Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine segment commissioning, specifically a platform for assembling and commissioning subway tunnel boring machine segments. Background Technology

[0002] Tunnel boring machine (TBM) segments are the main assembly components in TBM construction, forming the innermost barrier of the tunnel and bearing the responsibility of resisting soil pressure, groundwater pressure, and other special loads. TBM 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. TBM segment production typically uses high-strength, impermeable concrete to ensure reliable load-bearing capacity and waterproofing. Production mainly utilizes prefabricated segment molds, which are formed after sealed concrete pouring.

[0003] The construction process of a subway tunnel boring machine (TBM) first requires opening a vertical shaft at one end of a section of the tunnel, then moving the TBM into the tunnel. The TBM then begins to work according to the pre-set route, excavating from the starting point to another vertical shaft at the end point of the excavation, thus completing the work.

[0004] The existing debugging equipment first places the shield segments on the platform and aligns them one by one. However, the placement of the last shield segment is more troublesome, requiring personnel to correct its position before it can be pushed in. This method is cumbersome and has low work efficiency. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a platform for assembling and debugging subway tunnel segments, so as to solve the technical problem that existing debugging devices require personnel to correct the position before pushing them in, which is cumbersome and has low work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a platform for assembling and debugging subway tunnel segments, comprising a base, a vertical clamping plate fixed to the outer wall of the positioning column, an electromagnetic slide rail installed on one side of the positioning column, a base installed on the top of the electromagnetic slide rail, an inner ring plate fixed to one side of the base, an outer ring plate fixed to the top of the base, a first telescopic rod installed inside the outer ring plate, a fixing plate installed at the output end of the first telescopic rod, and a correction component installed on the top of the electromagnetic slide rail.

[0007] By adopting the above technical solution, the problem of existing shield tunneling segments being directly transported to the subway tunneling site for installation after factory production can be solved. During the installation process, errors may occur between shield tunneling segments, resulting in improper installation. Therefore, assembly and debugging are required before being transported to the subway tunneling site. The existing debugging device first places the shield tunneling segments on the platform and aligns them one by one. However, the placement of the last shield tunneling segment is more troublesome, requiring personnel to correct its position before pushing it in. This method is cumbersome and has low work efficiency.

[0008] The present invention is further configured such that the correction component includes a positioning device installed on the top of the electromagnetic slide rail, and a telescopic rod is installed inside the positioning device, and a positioning block is installed at the output end of the telescopic rod.

[0009] By adopting the above technical solution, after the five shield tunnel segments are placed in the vertical clamping plate, since they are hoisted in, the positions of the five shield tunnel segments may not be properly placed and need to be adjusted again. At this time, with the help of the positioning device, the positions of the five shield tunnel segments are adjusted by telescopic rods and positioning blocks so that they can be neatly aligned and placed inside the vertical clamping plate, which facilitates subsequent testing to see if the sixth shield tunnel segment can match them.

[0010] The present invention is further configured such that a placement groove is provided on the top of the positioning column, and a positioning block groove is provided inside the positioning device.

[0011] By adopting the above technical solution, after the positions of the five shield segments are adjusted, the positioning device can be moved into the placement slot to facilitate the entry of the sixth shield segment.

[0012] The present invention is further configured such that a movable roller is movably mounted at the bottom of the positioning column.

[0013] By adopting the above technical solution, the five shield segments placed inside can be easily moved to the appropriate position under the action of the positioning device and tightly fitted together, which facilitates the inspection of the assembly of the sixth shield segment.

[0014] The present invention is further configured such that positioning magnetic plates are movably installed on both sides of the outer ring plate.

[0015] By adopting the above technical solution, when the sixth shield segment is placed inside the base, the positioning magnetic plate can ensure that the sixth shield segment does not deviate from the proper position during placement, which facilitates subsequent pushing and debugging.

[0016] The present invention is further provided that positioning magnetic blocks are fixed at both ends of the outer ring plate.

[0017] By adopting the above technical solution, the positioning magnetic plate used for positioning can be disassembled as needed, making the operation simple and convenient.

[0018] In summary, the present invention has the following main advantages:

[0019] This utility model solves the problem that existing shield tunneling segments, after being manufactured in the factory and directly transported to the subway tunneling site for installation, may have errors between the shield tunneling segments during the installation process, resulting in problems with proper installation. Therefore, it is necessary to assemble and debug before transporting them to the subway tunneling site. The existing debugging device first places the shield tunneling segments on the platform and aligns them one by one. However, the placement of the last shield tunneling segment is more troublesome, requiring personnel to correct its position before pushing it in. This method is cumbersome and has low work efficiency.

[0020] This invention, by setting up telescopic rods and positioning blocks, allows for the adjustment of the positions of five shield tunnel segments after they have been placed in the vertical clamping plate, since they are hoisted in. This adjustment is made by using the positioning device, telescopic rods, and positioning blocks to align the five shield tunnel segments neatly inside the vertical clamping plate, facilitating subsequent testing to ensure that the sixth shield tunnel segment can be matched with them.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A platform for assembling and debugging tunnel segments in subway tunnels, such as Figure 1 - Figure 3 As shown, the device includes a base 1 and a positioning column 3. A vertical clamping plate 9 is fixed to the outer wall of the positioning column 3, and an electromagnetic slide rail 7 is installed on one side of the positioning column 3. The base 1 is installed on the top of the electromagnetic slide rail 7, and an inner ring plate 2 is fixed to one side of the base 1. An outer ring plate 6 is fixed to the top of the base 1, and a first telescopic rod 5 is installed inside the outer ring plate 6. A fixing plate 4 is installed at the output end of the first telescopic rod 5. A correction component is also installed on the top of the electromagnetic slide rail 7. This addresses the problem that existing shield tunnel segments, after being manufactured in the factory, are directly transported to the subway shield tunneling site for installation. During the installation process, errors may occur between the shield tunnel segments, resulting in poor installation. Therefore, assembly and debugging are required before transporting them to the subway shield tunneling site. Existing debugging devices first place the shield segments on a platform and align them one by one. However, placing the last shield segment is more troublesome, requiring personnel to correct its position before pushing it in. This method is cumbersome and has low work efficiency.

[0028] Please see Figure 1 - Figure 3 The correction assembly includes a positioning device 12 installed on top of the electromagnetic slide rail 7, and a telescopic rod 14 is installed inside the positioning device 12. A positioning block 15 is installed at the output end of the telescopic rod 14. When the five shield tunnel segments are placed in the vertical clamping plate, since they are hoisted in, the positions of the five shield tunnel segments may not be properly placed and need to be adjusted again. At this time, with the help of the positioning device, the telescopic rod and the positioning block are used to adjust the positions of the five shield tunnel segments so that they can be neatly aligned and placed inside the vertical clamping plate, which facilitates subsequent testing to see if the sixth shield tunnel segment can match them.

[0029] Please see Figure 1 - Figure 3 The top of the positioning column 3 is provided with a placement groove 18, and the inside of the positioning device 12 is provided with a positioning block groove 13, so that after the positions of the five shield segments are adjusted, the positioning device 12 can be moved into the placement groove 18 to facilitate the entry of the sixth shield segment.

[0030] Please see Figure 1 - Figure 3 The bottom of the positioning column 3 is movably equipped with a movable roller, which allows the five shield segments placed inside to be easily moved to the appropriate position under the action of the positioning device 12 and tightly fitted together, making it convenient to inspect the assembly of the sixth shield segment.

[0031] Please see Figure 1 - Figure 2Positioning magnetic plates 10 are movably installed on both sides of the outer ring plate 6. When the sixth shield segment is placed inside the base 1, the positioning magnetic plates 10 can ensure that the sixth shield segment does not deviate from the proper position during placement, which facilitates subsequent pushing and debugging.

[0032] Please see Figure 1 - Figure 2 The outer ring plate 6 has positioning magnetic blocks 11 fixed at both ends, which allows the positioning magnetic plate 10 used for positioning to be disassembled as needed, making the operation simple and convenient.

[0033] The working principle of this utility model is as follows: When it is necessary to assemble and debug the cast shield tunnel segments, firstly, five shield tunnel segments are hoisted into the vertical clamping plate 9 set on the outer wall of the base 1 by a crane. Then, the controller 16 controls the positioning quick slots 13 fixed at the ends of the two telescopic rods 14. At this time, the telescopic rods 14 generate elastic force, which pushes the five shield tunnel segments placed inside the vertical clamping plate 9 to position the five shield tunnel segments.

[0034] After the five shield tunnel segments are positioned, the four positioning pulleys 17 fixed to the bottom of the positioning device 12 are pushed along the electromagnetic slide rail 7 to move the positioning device 12 into the placement slot 18 opened inside the positioning column 3. Then, the device for placing the sixth shield tunnel segment is moved to the corresponding position. At this time, the sixth shield tunnel segment is hoisted between the inner ring plate 2 fixed to the end of the base 1 and the fixing plate 4 fixed to one side of the first telescopic rod 5. At this time, the sixth shield tunnel segment presses against the first telescopic rod 5, and the first telescopic rod 5 generates elastic force, thereby moving the sixth shield tunnel segment forward. The rear limit is set, and during the hoisting process, the sixth shield tunnel segment is positioned left and right by the positioning magnetic suction plates 10 installed on both sides of the inner ring plate 2 and the outer ring plate 6. At this time, the six shield tunnel segments are pushed along the electromagnetic slide rail 7 to push the four fixed pulleys 8 fixed at the bottom of the base to the corresponding position. If the sixth shield tunnel segment can be pushed into the corresponding position and match the first five shield tunnel segments, it can be assembled. If the sixth shield tunnel segment cannot be pushed into the corresponding position and match the first five shield tunnel segments, resulting in misalignment or gaps, it cannot be assembled and needs to be adjusted.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
