A track for submerged arc welding

Abstract

The invention discloses a submerged arc welding track. The submerged arc welding track comprises a track base plate, magnetic fixing assemblies, a locking structure, a positioning unit, a positioning hole, connecting pins, connecting pin holes, a rack guide rail and a locking hole, the distance between a single track and a welding seam can be fast determined, and adjustment is facilitated; the permanent fixing assemblies are utilized and arranged on a track main body, the track can be fixed onto a steel plate, interference in track positions caused by operation of a trolley can be reduced; a locking structure is utilized and arranged at one end of the track, can be matched with a locking hole of another track to achieve tight connection of the tracks, is positioned at two ends of the track through insertion pins, and achieves tight connection and fast disassembly between two tracks. The submerged arc welding track solves the problem in aspects of low positioning speed, inaccurate positioning and non-interference and the like of existing tracks under the condition that the track weight is not increased.

Description

technical field [0001] The invention relates to the field of submerged arc welding, in particular to a track for submerged arc welding. Background technique [0002] In the process of submerged arc automatic welding straight seam welding, the stability of the track has a great influence on the welding quality. Due to reasons such as production and transportation, the track for automatic submerged arc welding generally cannot be made too long, usually only 2-5 meters long. When seam welding, only track connection can be used to achieve long weld seam welding. The common automatic submerged arc welding track laying is generally placed directly on the steel plate, and the track connection part has a male-female mating connection or a hook connection. Due to the excessive rigidity of the existing track, the other end will move when one end is adjusted during track positioning, which is not convenient for precise positioning of the track, and the positioning efficiency is low; b...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention mainly solves the following problems existing in the prior art: track laying is complicated, depends on operators, and the efficiency is low; during the use of the track, the anti-interference ability is weak, and track displacement is prone to occur; when the track is connected and used, The problem that the track parts are not tightly connected will cause fluctuations when the trolley travels here, which will affect the welding quality
