Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a silo weighing type train loader. Background Art

[0002] Train loaders are an essential piece of equipment in modern railway transport. They are primarily used to load bulk materials (such as coal and ore) from storage yards or warehouses into train carriages. By installing the rail-mounted train loader on dedicated tracks, the trains are arranged in a straight line, and the dedicated tracks align with the train tracks. By driving the rail-mounted train loader along the dedicated tracks, the carriages can be loaded with materials one by one.

[0003] Due to the different models of train carriages, for example, the loading vehicles are the national railway C64, C65, C70, C80 and other models. Therefore, the rail-mounted train loader not only needs to efficiently load various bulk materials from the yard or warehouse into the carriage, but also needs to ensure that the weight of the loaded bulk materials meets the weight standards of the carriage.

[0004] In order to facilitate loading, technicians have developed related train loading machines. For example, the utility model with authorization publication number CN201808947U involves a bulk material loading machine, including a trolley traveling mechanism, a main frame, a tail car, a rotating hopper, an arm system and a ground belt conveyor connected to the tail car. The main frame is connected to the trolley traveling mechanism, the tail car is connected to the main frame, the loading port of the tail car is connected to the ground belt conveyor, and the rotating hopper is located below the discharge port of the tail car; the rotating hopper includes a return hopper and a feeding hopper, the arm system is located below the outlet of the feeding hopper, the end of the arm system away from the feeding hopper is located above the car, and the ground belt conveyor is located below the outlet of the return hopper. During loading, the bulk materials in the yard are transported to the tail car through the ground belt conveyor, and then flow out from the tail car to the transfer hopper. At this time, the feed hopper sends the bulk materials to the boom system, and the boom system transports them to the carriage. The return hopper sends the bulk materials to the ground belt conveyor and transports them back to the yard. Until the loading is completed, the loader moves to the next carriage, and the fork bucket at the head transfers the materials directly to the next carriage.

[0005] However, in the actual loading process, when the loader does not need to load materials in the "prohibited loading area (i.e., broken car)", and the material flow rate needs to be accurately calculated when loading one or two cars before the last car, the use of the existing rail-type train loader will lead to inaccurate flow calculation, resulting in inaccurate loading data and possible spillage of materials into the "prohibited loading area", thereby causing problems such as large amount of returned materials. Utility Model Content

[0006] In order to improve the problem of inaccurate flow calculation and large amount of returned materials, the utility model provides a rail-type train loader with high weighing accuracy and low amount of returned materials.

[0007] The utility model provides a silo weighing type train loader, which adopts the following technical solutions:

[0008] A silo weighing train loader comprises a loading body and a buffer discharge mechanism; the buffer discharge mechanism comprises a traveling frame and a discharge assembly arranged on the traveling frame, wherein the traveling frame is framed in a carriage;

[0009] The discharge assembly includes a silo, an opening and closing part, and a weight measuring part. The silo is arranged through the traveling frame and is located above the carriage. The opening and closing part is arranged at the bottom end of the silo. A base is also provided on the silo. The base is provided with a first connecting block, and the traveling frame is provided with a second connecting block. The second connecting block is hinged to the first connecting block through the weight measuring part. An elastic part is also provided on the base, and the end of the elastic part away from the base is connected to the traveling frame.

[0010] Through the above technical solution, when the loading body moves and approaches the next car, the traveling frame is driven to move synchronously with the loading body to the corresponding car, and the loading body transports the material into the silo. At this time, the opening and closing parts are in the closed state, and the weight is weighed by the weight measuring part. The control module receives the detection data of the weight measuring part and subtracts the gross weight of the equipment. When the weight of the material reaches the preset weight of the car, the loading body stops transporting the material into the silo. When the loading body approaches the next car, that is, when the traveling frame reaches the next car, the opening and closing parts are driven to the open state, and the material falls into the car by gravity, so that the material can be accurately loaded into the car. At the same time, by moving the traveling frame back and forth in the car, the material can be discharged more evenly.

[0011] In summary, the materials are weighed while the equipment is moving to the next carriage, and loaded when the weighing is completed and the equipment reaches the carriage. This is beneficial to the overall continuous operation of the equipment and makes the loading more accurate, thereby reducing the return of materials.

[0012] Preferably, the loading body includes a travel control mechanism, a main frame arranged on the travel control mechanism, a loading tail car arranged on the main frame, a rotating hopper, and a retractable arm. The retractable arm is equipped with a belt conveyor, and the rotating hopper is connected and communicated with the discharge end of the loading tail car. The rotating hopper is located above the belt conveyor, and the end of the belt conveyor is located above the silo.

[0013] With the above technical solution, during operation, the travel control mechanism drives the main frame to move along the direction of the dedicated track and approach the carriage, while simultaneously driving the travel frame to the corresponding carriage. By conveying materials to the loading tail car, the materials of the loading tail car are sent from the discharge end to the transfer hopper. The materials in the transfer hopper fall into the belt conveyor by gravity, and are sent to the end of the belt conveyor. They fall into the silo by gravity, thus conveniently transporting the materials to the silo.

[0014] Preferably, the telescopic end of the telescopic arm is further provided with a guide hopper, the end of the belt conveyor extends into the guide hopper, the top of the guide hopper is closed, the bottom of the guide hopper is a lead-out part, and the lead-out part extends into the hopper.

[0015] Through the above technical solution, when the material reaches the end of the belt conveyor, the material is introduced into the hopper from the outlet part. The guidance of the guide hopper is conducive to guiding the material, preventing the material from flying, and reducing material loss during transportation.

[0016] Preferably, a material guide ramp for guiding the material to the outlet portion is further provided in the guide hopper.

[0017] Through the above technical solution, when the material is discharged from the end of the belt conveyor, according to the driving force of the belt conveyor to transport the material and the effect of the gravity of the material, the material will fall to the material guide ramp, and finally the material will be guided to the hopper through the material guide ramp. The guidance of the material guide ramp is conducive to increasing fluidity and reducing the accumulation and blockage of materials in the guide hopper.

[0018] Preferably, the walking frame is rotatably connected to a driving wheel, and the driving wheels are divided into two groups, and each group has no less than two driving wheels, and the two groups of driving wheels are respectively located on two opposite sides of the walking frame.

[0019] Through the above technical solution, the walking frame can be conveniently driven and supported by the driving wheels.

[0020] Preferably, the bottom end of the silo is contracted, and the bottom end of the silo contracts from top to bottom.

[0021] Through the above technical solution, the shape of the silo is conducive to guiding the material in the silo to flow out from the bottom.

[0022] Preferably, the opening and closing member is a jaw-type hopper door.

[0023] Through the above technical solution, the jaw bucket door has good sealing performance and can achieve very precise material discharge control, which is conducive to achieving accurate material discharge while reducing material loss.

[0024] Preferably, the weight measuring member is a pin-type weighing sensor.

[0025] Through the above technical solution, a pin-type weighing sensor is used to connect the force-bearing part with the sensor body, which can accurately sense the change of force and convert it into an electrical signal, which is conducive to reducing the impact of external interference, temperature changes or vibrations, thereby providing more stable and accurate weighing data.

[0026] Preferably, the silo is also provided with a silo wall vibrator.

[0027] Through the above technical solution, the high-frequency vibration generated by the silo wall vibrator can separate the materials attached to the silo wall, thereby avoiding material accumulation and blockage.

[0028] Preferably, a control module is also provided on the main frame, and the control module is electrically connected to the weight measuring part, the opening and closing part and the belt conveyor. A cable tray is also provided on one side of the silo, and the cable tray away from one end of the silo is connected to the main frame.

[0029] Through the above technical solution, when weighing, weighing is performed through the weight measuring piece, the control module receives the detection data of the weight measuring piece, and subtracts the gross weight of the equipment. At this time, the opening and closing piece is in a closed state, and the belt conveyor transports the material to the silo. The weight measuring piece detects in real time. When the weight of the material reaches the preset weight of the carriage, the control module stops the belt conveyor and drives the opening and closing piece to the open state, thereby combining with the control module for calculation to accurately load the material into the carriage.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] When the travel control mechanism drives the main frame to move along the direction of the dedicated track distribution and approaches the next car, the travel frame is synchronously moved to the corresponding car by driving the driving wheel to rotate. The material is transported to the loading tail car, and the material of the loading tail car is sent out of the transfer hopper from the discharge end. The material in the transfer hopper falls into the belt conveyor by gravity and is sent to the guide hopper through the belt conveyor. The material is guided into the silo by the guide hopper. At this time, the opening and closing parts are in the closed state, and weighing is performed by the weight measuring part. The control module receives the detection data of the weight measuring part and subtracts the gross weight of the equipment to realize real-time weighing.

[0032] When the weight of the material reaches the preset weight of the carriage, the belt conveyor stops conveying. When the travel control mechanism drives the main frame to align with the next carriage, that is, when the travel frame reaches the next carriage, the control module drives the opening and closing parts to the open state, and the material falls into the carriage by gravity, so it can be accurately loaded into the carriage. At the same time, by driving the driving wheel to rotate, the travel frame is driven to move back and forth in the carriage, so that the material unloading can be more uniform.

[0033] The material is weighed as the equipment moves to the next carriage, and loaded when the weighing is completed and the material reaches the carriage. This is beneficial to the overall continuous operation of the equipment and makes the loading more accurate, thereby reducing the work of returning materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is a combination of the appended examples of the present invention Figures 1 to 5 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] A silo weighing train loader, refer to Figure 1 , including a loading body 1 and a buffer discharge mechanism 2 connected to the loading body 1, wherein the loading body 1 is set on a dedicated track 3, and the loading body 1 is located on one side of the train, and the buffer discharge mechanism 2 is located at the train.

[0043] Specifically, refer to Figure 1 and Figure 2 The loading body 1 includes a travel control mechanism 11, a main frame 12 mounted on the travel control mechanism 11, a loading tail car 13 mounted on the main frame 12, a transfer hopper 14, and an arm mechanism. The travel control mechanism 11, the loading tail car 13, and the transfer hopper 14 are all well-established technologies in the prior art and will not be described in detail. The travel control mechanism 11 is mounted on the dedicated track 3 and drives the main frame 12 to move along the distribution direction of the dedicated track 3, thereby driving the main frame 12 to move along the distribution direction of the dedicated track 3 and approach each carriage 6.

[0044] Continue to refer to Figure 1 and Figure 2 In this embodiment, a ground belt conveyor 4 is connected to the feed end of the loading tail car 13, so that the material 5 is transported to the loading tail car 13 by the ground belt conveyor 4. The rotary hopper 14 is connected and communicated with the discharge end of the loading tail car 13. When the material 5 at the loading tail car 13 is sent out from the discharge end, the material 5 falls into the rotary hopper 14.

[0045] Reference Figure 2 and Figure 3 The boom mechanism includes a retractable boom 15 and a belt conveyor 16 mounted on the retractable boom 15. The retractable boom 15 is horizontally arranged, with its fixed end extending into and connected to the main frame 12. The retractable end of the retractable boom 15 retracts and extends horizontally, and is in an extended position above the buffer discharge mechanism 2. The hopper 14 is located above the belt conveyor 16, so that the material 5 in the hopper 14 falls into the belt conveyor 16 by gravity. The belt conveyor 16 is conventional technology and conveys the material 5 in the direction of the retractable boom 15's extension and contraction, with the end of the belt conveyor 16 located above the buffer discharge mechanism 2.

[0046] In addition, refer to Figure 2 and Figure 3The telescopic end of the telescopic arm 15 is also provided with a guide hopper 17. The guide hopper 17 is used to guide the material 5 at the end of the belt conveyor 16 to the buffer discharge mechanism 2. The end of the belt conveyor 16 extends into the guide hopper 17. The top of the guide hopper 17 is closed, and the bottom of the guide hopper 17 is a discharge portion 171, which extends into the buffer discharge mechanism 2. Therefore, when the material 5 reaches the end of the belt conveyor 16, the material 5 is introduced into the buffer discharge mechanism 2 through the discharge portion 171. The guidance of the guide hopper 17 helps guide the material 5, prevents the material 5 from flying, and reduces the loss of material 5 during transportation. A material guide ramp 18 is also provided in the guide hopper 17. The guide ramp 18 is used to guide the material 5 to the outlet portion 171. When the material 5 is discharged from the end of the belt conveyor 16, according to the driving force of the belt conveyor 16 to transport the material 5 and the gravity of the material 5, the material 5 will fall to the guide ramp 18. Finally, the material 5 is guided by the guide ramp 18 to the buffer discharge mechanism 2. The guidance of the guide ramp 18 is conducive to increasing fluidity and reducing the accumulation and blockage of the material 5 in the guide hopper 17.

[0047] During operation, the travel control mechanism 11 drives the main frame 12 to move along the direction of the dedicated track 3 and approach the carriage 6. The buffer discharge mechanism 2 is synchronously driven to the corresponding carriage 6. The material 5 is transported to the loading tail car 13 by the ground belt conveyor 4. The material 5 of the loading tail car 13 is sent out of the transfer hopper 14 from the discharge end. The material 5 in the transfer hopper 14 falls into the belt conveyor 16 by gravity and is sent to the guide hopper 17 by the belt conveyor 16. The guide hopper 17 guides the material 5 to the buffer discharge mechanism 2. Finally, the buffer discharge mechanism 2 controls the material 5 to be accurately discharged into the carriage 6, which can ensure the loading amount of the current carriage 6, thereby helping to reduce the work of returning materials.

[0048] Specifically, refer to Figure 4 The buffer discharge mechanism 2 includes a traveling assembly and a discharge assembly arranged on the traveling assembly. The traveling assembly includes a traveling frame 21 and a driving wheel 29 rotatably connected to the traveling frame 21.

[0049] Reference Figure 4 The running frame 21 is in an inverted U shape, with the closed end of the running frame 21 facing upward, and the carriage 6 is located within the open end of the running frame 21, that is, the running frame 21 is framed by the carriage 6, and the unloading assembly is located at the closed end of the running frame 21. The driving wheel 29 is rotatably connected to the running frame 21 and is close to the open end of the running frame 21. The driving wheel 29 is used to more smoothly drive the running frame 21 to move along the direction of train distribution. There are multiple driving wheels 29, and the multiple driving wheels 29 are divided into two groups, and each group has no less than two driving wheels 29. In this embodiment, there are four driving wheels 29, and the two groups of driving wheels 29 are respectively located on both sides of the running frame 21. The two groups of driving wheels 29 are opposite to each other in a direction perpendicular to the direction of train distribution, thereby conveniently driving and supporting the running frame 21.

[0050] During operation, the travel control mechanism 11 drives the main frame 12 to move along the direction of the dedicated track 3 and approach the carriage 6. At the same time, by driving the driving wheel 29 to rotate, the travel frame 21 is synchronously moved to the corresponding carriage 6. The material 5 is transported to the loading tail car 13 by the ground belt conveyor 4. The material 5 of the loading tail car 13 is sent out of the transfer hopper 14 from the discharge end. The material 5 in the transfer hopper 14 falls into the belt conveyor 16 by gravity and is sent to the guide hopper 17 by the belt conveyor 16. The guide hopper 17 guides the material 5 to the discharge assembly. Finally, the discharge assembly controls the material 5 to be accurately discharged into the carriage 6, thereby ensuring the loading amount of the current carriage 6, thereby helping to reduce the work of returning materials.

[0051] Specifically, refer to Figure 4 and Figure 5 The material discharging assembly includes a silo 22 provided on a traveling frame 21, an opening and closing member 23 connected to the silo 22, and a weight measuring member 24 for weighing the weight of the material 5 in the silo 22. The silo 22 is in the shape of a long cylinder and is distributed in the vertical direction. In this embodiment, the volume of the silo 22 is about 40 The outlet portion 171 of the guide hopper 17 extends into the silo 22. The bottom end of the silo 22 passes through the closed end of the traveling frame 21 and is located above the carriage 6. The bottom end of the silo 22 is in a contracted shape. The bottom end of the silo 22 contracts from top to bottom, which is conducive to guiding the material 5 in the silo 22 to flow out from the bottom. The opening and closing member 23 is provided at the bottom end of the silo 22. The opening and closing member 23 is used to open or close the bottom end of the silo 22. In this embodiment, the opening and closing member 23 is a jaw-type hopper door. The jaw-type hopper door has good sealing performance and can achieve very precise discharge control, which is conducive to achieving accurate discharge and reducing the loss of material 5.

[0052] During loading, the opening and closing parts 23 are in a closed state, the belt conveyor 16 transports the material 5 to the end, and guides the material 5 into the silo 22 through the guide hopper 17. The silo 22 guides the material 5 to near the bottom, and the weight of the material 5 is calculated by the weight measuring part 24. When the weight of the material 5 in the silo 22 reaches the preset weight of the carriage 6, the opening and closing parts 23 are controlled to open, and the material 5 falls into the carriage 6 by gravity, and the material 5 can be loaded into the carriage 6. At the same time, by driving the driving wheel 29 to rotate, the traveling frame 21 is driven to move back and forth in the carriage 6, so that the material discharge can be more uniform.

[0053] Reference Figure 4 and Figure 5The weight measuring member 24 is a pin-type weighing sensor. The pin-type weighing sensor is used to connect the force-bearing part to the sensor body. It can accurately sense the change of force and convert it into an electrical signal, which is conducive to reducing the influence of external interference, temperature changes or vibrations, thereby providing more stable and accurate weighing data. A base 25 is also provided on the silo 22. The base 25 is connected to the outer wall of the silo 22, and the base 25 is located above the traveling frame 21. A first connecting block 26 is provided on the side of the base 25 facing the traveling frame 21, and a second connecting block 27 is provided on the traveling frame 21 corresponding to the first connecting block 26. The second connecting block 27 is opposite to the first connecting block 26 in the vertical direction, and the second connecting block 27 is hinged to the first connecting block 26 through the weight measuring member 24, so that the material 5 in the silo 22 is weighed and measured by the weight measuring member 24.

[0054] Reference Figure 4 and Figure 5 An elastic member 28 is also provided on the base 25. The elastic member 28 is a spring. The elastic member 28 is distributed in the vertical direction. One end of the elastic member 28 is connected to the base 25, and the other end is connected to the walking frame 21. During weighing, the elastic member 28 can effectively absorb the vibration and impact from the silo 22 or the material 5 to play a buffering role.

[0055] Continue to refer to Figure 4 and Figure 5 There are two bases 25, which are arranged oppositely on both sides of the hopper. There are two first connecting blocks 26 corresponding to the number of bases 25, and the two first connecting blocks 26 are arranged one-to-one on the two bases 25. There are two second connecting blocks 27, weight measuring members 24, and elastic members 28. The two second connecting blocks 27 are hinged to the two first connecting blocks 26 one-to-one, and the second connecting blocks 27 are hinged to the first connecting blocks 26 through the weight measuring members 24. The two elastic members 28 are arranged on the two bases 25 one-to-one, and the two elastic members 28 are connected to the walking frame 21. This helps to improve the stability of the support for the silo 22, and the simultaneous detection by the two weight measuring members 24 helps to improve the accuracy and reliability of weighing.

[0056] In addition, refer to Figure 4 In order to prevent the material 5 from sticking to the wall of the silo 22, the silo 22 is also provided with a silo wall vibrator 30. The silo wall vibrator 30 is a prior art and will not be described in detail. The high-frequency vibration generated by the silo wall vibrator 30 can separate the material 5 attached to the silo wall, thereby avoiding the accumulation and blockage of the material 5.

[0057] The mainframe 12 is also equipped with a PLC control module, which is electrically connected to the weight measuring element 24, the opening and closing element 23, and the belt conveyor 16. A cable tray 31 is also provided on one side of the silo 22. One end of the cable tray 31 is connected to the silo 22, and the other end of the cable tray 31 is connected to the mainframe 12. The cable tray 31 is used to radiate power cables and communication cables, that is, the cable tray 31 serves to support and protect the cables.

[0058] During weighing, the weight is measured by the weight measuring piece 24. The control module receives the detection data of the weight measuring piece 24 and subtracts the gross weight of the equipment. At this time, the opening and closing piece 23 is in a closed state, and the belt conveyor 16 transports the material 5 to the silo 22. The weight measuring piece 24 detects in real time. When the weight of the material 5 reaches the preset weight of the carriage 6, the control module stops the belt conveyor 16 and drives the opening and closing piece 23 to an open state, thereby accurately loading the material into the carriage 6.

[0059] The implementation principle of the present application is as follows: when the travel control mechanism 11 drives the main frame 12 to move along the distribution direction of the dedicated track 3 and approaches the next carriage 6, the travel frame 21 is synchronously moved to the corresponding carriage 6 by driving the driving wheel 29 to rotate. At the same time, the material 5 is transported to the loading tail car 13 by the ground belt conveyor 4, and the material 5 of the loading tail car 13 is sent out of the transfer hopper 14 from the discharge end. The material 5 in the transfer hopper 14 falls into the belt conveyor 16 by gravity and is sent to the guide hopper 17 by the belt conveyor 16. The guide hopper 17 guides the material 5 into the silo 22. At this time, the opening and closing part 23 is in a closed state, and is weighed by the weight measuring part 24. The control module receives the detection data of the weight measuring part 24 and subtracts the gross weight of the equipment.

[0060] When the weight of the material 5 reaches the preset weight of the carriage 6, the belt conveyor 16 stops conveying. When the travel control mechanism 11 drives the main frame 12 to align with the next carriage 6, that is, when the travel frame 21 reaches the next carriage 6, the control module drives the opening and closing parts 23 to be in the open state, and the material 5 falls into the carriage 6 by gravity, and can be accurately loaded into the carriage 6. At the same time, by driving the driving wheel 29 to rotate, the travel frame 21 is driven to move back and forth at the carriage 6, so that the material unloading can be more uniform.

[0061] In summary, the material 5 is weighed while the equipment moves to the next carriage 6, and is loaded when the weighing is completed and reaches the carriage 6, which is beneficial to the overall continuous operation of the equipment and makes the loading more accurate, thereby reducing the return work.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
