Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for steel pipe connection, specifically to a reinforcement device for a large-diameter fiberglass pipe joint. Background Technology

[0002] Fiberglass pipe is a new type of pipe made of glass fiber and its products as reinforcing materials, unsaturated polyester resin, epoxy resin and other matrix materials, and inorganic non-metallic fillers such as quartz sand and calcium carbonate. The production process includes three forms: fixed length winding, centrifugal casting and continuous winding.

[0003] Large-diameter fiberglass pipes are widely used in petroleum, chemical, and municipal water supply and drainage fields. Their lightweight, corrosion-resistant, and high-strength characteristics make them an ideal alternative to metal pipes.

[0004] However, it still has some drawbacks. For example, the current large-diameter fiberglass pipe joints lack an effective axial locking mechanism, and the joints are prone to detachment under pipeline pressure fluctuations or vibration conditions. They mostly rely on a single sealing surface. When relying solely on flange bolt connections, the joints are prone to radial displacement under lateral forces.

[0005] To address the aforementioned issues, this application proposes a reinforcement device for large-diameter fiberglass pipe joints. Utility Model Content

[0006] The purpose of this utility model is to provide a reinforcement device for large-diameter fiberglass pipe joints, which solves the problem of insufficient fixation at large-diameter fiberglass pipe joints, resulting in radial displacement and misalignment and detachment of the joints.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a reinforcement device for a large-diameter fiberglass pipe joint, wherein the large-diameter fiberglass pipe includes a first steel pipe and a second steel pipe, the first steel pipe and the second steel pipe are inserted together, and includes a fixing component, a first connecting plate, a second connecting plate and a connecting rod; The fixing component is located at the connection joint between the first steel pipe and the second steel pipe.

[0008] As a further technical solution to the above scheme, the connecting rod is a first bolt, the screw of the first bolt passes through the first connecting hole and the second connecting hole in sequence, and is tightened and fixed with a nut.

[0009] As a further technical solution of the above solution, the fixing component includes a first arc-shaped clamping block and a second arc-shaped clamping block. One end of the first arc-shaped clamping block is hinged to one end of the second arc-shaped clamping block. The other ends of the first arc-shaped clamping block and the second arc-shaped clamping block are provided with horizontal connecting plates. After passing through the two connecting plates with a second bolt, a nut is used to tighten and fix the component.

[0010] As a further technical solution of the above scheme, a clamping plate is also fitted on the first steel pipe and the second steel pipe, and a clamping ring with a wedge-shaped cross section is provided on the side of the clamping plate facing the first connecting plate and the second connecting plate.

[0011] As a further technical solution to the above scheme, the inner walls of both the first arc-shaped clamping block and the second arc-shaped clamping block are provided with anti-slip pads.

[0012] As a further technical solution to the above scheme, the connection of the first steel pipe is provided with an inner pipe, which is inserted into the second steel pipe for connection when connecting with the second steel pipe.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0021] like Figures 1-5 As shown, a reinforcement device for a large-diameter fiberglass pipe joint is provided. The large-diameter fiberglass pipe includes a first steel pipe 1 and a second steel pipe 2, which are inserted together. The device includes a fixing component 3, a first connecting plate 4, a second connecting plate 5, and a connecting rod 6. The fixing component 3 is installed at the connection joint between the first steel pipe 1 and the second steel pipe 2. The first connecting plate 4 is fitted onto the first steel pipe 1, and has multiple first connecting holes 41 along its circumference; The second connecting plate 5 is fitted onto the second steel pipe 2, and has a plurality of second connecting holes 51 along the circumferential direction that match the first connecting hole 41; Multiple connecting rods 6 are provided horizontally, with both ends passing through the first connecting hole 41 and fixed to the corresponding second connecting hole 51.

[0022] When using this device, firstly, the first steel pipe 1 and the second steel pipe 2 are aligned and inserted together. The fixing component 3 is then fitted onto the connection joint of the first steel pipe 1 and the second steel pipe 2. The first connecting plate 4 is placed on the first steel pipe 1, and the second connecting plate 5 is placed on the second steel pipe 2. Connecting rods 6 are used to connect the first connecting plate 4 and the second connecting plate 5 together, making the connection between the first steel pipe 1 and the second steel pipe 2 more stable and increasing radial stability. Under radial pressure or fluctuations, the connecting rods 6 can prevent radial movement. Furthermore, in this design, since there are multiple first connecting holes 41 and multiple second connecting holes 51, multiple connecting rods 6 are also used for joint connection and fixation. The connecting rods 6 are symmetrically distributed during installation, balancing the force and avoiding structural fatigue caused by single-point stress concentration.

[0023] like Figure 3 As shown, in a preferred embodiment, the connecting rod 6 is a first bolt. The thread 61 of the first bolt passes through the first connecting hole 41 and the second connecting hole 51 in sequence, and is tightened and fixed using a nut 62. In this embodiment, the connecting rod 6 is selected as a first bolt. After the thread of the first bolt passes through the first connecting hole 41 and the second connecting hole 51, it is tightened and fixed using a nut 62. The bolt connection method facilitates disassembly and provides a secure connection.

[0024] like Figure 2As shown, in a preferred embodiment, a clamping plate 8 is further fitted onto the first steel pipe 1 and the second steel pipe 2. The clamping plate 8 has a wedge-shaped clamping ring 81 on the side facing the first connecting disc 4 and the second connecting disc 5. In this embodiment, the clamping plate 8 is fitted onto the first steel pipe 1 and the second steel pipe 2. During the connection process of the first steel pipe 1 and the second steel pipe 2, by tightening the first bolt, the first steel pipe 1 and the second steel pipe 2 move towards the clamping plate 8 respectively. The first steel pipe 1 contacts the clamping ring 81. Since the clamping ring has a wedge-shaped cross-section, the contact area with the first steel pipe 1 gradually increases during the contact process, increasing the friction and making the installation more secure.

[0025] like Figure 5 As shown, in a preferred embodiment, the fixing component 3 includes a first arc-shaped clamping block 31 and a second arc-shaped clamping block 32. One end of the first arc-shaped clamping block 31 is hinged to one end of the second arc-shaped clamping block 32. The other ends of the first arc-shaped clamping block 31 and the second arc-shaped clamping block 32 are each provided with a horizontal connecting plate 33. After passing through the two connecting plates 33 with a second bolt 34, the connection is tightened with a nut 62. In this embodiment, the fixing component 3 adopts a clamp connection method. The first arc-shaped clamping block 31 and the second arc-shaped clamping block 32 are used to clamp the pipe. First, the openings of the first arc-shaped clamping component 31 and the second arc-shaped clamping component 32 are opened to clamp the pipe. After the pipe is pressed against the inner wall of the first arc-shaped clamping block 31 and the second arc-shaped clamping block 32, the two connecting plates 33 are aligned. The second bolt 34 is then passed through the connecting plates 33 for fixing, completing the fixing operation.

[0026] like Figure 5 As shown, in a preferred embodiment, the inner walls of both the first arc-shaped clamping block 31 and the second arc-shaped clamping block 32 are provided with anti-slip pads 7. In this embodiment, anti-slip pads 7 are added to the inner walls of the first arc-shaped clamping block 31 and the second arc-shaped clamping block 32. The anti-slip pads 7 can increase friction to prevent slippage, and the anti-slip pads 7 are made of a high coefficient of friction material to enhance the stability of clamping and prevent loosening caused by long-term vibration.

[0027] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the connection of the first steel pipe 1 is provided with an inner tube 11, which is inserted into the second steel pipe 2 for connection. In this embodiment, the inner tube 11 of the first steel pipe 1 is inserted into the inner cavity of the second steel pipe 2, forming a nested structure with the joint of the first steel pipe 1, which enhances the sealing and pressure resistance of the joint and disperses the fluid pressure impact.

[0028] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.
