Subway shield segments need to be transported in the tunnel for installation at the front end of the tunnel.

[0003] Subway shield segments need to be transported in the tunnel by a transport rack. In the existing transport rack, the upper subway shield segments are at a relatively high position after the subway shield segments are stacked. Due to the limited space in the tunnel, it is not convenient to hoist and remove the stacked subway shield segments, which is not convenient for the subsequent installation of subway shield segments. It is difficult for the transport rack to transport subway shield segments in batches.

[0004] Therefore, a subway shield segment transport rack is proposed. Content of the Utility Model

[0023] An embodiment of the present utility model provides a subway shield segment transport rack, as Figures 1-4As shown in the figure, it includes a support platform 1. The top of the support platform 1 is fixedly connected with a first storage cover 2 and a second storage cover 3 by bolts. The first storage cover 2 is located on one side of the second storage cover 3. Feed-in and discharge slots 4 are provided at the lower positions on the outer walls of one side of the first storage cover 2 and the second storage cover 3. Rod cylinders 5 are fixedly connected to the outer walls of the first storage cover 2 and the second storage cover 3 on the side far from the feed-in and discharge slots 4 by bolts. Electric push rods 6 are fixedly connected to the central positions on the outer walls of the rod cylinders 5 on the side far from the first storage cover 2 and the second storage cover 3 by bolts. The electric push rods 6 are fixedly connected with support rods 7 through the output ends on one side. Limiting rod holes 8 are provided at the positions on the outer walls of the first storage cover 2 and the second storage cover 3 close to the support rods 7. The bottom of the support platform 1 is fixedly connected with traveling wheels 9 by bolts. There are four traveling wheels 9 in total, and the four traveling wheels 9 are symmetrically arranged at the bottom of the support platform 1. The traveling wheels 9 are composed of brackets and wheels. A servo motor 10 is fixedly connected to the central position on the outer wall of one side of the support platform 1 by bolts. The servo motor 10 is fixedly connected with a ball screw 11 through the output end on one side. The nut seat on the ball screw 11 is fixedly connected with a moving plate 12 by screws. The moving plate 12 and the support platform 1 are slidably connected through sliders and chutes. The support platform 1 is of a hollow cuboid structure. A hydraulic cylinder 13 is fixedly connected to the top of the moving plate 12 by bolts. The hydraulic cylinder 13 is fixedly connected with a lifting plate 14 through the output end on one side. A through slot 15 is provided at the position directly above the hydraulic cylinder 13 on the top of the support platform 1. A first support platform 16 and a second support platform 17 are welded to the top of the lifting plate 14. There are two second support platforms 17 in total, and the two second support platforms 17 are symmetrically arranged on the top of the lifting plate 14. The first support platform 16 is located on one side of the second support platform 17. Subway shield segments 18 are placed on the tops of the first support platform 16 and the second support platform 17. Arc-shaped grooves matching the outer walls of the subway shield segments 18 are provided on the tops of the first support platform 16 and the second support platform 17.

[0024] It should be noted that since the upper subway shield segments are at a relatively high position after the existing subway shield segment transport racks stack the subway shield segments, due to the limited space in the tunnel, it is not convenient to lift and remove the stacked subway shield segments, which is not conducive to the subsequent installation of the subway shield segments. It is difficult for the transport rack to batch transport the subway shield segments. In this embodiment, through the support of the support rod 7 for the subway shield segment 18, the subway shield segments 18 are stacked at intervals, and by using the lifting of the subway shield segment 18 by the lifting plate 14 and the movement of the lifting plate 14 in the vertical and horizontal directions, the stacked subway shield segments 18 can be taken out from bottom to top without using lifting equipment for hoisting, reasonably utilizing the limited space in the tunnel, ensuring that the transport rack can transport more subway shield segments 18 in a single time to the greatest extent while not affecting the normal installation of the subway shield segments 18 in the tunnel.

[0025] Specifically, in this embodiment, the solution mainly includes a first storage cover 2, a second storage cover 3, and a lifting plate 14. When transporting subway shield segments 18 in a tunnel, the subway shield segments 18 are hoisted and stacked inside the first storage cover 2 and the second storage cover 3. The support rods 7 inside the first storage cover 2 and the second storage cover 3 support the subway shield segments 18. The subway shield segments 18 are stacked in a spaced manner inside the first storage cover 2 and the second storage cover 3. By rotating the walking wheels 9, the support platform 1 is moved in the tunnel. When it reaches the required position, the stacked subway shield segments 18 are taken off one by one by controlling the horizontal movement and lifting of the lifting plate 14. Specifically, the servo motor 10 is controlled to drive the ball screw 11 to rotate through the output end on one side. The moving plate 12 on the ball screw 11 moves inside the support platform 1, and the hydraulic cylinder 13 on the moving plate 12 moves synchronously. The lifting plate 14 at the output end of the hydraulic cylinder 13 moves horizontally synchronously. The lifting plate 14 passes through the feeding and discharging slot 4 and enters the inside of the first storage cover 2 and the second storage cover 3. The hydraulic cylinder 13 is controlled to drive the lifting plate 14 to move upward through the output end on one side. The first support platform 16 and the second support platform 17 on the lifting plate 14 rise synchronously. After the first support platform 16 and the second support platform 17 contact the subway shield segment 18 and lift it, the subway shield segment 18 is separated from the support rod 7. At this time, the electric push rod 6 drives the support rod 7 to be retracted into the rod barrel 5 through the output end on one side, and then the subway shield segment 18 is taken out of the first storage cover 2 and the second storage cover 3 by resetting the lifting plate 14. After the subway shield segment 18 is exposed, it can be installed and fixed on the inner wall of the tunnel by using equipment.

[0026] In a further preferred embodiment of the present invention, as Figure 1 shown, the feeding and discharging slot 4 allows the overall movement in and out of the subway shield segment 18 lifted by the first support platform 16 and the second support platform 17 on the lifting plate 14.

[0027] In this embodiment, the subway shield segment 18 can be taken out of the first storage cover 2 and the second storage cover 3, so that the subway shield segment 18 is exposed, facilitating its installation and fixation on the inner wall of the tunnel.

[0028] In a further preferred embodiment of the present invention, as Figure 1 、 Figure 2 and Figure 4 shown, a space for accommodating the support rod 7 is provided inside the rod barrel 5. The support rod 7 passes through the outer wall on one side of the first storage cover 2 and the second storage cover 3, and the support rod 7 passes through the limit rod hole 8.

[0029] In this embodiment, through the storage of the support rod 7, space can be provided for the downward movement of the subway shield segment 18, so that the subway shield segment 18 can be taken out without using a hoisting device, making reasonable use of the limited space in the tunnel, and the support rod 7 can be supported by the limit rod hole 8, which can ensure the stable support of the support rod 7 for the subway shield segment 18.
