Problems solved by technology

Segment assembly equipment is generally located in the front area of ​​the shield machine and can only move within the limited forward and backward movement stroke inside the shield machine
At the same time, the segment transport vehicle (usually a rail battery flatbed car) is limited by the space inside the shield machine, and cannot directly transport the segments to the working area of ​​the segment assembly equipment. Unload each segment from the segment transport vehicle and hoist it to the segment assembly area
Compared with the subway tunnel shield machine with a diameter of 6 meters, the excavation tunnel diameter of the small-diameter shield machine is generally less than 4 meters, and the working space in the shield machine is more limited, and traditional mobile motors cannot be used Drive trolley and electric chain hoist to carry out segment reversing
Due to the small working space in the radial direction, the rewinding speed of the segment from the segment unloading area to the segment assembly area is slow and the work efficiency is low

Abstract

The invention discloses a duct piece reshipment device for a shield tunnel, comprising a walking trolley (3) arranged on a walking pathway (2), a drive mechanism used for driving the walking trolley (3) to move along the walking pathway (2), and a grabbing mechanism (4) capable of moving up and down, wherein the walking pathway (2) is arranged in a shield tunnel with a small diameter; the lower end of the grabbing mechanism (4) capable of moving up and down is connected with a duct piece (7) to be reshipped, and the upper end of the grabbing mechanism (4) is connected with the walking trolley (3). Due to rapid reshipment speed and high working efficiency, the duct piece reshipment device is particularly applicable to the shield tunnel with a small diameter.

Description

technical field [0001] The invention relates to a reversing mechanical device, in particular to a segment reversing device for a shield tunnel. Background technique [0002] The rapid development of domestic urban subway construction has prompted the rapid development of methods and technologies for subway tunnel construction. Among them, the shield tunnel construction method has the advantages of construction safety, high efficiency, environmental protection and high degree of automation compared with the traditional mining tunnel construction method because it can complete tunnel excavation, muck transportation and tunnel support at one time. At present, the construction method of shield tunneling has become the preferred construction method in the construction of subway tunnels in most cities. [0003] The material used for tunnel support after excavation by the shield machine is generally a prefabricated annular reinforced concrete segment with a certain width and thick...
