Description

Technical Field

[0001] This application relates to the field of cable manufacturing branching, and in particular to a branching device for manufacturing nuclear power instrument cables using a cable cage winding machine. Background Technology

[0002] The cable cage winding device is usually fixed at the front end of the hollow shaft of the cable cage winding machine. The wire core and filler wire core enter the pressing die through the winding device in the required structural sequence of the cable, thereby forming the required cable core structure.

[0003] There are two specifications for the production of instrumentation cables inside nuclear power plant structures. One specification requires one filler core on each side of the intersection of the conductors, with another filler core in the middle of the four filler cores. This requires a structure with five filler cores in the center and four filler cores on the outside. The other specification requires one filler core on each side of the intersection of the conductors, with another filler core in the middle of the three filler cores. This requires four filler cores in the center and three filler cores on the outside. Existing cable cage stranding machine branching plates are completely inadequate for the production of instrumentation cables inside nuclear power plant structures, which involve more complex processes. Existing branching plates on cable cage stranding machines can only produce structures with four conductors or three conductors, with only one filler core in the center and four or three filler cores on the outside.

[0004] The existing wire divider structure requires the addition of a secondary wire divider to guide the filling core and ensure that the core enters the crimping die in the correct position. Adding a secondary wire divider requires more space, but the available space on site is limited. Utility Model Content

[0005] To reduce the floor space occupied by the branching device, this application provides a branching device for manufacturing nuclear power instrumentation cables using a cable cage winding machine.

[0006] The present application provides a branching device for manufacturing nuclear power instrumentation cables using a cable cage winding machine, which adopts the following technical solution:

[0007] A branching device for manufacturing nuclear power instrument cables using a cable cage stranding machine includes a core-filled branching component. One end of the core-filled branching component is fitted with a wire guide tube, and the core-filled branching component is located at the outlet end of the wire guide tube. A branching plate is also fitted onto the wire guide tube, and the branching plate is provided with a plurality of branching holes. The branching plate is mounted on a rotating stranding body to rotate synchronously with the rotating stranding body.

[0008] By adopting the above technical solution, the structural requirements for manufacturing instrumentation cables inside nuclear power plant shells can be met. The manufacturing of instrumentation cables inside nuclear power plant shells can be achieved with a compact structure, avoiding the use of secondary branching boards, saving space. Furthermore, the branching board rotates synchronously with the rotating strand, which facilitates the entry of the wire cores and filler cores into the filler branching component and subsequent processing flow in the required order. Existing ordinary branching boards are difficult to manufacture instrumentation cables with special structures required by customers. This solution enables the production of this structure by manufacturing a branching device, which reduces the required floor space compared to other modifications.

[0009] Preferably, the splitter plate includes a splitter mounting ring and a splitter main ring. The splitter mounting ring is fitted onto the cable guide tube. The inner wall of the splitter main ring is connected to the outer wall of the splitter mounting ring. The angle between the splitter mounting ring and the splitter main ring is less than 180°. The splitter main ring is disposed on the splitter mounting ring to form an extended conical surface. The splitter hole is formed on the splitter mounting ring and the splitter main ring.

[0010] Preferably, some of the branch holes are formed on the branch mounting ring, and the branch holes on the branch mounting ring are evenly distributed along the circumference of the branch mounting ring; the other part of the branch holes are formed on the branch main ring, and the branch holes on the branch main ring are evenly distributed along the circumference of the branch main ring; the number of branch holes on the branch main ring is greater than the number of branch holes on the branch mounting ring; each branch hole on the branch mounting ring can be at the same angle as one of the branch holes on the branch main ring.

[0011] By adopting the above technical solution, the branch plate consists of a branch mounting ring and a branch main ring, which are set at an angle of less than 180° to form an extended conical surface, making the distribution of branch holes more reasonable and facilitating the branching of wire cores and filler wire cores. The branch holes on the branch mounting ring and the branch main ring are evenly arranged circumferentially, and the number of branch holes on the branch main ring is greater than that on the branch mounting ring. At the same time, the branch holes on the mounting ring can be at the same angle as the branch holes on the main ring, which can effectively guide the filler cores and wire cores into the crimping mold in the correct position, meeting the process structure requirements of instrument cables inside the nuclear power plant shell.

[0012] Preferably, the end of the cable guide tube away from the core-filling branching component is provided with a thread, and a mounting plate is provided between the cable guide tube and the branching mounting ring. The mounting plate is threadedly connected to the cable guide tube, and the mounting plate and the branching mounting ring are detachably connected.

[0013] By adopting the above technical solution, a thread is provided at the end of the conduit away from the core-filling branching component, and a mounting plate with a threaded connection to the conduit is provided between the conduit and the branching mounting ring. The mounting plate and the branching mounting ring are detachably connected, which facilitates the installation and removal of the branching mounting ring and improves the convenience of device assembly and maintenance. At the same time, in conjunction with the setting of other components, it can meet the structural requirements for the production of instrumentation cables inside the nuclear power plant shell, and realize the manufacturing of instrumentation cables inside the nuclear power plant shell with a relatively compact structure.

[0014] Preferably, the connection point between the mounting plate and the branch mounting ring is located on the ring surface of the branch mounting ring.

[0015] By adopting the above technical solutions, the installation of the distribution plate and the conduit is more stable and reasonable, which facilitates the filling and wire cores to pass through the distribution hole in the correct position and enter the subsequent components. This meets the complex structural requirements of the instrument cables inside the nuclear power plant shell and improves the adaptability and convenience of the device. The overall cost of the device is low, which helps to reduce production costs.

[0016] Preferably, each of the branch holes is provided with a friction-reducing component, which is installed on the branch plate and can reduce the wear of the wire core passing through the branch hole.

[0017] By adopting the above technical solution, a conduit is installed at one end of the core-filling branching component and located at the outlet end. The conduit is fitted with a branching plate with branching holes and rotates synchronously with the rotating strand, which can separate the core-filling component and the wire core, meeting the branching requirements of nuclear power instrument cable manufacturing. Friction-reducing components are installed in the branching holes and mounted on the branching plate, which can reduce the wear of the wire core passing through the branching holes.

[0018] Preferably, the core-filling splitter includes a core-filling tube and an outer ring plate. One end of the core-filling tube is installed on the wire guide tube, and the core-filling tube is connected to the wire guide tube. The wire pressing die is installed inside the core-filling tube. The inner ring wall of the outer ring plate is installed on the outer ring wall of the core-filling tube, and the outer ring plate is located at the end of the core-filling tube away from the splitter plate. The outer ring plate has a plurality of arc grooves, which are evenly distributed along the circumference of the outer ring plate.

[0019] By adopting the above technical solution, the connection between the core filling tube and the guide tube allows the core filling tube to smoothly enter the core filling tube from the guide tube. The crimping die installed inside the core filling tube can extrude and shape the entering core filling tube. The outer ring plate is set at the end of the core filling tube away from the dividing plate and has several circumferentially evenly distributed arc grooves on it, which helps the core filling tube to enter the crimping die better according to a specific path and position, thereby helping to produce a nuclear power instrument cable structure that meets the requirements.

[0020] Preferably, the distance between the end of each of the arc grooves and the adjacent end of the adjacent arc groove is 10°.

[0021] By adopting the above technical solution, the layout requirements of instrument cable cores and filler cores in specific nuclear power plant shells can be met, so that the filler cores can be accurately entered into the crimping mold according to the required structure, which helps to produce cable core structures that meet the requirements. Moreover, the device has a simple structure, low cost, and can adapt to the production of cables of different specifications. The manufacturing of cables of different specifications can be achieved by simply changing the filler core distribution component.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The instrumentation cables inside the nuclear power plant are manufactured with a compact structure, avoiding the use of secondary branching boards, saving space. Furthermore, the branching board rotates synchronously with the rotating strand, which facilitates the entry of the wire cores and filler wire cores into the filler branching components and subsequent processing steps in the required order.

[0024] 2. A thread is provided at the end of the conduit away from the core-filling branching component, and a mounting plate with a threaded connection to the conduit is provided between the conduit and the branching mounting ring. The mounting plate and the branching mounting ring are detachably connected, which facilitates the installation and removal of the branching mounting ring and improves the convenience of device assembly and maintenance. At the same time, in conjunction with the setting of other components, it can meet the structural requirements for the production of instrumentation cables inside the nuclear power plant shell, and realize the manufacturing of instrumentation cables inside the nuclear power plant shell with a relatively compact structure.

[0025] 3. The connection between the core-filling tube and the guide tube allows the core-filling tube to smoothly enter the core-filling tube from the guide tube. The crimping die installed inside the core-filling tube can extrude and shape the entering core-filling tube and the core-filling tube. The outer ring plate is set at the end of the core-filling tube away from the dividing plate and has several circumferentially evenly distributed arc grooves on it, which helps the core-filling tube to enter the crimping die better according to a specific path and position, thereby helping to produce a nuclear power instrument cable structure that meets the requirements.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a branching device for manufacturing nuclear power instrumentation cables using a cable cage winding machine. (Refer to...) Figure 1 The cable distribution device for manufacturing nuclear power instrument cables using a cable cage winding machine includes a core-filled cable distribution component 1. One end of the core-filled cable distribution component 1 is fitted with a wire guide tube 2, and the core-filled cable distribution component 1 is located at the outlet end of the wire guide tube 2. A cable distribution plate 3 is also fitted on the wire guide tube 2, and the cable distribution plate 3 is provided with several cable distribution holes 4. The cable distribution plate 3 is installed on the rotating winding body so as to rotate synchronously with the rotating winding body.

[0032] The instrumentation cables inside the nuclear power plant are manufactured with a compact structure, avoiding the use of the secondary branch plate 3, saving space. Furthermore, the branch plate 3 rotates synchronously with the rotating strand, which facilitates the entry of the wire core and filler wire core into the filler branch piece 1 and subsequent processing steps in the required order.

[0033] Reference Figure 1 and Figure 2 The core-filled wire divider 1 includes a core-filled tube 11 and an outer ring plate 12. One end of the core-filled tube 11 is fixedly installed on the wire guide tube 2 by welding. The core-filled tube 11 is connected to the wire guide tube 2, and the wire pressing die is installed inside the core-filled tube 11. The inner ring wall of the outer ring plate 12 is integrally formed on the outer ring wall of the core-filled tube 11. The outer ring plate 12 is located at the end of the core-filled tube 11 away from the wire divider 3. The outer wall of the outer ring plate 12 is inclined in the direction away from the wire guide tube 2, forming an extended conical surface.

[0034] The outer ring plate 12 has several arc grooves 121 evenly distributed along its circumference. The distance between the end of each arc groove 121 and the nearest end of the adjacent arc groove 121 is 10°. Depending on the cable specifications, a core-filling branch member 1 with three or four arc grooves 121 can be selected. If the core-filling branch member 1 has three arc grooves 121, it is a three-part core-filling branch member 1; if the core-filling branch member 1 has four arc grooves 121, it is a four-part core-filling branch member 1.

[0035] Reference Figure 1 and Figure 3 The end of the conduit 2 away from the core-filling branching component 1 is threaded. A mounting plate 5 is installed at the threaded end of the conduit 2. The mounting plate 5 is threaded onto the conduit 2, and a locking nut 51 is screwed onto the threaded end of the conduit 2 near the core-filling tube 11 to abut against the mounting plate 5. The branching plate 3 is detached and installed on the mounting plate 5.

[0036] The splitter plate 3 includes a splitter mounting ring 31 and a splitter main ring 32. The splitter mounting ring 31 is fitted onto the cable conduit 2. The splitter mounting ring 31 is located on the side of the mounting plate 5 away from the core-filling splitter component 1. The splitter mounting ring 31 is detached and fixed to the mounting plate 5 by screws.

[0037] The inner wall of the main branch ring 32 is connected to the outer wall of the branch mounting ring 31. The setting angle between the branch mounting ring 31 and the main branch ring 32 is less than 180°. The main branch ring 32 is set on the branch mounting ring 31 to form an extended conical surface.

[0038] Branching holes 4 are formed on branching mounting ring 31 and branching main ring 32. Some branching holes 4 are formed on branching mounting ring 31, and the branching holes 4 on branching mounting ring 31 are evenly arranged along the circumference of branching mounting ring 31. Other branching holes 4 are formed on branching main ring 32, and the branching holes 4 on branching main ring 32 are evenly arranged along the circumference of branching main ring 32.

[0039] The number of branch holes 4 on the main branch ring 32 is greater than the number of branch holes 4 on the branch mounting ring 31. In this embodiment, there are a total of 30 branch holes 4, of which 24 branch holes 4 are opened on the main branch ring 32 and the other 6 branch holes 4 are opened on the branch mounting ring 31; each branch hole 4 on the branch mounting ring 31 can be at the same angle as one of the branch holes 4 on the main branch ring 32.

[0040] Each of the wire splitting holes 4 is equipped with a friction-reducing component. In this embodiment, the friction-reducing component is a tungsten steel mold. The friction-reducing component is installed on the wire splitting plate 3. The friction-reducing component can reduce the wear of the wire core passing through the wire splitting hole 4.

[0041] The implementation principle of the branching device for manufacturing nuclear power instrument cables using a cable cage stranding machine according to an embodiment of this application is as follows: During operation, core one passes through the hollow shaft of the stranding body and enters the wire pressing die via the core branching component 1. Subsequently, core one, core two, and core three pass through the stranding body and reach the branching plate 3 with 30 branching holes 4. Core one, core two, and core three pass through three branching holes 4 on the main branching ring 32. At this time, the three branching holes 4 that are passed through the main branching ring 32 correspond to three branching holes 4 on the branching mounting ring 31. At this time, filler core 1, filler core 2, and filler core 3 also pass through the stranded body and the line to reach the branch plate 3 with 30 branch holes 4. Then, filler core 1, filler core 2, and filler core 3 pass through the three branch holes 4 on the corresponding branch mounting ring 31. At this time, wire core 1, wire core 2, and wire core 3 are at the same angle as the corresponding filler core 1, filler core 2, and filler core 3. Wire core 1, wire core 2, and wire core 3 directly enter the pressure die by rotation, while filler core 1, filler core 2, and filler core 3 need to pass through the three-part inner filler branch device to enter the pressure die.

[0042] Similarly, the production requirements stipulate that there is one filler core on each side of the intersection of the wire cores, and there must be another filler core in the middle of the four filler cores. This structure requires five filler cores in the center of the four wire cores and four filler cores on the outside. It is only necessary to replace the three-equal filler core dividing piece 1 with the four-equal filler core dividing piece 1, change the three wire cores to four wire cores, and then increase the number of filler cores by one. The required structure can be produced by following the same steps.

[0043] The instrumentation cables inside the nuclear power plant are manufactured with a compact structure, avoiding the use of the secondary branch plate 3, saving space. Furthermore, the branch plate 3 rotates synchronously with the rotating strand, which facilitates the entry of the wire core and filler wire core into the filler branch piece 1 and subsequent processing steps in the required order.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
