Description

Technical Field

[0001] This invention relates to a shield tunnel segment assembly device, belonging to the field of shield tunneling machine technology. Background Technology

[0002] A tunnel boring machine (TBM), or shield tunneling machine for short, is a specialized engineering machine for tunnel excavation. After the tunnel is excavated, ring-shaped shield segments are assembled inside the tunnel. However, existing assembly equipment uses a robotic arm to grab and assemble the shield segments. The assembly sequence starts with the lower standard segments, then alternates between the left and right sides, and adjacent segments are locked with bolts. Finally, the top segment is installed. This process requires the robotic arm to swing frequently and significantly left and right to place multiple shield segments into a ring, which is time-consuming. Furthermore, it is necessary to pre-lock the adjacent segments on both sides to prevent the top segment from falling before assembling the top segment, further increasing the assembly time and resulting in low assembly efficiency. After assembly, as the TBM continues to excavate and exits the shield tail, the assembled shield segments deform under the pressure of the earth. At this time, the pre-locked bolts loosen, requiring secondary tightening, which is inconvenient and further affects the assembly efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a shield tunnel segment assembly device to solve the technical problems existing in the prior art.

[0007] In the aforementioned shield tunnel segment assembly equipment, the clamping component includes a carrier ring coaxially disposed on the outer side of the inner top ring. Multiple top rods are elastically installed in a ring array on the outer surface of the carrier ring. A top seat is fixedly installed at one end of the top rod corresponding to the inner wall of the assembly ring. A rubber pad is installed at one end of the top seat corresponding to the inner wall of the assembly ring. The other end of the top rod is semi-circular and is attached to the outer surface of the inner top ring.

[0008] In the aforementioned shield tunnel segment assembly equipment, the front and rear ends of the top rod both extend with protruding seats near the other end. A return spring is fixedly installed at the lower end of the protruding seat. The lower end of the return spring is fixedly connected to the inner wall of the carrier ring. A gear ring is fixedly installed coaxially on the rear end face of the carrier ring. Three motor frames are fixedly installed in a ring array on the rear end face of the inner top ring. A servo motor with a brake is fixedly installed at the end of the motor frame. A gear is coaxially embedded at the output end of the servo motor with the brake, and the gear meshes with the gear ring.

[0009] In the aforementioned shield tunnel segment assembly equipment, the pulling component includes five No. 1 servo push cylinders fixedly installed in a ring array on the inner wall of the shield machine shell. The No. 1 servo push cylinder is located in front of the assembly ring. A connecting frame is fixedly installed at the output end of the No. 1 servo push cylinder. A bearing ring is fixedly installed at the front part of the guide rod. A No. 2 connecting ring is rotatably connected to the front end of the bearing ring. A No. 1 connecting ring is rotatably connected to the front edge of the outer surface of the bearing ring. A No. 1 fixing column is fixedly installed on the front end face of the No. 1 connecting ring. A No. 2 fixing column is fixedly installed on the front end face of the inner top ring. The No. 2 connecting ring, the No. 1 fixing column, and the No. 2 fixing column are all fixedly connected to the connecting frame.

[0012] The beneficial effects of the present invention: Compared with the prior art, the present invention has the following advantages:

[0013] 1. By using the assembly ring, after placing the shield tunnel segment on the lower inner side of the assembly ring, the rotating assembly ring causes the shield tunnel segment to move at a certain angle and be misaligned with the lower part of the assembly ring. Then the assembly ring stops rotating, and another shield tunnel segment is placed on the lower inner side of the assembly ring. The assembly ring then continues to rotate, and so on, assembling multiple shield tunnel segments into a ring shape at once. This avoids the time wasted by the back-and-forth swinging of the robotic arm and pre-locking, thus effectively improving the assembly efficiency.

[0014] 2. During the rotation of the assembly ring, the carrier ring will rotate synchronously. At this time, the top rods originally located in the recessed part of the inner top ring on the carrier ring will slide along the outer wall of the inner top ring and be pushed out, so that the top seat on the top rod can press tightly onto the shield tunnel segment, thereby pressing the shield tunnel segment tightly onto the assembly ring, thus ensuring that the shield tunnel segment can rotate stably with the assembly ring and preventing the shield tunnel segment from falling off.

[0015] 3. After the tunnel segments are assembled into a ring shape, the No. 1 servo pusher cylinder moves, driving the connecting frame forward. At this time, the moving connecting frame will simultaneously drive the inner top ring and the carrier ring forward, so that the top rods pressing on the tunnel segments on the carrier ring can be pulled out, allowing multiple tunnel segments to converge under the action of gravity. During the forward movement of the connecting frame, the guide rod will also move forward. At this time, the plunger slides in the guide sleeve to push the gas in the guide sleeve into the jacking pipe, so that the top rod on the jacking pipe is pushed out by the gas, and then pushes out the extrusion seat to extrude the tunnel segments from the outside, so that the multiple tunnel segments assembled into a ring shape can be tightly locked together, thus achieving the purpose of locking in one go, effectively improving the convenience of locking and further improving the assembly efficiency.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0026] An embodiment of the present invention: a shield tunnel segment assembly device, such as... Figures 1-8As shown, the shield machine includes a shield housing 1. An assembly ring 2 is rotatably mounted through the inner wall of the shield housing 1. A rubber ring 3 is fixedly mounted on the inner wall of the assembly ring 2. A pneumatic extrusion component is also installed through the inner wall of the assembly ring 2, penetrating the inner wall of the rubber ring 3. The rubber ring 3 serves to protect the shield tunnel segments. A pulling component is installed in front of the assembly ring 2 on the inner wall of the shield housing 1. A top claw 28 is embedded at the front edge of the inner wall of the assembly ring 2. The top claw 28 is used to extrude the shield tunnel segments when the top rod 16 is pulled out. The blocking effect prevents the shield tunnel segments from being pulled out by the top rod 16. An inner top ring 10 is provided in the middle of the inner side of the assembly ring 2. A recess 15 is provided in the lower part of the inner top ring 10. The recess 15 can allow the top rod 16 located at the lower part to move upward, so that there is enough space in the lower part to place the shield tunnel segments in the lower inner side of the assembly ring 2. A clamping member is fitted to the outer surface of the inner top ring 10. The pulling member is connected to the pneumatic extrusion member, the inner top ring 10 and the clamping member respectively. A conveying member is provided at the lower rear of the assembly ring 2.

[0027] The inner wall of the rubber ring 3 is provided with a ring array of multiple bearing grooves 29, the pneumatic extrusion component is located in the bearing groove 29, and the top claw 28 is located in front of the bearing groove 29.

[0028] The pneumatic extrusion component includes multiple guide sleeves 27 arranged in a ring array and embedded in the inner wall of the assembly ring 2. The guide sleeves 27 are located in the middle of the inner side of the bearing groove 29. A guide rod 26 is coaxially and tightly installed at the front of the guide sleeve 27. A plug 31 is tightly installed inside the guide sleeve 27. The plug 31 is fixedly connected to the rear of the guide rod 26. The guide rod 26 and the guide sleeve 27 serve to guide the air and, under the action of the plug 31, to push the gas into the jacking pipe 39. Two jacking pipes 39 are respectively provided on both sides of the guide sleeve 27. The jacking pipes 39 are fixed to the inner wall of the assembly ring 2. The front of the jacking pipe 39 is connected to the front of the guide sleeve 27. A top column 32 is slidably installed at the upper end of the jacking pipe 39. Each of the multiple bearing grooves 29 is provided with an extrusion seat 4. The bearing groove 29 serves to accommodate the extrusion seat 4. A rubber plate is provided on the extrusion seat 4 for the protection of the shield tunnel segments. The extrusion seat 4 is fixedly connected to the top column 32.

[0029] The clamping component includes a carrier ring 5 coaxially disposed on the outer side of the inner top ring 10. Multiple push rods 16 are elastically mounted in a ring array on the outer surface of the carrier ring 5. A top seat 19 is fixedly mounted on one end of the push rod 16 corresponding to the inner wall of the assembly ring 2. The carrier ring 5 serves to support the push rod 16. A rubber pad 20 is installed on one end of the top seat 19 corresponding to the inner wall of the assembly ring 2. The other end of the push rod 16 is semi-circular, which facilitates sliding against the surface of the inner top ring 10. The other end of the push rod 16 is attached to the outer surface of the inner top ring 10.

[0030] Both the front and rear ends of the push rod 16 have extension seats 17 extending from the other end. A return spring 18 is fixedly installed at the lower end of the extension seat 17. The extension seat 17 serves to support the return spring 18. The lower end of the return spring 18 is fixedly connected to the inner wall of the carrier ring 5. The return spring 18 pushes the push rod 16, making the push rod 16 press against the inner top ring 10. A gear ring 6 is coaxially fixedly installed on the rear end face of the carrier ring 5. Three motor frames 9 are fixedly installed in a ring array on the rear end face of the inner top ring 10. A servo motor 8 with a brake is fixedly installed at the end of the motor frame 9. The motor frame 9 serves to fix the servo motor 8 with a brake. The servo motor 8 with a brake can clamp the rotor after it stops rotating, preventing it from rotating. Since the servo motor 8 with a brake is widely used in life and is existing technology, it will not be described in detail here. A gear 7 is coaxially embedded at the output end of the servo motor 8 with a brake. The gear 7 meshes with the gear ring 6.

[0031] The pulling components include five No. 1 servo push cylinders 14 fixedly installed in a ring array on the inner wall of the tunnel boring machine shell 1. The No. 1 servo push cylinder 14 is located in front of the assembly ring 2. A connecting frame 13 is fixedly installed at the output end of the No. 1 servo push cylinder 14. A bearing ring 24 is fixedly installed at the front of the guide rod 26. The bearing ring 24 serves to connect multiple guide rods 26 together. The No. 1 servo push cylinder 14 serves to pull out the carrier ring 5 and the inner top ring 10, so that the assembled tunnel segments can be exposed for easy bolt tightening. On the other hand, it can push out the compression seat 4 to compress the tunnel segments from the outside, so that the multiple tunnel segments assembled into a ring can be tightly pressed together. The front end of the bearing ring 24 is coaxially rotatably connected to a second connecting ring 25. The front edge of the outer surface of the bearing ring 5 is rotatably connected to a first connecting ring 21. The front end face of the first connecting ring 21 is fixedly installed with a first fixing post 22. The front end face of the inner top ring 10 is fixedly installed with a second fixing post 23. The second connecting ring 25, the first fixing post 22, and the second fixing post 23 are all fixedly connected to the connecting frame 13. The outer surface of the bearing ring 5 near the first connecting ring 21 has multiple connecting frames 38 extending in a ring array. The ends of the multiple connecting frames 38 are all fixedly connected to the bearing ring 24. The connecting frames 38 serve to connect the bearing ring 5 and the assembly ring 2 together, so that they can rotate synchronously.

[0032] The conveying component includes a conveyor belt 11 located at the lower rear of the assembly ring 2. A support platform 12 is located in front of the conveyor belt 11. The support platform 12 supports the shield tunnel segments. The support platform 12 is located directly below the carrier ring 5. The upper end face of the support platform 12 is curved to accommodate the curved surface of the shield tunnel segments.

[0033] Two No. 2 servo push cylinders 33 are fixedly installed on both sides of the conveyor belt 11. Two No. 1 fixing ears 34 are fixedly installed at the output end of one of the No. 2 servo push cylinders 33. The end of the No. 1 fixing ear 34 is fixedly connected to the side of the support platform 12. The No. 1 fixing ear 34 serves to fix one of the No. 2 servo push cylinders 33 and the support platform 12 together. Two No. 2 fixing ears 35 are fixedly installed at the output end of the other No. 2 servo push cylinder 33. A No. 3 servo push cylinder 36 is fixedly installed at the upper end of the No. 2 fixing ear 35 located at the rear. The No. 3 servo push cylinder 36 serves to drive the No. 2 limit block 37 to move. The No. 2 limit block 37 is fixedly installed at the output end of the No. 3 servo push cylinder 36. A No. 1 limit block 30 is fixedly installed at the upper end of the No. 2 fixing ear 35 located at the front. The No. 2 limit block 37 and the No. 1 limit block 30 serve to limit the shield tunnel segment, so that the shield tunnel segment can fall vertically.

[0034] During assembly, the conveyor belt 11 transports the tunnel segment to the support platform 12. At this time, the bottom of the tunnel segment is attached to the arc-shaped surface of the support platform 12, and the first limiting block 30 is attached to the front end of the tunnel segment. Then, the two second servo push cylinders 33 work synchronously to push the support platform 12 out, so that the tunnel segment on the support platform 12 is directly below the carrier ring 5. Then, the third servo push cylinder 36 works to extend the second limiting block 37 to attach to the rear end of the tunnel segment. At this time, one of the second servo push cylinders 33 works to quickly pull back the support platform 12, so that the tunnel segment is at the first limiting block. Under the limiting of limit blocks 30 and 37, the assembly ring 2 falls vertically to the lower inner side of the assembly ring 2. Then, the servo motor 8 with the brake works, driving the carrier ring 5 and the assembly ring 2 to rotate synchronously and slowly through gear 7 and gear ring 6. The rotating assembly ring 2 causes the shield tunnel segment to move at a certain angle and then misaligns with the lower part of the assembly ring 2, after which the assembly ring 2 stops rotating. During the rotation of the assembly ring 2, the carrier ring 5 will rotate synchronously. At this time, the push rod 16, which was originally located in the recess 15 on the inner top ring 10, slides along the outer wall of the inner top ring 10 and is pushed out, so that the push rod 16... The top seat 19 can press against the shield tunnel segment to press the shield tunnel segment firmly against the assembly ring 2. The conveyor belt 11 repeats the above steps to place another shield tunnel segment on the lower inner side of the assembly ring 2. Then the assembly ring 2 continues to rotate, causing the shield tunnel segment to move at a certain angle and be misaligned with the lower part of the assembly ring 2. The assembly ring 2 then stops rotating. This cycle is repeated to assemble the shield tunnel segments into a ring shape. After the shield tunnel segments are assembled into a ring, the first servo pusher cylinder 14 will move to drive the connecting frame 13 forward. At this time, the forward-moving connecting frame 13 will synchronously drive the inner top ring 10 and the carrier ring. 5. Moving forward allows the top rod 16 on the carrier ring 5, which is pressed against the shield tunnel segment, to be pulled out, allowing multiple shield tunnel segments to converge under gravity. During the forward movement of the connecting frame 13, the guide rod 26 will also move forward. At this time, the plug 31 slides in the guide sleeve 27 to push the gas in the guide sleeve 27 into the jacking pipe 39, so that the top column 32 on the jacking pipe 39 is pushed out by the gas, thereby pushing out the extrusion seat 4 to extrude and extrude the shield tunnel segment from the outside, so that the multiple shield tunnel segments assembled into a ring can stick together tightly. Then, the bent bolts can be used to lock them.
