[0002] Shield segment assembly is a critical step in tunnel construction, crucial for safety and duration. The most common segment assembly process in China currently uses bolts. This involves the shield machine first stopping tunneling, transporting the segments to designated locations, and then manually bolting them together to secure the joints.

DETAILED DESCRIPTION

[0017] The above and other technical contents, features and effects of the present invention are described below with reference to the attached Figures 1 to 8 It can be clearly presented in the detailed description of the embodiments that the structural contents mentioned in the following embodiments are all referenced to the drawings in the specification.

[0018] This embodiment provides a shield segment connection structure, as shown in the attached Figure 1-8 As shown in the instruction manual, Figure 1 This is the three-dimensional structure diagram of this scheme, and the instruction manual is attached. Figure 2 Cut along the top of the rotating ring 2 to show the shape of the rotating ring 2. Figure 4 This is a schematic diagram of the docking of the two sides of the rotating ring 2, and the instruction manual is attached. Figure 5 The upper side structure of the rotating ring 2 is cut off to facilitate observation of the upper structure of the rotating ring 2. Figure 6 The pipe segment 1 is hidden, and the instruction manual is attached. Figure 7 The extrusion valve 19 and one side of the docking rod 9 are cut, and the manual intentionally cuts one side of the pipe segment 1. The design core of this solution is the rotating ring 2. The rotating ring 2 is a piece with an annular angle, which is sixty degrees in the solution. The pipe segment 1 is also sixty degrees, so six pipe segments 1 are needed to form an annular circle, which means that the left side of the rotating ring 2 needs to be docked with the right side of the rotating ring 2 to form an annular docking. This is the horizontal docking of this solution. This solution also has a vertical docking. The vertical docking of this solution is the docking rod 9 and the pressing rod 10. The left side of the rotating ring 2 is a docking structure, and the right side of the rotating ring 2 is a fastening structure. The rotating ring 2 of this solution can rotate, and the rotation of the rotating ring 2 depends on the pressing rod 10. A bevel block 11 is provided on one side of the pressing rod 10. The rotating block 12 can rotate and move during the downward movement of this bevel block 11, as shown in the attached manual. Figure 6 As shown, the rotating block 12 is rotatably arranged on the rotating ring 2, and an anti-slip structure is provided between the two, so that the rotating block 12 can rotate above the rotating ring 2. When the pressing rod 10 moves downward, the rotating block 12 can drive the rotating ring 2 to rotate clockwise. Because a corresponding chamfer 14 is provided on one side of the rotating block 12, corresponding to the shape of the inclined block 11, the inclined block 11 moves downward to push the rotating ring 2 and the rotating block 12 to rotate together. After the pipe segments 1 of this scheme are annularly butted, the rotating ring 2 rotates, which makes the rotating ring 2 rotate inside the annular tunnel, achieving The effect of rotational dislocation is achieved, so that one side of a rotating ring 2 on a separate pipe segment 1 is inserted into the pipe segment 1 next to it, and when the rotating ring 2 rotates, the rotating ring 2 can form a complete ring, so that the complete ring connects the scattered pipe segments 1, making the whole group of pipe segments 1 stable. Under the premise of the rotation of the rotating ring 2, the two side structures of the rotating ring 2 are set, and a rectangular interface is provided on both sides of the rotating ring 2. The structures on both sides of the rectangular interface are connected to each other. In order to facilitate the understanding of this solution, a separate pipe segment 1 is connected to the next pipe segment 1 on the other side, as shown in the attached manual. Figure 2As shown, there is a dotted line on the left side, which cuts the whole, and the structure on the curved side appears on the side of the label A, so that a docking is formed for easy understanding. Figure 5 and 6 The same meaning is also provided in the instruction manual. Figure 3 As shown, at this time, the rotating ring 2 rotates clockwise, which will cause the torsion block 6 to rotate. There is a long rod above the torsion block 6, which is overlapped on the guide groove 15, and the guide groove 15 is provided on the pipe segment 1. Therefore, the rotation of the rotating ring 2 can cause the torsion block 6 to rotate counterclockwise. During the rotation of the torsion block 6, it can also overlap on the positioning block 5, because a slidable slider 7 is provided on one side of the torsion block 6, and a round rod is provided on one side of the slider 7. One side of the round rod is an inclined surface, which can extend to the left side of the positioning block 5, thus forming a complete inclined surface with the positioning block 5. When the torsion block 6 rotates, the round rod can slide along the complete inclined surface. Since there is a sliding distance between the torsion block 6 and the slider 7, the slider 7 can enter the attached manual. Figure 3At the position of the label 5, a snap connection is formed. Here, it is necessary to introduce a structure that does not appear in this solution, that is, a structure that forms a complete inclined surface with the positioning block 5. This structure is on one side of the round block of the slider 7, just overlapping the inclined surface, and this inclined surface is integrally provided on one side of the rotating ring 2 and on both sides of the slider 7, so that the slider 7 can overlap the positioning block 5. Due to the setting of the sliding distance between the torsion block 6 and the slider 7, the slider 7 reaches the maximum distance when it reaches the middle of one side of the positioning block 5, so that the slider 7 overlaps the positioning block 5, and The structure of the slider 7 and the torsion block 6 is on the other side of the rotating ring 2, so that one side of the rotating ring 2 is overlapped on the next rotating ring 2 to form a complete closed loop, and an insertion block 8 is slidably provided on one side of the torsion block 6. Corresponding circular holes are provided on the upper and lower sides of the insertion block 8. A corresponding rod is provided on the side of the number 8. This rod ensures that the insertion block 8 slides toward the insertion groove 3, and one side of the insertion block 8 extends to the bottom of the torsion block 6. When the torsion block 6 rotates, it can be inserted into the insertion groove 3 against the insertion block 8, and one side of the insertion block 8 is a The insertion groove 3 just corresponds to the end of the square, and the two will form a seal when inserted. In order to make the insertion block 8 easy to insert, this solution is provided with an exhaust port 4 on one side. Since the ultimate goal of this solution is to block the exhaust port 4, a seal is formed between the square end of the insertion block 8 and the inside of the insertion groove 3. In this way, a vacuum is formed on one side, which is difficult to pull out. The blocking of the exhaust port 4 depends on glue. The glue will be introduced in the next paragraph. The glue will reach one side of the rotating ring 2. When the insertion block 8 is inserted, due to the insertion block 8 The middle shape is an elliptical setting that can be squeezed and expanded, so the insertion process can become an ellipse with a large minor axis, corresponding to the rotation of the insertion slot 3. Because the present scheme is configured and glue is poured, the glue will fill the ellipse after entering, and form an anti-slip structure with the ellipse, which is difficult to pull out, making it difficult for one side of the rotating ring 2 to be pulled out to the next rotating ring 2. Under the setting of two-way fixation, the assembly and rotation of the rotating ring 2 are realized to form a complete ring, and an anti-slip groove 24 is also provided on one side of the rotating ring 2. The anti-slip groove 24 is shaped with a wider side and a narrower middle, as shown in the attached instruction manual. Figure 6 As shown, an anti-slip block 17 is slidably provided inside the pipe segment 1. This anti-slip block 17 is limitedly slidably provided inside the pipe segment 1, and is not suspended as shown in the accompanying drawings. A spring is provided above the anti-slip block 17, and this spring is in an extruded state in the figure. Therefore, once the rotating ring 2 rotates, the anti-slip groove 24 corresponds to the anti-slip block 17. In this way, under the action of the spring, the anti-slip block 17 will be inserted into the rebound groove, so that the pipe segment 1 can fix the interfaces of the rotating rings 2 on both sides, forming an overall fixed effect. It is only necessary to open a reserved sliding space on the pipe segment 1 to facilitate the anti-slip block 17 to slide downward.

[0019] This section introduces the structure that can be driven by the rotation of the control rotating ring 2. First, the rotating block 12 can be rotated and reset. Since the rotating block 12 can drive the rotating block 12 to rotate when the pressing rod 10 is pressed downward, in order to make the rotating ring 2 of this scheme able to fix the position of the pressing rod 10, a notch is provided on the edge of the pressing rod 10 to facilitate the rotation of the rotating ring 2. After the rotating ring 2 is rotated to a certain angle, the left side of the notch will reach the left side of the pressing rod 10, as shown in the attached manual. Figure 6 As shown, at this time, only the right side of the pressing rod 10 needs to be fixed to achieve the fixation of the pressing rod 10. In order to make the right side of the pressing rod 10 fixed, this solution sets a resettable rotating block 12, and a squeezing rod 16 is rotatably set on one side of the rotating block 12. The squeezing rod 16 is a telescopic rod, so there is a No. 1 rod and a No. 2 rod. The No. 1 rod is rotatably set on one side of the rotating block 12, and one end of the No. 2 rod is sealed and slid with the No. 1 pipe. The other end of the No. 2 rod is rotatably set on the pipe segment 1. Since the interior between the two is hollow, there is a storage The space is not able to discharge gas, so when the No. 1 and No. 2 rods are squeezed, the air inside is compressed. In the process of the pressing rod 10 and the inclined block 11 moving downward, the inclined block 11 will eventually reach the bottom of the rotating block 12, so that the rotating block 12 has a reset space. The rotating block 12 is reset under the driving force of the internal pressure of the squeezing rod 16 (a spring connecting the No. 1 and No. 2 rods can also be set inside the squeezing rod 16 to make the spring team reset the squeezing rod 16), that is, it returns to the state attached to the instruction manual. Figure 5 The state of this makes the pressing rod 10 clamped between the rotating block 12 and the notch of the rotating ring 2, achieving the effect of fixing the pressing rod 10 left and right, and the pressing rod 10 cannot be reset upward at this time. A one-way groove is provided on the side of the pipe segment 1. The annular angle formed by the one-way groove is smaller than the rotation angle of the rotating ring 2, and a guide bar 27 is provided on one side of the pipe segment 1. The angle of the guide bar 27 is between the rotation angle of the one-way groove and the rotating ring 2. Due to the action of the guide bar 27, the one-way block 13 is squeezed during the rotation of the rotating block 12. A spring is provided on one side of the one-way block 13. This spring is compressed. Therefore, once the rotating block 12 rotates to a certain position, the one-way block 13 will be released. Figure 5 As shown, the guide bar 27 is an annular bar, most of which is blocked by the rotating block 12. Figure 5The annular shape extends all the way to the tail of the one-way groove, so that the final angle of rotation of the rotating block 12 will reach the edge of the one-way groove, that is, the right side in the figure, and after reaching the right side, it will break away from the top movement of the guide bar 27. At this time, the one-way bar will reach the right side of the one-way groove under the reset of the spring and contact the inner wall of the pipe segment 1. After the extrusion rod 16 is reset, it pushes the rotating block 12 to reset. At this time, the one-way block 13 and the one-way groove form a one-way movement. As the rotating block 12 is reset, the one-way block 13 is in the one-way groove. The pressing rod 10 can only be moved in the direction of the pressing rod 10 and cannot be rotated in the direction of the pressing rod 10, so as to achieve the effect of fixing the pressing rod 10. The pressing rod 10 is pressed downward (multiple segments 1 are required to form a ring and then press multiple groups of pressing rods 10 together) to be connected to the docking rod 9. The docking rod 9 is provided with docking blocks 22 on both sides. Since the docking blocks 22 are provided up and down, and the docking rod 9 of this scheme is fixedly provided inside the segment 1, and the docking rod 9 needs to dock the pressing rod 10 up and down, it is attached to the manual. Figure 6 The dotted line also represents how the bottom of the docking rod 9 is connected to the pressing rod 10, so that the pressing rod 10 is automatically inserted into the docking rod 9 when pressed downward, and the docking rod 9 is successfully docked on the docking rod 9 from the bottom when pressed downward, forming a buckle fixation. In order to prevent the rotating ring 2 from resetting, this solution is provided with a lifting column 26. The lifting column 26 is vertically slidably arranged inside the pipe segment 1, and a spring is provided on the top for resetting. A clamping block 25 is provided above the rotating ring 2. The clamping block 25 can rotate to move upward against the lifting column 26 and then reset downward, preventing the rotating ring 2 from resetting. Finally, the extrusion valve 19 of this solution is introduced. The extrusion valve 19 of this solution is fixedly arranged on the pipe segment 1. In order to facilitate the display of this solution, the specification is attached.
