Abstract

The invention discloses a supporting device for TBM end well excavating equipment for subway construction. The supporting device comprises a mounting plate, wherein a first motor is connected to the top of the mounting plate; a rotating shaft is connected to the output end of the first motor; the end, away from the first motor, of the rotating shaft penetrates through the mounting plate and is connected with a first screw rod; a large gear is connected to the outer wall of the first screw rod; a rotating rod is rotationally connected to the bottom of the mounting plate through a bearing; a small gear engaged with the large gear is connected to the outer wall of the rotating rod; a fixing plate is connected to the end, away from the mounting plate, of the rotating rod; and a fixing pipe is connected to the outer wall of the fixing plate. According to the supporting device, the end well excavating equipment can carry out excavating operation under the condition that the terrain is not leveled, the construction efficiency of the end well excavating equipment is improved, the supporting balance degree and stability of the end well excavating equipment are effectively guaranteed, and therefore the end well excavating equipment is prevented from being damaged, the stability is high, the efficiency is high, and the use requirements of people in production and life are met.

Description

technical field [0001] The invention relates to the technical field of equipment for subway construction, in particular to a support device for TBM end shaft excavation equipment for subway construction. Background technique [0002] TBM, tunnel boring machine (Tunnel tunnel, Boring tunneling). It is divided into open tunnel boring machine and shield tunnel boring machine.
