Problems solved by technology

[0008] It can be seen from the above-mentioned working process that the impact force of the grab bucket 11 on the ground directly affects the working efficiency of the grab bucket 11, while in the prior art, the impact on the ground is achieved by the gravity of the grab bucket 11 and other components. The impact force is limited, which limits the working efficiency of the diaphragm wall grab

Abstract

The invention discloses a continuous wall grab which comprises a guide frame (21), a power lift component, a guide device (24) and an impact component (26), wherein the guide frame (21) is connected with a grab (22); one end of the power lift component is connected with the guide frame (21), and the other end of the power lift component is connected or disconnected with the impact component (26); one of the impact component (26) and the guide device (24) is provided with a slide channel, the other one is provided with a slide rail, and the slide channel and the slide rail are mutually matched; and the two ends of the guide device (24) are respectively connected with the power lift component and the grab (22), so that the impact component (26) acts on the grab (22) along the guide device (24). The continuous wall grab disclosed by the invention can provide high ground impact forces for the grab, and has high operating efficiency.

Description

Technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a continuous wall grab. Background technique [0002] Diaphragm wall grab is an important machine for the construction of underground continuous wall grooves. It is a kind of construction machinery equipment that implements grooving work through a wire rope suspension grab device. With the increase of construction projects, the application of diaphragm wall grabs is increasing. more. [0003] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a typical continuous wall grab bucket in the prior art. [0004] The main working parts of the continuous wall grab include the suspension mechanism (including the mast 1, the wire rope 13 and the main winch 15 shown in the figure), the guide mechanism 14, the correction mechanism (not shown in the figure), and the grasping mechanism (including the The grab 11 shown in the figure) and the deviation measuring s...
