Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil pipeline equipment technology, and in particular to an oil tapping pipeline for petrochemical applications. Background Technology
[0002] When performing multi-point sampling, testing, or branching operations in existing petrochemical plants, it is often necessary to temporarily weld branch pipes onto the main pipeline or use on-site drilling methods. This results in long construction cycles, high safety risks, and irreversible damage to the pipeline itself. At the same time, once the branch pipe is fixed, it is difficult to adjust its position or height according to changes in operating conditions, which brings great inconvenience to later maintenance, repair, and process adjustments.
[0003] Traditional supports are mostly integral welded structures, lacking sliding connections between horizontal and vertical beams. This makes them unsuitable for accommodating oil pipes of varying diameters and densities, requiring extensive cutting and secondary welding during on-site installation, resulting in high labor intensity and significant cumulative errors. Furthermore, existing clamps are typically secured to the supports using spot welding or bolts, which can lead to stress concentration when the oil pipes expand due to heat or vibrate, causing seal failure or even breakage. The supports themselves lack independent locking and limiting mechanisms, making them prone to lateral slippage under wind loads or external forces, affecting system stability. While some modular supports have emerged to overcome these shortcomings, they still use fixed hole connections between the horizontal and vertical frames, limiting the range of slip adjustment and failing to fully consider the need for parallel, layered oil pipe arrangements. This hinders the rapid assembly and precise positioning of multiple layers and multiple oil pipes in vertical space, restricting the development of petrochemical plants towards intensification and standardization. Utility Model Content
[0004] In view of this, the technical problem to be solved by this utility model is: how to provide a branch pipe that is suitable for different oil pipe layer layouts and can be flexibly adjusted in installation and positioning.
[0005] To achieve the above objectives, this utility model proposes a petroleum tapping pipeline for petrochemical applications, which includes a first oil pipe, a second oil pipe, a vertical frame, a horizontal frame, a connecting frame, a lock cover, a support rod, and a clamp.
[0006] The uprights are arranged vertically, and multiple uprights are spaced apart along the length. Adjacent uprights are connected by horizontal frames. The two ends of the horizontal frames are fixedly connected to the uprights. The horizontal frames are respectively connected to the bottom and top of the uprights, and the horizontal frames are provided with sliding grooves.
[0007] The two ends of the connecting frame are respectively connected to the horizontal frame arranged in parallel. The connecting frame is provided with mounting slots, and multiple mounting slots are spaced apart along the length of the connecting frame. The support rod is connected to the mounting slot, and the clamp is connected to the support rod.
[0008] The first oil pipe and the second oil pipe are respectively connected to the clamp, and the first oil pipe and the second oil pipe are arranged in parallel in the height direction;
[0009] The lock cover includes a connecting plate and a mounting plate. The connecting plate is located on both sides of the mounting plate. The mounting plate is connected to the connecting frame. Connecting fasteners are passed through the connecting plate and the fasteners pass through the sliding groove.
[0010] Furthermore, the mounting plate is provided with fastening holes, which correspond to the mounting groove. The fastening holes are used to install fasteners, and the fasteners can be accommodated in the mounting groove to restrict the movement of the connecting frame.
[0011] Furthermore, the connecting plate is attached to the top surface of the crossbeam.
[0012] Furthermore, the support rod is fixedly connected to the mounting groove by fasteners.
[0013] Compared with related technologies, the petroleum tapping pipeline for petrochemical industry proposed in this utility model has the following advantages:
[0014] This technical solution achieves rapid assembly and multi-dimensional adjustment of oil tapping pipelines through modular combination of uprights, horizontal frames, connecting frames, chutes, and installation slots. It avoids permanent damage to the main pipeline caused by on-site welding or drilling, significantly shortens the construction cycle, and reduces safety risks. The double-layer arrangement of the horizontal frames and the sliding cooperation of the connecting frames allow the first and second oil pipes to be fixed in parallel and layered in the vertical space, meeting the flexible adjustment requirements for pipe diameter, spacing, and height under different working conditions, and improving the system's space utilization and compatibility.
[0015] The fastener connection between the support rod and the mounting groove and clamp provides a rigid positioning that can be repeatedly disassembled and assembled. Combined with the elastic clamping of the clamp, it suppresses stress concentration caused by thermal expansion and contraction of the oil pipe, reduces vibration transmission, and extends the seal life. The locking cover's connecting plate straddles the top surface of the crossbeam and limits lateral displacement through a sliding groove. The mounting plate is locked in place with the fastening holes and mounting groove, forming a double limit to prevent the connecting frame from sliding under external forces or wind loads, enhancing overall stability. All components use standardized profiles and universal fasteners, allowing for batch assembly without secondary processing on-site, reducing manufacturing and maintenance costs, and promoting the development of petrochemical pipeline systems towards intensification and standardization.

[0017] Figure 2 This is a partial structural diagram of a petroleum tapping pipeline for petrochemical applications, as described in an embodiment of this utility model. Detailed Implementation
[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0019] Please see Figure 1 - Figure 2 As shown, this utility model proposes a petroleum branch pipe for petrochemical use, which includes a first oil pipe 11, a second oil pipe 12, a vertical frame 21, a horizontal frame 22, a connecting frame 23, a lock cover 24, a support rod 25, a clamp 26, a connecting plate 241, and a mounting plate 242.
[0020] The uprights 21 are arranged vertically, and multiple uprights 21 are arranged at intervals along the length direction. The adjacent uprights 21 are connected by horizontal frames 22. The two ends of the horizontal frames 22 are fixedly connected to the uprights 21. The horizontal frames 22 are respectively connected to the bottom and top of the uprights 21, and the horizontal frames 22 are provided with sliding grooves.
[0021] The uprights 21 are set vertically and spaced apart along the length. As the basic support component of the overall structure, they provide installation base points for the crossbeams 22. Through the fixed connection with the crossbeams 22, a stable frame system is formed to ensure that the entire pipeline support structure has sufficient vertical bearing capacity to cope with the weight of the oil pipeline and the external forces during operation.
[0022] The horizontal frame 22 is connected to the lower and upper parts of the adjacent vertical frame 21, and its two ends are fixed to the vertical frame 21. It not only further strengthens the connection stability between the vertical frames 21, making the spaced vertical frames 21 form an integral load-bearing structure, but also the sliding groove on the horizontal frame 22 provides an adjustable installation path for the installation of the connecting frame 23. Through cooperation with the locking cover 24, the position of the connecting frame 23 in the length direction of the horizontal frame 22 can be adjusted, thereby meeting the installation requirements of oil pipelines of different lengths and specifications.
[0023] The connecting frame 23 is connected to the parallel crossbeam 22 at both ends. The mounting groove on it is used to install the support rod 25. Through the cooperation between the mounting groove and the support rod 25, the installation position of the support rod 25 can be adjusted according to the pipeline layout requirements, thereby achieving precise positioning of the first oil pipe 11 and the second oil pipe 12.
[0024] Meanwhile, the connecting frame 23 is fixed to the cross frame 22 by the locking cover 24, and the fastening holes on the mounting plate 242 correspond to the mounting groove. The movement of the connecting frame 23 is restricted by the fasteners, which ensures the structural stability of the connecting frame 23 when carrying the pipeline, and finally achieves reliable support for the first oil pipe 11 and the second oil pipe 12 to be set in parallel in the height direction.
[0025] The two ends of the connecting frame 23 are respectively connected to the horizontal frame 22 arranged in parallel. The connecting frame 23 is provided with mounting slots. Multiple mounting slots are spaced apart along the length of the connecting frame 23. The support rod 25 is connected to the mounting slot. The support rod 25 is fixedly connected to the mounting slot by fasteners. The clamp 26 is connected to the support rod 25.
[0026] The first oil pipe 11 and the second oil pipe 12 are respectively connected to the clamp 26, and the first oil pipe 11 and the second oil pipe 12 are arranged in parallel in the height direction.
[0027] The lock cover 24 includes a connecting plate 241 and a mounting plate 242. The connecting plate 241 is located on both sides of the mounting plate 242. The mounting plate 242 is connected to the connecting frame 23. Connecting fasteners are passed through the connecting plate 241 and the fasteners pass through the sliding groove. The connecting plate 241 is attached to the top surface of the cross frame 22.
[0028] The mounting plate 242 is provided with fastening holes, which correspond to the mounting grooves. Fasteners are installed in the fastening holes and can be accommodated in the mounting grooves to restrict the movement of the connecting bracket 23.
[0029] The locking cover 24 includes a connecting plate 241 and a mounting plate 242. The connecting plate 241 is located on both sides of the mounting plate 242. Its purpose is to achieve adjustable fixation between the connecting frame 23 and the cross frame 22, while ensuring the structural stability of the connecting frame 23 when carrying the pipeline.
[0030] The connecting plate 241 is attached to the top surface of the cross frame 22, and the fasteners on it are inserted into the sliding groove of the cross frame 22. Through the cooperation of the fasteners and the sliding groove, the connecting frame 23 can be adjusted in position along the length of the cross frame 22 to adapt to the installation requirements of oil pipelines of different lengths.
[0031] The mounting plate 242 is connected to the connecting bracket 23. The fastening holes on the plate correspond to the mounting grooves of the connecting bracket 23. The fasteners installed in the fastening holes can be accommodated in the mounting grooves, thereby restricting the movement of the connecting bracket 23 and ensuring that the connecting bracket 23 will not shift its position due to external forces during pipeline operation.
[0032] Through the above-mentioned structural design of the locking cover 24, the connecting frame 23 can be flexibly adjusted on the cross frame 22, and it can be firmly fixed after adjustment. This ensures that the support frame composed of the upright frame 21, the cross frame 22, and the connecting frame 23 can stably support the first oil pipe 11 and the second oil pipe 12, thus ensuring the safe operation of the oil distribution pipeline.
[0033] The support rod 25 is connected to the mounting slot of the connecting frame 23 and fixed by fasteners. Its purpose is to provide a stable mounting carrier for the clamp 26. At the same time, it can adjust its own installation position by selecting different mounting slots according to the pipeline layout requirements, so as to adapt to the specific installation spacing requirements of the first oil pipe 11 and the second oil pipe 12.
[0034] The clamp 26 is connected to the support rod 25 and is used to directly connect and fix the first oil pipe 11 and the second oil pipe 12 to ensure that the oil pipes do not shake or shift during operation.
[0035] The support rod 25 is adjustable in position by cooperating with the mounting groove, so that the position of the clamp 26 can be adjusted accordingly, thereby meeting the installation requirements of oil pipes of different specifications and enhancing the applicability of the overall structure.
[0036] The clamp 26 is in direct contact with the oil pipe. Its structural design allows it to fit tightly against the outer wall of the oil pipe, transmitting the force on the oil pipe to the support rod 25. The force is then transmitted through the support rod 25 to the connecting frame 23 and the entire support frame, ensuring the stability of the first oil pipe 11 and the second oil pipe 12 in parallel in the height direction. This prevents the oil pipe from shaking or shifting, which could affect the safety and reliability of the oil pipe connection process, and thus ensures the normal operation of the entire petrochemical oil pipe connection pipeline.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
