[0002] A shield machine is a tunnel boring machine that uses the shield method. After the shield machine is formed, the inner wall detection is an important step to ensure the safety and quality of the tunnel structure. This work usually involves the use of a variety of detection technologies that can help engineers evaluate the integrity of the tunnel wall and detect potential defects such as voids, cracks and uneven settlement.

[0003] After the existing subway tunnel is formed and before the tunnel facilities and tracks are laid, the integrity of the tunnel inner wall needs to be detected. The subway tunnel is usually an annular cavity. Due to its large size, it is necessary to set up a ladder during the detection to detect whether the joints of the tunnel tiles are flat and whether the tile holes are fully filled.

[0004] The workers need to climb on the ladder, which is a certain height, resulting in certain safety hazards during the detection process. In addition, due to the long length of the tunnel, setting up and moving the ladder also affects the detection efficiency to a certain extent.

[0043] like Figure 1-Figure 4 As shown, the present invention provides an advance detection device for shield equipment, including a bearing mechanism, a driving mechanism, a first detection mechanism 4 and a second detection mechanism 6; the bearing mechanism includes a bearing member 2, a first mounting member 3, a second mounting member 5 and a connecting member 302, the connecting member 302 is rotatably connected to the bearing member 2, the two ends of the connecting member 302 are respectively connected to the first mounting member 3 and the second mounting member 5, the driving mechanism is connected to the second mounting member 5, so that the first mounting member 3 and the second mounting member 5 can rotate relative to the bearing member 2; the first detection mechanism 4 is arranged on the first mounting member 3, and the second detection mechanism 6 is arranged on the second mounting member 5, the first detection mechanism 4 includes a first rebound member 404, the second detection mechanism 6 includes a second rebound member 604, the first rebound member 404 and the second rebound member 604 both extend radially along the bearing member 2, and one end of the first rebound member 404 and the second rebound member 604 both protrude from the outer circumference of the bearing member 2 and can shrink radially.

[0044] Compared with the prior art, the shield equipment advance detection device provided by the present invention has the following advantages:

[0045] The shield equipment advance detection device provided by the present invention can be connected to the shield equipment through the connecting piece 302, and the load-bearing component 2 can provide an installation basis for the driving mechanism. Moreover, since the driving mechanism in the present application is connected to the second mounting component 5, the second mounting component 5 can be driven to rotate.

[0046] It can be understood that, since the second mounting component 5 in the present application is connected to one end of the connecting member 302, and the other end of the connecting member 302 is connected to the first mounting component 3, when the second mounting component 5 rotates under the action of the driving mechanism, it can drive the connecting member 302 to rotate, thereby driving the first mounting component 3 to rotate.

[0047] Since the first detection mechanism 4 is disposed on the first mounting member 3 and the second detection mechanism 6 is disposed on the second mounting member 5 , the first detection mechanism 4 and the second detection mechanism 6 can rotate synchronously.

[0048] In addition, the first detection mechanism 4 in the present application includes a first rebound member 404, the second detection mechanism 6 includes a second rebound member 604, and one end of the first rebound member 404 and the second rebound member 604 both protrude from the outer ring circumference of the bearing member 2 and can shrink radially. Therefore, in actual application, the first rebound member 404 and the second rebound member 604 are always in contact with the inner wall of the tunnel. When the shield equipment starts to move along the tunnel, the first mounting member 3 and the second mounting member 5 start to rotate, driving the first rebound member 404 and the second rebound member 604 to scan the inner wall of the tunnel.

[0049] When there is a pit on the inner wall of the tunnel, the compressed first resilient member 404 or the second resilient member 604 is released to a certain extent at the pit and contacts the lowest point of the pit, thereby generating a knocking sound in the process. The knocking sound can then be used to detect the presence of a pit at the corresponding position, thereby realizing scanning and detection of the flatness of the inner wall.

[0050] In actual application of this embodiment, one end of the connecting piece 302 is directly connected to the shield equipment, so that it can move synchronously with the shield equipment, and is connected to the tail of the shield equipment and located at the center of the shield equipment, so that it can be located at the center of the tunnel to ensure the detection effect.

[0051] The detection of the tunnel by the advance detection device of the shield equipment can ensure the scanning and detection of the flatness of the inner wall of the tunnel before the shield excavation, thereby ensuring safe and reliable excavation during the shield process.

[0052] It should be noted here that, in the present embodiment, the driving mechanism may be a motor, and since the second mounting member 5 is connected to the connecting member 302, it also has a rotation center, and the motor may be connected to the rotation center, that is, a driving shaft and other structures may be added to realize the connection with the second mounting member 5. At the same time, the driving mechanism drives the driving shaft to rotate, thereby driving the second mounting member 5, thereby synchronously driving the connecting member 302 and the first mounting member 3 to rotate, thereby realizing the detection of the tunnel.

[0053] Alternatively, if Figure 1 Combination Figure 6 and Figure 7As shown, the driving mechanism includes a first driving component and a second driving component; the first driving component includes a plurality of friction wheels 7, and the plurality of friction wheels 7 are arranged at intervals along the circumference of the load-bearing member 2, and the second driving component includes a transmission member and an engaging member; a meshing portion 5011 is formed on the side of the second mounting member 5 facing the load-bearing member 2, and the meshing portion 5011 is arranged along the circumference of the second mounting member 5; the transmission member is connected to one of the friction wheels 7, the transmission member is meshed with the engaging member, and the engaging member is meshed with the engaging portion 5011, so that the second mounting member 5 can rotate relative to the load-bearing member 2.

[0054] Parts of the multiple friction wheels 7 of the present application protrude from the outer wall of the load-bearing member 2 so that they can contact the inner wall of the tunnel. The load-bearing member 2 and the connecting member 302 can be connected and installed through a bearing, that is, the inner ring of the bearing is fixedly connected to the connecting member 302, and the outer ring is fixedly connected to the load-bearing member 2, so that when the connecting member 302 rotates, it can rotate relative to the load-bearing member 2.

[0055] Therefore, in this embodiment, when the shield equipment moves forward, the friction wheel 7 in contact with the inner wall of the tunnel can rotate, and the present application can rotate with the friction wheel 7 by further providing a rotating member 203 connected to the friction wheel 7. Since the rotating member 203 is engaged with the engaging member, power can be transmitted to the engaging member.

[0056] In this embodiment, by further arranging the meshing portion 5011 in the circumferential direction of the second mounting component 5, and the meshing piece meshing with the meshing portion 5011, when the meshing piece rotates, the rotation of the second mounting component 5 can be realized through the meshing, and then the rotation of the first mounting component 3 can be realized through the connecting piece 302, and finally the synchronous rotation of the first detection mechanism 4 and the second detection mechanism 6 is realized, so as to realize the detection of the tunnel.

[0057] It should be noted here that, in the present embodiment, by arranging the friction wheel 7 on the load-bearing member 2, the forward power of the shield equipment can be converted into the rotational power of the first mounting member 3 and the second mounting member 5. Therefore, there is no need to set up other power sources, which greatly saves space occupancy and manufacturing costs. In addition, there is no need for complex control design, which makes the structure simpler and reduces maintenance costs.

[0058] Preferably, in this embodiment, the transmission member is a worm 8, the engaging member is a worm wheel 9, the first drive assembly also includes a first rotating shaft and a second rotating shaft, the first rotating shaft and the second rotating shaft are both connected to the friction wheel 7, the worm 8 is correspondingly sleeved on the first rotating shaft and the second rotating shaft, and the transmission member and the engaging member are arranged one by one.

[0059] By providing the first rotating shaft and the second rotating shaft, two worm gears 8 can be provided on both sides of the friction wheel 7 to improve power output and stability.

[0060] Accordingly, if Figure 1 Combination Figure 6 and Figure 7 As shown, in the present application, the two friction wheels 7 located at the top and bottom of the bearing member 2 are connected to the first rotating shaft and the second rotating shaft, thereby further improving the power output and the stability of the overall equipment operation.

[0061] Further preferably, the bearing member 2 in the present application comprises a main ring body 201, and the main ring body 201 is formed with avoidance portions 2011 at positions corresponding to the top and bottom friction wheels 7, and the avoidance portions 2011 can meet the arrangement and installation of the worm 8 and the worm wheel 9. In addition, a mounting portion 2012 is also provided on the outer wall of the main ring body 201 at a position corresponding to the avoidance portion 2011, and the mounting portion 2012 can be used to achieve stable installation of the first rotating shaft and the second rotating shaft, and a bearing can be provided on the mounting portion 2012 to achieve the rotation of the first rotating shaft and the second rotating shaft relative to the mounting portion 2012.

[0062] It is understandable that, since the worm wheel 9 also needs to rotate, a mounting rod 2013 can be further provided on the inner wall of the bearing member 2 and at a position corresponding to the worm wheel 9, so that the worm wheel 9 is rotationally connected to the mounting rod 2013, thereby enabling stable transmission of power of the overall device.

[0063] Alternatively, if Figure 1-Figure 4 As shown, in the present application, the first mounting component 3 includes a connecting plate 3021, a basic sleeve 301 and a mounting plate 303; there are multiple connecting plates 3021, which are arranged at circumferential intervals around the connecting member 302, one end of the connecting plate 3021 is connected to the outer wall of the connecting member 302, the basic sleeve 301 is concentrically arranged with the connecting member 302, and the other end of the connecting plate 3021 is connected to the inner wall of the basic sleeve 301; there are multiple mounting plates 303, and one end of the multiple mounting plates 303 are all connected to the other end of the basic sleeve 301, the multiple mounting plates 303 are arranged at circumferential intervals along the basic sleeve 301, and the first rebound members 404 are arranged on the mounting plates 303 in a one-to-one correspondence.

[0064] The connecting plate 3021 and the mounting plate 303 in the present application are both radially and divergently arranged. The connecting plate 3021 can achieve a stable connection between the basic sleeve 301 and the connecting member 302, and the mounting plate 303 can provide a stable installation position for the first resilient member 404.

[0065] Furthermore, in this embodiment, a bearing can be installed on the outer wall of the basic sleeve 301, so that the outer ring of the bearing is fixedly connected to the bearing member 2, thereby enabling the basic sleeve 301 to rotate relative to the bearing member 2. Of course, since the bearing member 2 is provided with a friction wheel 7, the bearing can be arranged in a manner avoiding the friction wheel 7 in the axial direction of the bearing member 2, thereby avoiding the problem of interference.

[0066] Based on the above structure, Figure 1-Figure 4 As shown, the first detection mechanism 4 in the present application also includes a first positioning block 401 and a first elastic member 402; the first positioning block 401 is arranged in a one-to-one correspondence with the mounting plate 303, the first positioning block 401 forms a first accommodating cavity, the first elastic member 402 is arranged in the first accommodating cavity, and one end of the first rebound member 404 is located in the first accommodating cavity and is connected to the first elastic member 402.

[0067] The first positioning block 401 in the present application is arranged on the mounting plate 303, and the first elastic member 402 is a spring, which is arranged in the first accommodating cavity formed by the first positioning block 401, so that by setting one end of the first resilient member 404 in the first accommodating cavity and connecting with the first elastic member 402, the automatic rebound of the first resilient member 404 can be achieved. In actual operation, the circumferential diameter formed by one end of multiple first resilient members 404 away from the first elastic member 402 is larger than the inner wall diameter of the tunnel. Therefore, the first resilient member 404 is always in a contracted state, that is, the first elastic member 402 is always in a compressed state.

[0068] When encountering a hole pit during the rotation process, the first resilient member 404 can enter the hole pit, so that under the action of the first elastic member 402, the end of the first resilient member 404 hits the bottom of the hole, which will produce a collision sound, reminding the detection personnel that there is a hole at the corresponding position and it needs to be repaired.

[0069] It should be noted here that the first resilient member 404 in the present application is in a cylindrical structure. Since the interior of the circular tunnel is spliced ​​by multiple tiles, multiple holes are usually provided on the tiles. In some cases, the holes may need to be poured with concrete to provide additional structural support and sealing. The holes need to be poured with concrete to form a solid boundary to prevent water intrusion or soil loss. It also helps to fix the tunnel tiles themselves. However, after the holes are poured and filled, the flatness of the tile surface after filling needs to be maintained. Therefore, by making the first resilient member 404 in a cylindrical structure, it can be adapted to the diameter of the hole to complete the detection of the integrity of the hole filling.

[0070] Preferably, if Figure 4 As shown, the first detection mechanism 4 in the present application also includes a first movable part 403 and a first detection circle 405. A first guide opening 4011 is formed on the outer wall of the first positioning block 401. The first guide opening 4011 extends radially along the base sleeve 301. One end of the first movable part 403 passes through the first guide opening 4011 and is connected to the first elastic part 402. The first detection circle 405 is connected to the other end of the first movable part 403.

[0071] By forming a first guide opening 4011 on the outer wall of the first positioning block 401, a basis can be provided for connecting the first movable member 403 with one end of the first resilient member 404. Since the first movable member 403 is connected to the first resilient member 404, during the movement of the first resilient member 404, the first movable member 403 can provide auxiliary guiding function for the first resilient member 404, so that the movement of the first resilient member 404 is more stable.

[0072] Furthermore, by further connecting the first detection circle 405 to the first movable member 403, and since there are multiple first movable members 403 in the present application, the first detection circle 405 can be in a complete circle. However, in actual operation, since the first resilient member 404 abuts against the inner wall of the tunnel to produce a certain degree of retraction, the first detection circle 405 can be formed at the position corresponding to the first movable member 403. Figure 5 When encountering a hole, since the first resilient member 404 can enter the hole, the depression can be restored, thereby more obviously reminding the detection personnel that there is a hole in the corresponding area, thereby ensuring the detection accuracy.

[0073] Alternatively, if Figure 1-Figure 4 As shown, the shield equipment advance detection device provided by the present invention also includes a docking member 1, a second mounting member 5 is connected to the end of the base sleeve 301, a rotating member 203 is sleeved on the middle position of the base sleeve 301 on the axis, and the base sleeve 301 is rotatably connected to the rotating member 203, and a support portion 202 is connected between the outer wall of the rotating member 203 and the inner wall of the bearing member 2.

[0074] The rotating member 203 in the present application can be a bearing. In the present embodiment, by setting the rotating member 203 on the inner wall of the base sleeve 301 and connecting it with the load-bearing member 2 using the support portion 202, the inner wall space of the load-bearing member 2 can be freed up, making the setting space of the friction wheel 7 more sufficient and improving the stability of the overall structure.

[0075] It should be additionally explained here that one end of the connecting member 302 in the present application is connected to the docking member 1, and the docking member 1 can be used to achieve a quick connection with the shield equipment.

[0076] Alternatively, if Figure 3 As shown, the second mounting component 5 in the present application includes a turntable 501 , which is connected to the end of the base sleeve 301 , and the second detection mechanism 6 is arranged on a side of the turntable 501 away from the base sleeve 301 .

[0077] The turntable 501 can provide sufficient space for the arrangement of the second detection mechanism 6 and provide a basis for the arrangement of the meshing portion 5011, thereby realizing the rotation of the entire device.

[0078] Alternatively, if Figure 3 As shown, the second detection mechanism 6 in the present application also includes a second positioning block 601 and a second elastic member 602; there are multiple second positioning blocks 601, and the multiple second positioning blocks 601 are evenly distributed along the circumferential direction of the turntable 501, and the axes of the multiple second positioning blocks 601 extend radially along the turntable 501; the second positioning block 601 forms a second accommodating cavity, the second elastic member 602 is arranged in the second accommodating cavity, and one end of the first rebound member 404 is located in the second accommodating cavity and is connected to the second elastic member 602.

[0079] The installation and connection method of the second positioning block 601, the second elastic member 602 and the second resilient member 604 in the present application are the same as the installation and connection method of the first positioning block 401, the first elastic member 402 and the first resilient member 404, and the detection process is also the same, which will not be repeated here.

[0080] Correspondingly, such as Figure 3 As shown, the second detection mechanism 6 in the present application also includes a second movable member 603 and a second detection circle 605. A second guide opening 6011 is formed on the outer wall of the second positioning block 601. The second guide opening 6011 extends radially along the turntable 501. One end of the second movable member 603 passes through the second guide opening 6011 and is connected to the second elastic member 602. The second detection circle 605 is connected to the other end of the second movable member 603.

[0081] Preferably, the second resilient member 604 in the present application is further provided with an arc block 6041 at one end away from the second elastic member 602. After the tunnel is excavated, tiles need to be spliced ​​and concrete needs to be filled between the tiles and the soil. In this process, there may be inconsistencies in the concrete filled between each tile and the soil, which will cause the inner wall of the circular tunnel formed by the tiles to be uneven and depressions to exist at the joints between each tile. The arc block 6041 can increase the contact area with the tiles, so that the depressions between adjacent tiles can be better fed back, and then the second detection circle 605 connected to the second movable member 603 can be used to detect and feedback the depressions, so that the detection personnel can better obtain the location of the depressions and ensure the detection effect.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
