Description

Technical Field

[0001] The invention relates to the technical field of mines, in particular to a ground gangue removal system. Background Art

[0002] Gangue is a stone mixed in the coal seam, containing a small amount of combustibles and not easy to burn, commonly known as "gangue". In the mining process, the crushed stone mined from the mine or mixed into the ore, the thin rock layer in the middle of the coal seam is called "interlayer stone", and the gangue pile on the mine surface is called "gangue mountain". Some gangue can be used as raw materials for building materials. The large-scale storage of gangue not only wastes land resources, but also causes spontaneous combustion, rain, mudification, etc., which seriously harms the environment. However, from the analysis of resource attributes, gangue is a valuable secondary resource. Its resource utilization is a necessary measure to prevent environmental disasters, and it is also one of the important tasks to achieve ecological civilization and circular economic development in the coal industry. With the further deepening of mine construction, the gangue of various underground excavation construction units is increasing. The original gangue discharge system is a temporary gangue discharge system with long transportation routes, complex operations, and many people.

[0026] A ground gangue discharge system comprises a high-position dumper 1, a trolley 4 and a track 7, wherein the high-position dumper 1 is provided at the left end of the track 7, a wheel-type car blocker 2 is provided at the front end of the high-position dumper 1, a material guiding mechanism is provided at the upper end of the high-position dumper 1, a trolley 4 is provided at the middle upper end of the track 7, a trolley 6 is provided on the inner side of the middle of the track 7, a hydraulic station 5 is provided at the right end of the track 7, a cushion block 8 is fixedly connected to the lower end surface of the track 7, and a lifting mechanism and a limiting mechanism are provided at the lower end of the high-position dumper 1.

[0027] The lifting mechanism includes a concrete wall 9, a first electric telescopic rod 12 and a partition 13. The top of the concrete wall 9 is provided with a partition 13. The first electric telescopic rod 12 is slidably connected to the inner side of the middle of the partition 13. The right side of the lower end of the first electric telescopic rod 12 is fixedly connected to the controller 11. The upper end surface of the partition 13 is fixedly connected to a pressure sensor 27. The inner side of the upper end of the pressure sensor 27 is connected to the position of the left end of the cross bar 25 through an opened slide groove 26. The middle of the cross bar 25 is connected to the second support rod 24 through a return spring 23. The right end of the cross bar 25 is fixedly connected to the lower end surface of the high-position tipping machine 1 through a limit rope 20 and a limit rope storage box 28. The limit rope storage box 2 8 is connected together by the telescopic spring 21 and the fixed rod 22, so that the gangue can be loaded on vehicles of different heights during use. Such a setting can adjust the lifting height of the high-position dumper 1 through the first electric telescopic rod 12 during use, which has a wider range of applications and is very practical; the pressure sensor 27 is arranged at the lower end of the high-position dumper 1, the bottom end of the second support rod 24 is fixedly connected to the partition 13, and the fixed rod 22 and the limit rope storage box 28 are slidably connected together. The pressure sensor 27 can be arranged to control the lifting of the high-position dumper 1 through the first electric telescopic rod 12. The lifting height of the vehicle machine 1 is limited. Such a setting can effectively improve the convenience and stability of the gangue loading process during use; the limiting mechanism includes a guide rod 10, a limiting bent plate 17 and a second electric telescopic rod 19. The top position of the guide rod 10 is fixedly connected to the lower end surface of the high-position dumper 1. The inner side of the guide rod 10 is connected to the limiting bent plate 17 through the opening of the limiting groove 16. The limiting bent plate 17 is connected to the first support rod 15 through the fixed shaft 14 and the eyelet 19. The bottom end of the first support rod 15 is fixedly connected to the partition 13. A second electric telescopic rod 18 is provided on the lower side of the end of the limiting bent plate 17 away from the limiting rod 10. The bottom end of the electric telescopic rod 18 is fixedly connected to the partition 13. When the high-position tipper 1 is ascending, the controller 11 controls the top end of the second electric telescopic rod 18 to move to the bottom end of the limit bend 17 while controlling the first electric telescopic rod 12 to ascend. When the first electric telescopic rod 12 descends, the second electric telescopic rod 18 is controlled to be recovered. In the process of the high-position tipper 1 ascending, the guide rod 10 and the limit bend 17 can prevent the first electric telescopic rod 12 from being suddenly damaged during the ascending process, thereby preventing the high-position tipper 1 from falling. Such a configuration has good stability during use.There are two guide rods 10, which are parallel to each other. The lower end of the guide rod 10 is slidably connected to the partition 13, and the guide rod 10 and the partition 13 are vertically arranged, which can play a positioning role in the process of lifting and lowering the high-position tipping machine 1, and effectively improve the stability of the high-position tipping machine 1 during the lifting and lowering process; the controller 11 and the first electric telescopic rod 12, the second electric telescopic rod 18, and the pressure sensor 27 are electrically connected together, and the electrical connection is more stable during use; the limit bend 17 is arranged in an "L" shape, and the position of the upper left side of the limit bend 17 is arc-shaped. The material guide mechanism includes a guide hopper 31, a guide hopper cover 3 and a sprayer 29. The front end of the guide hopper 31 is fixedly connected with a connecting plate 32 and a limiting rod 30. The connecting plate 32 is rotatably connected with the guide hopper cover 3 through a rotating shaft 33. The limiting rod 30 and the guide hopper cover 3 are slidably connected together. The upper end surface of the guide hopper cover 3 is fixedly connected with a sprayer 29. The guide hopper cover 3 can prevent the gangue from splashing. At the same time, the sprayer 29 can spray the gangue during loading to achieve the effect of dust reduction.

[0028] Working process: In the process of using a ground waste rock discharge system, first, the cart 4 loaded with waste rock is pushed to the upper end of the high-position dumper 1 by the cart pusher 6 from the auxiliary shaft side, and the cart 4 equipped with the high-position dumper 1 is pushed into the high-position dumper 1. The high-position dumper 1 supports the mine car by the swing arm, and the tilting cylinder pushes the swing arm to rotate around the arm axis, driving the cart 4 to flip 145°, and unloading the waste rock into the car parked in advance to achieve the purpose of unloading. When the swing arm approaches the end of the rotation, it is buffered by the reset cylinder. After unloading, the reset cylinder pushes the swing arm past the dead point, and then the swing arm is driven to fall by the tilting cylinder. The wheel-type car blocker 2 on the swing arm rotates by the torsion spring. When the swing arm is raised, the wheel-type car blocker 2 is closed. After the swing arm is reset When the wheel-blocking car blocker 2 is opened, the trolley 4 can be replaced. At the same time, when the gangue is loaded, the staff can load the gangue on the vehicle with a higher body as needed during actual use. When the trolley 4 is fixed to the inner side of the high-position dumper 1 through the wheel-blocking car blocker 2, the first electric telescopic rod 12 is controlled to push the high-position dumper 1 to move upward as a whole. During the movement, when the limit rope 20 in the limit rope storage box 28 is completely moved out of the limit rope storage box 28, the limit rope 20 will pull the position of the right end of the cross bar 25 to move upward. At this time, the position of the left end of the cross bar 25 will move downward and squeeze the pressure sensor 27. At this time, the pressure sensor 27 will transmit the signal to the transmission controller 11 after being squeezed and control the first electric telescopic rod 12 to move upward. The retracting rod 12 stops working. During the use of such a setting, the upward distance of the high-position tipping machine 1 can be controlled by setting limit ropes 20 of different lengths. When the high-position tipping machine 1 moves downward, when the position of the lower end surface of the high-position tipping machine 1 contacts the position of the upper end of the pressure sensor 27, the pressure sensor 27 will transmit a signal to the controller 11. At this time, the controller 11 will control the first electric telescopic rod 12 to stop working. During the use of such a setting, the track 7 set on the inner side of the high-position tipping machine 1 can be aligned with the main track, and when the high-position tipping machine 1 is rising, the controller 11 will control the position of the top end of the second electric telescopic rod 18 to move to the position of the bottom end of the limit bend plate 17 during the process of controlling the rise of the first electric telescopic rod 12. During the descent of the first electric telescopic rod 12, the second electric telescopic rod 18 is controlled to be recovered. In the process of the high-position tipping machine 1 rising, the guide rod 10 and the limit bending plate 17 can prevent the first electric telescopic rod 12 from being suddenly damaged during the rising process, thereby causing the high-position tipping machine 1 to fall. The high-position tipping machine 1 has good stability during use. When the high-position tipping machine 1 controls the cart 4 to pour the gangue into the vehicle through the guide hopper 31, the guide hopper upper cover 3 can prevent the gangue from splashing. At the same time, the sprayer 29 can be used to spray the gangue during the loading process to achieve the effect of dust reduction. Such a setting can effectively improve the quality of the working environment during the loading process during use.It has good practical value and is worthy of wide promotion and use.
