Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oilfield anti-pressure pipeline connection, and particularly relates to a quick connection structure for anti-pressure pipelines in oilfield development. Background Technique
[0002] Oilfield anti-pressure pipelines refer to pipelines used for transporting fluids such as oil and natural gas, ensuring safe and effective transportation under high-pressure environments. They have high anti-pressure capabilities during use to cope with extreme pressure conditions that may be encountered in oilfield operations. When docking and installing oilfield anti-pressure pipelines, corresponding docking mechanisms are required for assembly and connection;
[0003] For example, the patent with the publication number CN214534972U discloses a pipeline sealing connection structure for oilfield oil production. The materials of the first pipeline and the second pipeline from the inside to the outside are Rausling synthetic stone layer, insulation layer, stainless steel layer, and anti-corrosion coating layer, which play roles such as high-temperature resistance, anti-static, heat preservation, firmness, and anti-corrosion respectively. There are threads on the inner circle of the iron sheet, which can be rotated and fixed to the pipeline. The other side of the iron sheet is connected to the third cushion layer, and then fixed to the second flange through screws, which can make the connection more sealed. Hinges are fixedly installed at both ends of the iron sheet and the second flange, and a lock can be added between the two hinges, which can only be opened with a key. Otherwise, any other way of unlocking will transmit this information to the sensor and alarm, playing a role in anti-theft. A valve is fixedly installed on the upper part of the connector body. To open the valve, the correct password needs to be entered on the control panel first, which not only helps to sample the produced oil but also prevents oil theft;

Specific embodiments
[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Please refer to Figures 1-8 , the present utility model provides the following technical solutions.
[0033] Embodiment 1: To solve the problem that in the prior art, most connections and fixings are carried out by screws, which are prone to looseness during long-term use and have poor fastening performance. Therefore, in this embodiment, through the following technical solutions, a quick-connection structure for an anti-pressure pipeline in oilfield development is provided, which is provided with an anti-pressure pipeline body 1, an installation cylinder 2, a sealing ring 3, an installation rod 4, a first installation cap 5 and a second installation cap 6. The anti-pressure pipeline body 1 is respectively inserted into the left and right ends of the installation cylinder 2, and a sealing ring 3 is fitted at the connection between the installation cylinder 2 and the anti-pressure pipeline body 1. The installation rods 4 are respectively inserted into the edges of the anti-pressure pipeline body 1 and the installation cylinder 2, and the installation rods 4, the first installation cap 5 and the second installation cap 6 are arranged at equal angles on the outside of the installation cylinder 2. The first installation cap 5 and the second installation cap 6 are both threadedly connected to the left and right sides of the installation rod 4, and the first installation cap 5 and the second installation cap 6 are symmetrically arranged on the left and right sides of the installation rod 4. The first installation cap 5 and the second installation cap 6 are in contact with each other, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the anti-pressure pipeline body 1 is respectively inserted into the left and right ends of the installation cylinder 2, and the combined sealing ring 3 is arranged in a fitting manner between the anti-pressure pipeline body 1 and the installation cylinder 2, which improves the sealing effect at the connection and prevents leakage. Then, the installation rods 4 are respectively inserted into the edge positions at the connection of the anti-pressure pipeline body 1 and the installation cylinder 2, and the first installation cap 5 and the second installation cap 6 are respectively threadedly arranged at the left and right ends of the installation rod 4. Considering the tight fit between the first installation cap 5 and the installation cylinder 2, as well as the tight fit between the first installation cap 5 and the second installation cap 6, the stability and tightness of the connection among the installation rod 4, the installation cylinder 2, and the anti-pressure pipeline body 1 are improved, preventing loosening during long-term use.
[0034] Embodiment 2: In the existing quick-connection structure of anti-pressure pipelines for oilfield development, it is inconvenient to stably support the pipeline during actual docking. Therefore, by setting the support columns 7, the bearing frame 8, the support plate 9, and the fixing bolts 10, a sliding structure is formed between the support column 7 and the bearing frame 8, and the support column 7 and the support plate 9 are limited by the fixing bolts 10. Both the fixing bolt 10 and the support column 7 and the fixing bolt 10 and the support plate 9 are in threaded connection, and side plates 11 are fixedly connected to both the left and right ends of the support plate 9. The support columns 7 are respectively fixedly connected to the front and rear ends of the installation cylinder 2, and the support column 7 is inserted into the middle of the support plate 9. As Figure 1 、 Figure 5 and Figure 7 shown, the lower end of the bearing frame 8 is fixedly removed and fixed at the corresponding support position, the support column 7 is connected to the bearing frame 8 through a slot, and at the same time, the support column 7 is inserted into the middle of the support plate 9. Then, the fixing bolt 10 is rotated to limit the support column 7 and the support plate 9 through the fixing bolt 10, thereby facilitating the stable support of the anti-pressure pipeline body 1.
[0035] Embodiment 3: In the existing quick-connection structure of anti-pressure pipelines for oilfield development, it is inconvenient to adjust the actual installation and docking height according to the actual situation. Therefore, by setting the side plates 11, the fixing plates 12, the fixing grooves 13, and the fixing mechanism 14, fixing plates 12 are fixedly connected to both the left and right ends of the outer side surface of the bearing frame 8, and fixing grooves 13 with a limiting function are equally spaced on the inner side of the fixing plates 12. The fixing mechanism 14 includes movable plates 15 sleeved on both the left and right ends of the support plate 9, springs 16 arranged between the movable plates 15 and the side plates 11, limit blocks 17 fixedly connected to both the upper and lower ends of the support plate 9, and fixing pins 18 fixedly connected to the side surfaces of the movable plates 15. Moreover, a left-right sliding structure is formed between the movable plates 15 and the limit blocks 17, and the movable plates 15 drive the fixing pins 18 to be inserted into the fixing grooves 13 at the corresponding positions. As Figure 5 、 Figure 6 and Figure 8As shown, by pulling the movable plate 15, the movable plate 15 slides between the limit blocks 17. At this time, the movable plate 15 squeezes the spring 16, causing the spring 16 to undergo elastic deformation. At this time, the movable plate 15 drives the fixing pin 18 to move out of the fixing groove 13, thereby releasing the limit between the support plate 9 and the carrier 8. Then, according to the actual support requirement, pull the support plate 9. The support plate 9 drives the sliding between the support column 7 and the carrier 8, thereby driving the lifting of the anti-pressure pipeline body 1 and adjusting the support height of the anti-pressure pipeline body 1. When adjusted to the corresponding height, directly release the movable plate 15. At this time, the spring 16 restores elastic deformation, driving the sliding between the movable plate 15 and the limit block 17, so that the movable plate 15 drives the fixing pin 18 to be inserted into the fixing groove 13 at the corresponding position, thereby facilitating the limitation between the support column 7 and the carrier 8 and improving the stability during the support process.
[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
