TECHNICAL FIELD
[0001] The utility model belongs to the field of bulk material unloading technology of railway transportation relates to a device for assisting the tipper to unload the open-top container transported by the open wagon. BACKGROUND
[0002] With the increasing importance of railway transportation in the modern logistics system, the transportation and unloading technology of bulk materials has attracted widespread attention. In railway transportation, the tipper, as an efficient unloading equipment, is widely used in the unloading operation of bulk materials. The tipper on the market is mainly divided into two types: one is the ordinary tipper, whose design purpose is limited to unloading bulk materials in the railway open wagon; the other is the multifunctional tipper, which can handle ordinary open wagons and open-top containers transported by special flat cars. The design of these two types of tippers has its own specificity and can meet the specific transportation and unloading needs. However, in actual application, due to the differences in the allocation and use of railway transportation resources, especially under the current situation of tight railway flat car capacity, many enterprises have adopted the mode of transporting open-top containers by railway open wagons. Although this mode of transportation has to some extent alleviated the problem of insufficient capacity, it has also brought new challenges.
[0003] The mode of transporting open-top containers by railway open wagons faces significant technical difficulties in the unloading link. Due to the structural differences between the open wagon and the open-top container, the existing ordinary tipper and multifunctional tipper cannot effectively solve the problem of compacting and positioning the container during unloading. The ordinary tipper is mainly designed for bulk materials in the open wagon, and its clamping mechanism cannot adapt to the external structure of the container; while the multifunctional tipper can handle containers on special flat cars, but when it comes to open-top containers transported by open wagons, it still lacks effective fixing measures. If the tipper is forced to be used for unloading, due to the lack of reliable connection and support between the container and the open wagon, the container is prone to sliding or even falling off, which may cause serious safety hazards. Therefore, this mode of transportation cannot directly realize efficient and safe unloading operation through the existing tipper system.
[0004] Under current technological conditions, unloading open-top containers transported by rail typically requires additional auxiliary equipment. For example, a common method involves using cranes such as reach stackers to lift and unload the containers from the open wagons, then using specialized container tipping devices to dump the materials, and finally using reach stackers to return the empty containers to the open wagons. While this method accomplishes the unloading task, it has several drawbacks. First, the increased number of steps significantly prolongs operation time and reduces overall efficiency. Second, this method relies on additional lifting and tipping equipment, leading to a substantial increase in equipment investment costs and a corresponding increase in space requirements. Furthermore, frequent lifting and handling operations are not only inefficient but also increase operating costs and cause some environmental pollution due to equipment operation and material spillage. These problems place significant economic and operational pressure on enterprises in actual production.
[0005] In recent years, the use of rail transport and containerization for bulk materials has been encouraged to improve transportation efficiency and reduce environmental pollution. Against this backdrop, many companies have built or upgraded tippler systems to handle open-top containers transported in ordinary open wagons or dedicated flatbed wagons. However, how to achieve safe and efficient unloading of open-top containers transported in ordinary open wagons using tipplers has become a pressing technical challenge. The design and functionality of existing tippler systems are ill-suited to the needs of this type of transport, and there is a lack of specialized auxiliary devices for this scenario on the market. Therefore, developing a device compatible with existing tippler systems and capable of solving the unloading problem of containers transported in open wagons is not only of significant practical importance but also aligns with the development trend of railway transportation technology.
