Description

Technical Field

[0001] This invention relates to the field of tunnel boring machines, and more particularly to a grouting device and a tunnel boring machine. Background Technology

[0002] During tunnel excavation, support segments are used to support the tunnel walls after excavation to ensure the stability and safety of the tunnel. In order to ensure a tight bond between the segments and the inner wall of the tunnel, as well as to repair defects such as cracks in the inner wall of the tunnel, grouting machines are generally used to inject cement grout or other fillers or adhesives between the segments and the inner wall of the tunnel, as well as into the cracks in the inner wall of the tunnel.

[0003] In the existing technology, the grouting machine is generally installed inside the tunnel boring machine. When the grouting machine is performing grouting operations, the tunnel boring machine needs to stop its tunneling operations first. Then, the injection head of the grouting machine passes through the through hole reserved in advance on the support segment and performs grouting operations between the segment and the inner wall of the tunnel. After the grouting work is completed, the tunnel boring machine resumes its tunneling operations.

[0004] However, this grouting method can only be carried out when the tunnel boring machine stops tunneling, resulting in low grouting efficiency. Summary of the Invention

[0005] To address at least one of the problems mentioned in the background art, the present invention provides a grouting device and a tunnel boring machine, which can perform grouting operations during the tunnel boring machine's excavation process, resulting in high grouting efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] In a first aspect, the present invention provides a grouting device for use on a tunnel boring machine (TBM), comprising a controller, a fixed frame, a telescopic assembly, a rotating assembly, and a grouting machine. The fixed frame is configured to be fixed to the bottom of a connecting bridge. The telescopic assembly includes a movable frame and a telescopic unit arranged sequentially along the tunneling direction of the TBM. The movable frame is movably connected to the fixed frame. One end of the telescopic unit is fixed to the fixed frame, and the other end of the telescopic unit is connected to the movable frame to drive the movable frame to move along the tunneling direction of the TBM through the telescopic movement of the telescopic unit. The controller is electrically connected to the telescopic unit and controls the telescopic unit to extend in the opposite direction as the TBM advances, so that the movable frame is maintained at its current position along the tunneling direction of the TBM. The rotating assembly is connected to the movable frame, and the grouting machine is connected to the rotating assembly. The rotating assembly is used to drive the grouting machine to rotate circumferentially along the TBM, and the grouting machine is used for drilling and grouting.

[0008] As an optional implementation, the telescopic unit is located in front of the moving frame, and the extension of the telescopic unit is configured to compensate for the propulsion stroke of the tunnel boring machine, wherein the front is aligned with the tunneling direction of the tunnel boring machine.

[0009] As an optional implementation, at least two telescopic units are arranged side by side at the bottom of the fixed frame.

[0010] As an alternative implementation, one of the bottom of the fixed frame and the top of the movable frame has a guide groove extending along the tunneling direction of the tunnel boring machine, and the other has a slide rail that matches the guide groove. The movable frame is slidably connected to the fixed frame via the slide rail or the guide groove.

[0011] As an optional implementation, the slewing assembly includes a slewing frame and a slewing unit. The slewing frame is fixedly connected to the bottom of the movable frame. The slewing frame includes an arc-shaped slewing body. The slewing direction of the slewing body is consistent with the circumferential direction of the tunnel boring machine. The slewing unit is disposed on the slewing body and can move along the slewing body. The grouting machine is connected to the slewing unit so that the grouting machine can be driven to rotate circumferentially along the tunnel boring machine through the slewing unit.

[0012] As an optional implementation, the rotating body has a first flange extending along the rotation axis of the rotating body, and the first flange is connected to opposite sides of the rotating body; the rotating unit includes a mounting frame and a guide wheel assembly, the mounting frame is disposed opposite to the first flange, and the guide wheel assembly includes a first guide wheel and a second guide wheel connected to the mounting frame, the first guide wheel and the second guide wheel respectively rolling against opposite sides of the first flange, so that the mounting frame moves along the surface of the first flange, and the grouting machine is connected to the mounting frame.

[0013] As an optional implementation, the rotary unit also includes a first motor and a transmission wheel. Both the first motor and the transmission wheel are mounted on the mounting frame. The first motor is connected to the transmission wheel, and the transmission wheel is connected to the rotary body in contact. Driven by the first motor, the transmission wheel drives the mounting frame to rotate along the rotation direction of the rotary body.

[0014] As an optional implementation, the rotating body also has a second flange connected to the radial outer side of the rotating body. The second flange has meshing teeth, and the transmission wheel is a gear that meshes with the meshing teeth. The gear drives the mounting frame to rotate along the rotation direction of the rotating body under the drive of the first motor.

[0015] As an optional implementation, the rotary unit also includes a second motor, which is mounted on the mounting frame. The grouting machine is connected to the second motor for transmission, so that the second motor drives the grouting machine to rotate circumferentially along the tunnel boring machine.

[0016] In a second aspect, the present invention also provides a tunnel boring machine, including any of the grouting devices described in the first aspect.

[0017] The grouting device provided by this invention is applied to a tunnel boring machine. The grouting device includes a controller, a fixed frame, a telescopic assembly, a rotating assembly, and a grouting machine. The fixed frame is constructed to be fixed to the bottom of a connecting bridge. The telescopic assembly includes a movable frame and a telescopic unit arranged sequentially along the tunnel boring machine's excavation direction. The movable frame is movably connected to the fixed frame. One end of the telescopic unit is fixed to the fixed frame, and the other end of the telescopic unit is connected to the movable frame. The telescopic unit's extension and retraction drive the movable frame to move along the tunnel boring machine's excavation direction. The controller is electrically connected to the telescopic unit and controls the telescopic unit to extend in the opposite direction as the tunnel boring machine advances, so that the movable frame remains at its current position along the tunnel boring machine's excavation direction. The rotating assembly is connected to the movable frame, and the grouting machine is connected to the rotating assembly. The rotating assembly drives the grouting machine to rotate circumferentially along the tunnel boring machine. The grouting machine is used for drilling and grouting. When the grouting device provided by this invention is in use, the controller can control the telescopic unit to extend in the opposite direction as the tunnel boring machine advances. The telescopic unit pushes the moving frame connected to the telescopic unit away in the opposite direction of the tunnel boring machine's excavation by extending the telescopic unit. The moving frame drives the rotating component to move together with the grouting machine to ensure that the grouting machine maintains a stationary relative position with the support segments and the inner wall of the tunnel. This ensures that the grouting machine can continue to perform normal grouting operations at the current position even during the tunnel boring machine's excavation process, thus improving the efficiency of the grouting operation.

[0049] In the existing technology, the grouting machine is generally installed inside the tunnel boring machine. When the grouting machine is performing grouting operations, the tunnel boring machine needs to stop its tunneling operations first. Then, the injection head of the grouting machine passes through the through hole reserved in advance on the support segment and performs grouting operations between the segment and the inner wall of the tunnel. After the grouting work is completed, the tunnel boring machine resumes its tunneling operations.

[0050] In view of this, the present invention provides a grouting device for use on a tunnel boring machine. The grouting device includes a controller, a fixed frame, a telescopic assembly, a rotating assembly, and a grouting machine. The fixed frame is configured to be fixed to the bottom of a connecting bridge. The telescopic assembly includes a movable frame and a telescopic unit arranged sequentially along the tunneling direction of the tunnel boring machine. The movable frame is movably connected to the fixed frame. One end of the telescopic unit is fixed to the fixed frame, and the other end of the telescopic unit is connected to the movable frame so that the movable frame can be moved along the tunneling direction of the tunnel boring machine by telescoping. The controller is electrically connected to the telescopic unit and controls the telescopic unit to extend in the opposite direction as the tunnel boring machine advances, so that the movable frame is maintained at its current position along the tunneling direction of the tunnel boring machine.

The rotating assembly is used to drive the grouting machine to rotate circumferentially along the tunnel boring machine. The grouting machine is used for drilling and grouting. When the grouting device provided by this invention is in use, the controller can control the telescopic unit to extend in the opposite direction as the tunnel boring machine advances. The telescopic unit pushes the moving frame connected to the telescopic unit away in the opposite direction of the tunnel boring machine's excavation by extending the telescopic unit. The moving frame drives the rotating component to move together with the grouting machine to ensure that the grouting machine maintains a stationary relative position with the support segments and the inner wall of the tunnel. This ensures that the grouting machine can continue to perform normal grouting operations at the current position even during the tunnel boring machine's excavation process, thus improving the efficiency of the grouting operation.

[0051] Figure 1 This is a schematic diagram of the structure of a tunnel boring machine provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of the structure of a grouting device provided in an embodiment of the present invention; Figure 3 for Figure 2 The left view; Figure 4 for Figure 3 AA sectional view. (For reference) Figures 1 to 4This invention provides a grouting device 100, applied to a tunnel boring machine 200, including a controller, a fixed frame 110, a telescopic assembly 120, a rotating assembly 130, and a grouting machine 140. The fixed frame 110 is configured to be fixed to the bottom of a connecting bridge. The telescopic assembly 120 includes a movable frame 121 and a telescopic unit 122 arranged sequentially along the tunneling direction of the tunnel boring machine 200. The movable frame 121 is movably connected to the fixed frame 110. One end of the telescopic unit 122 is fixed to the fixed frame 110, and the other end of the telescopic unit 122 is connected to the movable frame 121 to allow for... The telescopic drive mobile frame 121 of the telescopic unit 122 moves along the tunneling direction of the tunnel boring machine 200. The controller is electrically connected to the telescopic unit 122 and controls the telescopic unit 122 to extend in the opposite direction as the tunnel boring machine 200 advances, so that the mobile frame 121 is maintained at its current position along the tunneling direction of the tunnel boring machine 200. The slewing assembly 130 is connected to the mobile frame 121, and the grouting machine 140 is connected to the slewing assembly 130. The slewing assembly 130 is used to drive the grouting machine 140 to rotate circumferentially along the tunnel boring machine 200. The grouting machine 140 is used for drilling and grouting.

[0052] When the grouting device 100 provided in this embodiment of the invention is in use, the controller can control the telescopic unit 122 to extend in the opposite direction as the tunnel boring machine 200 advances. The telescopic unit 122 extends and pushes the movable frame 121 connected to the telescopic unit 122 away in the opposite direction to the tunnel boring machine's excavation. The movable frame 121 drives the rotating assembly 130 to move together with the grouting machine 140, so as to ensure that the grouting machine 140 remains stationary relative to the support segments and the inner wall of the tunnel. This ensures that the grouting machine 140 can continue to perform normal grouting operations at the current position even during the tunnel boring machine 200's excavation, thus improving the efficiency of the grouting operation.

[0053] In the above embodiments, specifically, the telescopic unit 122 can be located in front of the moving frame 121. The extension of the telescopic unit 122 is configured to compensate for the propulsion stroke of the tunnel boring machine 200, wherein the front is consistent with the tunneling direction of the tunnel boring machine 200. It can be understood that, under the control of the controller, it can be ensured that the distance the tunnel boring machine excavates forward is always equal to the distance the telescopic unit 122 pushes the moving frame 121 backward. In this way, the moving frame 121 can be kept relatively stationary with respect to the support segments and the tunnel inner wall, so that the injection head of the grouting machine 140 connected to the connecting frame can maintain the state of passing through the through hole on the current segment for normal operation.

[0054] In the above embodiments, there may be at least two telescopic units 122. At least two telescopic units 122 are arranged side by side at the bottom of the fixed frame 110. The telescopic ends of the two telescopic units 122 can be connected to the movable frame 121. The two telescopic units 122 can telescopically extend and retract under the control of the same controller, and together drive the movable frame 121 to move along the bottom of the fixed frame 110.

[0055] In the above embodiments, there are various ways to set up the mobile frame 121 and the fixed frame 110. For example, a guide groove extending along the tunneling direction of the tunnel boring machine 200 can be set at the bottom of the fixed frame 110, and a slide rail can be set at the top of the mobile frame 121.

[0056] Alternatively, a slide rail extending along the tunneling direction of the tunnel boring machine 200 can be provided at the bottom of the fixed frame 110, and a guide groove can be provided at the top of the movable frame 121. The movable frame 121 is slidably connected to the fixed frame 110 through the slide rail or guide groove.

[0057] In the above embodiments, the slewing assembly 130 may include a slewing frame and a slewing unit 132. The slewing frame is fixedly connected to the bottom of the movable frame 121. The slewing frame includes an arc-shaped slewing body 131, the slewing direction of which is consistent with the circumferential direction of the tunnel boring machine 200. The slewing unit 132 is disposed on the slewing body 131 and can move along the slewing body 131. The grouting machine 140 is connected to the slewing unit 132 so that the grouting machine 140 can be driven to rotate circumferentially along the tunnel boring machine 200 through the slewing unit 132. Figure 3 As shown, the arc-shaped trajectory of the rotating body 131 can be consistent with the circumference of the tunnel inner wall. Thus, when the rotating unit 132 moves along the arc-shaped rotating body 131, the rotating unit 132 also rotates along the circumference of the tunnel. As a result, the rotating unit 132 drives the grouting machine 140 to rotate along the circumference of the tunnel boring machine 200, thereby controlling the grouting machine 140 to perform grouting operations at different parts of the tunnel inner wall.

[0058] In the above embodiment, the rotating body 131 has a first flange 1311 extending along the rotation axis of the rotating body 131, and the first flange 1311 is connected to opposite sides of the rotating body 131; the rotating unit 132 includes a mounting frame 1321 and a guide wheel assembly 1322, the mounting frame 1321 is disposed opposite to the first flange 1311, and the guide wheel assembly 1322 includes a first guide wheel 13221 and a second guide wheel 13222 connected to the mounting frame 1321, the first guide wheel 13221 and the second guide wheel 13222 respectively rolling against opposite sides of the first flange 1311, so that the mounting frame 1321 moves along the surface of the first flange 1311, and the grouting machine 140 is connected to the mounting frame 1321. Figure 3As shown, the first guide wheel 13221 and the second guide wheel 13222 can clamp the first flange 1311 in the middle. On the one hand, the first guide wheel 13221 and the second guide wheel 13222 can ensure a stable connection between the mounting frame 1321 and the rotating body 131. On the other hand, the first guide wheel 13221 and the second guide wheel 13222 can roll along both sides of the first flange 1311 to drive the grouting machine 140 connected to the mounting frame 1321 to rotate.

[0059] In the above embodiment, the rotary unit 132 further includes a first motor 1323 and a transmission wheel. Both the first motor 1323 and the transmission wheel are mounted on the mounting frame 1321. The first motor 1323 is connected to the transmission wheel, and the transmission wheel is in contact with the rotary body 131. Driven by the first motor 1323, the transmission wheel drives the mounting frame 1321 to rotate along the rotation direction of the rotary body 131. It can be understood that when the first motor 1323 rotates, the transmission wheel, which is connected to the first motor 1323, rotates together, and the transmission wheel drives the mounting frame 1321 to rotate along the rotation direction (arc-shaped edge) of the rotary body 131.

[0060] There are various ways to connect the transmission wheel and the rotating body 131. For example, the rotating body 131 may also have a second flange 1312, which is connected to the radial outer side of the rotating body 131. The second flange 1312 has meshing teeth 13121, and the transmission wheel is a gear 1324 that meshes with the meshing teeth 13121. The gear 1324, driven by the first motor 1323, drives the mounting frame 1321 to rotate along the rotation direction of the rotating body 131. Specifically, when the first motor 1323 rotates, it drives the gear 1324 to roll along the extension direction of the meshing teeth 13121, thereby driving the entire mounting frame 1321 and the grouting machine 140 to rotate along the arc-shaped trajectory of the arc-shaped rotating body 131.

[0061] In the above embodiments, the rotary unit 132 may further include a second motor 1325, which is mounted on the mounting frame 1321. The grouting machine 140 is connected to the second motor 1325 for transmission, so that the second motor 1325 drives the grouting machine 140 to rotate circumferentially along the tunnel boring machine 200. It can be understood that when the mounting frame 1321 and the grouting machine 140 rotate along the arc-shaped trajectory of the arc-shaped rotary body 131, the grouting machine 140 can also rotate circumferentially along the tunnel under the drive of the second motor 1325. In this way, the position rotation of the grouting machine 140 can be more flexible, and the working range of the grouting machine 140 in the tunnel can be expanded.

[0062] The grouting device 100 provided in this embodiment of the invention is applied to a tunnel boring machine 200. The grouting device 100 includes a controller, a fixed frame 110, a telescopic assembly 120, a rotating assembly 130, and a grouting machine 140. The fixed frame 110 is configured to be fixed to the bottom of the connecting bridge. The telescopic assembly 120 includes a movable frame 121 and a telescopic unit 122 arranged sequentially along the tunneling direction of the tunnel boring machine 200. The movable frame 121 is movably connected to the fixed frame 110. One end of the telescopic unit 122 is fixed to the fixed frame 110, and the other end of the telescopic unit 122 is connected to the movable frame 121. The telescopic unit 122 drives the moving frame 121 to move along the tunneling direction of the tunnel boring machine 200. The controller is electrically connected to the telescopic unit 122 and controls the telescopic unit 122 to extend in the opposite direction as the tunnel boring machine 200 advances, so that the moving frame 121 is maintained at its current position along the tunneling direction of the tunnel boring machine 200. The slewing assembly 130 is connected to the moving frame 121, and the grouting machine 140 is connected to the slewing assembly 130. The slewing assembly 130 is used to drive the grouting machine 140 to rotate circumferentially along the tunnel boring machine 200. The grouting machine 140 is used for drilling and grouting. When the grouting device 100 provided in this embodiment of the invention is in use, the controller can control the telescopic unit 122 to extend in the opposite direction as the tunnel boring machine 200 advances. The telescopic unit 122 extends and pushes the movable frame 121 connected to the telescopic unit 122 away in the opposite direction to the tunnel boring machine's excavation. The movable frame 121 drives the rotating assembly 130 to move together with the grouting machine 140, so as to ensure that the grouting machine 140 remains stationary relative to the support segments and the inner wall of the tunnel. This ensures that the grouting machine 140 can continue to perform normal grouting operations at the current position even during the tunnel boring machine 200's excavation, thus improving the efficiency of the grouting operation.

[0063] Furthermore, this embodiment of the invention also provides a tunnel boring machine 200, including any of the grouting devices 100 in the above embodiments. The grouting device 100 includes a controller, a fixed frame 110, a telescopic assembly 120, a rotating assembly 130, and a grouting machine 140.

The telescopic assembly 120 includes a movable frame 121 and a telescopic unit 122 arranged sequentially along the tunneling direction of the tunnel boring machine 200. The movable frame 121 is movably connected to the fixed frame 110. One end of the telescopic unit 122 is fixed to the fixed frame 110, and the other end of the telescopic unit 122 is connected to... The mobile frame 121 is connected to the telescopic unit 122, which drives the mobile frame 121 to move along the tunneling direction of the tunnel boring machine 200. The controller is electrically connected to the telescopic unit 122 and controls the telescopic unit 122 to extend in the opposite direction as the tunnel boring machine 200 advances, so that the mobile frame 121 is maintained at its current position along the tunneling direction of the tunnel boring machine 200. The slewing assembly 130 is connected to the mobile frame 121, and the grouting machine 140 is connected to the slewing assembly 130. The slewing assembly 130 is used to drive the grouting machine 140 to rotate circumferentially along the tunnel boring machine 200. The grouting machine 140 is used for drilling and grouting. When the grouting device 100 provided in this embodiment of the invention is in use, the controller can control the telescopic unit 122 to extend in the opposite direction as the tunnel boring machine 200 advances. The telescopic unit 122 extends and pushes the movable frame 121 connected to the telescopic unit 122 away in the opposite direction to the tunnel boring machine's excavation. The movable frame 121 drives the rotating component 130 to move together with the grouting machine 140 to ensure that the grouting machine 140 remains stationary relative to the support segments and the tunnel inner wall. This ensures that the grouting machine 140 can continue to perform normal grouting operations at the current position even during the tunnel boring machine 200's excavation process, thereby improving the operating efficiency of the grouting machine 140 and the tunnel boring machine 200.
