Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline assembly tools, and more specifically, particularly relates to a hydraulic pipe support with adjustable height and angle. Background Art

[0002] A pipeline gas transmission station is various operating stations established for pipeline transmission of natural gas or associated petroleum gas. According to the position of the compressor station along the pipeline, it is divided into a starting compressor station, intermediate compressor stations, and an end gas filling station. Different gas stations have different functions and realize different functions. The same is that a large number of pipelines will be set up in different gas transmission stations to meet the corresponding functions. Therefore, pipeline layout and assembly is one of the main tasks in the preliminary construction of gas transmission stations, which requires a large amount of manpower and material resources. Especially when it comes to welding or assembling between two pipelines, the axes of the two pipelines need to be aligned. Generally, a hydraulic pipe support is used to lift and align the pipeline. The existing hydraulic pipe support generally has a V-shaped groove, and the pipeline is placed inside the pipe support to achieve the lifting and supporting of the pipeline.

[0003] The existing application number is: CN202020026111.0. The utility model relates to a height-adjustable pipe support for a gas transmission station, belonging to the technical field of pipeline assembly tools. It includes a base, a lifting mechanism, and a fine-tuning mechanism. The lifting mechanism includes a hydraulic cylinder fixed at the center of the base and a mounting seat fixed at the upper end of the hydraulic cylinder. The fine-tuning mechanism includes two slide rails fixed on the mounting seat and two sliding seats slidably arranged on the slide rails. There are two bearing seats between the two slide rails on the mounting seat, and a screw rod is arranged in the bearing seats. A pipeline support device is arranged at the top of the sliding seat. The height-adjustable pipe support for the gas transmission station of the utility model realizes the preliminary positioning of the pipeline height through the lifting mechanism and the precise positioning of the pipeline height through the fine-tuning mechanism, which greatly facilitates the pipeline assembly operation of the gas transmission station. In addition, the cooperation of the guide cylinder and the guide post ensures the stable lifting of the mounting seat. The material of the rolling shaft is selected from rubber or polyurethane to reduce the collision when contacting the pipeline and play a certain protective role.

[0004] Based on the above, due to the V-shaped structure of the existing hydraulic pipe support, it generally can only lift straight pipes. However, when welding natural gas pipelines, many right-angle elbows are required for connection. When lifting elbows, generally two sets of hydraulic pipe supports are needed for support, which affects the application range of the hydraulic pipe support. Summary of the Utility Model
