Description

Automatic slag pushing system of large cutting table TECHNICAL FIELD

[0001] The present application relates to an automatic slag pushing system of a large cutting table, belonging to the technical field of welding slag pushing. BACKGROUND

[0002] At present, most of the slag pushing mechanisms directly control the fixed slag pushing vehicle to perform the slag pushing operation in a single direction, some of which do not have an effective exhaust system, and the exhaust gas generated after cutting is not treated. At the same time, the application of sensors is also very little. In order to meet the requirements of slag pushing, a larger power motor is often used in many cases, resulting in relatively high size and cost. The bucket is basically fixed, in order to avoid being knocked by uneven ground during operation, the lower edge of the bucket needs to be away from the ground by a certain distance, which causes the bucket to be either not clean or the lower edge of the bucket to repeatedly contact the protruding ground, which may damage the bucket. At the same time, small pieces of slag may be stuck behind or below the bucket in special circumstances when the bucket is pushing slag. In this case, the bucket will wear out the passage with the slag during movement, or bring the slag back to the parking position, which can only be cleaned by manual work.

[0003] In addition, the existing slag pushing mechanism adopts a tank chain type or a cable type scheme. The tank chain type has difficulty in maintenance and replacement in the later stage, and has high subsequent maintenance cost. The cable type has the problem of cable friction with the ground, which causes the surface of the cable to wear out and poses a safety risk. Among them, the slag pushing mechanism is driven by a motor to move forward. When there is more slag than the design requirement, the slag pushing mechanism cannot push the slag. At this time, the motor may be overloaded or the chain wheel and chain may be damaged due to unable to withstand the torque. SUMMARY
