Description

Technical Field

[0001] This utility model relates to the technical field of coal hopper cars, specifically a coal transport hopper car with anti-caking properties. Background Technology

[0002] In the coal transportation sector, hopper cars, with their central hopper structure and bottom door opening and closing mechanism, enable efficient automated or semi-automated lateral unloading, making them key equipment for large-volume, medium-to-long-distance railway transportation of coal. However, during coal transportation, especially under unfavorable conditions such as low temperature, humidity, or high moisture content of the coal itself, coal is highly susceptible to caking inside the car body.

[0003] To address the problem of coal caking and blockage during unloading, existing technologies mostly involve workers using sledgehammers to violently strike the outer walls of the car body or inserting steel bars into the unloading port to tamp the coal, or installing vibrators on the outside of the hopper car body to generate strong vibrations during operation in an attempt to shake off the caking coal. However, these manual or mechanical methods of striking and vibrating can damage the car body. The strong, concentrated impact force of the sledgehammer acts directly on the car body walls, easily causing localized plastic deformation. Furthermore, the repeated impact points become stress concentration points, accelerating the generation and development of fatigue damage in the plates and inducing microcracks that are difficult to detect. The overall rigidity and strength of the car body structure are significantly weakened, thus affecting its service life. Therefore, we propose an anti-caking coal transport hopper car. Utility Model Content

[0004] The purpose of this utility model is to provide a coal transport hopper car with anti-caking properties, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A piston rod is fixedly connected to the bottom of the movable plate, and the piston rod passes through the bottom of the carriage. A piston cylinder is sleeved at the end of the piston rod.

[0009] Preferably, the piston cylinder includes a power cylinder and a buffer cylinder. The power cylinder has a vent hole on its side and a connecting pipe is fixedly connected to the side of the power cylinder. The connecting pipe communicates with the interior of the piston cylinder. The bottom of the carriage has a through hole corresponding to the piston rod structure.

[0010] Preferably, the bottom of the carriage is connected to a frame, the middle of the bottom of the carriage is connected to a hopper, and the side of the hopper is connected to a material gate.

[0011] Preferably, a pressure relief pipe is fixedly connected to the bottom end of the power cylinder, a solenoid valve is connected to the pressure relief pipe, and the end of the pressure relief pipe is located on the side of the discharge hopper.

[0015] By employing the above technical solution, this utility model provides a coal transport hopper car with anti-caking properties, which has at least the following beneficial effects:

[0016] (1) This utility model moves the coal pile by a lifting structure moving plate, thereby destroying the caking area by the overall deformation of the coal pile. At the same time, the rapidly falling moving plate causes the local coal pile to fall synchronously, and the vibration generated by the weight of the coal pile itself destroys the caking area, thereby facilitating the unloading operation of the caking coal pile and improving the unloading efficiency.

[0017] (2) The present invention uses the weight of the coal pile to quickly discharge the air inside the piston cylinder by setting the pressure relief pipe, and forms a high-speed airflow at the pipe opening, which will disperse the coal pile that may be caking near the feeding hopper and improve the feeding efficiency of the coal pile.

[0018] (3) The present invention can cover the top of the carriage when it rains by setting the rainproof cloth structure, reducing the amount of rainwater that seeps into the coal pile, and reducing the probability of coal pile caking from the source. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] A coal transport hopper car with anti-caking properties, such as Figure 1 , Figure 4 , Figure 5 As shown, it includes carriage 1;

[0029] The carriage 1 is equipped with a vibration and dispersing mechanism 2, which can push and vibrate the coal pile loaded inside the carriage 1. By utilizing the changes in the internal structure of the coal pile during the pushing process, the caking area is squeezed and deformed. At the same time, the vibration generated by the rapid fall can disperse the coal pile accumulated in the area of ​​the unloading hopper 4 to facilitate the unloading operation.

[0030] Specifically, the dispersing mechanism 2 includes a movable plate 21, which is slidably connected to the bottom of the car body 1. A piston rod 22 is fixedly connected to the bottom of the movable plate 21, which passes through the bottom of the car body 1. A piston cylinder 23 is sleeved at the end of the piston rod 22. The movable plate 21 has a zigzag structure, consisting of two plates connected at their ends. The angle of the movable plate 21 is similar to the angle of the bottom of the car body 1. The piston rod 22 can cooperate with the piston cylinder 23 to pressurize the inside of the piston cylinder 23 using the train's own air duct system. This high pressure pushes the movable plate 21 and the coal pile, breaking up the caking structure of the coal pile that may be caking due to accumulation by deforming the local protrusion in the middle, thus facilitating the unloading operation of the coal pile. At the same time, by releasing the air pressure inside the piston cylinder 23 instantaneously, the impact generated by the weight of the entire coal pile falling further disperses the caking coal pile.

[0031] Furthermore, the piston cylinder 23 includes a power cylinder 231 and a buffer cylinder 232. The power cylinder 231 has a vent hole on its side and a connecting pipe is fixedly connected to the side of the power cylinder 231. The connecting pipe is connected to the inside of the piston cylinder 23. The bottom of the car body 1 has a through hole 24 corresponding to the structure of the piston rod 22. The structure of the power cylinder 231 can provide power for the lifting and lowering of the moving plate 21. At the same time, the structure of the buffer cylinder 232 can buffer the instantaneously falling coal pile and the moving plate 21, reducing the damage caused by the collision between the moving plate 21 and the car body 1. The downward tilting moving plates 21 on both sides can cooperate with the bottom of the car body 1, which can reduce the amount of coal powder that seeps into the space between the moving plate 21 and the car body 1 during the lifting and lowering process.

[0032] It is worth noting that the bottom of the carriage 1 is connected to the frame 3, the middle of the bottom of the carriage 1 is connected to the hopper 4, and the side of the hopper 4 is connected to the material gate 5. The frame 3 can support the carriage 1, and the hopper 4 can facilitate the unloading of coal from the inside of the carriage 1.

[0033] Based on this, a pressure relief pipe 25 is fixedly connected to the bottom of the power cylinder 231, and a solenoid valve 26 is connected to the pressure relief pipe 25. The end of the pressure relief pipe 25 is located on the side of the feeding hopper 4. The structure of the pressure relief pipe 25 can quickly depressurize the air inside the piston cylinder 23. At the same time, the end of the pressure relief pipe 25 is located inside the feeding hopper 4. By setting a small-diameter pressure relief pipe 25, the high-pressure gas discharged instantaneously can be used to form an air knife to impact the coal pile near the feeding hopper 4, further improving the efficiency of coal pile feeding.

[0034] Example 2

[0035] like Figures 1-3As shown, based on Embodiment 1, the carriage 1 is equipped with a rain-proof mechanism 6. The rain-proof mechanism 6 can cover the top of the carriage 1 during vehicle operation, shielding the open top of the carriage 1, reducing the amount of rainwater seeping into the interior of the carriage 1, and reducing the amount of coal pile caking caused by rainwater.

[0036] In this embodiment, the rain-proof mechanism 6 includes a movable frame 61, and a rain-proof cloth 62 is connected inside the movable frame 61. One end of the rain-proof cloth 62 is fixedly connected to the carriage 1. The movable frame 61 can move along the top of the carriage 1 to unfold the rain-proof cloth 62, thereby providing rain protection for the carriage 1. The movable frame 61 has a U-shaped structure or a zigzag structure, which can cover the coal pile that protrudes in the middle of the top due to overloading.

[0037] In addition, a storage rod 63 is rotatably connected inside the movable frame 61, and the other end of the rain cover 62 is fixedly connected to the storage rod 63. A coil spring 64 is fixedly connected to one end of the storage rod 63. The structure of the storage rod 63 can wrap and store the rain cover 62, while the structure of the coil spring 64 can reset the storage rod 63, so that the unfolded rain cover 62 can be automatically stored.

[0038] It is worth noting that a motor 65 is fixedly connected to the top of the interior of the carriage 1. A synchronous pulley 66 is connected to the end of the output shaft of the motor 65 and the end of the carriage 1 away from the motor 65. The synchronous pulley 66 is rotatably connected to one end of the carriage 1. A synchronous belt 67 is connected to the synchronous pulley 66. The two ends of the synchronous belt 67 are fixedly connected to the moving frame 61. The structure of the synchronous belt 67 can control the moving frame 61 to move along the top of the carriage 1.

[0039] When using the anti-caking coal transport hopper car of this utility model, when the vehicle travels from a sunny area to a rainy, snowy, or hailous area, the crew can start the motor 65. The motor 65 drives the synchronous belt 67 to move through the synchronous pulley 66, thereby moving the moving frame 61 from one end of the top of the car body 1 to the other end. During the movement of the moving frame 61, since one end of the rain cover 62 is fixed to the car body 1, the rain cover 62 unfolds and covers the top of the open car body 1.

[0040] When feeding coal into the car body 1, the feeding hopper 4 is opened first, and air is continuously injected into the power cylinder 231 of the air duct box. At the same time, the solenoid valve 26 on the pressure relief pipe 25 is periodically opened and closed.

[0041] When the solenoid valve 26 closes the pressure relief pipe 25, the air pressure inside the power cylinder 231 increases due to the continuous injection of air. This air pressure then pushes the moving plate 21 and the local coal pile upwards, causing the coal pile to deform and breaking up any possible caking inside.

[0042] When the solenoid valve 26 opens the pressure relief pipe 25, the air inside the power cylinder 231 and the air duct is discharged through the pressure relief pipe 25. At this time, the pressure inside the power cylinder quickly switches from a high-pressure state to the same as the ambient air pressure. Therefore, the heavier coal pile descends rapidly under the action of gravity. When the moving plate 21 approaches the bottom of the car body 1, the piston rod 22 quickly approaches the bottom of the buffer cylinder 232. Since the buffer cylinder 232 is a closed structure, the air pressure inside the buffer cylinder 232 increases rapidly, buffering the moving plate 21 that is approaching the bottom and reducing the damage to the moving plate 21 caused by the collision. At the same time, the coal pile impacts adjacent coal blocks due to the sudden drop in speed, further breaking up the caking. Meanwhile, due to the push of the heavy coal pile, the gas inside the power cylinder 231 is rapidly discharged outward from the pressure relief pipe 25, thus forming a high-speed airflow at the pipe opening, which impacts the coal pile near the discharge hopper 4, improving the discharge efficiency of the coal pile.
