Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and in particular to a tunnel segment support frame. Background Technology

[0002] Shield tunneling is the main method for constructing subway and underground structural engineering projects. Subway tunnels typically include connecting passages for purposes such as connectivity, drainage, maintenance, and fire rescue. The tunnel segments are the main assembly components in shield tunneling, forming the innermost barrier of the tunnel. They bear the responsibility of resisting soil pressure, groundwater pressure, and other special loads. The tunnel segments are the permanent lining structure of shield tunnels, and their quality directly affects the overall quality and safety of the tunnel, influencing its waterproofing and durability. High-strength, impermeable concrete is typically used in the production of tunnel segments to ensure reliable load-bearing capacity and waterproofing. Production mainly utilizes prefabricated segment molds, which are formed after sealed concrete pouring.

[0003] Based on the above, currently, after the prefabrication of tunnel segments used in shield tunnels is completed, the segments are mostly transported by transport vehicles. However, when transporting the segments, the existing transport vehicles often stack the segments directly together, which makes the segments prone to shaking and collision, leading to corner damage or even missing segments, thus reducing the overall hardness of the segments. Summary of the Invention

[0004] In view of this, the present invention provides a tunnel segment support frame, which has a locking support frame, a bearing frame seat and a support frame, thereby solving the problem that after the prefabrication of tunnel segments used in shield tunnels is completed, the segments are mostly transported by transport vehicles. However, when transporting tunnel segments by existing transport vehicles, the segments are mostly stacked together directly, which makes the segments easy to shake and collide, resulting in corner damage or even missing segments, and reducing the overall hardness of the segments.

[0020] Beneficial effects

[0021] The locking side seat allows the load-bearing support to be installed above the transport vehicle. This, combined with the mounting slot, allows for the assembly of multiple load-bearing frames. Simultaneously, the locking hole and locking bolts position and lock the locking support frame, thus placing the limiting support frame on both sides of the load-bearing frame. This locking and assembling of the load-bearing frame by the limiting support frame allows for assembly and locking. The shifting motor, in conjunction with a bevel gear, drives the threaded push shaft to rotate. This threaded push shaft, in conjunction with a threaded support block, pushes and assembles the entire load-bearing sleeve frame, adjusting the distance between the two sets of support frames. The support frame, in conjunction with the load-bearing column, provides load-bearing support to the bottom sides of the segment. Simultaneously, the drive motor rotates the threaded column, synchronously adjusting the position of multiple threaded sleeves and moving the limiting pressure column. The system presses down on the supporting tunnel segments, and the limiting pressure column, together with the fixed clamp, clamps and limits the supporting tunnel segments, thus enabling the carrying and transportation of the tunnel segments. After the tunnel segments are transported to the appropriate position, the sliding support column, together with the sliding sleeve block, can push and adjust the rotating support, thereby driving the entire load-bearing support to move. After the load-bearing support moves to the appropriate position, the rotating support can rotate and adjust the load-bearing support, and the rotating support block can rotate and adjust the rotating carrier plate. In turn, the load-bearing support plate can support the rotating carrier plate, thus allowing the load-bearing support to rotate 90 degrees and be set on both sides of the support frame. The rotating carrier plate can provide stable load-bearing support for the rotating load-bearing support. After the limiting pressure column and the fixed clamp are reset and unlocked, the tunnel segments carried by the load-bearing support column can be transported and unloaded.

[0049] The specific usage and function of this embodiment: In this invention, during use, the transport vehicle is first driven to a suitable position. Then, the load-bearing support 1 is installed on top of the transport vehicle by locking the side seat 101. The load-bearing support 1, in conjunction with the mounting slot 201, assembles multiple sets of load-bearing brackets 2. At the same time, the locking opening 102, in conjunction with the locking bolt 104, positions and locks the locking support frame 103, thereby setting the limiting support frame 105 on both sides of the load-bearing bracket 2, so that the limiting support frame 105 assembles and locks the load-bearing bracket 2. The shifting motor 305, in conjunction with a bevel gear, drives the threaded push shaft 306 to rotate. This causes the threaded push shaft 306, in conjunction with the threaded support block 402, to assemble and push the entire bearing sleeve frame 4, thereby adjusting the distance between the two sets of support frames 403. The support frames 403, in conjunction with the load-bearing pillars 404, then provide load-bearing support to the bottom sides of the pipe segment. Simultaneously, the drive motor 504 drives the threaded support pillar 503 to rotate, thereby synchronously adjusting the positions of multiple sets of threaded sleeve seats 505, and simultaneously driving the limit pressure column 5... 052 moves to a new position, causing the limiting pressure column 5052 to press against the supported segment. The limiting pressure column 5052, in conjunction with the fixing clamp 5057, clamps and limits the supported segment, thus enabling the segment to be carried and transported. After the segment is transported to a suitable position, the sliding support column 206, in conjunction with the sliding sleeve block 207, can push and adjust the rotating support 208, thereby driving the entire load-bearing support 3 to move. After the load-bearing support 3 moves to a suitable position, the rotating support 208 can support the load-bearing support. 3. The rotating support block 2091 can rotate the rotating carrier plate 2092, and the load-bearing support plate 209 can support the rotating carrier plate 2092. Thus, the load-bearing support 3 is rotated ninety degrees to be set on both sides of the load-bearing frame 2. The rotating carrier plate 2092 can provide stable load support for the rotating load-bearing support 3. After the limit pressure column 5052 and the fixed clamping block 5057 are reset and unlocked, the pipe segment carried by the load-bearing support column 404 can be lifted and transported.
