Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction engineering, and in particular to a bracket structure for lining segments with multiple specifications. Background Art

[0002] In shield tunnel construction, segment brackets are one of the key equipment. Traditional brackets have a single design and are difficult to adapt to the needs of segments of different specifications, resulting in low construction efficiency and increased costs. Therefore, it has become an urgent need in the industry to develop an adjustable and adaptive bracket structure for lining segments of multiple specifications to meet the needs of different projects.

[0003] However, in actual use, the following deficiencies still exist, such as: the existing lining segment bracket structure, the bracket structure cannot support and adjust lining segments of different specifications. Since it cannot effectively support and adjust lining segments of different specifications, construction workers need to spend more time and energy to manually adjust the position of the segments, which not only increases labor intensity but also reduces construction efficiency. The lack of precise support and adjustment may lead to inaccurate installation positions of the segments, thereby affecting the overall quality and safety of the tunnel. For example, the joints between the segments may not fit tightly, resulting in leakage or seepage problems. If the segments are not installed firmly or there are gaps, there may be safety hazards such as collapse and deformation during the construction process or in later use. This risk is particularly prominent in areas with complex geological conditions or large loads.

[0004] Therefore, the present invention proposes a multi-specification lining segment bracket structure to solve the above problems. Summary of the invention

A tooth groove 47 is provided on the first moving rod 46, and the gear 44 meshes with the tooth groove 47. The first moving rod 46 is fixedly connected to the first support plate 32. When the support rod 43 rotates, the first moving rod 46 can be driven to slide along the hollow tube 45 through the meshing action of the gear 44 and the tooth groove 47, thereby realizing the precise adjustment of the position of the first support plate 32. The hollow tube 45 is fixed to the bottom plate 1 as a sliding track of the first moving rod 46, ensuring the stability and linearity of the first moving rod 46 during the movement, thereby solving the technical problem that the lining segments placed on the first adjustment assembly 3 can be precisely adjusted in height or angle;

[0046] like Figure 1 as well as Figure 6 As shown, a limit assembly 5 is provided on the first adjustment assembly 3, and the limit assembly 5 includes a second support block 51, and the second support block 51 is fixedly connected to the connecting rod 48.

The second limit block 65 is fixedly connected to the base plate 1, and the second slider 66 is slidably connected in the second limit block 65. When the bracket structure reaches the predetermined position, the operator starts the second transmission motor 61, and the output of the second transmission motor 61 drives the rotation of the first rotating rod 62 and the second rotating rod 63, so that the second rotating rod 63 can drive the second moving rod 64 to move, so that the second moving rod 64 can push the second slider 66 to move in the second limit block 65, and the second moving rod 64 is fixedly connected to the second slider 66, and a slide groove 67 is provided on the second limit block 65.

[0048] Working principle:

[0049] like Figure 1-Figure 8As shown, when the bracket structure reaches the predetermined position, the operator first starts the second transmission motor 61, and the output of the second transmission motor 61 drives the rotation of the first rotating rod 62 and the second rotating rod 63, so that the second rotating rod 63 can drive the second moving rod 64 to move, so that the second moving rod 64 can push the second slider 66 to move in the second limit block 65. Due to the movement of the second slider 66, the second slider 66 can drive the first rotating block 68 and the second rotating block 69 to rotate, so that the second limit plate 611 and the second limit rod 612 move downward, so that the second support plate 613 can support the ground. Subsequently, the operator starts the first transmission motor 33, and the output end of the motor drives the screw rod 34 to rotate. As the screw rod 34 rotates, it drives the first slider 35 threadedly connected to it to move along a preset trajectory in the first support plate 32. This movement enables the first slider 35 to drive the first limit plate 36 fixed thereon to move synchronously. When the first limit plate 36 is displaced, the position of the first support block 39 and the first limit block 311 carried by it are adjusted through the interaction between the limit groove 37 set thereon and the first limit rod 310 installed on the first support block 39, so that the relative distance between the two first limit blocks 311 can be adjusted according to actual needs to meet the needs of lining segments of different sizes and specifications, ensuring that they are stably and effectively supported, which not only improves the safety and efficiency during the construction process, but also enhances the flexibility and applicability of the entire bracket structure. When the support rod 43 rotates, the first moving rod 46 can be driven to slide along the hollow tube 45 through the meshing action of the gear 44 and the tooth groove 47, thereby realizing the precise adjustment of the position of the first support plate 32. The hollow tube 45 is fixed on the base plate 1 as a sliding track for the first moving rod 46, ensuring the stability and linearity of the first moving rod 46 during the movement, so that the lining segment can be accurately adjusted in height or angle.
