Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe processing technology, specifically to a fixing structure for a corrugated pipe coil device. Background Technology

[0002] Corrugated pipes, as a type of pipe with good flexibility, corrosion resistance, and sealing properties, are widely used in many fields. In the power and telecommunications industries, corrugated pipes are used as cable protection sleeves, providing reliable physical protection for cables, preventing external mechanical damage, chemical corrosion, and electromagnetic interference, and ensuring the stability of power and communication transmission. In industrial applications, corrugated pipes can be used to transport various fluid media, such as gases and liquids, to meet the needs of different process flows.

[0003] With the increasing demand for corrugated pipes across various industries, the production scale of corrugated pipes is also expanding. Coiling is a crucial step in the corrugated pipe production process. Coiling involves winding the produced long strips of corrugated pipe into a coil shape according to specific specifications to facilitate transportation, storage, and subsequent use. The corrugated pipe coiling device is the key equipment for this process, and its performance and stability directly affect the quality and efficiency of the corrugated pipe coils.

[0004] The existing corrugated pipe coil fixing structure traditionally uses wire to bind the corrugated pipe by hand, which is cumbersome and time-consuming. Another method relies on a simple clamp-type fixing structure. However, this method makes it difficult to separate the corrugated pipe from the clamp after it is coiled, resulting in low efficiency in removing the coiled corrugated pipe and hindering efficient processing by corrugated pipe manufacturers. Utility Model Content

[0005] The purpose of this utility model is to provide a fixing structure for a corrugated pipe coiling device, which can quickly and efficiently fix the corrugated pipe, and the separation of the coiled pipe from the clamp is also simple and efficient, which facilitates efficient processing by corrugated pipe manufacturing enterprises, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixing structure for a corrugated pipe coil device, including a winding drum, one end of which is concentrically fixed with a connecting seat; a corrugated pipe is provided on one side of the upper outer wall of the winding drum; an internal fixing mechanism for the winding drum, the fixing mechanism including a housing, the housing being installed on one side of the inside of the winding drum; an arc-shaped plate is provided below the housing; arc-shaped grooves are formed on both the front and rear sides of the arc-shaped plate; an arc-shaped slider is slidably connected inside the arc-shaped groove; multiple balls are slidably engaged on the surface of the arc-shaped slider, the balls being in contact with the inner wall of the arc-shaped groove; a support rod is fixedly connected to the surface of the arc-shaped slider away from the arc-shaped plate; the other end of the support rod is fixedly connected to the inner wall of the winding drum; the arc-shaped... A gear is provided on one side below the curved plate. The gear is connected to the curved plate by an arc-shaped rack. The arc-shaped rack is fixedly connected to the curved plate. A rotating rod is fixedly connected to the inner wall of the gear. A motor is fixedly connected to the rear end of the rotating rod. The motor is fixedly connected to the inner wall of the winding drum. The motor is connected to the box body through a connecting wire. A flexible strip is provided above the curved plate. A square frame is pressed against the upper surface of the flexible strip. Multiple first bolts are inserted into the upper surface of the square frame. The first bolts pass through the square frame and the flexible strip in sequence and are threaded to the curved plate. An air vent is provided between the curved plate and the box body. Both ends of the air vent are connected to connectors. The two connectors are respectively connected to the box body and the curved plate. A through groove is opened on one side of the upper outer wall of the winding drum.

[0007] Preferably, a plurality of metal strips are uniformly embedded on the upper surface of the flexible strip.

[0008] Preferably, the winding drum has a double-layer structure, with a plate at both ends. A sealing ring is abutted between the plate and the winding drum. Multiple second bolts are evenly inserted into the surface of the plate away from the winding drum. The second bolts pass through the plate and the sealing ring in sequence and are threadedly connected to the winding drum.

[0009] Preferably, the outer wall of the connecting wire is fitted with a U-shaped clip, and the U-shaped clip is fixedly connected to the winding drum.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the fixing structure of this corrugated pipe coil device has the following advantages over traditional technology: Through the coordination of the winding drum, connecting seat, bellows, and fixing mechanism, the winding drum is first connected to the winding shaft of the external bellows coiling device using the connecting seat. Next, the end of the bellows to be coiled is placed above the outer wall of the winding drum, near the right side of the through slot. Then, the battery and electronic control components inside the remote control box power the motor, causing the rotating rod and gear to rotate counterclockwise. During this process, the gear meshes with the arc-shaped rack, driving the entire arc-shaped plate to rotate counterclockwise. A portion of the arc-shaped plate passes through the through slot, penetrating the winding drum and reaching above the bellows. Afterward, the pneumatic control component inside the remote control box injects pressurized air into the arc-shaped plate through the air pipe. The internal air pressure of the arc-shaped plate increases, causing the flexible strip to expand and press against the outer wall of the bellows, thus fixing the bellows in place. At one end of the outer wall of the winding drum, the external corrugated pipe coiling device is then activated, causing the connecting seat and the winding drum to rotate, thus initiating the winding and coiling operation of the corrugated pipe. After the corrugated pipe is wound up, the pneumatic control component inside the housing is remotely controlled again to extract the pressurized air inside the arc plate through the air pipe. The air pressure inside the arc plate decreases, the soft strip shrinks in volume and separates from the corrugated pipe. Then, the electrical control component inside the housing is remotely controlled again to rotate the rotating rod and gear clockwise, retracting the arc plate from above the winding drum. Finally, the wound corrugated pipe is pulled off the outer wall of the winding drum, completing the corrugated pipe coiling operation. The entire process can achieve relatively quick and efficient fixation of the corrugated pipe, and the separation of the coiled pipe from the clamp is equally simple and efficient, facilitating efficient processing for corrugated pipe manufacturers.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5 This utility model provides a technical solution: a fixing structure for a corrugated pipe coil device, including a winding drum 1, with a connecting seat 2 concentrically fixed to one end of the winding drum 1, a corrugated pipe 3 provided on one side of the upper outer wall of the winding drum 1, and an internal fixing mechanism for the winding drum 1, the fixing mechanism including: a box body 4, the box body 4 installed on one side of the inner side of the winding drum 1, an arc-shaped plate 5 provided below the box body 4, arc-shaped grooves 6 opened on both the front and rear sides of the arc-shaped plate 5, an arc-shaped slider 7 slidably connected inside the arc-shaped grooves 6, a plurality of balls 9 slidably engaged on the surface of the arc-shaped slider 7, the balls 9 fitting against the inner wall of the arc-shaped grooves 6, a support rod 8 fixedly connected to the surface of the arc-shaped slider 7 away from the arc-shaped plate 5, the other end of the support rod 8 fixedly connected to the inner wall of the winding drum 1, and a gear 10 provided on one side below the arc-shaped plate 5, the gear 10 being... The arc-shaped rack 11 meshes with the arc-shaped plate 5 and is fixedly connected to the arc-shaped plate 5. A rotating rod 12 is fixedly connected to the inner wall of the gear 10, and a motor 13 is fixedly connected to the rear end of the rotating rod 12. The motor 13 is fixedly connected to the inner wall of the take-up drum 1 and is connected to the box body 4 through the connecting line 14. A flexible strip 16 is provided above the arc-shaped plate 5. A square frame 17 is pressed against the upper surface of the flexible strip 16. Multiple first bolts 18 are inserted into the upper surface of the square frame 17. The first bolts 18 pass through the square frame 17 and the flexible strip 16 in sequence and are threadedly connected to the arc-shaped plate 5. An air passage pipe 19 is provided between the arc-shaped plate 5 and the box body 4. Both ends of the air passage pipe 19 are connected to connectors 20. The two connectors 20 are respectively connected to the box body 4 and the arc-shaped plate 5. A through groove 25 is opened on one side of the upper part of the outer wall of the take-up drum 1.

[0016] In the specific implementation process, it is worth noting that the connecting seat 2 is made of high-strength metal, and its surface has undergone precision processing to ensure a tight and stable connection with the winding shaft of the external corrugated pipe coil device. During the connection process, it can be reinforced with specific positioning pins or bolts to prevent loosening or falling off during rotation. The winding drum 1 is cylindrical in shape, and its inner wall is smoothed to reduce the frictional resistance of the fixing mechanism during movement, thereby improving the smoothness and efficiency of the movement. The housing 4 is the core control and power supply component of the entire fixing structure, and it contains the battery pack and the electronic control unit. The battery assembly and other components provide power to the entire system, ensuring a stable energy supply for the operation of the motor 13 and the pneumatic control assembly. The electronic control assembly receives remote control signals and controls the start, stop, and rotation direction of the motor 13 according to the signal commands. It can also adjust the working state of the pneumatic control assembly. The pneumatic control assembly is connected to the arc plate 5 through the air pipe 19. According to the commands of the electronic control assembly, it controls the injection or extraction of pressurized air into the arc plate 5, thereby controlling the expansion and contraction of the flexible strip 16, and thus completing the fixing and separation operation of the bellows 3. The arc groove 6 and the arc slider 7... The combination of these components enables the rotation of the arc-shaped plate 5. The ball bearings 9 further reduce friction and improve rotational flexibility. The gear 10 and arc-shaped rack 11 employ a high-precision gear transmission design with an accurate transmission ratio, ensuring precise control of the arc-shaped plate 5's rotation angle and speed. The rotating rod 12 is a solid metal rod with sufficient strength and rigidity to withstand the torque transmitted by the motor 13. The motor 13 is a high-performance servo motor with fast response and high control precision, capable of accurately controlling the rotation direction and speed according to the instructions from the electronic control components. The connecting cable 14 uses a wear-resistant and interference-resistant special cable to ensure the motor... The signal transmission between 13 and box 4 is stable and reliable. The flexible strip 16 is made of rubber with good elasticity and sealing performance. Some reinforcing ribs can be set inside to improve the strength and durability of the flexible strip 16. The cooperation between the square frame 17 and the first bolt 18 allows the flexible strip 16 to be firmly fixed on the arc plate 5. The air pipe 19 is a flexible air pipe with a certain degree of extensibility, which can adapt to the rotation of the arc plate 5. The connector 20 adopts a quick connection design, which is convenient for installation and disassembly. The size of the through groove 25 is precisely designed according to the thickness and rotation range of the arc plate 5 to ensure that the arc plate 5 can smoothly pass through the through groove 25 to achieve rotation.

[0017] Furthermore, multiple metal strips 15 are uniformly embedded on the upper surface of the flexible strip 16.

[0018] In the specific implementation process, it is worth noting that the metal strip 15 can be inserted into the trough of the bellows 3 during the period when the flexible strip 16 expands and is pressed against the bellows 3, which can improve the clamping and fixing effect of the bellows 3.

[0019] Furthermore, the take-up drum 1 has a double-layer structure at the front and back. Both ends of the take-up drum 1 are provided with a plate 21. A sealing ring 22 is pressed between the plate 21 and the take-up drum 1. Multiple second bolts 23 are evenly inserted into the surface of the plate 21 away from the take-up drum 1. The second bolts 23 pass through the plate 21 and the sealing ring 22 in sequence and are threadedly connected to the take-up drum 1.

[0020] In the specific implementation process, it is worth noting that it facilitates the installation of structural components inside the winding drum 1.

[0021] Furthermore, the outer wall of the connecting line 14 is fitted with a U-shaped clip 24, which is fixedly connected to the take-up drum 1.

[0022] In the specific implementation process, it is worth noting that the U-shaped clip 24 can fix and protect the connecting wire 14, preventing the connecting wire 14 from shaking, getting tangled or worn during the rotation of the winding drum 1, ensuring stable and reliable electrical signal transmission between the motor 13 and the box 4, and improving the working stability and safety of the entire fixing structure.

[0023] Working principle: Installation and initial positioning: Before starting the corrugated pipe coiling operation, first use the connecting seat 2 to connect the winding drum 1 to the winding shaft of the external corrugated pipe coiling device to ensure that the winding drum 1 can rotate stably with the shaft of the coiling device. Then, accurately place the end of the corrugated pipe 3 to be coiled on the upper part of the outer wall of the winding drum 1 and close to the right side of the through groove 25 to prepare for the subsequent fixing operation.

[0024] Bellows fixing operation: The battery and electronic control components inside the box 4 are remotely controlled to power the motor 13. The motor 13 starts to run and drives the rotating rod 12 to rotate counterclockwise. Since the gear 10 is fixedly installed on the rotating rod 12, the gear 10 will rotate counterclockwise synchronously with the rotating rod 12. During the counterclockwise rotation of the gear 10, it meshes with the arc-shaped rack 11. The arc-shaped rack 11 is fixed on the arc-shaped plate 5. This meshing transmission causes the arc-shaped plate 5 to rotate counterclockwise as a whole. As the arc-shaped plate 5 rotates, a part of it will pass through the through groove 25 pre-set on the winding drum 1. The air passes through the winding drum 1 and reaches the corrugated pipe 3 placed on the outer wall of the winding drum 1. When the arc plate 5 reaches the appropriate position, the pneumatic control component inside the remote control box 4 starts to work, injecting pressurized air into the arc plate 5 through the air pipe 19. As the pressurized air is injected, the air pressure inside the arc plate 5 gradually increases. The soft strip 16 installed inside the arc plate 5 expands in volume under the action of air pressure. The expanded soft strip 16 is tightly pressed against the outer wall of the corrugated pipe 3, thereby firmly fixing the corrugated pipe 3 to one end of the outer wall of the winding drum 1, providing a stable fixed foundation for subsequent coiling operations.

[0025] Corrugated pipe winding operation: After the corrugated pipe 3 is fixed, the external corrugated pipe coiling device is started, so that the connecting seat 2 and the winding drum 1 start to rotate. Since one end of the corrugated pipe 3 has been firmly fixed on the winding drum 1, as the winding drum 1 rotates, the corrugated pipe 3 will be gradually wound up and coiled to form a regular tube coil.

[0026] Bellows separation operation: After the bellows 3 is wound up, the pneumatic control components inside the housing 4 are remotely controlled again to extract the pressurized air inside the arc-shaped plate 5 via the air pipe 19. As the pressurized air is extracted, the air pressure inside the arc-shaped plate 5 decreases, and the flexible strip 16 shrinks back under its own elasticity, separating from the outer wall of the bellows 3 and releasing its fixing effect on the bellows 3. Then, the electrical control components inside the housing 4 are remotely controlled again to change the rotation direction of the motor 13, causing the rotating rod 12 and gear 10 to rotate clockwise. The clockwise meshing of gear 10 with the arc-shaped rack 11 transmits power. The rotating mechanism drives the arc plate 5 to rotate clockwise, retracting it from above the winding drum 1 to create space for removing the coiled corrugated pipe 3. The coiled corrugated pipe 3 is then pulled off the outer wall of the winding drum 1, completing the entire coiling operation of the corrugated pipe 3. This fixing structure of the present invention can quickly and efficiently fix the corrugated pipe 3 throughout the entire working process. Furthermore, the separation of the coiled pipe from the clamp (i.e., the fixing component composed of the arc plate 5 and the flexible strip 16) is equally simple and efficient, greatly improving the processing efficiency of corrugated pipe manufacturing enterprises.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
