Description

Technical Field

[0001] The invention relates to the technical field of pipeline hoisting, and in particular to an industrial pipeline load-bearing hanger. Background Art

[0002] When installing industrial pipelines, special hangers are required to support the pipelines, and the hangers are removed after installation. Pipe hangers are used to bear the load of industrial pipelines and transfer the load to the structural load-bearing components. The structural design of pipe hangers is particularly important for the stability and safety of the overall pipeline system.

[0003] Existing pipe hangers, such as the one disclosed in patent publication number WO2021227485A1, are a kind of high-pressure pipe hanger for the coal chemical industry, which includes a support frame and a connector fixedly connected to the lower surface of the support frame, in which a hanger is installed, and the lower end of the hanger is fixedly connected to the base. The hanger has the following problems: (i) The hanger, the connector and the support frame are rigidly connected. When the pipeline is placed on the base, the hanger is loaded. The rigid connection causes the hanger to be subjected to shear stress and torsional stress, which is easy to cause deformation or failure at the connection between the hanger and the connector, or the connection between the connector and the support frame, affecting the use of the hanger; (ii) The hanger is a single-rod fixed structure, and the base for installing the pipeline cannot be adjusted in height. Summary of the invention

[0005] The technical solution of the present invention is: an industrial pipeline load-bearing hanger, comprising a crossbeam, a lifting lug, a first hanging rod, a fastener, a connecting piece, a second hanging rod and a pipe support for limiting the position of the industrial pipeline; the lifting lug is connected to the lower ends of both sides of the crossbeam in the X direction, the lifting lug is provided with a through hole for the first hanging rod to pass through, the upper end of the first hanging rod is provided with a slider, the slider is in contact with the upper surface of the lifting lug, the through hole passes through in the first direction X, the slider extends in the second direction Y, the first direction X and the second direction Y are perpendicular to each other on the same top projection plane; the lower end of the first hanging rod is connected to the upper end of the connecting piece by a fastener; the upper end of the second hanging rod is connected to the lower end of the connecting piece by a fastener, and the lower ends of the two second hanging rods are connected to the pipe support.

[0006] In the above scheme, a through hole is set on the lifting ear fixedly connected to the crossbeam. After the first hanging rod passes through the through hole, it is limited up and down by a slider and has a rotatable degree of freedom, thereby realizing a flexible connection between the lifting ear and the first hanging rod; when the pipe support is placed on the pipe, the first hanging rod can be adaptively rotated and adjusted due to the load, reducing the shear stress and torsional stress borne by the hanging rod, avoiding deformation and failure of the hanger, and extending its service life.
