[0032] Reference Figures 1 to 6 , the present invention provides a technical solution: an anchor hole grouting control device, comprising: a connecting base 1, a grouting pipe 2, an adjusting mechanism 4, and a control mechanism 5;

[0033] The grouting pipe 2 is fixed on the connecting base 1 and communicated with the connecting base 1. The grouting pipe 2 is used to grout the anchor hole. One end of the shell 3 is also fixed to the connecting base 1. The shell 3 is coaxially sleeved on the grouting pipe 2.

[0034] The regulating mechanism 4 is arranged at the other end of the shell 3 and is used to control and adjust the grouting state; the control mechanism 5 is installed inside the shell 3 and is connected to the grouting pipe 2, and is used to collect lost mortar during the grouting process and cut off the grouting pipe 2 after the grouting is completed.

[0035] The base 1 is connected to the grouting equipment, the grouting pipe 2 is inserted into the anchor hole, and the shell 3 is pushed downward, so that the adjustment mechanism 4 seals the anchor hole, and part of the mortar flowing out of the anchor hole enters the shell 3 to prevent the mortar from being lost during the grouting process. After the sealing is completed, the grouting equipment is started, and the mortar flows into the anchor hole through the grouting pipe 2. When the anchor hole is initially filled with mortar, during the grouting process, part of the mortar will enter the shell 3 through the adjustment mechanism 4 and squeeze the control mechanism 5. Under the pressure provided by the control mechanism 5, the mortar in the anchor hole is squeezed to expel the bubbles therein, thereby improving the quality of grouting and ensuring the effect of grouting. When the anchor hole is completely filled with mortar, that is, after all the mortar gas in the anchor hole has been exhausted, grouting continues, and the mortar will all flow into the shell 3 and act on the control mechanism 5, so that the control mechanism 5 cuts off the grouting pipe 2, completing the grouting operation of the anchor hole.

[0036] After the grouting is completed, the shell 3 is lifted to release the seal of the anchor hole opening by the adjustment mechanism 4. At this time, the adjustment mechanism 4 seals the shell 3, thereby preventing the mortar inside it from flowing out and dripping, avoiding waste of mortar, and achieving the purpose of saving; the next time the adjustment mechanism 4 seals the anchor hole opening, the adjustment mechanism 4 releases the seal of the shell 3, so that the mortar inside the shell 3 is squeezed out under the action of the control mechanism 5 and flows into the new anchor hole, and at the same time, the control mechanism 5 releases the cut-off of the grouting pipe 2, so that the mortar in the grouting equipment is re-injected into the anchor hole through the grouting pipe 2.

[0037] As a preferred embodiment, the adjustment mechanism 4 includes: a slide 41, one end of the slide 41 is fixed to the housing 3, and the other end is provided with a slide groove, through which one end of an adjustment ring 42 is slidably arranged, and the other end of the adjustment ring 42 is fixed with an elastic fixing ring sleeve, which is used to prevent mortar loss;

[0038] A valve channel 45 is provided at the top of the housing 3 , and a regulating valve 44 is slidably arranged in the valve channel 45 ;

[0039] The pressing platform 43 is fixedly arranged on the adjusting collar 42 corresponding to the position of the regulating valve 44 .

[0040] As a preferred embodiment, an annular spring is provided between the sliding groove and the adjusting collar 42 .

[0041] It should be noted that during the process of sealing the anchor port, the adjusting ring 42 slides under pressure and squeezes the annular spring. Under the reaction force of the annular spring, the elastic fixing ring sleeve fits tightly with the anchor port to achieve a sealing effect, thereby preventing mortar from dripping during the grouting process.

[0042] At the same time, during the descent of the adjusting collar 42, the adjusting valve 44 is slid by the pressing platform 43, thereby releasing the sealing effect on the valve channel 45, so that the mortar dripping during the grouting process will enter the shell 3 for collection, and when the anchor hole is initially filled with mortar, the reaction force of the control mechanism 5 can act on the mortar in the anchor hole, thereby discharging the gas in the mortar in the anchor hole and improving the grouting effect and quality of the mortar.

[0043] When the opening of the next anchor hole is sealed, the opening of the valve channel 45 will allow the mortar in the shell 3 to flow out under the action of the control mechanism 5 and enter the anchor hole, avoiding waste of mortar and improving the utilization rate of the mortar.

[0044] As a preferred embodiment, the regulating valve 44 includes: a blocking platform 441, an upper pressing platform 442, and a lower pressing platform 443;

[0045] The blocking platform 441 is slidably arranged in the valve channel 45; the upper pressing platform 442 and the lower pressing platform 443 are symmetrically fixed on both sides of the blocking platform 441, and limit platforms are fixedly arranged on both sides of the upper pressing platform 442 and the lower pressing platform 443.

[0046] As a preferred embodiment, the adjustment mechanism 4 also includes: a boss 46, which is fixedly arranged in the shell 3 corresponding to the pressing platform 443, and one end of the adjustment spring 47 is fixedly arranged on the boss 46, and the other end of the adjustment spring 47 is fixedly connected to the pressing platform 443.

[0047] It needs to be explained that when the hole of the anchor port is sealed, the downward pressure generated by the adjusting ring 42 acts on the upper pressure platform 442 through the pressure platform 43, causing the blocking platform 441 to slide down and thus release the seal on the valve channel 45. When the seal on the valve channel 45 is released, firstly, the excess mortar generated during the grouting process can flow into the shell 3, preventing the dripping of excess mortar and saving mortar. The mortar in the anchor hole can be squeezed and exhausted through the control mechanism 5 to improve the grouting effect of the mortar. Secondly, when the sealing of the next anchor port is completed, the mortar in the shell 3 can be discharged back into the anchor hole through the control mechanism 5 to avoid waste of mortar.

[0048] After the grouting of the anchor hole is completed, the shell 3 is lifted, and the ring 42 is adjusted to restore its initial state under the action of the annular spring. At the same time, under the action of the adjusting spring 47, the blocking platform 441 is brought into contact with the valve channel 45 through the pressing platform 443, and the sealing is completed, thereby preventing the mortar in the shell 3 from being lost.

[0049] As a preferred embodiment, the control mechanism 5 includes: a slip ring 51, the slip ring 51 is slidingly and sealingly arranged between the housing 3 and the grouting pipe 2;

[0050] A sealing plate 53, one end of which is slidably disposed on the grouting pipe 2, and the other end of which is rotatably disposed on one end of a connecting rod 52, and the other end of the connecting rod 52 is rotatably disposed on the slip ring 51;

[0051] The compression spring 54 is sleeved on the grouting pipe 2 , and one end of the compression spring 54 is connected to the slip ring 51 , and the other end of the compression spring 54 is connected to the grouting pipe 2 .

[0052] It should be noted that when the initial grouting of the anchor hole is completed and there are bubbles, the mortar flows into the shell 3 through the valve channel 45 and acts on the slip ring 51, causing the slip ring 51 to slide down and squeeze the compression spring 54. The reaction force generated by the squeezing of the compression spring 54 will act on the mortar in the anchor hole, thereby exhausting the mortar in the anchor hole through the squeezing force. After the exhaust is completed, continuous grouting will cause the slip ring 51 to fall to the limit, and at the same time compress the compression spring 54 to the limit position. At this time, the sealing plate 53 is used to cut off the grouting pipe 2 through the connecting rod 52, thereby ending the grouting of this anchor hole.

[0053] When grouting the next anchor hole, initially when the valve channel 45 is in the open state, the mortar in the shell 3 is discharged from the valve channel 45 into the anchor hole under the action of the compression spring 54. At the same time, during the grouting process, the slip ring 51 slides up, and the sealing plate 53 slides under the action of the connecting rod 52, thereby releasing the cut-off effect on the grouting pipe 2, thereby continuing to complete the grouting operation of the anchor hole.

[0054] In specific implementation, when grouting the anchor hole, the regulating mechanism 4 can not only seal the anchor hole opening to prevent the mortar from dripping and losing, thereby saving mortar, but can also cooperate with the control mechanism 5 to complete the collection of mortar and store it in the shell 3, so that it can be discharged into the new anchor hole when grouting the next anchor hole. At the same time, after the grouting is completed in the anchor hole, the control mechanism 5 can also cut off the grouting pipe 2 to prevent the mortar from overflowing due to excessive grouting, and cooperate with the regulating mechanism 4 to prevent the loss of the mortar stored in the shell 3 after the grouting is completed, further improving the utilization effect of the mortar.

[0055] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the scope of protection of the present invention.
