[0003] In the prior art, when installing vertical anchors, workers set up a temporary platform and manually put the resin anchor into the drilled hole. They need to use one hand to seal the hole to prevent the resin anchor from falling, and at the same time use the other hand to insert the anchor into the hole, thereby achieving the coordinated installation of the resin anchor and the anchor. However, this installation method is extremely inefficient and has a high risk factor, and workers are difficult to operate and are prone to injury.

[0004] In addition, when the resin anchor is inserted into the drill hole, there will be residual construction debris in the drill hole. If the worker inserts the resin anchor into the drill hole in the wrong direction, the resin anchor will rub against the inner wall of the drill hole, which will increase the probability of damage to the resin anchor jacket, thereby causing the resin anchor to overflow prematurely, affecting the tightening effect of the resin anchor on the anchor cable when the subsequent anchor cable is inserted.

Therefore, the above terms should not be understood as limiting the present application.

[0042] The present application is further described in detail below in conjunction with the accompanying drawings. Figures 1 to 4 illustrate.

[0043] The present application provides a resin anchor protection device 1 (hereinafter referred to as protection device 1), which is installed at the end of the resin anchor to facilitate the delivery of the resin anchor into the drill hole, and it has a protective effect on the end of the resin anchor, can reduce the probability of damage to the end of the resin anchor when inserting the drill hole, and can guide the resin anchor, so that the resin anchor can be inserted into the drill hole more smoothly, quickly and accurately, thereby improving the installation speed and improving the installation efficiency of workers installing the resin anchor.

[0044] Specifically, Figures 1 to 4 As shown, the protection device 1 of the present application includes a sleeve 11, a base 12 and a connecting plate 13. The sleeve 11 is a straight tube structure, and both ends of the sleeve 11 are provided with openings; Figure 4 As shown, the base 12 is a conical cylindrical structure, and an opening is provided at the upper end of the base 12. The upper end of the base 12 is connected to the sleeve 11, and the upper end opening of the base 12 is communicated with the lower end opening of the sleeve 11. The internal space formed by the base 12 and the sleeve 11 is used for inserting the resin anchor. Among them, since the base 12 is a conical structure, the base 12 has a good clamping effect on the end of the resin anchor, which can make the protection device 1 and the resin anchor be better fixed; at the same time, the conical structure of the base 12 can also play a guiding role when the resin anchor enters the borehole, so that the resin anchor can be inserted into the borehole more smoothly, quickly and accurately, thereby improving the installation efficiency; in addition, the base 12 and the sleeve 11 play a protective role on the end of the resin anchor, which can avoid the friction between the end of the resin anchor and the inner wall of the borehole when the resin anchor is inserted, thereby ensuring the integrity of the resin anchor before it acts with the anchor cable, which is conducive to ensuring the effective effect of the resin anchor.

[0045] Among them, Figures 1 to 3 As shown, the sleeve 11 is provided with a hollow portion 111, and the hollow portion 111 is opened on the side wall of the sleeve 11, so that after the resin anchor is broken through the outer jacket by the anchor cable, the resin anchor can overflow from the hollow portion 111 to the outside of the protective device 1, so that the resin anchor can act on the outside of the protective device 1 faster, filling the borehole, the protective device 1 and the anchor cable, and then the anchor cable, the protective device 1 and the borehole are better bonded together under the action of the resin anchor, which is beneficial to enhance the fastness of the connection of the anchor in the borehole.

[0046] Further, such as Figures 1 to 3As shown, each group of hollow parts 111 includes at least two through-holes 1111, which are rectangular or circular structures or other shaped structures. The through-holes 1111 penetrate the outer wall of the sleeve 11, and the through-holes 1111 are arranged at equal intervals. The through-holes 1111 are evenly distributed along the circumference of the side wall of the sleeve 11, which can ensure the uniformity of the overflow of the resin anchor, so that the circumferential bonding effect of the resin anchor on the protective device 1 is more uniform. In this embodiment, each group of hollow parts 111 is provided with four through-holes 1111, and the through-holes 1111 are rectangular structures. In actual use, the number, size and shape of the through-holes 1111 can be reasonably set according to needs, and they are not limited here.

[0047] Furthermore, in this application, Figure 1 , Figure 2 As shown, the base 12 includes a guide portion 122 and a connecting portion 121, one end of the connecting portion 121 is connected to the sleeve 11, and the other end of the connecting portion 121 is connected to the guide portion 122. The bottom of the guide portion 122 is a closed structure, that is, the connecting portion 121 acts between the guide portion 122 and the sleeve 11, the upper end of the connecting portion 121 is connected to the sleeve 11, and the lower end of the connecting portion 121 is connected to the guide portion 122. The connecting portion 121 is a cylindrical structure, and the guide portion 122 is a conical structure. The upper and lower ends of the connecting portion 121 have openings, and the connecting portion 121 is connected to the sleeve 11 and the guide portion 122 respectively; wherein, as Figure 2 As shown, the outer diameter of the connecting end of the connecting portion 121 and the sleeve 11 is larger than the outer diameter of the connecting end of the connecting portion 121 and the guide portion 122, that is, the outer diameter of the upper end of the connecting portion 121 is larger than the outer diameter of the lower end, and the outer wall of the connecting portion 121 is an arched curved surface convex radially outward, so that the connection between the sleeve 11 and the guide portion 122 is relatively smooth and smooth, so that the inner wall and the outer wall of the connection between the base 12 and the sleeve 11 are connected smoothly, avoiding sharp and protruding connections. On the one hand, it reduces the stress concentration of the inner wall of the connection between the base 12 and the sleeve 11 facing the resin anchor, avoiding tearing of the resin anchor protective jacket, and on the other hand, it helps to reduce the resistance of the outer side of the protective device 1, so that the protective device 1 can smoothly enter the drill hole.

[0048] like Figure 2As shown, in another optional implementation of the present application, the sleeve 11 is a straight tube structure, the outer diameter of the sleeve 11 is L3, the outer diameter of the base 12 close to the sleeve 11 is L1, and the outer diameter of the base 12 away from the sleeve 11 is L2, that is, the outer diameter of the upper end of the base 12 is L2, and the outer diameter of the lower end of the base 12 is L1, L3=L2>L1, wherein 3 / 5≤L1:L2≤4 / 5, of course, the ratio value of L1:L2 can be any one of 0.6, 0.65, 0.7, 0.75, 0.8, thereby limiting the ratio of the outer diameters between the upper and lower ends of the base 12, and limiting the conical structure of the base 12, so that the base 12 can play a better guiding role and clamping effect on the resin anchor; the ratio of L1:L2 is preferably 0.7.

[0049] like Figure 2 As shown, in another optional implementation of the present application, the axial length of the base 12 is H1, and the axial length of the sleeve 11 is H2, wherein 0.8≤H1:H2≤1. Of course, the ratio of H1:H2 can be any one of 0.8, 0.82, 0.84, 0.86, 0.88, 0.9, 0.92, 0.94, 0.96, 0.98, and 1.00. Such a structural arrangement enables the protection device 1 to save manufacturing materials to the best extent, while also ensuring that the resin anchor can be clamped when the length of the sleeve 11 and the base 12 are coordinated; in this implementation, the ratio of H1:H2 is preferably 0.92.

[0050] like Figure 2 As shown, in another optional implementation of the present application, along the axial direction, the angle θ between the outer wall of the guide portion 122 and the axis is 10° to 20°, wherein the angle θ can be any one of 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, and 20°, so that the inclination of the side wall of the guide portion 122 can ensure that the base 12 has good guiding properties while also ensuring the clamping effect of the resin anchor; in this implementation, the angle θ is preferably 14°.

[0051] In another optional implementation of the present application, the connecting plate 13 is further expanded; Figures 1 to 4As shown, the connecting plate 13 is connected to the upper end of the sleeve 11. The connecting plate 13 is a plate-like structure. There are at least two connecting plates 13. The connecting plates 13 are connected to the outer wall of the sleeve 11 at equal intervals along the circumferential direction, that is, the connecting plates 13 are connected with the same center of a circle as the center, so that each connecting plate 13 is umbrella-shaped after being connected, and the outer edges of the connecting plates 13 are on the same arc; and the intervals between the connecting plates 13 and the connecting plates 13 can allow the resin anchor to pass through, so that the resin anchor can fully contact the connecting plate 13 after overflowing, thereby increasing the connection area between the resin anchor and the connecting plate 13, thereby enhancing the connection stability between the resin anchor and the protective device 1.

[0052] Further, such as Figure 2 As shown, the angle between the connecting plate 13 and the axis is 90°, that is, the connecting plate 13 is entirely on the same plane, and the top of the connecting plate 13 is flush with the top of the sleeve 11; in this embodiment, as shown Figures 1 to 3 As shown, the connecting plate 13 includes a free end and a fixed end, the fixed end is the end of the connecting plate 13 connected to the sleeve 11, and the free end is the end of the connecting plate 13 away from the sleeve 11; Figure 2 , Figure 3 As shown, the distance between the end of the connecting plate 13 away from the sleeve 11 and the center of the sleeve 11 is greater than the radius of the sleeve 11, that is, the distance between the free end of the connecting plate 13 and the center of the sleeve 11 is greater than the radius of the sleeve 11, so that the outer edge of the connecting plate 13 exceeds the outer edges of the sleeve 11 and the base 12; and the resin anchor is inserted into the sleeve 11 and the base 12, that is, the outer edge of the connecting plate 13 exceeds the outer edge of the resin anchor. When the protective device 1 is sleeved on the end of the resin anchor, the worker inserts the resin anchor into the drill hole. Due to the connecting plate 13 The outer edge exceeds the outer edge of the resin anchor, and the connecting plate 13 blocks impurities on the inner wall of the borehole to prevent the impurities from contacting the outside of the resin anchor. At the same time, the outer edge of the connecting plate 13 preferentially contacts the inner wall of the borehole, thereby having a limiting effect on the resin anchor, which acts between the inner wall of the borehole and the outer wall of the resin anchor, and can reduce the probability of contact between the outer wall of the resin anchor and the inner wall of the borehole, thereby reducing the probability of premature damage of the resin anchor when the resin anchor is inserted into the borehole, thereby improving the immediate use effectiveness of the resin anchor.

[0053] like Figure 2 As shown, the outer diameter of the connecting plate 13 is L4, wherein the outer diameter of the connecting plate 13 is larger than the outer diameters of the sleeve 11 and the base 12, that is, L4>L3 and L4>L2; in this embodiment, the outer diameter of the connecting plate 13 is set to be larger than the sleeve 11 or the base 12, so that the outer edge of the connecting plate 13 exceeds the outer edge of the sleeve 11 and the base 12.

[0054] Furthermore, the number of connecting plates 13 is 2 to 10. In this embodiment, Figure 3As shown, the connecting plates 13 are preferably provided in 6 numbers, and the 6 connecting plates 13 are arranged equidistantly along the circumferential direction. The width of the free end is the same as the width of the fixed end, which can ensure the structural strength of the free end of the connecting plate 13; Figure 3 As shown, the outer wall of the free end of the connecting plate 13 is an arc-shaped structure, thereby ensuring that the outer edge of the corner of the free end of the connecting plate 13 is relatively smooth, thereby avoiding scratches on workers when the worker installs the protective device 1 on the end of the resin anchor. At the same time, it can avoid friction between the corner and the inner wall of the drill hole when the protective device 1 enters the drill hole, thereby avoiding damage to the protective device 1.

[0055] Further, such as Figure 2 As shown, the axial length of the connecting plate 13 is H3, wherein 1 / 25≤H3:H2≤1 / 20, and of course the ratio of H3:H2 can be any one of 0.040, 0.041, 0.042, 0.043, 0.044, 0.045, 0.046, 0.047, 0.048, 0.049, 0.050, so that the connecting plate 13 can ensure that the connecting plate 13 has sufficient structural strength within a reasonable range, while also saving material costs. In this embodiment, the ratio of H3:H2 is preferably 0.048.

[0056] Further, such as Figure 1 , Figure 3 to Figure 4 As shown, a groove 123 is provided at the bottom of the connecting plate 13. The groove 123 is circular, the center of the groove 123 is on the axis of the sleeve 11, the groove 123 is recessed toward the base 12, and the recessed depth of the groove 123 is less than the axial thickness of the bottom of the base 12. The setting of the groove 123 can increase the connection area between the bottom of the base 12 and the resin anchor, so that the connection stability between the resin anchor and the bottom of the base 12 is better, which is beneficial to the overall connection firmness of the resin anchor to the protective device 1 and the drilling hole; wherein, the inner diameter of the groove 123 is smaller than the outer diameter of the bottom of the base 12, thereby ensuring the structural strength of the bottom of the base 12.

[0057] It should be noted that the various embodiments of the present application can be arbitrarily combined into a new embodiment if the solutions do not conflict and the technical solutions can coexist.
