Detailed description of the invention
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
Be respectively as marked 1-8 in Fig. 1-5, figure: cutterhead 1, round steel ring 2, ring plate 2.1, welding position 3, round steel cylinder 4, section of jurisdiction 4.1, anterior shield 5, welding position 6, round steel cylinder 7, section of jurisdiction 7.1, middle shield 8.
Embodiment: the present embodiment is specifically related to a kind of shield machine of variable diameter, be intended to overcome the deficiency that existing shield machine can not be general because of the disunity of Tunnel Design standard under identical geological conditions, by the cutterhead of shield machine, anterior shield, middle shield can be applicable to after simple transformation the tunnel of Φ 6200/5500-350 and this two type of Φ 6000/5400-300 simultaneously, to expand the use region of shield machine, reduce shield machine improvement cost.
As Figure 1-5, what the shield machine in the present embodiment related generally to transformation is cutterhead 1, anterior shield 5 and middle shield 8.
As shown in Figure 1, 2, cutterhead 1 is 6250mm according to Φ 6000/5400-300 Subway Tunnel Lining section of jurisdiction its diameter of type selecting, the extrados of cutterhead 1 welds the round steel ring 2 of a 45mm thickness as shell body, to make the diameter of cutterhead 1 increase to 6340mm, meet Φ 6200/5500-350 tunnel lining segment; When later stage is as being used for the construction of Φ 6000/5400-300 tunnel lining segment, only round steel ring 2 thick for the 45mm of welding need be cut off, retrofit work amount is less.It should be noted that, round steel ring 2 is made up of four sections of ring plates 2.1, and each ring plate 2.1 laminating is arranged on the extrados of cutterhead 1, and the extrados of the edge, both sides of each ring plate 2.1 and cutterhead 1 is welded and fixed, i.e. welding position 3.
As shown in Figure 3,4, anterior shield 5 is 6250mm according to Φ 6000/5400-300 Subway Tunnel Lining section of jurisdiction its diameter of type selecting, the extrados of anterior shield 5 welds the round steel cylinder 4 of a 45mm thickness as shell body, to make the diameter of anterior shield 5 increase to 6340mm, meet Φ 6200/5500-350 tunnel lining segment; When later stage is as being used for the construction of Φ 6000/5400-300 tunnel lining segment, only round steel cylinder 4 thick for the 45mm of welding need be cut off, retrofit work amount is less.It should be noted that, round steel cylinder 4 is made up of four sections of sections of jurisdiction 4.1, and the laminating of each section of jurisdiction 4.1 is arranged on the extrados of anterior shield 5, and the extrados of the edge, both sides of each ring plate 2.1 and cutterhead 1 is welded and fixed, i.e. welding position 6.
As shown in Figure 5, middle shield 8 is 6250mm according to Φ 6000/5400-300 Subway Tunnel Lining section of jurisdiction its diameter of type selecting, the extrados of middle shield 8 welds the round steel cylinder 7 of a 45mm thickness as shell body, to make the diameter of middle shield 8 increase to 6340mm, meet Φ 6200/5500-350 tunnel lining segment; When later stage is as being used for the construction of Φ 6000/5400-300 tunnel lining segment, only round steel cylinder 7 thick for the 45mm of welding need be cut off, retrofit work amount is less.It should be noted that, round steel cylinder 7 is made up of four sections of sections of jurisdiction 7.1, and the laminating of each section of jurisdiction 7.1 is arranged on the extrados of middle shield 8, and the extrados of the edge, both sides of each ring plate 2.1 and cutterhead 1 is welded and fixed, and concrete welding position is same as welding position 6.
Above-mentioned shield machine is applicable to Φ 6200/5500-350 tunnel lining segment, during as Φ 6000/5400-300 tunnel lining segment need be used for, then respectively the round steel cylinder 7 on the round steel ring 2 on cutterhead 1, the round steel cylinder 4 on anterior shield 5 and anterior shield 8 is cut off, to realize the variable diameter of shield machine, adapt to dissimilar tunnel; Owing to being made up of some ring plates by the round steel ring cut off, round steel cylinder is made up of some sections of jurisdiction, and adopts the method for part welding, therefore be can be recycled by the round steel ring that cuts off and round steel cylinder.
The beneficial effect of the present embodiment is, shield machine main components only need be cut off cutterhead, anterior shield, middle shield shell body or weld, without the need to again making cutterhead, middle shield, anterior shield, only need new production shield body, and dynamical system in shield machine and other positions inner thereof do not need to carry out transforming the driving requirement that can meet the section of jurisdiction of two types, shield machine retrofit work amount is little, and expense is low, cycle is short, dependable performance after transformation.
