Problems solved by technology
[0003] In order to facilitate the use of the shield machine in the harsh tunnel environment, in the prior art, the rotary cutter head and the limit frame are installed by multiple clamping methods to provide stability for the shield machine. However, the shield machine uses When installing in the way of clamping, since most of the rotary cutterhead and the limit frame of the shield machine are made of metal, there is a certain gap between the metal and the metal when the rotary cutterhead and the limit frame are clamped. gap, and there is a certain degree of sliding between the metals, resulting in low stability caused by clamping, which is not conducive to the construction of the tunnel by the shield machine

The invention provides a stabilizing mechanism of a shield tunneling machine and the shield tunneling machine. The stabilizing mechanism of the shield tunneling machine comprises a limiting frame and a rotary cutter head, the limiting frame is connected with the rotary cutter head in a clamped mode, clamping blocks are fixedly connected to the side, close to the limiting frame, of the rotary cutter head, the two clamping blocks are symmetrically arranged on the outer surface of the rotary cutter head, the outer surface, away from the clamping blocks, of the rotary cutter head is fixedly connected with a cutter block, a clamping opening is formed between the upper end and the lower end of the limiting frame, and each clamping block is connected with the corresponding clamping opening in a clamped mode. Through arrangement of a first pushing block, a second pushing block and an elastic block, when the limiting frame and the rotary cutter head in the shield tunneling machine are installed in a clamped mode, the stability of clamping the limiting frame and the rotary cutter head can be further improve, meanwhile, through arrangement of an extrusion plate and an oil control plate, lubricating oil can be accurately added to a rotating shaft, the flexibility of the shield tunneling machine is improved, the problem that the rotating shaft is rusted due to insufficient contact between the lubricating oil and the rotating shaft is solved, and therefore, the stability of the shield tunneling machine is further improved to a certain extent.
Description
technical field [0001] The invention relates to the technical field of shield machine manufacturing, in particular to a stabilizing mechanism of a shield machine and the shield machine. Background technique [0002] Shield machine, the full name is shield tunnel boring machine or full-face tunnel boring machine, it is a kind of tunnel boring machine using shield method. , The machine has the characteristics of completing the tunnel with one excavation, and the excavation, propulsion, and expansion are all completed by the machine. [0003] In order to facilitate the use of the shield machine in the harsh tunnel environment, in the prior art, the rotary cutter head and the limit frame are installed by multiple clamping methods to provide stability for the shield machine. However, the shield machine uses When installing in the way of clamping, since most of the rotary cutterhead and the limit frame of the shield machine are made of metal, there is a certain gap between the me...
