Description

Technical Field

[0001] The utility model relates to the technical field of tunnel transportation equipment, in particular to a tunnel vehicle passing device. Background Art

[0002] Compared to traditional mining-based tunnel construction, shield tunneling boasts a high degree of mechanization, high efficiency, and superior safety, making it increasingly widely used in underground engineering. During shield tunneling, horizontal transportation of segments, grouting materials, and slag requires rail-mounted electric vehicles. Even shield tunnels that utilize a horizontal continuous belt for slag removal still require rail-mounted electric vehicles for transporting segments and other materials. Once a shield tunnel reaches a certain length, horizontal transportation of slag and other materials within the tunnel becomes a major constraint on construction progress, necessitating the addition of horizontal rail-mounted electric vehicles to address this transportation challenge. For urban rail transit projects, switches can be installed at the shield tunnel's departure station to address the issue of slag vehicles running side-by-side. However, shield tunneling using other methods, such as split departure or ventilation shaft departure, often precludes the installation of switches within the departure shaft due to the insufficient length of the departure shaft.

[0003] To solve this problem, a Chinese patent document with publication number CN221956444U discloses a switch device for improving shield construction efficiency in a narrow space. The tunnel in this patent document is divided into a working shaft, a slope-changing section, and a normal section. Sleepers are laid on the bottom wall surface of the tunnel at intervals along the length of the tunnel. A single track is laid on the sleepers in the slope-changing section and the normal section of the tunnel, and a double track is laid at the working shaft, with a switch between the single track and the double track. By adding a switch in the tunnel, two trains of electric vehicles can pass each other and operate synchronously in a narrow tunnel. However, the double track is fixed at the working shaft and the slope-changing section is also fixed. In this way, the passing position is fixed and cannot meet the passing needs of different positions. In addition, the single track on the slope-changing section is tilted, and the working vehicle must go up to the double track via the inclined single track, which makes it difficult to meet the passing requirements of working vehicles that cannot be tilted.

[0028] Example 1

[0029] Figures 1 to 5 An embodiment of the tunnel passing device of the present invention is shown. The tunnel passing device of this embodiment includes a driving track 1 arranged at the bottom of the tunnel. A passing frame 3 and two docking frames 2 are movably provided on the driving track 1. The two docking frames 2 are respectively located at the two ends of the passing frame 3. The passing frame 3 is provided with a first track 5 and a second track 6. The docking frame 2 is provided with a docking track 4. The first track 5 and the second track 6 are higher than the driving track 1. One end of the docking track 4 is used for docking with the driving track 1, and the other end is used for docking with the first track 5 and the second track 6.

[0030] In the tunnel passing device of this embodiment, a passing frame 3 and two docking frames 2 are movably provided on a driving track 1. The passing frame 3 is provided with a first track 5 and a second track 6, and the docking frames 2 are provided with a docking track 4. The docking track 4 can dock the driving track 1 with the first track 5, or with the driving track 1 with the second track 6. Two working vehicles that need to pass each other can respectively pass the docking tracks 4 on the two docking frames 2 and onto the first track 5 and the second track 6 for passing. Since both the passing frame 3 and the docking frames 2 are movable on the driving track 1, they can be moved to a suitable location on the driving track 1 according to actual use needs, thereby meeting the needs of passing vehicles at different locations.

[0031] The operation process of the tunnel passing device of this embodiment is as follows: first, the passing frame 3 and the two docking frames 2 are moved to the position where the passing is required; then, one end of each docking rail 4 is docked with the driving rail 1, and the other end is docked with the first rail 5 and the second rail 6; then, the working vehicles that need to pass each other are moved to the two ends of the tunnel passing device respectively, and the working vehicle at one end of the tunnel passing device enters the first rail 5 or the second rail 6 through the docking rail 4 on the docking frame 2 at that end, and the working vehicle at the other end of the tunnel passing device enters the second rail 6 or the first rail 5 through the docking rail 4 on the docking frame 2 at that end; finally, the working vehicles on the first rail 5 and the second rail 6 continue to move in the forward direction, and move to the driving rail 1 through the corresponding docking rail 4 to complete the passing. Figure 5 Furthermore, in this embodiment, a first running wheel 31 is provided at the bottom of the staggered frame 3, and the first running wheel 31 is supported on the driving track 1. Preferably, a plurality of first running wheels 31 are provided on both sides of the bottom of the staggered frame 3 at intervals along the length direction of the staggered frame 3, which is conducive to ensuring the stability of the staggered frame 3 during movement.

[0032] See Figure 6 Furthermore, in this embodiment, the bottom of the docking frame 2 is provided with a second running wheel 21, and the second running wheel 21 is supported on the driving track 1. Preferably, a plurality of second running wheels 21 are provided on both sides of the bottom of the docking frame 2 at intervals along the length direction of the staggered frame 3, which is conducive to ensuring the stability of the docking frame 2 during movement.

[0033] Furthermore, in this embodiment, the docking frame 2 is fixedly connected to the staggered frame 3. This helps ensure the stability of the working vehicle when it travels through the docking track 4 to the first track 5 or the second track 6. Of course, in other embodiments, the docking frame 2 may not be connected to the staggered frame 3.

[0034] See Figures 1 to 3 Furthermore, in this embodiment, switches 7 are provided at both ends of the staggered frame 3, and the first track 5 and the second track 6 are docked with the docking track 4 through the switches 7. The switches 7 facilitate the selective entry of working vehicles from the docking track 4 into the first track 5 and the second track 6, and also facilitate the entry of vehicles from the first track 5 and the second track 6 into the docking track 4, and are reliable and stable to use.

[0035] Example 2

[0036] Figures 6 and 7 Another embodiment of the tunnel passing device of the present invention is shown. The tunnel passing device of this embodiment is roughly the same as that of the first embodiment, except that, in this embodiment, a lifting mechanism 8 is provided on the docking frame 2, and the docking track 4 is provided on the lifting mechanism 8 and can be adjusted to a horizontal state.

[0037] In the tunnel passing device of this embodiment, the lifting mechanism 8 can adjust the docking track 4 to a horizontal state. The lifting mechanism 8 can also be raised and lowered to switch the docking track 4 to the driving track 1 or the switch 7. When the docking track 4 is adjusted to a horizontal state and docks with the driving track 1, the working vehicle can move from the driving track 1 to the docking track 4, or from the docking track 4 to the driving track 1; when the docking track 4 is adjusted to a horizontal state and docks with the switch 7, the working vehicle can move from the docking track 4 to the switch 7, or from the switch 7 to the docking track 4. Furthermore, the lifting mechanism 8 can maintain the working vehicle in a horizontal state while transporting it between the driving track 1 and the switch 7. In this way, the working vehicle can always remain horizontal when moving between the tracks, avoiding tilting movement due to climbing a slope and meeting the passage needs of working vehicles that cannot move tilting.

[0038] See Figure 6 and Figure 7 Furthermore, in this embodiment, the lifting mechanism 8 includes two sets of lifting assemblies 81, both of which are arranged on the docking frame 2, and the two ends of the docking track 4 are respectively arranged on the two sets of lifting assemblies 81. Specifically, one set of lifting assemblies 81 is supported on one end of the docking track 4, and the other set of lifting assemblies 81 is supported on the other end of the docking track 4. The two sets of lifting assemblies 81 can be raised and lowered synchronously to make the docking track 4 horizontal. That is, the two sets of lifting assemblies 81 can be raised and lowered synchronously to realize the transportation of the working vehicle between the driving track 1 and the switch 7. In addition, the lifting assembly 81 close to the switch 7 can be raised and lowered to realize the conversion of the docking track 4 between the inclined and horizontal states (at this time, the lifting assembly 81 far away from the switch 7 can be maintained in a low position, so that the docking track 4 is docked with the driving track 1). The lifting assembly 81 is a conventional component with a lifting function.

[0039] Furthermore, in this embodiment, the docking frame 2 is provided with a locking mechanism 9 for locking the lifting mechanism 8. When the docking track 4 is in an inclined state connected to the driving track 1 and the switch 7, the locking mechanism 9 locks the lifting mechanism 8, thereby preventing the lifting movement of the lifting mechanism 8, thereby ensuring stability during vehicle passage. Specifically, the lifting mechanism 8 may include a lifting frame and a lifting drive member. The bottom end of the lifting drive member is fixed to the docking frame 2, and the top end of the lifting drive member is hinged to the docking track 4. The locking mechanism includes a locking member, such as a locking bolt or locking pin, provided on the docking frame 2. The locking member is inserted into the lifting frame to lock the lifting frame. The lifting drive member may be an oil cylinder, a pneumatic cylinder, or an electric cylinder.

[0040] See Figure 6 and Figure 7Furthermore, in this embodiment, the docking frame 2 is provided with a low-position stopper 22 at the lower end of the lifting assembly 81 for preventing the lifting assembly 81 from descending, and a high-position stopper 23 at the upper end of the docking frame 2 for preventing the lifting assembly 81 from ascending. The docking frame 2 is provided with a low-position stopper 22 below each group of lifting assemblies 81 and a high-position stopper 23 above each lifting assembly 81. The docking frame 2 is provided with a high-position stopper 23 above each lifting assembly 81. The low-position stopper 22 is used to block below the lifting assembly 81 to limit the minimum height of the docking track 4, and the high-position stopper 23 is used to block above the lifting assembly 81 to limit the maximum height of the docking track 4, thereby limiting the lifting and tilting range of the docking track 4. Preferably, the low-position stopper 22 and the high-position stopper 23 are respectively blocked at the upper and lower parts of the lifting frame to limit the lifting range of the lifting frame.

[0041] like Figure 6 As shown, when the lifting frames of the two lifting assemblies 81 are against the corresponding low-position blocking members 22, it means that the docking track 4 is in a horizontal state and has been lowered into place. At this time, the docking track 4 is docked with the driving track 1; Figure 7 As shown, when the lifting frames of the two lifting assemblies 81 are both against the corresponding high-position blocking pieces 23, it means that the docking track 4 is in a horizontal state and has risen to its full position, and the docking track 4 is docked with the switch 7. When the lifting frame of the lifting assembly 81 close to the switch 7 is against the upper high-position blocking piece 23 and the lifting frame of the lifting assembly 81 away from the switch 7 is against the lower low-position blocking piece 22, the docking track 4 is in an inclined state, and its two ends are respectively docked with the driving track 1 and the switch 7. This helps to ensure that the docking track 4 can dock with the corresponding track quickly and accurately.
