Abstract

The embodiment of the present invention relates to the technical field of excavation equipment, and specifically discloses a telescopic mechanism for a cutter head of a shield machine, including a cutter head and a support seat; a driven toothed disc and a driving toothed disc meshing with each other are arranged in the support seat for rotation, The supporting seat is provided with an adjustment assembly coaxially fixedly connected with the driving toothed disc; a swinging frame is supported and slidably arranged in the supporting seat, and a guide column is fixedly installed on one side of the surface of the driven toothed plate, so that The swing frame is slidably sleeved on the guide post through the strip-shaped through hole opened on it; a support link is fixedly installed on one side of the swing frame, and the end of the support link extending outside the support seat is connected to the guide column. The cutterheads are supported and connected by connecting pieces. In the embodiment of the present invention, by adjusting the position of the swing frame in the support seat, the relative position between the cutter head and the support seat can be adjusted under the linkage action of the support link.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of excavation equipment, in particular to a shield machine cutter head telescopic mechanism. Background technique [0002] The shield machine is a special construction machine for tunneling. Using the shield machine for tunnel construction has a high degree of automation, saves manpower, fast construction speed, one-time hole formation, is not affected by the climate, and can control ground subsidence during excavation. The impact on ground buildings and the characteristics of not affecting water surface traffic during underwater excavation. In the case of long tunnel lines and large buried depths, it is more economical and reasonable to use shield machines for construction; At the same time, the replaceable cutter is inserted into the rock formation or soil, and for the convenience of tool change, the cutter needs to be pulled out from the rock formation or soil. With the needs of...
