Description

Technical Field

[0001] The utility model relates to an auxiliary ladder frame for large-diameter pipeline operations, belonging to the technical field of large-diameter pipeline installation operations. Background Art

[0002] At present, in the installation and construction of large-diameter pipelines, there is often a problem that the pipeline diameter is too large and the operators cannot directly approach the work point, but the construction of pipeline connection, grinding, welding, etc. must ensure that the operators can approach the work point. The most commonly used domestic solutions are to use three temporary solutions.

[0003] Option 1: Set up scaffolding at the location where the pipeline needs to be constructed.

[0004] Option 2: Use a ladder to lean against the pipeline, and workers climb the ladder to carry out construction.

[0005] Option three: Use wooden boxes to build steps, and workers stand on the steps to carry out construction.

[0006] However, the above conventional solutions have the following problems:

[0007] (1) Plan 1 requires the erection of scaffolding, which requires a large amount of scaffolding materials and professional scaffolding workers. In addition, in general pipeline construction areas, material transportation is difficult due to excavation and other reasons. This plan is costly and has a long construction period, and cannot meet actual needs in a timely manner.

[0008] (2) Option 2: Ladders are prone to slipping when leaning against the pipe, so a fixed solution is required. The coverage of the ladder is limited, and workers need to climb up and down the ladder repeatedly when adjusting the construction position. This increases safety risks and construction time. To ensure safety, special personnel need to be arranged to support the ladder, which increases labor. In addition, outdoor construction is inconvenient in adverse weather such as rain, snow, and strong winds. This solution is rarely used at present.

[0009] (3) Option 3 is less efficient and labor-intensive. Since the materials for building the steps are often locally sourced, the stability of the steps is difficult to control, which increases safety risks. In addition, during outdoor construction, in adverse weather such as rain, snow, and strong winds, temporary steps cannot be protected, making construction inconvenient. Currently, this option is only applicable to some situations where the amount of construction work is small.

[0010] In summary, the three solutions all have their own shortcomings, so it is quite necessary to design a large-diameter pipeline operation auxiliary equipment with a simple structure, easy installation, and both safety and improved operation efficiency. Utility Model Content

It can both ensure safety and improve operation efficiency, and is highly practical.

[0012] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0014] Preferably, the main frame includes four U-shaped steel pipes distributed in a rectangular shape, the flat plate connecting frame is rectangular, and the U-shaped steel pipes are respectively welded to the corners of the flat plate connecting frame.

[0015] Preferably, the ladder rod is welded between two U-shaped steel pipes and is located on the inner side of the main frame opposite to the large-diameter pipe, and a ladder rod is arranged between adjacent flat plate connection frames.

[0016] Preferably, the main frame has an isolation support rod extending from the inner side of the main frame and contacting the top of the large-diameter pipe, and the isolation support rod separates the main frame from the large-diameter pipe by 10 to 30 centimeters.

It is characterized in that it includes a U-shaped main frame 1 supported on the top of the large-diameter pipeline, support feet 2 and a platform plate 3 fixed to the bottom of the main frame and in contact with the ground, flat plate connecting frames 4 are evenly spaced on the main frame 1, ladder rods 5 are arranged between adjacent flat plate connecting frames 4, and the platform plate 3 is detachably snap-connected to the flat plate connecting frame 4.

[0025] The large-diameter pipeline operation auxiliary ladder frame described above is erected across the large-diameter pipeline 100, the supporting feet 2 are in contact with the ground, the main frame 1 is supported on the top of the large-diameter pipeline 100, and the platform plate 3 can be snap-connected to the flat plate connection frame. During operation, the operator can climb to the position of the flat plate connection frame 4 with the help of the ladder rod 5, and snap-connect the platform plate 3 to the flat plate connection frame 1. The operator can stand on the platform plate 3 to operate the large-diameter pipeline, or climb to the top of the large-diameter pipeline with the help of the ladder rod 5 and the flat plate connection frame 4 to operate it, so as to assist the operator to quickly approach the operation point. The auxiliary ladder frame has a simple structure and is easy to be erected on the large-diameter pipeline 100. It can provide standing and climbing support for the operator to approach the operation point during the large-diameter pipeline installation operation, and use the large-diameter pipeline 100 to support the auxiliary ladder frame to prevent the auxiliary ladder frame from tipping over and tipping over, thereby improving the safety of the operation, ensuring safety and improving the operation efficiency. It is highly practical, and a rainproof cloth can be covered on the auxiliary ladder frame in rainy, snowy and windy weather to improve the convenience of outdoor construction.

[0026] The main frame 1 includes four U-shaped steel pipes 11 distributed in a rectangular shape, the flat plate connection frame 4 is rectangular, and the U-shaped steel pipes 11 are welded to the corners of the flat plate connection frame 4. The U-shaped steel pipes 11 are welded to form a whole through the flat plate connection frame 4, and the flat plate connection frame 4 is evenly spaced on the main frame 1 to ensure the strength of the main frame 1. The four U-shaped steel pipes 11 are connected to the flat plate connection frame 4 to form a main frame 1 with a hollow channel structure, which is convenient for operators to be in the hollow channel structure when climbing and standing, and acts as a fence around the operators, which can effectively prevent the operators from falling off and improve safety.

[0027] The ladder rod 5 is welded between two U-shaped steel pipes 11 and is located on the inner side of the main frame 1 opposite to the large-diameter pipe. A ladder rod 5 is provided between adjacent flat plate connection frames 4. The ladder rod 5 is used for climbing by the operator. When the flat plate connection frame 4 is buckled with the overlapping platform plate 3, the operator can stand and work. When the overlapping platform plate 3 is not buckled, the operator can climb, and the operator is assisted to quickly climb to the top of the large-diameter pipe.
