Description

Technical Field

[0001] This application relates to the field of support equipment technology, and in particular to a detachable wind turbine frame device for use outside tunnels. Background Technology

[0002] With the rapid advancement of national water conservancy infrastructure construction and the improvement of people's quality of life, in order to fully leverage the coordinated development of water conservancy infrastructure construction and the safety of workers, tunnels are constructed using a combination of drill-and-blast and TBM methods. This necessitates high requirements for air quality within the tunnels, requiring the installation of ventilation fans. These fans are mounted on frames. For long water conservancy tunnels, ventilation fan frames utilize either reinforced concrete strip foundations with steel platforms or concrete column foundations with steel platforms. While these technologies offer controllable ventilation effects, the reusability of the fan frames is limited. With the shift towards reusable fan frame installation methods, existing ventilation frames need to be dismantled to transport large equipment into the tunnel. Previously, this involved cutting the existing steel columns and demolishing the concrete, resulting in low efficiency, time-consuming, labor-intensive, and wasteful work. There is a need to research a detachable, reusable fan frame to improve the speed of dismantling and installing tunnel ventilation fan frames, ensuring the progress of tunnel construction.

While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0022] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. 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. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. 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.

[0025] To address the aforementioned issues, this application provides a detachable wind turbine frame device for use outside tunnels. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram illustrates a detachable ventilation fan frame device for tunnels, comprising: a base 1, a bottom column 2, a connecting plate 3, a vertical column 4, a crossbeam 5, and a vertical beam 9. The base 1 is constructed of cast concrete. The foundation and fan frame at the tunnel entrance are cast according to the tunnel cross-section and the size of the large equipment to be installed inside the tunnel. Simultaneously, the bottom column 2 is embedded within the base 1 as a pre-embedded component. The connecting plate 3 consists of two symmetrical square plates; one is fixed to the top of the bottom column 2, and the other is fixed to the bottom of the vertical column 4. The two connecting plates 3 are fastened together with screws for easy assembly and disassembly. The crossbeam 5 and vertical beam 9 are welded perpendicularly to each other to form multiple grid-shaped frames, which are detachably connected to the top of the vertical column 4.

[0027] In this device, the base 1 is first poured, and then the bottom column 2 is fixed inside the base 1 as an embedded part. When installing the overall support, the column 4 and the bottom column 2 are fastened with bolts, and then a grid-shaped frame is placed on top of the bottom column 2 to form the entire support frame. Finally, the fan 7 is fixed on the grid-shaped frame. Thus, this device uses bolted connections between the bottom column 2 and the column 4 for easy assembly and disassembly, and the top grid-shaped frame is also designed to be detachable for easy assembly and disassembly. Alternatively, another method to make the support more stable is to weld all components except the detachable connecting plate 3, and then use a hoisting device for overall lifting. This eliminates the need to break up the concrete or cut the steel columns of the fan frame for disassembly and hoisting.

[0028] In one embodiment, a detachable connection structure between a grid-shaped frame and a column 4 is provided with a connecting cover 91 at the contact point between the grid-shaped frame and the column 4, and the connecting cover 91 is fastened to the top of the column 4.

[0029] In one embodiment, a reinforcing connecting column 41 is provided between the column 4 and the beam 5 to improve support. The reinforcing connecting column 41 can be detachably fastened to the column 4 and the beam 5 respectively by bolts as needed. Of course, it can also be directly welded for fixed connection.

[0030] In one embodiment, a guardrail 6 is provided on the side of the grid-shaped frame near the column 4 to provide protection during the maintenance of the fan. Meanwhile, a ladder 10 is attached to one of the vertical beams 9 for easy access during maintenance.

[0031] In one embodiment, a side stop bar 8 for auxiliary support is provided on one side of the column 4 for auxiliary support and protection.

[0032] 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.

[0033] The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.

[0034] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
