Description

Technical Field

[0001] The present application relates to the technical field of oil pipeline installation, and specifically discloses an oil pipeline support. Background Art

[0002] Oil pipelines are pipes used to complete oil loading and unloading and transfer tasks. They are usually made of steel and have high structural strength. For oil pipelines installed on the surface, brackets are usually required to support them in order to support, fix and protect the oil pipelines.

[0003] In the existing oil pipeline support, the support includes a base, a lower hinge and an upper hinge, wherein the base is mainly fixed to the ground, and supports the lower hinge, the upper hinge and the oil pipeline as a whole, and is usually a cast concrete or steel structure column; and the lower hinge and the upper hinge enclose a cavity adapted to the oil pipeline, and the purpose of fixing the oil pipeline can be achieved by fixing the lower hinge and the upper hinge to each other, and the existing lower hinge and the upper hinge are usually tightened with bolts, and the oil pipeline used for oil transmission tasks is usually laid outdoors, resulting in the bolts used to fix the lower hinge and the upper hinge being easily affected by the external environment, causing corrosion or aging of the bolt surface, so that it is not convenient to disassemble the bolts during the maintenance of the oil pipeline support and the oil pipeline, which increases the difficulty and cost of maintenance. Therefore, in view of this, the inventor provides an oil pipeline support to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem that the surfaces of bolts used for fixing the lower hinge and the upper hinge in the traditional petroleum pipeline support are easily corroded or aged, which increases the difficulty and cost of maintenance.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a petroleum pipeline support, comprising:

[0006] Pedestal;

[0007] The upper hinge and the lower hinge are closed to form a fixed aperture adapted to the oil pipeline, the upper hinge end is symmetrically provided with a top plate, and the lower hinge end is symmetrically provided with a bottom plate;

[0008] A guide column is fixedly connected to the top plate, and the bottom of the guide column passes through the bottom plate and is fixedly connected to a connecting plate, a sleeve is provided on the connecting plate, and a first sealing ring is provided at one end of the sleeve away from the connecting plate;

[0009] A fixing stud penetrates the sleeve and is threadedly connected to the sleeve, the fixing stud is slidably connected to the connecting plate, and the fixing stud abuts against the bottom plate.

[0010] The principles and effects of this basic solution are:

[0011] Compared with the prior art, the utility model achieves the purpose of fixing the top plate and the bottom plate to each other by setting a guide column and a connecting plate, and then connecting the connecting plate and the bottom plate to each other by means of a fixing stud, and seals and protects the threaded portion of the fixing stud by means of a sleeve and a first sealing ring, thereby preventing rainwater from the external environment from directly corroding the threaded portion of the fixing stud, thereby reducing corrosion and aging of the fixing stud, and the top column can also shield rainwater, further reducing corrosion of the fixing stud by rainwater, and solving the problem that the surface of the bolts used to fix the lower hinge and the upper hinge in the traditional oil pipeline support is easily corroded or aged, which increases the difficulty and cost of maintenance.

[0012] Furthermore, the sleeve is arranged on the upper surface of the connecting plate, and the fixing stud comprises a first smooth section slidably connected to the connecting plate, an external thread section threadedly connected to the inner wall of the sleeve, and a second smooth section that can abut against the bottom plate. This arrangement can further improve the sealing between the fixing stud and the connecting plate and between the fixing stud and the sleeve, thereby providing better protection for the external thread section of the sleeve.

[0013] Furthermore, the diameter of the fixing stud is reduced in sequence from the first smooth section, the external thread section and the second smooth section, and the second smooth section is connected to the first sealing ring at the top of the sleeve in a sliding and sealing manner. This arrangement facilitates the assembly of the fixing stud.

[0014] Furthermore, the connecting plate is provided with a through hole, and the first smooth end side wall of the fixing stud is provided with a second sealing ring which is slidably and sealingly connected to the through hole. The second sealing ring can improve the sealing between the fixing stud and the connecting plate.

[0015] Furthermore, the through hole is stepped, and the diameter of the top of the through hole is smaller than the diameter of the bottom of the through hole. The stepped through hole can better match the first smooth section and the external thread section of the fixing stud.

[0016] Furthermore, a groove adapted to the end of the fixing stud is provided at the bottom of the base plate, and the end of the fixing stud abuts against the inner bottom surface of the groove. The groove can play a role in positioning the fixing thread.

[0017] Furthermore, an elastic pad is provided at the end of the fixing stud near one side of the groove. The elastic pad can protect the fixing stud and the inner bottom surface of the groove and increase the friction between the fixing stud and the inner wall of the groove.

[0026] The upper hinge 3 and the lower hinge 2: the lower hinge 2 is completely fixed to the base 1. When the base 1 is a concrete base 1, the lower hinge 2 is fixed to the base 1 by rivets. When the base 1 is a steel base 1, the lower hinge 2 is completely fixed to the base 1 by bolts or welding. The upper hinge 3 and the lower hinge 2 are both semicircular. The upper hinge 3 and the lower hinge 2 are closed to form a fixed gap adapted to the oil pipeline. The ends of the upper hinge 3 are symmetrically provided with top plates 5, and the ends of the lower hinge 2 are symmetrically provided with bottom plates 4.

[0027] Guide column 6: Figure 2As shown, the guide column 6 is fixedly connected to the top plate 5 and the bottom of the guide column 6 passes through the bottom plate 4 and is fixedly connected to the connecting plate 7. The bottom plate 4 is provided with a central hole for accommodating the guide column 6 to pass through. The top of the guide column 6 is fixed to the top plate 5 by bolts or welding. During the assembly process of the guide column 6, the oil pipeline is first placed on the lower hinge 2, and the guide column 6 passes through the bottom plate 4. Then, the guide column 6 and the connecting plate 7 are fixed by bolts or welding. The upper surface of the connecting plate 7 is provided with a sleeve 9 by welding or bolting.

[0028] Fixing stud 8: Figure 3 As shown, the fixing stud 8 passes through the sleeve 9 and is threadedly connected with the sleeve 9, the fixing stud 8 is slidably connected with the connecting plate 7, and the fixing stud 8 abuts against the bottom plate 4. Specifically, the fixing stud 8 includes a stud head 801 that is easy to rotate, a first smooth section 802 that is slidably connected with the connecting plate 7, an external thread section 803 that is threadedly connected with the inner wall of the sleeve 9, and a second smooth section 804 that can abut against the bottom plate 4, and the diameter of the fixing stud 8 is reduced in sequence from the first smooth section 802, the external thread section 803, and the second smooth section 804, and a stepped through hole is set on the connecting plate 7, and the diameter of the top of the through hole is larger than the fixing stud. The external thread section 803 of 8 is smaller than the first smooth section 802 of the fixing stud 8, the diameter of the bottom of the through hole is matched with the first smooth section 802 of the fixing stud 8, an internal thread is provided in the sleeve 9, the internal thread is matched with the external thread section 803 of the fixing stud 8, an opening is provided at the top of the sleeve 9 to match the second smooth section 804 of the fixing stud 8, a sealing groove is provided in the opening and a first sealing ring 10 is provided, a sealing groove is also provided on the outer wall of the first smooth section 802 of the fixing stud 8 and a second sealing ring is provided, a groove is provided at the bottom of the base plate 4 to match the end of the fixing stud 8, and an elastic pad is provided at the top end of the fixing stud 8.

[0029] The implementation process of this embodiment is as follows:

[0030] The first step is to install the base 1 on the installation path of the oil pipeline, and fix the lower hinge 2 to the base 1 by rivets, bolts or welding;

[0031] In the second step, the oil pipeline to be installed is placed on the lower hinge 2 by means of a crane or other equipment, and the upper hinge 3 is covered above the oil pipeline, so that the guide column 6 passes through the bottom plate 4, and then the connecting plate 7 is fixed to the guide column 6 by welding or bolting;

[0032] The third step is to pass the fixing stud 8 through the connecting plate 7 and the sleeve 9 from bottom to top. When the fixing stud 8 is not completely in contact with the groove at the bottom of the bottom plate 4, the fixing stud 8 continues to move upward, and the positions of the top plate 5 and the connecting plate 7 hardly change. When the fixing stud 8 is completely in contact with the groove at the bottom of the bottom plate 4, the fixing stud 8 can no longer move upward, resulting in the sleeve 9, the connecting plate 7 and the top plate 5 moving downward during the rotation of the fixing stud 8, that is, the top plate 5 assembly approaches the bottom plate 4, and the upper hinge 3 gradually approaches the lower hinge 2, thereby completely fixing the oil pipeline.

[0033] During the inspection and maintenance of the oil pipeline and the oil pipeline support, it is only necessary to release the fixing of the upper hinge 3 and the lower hinge 2 to the oil pipeline. In this embodiment, it is only necessary to twist the fixing stud 8 to meet the disassembly and installation requirements during the inspection and maintenance process. In this embodiment, the threaded portion of the fixing stud 8 is sealed and protected by the sleeve 9 and the first sealing ring 10, so as to prevent rainwater from the external environment from directly corroding the threaded portion of the fixing stud 8, thereby reducing the corrosion and aging of the fixing stud 8, and the top column can also shield the rainwater, further reducing the corrosion of the fixing stud 8 by the rainwater, and solving the problem that the bolt surface used to fix the lower hinge 2 and the upper hinge 3 in the traditional oil pipeline support is easily corroded or aged, which increases the difficulty and cost of maintenance.

[0034] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
