[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, and provides a pipe ring construction method, which includes step 1, moving the assembly platform 201 to the vicinity of the pipe segment 300, and placing the pipe segment 300 above the assembly platform 201;

[0032] Among them, placing the pipe segment 300 on the assembly platform is conducive to the subsequent transportation of the pipe segment. On the assembly platform 201, the staff can inspect the pipe segment 300 to confirm that the pipe segment 300 is of the correct type, the quality is intact, and the sealing gasket is bonded without falling off, so as to avoid the damaged pipe segment 300 from being assembled, causing subsequent problems with the entire pipe ring.

[0033] Placing it on the assembly platform 201 also makes it convenient for the staff to clean the pipe segment 300, ensuring that the pipe segment 300 to be spliced ​​is neat, especially that the water stop strip of the pipe segment 300 must not be stuck with mud and sand. The presence of mud and sand may cause the water stop strip to be damaged and leak water. At the same time, the sand particles will cause stress concentration, causing the pipe segment 300 to crack under stress.

[0034] Step 2: Adjust the direction of the pipe segment 300 to ensure that the pipe segment 300 on the assembly platform 201 can be assembled smoothly;

[0035] The position of the pipe segments 300 placed on the assembly platform 201 and the order of placement of the required assembled pipe segments 300 are confirmed to ensure accuracy, ensure accurate positioning during splicing, and control its flatness to prevent the connection between the two pipe segments 300 from being staggered, which affects the assembly quality.

[0036] Furthermore, the direction of the pipe segment 300 is adjusted, the first protrusion 301 of the pipe segment 300 placed on the assembly platform 201 is aligned with the first recess 302 , and the first protrusion 301 is inserted into the first recess 302 .

[0037] Furthermore, the first protrusion 301 is located on one side of the tube sheet 300 , and the first recess 302 is located on the side of the tube sheet 300 corresponding to the first protrusion 301 .

[0038] During assembly, mechanical equipment is used for lifting, such as a hand hoist, a manipulator, etc., and the position is corrected manually to ensure that when the pipe segments 300 are butt-jointed, the first protrusion 301 of one pipe segment 300 is aligned with the first recess 302 of the other pipe segment 300, and the first protrusion 301 is inserted into the first recess 302, and it is ensured that there is no large gap between the two after insertion, so as to ensure the flatness after connection.

[0039] In addition, by installing the pipe segments 300 on the assembly platform 201, the docking conditions between the pipe segments 300 can be checked in real time to ensure that when they are spliced ​​into a pipe ring, each connection can meet the installation standards. If an error occurs during installation, it can be adjusted in time, which reduces the time for adjusting the pipe segments 300 after installation errors of conventional pipe segments 300, and can greatly ensure the excavation efficiency of the shield machine.

[0040] Step 3: fix the joints of the spliced ​​segments 300 and move the spliced ​​segments 300 to the center of the assembly platform 201;

[0041] After the pipe segments 300 are assembled, since the pipe segments 300 are located on the assembly platform 201 , it is convenient for the staff to fix the connection of the pipe segments 300 to ensure the firmness and stability of the connection and prevent leakage at the connection of the pipe segments 300 .

[0042] Effectively fixing the pipe segment 300 ensures the durability of the pipe segment, and can indeed increase its bearing capacity and earthquake resistance, and can also prevent the connection of the pipe segment 300 from loosening when the pipe segment 300 is installed in the shaft.

[0043] Step 4: transport the assembled pipe segments 300 to a designated location beside the shaft via 201 .

[0044] The assembled pipe segments 300 are transported to the side of the shaft by the assembly platform 201, so that the assembled pipe rings can be conveniently spliced ​​with the pipe rings installed in the shaft by the mechanical clamps at the side of the shaft. The pipe segments 300 can be spliced ​​at a distance, which can save space next to the shaft and make corresponding preparations for installing the required equipment.

[0045] By transporting the pipe segments 300 after assembling them on the splicing platform 201 , there is no need to move a large number of un-spliced ​​pipe segments 300 , thereby reducing the possibility of damage to the pipe segments 300 during transportation and ensuring the quality of the pipe segments 300 .

[0046] Furthermore, the pipe segment 300 is transported to a designated position next to the shaft, and the pipe segment 300 on the assembly platform 201 is moved into the shaft by a robot next to the shaft, the second recess 304 on the pipe segment 300 is placed on the second protrusion 303 of the pipe segment 300 in the shaft, and the connection is fixed.

[0047] Furthermore, the second protrusion 303 is located on a side of the tube sheet 300 different from the first recess 302 and the first protrusion 301 , and the second recess 304 is located on a side of the tube sheet 300 corresponding to the second protrusion 303 .

[0048] During installation, it is necessary to ensure that the pipe ring to be installed is offset from the joint of the installed pipe ring to ensure a stable connection. The second recess 304 on the pipe segment 300 is placed on the second protrusion 303 of the pipe segment 300 in the shaft. Through the cooperation between the second recess 304 and the second protrusion 303, it is ensured that it remains on the same axis as the pipe segment 300 in the shaft.

[0049] After installation, the connection between the second recess 304 and the second protrusion 303 needs to be fixed to ensure the stability of the connection between the two.

[0050] Example 2

[0051] Reference Figure 1 to Figure 4 , which is the third embodiment of the present invention, and is based on the previous embodiment. This embodiment provides a transportation device, which includes a transportation component 100, the transportation component 100 includes a sleeper 102 and a track 101 symmetrically fixed on the sleeper 102; a bearing component 200, the bearing component 200 includes an assembly platform 201 and a motor 202 arranged under the assembly platform 201; wherein the bearing component 200 is used to transport the pipe segment 300, and the transportation component 100 is used to ensure the moving trajectory of the bearing component 200.

[0052] The transport component 100 and the bearing component 200 can be used to transport the pipe segment 300 , and the motor 202 can provide power for the movement of the assembly platform 201 , so that the assembly platform 201 can move smoothly.

[0053] Specifically, two groups of connecting blocks 201a are symmetrically arranged at the bottom of the assembly platform 201, each group of connecting blocks 201a is rotatably connected to a rotating shaft 201b, both ends of the rotating shaft 201b are fixedly connected to rollers 201c, and the outer ring of the rotating shaft 201b is fixedly sleeved with a first bevel gear 201e.

[0054] Furthermore, an annular groove 201d is formed at the center of the roller 201c, and the annular groove 201d matches with the raised portion of the track 101.

[0055] Furthermore, the motor 202 is installed at the bottom center of the assembly platform 201 through the mounting plate 202b, and the output end of the motor 202 is fixedly connected to the second bevel gear 202a through the roller 201c, and the first bevel gear 201e is meshed with the second bevel gear 202a.

[0056] The connecting block 201a can provide conditions for the installation of the rotating shaft 201b, and the connecting block 201a is supported by the roller 201c. The first bevel gear 201e is configured to engage with the second bevel gear 202a. The connecting rod 202c is driven to rotate by the motor 202, thereby driving the second bevel gear 202a to rotate. When the second bevel gear 202a rotates, it can also drive the first bevel gear 201e to rotate, thereby driving the roller 201c to move on the track 101 to realize the transportation of the pipe segment 300.

[0057] The provision of the annular groove 201d can achieve a close fit with the track 101, limit the position of the roller 201c and the track 101, and prevent derailment during movement.

[0058] Example 3

[0059] Reference Figure 1 to Figure 4, which is the third embodiment of the present invention, this embodiment is based on the second embodiment, and this embodiment also includes two transport components 100 that are symmetrically bent, each transport component 100 is provided with a load-bearing component 200, and part of the pipe segments 300 are placed above the assembly platform 201 in the load-bearing component 200, and the pipe segments 300 can be spliced ​​into a ring shape.

[0060] The track 101 is arranged in an arc shape and is laid in cooperation with the sleepers 102 , so as to change the running track of the bearing assembly 200 , and at the same time avoid the components required by the installed shield machine.

[0061] During use, different numbers of pipe segments 300 can be assembled on the two supporting components 200 respectively. Then, when the two supporting components 200 converge, the spliced ​​partial circular rings on the two assembling platforms 201 are combined into a circular ring through the pushing mechanism arranged above the assembling platform 201. Then, the two motors 202 are controlled to rotate at the same speed, so that the two assembling platforms 201 move at the same speed. When the assembling platform 201 moves to the specified position, the motor 202 is stopped, and then the assembled pipe segments 300 are installed by mechanical equipment.

[0062] A vertical track 101 leading to the mechanical equipment can also be used. The end of the vertical track 101 is divided into multiple tracks 101. A bearing assembly 200 is set on each track 101. The pipe segments 300 can be spliced ​​at multiple locations. By controlling the time when different assembly platforms 201 arrive at the vertical track 101, the pipe segments 300 can be quickly installed in the shaft.

[0063] Meanwhile, a plurality of tracks 101 may be provided to reach the mechanical device attachments from different positions, and transport the pipe segments 300 spliced ​​into a ring over different bearing assemblies 200. The rotation speed of the motor 202 is controlled so that the two bearing assemblies 200 reach the vicinity of the mechanical device at different or the same speeds, and the spliced ​​pipe segments 300 are placed in the shaft by the mechanical device.

[0064] This solution can not only meet the needs of shield machines with different excavation speeds, but also avoid a large number of installed equipment, while achieving good transportation efficiency.
