Description

Technical Field

[0001] The utility model belongs to the technical field of oil well enclosure protection structures, and particularly relates to a workover safety enclosure structure. Background Technique

[0002] During oilfield workover operations, an enclosure protection structure is generally set up. The oil well enclosure structure plays a crucial role in the process of oil extraction. It is mainly used for protecting the oil well area, safety warning and isolation, preventing unauthorized personnel from entering, ensuring the safety of oil well equipment and personnel, and also helping to prevent environmental pollution. In order to prevent the erosion of oil well facilities by external factors such as strong winds, heavy rains, sandstorms, oil stains, and groundwater, waterproof coiled materials are also arranged on the enclosure to ensure that the oil well facilities can still remain dry in humid or rainy environments and avoid equipment damage or safety hazards caused by moisture erosion.

[0003] When the enclosure protection frame is used and the waterproof coiled material is arranged on it, the waterproof coiled material is surrounded outside the enclosure protection frame. However, the waterproof coiled material is relatively soft and prone to wrinkles, which is not conducive to flat laying and firm fixation. In addition, the waterproof coiled material is generally firmly fixed by glue bonding or fasteners (such as screws). When the waterproof coiled material is aged and damaged, it is inconvenient to replace. When the enclosure protection frame is used, there is a problem that there is no design for facilitating the installation of the waterproof coiled material. For this reason, this application proposes a workover safety enclosure structure. Summary of the Utility Model

[0026] Embodiment

[0027] Please refer to Figures 1 to 6, the present utility model provides a technical solution: a workover safety enclosure structure, including a fence frame, which includes a fixed outer frame 11 and an enclosure net frame 12 installed inside the fixed outer frame 11. The fixed outer frame 11 and the enclosure net frame 12 are combined by conventional methods (such as welding). The fence frame plays a role in safety protection and warning of workover equipment; a waterproof coil, which includes a coil fabric 22, a first end rod 21 and a second end rod 23 respectively installed on both sides of the coil fabric 22. The coil fabric 22 and the first end rod 21 and the second end rod 23 are combined by conventional methods (such as bonding with strong glue). The waterproof coil is arranged on the surface of the enclosure net frame 12. The waterproof coil and the fence frame play a role in reducing the impact and damage of external factors on oilfield workover facilities; a stabilizing pipe 3, inside which there is a first flattening cylinder 31 and a guiding member. The stabilizing pipe 3 is combined with the fixed outer frame 11 by conventional means (such as welding). The first flattening cylinder 31 is connected to the stabilizing pipe 3 by screw threading. When the waterproof coil is laid, the coil fabric 22 passes through the stabilizing pipe 3. The first flattening cylinder 31 plays a role in guiding and flattening the coil fabric 22. The guiding member includes a second flattening cylinder 32 parallel to the first flattening cylinder 31, a stabilizing column 33 penetrating the end of the second flattening cylinder 32, and a compression spring 34 sleeved on the outer side of one end of the stabilizing column 33. The stabilizing column 33 is connected to the stabilizing pipe 3 by screw threading. The second flattening cylinder 32 is slidably connected to the stabilizing column 33. When the second flattening cylinder 32 slides, it squeezes the compression spring 34. Under the action of the resilience of the compression spring 34, the position of the second flattening cylinder 32 can be changed, so that the coil fabric 22 can bypass the second flattening cylinder 32 and thus be in a flat state; a pressing mechanism, which includes a fixing plate 41 installed on the fixed outer frame 11, a moving plate 42 slidably connected to the fixing plate 41, and a rolling member installed on the moving plate 42. The fixing plate 41 is connected to the fixed outer frame 11 by screw threading. The moving plate 42 can move along the length direction of the fixing plate 41, thereby changing the position of the rolling cylinder 54. The rolling member includes a handle 51 that fits the surface of the moving plate 42, a pull rod 52 penetrating the moving plate 42 and connected to the handle 51 at one end, a connecting plate 53 connected to the other end of the pull rod 52, a rolling cylinder 54 installed between the opposite surfaces of the connecting plate 53, and a compression spring 55 sleeved on the outer side of the pull rod 52. Pull the handle 51 outward, the handle 51 pulls the pull rod 52, the connecting plate 53 and the rolling cylinder 54, increasing the distance between the rolling cylinder 54 and the enclosure net frame 12, which is beneficial for the second end rod 23 and the coil fabric 22 to pass through. During the laying and stretching process of the coil fabric 22, the rolling cylinder 54 presses the coil fabric 22, which can limit its position and prevent it from sagging and forming wrinkles. Moreover, the rolling cylinder 54 also plays a role in flattening the coil fabric 22.

[0028] In this embodiment, a limiting groove a and a guiding groove b are formed on the outer surface of the stabilizing pipe 3. The limiting groove a and the guiding groove b are connected. The first flat cylinder 31 and the second flat cylinder 32 are located inside the guiding groove b. A protrusion 35 is provided on the inner side wall of the stabilizing pipe 3 where the limiting groove a is located. The protrusion 35 is of a semi-cylindrical structure, and the outer surface of the protrusion 35 is smooth. The coil fabric 22 bypasses the protrusion 35, which can flatten the coil fabric 22. The distance between the protrusion 35 and the inner side wall of the stabilizing pipe 3 is the spacing H. The outer diameter of the first end rod 21 is 3 mm larger than the spacing H, and the outer diameter of the second end rod 23 is 2 mm smaller than the spacing H, which is beneficial for the second end rod 23 and the coil fabric 22 to pass through the limiting groove a, and at the same time, the first end rod 21 is limited.

[0029] In this embodiment, a limiting cylinder 321 is provided on the outer side of the end of the second flat cylinder 32 close to the stabilizing column 33. The stabilizing column 33 is perpendicular to the inner side wall of the stabilizing pipe 3. One end of the stabilizing column 33 close to the compression spring 34 is of a "T" - shaped structure. Rubber ropes 221 are arranged inside the two edge positions of both sides of the coil fabric 22. One edge of the coil fabric 22 with the rubber ropes 221 is circular. The side of the circular edge of the coil fabric 22 bypasses the gap between the limiting cylinder 321 and the inner wall of the stabilizing pipe 3. The side of the coil fabric 22 is limited by the limiting cylinder 321, which can prevent the side of the stretched coil fabric 22 from sagging, facilitating its unfolding.

[0030] In this embodiment, the cross - section of the fixing plate 41 is of an "L" - shaped structure. A guide rail 411 and a slider 412 sliding along the length direction of the guide rail 411 are provided on the inner surface of the fixing plate 41. The guide rail 411 is connected to the fixing plate 41 by screw screwing. The top of the moving plate 42 is perpendicular to the slider 412, and the slider 412 is firmly connected to the moving plate 42 by screws, which can conveniently change the positions of the slider 412 and the moving plate 42. The outer surface of the rolling cylinder 54 is tangent to the surface of the opposing enclosure net frame 12. The coil fabric 22 passes through the space between the rolling cylinder 54 and the enclosure net frame 12. The rolling cylinder 54 can not only press the coil fabric 22 to prevent it from sagging, but also play a role in flattening the coil fabric 22 during the stretching process of the coil fabric 22.

[0031] The working principle and usage process of the present utility model:

[0032] The enclosure protection frame has a design facilitating the installation of the waterproof coil. When installing the waterproof coil,

[0033] The coil fabric 22 of the waterproof coil and the second end rod 23 pass through the limiting groove a of the stabilizing pipe 3;

[0034] Then, the coil fabric 22 and the second end rod 23 are first bypassed around the first flat cylinder 31;

[0035] Meanwhile, pull the second flattening cylinder 32. The second flattening cylinder 32 compresses the compression spring 34. There is a gap between the second flattening cylinder 32 and the stabilizing pipe 3. The coiled material fabric 22 and the second end rod 23 then bypass the second flattening cylinder 32 and pass through the above-mentioned gap;

[0036] Release the second flattening cylinder 32. Under the elastic force of the compression spring 34, the second flattening cylinder 32 presses against the stretched coiled material fabric 22 to prevent it from sagging. During the continuous stretching process of the coiled material fabric 22, the coiled material fabric 22 is subjected to the pressure of the second flattening cylinder 32, and the coiled material fabric 22 bypassing the second flattening cylinder 32 is in a flat state;

[0037] After that, continue to unfold the coiled material fabric 22. Pull the handle 51 outward. The handle 51 pulls the pull rod 52, the connecting plate 53 and the rolling cylinder 54. The connecting plate 53 compresses the compression spring 55, increasing the distance between the rolling cylinder 54 and the enclosure net frame 12, which is conducive to the second end rod 23 and the coiled material fabric 22 passing through;

[0038] Release the handle 51. Under the restoring elastic force of the compression spring 55, the rolling cylinder 54 presses against the coiled material fabric 22, which can limit it. During the laying and stretching process of the coiled material fabric 22, the rolling cylinder 54 tightly presses against the coiled material fabric 22 to prevent it from sagging and wrinkling. Moreover, the rolling cylinder 54 also plays a role in flattening the coiled material fabric 22. The bottom end of the moving plate 42 can be fixed to the enclosure net frame 12 by conventional means (such as hand-tightening a plum blossom screw);

[0039] In summary: There is a design on the protective frame that facilitates the installation of the waterproof coiled material. The coiled material fabric 22 and the second end rod 23 pass through the stabilizing pipe 3. The stabilizing pipe 3 limits the first end rod 21. During the laying and stretching process of the coiled material fabric 22, the rolling cylinder 54 tightly presses against the coiled material fabric 22 to prevent it from sagging and wrinkling. Moreover, the rolling cylinder 54 also plays a role in flattening the coiled material fabric 22. The waterproof coiled material and the protective frame are of a split design, which is convenient for replacing the waterproof coiled material.

[0040] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
