Description

Technical Field

[0001] The utility model relates to the technical field of railway material excavators, and more specifically, to a fast unloading device for iron ore concentrate. Background Art

[0002] In the development of modern industry, iron ore concentrate powder is an important raw material for steel production, and its transportation and unloading are crucial. With the continuous expansion of industrial production scale and the increasing requirements for production efficiency, energy conservation and environmental protection, traditional train unloading equipment has gradually exposed many problems and shortcomings.

[0003] In the past, the commonly used unloading devices for train unloading operations included chain bucket unloaders and screw unloaders. There were widespread problems of slow unloading speed, large amount of ore left on the bottom of the carriage, and long time for subsequent manual cleaning of the bottom ore. This problem is particularly prominent in the rainy season. This not only leads to long stay time of railway vehicles in the station and high rental costs of national railway vehicles, but also seriously affects the efficiency of the entire production supply chain. In addition, due to the low efficiency of unloading, the labor cost and equipment operation and maintenance cost of cleaning the bottom ore of the carriage are also high. All of these have placed a heavy cost burden on enterprises.

[0004] Conventional unloading equipment has a complex structure and insufficient stability, and is prone to various faults. Problems such as wear of key components, failure of the electrical system, and damage to the mechanical transmission part frequently occur. Maintenance not only requires a large amount of manpower and material resources, but also causes long-term equipment downtime, seriously affecting the normal unloading work. Moreover, due to the uncertainty of equipment failure, it is difficult to formulate effective prevention and maintenance strategies in advance, further exacerbating the instability of production.

[0005] Conventional unloading devices perform poorly in terms of energy consumption and environmental protection. The high energy consumption operation mode not only increases the energy cost of the enterprise, but also does not meet the current social requirements for energy conservation and emission reduction. At the same time, the large amount of dust and noise generated during the unloading process has caused serious pollution to the indoor environment and threatened the health of the workers.

[0006] Therefore, in order to meet the rapid, efficient and energy-saving development needs of modern industry, especially to achieve safe and efficient unloading of iron ore concentrate powder in indoor environments, the development of a new train unloading device has become an urgent need for the development of the industry. Utility Model Content

[0007] The utility model provides an iron ore concentrate fast unloading device to solve the problems of low efficiency, great noise and dust pollution, and high operation and maintenance cost of existing conventional unloading equipment.

[0008] According to one aspect of the utility model, there is provided an iron ore concentrate fast unloading device, which is installed on both sides of a train rail, and comprises a cross beam, a connecting beam, a bottom beam and a slide, wherein the bottom beam is erected on both sides of the train rail, and the bottom beam is provided with running wheels adapted to the running rail, the connecting beam is installed on the bottom beam, the cross beam is erected on the top of the two connecting beams, a slewing mechanism is provided on the cross beam, and an excavator is installed on the slewing mechanism; the slide is arranged on one side of the running rail, and a material receiving funnel is arranged between the train rail and the running rail, and a belt conveyor is arranged at the bottom of the material receiving funnel.

[0013] Preferably, based on the above solution, the end surface of the base on which the side stopper wheel is mounted is connected to a rail clamp.

[0014] Preferably, based on the above scheme, the excavator comprises a main machine, an excavating arm and an electric control cabinet, the main machine is mounted on the slewing mechanism, and the excavating arm is mounted on the main machine.

[0015] The utility model discloses a fast unloading device for iron ore concentrate, which adopts the structure of a cross beam, a connecting beam and a bottom beam to form a stable support, and is integrally erected between train rails in combination with the running wheels on the bottom beam. When a conveying box on the train rails passes by, the movement of the running wheels on the bottom beam can be controlled to drive the excavator on the cross beam to move synchronously with the conveying box, so as to realize synchronous unloading. The unloading can be carried out quickly without affecting the conveying, and the unloading efficiency is high. At the same time, a receiving funnel is adopted to recover the raw materials dropped during unloading, so as to reduce the pollution to the indoor environment.

[0016] Compared with traditional fuel drive, the excavator adopts a fully electric drive system, which has many advantages such as high efficiency, energy saving and no noise. The excavation mechanism of the excavator, its boom length, bucket width and depth are tailored according to the working conditions. Different from the traditional crawler walking method, the new excavator adopts a track wheel walking mechanism, which has the characteristics of high walking operation precision, low resistance and energy saving.

[0017] At the same time, the connection method of the power cable is simplified, the fault points are reduced, and a supporting unloading room is built, and the excavator works indoors to ensure that the equipment is not affected by bad weather and reduce dust pollution to the surrounding environment. The busbar power supply solves the problem of conventional electric excavation cable dragging and entanglement, and can provide power continuously and stably.

[0018] The excavator travel rails are arranged in parallel with the railway carriage rails. The excavator moves forward and backward along the travel direction of the railway carriage on the rails and operates continuously. A steel grid and a slide are set on the ground on one side of the carriage, and a material receiving funnel and a belt conveyor are set below them. The steel grid is used to remove large pieces of debris in the material. The slide is used to prevent the material from being thrown during unloading. The material receiving funnel and the belt conveyor transport the material unloaded by the excavator to the downstream production unit. The above components are reasonably combined and matched to form an iron ore concentrate unloading device. The unloading device has many advantages such as high efficiency, energy saving, safety and environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS
