Description

Technical Field

[0001] This utility model relates to an overload protection device for a slag pusher, belonging to the field of welding slag pusher technology. Background Technology

[0002] Currently, most slag pushing mechanisms directly control a fixed slag pusher to push slag in a single direction. Some lack effective ventilation systems, and the exhaust gas generated after cutting is not treated. The application of sensors is also limited. To meet slag pushing requirements, many use higher-power motors, resulting in relatively higher size and cost. The buckets are mostly fixed. To prevent them from hitting uneven ground during operation, the lower edge of the bucket needs a certain distance from the ground. This leads to either incomplete slag removal or repeated contact between the lower edge of the bucket and protruding ground, potentially damaging the bucket. Additionally, small pieces of slag may get stuck behind or below the bucket during slag pushing. In such cases, the bucket may carry slag and wear down the channel during movement, or return to its parking position with slag, requiring manual cleaning. Furthermore, since the slag pushing mechanism is driven by a motor, when there is more slag than designed, the mechanism cannot push it. This can lead to motor overload or damage to the sprockets and chains due to insufficient torque. Utility Model Content

[0005] The top of the slag pushing support is equipped with a duct baffle pusher, the middle of which is fixedly mounted on the slag pushing support. Both ends of the duct baffle pusher are downwardly curved arc structures. Two connecting plates are provided on the lower side of the middle of the duct baffle pusher. The two connecting plates are respectively hinged to hinge seats fixed to the slag pushing support. The two hinge seats are respectively fixed to two longitudinal beams of the slag pushing support, and the two hinge seats are located on different sides of the two longitudinal beams. A stroke sensor is provided on the other side of the longitudinal beam opposite to the hinge seat. A through hole is provided transversely on the longitudinal beam between the hinge seat and the stroke sensor. When the connecting plate rotates with the duct baffle pusher around the hinge point between it and the hinge seat, the connecting plate can pass through the through hole to trigger the stroke sensor.

[0006] Furthermore, the slag pushing plate is located on the front side of the slag pushing support. Sleeves are fixedly installed on the upper sides of both ends of the slag pushing support.
