Embodiment 1

[0042] Embodiment 1, a segment conveying device adapted to the large-slope transportation of the entire ring segment, such as Figure 1-Figure 3 As shown, it includes an underframe 1 connected to the trailer or the main engine of the boring machine, and the underframe 1 is connected to the trailer or the main engine through the first pulling structure 4 or / and the second pulling structure 5, and the first pulling structure 4 is an existing The dragging structure commonly used in the technology, the second dragging structure 5 includes a screw structure, and its length is adjustable. The underframe 1 includes several connected frames, each frame can be rigidly connected or flexibly connected or hinged, and when flexible connection or handover is adopted, it is convenient to follow the trailer or the main engine to realize steering.

[0043] Several stepping units are sequentially arranged on the underframe 1, each stepping unit includes a lifting frame 2 and a sliding frame 3, ...

Embodiment 2

[0058] Embodiment 2, the conveying method of the segment conveying device adapted to the large-slope transportation of the entire ring segment, such as Figure 11 As shown, when excavating in a normal tunnel section or a section with a small slope, the overall hoisting mechanism 6 retracts, the trailer or the main engine pulls the underframe 1 through the first pulling structure 4, and the segment conveying device travels on the assembled segment, the first The drag structure 4 normally adjusts the position of the underframe 1 .

Abstract

The duct piece conveying device comprises a bottom frame, a lifting frame and a sliding frame are arranged on the bottom frame, the bottom frame is connected with an integral lifting unit, the integral lifting unit comprises a plurality of integral lifting mechanisms, and the integral lifting mechanisms are arranged on the bottom frame. One end of the integral hoisting mechanism is connected with the underframe, and the other end of the integral hoisting mechanism is connected with a friction supporting cushion supported on assembled duct pieces in the tunnel; the sliding frame is provided with an anti-slip mechanism which is blocked on the rear side of the duct piece, and the lifting height of the lifting frame is larger than the height of the anti-slip mechanism; an adjusting mechanism is arranged at the position, matched with the segment crane, of the sliding frame and comprises a supporting beam, a segment stopping structure is arranged at the rear end of the supporting beam, the front end of the supporting beam is hinged to the bottom frame or the sliding frame, an adjusting oil cylinder hinged to the bottom frame or the sliding frame is hinged to the rear end of the supporting beam, or the rear end of the supporting beam ascends and descends through the crane. The large-gradient duct piece conveying requirement can be met, and a whole ring of duct pieces can be conveyed.

Description

technical field [0001] The invention relates to the technical field of segment conveying in tunnel construction, in particular to a segment conveying device and a conveying method suitable for large-slope transportation of whole ring segments. Background technique [0002] During segment transportation, the marshalling trolley in the tunnel transports the segment to the grabbing area of ​​the segment crane of the roadheader, and then the segment crane cooperates with the segment conveying device to complete the transfer of the segment to the segment assembly area. However, in the process of existing tunnel construction, more and more tunnel excavation lines need to be excavated with large slopes due to environmental factors, and the slopes range from 0 to 20 degrees. In the construction of large-slope tunnels, due to the large slope, the segments will slide down due to their own weight, making it impossible to use conventional segment conveying devices to complete the transf...
