Description

Bulk material direct-unloading type car loader

Technical Field

The invention relates to the technical field of bulk cargo transfer equipment, in particular to a bulk cargo material direct-unloading type car loader.

Background

Bulk materials such as coal, iron ore and the like are important raw materials for economic development in China, and the bulk materials are usually firstly stacked in some transfer centers and then transported to various places by railways. In this process, bulk cargo unloaded at the transfer center needs to be loaded into the railway cars, and the existing wharfs have several common bulk cargo material loading modes:

(1) the dumper feeding and loading are matched: the dump truck conveys the bulk cargo materials from the storage yard to the side of the train line for temporary storage, and the loader shovels the materials and dumps the materials into the train carriage. The loading mode has the advantages that the equipment and the operation mode are simple and convenient, and the requirements on the site and the investment are low. But the defect is obvious, the loading mode adopts an intermittent relay type loading mode, and compared with other loading modes, the loading efficiency is lower. In addition, the dust pollution is serious in the operation process, and the goods damage rate is high.

(2) Directly dumping and loading the fixed platform dump truck: a simple special loading platform is built beside a transportation railway line, the height of the platform is basically flush with the top of the carriage, and the dumper is driven to the platform to directly dump materials into the carriage. The loading mode has the advantages that the middle transfer link is removed, the dump truck is directly used for supplying materials to the carriage, the middle goods loss is reduced, and the transfer efficiency is improved. But also has the defect that the platform is fixed, the train matching platform needs to be pulled, and the driver needs to adjust the dumper matching platform, so that the equipment cost and the time cost are inevitably increased in the process, and the transfer efficiency is reduced.

(3) The belt conveyor and the movable car loader are matched for loading, wherein the belt conveyor conveys materials to a material receiving point on the movable car loader, and the cantilever belt conveyor on the movable car loader loads the materials into a train carriage. The loading mode has the advantages of high efficiency, high precision, environmental protection, good economy and the like, but in use, the belt type transmission mechanism is too long in length, too large in occupied area, seriously occupies the wharf operation area, is easy to interfere with other equipment, and is difficult to popularize and use in small and medium-sized wharfs.

(4) And (3) matching and loading the system belt conveyor and the loading building: the system belt conveyor conveys bulk materials from a storage yard to a loading building, the loading building loads the bulk materials into a train carriage, the loading mode is used as a semi-automatic train loading mode, solid materials can be quickly and continuously loaded into a train advancing at a certain speed according to a preset loading amount value, the loading efficiency is high, and the pollution is small. However, the loading device is high in construction and maintenance cost and high in energy consumption.

The four bulk cargo loading modes have respective advantages and disadvantages, are also applied to the bulk cargo conveying process of a wharf, and cannot bear the cost of building and using a system belt conveyor and supporting equipment thereof and the space for accommodating belt pulleys for medium and small transit centers with common size and economic strength. Some small and medium-sized transit centers on the market need a bulk cargo conveying device with excellent comprehensive performance.
