Problems solved by technology

[0002] In recent years, many underground auxiliary transportation devices in coal mines have been continuously upgraded. Mine trackless rubber-tyred vehicles are a kind of auxiliary transportation vehicles used in underground mines. In view of their fast and efficient working methods and good economic benefits, this trackless rubber-tyred vehicles are used in It is more and more widely used in modern coal mines. However, the use of trackless rubber-tyred vehicles has brought about the problem that the original underground roadway is not suitable for the transportation conditions of trackless rubber-tyred vehicles. One of them is that the main roadways under some mines use water ditches. Drainage, the load-bearing capacity of the original cement ditch cover is not enough to meet the transport support of trackless rubber-tyred vehicles, and the width of the roadway after removing the width of the ditch cannot meet the transportation support of rubber-tyred vehicles

Embodiment 1

[0029] Such as figure 1 and 5 As shown, the ditch cover provided in this specific embodiment to support the underground transportation of trackless rubber-tyred vehicles includes a plurality of fixed cover groups 1 and a plurality of movable cover groups 2, and the fixed cover group 1 and the movable cover group 2 The number to be set is determined according to the length of the ditch in the reconstructed roadway. The fixed cover plate set 1 includes a plurality of cover plates 3 , and the movable cover plate set 2 includes several cover plates 3 .

[0030] Such as Figure 2-4 As shown, the cover plate 3 is formed by connecting a plurality of ground rails 31 side by side. The ground rails 31 are the ground rails 31 disassembled in the trackless transformation of underground auxiliary transportation. The upper rail surface is difficult to be welded and connected, so the lower rail of the ground rail track 31 faces up as the upper surface of the cover plate 3, and the multipl...

Embodiment 2

[0041] The ditch cover plate supporting the underground transportation of trackless rubber-tyred vehicles in Example 1 is applied to the reconstruction of the underground track roadway of Jining No. 2 Coal Mine. The length of the roadway to be transformed is 300m, and the width of this roadway cannot meet the requirements of trackless rubber-tyred vehicle transportation. Requirements, such as according to the usual transformation method, after removing the width of the underground ditch, it is necessary to increase the width of the roadway by 1m, the height by 3m, and the cubic volume of the brush side to be 900m 3 , each labor cost is 145 yuan, and it takes about 4 months to rebuild a 300m roadway. There are 7 people in each shift, and a total labor cost of 365,000 yuan is required. The invented cover plate can be laid directly on the top of the underground ditch after preliminary processing and welding, and its load-bearing capacity is enough to meet the transportation of tra...

Embodiment 3

[0043] The ditch cover supporting the underground transportation of trackless rubber-tyred vehicles in Example 1 is applied to the transformation of another track roadway in Jining No. 2 Coal Mine. For wheeler transportation requirements, after removing the width of the underground ditch, it is necessary to increase the width of the roadway by 1m, the height by 3m, and the cubic volume of the brush side to 600m 3 , each labor cost is 145 yuan, 200m roadway reconstruction takes about 3 months, 7 people per shift, a total labor cost of 274,000 yuan is required, and material costs for anchor rods, anchoring agents, steel strips, etc. consume about 13,000 yuan. The invented cover plate can be laid directly on the top of the underground ditch after preliminary processing and welding, and its load-bearing capacity is enough to meet the transportation of trackless rubber-tyred vehicles. Using the ditch cover plate of the present invention to transform the roadway does not need to incr...

Abstract

The invention discloses a ditch cover plate for supporting underground transportation of a railless rubber-tyred vehicle. The ditch cover plate for supporting underground transportation of the railless rubber-tyred vehicle comprises a plurality of fixed cover plate sets and a plurality of movable cover plate sets; each fixed cover plate set comprises a plurality of cover plates, each movable coverplate set comprises a plurality of cover plates; the fixed cover plate sets and the movable cover plate sets are arranged at intervals along the length direction of a ditch; the movable cover plate sets are detachably arranged above the underground ditch and are used for cleaning the underground ditch after being disassembled; each cover plate is formed by connecting a plurality of ground rail tracks side by side; and the ground rail tracks are ground rail tracks disassembled in underground auxiliary transportation railless transformation. The ditch cover plate is formed by transforming the waste ground rail tracks, waste resources are well utilized while load bearing of the ditch cover plate is guaranteed, waste is turned into wealth, the transformation process is simplified, the transformation time and capital investment in transformation are greatly saved, waste ground rail track accumulation is avoided, and the transformation time is saved.
