DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0028] In the above description of the utility model, it should be noted that the orientation or position relationship indicated by the terms "one side", "the other side", etc. is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the term "same" does not mean that the mechanisms must be absolutely identical, but slight differences are allowed. The term "vertical" simply means that the positional relationship between the mechanisms is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0030] See also Figure 1 , the utility model provides a technical solution: a reusable anchor cable drilling plugging device, comprising a bottom plate 1 and a fixing rod 2 fixed on the bottom plate 1, the fixing rod 2 is used to anchor the bottom plate 1 on the slope;

[0031] The base plate 1 is provided with a clamping assembly for fixing the anchor cable harness.

[0032] When the reusable anchor cable drilling plugging device of the utility model is in use, when the drill hole of the slope support design experimental hole is plugged, the anchor cable extending out of the drill hole is passed through the clamping assembly of the utility model, and the base plate 1 is anchored on the slope through the fixing rod 2. After the anchoring is completed, the single-strand anchor cable harness is clamped and fixed respectively by the clamping assembly, and the fixing rod 2 can be used as a fulcrum to cooperate with the sling to pull the entire plugging device along the slope direction to ensure the stability of the installation of the plugging device, thereby realizing the plugging of the drill hole and the fixation of the anchor cable extending out of the drill hole, so as to replace the test pier formed by casting steel bars and concrete in the prior art to plug the drill hole, shortening the experimental construction period, reducing the use of steel bars and concrete, saving construction costs, and the plugging device of the utility model can be disassembled and reused after the experiment, and the installation and disassembly are more convenient, reducing the construction workload.

[0033] See also Figure 1 and Figure 2 In this embodiment, the clamping assembly includes a clamping tube 3, and a plurality of through holes 4 for the single-strand anchor cable harness to pass through are respectively opened on the clamping tube 3, and a group of clamping plates 5 are symmetrically arranged in each of the through holes 4, and a pushing component for pushing the two clamping plates 5 to clamp the single-strand anchor cable harness is provided on the clamping tube 3.

[0034] In the present scheme, when the drill hole of the slope support design experimental hole is blocked, the single-strand anchor cable harness is passed through the multiple through-holes 4 respectively. After the through-holes are passed, the blocking device of the utility model is fixedly installed on the slope, and then the two clamps 5 in each of the through-holes 4 are pushed together by the pushing component to clamp and fix the single-strand anchor cable harness in the through-holes 4, so as to fix the anchor cable extending out of the drill hole, prevent the anchor cable from retracting, and accurately control the tension force, etc., so that the transmission of the tension force is more direct and effective, which is conducive to achieving the prestress value required by the design, and the fixation of the single-strand anchor cable harness by clamping and fixing the single-strand anchor cable harness separately is more firm and stable than fixing the anchor cable harness as a whole.

[0035] See also Figure 2 and Figure 4In this embodiment, the clamping cylinder 3 is provided with a plurality of mounting holes 6 respectively connected with the through-holes 4, the diameter of the mounting holes 6 is larger than the diameter of the through-holes 4, the pushing component includes a pushing member 7 rotatably connected to the mounting holes 6, the end face of the pushing member 7 is provided with a positioning ring (not shown), the positioning ring matches the positioning groove in the mounting hole 6, which is conducive to positioning and installing the pushing member 7, and at the same time supports the rotation of the pushing member 7, the inner surface of the pushing member 7 protrudes inward to form a protrusion 8, and the protrusion 8 is sloped, and a driving mechanism is provided on the clamping cylinder 3, when the plurality of pushing members 7 rotate simultaneously under the drive of the driving mechanism, the protrusion 8 squeezes and pushes the two clamping plates 5 to enclose and clamp the single-strand anchor cable harness.

[0036] In this solution, when fixing a single-strand anchor cable harness, the driving mechanism simultaneously drives multiple pushers 7 to rotate, and the rotation of the pushers 7 drives the raised portion 8 to rotate synchronously. During the rotation process, the raised portion 8 squeezes and pushes the two clamps 5 to enclose and clamp the single-strand anchor cable harness.

[0037] See also Figures 1 to 4 In this embodiment, the outer surface of the pushing member 7 is the transmission part 9, so that the pushing member 7 as a whole is similar to a gear shape. The driving mechanism includes a mounting tube 10 mounted on the outside of the clamping tube 3, and the mounting tube 10 is fixed on the bottom plate 1. The outer circumferential surface of the clamping tube 3 is fixedly connected with two sealing plates 20 at intervals. The sealing plates 20 are circular, and an inner gear ring 21 is rotatably connected between the two sealing plates 20. A sealing ring is installed at the connection between the sealing plate 20 and the inner gear ring 21 to ensure the sealing of the connection. The inner gear ring 21 is meshed with the transmission part 9, and a driving pair for driving the inner gear ring 21 to rotate is provided on the mounting tube 10.

[0038] An oil supply channel 14 is formed between the mounting cylinder 10, the inner gear ring 21 and the two sealing plates 20. The drive pair includes a plurality of blades 15 arranged in a circumferential array on the outer circumferential surface of the inner gear ring 21. An oil pipeline 16 is arranged on the mounting cylinder 10. One end of the oil pipeline 16 is located outside the mounting cylinder 10, and the other end of the oil pipeline 16 extends into the oil supply channel 14, and the liquid outlet of the oil pipeline 16 faces the surface of the blade 15.

[0039] In this solution, the hydraulic oil is delivered to the oil supply channel 14 through the cooperation of the hydraulic pump and the oil delivery pipeline 16. Since the outlet of the oil delivery pipeline 16 is directly opposite to the surface of the blade 15, when the hydraulic oil enters the oil supply channel 14, the hydraulic oil impacts the blade 15 to drive the inner gear ring 21 to rotate between the two sealing plates 20. When the inner gear ring 21 rotates, the transmission parts 9 of the plurality of pushers 7 are all engaged with the inner gear ring 21, and the inner gear ring 21 rotates. The rotation can drive multiple pushing members 7 to rotate at the same time. When the pushing members 7 rotate, the protrusions 8 are driven to rotate synchronously. During the rotation process, the protrusions 8 squeeze and push the two clamps 5 to enclose and clamp the single-strand anchor cable harness. After the single-strand anchor cable harness is clamped and fixed, the hydraulic pump continues to provide hydraulic oil. When the oil pressure in the oil supply channel 14 reaches a preset value, the safety valve opens and cooperates with the return oil pipe (not shown) to release the pressure. The specific pressure relief process is relatively mature in the prior art and will not be described in detail here.

[0040] See also Figure 1 and Figure 2 In this embodiment, the clamping plate 5 includes a clamping portion 51 and a pushing portion 52. The clamping portion 51 is located in the through hole 4 and is used to clamp and fix the single-strand anchor cable harness; one end of the pushing portion 52 is fixedly connected to the clamping portion 51, and the other end of the pushing portion 52 extends into the mounting hole 6 and is slidably connected to the clamping tube 3. A limiting rod can be passed through the pushing portion 52 to ensure that the two clamping plates 5 can slide toward each other and will not be separated from the clamping tube 3 under the action of the limiting rod.

[0041] In this solution, when the pushing member 7 rotates, the protrusion 8 first contacts the pushing portion 52, and as the pushing member 7 rotates, the pushing portion 52 gradually squeezes the pushing portion 52 to slide toward the through hole 4, thereby pushing the two clamping portions 51 together to enclose and clamp the single-strand anchor cable harness.

[0042] See also Figure 3 In this embodiment, the mounting cylinder 10 includes a cylinder body 101 and a cylinder neck 102. The opening diameter of the cylinder neck 102 is smaller than the outer diameter of the cylinder body 101. The inner wall of the cylinder body 101 fits with the outer circumferential surface of the sealing plate 20. The outer circumferential surface and the inner circumferential surface of the sealing plate 20 are both provided with sealing rings to ensure the sealing of the connection between the sealing plate 20 and the cylinder body 101 and the clamping cylinder 3. The inner wall of the cylinder neck 102 contacts the outer surface of the clamping cylinder 3.

[0043] In the present solution, when the clamping cylinder 3 is installed in the mounting cylinder 10, the outer surface of the clamping cylinder 3 contacts the inner surface of the cylinder neck 102, so that the sealing device of the utility model has a more compact structure. Moreover, since the opening diameter of the cylinder neck 102 is smaller than the outer diameter of the cylinder body 101, when the clamping cylinder 3 is installed in the mounting cylinder 10, a certain distance is left between the clamping cylinder 3 and the cylinder body 101, thereby providing space for installing the inner gear ring 21 and setting the oil supply channel 14.

[0044] See also Figure 1 In this embodiment, the base plate 1 includes a third plate body 13, a second plate body 12 and a first plate body 11, whose areas increase step by step. A support member 17 for supporting the second plate body 12 is provided at the right angle formed by connecting the second plate body 12 and the first plate body 11, and the support member 17 is L-shaped.

[0045] In the present solution, the base plate 1 is composed of a multi-layer plate structure to improve the structural strength of the base plate 1, and since the areas of the third plate 13, the second plate 12 and the first plate 11 increase step by step, the support member 17 can be installed on the plate with a larger area to support the upper plate, so that after the plugging device of the utility model is installed on a slope, the bottom of the plate can be supported to ensure the stability between the structures of the plugging device.

[0046] See also Figure 1 In this embodiment, a nut 18 is fixedly connected to the surface of the first plate body 11 , and a fixing bolt 19 is threadedly connected to the nut 18 , and the screw end of the fixing bolt 19 extends into the second plate body 12 .

[0047] In this solution, the nut 18 and the fixing bolt 19 are installed on the plate with a larger area, and the fixing bolt 19 is screwed into the upper plate structure with a smaller area, so as to connect the two plate structures and further ensure the stability of the connection between the sealing device structures.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
