Description

Technical Field

[0001] The invention relates to loading equipment, in particular to rapid loading equipment for railway transportation, and belongs to the technical field of railway freight loading. Background Art

[0002] Railway transportation is a mode of transportation that uses railway trains to transport passengers and goods. It plays an important role in the social material production process. It has the characteristics of large transportation volume, fast speed and low cost, and is suitable for long-distance transportation of bulky and heavy goods. This makes railways one of the resource-based and environmentally friendly modes of transportation, and plays a role as a major artery for the development of the national economy.

[0003] Loading equipment is one of the important equipment in railway transportation operations. It is mainly used to load bulk goods into train carriages; especially in coal transportation operations, it can quickly and effectively load bulk coal into train carriages for subsequent railway transportation.

[0004] The Chinese patent name is "A combined application system of a train loading building and a car transfer platform" (patent number is ZL201910384014.0), which discloses a combination technology of a loading building and a car transfer platform, including a train loading building, a car transfer platform, an empty car positioning vehicle and a heavy car positioning vehicle. The bottom of the car transfer platform is provided with a running device and the upper part is provided with a car transfer platform track compatible with the railway track, so as to move the empty car body horizontally to the heavy car railway line; the empty car positioning vehicle pulls the empty car train set on the empty car railway line to the front of the car transfer platform and pulls several empty car bodies after the detraining to the car transfer platform track on the car transfer platform; the heavy car positioning vehicle pushes the empty car body on the car transfer platform to the loading position under the train loading building of the heavy car railway line. Although the loading building can effectively solve the problem that the train loading building cannot be used for loading when the length of the railway loading line does not meet the requirements of twice the length of the train or the length of the straight section of the railway line, and can retain the characteristics of the loading building with good environmental performance and accurate measurement; however, its overall structure is too large, similar to the traditional loading building, and the construction and use costs are relatively high; and before loading, it is necessary to use conveying or lifting equipment to pre-store the materials to be loaded in a buffer bin at a high place, so as to use the gravity of the materials themselves to complete the subsequent loading operations, and the operation method is relatively inconvenient.

[0050] The compression locking mechanism 502 is used to cooperate with the power of the split hydraulic drive mechanism 4 to unlock or lock the two end covers 303.

The motor frame 201 is provided to increase the installation stability of the reduction motor 202.

[0054] In one embodiment, the plurality of split hydraulic drive mechanisms 4 each include a plurality of oil storage barrels 401, a plurality of piston plates 402, a plurality of pressure bearing rods 403, a plurality of springs 404, a plurality of negative pressure resistant metal hoses 405, two lower brackets 406 and two hydraulic cylinders 407;

[0055] Among them, a number of oil storage cylinders 401 are respectively fixedly connected to the middle of the outer side walls of a number of material buckets 302, a number of piston plates 402 are respectively slidably connected to the inner side walls of a number of oil storage cylinders 401, a number of pressure rods 403 are respectively fixedly connected to one end of a number of piston plates 402 and extend to the outside of the oil storage cylinders 401, a number of springs 404 are respectively fixedly connected between a number of piston plates 402 and the inner side walls of a number of oil storage cylinders 401, one end of a number of negative pressure resistant metal hoses 405 are respectively connected to the outer side walls of a number of oil storage cylinders 401, an oil seal 65 is fixedly connected to one side of the inner side wall of the oil storage cylinder 401, the outer side wall of the pressure rod 403 is slidably connected to the inner side wall of the oil seal 65, and the outer side of the number of negative pressure resistant metal hoses 405 is sleeved with a limiting ear 64, and the limiting ear 64 is fixedly connected to the outer side of the material bucket 302;

[0056] The two lower brackets 406 are respectively fixedly connected to the inner side walls of the two annular brackets 102 , and the two hydraulic cylinders 407 are respectively installed on one side of the two lower brackets 406 . The output shaft of the hydraulic cylinder 407 is correspondingly arranged to one end of the pressure rod 403 .

[0057] The piston rod of the hydraulic cylinder 407 is used to squeeze one end of the pressure rod 403, so that the pressure rod 403 drives the piston plate 402 to move. The moving piston plate 402 forms a negative pressure on one side of the oil storage cylinder 401 and drives the spring 404 to be compressed.

[0058] The oil seal 65 is provided to increase the sealing between the pressure-bearing rod 403 and the oil storage cylinder 401 to prevent leakage of hydraulic oil, and the limiting ear 64 is provided to limit the negative pressure-resistant metal hose 405 on the outside of the material hopper 302.

[0059] In one embodiment, the plurality of reset force storage mechanisms 501 each include a storage slot 511 , a connecting shaft 512 , and a torsion spring 513 ;

[0060] Among them, the storage groove 511 is opened on one side of the material hopper 302, the connecting shaft 512 passes through the inner wall of the material hopper 302 and is fixedly connected to the inner wall of the end cover 303, and the torsion spring 513 is fixedly connected between the outer wall of the connecting shaft 512 and the inner wall of the storage groove 511.

[0061] The end cover 303 drives the connecting shaft 512 to rotate under the action of pressure, and the rotating connecting shaft 512 drives the torsion spring 513 to twist.

[0062] In one embodiment, the plurality of compression locking mechanisms 502 each include a one-way hydraulic cylinder 521, an insert block 522, and two socket ears 523;

[0063] Among them, the one-way hydraulic cylinder 521 is installed at the bottom of the end cover 303, the end of the negative pressure resistant metal hose 405 away from the oil storage cylinder 401 is connected to the input end of the one-way hydraulic cylinder 521, the plug block 522 is fixedly connected to the output shaft of the one-way hydraulic cylinder 521, the two socket ears 523 are respectively fixedly connected to the bottom of the two end covers 303, and the outer wall of the plug block 522 is slidably connected to the inner wall of the two socket ears 523.

[0064] Under the action of negative pressure, the hydraulic oil in the one-way hydraulic cylinder 521 is sucked into the oil storage tube 401 through the negative pressure-resistant metal hose 405, so that its piston rod drives the plug block 522 to slide from between the two bell ears 523 to the inside of one bell ear 523, so as to unlock the two end covers 303. The contact surface between the plug block 522 and the bell ear 523 can also be set as a spherical surface to reduce the friction between the plug block 522 and the bell ear 523, thereby ensuring that the piston rod of the one-way hydraulic cylinder 521 can drive the plug block 522 to slide smoothly in the bell ear 523.

[0065] In one embodiment, an extension portion 61 is provided in the middle of the inner wall of the embedded base 101 , and a rail 62 is installed at the bottom of the inner wall of the extension portion 61 .

[0066] By utilizing the extension portion 61 in the embedded base 101 , an installation space is provided for the rail 62 .

[0067] When the present invention is working: first, the embedded base 101 is installed as a whole to the specified position by pre-embedded method according to actual needs, and then the rail 62 is laid in the extension part 61, so that the train box 63 can smoothly pass through the annular bracket 102 and the gear ring bracket 301 along the rail 62.

[0068] When the train box 63 moves between the two gear ring frames 301 and loading operations are required, the output shaft of the reduction motor 202 is used to drive the drive gear 203 to rotate, and the rotating drive gear 203 uses the tooth pattern to drive the two gear ring frames 301 to rotate synchronously, and the rotating gear ring frames 301 drive the material bucket 302 to move axially around the gear ring frames 301. When the material bucket 302 moves to the loading port 103, the material to be loaded can be put into the material bucket 302 for storage by using a near-ground conveyor or loader, and then the material bucket 302 is driven to continue to move by the rotating gear ring frame 301, so as to transfer the material bucket 302 filled with materials to the top of the train box 63, and in the process of transfer, the new material bucket 302 can be used to store the materials for subsequent continuous unloading.

[0069] When the material is transferred to the top of the train box 63, the piston rod of the hydraulic cylinder 407 squeezes one end of the pressure rod 403 so that the pressure rod 403 can be used to drive the piston plate 402 to move. The moving piston plate 402 forms a negative pressure on one side of the oil storage cylinder 401 and drives the spring 404 to be compressed. Then, the hydraulic oil in the one-way hydraulic cylinder 521 is sucked into the oil storage cylinder 401 through the negative pressure-resistant metal hose 405 under the action of negative pressure, so that the piston rod drives the plug 522 to slide from between the two socket ears 523 to the inside of one socket ear 523, so as to unlock the two end covers 303. Then, the connecting shaft 512 is driven to rotate under the action of pressure through the end cover 303, and the rotating connecting shaft 512 drives the torsion spring 513 to twist, so as to accumulate force while the end cover 303 opens the bottom of the material hopper 302. When the bottom of the material hopper 302 is opened, the material inside it falls directly into the interior of the train box 63 for storage under the action of gravity.

[0070] When the loading and unloading of materials in the material hopper 302 is completed, the end cover 303 is reset by using the twisted torsion spring 513 and the connecting shaft 512, so that the two socket ears 523 overlap again, and then the hydraulic cylinder 407 is started to reset its piston rod, and then the piston plate 402 is pushed to reset by the compressed spring 404, so that during the resetting process of the piston plate 402, the negative pressure-resistant metal hose 405 is used to inject hydraulic pressure into the inside of the one-way hydraulic cylinder 521, and the piston rod of the one-way hydraulic cylinder 521 drives the insert block 522 to be inserted between the two socket ears 523 to lock the end cover 303, so that the material hopper 302 as a whole can be reused to facilitate continuous loading operations in the train box 63.

[0071] The oil seal 65 is provided to increase the sealing between the pressure-bearing rod 403 and the oil storage cylinder 401 to prevent leakage of hydraulic oil, and the limiting ear 64 is provided to limit the negative pressure-resistant metal hose 405 on the outside of the material hopper 302.

[0072] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
