Description

Technical Field

[0001] The present application relates to the technical field of tunnel excavation, and in particular to a slag bucket flap of an electric locomotive during tunnel excavation. Background Art

[0002] Currently in tunnel excavation, since a large amount of debris is generated during the tunneling process of the shield machine, it is often necessary to use a rail electric locomotive with a debris bucket to collect and process the debris generated by the shield machine excavation.

[0003] In the prior art, when collecting and processing the slag generated by shield machine excavation, it is often necessary to use a belt to transport the slag to the slag bucket of a moving rail electric locomotive, and then the rail electric locomotive will transport the slag out for processing.

[0004] During their research and improvement, the R&D personnel found that due to the gaps between the slag buckets of the rail electric locomotives, when transporting the slag into the slag buckets, the rail electric locomotives need to be parked at the belt discharge port in turn according to the position of the slag buckets. During this process, the excavation equipment will be shut down, and there is a defect that continuous excavation cannot be achieved when the rail electric locomotive receives the slag, which reduces the excavation efficiency. Utility Model Content

[0005] In order to enable the excavation equipment to continuously excavate when the rail electric locomotive receives slag and improve the excavation efficiency, the present application provides a slag bucket flap for the electric locomotive during tunnel excavation.

[0006] The present application provides a motor vehicle for tunnel excavation. The slag bucket flap adopts the following technical solution:

[0007] A slag bucket flap for an electric locomotive during tunnel excavation comprises a rotating column and a flap, wherein the rotating column is arranged in a vertical direction, the rotating column is located inside the slag bucket and respectively located at two ends of the slag bucket along the running direction of the electric locomotive, the flap is located above the slag bucket, the flap comprises a connecting plate and a flipping plate, the connecting plate is located above the slag bucket bin, the connecting plate is arranged horizontally and is rotatably connected to the end face of the rotating column away from the ground, the flipping plate is hinged to the side wall of the connecting plate away from the slag bucket, the hinge axis is arranged along the length of the side wall, and the flipping plates between adjacent slag buckets are detachably connected.

[0008] By adopting the above technical scheme, due to the setting of the rotating column and the flap, the gaps between the slag buckets of the rail electric locomotive are connected. Without affecting the movement of the rail electric locomotive, the slag transmitted to the slag bucket gaps by the belt can be taken over, so that the excavation equipment can continue to excavate when the rail electric locomotive receives the slag, thereby improving the excavation efficiency.

[0009] Optionally, a rotating motor is fixed on each connecting plate, and a rotating shaft of the rotating motor passes through the connecting plate. The rotating shaft of the rotating motor is arranged in the same direction as the hinge axis of the flip plate and the connecting plate and is fixedly connected.

[0010] By adopting the above technical solution, due to the setting of the rotating motor, the adjacent flip plates are disconnected and then flipped into the corresponding slag bucket by the rotating motor. This makes it easier to clean the debris on the flip plates and reduces the interference from the flip plates encountered by the staff when operating the equipment to unload the slag bucket.

[0011] Optionally, a flange guard plate is fixed on each connecting plate, and the flange guard plate is located above the rotating motor and shields the rotating motor.

[0012] By adopting the above technical solution and setting the flange guard plate, the occurrence of damage to the rotating motor caused by falling debris is reduced.

[0013] Optionally, a baffle is fixed on each flip plate, the baffle is located on the flip plate, and the baffle is used to prevent the debris from falling from the flip plate when the flip plate is folded into the hopper.

[0014] By adopting the above technical solution and setting the baffle, the occurrence of debris falling onto the track when being conveyed to the rail electric locomotive is reduced.

[0015] Optionally, connecting clips are provided on adjacent flip plates, and the connecting plates are used to connect the flip plates between adjacent hoppers.

[0016] Optionally, a limit plate is fixed on each connecting plate, and the limit plate is located below the connecting plate and extends to below the flip plate.

[0017] Optionally, a buffer ring is provided on the connecting plate, and the buffer ring is sleeved on the rotating connection between the connecting plate and the rotating column. The buffer ring is used to reduce the extrusion and friction of the rotating column when the connecting plate rotates.

[0018] Optionally, both the connecting plate and the flip plate are coated with an anti-rust layer for preventing the connecting plate and the flip plate from rusting.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. Due to the setting of the rotating column and the flap, the gaps between the slag buckets of the rail electric locomotive are connected, and the slag transferred to the slag bucket by the belt can be received without affecting the movement of the rail electric locomotive, so that the excavation equipment can continue to excavate when the rail electric locomotive receives the slag, thereby improving the excavation efficiency;

[0021] 2. Due to the setting of the rotating motor, after the adjacent flip plates are disconnected, they are flipped into the corresponding slag buckets through the rotating motor. This makes it easier to clean the slag on the flip plates and reduces the interference from the flip plates encountered by the staff when operating the equipment to unload the slag buckets.

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] The embodiment of the present application discloses a slag bucket flap of an electric locomotive during tunnel excavation.

[0028] Reference Figure 1 A bucket flap of an electric locomotive during tunnel excavation includes a rotating column 1 and a flap 2. In this embodiment, two rotating columns 1 and two flaps 2 are arranged in the bucket of each rail electric locomotive. The rotating columns 1 are arranged in the vertical direction and fixed on the inner wall of the bucket close to the ground. The rotating columns 1 are respectively located at both ends of the bucket along the moving direction of the rail electric locomotive. The flaps 2 correspond to the rotating columns 1 one by one. The flaps 2 are all arranged horizontally and rotatably connected to the upper part of the corresponding rotating columns 1. The flaps 2 close to each other between adjacent buckets can be detachably connected. During the excavation of the excavation equipment, when the rail electric locomotive is continuously running, the excavation equipment can be operated without stopping, and the slag can be transmitted in the transmission sequence of bucket-flap 2-bucket. At this time, the excavation equipment can continue to excavate without stopping.

[0029] refer to Figure 1 and Figure 2 Each flap 2 includes a connecting plate 21 and a flip plate 22. The connecting plate 21 is horizontally arranged and located above the bucket bin. The connecting plate 21 is rotatably connected to the upper part of the corresponding rotating column 1. The flip plate 2 is horizontally arranged and hinged to the vertical side wall of the corresponding connecting plate 21 away from the bucket, and the hinge axis is arranged along the length of the side wall. The surface of the connecting plate 21 and the flip plate 22 are coated with an anti-rust layer 5. In this embodiment, the anti-rust layer 5 can be an epoxy zinc-rich anti-rust layer 5. A rotating motor 3 is installed on each connecting plate 21. The rotating motor 3 is fixed on the vertical side wall of the connecting plate 21 along the direction of travel of the rail motor vehicle, and the rotating motors 3 are all located on the same side. The rotating shaft of the rotating motor 3 passes through the side wall and is fixedly connected to the hinge shaft of the flip plate 22 and the connecting plate 21. The rotating motor 3 can drive the corresponding flip plate 22 to flip into the inside of the bucket, and make the slag on the flip plate 22 fall into the bucket.

[0030] refer to Figure 2 and Figure 3 , each connecting plate 21 is fixed with a flange guard plate 211 and a limit plate 212. The flange guard plate 211 is horizontally arranged and fixed to the side wall where the rotating motor 3 is located. The flange guard plate 211 is located above the rotating motor 3 and blocks the rotating motor 3. When the slag falls, it will be blocked by the flange guard plate 211 to avoid damaging the rotating motor 3. The limit plate 212 is horizontally arranged and fixed below the corresponding connecting plate 21. The limit plate 212 extends to the bottom of the flip plate 22 hinged to the corresponding connecting plate 21 and abuts against the flip plate 22. Each flip plate 22 is provided with a baffle 221. The baffle 221 is arranged in the vertical direction. The baffle 221 is fixed to the side wall of the corresponding flip plate 22 away from the ground, and the side wall is away from the circumferential enclosure of the slag bucket. The baffle 221 is used to enclose the slag that falls on the flip plate 22 to the flip plate 22. A connecting clip 4 is provided on the flip plate 22. The connecting clip 4 is a strip-shaped clip with a downward groove. The connecting clip 4 is located between the flip plates 22 at the intervals between adjacent buckets. The connecting clip 4 is embedded in the adjacent baffles 221 and is threadedly connected to the adjacent baffles 221 by bolts.

[0031] refer to Figure 3 A buffer ring 11 is provided on each rotating column 1. In this embodiment, the buffer ring 11 can be a rubber ring. The buffer ring 11 is sleeved on the upper part of the corresponding rotating column 1 and is located between the connecting plate 21 and the rotating connection of the rotating column 1. The buffer ring 11 is used to reduce the squeezing and friction of the connecting plate 21 on the rotating column 1 when the rail electric locomotive turns.

[0032] The implementation principle of the bucket flap of an electric locomotive in tunnel excavation is as follows: the setting of the rotating column 1 and the flap 2 connects the gaps between the buckets of the rail electric locomotive, and can receive the slag transferred to the bucket interval by the belt without affecting the movement of the rail electric locomotive, so that the excavation equipment can continue to excavate when the rail electric locomotive receives the slag, thereby improving the excavation efficiency. At the same time, the rotating motor 3 can make the corresponding flip plate 22 disconnect from the adjacent flip plate 22, flip the slag falling on the flip plate 22 and put it into the corresponding flip bucket, and make the flip plate 22 unload the corresponding bucket without interfering with the work of the unloading equipment.

[0033] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
