Description

Technical Field

[0001] This application relates to the field of engineering transportation, and particularly to a platform for passing vehicles in a tunnel. Background Art

[0002] During the construction of a water conveyance tunnel, small transport vehicles are required to transport materials in the water conveyance tunnel. Usually, the cross-section of the water conveyance tunnel is circular, and there is a two-meter-wide platform at the bottom of the water conveyance tunnel. The platform can be used for staff to walk on and small transport vehicles to pass through.

[0003] However, since the width of the tunnel platform is only two meters, which is relatively narrow, only one small transport vehicle can travel unidirectionally in the tunnel, and it is impossible to complete actions such as turning around. It can only move forward and backward. At present, it is necessary for the staff to manually lift the small transport vehicle to turn around so that the small transport vehicle can carry out transportation. However, this method increases the safety hazards of the staff and limits the flexibility and transportation efficiency of transportation. Summary of the Invention

[0004] In order to reduce the safety hazards of the staff and improve the flexibility and transportation efficiency of transportation, this application provides a platform for passing vehicles in a tunnel.

[0005] The platform for passing vehicles in a tunnel provided by this application adopts the following technical solutions:

[0006] A platform for passing vehicles in a tunnel includes a track group installed in the tunnel for the movement of small transport vehicles and staff, and a plurality of infrared pair-emitting devices installed on both sides of the track group. A moving component for controlling the vertical movement of the track group is installed on one side of the track group. A platform for support is arranged below the moving component and the guide rail group; the track group includes annular tracks installed at both ends of the tunnel, a first connecting track connected to one end of one of the annular tracks, and a second connecting track connected to one end of the other annular track. The end of the first connecting track far from the annular track is connected to the end of the second connecting track far from the annular track. A third connecting track is connected between the other ends of the two annular tracks. The two annular tracks, the first connecting track, the second connecting track, and the third connecting track enclose a complete trajectory and form a space therebetween. A first conversion track and a second conversion track are installed in the space. The first conversion track, the track group, and the second conversion component are arranged in three spaces from top to bottom in sequence; when the moving component is used, the second connecting track can be connected to the first conversion track to form a new movement route, and the first connecting track can also be connected to the second conversion track.

[0007] By adopting the above technical solution, when there are staff members using small transport vehicles at both ends of the tunnel, the staff members and the small transport vehicles pass through the infrared pair emission device. When the infrared pair emission device detects the staff members and the small transport vehicles, the moving component is activated, causing the first conversion track and the second conversion track to rise and connect with the first connection track and the second connection track respectively. The staff members on both sides move to both ends of the third connection track from the first conversion track and the second conversion track respectively, thus realizing the passing of vehicles for the staff members at both ends of the tunnel. When the same vehicle needs to travel from one end of the tunnel to the other end and then complete the U-turn operation, it can directly pass through the track group and make one round trip, without the need for the staff members to manually lift the small transport vehicle for a U-turn, thereby reducing the safety hazards for the staff members and improving the flexibility and transportation efficiency of the transportation.

[0008] Optionally, the height difference between the first conversion track and the second conversion track is not less than 2m.

[0009] By adopting the above technical solution, when a U-turn is not required, to facilitate the travel of the staff members and the small transport vehicles, the first conversion track and the second conversion track use the moving component to form a height difference, enabling the staff members and the small transport vehicles to pass more smoothly.

[0010] Optionally, the moving component includes a rack installed on one side of the first connection track and a gear meshing with the rack. A driving motor for rotating the gear is installed on the platform, and the gear is sleeved on the output shaft of the driving motor.

[0011] By adopting the above technical solution, when there are staff members using small transport vehicles at both ends of the tunnel, the driving motor is started. The output shaft of the driving motor drives the gear to rotate, and the rack meshing with the gear moves upward, thereby driving the first conversion track and the second conversion track to move, making the first conversion track abut against the second connection track and the second conversion track abut against the first connection track, enabling the staff members at both ends to push the small transport vehicles to realize passing of vehicles.

[0012] Optionally, a fixed rod is installed on the side of the first conversion track away from the rack. A sliding groove is formed along the length direction of the fixed rod. The fixed rod is slidably connected with a slider, and the slider is connected with the first connection track.

[0013] By adopting the above technical solution, when the first conversion track moves, the fixed rod slides along the sliding groove. The sliding groove guides the moving direction of the first conversion track, enabling the first conversion track to abut against the second connection track.

[0014] Optionally, the infrared pair emission device is used to detect whether the small transport vehicle reaches the designated position on the track group. The infrared pair emission device includes a signal emitter arranged on one side of the first connection track and a signal receiver arranged on the other side of the first connection track for receiving the signal emitted by the signal emitter.

[0015] By adopting the above technical solution, when the staff pushes the small transport vehicle between the signal transmitter and the signal receiver, the signal receiver controls the driving motor to start running, so that the moving component starts to abut the first conversion track against the second connection track.

[0016] Optionally, a limiting component for preventing the small transport vehicle from derailing is provided at one end of the first connection track. The limiting component includes a hydraulic rod hinged on the platform and a blocking frame connected to the end of the hydraulic rod far from the platform. The end of the blocking frame far from the hydraulic rod is hinged to the first connection track.

[0017] By adopting the above technical solution, when the staff pushes the small transport vehicle beyond the connection between the first connection track and the second conversion track, the hydraulic rod is started. Since the length of the blocking frame remains unchanged, the hydraulic rod drives the blocking frame to rotate around the hinge axis with the first connection track, so that the blocking frame blocks the continuously running small transport vehicle and prevents it from colliding with the small transport vehicle at the other end of the tunnel.

[0018] Optionally, a plurality of telescopic rods are provided between the first conversion track and the platform.

[0019] By adopting the above technical solution, the telescopic rods support the first conversion track and move along with the first conversion track, making the structural strength of the first conversion track higher, and the telescopic rods can move along with the first conversion track to adapt to the movement track of the first conversion track.

[0020] Optionally, support rods are installed at the bottom of the platform. The ends of the support rods far from the platform are fixedly connected to the tunnel wall. A plurality of support rods are arranged along the length direction of the platform.

[0021] By adopting the above technical solution, the support rods play a supporting role for the platform, thereby ensuring the supporting strength of the platform for the track group, enabling the platform to better support the track group, and further ensuring the transportation safety of the staff.

[0022] Optionally, the support rods are inclined, and the space cross-section formed by the support rods, the platform and the tunnel is triangular.

[0023] By adopting the above technical solution, the triangular cross-section design makes the supporting strength of the support rods for the plane stronger, enables the platform to further strengthen the support for the track group, and at the same time can further strengthen the safety guarantee for the staff.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up an orbital group, an infrared pair emission device, a moving component, and a platform, when the moving component is used, the orbital group can form a new movement route. When there are staff members using small transport vehicles at both ends of the tunnel, the staff members and the small transport vehicles pass through the infrared pair emission device. The infrared pair emission device detects the staff members and the small transport vehicles, activates the moving component, and the staff members on both sides walk out from the new orbits respectively, thus realizing the passing of the staff members at both ends of the tunnel. When there is no need for a U-turn, for the convenience of the driving of the staff members and the small transport vehicles, the first conversion orbit and the second conversion orbit are used by the moving component to form a height difference, so that the staff members and the small transport vehicles can pass more smoothly, without the need for the staff members to manually lift the small transport vehicle for a U-turn, thereby reducing the safety hazards of the staff members and improving the flexibility and transportation efficiency of the transportation;

[0026] 2. By setting up an annular orbit, a first connecting orbit, a second connecting orbit, a first conversion orbit, a second conversion orbit, and a third connecting orbit, when the moving component is used, the second connecting orbit can be connected to the first conversion orbit to form a new movement route, and the first connecting orbit can also be connected to the second conversion orbit. The staff members on both sides move from the first conversion orbit and the second conversion orbit to both ends of the third connecting orbit respectively, thus realizing the passing of the staff members at both ends of the tunnel;

[0027] 3. By setting up a rack, a gear, a driving motor, a fixed rod, and a sliding groove, when there are staff members using small transport vehicles at both ends of the tunnel, the driving motor is started, the output shaft of the driving motor drives the gear to rotate, and the rack engaged with the gear moves upward, thereby driving the first conversion orbit and the second conversion orbit to move, so that the first conversion orbit abuts against the second connecting orbit, and the second conversion orbit and the first connecting orbit abut against each other, enabling the staff members at both ends to push the small transport vehicles to realize passing.

[0033] The following further elaborates on this application Figures 1-4 with reference to the accompanying drawings.

[0034] An embodiment of this application discloses a platform for passing vehicles in a tunnel.

[0035] Referring to Figure 1 , a platform for passing vehicles in a tunnel includes a track group 1 installed in the tunnel for the movement of small transport vehicles and staff, and a plurality of infrared pair emitters 3 installed on both sides of the track group 1. A moving assembly 2 for controlling the vertical up and down movement of the track group 1 is installed on one side of the track group 1, and a platform 7 for support is arranged below the moving assembly 2 and the guide rail group.

[0036] The track group 1 includes a ring track 11 installed at both ends of the tunnel, a first connecting track 12 connected to one end of one ring track 11, and a second connecting track 13 connected to one end of the other ring track 11. The end of the first connecting track 12 far from the ring track 11 is connected to the end of the second connecting track 13 far from the ring track 11. A third connecting track 14 is connected between the other ends of the two ring tracks 11. A complete trajectory is formed among the two ring tracks 11, the first connecting track 12, the second connecting track 13, and the third connecting track 14, and a space is formed therebetween. A first conversion track 15 and a second conversion track 16 are installed in the space. The first conversion track 15, the track group 1, and the second conversion assembly are sequentially arranged in three spaces from top to bottom. The height difference between the first conversion track 15 and the second conversion track 16 is not less than 2m.

[0037] When the moving component 2 is used, the second connecting track 13 can be connected to the first conversion track 15 to form a new movement route, and the first connecting track 12 can also be connected to the second conversion track 16. When there are staff members using small transport vehicles at both ends of the tunnel, the staff members and the small transport vehicles pass through the infrared pair emission device 3. The infrared pair emission device 3 detects the staff members and the small transport vehicles and starts the moving component 2, causing the first conversion track 15 and the second conversion track 16 to rise and connect to the first connecting track 12 and the second connecting track 13 respectively. The staff members on both sides move from the first conversion track 15 and the second conversion track 16 to both ends of the third connecting track 14 respectively, thus realizing the passing of the staff members at both ends of the tunnel. When there is no need to make a U-turn, for the convenience of the driving of the staff members and the small transport vehicles, the first conversion track 15 and the second conversion track 16 are made to form a height difference by using the moving component 2, enabling the staff members and the small transport vehicles to pass more smoothly without the need for the staff members to manually lift the small transport vehicle for a U-turn, thereby reducing the safety hazards of the staff members and improving the flexibility and transportation efficiency of the transportation.

[0038] Refer to Figure 1 and Figure 2 , the moving component 2 includes a rack 21 installed on one side of the first connecting track 12 and a gear 22 meshing with the rack 21. A driving motor 23 for rotating the gear 22 is installed on the platform 7, and the gear 22 is sleeved on the output shaft of the driving motor 23. When there are staff members using small transport vehicles at both ends of the tunnel, the driving motor 23 is started. The output shaft of the driving motor 23 drives the gear 22 to rotate, and the rack 21 meshing with the gear 22 moves upward, thereby driving the first conversion track 15 and the second conversion track 16 to move, so that the first conversion track 15 abuts against the second connecting track 13, and the second conversion track 16 abuts against the first connecting track 12, enabling the staff members at both ends to push the small transport vehicles to realize passing.

[0039] A fixing rod 4 is installed on the side of the first conversion track 15 away from the rack 21. A sliding groove 5 is formed along the length direction of the fixing rod 4. The fixing rod 4 is slidably connected with a slider 6, and the slider 6 is connected to the first connecting track 12. When the first conversion track 15 moves, the fixing rod 4 slides along the sliding groove 5, and the sliding groove 5 guides the moving direction of the first conversion track 15, enabling the first conversion track 15 to abut against the second connecting track 13.

[0040] Refer to Figure 1, the infrared pair device 3 is used to detect whether the small transport vehicle reaches the designated position on the track group 1. The infrared pair device 3 includes a signal transmitter 31 arranged on one side of the first connecting track 12 and a signal receiver 32 arranged on the other side of the first connecting track 12 for receiving the signal emitted by the signal transmitter 31. When the staff pushes the small transport vehicle between the signal transmitter 31 and the signal receiver 32, the signal receiver 32 controls the driving motor 23 to start running, so that the moving component 2 makes the first conversion track 15 abut against the second connecting track 13.

[0041] Refer to Figure 3 and Figure 4 , a limiting component 8 for preventing the small transport vehicle from derailing is arranged at one end of the first connecting track 12. The limiting component 8 includes a hydraulic rod 81 hinged on the platform 7 and a blocking frame 82 connected to the end of the hydraulic rod 81 away from the platform 7. One end of the blocking frame 82 away from the hydraulic rod 81 is hinged to the first connecting track 12. When the staff pushes the small transport vehicle beyond the connection between the first connecting track 12 and the second conversion track 16, the hydraulic rod 81 is started. Since the length of the blocking frame 82 remains unchanged, the hydraulic rod 81 drives the blocking frame 82 to rotate around the hinge axis with the first connecting track 12, so that the blocking frame 82 blocks the continuously running small transport vehicle to avoid collision with the small transport vehicle at the other section of the tunnel.

[0042] A plurality of telescopic rods (not shown in the figure) are arranged between the first conversion track 15 and the platform 7. The telescopic rods support the first conversion track 15 and move along with the first conversion track 15, so that the structural strength of the first conversion track 15 is higher, and the telescopic rods can move along with the first conversion track 15 to adapt to the movement track of the first conversion track 15.

[0043] Support rods 9 are installed at the bottom of the platform 7. One end of the support rod 9 away from the platform 7 is fixedly connected to the tunnel wall. A plurality of support rods 9 are arranged along the length direction of the platform 7. The support rods 9 are inclined. The space cross-section formed by the support rods 9, the platform 7 and the tunnel is triangular.

[0044] Refer to Figure 3 , the support rods 9 play a supporting role for the platform 7, so as to ensure the supporting strength of the platform 7 for the track group 1, so that the platform 7 can better support the track group 1, and further ensure the transportation safety of the staff. The triangular cross-section design makes the supporting strength of the support rods 9 for the plane stronger, so that the platform 7 can further strengthen the support for the track group 1, and at the same time can further strengthen the safety guarantee for the staff.

[0045] The implementation principle of a platform for passing vehicles in a tunnel in an embodiment of the present application is as follows: When the staff pushes a small transport vehicle between the signal transmitter 31 and the signal receiver 32, the signal receiver 32 controls the drive motor 23 to start running. The output shaft of the drive motor 23 drives the gear 22 to rotate, and the rack 21 meshing with the gear 22 moves upward, thereby driving the first conversion track 15 and the second conversion track 16 to move, so that the first conversion track 15 abuts against the second connection track 13, and the second conversion track 16 abuts against the first connection track 12. At the same time, the telescopic rod supports the first conversion track 15 and moves along with the first conversion track 15 to form two loops, thereby realizing the passing of vehicles for the staff at both ends of the tunnel. When the staff pushes the small transport vehicle beyond the connection between the first connection track 12 and the second conversion track 16, the hydraulic rod 81 is activated. Since the length of the blocking frame 82 remains unchanged, the hydraulic rod 81 drives the blocking frame 82 to rotate around the hinge shaft with the first connection track 12..

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
