Technical Field
[0001] This utility model relates to the field of mining support devices, and in particular to a high-strength mining support device. Background Technology
[0002] Mining support devices are key facilities used in mining operations to support underground spaces such as mine shafts and roadways. They prevent collapse accidents by resisting surrounding rock pressure and controlling rock deformation, thus ensuring the safety of personnel and equipment. According to their mode of operation, they can be divided into passive support that directly supports the surrounding rock by relying on its own structural strength (such as metal supports and shotcrete layers), active support that enhances the integrity of the surrounding rock by anchoring the rock mass (such as rock bolts and anchor cables), and dynamic support that is suitable for adjusting the support force in real time at the longwall face (such as hydraulic supports). In practice, combined support (such as the "anchor-mesh-shotcrete" combination) is often used. The selection of these devices needs to take into account factors such as geological conditions and mining technology. They are the core technical means to control ground pressure and reduce disaster risks in mine safety production.
[0003] However, current mining support devices have the following defects: First, they are not stable enough and are prone to tipping over, which affects the reliability of the support; second, they have limited capacity for crushing and handling, and the interception of crushed stones is not comprehensive. They also lack an effective stone removal mechanism, and the accumulation of crushed stones can easily lead to overload of the device, reduced protection effect, or even collapse.
[0004] In response to this technical problem, this application proposes a high-strength mining support device. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength mining support device. The device aims to enable the legs and connecting rods to form diagonal braces to support the fixed rods, thereby improving the stability of the support device. It also enables the device to intercept and discharge gravel, improving the device's protective effect and preventing it from being crushed by gravel.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A high-strength mining support device includes four base plates. A fixing rod is fixedly connected to the top side of each base plate. A hydraulic rod is installed inside each fixing rod. A crossbeam is fixedly connected to the top of the front and rear hydraulic rods. A protective plate is fixedly connected to the top side of each crossbeam. A protective net is fixedly connected to the top side of each protective plate. A support assembly is provided on one side of each fixing rod to improve its stability. A diagonal rod is rotatably connected to the top side of the front base plate. A stone-discharging plate is rotatably connected to one side of each crossbeam. A baffle is fixedly connected to the top side of the stone-discharging plate. The top of the diagonal rod is inserted into the bottom side of the stone-discharging plate. The stone-discharging plate and the diagonal rod are connected by a snap-fit assembly to fix them together.
[0008] Furthermore, the support assembly includes a groove formed on one side of the fixed rod, a threaded rod rotatably connected inside the groove, a slide block threadedly connected to the outer wall of the threaded rod, and the slide block slidably connected inside the groove.
[0009] Furthermore, a support leg is rotatably connected to one side of the base plate, and the slide and the support leg are connected by a connecting rod. One end of the connecting rod is rotatably connected to one side of the slide, and the other end of the connecting rod is rotatably connected to the inside of the support leg.
[0010] Furthermore, the top side of the fixed rod is rotatably connected to a handle via a damping shaft, and the top end of the threaded rod is fixedly connected inside the handle.
[0011] Furthermore, the buckle assembly includes two fixing plates fixedly connected to the top of the diagonal bar, a buckle plate rotatably connected to one side of the fixing plate, and two buckle rods fixedly connected to one side of the buckle plate.
[0012] Furthermore, a buckle ring is fixedly connected to the outer wall of the buckle rod, and the buckle rod and buckle ring are engaged inside the stone-laying plate. A lever plate is fixedly connected to the top side of the buckle plate.
[0013] Furthermore, two crossbars are fixedly connected between the front and rear fixed rods, and the protective plate and the crossbeam are connected by multiple struts.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the threaded rod is rotated by rotating the handle, which drives the slide to slide downward. This causes the slide to move the connecting rod downward, which in turn drives the outrigger to rotate and rotate it to the ground. This allows the outrigger and the connecting rod to form a diagonal brace to support the fixed rod, thereby improving the stability of the support device.
[0016] 2. In this utility model, the protective net will intercept larger stones, and the protective plate will intercept the remaining smaller stones that are not intercepted by the protective net. Then, the stone discharge plate will discharge the stones to the ground, thereby discharging the stones and preventing the stones from accumulating and collapsing the protective plate and protective net. This allows the device to intercept and discharge the stones, improving the device's protective effect and preventing it from being crushed by the stones. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figure 1 and Figure 2This utility model provides an embodiment of a high-strength mining support device, comprising four base plates 1. A fixing rod 3 is fixedly connected to the top side of each base plate 1. A hydraulic rod 9 is installed inside the fixing rod 3. Crossbeams 7 are fixedly connected to the top ends of the two front and rear hydraulic rods 9. Protective plates 5 are fixedly connected to the top sides of the two crossbeams 7. Protective nets 6 are fixedly connected to the top sides of the protective plates 5. The protective nets 6 intercept larger stones, while the protective plates 5 intercept smaller stones that are not intercepted by the protective nets 6. Both the protective plates 5 and the protective nets 6 are made of high-strength, lightweight metal materials, and both are designed with a higher center and lower sides, allowing the stones on top to roll along the slope to the sides for discharge. To prevent the accumulation of rubble from crushing the protective plate 5 and protective net 6, the height of the protective plate 5 and protective net 6 is adjusted using hydraulic rods 9 so that they can reach below the top of the mine shaft. A diagonal rod 10 is rotatably connected to the top side of the front bottom plate 1, and a stone-discharging plate 8 is rotatably connected to one side of the crossbeam 7. A baffle 13 is fixedly connected to the top side of the stone-discharging plate 8. The top of the diagonal rod 10 is inserted into the bottom side of the stone-discharging plate 8. By inserting the diagonal rod 10 into the bottom side of the stone-discharging plate 8, the stone-discharging plate 8 is supported, causing it to tilt at a certain angle to discharge the rubble. The baffle 13 seals the opening between the stone-discharging plate 8 and the crossbeam 7 to prevent rubble from falling through the opening and injuring workers. The stone-discharging plate 8 and the diagonal rod 10 are connected, as shown in the reference diagram. Figure 3 and Figure 4 A groove is provided on one side of the fixed rod 3, and a threaded rod 14 is rotatably connected inside the groove. A slide block 15 is threadedly connected to the outer wall of the threaded rod 14. The slide block 15 is slidably connected inside the groove. The threaded rod 14 drives the slide block 15 to slide. A support leg 2 is rotatably connected to one side of the base plate 1. The slide block 15 and the support leg 2 are connected by a connecting rod 11. One end of the connecting rod 11 is rotatably connected to one side of the slide block 15, and the other end of the connecting rod 11 is rotatably connected inside the support leg 2. The connecting rod 11 causes the support leg 2 to rotate when the slide block 15 slides, so that the support leg 2 and the connecting rod 11 form a diagonal brace to support the fixed rod 3, thereby improving the stability of the support device. A handle 16 is rotatably connected to the top side of the fixed rod 3 through a damping shaft. The top end of the threaded rod 14 is fixedly connected to the inside of the handle 16. The handle 16 causes the threaded rod 14 to rotate.
[0028] Reference Figures 5-7Two fixing plates 17 are fixedly connected to the top of the diagonal bar 10. A buckle plate 18 is rotatably connected to one side of the fixing plate 17. Two buckle rods 20 are fixedly connected to one side of the buckle plate 18. A buckle ring 21 is fixedly connected to the outer wall of the buckle rod 20. The buckle rod 20 and the buckle ring 21 are engaged inside the stone-laying plate 8. By rotating the buckle plate 18, the buckle rod 20 and the buckle ring 21 are engaged in the stone-laying plate 8, thereby fixing the stone-laying plate 8 and the diagonal bar 10 together. A lever plate 19 is fixedly connected to the top side of the buckle plate 18. By lever plate 19, the buckle plate 18 is rotated, thereby causing the buckle rod 20 and the buckle ring 21 to disengage from the stone-laying plate 8. Two crossbars 12 are fixedly connected between the front and rear fixing bars 3. The protective plate 5 and the crossbeam 7 are connected by multiple support rods 4. The crossbars 12 connect the front and rear fixing bars 3 together, and the multiple support rods 4 strengthen the support strength of the protective plate 5 and the protective net 6.
[0029] Working principle: First, the device is moved into the mine shaft. Then, the hydraulic rod 9 is activated to drive the protective net 6 and protective plate 5 to move towards the top of the mine shaft, so that the protective net 6 and protective plate 5 reach below the top of the mine shaft. Then, the stone-discharging plate 8 is rotated to rotate it next to the crossbeam 7 and make it horizontal. Next, the inclined rod 10 is rotated so that the end of the inclined rod 10 is aligned with the bottom side of the stone-discharging plate 8. Then, the stone-discharging plate 8 is rotated again so that the inclined rod 10 is inserted into the bottom side of the stone-discharging plate 8. Then, the buckling plate 18 is rotated so that the buckling rod 20 and the buckling ring 21 are engaged in the stone-discharging plate 8, thereby fixing the stone-discharging plate 8 and the inclined rod 10 together. This causes the stone-discharging plate 8 to tilt at a certain angle, and the baffle 13 seals the opening between the stone-discharging plate 8 and the crossbeam 7 to prevent crushed stones from falling from the opening and harming the workers. The impact causes damage. Then, the handle 16 is rotated to make the threaded rod 14 rotate, which drives the slide 15 to slide downward. This causes the slide 15 to move the connecting rod 11 downward, which in turn drives the support leg 2 to rotate through the connecting rod 11. This causes the support leg 2 to rotate to the ground, and the support leg 2 and the connecting rod 11 form a diagonal brace to support the fixed rod 3, thereby improving the stability of the support device. When gravel falls from the top of the mine, the protective net 6 will intercept the larger gravel, while the protective plate 5 will intercept the smaller gravel that is not intercepted by the protective net 6. These gravel will then roll along the slope towards the stone discharge plates 8 on both sides and eventually roll onto the stone discharge plates 8. Then, they will roll onto the ground through the stone discharge plates 8, thereby discharging the gravel and preventing the gravel from accumulating and crushing the protective plate 5 and the protective net 6.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
