It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0031] like Figures 1 to 5 As shown, on the one hand, the embodiments of this application provide a duct structure 1, which includes a duct seat 10 and a cover 20, which can improve the convenience of assembling and maintaining the fan 2 and better meet the needs of production and after-sales use.

[0032] The duct base 10 is used to support and install the fan 2, which includes fan blades 201. The type of fan 2 can be determined according to actual needs, and may be, for example, a cross-flow fan, a centrifugal fan, etc., which is not limited in this embodiment. Correspondingly, the type of fan blades 201 can be determined according to the type of fan 2, and may be, for example, a cross-flow fan blade, a centrifugal fan blade, etc., which is not limited in this embodiment. In some embodiments, the fan 2 may be a cross-flow fan, and the fan blades 201 of the fan 2 may be cross-flow fan blades.

[0033] The cover 20 is disposed on the air duct seat 10 and includes a volute tongue 21 and a second sidewall 22 spaced apart. The air duct seat 10, the volute tongue 21, and the second sidewall 22 enclose an air duct cavity for accommodating the fan blades 201 of the fan 2. In some embodiments, the cover 20 may be an air outlet assembly disposed at the air outlet of the hoist 100, which also serves as an air outlet guide. The volute tongue 21 may include a first sidewall and a third sidewall connected at an incline. The first sidewall and the second sidewall 22 are spaced apart to enclose an air outlet cavity located in the air outlet assembly, and the air outlet cavity is connected to the air duct cavity.

[0034] When assembling the fan 2, the fan 2 can be first installed on the duct seat 10, and then the cover 20 can be installed on the duct seat 10 so that the duct seat 10, the volute tongue 21, and the second side wall 22 enclose and form a duct cavity, allowing the fan blade 201 to be safely and reliably located within the duct cavity. When maintaining the fan 2, the cover 20 can be removed from the duct seat 10 to expose the fan 2, facilitating cleaning, inspection, and other maintenance operations.

[0035] Compared with related technologies, the air duct structure 1 provided in this application embodiment is divided into an air duct seat 10 and a cover 20, which can facilitate the assembly and maintenance of the fan 2 without the need to disassemble the air duct structure 1 as a whole. This effectively improves the convenience of assembling and maintaining the fan 2 and better meets the needs of production and after-sales use.

[0036] In some embodiments, the duct seat 10 may be provided with a bearing step 11, which is used to support the cover 20. By providing the bearing step 11, the positioning and docking area between the duct seat 10 and the cover 20 can be increased, thereby improving the assembly accuracy and connection stability of the duct seat 10 and the cover 20.

[0037] Here, the supporting step portion 11 may be provided with a first insertion hole 111, and the cover member 20 may be provided with a first insertion flange 23. The first insertion flange 23 is inserted into the first insertion hole 111 to connect and fix the air duct seat 10 and the cover member 20. By setting the insertion structure, quick installation and disassembly between the supporting step portion 11 and the cover member 20 can be achieved. The number of first insertion holes 111 and first insertion flanges 23 can be determined according to actual needs, and may be one or more, which is not limited in this embodiment. For example, the supporting step portion 11 may be provided with multiple first insertion holes 111, and the cover member 20 may be provided with multiple first insertion flanges 23. The multiple first insertion holes 111 and multiple first insertion flanges 23 are inserted one-to-one, and a reliable connection between the supporting step portion 11 and the cover member 20 is achieved through multiple insertion structures.

[0038] In some embodiments, the air duct base 10 may have a motor mounting portion and a bearing mounting portion at opposite ends along a first direction, where the first direction is the extension direction of the rotating shaft of the fan 2. A fan blade mounting portion 14 is formed between the motor mounting portion and the bearing mounting portion, and the sidewall, volute tongue 21, and second sidewall 22 of the fan blade mounting portion 14 enclose a duct cavity. The fan 2 may include a fan blade 201, a drive motor 202, and a support bearing (not shown). The drive motor 202 is used to drive the fan blade 201 to rotate, and the support bearing is used to support the end of the fan blade 201. The motor mounting portion is used to mount the drive motor 202, the fan blade mounting portion 14 is used to accommodate and mount the fan blade 201, and the bearing mounting portion is used to mount the support bearing.

[0039] In some embodiments, the air duct structure 1 is adapted for use in a ceiling-mounted crane 100. For example... Figures 1 to 6 and Figure 8 As shown, the ductwork 100 may include a chassis 3. The chassis 3 has a first fastening part 301 and a second fastening part 302 spaced apart. The ductwork seat 10 has a third fastening part 15 and a fourth fastening part 16 on opposite sides along a second direction. The first fastening part 301 and the third fastening part 15 are engaged, and the second fastening part 302 and the fourth fastening part 16 are engaged, so that the ductwork seat 10 is mounted on the chassis 3. The first and second directions are perpendicular or inclined. One of the first fastening part 301 and the third fastening part 15 is a male fastening part, and the other is a female fastening part. Similarly, one of the second fastening part 302 and the fourth fastening part 16 is a male fastening part, and the other is a female fastening part. By setting the above-mentioned fastening structure, the ductwork seat 10 can be easily fastened and fixed to the chassis 3, achieving a quick positioning connection between the ductwork seat 10 and the chassis 3, simplifying the installation steps.

[0040] In some examples, the chassis 3 may have a through hole 306, and the duct seat 10 may have a threaded hole 17. A fastening screw passes through the through hole 306 and is fixedly connected to the threaded hole 17 to secure the duct seat 10 and the chassis 3. Thus, after the duct seat 10 is fastened to the chassis 3, the threaded connection structure further secures the duct seat 10 and the chassis 3, increasing the reliability of the connection between them.

[0041] like Figures 1 to 8 As shown, in some examples, the hoist 100 may include a decorative cover 4. The duct seat 10 may have a fifth fastening part 18, and the decorative cover 4 may have a sixth fastening part 401, which are fastened together. Here, one of the fifth fastening part 18 and the sixth fastening part 401 is a male fastening part, and the other is a female fastening part. By fastening the decorative cover 4 and the duct seat 10 together, the surface of the decorative cover 4 does not need to have connecting holes, ensuring the surface of the decorative cover 4 is intact and aesthetically pleasing. For example, the decorative cover 4 may be located at the end of the hoist 100, in which case the decorative cover 4 is an end decorative cover.

[0042] For example, the chassis 3 may include a base plate 303 and a side plate 304, with the side plate 304 formed on the edge of the base plate 303. The side plate 304 has a clearance portion 305, and a fifth fastener 18 passes through the clearance portion 305 and engages with a sixth fastener 401, so that the decorative cover 4, the side plate 304, and the air duct seat 10 are sequentially abutted and fixed. Here, the clearance portion 305 may be a clearance hole or a clearance groove.

[0043] For example, the fifth fastening portion 18 may include two spaced-apart elastic arms 181, and the sixth fastening portion 401 is a fastening arm. The two elastic arms 181 elastically deform to clamp the sixth fastening portion 401, so that the fifth fastening portion 18 and the sixth fastening portion 401 are reliably fastened together.

[0044] like Figures 1 to 8 As shown, on the other hand, this application embodiment provides a pedestal crane 100, which includes an air duct structure 1 and a fan 2 as described in any of the above embodiments, with the fan 2 disposed on the air duct structure 1. The pedestal crane 100 provided in this application embodiment has the aforementioned air duct structure 1, which can improve the convenience of assembling and maintaining the fan 2, and better meet the needs of production and after-sales use.

[0045] The duct structure and the mounting machine provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
