[0035] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0036] Example 1:
[0037] Referring to Figures 1-6, this solution proposes an automatic grouting device for anchoring support, which includes an actuator for grouting, a feeding mechanism for grout transfer connected to one side of the actuator, and a grout production mechanism connected to one side of the feeding mechanism. The actuator ensures the entry of the anchor cable 35 and the transfer of grout.
[0038] The actuator includes a limiting box 30 and a washer 45. Specifically: stabilizing cylinders 31 are fixedly connected to both sides of the limiting box 30, and an outer ring 39 is rotatably connected to the center of the limiting box 30. The outer ring is equipped with a power component and a limiting component. The limiting box 30 provides support and stability for the main body. Existing fasteners can be inserted into the stabilizing cylinders 31 to limit the overall limiting box, thereby ensuring the stability of the entire device. The outer ring 39 can rotate within the limiting box 30. The power component provides power output to ensure the movement of the anchor cable 35, and the limiting component limits the anchor cable 35.
[0039] Washer 45 is slidably sleeved with outer ring 39. One side of washer 45 is fixedly connected to inner sleeve 38 located inside outer ring 39. An anchor cable 35 that contacts the power component is provided inside inner sleeve 38. Multiple follower tubes 34 are connected to the outside of anchor cable 35. One end of multiple follower tubes 34 is connected to a central ring that is fixedly connected to limiting box 30. Washer 45 is installed inside outer ring 39. The width of washer 45 can be selected, thereby snapping on different inner sleeves 38 to accommodate anchor cables 35 of different diameters.
[0040] The limiting components include: a telescopic rod 43 and limiting wheels. Specifically: a support frame fixedly connected to an outer sleeve 39 is fixedly connected to one side of the telescopic rod 43; a movable frame 44 is connected to the output end of the telescopic rod 43; the output end of the telescopic rod 43 extends, thereby driving the movable frame 44 to move.
[0041] The limiting wheel is fixedly connected to the movable frame 44. One side of the limiting wheel is in contact with the anchor cable 35. The movement of the movable frame 44 drives the movement of the limiting wheel. The teeth on the limiting wheel match the stripes on the anchor cable 35, thereby limiting the anchor cable 35.
[0042] One end of the follower tube 34 is fixedly connected to an expansion sleeve 50 that is sleeved with the anchor cable 35. The expansion sleeve 50 is provided with multiple injection holes 52. A melting block 51 that is fixedly connected to the anchor cable 35 is fixedly connected to one side of the expansion sleeve 50. The expansion sleeve 50 is made of flexible material. The injection holes 52 allow fluid to overflow. The melting block 51 is an alkali-soluble solid that dissolves during the grouting process, enabling the anchor cables 35 to connect and allowing the expansion sleeve 50 to move further. Under pressure, the expansion sleeve 50 can move along the anchor cable 35, driving the follower tube 34 to move along the connecting strip 53, thus completing the tube retraction work.
[0043] The fixed end of the telescopic frame 48 is fixedly connected to the outer sleeve 39. The output end of the telescopic frame 48 is rotatably connected to the transmission gear 47, which is connected to the power component. One side of the transmission gear 47 is in contact with the anchor cable 35. The telescopic frame 48 can extend and retract. The outer sleeve 39 and the inner sleeve 38 are both provided with grooves for the transmission gear 47 to pass through, ensuring that the transmission gear 47 is in contact with the anchor cable 35. The transmission gear 47 is connected to the transmission component 46 to achieve rotation. Under the action of friction, the anchor cable 35 is moved.
[0044] The follower tube 34 is fitted with a connecting strip 53 that is fitted with the anchor cable 35. The expansion sleeve 50 is connected with multiple pressure sensors. The pressure sensors monitor the internal grouting pressure and provide grouting data to the grouting personnel.
[0045] The power assembly includes: a second motor 49, which is fixedly connected to an outer ring 39. The output end of the second motor 49 is connected to a second gearbox 40, and the output end of the second gearbox 40 is connected to a first transmission assembly 46. The second motor 49 outputs power, which is then driven by the second gearbox 40 to drive the first transmission assembly 46. The first transmission assembly 46 is composed of existing devices such as worm gears, gears, and shafts to realize the transmission of power.
[0046] A symmetrically arranged stabilizing frame 32 is fixedly connected to the outside of the limiting box 30. A stabilizing rod 33 is rotatably connected to the stabilizing frame 32. The two stabilizing rods 33 are provided with mutually cooperating limiting grooves. A limiting hole is provided in the limiting groove. One end of the two stabilizing rods 33 cooperates with each other and a pin is inserted into the limiting hole to limit the anchor cable 35, thereby limiting one end of the anchor cable 35 and ensuring subsequent work.
[0047] Multiple balls are rolled and embedded on the inner sleeve 38. A limiting cone is provided inside the stabilizing cylinder 31. The balls are in contact with the follower tube 34. The balls ensure that friction is reduced during movement and limit the position of the follower tube 34. The limiting cone assists the limiting box in limiting the connection to the rock layer.
[0048] The implementation principle of this embodiment is as follows: After drilling, the inner sleeve 38 of the corresponding specification is selected and installed into the limiting box 30. Then, holes are drilled around the hole, and the stabilizing cylinder 31 is snapped in. After the limiting cone limits the limiting box, the initial installation is completed.
[0049] Then, the outer side of the anchor cable 35 is snapped with the connecting strip 53, utilizing the texture of the anchor cable 35 to cooperate with the connecting strip 53. At the same time, the follower tube 34 is installed, and the melting block 51 is installed on one side of the expansion sleeve 50, making it fixedly connected to the follower tube 34. At this time, driven by the second motor 49, the second gearbox 40 and the first transmission component 46, the transmission gear 47 is driven to rotate. Under the action of friction, the anchor cable 35 moves, driving the follower tube 34 to move into the inside of the hole. When it reaches the bottom of the hole, the pressure sensor detects that grout is injected into the inside through the follower tube 34. Under the dissolution of the alkaline solution, the melting block 51 dissolves. At the same time, the high-pressure grouting causes the expansion sleeve 50 to expand, blocking the hole and causing the internal pressure to rise continuously. Under the action of pressure, the expansion sleeve 50 moves along the connecting strip 53 and the anchor cable 35, and finally moves out of the hole, completing the grouting.
[0050] During the grouting process, the telescopic rod 43 works to move the moving frame 44, and the limiting wheel contacts the anchor cable 35, limiting the partial movement of the anchor cable 35. The rotating stabilizing rod 33 further limits the anchor cable 35, preventing its movement and ensuring the grouting process.
[0051] When advancing the follower pipe 34 or grouting, the outer ring 39 can be rotated manually or passively to accommodate the entry of the anchor cable 35 and the exit of the follower pipe 34, ensuring the needs of the operation are met.
[0052] Example 2:
[0053] Referring to Figures 1-9, in this embodiment, the production mechanism includes a mounting plate 01, a moving ring 24, and a transmission assembly 26. Specifically: a mixing cylinder 03 is fixedly connected to the middle of the mounting plate 01; a motor 11 is connected to the top of the mixing cylinder 03; a gearbox 12 is driven to the output end of the motor 11; and a sliding sleeve, rotatably connected to the mixing cylinder 03, is driven to the output end of the gearbox 12. The sliding sleeve is connected to a power shaft 19 via a spline drive. The mixing cylinder 03 provides temporary storage for raw materials and a mixing / stirring space; the gearbox 12 performs speed changes; the motor 11 outputs power; and the power shaft 19 rotates in tandem with the transmission of the gearbox 12, thus achieving mixing / stirring and power transmission.
[0054] The moving ring 24 is slidably sleeved with the mixing cylinder 03. Multiple moving shafts 20 are rotatably connected to the moving ring 24. A mixing ball 22 is fixedly connected to the top of the moving shaft 20. Multiple mixing rods 21 are fixedly connected to the mixing ball 22. A narrow gear 18 is fixedly sleeved at the bottom of the moving shaft 20. The narrow gear 18 meshes with a wide gear fixedly sleeved with the power shaft 19. The moving ring 24 divides the space inside the mixing cylinder 03. At the same time, the rotation of the transmission moving shaft 20 synchronously drives the mixing ball 22 and the mixing rods 21 to rotate, thereby achieving further mixing and stirring and ensuring the internal processing work.
[0055] The transmission assembly 26 is fixedly connected to the bottom of the mixing cylinder 03. The output end of the transmission assembly 26 is connected to multiple support shafts 17. The outer side of the support shafts 17 is fixedly connected to a hemispherical block 27 that contacts the moving ring 24. The transmission assembly 26 is a combination of existing gears, gear rings, bevel gears, transmission shafts and other existing mechanisms to meet more specific needs, realize transmission in multiple directions, drive the support shafts 17 to rotate, further drive the hemispherical block 27 to rotate, so that the moving ring 24 moves up and down, realizing the need for vibration and auxiliary mixing.
[0056] The feeding mechanism includes: discharge pipe 25, screw conveyor 08, and air pipe 23. One end of discharge pipe 25 is connected to mixing drum 03, and the other end is connected to guide pipe 16. Discharge pipe 25 guides the discharge, allowing the raw materials in mixing drum 03 to flow freely and meet operational needs. Depending on specific usage requirements, a cement pump can be installed between guide pipe 16 and discharge pipe 25 to assist in concrete extraction and ensure the movement of the extracted concrete.
[0057] The screw conveyor 08 is fixedly connected to the mounting plate 01. The input end of the screw conveyor 08 is connected to one end of the guide pipe 16. The output end of the screw conveyor 08 is connected to the concentrating sleeve 06. One end of the concentrating sleeve 06 is connected to the finished product pipe 14 connected to the concentrating ring. The screw conveyor 08 performs extrusion transport, so that the raw material enters the concentrating sleeve 06, and then enters the concentrating ring through the finished product pipe 14, replenishing the raw material in the follower pipe 34.
[0058] One end of the air pipe 23 is connected to the central sleeve 06, and the other end of the air pipe 23 is connected to the air pump 07 located on the mounting plate 01. The air pipe 23 guides air, and the air pump 07 can be turned off or turned on to supply air according to specific usage requirements. According to the specific concrete curing requirements, when air supply is required, some gas can be added to the concrete to form foam concrete. While ensuring the overall strength meets the requirements, the weight of the concrete is reduced and the setting speed is accelerated.
[0059] A counterweight is fixedly connected to the mounting plate 01, and multiple mounting strips are fixedly connected to the bottom of the mounting plate 01. A symmetrically arranged raw material box 02 is fixedly connected to the mounting plate 01. A conveying pump is installed inside the raw material box 02, and the output end of the conveying pump is connected to a conveying pipe connected to the feed pipe 13. The top of the mixing cylinder 03 is connected to the feed pipe 13, and a camera and controller are fixedly connected to the mixing cylinder 03. The counterweight provides counterweight, and the raw materials are stored in the raw material box 02 and transported and added through the conveying pump and conveying pipe to ensure continuous operation.
[0060] This embodiment, based on Embodiment 1, further improves upon the following: During operation, raw materials are added to the mixing drum 03 via the raw material box 02. The motor 11 in the mixing drum 03 operates, and through the gearbox 12, it drives the power shaft 19 to rotate. Through the transmission of the guide pipe 16, it drives the support shaft 17 to rotate. Simultaneously, the narrow gear 18 drives the moving shaft 20 to rotate. The support shaft 17 drives the hemispherical block 27 to rotate, thereby causing the moving ring 24 to move up and down, generating vibration and expelling excess gas from the concrete. This ensures mixing while facilitating subsequent operations. The moving shaft 20 drives the mixing ball 22 and the air pipe 23 to rotate, performing different mixing methods to improve overall mixing efficiency. After mixing, the concrete is introduced into the screw conveyor 08 through the discharge pipe 25 and the guide pipe 16 for pressurized transportation. Finally, it enters the centralized ring through the centralized sleeve 06 and the finished product pipe 14 for injection, completing the automatic grouting process.
[0061] Example 3:
[0062] An automatic grouting method for anchoring support includes the following steps:
[0063] S1: Survey the drilling location and conduct preliminary drilling. The diameter of the drill hole should be 1 to 10 cm larger than the radius of the anchor cable.
[0064] S2: Clean the area around the hole, install the actuator, and connect the actuator to the anchor cable;
[0065] S3: Insert the anchor cable into the hole, then grout it, while the production unit mixes the concrete.
[0066] S4: When the expansion sleeve moves to the opening, close the feeding mechanism, remove the follower tube, and restrict the anchor cable;
[0067] S5: Perform ultrasonic testing on the grouting site to verify the grouting quality.
[0068] The implementation principle of this application embodiment is as follows: After exploration drilling, the hole diameter is ensured to allow the anchor cable 35 and the follower tube 34 to pass through. When the bottom is reached, the sensor obtains data and outputs it. The feeding mechanism feeds the material, and concrete is added into the hole. The pressure rises, and at the same time, the melting block 51 is dissolved. The expansion sleeve 50 expands under the pressure of the concrete, and the internal concrete pressure causes the expansion sleeve 50 to move, which in turn drives the follower tube 34 to move outward to realize grouting and complete the work. The limiting box 30 and the follower tube 34 are then recovered to await subsequent work.
[0069] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention.
