Problems solved by technology

[0002] For the installation of large-diameter metal pipes, due to its relatively heavy weight, it is difficult to install. In the past, the seam adjustment before welding was carried out by cranes or gantry cranes and differential hoists.
However, the crane is convenient, but it is limited by the site, and the fine-tuning is relatively difficult, and the cost of using the crane is relatively high
And the gantry crane plus the differential hoist to hoist is relatively cumbersome, and the labor intensity of the workers is relatively high.

Embodiment Construction

[0022] The technical solutions of the present invention will be further described below through the accompanying drawings and embodiments.

[0023] Such as Figure 1 to Figure 3 As shown, the pipeline welding auxiliary matching device of the present invention includes a relatively flat beam 1, a pressure rod booster mechanism 2, a first pipeline clamp 3, a second pipeline clamp 4 and a third pipeline clamp 5 and consists of five parts. The specific structure and connection method are as follows:

[0024] The flatter beam 1 is placed on the installed pipeline, and a part is hung out to lift the pipeline to be welded. The pressure rod booster mechanism 2 is composed of a pressure rod 6 and a strut 7, the depression rod 6 is connected to the flatter beam 1 through a hinge, the middle of the depression rod 6 is hinged with one end of the strut 7, the other end of the strut 7 is connected to the Slider 12 is hinged. The first pipeline clamp 3 includes two clamp arms 8 , one end ...

Abstract

The invention provides an assisted butt joint device for pipeline welding. The assisted butt joint device comprises a flat beam, a pressing rod boosting mechanism, a first pipeline clamp, a second pipeline clamp and a third pipeline clamp; a specific structure and a connection relation are as follows: the first pipeline clamp and the second pipeline clamp are fixedly arranged on the flat beam; the third pipeline clamp, which can move along the flat beam, sleeves the right side of the flat beam; the pressing rod boosting mechanism is hinged to the flat beam and a slide block respectively and is used for boosting the third pipeline clamp so as to realize axial movement. By adopting the assisted butt joint device for the pipeline welding, vertical and axial adjustment in a butt joint process can be realized, and rapid alignment and rapid butt joint and welding are realized; the assisted butt joint device has the advantages of high efficiency, economical efficiency and labor saving and simplicity and convenience for operation.

Description

technical field [0001] The invention relates to the technical field of pipeline installation, in particular to an auxiliary matching device for pipeline welding, which is mainly used for large-scale pipeline installation. Background technique [0002] For the installation of large-diameter metal pipes, due to their relatively heavy weight, the installation is relatively laborious. In the past, the seam adjustment before welding was carried out by cranes or gantry cranes and differential hoists. However, although the crane is convenient, it is limited by the site, and the fine-tuning is relatively difficult, and the cost of using the crane is relatively high. However, the gantry crane plus the differential hoist is relatively cumbersome for hoisting, and the labor intensity of the workers is relatively large. [0003] In view of the above problems, it is of great significance to study a large-scale pipeline welding auxiliary matching device to realize longitudinal and axial ...
