Box storage and transportation system

Abstract

The invention relates to mine and metallurgy storage and transportation equipment, in particular to a box storage and transportation system. The system comprises a box type material storage cabin and a material taking and conveying device, wherein the box type material storage cabin is provided with a feeding and discharging opening; and the material taking and conveying device enters and exits the box type material storage cabin through the feeding and discharging opening. The system transfers materials to subsequent transportation systems such as a mining truck, a belt conveyor, a scraper conveyor, a combination of the belt conveyor and the scraper conveyor, a lifting skip and the like, and can replace the mining truck and the like to directly transport the materials to a destination. The system has a simple structure, stable performance and a high spatial utilization rate, is conveniently and quickly maintained, improves the working efficiency of material storage and material discharging and can fully meet the requirement of an excavation field.

technical field [0001] The invention relates to mines and storage and transportation equipment, in particular to a box storage and transportation system. Background technique [0002] At present, in mineral mining and tunneling, there is a problem that the mining and tunneling speed is fast, but the transportation speed is slow, which leads to the problem that the two processes cannot run synchronously. Therefore, transportation has become the bottleneck of mineral mining and tunneling. The transportation equipment used in mines Most of them are mining vehicles. In practical applications, due to the small capacity and heavy weight of mining vehicles, they need to be used in large quantities, causing underground congestion, seriously reducing the overall production efficiency, and causing a large amount of resource consumption and waste.

[0002] At present, in mineral mining and tunneling, there is a problem that the mining and tunneling speed is fast, but the transportation speed is slow, which leads to the problem that the two processes cannot run synchronously. Therefore, transportation has become the bottleneck of mineral mining and tunneling. The transportation equipment used in mines Most of them are mining vehicles. In practical applications, due to the small capacity and heavy weight of mining vehicles, they need to be used in large quantities, causing underground congestion, seriously reducing the overall production efficiency, and causing a large amount of resource consumption and waste. In order to solve the above problems, the current general The shuttle car and the belt warehouse car are used. The application of these equipments alleviates the contradiction between fast mining and excavation speed and slow transportation speed and asynchronous speed. However, there are many deficiencies in actual use.

[0003] Although the shuttle car can store and transfer slag to a certain extent, due to the structural characteristics of the shuttle car itself, it has inevitable shortcomings: First, in order to reduce chain wear and prevent chain jumping, the chains on both sides of the bottom of the car Equipped with a protective plate and a cover plate, the effective volume of the shuttle car is greatly reduced, and the broken stones are easy to enter under the cover plate, resulting in a chain failure. Because the material is pressed on the chain, the handling of the fault is cumbersome and affects the work efficiency; the material and the scraper Pressed together on the bottom plate, sliding friction with the bottom plate, the friction force is large, and the power consumption is large; the scraper and the bottom plate are easy to wear, and the service life is short; The end is relatively low. In order to facilitate feeding to the equipment that receives materials at the rear, the discharge end is relatively high. In order to facilitate the overlapping of two shuttle cars, the loading end is relatively wide and the discharge end is relatively narrow. This structure makes the shuttle car bulky , the effective volume is not large, and the space utilization rate is low

Third, the drive device of the shuttle car itself increases the volume and weight of the shuttle car. The gangue or coal contained in the shuttle car often has a large water content and is often corrosive. The working environment of the drive device is poor, and it is difficult to operate and maintain. High, short service life; Fourth, the driving device needs to be connected to the power supply when the shuttle car is loaded or unloaded. Coal mines have very strict explosion-proof requirements, and the process of connecting the power supply is complicated and dangerous

[0004] The belt warehouse car is a recently developed storage and transfer equipment in China. It also has the above shortcomings. The lower part of the whole car is the transportation system, which occupies more than one-third of the space of the storage box. The rollers, idlers, belts, armor The belt and bracket mechanism greatly increases the weight of the car body, and the sealing between the car body baffle and the lower conveyor belt is difficult and the material leakage is serious, so there are problems such as small material storage space, many vulnerable parts, complicated and difficult maintenance, large power consumption, and serious pollution.

[0005] In summary, the currently commonly used shuttle cars and belt warehouse cars cannot better meet the needs of the excavation site
