[0033] To enable those skilled in the art to which this application pertains to more clearly understand this application, the following will, in conjunction with the accompanying drawings in the embodiments of this application, clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of this application.

[0034] In life, it is often necessary to fix the combination of some pipes with special shapes, such as heating and superheating devices, etc. With the increase in the boiler capacity and parameters, in order to improve the boiler efficiency and steam temperature regulation, a large number of horizontal serpentine tube bank convection heating surfaces are usually arranged in the tail shaft of the boiler. In order to prevent the horizontal serpentine tube bank from deforming or moving in position, specific fixing devices need to be set for such pipes with special shapes.

[0035] The utility model patent with the patent publication number CN218380569 discloses a serpentine tube row installation device, belonging to the technical field of tube row heat exchange. The serpentine tube row installation device includes a support plate. Multiple parallel holes are opened on the main body side of the support plate, and semi-circular holes corresponding to the parallel holes one by one are opened inside the main body of the support plate. The semi-circular holes are communicated with the parallel holes. A circular sleeve a and a circular sleeve b are sequentially fixed at the bottom end of the support plate. A vertically arranged sleeve column passes through the inner cavities of the circular sleeve a and the circular sleeve b. The bottom end of the sleeve column is fixed on a positioning block, and the positioning block is fixed on the upper surface of the ventilation beam. Flat steel a in the shape of a long strip is arranged on both sides of the positioning block. The serpentine tube row in the serpentine tube row installation device is movably assembled with the installation part, which is convenient for the separate removal of the serpentine tube row, can ensure the reuse of the equipment, save resources and reduce costs.

[0036] However, when the serpentine tube row installation device is actually used and the serpentine tube generates undulating oscillations, the serpentine tube is easily separated from the serpentine tube row installation device, resulting in poor fixing stability of the serpentine tube by the serpentine tube row installation device.

[0037] To solve the technical problem of poor fixing stability of the serpentine tube by the serpentine tube installation device in the related art, this application provides a serpentine tube fixing device. Please refer to Figures 1 to 2 , the serpentine tube fixing device includes a support assembly 20 and a pressing and fixing assembly 30.

[0038] The support assembly 20 includes a support plate 21 and a support bar 22 located on one side of the support plate 21 and connected to the support plate 21. The support bar 22 is welded to one side of the support plate 21. It should be noted that the connection method between the support bar 22 and the support plate 21 can also be screwed or clamped, etc., which can be set according to the actual situation, and this application does not make a limitation.

[0039] The support plate 21 and the support bar 22 extend along a preset direction respectively. A plurality of spaced support grooves 23 are formed on one side of the support bar 22 away from the support plate 21. The plurality of support grooves 23 are evenly formed on one side of the support bar 22 away from the support plate 21. The support grooves 23 penetrate through the support bar 22 perpendicular to the preset direction. The serpentine pipe 10 is arranged in parallel on one side of the support bar 22 away from the support plate 21, and a plurality of rows of pipes of the serpentine pipe 10 are sequentially installed in the plurality of support grooves 23, realizing the connection and cooperation between the plurality of pipes of the serpentine pipe 10 and the plurality of support grooves 23.

[0040] The pressing and fixing assembly 30 is located on one side of the support bar 22. The pressing and fixing assembly 30 includes a pressing plate 31 extending along the preset direction. The pressing plate 31 is detachably connected to the support bar 22, and the pressing plate 31 covers the support groove 23.

[0041] Since the plurality of support grooves 23 are spaced along the preset direction on the support bar 22, and the pressing plate 31 covers the support groove 23, then the plurality of rows of pipes of the serpentine pipe can be sequentially placed in the plurality of support grooves 23, and the pressing plate 31 can limit the installation of the plurality of pipes in the support grooves 23, so as to prevent the plurality of pipes from detaching from the support grooves 23 and improve the stability of the serpentine pipe fixing device for fixing the serpentine pipe.

[0042] Please refer to Figure 1 、 Figure 2 and Figure 5 , the serpentine pipe 10 is installed on one side of the support assembly 20. Two stud bolts 27 are symmetrically welded on one side of the support assembly 20. The pressing and fixing assembly 30 is connected to the two stud bolts 27 together. Stud nuts 28 are installed on the two stud bolts 27, and the two stud nuts 28 are both pressed against the pressing and fixing assembly 30, so that the pressing and fixing assembly 30 is stably installed on one side of the support assembly 20 through the stud bolts 27 and the stud nuts 28. Two through holes 34 are formed on the pressing plate 31. The two through holes 34 are symmetrically formed on the pressing plate 31 and are connected and cooperated with the corresponding stud bolts 27. Fixing assemblies 40 are installed at both the upper and lower ends of the support assembly 20, which is convenient for the installation and fixation of the serpentine pipe fixing device, ensures the stability of the serpentine pipe fixing device, prevents the deformation and movement of the serpentine pipe, and improves the stability of the serpentine pipe fixing device for supporting and fixing the serpentine pipe.

[0043] According to the installation position height required by the serpentine pipe, by adjusting the distance between the fixing component 40 and the supporting component 20, the support bar 22 in the supporting component 20 is connected and matched with the serpentine pipe; then, the fixing component 40 is connected to the equipment, so as to realize the stable fixation of the position of the supporting component 20. Then, the pressing and fixing component 30 is installed on the supporting component 20 to block and press one side of the serpentine pipe 10 installed on the supporting component 20, thus completing the installation and fixation of the serpentine pipe. The operation is convenient and the installation is simple. By pressing and fixing the serpentine pipe 10 installed on the supporting component 20 through the pressing and fixing component 30, the serpentine pipe 10 can be prevented from detaching from the serpentine pipe fixing device, and the reliability and stability of the serpentine pipe fixing device for installing and fixing the serpentine pipe can be improved.

[0044] Through the cooperation setting of the supporting component 20 and the pressing and fixing component 30, by connecting the pressing and fixing component 30 to the equipment, the height of the supporting component 20 can be adjusted, so that the supporting component 20 can be matched with the height of the serpentine pipe, so as to facilitate the supporting component 20 to support the serpentine pipe.

[0045] Through the settings of the supporting component 20, the pressing and fixing component 30, the stud 27 and the bolt cap 28, compared with the prior art, the pressing and fixing component 30 is installed on the supporting component 20 through the cooperation of the stud 27 and the bolt cap 28. When the pressing and fixing component 30 is installed on the supporting component 20, one side of the serpentine pipe can be extruded, so that under the block of the bolt cap 28, the installation position of the serpentine pipe can be fixed, avoiding the relative shaking between the serpentine pipe and the device, and thus avoiding the serpentine pipe from falling off the device, thereby improving the firmness of the installation of the serpentine pipe.

[0046] Please refer to Figures 1 to 5 , the pressing plate 31 is provided with at least two through holes 34 arranged at intervals. The supporting component 20 includes a stud 27 and a bolt cap 28, and at least two studs 27 and bolt caps 28 can be respectively provided. The two studs 27 are installed at intervals on one side of the supporting plate 21 close to the support bar 22, and the through hole 34 is sleeved in the stud 27. At least two bolt caps 28 are respectively sleeved on one side of the stud 27 far from the supporting plate 21 and are in contact with the pressing plate 31. In this way, the pressing plate 31 can be stably installed on one side of the support bar 22 through the stud 27 and the bolt cap 28, and a plurality of pipes are stably limited in the trough 23, preventing the plurality of pipes from detaching from the trough 23 and improving the stability of the serpentine pipe fixing device for fixing the serpentine pipe.

[0047] When there are two studs 27, the two studs 27 are respectively close to the two end parts of the supporting plate 21 along the preset direction, and the support bar 22 is located between the two studs 27. The spaced arrangement of the two studs 27 can improve the connection strength and connection stability between the pressing plate 31 and the supporting plate 21 through the stud 27 and the bolt cap 28.

[0048] In some embodiments, the support assembly 20 includes at least two first magnetic members (not shown in the figure). The two first magnetic members are spaced apart and installed on the support plate 21 and are respectively close to the two ends of the support plate 21 along the vertical direction. The pressing and fixing assembly 30 includes at least two second magnetic members (not shown in the figure). The two second magnetic members are spaced apart and installed on the pressing plate 31. The second magnetic member is magnetically attracted to the first magnetic member. By using the magnetic attraction between the first magnetic member and the second magnetic member, the pressing plate 31 can be stably installed on the support plate 21. In this way, while making a firm connection between the pressing plate 31 and the support plate 21, the structure can be simplified and the manufacturing cost of the serpentine tube fixing device can be reduced.

[0049] Please refer to Figures 3 to 4 , a card slot 24 is formed between two adjacent support slots 23 on the support bar 22. The pressing plate 31 is provided with a limiting slot along a preset direction. A plurality of spaced limiting blocks 35 are connected in the limiting slot along the preset direction (which can be understood as the vertical direction). The limiting blocks 35 are respectively clamped in the corresponding card slots 24. A through slot 32 is formed by clamping between the plurality of limiting blocks 35. The plurality of limiting blocks 35 are in the limiting slot, so that a plurality of through slots 32 can be formed in the limiting slot along the preset direction. The plurality of through slots 32 are uniformly arranged on the pressing plate 31. A plurality of card slots 24 are provided and are respectively formed between two adjacent support slots 23 on the support bar 22 along the vertical direction.

[0050] During specific implementation, the plurality of support slots 23 cooperate with the plurality of pipes arranged in rows of the serpentine tube, so that the plurality of pipes of the serpentine tube 10 can be horizontally placed in the plurality of support slots 23. The plurality of support slots 23 provide support for the plurality of pipes of the serpentine tube 10. The pressing plate 31 is pressed against one side of the support bar 22, and the pressing plate 31 covers the support slot 23 to prevent the plurality of pipes from detaching from the support slot 23, thereby improving the stability of the serpentine tube fixing device for fixing the serpentine tube.

[0051] A plurality of spaced arc slots 33 are formed on the pressing plate 31. The two sides of the through slot 32 along the direction perpendicular to the preset direction are respectively connected to the arc slots 33. The arc slots 33 penetrate through the pressing plate 31 along the direction perpendicular to the preset direction. The arc slots 33 correspond to the support slots 23. The notch of the arc slot 33 is semi-circular, and the notch of the support slot 23 is semi-circular. The arc slot 33 and the support slot 23 enclose a fixing channel with a circular cross-section. The diameter of the circular cross-section is equal to or slightly larger than the cross-section of the plurality of pipes of the serpentine tube 10, so that the plurality of pipes of the serpentine tube 10 can be firmly limited in the fixing channel, thereby improving the stability of the installation and fixing of the plurality of pipes of the serpentine tube 10.

[0052] During specific implementation, by respectively inserting the plurality of limiting blocks 35 into the corresponding card slots 24, the outside of the support slot 23 is inserted into the through slot 32, and the arc slots 33 on both sides cooperate to press and fix the serpentine tube, so as to realize the pressing and fixing of the plurality of pipes of the serpentine tube installed in the support slot 23 by the pressing plate 31. The structure is simple and the assembly is convenient, which can improve the convenience and stability of the installation and fixing of the serpentine tube.

[0053] Please refer to Figures 1 to 5 Figures 1 to 5

[0054] The two connecting plates 25 are respectively perpendicularly welded to both ends of the support plate 21, and the two fixing components 40 are respectively connected to the corresponding connecting plates 25. Bolting holes are formed in the connecting plates 25, and the bottom ends of the fixing components 40 are inserted and matched with the bolting holes.

[0055] The serpentine tube fixing device further includes a fixing component 40. The fixing component 40 is connected to the connecting plate 25. The fixing component 40 includes at least two bolt rods 41, a fixing plate 42 and a nut 43. The bolt rods 41 are movably inserted into the corresponding bolting holes and respectively extend into the clamping space 26. The fixing plate 42 is welded to one end of the bolt rod 41.

[0056] The nut 43 is screwed onto the bolt rod 41 and abuts against the connecting plate 25. At least two nuts 43 are provided. The two nuts 43 are respectively located on both sides of the connecting plate 25 (one nut 43 is arranged at the bottom of the connecting plate 25, and the other nut 43 is arranged at the top of the connecting plate 25) and respectively abut against the connecting plate 25.

[0057] During specific implementation, by loosening the two nuts 43, the bolt rods 41 can be adjusted in height, so that the installation height of the support component 20 can be fixed under the cooperation of the two fixing components 40, which is convenient for the support component 20 to cooperate with the serpentine tube.

[0058] The working principle of the present application is as follows: Move the serpentine tube fixing device to clamp the equipment that can be used to fix the serpentine tube fixing device in the clamping space 26. Twist the bolt rods 41 so that the two bolt rods 41 respectively tightly abut against the equipment, and twist the two nuts 43 located on both sides of the connecting plate 25 so that the two nuts 43 respectively tightly abut against the upper and lower sides of the connecting plate 25, so as to stably limit the length of the bolt rods 41 extending into the clamping space 26 and stably install the serpentine tube fixing device on the equipment.

[0059] The multiple pipes of the coiled pipe 10 are respectively clamped in a plurality of vertically arranged brackets 23. The plurality of brackets 23 are arranged in the vertical direction. When the multiple pipes of the coiled pipe 10 are in the same plane, they can be sequentially installed in the plurality of brackets 23 to prevent the deformation and position movement of the coiled pipe 10. Then, the pressing plate 31 is covered on the plurality of brackets 23, and the plurality of limiting blocks 35 are respectively inserted into the corresponding card slots 24, so that the outside of the bracket 23 is inserted into the through slot 32, and the arc slots 33 on both sides cooperate to press and fix the coiled pipe, realizing the pressing and fixing of the multiple pipes of the coiled pipe installed in the bracket 23 by the pressing plate 31. Finally, the stud 27 is screwed to the stud 27 and on the side of the pressing plate 31 away from the support plate 21, so that the pressing plate 31 is firmly covered on the bracket 23, ensuring that the multiple pipes of the coiled pipe 10 are firmly limited in the bracket 23. Thus, under the blocking of the bolt cap 28, the installation position of the coiled pipe can be fixed, avoiding relative shaking between the coiled pipe and the device, and thus preventing the coiled pipe from falling off the device, thereby improving the firmness of the installation of the coiled pipe.

[0060] The coiled pipe fixing device can realize the installation and clamping fixation of the coiled pipe. The clamping fixation is reliable, not easy to fall off, and can be appropriately adjusted according to the height of the coiled pipe installed in the equipment, thereby improving the practicability and convenience of the coiled pipe fixing device for installing and fixing the coiled pipe.
