Description

Technical Field

[0001] This utility model relates to the field of segment construction vehicle technology, specifically to a segment construction vehicle for tunnel boring machines. Background Technology

[0002] In tunnel boring machine (TBM) construction, each time the TBM excavates one ring (usually 1.2 or 1.5 meters), a ring of tunnel segments (typically composed of 6-7 segments) is needed to support the newly excavated tunnel wall. The segment car acts like a "freight train" inside the tunnel, responsible for the precise delivery of this "last mile." As a wheel-rail vehicle for transporting tunnel segments, the segment car typically includes two running gears, a frame structure, and running gear covers mounted on the two running gears. The running gear includes wheels, axles, and a braking system.

[0003] Traditional segment construction vehicles have steel outer covers and frame structures. The connection between the outer covers and frame structures is basically done by welding. This poses a risk of corrosion at the weld points between the outer covers and the frame structure, and the connection strength is reduced after the weld points rust. Utility Model Content

[0004] (I) The problem to be solved by this utility model is that there is a risk of corrosion at the welding points of the outer cover of the running section and the beam structure of the traditional segment truck.

[0005] (II) Technical Solution

[0006] A tunnel boring machine segment construction vehicle includes a segment construction vehicle frame, two travel section covers, and two travel section modules. The two ends of the segment construction vehicle frame are respectively connected to the two travel section covers, and the two travel section modules are respectively installed inside the travel section covers.

[0007] The segment vehicle frame includes multiple crossbeams, which are I-shaped structural beams; both ends of the crossbeams penetrate the side walls of the two outer covers of the traveling section; both ends of the crossbeams are connected to the side walls of the two outer covers of the traveling section through inner and outer reinforcements.

[0009] The outer reinforcement includes at least one connecting plate, the connecting plate including a first plate and a second plate that are perpendicular to each other; the second plate of the connecting plate is fixed to the web of the crossbeam by an adhesive layer or threaded fasteners; the first plate of the connecting plate is fixed to the inner surface of the side wall of the outer cover of the walking part by an adhesive layer or threaded fasteners.

[0010] According to one embodiment of the present invention, the inner reinforcement includes two fixing plates, which are respectively located on both sides of the crossbeam in the width direction; the outer reinforcement includes two connecting plates, which are respectively located on both sides of the crossbeam in the width direction.

[0011] According to one embodiment of the present invention, the first long plate of the fixing plate is bonded to the web of the crossbeam, and the second long plate of the fixing plate is bonded to the outer surface of the side wall of the walking part cover.

[0012] According to one embodiment of the present invention, the second plates of the two connecting plates and the web of the crossbeam are connected by a first bolt and a first nut, and the first plates of the two connecting plates are bonded to the inner surface of the side wall of the outer cover of the walking part.

[0032] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] like Figures 1-12 As shown, one embodiment of this utility model provides a tunnel segment construction vehicle, including a segment vehicle frame, two outer covers for the traveling section and two traveling section modules 3. The two ends of the segment vehicle frame are respectively connected to the two outer covers for the traveling section, and the two traveling section modules 3 are respectively installed inside the outer covers for the traveling section.

[0034] The segment car frame includes multiple crossbeams 4, which are I-shaped structural beams; both ends of the crossbeams 4 penetrate the side walls of the two outer covers of the traveling section; both ends of the crossbeams 4 are connected to the side walls of the two outer covers of the traveling section through inner reinforcement 5 and outer reinforcement 6.

[0035] The inner reinforcement 5 includes at least one fixing plate, the fixing plate having a first long plate 111 and a second long plate 112 perpendicular to each other; the first long plate 111 is fixed to the web of the crossbeam 4 by an adhesive layer or threaded fasteners; the second long plate 112 is fixed to the outer surface of the side wall of the outer cover of the traveling part by an adhesive layer or threaded fasteners.

[0036] The outer reinforcement 6 includes at least one connecting plate, which includes a first plate 701 and a second plate 702 that are perpendicular to each other; the second plate 702 of the connecting plate is fixed to the web of the crossbeam 4 by an adhesive layer or threaded fasteners; the first plate 701 of the connecting plate is fixed to the inner surface of the side wall of the outer cover of the traveling part by an adhesive layer or threaded fasteners.

[0037] In this embodiment, both ends of the crossbeam 4 pass through the side walls of the two outer covers of the walking section and enter the interior of the two outer covers. Both ends of the crossbeam 4 are connected to the side walls of the outer covers of the walking section through inner reinforcement 5 and outer reinforcement 6. The fixing plate of the inner reinforcement 5 is connected to the web of the crossbeam 4 and the outer surface of the side wall of the walking section through bonding or threaded fasteners. The connecting plate of the outer reinforcement 6 is connected to the web of the crossbeam 4 and the inner surface of the side wall of the walking section through bonding or bolts. In this way, since the crossbeam 4 and the outer cover of the walking section are no longer connected by welding, but by bonding or threaded fasteners, the problem of reduced connection strength caused by corrosion of the welding points between the crossbeam 4 and the outer cover of the walking section can be eliminated.

[0038] Furthermore, it is worth noting that since the crossbeam 4 and the outer cover of the traveling section are no longer connected by welding but by adhesive or threaded fasteners, the materials of the crossbeam 4 and the outer cover of the traveling section can be the same or different.

[0039] In some embodiments, the crossbeam 4, the inner reinforcement 5, and the outer reinforcement 6 are all composite materials, preferably basalt fiber reinforced epoxy resin composite material (BFRP). This type of composite material has high strength and light weight, thereby reducing the weight of the segment truck and effectively reducing the energy consumption of the segment truck operation.

[0040] It should be noted that basalt fiber reinforced epoxy resin composite material is a high-performance composite material made by combining basalt fiber as a reinforcing material with an epoxy resin matrix. This composite material has high strength and light weight, making it very suitable for fields that require lightweighting (such as aerospace and automotive). It also has advantages such as excellent fatigue resistance and outstanding corrosion resistance.

[0041] Compared to steel plates (Q235), basalt fiber reinforced epoxy resin composite panels generally have higher tensile strength than ordinary steel (such as Q235), while their elastic modulus (stiffness) is usually lower. The weight (density) of basalt fiber composite panels is approximately 2.0 g / cm³. 3 Basalt fiber composite panels are much lighter than steel plates, and they have excellent corrosion resistance and do not rust, while steel plates have poor corrosion resistance and require coating for corrosion protection.

[0042] In this embodiment, the first long plate 111 and the second long plate 112 of the fixing plate are perpendicular to each other. The connecting plate also includes a third plate body 703. The first plate body 701 and the second plate body 702 are perpendicular to each other, and the first plate body 701 and the third plate body 703 are parallel to each other. The width of the third plate body 703 is smaller than both the width of the first plate body 701 and the width of the second plate body 702.

[0043] It should be noted that, as Figure 2 As shown, the outer cover of the walking section includes side plates, and the end of the crossbeam 4 passes through the side plates of the outer cover of the walking section and enters the interior of the outer cover of the walking section.

[0044] Since there are two outer covers for the running gear, for ease of description, they will be arranged from left to right. Figure 1The two outer covers of the walking parts are named walking part cover 1 and walking part cover 2 respectively. The side plate of walking part cover 1 is named first side plate 101, and the side plate of walking part cover 2 is named second side plate 201. Both the first side plate 101 and the second side plate 201 have rectangular holes for the crossbeam 4 to pass through. The left end of the crossbeam 4 passes through the rectangular hole of the first side plate 101 of walking part cover 1 and enters the interior of walking part cover 1. The right end of the crossbeam 4 passes through the rectangular hole of the second side plate 201 of walking part cover 2 and enters the interior of walking part cover 2.

[0045] It should be noted that the crossbeam 4 is usually an I-beam. An I-beam usually includes two flanges and a web. The web is fixed directly to the two flanges and is perpendicular to the flanges.

[0046] In this embodiment, the inner reinforcement 5 includes two fixing plates, which are named the first fixing plate 11 and the second fixing plate 12 for ease of description; the outer reinforcement 6 includes two connecting plates, which are the first connecting plate 7 and the second connecting plate 8.

[0047] The first fixing plate 11 and the second fixing plate 12 are located on both sides of the width direction of the crossbeam 4, and the first fixing plate 11 and the second fixing plate 12 are located outside the outer cover of the walking part. The first long plate 111 of the first fixing plate 11 and the second fixing plate 12 are respectively connected to the two sides of the web plate, and the second long plate 112 of the first fixing plate 11 and the second fixing plate 12 are both connected to the outer surface of the side plate.

[0048] The first connecting plate 7 and the second connecting plate 8 are located inside the outer cover of the walking part. The first connecting plate 7 and the second connecting plate 8 are located on both sides of the width direction of the crossbeam 4, and the second plate body 702 of the first connecting plate 7 and the second connecting plate 8 are respectively connected to the two sides of the web plate. The first plate body 701 of the first connecting plate 7 and the second connecting plate 8 are both connected to the inner surface of the side plate.

[0049] In other words, the ends of the crossbeam 4 are provided with a first fixing plate 11, a second fixing plate 12, a first connecting plate 7, and a second connecting plate 8, so as to strengthen the connection strength between the crossbeam 4 and the side plate and improve the torsional resistance of the crossbeam 4.

[0050] In a first specific embodiment, the fixing plate, connecting plate, and crossbeam 4 are all made of basalt fiber reinforced epoxy resin composite material. Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the first long plate 111 of the first fixing plate 11 is bonded to the front side of the web of the crossbeam 4, the first long plate 111 of the second fixing plate 12 is bonded to the back side of the web of the crossbeam 4, the second long plate 112 of the first fixing plate 11 is bonded to the outer surface of the side plate of the outer cover of the walking part, and the second long plate 112 of the second fixing plate 12 is bonded to the outer surface of the side plate of the outer cover of the walking part.

[0051] A first through hole is provided on the second plate body 702 of the first connecting plate 7, and a second through hole is provided at both ends of the web plate. A third through hole is provided on the second plate body 702 of the second connecting plate 8. After aligning the first through hole of the second plate body 702 of the first connecting plate 7, the second through hole at the end of the web plate, and the third through hole on the second plate body 702 of the second connecting plate 8, a first bolt 9 is used to pass through the first through hole, the second through hole, and the third through hole. Then, a first nut 10 is screwed onto the end of the first bolt 9 and tightened, thereby fixing the first connecting plate 7, the web plate of the crossbeam 4, and the second connecting plate 8 together.

[0052] Furthermore, the first plate body 701 of the first connecting plate 7 is bonded to the inner surface of the side plate, and the first plate body 701 of the second connecting plate 8 is bonded to the inner surface of the side plate.

[0053] As can be seen, in this embodiment, since the crossbeam 4, the first connecting plate 7, the second connecting plate 8, the first fixing plate 11, and the second fixing plate 12 are all composite material plates, the weight of the segment carriage can be effectively reduced while ensuring the structural strength can support the segments, thereby reducing energy consumption. Furthermore, the crossbeam 4 and the side plates of the outer cover of the traveling section are no longer connected by welding, thus avoiding the problem of reduced structural strength due to corrosion at the weld points.

[0054] As another specific embodiment, such as Figure 10 , Figure 11 and Figure 12 As shown, the first long plate 111 of the first fixing plate 11, the web plate of the crossbeam 4, and the first long plate 111 of the second fixing plate 12 are fixed together by a third bolt 15 and a third nut. The second plate body 702 of the first connecting plate 7, the web plate of the crossbeam 4, and the second plate body 702 of the second connecting plate 8 are connected together by a first bolt 9 and a first nut 10. In addition, the first fixing plate 11 and the first connecting plate 7 are located on the same side of the web plate, and the second fixing plate 12 and the second connecting plate 8 are located on the other side of the web plate. The second long plate 112 of the first fixing plate 11, the side plate of the outer cover of the traveling part, and the first plate body 701 of the first connecting plate 7 are connected together by a second bolt 13 and a second nut 14; the second long plate 112 of the second fixing plate 12, the side plate of the outer cover of the traveling part, and the first plate body 701 of the second connecting plate 8 are connected together by a second bolt 13 and a second nut 14.

[0055] That is, holes for the third bolt 15 to pass through are opened on the first long plate 111 of the first fixing plate 11 and the second fixing plate 12, holes for the third bolt 15 to pass through are opened on the web of the crossbeam 4, holes for the second bolt 13 to pass through are opened on the second long plate 112 of the first fixing plate 11 and the second fixing plate 12, holes for the second bolt 13 to pass through are opened on the first plate body 701 of the first connecting plate 7 and the second connecting plate 8, and holes for the second bolt 13 to pass through are opened on the side plate of the outer cover of the walking part.

[0056] Thus, the first fixing plate 11, the second fixing plate 12 and the web plate are fixed together by the third bolt 15 and the third nut; the first fixing plate 11, the side plate of the outer cover of the walking part and the first connecting plate 7 are connected together by the second bolt 13 and the second nut 14; the second fixing plate 12, the side plate of the outer cover of the walking part and the second connecting plate 8 are connected together by the second bolt 13 and the second nut 14; and the first connecting plate 7, the web plate of the crossbeam 4 and the second connecting plate 8 are fixed together by the first bolt 9 and the first nut 10.

[0057] In this embodiment, the fixing plate, connecting plate, and crossbeam 4 are all made of basalt fiber reinforced epoxy resin composite material, or the fixing plate, connecting plate, and crossbeam 4 are all made of steel.

[0058] Compared to the previous embodiment, in this embodiment, the fixing plate and the web plate, the fixing plate and the connecting plate, and the connecting plate and the web plate are all connected by bolts, which facilitates the subsequent replacement or disassembly of components.

[0059] In this embodiment, since the crossbeam 4 and the side plate of the outer cover of the traveling section are no longer connected by welding, but by threaded fasteners, the problem of reduced connection strength caused by corrosion of the weld points between the crossbeam 4 and the outer cover of the traveling section can be eliminated. In addition, the fixed plate and the web plate, the fixed plate and the connecting plate, and the connecting plate and the web plate are all connected by bolts, which facilitates the subsequent replacement or disassembly of components.

[0060] In some embodiments, the top of the plurality of crossbeams 4 is covered with a panel 16, and the panel 16 and the top surface of the crossbeams 4 are bonded together, or the panel 16 and the crossbeams 4 are fixed together by screws or bolts. The panel 16 is a basalt fiber reinforced epoxy resin composite material plate.
