Welding carriage control system for continuous welding technology

Abstract

A welding carriage control system for a continuous welding technology comprises a DSP controller, a motor drive circuit and a welding carriage, wherein the welding carriage comprises a frame body (8), a front axle (61) and a rear axle (51); the frame body (8) is used for bearing a welding gun (9); front wheels (6) are fixedly mounted on the front axle (61) which is rotationally connected with the frame body (8); rear wheels (5) are fixedly mounted on the rear axle (51) which is rotationally connected with the frame body (8); a front axle first one-way bearing (62) and a front axle second one-way bearing (63) with opposite rotatable directions are mounted on the front axle (61) in the axial direction in a spaced manner; a rear axle first one-way bearing (52) and a rear axle second one-way bearing (53) with opposite rotatable directions are mounted on the rear axle (51) in the axial direction in a spaced manner; a front drive wheel (111) is arranged on the front axle (61) and is in power connection with a driving wheel (101), driven by a motor, through a front driving belt (211); a rear drive wheel (121) is arranged on the rear axle (51).

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding trolley control system for continuous welding technology. Background technique [0002] In the field of welding, especially in the continuous welding process, it is often necessary to use a welding trolley attached with a welding torch to continuously weld the weld seam. Due to the different shapes of the weld seam of the workpiece, the welding trolley may experience a horizontal route segment, an uphill route segment with a forward inclination angle or a downhill route segment with an inclination angle during operation. In each route segment, the welding carriage can perform forward and reverse travel directions. [0003] However, due to the existence of these slopes, it may interfere with the control of the running speed of the welding trolley. Moreover, when the slope is large, accidental loss of power of the welding trolley may cause accidents such as slipping. ...

[0003] However, due to the existence of these slopes, it may interfere with the control of the running speed of the welding trolley

Moreover, when the slope is large, the accidental loss of power of the welding trolley may cause accidents such as slipping

When the slope is small, the acceleration due to the influence of gravity may also interfere with the speed of travel
