Description

Technical Field

[0001] The present application relates to the technical field of bulk material transportation, and in particular to a mobile train fast unloading machine. Background Art

[0002] Unloading of bulk materials from trains is a complex process involving a variety of equipment and processes. The main purpose is to efficiently and safely unload bulk goods from train cars and transfer them to designated locations. Common ways of unloading bulk materials from trains include: unloading by car tippers, screw unloaders, chain bucket unloaders, bottom-opening dump trucks, and automatic reclaimers. Among them, a car tipper is a device specifically used to flip railway open cars to achieve automatic unloading of bulk materials. The car tipper rotates or tilts the car so that bulk materials (such as coal, ore, etc.) automatically dump into the receiving hopper or conveyor belt below by gravity. This method has the advantages of fast unloading speed and high degree of automation, and is suitable for the rapid unloading of large quantities of bulk materials.

[0003] The steps of unloading a car with a car tipper mainly include train arrival and positioning, unloading operations, and empty car towing. The arrival and positioning of the train requires the use of a traction locomotive to tow the vehicle to the unloading position of the car tipper. During the unloading operation, the car to be unloaded needs to be manually uncoupled from other cars, and then the car tipper starts to rotate and performs the unloading operation. Since the position of the car tipper is fixed, a vehicle needs to be towed each time the car tipping and unloading is performed, resulting in low efficiency of unloading. In order to improve the unloading efficiency, users usually arrange multiple car tippers on an unloading line, and multiple car tippers work synchronously, which increases the cost of the unloading equipment. At the same time, when the existing train car tippers are in use, the vehicle to be flipped needs to be towed onto the tipping platform, and the tipping platform needs to be flipped with the vehicle each time, which increases the energy consumption when the car tipper is in use. Summary of the invention

[0004] The present application provides a mobile train fast unloading machine, which has high flexibility and can be moved to any unloading position according to usage requirements. When unloading, only the train carriages need to be flipped individually, and the energy consumption during unloading is low, which can effectively solve the problems in the background technology.

The carriage 9 rotates under the drive of the flipping mechanism, and the materials inside the carriage 9 fall into the receiving hopper 3. After the material receiving is completed, the mobile frame 2 retracts the receiving hopper 3, and the receiving hopper 3 is then flipped over to dump the materials inside it into the receiving seam of the silo.

[0029] When the material is piled up in the silo, a strip material gap is opened along the train track 8, and a conveyor belt is installed inside the strip material gap. The conveyor belt is used to transport the material falling into the strip material gap to the silo.

[0030] When open-air stacking is adopted, a sunken stacking area is dug on one side or both sides of the railway track 8, and the materials dumped by the receiving hopper 3 fall directly into the dumping area.

The positioning rollers 12 can not only realize the positioning of the cylindrical gyro 15, but also have a good load-bearing effect.

[0043] Furthermore, the clamping block 24 includes a clamping plate 241 , and a sinking step 242 is provided at the end of the outer side surface of the clamping plate 241 .

[0044] Specifically, the sunken step 242 is used to engage the upper or lower edge of the carriage 9 to prevent the carriage 9 from being displaced during the overturning and unloading process.

[0045] Furthermore, a follower wheel is installed on the lower surface of the follower bracket 10 .

[0046] Specifically, the setting of the follower wheel can be used to support the receiving hopper 3 and ensure that the receiving hopper 3 can move together with the active traveling wheel 18.

[0051] Specifically, the load-bearing roller set 1 is rollingly connected to the inner side surface of the U-shaped slide groove 19, and when the moving frame 2 slides along the inner side surface of the U-shaped slide groove 19, the friction force is small.

[0052] Furthermore, a linear motor is installed on the follower bracket 10 , and a slide of the linear motor is connected to the moving frame 2 .

[0053] Specifically, the linear motor is used to control the reciprocating motion of the moving frame 2 along the U-shaped slide groove 19 .

[0054] During use: after the train loaded with bulk materials arrives at the unloading area, the connection between the carriages 9 is loosened, and the cylindrical gyro 15 is driven to move by the active traveling wheel 18. When the carriage 9 to be unloaded is completely located inside the cylindrical gyro 15, the hydraulic telescopic rod 21 and the hydraulic telescopic rod 3 23 are synchronously extended to clamp the clamping block 24 at the edge of the carriage 9.

[0055] Start the hydraulic support arm 10, the hydraulic support arm 10 extends to lift the carriage 9, and then the linear motor sends the receiving hopper 3 to the bottom of the carriage 9, and start the motor 14. The motor 14 drives the cylindrical gyro 15 to rotate through the gear transmission mechanism, and the cylindrical gyro 15 drives the carriage 9 to rotate, and the material in the carriage 9 falls into the receiving hopper 3. After the material is received, the linear motor withdraws the receiving hopper 3, and then the hydraulic telescopic rod 4 extends to push the receiving hopper 3 to flip, and the material inside the receiving hopper 3 falls into the material trough.

[0056] After the carriage 9 is unloaded, the cylindrical gyro 15 drives the carriage 9 to rotate back to its original position, and then the hydraulic support arm 10 contracts to put the carriage 9 back on the train track 8, and the fast unloading machine moves to another adjacent carriage and unloads it using the same method.

[0057] It is worth noting that the hydraulic telescopic rod 1 4, the hydraulic support arm 7, the hydraulic telescopic rod 2 21 and the hydraulic telescopic rod 3 23 are connected to an external hydraulic station. The external hydraulic station controls the extension and retraction of the hydraulic telescopic rod 1 4, the hydraulic support arm 7, the hydraulic telescopic rod 2 21 and the hydraulic telescopic rod 3 23.
