Embodiment 1

[0037] like Figures 1~6 As shown, an underground powerhouse rock anchor beam drilling positioning device includes a platform 2, and a hole positioning device is provided on the platform 2, and the hole positioning device is a plurality of side-by-side guide bushings 101, the plurality of side-by-side The guide casing 101 is connected by a synchronous connection device 7, and a drilling rig mounting frame 6 is arranged on the guide casing 101. With this structure, the mobile drilling positioning device is improved on the basis of the "sample frame method" positioning device. , First, a guide casing is added to ensure the drilling accuracy, which is beneficial to the effect of light explosion and the quality of the bolt. The function of multiple side-by-side guide casings 101 is that a drilling rig can be positioned in the side-by-side guide casings 101. When drilling, the guide casing 101 is connected through the synchronous connection device 7 to better synchronously adjust t...

Embodiment 2

[0048] Further illustrate in conjunction with embodiment 1, as Figures 1~6 As shown in the figure, the bench 2 is manufactured, and is manufactured in parts according to the design drawings in the manufacturing workshop. The components are bolted together and pre-assembled for testing. After the acceptance is passed, the parts are numbered. The bench 2 is installed and installed according to the measurement and positioning. After being accurately adjusted in place, the anchor bars are installed on the rock wall to fix the 3 and the bench 2 to be reliably connected to ensure stability. The guide casing 101 is installed and corrected, and the guide casing 101 is installed and corrected according to the drilling position measured and calibrated to ensure the accuracy of its positioning and guidance. For drilling operations, the drilling rig mounting frame 6 is used to drill along the guide casing. , in order to ensure the accuracy of drilling, the gantry 2 moves, after completin...

Embodiment 3

[0050] Further illustrate in conjunction with embodiment 1 and 2, as Figures 1~6 As shown, the platform 2 is installed to the position of the rock platform 4, and after being accurately adjusted in place, the anchor bars 3 are installed on the rock wall of the rock platform 4, which are reliably connected with the platform 4 to ensure stability, and the hole positioning device is installed. Install the hole positioning device at the corresponding position of the drilled hole in the rock table 4, fix the support frame 105 on the table 2, and hinge the connecting shaft with the horizontal frame of the table 2. After the installation of the hole positioning device is completed, adjust the hole positioning device. The guide sleeve 101 is adjusted according to the measured position, angle and direction of the borehole, and the first angle plate 106 is adjusted to drive the angle of the guide sleeve 101 up and down. The angle is fixed in the hole. After adjusting the upper and lowe...

Abstract

The invention discloses an underground workshop rock anchor beam drilling positioning device and a using method thereof. The device comprises a rack, a hole positioning device is arranged on the rack,the hole positioning device is a plurality of guide sleeves arranged side by side, the plurality of parallel guide sleeves are connected through a synchronous connecting device, a drilling machine mounting frame is arranged on the guide sleeve, the drilling positioning is accurate, the drilling quality is facilitated, the drilling efficiency is effectively improved, the blasting effect is guaranteed, the labor intensity of drilling workers is reduced, labor and cost can be effectively saved, mounting and moving are convenient, moving and in-place of the rack can be rapidly achieved, the working efficiency is greatly improved, and the device is suitable for being used and popularized.

Description

technical field [0001] The invention relates to the field of mobile positioning of drilling holes for excavation of upper and lower straight walls and inclined rock platforms of rock anchor beams of underground powerhouses, in particular to a drilling positioning device for rock anchor beams of underground powerhouses and a method of using the same. Background technique [0002] During the excavation and support of the rock anchor beams of the underground powerhouse, the "prototype method" is usually used to locate the drilling holes, that is, according to the excavation design angle of the inclined rock platform, a scaffold is set up behind the excavation surface as a drilling sample frame. Drilling holes are positioned to meet the drilling quality requirements, but there are still the following deficiencies in actual operation: it is difficult to accurately ensure the drilling hole direction, which affects the effect of light explosion; due to the high design specifications...
