Description

Technical Field

[0001] This invention belongs to the technical field of intelligent loading and unloading systems for railway freight, and in particular relates to a container tipping machine for intelligent loading and unloading systems for railway freight. Background Technology

[0002] Currently, when transporting goods such as coal and gravel, open wagons or flatcars are usually used as the main means of transportation. Containers are placed inside the wagons. When the vehicle arrives at the unloading point, the container is first lifted out of the wagon, and then the container is flipped over to unload the goods, thus completing the unloading process.

[0003] Patent document CN115159331A discloses a container tilting device, including a fixed frame; an intermediate tilting frame disposed below the fixed frame for tilting the container; and a spreader disposed below the intermediate tilting frame for grabbing and lifting the container. The intermediate tilting frame is connected to the spreader via a lifting device. A tilting device is provided at the connection between the fixed frame and the intermediate tilting frame, which can tilt the intermediate tilting frame relative to the fixed frame. The main principle of this patent is that the spreader first grabs and lifts the container, allowing it to enter the tilting frame, and then the rotation of the tilting frame drives the container to rotate.

[0004] Typically, spreader arms use locking mechanisms that engage with the locking holes of the container corner fittings to grip the container. However, since the positions of the lock and the locking holes need to correspond, the position of the spreader arms needs to be adjusted. Additionally, before tilting, the tilting frame needs to be moved laterally to above the unloading hopper before tilting. Furthermore, after the container enters the tilting frame, it needs to be clamped to prevent it from disengaging during lateral movement and tilting. Summary of the Invention

[0005] The main objective of this invention is to provide a container tipping machine for intelligent loading and unloading systems for railway freight, which solves the problems of low efficiency and high cost of existing tipping machines due to structural limitations.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A container tilting machine for an intelligent loading and unloading system for railway freight includes a spreader for grabbing containers, a tilting frame capable of accommodating and tilting the spreader, and a lifting mechanism capable of driving the spreader up and down. The spreader is equipped with a spreader lock, which engages with a lock hole on the container for grabbing the container. The lifting mechanism includes a column and a pulley block, a lifting cylinder, and a wire rope installed inside the column. The column is installed in a transverse groove of the tilting frame. The lifting cylinder can drive the pulley to move up and down. One end of the wire rope is fixed to the pulley block, and the other end of the wire rope passes around the pulley block and is connected to the spreader. When the lifting cylinder extends or retracts, it drives the pulley to move, thereby driving the spreader to move up and down through the wire rope.

[0007] Preferably, the device also includes a lifting mechanism translation cylinder, which is mounted on the tilting frame. The telescopic end of the lifting mechanism translation cylinder is connected to the column and is used to drive the column to move in the transverse slide groove, thereby adjusting the position of the lifting device lock.

[0008] Preferably, the system also includes a clamping mechanism, which includes a clamping cylinder and a clamping plate. The clamping cylinder is mounted on a column, and the clamping plate is connected to the telescopic end of the clamping cylinder. When the clamping cylinder extends, it drives the clamping plate to act on the outer wall of the container.

[0009] Preferably, the two sides of the flipping frame are provided with a flipping mechanism for driving the flipping frame to rotate. The flipping mechanism includes a rotating disk, a roller assembly for supporting the rotating disk, and a flipping motor and a flipping gear for driving the rotating disk to rotate. A rotating gear is provided on the outer circle of the outer side of the rotating disk. The flipping motor drives the flipping gear, thereby driving the rotating disk to rotate on the roller assembly.

[0010] Preferably, the system also includes a walking mechanism, which includes a walking base, a walking motor, and a walking gear connected to the output end of the walking motor. The walking base is provided with a walking rack. When the walking motor is working, it drives the walking gear to rotate, and then the walking base moves back and forth through the meshing of the walking gear and the walking rack.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention employs an automated process: spreader locking, spreader lifting, container clamping, tilting frame movement, tilting frame tilting and unloading, tilting frame movement and retraction, container clamp release, container descent, spreader unlocking, and spreader retraction. Furthermore, because the tilting machine is designed with two symmetrically arranged tilting frames, it can simultaneously unload two containers each time. Preliminary testing shows that unloading two containers can be completed within 2.5 minutes, significantly improving the efficiency of the freight yard.

[0012] This invention uses a flipping motor to drive the flipping frame to rotate 360° for unloading, resulting in cleaner unloading.

[0013] This invention allows containers to be unloaded without landing when a train arrives at the freight yard, thus not occupying additional yard space and reducing the area required for the freight yard.

[0014] The lifting and clamping structures of this invention are all hydraulic, resulting in smoother operation.

[0015] Compared to existing flipping machines, this invention does not require large equipment and has low basic equipment costs. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1-4As shown, a container tilting machine for an intelligent loading and unloading system for railway freight includes two tilting devices arranged side by side and symmetrically. Each tilting device includes a spreader 1 for grabbing a container 101, a tilting frame 2 capable of accommodating the spreader 1 and tilting the spreader 1, and a lifting mechanism 3 capable of driving the spreader 1 up and down. The spreader 1 is square-shaped, with spreader locks 101 at its four corners. The four spreader locks 101 respectively cooperate with the lock holes at the four corners of the container 101. When grabbing the container 101, the spreader 1 is aligned vertically with the container 101. Then, under the action of the lifting mechanism 3, the spreader 1 descends into position. Finally, the spreader locks 11 are rotated electronically to complete the grabbing of the container 101. The lifting mechanism 3 includes two U-shaped lifting frames, each lifting frame including two... The uprights 31 are aligned left and right. Each upright 31 is equipped with a pulley block 33, a lifting cylinder 32, and a wire rope 34. The uprights 31 are installed in the transverse slide groove of the tilting frame 2. The pulley block 33 includes a fixed pulley and a movable pulley installed in the uprights 31. The movable pulley is installed at the telescopic end of the lifting cylinder 32 and can move up and down under the action of the lifting cylinder 32. A transition pulley is installed in the bridging part between the left and right uprights. The transition pulley is located above the lifting device 1. One end of the wire rope 34 is fixed to the fixed pulley, and the other end of the wire rope passes over the movable pulley and the transition pulley and connects to the lifting device 1. When the lifting device 1 is lifted upward, the lifting cylinder 32 extends and pulls the lifting device 1 upward through the wire rope 34. When the lifting device 1 is lowered downward, the lifting cylinder 32 retracts and the lifting device 1 falls under its own weight.

[0019] In this embodiment, the tilting frame 2 is provided with tilting mechanisms 4 on both sides for driving the tilting frame 2 to rotate. The tilting mechanism 4 includes a rotating disk 43, a roller assembly 42 for supporting the rotating disk 43, and a tilting motor 41 and a tilting gear (not shown in the figure) for driving the rotating disk 43 to rotate. A rotating gear 44 is provided on the outer circumference of the rotating disk 43. The tilting motor 41 drives the tilting gear 44, thereby driving the rotating disk 43 to rotate on the roller assembly 42. In this embodiment, each time the container 101 is tilted for unloading, the rotation amount of the tilting motor 41 is controlled to control the rotating disk 43 to rotate 360°, ensuring that the unloading is clean each time.

[0020] This embodiment also includes a walking mechanism 5, a walking base 51, a walking motor 52, and a walking gear 53 connected to the output end of the walking motor 52. A walking rack 54 is provided on the walking base 51. When the walking motor 52 operates, it drives the walking gear 53 to rotate. Since the walking gear 53 meshes with the walking rack 54, the walking base 51 moves back and forth via the walking rack 54 when the walking gear 53 rotates. Of course, for ease of movement, the walking base 51 can be mounted on a guide rail, and the movement process can be completed with the rollers at the bottom of the walking base 51.

[0021] This embodiment also includes a lifting mechanism translation cylinder 6, which is installed on the tilting frame 2. The telescopic end of the lifting mechanism translation cylinder 6 is connected to the column 31 and is used to drive the column 31 to move in the transverse slide, thereby adjusting the position of the spreader lock 11 so that the spreader lock 11 is aligned vertically with the lock hole at the corner of the container 101.

[0022] This embodiment also includes a clamping mechanism, which includes two clamping cylinders 71 (upper and lower) and clamping plates 72 connected to the telescopic ends of the two clamping cylinders 71. The clamping cylinders 72 are mounted on the columns 31. When the container 101 is lifted into the tilting frame 2 by the spreader 1, the two clamping cylinders 72 on the left and right columns 31 extend and push the clamping plates 72 to move, so that the clamping plates 72 act on the outer wall of the container 101, thereby clamping the container 101 and making the container 101 more stable during walking and tilting.

[0023] like Figure 5 As shown, the basic structure 102 is constructed of steel or concrete. When the scanning system detects an open wagon or flatcar entering the basic structure 102, it first determines whether the spreader 1 is aligned with the container 101. If not, the spreader 1 is moved laterally by the lifting mechanism translation cylinder 6 to adjust its position. After alignment, it is lifted, clamped, and then moves to the unloading position. After reaching the unloading position, the container 101 is rotated 360°, and the unloaded material is transported to the silo through the funnel 104, feeder 105, and belt conveyor 106.

[0024] The working principle of the tilting machine of the present invention is as follows: First, scan whether the spreader 1 is aligned with the container 101. If it is not aligned, the spreader 1 is moved laterally by the translation cylinder 6 of the lifting mechanism to adjust the position of the spreader 1. After alignment, the spreader 1 is lowered into position by the lifting mechanism 3. Then, the spreader lock 11 is rotated to lock the container 101. The spreader 1 is then lifted into position by the lifting mechanism 3. At this time, the clamping cylinder 71 is activated to clamp the container 101. Then, the travel motor 52 is activated to move the container 101 into position. At this time, the tilting motor 41 is activated to rotate the container 101 180° to pour out the material. The tilting motor 41 continues to work to rotate the container 101 another 180° to reset it. At this time, the travel motor 52 is activated to move the container 101 back into position. Then, the clamping mechanism is released, the lifting mechanism is activated, and the container 101 is lowered into the carriage. Finally, the mechanism is unlocked, and the spreader 1 returns to its initial position.

[0025] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
