Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology; specifically, it relates to a high-altitude assembly operation platform for large-diameter pipelines. Background Technology

[0002] In recent years, with the continuous expansion of production scale in industries such as chemical and metallurgy, construction units have demanded shorter construction cycles, effective reduction of resource consumption, early completion and commissioning to generate economic benefits and accelerate capital turnover. Under these circumstances, it is crucial to control each stage of the construction process and ensure the safe and high-quality completion of the process flow.

[0003] As the production capacity of the construction unit increases, the diameter of some process pipelines gradually increases. Therefore, during the construction of large-diameter pipelines in the pipe gallery, it is inevitable that some fixed weld joints will be suspended in the air. How to quickly complete the assembly and welding of pipeline welds and reduce economic costs such as labor and machinery? Therefore, this invention has emerged, namely, a high-altitude assembly operation platform for large-diameter pipelines. Utility Model Content

[0004] In view of this, the present invention provides a high-altitude assembly operation platform for large-diameter pipelines. By fixing it to the pipeline, it ensures the safety of operators while also facilitating assembly and welding, thereby ensuring the quality of pipeline construction and significantly reducing economic costs such as labor and machinery. This solves or at least alleviates the aforementioned problems in the prior art.

[0005] To achieve the aforementioned objectives, this utility model provides a high-altitude assembly operation platform for large-diameter pipelines, comprising:

[0006] The main structure has an opening that allows process pipes to be fitted from top to bottom. The opening is U-shaped, and the main structure has a lifting hole.

[0007] External platforms are located at the bottom of both sides of the main structure;

[0008] The movable springboard is located at the bottom of the main structure, and its two ends are placed on two external platforms respectively.

[0009] The protective cages are installed on both sides of the main structure and above the external platform.

[0010] Preferably, the main structure includes two main plates spaced apart front to back and a connecting rod connecting the two main plates. The lifting holes are all provided on the main plates, and the connecting rods are equidistantly arranged between the two main plates along the outline of the openings.

[0011] Preferably, the main body plate is a steel plate and the connecting rod is a steel pipe.

[0012] Preferably, the movable ramp is located between the two main boards in the front-to-back direction.

[0013] Preferably, the external platform and the protective cage connect the same side of the two main body plates.

[0014] Preferably, the top edge and both sides of the opening are provided with fixing bolts mounted on the main body plate to stabilize the operating platform.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. The large-diameter pipeline high-altitude assembly operation platform of this utility model is simple to manufacture, can be reused multiple times, and has low manufacturing cost.

[0017] 2. The large-diameter pipeline high-altitude assembly operation platform of this utility model is easy to install, simple to operate, and has good performance.

[0018] 3. The large-diameter pipe high-altitude assembly operation platform of this utility model can quickly make high-altitude welds ready for operation, ensure the safety of operators, shorten construction time, and reduce construction costs.

[0019] 4. When constructing large-diameter pipelines in pipe racks, the fixed weld joints of the pipelines are often suspended in the air, increasing the difficulty of high-altitude assembly and welding for workers and posing certain safety hazards. Conventional scaffolding construction increases construction time and is not conducive to cost control of personnel and machinery. This utility model's high-altitude assembly operation platform for large-diameter pipelines, by being fixed to the pipeline, ensures the safety of workers while also facilitating assembly and welding, thereby guaranteeing the quality of pipeline construction and significantly reducing economic costs such as labor and machinery.

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figure 1 and Figure 2 This utility model provides a high-altitude assembly operation platform for large-diameter pipelines, including a main structure 1, an external platform 2, a movable ramp 3, and a protective cage 4. The main structure 1 has an opening, U-shaped, that allows the process pipeline to be fitted from top to bottom. After the process pipeline is fitted through the opening, the inner arc of the opening fits over the top of the pipeline. The main structure 1 has lifting holes 6; specifically, in this embodiment, one lifting hole 6 is provided at each of the four corners of the top of the main structure 1. During use, the operation platform is placed onto the process pipeline by hoisting.

[0026] The external platform 2 is set at the bottom of both sides of the main structure 1, serving as the main standing platform for workers during high-altitude construction. At the same time, it also acts as a counterweight to both sides of the main structure 1, improving the stability of the operating platform.

[0027] The movable scaffold 3 is located at the bottom of the main structure 1, and its two ends are respectively mounted on two external platforms 2. Workers can stand on the movable scaffold 3 to weld the bottom seams of the process pipeline. Specifically, in this embodiment, the movable scaffold 3 is a steel scaffold. Furthermore, the two ends of the movable scaffold 3 are connected to the two external platforms 2, which further improves the stability of the operating platform.

[0028] The protective cage 4 is installed on both sides of the main structure 1 and above the external platform 2. When workers stand on the external platform 2, they are located inside the protective cage 4, providing better protection for them. At the same time, workers can climb up from inside the protective cage 4 across the side of the main structure 1 to reach the top of the process pipeline and lie on the main structure 1 to weld the top weld of the pipeline. At this time, the workers are still located inside the protective cage 4 in terms of height, further providing better protection for them.

[0029] Specifically, in this embodiment, the main structure 1 includes two main plates 1.1 spaced apart front to back and a connecting rod 1.2 connecting the two main plates 1.1. The hoisting holes 6 are all set on the main plates 1.1. The connecting rods 1.2 are equidistantly arranged between the two main plates 1.1 along the outline of the opening. The main plates 1.1 are steel plates and the connecting rods 1.2 are steel pipes.

[0030] Specifically, each main plate 1.1 has a lifting hole 6 on both sides of its top. The connecting rod 1.2 is located inside the main plate 1.1, allowing the area of ​​the main plate 1.1 outside the connecting rod 1.2 to protect the worker from both sides. The connecting rods 1.2 are spaced apart, providing footholds and handholds for workers climbing to the top of the process pipeline. This not only facilitates adjusting the worker's position but also provides stable support points for better protection. The gap between adjacent connecting rods 1.2 facilitates welding operations.

[0031] The movable scaffold 3 is positioned between the two main body plates 1.1 in the front-to-back direction. With this arrangement, both ends of the movable scaffold 3 pass through the two main body plates 1.1, allowing the main body plates 1.1 to limit the movable scaffold 3 from both sides, thereby improving the stability of the movable scaffold 3 and enhancing construction safety.

[0032] The external platform 2 and the protective cage 4 connect the same side of the two main body plates 1.1. Specifically, in this embodiment, the two sides of the external platform 2 and the protective cage 4 are welded between the two main body plates 1.1 to further improve the overall stability and strength of the operating platform and ensure construction safety.

[0033] The top edge and both sides of the opening are equipped with fixing bolts 5 mounted on the main body plate 1.1 to stabilize the operating platform. After the operating platform is hoisted onto the process pipeline and leveled and aligned, the main body structure 1 is fixed in place by operating the fixing bolts 5, thus stabilizing it on the process pipeline.

[0034] The steps of the operating platform manufacturing method described in this embodiment are as follows:

[0035] 1. Based on the dimensions of the welded pipes, 16mm Q235B steel plates are selected and cut to form the main body plate 1.1 of the main structure 1, which is the main load-bearing steel plate. Lifting holes 6 are provided on the top of the main body plate 1.1, and 5mm PTFE plates are installed on the top of the open arc, with protective pads provided to avoid damage to the process pipeline base material.

[0036] 2. Using φ48*3.0-Q235B welded steel pipe as connecting rod 1.2, the two main plates 1.1 are connected and fixed. Taking into account factors such as welding methods at various positions of the pipe weld and worker safety, the size and spacing of the connecting rod 1.2 at various positions are adjusted so that workers can stand on the scaffold to weld the bottom weld of the pipe, step on the connecting rod 1.2 to climb to the top of the pipe, and lie on the connecting rod 1.2 to weld the top weld of the pipe.

[0037] 3. The main structure 1 uses -40*4.0-Q235B flat steel to make protective cages on both sides of the top.

[0038] 4. Main Structure 1. External Platforms are installed on both sides of the bottom. 2. ∠50*5.0-Q235B angle steel, 4mm-Q235B patterned steel plate, -100*4.0mm-Q235B flat steel, φ48*3.0-Q235B welded steel pipe.

[0039] 5. Install fixing bolts 5 on the inner arc section of the main structure 1 steel plate to fix the operating platform.

[0040] 6. After the process piping is installed and in place, the main structure 1 of the operating platform is hoisted and fixed in place using hoisting machinery, and then the steel scaffolding between the external platforms 2 is installed and fixed.

[0041] 7. During operation, wind protection measures should be added, which can be done using platform railings and top guardrails.

[0042] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
