Abstract

The invention discloses a welding mechanism with a bidirectional locking mechanism, mainly comprising a trolley locking mechanism (1) and a trolley walking mechanism (2), wherein a motor shaft gear (29) in the trolley walking mechanism (2) is mutually meshed with an intermediate gear (21); an intermediate gear B (22) is meshed with a driving gear (27) which is meshed with a guide rack (32); front driving wheels (26) are respectively arranged on the left side and the right side of a front driving shaft (31) and rear driven wheels (35) are respectively arranged on the left side and the right side of a rear driving shaft (33), thereby forming a main body of the trolley walking mechanism (2); a compression shaft (14), a cone-shaped compression wheel (15), a sliding block (12), a stop block (10) and a locking wheel (11) form the locking mechanism (1); and the compression of the compression wheel (15) on the side of a guide rail (3) can be realized by rotating the compression shaft (14) and the locking wheel (11). The invention has the advantages of simple structure, smallness, flexibility, reliable work, low construction cost and simple and easy maintenance and repairing.

Description

technical field [0001] The invention relates to a structure of a welding trolley, in particular to a track all-position welding trolley equipped with a bidirectional locking mechanism. Background technique [0002] The guide rail all-position welding robot is a type of welding robot that performs welding operations along the guide rail. Its running track is relatively fixed and its movement repeatability is good. It is suitable for welding regular welds. The welding trolley is the driving mechanism to realize the automatic welding process. It is installed on the welding guide rail and moves along the pipe wall with the welding torch. It is one of the important links to realize the automatic welding of the groove. The all-position welding of the pipeline requires the welding trolley to move along the circular weld seam for a whole circle, and the welding trolley crawls smoothly on the pipe along the guide rails to obtain high-quality weld seams. In order to achieve smooth cr...
