Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Taking the bottom-side dump car as an example in the present invention, the entire unloading process is completed by the cooperation of the unloading curved rail 600 and the riding wheel structure 500 with the car 700 in the chamber 400. Fig. 1-3 schematically illustrate the specific structure of the underground mine unloading station of the present invention.
As shown in fig. 1 to 3, the present invention provides an underground mine unloading station, comprising: the running rail 100 of the mine car 700, the discharge chute 200 located below the running rail 100, and the discharge spout 300 located at the lower end of the discharge chute 200. By improving the structure of the unloading chute 200 in the unloading station, the invention avoids the problem that the unloading chute 200 is damaged due to the direct impact of ore on the unloading chute 200, ensures the safety and reliability of the unloading station and reduces the consumption of the lining plate 241 in the unloading chute 200.
The discharge chute 200 comprises: a side upper base 210 under both sides of the running rail 100, and a side upper base on the vehicle entrance sideA first sloped sidewall and a second sloped sidewall 240 on the exit side; the first and second sloped side walls 240 slope downwardly to the unloading chute 300; the first slope type side wall protrudes from the inner side to the outer side to form a buffer pit 232, and waste rocks are filled in the buffer pit 232. Wherein, the side wall foundation 210 is a concrete foundation. At 6m3For example, the first and second sloped sidewalls 240 may slope downwardly at an angle of about 46 degrees. The length of the upper opening (in the direction of the running rail 100) of the discharge chute 200 can be 24800 mm. The distance from the upper opening of the discharge chute 200 to the top of the discharge chute 300 may be 10719 mm.
The buffer pit 232 is located in the lower portion of the discharge chute 200, thus solving the problem of repeated impact of ore on the structure below the discharge chute 200. The buffer pit 232 may be formed by the first sloped sidewall protruding from the inner side to the outer side by an included angle or an arc shape.
The included angle may be one of an acute angle, a right angle, and an obtuse angle. Preferably, the included angle is a right angle or an obtuse angle, and the buffer pit 232 in the form of the included angle is more convenient and faster in operation. More preferably, the first sloped side wall protrudes from the inner side to the outer side at a right angle to form a buffer pit 232, and the buffer pit 232 in the form of a right angle facilitates filling of waste rocks and can effectively buffer the discharge chute 200. The distance between the outermost side of the buffer pit 232 and the centre line of the discharge spout 300 may be 10400 mm.
The arc can be a major arc or a minor arc, and can be determined according to the ore discharge amount, for example, when the ore discharge amount is large, the arc can be set as the major arc to increase the area for filling the waste rocks; when the ore discharge amount is small, a minor arc may be set. The arc-shaped buffer pit 232 can avoid dead angles of the unloading chute 200, and can further ensure that the inner side and the outer side of the side wall are firm.
In the present invention, the buffer pit 232 divides the first sloped sidewall into two inclined segments, including: the first inclined section 231 that is higher than the buffer pit 232 and the second inclined section 233 that is less than the buffer pit 232 and is connected with the uninstallation chute 300, the ore falls on the barren rock of buffer pit 232, after the buffering through the second inclined section 233 landing to the download chute to avoided the ore to the direct impact of uninstallation chute 200 inner wall. Preferably, the connection between the buffer pit 232 and the first and second inclined sections 231, 233 is also chamfered to facilitate the sliding of ore to the discharge spout 300, and the chamfer also improves the robustness of the discharge chute 200. Alternatively, in order to further reduce the impact of the ore on the first sloped inner wall and avoid the collapse phenomenon at the corners of the buffer pit 232, a reinforcing layer may be further disposed at the connection portion of the buffer pit 232 and the first sloped section 231 and the second sloped section 233, and specifically, the reinforcing layer may extend from the edge of the buffer pit 232 to the first sloped section 231 or the second sloped section 233. The material of the reinforcing layer is not limited, and may be the same as the material of the lining plate 241, may be a wear-resistant material, and may be a concrete structure layer.
In an alternative embodiment, the side foundation 210 may also be flared outwardly from the inside of the discharge chute 200 to form a buffer zone 211. The specific structure of the buffer region 211 is not particularly limited, and may be a long strip shape or the like as long as it can perform a buffering function. The buffer zone 211 is located in the upper part of the discharge chute 200, thus addressing the repeated impacts of the ore on the superstructure of the discharge chute 200.
Further, the buffer area 211 is located on the side wall base 210 on the vehicle entering side, for example, on the left side of the running track 100 as shown in fig. 2, and is arranged along the running track 100, and according to the ore unloading angle, a first end of the buffer area 211 can be aligned with a first end of the buffer pit 232; for better cushioning of the discharge chute 200, the second end of the buffering area 211 is arranged beyond the discharge spout 300, as shown in fig. 1, the end of the second end of the buffering area 211 is located right above the second sloped side wall 240, and the distance from the second end of the buffering area 211 to the center line of the discharge spout 300 may be 2500 mm. Preferably, a wear-resistant liner 241 may also be provided on the highwall foundation 210 to reinforce the highwall foundation 210.
In the present invention, a wear-resistant liner 241 may be provided on the second sloped side wall 240 to reinforce the side. As the buffer pit 232 is arranged on the first slope-type side wall, the lining plate 241 arranged on the side wall can be omitted, so that the engineering cost is reduced, and through calculation, the material cost of each unloading station can be saved by about 10 ten thousand yuan due to the reduction of the using amount of the lining plate 241.
According to the embodiment, the buffer area 211 is arranged at the side wall base 210, so that the impact of the ore on the upper structure of the unloading chute 200 is avoided, the buffer pit 232 filled with waste rocks is arranged on the first slope side wall, the impact of the ore on the lower structure of the unloading chute 200 is avoided, the quality of the structure of the unloading chute 200 is guaranteed, the safety and reliability of the unloading station are improved, the normal unloading and transportation of the ore are guaranteed, and the engineering cost is saved.
The description of the present invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to practitioners skilled in this art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
