Description

Technical Field

[0001] This utility model relates to the field of tunnel anchor grouting technology, specifically a high-efficiency tunnel anchor grouting machine. Background Technology

[0002] Tunnel anchor grouting is a key technology used in tunnel engineering to reinforce surrounding rock. By embedding anchors into the rock mass and injecting grout, the stability and bearing capacity of the surrounding rock are enhanced.

[0003] When transporting cement, existing tunnel anchor grouting machines first filter the cement through a grating plate to prevent large particles of impurities from entering the screw pump and thus avoiding blockage or damage. However, since the existing grating plate is fixed, it can only passively filter the cement by the falling cement, resulting in low filtration efficiency and making it unsuitable for filtering large quantities of cement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency tunnel anchor grouting machine, which can filter cement slurry through vibration filtration, prevent the filter cake from being too thick, reduce clogging, improve the filtration rate, and prevent cement slurry generated during vibration filtration from splashing and overflowing.

[0005] To achieve the above objectives, a high-efficiency tunnel anchor grouting machine is designed, comprising a machine body, on which a treatment chamber is fixedly installed. A grating plate is disposed within the cavity of the treatment chamber. A vertical groove is provided on the inner wall of the treatment chamber, and a slider conforming to the vertical groove is provided on the periphery of the grating plate, allowing the grating plate to reciprocate along the vertical groove. A vertically arranged fixed rod is provided on one side of the machine body, with a horizontal extension at the top of the fixed rod. A vertical hydraulic cylinder is fixedly installed on the bottom surface of the horizontal extension. The vertical hydraulic cylinder is fixedly connected to the grating plate via a vertically arranged first connecting rod, used to drive the grating plate to move up and down. The top of the treatment chamber has an opening, and two baffles are rotatably arranged on both sides of the opening. The baffles are rotatably connected to the treatment chamber via a rotating shaft, one end of which is provided with a rotating gear. The vertical hydraulic cylinder is fixedly connected to a vertical rack via a second connecting rod, and the vertical rack meshes with the rotating gear.

[0006] Preferably, the present invention further includes: the second connecting rod comprising: a first horizontal bar connected to the vertical hydraulic cylinder; a second horizontal bar arranged horizontally and connected to the first horizontal bar at a 90-degree angle; a first vertical bar arranged vertically and connected to the second horizontal bar, wherein the vertical rack is disposed at the lower part of the first vertical bar, and the first vertical bar meshes with a rotating gear through the vertical rack to realize the reversing transmission between the vertical hydraulic cylinder and the baffle plate.

[0007] Preferably, the present invention further includes: a relief groove with a groove structure is provided at the upper end of each of the two shielding plates, the relief groove being used to avoid the first connecting rod.

[0008] Preferably, the present invention further includes: a conveying chamber is provided at the lower end of the processing chamber, and a screw pump for conveying cement is installed in the conveying chamber.

[0009] Preferably, the present invention further includes: the processing chamber having an input port that communicates with the conveying chamber.

[0010] Preferably, the present invention further includes: a discharge pipe for discharging cement is fixedly installed at the opening of the conveying chamber.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] 1. In this invention, cement is first poured into the treatment chamber, and a vertical hydraulic cylinder drives the grating plate upward. The grating plate throws the cement to improve the filtration efficiency. At the same time, the vertical hydraulic cylinder drives the vertical rack upward, causing two baffles to rotate toward the opening of the treatment chamber, thereby blocking the opening and the cement thrown by the grating plate. This prevents cement from being wasted due to it moving out of the treatment chamber. This design forms a fully automated collaborative effect, requiring no personnel supervision. The baffles can open and close automatically to prevent cement from escaping, which is conducive to green and environmentally friendly construction.

[0013] 2. When the vertical hydraulic cylinder drives the grid plate to move downward, the grid plate filters the falling cement again, further improving the filtration efficiency of the cement. At the same time, the vertical hydraulic cylinder drives the vertical rack to move downward, so that the two baffles are in a vertical state, and the cement attached to the inner side of the two baffles flows downward into the treatment chamber, so as to facilitate the recycling of the cement.

[0018] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0019] This utility model provides a high-efficiency tunnel anchor grouting machine, comprising:

[0020] Reference Figures 1-3 A high-efficiency tunnel anchor grouting machine includes a body 1, a processing chamber 2 fixedly installed on the body 1, a grid plate 4 for filtering cement is slidably fitted on the processing chamber 2 through a vertical slide groove 3, two shielding plates 5 for blocking cement are rotatably arranged at the upper end of the processing chamber 2, and a drive mechanism for synchronously driving one grid plate 4 and two shielding plates 5 is provided on the body 1.

[0021] The processing chamber 2 is an upwardly open structure with an internal cavity. Several vertically arranged vertical grooves 3 are provided on the inner wall of the side wall of the processing chamber 2. The vertical grooves 3 have a recessed structure. A grid plate 4 is horizontally arranged within the cavity of the processing chamber 2. A slider, whose shape and size perfectly correspond to the vertical grooves 3, is provided on the outer periphery of the grid plate 4. The slider is embedded in the vertical groove 3, allowing the grid plate 4 to move up and down along the vertical groove 3, ensuring smooth sliding of the grid plate 4 in the vertical direction.

[0022] Preferably, the grating plate 3 has several through holes evenly distributed on it to trap large particles of impurities in the cement. A small gap is left between the grating plate 3 and the inner wall of the treatment chamber 2, which can prevent the grating plate 3 from rubbing and colliding with the treatment chamber 2 during movement and prevent large particles of impurities from flowing down through the gap between the grating plate 3 and the inner wall of the treatment chamber 2.

[0023] Preferably, the lower end of the processing chamber 2 is provided with a conveying chamber 6, and a screw pump 7 for conveying cement is installed in the conveying chamber 6; the processing chamber 2 is provided with an inlet 8 connected to the conveying chamber 6, and a discharge pipe 9 for discharging cement is fixedly installed at the opening of the conveying chamber 6. After the cement has been filtered, the cement enters the conveying chamber 6 through the inlet 8, and the screw pump 7 is started to pressurize and convey the cement, and the cement is conveyed to the tunnel anchor through the discharge pipe 9.

[0024] Preferably, the drive mechanism includes a vertical hydraulic cylinder 10 fixedly installed on the machine body 1. The vertical hydraulic cylinder 10 is fixedly connected to the grid plate 4 through the first connecting rod 11. The baffle plate 5 is rotatably connected to the processing chamber 2 through the rotating shaft 12. One end of the rotating shaft 12 is connected to the rotating gear 13 through a key.

[0025] Preferably, a vertical fixing rod is provided on one side of the machine body 1, and a horizontally extended part is provided at the top of the fixing rod. The horizontally extended part has a horizontal cantilever structure, and the vertical hydraulic cylinder 10 is vertically arranged at the bottom of the horizontally extended part.

[0026] Preferably, two vertically arranged fixing rods can be provided on each side of the body 1, and the horizontally arranged extension is connected to the top of the two fixing rods respectively.

[0027] A second connecting rod 14 is also connected to the vertical hydraulic cylinder 10. A vertical rack 15 is provided on one side of the second connecting rod 14. Therefore, when the vertical hydraulic cylinder 10 drives the grid plate 4 to move vertically, the two baffle plates 5 are synchronously driven to rotate through the meshing connection between the vertical rack 15 and the rotating gear 13. Both baffle plates 5 have clearance grooves 16 at their upper ends. When the two baffle plates 5 block the opening of the processing chamber 2, the clearance grooves 16 allow the first connecting rod 11 to pass.

[0028] Specifically, the second connecting rod 14 includes: a first horizontal rod connected to the vertical hydraulic cylinder 10; a second horizontal rod arranged horizontally and connected to the first horizontal rod at a 90-degree angle; and a first vertical rod arranged vertically and connected to the second horizontal rod. The vertical rack 15 is arranged on the lower side of the first vertical rod, and the first vertical rod meshes with the rotating gear 13 through the vertical rack 15 to realize the reversing transmission between the vertical hydraulic cylinder 10 and the baffle plate 5. Since the baffle plate 5 needs to open and close, sufficient space needs to be provided in the device for the baffle plate 5 to open and close. Therefore, the second connecting rod 14 needs to be provided with multiple bending structures to avoid the movement trajectory of the baffle plate 5. At the same time, it is also necessary to ensure sufficient transmission of the force on the vertical hydraulic cylinder 10 to the rotating parts. Therefore, a rigid connecting rod structure with fixed connection is required. In this process, the vertical hydraulic cylinder 10 reciprocates up and down, causing the first horizontal bar connected to it to also reciprocate up and down. The first horizontal bar is fixedly connected to the second horizontal bar and rotates at a 90-degree angle, thus changing the direction of the force. The first vertical bar, fixedly connected to the second horizontal bar, applies the reciprocating force of the vertical hydraulic cylinder 10 to the vertical rack 15, causing the rack 15 to reciprocate up and down. The rotating gear 13, meshing with the rack 15, is also driven to reciprocate and rotate. The baffle plate 5, fixedly connected to the rotating shaft 12, is also driven to reciprocate and rotate around the rotating shaft 12. Since the rotating shaft 12 is rotatably connected to the processing chamber 2 (preferably, an ear plate can be used to pass through the rotating shaft 12), and the baffle plate 5 covers the open structure of the processing chamber 2, the baffle plate 5 swings repeatedly at the open structure of the processing chamber 2, creating a continuous opening and closing motion. Preferably, two sets of shielding plates 5, rotating shafts 12 and rotating gears 13 can be symmetrically arranged on both sides of the open structure to form a split shielding and covering structure.

[0029] Preferably, the shielding plate 5 is provided with a relief groove 16 that conforms to the cross section of the first connecting rod 11. The relief groove 16 and the first connecting rod 11 form a relief, and when the shielding plate 5 is closed, the relief groove 16 and the first connecting rod 11 form a non-limiting and non-conflicting fit.

[0030] When the vertical hydraulic cylinder 10 moves downward, it presses the grille plate 4 downward. At this time, the vertical rack 15 moves downward, driving the rotating gear 13 to rotate. The baffle plate 5 is then lifted upward under the drive of the rotating gear 13 and the rotating shaft 12. At this time, the open structure of the processing chamber 2 is unobstructed, and the device is in the "open" state. When the vertical hydraulic cylinder 10 moves upward, it lifts the grille plate 4 upward. At this time, the vertical rack 15 moves upward, driving the rotating gear 13 to rotate. The baffle plate 5 is then lowered downward under the drive of the rotating gear 13 and the rotating shaft 12. At this time, the open structure of the processing chamber 2 is blocked by the baffle plate 5, and the device is in the "closed" state.

[0031] Preferably, the first connecting rod 11 and the second connecting rod 14 are connected to the vertical hydraulic cylinder 10 via a movable telescopic rod. This movable telescopic rod can be sleeved on the outside of the fixed end to prevent a limiting collision between the first connecting rod 11, the second connecting rod 14, and the fixed end of the vertical hydraulic cylinder 10. Alternatively, a movable telescopic rod can be installed inside the fixed end, with its end protruding beyond the end face of the fixed end to form a certain extension. The first connecting rod 11 and the second connecting rod 14 are connected to this extension. Since the extension of the movable telescopic rod always extends beyond the end face of the fixed end, a limiting collision between the first connecting rod 11, the second connecting rod 14, and the fixed end of the vertical hydraulic cylinder 10 can be avoided.

[0032] Preferably, the body 1 can be carried on a mobile vehicle with wheels, and the body 1 can also carry an energy storage device, a power generation device, and a hydraulic cylinder drive device.

[0033] The working principle of this utility model is as follows:

[0034] First, cement is poured into the treatment chamber 2 from the side of the machine body, and the vertical hydraulic cylinder 10 is activated. The vertical hydraulic cylinder 10 drives the grid plate 4 to move upward through the first connecting rod 11. The grid plate 4 throws the cement to improve the filtration efficiency of the cement. At the same time, the vertical hydraulic cylinder 10 drives the vertical rack 15 to move upward through the second connecting rod 14. Since the vertical rack 15 meshes with the rotating gear 13, the upper end of the rotating gear 13 at the front end of the machine body 1 rotates in the direction of the tangent to the rear end of the machine body 1. This causes the two baffle plates 5 to rotate towards the opening of the treatment chamber 2, thereby blocking the opening of the treatment chamber 2 and blocking the cement thrown by the grid plate 4, preventing the cement from moving out of the treatment chamber 2.

[0035] When the vertical hydraulic cylinder 10 moves the grating plate 4 downward, the grating plate 4 filters the falling cement again. At the same time, the vertical hydraulic cylinder 10 moves the vertical rack 15 downward so that the upper end of the rotating gear 13 at the front end of the machine body 1 rotates towards the front end of the machine body 1, so that the two baffles 5 are in a vertical state, allowing the cement attached to the inside of the two baffles 5 to flow downward into the treatment chamber 2.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and concept of this utility model, should be included within the protection scope of this utility model.
