In this way, the warehouse management personnel can preferentially use the steel materials that have been stored for a long time, which helps the steel materials to be discharged in the first-in first-out mode, solves the problem that the steel materials at the bottom of the material pile cannot be taken out due to long storage time, and helps the warehouse to manage the steel materials.

Description

Technical Field

[0001] This invention belongs to the field of steel pipe storage technology, specifically relating to a steel storage device for railway vehicle production. Background Technology

[0002] The manufacturing of railway vehicle bodies requires various types of steel, such as round steel, steel pipes, I-beams, and square steel. For example, square steel and I-beams are used for welding the bottom beams of the vehicle body, while round steel and steel pipes are used for welding the frame columns. The steel is normally stored in the workshop's inventory area. When needed, the planning personnel issue the production requirements to the workshop, which then selects the appropriate quantity and specifications of steel and transports them to the production site. The steel is then welded, cut, and machined to meet the requirements of railway vehicle manufacturing.

[0003] After steel is purchased, inventory management personnel categorize and stack it according to type and specifications, typically placing the first-purchased steel at the bottom and the later-purchased steel on top. This current stacking method results in the first-purchased steel being piled at the bottom for extended periods, unable to be retrieved and used promptly. Prolonged storage may cause problems with the steel at the bottom of the pile, hindering warehouse management. Summary of the Invention

[0004] This invention provides a steel storage device for railway vehicle production, which aims to solve the problem that the existing storage method for bearing steel results in the steel at the bottom being stored for a long time and cannot be used in a timely manner, which is not conducive to the management of steel in the warehouse.

[0024] The steel storage device for railway vehicle production also includes a buffer assembly, which comprises:

[0025] A buffer block is rotatably disposed in the second receiving groove via a second rotating shaft. The buffer block has a third posture protruding from the second material loading surface and a fourth posture flush with the second material loading surface.

[0026] A second torsion spring, disposed on the second rotating shaft, is configured with a preload to rotate the second rotating shaft so that the buffer stop abuts against the side wall of the second receiving groove adjacent to the second feed inlet; and

[0027] A second limiting unit is disposed on the first material rack. The second limiting unit is detachably connected to the second rotating shaft and is used to limit the rotation of the second rotating shaft.

[0028] In one possible implementation, the second material-carrying surface is provided with a plurality of second receiving slots along the discharge direction of the discharge channel, and the buffer assembly is provided with a plurality of second receiving slots corresponding to the second receiving slots.

[0029] In one possible implementation, the bottom surface of the discharge channel is provided with a third receiving groove at one end near the second discharge port, and a plurality of the third receiving grooves are spaced apart along a first horizontal direction. The bottom surface of the discharge channel is also provided with a plurality of baffle blocks at one end near the second discharge port, and the baffle blocks are alternately arranged with the third receiving grooves.

[0030] The first transfer component includes:

[0031] Multiple material support plates, each corresponding to a third receiving groove, with one end of each support plate housed within its corresponding third receiving groove and the other end extending between two adjacent conveying rollers and forming a stop portion. The material support plates are inclined along the discharge direction of the discharge channel; and

[0032] Multiple first lifting units are connected to the corresponding material support plates and are used to drive the material support plates to lift.

[0033] In one possible implementation, the second rack has a second vertically arranged slide along one side adjacent to the conveying assembly, and the second transfer assembly includes:

[0041] The third driving component is disposed on the support beam and is used to drive the moving beam to move along the track;

[0042] A gripping mechanism, located on the moving beam, is capable of gripping and releasing steel.

[0043] Compared with the prior art, the beneficial effects of the steel storage device for railway vehicle production provided by the present invention are:

[0044] The steel storage device for railway vehicle production provided by this invention includes a conveying assembly, a first material rack, a feeding mechanism, a first transfer assembly, a second material rack, and a second transfer assembly. The first material rack can store round steel bars, steel pipes, and other steel materials with circular cross-sections, while the second material rack can store square steel bars, I-beams, and other steel materials with square or irregular cross-sections. When the steel needs to be released for use, the feeding mechanism and the first transfer assembly work together to transfer the steel pipes in the first storage space through the discharge channel to the conveying assembly. The second transfer assembly then transfers the steel in the second storage space to the conveying assembly, which transports it to other locations, completing the steel release. The released steel is then subjected to welding, cutting, and machining operations by operators to meet the needs of railway vehicle manufacturing.

[0045] This invention facilitates the categorization and three-dimensional storage of steel by setting up a first and second storage rack. Warehouse managers can store round steel, I-beams, square steel, and other steel required for railway vehicle production in either the first or second storage space according to their type and specifications. By incorporating a feeding mechanism, a first transfer assembly, and a second transfer assembly, steel can be retrieved from different storage spaces. Compared to the existing method of stacking steel, this invention achieves categorized storage of steel and allows for convenient retrieval of steel from different storage spaces as needed. This design also allows warehouse managers to prioritize the retrieval of steel that has been in storage for a longer period, facilitating a "first-in, first-out" (FIFO) inventory management system. It solves the problem of steel rusting, damage, and becoming unusable due to prolonged storage, thus contributing to the rational management of steel in the warehouse. Attached Figure Description

[0073] Please refer to the following: Figures 1 to 12 The following describes the steel storage device 1 for railway vehicle production provided in an embodiment of the present invention.

[0074] Please see Figures 1 to 3 This invention provides a steel storage device 1 for railway vehicle production, comprising a conveying assembly 10, a first material rack 20, a feeding mechanism 30, a first transfer assembly 40, a second material rack 50, and a second transfer assembly 60. The conveying assembly 10 includes a plurality of conveying rollers 11 spaced apart along a first horizontal direction and a plurality of first motors 12. The first motors 12 drive the corresponding conveying rollers 11 to rotate around an axis parallel to a second horizontal direction, which is perpendicular to the first horizontal direction. The first material rack 20 is located on one side of the conveying assembly 10 and has multiple layers of first storage spaces arranged from top to bottom. The multiple first storage spaces together form a storage area. The first material rack 20 also has a discharge channel located below the storage area. The first storage spaces and the discharge channel penetrate the first material rack 20 in the second horizontal direction. A first inlet is formed on the side of the first storage space adjacent to the conveying assembly 10, and a first outlet is formed on the side away from the conveying assembly 10. A second inlet is formed on the side of the discharge channel away from the conveying assembly 10. The first material storage space and the bottom surface of the discharge channel are inclined downwards along their respective discharge directions. The feeding mechanism 30 is located on the side of the first material rack 20 away from the conveying assembly 10 and is used to transfer steel near the first discharge port to the second material inlet. The first transfer assembly 40 is located on the side of the first material rack 20 adjacent to the conveying assembly 10 and is used to transfer steel near the second discharge port to the conveying roller 11. The second material rack 50 is located on one side of the conveying assembly 10 and has multiple layers of second material storage spaces arranged from top to bottom. The second material storage spaces form inlet and outlet ports on the side adjacent to the conveying assembly 10. The second transfer assembly 60 is located on the side of the second material rack 50 adjacent to the conveying assembly 10 and is used to transfer steel near the inlet and outlet ports to the conveying roller 11.

[0075] Compared with the prior art, the beneficial effects of the steel storage device 1 for railway vehicle production provided in this embodiment of the invention are:

[0076] The steel storage device 1 for railway vehicle production provided in this embodiment of the invention includes a conveying assembly 10, a first material rack 20, a feeding mechanism 30, a first transfer assembly 40, a second material rack 50, and a second transfer assembly 60. The first material rack 20 can store steel with a circular cross-section, such as round steel and steel pipes 2, while the second material rack 50 can store steel with a square or irregular cross-section, such as square steel and I-beams 3. When the steel needs to be released for use, the feeding mechanism 30 and the first transfer assembly 40 work together to transfer the steel pipes 2 from the first storage space to the conveying assembly 10 via the discharge channel. The second transfer assembly 60 transfers the steel from the second storage space to the conveying assembly 10, which then transports it to other locations, completing the steel release. The released steel is then subjected to welding, cutting, and machining operations by operators to meet the needs of railway vehicle manufacturing.

[0077] This invention, through the provision of a first rack 20 and a second rack 50, facilitates the classification and three-dimensional storage of steel. Warehouse managers can store steel in either the first or second storage space according to its type and specifications. By incorporating a feeding mechanism 30, a first transfer component 40, and a second transfer component 60, steel can be retrieved from different storage spaces. Compared to the existing method of stacking steel, this invention achieves categorized storage of steel and allows for convenient retrieval of steel from different storage spaces as needed. This arrangement also facilitates priority retrieval of steel with longer storage times by warehouse managers, promoting a "first-in, first-out" (FIFO) inventory management system. It addresses the problem of steel rusting, damage, and unusability due to prolonged storage, thus aiding in the rational management of steel in the warehouse.

[0078] The conveying assembly 10 includes multiple conveyors 2 that are rotatably arranged. The conveyor rollers 11 rotate to transport the steel (such as steel pipes 2 or I-beams 3) they carry to locations such as the cutting and blanking workshop, machining workshop, welding workshop, and workshop steel transfer vehicle. Figure 1 The first horizontal direction is the direction of steel conveying. Multiple conveying rollers 11 can be driven to rotate by a separate first motor 12, or they can be connected by chain drive or gear drive, with one motor simultaneously driving multiple conveying rollers 11. Compared to manual hoisting, the conveying assembly 10 improves the automation level of steel conveying, resulting in higher conveying efficiency for the conveying rollers 11, and also makes the conveying method safer.

[0079] The first rack 20 is used to store the purchased steel pipes 2 or round steel bars. Considering that various specifications and sizes of steel pipes 2 or round steel bars will be used in actual use, the first rack 20 has multiple layers of first storage space, which can realize classified storage and facilitate retrieval. For ease of explanation, the following description focuses on the case where the first rack 20 is used to store steel pipes 2. It can be understood that since the cross-sectional shape of steel pipes 2 or round steel bars is circular, they have versatility, and the first rack 20 provided in this embodiment of the invention can also be used to store round steel bars.

[0080] like Figure 1 , Figure 3 and Figure 6 As shown, the side of the first material rack 20 adjacent to the conveying component 10 is the feeding side, and the side away from the conveying component 10 is the discharging side. The feeding side has a first inlet, and the discharging side has a first outlet. When the material position is empty, the steel pipe 2 can be replenished from the first inlet. When replenishing the material, manual handling, hoisting, forklift handling, or other transportation methods can be used to assist in handling the steel pipe 2.

[0081] The first material rack 20 can be assembled from multiple rods and plates, such as Figure 1 As shown, the first material rack 20 may include multiple uprights, multiple first plates on the multiple uprights, and a second plate below the first plates. The upper surface of the first plate forms a first material-carrying surface 21 for supporting the steel pipe 2, and the upper surface of the second plate forms a second material-carrying surface 22 for supporting the steel pipe 2.

[0082] Both the first loading surface 21 and the second loading surface 22 are inclined surfaces with an inclination angle ranging from 3° to 10°. This allows the steel pipe 2 to roll along the direction from the first inlet to the first outlet on the first loading surface 21, and along the direction from the second inlet to the second outlet on the second loading surface 22. This configuration ensures that the steel pipe 2 that enters the warehouse first reaches the position adjacent to the first outlet and can be discharged first. This allows the first material rack 20 to discharge materials according to a "first-in, first-out" method, solving the problem of steel pipe 2 rusting and becoming unusable due to prolonged storage. This also facilitates the management of steel materials in the warehouse.

[0083] The feeding mechanism 30 is located on the side of the first material rack 20 away from the conveying assembly 10. It can reach the first storage space at different heights and take out the steel pipe 2 stored in the first storage space through the first discharge port and transfer it to the second inlet of the discharge channel. Finally, the steel pipe 2 reaches the first transfer assembly 40 from the second discharge port of the discharge channel. The first transfer assembly 40 transfers the steel pipe 2 to the top of the conveying roller 11 of the conveying assembly 10 and transports it to other positions by the conveying roller 11, thus completing the discharge and transportation of the steel pipe 2.

[0084] The feeding mechanism 30 can be a vertically movable robotic arm that uses mechanical gripping or magnetic adsorption to retrieve the steel pipe 2 from the first storage space and transfer it to the discharge channel. The first transfer component 40 can be a robotic arm or other transfer device that moves along a preset path and can transfer the steel material adjacent to the second discharge port onto the conveyor roller 11.

[0085] The second material rack 50 is located on one side of the conveying assembly 10. It can be located on the opposite side of the first material rack 20 or on the same side; there is no restriction on this. The only requirement is that the various components do not interfere with each other during operation.

[0086] The second storage rack 50 has multiple layers of secondary storage space, which can be used to store steel materials such as square steel, I-beams 3, and rail steel, realizing the classification and layered storage of steel materials for easy retrieval. For ease of explanation, this manual describes the situation when the second storage rack 50 is used to store I-beams 3. It also facilitates daily inspection, maintenance, and rust prevention of steel pipes 2. Each secondary storage space can store a single piece of steel or multiple pieces of steel, which can be configured by the user according to the actual situation.

[0087] The second transfer component 60 can remove the steel pipe 2 from the inlet / outlet in the second storage space and transfer it to the conveying component 10. The second transfer component 60 can be a robot arm or other transfer device that can move up and down, and can transfer the steel pipe 2 adjacent to the inlet / outlet to the conveying roller 11.

[0088] Please see Figure 3 and Figure 6 In some possible embodiments, the first material rack 20 is provided with a plurality of feeding trays 24 on one side adjacent to the conveying component 10. The feeding trays 24 correspond one-to-one with the first storage space. The upper surface of the feeding tray 24 is flush with the bottom surface of the corresponding first storage space. One end of the feeding tray 24 extends toward the conveying component 10, and the extension length of the feeding tray 24 increases at equal intervals from top to bottom with a preset length. The preset length is greater than the diameter of a steel piece.

[0089] In this embodiment, the feeding side of the first material rack 20 is provided with multiple feeding trays 24, and the multiple feeding trays 24 correspond one-to-one with multiple first storage spaces, which are used to support and guide the steel pipe 2 when replenishing the first storage space.

[0090] Considering that the workshop often uses a crane to lift materials from above for replenishment, in this embodiment, the extension length of multiple feeding pallets 24 arranged from top to bottom towards the side of the adjacent conveying component 10 increases sequentially, so that the multiple feeding pallets 24 do not affect each other in the vertical direction, and the steel pipe 2 can be smoothly lowered from above onto the corresponding feeding pallet 24, so that multiple first storage spaces can be replenished smoothly.

[0091] Please see Figures 1 to 3 In some possible embodiments, the first material rack 20 is provided with a first slide rail 23 on the side opposite to the conveying assembly 10. The feeding mechanism 30 includes a first material carrier plate 31, a first driving member 32, and a first pushing member 33. The first material carrier plate 31 is slidably fitted to the first slide rail 23; the first driving member 32 is disposed on the first material rack 20 and is used to drive the first material carrier plate 31 to move along the first slide rail 23; the first pushing member 33 is disposed at the end of the first material carrier plate 31 away from the first material rack 20 and has a first pushing end that extends and retracts along the discharge direction of the discharge channel.

[0092] In this embodiment, the feeding mechanism 30 includes a first loading plate 31. The first loading plate 31 has a first slider that cooperates with the first slide rail 23. The first driving member 32 can drive the first slider to move up and down. The first pushing member 33 is disposed on the side of the first loading plate 31 away from the conveying assembly 10. The first pushing end can extend and retract along the discharge direction of the discharge channel. During the up and down movement of the first slider, the first loading plate 31 is connected with the first loading surface 21 or the second loading surface 22 so that the steel pipe 2 can roll from the first discharge port onto the first loading plate 31 or roll from the first loading plate 31 to the second inlet.

[0093] During operation, the first driving component 32 drives the first carrying plate 31 to the height corresponding to the first storage space, retrieves the corresponding steel pipe 2, and then transports the steel pipe 2 downward to the second inlet. The first pushing component 33 pushes the steel pipe 2 into the discharge channel, allowing it to roll along the discharge channel to the second outlet. A robotic arm can be installed on the first carrying plate 31 or the first material rack 20 to grab the steel pipe 2 in the first storage space and place it on the first carrying plate 31.

[0094] The first loading plate 31 is used to support the steel pipe 2 that is discharged from the first discharge port. In order to prevent the steel pipe 2 from falling off during the movement of the first loading plate 31, the first loading plate 31 can be tilted downward at a certain angle along the direction from the first feed port to the first discharge port.

[0095] The first driving component 32 can be a vertically arranged hydraulic cylinder, pneumatic cylinder, or other lifting equipment such as a screw jack or scissor lift. The first pushing component 33 can be a pneumatic cylinder, hydraulic cylinder, electric telescopic rod, etc. There can be one first pushing component 33 or multiple first pushing components 33 arranged along the first horizontal direction to ensure that the steel pipe 2 is subjected to stable force.

[0096] Please see Figure 1 , Figure 3 , Figure 4 and Figure 6In some possible embodiments, the bottom surface of the first storage space is defined as the first loading surface 21. The first loading surface 21 has multiple first receiving slots 211 along the discharge direction of the first storage space. The steel storage device 1 for railway vehicle production also includes multiple limiting components spaced apart along the discharge direction of the first storage space. The limiting components are located in the corresponding first storage space, and a steel receiving position is formed between two adjacent limiting components. The limiting components include a limiting block 70, a first torsion spring, and a first limiting unit. The limiting block 70 is rotatably mounted on the first receiving groove 211 via the first rotating shaft 71. The limiting block 70 has a first posture protruding from the first material loading surface 21 and a second posture flush with the first material loading surface 21. The first torsion spring is mounted on the first rotating shaft 71 and is configured with a preload force to rotate the first rotating shaft 71 so that the limiting block 70 abuts against the side wall of the first receiving groove 211 adjacent to the first feed inlet. The first limiting unit is mounted on the first material rack 20 and is detachably connected to the first rotating shaft 71 to limit the rotation of the first rotating shaft 71.

[0097] During routine storage, the steel pipes 2 are confined between two adjacent limiting components, with each steel pipe 2 occupying one steel storage space, facilitating quantity counting and inventory management. When the limiting block 70 is in the first posture, the first rotating shaft 71 can be locked by the first limiting unit to prevent the first rotating shaft 71 from rotating. At this time, the limiting block 70 protrudes from the first loading surface 21, preventing the steel pipes 2 from rolling along the inclined surface. When discharge is required, the first limiting unit adjacent to the first discharge port releases its connection to the first rotating shaft 71, and the limiting block 70 switches to the second posture. The limiting block 70's restriction on the steel pipes 2 is released, allowing the steel pipes 2 to roll from the first discharge port onto the first loading plate 31 along the inclined first loading surface 21.

[0098] In this embodiment, the first rotating shaft 71 is preloaded via a first torsion spring, allowing the limiting block 70 to abut against the side wall of the first receiving groove 211 adjacent to the first feed inlet. The limiting block 70 protrudes from the first material loading surface 21. In the first posture, the limiting block 70 abuts against the side wall of the first receiving groove 211 adjacent to the first feed inlet, and the first limiting unit is connected to the first rotating shaft 71 to restrict its rotation. When it is necessary to release the restriction on the steel pipe 2, the first limiting unit first disconnects from the first rotating shaft 71. The steel pipe 2 rolls along the inclined plane under gravity, overcoming the preload of the torsion spring and pushing the limiting block 70 to rotate, causing it to be housed within the first receiving groove 211. The first torsion spring is further compressed. When the steel pipe 2 rolls out of the limiting block 70's range, the limiting block 70 automatically resets under the preload of the first torsion spring. The first limiting unit reconnects to the first rotating shaft 71, restricting its rotation.

[0099] After steel pipe 2 finishes discharging, the steel storage position adjacent to the first discharge port becomes vacant. The adjacent limiting component activates, releasing the limit on steel pipe 2 in the adjacent steel storage position. Steel pipe 2 then rolls to the steel storage position adjacent to the first discharge port, completing the replenishment at that position. Multiple limiting components along the direction away from the first discharge port activate sequentially, causing the remaining steel pipes 2 to advance one steel storage position at a time. After this process is complete, the steel storage position adjacent to the first feed port becomes vacant, and inventory management personnel can replenish material to that position.

[0100] Each limiting assembly may include a plurality of limiting blocks 70 spaced apart along a first horizontal direction (i.e., the axial direction of the steel pipe 2), and the first rotating shafts 71 of the plurality of limiting blocks 70 are coaxially and integrally connected. When the first limiting unit is connected to the first rotating shaft 71, the first rotating shaft 71 is restricted from rotating; when the first limiting unit is not connected to the first rotating shaft 71, the first rotating shaft 71 can rotate smoothly. The first limiting unit may be a gripper detachably connected to the first rotating shaft 71, capable of gripping or releasing the first rotating shaft 71.

[0101] In some possible embodiments, the first rotating shaft 71 has a limiting hole along the first horizontal direction, and the first limiting unit includes a limiting rod that extends and retracts along the first horizontal direction. The limiting rod faces the limiting hole, and when the limiting block 70 is in the first posture, the limiting rod is inserted into the limiting hole.

[0102] In this embodiment, the first limiting unit includes a limiting rod that is inserted into a limiting hole. When the limiting block 70 is in the first posture, the limiting rod and the limiting hole are coaxial. The limiting rod can move axially along the first rotating shaft 71 by means of electric, pneumatic, or hydraulic drive.

[0103] To address the issue that the long rolling distance and high speed of the steel pipe 2 along the discharge channel result in strong impact force, which can easily cause deformation of the discharge channel, and also causes significant impact force on the first transfer assembly 40 after the steel pipe 2 rolls out of the second discharge port, please refer to... Figure 1 , Figure 3 , Figure 5 and Figure 6In some possible embodiments, the bottom surface of the discharge channel is defined as the second material-carrying surface 22, and the second material-carrying surface 22 has a second receiving groove 221. The steel storage device 1 for railway vehicle production also includes a buffer assembly, which includes a buffer block 80, a second torsion spring, and a second limiting unit. The buffer block 80 is rotatably disposed on the second receiving groove 221 via a second rotating shaft 81. The buffer block 80 has a third posture protruding from the second material-carrying surface 22 and a fourth posture flush with the second material-carrying surface 22. The second torsion spring is disposed on the second rotating shaft 81 and is configured with a preload force to rotate the second rotating shaft 81 so that the buffer block 80 abuts against the side wall of the second receiving groove 221 adjacent to the second feed inlet. The second limiting unit is disposed on the first material rack 20 and is detachably connected to the second rotating shaft 81 to limit the rotation of the second rotating shaft 81.

[0104] In this embodiment, a buffer assembly is provided on the second material loading surface 22, which can decelerate the rolling steel pipe 2 or stop the steel pipe 2 after it comes into contact with the buffer stop 80, thereby reducing the rolling speed of the steel pipe 2 in the discharge channel. This solves the problem that the steel pipe 2 causes impact on the conveying assembly 10 or the first material rack 20 due to excessive moving speed, resulting in deformation of the parts.

[0105] The buffer assembly includes multiple buffer blocks 80 arranged along a first horizontal direction. These buffer blocks 80 are coaxially fixedly connected via a second rotating shaft 81, which is rotatably connected to the first material rack 20. During operation, under the action of a second torsion spring, the buffer blocks 80 are in a third position, simultaneously abutting against the side wall of the second receiving groove 221 adjacent to the second feed inlet. A second limiting unit is connected to the second rotating shaft 81, restricting its rotation. As the steel pipe 2 rolls downwards along the second loading surface 22, it contacts the buffer blocks 80, stopping its movement. Then, the second limiting unit activates, releasing the limiting position of the second rotating shaft 81. Under the weight of the steel pipe 2, the buffer blocks 80 are pressed down into the second receiving groove 221, at which point they are in a fourth position. The steel pipe 2 can then continue rolling downwards along the second loading surface 22, and the buffer blocks 80 return to their third position under the action of the second torsion spring.

[0106] The second limiting unit can be a gripper detachably connected to the first rotating shaft 71, capable of gripping or releasing the first rotating shaft 71. Alternatively, it can be a buffer rod that can be plugged into the second rotating shaft 81 via electric, pneumatic, or hydraulic drive.

[0107] In some possible embodiments, the second material-carrying surface 22 is provided with a plurality of second receiving slots 221 along the discharge direction of the discharge channel, and a plurality of buffer components are provided corresponding to the second receiving slots 221. By decelerating multiple times, the speed of the steel pipe 2 can be reduced, thereby reducing the impact force of the steel pipe 2 on the second material rack 50 and the first transfer component 40.

[0108] Please see Figure 1 , Figure 3 , Figure 6 and Figure 7 In some possible embodiments, the bottom surface of the discharge channel has a third receiving groove 222 at one end adjacent to the second discharge port. Multiple third receiving grooves 222 are spaced apart along the first horizontal direction. The bottom surface of the discharge channel also has multiple baffle blocks 25 at one end adjacent to the second discharge port. The baffle blocks 25 and the third receiving grooves 222 are alternately arranged. The first transfer assembly 40 includes multiple material support plates 41 and multiple first lifting units 42. The material support plates 41 correspond one-to-one with the third receiving grooves 222. One end of the material support plate 41 is accommodated in the corresponding third receiving groove 222, and the other end extends between two adjacent conveying rollers 11 and forms a stop part 411. The material support plates 41 are inclined along the discharge direction of the discharge channel. Multiple first lifting units 42 are connected to the corresponding material support plates 41 and are used to drive the material support plates 41 to lift.

[0109] When the steel pipe 2 is stopped at the second discharge port by the stop block 25, one end of the support plate 41 is below the steel pipe 2, and the other end is below the conveyor roller 11. When the first transfer assembly 40 is working, the first lifting unit 42 drives the support plate 41 to rise, and the support plate 41 lifts the steel pipe 2 to a height exceeding the stop block 25. The steel pipe 2 can continue to roll along the inclined surface of the support plate 41 until it abuts against the stop part 411, and the steel pipe 2 is above the conveyor roller 11. Then the first lifting unit 42 drives the support plate 41 to descend, and the steel pipe 2 falls back onto the conveyor roller 11 below, completing the transfer of the steel pipe 2.

[0110] Please see Figure 1 , Figure 8 and Figure 9 In some possible embodiments, the second material rack 50 is provided with a second slide rail 51 on the side adjacent to the conveying assembly 10. The second transfer assembly 60 includes a plurality of second pushers 61, a second carrier plate 62, and a second drive member 63. The plurality of second pushers 61 are respectively provided on the side of the second material rack 50 away from the conveying assembly 10 and correspond one-to-one with the second storage space. The second pusher 61 has a second push end facing the inlet and outlet. One end of the second carrier plate 62 is slidably engaged with the second slide rail 51, and the other end extends along the second horizontal direction. A clearance groove 621 for the conveying roller 11 to pass through is opened at the position corresponding to the conveying roller 11. The second drive member 63 is provided on the second material rack 50 and is used to drive the second carrier plate 62 to move along the second slide rail 51.

[0111] In this embodiment, the second loading plate 62 can move along the second material rack 50 under the drive of the second driving member 63, and the second pushing member 61 is disposed on the side of the second material rack 50 away from the inlet and outlet. When the I-beam 3 needs to be discharged, the second loading plate 62 first moves to the height of the corresponding second storage space, the second pushing member 61 extends, and pushes the I-beam 3 out of the inlet and outlet. The I-beam 3 reaches the second loading plate 62 and is located above the clearance groove 621. Then the second driving member 63 drives the second loading plate 62 to move downward. After the conveying roller 11 passes through the clearance groove 621, the I-beam 3 stops on the conveying roller 11, completing the transfer of the I-beam 3 from the second material rack 50 to the conveying assembly 10.

[0112] The second pusher 61 can be a pneumatic pusher, electric pusher, etc., facing the inlet / outlet, and the second drive unit 63 can be a hydraulic lift, scissor lift, screw jack, etc. To ensure smooth lifting of the second loading plate 62, a vertical guide rod 52 can also be provided, with the second loading plate 62 slidingly engaged with the guide rod 52.

[0113] Please see Figure 8 and Figure 9 In some possible embodiments, the second transfer assembly 60 further includes a third pusher 64, which is disposed at one end of the second carrier plate 62 away from the second material rack 50 and on the side of the conveyor roller 11 opposite to the second material rack 50. The third pusher 64 has a third push end facing the inlet and outlet.

[0114] In this embodiment, the third pusher 64 can push the I-beam 3 from the second carrier plate 62 to the second storage space, realizing the replenishment of steel pipes 2 such as the I-beam 3. In use, the second carrier plate 62 is located below the conveyor roller 11. The steel materials such as the I-beam 3 to be stored can be transported to one side of the second material rack 50 via the conveyor assembly 10. Then, the second drive member 63 drives the second carrier plate 62 to rise, lifting the I-beam 3 to the corresponding height. Finally, the third pusher end of the third pusher 64 extends, pushing the I-beam 3 from the inlet / outlet into the second storage space, completing the replenishment of steel materials. The third pusher 64 is arranged opposite to the second pusher 61 and can be a pneumatic pusher, electric pusher, etc., facing the inlet / outlet.

[0115] Please see Figures 10 to 12In some possible embodiments, the steel storage device 1 for railway vehicle production further includes a hoisting assembly 90, which includes a support beam 91, a moving beam 92, a third drive member, and a gripping mechanism 93. The support beam 91 is located above the first material rack 20 and has a track arranged along a second horizontal direction; the moving beam 92 is located on the side of the first material rack 20 forming the first feed inlet and slides with the track; the third drive member is located on the support beam 91 and is used to drive the moving beam 92 to move along the track; the gripping mechanism 93 is located on the moving beam 92 and is capable of gripping and releasing steel.

[0116] The hoisting assembly 90 can be a gantry crane, cantilever crane, or other transport machinery capable of lifting and transferring the steel pipe 2. When the steel pipe 2 is to be stored, it can be transported to the feeding side of the frame (i.e., the side of the frame with the feeding port) via the transport assembly, transport vehicle, or other transport device. The hoisting assembly 90 is used to transfer the steel pipe 2 to be stored on the transport assembly or transport device to above the corresponding feeding pallet 24, and then release the steel pipe 2, allowing it to roll along the inclined surface of the feeding pallet 24 and the first storage space to the vicinity of the first discharge port.

[0117] The hoisting assembly 90 includes a support beam 91, a moving beam 92, a third drive component, and a gripping mechanism 93. The support beam 91 is positioned above the first material rack 20. Driven by the third drive component, the moving beam 92 can move along a second horizontal direction, thereby transferring the hoisted steel pipe 2 above the corresponding feeding pallet 24. The first drive mechanism can be an electric hoist, a hydraulic push rod positioned along the first horizontal direction, etc. The moving beam 92 is equipped with a gripping mechanism 93, which includes a second lifting unit 931 and a gripping unit 932. The gripping unit 932 is used to grip the steel pipe 2 to be stored on the transport machinery or assembly; specifically, it can be a mechanical gripper, a magnetic chuck, etc., capable of firmly gripping the steel pipe 2. The second lifting unit 931 drives the gripping unit 932 to move vertically up and down, so that the gripping unit 932 and the steel pipe 2 reach above the corresponding feeding pallet 24. The gripping unit 932 releases the steel pipe 2, which falls onto the feeding pallet 24, completing the storage of the steel pipe 2. The second lifting unit 931 can be a vertically arranged screw jack, cylinder, hydraulic cylinder, etc.

[0118] In some possible embodiments, multiple gripping mechanisms 93 are arranged along a first horizontal direction, and the gripping unit 932 includes two first telescopic rods 933 and two lifting blocks 934. The two first telescopic rods 933 are respectively located at the lifting end of the second lifting unit 931, and the two first telescopic rods 933 are arranged opposite each other along a second horizontal direction; the two lifting blocks 934 are respectively located on the corresponding first telescopic rods 933, and the two lifting blocks 934 can be joined together under the drive of the first telescopic rods 933 to form a first space for the steel pipe 2 to pass through, and the lower surface of the first space is used to support the steel pipe 2.

[0119] In this embodiment, two first telescopic rods 933 are arranged opposite each other and can extend and retract synchronously. The two first telescopic rods 933 can be oppositely arranged cylinders, electric telescopic rods, etc. Each first telescopic rod 933 has a lifting block 934 at its telescopic end. Lifting slots are respectively opened on the sides of the two lifting blocks 934 adjacent to each other. When the material gripping mechanism grips the steel pipe 2, the second lifting unit 931 firstly drives the material gripping unit 932 to move to a suitable height, so that the steel pipe 2 and the two lifting slots are at the same height. Then, the two first telescopic rods 933 shorten synchronously, causing the two lifting slots to align, forming a first space for the steel pipe 2 to pass through. The steel pipe 2 is housed in the first space and supported by the lower surface of the first space. When it is necessary to release the steel pipe 2, the two first telescopic rods 933 extend synchronously, and the steel pipe 2 falls through the gap between the two lifting slots.

[0120] Since steel pipe 2 rolls towards the discharge port after entering the first storage space, the width of the first storage space needs to correspond to the axial length of steel pipe 2; a width that is too large or too small will cause problems. To ensure that steel pipe 2 can smoothly enter the first storage space when the hoisting assembly 90 is loading it, it is required that steel pipe 2 and the first feed inlet be aligned axially. If the axial distance between steel pipe 2 and the feed inlet is too large when steel pipe 2 is loaded, steel pipe 2 will not be able to smoothly enter the first storage space.

[0121] Please see Figure 10 , Figure 11 and Figure 12 To ensure that the steel pipe 2 is axially aligned with the first feed inlet when it enters the warehouse, in some possible embodiments, multiple gripping mechanisms 93 are spaced apart along the first horizontal direction. The hoisting assembly 90 also includes an adjustment mechanism 94, which includes a third lifting unit 941, a second telescopic rod 942, a mounting plate 943, an adjusting roller 944, and a second drive unit 945. The third lifting unit 941 is located on the moving beam 92 and between two of the second lifting units 931. The two second telescopic rods 942 are respectively located at the lifting ends of the third lifting unit 941 and are arranged opposite each other along the first horizontal direction. The two mounting plates 943 are respectively located on the corresponding second telescopic rods 942. The adjusting roller 944 is rotatably mounted on the corresponding mounting plate 943 along the vertical axis, and a second space for the steel pipe 2 to pass through is formed between the two adjusting rollers 944. The second space and the first space are linearly connected in the first horizontal direction. The two second drive units 945 are respectively located on the corresponding mounting plates 943 and are used to drive the corresponding adjusting rollers 944 to rotate.

[0122] In this embodiment, multiple gripping mechanisms 93 are provided along the second horizontal direction, making the lifting of the steel pipe 2 more stable. The hoisting assembly 90 also includes an adjustment mechanism 94, which can adjust the position of the steel pipe 2 along the second horizontal direction (i.e., the axial direction of the steel pipe 2) to align the steel pipe 2 with the first feed inlet, ensuring that the steel pipe 2 smoothly rolls into the first storage space through the first feed inlet.

[0123] When the hoisting assembly 90 is in operation, the gripping unit 932 first grips the steel pipe 2, allowing it to pass through the first and second spaces, with the bottom of the steel pipe 2 supported by the lower surface of the first space. Then, the two second telescopic rods 942 retract, causing the peripheral wall of the adjusting roller 944 to abut against the steel pipe 2. The second drive unit 945 drives the adjusting roller 944 to rotate, and the friction between the adjusting roller 944 and the steel pipe 2 drives the steel pipe 2 to move along the second horizontal direction, aligning the steel pipe 2 with the feed inlet axially. To increase the contact area between the adjusting roller 944 and the steel pipe 2, and to improve friction, a groove for accommodating the steel pipe 2 can be formed on the outer peripheral wall of the adjusting roller 944, and the inner wall of the groove can be designed to be made of rubber.

[0124] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present invention specification has recorded each combined embodiment and can support different combined embodiments.

[0125] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
