Description

Technical Field

[0001] This utility model relates to the field of industrial fan installation technology, and in particular to a steel pipe fixing structure for industrial fans. Background Technology

[0002] In industrial fans, steel pipes serve as crucial load-bearing and connecting components, typically penetrating and fixed to the rear center of the fan body. Both ends are rigidly connected to the upper building structure and the lower fan body, respectively. The core function of this steel pipe is to form a robust suspension frame, effectively transferring the immense weight of the fan body and the complex loads generated during operation to the fixed support point at the top of the building. Therefore, the reliability and stability of its fixation directly affect the safe and stable operation of the entire fan system, making it an indispensable and crucial component in the structural design of industrial fans.

[0003] The steel pipe fixing structure of existing industrial fans generally adopts welding or simple bolt locking. Welding will cause the steel pipe to be permanently fixed to the supporting structure, which not only causes stress concentration and has the potential for cracking, but also makes subsequent disassembly and maintenance extremely difficult. The traditional bolt locking structure is mostly single-point or asymmetrical fixing, which is prone to loosening under the continuous vibration generated by the long-term operation of the fan. In addition, due to the lack of an effective centering adjustment mechanism, it is easy to cause skew during installation, resulting in uneven stress on the steel pipe, posing a risk of working at height, and affecting the efficiency of equipment maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a steel pipe fixing structure for industrial fans, which solves the problem that the steel pipe fixing structure of industrial fans in the prior art generally adopts welding or simple bolt locking methods, which not only causes stress concentration and cracking risks, but also makes subsequent disassembly and maintenance extremely difficult.

[0005] To achieve the above objectives, a steel pipe fixing structure for an industrial fan is provided, including a fan body, a plurality of suspension cables on the outer peripheral mounting part at the rear end of the fan body, a connecting frame installed at the middle of the rear end of the fan body, a connecting piece fixedly installed at the other end of the connecting frame by bolts, and a fixing ring fixedly installed at one end of the inner side of the connecting piece by bolts.

[0006] The fixed ring 1 is rotatably connected to the inside of the rotating ring 1, and the outer extension end of the rotating ring 1 is rotatably connected to the threaded block 2, and the threaded block 2 is threaded with a bidirectional screw.

[0007] According to the steel pipe fixing structure for an industrial fan, two sliding grooves are opened opposite each other on the rotating ring, and a sliding shaft is slidably connected inside the two sliding grooves.

[0008] According to the aforementioned steel pipe fixing structure for an industrial fan, a clamping block is fixedly connected to the inner end of the sliding shaft, and the inner ends of the two clamping blocks are respectively provided with steel pipe bodies.

[0009] According to the aforementioned steel pipe fixing structure for an industrial fan, a fixing ring two is fixedly installed on the inner side of the other end of the connector by bolts, and a rotating ring two is rotatably connected inside the fixing ring two.

[0010] According to the aforementioned steel pipe fixing structure for an industrial fan, the outer extension end of the rotating ring two is rotatably connected to a threaded block one, which is also threaded with a bidirectional screw.

[0011] According to the steel pipe fixing structure for an industrial fan, two sliding grooves are opened opposite each other on the inner side of the rotating ring two, and a sliding shaft two is slidably connected inside the sliding groove two.

[0012] According to the aforementioned steel pipe fixing structure for an industrial fan, a U-shaped clamp is fixedly connected to the inner end of the sliding shaft two. The clamp and the U-shaped clamp are both located at the inner ends of the rotating ring one and the rotating ring two, and both ends of the clamp are in contact with the inner end faces of the rotating ring one and the rotating ring two.

[0013] The above solution has beneficial effects:

[0014] 1. This device adopts a two-way screw synchronous drive for two sets of rotating ring mechanisms. Through the ingenious cooperation of the sliding groove and the sliding shaft, the four sets of clamping points achieve synchronous radial contraction. This two-way centering clamping mechanism not only makes the steel pipe uniformly stressed and avoids local deformation, but also greatly enhances the vibration resistance and clamping stability through the composite clamping method of surface contact and line contact. It is especially suitable for the working conditions of continuous operation of industrial fans.

[0015] 2. This device can simultaneously control the opening and closing of all clamping points by rotating a single bidirectional screw in both directions. This design transforms the traditional multi-point fixing that required individual disassembly into centralized control, reducing the disassembly and assembly time of steel pipes by several times and greatly facilitating daily inspection and maintenance. At the same time, the modular connector design makes partial replacement easier, effectively reducing maintenance and time costs.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model provides a steel pipe fixing structure for an industrial fan, including a fan body 2. Several suspension cables 1 are installed on the outer rear end of the fan body 2. A connecting frame 3 is installed in the middle of the rear end of the fan body 2. A connector 4 is fixedly installed at the other end of the connecting frame 3 with bolts. A fixing ring 6 is also fixedly installed at one end of the inner side of the connector 4 with bolts. The suspension cables can be fixedly installed on the ceiling to ensure the stable operation of the fan body 2 and prevent it from falling.

[0026] The fixed ring 6 is rotatably connected to a rotating ring 10. The outer extension end of the rotating ring 10 is rotatably connected to a threaded block 14. A double-ended screw 5 is threaded onto the threaded block 14. Two sliding grooves 7 are opened opposite each other on the rotating ring 10. A sliding shaft 9 is slidably connected inside the two sliding grooves 7. A clamping block 11 is fixedly connected to the inner end of the sliding shaft 9. A steel pipe body 12 is correspondingly set at the inner end of the two clamping blocks 11. By setting the sliding grooves 7, they can cooperate with the sliding shaft 9. During the rotation of the rotating ring 10, the sliding shaft 9 will drive the sliding shaft 9 to change position, so that the sliding shaft 9 drives the clamping block 11 to move inward gradually, thus clamping the steel pipe. The clamping component can be released by rotating the double-ended screw 5 in the opposite direction, thus improving the applicability of the device.

[0027] The inner end of connector 4 is bolted to a fixing ring 15. A rotating ring 16 is rotatably connected inside the fixing ring 15. A threaded block 8 is rotatably connected to the outer extension end of the rotating ring 16. The threaded block 8 is also threadedly engaged with the double-ended screw 5. Two sliding grooves 18 are oppositely formed on the inner side of the rotating ring 16. A sliding shaft 17 is slidably connected inside the sliding grooves 18. A U-shaped clamp 13 is fixedly connected to the inner end of the sliding shaft 17. The clamp 11 and the U-shaped clamp 13 are both located at the inner ends of the rotating ring 10 and the rotating ring 16, with both ends in contact with the inner end faces of the rotating ring 10 and the rotating ring 16. The external bolts ensure that... The bidirectional screw 5 rotates, and under the action of the threaded engagement, it can drive the two threaded blocks to move relative to each other. The threaded block 8 can drive the rotating ring 16 to rotate, and the threaded block 14 can drive the rotating ring 10 to rotate, so that the two rotating rings rotate relative to each other. Secondly, during the rotation of the two rotating rings, due to the restriction of the two sets of internal sliding grooves and sliding shafts, the clamping block 11 and the U-shaped clamping plate 13 gradually move inward. During the approach, the U-shaped clamping plate 13 can cooperate with the two ends of the steel pipe body 12 to complete the clamping and fixing. In addition, during the inward movement of the clamping block 11, it can also clamp and fix the other two ends of the steel pipe, which greatly improves the fixing effect of the steel pipe.

[0028] Working principle: In use, the fan body 2 can be installed on the ceiling via the suspension cable 1. When the steel pipe body 12 needs to be installed, the steel pipe body 12 is first passed through the internal cavity of the connector 4. Then, the double-ended screw 5 is rotated by the external bolts. Under the action of the threaded engagement, it can drive the two threaded blocks to move relative to each other. The threaded block 1 8 can drive the rotating ring 2 16 to rotate, and the threaded block 2 14 can drive the rotating ring 10 to rotate, so that the two rotating rings rotate relative to each other. Secondly, during the rotation of the two rotating rings, due to the restriction of the two sets of internal sliding grooves and sliding shafts, the clamping block 11 and the U-shaped clamping plate 13 gradually move inward. During the approach, the U-shaped clamping plate 13 can cooperate with the two ends of the steel pipe body 12 to complete the clamping and fixing. During the inward movement of the clamping block 11, it can also clamp and fix the other two ends of the steel pipe, which greatly improves the fixing effect of the steel pipe. While the fixing effect is good, it also makes it easy for the staff to disassemble and maintain it later, improving the convenience and practicality of the device.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
