Integral type shield cutterhead driving device

Abstract

The invention discloses an integral type shield cutterhead driving device, comprising at least one motor, a pinion, a large bearing, a stress ring, an outer seal seat, an outer seal ring, a plane seal, and the like, wherein the driving device also comprises a plurality of parallel passages, a pipeline penetrates through each passage, and a pipeline seal ring is arranged between the passage and the pipeline; and the passage penetrates through a bearing outer ring of the entire large bearing and partially or completely or does not penetrate through the outer seal seat, or just partially penetrates into the bearing outer ring of the large bearing so as to selectively input or output lubricant grease or cooling water on the front ends and the rear ends of the outer seal ring, a bearing inner ring and the bearing outer ring by transference. The integral type shield cutterhead driving device of the invention adopts the sequential steps of preassembling each component and a grease pipeline or a cooling water pipeline into an integral type shield cutterhead driving device and installing the integral type shield cutterhead driving device in a shield casing, thereby saving the resources of materials and time and enabling the space utilization rate to be high.

Description

technical field [0001] The invention relates to a cutterhead drive device installed in a shield machine casing, in particular to an integral shield cutterhead drive device. Background technique [0002] At present, shield tunneling technology at home and abroad has developed to a relatively high level, and shield construction has obvious advantages such as speed, high quality, economy, and safety. Taking the subway shield as an example, the tunnel diameter of each project is different. For example, the outer diameter of the Shanghai subway tunnel segment is 6.2m, the outer diameter of the Beijing subway tunnel segment is 6m, and the outer diameter of the foreign subway tunnel segment is 5.8m. , 6.3m, 6.7m, 7m and other specifications, the diameters of the shield machine shells required are different. The cutterhead driving device is one of the most important and critical parts in the shell of the shield machine, and the processing and installation of the cutterhead driving ...

AI Technical Summary

Problems solved by technology

In the prior art, shield machine shells with different diameters are installed with basically the same cutter head drive device, which will inevitably result in the cost of the number of resources for the cutter head drive device, as well as the cost of man-hours due to the assembly of parts one by one on site.
