Grab Body and Diaphragm Wall Hydraulic Grab

Abstract

The invention discloses a grab body and a continuous wall hydraulic grab, and relates to the technical field of engineering machinery. It solves the technical problems of the prior art that the depth of intrusion into the working medium is relatively shallow and the grasping ability is not strong during operation. The grab body provided by the embodiment of the present invention includes a bucket body and at least one bucket tooth fixedly connected to the bucket body, wherein: the penetration angle of the bucket tooth is 60°-80°. The diaphragm wall hydraulic grab provided by the embodiment of the present invention includes a support, a hydraulic thrust mechanism, and two grab bodies provided by any one of the technical solutions of the present invention, wherein: the bucket bodies of the two grab bodies are respectively connected to the pin shaft of the support connection; the hydraulic thrust mechanism is connected with the grab body, and the hydraulic thrust mechanism can drive the two grab bodies to rotate relative to the support to a closed position or an open position. The invention can deepen the depth of the grab body intruding into the working medium when the grab body invades the working medium, and enhance the grabbing ability of the grab body to the working medium.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a grab body and a continuous wall hydraulic grab provided with the grab body. Background technique [0002] The grab body of the diaphragm wall hydraulic grab is composed of the bucket body and the bucket teeth. It is mainly divided into two stages during operation: the self-weight falling stage and the hydraulic bucket closing stage. In the self-weight falling stage, the grab body opens to the maximum angle and invades into the working medium (working medium is also called: the grabbed medium) by its own gravity; while in the hydraulic closed bucket stage, the grab body Under the action of the bucket closing torque, the bucket closing process is realized and the grasping of the working medium is completed. [0003] In the prior art, the outer contour of the bucket body of the grab body is arc-shaped (referred to as arc-shaped), and the shape of the arc-shaped buck...
