Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] An embodiment of the present invention provides a shield excavating device, which is arranged on a front shield body of a shield machine. The shield excavating device includes a base, a slewing bearing, a slewing drive, a boom, a boom oil cylinder and a bucket. The fixed ring of the slewing support is fixed on the base, the tail of the boom is hinged on the movable ring of the slewing support, one end of the slewing drive device is connected to the base, and...

Abstract

The invention provides a shield excavating device and a shield machine. The shield excavating device comprises a base, a slewing bearing, a slewing driving device, a movable arm cylinder, a movable-arm cylinder and a bucket. A fixed ring of the slewing bearing is fixed on the base, the tail of the movable arm is hinged to a movable ring of the slewing bearing, one end of the slewing driving device is connected onto the base, the other end of the slewing driving device is connected to the movable ring, one end of the movable-arm cylinder is hinged to the movable ring, the other end of the movable-arm cylinder is hinged to the movable arm, and the bucket is hinged to the front end of the movable arm. Since the shield excavating device adopts the slewing bearing instead of an existing turning bearing with a sleeve structure and the slewing bearing is compact in structure and shorter, the excavating device of the shield machine can be downsized; the slewing bearing has the advantages of being able to bear larger axial and radial loads, thereby being able to bear larger excavating force.

Description

technical field [0001] The invention relates to the field of shield machines, in particular to a shield excavating device and a shield machine provided with the shield excavating device. Background technique [0002] The shield machine is a technology-intensive major engineering equipment that integrates mechanical, electrical, hydraulic, laser, sensing, measurement, control, information, computer and other technologies and is dedicated to the construction of underground tunnels. It has the functions of excavating and cutting soil, Functions such as muck transportation, tunnel lining assembly, measurement guidance and deviation correction, etc., are widely used in engineering fields such as subways, railways, highways, municipalities, and hydropower tunnels. The open shield machine is a kind of shield machine, which is mostly suitable for strata with good self-stability. The excavation device of the open shield machine is the key device for the shield machine to excavate th...
