A coal mine underground mining support device

Abstract

This utility model relates to the field of mining support technology and proposes a coal mine underground mining support device, including a roof plate. A support frame is provided above the top of the roof plate, and a plurality of drainage holes are equidistantly opened on the top end face of the support frame. In this coal mine underground mining support device, water seeping from the channel can flow into a filter cylinder through the drainage holes. The filter cylinder can filter the water. The water seeps out through the filter holes of the filter cylinder and, guided by the arc plate, flows into the guide channel. The guide channel then guides the water to the drain outlet and discharges it. The coal slag and other impurities filtered from the water are temporarily stored in the filter cylinder. By pushing the base, the vertical rod can be moved upward, and the spring is squeezed by the support plate. The force is transmitted to the support through the support plate and the support rod, which can lift the arc plate and move the top of the rod to the drainage hole, thereby pushing out the filtered coal slag and other impurities, preventing the coal slag and other impurities from clogging the filter cylinder and affecting the drainage effect.

Description

Technical Field

[0001] This utility model relates to the field of mining support technology, specifically to a coal mine underground mining support device. Background Technology

[0002] Underground mining is a type of coal mining that contrasts with open-pit mining. It is suitable for coal deposits that are buried at greater depths. In my country, about 90% of coal is mined underground. Underground mining is technically more challenging than open-pit mining and is subject to greater constraints from environmental and equipment conditions. Coal deposits are typically layered, widely distributed, and have large reserves. However, mining operations are often threatened by hazards such as water, fire, and gas, and therefore have unique technical characteristics. Underground coal mining requires support systems to prevent roof collapse and rock strata collapse, ensuring the safety of the working space.

[0003] A search revealed an existing technology (publication number: CN211819470U) for a coal mine underground mining support device. The technology describes a device that "includes a water-blocking component and multiple support frames evenly arranged on the bottom surface of the water-blocking component. The water-blocking component includes a water collection trough, with an arc-shaped protective net fixed to its top. Water outlets are symmetrically arranged on both sides of the bottom surface. Two inclined water guide plates are symmetrically arranged and rotatably connected to the bottom surface of the water collection trough. The water guide plates have a hollow structure with an open top and a water guide pipe connected to the bottom. The support frames include two symmetrically arranged support rods, with a top rod vertically fixed to the inner side of the top of each support rod. An adjusting support component is provided between the corresponding top rods on both sides, and the bottom surface of the water guide plate contacts the top of the corresponding support rod." However, during use, coal slag and other debris can fall into the water collection trough along with the water, easily clogging the water outlets and affecting drainage. Therefore, designing a coal mine underground mining support device is essential. Utility Model Content

[0004] The purpose of this utility model is to provide a support device for underground coal mining, which solves the problem in related technologies where coal slag and other debris fall off during use and enter the water collection tank with water, easily clogging the water outlet and thus affecting the drainage effect.

[0005] The technical solution of this utility model is as follows:

[0006] A coal mine underground mining support device includes a roof plate. A support frame is provided above the top of the roof plate, and a plurality of drainage holes are equally spaced on the top end face of the support frame. Filter cylinders are screwed to the bottom of the drainage holes. An arc plate is provided on the inner top of the support frame, and a plurality of top rods are equally spaced welded to the top end face of the arc plate. One top end of each top rod is inserted into the bottom of the filter cylinder. A support is screwed to the center of the bottom of the arc plate, and support rods are screwed to the bottom perimeter of the support. A support plate is provided below the bottom of the support frame, and one bottom end of each support rod passes through the support frame and is screwed to the top of the support plate. A spring is screwed to the top end face of the support plate, and the top of the spring is screwed to the bottom of the support frame. A vertical rod is screwed to the bottom end face of the support plate, and a limiting frame is fitted on the vertical rod. The bottom of the limiting frame is welded to the top end face of the roof plate. One bottom end of the vertical rod passes through the roof plate and is screwed to a base.

[0007] Preferably, the top of the support frame is arc-shaped, and the bottom of the base is glued with a rubber pad.

[0008] Preferably, the inner wall of the support frame is provided with guide grooves on both sides, and the outer walls on both sides of the support frame are provided with drain outlets, and the drain outlets are connected to the guide grooves. A guide plate is screwed to the bottom of the drain outlet.

[0009] Preferably, several dampers are screwed to both sides of the top plate, and the telescopic ends of the dampers are screwed to the bottom end face of the support frame.

[0010] Preferably, a base plate is provided below the bottom of the top plate, and pillars are welded to the top four sides of the base plate. A first slider is slidably installed inside the pillar, and a column is welded to the top end face of the first slider. One top end of the column is screwed to the bottom end face of the top plate.

[0011] Preferably, the outer wall of the support column is welded with a slide rail, and a second slider is slidably installed inside the slide rail. A connecting rod is welded to the top end face of the second slider, and the other end of the connecting rod is welded and fixed to the outer wall of the support column. A plurality of limiting holes are equally spaced on the support column. An insert tube is welded to the second slider, and an insert rod is inserted into the inside of the insert tube. One end of the insert rod is inserted into the limiting hole.

[0012] Preferably, a connecting plate is screwed between the other ends of the two insertion rods, and a handle is welded between the two insertion tubes, with a pair of telescopic rods screwed onto the handle. The telescopic ends of the telescopic rods are screwed and fixed to the connecting plate.

[0013] Preferably, the bottom of the base plate is screwed with movable seats around its perimeter, and a hidden groove is provided at one end of the bottom of the movable seat. A ground-inserting cone is installed inside the hidden groove via a rotating shaft, and a roller is provided at the other end of the bottom of the movable seat.

[0014] The beneficial effects of this utility model are:

[0015] 1. Water seeping from the channel through the drain hole flows into the filter cartridge, which filters the water. The water seeps out through the filter holes and, guided by the arc plate, flows into the guide channel. The guide channel then guides the water to the drain outlet for discharge. Cinders and other impurities filtered out of the water are temporarily stored inside the filter cartridge. Pushing the base moves the vertical rod upward, and the support plate compresses the spring. The force is transmitted to the support through the support plate and the support rod, lifting the arc plate and moving the top of the push rod to the drain hole, thus pushing out the filtered cinders and other impurities. This prevents cinders and other impurities from clogging the filter cartridge and affecting drainage. Releasing the base causes the spring to apply outward tension, moving the support plate downward and allowing it to fit against the top of the limit frame. This method allows for periodic cleaning of cinders and other impurities inside the filter cartridge, preventing blockages and ensuring proper drainage.

[0016] 2. The equipment can be moved by the rollers. By rotating the ground-inserting cone to make it perpendicular to the ground and inserting it into the ground, the position of the equipment can be fixed to prevent it from moving during mining. Pushing the connecting plate outward can move the insert rod out of the limiting hole. Pulling or pushing the handle down can use the second slider to adjust the height of the support frame, so that the top of the support frame is in contact with the top wall of the mining channel. Pulling the connecting plate to insert the insert rod into the limiting hole can fix the position of the support frame, thereby forming a support effect. The damper provides buffering for the support frame. Attached Figure Description

[0025] like Figure 1-5As shown, this embodiment proposes a coal mine underground mining support device, including a roof plate 1. A support frame 2 is provided above the top of the roof plate 1, and a plurality of drainage holes 3 are equally spaced on the top end face of the support frame 2. A filter cylinder 4 is screwed to the bottom of the drainage holes 3.

A vertical rod 11 is screwed to the bottom end face of the support plate 9, and a limiting frame 12 is fitted on the vertical rod 11. The bottom of the limiting frame 12 is welded and fixed to the top end face of the top plate 1. One end of the bottom of the vertical rod 11 passes through the top plate 1 and is screwed to a base 13. The top of the support frame 2 is arc-shaped. A rubber pad 14 is glued to the bottom of the base 13. Both sides of the bottom of the inner wall of the support frame 2 are provided with guide grooves 15. Both sides of the outer wall of the support frame 2 are provided with drain outlets 16, and the drain outlets 16 are connected to the guide grooves 15. A guide plate 17 is screwed to the bottom of the drain outlet 16. Water entering the support frame 2 can be guided to the drain outlet 16 and discharged through the guide grooves 15. The drained water can be guided outward by the guide plate 17. The top of the top plate 1 Several dampers 18 are screwed onto both sides, and the telescopic ends of the dampers 18 are screwed and fixed to the bottom end face of the support frame 2. The dampers 18 provide buffering for the support frame 2. A base plate 19 is provided below the bottom of the top plate 1, and support columns 20 are welded to the top four sides of the base plate 19. A first slider 21 is slidably installed inside the support column 20, and a column 22 is welded to the top end face of the first slider 21. One top end of the column 22 is screwed and fixed to the bottom end face of the top plate 1. The height of the top plate 1 can be adjusted by using the first slider 21 and the column 22. A slide rail 23 is welded to the outer wall of the support column 20, and a second slider 24 is slidably installed inside the slide rail 23. A connecting rod 25 is welded to the top end face of the second slider 24, and the other end of the connecting rod 25... The end is welded and fixed to the outer wall of the column 22. Several limiting holes 26 are equally spaced on the column 20. The second slider 24 is welded with a tube 27, and a rod 28 is inserted into the tube 27. One end of the rod 28 is inserted into the limiting hole 26. By pushing the rod 28 on the tube 27 and inserting one end of the rod 28 into the limiting hole 26, the position of the second slider 24 can be fixed, thereby limiting the height of the support frame 2. The column 22 and the second slider 24 can be connected by a connecting rod 25. A connecting plate 29 is screwed between the other ends of the two rods 28. A handle 30 is welded between the two tubes 27, and a pair of telescopic rods 31 are screwed onto the handle 30. The telescopic ends of the telescopic rods 31 are screwed and fixed to the connecting plate 29.Pushing the connecting plate 29 allows the insertion rod 28 to move out of the limiting hole 26. Pulling or pushing the handle 30 allows adjustment of the height of the support frame 2 using the second slider 24. Movable seats 32 are screwed to all four sides of the bottom of the base plate 19. One end of the bottom of each movable seat 32 has a hidden groove 33. A ground-inserting cone 34 is installed inside the hidden groove 33 via a rotating shaft. The other end of the bottom of the movable seat 32 has a roller 35, which allows the equipment to be moved. Rotating the ground-inserting cone 34 allows it to be perpendicular to the ground and inserted into the ground, thus fixing the position of the equipment.

[0026] In this embodiment, the initial position of the top of the top rod 6 is located at the bottom of the filter cylinder 4. During use, the equipment can be moved by the roller 35. By rotating the ground-inserting cone 34, making it perpendicular to the ground and inserting it into the ground, the position of the equipment can be fixed to prevent the equipment from moving during mining. By pushing the connecting plate 29 outward, the insertion rod 28 can be moved out of the limiting hole 26. Pulling or pushing the handle 30 can adjust the height of the support frame 2 using the second slider 24, so that the top of the support frame 2 is in contact with the top wall of the mining channel. Pulling the connecting plate 29 makes the insertion rod 28 inserted into the limiting hole 26, which can fix the position of the support frame 2, thereby forming a support effect. The damper 18 provides buffering for the support frame 2. Water seeping from the channel can flow into the filter cylinder 4 through the drainage hole 3. The filter cylinder 4 can filter the water. The water passes through the filter holes of the filter cylinder 4. The water seeps out and, guided by the arc plate 5, flows into the guide channel 15. The guide channel 15 then guides the water to the drain outlet 16 and discharges it. The guide plate 17 guides the discharged water outward. The coal slag and other impurities filtered out of the water will be temporarily stored in the filter cartridge 4. By pushing the base 13, the vertical rod 11 can be moved upward, and the support plate 9 squeezes the spring 10. The force is transmitted to the support 7 through the support plate 9 and the support rod 8, which can lift the arc plate 5 and move the top of the top rod 6 to the drain hole 3, thereby pushing out the filtered coal slag and other impurities, preventing the coal slag and other impurities from clogging the filter cartridge 4 and affecting the drainage effect. When the base 13 is released, the spring 10 will apply outward tension to move the support plate 9 downward and make the support plate 9 fit against the top of the limit frame 12. The rubber pad 14 can increase the friction between the hand and the base 13, thereby preventing slippage when pushing the base 13.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
