[0029] The use process of the angle-edge-angle hole arrangement positioner for mining blasting drilling
[0030] Preparation
[0031] Calculate the angle: According to the open-pit bench blasting perforation design scheme (such as the relevant parameters of the triangular hole arrangement method) and the trigonometric function relationship, the degree of the base angle of the isosceles triangle is calculated.
[0032] Adjust the angle of the positioner: operate the angle-side-angle hole arrangement positioner, turn its adjusting arm 3 to the degree position of the base angle of the isosceles triangle calculated, and use the characteristics of the adjusting arm 3 and the fixed arm 4 that are rotationally connected and can maintain the position after rotation and indicate the angle of the included angle to accurately complete the angle adjustment with the help of the indicating gap 7. At the same time, according to the characteristics of the locking piece (locking bolt 5 and nut) that is threadedly connected through the corresponding through holes of the protractor 1, the fixed arm 4, and the adjusting arm 3, the adjusting arm 3 is fixed to the required angle to ensure the stability of the included angle between the adjusting arm 3 and the fixed arm 4.
[0033] Positioning process
[0034] Place the positioner: place the two angle-adjusted angle-side-angle hole arrangement positioners on the two existing fixed points respectively, and use the stable support structure brought by the fixed connection of the fixed arm 4 and the protractor 1 to ensure that the positioner is placed stably and accurately.
[0035] Emit laser: turn on the first infrared laser emitter 2 and the second infrared laser emitter 6 on the positioner. The first infrared laser emitter 2 is coaxial with the fixed arm 4, and the axis of the fixed arm 4 passes through the axis of the protractor 1, ensuring that its emission direction is accurate and stable; the second infrared laser emitter 6 is coaxial with the adjusting arm 3, and the axis of the adjusting arm 3 passes through the axis of the protractor 1, so that its emission direction changes accurately with the rotation of the adjusting arm 3. Then adjust the laser appropriately to make the laser accurately aim at the corresponding point respectively.
[0036] Determine the new triangle point: according to the angle-side-angle theorem of a triangle, the intersection of the first infrared laser emitted from the first infrared laser emitter 2 on the two fixed arms 4 and the second infrared laser emitted from the second infrared laser emitter 6 connected to the two adjusting arms 3 determines the new triangle point, realizing accurate hole arrangement positioning.
[0037] Repeat the operation to complete the hole arrangement work
[0038] At the first row of hole positions, move the position of the adjusting positioner according to the design requirements, and repeatedly perform the operations of "emitting laser" and "determining triangle point" to determine all the triangle points required in the entire blasting area one by one, completing the hole arrangement work. In this process, since the protractor 1 adopts a semicircular structure, it can meet the angle measurement range requirement of 0° to 180° to adapt to different hole arrangement requirements, and the structure is simple and light, facilitating the carrying and operation of on-site technical personnel.
[0039] AsFig. 2 As shown, in particular, it is known that the open-pit bench blasting perforation design is a triangular hole arrangement method, the hole spacing is 9m, the row spacing is 7m, 3 rows of holes are arranged, and the on-site technical personnel have completed the arrangement of the first row of holes by measuring the rope. According to the design scheme and the related trigonometric function relationship, the base angle of the isosceles triangle is calculated as 57.26°. Operate the two hole positioners, and adjust the angle adjusting arms 3 of both to 57.26°. Ensure that the angle of the adjusting arm 3 is accurately set, and prepare for subsequent positioning of the hole arrangement point using the angle-side-angle theorem. Place the two hole positioners on the already arranged point 2 and point 3 respectively, and ensure that the device is stable and the position is accurate and error-free during the placement process, so as to ensure that the positioner can function normally. Stable positioner placement is an important basis for ensuring the accuracy of laser emission direction and the accuracy of subsequent point determination. Turn on all the infrared laser emitters on the positioner, and then adjust appropriately so that the emitted laser accurately aims at point 2 and point 3 respectively. Precise laser aiming can ensure the pointing accuracy of the two lasers, and in turn ensure the accuracy of the intersection point (triangle point) positioning. According to the angle-side-angle theorem, the intersection position of the second infrared laser lines emitted from the second infrared laser emitters 6 of the two positioners is the triangle point that needs to be calibrated, and the positioning of a new triangle point is completed. The angle-side-angle theorem can be used to accurately find the third point based on the existing two points and the set angle.
[0040] The principle and implementation mode of the specific examples in the utility model are described, and the above embodiment is only used to help understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
