Description
Technical Field
[0001] This utility model belongs to the field of methanol fuel pipeline technology, and in particular relates to a safe connection structure for methanol fuel pipelines. Background Technology
[0002] With the accelerated development of the clean energy industry, methanol fuel, with its advantages of wide availability, high combustion efficiency, and low carbon emissions, is increasingly being used in industrial production, transportation, and other fields, and market demand continues to grow. In the storage and transportation system of methanol fuel, the pipeline connection structure is the core component that ensures stable fuel transmission. Its sealing performance, compressive strength, and corrosion resistance directly determine the safety and reliability of the methanol fuel transportation process. Therefore, a high-performance methanol fuel pipeline safety connection structure is needed to achieve effective docking between pipelines.
[0003] However, the existing connection structure is complicated and cumbersome to install, which makes subsequent inspection, maintenance or disassembly more difficult. When the connection structure needs to be adjusted or replaced, more effort is required to disassemble and reassemble, reducing the overall construction efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a safe connection structure for methanol fuel pipelines. By setting up an installation part, it solves the problem that the existing connection structure is complicated and cumbersome to install, which increases the difficulty of subsequent inspection, maintenance or disassembly. When the connection structure needs to be adjusted or replaced, more effort is required to disassemble and reassemble, which reduces the overall construction efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a safe connection structure for a methanol fuel pipeline, comprising two pipelines and: a connecting part installed on the two pipelines; several mounting parts, each mounted on the connecting part; several fastening parts, each mounted on one of the mounting parts; each mounting part includes a support assembly installed on the pipeline; and a fixing assembly installed on the support assembly. The support assembly includes a hollow rod installed on the pipeline, with a spring telescopic rod fixedly connected to the inner right side of the hollow rod, and a support rod fixedly connected to the left side of the spring telescopic rod. The left side of the support rod extends beyond the hollow rod, and the support rod is connected to the hollow rod... The support rod is slidably connected, and a circular ring is slidably connected to the outer wall of the support rod. The circular ring is fixedly connected to the inner wall of the hollow rod. The support rod is provided with hinges. There are seven mounting parts and seven fastening parts, arranged in a circumferential array. The hinges include several rectangular slots opened on the hollow rod. Several hinge blocks are fixedly connected to the right side of the circular ring. Each of the hinge blocks is hinged with an H-shaped hinge rod. Several hinge blocks are fixedly connected to the outer wall of the support rod. Each of the hinge blocks is hinged with a fixed rod. The H-shaped hinge rods are respectively hinged to several fixed rods. There are four rectangular slots, four hinge blocks, and four hinge blocks, arranged in a circumferential array. This is the core mechanical structure for achieving rapid installation.
[0006] Furthermore, the connection part includes connecting flanges that are fixedly connected to the two pipes on their respective sides close to each other. Each of the two connecting flanges has several mounting holes, and a sealing ring is provided between the two connecting flanges.
[0007] Furthermore, the fastening part includes an elastic component mounted on the support component; and a fastening component mounted on the elastic component.
[0008] Furthermore, the fixing component includes a threaded groove on the outer wall of the hollow rod, and a nut is fitted on the outer wall of the hollow rod; the nut is threadedly connected to the hollow rod through the threaded groove, forming an "inner and outer clamping" effect with the fixing rod of the support component.
[0009] Furthermore, the elastic component includes a cylindrical cover fixedly connected to the left side of the hollow rod. The cylindrical cover is slidably connected to the outer wall of the support rod. A threaded groove is provided inside the cylindrical cover, and an elastic element is provided inside the cylindrical cover. The cylindrical cover is penetrated by the support rod and slidably connected. The elastic element includes a plurality of elastic fixing blocks fixedly connected to the inner wall of the right side of the cylindrical cover. There are six elastic fixing blocks arranged in a circumferential array to ensure the fixing effect and to adapt to slight deformation.
[0010] Furthermore, the fastening assembly includes a threaded ring disposed on the left side of the cylindrical cover, the threaded ring being adapted to the second threaded groove, and a handle being fixedly connected to the left side of the threaded ring; the threaded ring is threadedly connected to the inner wall of the cylindrical cover through the second threaded groove, realizing the human-machine interaction and power transmission component for fastening operation.
[0011] This utility model has the following beneficial effects: 1. By setting up the installation part, pressing the support rod causes it to slide on the circular ring and hollow rod, compressing the spring telescopic rod to generate elastic force. At the same time, the fixed rod moves through the second hinge block. Under the action of the H-shaped hinge rod, the fixed rod retracts into the hollow rod through the rectangular groove. After inserting the hollow rod into the mounting hole of the connecting flange, the support rod is released. The elastic force of the spring telescopic rod pushes the support rod back to its original position, so that the fixed rod contacts the outer wall of the connecting flange. Finally, the nut is rotated so that it moves along the threaded groove on the hollow rod and fits against the outer wall of the connecting flange. The two connecting flanges are fixed by the cooperation of the nut and the fixed rod. No complicated tools or cumbersome procedures are required, which reduces the difficulty of operation, facilitates quick installation, and reduces the complexity of subsequent operations. 2. By setting a fastening part, the threaded ring is rotated by turning the handle. The threaded ring moves into the cylindrical cover while rotating on the cylindrical cover, using the second threaded groove on the cylindrical cover. During the movement, the threaded ring exerts a squeezing effect on multiple elastic fixing blocks, causing these elastic fixing blocks to deform and generate elastic force. Finally, the support rod is fixed by the deformed elastic fixing blocks, which effectively prevents the support rod from shifting or shaking during use, ensures the positional stability of the support rod, lowers the operation threshold, and facilitates quick completion of the fixing operation.
