Description

Technical Field

[0001] This application relates to the field of hoisting equipment technology, and in particular to a T-shaped hoisting tool for installing and removing the movable sealing ring of the inlet ball valve of a pumped storage power station. Background Technology

[0002] The inlet ball valve of a pumped storage power station is an important component of current power engineering construction. The inlet ball valve is a ball valve used to control and cut off the inlet and outlet flow. It is mainly used between the water intake system and the pump turbine of the pumped storage power station. It is an important protective valve in the power plant building, and its performance directly affects the operational safety of the power station.

[0003] The movable sealing ring of the inlet ball valve is an embedded part installed inside the valve body and is a vulnerable component with a precision-machined surface. During installation and disassembly, if the lifting force point is not properly applied, it is easy to fall off. In addition, it is difficult to move it to a fixed position in the axial direction. The process and assembly precision requirements are high, which is a difficult point in the installation and disassembly work. Utility Model Content

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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] To address the aforementioned problems, this application provides a T-shaped lifting tool for installing and removing the movable sealing ring of the inlet ball valve in a pumped storage power station. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 The T-shaped lifting tool shown is used for installing and removing the movable sealing ring of the inlet ball valve of a pumped storage power station. It includes: a lifting lug 1, a horizontal plate 2, a vertical plate 3, a first reinforcing plate 4, a second reinforcing plate 5, and a through hole 6. The lifting lug, the square steel plate, and the reinforcing plate are cut, assembled, and welded from 20mm thick steel plates to form a T-shaped lifting tool. Specifically, the horizontal plate 2 and the vertical plate 3 are square plates. The vertical plate 3 is vertically fixed below the horizontal plate 2 to form a T-shape. The lifting lug 1 is fixed on one side above the horizontal plate 2. The first reinforcing plate 4 and the second reinforcing plate 5 are located between the horizontal plate 2 and the vertical plate 3, respectively on both sides of the vertical plate 3. A through hole 6 is formed at the bottom end of the vertical plate 3. This constitutes a T-shaped lifting tool. In use, the through hole 6 is fixedly connected to the bolt hole of the movable sealing ring by bolts. The lifting equipment hooks onto the lifting lug 1 at the top to lift the sealing ring. During lifting, the sealing ring is located on one side of the vertical plate 3, which serves both as a positioning function and as a means of easy observation, reducing the risk of equipment collision. Moreover, the structure of this application is simple, facilitating the lifting of the sealing ring without taking up space, and is well-suited for actual on-site installation, thus improving work efficiency.

[0026] In one embodiment, for ease of hoisting, the vertical plate 3 is positioned at two-thirds of one side of the horizontal plate 2; the first reinforcing plate 4 is positioned below the horizontal plate 2 on the side closer to the lifting lug 1, with one side connecting to the vertical plate 3 occupying one-quarter of the length of the vertical plate 3; the second reinforcing plate 5 is positioned below the horizontal plate 2 on the side farther from the lifting lug 1, with one side connecting to the vertical plate 3 occupying four-fifths of the length of the vertical plate 3; three through holes 6 are arranged side by side, and the diameter of the opening should be slightly larger than the diameter of the bolt hole of the movable sealing ring to facilitate subsequent bolt connection and tightening. The lifting lug 1 is a single-hole lifting lug, with an arched shackle at its top for easy hoisting during installation and disassembly. During welding, after smoothing, the components are welded sequentially according to the diagram, with the weld joint type being a T-shaped joint and the weld type being a fillet weld. After the T-shaped lifting fixture is fully welded, the weld non-destructive testing should be performed on the weld after the weld is completed and passes the visual inspection; only after passing the inspection can it be put into use.

[0027] 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.

[0028] 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.

[0029] 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. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
