Description

Technical Field

[0001] The utility model relates to the field of pipeline support frames, in particular to a supporting and fixing device for municipal pipeline construction. Background Art

[0002] In municipal pipeline construction, pipelines located on the ground need to be supported by pipeline supports so that the support can bear the pressure of the pipeline and restrain the pipeline to achieve the fixing effect of the pipeline.

[0003] When laying the pipeline, in order to avoid displacement of the pipeline due to ground collapse, multiple bases are usually built on the pipeline laying route, and then the support frame is installed on the base to stabilize the pipeline. At present, there are many types of devices used for pipeline support. For example, a Chinese patent with publication number CN117189951A discloses a pipeline support device for water supply pipeline construction, which includes a base and a connecting pipe. Two groups of support cylinders are installed on the top of the base and connected through a connecting pipe. The front of the connecting pipe is connected and installed with an adjustment mechanism. The internal sealing sleeve of the support cylinder is provided with a telescopic column. The top of the telescopic column is provided with a limited position installation mechanism; the limited position installation mechanism is composed of an upper clamping seat and a lower clamping seat hinged up and down, and the lower clamping seat and the upper clamping seat are provided with a transmission cavity inside; the device provided by the above patent is used to make the bonding plate fully fit under the double clamping of the top column and the pipeline, and the cushion is used to provide buffering. The upper and lower groups of bonding plates that are synchronously bent and deformed generate a uniform rigid clamping force on the outer wall of the pipeline, which not only fixes the force evenly, but also can adapt to pipelines of different sizes, and can be used in the same process of adaptation. The pipe groove is fixed on the support by the support pillar, and also includes a fixing rib and a supporting rod. The upper ends of the pipe groove are bent outward to form folded ears. A cap is provided on the outer side of the upper end of the pillar. One end of the supporting rod is fixedly connected to the folded ear, and the other end of the supporting rod passes through the cap and is fixed by a fastening nut. The two ends of the fixing rib are fixed to the folded ear, and the fixing rib and the pipe groove are fully covered with the oil pipeline. The groove surface of the pipe groove is provided with a convex ridge along the axial direction, and the bottom surface of the pipe groove is provided with a drainage hole. The pipe groove provided by this patent is stable and will not be deformed. At the same time, the oil pipeline placed on the pipe groove is stable and will not move. There will be no accumulation in the pipe groove, which prevents the oil pipeline from being eroded by rainwater.

[0004] When the base is constructed, the adjacent bases are far apart and cannot be accurately referenced relative to each other. Due to artificial construction errors, the top surface of the base is uneven, and the top surfaces of multiple bases are very likely not on the same plane. Therefore, when laying the pipeline, a support frame is needed to make up for this defect. The support device provided by the above patent, although it has different functions while meeting the premise of supporting the pipeline, is inconvenient to adjust its own height and the inclination angle of the top surface according to the installation environment. Therefore, it is not suitable for laying pipelines with more complex installation environments, or it needs to be divided and welded by welding equipment, cutting equipment, etc. to adjust the height of the support frame. Although this adjustment method can realize the installation of the pipeline support frame, the operation is cumbersome and the efficiency is low, which has a great impact on the laying of the entire pipeline.
