Spring type locking mechanism of automatic pipeline all-position welder

Abstract

The invention provides a spring type locking mechanism of an automatic pipeline all-position welder, which is provided with the locking mechanism. The locking mechanism comprises a locking handle, a rear sliding block, a front sliding block push plate and a plurality of walking locking wheels, wherein the lower end of the locking handle is fixedly connected with a cam; the rear sliding block is provided with a groove, and one end of the rear sliding block is provided with a plurality of holes; the front sliding block push plate is fixedly connected with one end of a plurality of sliding bars into a whole, and a plurality of locking springs are mounted on the sliding bars; the locking handle is vertically mounted on the rear sliding block, and the cam is positioned at one end inside the groove of the rear sliding block; the front sliding block push plate is positioned in the groove of the rear sliding block, and the other ends of the sliding bars correspondingly penetrate through the plurality of holes arranged on the rear sliding block and are fixedly connected with a front sliding block into a whole; and the plurality of walking locking wheels are respectively mounted at the bottoms of the front sliding block and the rear sliding block. The invention has the advantages of simple structure, convenience for operation, great time saving of disassembly and the assembly of a welder, easy repair and maintenance, reliable locking and improved operational stability of the welder.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a spring-type locking mechanism of a pipeline all-position automatic welding machine used in the laying operation of oil and gas pipelines. It belongs to the field of machinery manufacturing. Background technique [0002] At present, the fully automatic external welding (GMAW) single-sided welding and double-sided forming technology has become the mainstream process in the welding of pipeline construction in the world. The locking mechanism of the pipeline all-position automatic welding machine is a mechanism for installing the welding machine on a special track, positioning and ensuring the stable walking of the welding machine. The locking degree of the locking mechanism will directly affect the stability and position of the welding machine, and is one of the key factors affecting the welding quality. Therefore, the locking mechanism should meet the following conditions: (1) easy assemb...

AI Technical Summary

Problems solved by technology

However, the structure of the locking mechanism is complicated, and it is difficult to repair and maintain in actual use; when the diameter of the track changes, it is necessary to adjust the connecting plate of the split bottom plate, which has poor adaptability and long adjustment operation time; it is necessary to lock two sets of eccentrics at the same time when disassembling and assembling Mechanism, very inconvenient to operate
