Technical Field

[0001] The utility model relates to the technical field of oil and gas storage and transportation, in particular to a flexible composite pipe damage-proof supporting device. Background Art

[0002] In the oil and gas storage and transportation industry, flexible composite pipes are generally used as oil pipelines for crude oil transportation. In order to protect the safety of the oil pipeline, it is buried underground. When the oil pipeline passes through a bridge, the casing is first fixed to the bridge, and then the oil pipeline is set inside the casing.

[0003] However, this connection method does not provide sufficient support for the flexible composite pipe. When the flexible composite pipe is affected by thermal expansion and contraction, it will stretch and shrink, causing cutting damage to the end face of the contact casing, leading to crude oil leakage and environmental pollution.

[0004] Therefore, the prior art still needs to be improved and enhanced. Summary of the invention

[0028] In this example, see Figure 1 A damage-proof support device for a flexible composite pipe 1 comprises a flexible composite pipe 1, which is fixed to the side of a bridge through a sleeve, and comprises a sleeve clamp, which is covered on the outside of the sleeve and fixed on the bridge; a plurality of concave sections are arranged on one side of the sleeve clamp, and the plurality of concave sections are hinged and fixed in pairs, and the plurality of concave sections are connected to form a receiving cavity to accommodate the flexible composite pipe 1; a plurality of elastic members 8 are connected between the plurality of concave sections, and the two ends of the elastic members 8 are respectively connected to the protruding ends of the two concave sections.

[0029] A plurality of concave sections are continuously hinged to form a flexible protection, and the flexible composite pipe 1 is protected therein, and every two concave sections are connected by an elastic member 8, so that the concave sections can fit the flexible composite pipe 1 more closely to form an effective protection, and when the flexible composite pipe 1 expands due to heat, the expansion size of the flexible composite pipe 1 can be further limited to form a multi-directional protection, and reduce the possibility of damage at the connection.

[0030] It should be noted that, in this embodiment, the pipe sleeve clip 3 consists of two parts, one half is welded with a concave section, and the other half exists separately. After the two parts are combined, the concave section of the first part can be fixed at the connection of the flexible composite pipe 1 to form preliminary pipeline protection.

[0031] Among them, an annular boss 11 is provided on one side of the pipe sleeve clamp 3, the annular boss 11 is connected to the support plate 9, and the horizontal position of the horizontal roller 10 is higher than the annular boss 11, so as to avoid the flexible composite pipe 1 from being cut and damaged due to the flexible pipe 1 contacting the annular boss 11 in the pipe sleeve clamp 3 when the flexible composite pipe 1 expands and contracts due to heat.

[0032] It should be understood that the elastic member 8 in the present application is a spring, which can form a tensioning force on the flexible composite pipe 1 to prevent the flexible composite pipe 1 from falling due to gravity when transporting crude oil, causing damage such as cutting.

[0033] Specifically, see Figure 1 In this embodiment, the concave section is composed of a support sheet 9, a shaft rod 5 and a roller 4. One end of the two support sheets 9 is connected by a horizontal roller 10 and is welded and fixed to the pipe sleeve clamp 3. Two through holes are provided on the support sheet 9 to facilitate the horizontal roller 10 to pass through and is fixed to the two support sheets 9 by nuts 6; one end of the shaft rod 5 is connected to the middle of the support sheet 9, and the other end is connected to the elastic member 8; the roller 4 is sleeved on the shaft rod 5.

[0034] During specific use, the first concave section is welded and fixed to the pipe sleeve clamp 3, and the second concave section is connected by passing through two support plates 9 on both sides of the horizontal roller 10 and fixed by nuts 6 to form a hinge, and is connected to a fixed length in turn to protect the flexible composite pipe 1 from excessive expansion.

[0035] In this example, see Figure 2 A plurality of fixing clips are provided at one end of the shaft 5 connected to the elastic member 8, and the fixing clips are connected to the elastic member 8. In the present embodiment, the fixing clips are fixed nuts 7, and a hollow is provided in the middle of the fixing nuts 7 to facilitate the installation of the spring.

[0036] Specifically, the present invention includes the following steps when implemented:

[0037] 1. Installation: Sleeve the flexible composite pipe 1 into the casing 2, and use the casing clamp 3 and bolts to fix it. The concave section is welded to the lower part of the casing clamp 3, so the lower part of the casing clamp 3 and the concave section form a whole. Then clamp the flexible composite pipe 1 into the casing and place it on the upper side of the horizontal roller 10 to keep the flexible composite pipe 1 stable.

[0038] 2. Use: In specific use, the part without the concave section at the right end of the flexible composite pipe 1 is the buried part. When the flexible composite pipe 1 contracts due to cold, the concave section bends accordingly. At this time, the spring is in a stretched state due to the contraction force of the flexible composite pipe 1. When the flexible composite pipe 1 expands due to heat, the concave section recovers accordingly, and then the spring connected between the concave sections also recovers to a contracted state.

[0039] The technical solution adopted by the utility model can effectively protect the flexible composite pipe during use, and prevent the flexible composite pipe from being affected by thermal expansion and contraction and contacting the two ends of the casing to cause cutting and damage, and has the following beneficial effects:

[0040] 1. Practical and cost-saving: It is suitable for all kinds of flexible composite pipes crossing bridges to avoid replacement of flexible composite pipes due to damage caused by cutting.

[0041] 2. Environmental protection: effectively protect the flexible composite pipe to avoid pipeline damage and crude oil leakage that pollutes the environment.

The present invention is intended to cover any variations, uses or adaptations of the present invention, which follow the general principles of the present invention and include common knowledge or customary technical means in the art that are not disclosed in the present disclosure. The specification and examples are to be regarded as exemplary only, and the true scope and spirit of the present invention are indicated by the claims.
