Description

Technical Field

[0001] This invention relates to the field of protective tube technology, and in particular to a cable protective tube with a heat dissipation structure. Background Technology

[0002] With the rapid development of urban power grid upgrades, municipal underground pipeline construction, rail transit, and new energy power projects, the scale and mileage of underground power cable laying have continued to grow. As a core protective component in underground cable laying systems, cable protection pipes are mainly used to provide mechanical protection for cables and isolate them from soil corrosion and external damage. Their structural performance, heat dissipation capacity, and ease of installation directly determine the operational stability, service life, and construction efficiency of power cables, making them one of the key components ensuring the safe and reliable operation of power transmission systems.

[0003] Chinese invention patent CN120534013A discloses a high-strength cable protection pipe. The high-strength cable protection pipe comprises, from the outside to the inside, a protective layer 1 and a deformable heat-conducting layer 2. The protective layer 1, by weight, comprises 60-80 parts polypropylene, 5-8 parts anti-wear agent, 3-5 parts antioxidant, 5-8 parts external oxide powder, 5-8 parts toughening agent, and 3-5 parts talc powder. The deformable heat-conducting layer 2, by weight, comprises 30-40 parts supporting material, 5-8 parts internal oxide powder, and 20-30 parts silicone oil. The composition includes 20-30 parts of zirconium tungstate and 10-20 parts of support material. The wear-resistant agent is one or more of polytetrafluoroethylene micro powder, graphite, glass fiber and carbon fiber. The antioxidant is one or more of phosphite ester and 2,6-di-tert-butylphenol. The external oxide powder is one or more of alumina, copper oxide and iron oxide. The toughening agent is one of EPDM rubber and butadiene rubber. The support material is one or more of kaolinite or montmorillonite. The internal oxide is one or more of alumina, copper oxide and iron oxide.

[0004] Existing cable protection pipes generally adopt a single hollow cavity structure. When multiple cables are laid in the same pipe, the cables are very likely to stack and entangle with each other, which greatly reduces the ventilation gap between the cables and significantly worsens the air circulation inside the pipe. The heat generated by the cables during operation is very likely to accumulate in the stacked area, forming local high-temperature hot spots, which further aggravates the risk of overheating and damage to the cables. Summary of the Invention

[0005] To address the above problems, the present invention provides a cable protection pipe with a heat dissipation structure.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a cable protection pipe with a heat dissipation structure, including a protective pipe body, a spiral groove is provided on the side wall of the protective pipe body, a plurality of vent holes are provided through the surface of the spiral groove, a connecting pipe is provided inside the protective pipe body and coaxially arranged with the protective pipe body, a plurality of partitions are fixed on the side wall of the connecting pipe, and a connecting component is provided on the protective pipe body for fixing two adjacent protective pipe bodies together.

[0007] By adopting the above technical solution, the protective pipe is installed in the installation pit, and the cable passes through the space between two adjacent partitions. When the cable is in normal power supply, the heat generated by the cable will be dissipated through the ventilation holes opened on the surface of the spiral groove, which increases the speed of heat dissipation and reduces the probability of cable damage caused by excessive temperature. At the same time, multiple partitions separate multiple cables, avoiding the accumulation between cables, which would reduce the gap between cables and cause poor air circulation and heat dissipation. It also reduces the probability of cable damage caused by excessive local temperature due to accumulation.

[0008] Furthermore, the connecting assembly includes a first connecting pipe fixed to one end of the protective pipe body, a threaded pipe fixed to the end of the first connecting pipe away from the protective pipe body, and a second connecting pipe fixed to the other end of the protective pipe body. The first connecting pipe, the threaded pipe, the second connecting pipe, and the protective pipe body are all coaxially arranged. The end of the second connecting pipe away from the protective pipe body is provided with a threaded groove that is threadedly connected to the threaded pipe.

[0009] By adopting the above technical solution, the threaded pipe on one of the protective pipes is threadedly connected to the threaded groove of another protective pipe until the end face of the first connecting pipe of the former protective pipe is pressed against the end face of the second connecting pipe of the latter. By following the above steps, the docking and installation of multiple protective pipes can be completed.

[0010] Furthermore, spiral strips made of a material with high thermal conductivity are fixed on the side walls on both sides of the spiral groove. An anti-clogging plate is spirally wound inside the spiral groove. The anti-clogging plate is provided with two protrusions. Both spiral strips are provided with recesses. The two recesses are respectively inserted into the two protrusions.

[0011] By adopting the above technical solution, heat passes through the vent holes and enters the cavity formed between the spiral strip, the anti-clogging plate, and the spiral groove. Then, the heat is transferred by the spiral strip to the soil around the protective pipe. The spiral strip and the anti-clogging plate prevent the soil from clogging the vent holes.

[0012] Furthermore, the anti-clogging plate includes an outer layer and an inner layer fixed to the side wall of the outer layer near the protective tube body. The outer layer is made of a heat-resistant material, the inner layer is made of an α-olefin ethylene copolymer, and the protective tube body is made of poly(4-methylpentene-1), metallocene polyolefin, and HDPE material to increase the overall heat dissipation effect of the protective tube body.

[0013] By adopting the above technical solution, after the anti-clogging plate and the spiral strip are inserted, the inner layer is melted using a hot-melt device. After the inner layer solidifies, it can form a tight connection with the spiral strip, which helps to improve the stability of the connection between the spiral strip and the anti-clogging plate. In addition, the protective tube body is composed of poly-methylpentene, metallocene polyolefin, and HDPE materials. Among them, the poly-methylpentene and metallocene polyolefin materials are conducive to the heat transfer inside the protective tube, thereby increasing the overall heat dissipation effect of the protective tube.

[0014] Furthermore, the cable protection pipe with a heat dissipation structure is installed using an installation device. The installation device includes a moving mechanism and an installation mechanism. The moving mechanism includes a moving component, which includes an electric flatbed cart located at the bottom of the installation pit of the protection pipe, a moving box slidably located on the top of the electric flatbed cart, two rotating rods that are both inserted through the moving box and rotatably connected to the moving box, and concave wheels fixedly sleeved on the rotating rods. The electric flatbed cart is equipped with multiple lifting rings so that the moving mechanism and the installation mechanism can be moved away from or into the installation pit after use or before use. Each rotating rod is equipped with two concave wheels. The installation mechanism is located on the moving box and is used to clamp and rotate the protection pipe to be installed. The moving mechanism also includes a displacement component for driving the moving box to move.

[0015] By adopting the above technical solution (for ease of description, the protective pipes are sequentially labeled as the first protective pipe, the second protective pipe, etc., and the clamp mounting seats are referred to as the first mounting seat, the second mounting seat, etc.), firstly, two first mounting seats are installed on the inner bottom wall of the installation pit. Then, the first protective pipe is passed through the inside of the clamps of the two first mounting seats, and the clamps of the first mounting seats are used to fasten the first protective pipe. Subsequently, two second mounting seats are installed in the installation pit, located on one side of the length direction of the first protective pipe. The moving mechanism and the installation mechanism are moved to the installation pit, located on the second mounting seats away from the first protective pipe. The first protective pipe is positioned, and then the installation mechanism clamps the second protective pipe. Simultaneously, the moving box moves towards the first protective pipe, while the installation mechanism rotates the second protective pipe at a low speed. During this process, the second protective pipe passes through the clamp of the second mounting seat until its threaded groove connects with the threaded pipe of the first protective pipe. Finally, the installation mechanism releases the second protective pipe, and the moving box moves in the opposite direction until it returns to its original position. At the same time, the electric flatbed trolley moves the moving mechanism and installation mechanism away from the second protective pipe, thus completing the installation of the two protective pipes. Similarly, a third mounting seat is installed at the location between the electric flatbed trolley and the second protective pipe in the installation pit, and the installation of the third protective pipe is completed according to the above steps. This process is repeated until all protective pipes are installed.

[0016] Furthermore, the displacement assembly includes a drive rod rotatably mounted inside the moving box, a circular gear fixedly sleeved on the drive rod, a rack fixed to the top of the electric flatbed and meshing with the circular gear to form a T-shaped structure, and a driven bevel gear fixedly sleeved on the drive rod. A limiting through hole extending to the other side wall of the moving box is provided through the side wall of the moving box. The rack passes through the limiting through hole and slides in engagement. The rack passes through the recess of the concave wheel. The outer wall of the concave wheel is in rolling connection with the top of the horizontal section of the rack. The meshing groove of the rack is opened at the top of the vertical section of the rack. The moving mechanism also includes a rotating assembly for driving the driven bevel gear to rotate.

[0017] By adopting the above technical solution, the rotating component drives the driven bevel gear to rotate, which in turn drives the drive rod fixed to the driven bevel gear and the circular gear fixed to the drive rod to rotate synchronously. Since the circular gear meshes with the rack, it drives the drive rod and the movable box connected to the drive rod to move, thereby changing the position of the movable box. In addition, since a limiting through hole extending to the other side wall of the movable box is provided through the side wall of the movable box, the rack passes through the limiting through hole and slides in engagement. The rack passes through the recess of the concave wheel, and the outer wall of the concave wheel rolls with the top of the horizontal section of the rack, which helps to improve the stability of the movable box during movement.

[0018] Furthermore, the rotating assembly includes a motor fixed to the movable box, a worm gear fixedly mounted on the output end of the motor and coaxially arranged with the output end of the motor, and a driving bevel gear fixedly sleeved on the lower end of the worm gear and meshing with the driven bevel gear. The mounting mechanism includes a rotating assembly, which includes a drive tube that passes through the movable box and is rotatably connected to the movable box, a mounting shell fixed to the end of the drive tube away from the movable box and coaxially arranged with the drive tube, a worm wheel fixedly sleeved on the drive tube and meshing with the worm gear, and a clamping block that passes through the side wall of the mounting shell and slides in cooperation with the mounting shell. Multiple clamping blocks are provided and evenly distributed about the axis of the mounting shell. The mounting mechanism also includes an adjustment assembly for driving multiple clamping blocks to move in a direction away from the axis of the mounting shell.

[0019] By adopting the above technical solution, when the motor is working, it drives the worm to rotate, which in turn causes the driving bevel gear fixed to the worm and the driven bevel gear meshing with the driving bevel gear to rotate synchronously, ensuring the normal movement of the moving box. First, the mounting shell is inserted into the threaded tube of the protective tube. Then, the adjusting component is operated to drive multiple clamping blocks to move in a direction away from the axis of the mounting shell until the end face of the clamping block is in close contact with the inner wall of the threaded tube, thus achieving the clamping operation of the protective tube.

[0020] Furthermore, a sliding through hole is provided through the side wall of the mounting housing. The adjustment assembly includes a roller rotatably mounted on the side wall of the clamping block near the axis of the mounting housing, an adjustment block rotatably mounted inside the mounting housing and coaxially arranged with the mounting housing, a connecting rod fixed on the side wall of the adjustment block near the moving box and coaxially arranged with the adjustment block, and a slider fixed on the clamping block and slidably engaged with the sliding through hole. A protrusion is provided on the side wall of the adjustment block. The protrusion has an arc surface that is rotatably connected to the roller and eccentrically arranged with the connecting rod. The connecting rod passes through the drive tube and is rotatably connected with the drive tube. A slide rod that slidably engages with the slider is fixed inside the sliding through hole. A spring that extends and retracts along the direction of slider movement is fixed between the slider and the inner wall of the sliding through hole. The number of sliding through holes, sliders, rollers, protrusions, arc surfaces, slide rods, and springs are all equal and their positions correspond one-to-one. The mounting mechanism also includes an auxiliary component for facilitating the rotation of the connecting rod and locking it with the drive tube after rotation.

[0021] By adopting the above technical solution, the rotating connecting rod drives the adjusting block to rotate. Since the side wall of the adjusting block has a protrusion with an arc surface that rolls with the roller and is eccentrically positioned with the connecting rod, and the connecting rod passes through the drive tube and rotates with it, the roller, the clamping block rotatedly connected to the roller, and the slider fixed to the clamping block all move away from the axis of the adjusting block. Simultaneously, the spring is gradually stretched until the clamping block is pressed tightly against the inner wall of the threaded tube. Similarly, rotating the connecting rod in the opposite direction drives the adjusting block to rotate, and the spring gradually contracts and returns to its original position. This causes the roller, the clamping block rotatedly connected to the roller, and the slider fixed to the clamping block to move closer to the axis of the adjusting block and return to its original position, thus releasing the threaded tube from the clamp.

[0022] Furthermore, the auxiliary components include a handwheel slidably mounted on the connecting rod, a drive block fixed to the inner wall of the handwheel, and an insert rod fixed to one end of the handwheel near the drive tube. The side wall of the connecting rod has a drive groove for the drive block to slide into, and the side wall of the connecting rod has an annular groove that slides with the drive block and communicates with the drive groove. The end of the drive tube near the handwheel has a slot for inserting the insert rod. There are two slots, and the angle formed by the line connecting the center of one slot and the axis of the drive tube and the center of the other slot and the axis of the drive tube is equal to the angle formed between the two clamping blocks.

[0023] By adopting the above technical solution, pulling the handwheel away from the drive tube will cause both the drive block and the insertion rod fixed to the handwheel to move away from the drive tube until the drive block moves from the annular groove into the drive groove, and the insertion rod separates from the slot. At this time, rotating the handwheel will cause the connecting rod to rotate under the limit of the drive groove and the drive block until the insertion rod rotates to the position of another slot. At this time, the clamping block is just close to the inner wall of the threaded tube. Then, pushing the handwheel towards the drive tube will reduce the probability of the handwheel deflecting when the drive tube rotates.

[0024] Furthermore, the top of the electric flatbed cart is fixed with two placement seats, both of which have an arc-shaped top. Each placement seat has multiple ball bearings movably installed on the surface of its arc-shaped structure. A limit plate is fixed on the placement seat near the mobile box. A support plate is fixed on the top of the electric flatbed cart, and the drive tube passes through the side wall of the support plate and cooperates with it.

[0025] By adopting the above technical solution, the two ends of the protective tube are first connected to the arc structure of the two placement seats by the lifting equipment, and the outer wall of the protective tube is in contact with the surface of the ball bearing. At this time, the mounting shell is exactly coaxial with the threaded tube. When clamping the threaded tube, it is only necessary to move the moving box horizontally until the mounting shell moves into the threaded tube, which facilitates the clamping operation of the protective tube.

[0026] In summary, the present invention has the following beneficial effects: In this application, through improvements to the existing technology, multiple partitions separate and place multiple cables, avoiding the accumulation of cables, which would reduce the gaps between cables, resulting in poor air circulation and heat dissipation, and also reducing the probability of cable damage caused by excessive local temperature due to accumulation.

[0029] 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.

[0030] like Figure 1-4 As shown in the figure, this application discloses a cable protection pipe with a heat dissipation structure, including a protective pipe body 1 and a connecting component 5. A spiral groove 2 is formed on the side wall of the protective pipe body 1. Multiple vent holes are formed through the surface of the spiral groove 2. A connecting pipe 3 is arranged coaxially with the protective pipe body 1 inside the protective pipe body 1. Multiple partitions 4 are fixed to the side wall of the connecting pipe 3. The protective pipe body 1 is installed in the installation pit, and the cable passes through the space between two adjacent partitions 4. When the cable is in normal use, the heat generated by the cable will be dissipated through the vent holes formed on the surface of the spiral groove 2, which increases the heat dissipation speed and reduces the probability of cable damage due to excessive temperature. At the same time, the multiple partitions 4 separate multiple cables, avoiding the accumulation of cables, which would reduce the gap between cables and cause poor air circulation and heat dissipation. It also reduces the probability of cable damage due to localized excessive temperature caused by accumulation.

[0031] A connecting component 5 is mounted on the protective pipe body 1 and is used to fix two adjacent protective pipe bodies 1 together. The connecting component 5 includes a first connecting pipe 51, a threaded pipe 52, and a second connecting pipe 53. The first connecting pipe 51 is fixed to one end of the protective pipe body 1. The threaded pipe 52 is fixed to the end of the first connecting pipe 51 away from the protective pipe body 1. The second connecting pipe 53 is fixed to the other end of the protective pipe body 1. The first connecting pipe 51, the threaded pipe 52, the second connecting pipe 53, and the protective pipe body 1 are all coaxially arranged. The end of the second connecting pipe 53 away from the protective pipe body 1 has a threaded groove 54 for threaded connection with the threaded pipe 52. The threaded pipe 52 on one protective pipe is threadedly connected to the threaded groove 54 of another protective pipe until the end face of the first connecting pipe 51 of the previous protective pipe is pressed against the end face of the second connecting pipe 53 of the next protective pipe. By following these steps, the butt joint installation of multiple protective pipes can be completed.

[0032] Spiral strips 6 made of a material with high thermal conductivity are fixed to the side walls on both sides of the spiral groove 2. Anti-clogging plates 7 are spirally wound inside the spiral groove 2. Each anti-clogging plate 7 has two protrusions, and each of the two spiral strips 6 has a recess. The two recesses are respectively inserted into the two protrusions. Heat passes through the vent holes and enters the cavity formed between the spiral strips 6, the anti-clogging plates 7, and the spiral groove 2. Then, the heat is transferred from the spiral strips 6 to the soil surrounding the protective pipe. The spiral strips 6 and the anti-clogging plates 7 prevent the soil from clogging the vent holes.

[0033] The anti-clogging plate 7 comprises an outer layer 71 and an inner layer 72, with the inner layer 72 fixed to the side wall of the outer layer 71 near the protective tube body 1. The outer layer 71 is made of a heat-resistant material, and the inner layer 72 is made of an α-olefin ethylene copolymer. The protective tube body 1 is composed of poly(4-methylpentene-1), metallocene polyolefin, and HDPE to enhance the overall heat dissipation of the protective tube body 1. After the anti-clogging plate 7 is inserted into the spiral strip 6, the inner layer 72 is melted using a heat-melting device. Once the inner layer 72 solidifies, it forms a tight connection with the spiral strip 6, which improves the stability of the connection between the spiral strip 6 and the anti-clogging plate 7. Furthermore, the protective tube body 1 is composed of poly(4-methylpentene-1), metallocene polyolefin, and HDPE, where poly(4-methylpentene-1) and metallocene polyolefin facilitate heat transfer within the protective tube, thereby increasing the overall heat dissipation of the protective tube.

[0034] like Figure 5-11As shown, the cable protection pipe with a heat dissipation structure is installed using installation equipment, which includes a moving mechanism 8 and an installation mechanism 9. The moving mechanism 8 includes a moving component 81, a displacement component 82, and a rotating component 83. The moving component 81 includes an electric flatbed trolley 811, a moving box 812, a rotating rod 813, and a concave wheel 814. The electric flatbed trolley 811 is located at the bottom of the installation pit for the protection pipe. The electric flatbed trolley 811 is equipped with multiple lifting rings to allow the moving mechanism 8 and the installation mechanism 9 to be moved away from or into the installation pit before or after use. The moving box 812 is slidably mounted on the top of the electric flatbed trolley 811. A limiting through hole 10 extending to the other side wall of the moving box 812 is provided through the side wall of the moving box 812. Two rotating rods 813 are provided, both of which are provided through the moving box 812 and rotatably connected to the moving box 812. Each rotating rod 813 is equipped with two concave wheels 814, which are fixedly sleeved on the rotating rod 813. (For ease of description, the protective pipes are sequentially labeled as first protective pipe, second protective pipe, etc., and the clamp mounting seats are referred to as first mounting seats, second mounting seats, etc.) First, the two first mounting seats are installed on the inner bottom wall of the installation pit. Then, the first protective pipe is passed through the inside of the clamps of the two first mounting seats, and the clamps of the first mounting seats are used to tighten the first protective pipe. Subsequently, the two second mounting seats are installed in the installation pit, located on one side of the length direction of the first protective pipe. The moving mechanism 8 and the installation mechanism 9 are moved to the installation pit, located at the position of the second mounting seats away from the first protective pipe. Then, the installation mechanism is operated. 9. Clamp the second protective tube. At this time, operate the moving box 812 to move towards the first protective tube, and simultaneously operate the installation mechanism 9 to rotate the second protective tube at a low speed. During this process, the second protective tube passes through the clamp of the second mounting seat until the threaded groove 54 of the second protective tube is threadedly connected to the threaded tube 52 of the first protective tube. Finally, operate the installation mechanism 9 to release the second protective tube and move the moving box 812 in the opposite direction until it returns to its original position. At the same time, the electric flatbed trolley 811 moves the moving mechanism 8 and the installation mechanism 9 away from the second protective tube, thereby completing the installation operation between the two protective tubes. Similarly, at the position where the installation pit is located between the electric flatbed trolley 811 and the second protective tube, install the third mounting seat, and complete the installation operation of the third protective tube according to the above steps. This process is repeated until all protective tubes are connected and installed.

[0035] The displacement assembly 82 is used to drive the moving box 812 to move. The displacement assembly 82 includes a drive rod 821, a circular gear 822, a rack 823, and a driven bevel gear 824. The drive rod 821 is rotatably mounted inside the moving box 812, and the circular gear 822 is fixedly sleeved on the drive rod 821. The rack 823 is fixed to the top of the electric flatbed 811 and meshes with the circular gear 822 to form a T-shaped structure. The rack 823 passes through the limiting through hole 10 and slides in fit. The rack 823 passes through the recess of the concave wheel 814. The outer wall of the concave wheel 814 is in rolling connection with the top of the horizontal section of the rack 823. The meshing groove of the rack 823 is opened at the top of the vertical section of the rack 823. The driven bevel gear 824 is fixedly sleeved on the drive rod 821. The rotating assembly 83 drives the driven bevel gear 824 to rotate, which in turn drives the drive rod 821 fixed to the driven bevel gear 824 and the circular gear 822 fixed to the drive rod 821 to rotate synchronously. Since the circular gear 822 meshes with the rack 823, it drives the drive rod 821 and the movable box 812 connected to the drive rod 821 to move, thereby changing the position of the movable box 812. In addition, since a limiting through hole 10 extending to the other side wall of the movable box 812 is provided through the side wall of the movable box 812, the rack 823 passes through the limiting through hole 10 and slides in engagement. The rack 823 passes through the recess of the concave wheel 814, and the outer wall of the concave wheel 814 is in rolling connection with the top of the horizontal section of the rack 823, which helps to improve the stability of the movable box 812 when it moves.

[0036] The rotating assembly 83 drives the driven bevel gear 824 to rotate. The rotating assembly 83 includes a motor 831, a worm gear 832, and a driving bevel gear 833. The motor 831 is fixed to the movable housing 812. The worm gear 832 is fixedly mounted on the output end of the motor 831 and coaxially arranged with the output end of the motor 831. The driving bevel gear 833 is fixedly sleeved on the lower end of the worm gear 832 and meshes with the driven bevel gear 824. The mounting mechanism 9 is disposed on the movable housing 812. The mounting mechanism 9 is used to clamp and rotate the protective tube to be installed. The mounting mechanism 9 includes a rotating assembly 91, an adjusting assembly 92, and an auxiliary assembly 93. The rotating assembly 91 includes a drive tube 911, a mounting shell 912, a worm gear 913, and a clamping block 914. A drive tube 911 is rotatably connected to the movable housing 812 and passes through it. A sliding through hole 14 is provided through the side wall of the mounting shell 912. The mounting shell 912 is fixed to the end of the drive tube 911 away from the movable housing 812 and is coaxially arranged with the drive tube 911. A worm gear 913 is fixedly sleeved on the drive tube 911 and meshes with the worm 832. A clamping block 914 is slidably fitted through the side wall of the mounting shell 912 and is provided with multiple clamping blocks 914, which are evenly distributed about the axis of the mounting shell 912. When the motor 831 is working, it drives the worm 832 to rotate, which in turn causes the driving bevel gear 833 fixed to the worm 832 and the driven bevel gear 824 meshing with the driving bevel gear 833 to rotate synchronously, ensuring the normal movement of the movable housing 812. First, insert the mounting shell 912 into the threaded tube 52 of the protective tube. Then, operate the adjusting component 92 to drive multiple clamping blocks 914 to move away from the axis of the mounting shell 912 until the end face of the clamping block 914 is in close contact with the inner wall of the threaded tube 52, thus achieving the clamping operation of the protective tube.

[0037] The adjusting assembly 92 is used to drive multiple clamping blocks 914 to move in a direction away from the axis of the mounting housing 912. The adjusting assembly 92 includes rollers 921, adjusting blocks 922, connecting rods 923, and sliders 924. The rollers 921 are rotatably mounted on the side wall of the clamping blocks 914 near the axis of the mounting housing 912. The adjusting blocks 922 are rotatably mounted inside the mounting housing 912 and coaxially arranged with the mounting housing 912. The connecting rods 923 are fixed to the side wall of the adjusting blocks 922 near the moving box 812 and coaxially arranged with the adjusting blocks 922. The side wall of the adjusting blocks 922 is provided with a protrusion. The protrusion has an arc surface that is rotatably connected to the rollers 921 and eccentrically arranged with the connecting rods 923. The connecting rods 923 pass through the drive tube 911 and are rotatably connected to the drive tube 911. The sliders 924 are fixed on the clamping blocks 914 and slide in engagement with the sliding through hole 14. A sliding rod 15 is fixed inside the sliding through hole 14 and slides with the slider 924. A spring 16 is fixed between the slider 924 and the inner wall of the sliding through hole 14 and extends and retracts along the movement direction of the slider 924. The number of sliding through holes 14, sliders 924, rollers 921, protrusions, arc surfaces, sliding rods 15 and springs 16 are all equal and their positions correspond one-to-one. The rotating connecting rod 923 drives the adjusting block 922 to rotate. Since the side wall of the adjusting block 922 has a protrusion with an arc surface that is eccentrically positioned and rolls with the roller 921, and the connecting rod 923 passes through the drive tube 911 and rotates with it, the roller 921, the clamping block 914 rotatedly connected to the roller 921, and the slider 924 fixed to the clamping block 914 all move away from the axis of the adjusting block 922. Simultaneously, the spring 16 is gradually stretched until the clamping block 914 is pressed tightly against the inner wall of the threaded tube 52. Similarly, rotating the connecting rod 923 in the opposite direction drives the adjusting block 922 to rotate, and the spring 16 gradually contracts and returns to its original position. This causes the roller 921, the clamping block 914 rotatedly connected to the roller 921, and the slider 924 fixed to the clamping block 914 to move closer to the axis of the adjusting block 922 and return to its original position, thus releasing the threaded tube 52 from the clamp.

[0038] The auxiliary component 93 facilitates the rotation of the connecting rod 923 and locks it with the drive tube 911 after rotation. The auxiliary component 93 includes a handwheel 931, a drive block 932, and a plug rod 933. The handwheel 931 is slidably mounted on the connecting rod 923, and the drive block 932 is fixed to the inner wall of the handwheel 931. A drive groove 11 is provided on the side wall of the connecting rod 923 for the drive block 932 to slide into, and an annular groove 12 is provided on the side wall of the connecting rod 923 to slide with the drive block 932 and communicate with the drive groove 11. The insertion rod 933 is fixed to one end of the handwheel 931 near the drive tube 911. The drive tube 911 near the handwheel 931 has a slot 13 for insertion of the insertion rod 933. There are two slots 13. The angle formed by the line connecting the center of one slot 13 and the axis of the drive tube 911 and the line connecting the center of the other slot 13 and the axis of the drive tube 911 is equal to the angle formed between the two clamping blocks 914. Pulling handwheel 931 away from drive tube 911 will cause drive block 932 and insert rod 933, both fixed to handwheel 931, to move away from drive tube 911 until drive block 932 moves from annular groove 12 into drive groove 11, and insert rod 933 separates from slot 13. Rotating handwheel 931, limited by drive groove 11 and drive block 932, will cause connecting rod 923 to rotate until insert rod 933 rotates to the position of another slot 13. At this point, clamping block 914 is flush against the inner wall of threaded tube 52. Then, pushing handwheel 931 towards drive tube 911 will insert insert rod 933 into the corresponding slot 13, reducing the probability of handwheel 931 deflecting when drive tube 911 rotates. The top of the electric flatbed 811 is fixed with two placement seats 17, each with a rounded top structure. Multiple ball bearings 18 are movably mounted on the surface of the rounded structure of each placement seat 17. A limit plate 19 is fixed on the placement seat 17 near the moving box 812. A support plate 20 is fixed to the top of the electric flatbed 811, and a drive pipe 911 passes through and engages with the side wall of the support plate 20. First, using a lifting device, both ends of the protective pipe are overlapped within the rounded structures of the two placement seats 17, and the outer wall of the protective pipe contacts the surface of the ball bearings 18. At this point, the mounting shell 912 is coaxial with the threaded pipe 52. When clamping the threaded pipe 52, simply move the moving box 812 horizontally until the mounting shell 912 moves into the threaded pipe 52, facilitating the clamping operation of the protective pipe.
