Description

Technical Field

[0001] This utility model relates to the technical field of large-diameter pipeline construction equipment, specifically a mobile windproof and heat-insulating protective shed for large-diameter pipeline construction. Background Technology

[0002] During the construction of large-diameter pipelines (such as long-distance oil and gas pipelines), harsh weather conditions are often encountered, especially environmental factors such as wind, sand, low temperature, rain and snow, which directly affect welding quality, construction safety and progress. At this time, protective sheds are needed to protect the construction area of ​​large-diameter pipelines and provide a stable working space for the construction of large-diameter pipelines. Existing thermal insulation protective sheds use directional wheels with foot brakes to provide mobile support. Once the protective shed is moved to the designated area, the foot brakes lock the directional wheels, thus locking the shed in place. At this point, the protective shed provides protective space for the construction area of ​​large-diameter pipelines. However, this type of protective shed has some problems. While locking the directional wheels with foot brakes provides support, the force between the directional wheels and the ground is limited, affecting the shed's grip and consequently its wind resistance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a mobile windproof and heat-insulating protective shed for large-diameter pipeline construction. By improving the grip of the protective frame, the overall support stability and windproof performance of the protective shed can be improved, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mobile windproof and heat-insulating protective shed for large-diameter pipeline construction, including a protective frame, the number of protective frames being three, an insulation cover being provided between the three protective frames, and movable wheels being provided at both ends of the lower surface of the protective frame, and also including a ground gripping mechanism; Ground gripping mechanism: It includes a fixed shaft, a rotating handle, a rotating seat, a fixed cylinder, ground gripping nails, and a disc. The fixed shafts are symmetrically fixed to the lower end of the protective frame. The outer surface of each fixed shaft is rotatably connected to the upper end of the vertically adjacent rotating handle. The lower end of each rotating handle is rotatably connected to a rotating seat. A fixed cylinder is fixedly connected to the middle of the rotating seat. Ground gripping nails are slidably connected inside the fixed cylinder. A disc is fixedly connected to the upper end of each ground gripping nail. By improving the ground gripping force of the protective frame, the overall support stability and wind resistance of the protective shed are improved.

[0005] Furthermore, the gripping mechanism also includes spiral ribs, which are uniformly fixedly connected to the outer surface of the gripping nail. The inner arc surface of the fixed cylinder is provided with uniformly distributed spiral rib grooves, which are slidably connected to adjacent spiral ribs to improve the friction between the gripping nail and the ground, thereby improving the gripping force of the gripping nail.

[0006] Furthermore, the gripping mechanism also includes limiting posts and limiting plates. The limiting posts are all fixedly connected to the middle of the rotating handle, and the lower end of the protective frame is fixedly connected to the limiting plates. The limiting plates are all installed in cooperation with the adjacent limiting posts to achieve the retraction of the rotating handle.

[0007] Furthermore, it also includes sliding grooves, which are respectively set at the left and right ends of the rear surface of the foremost protective frame, the left and right ends of the front surface of the rearmost protective frame, and the left and right ends of the middle protective frame. The lower end of each sliding groove is rotatably connected to a connecting rod, and the middle of each horizontally adjacent connecting rod is rotatably connected to a connecting shaft. The upper end of the inner wall on both sides of the sliding groove is provided with a guide groove, and a sliding rod is slidably connected between each horizontally adjacent guide groove inside the same sliding groove. The upper end of each connecting rod is rotatably connected to the middle of the adjacent sliding rod, so as to realize the linkage between the two adjacent protective frames and at the same time realize the stable support between the two adjacent protective frames.

[0008] Furthermore, the interior of the insulation cover is provided with evenly distributed mounting holes. The mounting holes in the middle and upper part of the insulation cover are connected to the outer surface of the protective frame through mounting posts. The lower ends of the ground anchors all penetrate the adjacent mounting holes at the lower end of the insulation cover. The front and rear ends of the insulation cover are provided with symmetrically distributed door curtains to realize the installation of the insulation cover without affecting personnel access and the coverage of large-diameter pipes.

[0009] Furthermore, it also includes fans, which are respectively installed on the upper end of the frontmost protective frame and the upper end of the rearmost protective frame. The input ends of both fans are electrically connected to the output ends of the external control switch group to accelerate the air exchange between the inside and outside of the protective shed.

[0010] Furthermore, the crossbeams at the upper end of the protective frame are provided with evenly distributed through holes. The through holes in the middle of the protective frame are connected to the upper end of the lighting lamp through pins. The input end of the lighting lamp is electrically connected to the output end of the external control switch group to provide lighting for the interior of the protective shed.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This mobile windproof and heat-insulating protective shed for large-diameter pipeline construction has the following advantages: The rotation of the handle enables the retraction and release of the gripping spikes, facilitating the transportation of the protective canopy. Simultaneously, the rotation of the rotating base effectively meets the connection requirements of the gripping spikes facing different work surfaces, ensuring that the gripping spikes can be stably driven into the ground. Furthermore, the spiral ribs enhance the interaction force between the ground and the gripping force, further improving the grip of the protective frame. Ultimately, this improves the overall support stability and wind resistance of the protective canopy. Compared to a single moving wheel foot brake locking method, the protective canopy has stronger grip and better wind resistance. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-6 This embodiment provides a technical solution: a mobile windproof and heat-insulating protective shed for large-diameter pipeline construction, including a protective frame 1, the number of protective frames 1 being three, with an insulation cover 10 set between the three protective frames 1, and movable wheels 7 set at both ends of the lower surface of the protective frame 1. The movable wheels 7 can be directional wheels with foot brakes commonly used in the prior art. The protective frame 1 is pushed along the axial direction of the large-diameter pipeline, and the movable wheels 7 roll to realize the overall movement of the protective shed. When the protective shed reaches the designated area, the pushing of the protective shed is stopped, and then the foot brakes of the movable wheels 7 at both ends of the middle protective frame 1 are stepped on to realize the rolling limit of the two movable wheels 7 in the middle. When both the front and rear protective frames 1 have reached the designated position, the pulling of the front and rear protective frames 1 is stopped, and then the foot brakes of the movable wheels 7 at both ends of the front and rear protective frames 1 are stepped on to realize the rolling limit of the movable wheels 7 on both sides. It also includes a ground gripping mechanism 2. The ground gripping mechanism 2 includes a fixed shaft 21, a rotating handle 22, a rotating seat 23, a fixed cylinder 24, ground gripping spikes 25, and a disc 29. The fixed shafts 21 are symmetrically fixed to the lower end of the protective frame 1. The outer surface of each fixed shaft 21 is rotatably connected to the upper end of the vertically adjacent rotating handle 22. The lower end of each rotating handle 22 is rotatably connected to the rotating seat 23. The middle of the rotating seat 23 is fixedly connected to the fixed cylinder 24. The ground gripping spikes 25 are slidably connected inside the fixed cylinder 24. The upper end of each ground gripping spike 25 is fixedly connected to the disc 29. The ground gripping mechanism 2 also includes spiral ribs 26, which are uniformly fixed to the ground gripping spikes. The outer surface of the 25 and the inner arc surface of the fixed cylinder 24 are provided with evenly distributed spiral rib grooves. The spiral rib grooves are slidably connected to the adjacent spiral ribs 26. The gripping mechanism 2 also includes limiting posts 27 and limiting plates 28. The limiting posts 27 are all fixedly connected to the middle of the rotating handle 22. The lower end of the protective frame 1 is fixedly connected to the limiting plates 28. The limiting plates 28 are all installed in cooperation with the adjacent limiting posts 27. When the protective shed reaches the designated area, the pushing of the protective shed is stopped, and then the foot brakes of the moving wheels 7 at both ends of the middle protective frame 1 are stepped on to realize the rolling limit of the two moving wheels 7 in the middle. Then, the middle protective frame 1 is first moved. The operation of the gripping mechanisms 2 at both ends involves rotating the rotating handle 22 counterclockwise. The rotating handle 22 rotates 180 degrees counterclockwise around the central axis of the adjacent fixed column 21. At this time, the limiting column 27 in the middle of the rotating handle 22 stops contacting the adjacent limiting plate 28. When the rotating handle 22 rotates to the vertical position, the rotation of the rotating handle 22 stops. Then, the rotating seat 23 is rotated. The rotating seat 23 rotates in the vertical direction. When the lower surface of the rotating seat 23 is parallel to the working surface, the corresponding gripping nail 25 is rotated through the disc 29. Since the spiral ribs 26 on the outer surface of the gripping nail 25 are all slidingly connected with the adjacent spiral rib grooves inside the fixed cylinder 24, the gripping nail 25 is rotated. Next, the ground-gripping spike 25 moves downward during rotation and drives into the ground. At the same time, the spiral rib 26 contacts the ground, increasing the friction between the outer surface of the ground-gripping spike 25 and the ground, thereby increasing the gripping force of the ground-gripping spike 25. This achieves the locking of the position of the central protective frame 1. When both the front and rear protective frames 1 reach the designated position, the pulling of the front and rear protective frames 1 stops. Then, the ground-gripping mechanism 2 on the front and rear sides is operated according to the above principle to achieve a stable connection between the ground-gripping spikes 25 on the front and rear sides and the ground. Finally, the entire protective shed is fixed, effectively improving the gripping force of the protective shed and thus improving the overall wind resistance of the protective shed. This includes: a sliding groove 3, which is respectively located at the left and right ends of the rear surface of the foremost protective frame 1, the left and right ends of the front surface of the rearmost protective frame 1, and the left and right ends of the middle protective frame 1. A connecting rod 4 is rotatably connected to the lower end of each sliding groove 3. A connecting shaft is rotatably connected between the middle of two laterally adjacent connecting rods 4. Guide grooves 5 are provided at the upper ends of the inner walls on both sides of the sliding groove 3. A sliding rod 6 is slidably connected between two laterally adjacent guide grooves 5 located within the same sliding groove 3. The upper end of each connecting rod 4 is connected to an adjacent sliding rod 6. The middle part is rotated and connected. After the middle protective frame 1 is locked and stabilized, the front protective frame 1 is pulled forward and the rear protective frame 1 is pulled backward. During the outward movement of the front and rear protective frames 1, the lower end of the connecting rod 4 rotates with the lower end of the adjacent slide groove 3. Under the linkage of the connecting shaft, the upper end of the two horizontally adjacent connecting rods 4 moves downward inside the corresponding slide groove 3. At the same time, the slide rod 6 at the upper end of the connecting rod 4 slides downward between the two adjacent guide grooves 5, providing guidance and limiting function for the vertical movement of the upper end of the connecting rod 4. The insulation cover 10 has evenly distributed mounting holes inside. The mounting holes in the middle and upper part of the insulation cover 10 are connected to the outer surface of the protective frame 1 through the mounting posts 12. The lower ends of the ground anchors 25 all penetrate the adjacent mounting holes at the lower end of the insulation cover 10. After the ground anchors 25 are driven into the ground, the lower end of the insulation cover 10 is tightly attached to the ground. The front and rear ends of the insulation cover 10 are equipped with symmetrically distributed curtains 11. Both the insulation cover 10 and the curtains 11 can be made of tarpaulin made of film-coated felt. Film-coated felt is a composite material made of needle-punched synthetic felt made of mixed materials such as cotton felt, acrylic cotton, and space cotton as the base material and covered with polyethylene high-molecular virgin resin film. Film-coated felt has the characteristics of being waterproof and snowproof, UV resistant, acid and alkali resistant, having a high coefficient of friction and being lightweight. It has good thermal insulation performance and can effectively meet the protection and thermal insulation needs of the protective shed when working outdoors, reducing the impact of harsh weather on the construction of large-diameter pipelines. The system also includes fans 8, which are respectively located at the top of the frontmost protective frame 1 and the top of the rearmost protective frame 1. The rectangular openings at both ends of the insulation cover 10 are equipped with filters, which are longitudinally aligned with the fans 8 to prevent external impurities from entering the interior of the protective shed without affecting the air exchange effect. The input ends of both fans 8 are electrically connected to the output ends of the external control switch group. The external control switch group enables the operation of the two fans 8. The operation of the front fan 8 introduces external air into the interior of the protective shed from front to back, and the operation of the rear fan 8 draws the air inside the protective shed from front to back to the outside, thus accelerating the air exchange between the inside and outside of the protective shed. The protective frame 1 has evenly distributed through holes in the middle of the crossbeam at the top. The through holes in the middle of the protective frame 1 are connected to the upper end of the lighting lamp 9 through pins. The input end of the lighting lamp 9 is electrically connected to the output end of the external control switch group. During the use of the protective shed, the lighting lamp 9 is installed inside the through holes in the crossbeam of the protective frame 1. The lighting lamp 9 is turned on through the external control switch group to provide lighting service for the interior of the protective shed.

[0016] The working principle of the mobile windproof and heat-insulating protective shed for large-diameter pipeline construction provided by this utility model is as follows: During operation, personnel first place the protective shed in the construction area of ​​the large-diameter pipeline, ensuring the pipeline runs longitudinally through it. Simultaneously, the end of the curtain 11 closest to the center of the protective frame 1 is attached to the outer surface of the large-diameter pipeline. Then, personnel push the protective frame 1 along the axial direction of the large-diameter pipeline, causing the moving wheels 7 to roll and move the entire protective shed. When the protective shed reaches the designated area, personnel stop pushing it and then depress the foot brakes on the moving wheels 7 at both ends of the central protective frame 1 to limit their rolling. Next, personnel operate the ground-gripping mechanisms 2 at both ends of the central protective frame 1, rotating them counterclockwise. The rotating handle 22 rotates 180 degrees counterclockwise around the central axis of the adjacent fixed column 21. At this time, the limiting column 27 in the middle of the rotating handle 22 stops contacting the adjacent limiting plate 28. When the rotating handle 22 rotates to the vertical position, the rotation of the rotating handle 22 stops, and then the rotating seat 23 rotates. The rotating seat 23 rotates in the vertical direction. When the lower surface of the rotating seat 23 is parallel to the working surface, the personnel rotate the corresponding ground anchor 25 through the disc 29. Since the spiral ribs 26 on the outer surface of the ground anchor 25 are all slidably connected to the adjacent spiral rib grooves inside the fixed cylinder 24, the ground anchor 25 moves down during rotation and is driven into the ground. At the same time, the spiral ribs 26 contact the ground, increasing the friction between the outer surface of the ground anchor 25 and the ground. To improve the grip of the ground anchor 25, thereby locking the position of the central protective frame 1, personnel then pull the front protective frame 1 forward and the rear protective frame 1 backward. During the outward movement of the two protective frames 1, the lower ends of the connecting rods 4 rotate with the lower ends of the adjacent sliding grooves 3, and the upper ends of the two laterally adjacent connecting rods 4 move downward inside the corresponding sliding grooves 3 under the linkage of the connecting shaft. At the same time, the sliding rods 6 at the upper end of the connecting rods 4 slide downward between the two adjacent guide grooves 5, providing guidance and limiting for the vertical movement of the upper end of the connecting rods 4. When both the front and rear protective frames 1 reach the designated position, the pulling of the two protective frames 1 is stopped, and then the foot brakes of the moving wheels 7 at the left and right ends of the two protective frames 1 are depressed. The rolling limit of the front and rear moving wheels 7 is now set. Then, personnel operate the front and rear gripping mechanisms 2 according to the above principle to achieve a stable connection between the gripping nails 25 on the front and rear sides and the ground, ultimately fixing the entire protective shed. This effectively improves the grip of the protective shed and thus enhances its overall wind resistance. At the same time, the adjacent connecting rods 4 provide support for the protective frame 1, increasing the support strength on the left and right sides of the protective shed. During the use of the protective shed, the lighting lamps 9 are installed inside the through holes of the crossbeams of the protective frame 1. The lighting lamps 9 are turned on through the external control switch group to provide lighting for the interior of the protective shed. At the same time, the external control switch group enables the operation of the front and rear fans 8. The operation of the front fan 8 introduces outside air into the interior of the protective shed from front to back.The rear fan (8) draws air from inside the protective canopy to the outside from front to back, accelerating air exchange between the inside and outside of the canopy.

[0017] It is worth noting that the external control switch group disclosed in the above embodiments is equipped with control buttons that correspond one-to-one with the fan 8 and the lighting lamp 9 and control their switching.

[0018] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
