Description

Technical Field

[0001] This application relates to the field of tunnel boring machines, and more specifically, to a quantitative detection device for tunnel boring machine cutter wear. Background Technology

[0002] The cutterhead of a tunnel boring machine (TBM) is the core component for tunnel excavation. It directly undertakes the task of breaking rocks and cutting soil. Its performance and lifespan directly affect the efficiency and cost of TBM construction. It includes two types of cutters: roller cutters and cutting cutters. The cutters need to be inspected regularly for wear to prevent damage during operation due to excessive wear.

[0003] Existing technologies for wear detection of tunnel boring machine (TBM) cutters mainly include visual inspection, such as taking images of the outer surface of the cutter with a camera and then using image recognition technology to analyze the amount of wear.

[0004] However, the existing quantitative detection equipment for shield cutter wear still has the following shortcomings in use: When detecting shield cutters, since the top, bottom and sides of the shield cutter need to be photographed, the camera is mostly moved manually to photograph multiple sides of the cutter. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a quantitative detection device for shield tunneling cutter wear, which aims to improve the problem that when using a camera to take pictures, it is mostly necessary to manually move the camera to capture multiple sides of the cutter.

[0006] This application provides a quantitative detection device for shield tunneling cutter wear, including a workbench, a shield tunneling machine cutter disposed above the workbench, a camera for acquiring image information disposed above the workbench, an image processing device for processing image information connected to the top of the workbench, a rotation mechanism for driving the shield tunneling machine cutter to rotate and lift disposed above the workbench, and a clamping mechanism for fixing the shield tunneling machine cutter disposed above the workbench. The rotating mechanism includes a track component, the outer surface of which is provided with two sets of first tracks and two sets of second tracks, and the two ends of the two sets of first tracks and second tracks are connected.

[0007] In one specific implementation, an L-shaped component is connected to the top of the workbench, and a slider is connected to one end of the L-shaped component, the slider being able to slide inside the first track and the second track.

[0008] In the above implementation process, by setting up the slider, the slider can slide inside the first and second tracks when the track component rotates. Since one end of the slider is connected to an L-shaped component and fixed above the worktable, the slider cannot move. Through the action of the slider, the track component can move up and down while rotating.

[0009] In one specific implementation, the first track is a vertically downward slide rail, and the second track is a slide rail that slowly rises along the outer surface of the track component.

[0010] In the above implementation process, by setting the first track and the second track, and by making the first track a vertical downward track, the slider can move downward along the first track in the vertical direction as soon as it reaches the top of the first track. When the slider is stationary, it is equivalent to the track component rising. When the slider slides to the bottom of the first track, it contacts the second track. On the second track, the slider slowly rises along the direction of the second track. When the slider is stationary, it is equivalent to driving the track component to slowly descend.

[0011] In one specific implementation, a motor is connected to the top of the workbench, the output shaft of the motor is connected to a circular plate, a telescopic damping rod is connected to the top of the circular plate, the other end of the telescopic damping rod is connected to the bottom of the track component, and a spring is sleeved on the outer surface of the telescopic damping rod.

[0012] In the above implementation process, by setting up the motor, the circular plate can be rotated by controlling the motor, which in turn drives the track component to rotate. When the track component moves downward, the spring is compressed and the telescopic damping rod is contracted. When the slider slides to the top of the first track, the spring and the telescopic damping rod release elastic potential energy, driving the track component to move upward, so that the slider slides to the bottom of the first track.

[0013] In one specific implementation, the top of the track component is connected to an inner bearing ring, the top of the inner bearing ring is connected to a placement component, and the outer surface of the outer bearing ring is connected to a second guide plate.

[0014] In the above implementation process, by setting up the bearing, when the track component rotates, it can drive the inner ring of the bearing to rotate, thereby driving the placement component used to place the tunnel boring machine cutter to rotate.

[0015] In one specific implementation, a second housing is connected to the top of the workbench, a second guide rod is connected inside the second housing, and a second guide plate is slidably connected to the outer surface of the second guide rod.

[0016] In the above implementation process, by setting the second guide rod, the second guide plate can slide on the outer surface of the second guide rod, and the second guide plate can move up and down inside the second housing to prevent the outer ring of the bearing from rotating, and the outer ring of the bearing can move up and down.

[0017] In one specific implementation, a connector is connected to the outer surface of the bearing outer ring, and a third rack plate is connected to the other end of the connector. A first gear is rotatably arranged above the worktable, and a first housing is connected to the top of the worktable. A first guide rod is connected inside the first housing, and a first guide plate is slidably connected to the outer surface of the first guide rod. A second rack plate is connected to one side of the first guide plate, and both the third rack plate and the second rack plate are meshed with the outer surface of the first gear.

[0018] In the above implementation process, by setting the connecting parts, the third rack plate can be driven to move when the outer ring of the bearing moves up and down, thereby driving the meshing first gear to rotate, which in turn drives the second rack plate to move in the opposite direction to the third rack plate. The second rack plate drives the first guide plate to slide on the outer surface of the first guide rod.

[0019] In one specific implementation, a rotating shaft is rotatably connected through the interior of the first guide plate. One end of the rotating shaft is connected to a second gear, and the other end of the rotating shaft is connected to the mounting end of the camera. A first rack plate is connected to the top of the worktable. A spacer rack is provided on one side of the first rack plate, and the second gear can mesh with one side of the first rack plate.

[0020] In the above implementation process, by setting the first rack plate, when the first guide plate moves up and down, the second gear can be rotated through the first rack plate, and the camera can be rotated through the bearing. When the shield machine cutter moves to the top, the camera can take pictures of the bottom of the shield machine cutter. When the shield machine cutter moves to the bottom, the camera can take pictures of the top of the shield machine cutter. When the shield machine cutter is in the middle section, the camera can take pictures of the four sides of the shield machine cutter.

[0021] In one specific embodiment, the clamping mechanism includes a third housing connected to one side of the placement member, and a bidirectional screw is rotatably connected inside the third housing, one end of which passes through the third housing and is connected to an adjustment knob.

[0022] In the above implementation process, by adjusting the knob settings, the bidirectional screw can be driven to rotate inside the third housing by operating the adjustment knob.

[0023] In one specific implementation, the outer surface of the bidirectional screw is threaded with two sets of threaded seats, one side of which is connected to a clamping plate, and one end of the clamping plate penetrates the outer surface of the placement component.

[0024] In the above implementation process, by setting the threaded seat, when the bidirectional screw rotates, it can drive the two sets of first threaded seats to move, thereby adjusting the distance between the two sets of first threaded seats. Furthermore, the movement of the first threaded seats drives the clamping plates to move, and the two sets of clamping plates fix one end of the shield machine cutter inserted into the placement component.

[0025] Compared with the prior art, the beneficial effects of this application are as follows: By setting up the rotating mechanism, the shield machine cutter can be rotated by controlling the motor, and at the same time, the shield machine cutter can be moved up and down. When the shield machine cutter moves to the top, the camera can capture the bottom of the shield machine cutter. When the shield machine cutter moves to the bottom, the camera can capture the top of the shield machine cutter. When the shield machine cutter is in the middle section, the camera can capture the four sides of the shield machine cutter. This solves the problem that when using a camera to capture images, it is mostly necessary to manually move the camera to capture images of multiple sides of the cutter. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Please see Figure 1 This application provides a quantitative detection device for shield tunneling cutter wear, including a worktable 1.

[0031] Please see Figure 1 The shield machine cutter 6 is installed above the workbench 1. A camera 5 for acquiring image information is installed above the workbench 1. An image processing device 4 for processing image information is connected to the top of the workbench 1. A rotating mechanism 2 for driving the shield machine cutter 6 to rotate and lift is installed above the workbench 1. A clamping mechanism 3 for fixing the shield machine cutter 6 is installed above the workbench 1.

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10The rotating mechanism 2 includes a track component 2013. The outer surface of the track component 2013 is provided with two sets of first tracks 2016 and two sets of second tracks 2018. The two ends of the two sets of first tracks 2016 and second tracks 2018 are connected.

[0033] In the specific configuration, an L-shaped component 2010 is connected to the top of the workbench 1. One end of the L-shaped component 2010 is connected to a slider 2017. The slider 2017 can slide inside the first track 2016 and the second track 2018. The slider 2017 allows the track component 2013 to rotate while the slider 2017 slides inside the first track 2016 and the second track 2018. Since one end of the slider 2017 is connected to the L-shaped component 2010 and fixed above the workbench 1, the slider 2017 cannot move. Through the action of the slider 2017, the track component 2013 can move up and down while rotating.

[0034] In the specific configuration, the first track 2016 is a vertically downward sliding rail, and the second track 2018 is a sliding rail that slowly rises along the outer surface of the track component 2013. With the first track 2016 being a vertically downward track, the slider 2017 can move downwards along the vertical direction of the first track 2016 as soon as it reaches above it. When the slider 2017 is stationary, it is equivalent to the track component 2013 rising. When the slider 2017 slides to the bottom of the first track 2016, it contacts the second track 2018. On the second track 2018, the slider 2017 slowly rises along its direction. When the slider 2017 is stationary, it is equivalent to the track component 2013 slowly descending.

[0035] In the specific setup, a motor 208 is connected to the top of the workbench 1. The output shaft of the motor 208 is connected to a circular plate 209. A telescopic damping rod 2012 is connected to the top of the circular plate 209. The other end of the telescopic damping rod 2012 is connected to the bottom of the track component 2013. A spring 2011 is sleeved on the outer surface of the telescopic damping rod 2012. By controlling the motor 208, the circular plate 209 can be rotated, which in turn drives the track component 2013 to rotate. When the track component 2013 moves downward, the spring 2011 is compressed, and the telescopic damping rod 2012 contracts. When the slider 2017 slides to the top of the first track 2016, the spring 2011, in conjunction with the telescopic damping rod 2012, releases its elastic potential energy, causing the track component 2013 to move upward, so that the slider 2017 slides to the bottom of the first track 2016.

[0036] In a specific configuration, the top of the track component 2013 is connected to the inner ring of the bearing 2014, the top of the inner ring of the bearing 2014 is connected to the placement component 2015, and the outer surface of the outer ring of the bearing 2014 is connected to the second guide plate 206. The bearing 2014 is configured such that when the track component 2013 rotates, it drives the inner ring of the bearing 2014 to rotate, thereby driving the placement component 2015, which is used to place the shield machine cutter 6, to rotate.

[0037] In a specific configuration, a second housing 202 is connected to the top of the workbench 1, and a second guide rod 204 is connected inside the second housing 202. A second guide plate 206 is slidably connected to the outer surface of the second guide rod 204. The second guide rod 204 allows the second guide plate 206 to slide on the outer surface of the second guide rod 204. The second guide plate 206 moves up and down inside the second housing 202 to prevent the outer ring of the bearing 2014 from rotating, and the outer ring of the bearing 2014 can move up and down.

[0038] In the specific configuration, a connector 207 is connected to the outer surface of the outer ring of the bearing 2014, and a third rack plate 2022 is connected to the other end of the connector 207. A first gear 2021 is rotatably mounted above the worktable 1. A first housing 201 is connected to the top of the worktable 1. A first guide rod 203 is connected inside the first housing 201. A first guide plate 205 is slidably connected to the outer surface of the first guide rod 203. A second rack plate 2020 is connected to one side of the first guide plate 205. The third rack plate 2022 and the second rack plate 2020 are both meshed with the outer surface of the first gear 2021. Through the connection 207, when the outer ring of the bearing 2014 moves up and down, it drives the third rack plate 2022 to move, which in turn drives the meshed first gear 2021 to rotate. This causes the second rack plate 2020 to move in the opposite direction to the third rack plate 2022. The second rack plate 2020 then drives the first guide plate 205 to slide on the outer surface of the first guide rod 203.

[0039] In the specific setup, a rotating shaft 2024 is rotatably connected through the interior of the first guide plate 205. One end of the rotating shaft 2024 is connected to a second gear 2023, and the other end of the rotating shaft 2024 is connected to the mounting end of the camera 5. A first rack plate 2019 is connected to the top of the worktable 1. A spacer rack is provided on one side of the first rack plate 2019. The second gear 2023 can mesh with one side of the first rack plate 2019. Through the setting of the first rack plate 2019, when the first guide plate 205 moves up and down, the second gear 2023 can rotate through the first rack plate 2019. The bearing 2014 drives the camera 5 to rotate, so that when the shield machine cutter 6 moves to the top, the camera 5 can capture the bottom of the shield machine cutter 6. When the shield machine cutter 6 moves to the bottom, the camera 5 can capture the top of the shield machine cutter 6. When the shield machine cutter 6 is in the middle section, the camera 5 can capture the four sides of the shield machine cutter 6.

[0040] In a specific configuration, the clamping mechanism 3 includes a third housing 301, which is connected to one side of the placement member 2015. A bidirectional screw 304 is rotatably connected inside the third housing 301. One end of the bidirectional screw 304 passes through the third housing 301 and is connected to an adjustment knob 302. By adjusting the knob 302, the bidirectional screw 304 can be rotated inside the third housing 301.

[0041] In a specific configuration, the outer surface of the bidirectional screw 304 is threaded with two sets of threaded seats 303. One side of the threaded seat 303 is connected to a clamping plate 305. One end of the clamping plate 305 penetrates the outer surface of the placement component 2015. The threaded seats 303 enable the bidirectional screw 304 to rotate, thereby moving the two sets of first threaded seats 303 and adjusting the distance between them. The movement of the first threaded seats 303 also causes the clamping plate 305 to move, and the two sets of clamping plates 305 fix one end of the tunnel boring machine cutter 6 inside the placement component 2015.

[0042] The working principle of this shield tunneling cutter wear quantitative detection device is as follows: When using the device, the motor 208 drives the circular plate 209 to rotate, which in turn drives the track component 2013 to rotate. When the sliding component 2017 is at the bottom of the first track 2016, it contacts the second track 2018. On the second track 2018, the sliding component 2017 slowly rises along the direction of the second track 2018. When the sliding component 2017 remains stationary, it is equivalent to driving the track component 2013 to slowly descend, compressing the spring 2011. When slider 2017 reaches above the first track 2016, it releases elastic potential energy through spring 2011 and moves downward along the vertical first track 2016. With slider 2017 stationary, this is equivalent to track 2013 rising. When track 2013 rotates, it drives the inner ring of bearing 2014 to rotate, while the outer ring of bearing 2014 does not rotate. As track 2013 moves up and down, it drives the outer ring of bearing 2014 to move up and down, causing the second guide plate 206 to slide inside the second housing 202. During the up and down movement of the outer ring of bearing 2014... The movement of the third rack plate 2022 causes the meshing first gear 2021 to rotate, thereby causing the second rack plate 2020 to move in the opposite direction to the third rack plate 2022. The second rack plate 2020 causes the first guide plate 205 to slide on the outer surface of the first guide rod 203. When the first guide plate 205 moves up and down, the second gear 2023 can rotate through the first rack plate 2019. This rotation, via the bearing 2014, causes the camera 5 to rotate, allowing the tunnel boring machine cutter 6 to move to its highest position, at which point the camera 5 can capture images of the bottom of the tunnel boring machine cutter 6. When the tunnel boring machine cutter 6 moves to the bottom, the camera 5 can capture the top of the cutter 6. When the cutter 6 is in the middle section, the camera 5 can capture the surrounding area of ​​the cutter 6. By controlling the adjustment knob 302, the bidirectional screw 304 is rotated inside the third housing 301, which moves the two sets of first threaded seats 303, thereby adjusting the distance between the two sets of first threaded seats 303. The movement of the first threaded seats 303 moves the clamping plate 305, and the two sets of clamping plates 305 fix one end of the cutter 6 inserted into the placement piece 2015.

[0043] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
