Shield tunneling machine tunnel internal segment unloading device and working method thereof

Abstract

The invention discloses a shield tunneling machine tunnel internal segment unloading device. The shield tunneling machine tunnel internal segment unloading device comprises a loading plate, a mountingframe, a right unloading platform, a left unloading platform and a top unloading platform, the mounting frame is arranged on the side wall of the loading plate, and the right unloading platform and the right unloading platform are correspondingly arranged on the two sides of the mounting frame. The shield tunneling machine tunnel internal segment unloading device has the beneficial effects that alower clamping groove below pressing grip plates is connected with segments in a buckled mode, a plurality of arc-shaped press racks which are arranged in a matched mode at equal intervals press theouter walls of the segments, it is guaranteed that the segments are gripped more firmly by the pressing grip plates, the segments are unloaded more efficiently by a grip unloading seat, the broken segments are squeezed and shivered more efficiently and delicately, and the shivered fragments are prevented from causing damage to parts on the device; and in addition, in the extension adjustment process of four pressing grip plates driven by a first hydraulic pump, two matching extension shafts are matched with a first hydraulic shaft in a sleeve plate to extend and connect, it is guaranteed thata total loading plate and the pressing grip plates are moved and adjusted more smoothly and reliably, it is guaranteed that the segments are connected more accurately by the pressing grip plates in asleeve mode, and the friction loss of each part of the grip unloading seat during working is reduced.

Description

technical field [0001] The invention relates to a segment dismantling device, in particular to a segment unloading device inside a shield machine tunnel and a working method thereof, belonging to the technical field of segment dismantling devices. Background technique [0002] The pipe unloading device is used more and more frequently on the shield machine. The main function of the pipe unloading device is to clamp and pull the pipes arranged in the underground tunnel to remove them, so as to improve the efficiency and smoothness of the shield machine traveling inside the tunnel. . [0003] The existing segment unloading device inside the shield machine tunnel still has many deficiencies in use. The existing segment unloading device inside the shield machine tunnel has a slow unloading efficiency for the segment, and the device can cover when it is working. The area range is small, the diversity of the device's work is poor, and the fastness of the unloading device to the c...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the segment unloading device inside the tunnel of the shield tunneling machine has a slow efficiency in unloading the segment; and the area covered by the device is small; the diversity of the device work is poor; The tightness of the clamping is poor; during the unloading of the segment by the device, the fragmented segment is too large to cause scratches and damage to the components on the device; the friction loss of the components on the unloading device is large during work, and the working Poor stability and firmness lead to poor stability and low precision of the unloading device; the unloading device is not comprehensive enough to unload segments inside the tunnel; the unloading device can only unload segments of the same diameter and width, and the adaptation of the work In view of the problem of small scope, a segment unloading device and its working method inside the shield machine tunnel are proposed
