Description

Technical Field

[0001] This utility model belongs to the technical field of oil pipeline testing equipment for oil development, and specifically relates to an oil pipeline testing equipment for oil development. Background Technology

[0002] During oil extraction, extracted oil or natural gas needs to be transported to the surface through pipelines. When pipelines are used for a long time, they need to be inspected and maintained. The main inspection is usually to check for magnetic leakage inside the pipeline. A magnetic leakage detector is used for the inspection. The magnetic leakage detection equipment consists of a power section, a detection section, a computer section, and a battery section. During the inspection, the staff needs to place the detection equipment directly on the rack, then transport the rack to the pipeline opening, and then lift the detection equipment into the pipeline for inspection.

[0003] Chinese Patent Application No. CN202323472609.2 discloses an auxiliary-fixing oil pipeline inspection device for oil drilling, relating to the technical field of oil pipeline inspection equipment for oil drilling. It includes an inspection machine and a fixing device. The inspection machine is secured below a fixing device, and a lifting assembly for adjusting the machine's height is located below the fixing device. The fixing device includes a positioning base, a first arc-shaped block, a second arc-shaped block, and a positioning nut. The first arc-shaped block is located inside the positioning base. This auxiliary-fixing oil pipeline inspection device, by using the fixing device, allows the inspection machine to be placed inside the first arc-shaped block when it needs to be moved to the pipe opening. Then, the second arc-shaped block is placed over it, and finally, the positioning nut is used to secure it. This prevents the inspection machine from falling during transportation due to lack of securing on the shelf.

[0004] 1. The aforementioned patent has the problem of not being able to push the testing machine. After the device moves the testing machine to the pipe opening, the second arc block needs to be opened and then manually pushed, which is cumbersome and inefficient. 2. The aforementioned patent has the problem of not being able to fix the positioning base to the pipe opening. After aligning the device with the oil pipe opening, the positioning base needs to be fixed to prevent the device from sliding and the testing machine from entering the oil pipe.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Specifically, the pushing mechanism 3 includes an electric slide rail 31, a sliding frame 32, a lower arc plate 33, an upper arc plate 34, and a pushing assembly 35. The bottom of the electric slide rail 31 is fixedly connected to the first arc block 2. The sliding frame 32 is provided on the side of the electric slide rail 31. The lower arc plate 33 is fixedly connected to the top of the sliding frame 32. The pushing assembly 35 is provided on the side of the second arc block 5 above the lower arc plate 33. The upper arc plate 34 is provided on one side of the pushing assembly 35.

[0025] By adopting the above technical solution, the electric slide rail 31 drives the sliding frame 32 to slide, thereby driving the lower arc plate 33 to move on the surface of the electric slide rail 31. The detection machine 4 can be placed on the lower arc plate 33, thereby pushing the detection machine 4 into the oil pipe. The push component 35 drives the upper arc plate 34 to move downward, so that the upper arc plate 34 and the lower arc plate 33 can clamp the detection machine 4.

[0026] Specifically, the push-down assembly 35 includes a guide rail 351, a slide plate 352, pulleys 353, and an electric push rod 354. The slide plate 352 is slidably connected to the inner side of the guide rail 351, pulleys 353 are provided on both sides of the slide plate 352, and the electric push rod 354 is fixedly connected to the bottom of the slide plate 352.

[0027] By adopting the above technical solution, the top of the upper arc plate 34 is connected to the output end of the electric push rod 354. The electric push rod 354 drives the upper arc plate 34 to extend downward, thereby resisting the detection machine 4. When the lower arc plate 33 moves under the drive of the electric slide rail 31, the detection machine 4 will slide together, thereby driving the slide plate 352 to slide in the guide rail 351. The pulley 353 reduces the sliding resistance of the slide plate 352.

[0028] Specifically, rubber protrusions 36 are fixedly connected to the sides of both the lower arc plate 33 and the upper arc plate 34.

[0029] By adopting the above technical solution, the rubber protrusions 36 on the surfaces of the two arc plates can increase friction, making it less likely for the testing machine 4 to fall off.

[0030] In this embodiment, the electric slide rail 31 is connected to an external power source. The second arc-shaped block 5 is removed from the positioning base 1, and the testing machine 4 is placed on the lower arc plate 33. The second arc-shaped block 5 is fixed to the positioning base 1 using the positioning nut 7. The device is moved to the inlet position of the oil pipe. The electric slide rail 31 drives the sliding frame 32 to slide, thereby moving the lower arc plate 33 on the surface of the electric slide rail 31. The testing machine 4 can be placed on the lower arc plate 33, allowing it to be pushed into the oil pipe. The top of the upper arc plate 34 is connected to the output end of the electric push rod 354. The push rod 354 drives the upper arc plate 34 to extend downward, thereby blocking the detection machine 4. When the electric slide rail 31 drives the lower arc plate 33 to move, the detection machine 4 will slide together, thereby driving the slide plate 352 to slide in the guide rail 351. The pulley 353 reduces the sliding resistance of the slide plate 352, thereby allowing the upper arc plate 34 and the lower arc plate 33 to clamp the detection machine 4. The rubber protrusions 36 on the surface of the two arc plates can increase friction, making it difficult for the detection machine 4 to fall off. By driving the lower arc plate 33 to move through the electric slide rail 31, the detection machine 4 can be automatically pushed into the oil pipe, improving work efficiency.

One side of the hydraulic cylinder 62 is fixedly connected to the clamping plate 63. The outside of the clamping plate 63 is provided with a suction cup 64.

[0033] By adopting the above technical solution, there are two fixing frames 61, which are located at both ends of the same side of the positioning base 1.

The suction cup 64 is attached to the surface of the oil pipe to make the clamping plate 63 clamp more stably.

[0034] Specifically, an oil-absorbing pad 65 is provided on the side of the clamp 63 away from the suction cup 64.

[0035] By adopting the above technical solution, the oil-absorbing pad 65 is made of kapok fiber, which can prevent oil stains from sliding onto the clamp 63 during the fixing process and affecting the fixing effect.

[0036] In this embodiment, there are two fixing frames 61, located at both ends of the same side of the positioning base 1. When the detection machine 4 faces the oil pipe, the hydraulic cylinder 62 drives the clamping plate 63 to move, so that the two clamping plates 63 clamp the oil pipe to achieve the fixing effect. The suction cup 64 is attached to the surface of the oil pipe to make the clamping plate 63 clamp more stably. The oil-absorbing pad 65 is made of kapok fiber, which can prevent oil stains from sliding onto the clamping plate 63 during the fixing process and affecting the fixing effect. By driving the clamping plate 63 to clamp the oil pipe through the hydraulic cylinder 62, the purpose of fixing the positioning base 1 can be achieved.

The second arc-shaped block 5 is fixed to the positioning base 1 using the positioning nut 7. The device is moved to the inlet position of the oil pipe. The electric slide rail 31 drives the sliding frame 32 to slide, thereby moving the lower arc plate 33 on the surface of the electric slide rail 31. The testing machine 4 can be placed on the lower arc plate 33, allowing it to be pushed into the oil pipe. The top of the upper arc plate 34 is connected to the output end of the electric push rod 354. The electric push rod 354 drives the upper arc plate 34 to extend downwards, thus blocking the testing machine 4. When the electric slide rail 31 drives the lower arc plate 33 to move, the testing machine 4 slides along with it, thereby causing the sliding plate 352 to slide within the guide rail 351. The pulley 35... 3. Reduce the sliding resistance of the sliding plate 352, so that the upper arc plate 34 and the lower arc plate 33 can clamp the inspection machine 4. The rubber protrusions 36 on the surface of the two arc plates can increase friction, making it less likely for the inspection machine 4 to fall off. The lower arc plate 33 can be moved by the electric slide rail 31, which can automatically push the inspection machine 4 into the oil pipe, improving work efficiency. There are two fixing frames 61, located at both ends on the same side of the positioning base 1. When the inspection machine 4 faces the oil pipe, the hydraulic cylinder 62 drives the clamping plate 63 to move, so that the two clamping plates 63 clamp the oil pipe to achieve the fixing effect. The suction cup 64 can be attached to the surface of the oil pipe to make the clamping plate 63 clamp more stably. The oil absorption pad 65 is made of kapok fiber, which can prevent oil stains from sliding onto the clamping plate 63 during the fixing process, affecting the fixing effect. The clamping plate 63 is driven by the hydraulic cylinder 62 to clamp the oil pipe, which can achieve the purpose of fixing the positioning base 1.
