Problems solved by technology

Although the external counterparts currently on the market are simple in structure, on the one hand, they have a certain resistance to the welder's operation during use, and on the other hand, they cannot be adjusted axially, and the applicable pipe diameter is also relatively single.
[0005] Chinese patent document CN106826080B discloses "A Pipeline Welding External Mouth", which can realize the functions of axial adjustment and automatic welding. When the change is large, it takes a long time to twist the adjusting bolt, and the work efficiency is low. The rotating block on the gear ring will be jammed and shaken due to friction, which will affect the welding quality and other problems.
In addition, in this patent, since the adjusting bolts do not rotate synchronously, it is easy to appear that the oil pipeline adjusted to the final adjusting ring is not in the center of the adjusting ring, so that the axial fine-tuning nut is not aligned due to the bolts on both sides when adjusting. However, the additional torque affects the axial adjustment and the life of the connecting thread

Embodiment 1

[0040] like figure 1 , figure 2 , image 3 and Figure 12As shown, the oil pipeline counterpart for auxiliary automatic welding includes an adjusting ring 1, a fixing ring 2, an axial adjusting rod 3 and a gear ring 4, the adjusting ring 1 is composed of an upper adjusting ring 101 and a lower adjusting ring 102, and the fixing ring 2 It consists of an upper fixing ring 201 and a lower fixing ring 202. The adjusting rod 3 includes a first bolt 301 and a second bolt 303. The fixing ring 2 is provided with a number of limit grooves 206. The adjusting ring 1 and the fixing ring 2 are both distributed with circular arcs. brace 304, and the arc brace 304 on the adjusting ring 1 is connected with the second bolt 303, the arc brace 304 on the fixed ring 2 is connected with the first bolt 301, and the first bolt 301 and the second bolt 303 are passed through the axial fine-tuning nut 302 connection, which is characterized in that: the upper adjustment ring 101 is distributed with ...

Embodiment 2

[0048] Such as Figure 4~6 As shown, the difference between this embodiment and Embodiment 1 is that the quick adjustment mechanism includes an adjustment sleeve 105 and an adjustment bolt 106 . The adjusting bolt 106 is threadedly connected with the adjusting sleeve 105 , and a pair of positioning heads 110 are arranged on the outer surface of the adjusting sleeve 105 . The adjustment base 104 is provided with a through hole 107, and the through hole 107 has a pair of guide grooves 108 matched with the positioning head 110 in the axial direction. The communicating annular groove 109 is provided with a pair of limit stoppers 111 inside the annular groove 109 .

[0049] When in use, first turn the adjusting sleeve 105 to slide the positioning head 110 to the position of the guide groove 108, then twitch the adjusting sleeve 105 to slide the adjusting sleeve 105 in the through hole 107 on the adjusting base 104 to achieve quick adjustment of the adjusting bolt 106. The purpose...

Embodiment 3

[0052] Such as Figure 7 As shown, the T-shaped slot 103 is connected with a main slider 118 through a T-shaped slider 116, and the main slider 118 is threaded with a feed adjustment rod 112. Adjusting the feed adjustment rod 112 can adjust the length of the inspection needle 114. Adapt to different pipe diameters. One end of the feed adjustment rod 112 located in the main slider 118 is flexibly connected with the second return spring 113, the second return spring 113 is fixedly connected to the check pin 114, and the end of the check pin 114 away from the second return spring 113 is provided with a There is a cam 115 which reduces the friction at the tip of the test pin 114 . A scale 117 is also provided on the heart-testing needle 114, which is convenient for judging the position change.

Abstract

The invention discloses a petroleum pipeline mouth aligner capable of assisting automatic welding. The petroleum pipeline mouth aligner comprises a regulating ring, a fixed ring, an axial regulating rod and a gear ring, wherein the regulating ring is composed of an upper regulating ring and a lower regulating ring; the fixed ring is composed of an upper fixed ring and a lower fixed ring; the regulating rod comprises a first bolt and a second bolt; a plurality of limiting slots are formed in the fixed ring; the regulating ring and the fixed ring are uniformly distributed with circular-arc supports, and are separately connected to a first bolt and a first bolt; and the first bolt and the second bolt are connected through an axial fine tuning nut.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a petroleum pipeline counterpart for auxiliary automatic welding. Background technique [0002] The oil pipeline system, that is, the pipeline system used to transport oil and petroleum products, is mainly composed of oil pipelines, oil stations and other auxiliary related equipment. For transportation equipment, compared with railway and highway oil transportation, which are also land transportation methods, pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high safety factor. [0003] Oil pipelines must use a certain link to form a complete system. There are three main types of pipe connection methods: threaded, welded and flanged. For lines with high pressure and strict sealing requirements, welding is basically used. When welding the pipes, it is necessary to use a counterpart in advance to ensure the stab...
