Description

Technical Field

[0001] This invention relates to the field of silicon core tube technology, and in particular to an underground communication silicon core tube with an anti-settlement compensation section structure. Background Technology

[0002] Underground communication silicon core tubes are currently the mainstream pipe material for long-distance optical cable transmission projects. The core adopts a composite structure of "HDPE outer layer + silicone inner core". HDPE, as the main material of silicon core tubes, has good low temperature resistance, impact resistance and environmental stress cracking resistance, but it has defects such as insufficient heat resistance, easy creep under long-term load and low ring stiffness. High-performance polypropylene (PP) material has advantages such as high modulus, good heat resistance, creep resistance and dimensional stability, which can make up for the rigidity and heat resistance shortcomings of HDPE. Therefore, HDPE and high-performance polypropylene are generally blended and compounded.

[0003] Most existing silicon core tubes adopt a one-piece molding structure. When the tube body is partially damaged, it is impossible to replace the damaged section. Instead, the damaged section and a long area of ​​the silicon core tube around it must be disassembled and replaced as a whole. This not only makes the construction process complicated and the workload large, but also causes long-term interruption of communication lines, which greatly increases the construction period. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an underground communication silicon core pipe with a subsidence compensation section structure.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an underground communication silicon core tube with a subsidence compensation section structure, comprising a core tube mechanism, the core tube mechanism comprising a core assembly and a connecting assembly, the core assembly comprising two tube bodies, both of which have a corrugated structure and a certain degree of elasticity, and two inserts respectively fixed to the two end faces of one of the tube bodies, the end faces of the two tube bodies being close to each other are fitted together, and the end face of the other tube body is provided with a slot for insertion into the insert, the slot being made of α-olefin ethylene copolymer, the number of slots being equal to the number of inserts and their positions corresponding one-to-one.

[0006] By adopting the above technical solution, the damaged tube is first removed from the communication cable. Then, the two tubes are separated and moved to the damaged cable. The two tubes are then fitted together, and the insert is inserted into the slot. At this point, the damaged cable is located in the space between the two tubes. Finally, the connecting assembly is used to connect the installed tube to the original silicon core tubes on both sides of the damaged cable along its length. Compared to the existing one-piece molding method, this reduces the difficulty of replacing the damaged silicon core tube. Furthermore, only the damaged part needs to be replaced, simplifying the construction process, reducing workload, and shortening the construction cycle. In addition, a hot-melt device can be used to fit the outer wall of the tube and heat and melt the insert, allowing the solidified insert to connect tightly to the inner wall of the slot, increasing the stability of the connection between the two tubes. In this application, the tube body has a corrugated structure. The wave-shaped design of the corrugated structure can efficiently absorb multi-dimensional displacements such as vertical settlement, axial tension / compression, horizontal offset, and angular deflection through its own elastic deformation. It can constrain all the deformation caused by settlement within the corrugated structure body, thereby reducing the probability of fiber breakage and transmission degradation caused by deformation stress being transmitted to the internal optical cable.

[0007] Furthermore, the connecting assembly includes a first arc plate fixed to one end of the tube and coaxially arranged with the tube. The number of the first arc plates is equal to the number of tubes and their positions correspond one-to-one. The end faces of two first arc plates are close to each other and are fitted together. The connecting assembly also includes a metal tube fixed between the two first arc plates and coaxially arranged with the first arc plates, and a second arc plate fixed to the other end of the tube and coaxially arranged with the tube. The end faces of two second arc plates are close to each other and are fitted together. Both the first arc plate and the second arc plate are made of easily fusible adhesive material. The two ends of the slot extend to the end of the first arc plate on the same side away from the tube and the end of the second arc plate on the same side away from the tube, respectively. The two ends of the insert extend to the end of the first arc plate on the same side away from the tube and the end of the second arc plate on the same side away from the tube, respectively.

[0008] By adopting the above technical solution, firstly, the two tubes are attached together, and at the same time, the two second arc plates are attached to the metal tube on the original silicon core tube at one end of the cable length direction at the damaged point, and the two first arc plates are attached to the metal tube on the original silicon core tube at the other end of the cable length direction at the damaged point. Then, the hot melt equipment is used to heat and melt the first arc plates and the second arc plates respectively. After solidification, the first arc plates and the second arc plates can be more tightly connected to the corresponding metal tubes with greater stability.

[0009] Furthermore, the tube body includes an outer tube layer, a molten layer disposed on the end face of the outer tube layer, and a silicon core layer disposed on the arc-shaped sidewall of the outer tube layer. The outer tube layer is made of high-performance polypropylene and HDPE melt blend to improve the overall temperature resistance. The molten layer is made of α-olefin ethylene copolymer with a melting point of 50–100℃ and is easy to melt and bond.

[0010] By adopting the above technical solution, when the hot melt equipment is installed on the pipe body and heated and melted, it only needs to ensure that the temperature is controlled at 50-100℃. The outer pipe layer is made of high-performance polypropylene and HDPE melt blend, and its melting point can reach 160℃. This ensures the integrity of the outer pipe layer when the melt layer is melted and fixed.

[0011] Furthermore, the inner wall of the first arc plate is fixed with an arc strip coaxially arranged with the first arc plate, and the side wall of the metal tube is provided with an annular groove for inserting the arc strip. The outer side wall of the end of the metal tube facing the second arc plate is provided with a frustum-shaped guide section. The outer diameter of the frustum-shaped guide section gradually decreases from the middle of the tube body to the direction of the metal tube, and the inner diameter of the second arc plate gradually increases from the middle of the tube body to the direction of the metal tube.

[0012] By adopting the above technical solution, when the first arc plate is attached to the metal tube, the arc strip is inserted into the annular groove. The arc strip and the annular groove provide good limiting for the first arc plate, which helps to reduce the probability of axial displacement when the first arc plate is connected to the metal tube. A frustum is provided on the side wall of the metal tube. The outer diameter of the frustum-shaped guide section gradually decreases from the middle of the tube body to the metal tube, and the inner diameter of the second arc plate gradually increases from the middle of the tube body to the metal tube. This facilitates the initial installation and docking of the entire silicon core tube, where the two second arc plates are fitted onto the outer wall of the metal tube, making the docking of the silicon core tube easier.

[0013] Furthermore, the underground communication silicon core tube with the anti-settlement compensation section structure is connected using a docking device. The docking device includes a movable frame, a movable mechanism mounted on the movable frame, and a lifting mechanism mounted on the movable mechanism. The movable mechanism includes an installation component, which includes a crossbeam slidably mounted on the top of the movable frame, a linear module mounted on the bottom of the crossbeam, and a mounting frame fixed to the movable end of the linear module. The mounting frame is provided with two sets of clamping mechanisms for clamping the outer walls of the first and second arc plates, respectively. The lifting mechanism is used to drive the linear module to rise and fall. The movable mechanism also includes a movable component for driving the crossbeam to move.

[0014] By adopting the above technical solution, the clamping mechanism first clamps the first and second arc plates of the assembled silicon core tube to be installed, and in conjunction with the lifting and moving mechanisms, moves the silicon core tube to the bottom wall of the installation pit. Then, the workers use a special fixing seat to fix the silicon core tube. Subsequently, the moving, lifting, and clamping mechanisms are operated to move another silicon core tube to one end of the previous silicon core tube, and the metal tube on the clamped silicon core tube is aligned with the inner wall of the second arc plate on the silicon core tube in the pit. This completes the automatic docking between the two silicon core tubes. Compared with the existing manual docking method, this method is more efficient and reduces the labor intensity of workers.

[0015] Furthermore, two limiting through holes symmetrically arranged about the cross frame are provided through the side wall of the cross frame. The number of moving components is equal to the number of limiting through holes and their positions correspond one-to-one. The moving components include a moving motor fixed to the cross frame, a rack fixed to the top frame of the moving frame, a connecting rod that is provided through the side wall of the limiting through hole and rotatably connected to the cross frame, a moving gear fixedly sleeved on the connecting rod and meshing with the rack, and two limiting wheels that are rotatably installed in the limiting through holes and rollingly connected to the top of the moving frame. The side wall of the limiting wheel is provided with a recess, and the rack passes through the recess of the limiting wheel and engages with it.

[0016] By adopting the above technical solution, the linear module moves its moving end along the length of the pipeline, which in turn drives the mounting bracket fixed to the moving end of the linear module and the clamping mechanism set on the mounting bracket to move synchronously. In addition, the moving motor drives the connecting rod to rotate, which in turn drives the moving gear fixed to the connecting rod to rotate synchronously. Since the moving gear meshes with the rack, it can drive the connecting rod fixed to the moving gear, the moving motor connected to the connecting rod, and the crossbeam fixed to the moving motor to move horizontally along the vertical direction of the pipeline length, thereby realizing the horizontal bidirectional movement of the silicon core tube.

[0017] Furthermore, the lifting mechanism includes a lifting assembly and a rotating assembly. The lifting assembly includes a drive housing fixed to the top of the crossbeam, an internally threaded tube passing through the top of the crossbeam and rotatably connected to the crossbeam, a threaded post fixed to the top of the linear module, and a vertical rod fixed to the top of the linear module. The upper end of the internally threaded tube passes through the top of the drive housing and is rotatably connected to the drive housing. The threaded post passes through the internally threaded tube and is threadedly connected. The vertical rod passes through the top of the crossbeam and is slidably engaged with the crossbeam. The rotating assembly includes a rotary motor fixed to the top of the drive housing. The output end of the rotary motor passes through the top of the drive housing and is rotatably connected to the drive housing. The rotating assembly also includes a drive gear fixedly sleeved on the output end of the rotary motor and a driven gear fixedly sleeved on the internally threaded tube and meshing with the drive gear.

[0018] By adopting the above technical solution, when the rotary motor is working, it drives the drive gear to rotate, which in turn drives the driven gear meshing with the drive gear and the internally threaded tube fixed to the driven gear to rotate synchronously. According to the change of the rotation direction of the output end of the rotary motor, and under the limit of the vertical rod, the threaded column connected to the internally threaded tube and the linear module fixed to the threaded column can be raised and lowered, thereby changing the height of the silicon core tube.

[0019] Furthermore, the clamping mechanism is provided in two sets and symmetrically arranged about the center of the mounting frame. The clamping mechanism includes a clamping assembly, which includes an annular block fixed to the bottom of the mounting frame, a first clamping block slidably disposed on the annular block, a second clamping block slidably disposed on the annular block, and two rubber sheets respectively fixed to the sidewalls of the first clamping block and the second clamping block that are close to each other. The sidewalls of the two rubber sheets that are close to each other are in close contact with the sidewalls of the two first arc plates that are far apart from each other. The sidewalls of the other two rubber sheets that are close to each other are in close contact with the sidewalls of the two second arc plates that are far apart from each other. The clamping mechanism also includes a distance adjustment assembly for adjusting the distance between the first clamping block and the second clamping block.

[0020] By adopting the above technical solution, the moving mechanism and lifting mechanism are operated to move the silicon core tube clamped on the clamping mechanism into the installation pit. Then, the distance adjustment component is operated to gradually increase the distance between the first clamping block and the second clamping block until the rubber sheets on both sides separate from the second arc plate and the first arc plate, respectively. At this time, the moving mechanism and lifting mechanism are operated again to move the clamping mechanism to the position of another silicon core tube, and make the rubber sheets on both sides fit with the second arc plate and the first arc plate on the silicon core tube, respectively. Then, the moving mechanism and lifting mechanism are operated again to dock the two silicon core tubes. By repeating the above steps, the overall docking work can be completed.

[0021] Furthermore, the adjusting assembly includes a crossbar fixed inside the annular block and slidingly engaged with the first clamping block and the second clamping block, a bidirectional threaded rod rotatably installed inside the annular block, and an adjusting motor fixed on the annular block and driving the bidirectional threaded rod to rotate. The bidirectional threaded rod is provided with two sections of threads with opposite directions and equal pitch. The first clamping block and the second clamping block are respectively provided on the two sections of threads and threadedly connected.

[0022] By adopting the above technical solution, when the motor is working, it drives the bidirectional threaded rod to rotate. Under the limit of the crossbar, and with two sections of threads with opposite directions and equal pitch on the bidirectional threaded rod, the first clamping block and the second clamping block are respectively set on the two sections of threads and threadedly connected, so that the first clamping block and the second clamping block move closer or further away from each other, thereby realizing the clamping or releasing operation of the silicon core tube.

[0023] Furthermore, the movable frame is fixed with two placement boxes, both of which are open at the top and have a hollow structure. The side walls on both sides of the placement boxes are provided with limiting through holes for the first arc plate and the second arc plate to pass through, respectively. The diameter of the second arc plate is smaller than the diameter of the circle formed by the two tubes.

[0024] By adopting the above technical solution, the operating mechanism and lifting mechanism enable the clamping mechanism to clamp and connect the silicon core tubes placed in the placement box. There are two placement boxes. After the silicon core tubes in one placement box are connected, the clamping mechanism can be operated to clamp and use the silicon core tubes in the other placement box. At the same time, the lifting equipment can be used to put the silicon core tubes to be installed back into the empty placement box so that the device can continuously connect.

[0025] In summary, the present invention has the following beneficial effects: In this application, by improving the existing structure, the difficulty of replacing damaged silicon core tubes is reduced compared with the existing one-piece molding method. At the same time, only the damaged ones need to be replaced, the construction process is simple, the workload is small, and the construction cycle is reduced. In addition, the corrugated structure can reduce the probability of fiber breakage and transmission degradation caused by deformation stress transmitted to the internal optical cable.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-5As shown in the illustration, this application discloses an underground communication silicon core tube with a subsidence compensation section structure, including a core tube mechanism 1. The core tube mechanism 1 includes a core assembly 11 and a connecting assembly 12. The core assembly 11 includes a tube body 111 and inserts 112. Two tube bodies 111 are provided. Both tube bodies 111 have a corrugated structure and a certain degree of elasticity. The end faces of the two tube bodies 111 are close to each other and fit together. The end face of the other tube body 111 has a slot 3 for insertion into the insert 112. The slot 3 is made of α-olefin ethylene copolymer. The number of slots 3 is equal to the number of inserts 112 and their positions correspond one-to-one. Two inserts 112 are provided, and the two inserts 112 are respectively fixed to the two end faces of one of the tube bodies 111. First, the damaged tube 111 is removed from the communication cable. Then, the two tubes 111 are separated and moved to the damaged cable. The two tubes 111 are then fitted together, and the insert 112 is inserted into the slot 3. At this point, the damaged cable is located in the space between the two tubes 111. Finally, the connecting assembly 12 is used to connect the installed tube 111 to the original silicon core tubes on both sides of the damaged cable along its length. Compared to the existing one-piece molding method, this reduces the difficulty of replacing the damaged silicon core tube. In addition, a hot-melt device can be used to fit the outer wall of the tube 111 and heat and melt the insert 112, so that the solidified insert 112 can be tightly connected to the inner wall of the slot 3, thereby increasing the connection stability between the two tubes 111. In this application, the tube body 111 has an overall corrugated structure. The wave-shaped design of the corrugated structure can efficiently absorb multi-dimensional displacements such as vertical settlement, axial tension / compression, horizontal offset, and angular deflection through its own elastic deformation. It can constrain all the deformation caused by settlement within the corrugated structure body, thereby reducing the probability of fiber breakage and transmission degradation caused by deformation stress being transmitted to the internal optical cable.

[0030] The connecting assembly 12 includes a first arc plate 121, a metal tube 122, and a second arc plate 123. The first arc plate 121 is fixed to one end of the tube body 111 and is coaxially arranged with the tube body 111. The number of first arc plates 121 is equal to the number of tube bodies 111, and their positions correspond one-to-one. The end faces of the two first arc plates 121 are close to each other and fit together. The two ends of the insert 112 extend to the end of the first arc plate 121 on the same side away from the tube body 111 and the end of the second arc plate 123 on the same side away from the tube body 111, respectively. The metal tube 122 is fixed between the two first arc plates 121 and is coaxially arranged with the first arc plate 121. The second arc plate 123 is fixed to the other end of the tube body 111 and is coaxially arranged with the tube body 111. The two second arc plates 123 are attached to each other at their close end faces. Both the first arc plate 121 and the second arc plate 123 are made of easily fusible adhesive material. The two ends of the slot 3 extend to the end of the first arc plate 121 on the same side away from the tube body 111 and the end of the second arc plate 123 on the same side away from the tube body 111, respectively. First, the two tube bodies 111 are attached together, and at the same time, the two second arc plates 123 are attached to the metal tube 122 on the original silicon core tube at one end of the cable length direction at the damaged point, and the two first arc plates 121 are attached to the metal tube 122 on the original silicon core tube at the other end of the cable length direction at the damaged point. Then, the hot melt equipment is used to heat and melt the first arc plate 121 and the second arc plate 123 respectively. After solidification, the first arc plate 121 and the second arc plate 123 can be more tightly and stably connected to the corresponding metal tube 122.

[0031] The tube body 111 includes an outer tube layer 1111, a molten layer 1112, and a silicon core layer 1113. The outer tube layer 1111 is made of high-performance polypropylene and HDPE melt blend to improve the overall temperature resistance. The molten layer 1112 is made of α-olefin ethylene copolymer with a melting point of 50–100℃, which is easy to melt and bond. The molten layer 1112 is disposed on the end face of the outer tube layer 1111, and the silicon core layer 1113 is disposed on the arc-shaped sidewall of the outer tube layer 1111. When the hot-melt equipment is installed on the tube body 111 and heated and melted, it only needs to ensure that the temperature is controlled at 50–100℃. The outer tube layer 1111, made of high-performance polypropylene and HDPE melt blend, has a melting point that can reach 160℃, which can ensure the integrity of the outer tube layer 1111 when the molten layer 1112 is melted and fixed.

[0032] The inner wall of the first arc plate 121 is fixed with an arc strip 4 coaxially arranged with the first arc plate 121. An annular groove 5 is formed on the side wall of the metal tube 122 to engage with the arc strip 4. A frustum is formed on the side wall of the metal tube 122. The outer diameter of the frustum-shaped guide section gradually decreases from the middle of the tube body 111 to the metal tube 122. The inner diameter of the second arc plate 123 gradually increases from the middle of the tube body 111 to the metal tube 122. When the first arc plate 121 and the metal tube 122 are in contact, the arc strip 4 is inserted into the annular groove 5. The arc strip 4 and the annular groove 5 provide good positioning for the first arc plate 121, which helps reduce the probability of axial displacement when the first arc plate 121 is connected to the metal tube 122. The metal tube 122 has a frustum on its side wall. The outer diameter of the frustum-shaped guide section gradually decreases from the middle of the tube body 111 to the metal tube 122. The inner diameter of the second arc plate 123 gradually increases from the middle of the tube body 111 to the metal tube 122. This facilitates the connection of the two second arc plates 123 onto the outer wall of the metal tube 122 during the initial installation and docking of the overall silicon core tube.

[0033] like Figure 6-12 As shown, an underground communication silicon core pipe with a settlement compensation section structure is connected using a docking device. Specifically, the docking device includes a movable frame 6, a movable mechanism 7, a lifting mechanism 8, and a clamping mechanism 10. The movable mechanism 7 is mounted on the movable frame 6. The movable mechanism 7 includes an installation component 71 and a movable component 72. The installation component 71 includes a crossbeam 711, a linear module 712, and a mounting bracket 713. Two limiting through holes 9 are symmetrically arranged about the side wall of the crossbeam 711. The crossbeam 711 is slidably mounted on the top of the movable frame 6. The linear module 712 is located at the bottom of the crossbeam 711, and the mounting bracket 713 is fixed to the movable end of the linear module 712. First, the clamping mechanism 10 is operated to clamp the first arc plate 121 and the second arc plate 123 of the assembled silicon core tube to be installed. With the help of the lifting mechanism 8 and the moving mechanism 7, the silicon core tube is moved to the bottom wall of the installation pit. Then, the workers use a special fixing seat to fix the silicon core tube. Subsequently, the moving mechanism 7, the lifting mechanism 8 and the clamping mechanism 10 are operated to move another silicon core tube to one end of the previous silicon core tube. The metal tube 122 on the clamped silicon core tube is then connected to the inner wall of the second arc plate 123 on the silicon core tube in the pit. This completes the automatic docking between the two silicon core tubes. Compared with the existing manual docking method, this method is more efficient and reduces the labor intensity of workers.

[0034] The number of moving components 72 is equal to the number of limiting through holes 9, and their positions correspond one-to-one. Moving components 72 are used to drive the crossbeam 711 to move. Each moving component 72 includes a moving motor 721, a rack 722, a connecting rod 723, a moving gear 724, and limiting wheels 725. The moving motor 721 is fixed to the crossbeam 711, and the rack 722 is fixed to the top frame of the moving frame 6. The connecting rod 723 passes through the side wall of the limiting through hole 9 and is rotatably connected to the crossbeam 711. The moving gear 724 is fixedly sleeved on the connecting rod 723 and meshes with the rack 722. Two limiting wheels 725 are provided. The two limiting wheels 725 are rotatably installed in the limiting through hole 9 and are rollingly connected to the top of the moving frame 6. Recesses are provided on the side walls of the limiting wheels 725, and the rack 722 passes through and engages with these recesses. When the linear module 712 operates, its moving end moves along the length of the pipeline, which in turn drives the mounting bracket 713 fixed to the moving end of the linear module 712 and the clamping mechanism 10 set on the mounting bracket 713 to move synchronously. In addition, the moving motor 721 operates to drive the connecting rod 723 to rotate, which in turn drives the moving gear 724 fixed to the connecting rod 723 to rotate synchronously. Since the moving gear 724 meshes with the rack 722, it can drive the connecting rod 723 fixed to the moving gear 724, the moving motor 721 connected to the connecting rod 723, and the crossbeam 711 fixed to the moving motor 721 to move horizontally along the vertical direction of the pipeline length, thereby realizing the horizontal bidirectional movement of the silicon core tube.

[0035] A lifting mechanism 8 is mounted on the moving mechanism 7 and is used to drive the linear module 712 to rise and fall. The lifting mechanism 8 includes a lifting assembly 81 and a rotating assembly 82. The lifting assembly 81 includes a drive housing 811, an internally threaded tube 812, a threaded post 813, and a vertical rod 814. The drive housing 811 is fixed to the top of the crossbeam 711. The internally threaded tube 812 passes through the top of the crossbeam 711 and is rotatably connected to it. The upper end of the internally threaded tube 812 passes through the top of the drive housing 811 and is rotatably connected to it. The threaded post 813 is fixed to the top of the linear module 712, passes through the internally threaded tube 812, and is threadedly connected. The vertical rod 814 is fixed to the top of the linear module 712, passes through the top of the crossbeam 711, and is slidably engaged with it. The rotating assembly 82 includes a rotary motor 821, a driving gear 822, and a driven gear 823. The rotary motor 821 is fixed to the top of the drive housing 811. The output end of the rotary motor 821 passes through the top of the drive housing 811 and is rotatably connected to the drive housing 811. The driving gear 822 is fixedly sleeved on the output end of the rotary motor 821, and the driven gear 823 is fixedly sleeved on the internally threaded tube 812 and meshes with the driving gear 822. When the rotary motor 821 is working, it drives the driving gear 822 to rotate, which in turn drives the driven gear 823 meshing with the driving gear 822 and the internally threaded tube 812 fixed to the driven gear 823 to rotate synchronously. According to the change of the rotation direction of the output end of the rotary motor 821, and under the limitation of the vertical rod 814, the threaded post 813 threaded to the internally threaded tube 812 and the linear module 712 fixed to the threaded post 813 can be raised and lowered, thereby changing the height of the silicon core tube.

[0036] A clamping mechanism 10 is mounted on the mounting bracket 713, and two sets of limiting through holes 9 are provided. The two sets of clamping mechanisms 10 are used to clamp the outer walls of the first arc plate 121 and the second arc plate 123, respectively. Each clamping mechanism 10 includes a clamping assembly 101 and an adjusting assembly 102. The clamping assembly 101 includes an annular block 1011, a first clamping block 1012, a second clamping block 1013, and rubber sheets 1014. The annular block 1011 is fixed to the bottom of the mounting bracket 713. The first clamping block 1012 is slidably mounted on the annular block 1011, and the second clamping block 1013 is slidably mounted on the annular block 1011. Two rubber sheets 1014 are provided, and the two rubber sheets 1014 are respectively fixed to the side walls of the first clamping block 1012 and the second clamping block 1013 that are close to each other. The side walls of the two rubber sheets 1014 that are close to each other are in close contact with the side walls of the two first arc plates 121 that are far apart from each other. The sidewalls of the two rubber sheets 1014 that are close to each other are pressed against the sidewalls of the two second arc plates 123 that are far apart from each other. The moving mechanism 7 and the lifting mechanism 8 are operated to move the silicon core tube clamped on the clamping mechanism 10 into the installation pit. Then, the distance adjustment component 102 is operated to gradually increase the distance between the first clamping block 1012 and the second clamping block 1013 until the rubber sheets 1014 on both sides separate from the second arc plate 123 and the first arc plate 121, respectively. At this point, the moving mechanism 7 and the lifting mechanism 8 are operated again to move the clamping mechanism 10 to the position of another silicon core tube, and the rubber sheets 1014 on both sides are pressed against the second arc plate 123 and the first arc plate 121 on that silicon core tube, respectively. Then, the moving mechanism 7 and the lifting mechanism 8 are operated again to connect the two silicon core tubes. By repeating the above steps, the overall connection work can be completed.

[0037] The adjusting assembly 102 is used to adjust the distance between the first clamping block 1012 and the second clamping block 1013. The adjusting assembly 102 includes a crossbar 1021, a bidirectional threaded rod 1022, and an adjusting motor 1023. The crossbar 1021 is fixed inside the annular block 1011 and slides in cooperation with the first clamping block 1012 and the second clamping block 1013. The bidirectional threaded rod 1022 is rotatably mounted inside the annular block 1011. The bidirectional threaded rod 1022 is provided with two sections of threads with opposite directions and equal pitch. The first clamping block 1012 and the second clamping block 1013 are respectively disposed on the two sections of threads and threadedly connected. The adjusting motor 1023 is fixed on the annular block 1011 and drives the bidirectional threaded rod 1022 to rotate. When the adjusting motor 1023 is working, it drives the bidirectional threaded rod 1022 to rotate. Under the limit of the crossbar 1021, and with two sections of threads with opposite directions and equal pitch on the bidirectional threaded rod 1022, the first clamping block 1012 and the second clamping block 1013 are respectively set on the two sections of threads and threadedly connected, so that the first clamping block 1012 and the second clamping block 1013 move closer or further away from each other, thereby realizing the clamping or releasing operation of the silicon core tube.

[0038] Two hollow placement boxes 13, both with open tops, are fixed on the movable frame 6. Each placement box 13 has a limiting through hole 14 on its side walls for the passage of a first arc plate 121 and a second arc plate 123, respectively. The diameter of the second arc plate 123 is smaller than the diameter of the circle formed by the two tubes 111. Operating the moving mechanism 7 and the lifting mechanism 8 allows the clamping mechanism 10 to clamp and connect the silicon core tubes placed in the placement boxes 13. Since there are two placement boxes 13, after the silicon core tubes in one placement box 13 are connected, the clamping mechanism 10 can be operated to clamp and use the silicon core tube in one of the placement boxes 13. Simultaneously, a lifting device can be used to reposition the silicon core tube to be installed into the empty placement box 13, enabling continuous connection operations.
