Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine (TBM) construction technology, and in particular to a separate starting segment transportation structure for a TBM. Background Technology

[0002] In current construction of transportation tunnels and water resource allocation projects, most projects use tunnel boring machines (TBMs) for excavation, with a single vertical shaft for launching. When the TBM is launched in sections, some of the trolleys need to be lowered into the shaft along with the main machine, resulting in insufficient space and suitable positions inside the shaft for hoisting the tunnel segments, making the segment hoisting and lowering construction very difficult. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a segment transportation structure for a tunnel boring machine (TBM). This structure utilizes a trolley to provide space for the segment hoisting and lowering into the shaft, thereby realizing the hoisting and transportation of the segments.

[0004] To achieve the above objectives, the present invention provides a separate starting segment transportation structure for a tunnel boring machine, comprising a trolley, a segment transportation trolley, and a hoisting and rotating device. The top of the trolley is provided with a longitudinal segment hoisting inlet, the bottom of the trolley is provided with a segment rotation hoisting outlet, and a segment transportation space is provided below the trolley. The segment transportation trolley is movably disposed below the trolley and can move to the segment rotation hoisting outlet. The hoisting and rotating device is disposed on the trolley and is used to rotate the segment from longitudinal to transverse at the segment rotation hoisting outlet and hoist it onto the segment transportation trolley.

[0005] As a further improvement of this utility model, the hoisting and rotating device includes a traveling beam, a traveling trolley, an electric hoist, a segment hoisting spreader beam, and a segment hoisting head. The traveling beam is set on the top of the trolley and does not obstruct the longitudinal hoisting entrance of the segment. The traveling trolley is movably mounted on the traveling beam. The electric hoist is vertically mounted on the traveling trolley. The segment hoisting spreader beam is mounted on the electric hoist. The segment hoisting head is mounted on the segment hoisting spreader beam. An assembly head is installed on the segment, and the segment is rotatably mounted on the segment hoisting head through the assembly head.

[0006] As a further improvement of this utility model, the segment transport trolley is provided with a support frame for horizontally placing the segments and trolley wheels for moving. A transport trolley track is laid under the trolley, and the segment transport trolley is movably mounted on the transport trolley track by means of the trolley wheels.

[0007] As a further improvement of this utility model, the trolley is provided with a pair of front trolley wheels and a pair of back trolley wheels, and a trolley track is provided below the trolley. The trolley is movably mounted on the trolley track by means of the front trolley wheels and the back trolley wheels.

[0008] As a further improvement of this utility model, the spacing between the wheels of the front trolley allows the segment transport trolley to pass laterally loaded with segments.

[0009] As a further improvement of this utility model, the distance between the front carriage wheels is greater than the distance between the back carriage wheels, and the front carriage wheels and the back carriage wheels are respectively set on different carriage tracks.

[0010] As a further improvement of this utility model, the trolley is provided with a space for longitudinally placing the tubular segments.

[0011] The beneficial effects of this utility model are as follows: By modifying the trolley, this utility model enables the trolley to have space for lifting and lowering tunnel segments into the well. During construction, the tunnel segments are first lifted onto the trolley by an external gantry crane. Since the lateral space on the trolley is narrow, a longitudinal lifting inlet for the tunnel segments is set on the trolley so that the tunnel segments are lifted longitudinally into the trolley through the longitudinal lifting inlet. Then, the lifting and rotating device on the trolley lifts the tunnel segments out along the tunnel segment rotating lifting outlet to the bottom of the trolley. At this time, there is sufficient lateral space. The lifting and rotating device rotates the tunnel segments from longitudinal to lateral and finally loads them onto the tunnel segment transport trolley. The tunnel segment transport trolley transports the tunnel segments to the tunnel segment assembly machine for tunnel segment assembly, thereby realizing the lifting and transportation of tunnel segments.

[0015] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0016] like Figure 1 , 2 As shown, a segment transportation structure for a tunnel boring machine includes a trolley 1, a segment transportation trolley 2, a hoisting and rotating device 3, and a gantry crane 4.

[0017] Gantry crane 4 is installed on the ground at the starting shaft opening and is used to lift and transport tunnel segments 5 into the shaft. Gantry crane 4 is a commonly used piece of equipment for lifting tunnel segments 5, so it will not be described in detail here.

[0018] The trolley 1 is located inside the launching shaft and is a modified conventional trolley 1. The top of the trolley 1 is equipped with a longitudinal segment hoisting inlet 11, and the bottom is equipped with a segment rotation hoisting outlet 12. The longitudinal segment hoisting inlet 11 facilitates the longitudinal hoisting of the segment 5 onto the trolley 1, and the rotation hoisting outlet 12 facilitates the hoisting of the segment 5 to the area below the trolley 1. Space is reserved below the trolley 1 for the hoisting, rotation, and transportation of the segment 5. The trolley 1 also has space for the longitudinal placement of the segment 5 for temporary storage.

[0019] The segment transport trolley 2 is movably positioned below the trolley 1 and can move to the segment rotation lifting outlet 12. The segment transport trolley 2 is equipped with a support frame 21 for horizontally placing the segments 5 and trolley wheels 22 for movement. A transport trolley track is laid below the trolley 1, extending from below the trolley 1 to the segment assembly machine. The segment transport trolley 2 is movably positioned on the transport trolley track via the trolley wheels 22. The segment transport trolley 2 can transport the segments 5 from below the trolley 1 to the segment assembly machine.

[0020] A hoisting and rotating device 3 is mounted on the trolley 1 and is used to rotate the tunnel segment 5 from longitudinal to transverse at the tunnel segment rotation hoisting outlet 12 and hoist it onto the tunnel segment transport trolley 2. Specifically, the hoisting and rotating device 3 includes a traveling beam 31, a traveling trolley 32, an electric hoist 33, a tunnel segment hoisting spreader beam 34, and a tunnel segment hoisting head 35. The traveling beam 31 is located on the top of the trolley 1 along its length and does not obstruct the longitudinal hoisting inlet 11 of the tunnel segment. The traveling trolley 32 is movably mounted on the traveling beam 31. The electric hoist 33 is vertically mounted on the traveling trolley 32. The tunnel segment hoisting spreader beam 34 is mounted on the electric hoist 33. The tunnel segment hoisting head 35 is mounted on the tunnel segment hoisting spreader beam 34. An assembly head 51 is installed on the tunnel segment 5, and the tunnel segment 5 is rotatably mounted on the tunnel segment hoisting head 35 through the assembly head 51. With the above structure, the tunnel segment 5 can be hoisted to move forward and backward, move up and down, and rotate left and right.

[0021] The trolley 1 has a walking function. The trolley 1 is equipped with a pair of front trolley wheels 13 and a pair of rear trolley wheels 14. A trolley track is provided below the trolley 1, and the trolley 1 is movably mounted on the trolley track via the front trolley wheels 13 and the rear trolley wheels 14. When the segment transport trolley 2 transports the segment 5, it needs to pass between the front trolley wheels 13. Therefore, in this embodiment, the spacing between the front trolley wheels 13 is widened to allow the segment transport trolley 2 to pass laterally loaded with the segment 5, while the rear trolley wheels 14 maintain their original spacing. Since the spacing between the front trolley wheels 13 is greater than the spacing between the rear trolley wheels 14, the front trolley wheels 13 and the rear trolley wheels 14 are respectively mounted on different trolley tracks. This structure ensures the normal transport of the segment 5 while satisfying the walking function of the trolley 1.

[0022] The process for hoisting and transporting segment 5 using the above structure is as follows:

[0023] 1. The segment 5 is hoisted from the ground to the shaft by the gantry crane 4 and then hoisted into the trolley 1 through the longitudinal hoisting inlet 11. Since the lateral space on the trolley 1 is narrow, the segment 5 needs to be hoisted into the trolley 1 longitudinally.

[0024] 2. The traveling trolley 32 of the hoisting and rotating device 3 drives the electric hoist 33 and the segment hoisting spreader beam 34 to travel to directly above the segment 5. The electric hoist 33 is started to descend so that the segment hoisting spreader beam 34 is lowered close to the segment. The assembly head 51 is installed on the hoisting hole of the segment 5 and connected to the hoisting head of the segment hoisting spreader beam 34. The electric hoist 33 is started to rise to lift the segment 5 and transport it to the segment rotating hoisting outlet 12 through the traveling trolley 32. Then the electric hoist 33 is lowered so that the segment 5 is lifted out through the segment rotating hoisting outlet 12 to the bottom of the trolley 1. The segment 5 is manually rotated 90 degrees from longitudinal to transverse. Finally, the segment 5 is placed on the segment transport trolley 2.

[0025] 3. The segment transport trolley 2 transports the segment 5 to the segment assembly machine via the trolley track. The segment assembly machine then grabs the segment 5 and completes the assembly.

[0026] The above-described embodiments are merely illustrative of this utility model. Any equivalent embodiments made by those skilled in the art without departing from the technical features disclosed in this utility model, and without departing from the technical features of this utility model, shall still fall within the scope of the technical features of this utility model.
