Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereby.

[0027] like Figure 1 to Figure 4 As shown, the stabilizing device of the shield machine in this embodiment includes a telescopic drive member 1 and a rectangular support shoe 2, the rectangular support shoe 2 is arranged at the working end of the telescopic drive member 1, and the rectangular support shoe 2 is normally excavated in the shield machine 9 When working, it is in an extended state and inserted into the rock-soil medium around the shield body 91 . Wherein, the long sides of the rectangular support shoes 2 are arranged along the rotation direction of the shield machine 9 , and the short sides of the rectangular support shoes 2 are arranged along the excavation direction of the shield machine 9 . It makes the force bearing area of ​​the shield machine...

Abstract

The invention provides a shield machine stabilizing device and a shield machine. The shield machine stabilizing device comprises a telescopic driving piece and rectangular support boots arranged at the working end of the telescopic driving piece; and the long edges of the rectangular support boots are arranged in the rotating direction of the shield machine, and the short edges of the rectangularsupport boots are arranged in the tunneling direction of the shield machine. The shield machine comprises a shield body and the shield machine stabilizing devices, and the shield machine stabilizing devices are symmetrically arranged on the left side and the right side of the shield body. The shield machine stabilizing device and the shield machine have the advantages that lateral rolling of the shield body is prevented, and tunneling reliability and safety of the shield machine are ensured.

Description

technical field [0001] The invention relates to the field of shield machines, in particular to a stabilizing device for a shield machine and a shield machine. Background technique [0002] Due to its good safety, economy and high efficiency, the shield machine is widely used in the construction of subways, tunnels and underground pipelines. The excavation of the shield machine relies on the rotation of the cutter head to cut the sand or rock in front of the machine into pieces. During the excavation process, the cutter head is subjected to the axial backward reaction force of the rock and soil medium and the torque opposite to the rotation direction of the cutter head. , The torque is transmitted to the shield body through the cutter head and the main drive, which makes the shield body prone to rotation during the excavation process. In severe cases, it will affect the normal operation of the shield machine and pose a safety hazard. [0003] In order to prevent and weaken t...
