[0001] This utility model relates to the field of bracket technology, and in particular to a simple bracket device for high-efficiency measuring instruments in TBM tunnels. Background Technology

[0002] In tunnel engineering constructed using TBMs (Tunnel Boring Machines), surveying plays a crucial role in ensuring construction accuracy and project quality. Stable support for surveying instruments is fundamental to ensuring the accuracy and reliability of measurement data. Existing supports mostly employ fixed tripods or straight rod supports. This makes it difficult for fixed-angle tripods to remain level on irregular tunnel walls or uneven ground, while straight rod supports cannot withstand the high-frequency vibrations generated by the tunnel boring machine and cannot adapt to the complex and changing working conditions within TBM tunnels. Therefore, this invention proposes a simple, high-efficiency surveying instrument support device for TBM tunnels. Utility Model Content

[0027] Example

[0028] like Figure 1and Figure 2 As shown in Figure 2 , the simple bracket device of the TBM roadway high-efficiency measuring instrument proposed by the present utility model includes: a support plate 1. A shaft rod 9 is fixedly arranged on the bottom surface of the support plate 1. Chute grooves 10 are respectively opened on both sides of the support plate 1, and the chute grooves 10 are symmetrically arranged. One end of the support plate 1 is fixedly provided with a mounting plate 2 connected to the roadway through bolts, and the support plate 1 can be stably installed on the inner wall of the roadway through the mounting plate 2.

[0029] Furthermore, a tray 3 is fixedly arranged on the upper surface of the support plate 1. A centering screw 4 is fixedly arranged on the upper surface of the tray 3. Through the centering screw 4, it can ensure that the measuring instrument is accurately installed on the tray 3, thereby improving the accuracy of the detection of the detection instrument.

[0030] Secondly, a support plate 5 is movably sleeved on the outer wall of the shaft rod 9. One end of the support plate 5 is rotatably connected to a mounting seat 6, and the mounting seat 6 is arranged in a "convex" shape structure. The mounting seat 6 can contact the inner wall of the roadway with different concavities and convexities, thereby improving the stability of the installation.

[0031] As Figure 2 and Figure 3 shown in Figure 2 and Figure 3 , a first strengthening component 7 for improving support is arranged between the support plate 1 and the support plate 5. The first strengthening component 7 includes an adjusting bolt 71 threaded through the support plate 1. One end of the adjusting bolt 71 is fixedly provided with a rotating cap for facilitating manual rotation of the adjusting bolt 71. The other end of the adjusting bolt 71 is rotatably connected to a linkage block 72 through a bearing. Both ends of the linkage block 72 are respectively fixedly provided with sliding blocks 73, so that the linkage block 72 can drive the sliding blocks 73 to move. The sliding blocks 73 are slidably connected to the support plate 1 through the chute grooves 10 to ensure the stability of the movement of the linkage block 72. A connecting rod 74 is rotatably connected to the sliding block 73. One end of the connecting rod 74 is rotatably connected to a connecting block 75. The connecting block 75 is fixedly connected to the support plate 5, and it can make the connecting block 75 drive the support plate 5 to rotate, thereby adjusting its installation angle.

[0032] As Figure 2 and Figure 4 shown in Figure 2 and Figure 4 , a second strengthening component 8 for improving support is arranged between the support plate 1 and the support plate 5. The second strengthening component 8 includes a threaded rod 81 movably penetrating through the upper surface of the support plate 1, which can make the threaded rod 81 move stably according to the limit of the support plate 1. A limit nut 82 is threadedly sleeved on the outer wall of the threaded rod 81. There are two limit nuts 82, and they are respectively located on the upper surface and the bottom surface of the support plate 1, which can stably limit the threaded rod 81. The lower end of the threaded rod 81 is rotatably connected to a connecting seat 83. Both ends of the connecting seat 83 are respectively fixedly connected with limit rods 84. One end of the limit rod 84 is rotatably connected to a fixed seat 85. One end of the fixed seat 85 is fixedly connected to the support plate 5, so as to provide support for the support plate 5 and improve the support strength, thereby resisting the high-frequency vibration generated by the operation of the roadheader.

[0033] In this embodiment, when installing the simple support device for the measuring instrument in the TBM tunnel, the mounting plate 2 is first fixed to the tunnel wall with bolts to provide a basic mounting point for the entire support. Subsequently, if the tunnel wall is irregular, the angle of the support plate 5 needs to be adjusted to ensure that the measuring instrument is placed horizontally.

[0034] At this point, loosen the limiting nut 82 on the threaded rod 81 and rotate the adjusting bolt 71. Since the thread of the adjusting bolt 71 passes through the support plate 1, it will move along the support plate 1 during rotation, causing the adjusting bolt 71 to drive the connecting block 72 to move synchronously. The sliders 73 at both ends of the connecting block 72 slide in the groove 10 of the support plate 1, ensuring that the connecting block 72 moves smoothly. At the same time, the sliders 73 are connected to the connecting block 75 through the connecting rod 74, thereby pushing or pulling the support plate 5 to rotate around the shaft 9 until the support plate 5 reaches a suitable angle, realizing flexible adjustment of the angle of the support plate 5 according to the actual situation of the roadway.

[0035] While the adjustment plate 5 moves, it also drives the fixed seat 85 to move. The fixed seat 85 drives the connecting seat 83 to move through the limit rod 84. The connecting seat 83 drives the threaded rod 81 to move on the support plate 1.

[0036] After adjustment, the mounting plate 6 is installed on the tunnel wall using bolts through the through holes. To resist the high-frequency vibrations generated by the tunneling machine, the loosened limit nut 82 is rotated in the opposite direction, so that the limit nut 82 is tightly attached to the upper and lower surfaces of the support plate 1, thereby limiting the threaded rod 81 and ensuring the stability of the support plate 5.

[0037] Finally, the testing instrument is securely mounted on the tray 3 using the centering screw 4. The mounting plate 2 is firmly fixed to the tunnel wall, providing a reliable reference point for the entire bracket assembly.

[0038] After the bracket device is installed and adjusted, the measuring instrument is stably mounted on the tray 3 using the centering screw 4. At this point, the position and height of the measuring instrument are relatively fixed, and the baseline on which it is based can be used as a reference for the roadway waistline. During roadway construction, the waistline is used to precisely control the slope and height of the roadway. The stable installation of the bracket device ensures the consistency and accuracy of the waistline baseline, providing a reliable reference for subsequent construction.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
