Abstract
In a tunnel boring machine designed for changing excavation tools (106) with sliding tubes (209), anchoring of load measuring elements (242) in load measuring element receptacles (236) extending in the axial direction, which are inserted in the sliding tubes (209), is provided. These load measuring elements (242) are located directly in the flux of forces introduced into the sliding tubes (209) by the excavation tools (106) and remain in place during a change of excavation tools (106) after an initial installation and subsequent calibration. This allows the loads acting on the excavation tools (106) to be detected in a less complex and long-term stable manner.

A tunnel boring machine having a number of sliding tube units, each with a sliding tube flange (215), with a sliding tube bearing ring (212) and with a sliding tube (209) which is connected to the sliding tube flange (215) and to the sliding tube bearing ring (212) and in which one excavation tool (106) is displaceably mounted for a tool change, and having at least one load measuring element (242) which is configured to measure loads exerted on excavation tools (106), wherein at least one load measuring element receptacle (236) extending in the axial direction is designed in at least some sliding tubes (209), that the or each load measuring element receptacle (236) is designed in a blind hole manner and that a load measuring element (242) is arranged in at least one load measuring element receptacle (236).
A tunnel boring machine comprising:
- sliding tube units, each having:
- a sliding tube (209) extending between and connected to both a sliding tube flange (215) and a sliding tube bearing ring (212), and
- one excavation tool (106) displaceably mounted for a tool change within the sliding tube (209), wherein at least one sliding tube (209) includes an axially extending, blind receptacle (236) for receiving a load measuring element (242) for measuring loads exerted on the excavation tool (106) associated with the sliding tube (209) having the receptacle (236).
