Problems solved by technology

[0003]The hob installed on the cutter head of the shield machine is generally fixed. When reaming and trimming the tunnel, manual adjustment or replacement of the hob is required. Once the traditional hob is worn out, it needs to be replaced manually, and the steps of changing the tool are cumbersome

Abstract

The invention discloses a hob capable of being pushed out, which includes an oil cylinder arranged on a TBM (tunnel boring machine) cutter, a sliding part movably connected with the cutter and driven by the oil cylinder to move, and a hob connected on the sliding part. Due to the adoption of the technical scheme, the hob capable of being pushed out can adjust the hob position through adjusting the oil cylinder feed rate when being used for tunnel chambering and trimming, and further a cutter I is pushed out to meet the requirements of chambering and trimming. The hob capable of being pushed out also can serve as a standby hob; after other hobs are worn, the standby hob is pushed out of the cutter and the number of hob change times is reduced.

Description

technical field [0001] The invention relates to a cutter, in particular to a push-out hob. Background technique [0002] Shield tunnel boring machine, referred to as shield machine, is a special construction machine for tunnel excavation. Using shield machine for tunnel construction has the advantages of high automation, manpower saving, fast construction speed, one-time hole formation, no climate influence, and open When excavating, it can control ground subsidence, reduce the impact on ground buildings, and not affect water surface traffic when excavating underwater. In the case of long tunnel lines and large buried depths, it is more convenient to use shield machines for construction. Economically sound. [0003] The hob installed on the cutter head of the shield machine is generally fixed. When the tunnel is reaming and trimming, manual adjustment or replacement of the hob is required. In addition, once the fixed hob is worn out, it needs to be replaced manually, and th...
