Description

Anti-spilling grab bucket and driving method thereof

Technical Field

The invention relates to the technical field of grab buckets, in particular to a grab bucket capable of preventing scattering and a driving method thereof.

Background

The grab bucket is a special tool for grabbing dry and scattered goods by a crane. Two or more openable bucket-shaped jaws are combined together to form an object containing space, the jaws are closed in a material pile during loading, materials are grabbed into the object containing space, the jaws are opened in a suspended state above the material pile during unloading, the materials are scattered on the material pile, and the opening and closing of the jaws are generally controlled by a steel wire rope of a crane hoisting mechanism. The grab bucket operation has no heavy physical labor, can achieve higher loading and unloading efficiency and ensure safety, and is a main dry bulk cargo loading and unloading tool for ports. According to the kind of the operation goods, the operation goods can be divided into an ore grab bucket, a coal grab bucket, a grain grab bucket, a wood grab bucket and the like.

The grab bucket comprises a hydraulic grab bucket and a mechanical grab bucket, wherein the hydraulic grab bucket is provided with an opening and closing structure and is generally driven by a hydraulic oil cylinder, and the hydraulic grab bucket consisting of a plurality of jaw plates is also called as a hydraulic claw. The hydraulic grab bucket is widely applied to hydraulic special equipment, such as a hydraulic excavator, a hydraulic lifting tower and the like, the mechanical grab bucket is not provided with an opening and closing structure, is usually driven by external force of a rope or a connecting rod, can be divided into a double-rope grab bucket and a single-rope grab bucket according to the operation characteristics, and is most commonly used as the double-rope grab bucket.

In the process of selecting the grab bucket, the power form of the grab bucket is selected according to the crane. According to the definition of the grab bucket: the grab bucket is a fetching device under the crane, so even the most advanced grab bucket can independently complete work without leaving the crane. On the contrary, the ship unloader with the advanced position and the large tonnage can not leave the grab bucket, so that the production efficiency is high. Therefore, what crane should be equipped with what grab bucket, cannot be used when the grab bucket is mistakenly equipped, and cannot be used when the grab bucket is overloaded. For example: the hoisting drum of the crane is single, and only a single rope grab bucket can be matched if a mechanical grab bucket is matched, and the grab bucket cannot work if a four-rope grab bucket is matched.

In the process of using a traditional mechanical grab bucket, due to the existence of an adjusting plate in the grab bucket, a gap exists between two grab bucket bodies, and then the situation that the grab bucket scatters when grabbing articles of chip types such as broken stones can occur is achieved.
