2. Equipment Introduction

2.1 Equipment Usage

This equipment is suitable for cleaning aluminum slag that falls into deep wells during the casting process. By combining the up and down movement of the crane hook with the opening and closing structure inside the grab through mechanical means, the opening and closing of the grab can be achieved, and the deep well aluminum slag can be cleaned, greatly reducing manual labor, providing work efficiency, and ensuring safety and reliability.

2.2 Workflow of Single Rope Grab

1. The lifting ring is installed on the crane hook, and when the grab bucket is opened, due to gravity, the pulley descends and the protrusion is pushed at an angle of about 30 ° by the ejector pin.

2. Lift the steel wire rope, and the entire sliding block moves up along the guide rail. After moving a small distance, the protruding block connects with the groove, driving the entire support beam to move up, completing the grab bucket to close and grab the material.

3. When unloading, release the steel wire rope. At this time, the bottom of the grab bucket first contacts the support surface. Due to gravity, the slider moves down and the protrusion is pushed horizontally by the ejector pin (the grab bucket is not opened)

4. Lifting the steel wire rope, the slider moves upward, and the protruding mechanism is blocked by the groove to a vertical position, located on both sides of the guide rail. As a result, the pulley moves away from the lower constant beam and moves upwards to connect with the upper support beam. At the moment when the grab bucket leaves the ground, due to the weight effect, the grab bucket opens for unloading.

5. After unloading, the grab bucket is in an open state in the air and placed on top of the material. The sliding block descends, and the cam is pushed at an angle of about 30 ° by the ejector pin, completing a grab bucket process.

3. Main components and structural performance of the equipment

3.1 Equipment Composition: A single rope grab bucket is a commonly used type of grab bucket in cranes, consisting of a lifting beam (ring), steel wire rope, sliding rod, upper bearing beam, sliding frame group, lower passenger beam, support rod, bucket body, etc. (as shown in the figure below). The single rope grab mainly relies on the interaction between the trickle block, convex block, groove, and top pin of the grab to complete the unloading process.
