Problems solved by technology

Due to the limitations of the traditional dredging grab structure design, after the dredging operation is completed, the surface of the seabed or riverbed is uneven
Nowadays, many engineering operations such as marine engineering and waterway engineering have put forward high requirements for the flatness of the seabed. The traditional dredging grab excavation operation can no longer meet the requirements for the flatness of the seabed or riverbed.

Abstract

The invention relates to a brace rod sliding groove type hydraulic flat digging grab bucket which comprises an upper bearing beam, a lower bearing beam and a bucket body. The upper bearing beam is connected with the lower bearing beam through an open and closed bucket oil cylinder, the bucket body is hinged to the lower bearing beam, the upper bearing beam is provided with a brace rod sliding unit, the brace rod sliding unit comprises a brace rod sliding oil cylinder and a brace rod, one end of the brace rod is hinged to the bucket body, and the other end of the brace rod is connected with the brace rod sliding oil cylinder. The brace rod sliding groove type hydraulic flat digging grab bucket further comprises a hydraulic control device, and the hydraulic control device controls work of the open and closed bucket oil cylinder and the brace rod sliding oil cylinder. The brace rod sliding groove type hydraulic flat digging grab bucket has the advantages that the brace rod sliding groove type hydraulic flat digging grab bucket is simple in structure and convenient to operate, an excavated seabed or river bed can be flattened so as to meet the flatness requirements in engineering operation, the maximum opening and the maximum excavating depth of the grab bucket can be changed conveniently, the operation requirements of different working conditions can be met, and popularization and application values are large.

Description

technical field [0001] The invention relates to a grab bucket used in underwater excavation operations such as dredging projects, in particular to a brace chute type hydraulic horizontal digging grab bucket. Background technique [0002] At present, grab dredgers are widely used in dredging of major ports, seabed or riverbed dredging and other fields. The dredging grab used by the dredger is the main pick-up device for dredging operations. Its structure mainly includes upper bolster, lower bolster, strut, bucket body, wire rope and pulley. Due to the limitations of traditional dredging grab structure design, after the dredging operation is completed, the surface of the seabed or riverbed is uneven. Now many engineering operations such as marine engineering and waterway engineering have put forward high requirements on the flatness of the seabed, and the traditional dredging grab excavation operations can no longer meet the requirements for the flatness of the seabed or rive...
