Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning equipment, and more specifically, to a split-type body for a pipeline cleaning equipment. Background Technology

[0002] Pipelines play a vital role in transportation, especially in the transport of liquids and gases. During pipeline use, cleaning is an important part of routine maintenance. As pipelines age, impurities accumulate in the transported medium, leading to increased operating pressure, higher energy consumption, and more severe internal corrosion, thus increasing safety risks. Therefore, regular cleaning of the pipeline interior is necessary to ensure smooth pipeline transportation.

[0003] The principle of heavy-duty pipeline cleaning is to utilize the energy of the pipeline medium to propel it along the pipeline, generating cutting, scouring, vibration, and breaking effects. This breaks up the scale, which is then flushed out by the medium or adhered to the cleaning machine and carried away. Compared to conventional cleaning machines, heavy-duty cleaning machines have a greater scraping force, thoroughly cleaning various types of scale tightly adhering to the pipe wall without rolling. During the cleaning process, the cleaning machine needs to use a sealing cup to seal the medium and provide the power for forward movement. During operation, the pipe wall and the sealing cup generate significant friction, which is transmitted to the machine body through the connecting bolts. Therefore, the machine body bears both the thrust of the medium and the enormous friction from the pipe wall. Insufficient structural strength can lead to breakage at the machine body's connection points.

[0004] However, the existing heavy-duty pipeline cleaning tools are not strong enough. Especially for larger pipelines, as the pipeline diameter and pressure increase, the size and weight of the cleaning tool will also increase proportionally. The split-type body structure used in the original heavy-duty pipeline cleaning tools will not be able to withstand the load, which may lead to serious consequences such as structural breakage.

Detailed Implementation

[0026] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0027] Please refer to Figures 1-2The diagram shown is a schematic of the overall structure of the split-type pigging unit.

[0028] This embodiment provides a split-type pigging unit, including a first unit 10 and a second unit 20, which are connected by a tenon and mortise structure 30.

[0029] The following will further describe a split-type pigging unit according to this exemplary embodiment.

[0030] In some embodiments, the mortise and tenon structure 30 includes a first shaft connected to one end of the first body 10 and a second shaft connected to one end of the second body 20. The outer side of the first shaft is provided with at least a pair of opposing arc-shaped grooves 31. The second shaft includes at least a pair of opposing arc-shaped protrusions 32, which are adapted to the arc-shaped grooves 31, and the two arc-shaped protrusions 32 form a shaft hole through which the first shaft passes. The outer diameter of the first shaft is the same as the outer diameter of the second shaft. Through this structural design, during connection, the first shaft passes into the shaft hole of the second shaft, and the arc-shaped protrusions 32 are adapted to insert into the corresponding arc-shaped grooves 31 to form the mortise and tenon structure 30, thus connecting the first body 10 and the second body 20 with the mortise and tenon joint. This improves the connection strength and stress resistance of the body structure, making the body less prone to breakage and exhibiting high reliability.

[0031] In a preferred embodiment, the arc-shaped protrusion 32 includes a first protrusion 321 and a second protrusion 322. The two first protrusions 321 extend relative to each other along the axial direction of the second shaft. The second protrusion 322 is located at one end of the first protrusion 321 near the first shaft, and the two second protrusions 322 extend in the same clockwise direction along the circumference of the second shaft. The first protrusion 321 and the second protrusion are integrally connected to form an L-shaped structure similar to an arc.

[0032] The aforementioned arc-shaped groove 31 includes a first groove portion 311 and a second groove portion 312. The two first groove portions 311 extend axially relative to each other along the first shaft body and penetrate one end face of the first shaft body near the second shaft body, so that the first protrusion 321 can be fully inserted into the first groove portion 311. The first groove portion 311 is adapted to the first protrusion 321; the second groove portion 312 is located at the end of the first groove portion 311 away from the second shaft body, and the two second groove portions 312 extend in the same clockwise direction along the circumference of the first shaft body. The second groove portion 312 is adapted to the second protrusion 322; the first groove portion 311 and the second groove portion 312 are integrally formed to form an L-shaped groove structure similar to an arc.

[0033] Two opposing arc-shaped protrusions 32 are inserted into two opposing arc-shaped grooves 31, and the second protrusion 322 and the second groove 312 both extend in the same clockwise direction in the circumference of the shaft, so that the arc-shaped protrusions 32 and the arc-shaped grooves 31 can be rotated and locked.

[0034] In a preferred embodiment, the first shaft and the second shaft are connected by a locking bolt 40. The locking bolt 40 passes through the first shaft and the second shaft, which can lock the first shaft and the second shaft to prevent rotation, thereby preventing the machine body from deflecting in the pipeline.

[0035] Specifically, the first shaft body is provided with a first through hole 41 that passes through two arc-shaped grooves 31, and the second shaft body is provided with a second through hole 42 that passes through two arc-shaped protrusions 32; the locking bolt 40 passes through the first through hole 41 and the second through hole 42 to connect the first shaft body and the second shaft body, and after passing through the through hole, the other end of the locking bolt 40 is locked by a nut.

[0036] In a preferred embodiment, the second shaft further includes a connecting portion located at the end of the arc-shaped protrusion 32 away from the first shaft. The connecting portion is used to connect with the second body 20. The connecting portion can be a connecting plate, which is connected to the second body 20 by locking bolts for easy assembly and disassembly.

[0037] In a preferred embodiment, the first body 10 further includes a cleaning component 11 and a first sealing cup 12, which are coaxially connected sequentially to the end of the first shaft away from the second shaft. The cleaning component 11 is used to remove dirt from the inner wall of the pipe, and the first sealing cup 12 is used to generate forward frictional force between one end of the body and the pipe.

[0038] In a preferred embodiment, the second body 20 further includes a second sealing cup 21, which is coaxially connected to the end of the second shaft away from the first shaft. The second sealing cup 21 generates forward frictional force between the other end of the body and the pipe. The first sealing cup 12 and the second sealing cup 21 propel the body forward within the pipe, thereby cleaning the dirt from the inner wall of the pipe.

[0039] Because the first body 10 and the second body 20 of this application are connected by a mortise and tenon structure 30, the strength under stress is increased. Therefore, multiple first sealing cups 12 and second sealing cups 21 can be provided to obtain higher power. Figure 1 and Figure 2 In this embodiment of the application, two second sealing cups 21 are designed.

[0040] In a preferred embodiment, both the first sealing cup 12 and the second sealing cup 21 are connected by a mounting plate and locking bolts. The mounting plate is sleeved on the shaft and is located on both sides of the first sealing cup 12 or the second sealing cup 21, and can be fixed by inserting locking bolts.

[0041] In a preferred embodiment, the cleaning component 11 includes a sleeve fitted outside the extension shaft of the first shaft and a plurality of steel brushes circumferentially disposed outside the sleeve, enabling it to powerfully remove dirt from the pipe.

[0042] The novel split-type body of this application is suitable for large-diameter pipelines, such as... wait For large-diameter oil and gas pipelines, this pigging unit is smaller, lighter, and has a higher utilization rate compared to traditional pigging units. Compared to the applicant's first-generation heavy-duty power pigging unit with its single-bolt connection, it boasts greater strength and reliability, allowing for the installation of more sealing cups for better power. Compared to domestically produced multi-section composite pigging units using universal joint connections, the split-type unit developed in this application features a simple structure, short size, reduced susceptibility to jamming, and high reliability. It ensures both strength and maneuverability, and the addition of a locking bolt 40 in the center of the mortise and tenon structure effectively prevents deflection during operation.

[0043] During installation, the first body 10 and the second body 20 can be pre-installed with independent sealing cups. After installation, the steel brush is installed on the first body 10. Then, the mortise and tenon joints of the first body 10 and the second body 20 are fitted together and rotated to lock. Finally, the locking bolt 40 is passed through the bolt hole and tightened. The main stress on the body structure is on the mortise and tenon joints; the locking bolt 40 only serves to lock and prevent rotation. For disassembly, first loosen the locking bolt 40, then rotate the first body 10 and the second body 20 to replace the parts.
