U-shaped fixed carriage type mine car

Abstract

The invention discloses a U-shaped fixed carriage type mine car and relates to the field of mine car equipment. The mine car comprises a carriage, car frames, open type wheel sets, an anti-falling plug pin, a three-ring chain and handles. The carriage body is composed of an anti-collision layer, a buffer layer, an adhesion layer and an anti-corrosion layer. The anti-collision layer is the outermost layer of the carriage; the buffer layer is glued and adhered to the inner wall of the anti-collision layer; the adhesion layer adheres to the buffer layer and the anti-corrosion layer; the car frames are fixed at the bottom of the carriage through a plurality of bolts; and the number of the car frames is two, the open wheel sets are fixed to the two sides of the car frames through bolts, the number of the open wheel sets is four, the anti-falling plug pin is installed on a connecting base connected with the carriage, the three-ring chain is placed on the connecting base and connected to theanti-falling plug pin in a sleeving mode, and the four handles are fixed to a front side and a rear side of the carriage through screws. By adopting a multi-layer carriage wall structure, a stainlesssteel inner wall can effectively prevent a carriage inner wall from being corroded and is convenient to clean, the adhesion layer and the buffer layer can reduce impact on the stainless steel inner wall and prolong a service life of the stainless steel inner wall, and a cast iron protective layer can protect the inner wall from being impacted by an external force and improve durability of the minecar.

Description

technical field [0001] The invention relates to a U-shaped fixed carriage type mine car, and relates to the field of mine car equipment. Background technique [0002] Mining cars are narrow-gauge railway transportation vehicles for transporting bulk materials such as coal, ore and waste rocks in mines. Generally, they must be pulled by locomotives or winches. Mining cars are divided into fixed mining cars (material cars, flat car), tipping mine car, single-side curved track side unloading mine car, bottom (side) unloading mine car and shuttle mine car, a total of 5 categories. Transportation is the largest and most widely used transportation equipment in coal mines. The commonly used gauges are 600, 762, and 900mm. Standard or narrow-gauge railway vehicles for transporting bulk materials such as ore, waste rock, and coal in mines are generally Pulled by a locomotive or winch, in addition to the mine carts for transporting bulk materials, mining vehicles also include flatbed...

Problems solved by technology

[0003] In the current coal mine or other ore mining, due to the needs of actual use, the fixed mine car is a kind of mine car with high frequency of use. By using the fixed mine car to transport raw materials, due to different application scenarios, the mine car transported The raw materials are also different. Due to the high frequency of use of the mine car, the wear of the inner wall of the mine car is generally more serious, especially when transporting some relatively sharp mine cars and corrosive materials, the wear of the inner wall of the mine car is more serious. Serious, and because the mine car box is usually a cast iron structure, it is more likely to be corroded. In addition, because the ore raw materials will drop waste residue during transportation, the usual cleaning is to clean the mine car with water, and the residual moisture will also accelerate the cast iron mine. Oxidation corrosion of the car, the impact of the mine car is very obvious. After long-term wear and corrosion, the box of the mine car is prone to damage, which affects the normal use of the mine car
