Description

Technical Field

[0001] This utility model relates to the field of ball throwers, specifically a pusher-type ball thrower. Background Technology

[0002] In the field of oil drilling, the pigging device is a key piece of equipment used for cleaning and maintaining oil pipelines. It mainly works with tools such as pigging balls, and through specific structural design and operation methods, it sends the pigging ball into the interior of the oil pipeline to clean the inner wall of the pipeline, ensuring the normal operation of the oil pipeline and the efficiency of oil transportation.

[0003] During long-term oil transportation, oil stains, impurities, and scale accumulate on the inner walls of oil pipelines, affecting the transportation efficiency. Oil pipeline cleaning devices, in conjunction with appropriate cleaning balls, can easily and accurately complete pipeline cleaning tasks. After being inserted into the oil pipeline, the cleaning ball moves forward with the medium inside the pipe. During this movement, the cleaning ball exerts a squeezing effect on the inner wall of the oil pipeline. Utilizing the friction and pressure generated by this squeezing, the oil stains, impurities, and scale adhering to the inner wall of the oil pipeline are scraped off and carried away, thus achieving the purpose of cleaning the inside of the oil pipeline.

[0004] Since the cleaning effect of the pipeline cleaning ball relies on squeezing the inner wall of the oil pipe, the diameter of the cleaning ball must be larger than the diameter of the inner wall of the oil pipe. This is to ensure that there is sufficient squeezing force between the cleaning ball and the inner wall of the oil pipe, and to ensure the thoroughness of the cleaning work. However, it is precisely because the diameter of the cleaning ball is larger than the diameter of the inner wall of the oil pipe that the cleaning ball faces great difficulties when it is deployed. It is difficult for personnel to directly and smoothly deploy it into the oil pipe. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a pusher-type ball-throwing method to solve the technical problem that it is difficult to throw the pigging ball into the oil pipeline.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a push rod type ball thrower, comprising a ball throwing tube, an oil supply pipe connected to the outer wall of the ball throwing tube, a ball thrower installed inside the ball throwing tube, a hydraulic cylinder connected to the top of the ball thrower, a connecting block installed at the end of the hydraulic cylinder, a ball hole opened at the bottom of the inside of the ball thrower, a ball feeding pipe connected to the outer wall of the ball throwing tube, a ball pushing plate provided inside the ball feeding pipe, a ball installed inside the ball feeding pipe, a push rod movably connected to one side of the ball pushing plate, a fixing plate sleeved on the outer wall of the push rod, and a driving block provided on the top of the fixing plate.

[0007] By adopting the above technical solution, the problem of the pigging ball being difficult to place into the oil pipeline is solved. The hydraulic cylinder drives the ball launcher to rise until the ball hole inside the launcher is aligned with the end of the ball delivery pipe. When the ball is placed into the ball delivery pipe, the operator pushes the ball into the ball hole inside the launcher using a pusher plate. When the pusher plate has difficulty pushing the ball, the operator rotates the handle to slowly push the pusher plate, thereby pushing the ball into the launcher. The hydraulic cylinder pushes the launcher downward, so that the medium inside the oil pipeline can squeeze and push the ball in the launcher into the oil pipeline.

[0008] The present invention is further configured such that the inner wall diameter of the ball feeding pipe and the ball hole is equal to the diameter of the ball, and the inner wall diameter of the oil delivery pipe is smaller than the diameter of the ball.

[0009] Preferably, the inner diameter of the ball delivery pipe and the ball hole is equal to the diameter of the ball, so that the ball can easily slide in the ball delivery pipe and the ball hole, while the inner diameter of the oil delivery pipe is smaller than the diameter of the ball, so that the ball can squeeze to clean the inside of the oil delivery pipe.

[0010] The present invention is further configured such that a connecting rod is connected to the bottom of the ball thrower, and a sealing plug is fixed to the end of the connecting rod.

[0011] Preferably, when the ball launcher rises to its highest position, the ball launcher drives the sealing plug to rise synchronously through the connecting rod at the bottom. The sealing plug blocks the medium inside the oil pipeline, preventing the medium from flowing into the bottom of the ball launcher.

[0012] The present invention is further configured such that the length of the connecting rod is greater than the inner diameter of the oil pipeline, and the ball-throwing pipe is equipped with an air valve.

[0013] Preferably, when the ball launcher rises to its highest position, the length of the connecting rod is just enough to allow the sealing plug to block the medium in the oil pipeline, while the air valve installed at the bottom of the ball launcher releases the gas at the bottom of the sealing plug to the outside.

[0014] The present invention is further configured such that a handle is installed at the end of the push rod, and the push rod is threadedly connected to the drive block.

[0015] Preferably, when the operator drives the push rod to rotate via the handle, the push rod continues to push the ball-pushing plate.

[0016] The present invention is further configured such that two sets of protrusions are fixed on the outer wall of the fixing plate, and a lead screw is provided on one side of the protrusions; and two sets of fixing rings are installed on the top outer wall of the ball feeding tube.

[0017] Preferably, when the operator cannot push the ball into the ball-throwing device using the handle, the screw is fixed to one side of the fixed ring with bolts, so that the fixed plate will not rotate when the operator drives the push rod to move the ball-throwing device by rotating the handle.

[0018] The present invention is further configured such that a groove is provided on one side of the ball-pushing plate, and the diameter of the groove is smaller than the diameter of the ball.

[0019] Preferably, when the ball pusher plate contacts the ball, the groove on the ball pusher plate can correct the ball to the central axis of the ball delivery tube.

[0020] The present invention is further configured such that a sealing cap is movably installed at the top of the ball delivery tube, and the ball delivery tube is inclined.

[0021] Preferably, the ball delivery tube is inclined so that the medium in the ball hole inside the ball thrower will not flow out through the ball delivery tube.

[0022] In summary, the present invention has the following main advantages: 1. This utility model solves the problem of difficulty in placing the cleaning ball into the oil pipeline by setting up a ball-throwing tube, a ball-throwing device, a ball hole, a ball-pushing plate, a push rod, and a fixing plate. The hydraulic cylinder drives the ball-throwing device to rise until the ball hole inside the ball-throwing device is aligned with the end of the ball-delivery tube. When the ball is placed into the ball-delivery tube, the operator pushes the ball into the ball hole inside the ball-throwing device using the ball-pushing plate. When the ball-pushing plate has difficulty pushing the ball, the operator rotates the handle to slowly push the push rod, thereby pushing the ball into the ball-throwing device. The hydraulic cylinder pushes the ball-throwing device downward, so that the medium inside the oil pipeline can squeeze and push the ball in the ball-throwing device into the oil pipeline.

[0023] 2. This utility model, by setting up a ball feeding tube, a fixing ring, a fixing plate, and a lead screw, allows the lead screw to be fixed to one side of the fixing ring when the operator cannot push the ball into the ball thrower by using the handle. This ensures that the fixing plate will not rotate when the operator drives the pusher to move the ball throwing plate by rotating the handle. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Please see Figure 1 — Figure 6 The system includes a ball-feeding tube 1, an oil delivery pipe 101 connected to the outer wall of the ball-feeding tube 1, a ball-feeding device 3 installed inside the ball-feeding tube 1, a hydraulic cylinder 4 connected to the top of the ball-feeding device 3, a connecting block 401 installed at the end of the hydraulic cylinder 4, a ball hole 301 opened at the bottom of the inside of the ball-feeding device 3, a ball-feeding tube 2 connected to the outer wall of the ball-feeding tube 1, a ball-pushing plate 702 installed inside the ball-feeding tube 2, a ball 6 installed inside the ball-feeding tube 2, a push rod 701 movably connected to one side of the push rod 702, a fixing plate 5 sleeved on the outer wall of the push rod 701, and a drive block 503 installed on the top of the fixing plate 5. This system solves the problem of the cleaning ball being difficult to place into the oil pipe. The problem is that the hydraulic cylinder 4 drives the ball launcher 3 to rise until the ball hole 301 inside the ball launcher 3 is aligned with the end of the ball delivery pipe 2. When the ball 6 is launched into the ball delivery pipe 2, the operator pushes the ball 6 into the ball hole 301 inside the ball launcher 3 using the ball pusher plate 702. When the ball pusher plate 702 has difficulty pushing the ball 6, the operator rotates the handle 7 to make the pusher rod 701 slowly push the ball pusher plate 702, thereby pushing the ball 6 into the ball launcher 3. The hydraulic cylinder 4 pushes the ball launcher 3 downward, so that the medium inside the oil delivery pipe 2 can squeeze and push the ball 6 in the ball launcher 3 into the oil delivery pipe 101.

[0029] For details regarding the above embodiments, please refer to [link / reference]. Figure 4The inner diameter of the ball feeding pipe 2 and the ball hole 301 is equal to the diameter of the ball 6, and the inner diameter of the oil delivery pipe 101 is smaller than the diameter of the ball 6. The inner diameter of the ball feeding pipe 2 and the ball hole 301 is equal to the diameter of the ball 6, which allows the ball 6 to slide easily in the ball feeding pipe 2 and the ball hole 301. The inner diameter of the oil delivery pipe 101 is smaller than the diameter of the ball 6, which allows the ball 6 to squeeze and clean the inside of the oil delivery pipe 101.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The bottom of the ball launcher 3 is connected to a connecting rod 302, and a sealing plug 303 is fixed to the end of the connecting rod 302. When the ball launcher 3 rises to the highest position, the ball launcher 3 drives the sealing plug 303 to rise synchronously through the connecting rod 302 at the bottom. The sealing plug 303 blocks the medium inside the oil pipe 101 to prevent the medium from flowing into the bottom of the ball launcher pipe 1.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2 The length of the connecting rod 302 is greater than the inner diameter of the oil pipe 101. The ball-throwing pipe 1 is equipped with an air valve 8. When the ball thrower 3 rises to the highest position, the length of the connecting rod 302 is just enough to make the sealing plug 303 block the medium in the oil pipe 101. The air valve 8 installed at the bottom of the ball-throwing pipe 1 releases the gas at the bottom of the sealing plug 303 to the outside.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 A handle 7 is installed at the end of the push rod 701. The push rod 701 is threadedly connected to the drive block 503. When the person drives the push rod 701 to rotate through the handle 7, the push rod 701 continues to push the ball-pushing plate 702.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 Two sets of protrusions 501 are fixed on the outer wall of the fixed plate 5, and a lead screw 502 is provided on one side of the protrusion 501. Two sets of fixing rings 202 are installed on the top outer wall of the ball feeding tube 2. When the personnel cannot push the ball 6 into the ball throwing device 3 by the push plate 702 through the handle 7, the lead screw 502 is fixed to one side of the fixing ring 202 with bolts, so that when the personnel drive the push rod 701 to push the push plate 702 by rotating the handle 7, the fixed plate 5 will not rotate.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 6 A groove 703 is provided on one side of the ball pusher plate 702, and the diameter of the groove 703 is smaller than the diameter of the ball 6. When the ball pusher plate 702 contacts the ball 6, the groove 703 on the ball pusher plate 702 can correct the ball 6 to the central axis of the ball delivery tube 2.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 A sealing cap 201 is movably installed at the top of the ball delivery tube 2. The ball delivery tube 2 is inclined so that the medium in the ball hole 301 inside the ball thrower 3 will not flow out through the ball delivery tube 2.

[0036] In practical operation, when the ball 6 needs to be placed into the oil pipe 101, the valve of the air valve 8 is first opened. Then, the hydraulic cylinder 4 lifts the ball thrower 3 upward through the connecting block 401 connected to the end until the center of the ball hole 301 on one side of the ball thrower 3 is on the same straight line as the axis of the ball delivery pipe 2. Then, the personnel flip open the sealing cover 201 at the top of the ball delivery pipe 2 and place the ball 6 into the ball delivery pipe 2. The ball 6 slides down to the connection between the ball hole 301 and the end of the ball delivery pipe 2. Then, the ball pusher plate 702 is inserted into the ball delivery pipe 2. The personnel push the ball pusher plate 702 into the ball delivery pipe 2 through the handle 7. During the pushing process, the screw rods 502 on both sides of the fixing plate 5 are inserted into the two sets of fixing rings 202 on the outer wall of the ball delivery pipe 2. The personnel cannot push the ball 6 into the ball thrower 3 through the ball pusher plate 702 through the handle 7. Then, use bolts to fix the lead screw 502 to one side of the fixing ring 202, manually rotate the handle 7, the handle 7 drives the push rod 701 to rotate. Since the end of the push rod 701 is connected to the drive block 503 on the top of the fixing plate 5 by thread, the person rotates the push rod 701, causing the push rod 701 to push the ball-pushing plate 702 to move, so that the ball 6 stuck at the connection between the ball hole 301 and the ball delivery pipe 2 port is slowly pushed into the ball hole 301. When the ball 6 is completely pushed into the ball hole 301, remove the ball-pushing plate 702 from the ball delivery pipe 2, close the sealing cover 201, and then the hydraulic cylinder 4 pushes the ball thrower 3 downward, so that the central axis of the ball hole 301 is on the same horizontal line as the central axis of the oil delivery pipe 101. The medium inside the oil delivery pipe 101 squeezes and moves the ball 6 in the ball hole 301 into the oil delivery pipe 101. Finally, close the valve of the air valve 8.
