Translation-type flat-digging grab bucket

Abstract

The invention relates to a translation-type flat-digging grab bucket, in particular to a grab bucket used in the digging fields such as the field of dredgers. The translation-type flat-digging grab bucket comprises a grab bucket base and a pair of jaw plates, wherein the pair of jaw plates are respectively articulated with the grab bucket base, and the digging action can be realized by the opening and closing of the jaw plates; the translation-type flat-digging grab bucket is characterized in that four guide sliding grooves are horizontally arranged at the side of the grab bucket base, are arranged up and down in pairs and are in bilateral symmetry; each guide sliding groove is internally provided with a roller wheel; and the pair of jaw plates are respectively articulated with the two adjacent upper and lower roller wheels so as to do translation along the guide sliding grooves by virtue of the roller wheels. Due to the arrangement of the guide sliding grooves on the grab bucket base, the jaw plates can always do translation along the guide sliding grooves by virtue of the roller wheels arranged in the guide sliding grooves, and the translation-type flat-digging grab bucket is simpler, more convenient and lower in cost compared with the traditional way in which accurate control is used to realize flat digging; furthermore, a structure of the guide sliding grooves is reliable in running and high in safety, so that the translation-type flat-digging grab bucket is suitable for operation underwater and in other complicated environments.

Description

technical field [0001] The invention relates to a grab bucket used in excavation fields such as dredgers, in particular to a translational horizontal digging grab bucket. Background technique [0002] At present, the grabs equipped on the dredgers are not horizontal digging grabs. After excavation, there will be small tips that cannot be caught by the grabs on the river bed, which is not conducive to the smoothness of the river bed. Theoretically, horizontal excavation can be achieved by controlling the retraction and release of the wire rope, which requires extremely precise control. However, the grabs used by large machinery such as dredgers have a large mass, and the motors used are all high-power. It is very difficult to achieve precise control. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a translational excavation grab, which can use the guide chute to realize the translational movement of the tooth tip...
