Description

Technical Field

[0001] This application relates to the field of tunnel boring machine (TBM) construction technology, and in particular to a TBM segment assembly and calibration device. Background Technology

[0002] As a highly efficient method for underground tunnel construction, shield tunneling is widely used in engineering fields such as subways, water conservancy, and municipal engineering. As the main supporting structure of the tunnel, the assembly quality of shield segments directly affects the overall stability and safety of the tunnel. In recent years, with the continuous expansion of the scale of tunnel projects, higher requirements have been placed on the accuracy and efficiency of shield segment assembly.

[0003] Existing manual assembly and calibration methods suffer from low accuracy, poor efficiency, and high labor intensity. They rely heavily on the experience and skill level of operators, have large errors, and make it difficult to guarantee safety during installation, thus failing to meet the needs of modern construction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a shield tunnel segment assembly and calibration device, which overcomes the deficiencies of existing technologies. It aims to solve the problems of low accuracy, poor efficiency, and high labor intensity in existing manual assembly and calibration methods. These methods rely heavily on the experience and skill level of operators, have large errors, and make it difficult to guarantee safety during installation, thus failing to meet the needs of modern construction.

[0005] To achieve the above objectives, this application provides the following technical solution: a shield tunnel segment assembly and calibration device, comprising a support mechanism, the support mechanism including a column, a crossbeam slidably connected to one side of the column, a segment assembly mechanism slidably connected to the bottom of the crossbeam, a fixing rod fixedly connected to the front of the segment assembly mechanism, a mounting frame provided at the bottom of the fixing rod, the tops of four sets of mounting frames being fixedly connected to the bottom of the fixing rod, two sets of mounting components being provided between the four sets of mounting frames, the middle parts of the two sets of mounting components being rotatably connected to the mounting frame, and a drive motor being provided at the top of the fixing rod. The output end of the drive motor is fixedly connected to the drive rod through the fixed rod. The drive rod is externally threaded to a horizontal plate. Both ends of the horizontal plate are provided with two sets of rotating grooves and four sets of sliding grooves. The four sets of sliding grooves are located on both sides of the horizontal plate and are interconnected with each other. The mounting assembly includes a rotating component. One end of the rotating component is provided with two sets of sliding blocks. One end of the rotating component is located inside the rotating groove. Both sets of sliding blocks are slidably connected inside the sliding groove. A laser rangefinder is provided at one end of both mounting assemblies. An angle sensor is provided on one side of the fixed rod.

[0006] By adopting the above technical solution and setting a fixed rod, the fixed rod will move synchronously with the segment assembly mechanism during use. When the segment assembly mechanism assembles the shield tunnel segments, the segments need to be lifted. At this time, the drive motor can be driven to move the horizontal plate up and down, thereby rotating the installation components. The laser rangefinder will detect both ends of the segment. During the installation of the segment, the laser rangefinders on both sides will detect both ends of the segment in real time. If there is any deviation during installation, it can be detected in time. After the segment is installed in place, the drive motor can be driven again to make the two sets of laser rangefinders detect both sides of the segment. At the same time, they cooperate with the angle sensor. Then, the real-time installation status of the installed segment and the surrounding segments can be analyzed based on the detected data. When installing segments of different sizes, the laser rangefinder can adjust the measuring angle according to the size of the segment to adapt to it. The device is convenient to use, simple to operate, will not affect the normal installation, and has strong stability.

[0007] As a preferred technical solution of this application, a control panel is provided on one side of the column. The control panel is electrically connected to the drive motor, the angle sensor, and the laser rangefinder. The control panel includes a display screen and a PLC controller.

[0008] By adopting the above technical solution and setting up a control panel, the collected data can be better collected and detected during use, and the operation of the device can be adjusted in real time, further improving the convenience of using the device.

[0009] As a preferred technical solution of this application, each of the four sets of mounting brackets has multiple sets of mounting slots inside, and a connecting shaft is provided in the middle of the rotating part. Both ends of the connecting shaft pass through two sets of mounting slots and are provided with fixing nuts.

[0010] By adopting the above technical solution and setting up mounting slots, the position of the mounting components can be changed through multiple sets of mounting slots during use, making it more flexible in use and further improving the practicality of the device.

[0011] As a preferred embodiment of this application, the mounting component has a slot at one end near the laser rangefinder, and an abutment post is provided on the outside of the slot. The slot and the laser rangefinder are engaged with each other, and one end of the abutment post passes through the slot and abuts with the laser rangefinder.

[0012] By adopting the above technical solution and setting a slot, the laser rangefinder can be further fixed by rotating the abutment post during use to prevent it from falling off. At the same time, the snap-fit ​​design makes it more convenient to replace it in the future.

[0013] As a preferred technical solution of this application, the front of the fixing rod is provided with two sets of mounting blocks, and the interior of each set of mounting blocks is rotatably connected to a lighting lamp assembly.

[0014] By adopting the above technical solution and setting up the installation block, continuous lighting can be provided during use, which can further improve the safety of construction in the dim environment of the tunnel.

[0015] As a preferred technical solution of this application, a stabilizing pad is provided between the abutting post and the laser rangefinder, and the stabilizing pad is made of rubber.

[0016] By adopting the above technical solution and setting a stabilizing pad, the contact between the contact post and the laser rangefinder can be made more stable, reducing the possibility of movement.

[0017] As a preferred technical solution of this application, indicator lights are provided on both sides of the fixing rod, and the indicator lights are electrically connected to the control panel.

[0018] By adopting the above technical solution and setting indicator lights, early warnings can be provided at the installation site during use, further improving safety during use.

[0019] The beneficial effects of this application are:

[0020] 1. By setting a fixed rod, the fixed rod will move synchronously with the segment assembly mechanism during use. When the segment assembly mechanism assembles the shield tunnel segments, the segments need to be lifted. At this time, the drive motor can be driven to move the horizontal plate up and down, thereby rotating the installation components. The laser rangefinder will detect both ends of the segment. During the installation of the segment, the laser rangefinders on both sides will detect both ends of the segment in real time. If there is any deviation during installation, it can be detected in time. After the segment is installed in place, the drive motor can be driven again to make the two sets of laser rangefinders detect both sides of the segment. At the same time, they work together with the angle sensor. Then, the real-time installation status of the installed segment and the surrounding segments can be analyzed based on the detected data. When installing segments of different sizes, the laser rangefinder can adjust the measuring angle according to the size of the segment to adapt to it. The device is convenient to use, simple to operate, will not affect the normal installation, and has strong stability.

[0032] Working Principle: By setting a fixed rod 2, during use, the fixed rod 2 will move synchronously with the segment assembly mechanism 103. When the segment assembly mechanism 103 assembles the shield tunnel segments, the segments need to be lifted. At this time, the drive motor 201 can be driven to move the horizontal plate 203 up and down, thereby causing the installation component 4 to rotate. The laser rangefinder 5 will detect both ends of the segment. During the installation of the segment, the laser rangefinders 5 on both sides will detect both ends of the segment in real time, and can detect any possible deviation during installation. After the segment is installed in place, the drive motor 201 can be driven again. Two sets of laser rangefinders 5 probe both sides of the tube segment, working in conjunction with angle sensors 8. The detected data is then used to analyze the real-time installation status of the installed tube segment and its surrounding segments. When installing tube segments of different sizes, the laser rangefinders 5 can adjust the measuring angle according to the size of the tube segment to adapt to it. The device is easy to use and simple to operate, and will not affect normal installation. It has strong stability. By setting up the control panel 6, the collected data can be better collected and detected during use, and the operation of the device can be adjusted in real time, further improving the convenience of using the device.

[0033] Among them, by setting the mounting slot 301, the position of the mounting component 4 can be changed by setting multiple sets of mounting slots 301 during use, which can make the use more flexible and further improve the practicality of the device. By setting the slot 403, the laser rangefinder 5 can be further fixed by rotating the abutment post 404 during use to prevent it from falling off. At the same time, the snap-fit ​​design can make subsequent replacement more convenient.

[0034] Meanwhile, by setting up the installation block 901, continuous lighting can be provided during use, which can further improve the safety of construction in the dim environment of the tunnel.

[0035] In addition, by setting the stabilizing pad 405, the contact between the abutment post 404 and the laser rangefinder 5 can be made more stable, reducing the possibility of movement; by setting the indicator light 206, the installation site can be warned during use, further improving the safety during use.
