Description

Technical Field

[0001] This invention relates to the technical field of protective components for transporting plastic-coated steel pipes, and specifically to a protective device for plastic-coated steel pipes with flanges. Background Technology

[0002] During the transportation of plastic-coated steel pipes, this device can prevent the steel pipes from being damaged during handling and loading / unloading, such as scratches, collisions, or deformation. When installing plastic-coated steel pipes, this device can help fix the steel pipes, especially in places where precise positioning and flange fixing are required. At the construction site, this device can provide additional safety protection to prevent accidental injuries caused by the movement or improper installation of the steel pipes. With this device, the maintenance and inspection of plastic-coated steel pipes can be carried out more conveniently, ensuring the normal operation of the pipeline system. The main function of this protective device is to protect the integrity of plastic-coated steel pipes during transportation, installation, and use, thereby improving work efficiency and safety. Chinese Patent Publication No. CN111232428B, entitled "A Protective Device and Protective Packaging Method for Flange-Coated Steel Pipes," includes an installation plate, studs, an inner support frame, and an outer buckle frame. A threaded sleeve is fixedly connected to the center of the installation plate, and a stud is screwed onto the inner side of the threaded sleeve. This invention employs a bracket-type transport structure, allowing the coated steel pipe bracket to be installed between two sets of installation plates. This reduces contact wear on the inner surface of the coated steel pipe during hoisting and transport, thereby improving the protective performance of the transported coated steel pipe. Furthermore, the internal stacking assembly structure facilitates non-contact stacking and transport of the coated steel pipes, reducing impact and scratches on the outer surface of the coated steel pipe during stacked transport, thus further enhancing the protective performance and extending the service life of the coated steel pipe. The shortcomings of the above solution are as follows: Although the solution can protect the steel pipe, it cannot be adjusted during use, and the height and position of the device cannot be adjusted. This may lead to positioning difficulties during installation or transportation, especially in situations where space is limited or precise alignment is required. It also cannot fix the inside of the flange and cannot adapt to flanges of different sizes or shapes. Therefore, its applicability will be limited, and it cannot meet the technical problems of diverse installation needs. Summary of the Invention

[0003] The purpose of this invention is to provide a protective device for flanged plastic-coated steel pipes to solve the technical problems of existing technologies, such as the inability to adjust the device during use, the inability to adjust the height and position of the device, the potential for positioning difficulties during installation or transportation, especially in situations with limited space or requiring precise alignment, the inability to fix the inside of the flange, and the inability to adapt to flanges of different sizes or shapes. As a result, its application range is limited and it cannot meet diverse installation needs.

[0004] The technical problem to be solved by this invention can be achieved through the following technical solution: A protective device for a flanged plastic-coated steel pipe, comprising a base plate; Two sets of placement mechanisms are provided on the base plate; a connecting plate is connected to the end of the base plate, and a mounting plate is connected to the end of the connecting plate away from the base plate. A rotating motor is connected to the mounting plate, and a gear two is connected to the rotating end of the rotating motor. A gear ring is meshed with the outer circumference of the gear two, and an inner fixing mechanism is connected to the side of the gear ring away from the gear two. The mounting plate is connected to an outer fixing mechanism, which is symmetrically arranged. Each outer fixing mechanism includes two connecting ring 1 and two connecting ring 2. A limiting shell is connected between the connecting ring 1 and the connecting ring 2. The connecting ring 1 is located on one side of the mounting plate. An adjustment mechanism is connected between the mounting plate and the connecting ring 1. A pull rope is connected between the two connecting ring 1, and a winding mechanism is connected between the pull ropes.

[0005] As a further aspect of the present invention, the bottom of the base plate is connected to a plurality of casters.

[0006] As a further aspect of the present invention: each set of the placement mechanism includes an electric telescopic rod and a placement plate, wherein the electric telescopic rod is connected to the base plate and the placement plate is connected to the telescopic end of the electric telescopic rod.

[0007] As a further aspect of the present invention, the placement plate has an arc-shaped structure.

[0008] As a further aspect of the present invention: the second gear is connected to the outer periphery of the gear ring with a protective shell.

[0009] As a further aspect of the present invention: the inner fixing mechanism includes an electric telescopic rod II, and multiple electric telescopic rod IIs are provided, each of which is mounted on a toothed ring, and a stabilizing plate is connected to the end of the electric telescopic rod II away from the toothed ring.

[0010] As a further aspect of the present invention: the stabilizing plate is an arc-shaped plate.

[0011] As a further aspect of the present invention, the limiting shell is made of rubber.

[0012] As a further embodiment of the present invention: the adjustment mechanism includes two adjustment plates and two gears. The mounting plate is provided with two sets of sliding grooves. The ends of the two adjustment plates are vertically slidably connected in the sliding grooves. The adjustment plates are connected to multiple sets of teeth. Two sleeves are connected to the connecting ring. An electric motor is connected inside the sleeve. The gear is connected to the drive end of the electric motor. The gear meshes with the teeth. The adjustment plates slide laterally inside the sleeves.

[0013] As a further embodiment of the present invention: the winding mechanism includes an electric winding frame and a mounting shell, the mounting shell having a rope threading hole, a fixing plate connected to the side of the mounting shell, the electric winding frame being disposed on one side of the fixing plate, a rotating bearing being connected between the electric winding frame and the fixing plate, and a plug-in lock being connected between the electric winding frame and the fixing plate.

[0014] The beneficial effects of this invention are: 1. This invention places a flanged plastic-coated steel pipe onto the device, positioning the flange between the inner fixing mechanism and the outer placement mechanism. A rotating motor on the mounting plate drives a gear two to rotate. The outer circumference of the gear two is meshed with a toothed ring. A protective shell protects the gear two and the toothed ring. By adjustment, the stabilizing plate is rotated to a suitable position. Then, the electric telescopic rod two extends and retracts, stabilizing the inner side of the flange and protecting the steel pipe flange. The telescopic function of the electric telescopic rod one allows the placement plate to be adjusted in height, enabling placement and positioning of steel pipes of different specifications. This ensures that the steel pipe is stable and vertical on the device. During transportation, the stable placement of the steel pipe reduces damage caused by vibration or collision, improving transportation efficiency.

[0015] 2. In this invention, the outer side of the flange is placed between the limiting shells. The motor drives gear one to rotate, which in turn drives the meshing teeth to move, thus moving the adjusting plate. When the adjusting plate moves, it can move the position of the limiting shells. The position can be adjusted by moving the limiting shells, which facilitates flange installation. Connecting ring one and connecting ring two are fixed together by a pull rope and a winding mechanism. The electric winding frame rotates, which drives the pull rope to wind up, making it easy to adjust the position between the two connecting rings one. This can accommodate different flange sizes. Through precise adjustment and fixing, the stability and safety of the flange connection can be ensured, reducing leakage or damage caused by improper connection. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-5 As shown, a protective device for flanged plastic-coated steel pipes includes a base plate 1. Multiple casters 21 are connected to the bottom of the base plate 1. Two sets of placement mechanisms are provided on the base plate 1. Each set of placement mechanisms includes an electric telescopic rod 2 and a placement plate 3. The electric telescopic rod 2 is connected to the base plate 1, and the placement plate 3 is connected to the telescopic end of the electric telescopic rod 2. The placement plate 3 has an arc-shaped structure. The arc-shaped structure of the placement plate 3 can adapt to plastic-coated steel pipes of different shapes and sizes, providing multiple placement angle options. The telescopic function of the electric telescopic rod 2 allows the placement plate 3 to adjust its height, which helps to adapt to steel pipes of different lengths and ensures the steel pipe is placed stably. A connecting plate 4 is connected to one end of the base plate 1. A mounting plate 5 is connected to the end of the connecting plate 4 away from the base plate 1. A rotating motor is connected to the mounting plate 5. A gear 22 is connected to the rotating end of the rotating motor. A gear ring 23 is meshed with the outer circumference of the gear 22. A protective shell 8 is connected to the outer circumference of the gear 22 and the gear ring 23. An inner fixing mechanism is connected to the side of the gear ring 23 away from the gear 22. The inner fixing mechanism includes multiple electric telescopic rods 29, each of which is mounted on the gear ring 23. A stabilizing plate 10 is connected to the end of the electric telescopic rod 29 away from the gear ring 23. The stabilizing plate 10 is an arc-shaped plate. The inner fixing mechanism, through the cooperation of the electric telescopic rods 29 and the stabilizing plate 10, can ensure the stability of the inner side of the flange, providing effective protection for the steel pipe flange and preventing damage during movement or storage. The mounting plate 5 is connected to an outer fixing mechanism, which is symmetrically arranged. Each outer fixing mechanism includes two connecting rings 1-6 and two connecting rings 2-12. A limiting shell 11 is connected between the connecting rings 1-6 and 2-12. The limiting shell 11 is made of rubber, which has good elasticity and wear resistance, providing a stable fixing effect while reducing damage to the flange. The connecting rings 1-6 are located on one side of the mounting plate 5. An adjustment mechanism is connected between the mounting plate 5 and the connecting rings 1-6. The adjustment mechanism includes two adjusting plates 19 and two gears 20. The upper part is provided with two sets of sliding grooves 7. The ends of the two adjusting plates 19 are vertically slidably connected in the sliding grooves 7. The adjusting plates 19 are connected with multiple sets of teeth. The connecting ring 16 is connected with two sleeves 18. The sleeves 18 are connected with a motor. The gear 10 is connected to the drive end of the motor. The gear 10 meshes with the teeth. The adjusting plate 19 slides laterally in the sleeves 18. The outer fixing mechanism is symmetrically arranged, including two connecting rings 16 and two connecting rings 22. Through the cooperation of the limiting shell 11, the adjusting plate 19 and the gear 10, the position of the flange can be precisely adjusted to adapt to flanges of different sizes. A pull rope 13 is connected between the two connecting rings 6, and a winding mechanism is connected between the pull ropes 13. The winding mechanism includes an electric winding frame 14 and a mounting housing 15. The mounting housing 15 has a rope threading hole, and a fixing plate 16 is connected to the side of the mounting housing 15. The electric winding frame 14 is located on one side of the fixing plate 16, and a rotating bearing is connected between the electric winding frame 14 and the fixing plate 16. A plug-in lock 17 is connected between the electric winding frame 14 and the fixing plate 16. The connection can be easily adjusted by pulling the ropes 13 and the winding mechanism. The position between connecting ring 16 and connecting ring 212 is adapted to flanges of different sizes. The electric winding frame 14 and the fixing plate 16 are connected by the plug-in lock 17, which can prevent the electric winding frame 14 from rotating during the movement of the device and ensure the stability of the device. The automation and precise control of the device improves work efficiency, reduces the time and labor intensity of manual operation, and is suitable for batch processing and quick changeover operations. Through precise positioning and fixing, the device can ensure the safety of steel pipes during transportation and storage, reduce the risk of damage and leakage, and improve production safety.

[0021] The working principle of this invention: The bottom of the base plate 1 is connected to multiple casters 21, facilitating free movement of the device on the ground. The height of the placement plate 3 can be adjusted by extending and retracting the electric telescopic rod 2, enabling the placement and positioning of steel pipes of different heights. By placing the flanged plastic-coated steel pipe onto this device, the flange is positioned between the inner fixing mechanism and the outer placement mechanism. Through the inner fixing mechanism, the outer placement mechanism, and the gear system driven by the rotating motor, the flange can be precisely fixed to the device, ensuring its stability and safety. The rotating motor on the mounting plate 5 drives the gear 22 to rotate. The outer circumference of the gear 22 is meshed with a gear ring 23. The protective shell 8 protects the gear 22 and gear ring 23. By adjustment, the stabilizing plate 10 is rotated to a suitable position, and then extended and retracted by the electric telescopic rod 9, the stabilizing plate 10 stabilizes the inner side of the flange, forming protection for the steel pipe flange. The mounting plate 5 is connected to an outer fixing mechanism, which places the outer side of the flange... Between the limiting shells 11, the motor drives the gear 20 to rotate, which in turn moves the meshing teeth, thus moving the adjusting plate 19. The movement of the adjusting plate 19 moves the limiting shells 11, allowing for position adjustment and facilitating flange installation. Connecting ring 6 and connecting ring 12 are fixed together by a pull rope 13 and a winding mechanism. The rotation of the electric winding frame 14 drives the pull rope 13 to wind up, facilitating position adjustment between the two connecting rings 6 to accommodate different flange sizes. The insertion lock 17 between the electric winding frame 14 and the fixing plate 16 prevents the electric winding frame 14 from rotating, ensuring stability during movement. Electric control makes operation simple and intuitive, improving work efficiency and reducing manual operation time and labor intensity. Precise positioning and fixing ensure the safety of steel pipes during transportation and storage, reducing the risk of damage and leakage.
