Description

Technical Field

[0001] This invention relates to the field of oil pipeline technology, and more specifically, to an auxiliary device for oil pipeline transportation. Background Technology

[0002] Oil pipelines, also known as pipelines or conduits, are pipeline systems consisting of oil pipes, accessories, and oil pump units. They are used to complete the tasks of oil unloading and transportation. They are divided into types such as internal oil pipelines and long-distance oil pipelines. The transportation processes include isothermal transportation, heated transportation, and sequential transportation.

[0003] According to existing technology, large-scale pipeline projects will use special pipeline transport frames. However, small and medium-sized projects, such as branch lines of mountain oil fields or pipelines of local oil refineries, are still largely limited by cost and transport volume, and still use a simple method of ropes and flatbed trailers. Because mountain and forest transportation is difficult to invest in special equipment due to the irregular routes and small transport volume, the ropes are prone to loosening during transportation due to road bumps, resulting in pipeline slippage and damage. Summary of the Invention

[0004] This invention provides an auxiliary device for oil pipeline transportation. It achieves stable load-bearing through two conveying devices directly below the pipe body. The fixed cylinder and sliding column cooperate to make the pad adapt to the support requirements of the pipe body. The buffer and the air bladder inside the pad can effectively buffer the vibration and impact during transportation. The polyurethane rubber wear-resistant sheet on the air bladder improves wear resistance, thereby solving the problems mentioned in the background art, namely: due to the irregular routes and small single transportation volume in mountainous areas, it is difficult to invest in special equipment. During transportation, the ropes are prone to loosening due to road bumps, resulting in the pipe slipping and falling and being damaged.

[0005] To achieve the above objectives, an auxiliary device for oil pipeline transportation includes a pipe body and two conveying devices. The two conveying devices are located directly below the pipe body. Each conveying device includes a vehicle body located directly below the pipe body. A fixed cylinder is fixedly connected to the upper surface of the vehicle body. Two sliding columns are slidably connected inside the fixed cylinder. A pad is fixedly connected to the upper surface of the two sliding columns. The pad is located at the bottom end of the pipe body. The side wall of the vehicle body is provided with an auxiliary device, which includes a frame located on the side wall of the vehicle body and at the bottom of the tube. The auxiliary device is used to assist the conveying device in supporting the tube.

[0006] In the above technical solution, four buffers are fixedly connected to the upper surface of the vehicle body, the buffers are located directly below the pad, a pull rod is fixedly connected to the side wall of the vehicle body, an airbag is inserted inside the pad, a valve core is fixedly connected to the side wall of the airbag and inserted inside the pad, and a wear-resistant sheet is fixedly connected to the upper surface of the airbag, the wear-resistant sheet being a polyurethane rubber sheet.

[0007] Secondly, the upper surface of the pad is provided with a limiting device, which includes two fixing blocks. The bottom ends of the two fixing blocks are fixedly connected to the upper surface of the pad. A rotating block is rotatably connected to the surface of the fixing blocks. A connecting block is fixedly connected to the upper surface of the rotating block. An elastic band is fixedly connected to the surfaces of the two connecting blocks. The elastic band is located on the surface of the tube body. A compression sleeve is fixedly connected to the surface of the rotating block. The compression sleeve is located on one side of the tube body.

[0008] Furthermore, based on the above, two sleeves are fixedly connected to the upper surface of the frame, and sliding rods are slidably connected inside the sleeves. Top plates are fixedly connected to the upper surfaces of the two sliding rods, and the top plates are located directly below the tube body. Two springs are fixedly connected to the bottom end of the top plate and the upper surfaces of the two sleeves. The springs are sleeved on the surface of the sliding rods. A soft pad is fixedly connected to the upper surface of the top plate. Multiple through holes are opened on the surface of the frame. A connecting plate is fixedly connected to the side wall of the frame. A collar is rotatably connected to the upper surface of the connecting plate. Part of the vehicle body structure is inserted into the connecting plate and the collar. The collar and the inside of the vehicle body are threadedly connected to the mounting bolt. A placement block is fixedly connected to the surface of the sleeve. A threaded post is threadedly connected inside the placement block. A groove is opened on the surface of the sliding rod. A rubber post is provided on the side wall of the threaded post. The threaded post is inserted into the groove.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: In this oil pipeline transportation auxiliary device, stable load-bearing is achieved through two conveying devices directly below the pipe body. The fixed cylinder and sliding column work together to adapt the pad to the pipe body support requirements. The buffer and the airbag inside the pad can effectively buffer the vibration and impact during transportation. The polyurethane rubber wear-resistant sheet on the airbag improves wear resistance. The rotating block, connecting block and elastic band of the limiting device, together with the compression sleeve, can firmly limit the pipe body and prevent displacement.

The threaded column and the slot can fix the position of the sliding rod to adapt to different support heights. The frame is firmly connected to the vehicle body through the connecting plate, collar and mounting bolt. The whole device can achieve stable support, effective buffering and anti-displacement of the oil pipeline, thereby improving the safety and reliability of transportation.

[0012] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0013] Because mountain and forest transportation involves unpredictable routes and small quantities per trip, it is difficult to deploy specialized equipment. During transportation, the ropes are prone to loosening due to road bumps, which can cause the pipes to slip and break.

[0014] Therefore, in view of the above-mentioned problems, the present invention provides an auxiliary device for oil pipeline transportation, with reference to... Figure 1-3 As shown, it includes a pipe body 1 and two conveying devices 2. The two conveying devices 2 are located directly below the pipe body 1. The symmetrical arrangement of the two conveying devices 2 can form a balanced support force from the bottom of the pipe body 1, effectively avoiding the tilting problem of the pipe body 1 that is easily caused by a single support point. The conveying device 2 includes a car body 21, which is located directly below the pipe body 1. A fixed cylinder 22 is fixedly connected to the upper surface of the car body 21. Two sliding columns 23 are slidably connected inside the fixed cylinder 22. The setting of the fixed cylinder 22 can facilitate the movement of the sliding columns 23, while restricting the position of the pad 24. A pad 24 is fixedly connected to the upper surface of the two sliding columns 23. The pad 24 is located at the bottom end of the tube body 1 and can support the tube body 1. Four buffers 25 are fixedly connected to the upper surface of the vehicle body 21. The buffers 25 are located directly below the pad 24. The four buffers 25 can simultaneously absorb road bumps or external impacts during transportation, significantly reducing the impact of vibration on the tube body 1. A pull rod 26 is fixedly connected to the side wall of the vehicle body 21. The pull rod 26 facilitates the operator to pull and push the device, improving the convenience of short-distance transportation within the site. An air bladder 27 is inserted inside the pad 24. The air bladder 27 can be inflated to further enhance the cushioning effect and can also fit the bottom curved surface of the tube body 1 to improve the support fit. A valve core 28 is fixedly connected to the side wall of the airbag 27. The valve core 28 is inserted into the inside of the pad 24. The valve core 28 facilitates the inflation and deflation adjustment of the airbag 27 to adapt to different vibration intensity scenarios or the support requirements of the tube 1. A wear-resistant plate 29 is fixedly connected to the upper surface of the airbag 27. The wear-resistant plate 29 is a polyurethane rubber sheet. The polyurethane rubber material has excellent wear resistance and toughness, which can reduce the frictional wear between the tube 1 and the airbag 27 to extend the life of the airbag 27.

[0015] refer to Figure 4-5 As shown, the upper surface of the pad 24 is provided with a limiting device. The setting of the limiting device can reduce the problem of displacement or even slippage of the pipe body 1 due to vibration and bumps during transportation. The limiting device includes two fixing blocks 31. The bottom ends of the two fixing blocks 31 are fixedly connected to the upper surface of the pad 24. The rigid fixing method can build a stable installation foundation for the entire limiting structure and reduce the failure of the limiting due to the loosening of the fixing blocks 31 during the limiting process. A rotating block 32 is rotatably connected to the surface of the fixed block 31. The rotating block 32 can rotate flexibly around the fixed block 31, so that the subsequent limiting component can adaptively adjust the angle according to the diameter of the tube body 1. A connecting block 33 is fixedly connected to the upper surface of the rotating block 32. An elastic band 34 is fixedly connected to the surfaces of the two connecting blocks 33. The elastic band 34 is located on the surface of the tube body 1. The elastic band 34, with its own elastic expansion and contraction properties, can closely fit the surface of the tube body 1 to form a continuous pre-tightening force, and achieve flexible limiting from above the tube body 1. A compression sleeve 35 is fixedly connected to the surface of the rotating block 32. The compression sleeve 35 is located on one side of the tube body 1. The compression sleeve 35 can form an auxiliary limit from the side of the tube body 1 and cooperate with the upper elastic band 34 to construct a multi-directional limit system. At the same time, the compression sleeve 35 is usually made of flexible and wear-resistant material, which can not only enhance the fit with the tube body 1, but also reduce the friction damage to the side of the tube body 1 during the limit process.

[0016] refer to Figure 6-8As shown, the side wall of the vehicle body 21 is provided with an auxiliary device 4. The auxiliary device 4 and the conveying device 2 form a cooperative support system, which effectively makes up for the problem of insufficient support strength of the single conveying device 2. The auxiliary device 4 includes a frame 401 located on the side wall of the vehicle body 21 and the bottom of the tube 1. The reasonable spatial layout can not only tightly connect the vehicle body 21 and the tube 1, but also provide a stable installation foundation for subsequent support components. Two sleeves 402 are fixedly connected to the upper surface of the frame 401. A sliding rod 403 is slidably connected inside the sleeve 402. The sliding fit design of the sleeve 402 and the sliding rod 403 allows the sliding rod 403 to be flexibly raised and lowered along the sleeve 402. A top plate 404 is fixedly connected to the upper surface of the two sliding rods 403. The top plate 404 is located directly below the tube body 1. The top plate 404 can form a multi-point uniform support with the pad 24 of the conveying device 2, further dispersing the pressure generated by the weight of the tube body 1. Two springs 405 are fixedly connected to the bottom end of the top plate 404 and the upper surface of the two sleeves 402. The springs 405 are sleeved on the surface of the sliding rods 403. The springs 405 can drive the sliding rods 403 to slide, and at the same time, they can also make the top plate 404 fit against the tank. A soft pad 406 is fixedly connected to the upper surface of the top plate 404. The soft pad 406 is made of flexible material, which can enhance the fit between the top plate 404 and the tube body 1, and can also avoid surface scratches caused by hard contact between the top plate 404 and the tube body 1. Multiple through holes 407 are opened on the surface of the frame 401. The opening of the through holes 407 can facilitate the installation of other equipment on the frame 401, such as installing a battery on the frame 401 to provide power to the vehicle body 21. A connecting plate 408 is fixedly connected to the side wall of the frame 401. A collar 409 is rotatably connected to the upper surface of the connecting plate 408. Part of the structure of the vehicle body 21 is inserted into the connecting plate 408 and the collar 409. A mounting bolt 410 is threadedly connected to the collar 409 and the inside of the vehicle body 21. By setting the connecting plate 408, the collar 409, and the mounting bolt 410, the frame 401 and the vehicle body 21 can be fixed together, and the frame 401 can also be rotated easily. A placement block 411 is fixedly connected to the surface of the sleeve 402. A threaded connection is made inside the placement block 411. The threaded post 413 and the slide rod 403 have a groove 412 on their surfaces. The side wall of the threaded post 413 is provided with a rubber post. The threaded post 413 is inserted into the groove 412. The engagement of the threaded post 413 and the groove 412 can lock and fix the adjusted position of the slide rod 403. The rubber post on the side wall of the threaded post 413 can increase the contact friction between the threaded post 413 and the groove 412, improve the locking stability, and avoid wear caused by direct collision between the metal threaded post 413 and the groove 412.

[0017] The working principle of this invention is as follows: Two conveying devices 2 are symmetrically arranged directly below the preset placement area of ​​the tube body 1 to be transported. The connection between the frame 401 and the body 21 is completed by the connecting plate 408 and the collar 409 of the auxiliary device 4. After the collar 409 is rotated to fit the side wall structure of the body 21, the mounting bolt 410 is tightened to achieve a stable fixation between the frame 401 and the body 21, so that the auxiliary device 4 and the conveying device 2 form a cooperative support unit. At the same time, auxiliary equipment such as batteries can be installed through the through holes 407 on the surface of the frame 401. Push the slide rod 403 to slide along the sleeve 402 to drive the top plate 404 to rise and fall. After the soft pad 406 on the top plate 404 is in contact with the bottom of the tube body 1, turn the threaded post 413 on the placement block 411 so that the end of the threaded post 413 with the rubber post is inserted into the corresponding slot 412 of the slide rod 403, locking the position of the slide rod 403. At this time, the pad 24 and the top plate 404 form a multi-point uniform support to distribute the weight of the tube body 1. Inflating the airbag 27 through the valve core 28 on the side wall of the pad 24 causes the airbag 27 to expand and fit tightly against the bottom curved surface of the tube body 1. At the same time, the polyurethane wear-resistant sheet 29 on the airbag 27 contacts the tube body 1. Rotating the rotating block 32 around the fixed block 31 causes the extrusion sleeve 35 on the rotating block 32 to fit against the side of the tube body 1. At the same time, the elastic band 34 is fixed to the two connecting blocks 33. The elastic band 34 undergoes elastic deformation due to the compression of the tube body 1, forming a continuous pre-tightening force from above the tube body 1. This, together with the extrusion sleeve 35, constructs a multi-directional limiting system. At this time, the four buffers 25 of the conveying device 2 and the spring 405 of the auxiliary device 4 are all in a pre-compressed state, providing shock absorption capabilities. The operator uses the pull rod 26 on the side wall of the vehicle body 21 to pull or push the tube body 1 to move. During transportation, the vibration caused by road bumps will be absorbed by the multiple shock absorption structure; the buffer 25 directly buffers the vibration transmitted from the pad 24, the airbag 27 further weakens the impact through its own elasticity, and the spring 405 absorbs the vibration transmitted from the top plate 404 through its extension and retraction; at the same time, the pre-tension of the elastic band 34 and the side limit of the compression sleeve 35 can effectively prevent the tube body 1 from shifting longitudinally or laterally due to vibration, and the wear-resistant plate 29 and the soft pad 406 prevent the surface of the tube body 1 from being scratched by friction.
