaping plate 2 and the rubber working plate 4 are arc-shaped structures that match the curvature of the tunnel bottom.

[0025] During operation, the ends of the steel protective shaping plate 2 and the rubber working plate 3 are cut into arc shapes, which can effectively remove the bottom deposits. The bottom end of the rubber working plate 4 is 2cm longer than the bottom end of the steel protective shaping plate 2, which can prevent the steel protective shaping plate 2 from damaging the lined concrete during the cleaning process.

[0026] In some embodiments, a limiting wheel 6 is provided on the back of the excavator bucket 1 where the shovel teeth are located. The diameter of the limiting wheel 6 is smaller than the length of the steel protective shaping plate 2 that extends beyond the back of the excavator bucket 1 where the shovel teeth are located.

[0027] During operation, the setting of the limit wheel 6 can limit the downward pressure of the steel protective shaping plate 2, and to a certain extent avoid the steel protective shaping plate 2 from damaging the lined concrete.

[0028] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
