Description

Technical Field

[0001] The utility model relates to the field of oil and gas pipeline maintenance, and particularly relates to a tool for a pig launcher and receiver barrel. Background Art

[0002] In oil and gas transportation, in order to ensure the smoothness of oil and gas pipelines, reduce the internal corrosion of oil and gas pipelines, and improve the oil and gas transportation efficiency, it is necessary to regularly clean the pipelines. For relatively long oil and gas pipelines, a pigging system is generally used for cleaning, that is, a pig is set at the upstream station, and the pig is pushed by an oil and gas medium. The pig pushes the impurities in the pipeline to the downstream station, and the pig is received at the downstream station and various impurities are collected.

[0003] However, as Figure 1 shown, the pig launcher and receiver barrel of the pigging system is similar to a tee structure, and a relatively long empty pipe section 101 is reserved for collecting stains and pigs. The pig needs to be put into or taken out from the empty pipe section 101; during pigging operation, if the pig does not enter the flow range of the oil and gas medium, it will always stay in the empty pipe section 101 and cannot be pigged downstream; during pig receiving operation, the pig may be too far away from the pigging port 102 and it is difficult to take it out of the pig launcher and receiver barrel; in the face of the above situations, operators usually use tools such as wooden sticks to change the position of the pig, and the pigging operation efficiency is relatively low; currently, there is no unified tool to change the position of the pig in the pig launcher and receiver barrel.

[0004] Therefore, there is an urgent need for a technical solution at present to solve the technical problem that the current pig is difficult to reach the predetermined position in the pig launcher and receiver barrel. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a tool for a pig launcher and receiver barrel for the technical problem that the current pig is difficult to reach the predetermined position in the pig launcher and receiver barrel.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A tool for a pig launcher and receiver barrel includes a rod body, a pig pushing device and a pig hooking device. One end of the rod body is connected to the pig pushing device, and the other end is connected to the pig hooking device. The rod body is slidably arranged on a support frame. The support frame is provided with a limiting member, and the limiting member can be connected with the rod body in a limiting manner. The support frame can be slidably connected to the pipe wall of the pig launcher and receiver barrel.

[0008] The utility model discloses a tool for a ball receiving and sending cylinder, which pushes a pipe cleaning ball through a rod body, thereby extending the operating distance of the pipe cleaning ball by an operator; a ball pushing device and a ball hooking device are respectively arranged at both ends of the rod body, the ball pushing device can push the pipe cleaning ball to a serving position when performing a serving operation, and the ball hooking device can hook the pipe cleaning ball when receiving the ball so that the pipe cleaning ball is brought out of the ball receiving and sending cylinder along with the rod body; a support frame is slidably arranged on the rod body, and the support frame suspends the rod body in the air, thereby reducing the contact surface between the rod body and the ball receiving and sending cylinder, and avoiding damage to the ball receiving and sending cylinder; the support frame is slidably connected to the pipe wall of the ball receiving and sending cylinder through the support frame The support frame supports the rod body at the axial position of the ball-receiving and sending cylinder, and is slidably connected to the ball-receiving and sending cylinder by the support frame, so that the ball-receiving device can more easily push the pipe-cleaning ball, and the ball-hooking device can more easily hook the pipe-cleaning ball and pull it out of the ball-receiving and sending cylinder; the support frame can slide on the rod body to change the position of the support frame on the rod body, and the limiter can fix the support frame at any position of the rod body; when serving the ball, the support frame is moved to the side close to the ball-pushing device, and when receiving the ball, the support frame is moved to the side of the ball-hooking device.

[0009] As a preferred solution of the utility model, the ball hook device includes a hook portion and a straight rod portion, one end of the straight rod portion is connected to the rod body, and the other end is connected to the hook portion. The straight rod portion can extend the position of the hook portion to be longer, so that the hook portion is easier to hook the pipe cleaning ball when in use. The straight rod portion has a smaller diameter, which can avoid the rod body blocking the line of sight and make it easier to hook the pipe cleaning ball.

[0010] As a preferred solution of the utility model, the ball pushing device includes a frame and a ball pushing platform, the frame is connected to the ball pushing platform, the frame is connected to the rod, and the ball pushing platform can be adapted to abut against the pipe cleaning ball. The contact surface between the ball pushing platform and the pipe cleaning ball is large, so that the pipe cleaning ball can be pushed more easily by the rod; by setting the frame, the center of the ball pushing platform is always located on the axis of the rod, and the operator can more easily push the pipe cleaning ball to the ball sending position of the ball receiving and sending barrel.

[0011] As a preferred solution of the utility model, the ball-pushing platform includes a circular ring structure, the diameter of which is smaller than the diameter of the pipe cleaning ball. The ball-pushing platform is a circular ring structure, which is lighter and easier for operators to operate; the circular ring structure has sufficient contact area with the pipe cleaning ball, so that the pipe cleaning ball is evenly stressed and can be pushed more easily.

[0012] As a preferred solution of the utility model, the frame body includes a plurality of support rods, one end of each support rod is connected to the circular ring structure, and the other end is connected to the rod body. The circular ring structure and the rod body are connected by a plurality of support rods, thereby reducing the overall mass of the frame body; the support rods and the circular ring structure form a conical structure, and the tip of the conical structure is connected to the rod body, so that the axis of the rod body passes through the center of the circular ring structure.

[0013] As a preferred solution of the present utility model, the support frame includes an annular structural member and a support assembly. One end of the support assembly is connected to the annular structural member, and the other end is slidably connected to the pipe wall of the pig launcher and receiver. The rod body is adaptively passed through the annular structural member, and the limiting member is arranged on the annular structural member. By passing the annular structural member through the rod body, the annular structural member can slide to any position on the rod body. A threaded hole is opened on the side wall of the annular structural member, and a bolt is arranged in the threaded hole as the limiting member. The annular structural member is limited to a predetermined position on the rod body by the bolt abutting against the outer wall of the rod body. By the support assembly being slidably connected to the pipe wall of the pig launcher and receiver, the operator can easily push the rod body, facilitating the operator to operate the pig in the pig launcher and receiver.

[0014] As a preferred solution of the present utility model, the support assembly is provided with guide wheels. The guide wheels are located at one end of the support assembly away from the annular structural member, and the guide wheels can abut against the pipe wall of the pig launcher and receiver. By providing the guide wheels, the guide wheels abut against the pipe wall of the pig launcher and receiver, converting the sliding friction into rolling friction. The operator pushes the rod body, causing the guide wheels to rotate, making it more labor-saving when pushing the rod body.

[0015] As a preferred solution of the present utility model, the support assembly includes support bars. The support bars are arranged along the radial direction of the annular structural member. At least two support bars are connected to the annular structural member, and adjacent support bars are spaced apart. Preferably, by arranging two support bars at intervals on the annular structural member, the rod body can stably perform axial reciprocating motion in the pig launcher and receiver. Both support bars are slidably connected to the pipe wall of the pig launcher and receiver. The axis of the rod body coincides with the axis of the pig launcher and receiver.

[0016] As a preferred solution of the present utility model, the ball pushing device is detachably connected to the rod body, and / or the ball hooking device is detachably connected to the rod body. By replacing different ball pushing devices or ball hooking devices, the tools used for the pig launcher and receiver have stronger applicability and can be applicable to different specifications of pigs.

[0017] As a preferred solution of the present utility model, the rod body includes a first section and a second section. The first section is detachably connected to the second section. The first section is connected to the ball pushing device, and the second section is connected to the ball hooking device. By splitting the rod body into the first section and the second section, the ball receiving device and the ball sending device can be used separately. In oil and gas gathering and transportation stations, by splitting the rod body, the ball receiving operation and the ball sending operation can be carried out simultaneously, improving the operation efficiency.

[0018] In summary, due to the adoption of the above technical solutions, the present utility model achieves the following effects:

[0019] 1. The utility model is a tool for a ball receiving and sending cylinder. The rod body pushes the pipe cleaning ball, thereby extending the operating distance of the operator for the pipe cleaning ball. A ball pushing device and a ball hooking device are respectively arranged at both ends of the rod body. The ball pushing device can push the pipe cleaning ball to the serving position when serving, and the ball hooking device can hook the pipe cleaning ball when receiving so that the pipe cleaning ball is brought out of the ball receiving and sending cylinder along with the rod body. A support frame is slidably arranged on the rod body, and the support frame suspends the rod body, thereby reducing the contact surface between the rod body and the ball receiving and sending cylinder, thereby avoiding damage to the ball receiving and sending cylinder. The support frame slides with the pipe wall of the ball receiving and sending cylinder. The rod body is connected so that it can be extended into or pulled out of the sending and receiving ball cylinder along the axis; the support frame supports the rod body at the axial position of the sending and receiving ball cylinder, and the support frame is slidably connected to the sending and receiving ball cylinder, so that the ball collecting device can more easily push the pipe cleaning ball, and the ball hooking device can more easily hook the pipe cleaning ball and pull it out of the sending and receiving ball cylinder; the support frame can slide on the rod body to change the position of the support frame on the rod body, and the limit piece can fix the support frame at any position of the rod body; when serving the ball, the support frame is moved to the side close to the ball pushing device, and when receiving the ball, the support frame is moved to the side of the ball hooking device.

[0020] 2. The utility model is a tool for sending and receiving ball barrels, which has a simple structure, is easy to manufacture and convenient to use. By developing a new type of ball sending and receiving ball barrel tool, the ball sending and receiving work in oil and gas gathering and transportation stations is simplified, and the cleaning balls can be taken out or placed more conveniently, which reduces the difficulty of sending and receiving balls, improves the efficiency of the ball sending and receiving operations, shortens the cleaning time of oil and gas pipelines, improves production efficiency, ensures the safety of oil and gas transportation, and has good economic value and practical value.

Detailed implementation mode

[0029] The following combines the attached drawings to make a detailed description of the present utility model.

[0030] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in combination with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] Embodiment 1

[0032] As Figures 2 - 5 A tool for a ball receiving and sending barrel shown in the figure includes a rod body 1, a ball pushing device 2 and a ball hooking device 3. One end of the rod body 1 is connected to the ball pushing device 2, and the other end is connected to the ball hooking device 3. The rod body 1 is slidably arranged on a support frame 4. The support frame 4 is provided with a limiting member 5. The limiting member 5 can be in limiting connection with the rod body 1. The support frame 4 can be slidably connected to the pipe wall of the ball receiving and sending barrel.

[0033] Specifically, the ball hooking device 3 is composed of a hook-shaped part 31 and a straight rod part 32. The two ends of the straight rod part 32 are respectively connected to the rod body 1 and the hook-shaped part 31. The hook-shaped part 31 can be hooked on the pigging ball. By setting the straight rod part 32, the distance between the rod body 1 and the hook-shaped part 31 is increased, which can avoid the rod body 1 blocking the line of sight of the hook-shaped part 31 during operation, and ensure that the operator can quickly take out the pigging ball during the ball receiving operation.

[0034] Specifically, the ball pushing device 2 is composed of a frame body 22 and a ball pushing platform 21. One end of the frame body 22 is connected to the ball pushing platform 21, and the other end is connected to the end of the rod body 1. The ball pushing platform 21 is a ring-shaped structural member. The frame body 22 is composed of four support rods. One end of the support rod is connected to the ring-shaped structural member, and the other end is connected to the rod body 1. The ring-shaped structural member and the rod body 1 together form a conical structural member, so that the tip of the conical structural member is connected to the end of the rod body 1, thereby ensuring that the axis of the rod body 1 passes through the center of the ring-shaped structural member. The four support rods are arranged in an annular equidistant manner on the ring-shaped structural member, ensuring the balanced force of the ring-shaped structural member and making the ring-shaped structural member not easily deformed. The diameter of the ring-shaped structural member is smaller than the diameter of the pigging ball, so that the ring-shaped structural member can be in contact with the pigging ball to facilitate pushing the pigging ball.

[0035] Specifically, the support frame 4 is composed of an annular structural member 41 and a support assembly 42. One end of the support assembly 42 is connected to the annular structural member 41, and the other end is slidably connected to the pipe wall of the pig launcher and receiver. The rod body 1 passes through the annular structural member 41, enabling the annular structural member 41 to slide on the rod body 1, thereby adjusting the position of the support frame 4 on the rod body 1. The support assembly 42 is composed of two support bars 421. The two support bars 421 are arranged at intervals and extend radially along the annular structural member 41. A guide wheel 43 is provided at the end of the support bar 421 away from the annular structural member 41, making the guide wheel 43 abut against the pipe wall of the pig launcher and receiver. The guide wheel 43 converts sliding friction into rolling friction, enabling the rod body 1 to slide smoothly in its axial direction. An included angle is formed between the two support bars 421, enabling the support bars 421 to support the rod body 1 more stably. The axis of the rod body 1 coincides with the axis of the pig launcher and receiver.

[0036] Preferably, the number of support bars 421 is set to three or more. The arrangement of multiple support bars 421 can better support the rod body 1.

[0037] Preferably, the ball pushing platform 21 is a plate-shaped structural member.

[0038] Preferably, the ball hooking device 3 is a magnetic attraction device, and the magnetic attraction device can be magnetically connected to the pigging ball.

[0039] When using the tool for the pig launcher and receiver in this embodiment to receive the ball, adjust the support frame 4 to one side of the ball hooking device 3. Insert the end of the rod body 1 provided with the ball hooking device 3 into the pig launcher and receiver, making the support frame 4 abut against the pipe wall of the pig launcher and receiver. By adjusting the position of the rod body 1, connect the ball hooking device 3 to the pigging ball, and take out the pigging ball from the pig launcher and receiver when the rod body 1 is withdrawn. When sending the ball, adjust the support frame 4 to one side of the ball pushing device 2. Insert the end of the rod body 1 provided with the ball pushing device 2 into the pig launcher and receiver, making the support frame 4 abut against the pipe wall of the pig launcher and receiver. Push the rod body 1 to make the ball pushing device 2 abut against the pigging ball and push the pigging ball to the ball sending position of the pig launcher and receiver.

[0040] A tool for a pig launcher and receiver can push a pig through a rod body 1, extending the operating distance of an operator to the pig. A ball pushing device 2 and a ball hooking device 3 are respectively arranged at two ends of the rod body 1. The ball pushing device 2 can push the pig to the serving position during serving operation, and the ball hooking device 3 can hook the pig during ball receiving so that the pig is taken out of the pig launcher and receiver along with the rod body 1. A support frame 4 is slidably arranged on the rod body 1. The support frame 4 suspends the rod body 1, reducing the contact area between the rod body 1 and the pig launcher and receiver, and avoiding damage to the pig launcher and receiver. By slidably connecting the support frame 4 with the pipe wall of the pig launcher and receiver, the rod body 1 can extend into or be pulled out of the pig launcher and receiver along the axis. The support frame 4 supports the rod body 1 at the central position of the pig launcher and receiver. By slidably connecting the support frame 4 with the pig launcher and receiver, the ball receiving device can more easily push the pig, and the ball hooking device 3 can more easily hook and pull out the pig from the pig launcher and receiver. The support frame 4 can slide on the rod body 1 to change the position of the support frame 4 on the rod body 1, and a limiting member 5 can fix the support frame 4 at any position on the rod body 1. When serving, the support frame 4 is moved to the side close to the ball pushing device 2, and when receiving the ball, the support frame 4 is moved to the side of the ball hooking device 3
