Description

Technical Field

[0001] The present invention relates to the technical field of mine ecological restoration, and particularly relates to a reinforcement device for mine ecological restoration. Background Art

[0002] During the construction and mining of mines, it is inevitable to excavate a large amount of earth and stone. However, this excavation activity often leads to the destruction of the original vegetation, forming a large number of exposed slopes. These exposed slopes are not only prone to soil erosion but also may lead to ecological imbalance. Relying on the power of nature itself, the ecological restoration of these slopes is a slow and uncertain process. Therefore, artificial intervention becomes necessary.

[0003] Currently, in order to stabilize these exposed slopes and prevent geological disasters such as surface collapse and landslides, the method of burying cement piles is often used in engineering. Traditional cement pile construction technology usually involves directly pressing and pushing cement piles into the soil foundation. However, the construction difficulty increases when encountering a hard soil layer at the bottom inside the foundation, mainly because the hard soil layer has a large resistance to the pressing and pushing force, resulting in inconvenient traditional construction methods and low efficiency.

[0004] In order to optimize the convenience of burying cement piles, we propose a reinforcement device for mine ecological restoration. Summary of the Invention

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0042] Referring to Figures 1 - 12 One embodiment of the present invention discloses a reinforcement device for mine ecological restoration. Specifically, the reinforcement device includes a vehicle body 1 and a silo 2 installed on the vehicle body 1. The silo 2 is installed above the vehicle body 1, and the vehicle body 1 is moved to realize pile driving and reinforcement operations at different positions in the mine, thereby improving the convenience of the reinforcement operation;

[0043] Referring to Figure 3The bunker 2 is used to accommodate the foundation piles 3, and a pile feeding mechanism 4 for transferring the foundation piles 3 in the bunker 2 is arranged at the front end of the vehicle body 1;

[0044] A frame 5 is installed on the side of the vehicle body 1, a rotary pushing mechanism 7 is connected to the lower part of the frame 5 through a floating mechanism 6, and an impact mechanism 8 is further installed outside the rotary pushing mechanism 7. The impact mechanism 8 is used to perform pulsed pushing on the rotary pushing mechanism 7, so that the foundation pile 3 in the rotary pushing mechanism 7 impacts and drills holes in the foundation 9.

[0045] That is, in the present invention, through the design of the impact mechanism 8, pulsed impact is generated on the rotary pushing mechanism 7. When the foundation pile 3 encounters a hard soil layer during the process of being buried in the soil, the rotary pushing mechanism 7 cannot further drive the foundation pile 3 for pile driving and burying. At this time, the impact force of the impact mechanism 8 can be used to further impact the foundation pile 3 into the foundation 9. In addition, the foundation pile 3 in the present invention moves at multiple positions when entering the rotary pushing mechanism 7. In the present invention, the rotation and downward pushing methods are adopted to drive the foundation pile 3 into the interior of the foundation 9 to complete the reinforcement operation of the foundation 9.

[0046] Refer to Figure 4 In some embodiments, a temporary storage hopper 21 is installed at the bottom of the bunker 2 at its discharge port;

[0047] A pushing member 22 is fixedly installed at the back end of the bunker 2, a baffle plate 23 is fixedly installed at the telescopic end of the pushing member 22, and the baffle plate 23 is movably inserted between the temporary storage hopper 21 and the discharge port of the bunker 2. Preferably, the pushing member 22 in this embodiment can be set as a hydraulic cylinder, and the hydraulic cylinder drives the baffle plate 23 to perform telescopic movement to intermittently feed the foundation piles 3 in the bunker 2.

[0048] During specific operation, first, a plurality of foundation piles 3 are placed horizontally in the bunker 2. The movement of the vehicle body 1 drives the whole device to travel in the mine. When it moves to the position where pile driving and reinforcement are required, the vehicle body 1 is positioned at this time, and the foundation pile 3 slides downward by its own gravity. When a foundation pile 3 slides into the temporary storage hopper 21, the pushing member 22 starts to move to drive the baffle plate 23 to extend out. The baffle plate 23 stops at the discharge port of the bunker 2 to limit the foundation pile 3 in the bunker 2, thus avoiding the problem that the foundation piles 3 in the bunker 2 continuously slide and accumulate, affecting the movement of the subsequent pile feeding mechanism 4.

[0049] Refer to Figure 5 、 Figure 6, in an optional embodiment, the pile feeding mechanism 4 in the present invention includes a fixed seat 41 fixed on the vehicle body 1. An oscillating arm 42 is rotatably connected to the inner side of the fixed seat 41. Specifically, in this embodiment, the oscillating arm 42 is arranged in an arc structure. A lifting frame 43 for accommodating the foundation pile 3 is fixed to the top of the oscillating arm 42. The lifting frame 43 is movably connected in the temporary storage hopper 21. The lifting frame 43 includes a fixing plate and a plurality of U-shaped claws connected to the fixing plate. The plurality of U-shaped claws are used for accommodating the foundation pile 3. It should be noted that in the present invention, a plurality of avoidance openings are formed on the end surface of the temporary storage hopper 21, and the U-shaped claws are received in the avoidance openings in the initial state;

[0050] Refer to Figure 6 , wherein a first motor 44 is fixedly installed on the end surface of the fixed seat 41, a first gear 45 is fixedly installed on the shaft end of the first motor 44, and a rack portion 46 meshing with the first gear 45 is arranged on the inner side surface of the oscillating arm 42.

[0051] That is, when the foundation pile 3 slides into the interior of the temporary storage hopper 21, the foundation pile 3 will slide inside the lifting frame 43. In order to feed the foundation pile 3 into the clamping and pushing assembly 74 for pile driving, in the present invention, the first motor 44 can be driven to drive the first gear 45 to rotate. Since the first gear 45 and the rack portion 46 are in meshing transmission, the entire oscillating arm 42 will be driven to rotate. At this time, the oscillating arm 42 drives the lifting frame 43 to rotate and lift, so as to lift the foundation pile 3 in the lifting frame 43. When lifted to a predetermined angle, the foundation pile 3 starts to slide downward until it falls into the interior of the clamping and pushing assembly 74 to complete the transfer and feeding of the foundation pile 3.

[0052] Refer to Figure 7 , further, the floating mechanism 6 in the present invention includes a plurality of guide rods 61 inserted into the frame 5. The plurality of guide rods 61 are circumferentially distributed. A first spring 62 is connected between the guide rods 61 and the frame 5. It should be noted that in the present invention, in order to enable the foundation pile 3 to enter the rotary pushing mechanism 7 from the inner side of the frame 5, the frame 5 can be arranged in a circular structure. When specifically conveying the foundation pile 3, the foundation pile 3 can be conveyed downward along the inner hole of the frame 5;

[0053] A fixing bracket 63 is commonly connected between the bottoms of the plurality of guide rods 61. A first gear ring 64 is arranged on the outer periphery of the fixing bracket 63. That is, in the present invention, by means of the elastic telescopic force of the first spring 62, the floating function of the fixing bracket 63 is realized. Of course, the above-mentioned rotary pushing mechanism 7 is connected to the fixing bracket 63, so as to realize the subsequent impact pile driving of the foundation pile 3.

[0054] Refer to Figure 7 , Figure 9, in some embodiments, the rotation and pushing mechanism 7 in the present invention includes a rotating bracket 71 rotatably connected to the fixed bracket 63. In this embodiment, a convex ring can be provided on the outer side of the fixed bracket 63, and an annular groove is provided on the inner side of the rotating bracket 71. Through the rotational cooperation of the annular groove and the convex ring, the connection and rotation between the rotating bracket 71 and the fixed bracket 63 are realized. At least one second motor 72 is fixed to the upper end of the rotating bracket 71, and a second gear 73 meshing with the first gear ring 64 is fixedly installed at the shaft end of the second motor 72. Optionally, in order to ensure the stability of the driving rotation, three second motors 72 are installed in this embodiment, and the three second motors 72 are circumferentially distributed. Of course, the second motor 72 can be set as a servo motor to ensure the consistency of movement;

[0055] A plurality of clamping and pushing assemblies 74 are further installed at the bottom of the rotating bracket 71.

[0056] Refer to Figure 8 , preferably, in this embodiment, the clamping and pushing assembly 74 includes an outer frame 741 fixed to the bottom of the rotating bracket 71. In this embodiment, the clamping and pushing assembly 74 can also be set to three. An inner frame 743 is movably inserted into the end face of the outer frame 741 through a rod and a second spring 742. Specifically, in this embodiment, two rods are configured and are respectively fixed to the upper and lower sides inside the outer frame 741. The inner frame 743 is movably inserted into the rod, and the second spring 742 is located between the outer frame 741 and the inner frame 743;

[0057] A plurality of clamping wheels 744 are rotatably connected to the end face of the inner frame 743. Anti-slip teeth are provided on the outer circumference of the clamping wheels 744 to ensure the clamping stability of the foundation pile 3. The clamping wheels 744 on a plurality of clamping and pushing assemblies 74 surround the outside of the foundation pile 3.

[0058] Refer to Figure 7 , Figure 8 , in an alternative embodiment, a third motor 745 is further fixedly installed on the end face of the inner frame 743 in the present invention. A worm 746 is fixedly installed at the shaft end of the third motor 745. A plurality of clamping wheels 744 on each inner frame 743 are linearly distributed, and a worm gear 747 is fixedly installed on the rotating shaft of the clamping wheel 744. The worm 746 meshes with a plurality of linearly distributed worm gears 747 for transmission. It should be noted that the above clamping wheel 744 and the rotating shaft are fixedly connected. In this way, when the worm 746 drives the worm gear 747, the clamping wheel 744 can be driven to rotate.

[0059] That is to say, in the present invention, through the design of the second spring 742 abutting against the inner frame 743, a plurality of clamping wheels 744 on the inner frame 743 can be firmly clamped on the outer side of the foundation pile 3, so as to ensure the pushing stability of the foundation pile 3.

[0060] During the specific piling process, when the foundation pile 3 enters between multiple inner frames 743 along the frame 5, a plurality of clamping wheels 744 on the three inner frames 743 clamp the foundation pile 3. Since a second spring 742 is provided between the inner frame 743 and the outer frame 741, the clamping wheels 744 can be firmly clamped on the outer side of the foundation pile 3.

[0061] During piling, the third motor 745 drives the worm 746 to rotate. Since the worm 746 and the worm wheels 747 on a plurality of clamping wheels 744 rotate synchronously, the clamping wheels 744 can be driven to rotate by the rotation of the worm wheels 747, so as to achieve the purpose of pushing the foundation pile 3 downward for piling.

[0062] At the same time, during this process, the second motor 72 drives the second gear 73 to rotate. Since the second gear 73 meshes with the first toothed ring 64 on the fixed bracket 63, the entire rotating bracket 71 will rotate circumferentially, and the circumferential rotation of the foundation pile 3 is driven by means of the clamping force of the internal clamping wheels 744. That is, in the present invention, the operation mode of rotating and linearly pushing the foundation pile 3 is adopted during piling, so that the operation efficiency of driving the foundation pile 3 into the foundation 9 is greatly improved.

[0063] Refer to Figure 10 、 Figure 11 、 Figure 12 Furthermore, in the present invention, the impact mechanism 8 includes an impact frame 81 fixed on the rotating bracket 71. A piston 83 is movably connected to the inner side of the impact frame 81 through a compression spring 82. A chute 84 is provided on the outer side of the impact frame 81. The inner side of the impact frame 81 is divided into an exhaust chamber 811 and a sealing chamber 812 along the bottom tangent of the chute 84. An explosion assembly 85 is provided on the inner side of the impact frame 81, and a lifting assembly 86 for lifting the piston 83 is provided on the outer side of the impact frame 81.

[0064] Refer to Figure 11, in an optional embodiment, the explosion assembly 85 in the present invention includes a fuel tank 851 and an oil pump 852 installed outside the impact frame 81. The oil pump 852 is connected to the fuel tank 851 through a pipeline. Of course, in order to supplement the fuel in the fuel tank 851, a fuel tank cap is provided on the fuel tank 851 to facilitate opening for fuel supplementation. The output end of the oil pump 852 communicates with the sealing cavity 812. Of course, the output end of the oil pump 852 can also be connected to an atomizing nozzle to make the sprayed fuel in the form of oil mist. An igniter 853 is also installed in the sealing cavity 812. In this embodiment, by moving the piston 83 into the sealing cavity 812 to generate high pressure, and at the same time the oil pump 852 pumps out the fuel in the fuel tank 851, at this time, high pressure and oil mist are generated inside the sealing cavity 812. When the igniter 853 ignites, an ignition explosion occurs inside the sealing cavity 812. Those skilled in the art know that during the ignition explosion process, the pressure inside the sealing cavity 812 rapidly increases, and at the same time, a downward reaction force is generated on the entire impact frame 81. In this way, with the reaction force, the impact frame 81 drives the entire rotating bracket 71 to move downward. Since the clamping wheels 744 inside the rotating bracket 71 clamp and fix the foundation pile 3, and the clamping wheels 744 are driven by a worm gear 747 and a worm 746, therefore, relying on the self-locking ability of the worm gear 747 and the worm 746, the clamping wheels 744 will not reverse. Therefore, when the entire rotating bracket 71 moves downward, the multiple clamping wheels 744 drive the foundation pile 3 to impact downward in pulses, punching holes in the hard soil layer. After that, the rotating bracket 71 is reset by the floating mechanism 6 and pulls the foundation pile 3 upward to reset. Since there are already punched hole positions in the soil layer at this time, the foundation pile 3 can be further conveyed downward by the rotation of the multiple clamping wheels 744;

[0065] Of course, if the hard soil layer is relatively thick, the actions of impacting the foundation pile 3 in pulses, resetting, and conveying downward can be repeated, so as to gradually bury the foundation pile 3 into the foundation 9 to complete the reinforcement operation of the foundation 9.

[0066] Referring to Figure 12 , in addition, the lifting assembly 86 in the present invention includes two belt pulleys 861 rotatably connected to the outside of the impact frame 81, and a synchronous belt 862 is connected between the two belt pulleys 861;

[0067] A shift lever 863 is fixedly installed on the side of the synchronous belt 862, and a sliding seat 831 is fixedly installed on the side of the piston 83. The sliding seat 831 is slidably connected in the chute 84 and abuts against the shift lever 863;

[0068] A third gear 864 is fixedly installed on the shaft end of the upper belt pulley 861, and a second toothed ring 65 meshing with the third gear 864 is provided at the bottom of the fixed bracket 63.

[0069] That is, when the foundation pile 3 is being driven into the foundation 9 and encounters a hard soil layer, the above-mentioned pushing operation method cannot further push the foundation pile 3 into the foundation 9. Therefore, in the present invention, the operation method of the impact mechanism 8 is used to further assist the entire pile driving operation of the foundation pile 3.

[0070] Furthermore, in the present invention, the movement of the piston 83 and the rotational movement of the rotating bracket 71 are linked to ensure that during the pile driving operation of the foundation pile 3 in rotation and linearly, the impact pile driving effect of the foundation pile 3 is further synchronously achieved, thus greatly improving the embedding efficiency of the foundation pile 3.

[0071] Specifically, during operation, the rotating and pushing mechanism 7 drives the foundation pile 3 to rotate and is linearly conveyed downward into the soil layer of the foundation 9. During this process, since the rotating bracket 71 rotates reciprocally, the entire impact frame 81 will also rotate reciprocally following the rotating bracket 71. Since the third gear 864 is fixed to the shaft end of the pulley 861 on the upper side of the impact frame 81, when the impact frame 81 moves circumferentially, the third gear 864 will continuously rotate by virtue of the meshing force with the second toothed ring 65;

[0072] At this time, the upper pulley 861 drives the lower pulley 861 to rotate through the synchronous belt 862. Since the outer side of the synchronous belt 862 is fixedly installed with a lever 863, every time the synchronous belt 862 rotates one circle, the piston 83 will be lifted upward by the sliding seat 831. When the lever 863 moves to the uppermost side, it will separate from the sliding seat 831. Thereafter, under the action of the compression spring 82, the piston 83 quickly moves downward until it moves into the sealing cavity 812 and causes a high pressure inside the sealing cavity 812. At the same time, the oil pump 852 supplies oil and the igniter 853 ignites, so that an explosion occurs inside the sealing cavity 812. By means of the reaction force of the explosion, the entire rotating bracket 71 moves downward, causing the foundation pile 3 to impact downward to punch holes in the hard soil layer. Thereafter, when the foundation pile 3 returns upward, the clamping wheel 744 rotates to convey the foundation pile 3 downward continuously. In this way, it reciprocates continuously to achieve multiple actions of rotating, conveying, and impacting the foundation pile 3 during pile driving, greatly improving the embedding efficiency of the foundation pile 3 and the efficiency of the operation.

[0073] In summary, through the design of the rotary pushing mechanism 7 provided in the present invention, during the process of driving the foundation pile 3 into the foundation 9, the foundation pile 3 is driven to rotate and move downward in a straight line. In addition, considering that during the driving process, the soil layer at the lower part of the foundation 9 is hard and the straight-line conveying operation cannot further drive the foundation pile 3 into the foundation, therefore, in the present invention, through the design of the impact mechanism 8, it is used to generate pulse impacts on the rotary pushing mechanism 7, and with the impact force of the impact mechanism 8, the foundation pile 3 is further impacted into the foundation 9 to punch holes in the hard soil layer to facilitate the driving of the foundation pile 3, so as to achieve multiple actions of rotating, conveying, and impacting the foundation pile 3 during pile driving, greatly improving the driving efficiency of the foundation pile 3 and the efficiency of the operation.

[0074] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
