Description

Technical Field

[0001] The present invention relates to the construction of tunnel anchors and inclined shafts for extra-large bridges, and particularly to an orbital transportation device for large-inclination tunnels that can automatically adjust its attitude. Background Art

[0002] At present, there is no set of safe and established construction plans for the construction of bridge tunnel anchors in China. The most time-consuming part of the anchor tunnel excavation is the muck transportation. In the past, the construction was carried out conservatively. Only the inclined shaft transportation technology could be used to reduce the capacity of the muck truck and transport it in multiple small batches. At the same time, as the tunnel angle increases, there is often a risk of accidental falling of the muck or materials, which also brings a series of safety problems. The existing conventional transportation equipment cannot be very safe in terms of loading and unloading. At the same time, the existing equipment has poor functionality and cannot well adjust its own state during transportation, being rather inflexible. Summary of the Invention

[0003] In view of the above problems, there is provided an orbital transportation device for large-inclination tunnels that can automatically adjust its attitude, so as to adjust its own attitude according to the angle at the bending point and thus cope with the tracks in tunnels of different angles.

[0004] An orbital transportation device for large-inclination tunnels that can automatically adjust its attitude includes a box body and a chassis. The chassis is installed at the bottom of the box body, and two sets of running wheel pairs are installed on the chassis. It is characterized in that it further includes a first auxiliary wheel pair. The first auxiliary wheel pair is located between the two sets of running wheel pairs, and the axle in the first auxiliary wheel pair is rotatably installed on the chassis.

[0005] Wherein, when the orbital transportation device moves to the bending point of the large-inclination track, the axle of the first auxiliary wheel pair rotates to make the auxiliary wheel pair touch the track to cooperate with the running wheel pairs to turn. After turning, the axle in the first auxiliary wheel pair rotates to make the auxiliary wheel pair derail, and the orbital transportation device uses the running wheel pairs to move forward.

[0006] Furthermore, the orbital transportation device further includes a second auxiliary wheel pair. The second auxiliary wheel pair is located between the first auxiliary wheel pair and the running wheel pairs, and the axle in the second auxiliary wheel pair is rotatably installed on the chassis.

[0007] Furthermore, lap columns are installed on both sides of the front part of the chassis. The tops of the lap columns are attached to the box body. The two sides of the tail of the chassis are rotatably installed on the box body through support hinges, and the box body can be rotated around the support hinges under the drive of a drive assembly to make the box body tilt towards the tail for discharging through the discharge opening at the tail of the box body.

[0008] Further, the driving assembly includes a driving slider, a first driving cylinder and a connecting rod. The driving slider is embedded in a chute on the chassis and can slide forward and backward along the chute. The first driving cylinder is installed on the chassis, and the driving head of the first driving cylinder is connected to the driving slider. The two ends of the connecting rod are rotatably installed on the driving slider and the box body respectively.

[0009] Further, a discharge plate is installed on the box body opposite to the discharge port. The upper sides of both ends of the discharge plate are rotatably installed on the box body. A discharge groove is formed in the discharge plate, and a discharge slider is embedded in the discharge groove. The discharge slider is rotatably connected to a second driving cylinder on the box body.

[0010] Further, the rail transportation device further includes a first rotating rod, a first axle box and a first auxiliary cylinder. The two ends of the first rotating rod are rotatably installed on the chassis. The axle of the first auxiliary wheel pair is fixedly installed on the first rotating rod through the first axle box. The first auxiliary cylinder is installed on the chassis, and the driving head of the first auxiliary cylinder is rotatably installed on the first axle box.

[0011] Further, the rail transportation device further includes a second rotating rod, a second axle box and a second auxiliary cylinder. The two ends of the second rotating rod are rotatably installed on the chassis. The axle of the second auxiliary wheel pair is fixedly installed on the second rotating rod through the second axle box. The second auxiliary cylinder is installed on the chassis, and the driving head of the second auxiliary cylinder is rotatably installed on the second axle box.

[0012] The beneficial effects of the above solution are:

[0013] In the present invention, when the rail transportation device moves to the curved part of the large-inclination track, the axle of the auxiliary wheel pair rotates to make the auxiliary wheel pair touch the rail, so as to cooperate with the running wheel pair to turn. After turning, the axle in the auxiliary wheel pair rotates to make the auxiliary wheel pair derail, and the rail transportation device uses the running wheel pair to run, so as to adapt to the turning needs of curved parts with different inclinations and maintain its own stability and ensure transportation safety.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not a limitation of the present invention.

[0022] As Figures 1 to 4 shown, the rail transportation device provided in the embodiment of the present invention includes a box body 1 and a chassis 2. The chassis 2 is installed at the bottom of the box body 1. Two sets of traveling wheel pairs 3 are installed on the chassis 2. It is characterized in that it further includes a first auxiliary wheel pair 4. The first auxiliary wheel pair 4 is located between the two sets of traveling wheel pairs 3. The axle in the first auxiliary wheel pair 4 is rotatably installed on the chassis 2;

[0023] As Figure 1 and Figure 4 shown, when the rail transportation device moves to the curved part of the large inclination track in the present invention, the axle of the first auxiliary wheel pair 4 rotates to make the auxiliary wheel pair touch the rail to cooperate with the traveling wheel pair 3 to turn. After turning, the axle in the first auxiliary wheel pair 4 rotates to make the auxiliary wheel pair derail, and the rail transportation device uses the traveling wheel pair 3 to travel. Specifically, in the present invention, the first rotating rod 16 can be rotatably installed on the chassis 2, and the rotating shaft in the first auxiliary wheel pair 4 can be fixedly installed on the first rotating rod 16 by using two first axle boxes 17, and then the first axle box 17 is driven by the first auxiliary cylinder 18 installed on the chassis 2 to drive the first rotating rod 16 to rotate, so as to release / retract the first auxiliary wheel pair 4.

[0024] On this basis, further, the rail transportation device provided in this embodiment further includes a second auxiliary wheel pair 5. The second auxiliary wheel pair 5 is located between the first auxiliary wheel pair 4 and the running wheel pair 3. The axle in the second auxiliary wheel pair 5 is rotatably installed on the chassis 2. In the present invention, when the inclination angle at the bending part is too large, the second auxiliary wheel pair 5 can be selectively released to utilize the second auxiliary wheel pair 5 to cooperate with the running wheel pair 3 and / or the first auxiliary wheel pair 4 to turn. Specifically, in the present invention, a second rotating rod 19 can be rotatably installed on the chassis 2, and the rotating shaft in the second auxiliary wheel pair 5 can be fixedly installed on the second rotating rod 19 by corresponding two second axle boxes 20. Then, the second auxiliary cylinder 21 installed on the chassis 2 is used to drive the second axle box 20, so as to drive the second rotating rod 19 to rotate, so as to release / retract the second auxiliary wheel pair 5.

[0025] On this basis, furthermore, to facilitate the discharging of the box body 1, in the present invention, overlapping columns 6 are installed on both sides of the front part of the chassis 2. The top of the overlapping column 6 is attached to the box body 1. Both sides of the rear part of the chassis 2 are rotatably installed on the box body 1 through support hinges 7. In this way, the box body 1 can be rotated around the support hinge 7 under the drive of the drive assembly to tilt the box body 1 towards the tail, so as to discharge through the discharge port at the tail of the box body 1. Specifically, the above drive assembly includes a drive slider 8, a first drive cylinder 9 and a connecting rod 10. The drive slider 8 is embedded in the chute 11 on the chassis 2. The drive slider 8 can slide forward and backward along the chute 11. The first drive cylinder 9 is installed on the chassis 2, and the drive head of the first drive cylinder 9 is connected to the drive slider 8. Both ends of the connecting rod 10 are correspondingly rotatably installed on the drive slider 8 and the box body 1. In the present invention, when the first drive cylinder 9 pushes the drive slider 8 forward, the connecting rod 10 jacks up the front part of the box body 1, so that the box body 1 rotates around the support hinge 7, so as to discharge through the discharge port at the tail of the box body 1. To facilitate the control of the discharge plate 12 (the upper two sides of the discharge plate 12 are rotatably installed on the box body 1) on the discharge port, a discharge chute 13 can be opened on the discharge plate 12 correspondingly. A discharge slider 14 (the discharge slider 14 can reciprocate in the discharge chute 13) is embedded in the discharge chute 13. The discharge slider 14 is rotatably connected to the second drive cylinder 15 on the box body 1, so as to drive the discharge slider 14 through the second drive cylinder 15, so as to drive the discharge plate 12 to open and close the discharge port.

[0026] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention accordingly. For those skilled in the art, it should be able to realize that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
