Description

Technical Field

[0001] This utility model relates to the field of oil and gas pipeline cleaning technology, and in particular to a sliding support structure suitable for launching and receiving tubes. Background Technology

[0002] A pig launcher / receiver is a device used to clean crude oil pipelines. It can remove condensed oil, wax, and scale from crude oil pipelines, thereby reducing the resistance of crude oil pipelines during oil transportation and lowering the oil transportation temperature.

[0003] Currently, the basic installation method of the ball receiving and launching tube has the following problems:

[0004] (1) The launcher and receiver equipment will have axial and radial displacement due to the influence of the pipeline system. Since the reserved bolt holes for fixing the saddle of the launcher and receiver are oblong holes, the launcher and receiver will be difficult to install when the radial displacement exceeds the installation displacement margin.

[0005] (2) During the design phase, the radial displacement of the launching and receiving tube is usually controlled to be about one bolt diameter to meet installation requirements. However, during the launching and receiving process, the axial and radial displacement of the launching and receiving tube is further increased due to the impact of the pig. When the axial displacement exceeds the design displacement, the anchor bolts bend, which can lead to anchor bolt breakage and foundation cracking, seriously affecting pipeline safety.

[0006] (3) When the actual axial displacement exceeds the design displacement, the force on the support is concentrated and transferred to the anchor bolts, which leads to stress concentration and increased force on the anchor bolts. The force on the anchor bolts is borne by the ball launcher and receiver foundation, resulting in a larger foundation size and increased cost. At the same time, it will also cause difficulties in surrounding piping and construction, and the location of related pipelines will be restricted. Utility Model Content

[0007] The purpose of this utility model is to provide a sliding support structure suitable for ball receiving and launching tubes, which solves the shortcomings of existing ball receiving and launching tubes, such as difficult installation, poor safety, high installation cost, and large space occupation.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] A sliding support structure suitable for a ball receiving and launching tube includes a saddle base plate located at its bottom. The horizontal cross-sectional shape of the saddle base plate is square. The sliding support structure for the ball receiving and launching tube includes a support seat and stops. The support seat is provided with a loading position for supporting the saddle base plate. Four stops are provided, which are respectively pressed against the four corners of the saddle base plate. One end of each stop is fixedly connected to the support seat. A movable allowance is provided between the stop and the saddle base plate along a first horizontal direction and a second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction.

[0010] Preferably, the vertical cross-section of the stop block is L-shaped and includes a horizontal part and a vertical part connected to each other. The horizontal part is pressed against the receiving and launching tube, and the vertical part extends downward in the vertical direction and is fixedly connected to the support base. A vertical stepped surface is provided between the horizontal part and the vertical part, and the vertical stepped surface is provided with the movable allowance space between it and the receiving and launching tube along the first horizontal direction.

[0011] Preferably, there is a horizontal stepped surface between the horizontal part and the vertical part, the horizontal stepped surface is adjacent to the vertical stepped surface, and part of the horizontal stepped surface is pressed against the receiving and launching tube, and the space below the remaining part of the horizontal stepped surface forms the movable margin space.

[0012] Preferably, the dimension a of the horizontal stepped surface along the first horizontal direction is 5-30 mm.

[0013] Preferably, the dimension b of the vertical stepped surface along the vertical direction is 20-30 mm.

[0014] Preferably, the stop block is welded to the support base.

[0015] Preferably, the support base includes a concrete layer and a steel plate, wherein a pre-embedded groove is formed on the surface of the concrete layer, and the steel plate is embedded in the pre-embedded groove.

[0016] Preferably, the top surface of the steel plate is flush with the opening edge of the pre-embedded groove.

[0017] The beneficial effects of this utility model are as follows: In this embodiment, when the launching and receiving tube experiences axial or radial displacement due to the pipeline system before assembly, the stop block can stably place the launching and receiving tube on the support base before fixing it to the support base. This avoids the need for additional pre-embedded holes for anchor bolts, reduces workload, and ensures convenient installation of the launching and receiving tube. Furthermore, even if the launching and receiving tube's axial and radial displacement further increases during subsequent use, the available space can effectively absorb the displacement without affecting the stop block's fixation of the launching and receiving tube. This ensures pipeline safety and effectively enhances the overall stability and long-term operational reliability of the launching and receiving tube. The design is simpler, the performance is more reliable, and it solves the problems of stress concentration in anchor bolts and excessive foundation bearing capacity caused by the lack of radial displacement margin when using anchor bolts to fix the launching and receiving tube.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] The technical solution provided by this utility model will be described below with reference to the accompanying drawings and specific implementation schemes.

[0030] It should be noted in advance that the foundation installation of the launcher and receiver tube is currently carried out in the following manner: (1) The unit responsible for installation pours the foundation according to the plan layout and size of the saddle base plate of the launcher and receiver tube, and reserves the pre-embedded holes for anchor bolts during the pouring process. The shape of the holes is an oblong hole; (2) After the launcher and receiver tube is hoisted into place, the pre-embedded bolts are aligned with the bolt holes, and the foundation reserved holes for the anchor bolts are grouted to the design size; (3) After the concrete strength reaches the design requirements, the anchor bolts and nuts are tightened. When tightening, the launcher and receiver tube uses two sliding saddle supports. Each anchor bolt of the sliding saddle support uses two nuts. After tightening the first nut, it is turned back one turn and the second nut is locked; (4) The saddle base plate is grounded, and the support construction is completed.

[0031] However, the above installation method has the following problems:

[0032] (1) The launcher and receiver equipment will have axial and radial displacement due to the influence of the pipeline system. Since the reserved bolt holes for fixing the saddle of the launcher and receiver are oblong holes, the launcher and receiver will be difficult to install when the radial displacement exceeds the installation displacement margin.

[0033] (2) During the design phase, the radial displacement of the launching and receiving tube is usually controlled to be about one bolt diameter to meet installation requirements. However, during the launching and receiving process, the axial and radial displacement of the launching and receiving tube is further increased due to the impact of the pig. When the axial displacement exceeds the design displacement, the anchor bolts bend, which can lead to anchor bolt breakage and foundation cracking, seriously affecting pipeline safety.

[0034] (3) When the actual axial displacement exceeds the design displacement, the force on the support is concentrated and transferred to the anchor bolts, which leads to stress concentration and increased force on the anchor bolts. The force on the anchor bolts is borne by the ball launcher and receiver foundation, resulting in a larger foundation size and increased cost. At the same time, it will also cause difficulties in surrounding piping and construction, and the location of related pipelines will be restricted.

[0035] Based on the above situation, this embodiment provides a sliding support structure suitable for launch and receiver tubes, combined with... Figures 1 to 3 As shown, the sliding support structure includes a support base 1 and stop blocks 2. The support base 1 has a loading position for supporting the saddle base plate 100 located at the bottom of the ball receiving / launching tube. The saddle base plate 100 has a square horizontal cross-sectional shape. Four stop blocks 2 are provided, each pressing against one of the four corners of the saddle base plate 100, with one end of each stop block 2 fixedly connected to the support base 1 to restrict the vertical movement of the saddle base plate 100. Additionally, in this embodiment, along the first horizontal direction (reference...) Figure 1 (as shown on the X-axis) and along the second horizontal direction (reference) Figure 1 As shown on the Y-axis, there is a movable allowance space between the stop block 2 and the saddle base plate 100.

[0036] The allowable space for movement between the stop block 2 and the saddle base plate 100 is calculated based on stress analysis. The first horizontal direction is parallel to the axial direction of the launcher / receiver tube, and the second horizontal direction is parallel to the radial direction of the launcher / receiver tube. This design ensures that if the launcher / receiver tube experiences axial or radial displacement due to the piping system before assembly, the stop block 2 can stably place the launcher / receiver tube on the support base 1 before fixing it to the support base 1. This avoids the need for additional anchor bolt pre-embedded holes, reduces workload, and ensures convenient installation of the launcher / receiver tube. In addition, with the launcher and receiver tube mounted on support 1, and if its axial and radial displacement increases further during subsequent use, the available space can effectively absorb the displacement of the launcher and receiver tube, without affecting the fixation of the launcher and receiver tube by the stop block 2. This ensures pipeline safety and effectively enhances the overall stability of the launcher and receiver tube's operation and the safety and reliability of its long-term operation. The design is simpler and the performance is more reliable, solving the problems of stress concentration in the anchor bolts and excessive bearing capacity of the foundation caused by the lack of radial displacement margin when the launcher and receiver tube is fixed with anchor bolts.

[0037] Optionally, in this embodiment, the support base 1 mainly includes a concrete layer 11 and a steel plate 12. A pre-embedded groove is formed on the surface of the concrete layer 11, and the steel plate 12 is embedded in the pre-embedded groove. The aforementioned bearing positions are provided on the steel plate 12 to support the launching and receiving tube. During manufacturing, the steel plate 12 can first be prefabricated according to the external dimensions of the launching and receiving tube, making the external dimensions of the steel plate 12 approximately equal to the external dimensions of the saddle base plate 100. Then, the steel plate 12 is installed and fixed while the foundation concrete is poured, so that the steel plate 12 is embedded in the embedded groove of the concrete layer 11 after solidification. In this embodiment, the bottom of the steel plate 12 is connected to the embedded groove by anchor bars.

[0038] With the above settings, the design strength of the support base 1 can be improved by adding steel plate 12, effectively reducing the external dimensions of the support base 1 and making the support base 1 appropriately sized. In addition, in this embodiment, the stop block 2 replaces the anchor bolt, increasing the radial movement margin of the launch and receiver tube. There is no need to thicken the support base 1 to improve its ability to withstand the concentrated stress of the anchor bolt, thereby effectively reducing the external dimensions and thickness of the support base 1, thus saving costs, while ensuring a good support effect for the launch and receiver tube.

[0039] Furthermore, in this embodiment, the top surface of the steel plate 12 is flush with the opening edge of the pre-embedded groove, which can provide better structural stability for the steel plate 12.

[0040] Optionally, in this embodiment, the stop block 2 is welded to the steel plate 12 so that the stop block 2 can be stably connected to the steel plate 12, ensuring the displacement constraint effect of the stop block 2 on the ball receiving and launching tube in the vertical direction.

[0041] Specifically, refer to Figure 3 As shown, the stop block 2 provided in this embodiment has an L-shaped vertical cross-section and includes a horizontal portion 21 and a vertical portion 22 connected together. The horizontal portion 21 is pressed onto the saddle base plate 100 of the ball receiving and launching tube, and the vertical portion 22 extends downward in the vertical direction and is fixedly connected to the steel plate 12 by welding. Furthermore, a vertical stepped surface 23 is provided between the horizontal portion 21 and the vertical portion 22, and a movable allowance is provided between the vertical stepped surface 23 and the saddle base plate 100 along the first horizontal direction. This stop block 2 has a simple structure, is easy to manufacture, and is safe and reliable. It not only achieves the limiting effect on the saddle base plate 100 in the vertical direction, but also provides movable allowance for the saddle base plate 100 to move in the first horizontal direction and the second horizontal direction.

[0042] Furthermore, a horizontal stepped surface 24 is provided between the horizontal portion 21 and the vertical portion 22. The horizontal stepped surface 24 is adjacent to the vertical stepped surface 23, and a portion of the horizontal stepped surface 24 is pressed against the receiving and launching tube. The space below the remaining portion of the horizontal stepped surface 24 forms the aforementioned movable allowance space. In this embodiment, the dimension 'a' of the horizontal stepped surface 24 along the first horizontal direction is 5-30 mm. For example, 'a' can be 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, or 30 mm. This ensures that the dimension of the horizontal stepped surface 24 is not too long, which would reduce the structural strength of the horizontal stepped surface 24 and thus affect its load-bearing capacity on the saddle base plate 100; it also ensures that the dimension of the horizontal stepped surface 24 is not too short, which would reduce the risk of detachment from the saddle base plate 100 that moves along the first horizontal direction.

[0043] For example, in this embodiment, the vertical dimension b of the vertical stepped surface 23 is 20-30 mm. For example, b can be 20 mm, 22 mm, 24 mm, 26 mm, 28 mm, or 30 mm. This setting ensures that the vertical dimension of the horizontal part 21 is not too small, thus reducing its load-bearing capacity, or too large, thus avoiding material waste and increased costs, making the vertical dimension of the horizontal part 21 more reasonable and reliable.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
