Abstract

The invention discloses an adaptive adjustment device for complex terrain of a tunnel shield machine, comprising: a shield support and an excavator, the excavator is installed on the shield support, and an extraction structure and a shock-absorbing transport screen are installed in the shield support Sub-structure, the extraction structure is installed on the shield support through the shock-absorbing structure. The external force generated during the operation of the device is consumed by several shock-absorbing sleeve springs in the horizontal direction and several shock-absorbing spring columns through the shock-absorbing structure, and the sand and gravel are shock-absorbed and transported through the shock-absorbing transportation screening structure , avoiding the phenomenon of leakage during transportation, and avoiding the phenomenon of external force shaking during operation.

Description

technical field [0001] The invention relates to the technical field of shock absorption of shield machines, in particular to an adaptive adjustment device for complex terrain of tunnel shield machines. Background technique [0002] The shield machine is a major equipment for tunnel construction such as railways, highways, water conservancy, and municipal construction. Its rock-breaking efficiency and advancing speed have attracted much attention. However, the shield machine vibrates violently during shield construction, causing its internal key components to be damaged due to excessive dynamic stress, resulting in parts replacement and downtime accidents, and the internal equipment is prone to transportation difficulties. In view of this, in view of the above After in-depth research on the problem, this case came into being. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems by designing an adaptive adjustment d...
