In this application, the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. These terms are used primarily to better describe the invention and its embodiments, and are not intended to limit the indicated devices, elements or components to a particular orientation or to be constructed and operated in a particular orientation.

Moreover, some of the above terms may be used to indicate other meanings besides the orientation or positional relationship, for example, the term "on" may also be used to indicate some kind of attachment or connection relationship in some cases. The specific meaning of these terms in the present invention can be understood by those of ordinary skill in the art as appropriate.

Furthermore, the terms "mounted," "disposed," "provided," "connected," and "sleeved" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1, 2 and 4, the present application relates to a core retaining device for a tunnel boring machine, the device mainly comprises a top shaft 1, a core taking drill pipe 3, a water braid 4, a power head output shaft 2, a core jacking oil cylinder 5, a power head box 6, a linear sliding table module 7 and a roller bracket 8, wherein the roller bracket 8 is fixedly installed on the linear sliding table module 7 to support the core taking drill pipe 3; the water braid 4 is arranged on the coring drill pipe 3 and transmits power, water or compressed air to the coring drill pipe 3 so as to discharge slag, cool and lubricate the coring drill pipe 3; the rear end of the coring drill pipe 3 is arranged on a power head output shaft 2 of a power head box body 6; the apical axis 1 passes simultaneously and gets core drill pipe 3 and unit head output shaft 2, and fixed mounting is on apical axis hydro-cylinder 5, and apical axis 1 end is equipped with fluting disc 101 to realize getting core drill pipe 3 to the support of apical axis 1, apical axis hydro-cylinder 5 fixed mounting realizes the promotion to apical axis 1 on sharp slip table module 7, unit head box 6 is installed on sharp slip table module 7's slip table, realizes along with sharp slip table module 7's slip table synchronous slip.
