Description

Technical Field

[0001] The utility model belongs to the technical field of railway ballast cleaning, and particularly relates to a ballast cleaning device capable of operating on a curve. Background Technique

[0002] With the development of rail transit infrastructure construction, the workload of ballast track construction and daily maintenance is large. After the construction of a new line or screening and backfilling, the ballast in the ballast bed often appears unevenly piled up, and sometimes some ballast splashes onto the sleeper surface or other places. To ensure the safety of train operation, it is necessary to level the ballast in the ballast bed and clean the ballast that has splashed onto the sleeper surface or other places. In this process, a ballast cleaning device is required.

[0003] In the prior art, a railway ballast cleaning device is disclosed. For example, the patent with the publication number CN101864706B discloses a multi-functional railway ballast cleaning device, including a vehicle body, a cleaning and washing system, and a conveying system. The conveying system includes a ballast guiding mechanism, a transverse conveying mechanism, and a longitudinal conveying mechanism; the ballast guiding mechanism includes an upper ballast inclined plate and an upper ballast baffle. Since a conveying system and a ballast storage bin are arranged on the vehicle body, operations such as ballast cleaning and ballast storage can be continuously completed, the ballast on the railway sleeper can be cleaned, and the cleaned ballast can be thrown to the side slope of the railway line; at the same time, due to the arrangement of the ballast guiding mechanism, the mutual conversion between the ballast storage operation and the ballast throwing operation can be reliably realized. The whole device has the advantages of simple structure, flexible conversion, convenient operation, and reliable operation.

[0004] It is undeniable that the multi-functional railway ballast cleaning device disclosed in this patent can indeed achieve the above effects. Of course, the ballast in the ballast bed can be leveled and the ballast splashed onto the sleeper surface can be cleaned by using this device. However, it still has certain deficiencies: the rear end of the brush cover is hinged to the brush cover seat fixed on the vehicle body, and the position near the front end is hinged to the hydraulic cylinder. By means of the telescopic movement of the hydraulic cylinder, the brush cover can be driven to rotate around the brush cover seat as the central axis, so that the rotary brush approaches or moves away from the sleeper, and the positions of components such as the brush cover and the rotary brush are fixed to realize the switching between the operating state and the traveling state. However, in the actual operation process, when relying solely on the hydraulic cylinder to position components such as the brush cover and the rotary brush, the hydraulic cylinder needs to bear the gravity of multiple components such as the brush cover and the rotary brush, and is prone to damage, which is not conducive to the smooth development of railway ballast cleaning work. In addition, the multi-functional railway ballast cleaning device is not convenient for curve operation.

[0005] The information disclosed in this background technical section is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of implication that this information constitutes the prior art already known to those of ordinary skill in the art.

[0032] Embodiment

[0033] Refer to the attached Figures 1-4 , a ballast cleaning device capable of curvilinear operation, comprising:

[0034] Vehicle body 1;

[0035] Cleaning mechanism 2, the cleaning mechanism 2 includes a brush cover 21 and a cleaning member 22 arranged in the brush cover 21; wherein, the rear end of the top of the brush cover 21 is hinged to the bottom of the vehicle body 1, and the top of the front end is fixed with a limit ear 211; in this embodiment, the specific structure of the cleaning member 22 is: the cleaning member 22 includes a rotating shaft 221 arranged in the brush cover 21 and penetrating through both ends of the brush cover 21 and rotatably connected to the brush cover 21, a plurality of cleaning rods 222 fixed on the rotating shaft 221, and a cleaning drive motor 223 fixed outside the brush cover 21 and connected to the rotating shaft 221; wherein, the bottom of the brush cover 21 is open, and when the cleaning rod 222 rotates to the bottom of the brush cover 21, the outer end of the cleaning rod 222 extends out from the bottom opening of the brush cover 21;

[0036] Lifting oil cylinder 3, the telescopic end of the lifting oil cylinder 3 is hinged to the middle position of the top of the brush cover 21, and the other end is hinged to the bottom of the vehicle body 1; specifically, a connection seat 212 corresponding to the lifting oil cylinder 21 is fixed at the middle position of the top of the brush cover 21, and the telescopic end of the lifting oil cylinder 3 is hinged to the connection seat 212 through a spherical plain bearing; it should be added here that the spherical plain bearing is fixed to the telescopic end of the lifting oil cylinder 3;

[0037] Limit seat 4, the limit seat 4 is fixed to the bottom of the vehicle body 1; when the telescopic end of the lifting oil cylinder 3 retracts, the limit ear 211 corresponds to the position of the limit seat 4, and a cylindrical pin penetrates through the limit ear 211 and the limit seat 4 to fix the limit ear 211 and the limit seat 4, so as to realize the fixation of the brush cover 21; it is not difficult to understand here that through holes corresponding to the cylindrical pin are provided on the limit ear 211 and the limit seat 4; in addition, the cylindrical pin can be fixed to the limit seat 4 through a rope for convenient use;

[0038] In addition, in this embodiment, at least two chains 213 are symmetrically fixed to the top of the brush cover 21, and a fixing bolt 214 is fixed to the end of the chain 213; a fixing seat 11 corresponding to the fixing bolt 214 is fixed to the bottom of the vehicle body 1; after the fixing bolt 214 passes through the fixing seat 11, it is threadedly connected with a fixing nut 215.

[0039] In this embodiment, in order to realize the curve operation of the ballast cleaning device, a cross beam 12 is fixed to the bottom of the vehicle body 1, and two "C"-shaped chutes 13 extending along its length are spaced and fixed to the bottom of the cross beam 12. The opening of the chute 13 is located at the bottom. A sliding plate 14 that is slidably and guidingly matched with the chute 13 is arranged in the chute 13. An articulated arm 15 is fixed to the sliding plate 14. The lower end of the articulated arm 15 vertically extends out from the bottom opening of the chute and is hinged to the rear end of the top of the brush cover 21 through a spherical plain bearing. Specifically: an articulated seat 216 corresponding to the articulated arm 15 is fixed to the rear end of the top of the brush cover 21, and the lower end of the articulated arm 15 is hinged to the articulated seat 216 through a spherical plain bearing. It should be supplemented here that the spherical plain bearing is fixed to the lower end of the articulated arm 15; a horizontal traversing oil cylinder 16 is arranged at one end of the cross beam 12; the telescopic end of the traversing oil cylinder 16 is hinged to the sliding plate 14 and the other end is fixed to the cross beam 12. Specifically: a connecting plate 17 is fixed to one end of the sliding plate 14 close to the traversing oil cylinder 16, and the telescopic end of the traversing oil cylinder 16 is hinged to the connecting plate 17.

[0040] During the cleaning operation, the lifting oil cylinder 3 is started. The telescopic end of the lifting oil cylinder 3 extends out and pushes the brush cover 21 through the connecting seat 212. The brush cover 21 rotates around the articulated seat 216. When the cleaning rod 222 of the cleaning member 22 approaches the sleeper, the lifting oil cylinder 3 is locked. At the same time, the chain 213 is fully extended and generates a pulling force on the brush cover 21. In this way, the chain 213 can assist the lifting oil cylinder 3 to fix the brush cover 21 during the cleaning operation. Then the cleaning drive motor 223 is started. The cleaning drive motor 223 drives the rotating shaft 221 to rotate. The rotating shaft 221 drives the cleaning rod 222 to rotate. The rotating cleaning rod 222 contacts the sleeper and the ballast on the sleeper surface, and pushes the part of the ballast into the ballast bed. It can effectively ensure that the sleeper on the track is clean without ballast. At the same time, it can also level the accumulated ballast in the ballast bed to avoid the accumulation of ballast, and can effectively improve the safety and stability of train operation.

[0041] When the cleaning is completed and the vehicle is put away, the lifting oil cylinder 3 is started. The telescopic end of the lifting oil cylinder 3 retracts and drives the brush cover 21 through the connecting seat 212. The brush cover 21 rotates around the articulated seat 216 and moves away from the sleeper; when the telescopic end of the lifting oil cylinder 3 retracts to the initial state, the limit ear 211 corresponds to the position of the limit seat 4. A cylindrical pin penetrates through the limit ear 211 and the limit seat 4 to fix the limit ear 211 and the limit seat 4, so as to realize the fixation of the brush cover 21. In this way, with the help of the limit ear 211 and the limit seat 4, the lifting oil cylinder 3 can be assisted to fix the brush cover 21 in the vehicle-put-away state.

[0042] When a curve cleaning operation is to be carried out, the transverse movement oil cylinder 16 is started. When the telescopic end of the transverse movement oil cylinder 16 extends, a thrust is generated on the sliding plate 14 through the connecting plate 17. Under the action of this thrust, the sliding plate 14 slides in the sliding groove 13. When the sliding plate 14 slides, it drives the articulated arm 14 to move, and the articulated arm 14 drives the rear end of the brush cover 21 to move, thereby realizing a slight deflection of the brush cover 21. Then, the lifting oil cylinder 3 is started for the cleaning operation, and the curve cleaning operation can be realized. It should be supplemented and explained here that since both the lifting oil cylinder 3 and the articulated arm 14 are hinged to the brush cover through spherical plain bearings, when the transverse movement oil cylinder 16 is started, a slight deflection of the brush cover 21 can be realized and there will be no interference. In addition, it should be supplemented and explained that when carrying out the curve operation, in order to prevent the chain 213 from interfering, the fixing nut 215 on the fixing bolt 214 can be screwed loose for a certain distance to make the chain 213 loose.

[0043] The foregoing description of the specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the present invention to the precise forms disclosed, and obviously, many changes and variations are possible in light of the above teaching.
