Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a rotating transport vehicle for the split-type starting segments of a shield tunnel. Background Technology

[0002] With the acceleration of urbanization in my country, urban construction is shifting from above-ground to underground, and subway construction has entered a period of rapid development. Shield tunneling will develop towards a wider scope and higher technical level, facing greater construction risks and difficulties. Due to the limitations of dense urban buildings and other conditions, the available ground construction sites are often quite small. Generally, shield tunneling is designed for separate launching, with a short launching shaft and a small footprint. Under the condition of separate shield launching, the limitations of the launching shaft prevent the supporting trolley and bridge from being lowered into the shaft, thus rendering the double-rail beam and segment feeder unusable. Segments are usually placed on rails and pushed by battery-powered vehicles. This method easily causes damage to the outer curved surface and corners of the segments, posing significant safety hazards and making it difficult to guarantee segment quality. Furthermore, the labor intensity for workers is high, and transporting each segment is time-consuming and inefficient. Therefore, the existing segment transportation methods suffer from low efficiency, poor safety, and high labor intensity for workers, urgently requiring a new type of segment transport vehicle to solve these problems.

The bearing plate is used to support the tunnel segments. The moving device is connected to the bottom of the main body of the transport vehicle to make the shield tunnel segment rotating transport vehicle move.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] A rotating transport vehicle for the split-type starting segments of a tunnel boring machine includes: a transport vehicle body, a moving device 6, a driving device, a bearing plate 2, and a rotating device 1;

[0030] When the segment assembly machine grabs the segment, it is required that the segment be transported perpendicular to the tunnel axis to the bottom of the assembly machine before it can be grabbed. That is, the segment needs to be rotated when it is transported to the designated position. Therefore, a rotating device is installed on the main body of the transport vehicle. The output end of the rotating device is connected to the bearing plate 2 to make the bearing plate 2 rotate relative to the main body of the transport vehicle. The bearing plate 2 is used to support the segment. The moving device 6 is connected to the bottom of the main body of the transport vehicle to make the shield tunneling segment rotating transport vehicle move.

[0031] The drive unit is used to provide power to the rotating transport vehicle for the starting segments of the tunnel boring machine.

[0032] The main body of the transport vehicle includes a base plate 3 and a rear plate that is perpendicularly connected to one side of the base plate. The rotating device is mounted on the base plate 3.

[0033] The support plate 2 is provided with segment limiting members 5, which are symmetrically arranged on both sides of the upper surface of the support plate 2. In this embodiment, the segment limiting members 5 are made of No. 10 channel steel. When the segment is placed on the support plate 2, since the two segment limiting members 5 are upward strip-shaped protrusions on the support plate 2, there is a certain recessed area between the two segment limiting members 5 relative to the protrusion. When the segment is placed on the support plate 2, the two segment limiting members 5 limit the bottom edge of the segment, and the arc-shaped area at the bottom of the segment is placed in the recessed area, thereby realizing the stable placement of the segment on the support plate 2.

[0034] The rotating device 1 is a rotating bearing, but it can also be other forms of rotating devices or components. Rotating bearings are low in cost and small in size, making them very suitable for this application scenario.

[0035] In this embodiment, the shield tunnel segment rotating transport vehicle also includes rotation limiting components. Specifically, the rotation limiting components include a first limiting block disposed at the bottom of the bearing plate 2 and a second limiting block disposed above the base plate 3. Two of each of the first and second limiting blocks are provided, with the two first limiting blocks facing each other and the two second limiting blocks also facing each other. The limiting blocks allow the bearing plate 2 to rotate 90° clockwise and 90° counterclockwise relative to the base plate 3. After rotation, the segments can be transported to the area below the assembly machine, where the assembly machine grips the assembly head using its lifting head.

[0036] The shield tunneling segment rotating transport vehicle also includes a connecting component 4, which is connected to the rear plate and used to connect the drive device. The drive device is a small trolley with a power source. The small trolley can hold the tail grease and HBW grease canisters. Due to the low temperature in some areas, the tail grease and HBW grease may clog the pipelines. The small trolley moves with the shield body to avoid the grease pipelines from being extended and to ensure that the grease pipelines are unobstructed.

[0037] The moving device 6 is a track chute, which moves the entire device by cooperating with the track. Other moving methods can also be used depending on the actual situation.

[0038] In this embodiment, both the base plate 3 and the bearing plate 2 are steel plates, and the length and width of the bearing plate 2 are smaller than those of the base plate 3. The specifications of the base plate 3 are: 2500mm in length, 1600mm in width, and 20mm in thickness. The specifications of the bearing plate 2 are: 1400mm in length, 1300mm in width, and 20mm in thickness.

[0039] The working end of the segment limiting component 5 is provided with a rubber anti-slip pad, and the rubber anti-slip pad is provided with anti-slip texture. By providing the anti-slip rubber pad and anti-slip texture, the friction between the segment and the segment can be increased, making the entire transportation process more stable.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
