Description

Technical Field

[0001] This utility model relates to the technical field of protective air cushions, specifically a safety protective air cushion for large-size vertical pipeline work platforms. Background Technology

[0002] In the installation, welding, inspection, and maintenance of large-scale vertical pipelines in industries such as petrochemicals, power, and shipbuilding, including chimneys, reaction towers, and wind turbine towers, workers must operate from elevated work platforms surrounding the pipelines. These operations face extremely high risks of falls from heights, and traditional safety ropes offer limited protection and are prone to failure. Furthermore, the platform is susceptible to collisions and friction with the pipelines during lifting and lowering, leading to instability and failing to provide effective protection for this specific working environment. Utility Model Content

[0003] The purpose of this invention is to provide a special safety air cushion for large-size vertical pipeline work platforms, which is easy to assemble, solves the problem of fall protection from heights, and greatly protects the safety of construction workers.

[0004] To achieve the above objectives, this utility model provides a special safety air cushion for large-size vertical pipeline work platforms, comprising:

[0005] Two arc-shaped frames that can be joined together to form a circle are connected to each other by multiple assembly plates.

[0006] An arc-shaped mounting plate is fixed to the bottom of the arc-shaped frame, and its curvature is consistent with that of the arc-shaped frame;

[0007] The first airbag is installed at the bottom of the mounting plate. It is arc-shaped and has multiple partition layers inside, forming multiple independent airbag spaces.

[0008] The first rubber pad is disposed on the side of the first airbag.

[0009] The independent airbag space ensures that even if some airbags rupture, the overall system still has cushioning capabilities; the first rubber pad on the side can effectively prevent the airbags from being punctured by pipes or obstacles during lifting, significantly improving the reliability and durability of the safety device.

[0010] In a further technical solution, an air pump is provided inside the mounting plate, and the air pump is connected to the space of each airbag.

[0011] This enables the safety air cushion to be self-inflating, eliminating the need for an external air source, thus improving the convenience and independence of the work, and facilitating rapid deployment and use at high-altitude or remote work sites.

[0012] A further technical solution also includes an arc-shaped base plate, which is connected to the mounting plate via a spring shock absorber and is located below the first airbag.

[0013] By adding a base plate and spring shock absorbers, a two-stage buffer system is formed. The spring shock absorbers first absorb and disperse a portion of the impact energy, and then the first airbag provides secondary cushioning, greatly enhancing the overall buffering effect and further reducing the injury to personnel and the platform from the impact of the fall.

[0014] In a further technical solution, a second airbag is fixed to the bottom surface of the base plate. The second airbag is provided with an inflation port with a one-way valve and an exhaust port with a sealing cap.

[0015] A third-level buffer (second airbag) is added to the two-level buffer system, forming multiple energy-absorbing protection layers. The structure with a one-way valve and sealing cap facilitates inflation and pressure adjustment, allowing the protection system to adapt to different buffering needs and greatly enhancing safety performance.

[0016] A further technical solution is that a retractable first telescopic rod is installed on the inner arc surface of the mounting plate, and a roller is rotatably provided at one end of the first telescopic rod.

[0017] The design of the first telescopic rod and rollers allows the work platform to roll close to the outer wall of the pipe during lifting, providing guidance and stability. This effectively prevents the platform from rotating, swaying, or colliding with the pipe, protecting the first airbag and ensuring a smooth and safe operation. The telescopic rod can be retracted at pipe connections.

[0018] A further technical solution is that a retractable second telescopic rod is installed on both sides of the first telescopic rod, and a second rubber pad is fixed to one end of the second telescopic rod.

[0019] Based on the guidance system, an active clamping and fixing function has been added. The second telescopic rod can extend and press the second rubber pad tightly against the pipe wall to temporarily fix the platform to the pipe, preventing it from shaking during operation and providing workers with an extremely stable and reliable working platform.

[0020] In a further technical solution, the outer edge of the base plate is hinged with multiple protective rods, and the protective rods are provided with multiple first rope buckles for fixing the side protective net.

[0021] This feature constitutes the side fall protection system. The articulated guardrail can be deployed to form a protective area. Through the protective net fixed with rope buckles, it can effectively prevent personnel or tools from falling from the side of the platform, achieving all-round protection and further improving safety.

[0022] A further technical solution is that the two ends of the base plate are provided with a number of second rope fasteners for installing the bottom protective net; the two inner ends of the base plate are also provided with vertical rods for installing the inner protective net.

[0023] The bottom protective netting prevents small parts from falling, while the inner protective netting prevents people from slipping towards the center of the pipe. Together with the side protective netting, they form a complete fall-prevention safety space, fully protecting personnel safety.

[0024] A further technical solution is that each airbag space has a one-way valve on its inflation port and an exhaust port with a sealing cap.

[0025] One-way valves prevent gas backflow and ensure inflation efficiency; vents with sealed caps allow for active adjustment of pressure in each airbag space, and even rapid deflation for retraction or maintenance, improving the adjustability and ease of use of the equipment.

[0026] In a further technical solution, the second airbag is a disposable structure and does not have an exhaust port.

[0027] Another preferred implementation scheme for the second airbag is provided. The design of non-venting airbags eliminates the risk of slow air leakage caused by poor sealing of the vent, and maximizes the reliability of safety cushioning, making it suitable for occasions with extremely high safety requirements.

[0028] In summary, this utility model has the following beneficial effects: By providing a work platform composed of a splicable arc-shaped structure and integrating a multi-level dedicated safety air cushion system, this utility model patent achieves a high level of overall safety. Specifically: 1. The multi-level buffer system, consisting of an independently compartmented first airbag, spring shock absorbers, and a second airbag, along with a disposable airbag option, ensures effective protection even in the event of partial failure; 2. The installation of side, bottom, and inner protective nets creates a three-dimensional fall-prevention safety space; 3. Good working stability: The retractable guide wheels and clamping device ensure smooth platform lifting and firm fixation during operation, avoiding the risk of tipping over and shaking; 4. High durability: The design of the anti-friction first rubber pad on the side effectively extends the service life of the safety air cushion; This device effectively solves the problem of high-altitude fall protection during large-size vertical pipeline operations, greatly ensuring the safety of construction personnel.

[0041] like Figures 1-5 As shown, a special safety protective air cushion for a large-size vertical pipeline work platform is provided. The work platform includes two semi-circular arc-shaped frames 11 spliced ​​together, and the two arc-shaped frames 11 are connected by several splicing plates 13.

[0042] Specifically, bolt holes are provided at both ends of the two arc-shaped frames 11, and bolt holes are also provided on the assembly plate 13. By connecting the two arc-shaped frames 11 together, a circular working platform surrounding the vertical pipe 10 is formed. The bolt holes on the assembly plate 13 are aligned with the bolt holes on the two arc-shaped frames 11, and bolts are inserted for fixing, thereby aligning and fixing the two arc-shaped frames 11. The assembly plate 13 can be set on the upper and lower sides of the arc-shaped frames 11 to enhance the splicing strength of the two arc-shaped frames 11.

[0043] In one embodiment, a handrail 12 may be provided on the curved frame 11 to prevent workers from falling while working.

[0044] The dedicated safety airbag includes a mounting plate 15 fixed to the bottom of the arc-shaped frame 11. The mounting plate 15 is arc-shaped, consistent with the arc shape of the arc-shaped frame 11. A first airbag 14 is installed at the bottom of the mounting plate 15. The first airbag 14 is also arc-shaped, and multiple partition layers 26 are provided inside the first airbag 14 to divide the internal space of the first airbag 14 into several independent airbag spaces 28. A first rubber pad 27 is provided on the side of the first airbag 14 to prevent the first airbag 14 from puncturing and leaking air when the work platform is raised and lowered due to friction between the first airbag 14 and the vertical pipe 10 or other objects.

[0045] In one embodiment, an air pump is provided inside the mounting plate 15, which can communicate with several airbag spaces 28 and inflate each airbag space 28.

[0046] Specifically, each inflation port connected to the airbag space 28 is equipped with a one-way valve, and each airbag space 28 is equipped with an exhaust port, which is fitted with a sealing cap.

[0047] In one embodiment, the difference between this embodiment and the previous embodiment is that, in order to enhance the sealing performance, the first airbag 14 in this embodiment is set to be disposable and does not have an exhaust port to prevent poor sealing and air leakage.

[0048] In one embodiment, a telescopic first telescopic rod 18 is installed on the inner arc surface of the mounting plate 15. One end of the first telescopic rod 18 is rotatably provided with a roller. When the roller moves up and down on the work platform, it rolls against the outer wall of the vertical pipe 10, so that the work platform can remain coaxial with the vertical pipe 10 and prevent the first airbag 14 from colliding and rubbing against the vertical pipe 10.

[0049] In one embodiment, a telescopic second telescopic rod 16 is installed on both sides of the first telescopic rod 18. A second rubber pad 17 is fixed to one end of the second telescopic rod 16. The second rubber pad 17 can abut against the outer wall of the vertical pipe 10 and clamp the vertical pipe 10, so that the vertical pipe 10 and the working platform remain relatively stationary and stable.

[0050] In one embodiment, a bottom plate 22 that can move up and down is provided at the bottom of the mounting plate 15. The bottom plate 22 is also arc-shaped, and the curvature of the bottom plate 22 is consistent with that of the mounting plate 15, that is, the arc axis of the mounting plate 15 is consistent with the arc axis of the bottom plate 22. Spring shock absorbers 19 are fixed at both ends of the bottom surface of the mounting plate 15. The spring shock absorbers 19 can elastically extend and retract. The other ends of the two spring shock absorbers 19 are respectively fixed at both ends of the bottom plate 22. The bottom plate 22 is located at the bottom of the first airbag 14. The mounting plate 15, the first airbag 14, and the bottom plate 22 are arranged in an upper, middle, and lower spatial distribution.

[0051] In one embodiment, a second airbag 25 is fixed on the bottom surface of the base plate 22.

[0052] Specifically, the second airbag 25 is provided with an inflation port. After assembly, the second airbag 25 is inflated through the inflation port. A one-way valve is provided inside the inflation port to prevent gas from being released. The second airbag 25 is also provided with an exhaust port, and a sealing cap is installed on the exhaust port.

[0053] In one embodiment, the difference between this embodiment and the previous embodiment is that the second airbag 25 does not have an exhaust port, thus enhancing the sealing performance.

[0054] In one embodiment, a plurality of protective rods 20 are provided on the outer edge of the base plate 22. The protective rods 20 are hinged to the base plate 22. A plurality of evenly distributed first rope buckles 21 are provided on the protective rods 20. A side protective net is installed between the plurality of protective rods 20. The side protective net is attached to the plurality of first rope buckles 21 and forms a frustum-shaped protective area that radiates from bottom to top to prevent people from falling.

[0055] In one embodiment, a plurality of second rope fasteners 24 are provided at both ends of the arc-shaped length direction of the base plate 22, and a bottom protective net is provided between two adjacent base plates 22. The bottom protective net is installed between the two base plates 22 by being fastened to the second rope fasteners 24.

[0056] In one embodiment, vertical rods 23 are installed at both ends of the inner side of the base plate 22. The vertical rods 23 are perpendicular to the base plate 22 and are used to install the inner protective net. The inner protective net is installed between two adjacent vertical rods 23.

[0057] In use, the workers splice the two arc-shaped frames 11 together around the vertical pipe 10, and then connect them to the assembled work platform through a tower crane or other lifting platform, so that the work platform can move up and down along the vertical pipe 10, and the workers stand on the arc-shaped frames 11 to carry out the work.

[0058] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0059] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
