Problems solved by technology

[0004] The purpose of the present invention is to: in the prior art, the repair of the shield segments is carried out by cranes, the number of cranes in the workshop is limited, and it is necessary to perform the work of moving in and out, and the shield segments are erected sideways in the repair area. However, there is a problem that the transfer efficiency is low, and the side of the shield segment cannot be repaired in time, which affects the repair efficiency of the shield segment. A shield segment repair system and method are provided, which can replace the crane in the workshop for treatment. The transportation work of repairing the shield segment improves the transfer efficiency of the shield segment, and the shield segment does not need to be flipped when repairing the side, which simplifies the repair process of the shield segment and speeds up the repair efficiency of the shield segment

Embodiment 1

[0065] Such as Figure 1-Figure 3 As shown, a shield segment repair system of the present invention includes truss one 1, truss two 2 and repair production line 3, both truss one 1 and truss two 2 are equipped with a transport trolley 4, and the transport trolley 4 is used to transport the shield The construction segment 8, the conveying trolley 4 is provided with a fixing device, and the fixing device is used to fix the shield segment 8;

[0066]The repair production line 3 includes a plurality of support frames 31 and a transfer mechanism. The plurality of support frames 31 are arranged at intervals to form a production line. The support frames 31 are used to hold the inner arc surface of the shield segment 8. The transfer mechanism can support The shield segment 8 is transferred between the frames 31, the transport trolley 4 can slide along the truss one 1 to the support frame 31 at the head end of the repair production line 3, and the transport trolley 4 can slide along th...

Embodiment 2

[0081] A kind of shield tunneling segment 8 repairing method of the present invention uses a kind of shield tunneling segment 8 repairing system as described in embodiment 1, comprises the following steps:

[0082] A. Control the delivery trolley 4 of the truss-1 to move to the shield segment stripping area, and use the segment suction cup machine 42 to perform the stripping operation;

[0083] B. The conveying trolley 4 of the control truss-1 transfers the shield segment 8 after demoulding and places it on the support frame 31 at the head end of the repair production line 3, and completes the moving-in work of the shield segment 8 to be repaired;

[0084] C. Control the transfer trolley 33 to transfer the shield segment 8 on the support frame 31 to the adjacent support frame 31, and the workers perform inspection and repair;

[0085] D. After the shield segment 8 is repaired, continue to control the transfer trolley 33 to transfer the repaired shield segment 8 on the support ...

Abstract

The invention relates to the technical field of shield segment machining, and discloses a shield segment repairing system and method. The shield segment repairing system comprises a first truss, a second truss and a repairing production line, the first truss and the second truss are each provided with a conveying trolley, the conveying trolleys are used for conveying shield segments, and the conveying trolleys are provided with fixing devices; the fixing device is used for fixing a shield segment; the repairing production line comprises a plurality of supporting frames and a transferring mechanism, the multiple supporting frames are arranged at intervals to form the production line, the supporting frames are used for supporting the inner arc face of the shield segment, the transferring mechanism can transfer the shield segment among the multiple supporting frames, the conveying trolley can slide to the supporting frame at the head end of the repairing production line along the first truss, and theconveying trolley can slide to the supporting frame at the end of the repairing production line along the second truss. According to the shield segment repairing system and method, the transferring efficiency of the shield segment can be improved, the side face of the shield segment does not need to be turned over for repairing, the repairing procedure of the shield segment is simplified, and the repairing efficiency of the shield segment is improved.

Description

technical field [0001] The invention relates to the technical field of shield tunneling segment processing, in particular to a shield tunneling segment repair system and method. Background technique [0002] The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel. The production of the shield segment is usually made of high-strength impermeable concrete, which is sealed with the finished shield segment mold. After pouring, it is formed, and after pouring, it needs to be transported to the repair area, steam curing area, etc. for maintenance. [0003] At present, the cranes in the workshop are usually used to move the shield segments to be repaired into the repair area, and the repaired shield segments will also be moved out by the cranes. However, there are generally only one or two cranes in the workshop, and the cranes need to be used concurrently. When...
