Description

Technical Field

[0001] This utility model relates to the field of shield tunnel segment technology, and in particular to a modulated large-diameter shield tunnel segment horizontal assembly device. Background Technology

[0002] Tunnel boring machine (TBM) segments are the main assembly components in TBM construction. They form the innermost barrier of the tunnel, resisting soil pressure, groundwater pressure, and other special loads. TBM segments are the permanent lining structure of a shield-type tunnel, and their quality directly affects the overall quality and safety of the tunnel, influencing its waterproofing and durability. TBM segments can be assembled directly inside the tunnel or pre-assembled on level ground for overall use.

[0003] The inventors believe that the following defects often exist: when workers need to assemble shield tunnel segments, the shield tunnel segments are large in size and heavy in weight, making it difficult for workers to carry the shield tunnel segments for a long time and maintain the same posture for a long time during assembly, which may lead to injury to the workers or the shield tunnel segments falling, thus causing problems affecting the health of the workers and damage to the shield tunnel segments; therefore, in order to address the above problems, a modulating large-diameter shield tunnel segment horizontal assembly device is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty for workers to handle and assemble shield tunnel segments for extended periods, leading to worker injuries or shield tunnel segments falling off, thus affecting worker health and shield tunnel segment damage. The invention proposes a modulating large-diameter shield tunnel segment horizontal assembly device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modulated large-diameter shield tunnel segment horizontal assembly device, comprising a platform, a moving device provided on the arc surface of the platform, the moving device comprising four connecting platforms, all four connecting platforms being slidably connected to the arc surface of the platform, four irregular grooves being formed on the surface of the platform, a support platform being fixedly connected to the side of the connecting platform away from the platform, a servo motor being fixedly connected to the surface of the support platform, a moving frame being slidably connected to the surface of the connecting platform, a drive rod being fixedly connected to the output end of the servo motor, and the arc surface of the drive rod being threadedly connected to the moving frame.

[0006] The aforementioned components achieve the following effect: by setting up a moving device, the shield tunnel segments can be moved and assembled quickly. This avoids the situation where workers need to assemble shield tunnel segments, which are large and heavy, making it difficult for them to carry and maintain the same posture for a long time. This could lead to worker injury or shield tunnel segments falling, thus affecting the health of workers and damaging the shield tunnel segments. This improves the practicality of the device.

[0007] Preferably, two support plates are fixedly connected to the surface of the support platform, and a positioning rod is fixedly connected to one side of the support plate. The arc surface of the positioning rod is slidably connected to the movable frame.

[0008] The effect achieved by the above components is that the positioning rod prevents the moving frame from wobbling slightly as it follows the drive rod, thus avoiding the tilting of the moving frame as it follows the rotation of the drive rod, which would cause the shield tunnel segments to shift in position and result in misalignment of the shield tunnel segments during assembly.

[0009] Preferably, an arc-shaped frame is fixedly connected to the surface of the movable frame, and the arc-shaped frame is made of rubber.

[0010] The aforementioned components achieve the following effects: they position the tunnel segments to be placed on the mobile frame, while the rubber material reduces damage to the tunnel segments and avoids the need for workers to repeatedly compare the placement of the tunnel segments on the mobile frame, thus reducing the workload of the workers.

[0011] Preferably, the lower surface of the movable frame is fixedly connected to four fixed plates, which are arranged in pairs. Each pair of fixed plates is rotatably connected to a roller on the side closest to each other. The surface of the connecting platform has two moving grooves, and the rollers are slidably connected to the surface of the moving grooves.

[0012] The effects achieved by the above components are: the rollers facilitate the rapid movement of the mobile frame, while reducing the friction between the mobile frame and the connecting table, thus reducing frictional damage between the mobile frame and the connecting table.

[0013] Preferably, the platform's arc surface is equipped with a disassembly device, which includes several strip plates. Each strip plate is fixedly connected to the arc surface of the platform. Square blocks are fixedly connected to both sides of the connecting platform. A fixing rod is fixedly connected to the surface of each square block. An operating plate is slidably connected to the arc surface of the fixing rod. An insert plate is fixedly connected to one side of the operating plate. Insertion holes are provided on the surface of the strip plates.

[0014] The aforementioned components achieve the following effect: by setting up a disassembly device, the connecting platform and the platform can be disassembled, so that workers can quickly disassemble the connecting platform from the arc surface of the platform, thereby allowing the assembled shield tunnel segments to be smoothly removed from the surface of the platform, improving the practicality of the device.

[0015] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the square block, and the size of the insert plate is adapted to the size of the strip plate insertion hole.

[0016] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls the operating plate.

[0017] Preferably, the arc surface of the fixing rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the operating plate and the square block, respectively.

[0018] The effect achieved by the above components is that the first spring improves the stability of the insert plate when it limits the connection platform.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting up a moving device, the effect of rapid movement and assembly of shield tunnel segments is achieved. This avoids the situation where workers need to assemble shield tunnel segments, which are large and heavy, making it difficult for workers to carry and maintain the same posture for a long time. This can lead to worker injury or shield tunnel segments falling, thus affecting the health of workers and damaging the shield tunnel segments. This improves the practicality of the device.

[0021] 2. In this utility model, by setting up a disassembly device, the effect of disassembling the connecting platform and the platform is achieved, so that the workers can quickly disassemble the connecting platform from the arc surface of the platform, thereby enabling the assembled shield tunnel segments to be smoothly removed from the surface of the platform, thus improving the practicality of the device.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a modulated large-diameter shield tunnel segment horizontal assembly device, including a platform 1. The arc surface of the platform 1 is equipped with a moving device 2. By setting the moving device 2, the shield tunnel segments can be quickly moved and assembled, avoiding the situation where workers need to assemble shield tunnel segments, which are large and heavy, making it difficult for workers to carry and maintain the same posture for a long time, resulting in worker injury or shield tunnel segments falling, thus affecting the health of workers and damaging the shield tunnel segments. This improves the practicality of the device. The arc surface of the platform 1 is equipped with a disassembly device 3. By setting the disassembly device 3, the connecting platform 201 can be disassembled from the platform 1, so that workers can quickly disassemble the connecting platform 201 from the arc surface of the platform 1, thereby allowing the assembled shield tunnel segments to be smoothly removed from the surface of the platform 1, improving the practicality of the device.

[0029] The following section will describe in detail the specific configuration and function of its moving device 2 and disassembly device 3.

[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the mobile device 2 includes four connecting platforms 201, all four connecting platforms 201 being slidably connected to the arc surface of the platform 1. The surface of the platform 1 has four irregularly shaped grooves. A support platform 202 is fixedly connected to the side of the connecting platform 201 away from the platform 1. A servo motor 203 is fixedly connected to the surface of the support platform 202. A moving frame 204 is slidably connected to the surface of the connecting platform 201. A drive rod 205 is fixedly connected to the output end of the servo motor 203. The arc surface of the drive rod 205 is threadedly connected to the moving frame 204. The surface of the support platform 202 is fixedly connected to... Two support plates 206 are provided, with a positioning rod 207 fixedly connected to one side of each support plate 206. The arc surface of the positioning rod 207 is slidably connected to the moving frame 204. When the servo motor 203 is started, its output drives the drive rod 205 to rotate. At this time, the moving frame 204 and the drive rod 205 undergo threaded motion, causing the moving frame 204 to slide on the arc surface of the positioning rod 207. Simultaneously, the moving frame 204 moves along with the tunnel segment until it enters the irregular groove of the platform 1. At this point, the positioning rod 207 prevents the moving frame 204 from following the drive rod 205 and causing further movement. The slight swaying effect prevents the movable frame 204 from tilting as it rotates with the drive rod 205, which could cause the shield tunnel segments to shift and misalign during assembly. An arc-shaped frame 208, made of rubber, is fixedly connected to the surface of the movable frame 204. This serves to position the shield tunnel segments to be placed on the movable frame 204 while minimizing damage to the segments. This design also avoids the need for multiple position checks when placing the shield tunnel segments on the movable frame 204. To address the issue of increased workload for staff, four fixed plates 210 are fixedly connected to the lower surface of the mobile frame 204. The four fixed plates 210 are arranged in pairs, and a roller 211 is rotatably connected to the side of each pair of fixed plates 210 that is close to each other. Two moving grooves 209 are opened on the surface of the connecting table 201, and the roller 211 is slidably connected to the surface of the moving groove 209. At this time, the roller 211 achieves the effect of facilitating the rapid movement of the mobile frame 204, while reducing the friction between the mobile frame 204 and the connecting table 201, thus reducing frictional damage between the mobile frame 204 and the connecting table 201.

[0031] Reference Figure 4 and Figure 5As shown, specifically, the disassembly device 3 includes several strip plates 31, each of which is fixedly connected to the arc surface of the platform 1. Square blocks 32 are fixedly connected to both sides of the connecting platform 201. A fixing rod 33 is fixedly connected to the surface of each square block 32. An operating plate 34 is slidably connected to the arc surface of the fixing rod 33. An insert plate 35 is fixedly connected to one side of the operating plate 34. Insertion holes are provided on the surface of the strip plates 31. A limit plate 36 is fixedly connected to the end of the fixing rod 33 away from the square block 32. The size of the insert plate 35 matches the size of the insertion hole in the strip plate 31. When the operator pulls the operating plate 34, the operating plate 34 slides on the arc surface of the fixing rod 33, at which point the limit plate 36 restricts the operation. The maximum sliding distance of the operating plate 34 on the arc surface of the fixed rod 33 is achieved, which avoids the situation where the operating plate 34 detaches from the arc surface of the fixed rod 33 due to excessive pulling force when the operator pulls it. The arc surface of the fixed rod 33 is fitted with a first spring 37, and the two ends of the first spring 37 are fixedly connected to the operating plate 34 and the square block 32, respectively. When the operator releases the operating plate 34, the rebound force of the first spring 37 causes the operating plate 34 to slide on the arc surface of the fixed rod 33. At the same time, the operating plate 34 drives the insertion plate 35 to move until the insertion plate 35 is inserted into the insertion hole of the strip plate 31. At this time, the first spring 37 improves the stability of the insertion plate 35 when it limits the connection table 201.

[0032] Working principle: When workers need to assemble tunnel segments, the tunnel segment is placed on the moving frame 204. The center position of the tunnel segment is adjusted by the arc frame 208. After adjustment, the servo motor 203 is started. The output end of the servo motor 203 drives the drive rod 205 to rotate. At this time, the moving frame 204 and the drive rod 205 undergo threaded movement, causing the moving frame 204 to slide on the arc surface of the positioning rod 207. At the same time, the moving frame 204 moves with the tunnel segment. The rollers 211 under the moving frame 204 roll in the moving groove 209 until the moving frame 204 enters the irregular groove of the platform 1. At this time, the effect of rapid movement and assembly of the tunnel segment is achieved. This avoids the situation where workers need to assemble the tunnel segments, which are large and heavy, and it is difficult for workers to carry the tunnel segments for a long time and maintain the same posture for a long time. This can lead to worker injury or the tunnel segment falling, which can affect the health of workers and damage the tunnel segment. This improves the practicality of the device.

[0033] When workers need to move the assembled tunnel segments, the connecting platform 201 needs to be disassembled from the platform 1. At this time, the operating plate 34 is pulled, causing it to slide on the arc surface of the fixed rod 33. The first spring 37 is stretched, and the operating plate 34 drives the insert plate 35 to move until the insert plate 35 disengages from the insertion hole of the strip plate 31. Then, the connecting platform 201 is moved, and the connecting platform 201 drives the support frame 202 away from the platform 1. This achieves the effect of disassembling the connecting platform 201 from the platform 1, so that workers can quickly disassemble the connecting platform 201 from the arc surface of the platform 1. This allows the assembled tunnel segments to be smoothly removed from the surface of the platform 1, improving the practicality of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
