Shear type leakproof grab bucket

Abstract

The invention relates to a shear type leakproof grab bucket, which is particularly used for a crane to load and unload cargos, belonging to the technical field of crane equipment. The shear type leakproof grab bucket mainly comprises a leakproof bucket body, a lifting frame, chains, a left grab bucket arm, a right grab bucket arm, an upper pulley block and a lower pulley block, wherein lifting ropes are connected to the upper sides of both ends of the lifting frame; the chains are connected to the lower sides of both ends of the lifting frame; the lower ends of the chains are connected with both sides of the leakproof bucket body; the left grab bucket arm is hinged with the right grab bucket arm through a central pin; and the left grab bucket arm and the right grab bucket arm are provided with the upper pulley block and the lower pulley block respectively. The shear type leakproof grab bucket has a simple, compact and reasonable structure; the leakproof bucket body has a good leakage-proof effect; the closing and opening moment is not reduced in the closing and opening process that the grab bucket grabs materials; the track of a bottom cutting edge of the grab bucket approximates to a straight line when the grab bucket grabs materials; and the shear type leakproof grab bucket has light self weight and large grabbing ratio, and greatly improves the loading and unloading operation efficiency.

Description

technical field [0001] The invention relates to a scissor-type anti-leakage grab, in particular to a crane for loading and unloading goods, and belongs to the technical field of crane equipment. Background technique [0002] In the prior art, the opening of the jaws of the general double-jaw grab bucket is limited, the closing moment of the grab is getting smaller and smaller during the closing process, and the trajectory formed by the jaw edge in the cargo is arc-shaped. Its shortcoming is that the horizontal area occupied by the grab bucket is too small when it is opened to grab the goods, so when grabbing the goods with a small proportion, the amount of grabbing is too small, and it is easy to damage the bottom of the storage container, such as the bottom of the cabin, the cargo The bottom of the field, etc. The work efficiency is low and cannot meet the work needs. [0003] In the loading and unloading of bulk goods such as bulk grain, bulk chemical fertilizer, and bul...

Problems solved by technology

Its shortcoming is that the horizontal area occupied by the grab bucket is too small when it is opened to grab the goods, so when grabbing the goods with a small proportion, the amount of grabbing is too small, and it is easy to damage the bottom of the storage container, such as the bottom of the cabin, the cargo the bottom of the field, etc.

Not only waste a lot of goods, but also seriously pollute the environment

Therefore, solving spills in cargo handling is a very difficult and pressing issue.
