[0051] Embodiment 1

[0052] As Figure 1 and Figure 2 shown, the present invention provides an obstacle removal device that can be used as an end plow. The obstacle removal device includes:

[0053] A main plow 3 and a lifting drive member 2. The lower end of the lifting drive member 2 is connected to the main plow 3, and the upper end of the lifting drive member 2 is used to connect to a railway vehicle. A rail groove 4 is provided at the lower end of the main plow 3, and a rail cleaning member 16 for contacting the railway track is arranged in the rail groove 4.

[0054] Specifically, the lifting drive member 2 can be a hydraulic drive member or a pneumatic drive member. When the obstacle removal device is used to remove obstacles, the lifting drive member 2 will drive the main plow 3 to rise. During the driving process of the railway vehicle, obstacles on the railway track can be removed. When pre-shaping the coarse gravel or crushed stones laid under and on both sides of the railway track, the lifting drive member 2 will drive the main plow 3 to descend. Furthermore, the track groove 4 will drop to the railway track. During the driving process of the railway vehicle, the coarse gravel or crushed stones can be pre-shaped. Thus, the obstacle removal device can complete two functions, saving the space of the railway vehicle, saving costs, and also saving labor during operation;

[0055] The track cleaning member 16 can be a rubber baffle or a rubber brush for cleaning the railway track.

[0056] In this embodiment, it further includes:

[0057] Two wing plows 5, the two wing plows 5 are respectively rotatably connected to both ends of the main plow 3. A wing plow locking assembly 6 is provided between the wing plows 5 and the main plow 3. When the wing plows 5 rotate relative to the main plow 3 to the bent position or the unfolded position, the wing plow locking assembly 6 can limit the rotation of the wing plows 5.

[0058] Specifically, when the obstacle removal device is used to remove obstacles, the two wing plows 5 rotate relative to the main plow 3 to the bent position. When pre-shaping the coarse gravel or crushed stones laid under and on both sides of the railway track, since the width of a single main plow 3 is generally only 2500 mm, in order to expand the pre-shaping range, the two wing plows 5 can be rotated relative to the main plow 3 to the unfolded position. At this time, the shaping width formed by the main plow 3 and the two wing plows 5 will reach 3280 mm, and thus the coarse gravel or crushed stones can be pre-shaped in a larger range, meeting the practical requirements.

[0059] In this embodiment, the two wing plows 5 can be controlled by cylinders to rotate relative to the main plow 3 to the bent position or the unfolded position.

[0060] Specifically, manual operation is not required, saving the physical strength of workers.

[0061] In this embodiment, it further includes:

[0062] A support seat 7, the support seat 7 is fixedly connected to the back of the main plow 3, and the lower end of the lifting drive member 2 is connected to the support seat 7;

[0063] Two guiding components 8, the two guiding components 8 are arranged on both sides of the lifting drive member 2. The upper ends of the guiding components 8 are used to be fixedly connected to the railway vehicle, and the lower ends of the guiding components 8 are fixedly connected to the support seat 7.

[0064] Specifically, when the lifting drive member 2 drives the main plow 3 to rise or fall, the two guiding components 8 are located on both sides of the lifting drive member 2 to play a guiding role, improving the stability of the main plow 3 when rising or falling.

[0065] In this embodiment, the guiding assembly includes a guiding end 81 and a housing end 82 slidably sleeved outside the guiding end 81; it further includes:

[0066] Two locking assemblies 9, the two locking assemblies 9 are respectively arranged on the two guiding assemblies 8, and the locking assembly 9 is used to limit the sliding of the guiding end 81 of the guiding assembly 8 relative to the housing end 82.

[0067] As Figure 3 shown, in this embodiment, the wing plow locking assembly 6 includes:

[0068] At least one first support arm 61, one end of the first support arm 61 is fixedly connected to the back of the main plow 3, and the other end of the first support arm 61 is fixedly connected with a first insertion cylinder 62;

[0069] At least one second support arm 63, one end of the second support arm 63 is fixedly connected to the back of the wing plow 5, the other end of the second support arm 63 is fixedly connected with a second insertion cylinder 64, a jack 65 is arranged on the second support arm 61, and the first support arm 61 and the second support arm 63 are arranged in a staggered manner;

[0070] An insertion rod 66, when the wing plow 5 rotates relative to the main plow 3 to the bent position, the vertical center line of the jack 65 coincides with the vertical center line of the first insertion cylinder 62, and the insertion rod 66 can be inserted into the jack 65 and the first insertion cylinder 62. When the wing plow 5 rotates relative to the main plow 3 to the unfolded position, the vertical center line of the second insertion cylinder 64 coincides with the vertical center line of the first insertion cylinder 62, and the insertion rod 66 can be inserted into the first insertion cylinder 62 and the second insertion cylinder 64.

[0071] Specifically, when the wing plow 5 rotates relative to the main plow 3 to the bent position, the insertion rod 66 is inserted into the jack 65 and the first insertion cylinder 62, which can limit the rotation of the wing plow 5. When the wing plow 5 rotates relative to the main plow 3 to the unfolded position, the insertion rod 66 is inserted into the first insertion cylinder 62 and the second insertion cylinder 64, which is also to limit the rotation of the wing plow 5. Furthermore, when the wing plow 5 is in the bent position or the unfolded position, the wing plow 5 can be fixed to prevent the wing plow 5 from rotating uncontrollably.

[0072] As Figure 8 shown, in this embodiment, both the housing end 82 and the guiding end 81 are rectangular tubular. The upper end of the housing end 82 is used to be fixedly connected to a railway vehicle, the lower end of the guiding end 81 is fixedly connected to the support seat 7, and a clearance adjustment assembly 14 is respectively arranged around the lower end of the housing end 82. The clearance adjustment assembly 14 includes:

[0073] A groove block 141, adjustment holes are arranged at both ends inside the groove block 141;

[0074] Adjustment shaft 142, both ends of the adjustment shaft 142 are respectively inserted into two adjustment holes, and there is an adjustment space between each end of the adjustment shaft 142 and the mating adjustment hole;

[0075] Adjustment wheel 143, the adjustment wheel 143 is arranged in the groove block 141 and rotatably connected to the adjustment shaft 142, and the adjustment wheel 143 can be in rolling connection with the guiding end 81;

[0076] One side of the groove block 141 away from the guiding end 81 is provided with a threaded hole communicating with the adjustment hole, the threaded hole is threadedly connected with a bolt 144, and one end of the bolt 144 can be screwed into the corresponding adjustment hole and abutted against one end of the adjustment shaft 142.

[0077] Specifically, when the guiding end 81 slides smoothly within the housing end 82, the two bolts 144 can be screwed to adjust the positions of both ends of the adjustment shaft 142 respectively located in the two adjustment holes. Furthermore, the adjustment wheel 143 can push the guiding end 81 relative to the housing end 82 to adjust the position of the guiding end 81 within the housing end 82. Since a clearance adjustment assembly 14 is respectively arranged around the lower end of the housing end 82, the four clearance adjustment assemblies 14 can be adjusted to prevent the guiding end 81 from being clamped tightly within the housing end 82 and ensure that the guiding end 81 slides smoothly within the housing end 82.

[0078] In this embodiment, a nut is threadedly connected to the bolt 144.

[0079] After the bolt 144 is screwed to the adjustment position, a double-nut lock is formed with a nut and the threaded hole above the groove block 141 to prevent the bolt 144 from falling off or changing its position during use, which may affect the clearance between the guiding end 81 and the housing end 82.

[0080] As Figure 5 、 Figure 6 and Figure 7 shown, in this embodiment, the locking assembly 9 includes:

[0081] A slot 96 provided on the guiding end 81 and a jack 97 provided on the housing end 82;

[0082] A stop block 91, the stop block 91 is fixedly connected to the outside of the housing end 82, a sliding hole 98 is provided inside the stop block 91, the center line of the sliding hole 98 coincides with that of the jack 97, and a first gear slot 93 and a second gear slot 94 communicating with the sliding hole 98 are provided on the stop block 91;

[0083] A locking pin 92, one end of the locking pin 92 is slidably connected in the sliding hole 98, and a stop pin 95 is fixedly connected to the locking pin 92 near the guiding end 81;

[0084] Wherein, when the main plow 3 is lifted, the center lines of the slot 96 and the jack 97 coincide. When one end of the locking pin 92 is inserted into the slot 96, the stop pin 95 can be driven by the rotation of the locking pin 92 to be engaged into the first gear slot 93. When one end of the locking pin 92 is pulled out of the slot 96, the stop pin 95 can be driven by the rotation of the locking pin 92 to be engaged into the second gear slot 94.

[0085] Specifically, when the lifting drive member 2 drives the main plow 3 to be lifted for obstacle removal, in order to improve the stability of the main plow 3, one end of the locking pin 92 is inserted into the slot 96 to limit the sliding of the guiding end 81, so that the guiding end 81 is stable within the housing end 82. Furthermore, the stability of the main plow 3 is maintained. At the same time, the two guiding ends 81 also support the main plow 3. When the main plow 3 is in the lifted state for a long time, the load borne by the lifting drive member 2 will be dispersed to the two guiding ends 81, which plays a protective role for the lifting drive member 2 and extends the service life of the lifting drive member 2. In order to prevent the locking pin 92 from disengaging from the slot 96, the locking pin 92 can be rotated so that the stop pin 95 thereon is engaged into the first gear slot 93, thereby being able to limit the locking pin 92 from sliding within the sliding hole 98. When the lifting drive member 2 drives the main plow 3 to descend, the locking pin 92 can be pulled out of the slot 96. In order to prevent the locking pin 92 from being accidentally inserted into the interior of the housing end 82, the locking pin 92 can be rotated so that the stop pin 95 thereon is engaged into the second gear slot 94.

[0086] In this embodiment, the stop block 91 is fixedly connected to the railway vehicle.

[0087] In this embodiment, a groove seat 15 is provided on the railway vehicle and at a position far from the stop block 91, and the position of the locking pin 92 far from the stop block 91 is slidably connected within the groove seat 15.

[0088] Specifically, it plays a supporting role for the position of the locking pin 92 far from the stop block 91.

[0089] In this embodiment, the locking pin 92 can be controlled by a cylinder to be locked into or pulled out of the slot 96.

[0090] Specifically, manual operation by workers is not required, saving the physical strength of the workers.

[0091] As Figure 4 shown, in this embodiment, it further includes:

[0092] Two main wear plates 10, the two main wear plates 10 are respectively arranged on both sides of the pushing surface of the main plow 3, and the main wear plates 10 are also provided with track grooves 4, which are matched with the track grooves on the main plow 3;

[0093] Two auxiliary wear plates 11, the two auxiliary wear plates 11 are respectively arranged on the pushing surfaces of the two wing plows 5.

[0094] Specifically, the main wear plate 10 and the auxiliary wear plate 11 can improve the service life of the main plow 3 and the wing plow 5.

[0095] Preferably, at least two first threaded holes are provided on the main wear plate 10, and at least two first oblong holes are provided on the main plow 3. The first bolt is threadedly connected to the first threaded hole and passes through the first oblong hole to be connected to the first nut;

[0096] At least two second threaded holes are provided on the auxiliary wear plate 11, and at least two second oblong holes are provided on the wing plow 5. The second bolt is threadedly connected to the second threaded hole and passes through the second oblong hole to be connected to the second nut;

[0097] Specifically, the height of the main wear plate 10 can be adjusted through the first oblong hole, and the height of the auxiliary wear plate 11 can be adjusted through the second oblong hole. When the main plow 3 is in the raised state, the height from the bottom ends of the main wear plate 10 and the auxiliary wear plate 11 to the rail surface of the railway track can be adjusted within the range of 75 mm - 120 mm. When the main plow 3 is in the lowered state, the bottom ends of the main wear plate 10 and the auxiliary wear plate 11 can be lowered below the rail surface of the railway track and be 110 mm away from the rail surface. When the worn main wear plate 10 and auxiliary wear plate 11 after working for a period of time can be replaced, which is very convenient, protecting the main plow 3 and the wing plow 5 of the device from wear and extending the service life of the device.

[0102] Specifically, when the lifting driving member 2 fails and cannot lift the main plow 3 to the position for removing obstacles, one ends of the two chain hoists can be respectively fixed in the two second seat holes, and then the other ends of the two chain hoists are respectively passed through the two first seat holes. When the other ends of the two chain hoists are pulled, the support seat 7 can be driven to rise, so that the main plow 3 can be lifted, thereby realizing emergency lifting.

[0103] Embodiment 2

[0104] A railway vehicle includes: an obstacle removal device that can be used as an end plow;

[0105] The upper end of the lifting drive member 2 is connected to the train end frame 1 of the railway vehicle.

[0106] Specifically, the railway vehicle can be a ballast regulating and profiling vehicle, a tamping vehicle, a ballast cleaning vehicle, etc.

[0107] In summary, the present invention provides a railway vehicle. When in operation, the obstacle removal device that can be used as an end plow is utilized. Taking one use as an example: when the obstacle removal device is used to remove obstacles, the lifting drive member 2 will drive the main plow 3 to be lifted. At the same time, the two guiding components 8 are located on both sides of the lifting drive member 2 to play a guiding role, improving the stability when the main plow 3 is lifted. In order to further improve the stability, one end of the locking pin 92 is inserted into the slot 96 to limit the sliding of the guiding end 81, so that the guiding end 81 is stable within the housing end 82. In order to prevent the locking pin 92 from disengaging from the slot 96, the locking pin 92 can be rotated so that the stop pin 95 thereon is engaged in the first gear slot 93, thereby being able to limit the locking pin 92 from sliding within the sliding hole 98. At this time, when the railway vehicle is traveling, the obstacles on the railway track can be removed. When pre-shaping the coarse gravel or crushed stones laid under and on both sides of the railway track, in order to expand the pre-shaping range, the two wing plows 5 can be rotated relative to the main plow 3 to the unfolded position. At this time, the shaping width formed by the main plow 3 and the two wing plows 5 can pre-shape the coarse gravel or crushed stones in a larger range. Then, by driving the main plow 3 to descend through the lifting drive member 2, furthermore, the track groove will drop to the railway track. When the railway vehicle is traveling, the coarse gravel or crushed stones can be pre-shaped. Thus, the two functions of the obstacle removal device can be switched conveniently and quickly, saving the space of the railway vehicle, saving costs, and also saving labor during operation.

[0108] The various embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
