Description

Technical Field

[0001] The utility model relates to the technical field of slope anchoring, in particular to an anchoring positioning auxiliary device. Background Art

[0002] When the slope slides or has already caused a landslide, slope reinforcement is an important method to solve this problem. Among the slope reinforcement methods, anchor cable (anchor rod) reinforcement is the most important and common reinforcement method. When working on the mine slope reinforcement, the anchor cable (anchor rod) must be constructed according to the designed incident direction, otherwise the anchor cable (anchor rod) reinforcement effect will be affected, and safety hazards will arise. In the actual construction process, the incident direction of the anchor cable (anchor rod) is mainly determined by the compass, and the traditional compass relies on the geomagnetic field to calibrate the direction, but the ore body is often magnetic, and the motor of the anchor drill is also magnetic. These high-frequency magnetic fields will interfere with the compass and make it impossible to read accurately, which will eventually lead to deviations in the incident direction of the anchor cable (anchor rod), affecting the construction quality.

[0003] The invention patent with patent number CN202111028102.0 discloses an anchor arm precision guidance system and an anchor trolley using the system, which includes an anchor arm and a drilling arm, on which a three-dimensional electronic compass for measuring the direction of the borehole relative to the frame is installed. The three-dimensional electronic compass accurately measures the direction of the borehole relative to the frame; guides the anchor arm to finally accurately position, and accurately inserts the anchor into the borehole. However, the scheme still cannot avoid the interference of the high-frequency magnetic field formed by the ore body and the anchor drill motor on the compass, and thus cannot ensure that the anchoring angle will not deviate and affect the construction quality.

[0004] Based on this, there is an urgent need to provide an anchor positioning auxiliary device that can effectively eliminate the interference of the high-frequency magnetic field formed by the ore body and the anchor drill rig motor to the positioning compass, and ensure that the positioning compass normally receives the low-frequency geomagnetic field to achieve precise positioning.

[0018] The utility model arranges two good conductor mounting parts on both sides of the positioning compass in the plane direction of the positioning compass. Based on the low conductivity characteristics of the good conductor mounting parts, when the frequency of the interference electromagnetic field is high, the eddy current generated in the low resistivity good conductor is used to form a counteracting effect on the external electromagnetic waves.

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0028] The present invention provides an auxiliary anchoring device. Figures 1 to 5 As shown, the anchoring positioning auxiliary device is installed on the anchoring operating table of the anchoring drilling rig, which includes a positioning compass 1 and a positioning compass 1 mounting assembly. The positioning compass 1 mounting assembly includes a non-conductor mounting part 2 and a good conductor mounting part 3. The positioning compass 1 is installed on the non-conductor mounting part 2, and the good conductor mounting part 3 is arranged on both sides of the positioning compass 1 in the plane direction of the positioning compass 1.

[0029] The anchoring operation table and the drill arm are turned synchronously. By installing the anchoring positioning auxiliary device on the anchoring operation table of the anchoring drilling rig, the positioning compass 1 changes at the same angle as the drill arm. By monitoring the angle change of the positioning compass 1, the anchoring component is adjusted to perform construction according to the designed incident direction to ensure the stability of the anchoring, thereby ensuring the safety of the construction project. Preferably, the positioning compass 1 in the anchoring positioning auxiliary device is fixed on the extension line of the axis of the drill arm through the positioning compass 1 mounting assembly.

[0030] The good conductor mounting part 3 has low conductivity. When the frequency of the interfering electromagnetic field is high, the eddy current generated in the low resistivity good conductor is used to form a counteracting effect on the external electromagnetic waves. Therefore, the good conductors located on both sides of the positioning compass 1 can form a high-frequency magnetic field shield on both sides of the positioning compass 1, effectively eliminating the interference of the high-frequency magnetic field formed by the ore body and the anchor drill motor on the positioning compass 1. At the same time, the good conductors located on both sides of the positioning compass 1 do not form a closed electromagnetic shielding field, which can ensure that the positioning compass 1 can normally receive the low-frequency geomagnetic field to achieve precise positioning.

[0031] like Figure 1 As shown, the good conductor mounting member 3 is a metal cantilever parallel and symmetrically arranged on both sides of the positioning compass 1, and its metal material is preferably copper or aluminum. In order to prevent the good conductor mounting member 3 from interfering with the positioning compass 1 receiving the low-frequency geomagnetic field, the two good conductors are at least 80cm to 150cm apart.

[0032] The two ends of the non-conductor mounting member 2 are respectively fixedly connected to the two good conductor mounting members 3, so as to set the positioning compass 1 between the two good conductors. Figure 1 and Figure 3 As shown, a non-conductor mounting platform 4 is provided in the middle of the non-conductor mounting member 2, a leveling bubble cavity 41 and a compass mounting groove 42 are provided on the non-conductor mounting platform 4, and the positioning compass 1 is installed in the compass mounting groove 42. Before monitoring the anchoring direction, the positioning compass 1 needs to be horizontally positioned, and the position of the leveling bubble in the leveling bubble cavity 41 is adjusted so that the leveling bubble is located in the exact center of the leveling bubble cavity 41, which means that the positioning compass 1 is in a horizontal position at this time.

[0033] Specifically, a horizontal fine-tuning member 43 is provided at the bottom of the non-conductor mounting platform 4 to adjust the position of the leveling bubble so that it is located at the horizontal center. At least three horizontal fine-tuning members 43 are provided at the bottom of the non-conductor mounting platform 4. Figure 3 As shown, a platform base 5 is provided below the non-conductor mounting platform 4, and the platform base 5 is fixedly arranged in the middle of the non-conductor mounting member 2, and the middle of the lower end of the non-conductor mounting platform 4 is mounted on the platform base 5 through a fulcrum support member 51. Figure 3 and Figure 4 The fulcrum support 51 can be a support column hingedly arranged with the middle part of the lower end of the non-conductor mounting platform 4, or a support spring arranged between the middle part of the lower end of the non-conductor mounting platform 4 and the platform base 5, so as to provide support force for the non-conductor mounting platform 4 without affecting the change of its azimuth angle. Preferably, the non-conductor mounting member 2, the non-conductor mounting platform 4 and the platform base 5 are all made of wood or plastic.

[0034] The horizontal fine-tuning member 43 is threadedly matched from bottom to top through the platform base 5 and abuts against the lower end of the non-conductor mounting platform 4 to support the outer edge of the lower end of the non-conductor mounting platform 4. Figure 3 and Figure 5 As shown, four horizontal fine-tuning members 43 are provided at the bottom of the non-conductor mounting platform 4, each of which includes an adjusting bolt 431 and a hinge 432. The upper end of the hinge 432 is connected to the lower end vertex of the non-conductor mounting platform 4, and the lower end of the hinge 432 is provided with a bearing. The adjusting bolt 431 is threadedly matched from bottom to top through the platform base 5, and the end is sleeved on the bearing of the hinge 432. The position of the horizontal bubble is adjusted by the four horizontal fine-tuning members 43 located at the four vertex corners of the lower end of the non-conductor mounting platform 4, so as to realize the horizontal positioning adjustment of the positioning compass 1.

[0035] Furthermore, a fixing portion 6 is provided at the end of the good conductor mounting member 3, and the positioning compass 1 is fixed to the anchoring operating table through the fixing portion 6 to avoid the problem of deviation in the positioning angle caused by unstable manual holding. At the same time, to facilitate the disassembly and assembly of the anchoring positioning auxiliary device, a magnet 61 is embedded on the fixing portion 6, so that the anchoring positioning auxiliary device can be magnetically attracted to the anchoring operating table; when it is necessary to anchor another anchoring drilling rig, the anchoring positioning auxiliary device can be directly removed from the anchoring operating table of the anchoring drilling rig and magnetically mounted on another anchoring drilling rig for use.
