Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0026] Such as figure 1 As shown, at the connection between the TBM cutter head 15 and the TBM front bracket 16, the slip ring mover body 1 of the power supply device is fixedly connected to the TBM cutter head 15 through screws, and the outer slip ring stator body 2 is connected to the TBM front bracket 16 through screws. Fixed connection. The inner slip ring stator body 17 is fixedly installed on the outer slip ring stator body 2 by screws 18 . The rotary joint is connected and installed in the oil channel hole 19 at the rear end of the slip ring mover body 1 through the bolt 30 on the mandrel flange ( image 3 , Figure 5 shown), the required installation space is small, and the sealing performance is reliable.
[0027] Such as figure 2 As shown, the slip ring mover body 1 is supported on the outer slip ring stator body 2 and the inner slip rin...

The invention relates to a TBM-mounted integrated junction device of an advance geological detection instrument. When a TBM rotates and operates, the integrated junction device rotates along with the TBM; when the TBM stops rotating and operating, the integrated junction device is in charge of supplying power and oil to detection equipment, conducting data transmission and controlling communication, so that conditions are provided for the implementation of advance geological work; besides, the occupied space is not large, and the leakproofness is good. A double-stator conducting sliding ring is arranged between a TBM cutter disc and a TBM front support, wherein the double-stator conducting sliding ring comprises a sliding ring rotor fixedly connected with the rotary cutter disc, an outer sliding ring stator fixedly connected with the TBM front support and arranged on the outer side of the sliding ring rotor in a sealed and sleeved mode, and an inner sliding ring stator fixedly connected with the outer sliding ring stator and arranged on the inner side of the sliding ring rotor in a sealed and sleeved mode, the inner sliding ring stator and the outer sliding ring stator are respectively provided with a bush gear, the bush gears are electrically connected with corresponding slide way devices of the sliding ring rotor, the bush gears, the slide way devices and the detection equipment are connected through wires for transmission of currents and signals, and a multi-channel rotating joint is connected into an oil supply hole in the rear end of the sliding ring rotor in a sealed mode.
Description
technical field [0001] The invention relates to an integrated wiring device of an advanced geological detection instrument installed in a TBM of a tunnel hard rock boring machine, which provides power supply, data transmission channel and hydraulic oil for geological advanced prediction detection equipment, and belongs to the field of geological exploration equipment. Background technique [0002] There are two main methods of tunnel construction: the drill and blast method and the tunnel boring machine construction method. Among them, the tunnel boring machine construction method has the advantages of "fast construction speed, good quality, safety and environmental protection". In the tunnel powerhouses such as the United States, Japan, and Europe, the tunnel boring machine construction method occupies a dominant position. Generally, tunnels over 3 kilometers must use tunnel boring machines. Tunneling machine construction method. However, the adaptability of the tunnel bor...
