Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically to a ball receiving and launching device with ball receiving and launching position detection function. Background Technology

[0002] High-pressure pipeline pig launching and receiving devices, also known as pig launching and receiving cylinders, are pipeline accessories widely used in pipelines transporting various media. They are typically installed at both ends of the main pipeline for launching and receiving pigs. Before pipeline commissioning, they are used for pig scavenging and line cleaning, and after commissioning, for dewaxing, oil removal, and descaling. The launching device is generally made of steel pipe of the same diameter as the pipeline to be cleaned. The front end has a flange cover and an air inlet, and the rear end is used to connect to the pipeline, which can be welded or flanged. Existing technical solutions make it inconvenient to monitor the real-time position of the launching and receiving pigs. If the launching and receiving pigs are inside the receiving cylinder and obstructed, continued pressurization into the pipeline can easily lead to overpressure damage to the pipeline or the launching and receiving pigs. Furthermore, existing technical solutions make it inconvenient to remove the launching and receiving pigs from the receiving cylinder. Utility Model Content

[0003] The main purpose of this invention is to provide a device that can detect the position of the pig and facilitate the removal of the pig from the pig receiving and launching tube.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A ball receiving and launching device with ball receiving and launching position detection function includes a ball tube, which is fixedly and sealed to a connecting tube through an eccentric conical shell. An air tube is fixedly connected to the ball tube circumferentially. A head is detachably and fixedly and sealed to the end of the ball tube away from the eccentric conical shell. A ranging radar is fixedly and sealed to the head. The ranging radar is electrically connected to a transmitter. The transmitter is communicatively connected to a handheld terminal.

[0006] It also includes a ball retrieval assembly, which includes a pull rod. A clamping component is provided on one end of the pull rod. A blind hole is opened at the end of the pig facing its direction of movement in the pipeline. A retaining ring is fixed in the opening of the blind hole. After the clamping component enters the blind hole, it can be blocked by the retaining ring. After the clamping component is blocked by the retaining ring, the pig can be pulled out of the pig cylinder by the pull rod.

[0007] Specifically, the holding assembly includes an elongated groove on the pull rod, with two stops inside the groove. The two stops are connected by a tension spring, and one end of each stop is rotatably connected to the pull rod. An electric push rod is fixed inside the elongated groove, with its axis parallel to the pull rod's axis. A cone is fixed to the telescopic end of the electric push rod, with the tip of the cone located between the two stops. When the electric push rod extends, the cone causes the two stops to rotate outward from the elongated groove.

[0008] Specifically, the end of the stop block furthest from the cone block is rotatably connected to the pull rod.

[0009] Specifically, a drain pipe is fixedly connected to the lower end of the ball cylinder.

[0010] Specifically, the two stops are symmetrically arranged according to the axis of the pull rod.

[0011] Specifically, an electronic tracker is installed on the end of the pigging ball that is opposite to its direction of movement within the pipeline.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By linking the ranging radar integrated into the end cap with a handheld terminal, the distance change data of the pig inside the pig tube can be obtained in real time. Operators can accurately judge the movement status of the pig (whether it has been launched successfully, whether it has entered the receiving tube). This design solves the problem that traditional devices cannot monitor the position of the pig in real time, avoids the risk of pipeline or pig overpressure damage caused by continuous pressurization due to pig jamming, and significantly improves operational safety.

[0014] 2. The electric push rod of the clamping assembly drives the cone block to push open the symmetrical stop blocks, causing them to unfold outward and engage with the retaining ring inside the blind hole of the pigging ball. Automatic reset is achieved via a tension spring. This design ensures fast and reliable clamping action, and the retaining ring blocking mechanism prevents disengagement during pulling, significantly improving the success rate of pigging ball retrieval. The pigging ball has uniformly sized blind holes at both ends to adapt to different retrieval needs, offering strong versatility and reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1 As shown, a ball receiving and launching device with ball receiving and launching position detection function includes a ball tube 1, with a drain pipe fixedly connected to the lower end of the ball tube 1. The ball tube 1 and the connecting pipe 3 are fixedly and sealedly connected through an eccentric conical shell 2. An air pipe 5 is fixedly connected to the circumference of the ball tube 1. A cap 6 is detachably and fixedly and sealedly connected to the end of the ball tube 1 away from the eccentric conical shell 2. A ranging radar 7 is fixedly and sealedly connected to the cap 6. The ranging radar 7 is electrically connected to a transmitter 8, and the transmitter 8 is communicatively connected to a handheld terminal.

[0023] The ball tube 1 is connected to the pipe, and one of the ball receiving and launching devices is a ball launching device, and the other ball receiving and launching device is a ball receiving device.

[0024] Open the end cap 6 on the ball tube 1 of the serving device, and send the cleaning ball 4 into the ball tube 1 of the serving device. Then install the end cap 6 onto the ball tube 1 of the serving device. Open the air pipe 5 and the drain pipe that are connected to the ball tube 1 of the receiving device.

[0025] Compressed air is supplied into the air pipe 5, which is connected to the ball tube 1 of the launching device. Under the action of pressure difference, the pigging ball 4 can move into the pipe. When launching, the ranging radar 7 on the launching device transmits the distance information between itself and the pigging ball 4 to a handheld terminal through the transmitter 8. The operator can judge the movement status of the pigging ball 4 based on the change in the distance information between the ranging radar 7 and the pigging ball 4, and thus determine whether the pigging ball 4 has been launched successfully.

[0026] When the pigging ball 4 enters the retrieval device, the ranging radar 7 on the retrieval device transmits the distance information between itself and the pigging ball 4 to a handheld terminal via transmitter 8. The operator can then determine the movement status of the pigging ball 4 based on the changes in the distance information between the ranging radar 7 and the pigging ball 4, and thus determine whether the pigging ball 4 has been successfully retrieved. Successful retrieval allows for timely cessation of pressurization into the pipeline, preventing damage to the pipeline or the pigging ball 4 due to excessive pressure.

[0027] An electronic tracker 15 is installed on the end of the pigging ball 4 that is opposite to its direction of movement within the pipeline. This facilitates locating the pigging ball 4 in the pipeline when it becomes stuck.

[0028] Example 2: Based on Example 1, referring to... Figures 2-5 As shown, it also includes a ball-retrieving component.

[0029] The pig-retrieving assembly includes a lever 9, with a clamping component at one end of the lever 9. The pig 4 has a blind hole 401 at the end facing its direction of movement in the pipeline. A retaining ring 402 is fixed inside the opening of the blind hole 401. After the clamping component enters the blind hole 401, it can be blocked by the retaining ring 402. After the clamping component is blocked by the retaining ring 402, the pig 4 can be pulled out of the pig cylinder 1 by the lever 9.

[0030] The retaining assembly includes an elongated slot 10 formed on the pull rod 9. Two stops 13 are disposed within the slot 10, symmetrically arranged around the axis of the pull rod 9. The two stops 13 are connected by a tension spring 14, and one end of each stop 13 is rotatably connected to the pull rod 9. An electric push rod 11 is fixed within the slot 10. The axis of the electric push rod 11 is parallel to the axis of the pull rod 9. A cone 12 is fixed to the telescopic end of the electric push rod 11, with the tip of the cone 12 located between the two stops 13. The end of each stop 13 away from the cone 12 is rotatably connected to the pull rod 9. When the electric push rod 11 extends, the cone 12 causes the two stops 13 to rotate outward from the slot 10.

[0031] After successful pig collection, disassemble the end cap 6 connected to the pig collection device's cylinder 1. This causes the pull rod 9 to move to the right, then concentrically with the pig collection device's cylinder 1, causing the pull rod 9 to move to the left and enter the pig collection device's cylinder 1. When the free end of the pull rod 9 enters the blind hole 401 on the right side of the pig 4 and abuts against the bottom of the blind hole 401, activate the electric push rod 11, causing the cone block 12 to move to the left. At this time, the two stops 13 move outward from the long groove 10. After the two stops 13 move outward from the long groove 10, the retaining ring 402 can block the stops 13, allowing the pig 4 to be pulled out of the pig collection device's cylinder 1 via the pull rod 9.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
