Description

Technical Field

[0001] The utility model belongs to the technical field of sand boxes for fixing blowout prevention pipelines, and particularly relates to a detachable sand box for fixing blowout prevention pipelines. Background Technique

[0002] Blowout prevention pipelines play an important role in drilling operations. Blowout prevention pipelines are generally high-pressure pipelines. During blowout, the instantaneous impact force is relatively large, especially on pipe fittings such as elbows, tees, and three-way joints that change the flow direction. Reasonable fixation of the pipeline can reduce the impact of this local impact force on the operation of the overall blowout prevention pipeline.

[0003] Due to the relatively high pressure during the operation of the blowout prevention pipeline, adding a certain amount of counterweight load can make the pipeline fixation more reliable. Currently, fixed sand boxes can be used to fix blowout prevention pipelines. The design and application of fixed sand boxes are to ensure the stable operation of the pipeline in harsh environments. Conventional sand boxes need to be designed in advance, and the sand boxes need to be in place during the pipeline installation stage. If the fixation effect is not ideal later, if additional sand box fixation points for the pipeline are required, the blowout prevention pipeline needs to be cut to add sand box fixation points. Content of the Utility Model

A dividing surface is formed in the middle of the box body to divide the box body into two 1 / 2 box bodies with opposite openings. An installation hole penetrating the box body is provided on the box body. The diameter of the installation hole is the same as the diameter of the blowout prevention pipe to be fixed. The central axis of the installation hole is located on the dividing surface, so that the installation hole occupies 1 / 2 on each of the two 1 / 2 box bodies. A sand filling port communicating with the inside and outside of the box body is provided at the top of the box body.

[0021] Please refer to Figure 1-2 , the present utility model provides a technical solution: a detachable sand box for fixing a blowout prevention pipeline, including a box body 1 with a hollow interior. A dividing surface 11 is formed in the middle of the box body 1 to divide the box body 1 into two 1 / 2 box bodies 2 with opposite openings. An installation hole 3 penetrating the box body 1 is opened on the box body 1. The diameter of the installation hole 3 is the same as the diameter of the blowout prevention pipe to be fixed. The central axis of the installation hole 3 is located on the dividing surface 11 so that the installation hole 3 occupies 1 / 2 on each of the two 1 / 2 box bodies 2. A sand filling port 4 communicating the inside and outside of the box body 1 is opened at the top of the box body 1. Fixing components for fixing the two 1 / 2 box bodies 2 when they are closed to form the box body 1 are respectively arranged on the two 1 / 2 box bodies 2.

[0022] In use, an installation hole 3 is opened according to the diameter of the blowout preventer pipe. After aligning the installation holes 3 on the two 1 / 2 boxes 2 with the blowout preventer pipe, the two 1 / 2 boxes 2 are moved towards each other and closed to form the box body 1, and the blowout preventer pipe is installed in the installation hole 3. The two 1 / 2 boxes 2 are fixed by the fixing component, and then the box body 1 is filled with sand through the sand filling port 4 for counterweight, so that the sand box is fixedly connected to the blowout preventer pipe. The utility model is convenient for disassembly and assembly, and is convenient for temporarily adding fixing points on the blowout preventer pipe, realizing the rapid installation and fixation of the sand box without affecting normal production and without cutting the pipeline, increasing the reliability of the stable operation of the pipeline, and ensuring safe and continuous production.

[0023] Specifically, the fixing component includes connecting ear plates 51 and bolt and nut fasteners 52. There are two groups of connecting ear plates 51, and the two groups of connecting ear plates 51 are respectively arranged around the dividing surface 11 of the two 1 / 2 boxes 2 in parallel. A number of connecting holes 53 penetrating the two are provided on the two groups of connecting ear plates 51, and the bolt and nut fasteners 52 are connected in the connecting holes 53. In use, the two 1 / 2 boxes 2 are moved towards each other and closed to form the box body 1, and the connecting ear plates 51 around the two 1 / 2 boxes 2 are aligned with each other. The bolt and nut fasteners 52 pass through the connecting holes 53 on the two groups of connecting ear plates 51 and are tightened, so as to realize the fixed connection of the two 1 / 2 boxes 2.

[0024] Specifically, the box body 1 includes a top plate 12, a cylindrical barrel 13 and a bottom plate 14. The cylindrical barrel 13 is vertically arranged and penetrates up and down. The top plate 12 and the bottom plate 14 are respectively covered on the upper and lower ends of the cylindrical barrel 13 to form a box body 1 with a hollow interior. The dividing surface 11 vertically divides the top plate 12, the cylindrical barrel 13 and the bottom plate 14 into two 1 / 2 top plates 121, two 1 / 2 cylindrical barrels 131 and two 1 / 2 bottom plates 141 respectively. The installation hole 3 horizontally penetrates the cylindrical barrel 13 and the installation hole 3 occupies 1 / 2 in each of the two 1 / 2 cylindrical barrels 131. The sand filling port 4 is opened on the top plate 12.

[0025] Furthermore, the area of the top plate 12 is larger than the cross-sectional area of the cylindrical barrel 13, and additional weights such as stones can be added on the top plate 12 when needed to enhance the overall firmness of the sand box for fixing the blowout preventer pipe.

[0026] Furthermore, the area of the bottom plate 14 is larger than the cross-sectional area of the cylindrical barrel 13, and a number of fixing holes 15 penetrating the bottom plate 14 up and down are opened in the part of the bottom plate 14 outside the cylindrical barrel 13. Thus, expansion bolts can be used to pass through the fixing holes 15 to connect the bottom plate 14 to the building structure, making the fixation of the sand box better.

[0027] Further, each set of connecting lugs 51 has two pieces, which are respectively connected to the left and right sides of the dividing surface 11 of a 1 / 2 cylindrical barrel 131, so as to connect the box body 1 on the left and right sides thereof, avoiding that the connecting lugs 51 are arranged on the upper and lower sides of the box body 1, resulting in the inability to place additional counterweights on the top plate 12 and the bottom plate 14 not being able to fit on the surface of the building structure.

[0028] Further, there are two sand filling ports 4, which are respectively opened on two 1 / 2 top plates 121, so as to fill sand into the box body 1 from both sides, improving the sand filling efficiency and avoiding the accumulation of sand and gravel on one side.

[0029] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation.
