Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of positioning devices, in particular to a precise positioning device for the spacing of impact-proof drilling holes. Background Art
[0002] In a rock burst mine, borehole pressure relief is often carried out to reduce the possibility of rock bursts in the mine. When carrying out pressure relief boreholes, the borehole spacing often has an important impact on the pressure relief effect. If the borehole spacing is too large, the pressure relief effect cannot be achieved; if the borehole spacing is too small, it is easy to increase the labor intensity of workers and affect economic efficiency. Therefore, when drilling blasting holes, the borehole spacing not only requires reasonable design (generally 4 meters), but more importantly, it is necessary to ensure that the borehole spacing meets the design requirements during the construction process on site.
[0003] During the underground drilling process, workers need to frequently pull the caliper to measure the borehole spacing. Moreover, during the drilling process, affected by the underground space environment and manual ruler pulling operation, it is easy to be affected by the bending of the caliper, resulting in errors in the measurement of the borehole spacing, thus making the construction of the borehole spacing inaccurate. Therefore, this application proposes a precise positioning device for the spacing of impact-proof drilling holes to solve the above problems. Content of the Utility Model

[0023] As Figure 1-2As shown in the figure, the present utility model provides a technical solution: an anti-impulse drilling spacing precise positioning device, which includes a steel ruler 1. The steel ruler 1 is processed from a channel steel with a length and width of 5.5m * 0.1m. Marking scales are provided on the steel ruler 1 for positioning the drilling spacing, and the graduation value of the marking scales is 0.1m. One end of the steel ruler 1 is connected with a fixing pin 2. The length and width of the fixing pin 2 are 0.3m and 0.05m respectively. The other end of the steel ruler 1 is connected with a lifting rod 4. The maximum telescopic height of the lifting rod 4 is 1.5m for adjusting the height of the steel ruler 1. A slider 3 for positioning is slidably arranged on the steel ruler 1. A square hole with a width of 0.05m is provided in the middle of the slider 3 and is slidably connected with the steel ruler 1. And a bolt is connected in the threaded hole arranged on the top side of the slider 3. By raising the lifting rod 4 to the drilling height, the fixing pin 2 is fixed directly below an already drilled hole. The drilling spacing is determined by moving the slider 3. After the spacing is determined, colored liquid is sprayed by the automatic nozzle connected above the slider 3 to make a mark at the drilling position. Another hole is drilled above the slider 3, so as to make the accuracy of the drilling position more precise. The bottom end of the lifting rod 4 is connected with a supporting plate 5, and the supporting plate 5 plays a role in stable support.
[0024] The operation steps of the present utility model are as follows:
[0025] By raising the lifting rod 4 to the drilling height, the fixing pin 2 is fixed directly below an already drilled hole and connected with the anchor net. The drilling spacing is determined by moving the slider 3, that is, the spacing between the slider 3 and the fixing pin 2. After the position is determined, colored liquid is sprayed by the automatic nozzle connected to the upper part of the slider 3 for marking. Another hole is drilled above the slider 3, so as to make the accuracy between the two holes higher.
