Description

Technical Field

[0001] This utility model relates to the technical field of hoisting devices, and more specifically, to a tooling for disassembling and assembling a semi-molded rotating window. Background Technology

[0002] The semi-model rotating window mechanism on the middle section of the left side wall of the wind tunnel is a key component of the wind tunnel semi-model test system, and its performance directly affects the accuracy and stability of the test. This mechanism is generally installed on the side wall of the wind tunnel test section, and its core function is to stably support the semi-model, ensuring that it maintains the correct position and attitude in the complex and ever-changing airflow environment, providing a solid guarantee for the smooth conduct of the test. However, the disassembly and assembly of the semi-formed window rotating mechanism is quite cumbersome. The conventional procedure requires the entire wind tunnel sidewall to be disassembled before the semi-formed window rotating mechanism can be operated independently. Even more challenging is the sheer size and weight of the semi-formed window rotating mechanism, which necessitates the use of large lifting equipment such as gantry cranes for hoisting operations. Traditional hoisting methods have significant drawbacks. Before hoisting, connecting steel cables and other connectors to the semi-formed window rotating mechanism is a complex and time-consuming process; after hoisting, separation is required, further increasing the workload. More importantly, the direct connection between the steel cables and the semi-formed window rotating mechanism lacks stability, easily leading to loosening and slippage during hoisting. This not only affects hoisting efficiency but can also damage the mechanism and even cause safety accidents. Therefore, designing a more efficient and stable hoisting device is particularly urgent. Utility Model Content

Then, the connecting bolts between the mounting plate and the wind tunnel sidewall are removed. Next, multiple connecting plates are respectively clamped around the perimeter of the mounting plate, and hooks are hung on the lower side of the mounting plate. The first connecting hole on the connecting plate is aligned with the mounting hole on the mounting plate.

Detailed Implementation

[0015] Example The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 8As shown, the semi-molded rotating window assembly and disassembly fixture of this embodiment includes a wind tunnel sidewall 10 and a semi-molded rotating window disposed on the wind tunnel sidewall 10. The semi-molded rotating window includes a mounting plate 11 attached to the wind tunnel sidewall 10, mounting holes 13 opened on the mounting plate 11, and a rotating window mechanism 12 disposed in the middle of the mounting plate 11, including multiple connectors 20 disposed on the mounting plate 11, and a hoisting device 30 connected to the multiple connectors 20 simultaneously. The connector 20 includes a connecting plate 21 disposed on the mounting plate 11, an L-shaped hook 22 connected to the side of the connecting plate 21 near the rotating window mechanism 12, a first connecting hole 23 disposed on the connecting plate 21, and a first bolt 24 disposed through the first connecting hole 23. The upper end of the hook 22 is fixedly connected to the connecting plate 21, the lower end of the hook 22 abuts against the lower side of the mounting plate 11, and the first bolt 24 is threadedly connected to the mounting hole 13. Specifically, in use, first, the wind tunnel sidewall 10 is laid flat so that the semi-formed rotating window faces upward. Then, the connecting bolts between the mounting plate 11 and the wind tunnel sidewall 10 are removed. Then, multiple connecting plates 21 are respectively clamped around the perimeter of the mounting plate 11, and the hooks 22 are hung on the lower side of the mounting plate 11. The first connecting hole 23 on the connecting plate 21 is aligned with the mounting hole 13 on the mounting plate 11. Then, the first bolt 24 is passed through the first connecting hole 23 and the mounting hole 13 at the same time to connect the connecting plate 21 to the hoisting device 30. The semi-formed rotating window can then be hoisted. The U-shaped structure formed by the connecting plate 21 and the hook 22 is clamped on the side of the mounting plate 11. Then, the first bolt 24 limits the connection plate 21 and the mounting plate 11, which can achieve efficient and fast installation. During the hoisting process, there will be no shaking or loosening between the connecting plate 21 and the mounting plate 11, making the hoisting more efficient and stable.

[0016] In this embodiment, the connector 20 further includes a suspension plate 25 vertically disposed on the upper side of the connecting plate 21, and suspension holes 26 formed on the suspension plate 25; the hoisting device 30 is connected to the suspension plate 25. A pair of first connecting holes 23 are provided, with the pair of first connecting holes 23 respectively disposed on both sides of the suspension plate 25. The hoisting device 30 includes a hanging ring 31 suspended in the suspension hole 26, a hoisting rope 32 connected to the hanging ring 31, a connecting block 33 connected to multiple hoisting ropes 32, and a steel cable 34 connected to the connecting block 33; the steel cable 34 is used to connect to the crane. Specifically, a traditional gantry crane can be used as the crane, connected to the connecting block 33 via the steel cable 34, and then connected to the suspension plate 25 and the connecting plate 21 via the hoisting rope 32 and the hanging ring 31 to achieve the hoisting operation.

[0017] In this embodiment, multiple limiting components 40 are also included, with each limiting component 40 connected to a connector 20. Each limiting component 40 includes a limiting plate 41 positioned between the connecting plate 21 and the mounting plate 11, a limiting strip 42 located on the side of the limiting plate 41 away from the rotating window mechanism 12, and a second connecting hole 43 on the limiting plate 41. The limiting strip 42 is attached to the side of the mounting plate 11 away from the rotating window mechanism 12, and a first bolt 24 passes through the second connecting hole 43. The lower end of the limiting strip 42 near the mounting plate 11 is arc-shaped. Specifically, the limiting component 40 is mainly used when installing the semi-molded rotating window onto the wind tunnel sidewall 10. Its function is to restrict the position of the semi-molded rotating window using the limiting strip 42, improving installation accuracy and efficiency. Specifically, when slowly lowering the semi-molded rotating window, the limiting strip 42 can be used to restrict its position. It should be noted that the limiting plate 41 can be installed overlapping the connecting plate 21, or the limiting plate 41 can be installed separately. Multiple connecting plates 21 can be set only on opposite sides of the mounting plate 11, but limiting plates 41 and limiting strips 42 can be set around the mounting plate 11.

[0018] In this embodiment, the projections of the first connecting hole 23 and the second connecting hole 43 on the horizontal plane are both elongated. The length direction of the first connecting hole 23 is parallel to the length direction of the second connecting hole 43. Specifically, the elongated shape of the first connecting hole 23 and the second connecting hole 43 allows for greater tolerance when installing the connecting plate 21 and the limiting plate 41, reduces the precision requirements for the opening positions of the first connecting hole 23, the second connecting hole 43, and the mounting hole 13, and can also accommodate more models of mounting plates 11.

[0019] In this embodiment, the upper end of the limiting strip 42 is located above the limiting plate 41. A horizontally positioned second bolt 44 is provided at the upper end of the limiting strip 42. A threaded hole 27 is provided at one end of the connecting plate 21 near the limiting strip 42. The second bolt 44 is rotatably connected to the limiting strip 42 and threadedly connected to the threaded hole 27 on the connecting plate 21. Specifically, by tightening the second bolt 44, the connecting plate 21 and the limiting plate 41 can be fixed, allowing the limiting strip 42 and the hook 22 to clamp the mounting plate 11, preventing loosening.

[0020] In summary, the semi-molded rotating window assembly and disassembly fixture of this embodiment, when in use, first lay the wind tunnel sidewall 10 flat so that the semi-molded rotating window faces upward, then remove the connecting bolts between the mounting plate 11 and the wind tunnel sidewall 10, then clamp multiple connecting plates 21 around the perimeter of the mounting plate 11, and hang the hooks 22 on the lower side of the mounting plate 11. The first connecting hole 23 on the connecting plate 21 is aligned with the mounting hole 13 on the mounting plate 11. Then, the first bolt 24 passes through the first connecting hole 23 and the mounting hole 13 at the same time, connecting the connecting plate 21 to the hoisting device 30, so that the semi-molded rotating window can be hoisted. The U-shaped structure formed by the connecting plate 21 and the hook 22 is clamped on the side of the mounting plate 11, and the first bolt 24 limits the connection between the connecting plate 21 and the mounting plate 11, which can achieve efficient and fast installation. Moreover, during the hoisting process, there will be no shaking or loosening between the connecting plate 21 and the mounting plate 11, making the hoisting more efficient and stable.
