Technical Field
[0001] This utility model relates to the field of fence technology, and in particular to an adjustable metal protective fence for petrochemical equipment. Background Technology
[0002] A fence is a device that uses physical barriers to achieve spatial isolation, security protection, or area demarcation. Its core function is to restrict the passage of personnel, animals, or objects while providing clear spatial boundary markings. Among them, the metal protective fence for petrochemical equipment is a physical isolation device specifically designed for the petrochemical industry. Its core function is to provide safety protection for critical facilities such as equipment, pipelines, and storage tanks in petrochemical production through a continuous barrier formed by a metal structure, preventing personnel from accidentally entering dangerous areas, avoiding accidental equipment collisions or external interference, and meeting the special environmental requirements of the petrochemical industry for corrosion resistance, impact resistance, and explosion protection.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Current petrochemical equipment protective fences mostly adopt a fixed length design, which cannot be flexibly adjusted according to the dynamic changes of equipment maintenance areas or work spaces. Traditional fences achieve length extension by segment splicing or bolt fixing, but the splicing process depends on tools and is time-consuming. Especially in high-temperature, high-pressure or flammable and explosive petrochemical environments, frequent disassembly and assembly can easily cause safety hazards. In addition, when dealing with non-standard equipment layouts, fixed fences often result in excessive protective gaps due to length mismatch, which cannot effectively isolate personnel from dangerous areas and pose safety risks. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that the existing petrochemical equipment protective fences mostly adopt a fixed length design. To address this, we propose an adjustable metal protective fence for petrochemical equipment.
[0005] To achieve the above objectives, this application adopts the following technical solution: an adjustable metal protective fence for petrochemical equipment, comprising an outer fence: an inner fence is slidably connected to the inner fence, and a post is fixedly connected to one side of the outer fence and one side of the inner fence. Two circular grooves are opened at both ends of the outer fence on the side away from the post, and a movable rod is slidably connected to the inner groove. A pull plate is fixedly connected to the end of the movable rod away from the circular groove, and a fixing block is fixedly connected to one end of the pull plate. Several fixing grooves are opened at both ends of the inner fence, and one end of the fixing block is slidably connected to the inner groove.
[0006] Preferably, an elastic sleeve is fixedly connected to the surface of the fixing block near the fixing groove, and the surface of the elastic sleeve is inserted into the interior of the fixing groove.
[0007] Preferably, the top and bottom of the outer fence are provided with T-shaped grooves, and the top and bottom of one side of the inner fence are fixedly connected with T-shaped sliders, the surface of the T-shaped sliders being slidably connected to the inside of the T-shaped grooves.
[0008] Preferably, a plurality of ball bearings are installed at both the top and bottom of the inner side of the outer fence, and the ball bearings are distributed at both ends of the elastic sleeve.
[0009] Preferably, a spring is slidably connected to the surface of the movable rod, one end of the spring is fixedly connected to one end inside the circular groove, and the other end of the spring is fixedly connected to one end of the movable rod.
[0010] Preferably, the top and bottom of the movable rod are provided with limit grooves, and the top and bottom of the circular groove near the pull plate are fixedly connected with limit blocks, and the surface of the limit block is slidably connected to the inside of the limit groove.
[0011] Preferably, the bottom of the column is provided with a threaded groove, and the threaded groove is internally connected to a threaded support foot.
[0012] The technical effects and advantages of this utility model are as follows: In this invention, by pulling the pull plates at both ends of the outer fence, the pull plates cause the fixing blocks to move out of the fixing groove. At this time, the limiting position of the inner fence inside the outer fence is released. Workers can move the inner fence out of the outer fence according to the needs of the existing site, thereby adjusting the total length of the guardrail. After adjustment, the pull plates are released, and the elasticity of the spring causes the pull plates to reset, thereby achieving automatic reset of the fixing blocks. One end of the fixing block enters the fixing groove. By setting an elastic sleeve on the surface of the fixing block, the elasticity of the elastic sleeve can fill the gap between the fixing block and the fixing groove, making the connection between the fixing block and the fixing groove tighter and preventing the fixing block from loosening from the inside of the fixing groove. By allowing the inner fence to be pulled out from the inside of the outer fence, the fence length can be quickly adjusted without tools to adapt to different equipment sizes and changes in working space, significantly improving on-site layout efficiency.

Specifically: By pulling the pull plates 6 at both ends of the outer fence 1, the pull plates 6 move the fixing blocks 7 out of the fixing groove 8. At this time, the limit of the inner fence 2 inside the outer fence 1 is released. The staff can move the inner fence 2 out of the outer fence 1 according to the needs of the existing site, thereby adjusting the total length of the guardrail. After the adjustment is completed, the pull plate 6 is released. The elasticity of the spring 12 drives the pull plate 6 to reset, thereby achieving the automatic reset of the fixing block 7. One end of the fixing block 7 enters the fixing groove 8. By setting the elastic sleeve 9 on the surface of the fixing block 7, the elasticity of the elastic sleeve 9 can fill the gap between the fixing block 7 and the fixing groove 8, making the connection between the fixing block 7 and the fixing groove 8 tighter and preventing the fixing block 7 from coming loose from the fixing groove 8.

[0018] Working principle: By pulling the pull plates 6 at both ends of the outer fence 1, the pull plates 6 move the fixing blocks 7 out of the fixing grooves 8. At this time, the limit of the inner fence 2 inside the outer fence 1 is released. Workers can move the inner fence 2 out of the outer fence 1 according to the needs of the existing site, thereby adjusting the total length of the guardrail. After the adjustment is completed, the pull plates 6 are released. The elasticity of the spring 12 drives the pull plates 6 to reset, thereby achieving the automatic reset of the fixing blocks 7. One end of the fixing blocks 7 enters the fixing groove 8. By setting the elastic sleeve 9 on the surface of the fixing blocks 7, the elasticity of the elastic sleeve 9 can fill the gap between the fixing blocks 7 and the fixing groove 8, making the connection between the fixing blocks 7 and the fixing groove 8 tighter and preventing the fixing blocks 7 from loosening from the fixing groove 8. By allowing the T-shaped slider 10 to slide inside the T-shaped groove 17, the movement position of the inner fence 2 inside the outer fence 1 can be restricted, making the movement of the inner fence 2 more stable and preventing deviation. By setting the ball bearing 11, the friction generated when the inner fence 2 moves inside the outer fence 1 can be reduced, making the movement of the inner fence 2 smoother. By allowing the limiting block 14 to slide inside the limiting groove 13, the movement position of the pull plate 6 can be restricted, allowing the pull plate 6 to drive the fixing block 7 to accurately enter the interior of the fixing groove 8. By connecting the threaded support foot 16 to the bottom of the column 3, the user can adjust the height of the column 3 by rotating the threaded support foot 16 so that one end of the threaded support foot 16 is turned out from the internal thread of the threaded groove 15, thereby adjusting the total height of the fence.
