Self-propelled crawler feeder for shield machine

Abstract

The invention discloses a self-propelled crawler feeder for a shield machine, which comprises a vehicle frame, a left load-bearing wheel, a right load-bearing wheel, a left track, a right track, a left drive unit, a right drive unit and a segment support structure. There are several right load-bearing wheels respectively, and they are arranged symmetrically on the left and right sides of the vehicle frame; The load-bearing wheels respectively form left and right driving wheels, and the left and right driving units can respectively drive the left and right driving wheels to rotate; the segment support structure is used to support the segment and its bottom is fixed on the upper side of the vehicle frame. The shield machine uses a self-propelled crawler feeder to carry its own power unit, which can walk on the lined segments by itself; it improves the service life without damaging the segments; it has strong terrain adaptability and large load; it avoids the traditional segment assembly Repeat cumbersome actions; improve construction efficiency and simplify the structure.

Description

technical field [0001] The invention relates to a slice feeder for a shield machine, in particular to a self-propelled crawler slice feeder for a shield machine. Background technique [0002] In shield construction, the function of the feeder is to transfer the segments unloaded by the segment crane to the grasping range of the segment assembly machine. The basic structure of a traditional tablet feeder includes a fixed bracket, a sliding bracket, and a jacking bracket. When the shield machine is digging forward, the feeder is connected to the shield body through an iron chain, and the shield body drags the feeder forward. When assembling the segment, the segment crane lifts the segment from the segment transport vehicle and places it at the end of the feeder, and then the sliding cylinder of the feeder pushes the sliding bracket to push the segment forward to the designated position and lifts The oil cylinder lifts up the jacking bracket, lifts the segment, the sliding oi...

AI Technical Summary

Problems solved by technology

[0003] From the above workflow, it can be seen that the traditional film feeder is dragged forward by the shield body, the friction between the bottom of the film feeder and the segment will cause wear and tear, the life of the film feeder is short, and the segment may be damaged

In addition, the working process of the tablet feeder to supply the segment is cumbersome and complicated, and the autonomy of the tablet feeder is poor, resulting in low construction efficiency
