Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction, in particular to a positioning and alignment structure for pipeline fixing. Background Art

[0002] The main way to fix pipelines to each other is to use flanges and bolts in cooperation. There are holes in the flanges through which bolts can pass. Each of the two flanges is fixed to a pipeline respectively. A flange gasket is added between the two flanges and tightened with bolts, thus completing the connection of the two pipelines. Flange connection is an important connection method in pipeline construction. Flange connection is convenient to use and can withstand relatively large pressure. In industrial pipelines, flange connection is widely used.

[0003] The existing fixing method for pipelines and flanges is mainly welding. Usually, two operators are required. One or two operators hold the pipeline and the flange and manually align the pipeline and the flange, and the remaining one operator welds. The traditional welding method for pipelines and flanges has the following disadvantages:

[0004] 1. During the process of welding a pipeline to a flange, manual positioning and fixing are required, which is prone to shaking and displacement, making it difficult to ensure the centering of the pipeline and the flange and unable to guarantee the centering accuracy of the pipeline and the flange.

[0005] 2. During the flange welding process, at least two people are often required to operate the centering of the pipeline and the flange. The welding efficiency is low, affecting the construction progress. At the same time, the operation ability requirements for the operators are high. Summary of the Utility Model

[0006] Aiming at the technical problems existing in the existing pipeline and flange welding construction process, the technical problem to be solved by the utility model is to provide a positioning and alignment structure that can quickly complete the welding work of pipelines and flanges, significantly shorten the welding time, thereby improving work efficiency, only requiring one operator to complete the welding of pipelines and flanges, reducing the input of labor costs, and improving the welding quality of pipelines and flanges.

[0007] To solve the existing technical problems, the utility model provides a positioning and alignment structure for pipeline fixing. The positioning and alignment structure includes a plurality of groups of adjustable support components, a plurality of positioning angle steels, and support fixing parts. The plurality of groups of adjustable support components are distributed at intervals on the outer periphery of the support fixing part. One end of each group of adjustable support components is connected to the support fixing part, and the other end of each group of adjustable support components is connected to the lower end of each positioning angle steel. The positioning and alignment structure is tightly abutted against the inner wall of the pipeline through the top end of each positioning angle steel. A hanging part that can extend out of the outer part of the pipe orifice is formed on the left side of each positioning angle steel. Each positioning angle steel is hung with a flange through the hanging part.

[0008] Furthermore, several groups of adjustable support components include three groups of adjustable support components, namely the first adjustable support component, the second adjustable support component, and the third adjustable support component. Several positioning angle steels include three groups of positioning angle steels, namely the first positioning angle steel, the second positioning angle steel, and the third positioning angle steel. One ends of the first adjustable support component, the second adjustable support component, and the third adjustable support component are respectively connected to the outer periphery of the support fixing member and are distributed in a circumferential manner. The other ends of the first adjustable support component, the second adjustable support component, and the third adjustable support component are respectively connected to the first positioning angle steel, the second positioning angle steel, and the third positioning angle steel. The three positioning angle steels are connected to the support fixing member through the three groups of adjustable support components to form a V-shaped positioning and alignment structure.

[0009] Furthermore, the support fixing member is a hexagonal nut.

[0010] Furthermore, each group of adjustable support components includes a length adjustment screw rod, a fixed sleeve, and a limit locking mechanism. One end of the length adjustment screw rod is slidably sleeved inside one end of the fixed sleeve. The other end of the fixed sleeve is connected to the support fixing member. An opening is provided on the positioning angle steel. The other end of the length adjustment screw rod passes through the opening of the positioning angle steel and is positioned and locked by the limit locking mechanism.

[0011] Furthermore, an adjustment locking nut is installed at one end of the fixed sleeve. The length adjustment screw rod is threadedly connected to the adjustment locking nut at one end of the fixed sleeve and is sleeved inside the fixed sleeve.

[0012] Furthermore, the positioning angle steel divides the length adjustment screw rod passing through the opening into an upper threaded connection section and a lower threaded connection section.

[0013] Furthermore, the limit locking mechanism includes an upper limit locking nut and a lower limit locking nut. The upper limit locking nut and the lower limit locking nut are symmetrically distributed at intervals. The upper limit locking nut is located above the positioning angle steel and is threadedly connected to the upper threaded connection section of the length adjustment screw rod. The lower limit locking nut is located below the positioning angle steel and is threadedly connected to the lower threaded connection section of the length adjustment screw rod.

[0027] When the present utility model is specifically implemented, the plurality of groups of adjustable support components 3 include three groups of adjustable support components 3, namely a first adjustable support component 31, a second adjustable support component 32, and a third adjustable support component 33.
