[0002] Shield tunnels require the use of prefabricated tunnel lining construction, and require the construction of segments in a bricolage (assembly) for the tunnel.

[Figure 4] FIG. 2 is a top schematic view of a transmission structure according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The shield segment joint transportation system replaces the segment transportation by the first crane 1 and the second crane 2 with the transmission structure 3 during the segment transportation process, thereby avoiding the occurrence of the phenomenon of segments falling during the transportation process of the first crane 1 and the second crane 2, and the moving speed of the transmission structure 3 is higher than that of the first crane 1 and the second crane 2, enabling rapid transportation of segments at the construction site. The segment joint transportation system makes it possible to calculate the most effective method of mutual cooperation between the first crane 1, the second crane 2 and the transmission structure 3, thereby improving the transportation efficiency of the segments at the site of use.

[0016] Here, the transmission structure 3 can transport two sets of segments at the same time, and during the operation of the transmission structure 3, the shield segment joint transportation system completes the transportation trajectory planning of the transmission structure 3 in advance, and the transmission structure 3 cooperates with the first crane 1 and the second crane 2 to plan the transportation of the segments. Since the first crane 1 and the second crane 2 can only transport one set of segments, during the transportation process of the segments, the shield segment joint transportation system calculates the optimal running positions of the first crane 1, the second crane 2 and the transmission structure 3, so that the transportation efficiency of the segments can be accelerated.

[0017] An embodiment of the present invention provides a shield segment joint transportation system, which calculates the distance from point M1 to point E, the distance from point M2 to point E, and the distance from point M3 to point E, as shown in FIGS.

[0018] S11, obtain the segment conveying distance as L, define the conveying speed of the first crane 1 and the second crane 2 as V0, the transmission speed of the transmission structure 3 as V1, the starting point of the transportation process as E, and the end point of the transportation process as F.

[0019] S12, calculate L based on equation (1); Segment travel of group A: V1t1+V0(t2+t3)=L; Segment travel of group B: V0(t1+t2)+V1t3=L; Segment travel for group C: V1(t1+t2+t2)=L+2((V1-V0)t1-V0t2) (1) S12, calculate t based on equation (2); JPEG2025054151000004.jpg29170t1, t2 and t3 are the three times for transmitting the segments A, B and C, respectively, and the cumulative time is the total time length for transporting the three segments.

[0020] Then, the specific positions of M1, M2 and M3 at the construction site are calculated based on the above formulas (1) and (2), S13, calculate M1, M2 and M3 based on equation (3); JPEG2025054151000005.jpg37170It should be explained that the shield segment joint transportation system derives equation (2) from equation (1) based on the input of measured data parameters, and further calculates from equation (1) and equation (2), which is a very important step of measurement, including: the segment transporting distance is L, the transporting speed of the first crane 1 and the second crane 2 is V0, and the transmission structure 3 transmission speed is V1, where it further includes the time of loading the segment from the first crane 1 to the transmission structure 3, the time of loading the segment from the second crane 2 to the transmission structure 3, the time of unloading the segment from the first crane 1, and the time of unloading the segment from the second crane 2, thereby ensuring that the connection points between the first crane 1, the second crane 2 and the transmission structure 3 are more accurate.

[0021] The shield segment joint transportation system according to an embodiment of the present invention includes a first crane 1, a second crane 2, a transmission structure 3, and a segment, the first crane 1 and the second crane 2 are installed on both sides of the transmission structure 3, the first crane 1, the second crane 2 and the transmission structure 3 are all used to transport the segment, the segment includes a group A, a group B and a group C, where L is defined as the segment transport distance, V0 is defined as the transport speed of the first crane and the second crane, V1 is the transmission speed of the transmission structure, E is the start point of the transportation process, F is the end point of the transportation process, M1, M2, M3 are three points defined during the transmission, t1, t2 and t3 are three times divided when all the segments are transported from point E to point F, where the distance formula from point M to point E is calculated based on the process formula L=Vt, where the distance formula from point M to point E is calculated based on the process formula L=Vt, where the distance formula from point M to point E is calculated based on the process formula L=Vt, where the distance formula from point A to point E is calculated based on the process formula L=Vt, where the distance formula from point A to point E is calculated based on the process formula L=Vt, Segment travel: V1t1+V0(t2+t3)=L, segment travel of group B: V0(t1+t2)+V1t3=L, segment travel of group C: V1(t1+t2+t2)=L+2((V1-V0)t1-V0t2), and calculate the transportation travel of the segment based on the travel formula L=Vt, where segment travel of group A: V1t1+V0(t2+t3)=L, segment travel of group B: V0(t1+t2)+V1t3=L, segment travel of group C: V1(t 1+t2+t2)=L+2((V1-V0)t1-V0t2), and further includes a transmission structure 3, which includes a guide rail 31 and a rope hoisting device 33, a transport frame 32 is slidably connected to the surface of the guide rail 31, a wire rope 34 is wound around and connected to the surface of the rope hoisting device 33, a fixed wheel 35 is fixedly connected to the surface of the guide rail 31, and a movable wheel 36 is fixedly connected to the surface of the transport frame 32.

[0022] Optionally, the rope winding device 33 is driven by a motor, there are two sets of the rope winding device 33, and the rope winding device 33 is diagonally distributed on both sides of the guide rail 31, and the two sets of the rope winding device 33 are indirectly actuated.

[0023] Here, after the rope hoisting device 33 is started, it can pull the transport frame 32 to slide on the guide rail 31. During the sliding process, the transport frame 32 slides to the side that starts the rope hoisting device 33, so that the transport frame 32 pulls the two sets of segments to move around the construction site, where the first crane 1, the second crane 2 and the transmission structure 3 cross-operate to avoid mutual interference between the first crane 1, the second crane 2 and the transmission structure 3.

[0024] Alternatively, the wire rope 34 is installed on both sides of the guide rail 31, and the rope winding device 33 continuously winds the wire rope 34 on both sides of the wire rope 34 on the surface of the rope winding device 33 after starting.

[0025] Here, the wire rope 34 slides on the fixed wheel 35 and the movable wheel 36, and when the rope winding device 33 is operating on one side of the wire rope 34, the fixed wheel 35 and the movable wheel 36 move closer to each other, and when the rope winding device 33 is not operating on one side of the wire rope 34, the fixed wheel 35 and the movable wheel 36 move away from each other.

[0026] Alternatively, the wire rope 34 slides on the surface of the fixed wheel 35, and the wire rope 34 is guided by the fixed wheel 35 during the winding process, and the movable wheel 36 pulls the transport frame 32 via the wire rope 34 and slides on the surface of the guide rail 31.

[0027] Here, the transport frame 32 always moves on the guide rail 31 carrying two sets of segments, and the moving direction of the transport frame 32 continues to indirectly activate the rope winding device 33 according to the transporting direction of the segments, and the activation of different rope winding devices 33 realizes the reciprocating operation of the transport frame 32 on the guide rail 31, so that the transmission structure 3 quickly delivers the segments between the first crane 1 and the second crane 2, thereby achieving the effect of improving efficiency.

[0028] A shield segment joint transportation implementation method, comprising the steps of: S1: The transmission structure 3 transports the A and C groups, and the first crane 1 transports the B group segments and departs. After the time t1 has elapsed, the A and C group segments arrive at the M3 point, and the B group segment arrives at the M1 point. S2: The A group segments are lifted from the transmission mechanism to the second crane 2, the second crane 2 continues to transport the A group segments forward, the first crane 1 continues to transport the B group segments forward to the end point F, and the transmission structure 3 carries the C group segments back along the original path to point E, and after a time t2, it intersects with the B group segments at point M2; S3: The first crane 1 lowers the segments of group B into the transmission mechanism, and the transmission structure 3 carries the segments of groups B and C, and arrives at point F at the same time as the segments of group A carried by the second crane 2, after a time t3 has elapsed.

[0029] To summarize the above, after adding the variable of transmission structure 3, the shield segment joint transportation system transports three sets of segments each time, namely set A of segments, set B of segments and set C of segments, and by calculating the speed of the first crane 1, the second crane 2 and the transmission structure 3, and calculating the segment transportation distance, the optimal turning points M1, M2 and M3 between points E and F of the first crane 1, the second crane 2 and the transmission structure 3 are calculated. As shown in Figures 1, 2 and 3, the shield segment joint transportation construction method is simultaneously adjusted to the optimal driving route calculated by the shield segment joint transportation system, thereby improving the segment transportation efficiency at the transportation site.

[0030] Working principle: First, measure the conveying speed V0 of the first crane 1 and the second crane 2, the transmission speed V1 of the transmission structure 3, and the starting point positions E and F. At this time, derive the segment travel formula (2) from formula (1). Then, calculate the specific positions from M1, M2, and M3 to point E from formula (1) and formula (2). Thus, the travel distance of the first crane 1, the second crane 2, and the transmission structure 3 can be accurately controlled. After sending the control data to the first crane 1, the second crane 2, and the transmission structure 3, the transportation of the segments is started. The first crane 1 leaves the segments of group A and group C on the transmission structure 3 at point E. The first crane 1 carries the segments of group B and departs together with the transmission structure 3. At this time, after the time t1 has elapsed, the segments of group A and group C are transported. When the first crane 1 arrives at point M3, the group B segments arrive at M1, and the group A segments are lifted from the transmission structure 3 to the second crane 2, the second crane 2 continues to transport the group A segments forward, and the first crane 1 continues to transport the group B segments forward to the end point F, while the transmission mechanism carries the group C segments back to point E along the original path, and after a time t2, intersects with the group B segments at point M2, the first crane unloads the group B segments onto the transmission mechanism, and the transmission mechanism carries the groups B and C segments and arrives at point F simultaneously with the group A segments carried by the second crane after a time t3, and at this time the task of transporting the groups A, B, and C segments from point E to point F can be completed.
