Description

Technical Field

[0001] The utility model relates to the technical field of railing repair, in particular to a railing quick connection structure. Background Art

[0002] Offshore oil platform production equipment is a complex steel engineering structure, and its part above the water surface carries key equipment for oil and gas recovery and processing. On such platforms that require personnel on duty, the installation of protective railings is crucial to ensure the safety of inspection and operation personnel, especially in high-altitude operation areas. However, the high-salt and high-humidity conditions unique to the marine environment pose a severe challenge to metal structures and accelerate the corrosion process of offshore oil equipment including railings. Although the surface of the railings is coated with anti-corrosion paint, it is common for the railings to rust, break, or form gaps due to the limitations of construction technology and daily maintenance.

[0003] In the face of railing corrosion, traditional treatment methods have significant deficiencies in safety and efficiency. In safe areas, welding operations can still be used for repair, but in areas of continuous production, due to strict explosion-proof grade requirements, open flame operations are strictly restricted, resulting in only temporary measures, such as using scaffolding pipes to reinforce the corroded area, and waiting for the platform to be shut down for overhaul before welding repairs. The disadvantages of this approach are obvious: 1. High-salt and high-humidity environments will accelerate the spread of untreated corrosion points, and small corrosion points may quickly develop into large-scale corrosion that affects the use of the entire section of railings. 2. The scaffolding reinforcement method relies on other railings, which invisibly increases the load-bearing pressure of these railings and may cause chain safety hazards. 3. When human resources are tight, the construction and fixing of scaffolding may be delayed due to the lack of professional scaffolders, and it is impossible to respond to emergencies in time. 4. The internal corrosion of the railing is difficult to detect from the outside, and rainwater penetration may aggravate the internal corrosion until the railing breaks, which seriously threatens the safety of personnel. 5. Welding repairs require the cooperation of professionals and subsequent anti-corrosion painting. The entire process is time-consuming, labor-intensive, and there is a risk of re-corrosion.

As Figures 1-5 shown, according to the implementation mode of the present invention, a quick connection structure for a rail includes: a sleeve support rod 1 and a fixed clamping sleeve 6; the length of the sleeve support rod 1 is adjustable;

[0039] One ends of the two sleeve support rods 1 are respectively sleeved and connected to the connection ends of a section of the rail 8 to be connected, and the other ends of the two sleeve support rods 1 are connected through the fixed clamping sleeve 6.

[0040] In this embodiment, the core of the rapid railing connection structure lies in its flexible and stable connection method. This structure includes two telescopically adjustable sleeve support rods 1. One end of each of these two sleeve support rods 1 is tightly sleeved with the connection end of the railing 8 to be connected, ensuring a stable connection between the railing and the support rod. The other ends of the two sleeve support rods 1 are connected to each other through a special fixed clamping sleeve 6. With its unique structural design, the fixed clamping sleeve 6 can firmly hold the ends of the two sleeve support rods 1, forming a stable overall structure.

[0041] The utility model solves the problem that it is difficult to weld and repair the railing after corrosion in high-safety explosion-proof requirement places such as oil and gas production devices; it not only realizes rapid repair in a non-thermal environment, but also significantly improves the repair efficiency and reduces the labor cost; the structure of the utility model is simple, the operation is convenient, and the connection is firm, providing an efficient solution for the rapid and safe repair of the railing.

[0042] According to an embodiment of the utility model, the sleeve support rod 1 includes: a sleeve base 11, a first sleeve rod 12, and a second sleeve rod 13 that are connected in sequence;

[0043] The sleeve base 11 is sleeved and connected with the railing 8 to be connected;

[0044] The outer wall of the first sleeve rod 12 is provided with an external thread, and the inner wall of the sleeve base 11 is provided with an internal thread that matches the external thread on the outer wall of the first sleeve rod 12;

[0045] The second sleeve rod 13 is connected to the fixed clamping sleeve 6.

[0046] Preferably, a locking nut 2 is provided on the first sleeve rod 12, and the sleeved length between the sleeve base 11 and the first sleeve rod 12 is adjusted by rotating the locking nut 2.

[0047] Preferably, the railing connection structure further includes: a locking gasket 3; in the connected state, the locking gasket 3 is fixed between the locking nut 2 and the fixed clamping sleeve 6.

[0048] In this embodiment, the sleeve support rod 1 is successively connected by a sleeve base 11, a first sleeve rod 12 and a second sleeve rod 13, forming a flexible adjustable support structure. The sleeve base 11 is directly sleeved with the railing 8 to be connected, ensuring the stability of the connection. The outer wall of the first sleeve rod 12 is provided with external threads, which match the internal threads on the inner wall of the sleeve base 11. By rotating, a tight connection between the two can be achieved. This threaded connection method is not only stable but also convenient for adjusting the length to adapt to different situations. The second sleeve rod 13 is responsible for connecting with the fixed clamping sleeve 6 to firmly connect the two sleeve support rods 1 together. In addition, a locking nut 2 is provided on the first sleeve rod 12. By rotating the locking nut 2, the sleeved length between the sleeve base 11 and the first sleeve rod 12 can be further adjusted to ensure the accuracy and stability of the connection. In the connected state, a locking gasket 3 can also be added and fixed between the locking nut 2 and the fixed clamping sleeve 6 to further enhance the tightness and stability of the connection. The surface of the locking gasket 3 is relatively smooth, which can reduce the friction between the locking nut 2 and the fixed clamping sleeve 6.

[0049] Through the modular design of the sleeve support rod and the comprehensive application of threaded connection, locking nut and locking gasket, the present utility model realizes the flexible adjustment and high stability of the railing connection structure. This structure not only simplifies the installation process, improves the accuracy and stability of the connection, but also effectively reduces the friction between the connection components through the locking gasket, extends the service life, and significantly improves the technical effect and practicability of the railing connection.

[0050] According to an embodiment of the present utility model, a second rubber pad 5 is provided at the connection between the sleeve support rod 1 and the railing 8 to be connected; the second rubber pad 5 is used to prevent water vapor from entering the interior of the railing 8 from the connection.

[0051] In this embodiment, a second rubber pad 5 is provided at the connection between the sleeve support rod 1 and the railing 8 to be connected. In the connected state, the second rubber pad 5 is sleeved outside the railing 8 or abuts against the railing 8, and the size of the second rubber pad 5 matches the size of the railing 8; the sleeve support rod 1 can prevent water vapor from entering the interior of the railing 8 from the connection, reducing the risk of corrosion inside the railing.

[0052] The present utility model adds a second rubber pad at the connection between the sleeve support rod and the railing, effectively blocking the water vapor penetration path, significantly reducing the corrosion risk inside the railing caused by water vapor intrusion, thereby extending the service life of the railing and improving the durability and safety of the overall structure.

[0053] According to an embodiment of the present utility model, a first rubber pad 4 is provided inside the fixed clamping sleeve 6; in the connected state, the first rubber pad 4 wraps around the end of the sleeve support rod 1, and the fixed clamping sleeve 6 is tightly connected with the first rubber pad 4.

[0054] Preferably, the fixed clamping sleeve 6 includes a first member 61 and a second member 62 which combine to form a cylinder; the first member 61 and the second member 62 are connected by a hinge 7.

[0055] Preferably, the first member 61 and the second member 62 are fixed by a pin passing through the hinge 7.

[0056] In this real-time mode, the efficient connection of the sleeve support rod 1 is achieved through the fixed clamping sleeve 6. The fixed clamping sleeve 6 is composed of a first member 61 and a second member 62. These two members are independent of each other before combination, but are closely connected by the hinge 7, enabling them to rotate flexibly around the axis of the hinge 7. When it is necessary to connect the sleeve support rod 1, first, the first rubber pad 4 is sleeved on the end of the sleeve support rod 1 to ensure it is tightly covered. Subsequently, the first member 61 and the second member 62 are combined around both sides of the sleeve support rod 1 until they are completely closed, forming a cylindrical surrounding structure. At this time, the first rubber pad 4 is tightly compressed between the sleeve support rod 1 and the fixed clamping sleeve 6, providing additional sealing and buffering effects. Finally, the first member 61 and the second member 62 are firmly fixed together by a pin passing through the reserved hole of the hinge 7 to complete the entire connection process.

[0057] The utility model realizes the rapid, stable and sealed connection between the sleeve support rods through the fixed clamping sleeve and the first rubber pad inside it; without complex thermal operations such as welding, the installation can be completed only through simple rotation and fixation, greatly reducing the construction difficulty and cost. The first rubber pad of the utility model effectively prevents external factors such as water vapor from invading the connection, protects the internal structure of the railing, and reduces the corrosion risk; the split design of the fixed clamping sleeve combined with the hinge connection not only facilitates installation and disassembly, but also improves the flexibility and adaptability of the connection, providing great convenience for the repair and maintenance of the railing. The utility model shows remarkable technical effects in aspects such as improving construction efficiency, reducing costs, ensuring safety and extending service life.

[0058] According to an embodiment of the utility model, both the sleeve support rod 1 and the fixed clamping sleeve 6 are made of stainless steel.

[0059] In this embodiment, components such as the sleeve support rod 1, the fixed clamping sleeve 6, and the locking gasket 3 are all made of stainless steel materials, which can effectively slow down the corrosion rate of the replaced components and reduce the later maintenance cost.

[0060] The utility model makes the sleeve support rod and the fixed clamping sleeve made of stainless steel. While enhancing the structural strength, it significantly slows down the corrosion rate of the components and effectively reduces the cost of later maintenance.

[0061] The utility model combines the convenience of casing and threaded connection. Without complex hot work operations such as welding, the repair work of corroded railings can be quickly achieved, which not only ensures the integrity and safety of the railings, but also provides a safer working environment for operators, achieving significant savings in labor costs.

[0062] Embodiment 2

[0063] As Figures 1-5 shown, according to an embodiment of the present utility model, a rapid connection structure for railings is applicable to the rapid connection and repair of corroded and broken metal railings. Without hot work operations such as welding, the repair of corroded railings can be easily and quickly achieved through the connection of a casing and a thread, effectively ensuring the integrity of the railings, guaranteeing the safety of operators during operation, and saving a large amount of labor costs. The rapid connection structure for railings includes components such as a second rubber pad 5, a first rubber pad 4, a casing support rod 1, a locking nut 2, a locking gasket 3, a hinge 7, and a fixed clamping casing 6.

[0064] The second rubber pad 5 is placed between the two casings of the casing support rod 1, which can effectively prevent water vapor from entering the inside of the railing 8. The first rubber pad 4 is wrapped around the head of the casing support rod 1 and used in cooperation with the fixed clamping casing 6, which can also prevent water vapor from entering the inside of the railing 8 and corroding the railing 8.

[0065] The casing support rod 1, the locking nut 2, the locking gasket 3, the fixed clamping casing 6, etc. are all made of stainless steel materials, which can effectively slow down the corrosion rate of the components after replacement and reduce the later maintenance cost.

[0066] The casing support rod 1 is divided into three parts: the first part is the casing base 11, the middle thickness of the casing base 11 is the thickness of the railing 8, which can tightly sleeve the railing 8 between the two casing bases 11 to play a supporting role; the second part is the first sleeve rod 12 with threads, and the length of the casing support rod 1 can be adjusted by adjusting the socketing length between the first sleeve rod 12 and the casing base 11; the third part is the second sleeve rod 13, and the second sleeve rod 13 is a sleeve rod without threads; the casing base 11 and the first sleeve rod 12 are used in cooperation to adjust the position of the fixed clamping casing 6 to make the railing 8 fixed more tightly.

[0067] The locking nut 2 can rotate on the threaded sleeve rod section (the first sleeve rod 12) of the casing support rod 1 for fixed connection with the fixed clamping casing 6. The surface of the locking gasket 3 is relatively smooth, which can prevent friction between the locking nut 2 and the fixed clamping casing 6.

[0068] The fixed locking casing 6 is composed of upper and lower parts. The two parts are combined to form a cylindrical thin-walled tube, and the middle of the upper and lower parts is connected by a hinge 7, which can clamp the two casing support rods 1 to achieve the purpose of quickly connecting the railings.

[0069] The utility model realizes the rapid and welding-free repair after the metal railing rusts and breaks. Through the threaded connection of the stainless steel sleeve support rod and the fixed clamping sleeve, combined with the waterproof design of the rubber pad, it effectively prevents water vapor erosion, ensures the stable connection of the railing, safeguards the operation safety, and reduces the maintenance cost and labor input.

[0070] Working principle:

[0071] The sleeve support rod 1, the locking nut 2, the locking gasket 3, and the fixed clamping sleeve 6 are all made of stainless steel materials and have strong corrosion resistance. Place the first rubber pad 4 between the two sleeves of the sleeve support rod 1, and then insert the railing 8 between the two sleeves of the sleeve support rod 1 (the connecting end of the railing 8 is inserted into the inside of the sleeve base 11) until it reaches the bottom. Then screw the locking nut 2 to the bottom end closest to the sleeve base 11, and slip the locking gasket 3 onto the other end of the sleeve support rod 1 (outside the second sleeve 13). Repeat the above description for the cooperation between the other end of the railing 8 and the sleeve support rod 1. Slip the first rubber pad 4 onto the two sleeve support rods 1. Then open the hinge 7 at one end of the fixed clamping sleeve 6, align one end with the first rubber pad 4, close the fixed clamping sleeve 6, and then fix it with a pin passing through the hinge 7. Then rotate the locking nut 2 in the direction away from the sleeve base 11, and the two locking nuts 2 rotate towards each other at the same time. Stop rotating when a certain force is applied to the two locking nuts 2.

[0072] Due to the functions of the first rubber pad 4 and the second rubber pad 5, rainwater cannot enter the inside of the railing 8. At the same time, the cooperation between the sleeve support rod 1 and the railing 8, and the locking nut 2 and the fixed clamping sleeve 6 enables this rapid connection structure of the railing to have a certain load-bearing strength and meet the on-site use requirements.
