Upper curved rail side pressure bottom unloading mine car and using method

Abstract

The invention discloses a top curved rail side pressing type bottom dumping car and a use method and belongs to the field of underground coal mine car transporting devices. Technical problems to be solved are that an existing bottom dumping car is not simply structured, is inconvenient to load and unload and cannot be used for various mineral conditions. A technical scheme adopted to solve the technical problems is that the top curved rail side pressing type bottom dumping car comprises a compartment; a clamping mechanism is arranged above the compartment; the compartment is divided into a left box body and a right box body; running wheels are arranged on the two sides of the bottom of the left box body and the two sides of the bottom of the right box body; and curved rails are arranged above the clamping mechanism. When the car passes through the curved rails, the clamping device opens the compartment to perform coal loading and unloading operations; and after the car passes through the curved rails, the left box body and the right box body are automatically closed; and therefore, the use is convenient. The top curved rail side pressing type bottom dumping car can be widely applied to the field of underground transportation.

Description

technical field [0001] The invention discloses an upper curved rail side pressure bottom unloading mine car and a use method thereof, belonging to the technical field of underground mine car transportation devices in coal mines. Background technique [0002] Coal is China's main energy source and an important chemical raw material. The two major contributions of the coal industry to the country, that is, the contribution to the national economy and the contribution to providing a large number of employment opportunities for the society, are destined to play an important role in China's national economic and social development. This status will not change for quite a long period of time in the future. This status is determined by the resource characteristics of China's energy resources and the level of economic development. During this period, coal scientific and technological workers created and practiced layered mining, release Top-coal mining, large mining height and full-he...

AI Technical Summary

Problems solved by technology

[0004] Mining cars play an indispensable role as a traditional and reliable mode of transportation. At present, the types of mining cars commonly used in coal mine production mainly include fixed mining cars, bottom dumping mining cars and side dumping mining cars. The mine car is simple in structure, reliable in use, small in wagon coefficient, large in volume, sturdy and durable, and easy to maintain, but it needs special unloading equipment for unloading, and the unloading efficiency is low. It is relatively large and the structure of the unloading station is complex. It is suitable for mines with adhesive properties, large annual output and stable surrounding rocks. However, the movable side wall of the side unloading mine car is prone to powder leakage, and the mine car is required to have a fixed direction during loading and unloading, so it is not suitable It is used in mines with a lot of powder ore, heavy minerals and high water content
