Description

Technical Field

[0001] This utility model relates to the field of tensioning device technology, and in particular to a tensioning wheel device specifically used on a winding disc. Background Technology

[0002] Spiral tube heat exchangers have unparalleled advantages over ordinary shell and tube heat exchangers. They are applicable to a wide temperature range, adaptable to thermal shock, self-relief of thermal stress, and have high compactness. Due to their special structure, the flow field is fully developed and there are no dead zones. In particular, by setting up multiple tubes (single shell), multiple fluids can be exchanged simultaneously in one device.

[0003] Spiral coil heat exchangers are highly efficient and compact heat exchangers that not only utilize waste heat but also play a vital role in energy conservation and environmental protection. However, their complex structure, high cost, and location within a critical part of the equipment make them problematic.

[0004] A spiral heat exchanger is made by alternately winding heat transfer tubes in a spiral shape in the space between the core and the outer cylinder. The spiral directions of adjacent spiral heat transfer tubes are opposite, and a spacer of a certain shape is used to maintain a certain distance between them.

[0005] Spiral coiled tubes can be wound as a single strand or as two or more strands welded together and then wound together. A medium can pass through the tube, which is called a single-channel spiral coiled tube heat exchanger.

[0006] One of the most important processes in the manufacturing of wound tube heat exchangers is the tube winding process, typically involving round (hollow) tubes. These round tubes are first wound onto a custom-made tube coil, from which the winding process continues. Current custom-made tube coils use a common disc structure, relying on rotation and external tension or traction to pull the tubes out. However, due to the special structure of the round (hollow) tube and the manufacturing requirements of wound tube heat exchangers, the tubes need to be straightened and given a certain tension during operation to ensure reliable output. Current common discs cannot meet these requirements, and relying on manual tension checks poses significant safety hazards in practical applications. Utility Model Content

[0007] In response to the shortcomings of the existing production technology, the applicant provides a tensioning wheel device specifically designed for use on a pipe winding disc, which can greatly improve the reliability of round pipe conveying, maintain tension during the pipe feeding process, meet usage requirements, and ensure pipe winding quality.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A tensioning wheel device specifically designed for use on a tube coil includes two sets of custom tube coils symmetrically distributed front and rear for placing hollow circular tubes. The two sets of custom tube coils are distributed vertically in the height direction, and each set of custom tube coils is arranged symmetrically at the same height on the left and right sides.

[0010] The structure of a single customized tube coil includes: spaced right-angle fixing plates and fixing seats, and an inner cylinder fixing plate fixed to the inner ring of the customized tube coil. A brake disc is mounted on the outer end face of the inner cylinder fixing plate via a rotating shaft. A pneumatic brake is mounted on the bottom of the brake disc. The rotating shaft is supported by a set of spaced bearing seats. A swing seat is fixed to the bottom of the bearing seats. An adjusting rod is installed between the middle position of the upper part of the swing seat and the right-angle fixing plates. A tension detection sensor is installed on the adjusting rod. The outer end face of the swing seat is hinged to the fixing seat.

[0011] The outer ring of the custom tube coil is fixed with spaced wool felt sheets, and hollow round tubes are wrapped around the outside of the wool felt sheets.

[0012] As a further improvement to the above technical solution:

[0013] It also includes vertically arranged support and positioning columns, with rectangular beams symmetrically distributed on the support and positioning columns, and customized tube coils installed at the left and right ends of each rectangular beam.

[0014] The central axis of a single rectangular beam is perpendicular to the central axis of the supporting positioning column.

[0015] The right-angle fixing plate and the fixing seat are respectively locked to the side of the rectangular beam by fasteners.

[0016] The customized tubing has an I-shaped cross-section.

[0017] The customized tube coil includes an inner cylinder assembly, with a first side plate and a second side plate symmetrically fixed at both ends of the inner cylinder assembly; the inner cylinder assembly includes a thin-walled inner cylinder, with three support frames evenly spaced on the outer circumference of the thin-walled inner cylinder, and wool felt sheets fixed on the outer surface of each support frame; a fixing block fixed to the inner cylinder fixing plate is provided inside the inner cylinder assembly, and multiple positioning plates are also arranged at one end of the inner cylinder assembly, with the positioning plates connected to the first side plate.

[0018] Both the first and second side plates are thin-plate structures. The first side plate is fitted onto one end of the inner cylinder assembly and locked in place with fasteners. The second side plate is welded to the other end of the inner cylinder assembly.

[0019] The thin-walled inner cylinder has three circular holes evenly spaced in the circumferential direction, and small oblong holes are symmetrically opened on both sides of each circular hole. A support frame is inserted into the small oblong holes. Three rectangular thin-plate inner positioning plates are evenly spaced on the inner wall of the thin-walled inner cylinder, and the inner positioning plates are locked to the support frame.

[0020] The support frame is an arc-shaped thin plate, and the support frame is attached to the outer surface of the thin-walled inner cylinder.

[0021] The support frame has a π-shaped cross-section. Symmetrical connecting plates extend downward from the bottom of the support frame. Each connecting plate has a large elongated hole. The connecting plates fit into the inner positioning plate and are locked in place using fasteners.

[0022] The beneficial effects of this utility model are as follows:

[0023] This utility model has a compact and reasonable structure and is easy to operate. Through the unique design of the customized tube disc, the cooperation between components such as the tension detection sensor, pneumatic brake and brake disc can easily complete the reliable output of the whole disc of round tubes, and can provide timely feedback of tension to ensure the tension of the round tubes, which greatly improves the working stability and ensures the quality of the tube winding.

[0059] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0060] like Figures 1-10 As shown, the tensioning wheel device for custom tube discs in this embodiment includes two sets of custom tube discs 100 symmetrically distributed front and back for placing hollow round tubes. The two sets of custom tube discs 100 are distributed vertically in the height direction, and each set of custom tube discs 100 is arranged symmetrically at the same height on the left and right sides.

[0061] The structure of a single customized tube coil 100 includes spaced right-angle fixing plates 201 and fixing seats 202, and an inner cylinder fixing plate 1200 fixed to the inner ring of the customized tube coil 100. A brake disc 1100 is mounted on the outer end face of the inner cylinder fixing plate 1200 via a rotating shaft 500. A pneumatic brake 1300 is mounted on the bottom of the brake disc 1100. The rotating shaft 500 is supported by a set of spaced bearing seats 600. A swing seat 1000 is fixed to the bottom of the bearing seats 600. An adjusting rod 400 is installed between the upper middle position of the swing seat 1000 and the right-angle fixing plates 201. A tension detection sensor 401 is installed on the adjusting rod 400. The outer end face of the swing seat 1000 is hinged to the fixing seat 202.

[0062] The outer ring of the custom tube coil 100 is fixed with spaced wool felt sheets 901. The wool felt sheets 901 are wrapped around the hollow round tube. The design of the wool felt sheets 901 can protect the hollow round tube.

[0063] It also includes vertically arranged support positioning columns 300, on which rectangular beams 200 are symmetrically distributed front and back, and customized tube coils 100 are installed at the left and right ends of each rectangular beam 200.

[0064] The central axis of the single rectangular beam 200 is perpendicular to the central axis of the supporting positioning column 300.

[0065] The right-angle fixing plate 201 and the fixing seat 202 are respectively locked to the side of the rectangular beam 200 by fasteners.

[0066] The cross-section of the custom tube coil 100 is I-shaped.

[0067] The customized tube coil 100 includes an inner cylinder assembly 900, with a first side plate 700 and a second side plate 800 symmetrically fixed at both ends of the inner cylinder assembly 900; the inner cylinder assembly 900 includes a thin-walled inner cylinder 903, with three support frames 902 evenly spaced on the outer circumference of the thin-walled inner cylinder 903, and wool felt sheets 901 fixed on the outer surface of each support frame 902; a fixing block 904 fixed to the inner cylinder fixing plate 1200 is provided inside the inner cylinder assembly 900, and a plurality of positioning pieces 905 are arranged at one end of the inner cylinder assembly 900, the positioning pieces 905 being connected to the first side plate 700.

[0068] Both the first side plate 700 and the second side plate 800 are thin-plate structures. The first side plate 700 is fitted onto one end of the inner cylinder assembly 900 and locked in place with fasteners. The second side plate 800 is welded to the other end of the inner cylinder assembly 900.

[0069] The thin-walled inner cylinder 903 has three circular holes 908 evenly spaced in the circumferential direction. Small elongated holes 907 are symmetrically opened on both sides of each circular hole 908. A support frame 902 is inserted into the small elongated holes 907. Three rectangular thin-plate inner positioning plates 906 are evenly spaced on the inner wall of the thin-walled inner cylinder 903. The inner positioning plates 906 are locked to the support frame 902.

[0070] The support frame 902 is a thin arc plate, and the support frame 902 is attached to the outer surface of the thin-walled inner cylinder 903.

[0071] The support frame 902 has a π-shaped cross-section. Symmetrical connecting plates 909 extend downward from the bottom of the support frame 902. Each connecting plate 909 has a large elongated hole 910. The connecting plate 909 fits against the inner positioning plate 906 and is locked with fasteners.

[0072] In actual engineering processes, the work is completed through the following steps:

[0073] First, a whole roll of hollow round tube is wound around the custom tube coil 100;

[0074] Secondly, the head of the hollow tube is output from the customized tube disk 100 and finally wound around the workpiece mandrel (not shown in the figure). During the process of the hollow tube being wound around the mandrel, it will generate a reverse pull on the customized tube disk 100. The tension detection sensor 401 detects the magnitude of the tension (usually the tension detection range is 0-2000N).

[0075] Then, the tension detected by the tension sensor 401 in the second step and the working pressure of the pneumatic brake 1300 (working pressure range is 0-0.7MPa) are set as follows: Figure 10 The inverse proportional function relationship shown:

[0076] If the tension sensor 401 detects a tension of 1500N, the electronic control system will control the pneumatic brake 1300 to operate at a pressure of 0.1MPa.

[0077] If the tension sensor 401 detects a tension of less than or equal to 500N, the electronic control system will control the pneumatic brake 1300 to operate at a maximum pressure of 0.7MPa.

[0078] If the tension sensor 401 detects a tension exceeding 1500N, the electronic control system will control the pneumatic brake 1300 to fully release.

[0079] Finally, this ensures that the round tube is always under tension when it is output from the customized tube coil 100, and also avoids the risk of the customized tube coil 100 tipping over due to excessive reverse tension generated by the round tube during the process of winding the round tube around the workpiece mandrel, thus ensuring a safety factor.

[0080] By following the steps above, it is possible to conveniently output the round tube while simultaneously providing real-time feedback on the working pressure and controlling the operation of the pneumatic brake 1300, ensuring smooth output of the round tube and maintaining it in a taut state throughout the output process to meet usage requirements.

[0081] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
