It is responsible for resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. When using the shield method to open up the tunnel, during the construction phase, the shield machine needs to be pushed into the obstacle first, and the shield shell and segments are used to support the surrounding rock to prevent collapse into the tunnel. At the same time, the soil is excavated by the cutting device in front of the shield machine. In order to strengthen the inner wall of the tunnel, most of the excavated soil is squeezed onto the inner wall around the tunnel. In addition, the concrete segment has a self-waterproof function. The current segment assembly generally adopts a single step-by-step installation, generally in accordance with the process of first down and then up, staggered left and right, longitudinally inserted, and capped into a ring.

[0053] Example 2

[0054] See also Figure 1 and Figure 2 A shield tunnel segment assembly device includes all the contents of embodiment 1, and further includes a supporting guide mechanism 8 and a supporting direction adjustment mechanism 7 arranged at the top of the second rail car 5, wherein the supporting guide mechanism 8 is arranged at one side of the mounting seat 2, and the supporting guide mechanism 8 includes a bottom bracket 81 fixedly connected to the outer wall of the mounting seat 2, a support plate 82 is fixedly connected to the lower end surface of the bottom bracket 81, and a plurality of support frames 83 are fixedly connected to the upper end surface of the bottom bracket 81, and a roller 84 cooperating with the ringway 121 is rotatably arranged on the upper side of each support frame 83. In the process of the first motor 11 rotating the transmission frame 12, the ringway 121 can be stably rotated under the support of the roller 84.

[0055] The assembly mechanism 1 and the mounting seat 2 can be supported and turned by the support and direction adjustment mechanism 7. The support and direction adjustment mechanism 7 includes a support gear plate 73 rotatably connected to the top of the second rail vehicle 5, the support gear plate 73 is fixedly connected to the support plate 82, the top of the second rail vehicle 5 is fixedly connected to a frame 72, the outer wall of the frame 72 is fixedly connected to a third motor 71 by bolts, and the output shaft end of the third motor 71 is fixedly connected to a driving gear 74 meshing with the support gear plate 73.

[0056] In this embodiment, when using Fig. 9 When assembling in the (mounting seat 2 is not assembled with the shield machine 9) manner, after the two expansion and contraction mechanisms 13 have completed hanging the pipe segment body 3, start the third motor 71, the third motor 71 rotates the driving gear 74, the driving gear 74 rotates the supporting gear plate 73 clockwise, and the supporting gear plate 73 drives the mounting seat 2 to rotate 180°, thereby rotating the assembling mechanism 1 180°, and then the assembling mechanism 1 is transported to the tunnel formed by the shield machine 9 through the second rail car 5.

[0057] Working principle and use process: When the assembly device of the present invention is used to assemble the shield tunnel segments, the segment body 3 to be assembled is placed on the first rail car 4 through an external lifting device, and the segment body 3 to be assembled is moved to the assembly mechanism 1 through the first rail car 4. After that, the first motor 11 is started by the external control device, and the first motor 11 rotates the transmission frame 12, and one of the suspension parts 135 is placed above the segment body 3 to be assembled. During the rotation of the transmission frame 12, the ring track 121 can rotate stably under the support of the roller 84. It should be noted that the suspension part 135 can adopt a grabbing mechanism in the prior art. For example, the suspension part 135 can be an arc plate that matches the segment body 3. The arc plate and the segment body 3 are detachably fixed by bolt connection. The suspension part 135 can also be an electric suction cup that can fix the segment body 3 by adsorption. It is an existing mature technology and will not be described in detail here.

[0058] When the slab body 3 placed on the first rail car 4 is hoisted, the second motor 14 is started, and the second motor 14 drives the transmission gear 161 to rotate through its output shaft, and the transmission gear 161 drives the driven gear 164 to rotate, and the driven gear 164 drives the rotating sleeve 133 to rotate, and the rotating sleeve 133 drives the gear ring 132 to rotate. During the rotation of the gear ring 132, under the guidance of the arc groove 136, the right-angle frame 134 is pushed by the lever 137, so that the right-angle frame 134 extends outward, driving the suspension member 135 to expand outward, until the suspension member 135 located on the lower side contacts the slab body 3 placed on the first rail car 4, completing the connection between a pair of slab bodies 3 and the first rail car 4.

[0059] After that, the second motor 14 is reversed to retract the suspension piece 135 that has expanded to the periphery, and then the transmission frame 12 is rotated by the first motor 11, and the transmission frame 12 drives the expansion and contraction mechanism 13 to rotate one station, so that the next tube sheet body 3 that has not been connected is rotated to the bottom, and the next round of tube sheet body 3 and the first rail car 4 are connected. After several suspension pieces 135 on one expansion and contraction mechanism 13 are connected to the tube sheet body 3, the suspension pieces 135 on another expansion and contraction mechanism 13 are connected to the tube sheet body 3 in the same way.

[0060] When using Fig. 9 When the mounting base 2 is assembled with the shield machine 9, the third motor 71 is started, the third motor 71 rotates the driving gear 74, the driving gear 74 rotates the supporting gear plate 73 clockwise, and the supporting gear plate 73 drives the mounting base 2 to rotate 180°, so that the assembly mechanism 1 rotates 180°, and then the second rail car 5 transports the assembly mechanism 1 to the tunnel formed by the shield machine 9. Fig.10When assembling in the (assembly of mounting base 2 and shield machine 9) manner, during the forward movement of shield machine 9, assembling mechanism 1 moves forward along with shield machine 9, and segments of the inner wall of the tunnel are assembled by assembling mechanism 1.

[0061] Specifically, before assembly, several suspension parts 135 on the two expansion and contraction mechanisms 13 are put into the tunnel opened by the shield machine 9 in a retracted and close state. During assembly, several suspension parts 135 on the two expansion and contraction mechanisms 13 are expanded and unfolded. Initially, the pipe segment bodies 3 on the two expansion and contraction mechanisms 13 are staggered along the length direction of the tunnel. After several suspension parts 135 are unfolded, the suspension parts 135 are in contact with the inner wall of the tunnel. At this time, the electric hydraulic device 15 is started, and the electric hydraulic device 15 contracts the hydraulic rod, which drives the telescopic prism 162 to slide inside the prism frame 163, so that the telescopic prism 162 approaches the mounting seat 2, so that the two expansion and contraction mechanisms 13 are close to each other, and several pipe segment bodies 3 on the two expansion and contraction mechanisms 13 can be spliced ​​to form a circular ring shape to support the inner wall of the tunnel. The two adjacent tube-piece bodies 3 are connected by sliding fit. In order to improve the connection strength between the two adjacent tube-piece bodies 3, the ends of the two adjacent expansion and contraction mechanisms 13 that are close to each other can be fixed with a plug-in shaft 31 and a plug-in cavity 32 for the plug-in shaft 31 to be plugged in, respectively, so that when the two adjacent tube-piece bodies 3 are assembled, the plug-in shaft 31 can automatically slide into the plug-in cavity 32, thereby improving the connection stability between the two adjacent tube-piece bodies 3.

[0062] It is worth noting that the circuits, electronic components and modules involved in the present invention are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
