Description

Technical Field

[0001] This utility model relates to the technical field of tunnel segment assembly, and specifically to a device for tunnel segment assembly. Background Technology

[0002] In shield tunneling, tunnel segments are assembled inside the tunnel using an assembly machine. The assembled segments form a ring shape, formed by splicing multiple segment blocks. Adjacent segment blocks are joined together using segment bolts, and adjacent segment rings are also connected using corresponding bolts. Threaded holes (usually pre-embedded threaded sleeves) are provided in the segment blocks for lifting, allowing the assembly machine to grip the segment. However, during actual assembly, these threaded holes may become loose or damaged, preventing the assembly machine from gripping the segment and thus preventing its assembly from being completed. Discarding the segment directly would be a waste of resources, while re-installing the threaded holes would require re-installing them, causing inconvenience in the segment assembly process. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] See Figure 1 This invention provides a device for assembling tunnel segments, addressing the problem of segment assembly failure due to loosening or damage to pre-embedded lifting holes on the segments. This device enables segment assembly even when lifting holes are unusable, providing a reliable connection to the segments and a foundation for the assembly machine. The device is simple to manufacture, low-cost, and reusable. The following description, in conjunction with the accompanying drawings, illustrates this device for tunnel segment assembly.

[0033] See Figure 1 This image shows a three-dimensional structural diagram of the device for assembling tunnel segments, connected to a tunnel segment block. The following is a combined view... Figure 1 The structure of the device for assembling tunnel segments according to this utility model will be described.

[0034] like Figure 1 As shown, the device for assembling tunnel segments according to this utility model includes a base frame 21, a support frame 22, an mounting component 23, and a threaded connector 24. The base frame 21 is adapted to the inner arc surface 11 of the tunnel segment block 10, and the bottom of the base frame 21 can be attached to the inner arc surface 11. The support frame 22 is fixedly connected to the base frame 21. The mounting component 23 is disposed between the base frame 21 and the support frame 22. The threaded connector 24 is disposed on the mounting component 23.

[0035] When in use, the device of this utility model can be in the following state: Figure 1 As shown, the base frame 21 is placed on the inner arc surface 11 of the segment block 10, and then the base frame 21 is connected to the segment block 10. The threaded connector 24 provides a threaded connection hole, which can be connected to the gripper of the assembly machine to pick up the segment block 10 for assembly. The support frame 22 and the base frame 21 clamp the mounting component 23, which improves the structural stability of the mounting component 23 and ensures that the segment block 10 is firmly and reliably gripped.

[0036] In one specific embodiment of this utility model, such as Figures 1 to 3 As shown, the threaded connector 24 is a threaded sleeve, which is vertically fixed on the mounting part 23.

[0037] The threaded sleeve is preferably an internally threaded sleeve, which can be connected to the gripper of the assembly machine to achieve the gripping of the segment block 10.

[0038] Furthermore, the threaded connector 24 is located at the middle of the mounting member 23.

[0039] The threaded connector 24 is preferably located at the geometric center of the device, so that after the device is connected to the segment block 10, the threaded connector 24 can be located at the middle of the segment block 10.

[0040] Furthermore, the threaded connector 24 is a steel sleeve, which is welded and fixed to the mounting part 23.

[0041] In one specific embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the mounting component 23 is a horizontal bar, which is placed between the base frame 21 and the support frame 22, and is connected and fixed to the base frame 21 and the support frame 22.

[0042] The horizontal bar rests on top of the base frame 21 and is connected and fixed to the base frame 21.

[0043] Furthermore, such as Figures 1 to 4 As shown, the base frame 21 includes a pair of arc-shaped rods 211 that are adapted to the inner arc surface 11 of the tube segment block 10 and a plurality of support rods 212 that are connected between the pair of arc-shaped rods 211; the mounting member 23 is placed on the support rod 212 located in the middle and is connected and fixed to the support rod 212.

[0044] Two of the support rods 212 are connected to the ends of the two arc-shaped rods 211. There are three support rods 212 in the middle, which are spaced apart along the arc-shaped rods 211. The mounting piece 23 is placed on the three support rods 212 in the middle and is fixedly connected to the three support rods 212.

[0045] Preferably, both the curved rod 211 and the support rod 212 are made of steel, such as channel steel. The mounting component 23 is also made of steel, such as channel steel, and can be welded to the corresponding support rod 212.

[0046] The bottom surface of the arc-shaped rod 211 is attached to the inner arc surface 11 of the tube segment block 10.

[0047] Furthermore, the base frame 21 is provided with connecting holes corresponding to the bolt holes on the segment block 10. The segment bolts 14 provided at the bolt holes of the segment block 10 can pass through the connecting holes to connect the base frame 21 and the segment block 10. By using the bolt holes provided on the segment block 10 to connect the base frame 21, after the segment block 10 is installed, the connection between the base frame 21 and the segment block 10 can be easily disconnected, and the device of this utility model can be disassembled from the segment block 10. Moreover, no additional structures (such as mounting holes) are processed on the segment block 10, thus avoiding any impact on the structural stress of the segment block 10.

[0048] Furthermore, the support frame 22 includes four vertical rods 221, a square frame 222 connected to the top of the four vertical rods 221, and at least one strut 223 supported within the square frame 222; the bottom of the four vertical rods 221 is connected and fixed to the base frame 21; the top of the mounting piece 23 is connected and fixed to the corresponding side of the square frame 222 and the strut 223.

[0049] The vertical rod 221 is attached to the side of the corresponding support rod 212 and the arc rod 211, and the vertical rod 221 is welded and fixed to the corresponding support rod 212 and the arc rod 211.

[0050] Furthermore, there are two struts 223, which support and connect the two frame bars that are set in the length direction of the frame 222.

[0051] The direction in which the strut 223 is set is perpendicular to the direction in which the mounting part 23 is set.

[0052] The vertical rods 221, the square frame 222, and the struts 223 of the support frame 22 are all made of steel rods, such as channel steel. The vertical rods 221, the square frame 222, and the struts 223 are fixed together by welding, and the struts 223, the square frame 222, and the mounting parts 23 are also fixed together by welding.

[0053] like Figure 1 As shown, the support frame 22 is located in the middle of the base frame 21.

[0054] The orientation of the base frame 21 is consistent with the length direction of the segment block 10.

[0055] like Figure 1As shown, the side 13 along the length of the segment block 10 is used for docking and connecting with other segment blocks on the segment ring, and the side 12 along the width of the segment block 10 is used for docking and connecting with segment blocks on the same ring. After the corresponding sides of the segment blocks 10 are in contact, they are connected by segment bolts 14.

[0056] The bolt holes on the side 12 of the base frame 21 in the width direction of the segment block 10 are connected by segment bolts 14. After the segment block 10 is transported to the installation position by the assembly machine, the segment block 10 can be connected with the adjacent segment block, and the connection between the two segment blocks can be achieved by adjusting the segment bolts 14. The segment block 10 can also be connected to the segment block on the previous ring. After that, the connection between the base frame 21 and the segment block 10 can be released, and the device of this utility model can be removed from the gripper of the assembly machine.

[0057] The device for assembling pipe segments of this utility model uses full welding at each node to ensure reliable welding quality.

[0058] This utility model discloses a device for assembling pipe segments, which is simple to operate and has high construction efficiency. The device reduces resource waste and effectively speeds up the construction period. It is simple to manufacture and easy to disassemble. The device is reusable and has a high utilization rate.
