[0007] The above-mentioned documents 1-3 also have the following technical defects:

[0008] 1) The storage capacity of a single storage device is insufficient;

[0009] 2) The structure of the storage device is too simple and cannot meet the requirements of continuous operation;

[0010] 3) The spring bars and gauge baffles are easily dispersed, resulting in uneven material storage. Summary of the Invention

[0011] In view of this, the purpose of this application is to provide a rail fastener storage device and a bulk material operation vehicle to solve the technical problems of low operating efficiency, small storage capacity and inability to meet continuous operation requirements of existing storage devices.

[0012] In order to achieve the above-mentioned invention objectives, the present application specifically provides a technical implementation solution of a rail fastener storage device, including:

[0013] An outer cylinder support component and an inner cylinder component are concentrically arranged from the outside to the inside, and the inner cylinder component adopts a circular rotating array structure for storing the rail fasteners to be released;

[0014] an inner cylinder rotating mechanism rotatably disposed between the outer cylinder support assembly and the inner cylinder assembly, the inner cylinder rotating mechanism being capable of driving the inner cylinder assembly to rotate relative to the outer cylinder support assembly, so as to rotate the track fastener to a discharge port position;

[0015] A turning mechanism provided on the side of the outer cylinder support assembly provides power for turning the outer cylinder support assembly and the inner cylinder assembly;

[0016] And a discharge port opening and closing mechanism is arranged at the bottom of the inner cylinder component, which is used to control the rail fastener to fall onto the material distribution device, and the discharge port is also the loading port.

[0017] When bulk material is being processed, the flip mechanism controls the outer barrel support assembly and the inner barrel assembly to flip, so that the discharge port is vertically downward. When loading is required, the flip mechanism controls the outer barrel support assembly and the inner barrel assembly to flip, so that the discharge port is converted into a loading port and maintains an oblique upward posture for loading.

[0018] Furthermore, the inner drum assembly is connected and mounted to the bulk material handling vehicle body via the outer drum support assembly. The outer drum support assembly comprises a circular frame structure composed of a top cover assembly, an outer frame assembly, and a base assembly. The top cover assembly and the base assembly are both connected to the outer frame assembly, allowing the inner drum assembly to be installed within the outer drum support assembly. Rotating shafts are provided on both sides of the outer frame assembly, and the top cover assembly is movably connected to the inner drum assembly. The discharge port opening and closing mechanism is provided on the base assembly.

[0019] Furthermore, the inner cylinder component includes a connecting plate, a motor connecting seat, a guide column, a connecting rod, a fixed plate and a guide seat. One end of the guide column is inserted into the corresponding hole on the connecting plate and fixedly connected thereto, and the other end of the guide column is a cantilever beam structure to facilitate the loading and unloading of the rail fasteners. The connecting plate adopts a circular structure, and the motor connecting seat adopts a cylindrical structure and is connected to the center of the connecting plate, so that the inner cylinder rotating mechanism drives the connecting plate to rotate together after being installed in the motor connecting seat. One end of the connecting rod is connected to the connecting plate, and the other end is connected to the guide seat. The middle part of the connecting rod is fixed by a fixed plate to increase the overall rigidity. The weight of the rail fastener loaded on the guide seat is transferred to the outer cylinder bracket component through the connecting plate via the connecting rod.

[0020] Furthermore, by adjusting the shape of the guide post to accommodate the loading of rail fasteners, the rail fasteners can be neatly arranged on a single guide post. The inner cylinder is provided with a plurality of guide posts arranged in a circular array to meet the rail fastener loading capacity required by the bulk material handling vehicle.

[0021] Furthermore, the inner drum rotation mechanism includes a slewing support, a motor mounting base, and a first reduction motor mounted on the motor mounting base. The inner drum rotation mechanism provides power for the rotation of the inner drum assembly, thereby sequentially rotating the rail fasteners mounted on the guide column to the discharge port. The top cover assembly is movably connected to the inner drum assembly via the slewing support. When the outer drum support assembly is fixed, the inner drum assembly can rotate under the action of the first reduction motor.

[0022] Furthermore, the flipping mechanism includes a second reduction motor and a bearing seat, wherein the second reduction motor is mounted on the rotating shaft via the bearing seat. The second reduction motor provides power for flipping the outer cylinder support component and the inner cylinder component together, thereby realizing the switching of the storage device between the working state and the loading state.

[0023] Furthermore, the discharge port opening and closing mechanism includes an opening and closing cylinder and an opening and closing baffle, which are used to control whether the rail fasteners on the guide column fall onto the material distribution device of the bulk material handling vehicle. The opening and closing cylinder is detachably connected to the opening and closing baffle, which is arranged along the circumference of the inner cylinder and is located at the bottom of the guide column. When the material distribution device is aligned below the discharge port, the piston rod of the opening and closing cylinder retracts to its shortest position, driving the opening and closing baffle at the discharge port position to slide toward the opening and closing cylinder, causing the rail fasteners on the guide column at this position to fall onto the material distribution device of the bulk material handling vehicle. When all the rail fasteners on the guide column have fallen, the piston rod of the opening and closing cylinder extends, driving the opening and closing baffle at this position to slide to its maximum position away from the closing cylinder. At this time, the inner cylinder rotation mechanism rotates to a set angle, causing the adjacent guide column to rotate to the discharge port position and begin to drop the material. The above action is repeated until all the rail fasteners on the guide columns in all rows have fallen.

[0024] Furthermore, a connector is provided at the piston rod end of the opening and closing cylinder, and a chute is provided at the bottom of the connector. The chute is releasably connected to a protrusion on the opening and closing baffle. The protrusion of the opening and closing baffle is driven by the inner cylinder rotation mechanism to rotate in and out of the chute of the connector, thereby connecting and disconnecting the opening and closing cylinder and the opening and closing baffle.

[0025] Furthermore, a plurality of guide posts are arranged along the circumference of the inner cylinder to form a circular array.

[0026] The present application also specifically provides a technical implementation solution for a bulk material operation vehicle, which includes: the rail fastener storage device as described above, and the rotating shaft composed of the outer frame is arranged on the mounting frame of the bulk material operation vehicle through a bearing seat.

[0027] By implementing the technical solutions of the rail fastener storage device and bulk material handling vehicle provided by the present application, the following beneficial effects are achieved:

[0028] (1) The rail fastener storage device and bulk material handling vehicle of the present application have a simple structure and a greatly increased storage capacity, capable of storing thousands of pieces. At the same time, the storage device is equipped with a transmission device to achieve continuous material replenishment, thereby doubling the operating efficiency.

[0029] (2) The rail fastener storage device and bulk material handling vehicle of the present application use a guide column with a shape similar to that of a spring bar or a gauge baffle to arrange the material in the inner cylinder, so that the spring bar and the gauge baffle can enter the material distribution device smoothly and orderly from the storage device. The spring bar and the gauge baffle are arranged neatly and orderly inside the storage device and are not easily dispersed. At the same time, the storage spring bar and the gauge baffle can be replaced according to the shape of the guide column, and the material has good compatibility;

[0030] (3) The rail fastener storage device and bulk material handling vehicle of this application have guide columns arranged in a ring matrix and an inner cylinder rotating device, which can ensure the orderly connection of materials and save storage space and conveying space of the storage device. At the same time, the overall use of a rotary support bearing method can meet both the requirements of rotation operation and the force requirements when fully loaded;

[0031] (4) The rail fastener storage device and bulk material handling vehicle of the present application have 20 rows of materials inside the storage device and only one discharge port. The 20 rows of materials are rotated one by one to the discharge port position for discharge through the internal rotating device. The discharge port of the storage device is also the loading port, which can solve technical problems such as the difficulty of orderly storage caused by the irregularity of the spring bars or gauge baffle materials.

DETAILED DESCRIPTION

[0056] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] As attached Figure 1 To the attached Figure 22 As shown, a specific embodiment of the rail fastener storage device and bulk material operation vehicle of the present application is given. The present application is further explained below in conjunction with the drawings and specific embodiments.

[0058] This application proposes a storage device for spring bars and gauge baffles for railway bulk material handling vehicles, as well as a bulk material handling vehicle. The storage device 10 comprises an outer cylinder support assembly 1, an inner cylinder assembly 2, an inner cylinder rotation assembly 3, a tilting mechanism 4, and a discharge port opening and closing mechanism 5. It enables the smooth and efficient delivery of spring bars and gauge baffles to a material distribution device 20. This application addresses the particularities of spring bars and gauge baffles, resulting in a simple structure, large storage capacity, and high operating efficiency, enabling continuous restocking operations.

[0059] Example 1

[0060] As attached Figure 1 and attached Figure 2 As shown, an embodiment of the rail fastener storage device of the present application specifically includes:

[0061] An outer cylinder support assembly 1 and an inner cylinder assembly 2 are concentrically arranged from outside to inside. The inner cylinder assembly 2 adopts a circular rotating array structure for orderly storing the rail fasteners 14 to be scattered (the rail fasteners 14 are scattered on the sleepers 9);

[0062] An inner cylinder rotating mechanism 3 is rotatably disposed between the outer cylinder support assembly 1 and the inner cylinder assembly 2. The inner cylinder rotating mechanism 3 can drive the inner cylinder assembly 2 to rotate relative to the outer cylinder support assembly 1, so as to rotate the track fastener 14 to the discharge port position;

[0063] The turning mechanism 4 provided on the side of the outer cylinder support component 1 provides power for turning the outer cylinder support component 1 and the inner cylinder component 2;

[0064] The discharge port opening and closing mechanism 5 is provided at the bottom of the inner cylinder component 2 and is used to control the rail fastener 14 to fall onto the material distribution device 20. The discharge port 16 is also the loading port.

[0065] The rail fasteners 14 primarily consist of spring bars and gauge plates. The inner cylinder assembly 2 is formed by a circular array of elliptical guide posts (the spring bar storage device comprises 40 guide posts, while the gauge plate storage device comprises 20 elliptical guide posts). While a single storage device in the prior art can hold approximately 100 items, the storage device 10 described in this embodiment can hold up to 1,760 items.

[0066] When bulk material is being processed, the turning mechanism 4 controls the outer cylinder support assembly 1 and the inner cylinder assembly 2 to turn over, so that the discharge port 16 is vertically downward. When loading is required, the turning mechanism 4 controls the outer cylinder support assembly 1 and the inner cylinder assembly 2 to turn over, so that the discharge port 16 is converted into a loading port and maintains an oblique upward posture for loading.

[0067] The inner cylinder component 2 is connected and installed on the body of the bulk material handling vehicle 8 through the outer cylinder bracket component 1. Figure 3 、 4 As shown in Figures 5 and 6, the outer cylinder support assembly 1 is a circular frame structure composed of a top cover assembly 11, an outer frame assembly 12, and a base assembly 13. Both the top cover assembly 11 and the base assembly 13 are bolted to the outer frame assembly 12. This flexible connection allows the inner cylinder assembly 2 to be installed within the outer cylinder support assembly 1. Rotating shafts 15 are provided on both sides of the outer frame assembly 12. The top cover assembly 11 is movably connected to the inner cylinder assembly 2. The discharge port opening and closing mechanism 5 is provided on the base assembly 13.

[0068] The main function of the inner tube component 2 is to store the spring bars or gauge baffles in an orderly manner as required. Figure 6 and attached Figure 7As shown, the inner cylinder assembly 2 further includes a connecting plate 21, a motor connecting seat 22, a guide post 23, a connecting rod 24, a fixing plate 25, and a guide seat 26. One end of the guide post 23 is inserted into a corresponding hole in the connecting plate 21 and fixedly connected thereto. The other end of the guide post 23 is a cantilever beam structure to facilitate the loading and unloading of the track fastener 14. The connecting plate 21 has a circular structure, and the motor connecting seat 22 has a cylindrical structure and is connected to the center of the connecting plate 21. When the inner cylinder rotation mechanism 3 is installed in the motor connecting seat 22, it drives the connecting plate 21 to rotate together. One end of the connecting rod 24 is connected to the connecting plate 21, and the other end is connected to the guide seat 26. The middle portion of the connecting rod 24 is fixed by a fixing plate 25 to increase overall rigidity. The connecting rod 24 transmits the weight of the track fastener 14 loaded on the guide seat 26 to the outer cylinder support assembly 1 through the connecting plate 21.

[0069] Spring bars and gauge baffles are easy to disperse, resulting in uneven storage. The rail fastener storage device described in Example 1 adapts to the loading of rail fasteners 14 by adjusting the shape of the guide column 23, so that the rail fasteners 14 can be neatly arranged on a guide column 23. The inner cylinder component 2 is provided with a plurality of guide columns 23 arranged in a circular array structure to meet the rail fastener loading capacity required by the bulk material operation vehicle 8. A plurality of guide columns 23 are arranged along the circumference of the inner cylinder component 2 to form a circular array. The entire inner cylinder component 2 is provided with 20 guide columns 23, all of which are arranged in an array, to meet the fastener (i.e., spring bar) loading capacity required by the bulk material operation vehicle 8. The function of the 10 connecting rods 24 is to bear the weight of the material, transfer the weight to the connecting plate 21, and then transfer it to the outer frame component 12. The function of the fixed plate 25 is to increase the rigidity of the inner cylinder component 2 when it rotates.

[0070] As attached Figure 8 As shown, the inner drum rotation mechanism 3 further includes a slewing support 31, a motor mounting base 32, and a first reduction motor 33 mounted on the motor mounting base 32. The inner drum rotation mechanism 3 provides power for the rotation of the inner drum assembly 2, thereby sequentially rotating the rail fasteners 14 loaded on the guide posts 23 to the discharge port. The top cover assembly 11 is movably connected to the inner drum assembly 2 via the slewing support 31. When the outer drum support assembly 1 is fixed, the inner drum assembly 2 can rotate under the power of the first reduction motor 33.

[0071] The turning mechanism 4 further includes a second reduction motor 41 and two bearing seats 7. The second reduction motor 41 is mounted on the rotating shaft 15 through the bearing seats 7. The second reduction motor 41 provides power for the outer cylinder support component 1 and the inner cylinder component 2 to turn together, so as to realize the storage device 10 in the working state (such as the attached Figure 9 A in the middle shows the working position) and the loading status (see the attached Figure 10 B in the figure shows the loading position) to switch between them.

[0072] As attached Figure 11 、 12 As shown in Figures 13 and 14, the discharge port opening and closing mechanism 5 further includes an opening and closing cylinder 51 and an opening and closing baffle 52, which are used to control whether the track fastener 14 on the guide column 23 falls onto the material distribution device 20 of the bulk material operation vehicle 8. The opening and closing cylinder 51 and the opening and closing baffle 52 are detachably connected. The opening and closing baffle 52 is arranged along the circumference of the inner cylinder component 2 and is located at the bottom of the guide column 23. Like the guide column 23, it adopts a circular matrix structure. When the material distribution device 20 is aligned below the discharge port 16, the piston rod of the opening and closing cylinder 51 retracts to its shortest position, driving the opening and closing baffle 52 at the discharge port position to slide toward the opening and closing cylinder 51, and the track fastener 14 on the guide column 23 at this position falls onto the material distribution device of the bulk material operation vehicle. When all the track fasteners 14 on the guide column 23 have fallen, the piston rod of the opening and closing cylinder 51 extends, driving the opening and closing baffle 52 at this position to slide to the maximum position in the direction away from the closing cylinder 51, and the inner cylinder rotating mechanism 3 rotates the set angle, so that the adjacent guide column 23 rotates to the discharge port position and starts to drop the material, and the above action is repeated until all the track fasteners 14 on all rows of guide columns 23 have fallen.

[0073] As attached Figure 12 As shown, a connector 53 is further provided at the piston rod end of the opening and closing cylinder 51. A chute 54 is provided at the bottom of the connector 53. The chute 54 is detachably connected to a protrusion 55 on the opening and closing baffle 52. The protrusion 55 of the opening and closing baffle 52 is driven by the inner cylinder rotation mechanism 3 to rotate in and out of the chute 54 of the connector 53, thereby connecting and disconnecting the opening and closing cylinder 51 and the opening and closing baffle 52.

[0074] Example 2

[0075] As attached Figure 14 To the attached Figure 22 As shown, an embodiment of the bulk material handling vehicle 8 of the present application specifically includes: the rail fastener storage device 10 as described in Example 1, and the rotating shaft 15 of the outer frame component 12 is arranged on the mounting frame 6 of the bulk material handling vehicle 8 through the bearing seat 7.

[0076] Example 3

[0077] As attached Figure 14 To the attached Figure 22As shown, an embodiment of a rail fastener storage operation method based on the device described in Example 1, the storage device 10 includes: an outer cylinder support component 1 and an inner cylinder component 2 concentrically arranged from the outside to the inside, an inner cylinder rotation mechanism 3 rotatably arranged between the outer cylinder support component 1 and the inner cylinder component 2, a flip mechanism 4 arranged on the side of the outer cylinder support component 1, and a discharge port opening and closing mechanism 5 arranged at the bottom of the inner cylinder component 2. The inner cylinder component 2 is provided with a plurality of guide columns 23 arranged in a circular array structure, and the discharge port opening and closing mechanism 5 includes an opening and closing cylinder 51 and an opening and closing baffle 52. The method specifically includes the following steps:

[0078] S1) Loading the storage device 10 at the base, by operating the flip mechanism 4 to flip the storage device 10 to a set angle (e.g., about 110°), so that the discharge port 16 at the bottom is in an inclined upward position;

[0079] S2) Controlling the opening and closing cylinder 51 to open the opening and closing baffle 52 at the discharge port 16 , and sequentially loading the rail fasteners 14 onto the guide post 23 at the discharge port 16 until the guide post 23 is full (e.g., 88 rail fasteners), and then controlling the opening and closing cylinder 51 to close the opening and closing baffle 52 at the discharge port 16 ;

[0080] S3) controlling the inner drum rotating mechanism 3 to rotate the inner drum assembly 2 by a set angle (e.g., 18°) so that the track fasteners 14 on the adjacent guide posts 23 rotate to the position of the discharge port 16;

[0081] S4) Repeat steps S2) to S3) until all guide posts 23 (e.g., 20) of the inner tube assembly 2 are loaded with the track fasteners 14;

[0082] S5) After the storage device 10 is fully loaded, the flip mechanism 3 is controlled to rotate approximately 110° in the opposite direction to step S1) to flip the entire storage device 10 to the working position, so that the discharge port 16 at the bottom is vertically downward and then stops, and the loading operation is completed;

[0083] When the (fastener) bulk material operation vehicle 8 arrives at the construction site, the next device of the storage device 10 (the material distribution device 20) is in operation;

[0084] S6) Rotate and control the feeding port of the material distribution device 20 to align with the discharging port 16 of the material storage device 10, and lock the material distribution device 20 and the material storage device 10;

[0085] S7) Controlling the opening and closing cylinder 51 to open the opening and closing baffle 52 at the discharge port 16, so that the track fastener 14 on the guide column 23 at this position falls onto the distributing device 20;

[0086] S8) The material distributing device 20 is activated to start distributing the material, and the track fasteners 14 on the guide column 23 fall down until they are all empty;

[0087] S9) After the sensor recognizes that all materials in the column have finished falling, it controls the opening and closing cylinder 51 to close the opening and closing baffle 52;

[0088] S10) Activating the inner drum rotating mechanism 3 to rotate the guide posts 23 adjacent to the discharge port 16 by a set angle (e.g., 18°) so that the material on the second row of guide posts 23 is transported to the discharge port 16;

[0089] S11) Repeat steps S7) to S10) until all the rail fasteners 14 in all guide columns 23 (eg, 20 columns) are emptied and the bulking operation is completed.

[0090] Among them, the cylinder can further adopt other types of pushing devices, such as oil cylinders, electric cylinders and other pushing methods, to ensure that the material can be stored in a rhythmic cycle.

[0091] The inner cylinder assembly 2 is connected and mounted to the bulk material handling vehicle 8 via the outer cylinder support assembly 1. The outer cylinder support assembly 1 is a circular frame structure composed of a top cover assembly 11, an outer frame assembly 12, and a base assembly 13. The top cover assembly 11 and the base assembly 13 are connected to the outer frame assembly 12 so that the inner cylinder assembly 2 can be installed inside the outer cylinder support assembly 22. The top cover assembly 11 is movably connected to the inner cylinder assembly 2, and the base assembly 13 is provided with a discharge port opening and closing mechanism 5.

[0092] The inner cylinder component 2 further includes a connecting plate 21, a motor connecting seat 22, a connecting rod 24, a fixing plate 25 and a guide seat 26. One end of the guide column 23 is inserted into the corresponding hole on the connecting plate 21 and fixedly connected thereto. The other end of the guide column 23 is a cantilever beam structure to facilitate the loading and unloading of the track fastener 14. The connecting plate 21 adopts a circular structure, and the motor connecting seat 22 adopts a cylindrical structure and is connected to the center of the connecting plate 21, so that after the inner cylinder rotation mechanism 3 is installed in the motor connecting seat 22, it drives the connecting plate 21 to rotate together. One end of the connecting rod 24 is connected to the connecting plate 21, and the other end is connected to the guide seat 26. The middle part of the connecting rod 24 is fixed by a fixing plate 25 to increase the overall rigidity. The connecting rod 24 transfers the weight of the track fastener 14 loaded on the guide seat 26 to the outer cylinder bracket component 1 through the connecting plate 21.

[0093] By adjusting the shape of the guide posts 23 to accommodate the loading of the rail fasteners 14, the rail fasteners 14 can be neatly arranged on a single guide post 23. Several guide posts 23 are arranged in a circular array within the inner cylinder assembly 2 to meet the rail fastener loading capacity required by the bulk material handling vehicle 8. Several guide posts 23 are arranged along the circumference of the inner cylinder assembly 2 to form a circular array.

[0094] The inner drum rotation mechanism 3 further includes a slewing support 31, a motor mounting base 32, and a first reduction motor 33 mounted on the motor mounting base 32. The inner drum rotation mechanism 3 provides power for the rotation of the inner drum assembly 2, thereby sequentially rotating the rail fasteners 14 mounted on the guide posts 23 to the discharge port. The top cover assembly 11 is movably connected to the inner drum assembly 2 via the slewing support 31. When the outer drum support assembly 1 is fixed, the inner drum assembly 2 can rotate under the power of the first reduction motor 33.

[0095] The turning mechanism 4 further includes a second reduction motor 41 and two bearing blocks 7, and the second reduction motor 41 is mounted on the rotating shaft 15 through the bearing blocks 7. The second reduction motor 41 provides power for turning the outer cylinder support assembly 1 and the inner cylinder assembly 2 together, thereby switching the storage device 10 between the working state and the loading state.

[0096] The discharge port opening and closing mechanism 5 further includes an opening and closing cylinder 51 and an opening and closing baffle 52, which are used to control whether the track fastener 14 on the guide column 23 drops onto the bulk material handling vehicle's material distribution device 20. The opening and closing cylinder 51 and the opening and closing baffle 52 are detachably connected and arranged along the circumference of the inner cylinder assembly 2 and located below the guide column 23. When the material distribution device 20 is aligned below the discharge port 16, the piston rod of the opening and closing cylinder 51 retracts to its shortest position, causing the opening and closing baffle 52 at the discharge port to slide toward the opening and closing cylinder 51, causing the track fastener 14 on the guide column 23 at this position to drop onto the bulk material handling vehicle 8's material distribution device 20.

[0097] When all the track fasteners 14 on the guide column 23 have fallen, the piston rod of the opening and closing cylinder 51 extends, driving the opening and closing baffle 52 at this position to slide to the maximum position in the direction away from the closing cylinder 51, and the inner cylinder rotating mechanism 3 rotates the set angle (such as 18°) to make the adjacent guide column 23 rotate to the discharge port position and start dropping, and repeat the above action until all the track fasteners 14 on the guide columns 23 in all rows (such as 20 rows) have fallen.

[0098] A connector 53 is threadedly mounted on the piston rod end of the opening / closing cylinder 51. A chute 54 is provided at the bottom of the connector 53, releasably connecting the chute 54 to a protrusion 55 on the opening / closing baffle 52. The protrusion 55 of the opening / closing baffle 52 is driven by the inner cylinder rotation mechanism 3 to rotate in and out of the chute 54 of the connector 53, thereby connecting and disconnecting the opening / closing cylinder 51 from the opening / closing baffle 52.
