[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0036] Example 1

[0037] Please combine Figure 1-Figure 6 The present invention proposes an automatic grouting device for anchor support, including an actuator for grouting, one side of the actuator is connected to a feeding mechanism for slurry transfer, one side of the feeding mechanism is connected to a production mechanism for producing slurry, and the actuator ensures the entry of the anchor cable 35 and the transfer of slurry.

[0038] The actuator includes a limiting box 30 and a gasket 45. Among them: the two sides of the limiting box 30 are fixedly connected with a stabilizing cylinder 31, the middle of the limiting box 30 is rotatably connected with an outer ring 39, and the outer ring is provided with a power component and a limiting component. The limiting box 30 supports and stabilizes the main body, and the existing fixing parts can be inserted into the stabilizing cylinder 31 to limit the overall limiting box, thereby ensuring the stability of the entire device. The outer ring 39 can rotate in the limiting box 30, and the power component outputs power to ensure the movement of the anchor cable 35, and the limiting component realizes the limitation of the anchor cable 35.

[0039] The washer 45 is slidably connected to the outer ring 39, and one side of the washer 45 is fixedly connected to the inner sleeve 38 located inside the outer ring 39. The inner sleeve 38 is provided with an anchor cable 35 in contact with the power component. The outer side of the anchor cable 35 is connected to multiple follower tubes 34, and one end of the multiple follower tubes 34 is connected to a centralizing ring fixedly connected to the limiting box 30. The washer 45 is installed in the outer ring 39. The width of the washer 45 can be selected, and then different inner sleeves 38 can be snap-fitted and installed to adapt to the limitation of anchor cables 35 with different diameters.

[0040] The limiting assembly includes: a telescopic rod 43 and a limiting wheel. Among them: one side of the telescopic rod 43 is fixedly connected to a support frame fixedly connected to the outer ring 39, and the output end of the telescopic rod 43 is connected to a moving frame 44. The output end of the telescopic rod 43 extends, thereby driving the moving frame 44 to move.

[0041] The limiting wheel is fixedly connected to the moving frame 44 , one side of the limiting wheel contacts the anchor cable 35 , the movement of the moving frame 44 drives the movement of the limiting wheel, the teeth on the limiting wheel match the stripes on the anchor cable 35 , and the anchor cable 35 is limited.

[0042] One end of the follower tube 34 is fixedly connected to an expansion sleeve 50 which is sleeved with the anchor cable 35. A plurality of injection holes 52 are arranged on the expansion sleeve 50. One side of the expansion sleeve 50 is fixedly connected to a melting block 51 which is fixedly connected with the anchor cable 35. The expansion sleeve 50 is made of a flexible material. The injection holes 52 are used for fluid overflow. The melting block 51 is an alkali-soluble solid. During the grouting process, it is dissolved to achieve connection between the anchor cables 35, so that the expansion sleeve 50 can be further moved. Under the action of pressure, the expansion sleeve 50 can move along the anchor cable 35, driving the follower tube 34 to move along the connecting strip 53 to complete the work of withdrawing the tube.

[0043] The fixed end of the telescopic frame 48 is fixedly connected to the outer sleeve 39, and the output end of the telescopic frame 48 is rotatably connected to a transmission tooth 47 that is transmission-connected to the power assembly. One side of the transmission tooth 47 is in contact with the anchor cable 35, and the telescopic frame 48 can be telescoped. The outer sleeve 39 and the inner sleeve 38 are both provided with grooves for the transmission tooth 47 to pass through, ensuring that the transmission tooth 47 is in contact with the anchor cable 35. The transmission tooth 47 is transmission-connected to the transmission assembly 46 to achieve rotation, and under the action of friction, the anchor cable 35 is driven to move.

[0044] A connecting strip 53 which is connected to the anchor cable 35 is clamped on the follower tube 34, and a plurality of pressure sensors are connected to the expansion sleeve 50. The pressure sensors monitor the internal grouting pressure and provide grouting data to the grouting personnel.

[0045] The power assembly includes: a motor 2 49, which is fixedly connected to the outer ring 39, and the output end of the motor 2 49 is transmission-connected to the transmission 2 40, and the output end of the transmission 2 40 is transmission-connected to the transmission assembly 1 46. The motor 2 49 outputs power, and then after the speed change of the transmission 2 40, it drives the transmission assembly 1 46 to move. The transmission assembly 1 46 is composed of existing devices such as a worm gear, gears, and shafts to realize power transmission.

[0046] A symmetrically arranged stabilizing frame 32 is fixedly connected to the outer side of the limiting box 30, and a stabilizing rod 33 is rotatably connected to the stabilizing frame 32. The two stabilizing rods 33 are provided with mutually matching limiting grooves, and limiting holes are provided in the limiting grooves. One ends of the two stabilizing rods 33 cooperate with each other, and a pin is inserted into the limiting hole for limitation, thereby achieving limitation on one end of the anchor cable 35 to ensure subsequent work.

[0047] A plurality of rolling balls are embedded on the inner sleeve 38, and a limiting cone is provided in the stabilizing cylinder 31. The balls are in contact with the follower tube 34. The balls reduce friction during movement and limit the position of the follower tube 34. The limiting cone assists the limiting box to limit the connection to the rock formation.

[0048] The implementation principle of this embodiment is: after the drilling is completed, the inner sleeve 38 of the corresponding specification is selected and installed in the limiting box 30, and then holes are drilled around the hole, and the stabilizing cylinder 31 is snapped in, and the limiting box is limited by the limiting cone to complete the preliminary installation.

[0049] Then, the outer side of the anchor cable 35 is clamped with the connecting strip 53, and the texture of the anchor cable 35 cooperates with the connecting strip 53, and the follower tube 34 is installed at the same time, and the melting block 51 is installed on one side of the expansion sleeve 50 to make it fixedly connected with the follower tube 34. At this time, the transmission gear 47 is driven to rotate by the motor 2 49, the transmission 2 40 and the transmission component 1 46. Under the action of friction, the anchor cable 35 moves, driving the follower tube 34 to move and enter the inner side of the hole. When it reaches the bottom of the hole, the pressure sensor senses that the outside world is grouting into the inside through the follower tube 34. Under the dissolution of the alkaline solution, the melting block 51 dissolves, and at the same time, the high-pressure grouting makes the expansion sleeve 50 expand and block the hole, so that the internal pressure continues to rise. 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 to complete the grouting.

[0050] During the grouting process, the telescopic rod 43 works to move the movable frame 44, the limiting wheel contacts the anchor cable 35, limits the partial movement of the anchor cable 35, and rotates the stabilizing rod 33 to further limit the anchor cable 35, blocking its movement and ensuring the grouting process.

[0051] When the follower tube 34 is pushed forward or grouting is performed, the outer sleeve 39 can be rotated manually or passively to adapt to the entry of the anchor cable 35 and the removal of the follower tube 34 to ensure the work needs.
