Description

Technical Field

[0001] This invention relates to the field of rail wheel transfer and stacking technology, and in particular to a rail wheel production transfer and stacking device. Background Technology

[0002] Rail wheels (including train wheels, locomotive wheels, etc.) are core components of rail transit equipment. Their production is characterized by large raw material weight (usually hundreds of kilograms), irregular shape (complex rotating bodies with hubs, flanges, and treads), high precision requirements, numerous production processes (involving casting / forging, heat treatment, rough machining, finish machining, and testing), and a tight production schedule. In the production process, the transfer and temporary storage (stacking) of wheels between and within various processes are crucial for ensuring production continuity, improving site utilization, and enhancing logistics efficiency.

[0003] In real life, the stacking and transfer of rail wheels usually involves using a bridge crane to stack a set number of rail wheels onto a pallet, and then transferring them using general equipment such as forklifts. During the stacking process of the finished rail wheels, workers also need to place pads between the rail wheels to prevent scratches caused by relative friction between the rail wheels, which would affect product quality.

[0004] However, the existing technology still has certain shortcomings in its use: First, in the existing technology, during the stacking process using a bridge crane, the bridge crane first needs to lower its jaws, then clamp one of the rail wheels, then raise it to a certain height, then move it horizontally, and then lower it again to place the clamped rail wheel on the pallet. Then it resets and repeats the next placement step. In the above process, each pair of rail wheels requires steps such as lowering, clamping, raising, moving horizontally, lowering, placing, raising, and moving horizontally. To stack a set number of rail wheels, the overall path traversed during stacking is relatively long, resulting in low overall stacking efficiency. Second, when stacking and transferring the finished rail wheels, since no scratches are allowed on the surface of the rail wheels, in real life, when stacking multiple rail wheels, workers usually place pads between two rail wheels to reduce the friction and scratches between the rail wheels caused by shaking during transportation. However, the method of manually placing pads during the stacking of rail wheels using a bridge crane not only poses a significant safety hazard but also has low placement efficiency. Therefore, the existing technology needs further improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a transfer and palletizing device for the production of rail wheels, so as to solve the problems of long palletizing paths, low overall palletizing efficiency, low safety and low placement efficiency of manual placement of pads in the prior art.

Two sets of rectangular plates are symmetrically arranged on the left and right sides of the bracket. The inner sides of the two corresponding rectangular plates have vertically opened grooves five corresponding to the positions of the rod ends.

The top surface of the pallet body has six slots symmetrically opened on the front and back, with two slots six located on the front and back sides of the limiting post. An L-shaped support is vertically slidably arranged in the slot six, with the vertical section of the L-shaped support sliding in the slot six. A hydraulic cylinder four is arranged between the two strip columns, with a top plate at the top of the moving end of the hydraulic cylinder four. A limiting groove is opened through the top of the limiting post, and a limiting component is inserted into the limiting groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this application, the palletizing mechanism includes a moving part, a palletizing part, and a holding part. As the moving part descends and then rises, the palletizing part automatically stacks a set number of rail wheels on the T-shaped support blocks on both sides and between the two rectangular columns through two horizontally movable and symmetrically arranged T-shaped support blocks. After stacking the set number of rail wheels, the moving part moves horizontally and then moves with the pallet assembly in a single descent and ascent to place the stacked rail wheels onto the pallet body at once. Then, a horizontal movement and reset is performed to complete the entire palletizing process. Compared with the prior art, the palletizing steps in this solution greatly reduce the number of horizontal and vertical movements and greatly reduce the overall movement path, thereby greatly improving the overall efficiency of rail wheel body palletizing and transfer.

[0017] 2. In this application, during the stacking process of the rail wheel body by the cooperation of the moving part and the stationary part, the T-shaped support block can automatically supplement the L-shaped pad block in the slide groove two to the vertical adjacent rail wheel body during the horizontal reciprocating movement, so that the staff does not need to place the pad block accordingly. Only the L-shaped pad block needs to be supplemented later. This not only greatly improves the pad block placement efficiency, but also greatly improves the safety of rail wheel stacking and pad block placement, and is more practical.

[0018] 3. In this application, the retention part also includes a hydraulic cylinder two located below the support two. The top surface of the hydraulic cylinder two is provided with a column, and rectangular support blocks are symmetrically and horizontally movable on both sides of the column. A rectangular block with a columnar groove is provided in the groove of the protrusion. Through the cooperation of the hydraulic cylinder two, the column, the rectangular support block and the rectangular block with the columnar groove, multiple stacked rail wheel bodies can be supported during the stacking process. This not only avoids the large vertical pressure when the T-shaped support block moves horizontally, making the horizontal movement of the T-shaped support block smoother and improving the service life of the device, but also avoids the situation of falling during the stacking process caused by the height of the vertical surface at the end of the T-shaped support block, improving the stability during the stacking process and making the design more reasonable.

[0019] 4. In this application, the retention section also includes rods symmetrically arranged on the front and rear sides of the horizontal section of the T-shaped support block, and two sets of symmetrically arranged rectangular plates on the left and right sides of the bracket two. The inner side of the rectangular plates is provided with a sliding groove five and a sliding groove six. The sliding groove five is vertically opened. The upper section of the sliding groove six is ​​connected to the top of the sliding groove five and is inclined away from the sliding groove five, and then inclined to connect with the lower end of the sliding groove five. A rotatable rotating plate one is provided at the junction of the upper sections of the sliding groove five and the sliding groove six. In the initial state, the rotating plate one is in contact with the inner wall of the sliding groove five, thereby closing the sliding groove five, and then the T-shaped support block descends and then rises. The T-shaped support block first enters the guide rod of the rotating plate one into the slide groove six, and then moves vertically out through the slide groove five. This not only allows the T-shaped support block to automatically retract and move before contacting the rail wheel body, directly avoiding contact with the rail wheel body, thus reducing the possibility of scratching the surface of the rail wheel body and greatly improving the stacking quality, but also prevents the T-shaped support block from quickly resetting, which could cause the L-shaped pad block to shift or even fall off, thus improving the stability of the L-shaped pad block placement during the stacking process.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only a part of the embodiments disclosed in this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of this invention.

[0022] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0023] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0024] As attached Figure 1 As shown, in the prior art, the rail wheel body 1 has a protruding hub 2 in the middle of its upper side, and the hub 2 has a corresponding inner hole in the middle for connecting the shaft. The rail wheel body 1 has a tread 3 on its outer side, and a wheel flange 4 protruding from the tread 3 is provided on the lower side of the tread 3.

[0025] Please see Figure 2-17The present invention will now be described in detail with reference to the accompanying drawings and embodiments: A transfer and palletizing device for producing rail wheels includes a linear conveyor 5 for conveying processed rail wheel bodies 1, a support 6 above the linear conveyor 5, and a palletizing mechanism 7. The palletizing mechanism 7 includes a moving part 8 disposed on the support 6, a palletizing part 9 disposed at the output end of the moving part 8, and a holding part 10 disposed at the output end of the linear conveyor 5. A transfer mechanism 11 is disposed on one side of the linear conveyor 5. The transfer mechanism 11 includes a conveying component 12 and a pallet assembly 13 disposed at the output end of the conveying component 12. The palletizing part 9 moves vertically reciprocally via the moving part 8 and interacts with the holding part 10. The 0 unit can vertically stack the rail wheel bodies 1 that are conveyed to the holding section 10, and automatically fill the gaps between the rail wheel bodies 1 during the stacking process. The stacking section 9 can directly place a set number of rail wheel bodies 1 on the pallet assembly 13 through the horizontal movement of the moving section 8 and a single vertical movement, which greatly reduces the number of horizontal and vertical movements during the stacking process, greatly reduces the path required for stacking, and thus greatly improves the overall stacking efficiency. In addition, the pads are placed automatically without the need for manual operation, which greatly improves the safety and efficiency of the stacking process.

[0026] Please see Figure 1 , 9 The linear conveyor 5 is a roller conveyor. Guide plates 14 are symmetrically arranged on both sides near the output end of the roller conveyor to center and guide the rail wheel body 1. The guide plates 14 center the rail wheel body 1, thus facilitating its accurate entry into the corresponding position of the retention section 10. The roller conveyor in the above mechanism is existing technology and will not be described in detail here.

[0027] Please see Figure 3 The moving part 8 includes limiting blocks 15 symmetrically arranged on the top surface of the bracket 6. A sliding groove 16 is provided on the top surface of the bracket 6 between the limiting blocks 15. A lead screw 17 is rotatably arranged between the two limiting blocks 15. A motor 18 is fixedly arranged on the side of one of the limiting blocks 15. The output shaft of the motor 18 passes through and rotates on the side of the limiting block 15 and is fixedly connected to one end of the lead screw 17. A T-shaped moving block 19 is threaded on the lead screw 17. The vertical section of the T-shaped moving block 19 slides in the sliding groove 16. The bottom surface of the horizontal section of the T-shaped moving block 19 slides in contact with the top surface of the bracket 6. A hydraulic cylinder 20 is fixedly arranged on the bottom surface of the vertical section of the T-shaped moving block 19. A mounting plate 21 is fixedly arranged on the moving end of the hydraulic cylinder 20.

[0028] Please see Figure 4-8The stacking section 9 includes rectangular columns 22 symmetrically fixed to the bottom surface of the mounting plate 21. Rectangular grooves 23 are symmetrically formed on the lower inner sides of the two rectangular columns 22. T-shaped support blocks 24 are horizontally slidably arranged within the rectangular grooves 23. Springs 25 are fixedly installed between the horizontal sections on both sides of the vertical section of the T-shaped support block 24 and the inner wall of the rectangular groove 23. An inclined surface 26 is formed at the lower end of the horizontal section of the T-shaped support block 24. A vertical surface of a set height exists between the upper left end of the inclined surface 26 and the top surface of the T-shaped support block 24 to improve the support strength of the T-shaped support block 24 and prevent the T-shaped support block 24 from... When bending deformation occurs, when spring 25 is at its original length, most of the inclined surface of the T-shaped support block 24 is outside the rectangular column 22, and part of the vertical section of the T-shaped support block 24 is still inside the rectangular groove 23. A sliding groove 27 penetrating the top surface of the mounting plate 21 is opened in the rectangular column 22 directly above the vertical section of the T-shaped support block 24. A slot 28 communicating with the sliding groove 27 is opened at the bottom end of the inner side of the rectangular column 22. The sliding groove 27 and the slot 28 are adapted to the size of the L-shaped pad 30, so that the L-shaped pad 30 can fall vertically along the inner wall of the sliding groove 27 and horizontally along the slot 28. The rectangular column 22 has a slot 29 on its outer side that communicates with the rectangular groove 23. The size of the slot 29 is adapted to the size of the vertical end face of the T-shaped support block 24. The slot 29 provides space for the vertical section to move when the T-shaped support block 24 compresses the spring 25. Several L-shaped pads 30 are placed in the slide groove 27. When the L-shaped pads 30 in the slide groove 27 are used up, they can be replenished through the opening of the slide groove 27 on the top surface of the mounting plate 21. The horizontal section of the L-shaped pad 30 faces the slot 29, and the bottom surface of the lowest L-shaped pad 30 is vertical to the T-shaped support block 24. The top surface of the segment contacts the T-shaped support block 24. The horizontal segment is symmetrically equipped with limiting strips 31. The spacing between the limiting strips 31 is adapted to the width of the L-shaped pad block 30. The lower end of the slot 28 is provided with a sliding groove 32. The limiting strips 31 slide in the sliding groove 32, and the inner side of the limiting strips 31 and the side of the slot 28 are on the same vertical plane. Through the setting of the limiting strips 31 and the sliding groove 32, the L-shaped pad block 30 can be limited in the front and rear directions, which improves the stability of the L-shaped pad block 30 during the stacking of the rail wheel body 1, prevents the L-shaped pad block 30 from shifting, and improves accuracy.

[0029] Please see Figure 7The stacking section 9 also includes a receiving groove 33 opened on the top surface of the horizontal section of the T-shaped support block 24. A push block 34 is vertically slidably arranged in the receiving groove 33. A spring 35 is fixedly arranged between the bottom surface of the push block 34 and the bottom surface of the receiving groove 33. An inclined surface 36 facing the slide groove 27 is opened on the upper right side of the push block 34. When the spring 35 is at its original length, most of the inclined surface 36 is outside the T-shaped support block 24. When the spring 25 is at its original length, the push block 34 is on the left side of the L-shaped pad 30 on the top surface of the vertical section of the T-shaped support block 24. A slot 37 is opened on the right side of the bottom end of the slide groove 27.

[0030] As the T-shaped support blocks 24 on both sides move horizontally to the sides, the spring 25 is gradually compressed. At the same time, the inclined surface 36 of the push block 34 gradually contacts the L-shaped pad 30 on the top surface of the vertical section of the T-shaped support block 24. Because the L-shaped pad 30 is restricted by the inner wall of the slide groove 27 and other L-shaped pads 30 above, the L-shaped pad 30 on the top surface of the vertical section of the T-shaped support block 24 will not be displaced as the T-shaped support block 24 moves. As a result, the push block 34 is gradually squeezed back into the receiving groove. When the push block 34 enters the slot 37, the restriction on the push block 34 is released, and the push block 34 is reset by the spring 35. This causes the push block 34 to extend and be positioned to the right of the L-shaped pad 30 on the top surface of the vertical section of the T-shaped support block 24. At this time, when the T-shaped support block 24 is reset by the spring 25, the L-shaped pad 30 can be pushed out through the slot 28. After being pushed out, several L-shaped pads 30 in the slide 27 fall down, causing the lowest L-shaped pad 30 to fall onto the top surface of the vertical section of the T-shaped support block 24.

[0031] Please see Figure 6-7 The stacking section 9 also includes symmetrically arranged receiving grooves 38 on the front and rear sides of the slot 28. A limiting block 39 is horizontally slidably arranged in the receiving groove 38. A spring 40 is fixedly arranged between the limiting block 39 and the inner wall of the receiving groove 38. An inclined surface 41 is provided on the right side of the limiting block 39. When the spring 40 is at its original length, most of the inclined surface 41 on the limiting block 39 is outside the receiving groove 38. Through the horizontally slidable limiting block 39 and the inclined surface 41, it is possible not only to avoid obstructing the L-shaped pad 30 from being pulled out of the slide groove 27 by the push block 34, but also to prevent the L-shaped pad 30 outside the rectangular column 22 from being pulled back when the T-shaped support block 24 moves towards the slide groove 27 again. This ensures that the L-shaped pad 30 is between the two track wheel bodies 1 when they overlap.

[0032] When the T-shaped support block 24 is reset by the spring 25, the push block 34 pushes the L-shaped pad 30 outward together. During the movement, the vertical section of the L-shaped pad 30 contacts the inclined surface on the limit block 39, thereby squeezing the limit block 39 back into the receiving groove 38. When the spring 25 returns to its original length, the vertical section of the L-shaped pad 30 passes the limit block 39, thereby releasing the restriction on the limit block 39. The limit block 39 is reset by the spring 40. The reset limit block 39 can then prevent the L-shaped pad 30, which is outside the rectangular column 22, from moving towards the slide groove 27.

[0033] Please see Figure 9 The retention part 10 includes a second support 42. The top surface of the second support 42 has a protrusion 43 in the middle and is located directly below the two rectangular columns 22, so that the middle of the second support 42 is higher than the two sides. The length of the protrusion 43 of the second support 42 is less than the diameter of the rail wheel body 1. When the rail wheel body 1 is on the protrusion 43, the left and right ends of the rail wheel body 1 are suspended. The top surface of the protrusion 43 of the second support 42 has a groove 44. Several rollers 45 are rotatably arranged in the groove 44. The highest point of the rollers 45 is the same as the highest point of the roller of the roller conveyor and is higher than the top surface of the protrusion 43. One side of the second support 42 is in contact with the output end of the roller conveyor. The protrusion 43 of the second support 42 is located in the middle of the conveying path of the roller conveyor. The end of the protrusion 43 of the second support 42 away from the roller conveyor is detachably provided with an L-shaped limiting member 8146. The horizontal section of the L-shaped limiting member 8146 is provided with an arc-shaped groove that conforms to the contour of the wheel flange 4 of the rail wheel body 1.

[0034] When the rail wheel body 1 is conveyed to the conveying end by the roller conveyor, the rail wheel body 1 is guided in the center by the guide plate 14, and then faces the protrusion 43 of the rail wheel body 1 and the support 2 42. When the rail wheel body 1 moves to the output end, the front end of the rail wheel body 1 gradually falls into the roller 45 until it stops when it contacts the arc groove of the L-shaped limiting member 8146.

[0035] When one of the rail wheel bodies 1 is on the roller 45, the motor 18 is first started to drive the lead screw 17 to rotate. The rotation of the lead screw 17 drives the T-shaped moving block 19 to move horizontally, thereby causing the two rectangular columns 22 below the mounting plate 21 to move horizontally to directly above the bracket 42. Then, the hydraulic cylinder 20 is started to extend. The moving end of the hydraulic cylinder 20 carries the mounting plate 21 and the two rectangular columns 22 down. During the descent of the two rectangular columns 22, the inclined surfaces 26 of the T-shaped support blocks 24 on the left and right sides gradually contact the top of the tread surface 3 of the rail wheel body 1. As the two rectangular columns 22 continue to descend, the T-shaped support blocks 26 gradually move downward. 4. As the T-shaped support block 24 is pushed back into the rectangular groove 23 by the rail wheel body 1, the spring 25 is gradually compressed. At the same time, the inclined surface 36 of the push block 34 gradually contacts the L-shaped pad 30 on the top surface of the vertical section of the T-shaped support block 24. Since the L-shaped pad 30 is restricted by the inner wall of the sliding groove 27 and other L-shaped pads 30 above, the L-shaped pad 30 on the top surface of the vertical section of the T-shaped support block 24 will not be displaced with the movement of the T-shaped support block 24. As a result, the push block 34 is gradually pushed back into the receiving groove 33. When the vertical surface of the outer end of the T-shaped support block 24 is pressed into the rectangular groove 23, the push block 34 is pushed back into the receiving groove 33. When the rim 4 of the main body 1 contacts, the push block 34 enters the slot 4 37, and the L-shaped pad 30 releases its restriction on the push block 34. The push block 34 is reset by the spring 2 35, extends out of the receiving slot 1 33, and is located to the right of the L-shaped pad 30. When the T-shaped support block 24 passes the bottom surface of the track wheel body 1, the restriction of the track wheel body 1 on the T-shaped support block 24 is released, and the spring 1 25 resets, causing the T-shaped support block 24 to move out of the rectangular slot 1 23 again. During the process of moving out of the rectangular slot 1 23, since the push block 34 is located to the right of the L-shaped pad 30 at the bottom of the sliding groove 2 27, it will move the L-shaped pad 30 out of the rectangular slot 1 23 along with it. During the process of L-shaped pad 30 being moved out, the limiting block 39 will be squeezed back into the receiving groove 38 by the inclined surface 3 41. When the spring 25 returns to its original length, the horizontal section of L-shaped pad 30 and the horizontal section of T-shaped support block 24 are directly below the cantilevered parts on the left and right sides of the rail wheel body 1. Then, the hydraulic cylinder 20 is activated to retract, causing the two rectangular columns 22 to rise. During the rising process, the top surface of the horizontal section of L-shaped pad 30 on the left and right sides gradually contacts the bottom surface of the left and right sides of the rail wheel body 1. With further rising, the L-shaped pad 30 and T-shaped support block 24 on the left and right sides can lift the rail wheel body 1.

[0036] Then, the roller conveyor is restarted to transport the next rail wheel body 1 to the support 42. The two rectangular columns 22 descend again, and the two T-shaped support blocks 24 on the left and right are squeezed back into the rectangular groove 23 by the upper end of the tread surface 3 of the next rail wheel body 1 through the inclined surface 26. Due to the restriction of the limit block 39, the L-shaped pad 30 outside the rectangular column 22 will not move with the T-shaped support block 24. When the T-shaped support block 24 retracts into the rectangular groove 23, the rail wheel body 1 and the L-shaped pad 30 above descend and the bottom surface of the L-shaped pad 30 falls onto the top surface of the next rail wheel body 1, realizing the stacking of multiple rail wheel bodies 1. Then, the T-shaped support block 24 is moved over the bottom surface of the rail wheel body 1 again, so that the T-shaped support block 24 is reset and moves out with another L-shaped pad 30. Then, the hydraulic cylinder 20 is restarted to retract and lift the two stacked rail wheel bodies 1. Then, the above actions are repeated until the set number of rail wheel bodies 1 are stacked, so that there is no need for multiple horizontal reciprocating movements for stacking.

[0037] After the track wheel body 1 is stacked on top of the T-shaped support block 24, there is a set distance between the vertically adjacent L-shaped pads 30 on both sides. This set distance is less than the height of the vertical surface at the end of the T-shaped support block 24.

[0038] Please see Figure 10-12The retention part 10 also includes a hydraulic cylinder 47 located directly below the support 42. A rectangular block 48 is fixedly installed in the middle of the bottom surface of the groove 44. The top surface of the rectangular block 48 is at the same height as the top surface of the protrusion 43. A cylindrical groove 49 penetrating the bottom surface of the protrusion 43 is opened on the top surface of the rectangular block 48. The inner diameter of the cylindrical groove 49 is adapted to the inner diameter of the wheel hub 2 on the rail wheel body 1. Rollers 45 are located on both sides of the rectangular block 48. The diameter of the moving end of the hydraulic cylinder 47 is adapted to the diameter of the cylindrical groove 49. A column 50 is fixedly installed on the moving end of the hydraulic cylinder 47. A receiving groove 51 is symmetrically opened on the left and right sides of the column 50. The column 50 on the upper side of the receiving groove 51 still has a certain height. A rectangular support block 52 is slidably installed in the sliding groove 32. The outer surface of the rectangular support block 52 is set as an arc surface adapted to the outer diameter of the column 50. The lower outer end of the rectangular support block 52 is provided with an inclined surface 4 53. The inner side of the rectangular support block 52 is provided with a receiving groove 4 54. A spring 4 55 is fixedly installed between the inner wall of the receiving groove 4 54 and the inside of the receiving groove 3 51. A sliding rod 56 is fixedly installed on the inner side of both rectangular support blocks 52, and the two sliding rods 56 are staggered. Both sliding rods 56 pass through and slide on the inner wall of the receiving groove 3 51. The inner side of both rectangular support blocks 52 is provided with a cylindrical groove 2 57 adapted to the diameter of the sliding rod 56. The cylindrical groove 2 57 on one side corresponds to the position of the sliding rod 56 on the other rectangular support block 52. When the rail wheel body 1 contacts the arc groove of the L-shaped limiting member 8146, the inner hole of the hub 2 of the rail wheel body 1 is directly above the cylindrical groove 1 49.

[0039] When one railcar body is stacked on the T-shaped support block 24, and more need to be stacked, firstly, hydraulic cylinder 2 47 extends. The moving end of hydraulic cylinder 2 47 pushes column 50 upward along cylindrical groove 1 49. Since the inner hole of the hub 2 on the railcar body 1 is directly above cylindrical groove 1 49 and the distance between the bottom surface of the railcar body 1 and the top surface of the rectangular block 48 is small, column 50 extends directly through the inner hole of the hub 2 on the railcar body 1 as hydraulic cylinder 2 47 moves (i.e., rectangular support block 52 is still in receiving groove 3 51). When column 50 extends out of the inner hole of the hub 2 on the railcar body 1, rectangular support block 52 is reset by spring 4 55 and extends out of receiving groove 3 51. Then, hydraulic cylinder 1 20 extends, so that two... As the rectangular column 22 descends, the bottom surface of the hub 2 of the track wheel body 1 on the L-shaped pad 30 contacts the top surface of the extended rectangular support block 52. Then, as the rectangular column 22 descends further, the upper track wheel body 1 disengages from the L-shaped pad 30 on the T-shaped support block 24 (the upper track wheel body 1 rises relative to the inner walls of the two rectangular columns 22, and the top part of the column 50 is inside the inner hole of the hub 2 of the lower track wheel body 1, thus the rectangular support block 52 can stably support the track wheel body 1). Consequently, the T-shaped support block 24 is no longer under force, making it easier for the T-shaped support block 24 to move horizontally and reducing the force on the next track wheel body 1, thus reducing damage to the surface of the track wheel body 1. Then, the inclined surface on the T-shaped support block 24 contacts the end of the next rail wheel body 1, causing the T-shaped support block 24 to move into the rectangular groove 23. When the top surface of the T-shaped support block 24 passes downward over the top surface of the rail wheel body 1, the bottom surface of the L-shaped pad 30 on the T-shaped support block 24 falls onto the top surface of the outer end of the rail wheel body 1. Then, after the T-shaped support block 24 completely passes over the bottom surface of the rail wheel body 1 and brings out another L-shaped pad 30, the hydraulic cylinder 47 is activated to retract, causing the rectangular support block 52 to descend with the upper rail wheel body 1. During the descent, the outer bottom surface of the uppermost and lowest rail wheel body 1 falls onto the top surface of the horizontal section of the L-shaped pad 30 on the outer side of the lower rail wheel body 1 (at this time, the stacking of multiple rail wheel bodies 1 is completed). This avoids the situation where the upper rail wheel body 1 dips down due to the vertical surface at a certain height at the outer end of the T-shaped support block 24. As the moving end of the hydraulic cylinder 2 47 continues to retract, the inclined surface 4 53 on the rectangular support block 52 contacts the hub 2 of the lower rail wheel body 1 (at this time, the weight of the rail wheel body 1 is mainly borne by the protrusion 43, and the force between the rectangular support block 52 and the rail wheel body 1 is relatively small), causing the rectangular support block 52 to retract into the receiving groove 3 51. Then, the column 50 returns to the columnar groove 1 49, and then the hydraulic cylinder 1 20 is activated to retract, so that the T-shaped support block 24 and the L-shaped pad block 30 lift the stacked rail wheel bodies 1 together. Then, the above steps are repeated.

[0040] Please see Figure 5 , 13 -14. To avoid direct contact between the T-shaped support block 24 and the rail wheel body 1, the retention part 10 also includes symmetrically arranged rods 58 on the horizontal side of the T-shaped support block 24. The rectangular column 22 has symmetrically arranged sliding grooves 59 on its front and rear sides, allowing the rods 58 to slide horizontally within the sliding grooves 59. Two sets of rectangular plates 60 are symmetrically arranged on the left and right sides of the bracket 2 42. Vertically arranged sliding grooves 61, corresponding to the end positions of the rods 58, are formed on the inner sides of the two corresponding rectangular plates 60. The upper end of the sliding grooves 61 is connected to... The top surfaces of rectangular plates 60 are connected. The vertical groove 61 and the position of the rod 58 when the spring 25 is at its original length are on the same vertical line. The distance between the left and right rectangular plates 60 is greater than the diameter of the rail wheel body 1. A groove 62 is also provided on the inner side of the rectangular plates 60. The upper section of groove 62 is connected to the top of groove 61 and then slopes downward away from groove 61. The lower section of groove 62 slopes downward and then connects to groove 61. The widths of grooves 61 and 62 are adapted to the diameter of the rod 58. A rotating plate 63 is rotatably mounted at the junction of the upper ends of slide groove 61 and slide groove 62. The rotating plate 63 is located within the junction of slide groove 61 and slide groove 62. The rotation axis of the rotating plate 63 extends to the other side of the rectangular plate 60 and a rotating plate 64 is fixedly mounted thereon. A placement plate 65 is horizontally fixedly mounted on the side of the rectangular plate 60 away from the rotating plate 63. An arc-shaped rod 66 with its center coinciding with the rotation axis of the rotating plate 63 is fixedly mounted on the placement plate 65. The arc-shaped rod 66 is inserted into and slidably fitted with the rotating plate. An arc-shaped spring 67 is sleeved on the arc-shaped rod 66 located between the rotating plate 64 and the placement plate 65. The arc-shaped spring 67 is fixedly connected to the rotating plate 64 and the placement plate 65. When the arc-shaped spring 67 is at its original length, the inner wall of the top slide groove 61 of the rotating plate 63 is in contact with the plane of the rotating plate 63 and the inclined surface of the upper section of the slide groove 62 is on the same inclined surface. The rotating plate 63 is higher than the top surface of the track wheel body 1 located on the support 42. The rectangular column 22 is located between the front and rear rectangular plates 60.

[0041] When rod 58 approaches the lower section of slide groove 62, T-shaped support block 24 is located within rectangular groove 23.

[0042] As the two rectangular columns 22 descend, hydraulic cylinder 2 47 extends the top surface of column 50 out of the hub 2 of the rail wheel body 1, and makes the top surface of the extended rectangular support block 52 higher than the top surface of rectangular plate 60. The rectangular support block 52 first supports the rail wheel body 1 on the T-shaped support block 20, and then the ends of the two rods 58 enter the top opening of the slide groove 5 61. Then, guided by rotating plate 1 63, they enter the upper section of slide groove 6 62. When the rods 58 enter the upper section of slide groove 6 62, since the upper section of slide groove 6 62 is inclined downward and away from slide groove 5 61, the rods 58 gradually move away from support 2 42 along slide groove 4 59, so that the T-shaped support block 24 returns to the rectangular groove 1 23 before approaching the rail wheel body 1 (thus effectively avoiding contact between the T-shaped support block 24 and the rail wheel body 1, reducing...). (To reduce contact and thus reduce scratches), and the L-shaped pads 30 on the T-shaped support block 24 stay on the top surfaces of both sides of the rail wheel body 1. Then, when the rod 58 enters the lower section of the slide 62, the rod 58 gradually resets (when the rod 58 initially enters the lower section of the slide 62, the T-shaped support block 24 has already passed the bottom surface of the rail wheel body 1). The T-shaped support block 24, along with another L-shaped pad 30, is located on the bottom surfaces of both ends of the rail wheel body 1. Then, the rail wheel lift 1 is lifted by the hydraulic cylinder 20. During the lifting process, the rod 58 moves directly upward from the slide 61. When the rod 58 moves to the top of the slide 61, it pushes the rotating plate 63 open (i.e., the rotating plate deflects). After the rod 58 separates from the rectangular plate 60, the arc spring 67 resets the rotating plate 63 (i.e., the rotating plate 63 contacts the inner wall of the slide 61 again).

[0043] Please see Figure 15 The conveying assembly 12 includes symmetrically arranged strip columns 68. The top surface of the strip columns 68 is symmetrically provided with a groove 69 of a set length. An L-shaped moving platform 70 is slidably arranged on the bottom surface of the groove 69. The thickness of the horizontal section of the L-shaped moving platform 70 is less than the depth of the groove 69. An installation platform 71 is fixedly arranged between the two strip columns 68. A hydraulic cylinder 72 is fixedly arranged on the top surface of the installation platform 71. The moving end of the hydraulic cylinder 72 is fixedly connected to the vertical end face of the L-shaped moving platform 70. When the moving end of the hydraulic cylinder 72 is fully retracted, the vertical end face of the L-shaped moving platform 70 contacts the end face of the groove 69 and is flush with the support 42 at the same time. A slot 73 is provided on the top surface of the horizontal section of the L-shaped moving platform 70.

[0044] Please see Figure 15The pallet assembly 13 includes a pallet body 74. The bottom surface of the pallet body 74 has multiple parallel support legs. A limiting post 75, adapted to the inner diameter of the wheel hub 2 on the rail wheel body 1, is fixedly installed in the middle of the top surface of the pallet body 74. The top surface of the pallet body 74 has symmetrically opened slots 76 on both sides, located on the front and rear sides of the limiting post 75. An L-shaped support member 77 is vertically slidably installed within the slot 76. The vertical section of the L-shaped support member 77 slides within the slot 76. When the L-shaped support member 77 is in the water... When the flat bottom surface contacts the bottom surface of the pallet body 74, the bottom surface of the vertical section of the L-shaped support 77 is between the two legs and does not extend beyond the lower leg of the pallet body 74. A hydraulic cylinder 4 78 is provided between the two strip columns 68. A top plate 79 is fixedly provided at the top of the moving end of the hydraulic cylinder 4 78. The size of the top plate 79 is smaller than the size of the slot 5 73 and is adapted to the distance between the vertical sections of the two L-shaped support 77. A limiting groove 80 is opened through the top of the limiting column 75, and a limiting component 81 is inserted into the limiting groove 80.

[0045] The spacing between the left and right sides of the tray body 74 is adapted to the spacing between the two rectangular posts 22.

[0046] To further reduce scratches on the surface of the rail wheel body 1, a smooth layer is provided on the inclined surface 53 of the rectangular support block 52 and the side of the guide plate 14. The hardness of the smooth layer is lower than that of the rail wheel body 1. If low carbon / ordinary structural steel such as Q235 or No. 20 steel used in the prior art is adopted, its hardness is much lower than that of ER steel used in the rail wheel body, which will not be elaborated here.

[0047] After a set number of rail wheel bodies 1 are stacked on the T-shaped support block 24, hydraulic cylinder 3 72 is first activated to extend, pushing the L-shaped moving platform 70 to the end of the chute 7 69. Then, a pallet assembly 13 is placed on the L-shaped moving platform 70 using a forklift or other transport tool, and one end of the pallet body 74 is brought into contact with the vertical surface of the L-shaped moving platform 70. Then, hydraulic cylinder 3 72 is activated to retract and reset, so that the vertical surface of the L-shaped moving platform 70 is in contact with the end face of the chute 7 69. At this time, the pallet body 74 on the L-shaped moving platform 70 is aligned left and right with the bracket 2 42, and the top plate 79 on hydraulic cylinder 4 78, the slot 4 37, and the two L-shaped support members 77 are vertically aligned (this process can be carried out during the stacking process of the stacking mechanism 7). (During the process, this is done simultaneously). Then, motor 18 is started, which drives lead screw 17. Lead screw 17 drives T-shaped moving block 19 to move horizontally towards pallet body 74, thereby causing hydraulic cylinder 20 and rectangular column 22 to move together towards pallet body 74. When the inner hole of the wheel hub 2 on the track wheel body 1 inside the rectangular column 22 is vertically aligned with the limiting post 75 on pallet body 74, hydraulic cylinder 4 78 is then started to extend. The moving end of hydraulic cylinder 4 78 drives the top plate 79 to rise. The rising top plate 79 then pushes the two L-shaped support members 77 to rise to a set height (the vertical section of the L-shaped support member 77 has not left the slot 6 76). Then, hydraulic cylinder 20 is started to extend, and hydraulic cylinder 20 drives the palletizing track wheel body 1 to begin to descend. During the descent, the limiting posts 75 on the pallet body 74 gradually pass through the inner holes of the hubs 2 of the stacked rail wheel bodies 1. Then, the hub 2 of the lowest rail wheel contacts the top surface of the horizontal section of the two L-shaped support members 77. As the rectangular posts 22 continue to descend, the stacked rail wheel bodies 1 are supported at a certain height by the L-shaped support members 77 and the hydraulic cylinders 78 (at this time, the two lowest L-shaped pads 30 are still on the T-shaped support blocks 24 on the left and right sides). Then, the inclined surfaces 26 of the T-shaped support blocks 24 on the left and right sides gradually contact and press against the left and right sides of the pallet body 74, causing the T-shaped support blocks 24 on both sides to gradually retract into the rectangular grooves 23. When the top surface of the T-shaped support block 24 is lower than the top of the pallet body 74... When the pallet is in place, the L-shaped pads 30 fall on the top surfaces of the left and right sides of the pallet body 74. Then, the hydraulic cylinder 4 78 is activated to retract, which causes the pallet track wheel body 1 to descend. Finally, the pallet track wheel body 1 re-contacts the top surface of the horizontal section of the L-shaped pads 30 on the pallet body 74. Then, the top plate 79 is reset by the hydraulic cylinder 4 78. Then, the rectangular column 22 is lifted by the hydraulic cylinder 1 20. During the lifting process, since the distance between two adjacent L-shaped pads 30 is less than the height of the vertical surface of the end of the T-shaped support block 24, the hydraulic cylinder 1 20 can directly retract to separate the rectangular column 22 from the pallet track wheel body 1. Then, the rectangular column 22 is reset by the motor 18 for the next stacking.

[0048] After the rail wheels are placed on the pallet body 74, the hydraulic cylinder 3 72 is activated to extend and push the pallet body 74 and the rail wheel body 1 together to the end of the slide 7 69 via the L-shaped moving table 70. Then, the operator inserts the limiting piece 81 into the limiting groove 80. The pallet body 7 can then be replaced by a forklift or other conveying tool. This process can be carried out while the palletizing mechanism 7 is working.
