Abstract

The invention relates to a double-rope double-lobe leak-proof grab, which includes an upper connecting body, a left swing arm and a right swing arm, a small bucket body, a large bucket body, a support part, The left support column that is connected on the side wall of small bucket body, the right support column that is connected on the side wall of large bucket body. When the small bucket body and the large bucket body are in the open state, the left support column and the right support column are pressed against each other. Use the left support column, the right swing arm and the left support column and the right support column to support the large and small buckets to prevent the lifting rope from being stretched all the time and prolong the service life of the lifting rope 。

Description

technical field [0001] The invention relates to a double-rope and double-flap anti-leakage grab. Background technique [0002] At present, the grabbing bucket uses the lifting rope wound on the pulley block to control the opening and closing of the bucket body. The pulling force to keep it in the open state mainly depends on the left and right swing arms and the lifting rope, so the lifting rope will always be in tension. In the long run, it will cause damage to the lifting rope and shorten the service life of the lifting rope. Contents of the invention [0003] The object of the present invention is to provide a double-rope double-flap anti-leakage grab bucket with long service life. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a double-rope double-lobe leak-proof grab, which includes an upper connecting body fixedly connected with the sling of the lifting device, symmetrically arranged and the ends are all co...
