Description

Technical Field

[0001] The utility model relates to the field of coal mining equipment, in particular to a rain-proof and water-draining shed for coal mine roadways. Background Art

[0002] As the main source of energy resources, coal mines play an important role in social and economic development. During coal mining operations, underground coal miners face many safety risks. Especially with the increase in the tunneling depth, geological water seepage or surface water penetration often occurs in underground coal mines, causing large-area water spraying on the top of underground roadways, resulting in a poor working environment in the roadways. Coal miners and equipment are often wetted by the water spraying on the top of the mine roadways. Over time, this will lead to equipment corrosion, and in severe cases, it will even cause electric leakage accidents, threatening the lives of coal miners. Therefore, effectively controlling the water spraying problem in underground coal mine roadways is an important measure to ensure the safe production of coal mines. Content of the Utility Model

[0003] The utility model provides a rain-proof and water-draining shed for coal mine roadways. By installing the rain-proof and water-draining shed on the top of the coal mine roadway, the water spraying is guided into the roadway drainage ditch, effectively controlling the water spraying problem in the underground coal mine roadway.

[0004] To achieve its purpose, the utility model adopts the following technical solutions:

[0005] A rain-proof and water-draining shed for coal mine roadways, wherein hollow anchor bolts are vertically arranged at the inner top of the coal mine roadway. The rain-proof and water-draining shed includes a water-draining shed body. Several water-draining shed skeletons are arranged inside the water-draining shed body, and several water-draining shed skeletons at the center of the water-draining shed body are connected to the hollow anchor bolts.

[0006] Further, the water-draining shed skeleton includes a main skeleton and a sub-skeleton connected to each other. A first through hole is arranged at the center of the main skeleton. At least two connecting rings are sleeved on the main skeleton. First stoppers are symmetrically arranged at both ends of the top of the main skeleton. The two sub-skeletons pass through the connecting rings and are symmetrically sleeved at the bottom of the main skeleton. A second stopper is arranged at one end of the bottom of the sub-skeleton close to the main skeleton. A second through hole is arranged on the side of the sub-skeleton far from the second stopper.

[0007] Further, the distance between adjacent water-draining shed skeletons is 0.8 - 1 m.

[0008] Further, the free end of the hollow anchor bolt passes through the first through hole of the water-draining shed skeleton at the center of the water-draining shed body and is fastened with a nut.

[0009] Further, an expansion bolt is inserted into the second through hole to fasten the water-draining shed skeleton and the water-draining shed body to the inner wall of the coal mine roadway.

[0010] Further, the inner diameter of the first through hole is 2 - 4 mm larger than the outer diameter of the hollow anchor bolt.

[0011] Furthermore, the thickness of the hydrophobic shed body is 0.4 - 0.6 mm.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. Through the anti - splash hydrophobic shed provided by the present utility model, the splash water is guided into the floor drain of the roadway, preventing coal miners and equipment from being wet by mine water, preventing equipment corrosion and electric leakage accidents, and ensuring the life safety of coal miners.

Detailed Embodiments

[0019] The present utility model will be further described below with reference to the drawings:

[0020] As Figures 1 - 3 shown, the present utility model is an anti - splash hydrophobic shed for coal mine roadways. A hollow bolt is vertically provided at the inner top of the coal mine roadway 1. The hollow bolt selects a T - type threaded self - advancing hollow bolt with a length of 0.5 m and an outer diameter of φ25 mm. The anti - splash hydrophobic shed includes a hydrophobic shed body 3 with a thickness of 0.4 mm, and the size of the hydrophobic shed body 3 can be cut according to the seepage area and the top arc length of the coal mine roadway 1.

[0021] Inside the hydrophobic shed body 3, there are multiple hydrophobic shed skeletons 2 made of flat iron with a length of 3 m and a width of 40 mm hinged. The spacing between adjacent hydrophobic shed skeletons 2 is 1 m. The hydrophobic shed skeleton 2 includes a connected main skeleton 7 and a sub-skeleton 5. At the center of the main skeleton 7, there is a first through-hole 10 with an inner diameter of φ28 mm. When erecting the hydrophobic shed body 3, the free end of the hollow bolt is passed through the first through-hole 10 of the hydrophobic shed skeleton 2 at the center of the hydrophobic shed body 3 and then fastened with a nut. Two steel connecting rings 8 are sleeved in parallel on the main skeleton 7, and first stoppers 9 are symmetrically welded at both ends of the top of the main skeleton 7. One end of the two sub-skeletons 5 passes through the connecting rings 8 and is symmetrically sleeved at the bottom of the main skeleton 7. A second stopper 6 is welded at one end of the sub-skeleton 5 close to the main skeleton 7. A second through-hole 11 with an inner diameter of φ14 mm is provided at a position 0.5 m away from the end of the sub-skeleton 5 on the side away from the second stopper 6 of the sub-skeleton 5. The hydrophobic shed skeleton 2 and the hydrophobic shed body 3 are fastened to the inner wall of the coal mine roadway 1 by inserting an expansion bolt 4 into the second through-hole 11. The connection method between the hydrophobic shed body 3 and the hydrophobic shed skeleton 2 is the same as the connection method between an umbrella and its ribs. When the hydrophobic shed body 3 is unfolded, the length of the hydrophobic shed skeleton 2 can freely contract and extend according to the arc length of the arch top of the coal mine roadway 1. When extended to the limit, the connecting rings 8 block the first stoppers 9 and the second stoppers 6 at the ends of the main skeleton 7 and the sub-skeleton 5 to prevent falling off, realizing the adaptive adjustment of the hydrophobic shed skeleton 2, so that the anti-drenching hydrophobic shed is applicable to the waterproof work of coal mine roadways 1 of different specifications.

[0022] During use, first, a T-shaped threaded self-advancing hollow bolt is vertically installed and fixed at the center of the arch top of the coal mine roadway 1 in the water spraying section. Then, the first through-hole 10 of the hydrophobic shed skeleton 2 at the center of the hydrophobic shed body 3 is sleeved on the free end of the hollow bolt. The hollow bolt is firmly fixed at the arch top of the roadway with a plug, a backing plate and a hexagonal nut at the end of the free end of the hollow bolt, so that the hydrophobic shed skeleton 2 and the hydrophobic shed body 3 are closely fixed on the top of the coal mine roadway 1. Finally, a φ10 mm expansion bolt is inserted into the second through-holes 11 on the two sub-skeletons 5, and the hydrophobic shed skeleton 2 and the hydrophobic shed body 3 are pressed and fixed on the inner wall of the coal mine roadway 1, thereby guiding the water spraying to the drainage ditch of the coal mine roadway 1 and effectively solving the problem of water spraying.
