[0002] During the long-term operation of natural gas gathering and transportation pipelines, the deposition of impurities, moisture and other chemical substances in natural gas can cause fouling and liquid accumulation on the inner wall of the pipeline. These deposits not only reduce the gas transmission efficiency of the pipeline, but also can cause the corrosion of the inner wall of the pipeline to intensify, thereby affecting the safe operation of the pipeline. In order to ensure the long-term stable operation of the natural gas pipeline, it is necessary to regularly carry out pigging operation and inhibitor pre-film treatment. In addition, regular pipeline internal detection is also an important means to ensure pipeline safety.

[0043] Embodiment 1

[0044] The embodiment provides a push ball tool for pipeline cleaning, which is used for pushing a pig or a detection device into the size head position of a launching barrel. Specifically, as shown in Figures 1-3As shown, the pipeline pigging push ball tool includes a push ball rod 1, which can be composed of a solid rod body, usually made of metal or other durable materials, with sufficient strength to withstand the pushing force generated during the pushing process. The length and diameter of the rod body can be adjusted according to actual use requirements to ensure smooth pushing operation when operating in the launching barrel. One end of the push ball rod 1 is connected to the push ball frame 3, and the other end of the push ball rod 1 (the end away from the push ball frame 3) can start the anti-slip pattern. The specific form of the anti-slip pattern is not limited, for example, it can be a grid-shaped anti-slip pattern, a pitted / convex anti-slip pattern, a longitudinal groove, or a ring-shaped groove. The anti-slip pattern can effectively increase the friction between the operator's hand and the push ball rod 1, even in wet, oily, or gloved conditions, securely holding the push ball rod 1, and avoiding operational errors caused by slipping.

[0045] The outer wall of the push ball rod 1 is sleeved with a carriage 2, which is used to keep the push ball rod 1 at a predetermined position in the launching barrel. Specifically, the push ball rod 1 is kept on the center line (or axis) of the launching barrel by the carriage 2.

[0046] Further, as shown in Figures 1-4 The carriage 2 includes a frame body 21, which can extend four pairs of ears in four different directions, as shown in Figure 4 Each pair of ears is connected to a pulley 22 through, for example, a shaft sleeve and a bolt rolling connection, i.e., the frame body 21 is installed with four pulleys 22. In this embodiment, the pulleys 22 are installed opposite to each other, and the included angle between the adjacent two pulleys 22 is 90°, i.e., the connecting line of the two oppositely arranged pulleys 22 is cross-shaped, and the outer diameter of the carriage 2 matches the inner diameter of the launching barrel, for example, each pulley 22 can be in contact with the inner diameter of the launching barrel.

[0047] With this structure, the four pulleys 22 are arranged opposite to each other and evenly distributed at 90°, so that the push ball rod 1 always stays at a predetermined position in the launching barrel, ensuring uniform stress during pushing, avoiding ball jamming or operational errors caused by the inclination of the push ball rod 1; the four pulleys 22 form a more stable support structure, keeping the push ball rod 1 stable during operation, reducing operational errors caused by shaking, and improving the smoothness and reliability of the launching.

[0048] In some other embodiments, the carriage 2 includes a frame body 21, which is installed with at least three pulleys 22. Taking the case of installing three pulleys 22 as an example, the frame body 21 can extend three pairs of ears in three different directions, each pair of ears is connected to a pulley 22 through, for example, a shaft sleeve and a bolt rolling connection, and the pulleys 22 can be evenly distributed on the frame body 21, for example, the included angle between the adjacent pulleys 22 is 120°, and the outer diameter of the carriage 2 matches the inner diameter of the launching barrel.

[0049] With the structure, the slide frame 2 is in contact with the inner wall of the ball launching cylinder through the three evenly distributed pulleys 22 on the frame body 21, so that the ball pushing rod 1 can be always kept at a predetermined position in the ball launching cylinder, avoiding deviation and ensuring the stability of the force point during the ball pushing operation, thereby improving the accuracy of the ball pushing. The pulleys 22 are in contact with the inner wall of the ball launching cylinder and roll relative to the inner wall of the ball launching cylinder, reducing the friction of the ball pushing rod 1 in the ball launching cylinder, so that the ball pushing rod 1 can move forward and backward more smoothly, improving the work efficiency and reducing the labor intensity of the operator. The pulleys 22 are evenly distributed, so that the slide frame 2 is balanced in force, avoiding the inclination or blocking phenomenon caused by single-point contact, improving the stability of the ball pushing tool and ensuring the smooth operation of the cleaning operation.

[0050] Further, as shown in Figure 3 the slide frame 2 can be rotatably connected with the ball pushing rod 1 through the bearing 4. Specifically, for example, a bearing seat can be arranged at the center position of the frame body 21 of the slide frame 2, and the bearing 4 is embedded in the bearing seat. The inner ring of the bearing 4 is fixedly connected with the ball pushing rod 1, and the outer ring is fixedly connected with the frame body 21 of the slide frame 2, so that the slide frame 2 can freely rotate relative to the ball pushing rod 1. The bearing 4 can be a deep groove ball bearing, a needle bearing, etc., and is preferably a thrust ball bearing.

[0051] With the structure, the bearing 4 provides flexible rotary connection, and the slide frame 2 can freely adjust the angle relative to the ball pushing rod 1 during the forward pushing or backward pulling of the ball pushing rod 1, avoiding the jamming phenomenon and improving the smoothness of the ball pushing operation.

[0052] Of course, the bearing 4 can also be arranged to be movable along the axis of the ball pushing rod 1, for example, a long strip-shaped guide rail or a sliding guide groove can be arranged on the ball pushing rod 1, so that the bearing 4 can not only rotate, but also move along the ball pushing rod 1, further improving the smoothness of the ball pushing operation.

[0053] Further, the midpoint of the slide frame 2 is located on the axis of the ball pushing rod 1. With the structure, the slide frame 2 is centrally installed, so that the ball pushing rod 1 can always be kept on the central axis of the ball launching cylinder, ensuring that the ball pushing rod 1 keeps a good straight motion state in the ball launching cylinder, avoiding the deviation or shaking of the ball pushing rod 1 during the forward and backward pushing, thereby ensuring the stability and smoothness of the ball pushing process and reducing the occurrence of the ball jamming phenomenon.

[0054] The pipeline pigging push ball tool provided by the embodiment can ensure that the push ball rod 1 is always in a predetermined position (for example, the push ball rod 1 is always on the center line of the ball launching cylinder) in the ball launching cylinder, so that the force point during the push ball operation is more stable and controllable, the device posture is prevented from deviating, the ball jamming phenomenon is reduced, and the smooth pipeline pigging operation is ensured, and the problem of device posture deviation caused by uneven force points of the hammer and other tools used for pushing the ball is effectively avoided. The push ball rod 1 drives the push ball frame 3 to move, and then the pig or detection device is accurately sent to the size head position of the ball launching cylinder. Compared with the traditional push ball method of using a hammer to knock, the sliding function of the slide 2 replaces the traditional impact method, so that the push ball process is more gentle, the impact damage to the device is avoided, and the problem of device and pipeline damage caused by the direct impact of the metal hammer on the pig or detection device is effectively avoided. When in use, the construction personnel can directly operate the push ball rod 1 to perform the push ball operation, so that the push ball process is more controllable, the safety accidents caused by improper operation are reduced, and the safety and reliability of the operation are improved.

[0055] The pipeline pigging push ball tool provided by the embodiment has a simple structure and is easy to carry, the push ball process is more efficient, the labor input and operation time are reduced, and the pipeline pigging push ball tool is especially suitable for large-diameter pipelines and long-distance operations.

[0056] Embodiment 2

[0057] On the basis of the embodiment 1, the specific form of the push ball frame 3 is described in the embodiment. In the embodiment, the push ball frame 3 is detachably connected with the push ball rod 1. Specifically, for example, an inner thread can be processed at the end of the push ball rod 1, and the push ball frame 3 is connected with the push ball rod 1 through the outer thread of the bolt and the inner thread of the push ball rod 1 after being welded with the bolt. By adopting this structure, in different working conditions, the size of the pig or detection device can be different. By adopting the detachable connection mode, the push ball frame 3 and the wheel sliding mechanism can be adjusted according to different pipe diameters and the size of the pig / detection device, so as to improve the applicability and universality of the push ball tool, and the push ball tool has strong universality and adaptability, and is suitable for pipeline pigging and detection operations of natural gas, petroleum, chemical industry and the like.

[0058] Further, as shown in FIG. 6, the push ball frame 3 can be connected with the push ball rod 1 through a wheel sliding mechanism 4. The wheel sliding mechanism 4 can be connected with the push ball frame 3 through a wheel 41, and the wheel 41 can be connected with the push ball rod 1 through a wheel shaft 42. The wheel sliding mechanism 4 can be connected with the push ball frame 3 through a wheel 41, and the wheel 41 can be connected with the push ball rod 1 through a wheel shaft 42. The wheel sliding mechanism 4 can be connected with the push ball frame 3 through a wheel 41, and the wheel 41 can be connected with the push ball rod 1 through a wheel shaft 42. Figure 1 、 Figure 2 、 Figure 3 、 Figure 5As shown, the ball-pushing frame 3 includes a first frame 31, which is fixedly connected to a second frame 32 via several connecting rods 33. The second frame 32 is connected to the ball-pushing stick 1. Specifically, the first frame 31 and the second frame 32 can be circular ring structures. The first frame 31 and the second frame 32 are fixed together by the connecting rods 33, making the ball-pushing frame 3 a structurally stable whole. During use, it can better cover and support the cleaning device or detection equipment, ensuring that it maintains a stable posture during the pushing process, preventing deviation or tilting, and improving the accuracy and success rate of the ball-pushing operation.

[0059] Furthermore, such as Figure 5 As shown, the inner diameter of the first frame 31 is the same as the inner diameter of the second frame 32, and the first frame 31 and the second frame 32 are parallel. Correspondingly, the connecting rods 33 can also be set to be parallel to each other. Specifically, the inner diameters of the first frame 31 and the second frame 32 can be set to 140mm or any other arbitrary inner diameter. It is foreseeable that the inner wall of the ball-pushing frame 3 provided in this embodiment can match the shape of the pig or detection equipment to ensure that the equipment is always in the center position during the ball-pushing process, reducing frictional resistance and the risk of ball jamming.

[0060] The first frame 31 and the second frame 32 have the same inner diameter and are arranged in parallel, so that the entire ball-pushing frame 3 forms a symmetrical structure, avoiding deformation or tilting caused by uneven force and improving the stability of the ball-pushing operation; the double frames with the same inner diameter can provide consistent guidance, so that the pig or detection equipment always stays in the center position during the pushing process, avoiding deviation or jamming, and improving the smoothness and success rate of the ball-pushing operation.

[0061] Furthermore, the second frame 32 is connected to the putter 1 via at least three support rods 34. One end of each support rod 34 is connected to the putter 1, and the other ends of each support rod 34 are evenly distributed within the second frame 32. Figure 5 For example, Figure 5 The three support rods 34 form a structure similar to a regular triangular pyramid. One vertex of the three support rods 34 can be welded to the same bolt and then detachably connected to the pusher rod 1 through the bolt. The other points of the three support rods 34 are evenly distributed on the annular second frame 32.

[0062] At least three support rods 34 are evenly distributed, forming a stable cone-like support structure between the push rod 1 and the second frame 32, preventing frame shaking or deformation due to uneven force during the push process and improving operational stability; one end of each support rod 34 is connected to the push rod 1, ensuring that the push frame 3 and the push rod 1 always remain coaxial, ensuring that the pig or detection equipment moves along the correct trajectory during the push process, avoiding deviation or jamming, and improving the accuracy of the push operation.

[0063] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
