Drilling machine capable of rapidly and accurately locating

Abstract

The invention discloses a drilling machine capable of rapidly and accurately locating. The drilling machine comprises a drilling machine under frame and a power head part, and is characterized by being provided with a chassis and a tray fixedly welded with the drilling machine under frame; the chassis takes a rectangular frame as a base; a pair of longitudinal lateral frames arranged in parallel on the rectangular frame forms a longitudinal track; a pair of horizontal tracks arranged in parallel can move longitudinally along the track on the longitudinal track; a drilling machine platform is supported on the horizontal tracks, and can move horizontally along the tracks on the horizontal tracks; and the tray is supported on the drilling platform through a turntable bearing, and can rotate 360 degrees horizontally on the drilling machine. The invention has simple, easy, convenient and accurate location and easy operation.

Description

technical field [0001] The invention relates to a drilling rig, more specifically, it is used in the construction of underground water exploration drilling holes and drainage holes in coal mines. Background technique [0002] At present, in the construction process of underground water exploration and discharge drilling holes and drainage holes in coal mines, there are common problems such as frequent movement and stabilization of drilling rigs, complex positioning procedures and large errors, long time occupation, and large errors in the location, orientation, inclination and design of drilling holes. It causes problems such as low drilling efficiency and large deviation between the final hole position and the actual position. The specific performance is as follows: [0003] 1. The chassis width of the traditional drilling rig is 800mm. Once the drilling rig is stabilized, it can only drill holes with the same orientation and different inclination angles. If the drilling o...

AI Technical Summary

Problems solved by technology

Once the drilling rig is stabilized, it can only drill holes with the same orientation and different inclination angles. If the drilling orientation is slightly changed, the drill must be moved, positioned, and stabilized. It takes 2 to 3 hours to move, locate, and stabilize the drill once. It all depends on the hoist, and the labor intensity is high. If the drilling rig deviates during the drilling process, it will be very difficult to adjust the drilling rig, and it will take longer to increase the labor intensity of the drilling construction.

[0004] 2. When stabilizing the drilling rig, the base of the drilling rig is narrow, and the pressing column is sometimes limited by the site conditions. The pressing column is not solid, and the drilling rig is prone to move during drilling, causing the drilling rig to be unsteady and easily causing accidents in the hole; and The inner-injection hydraulic press column is frequently lifted and lowered, and the hydraulic components are easily damaged, resulting in automatic unloading, etc.

[0005] 3. When moving the next drilling hole, it is necessary to remove the press column and move the drilling rig again for stabilization. The entire drilling rig must be hoisted with a chain hoist, causing many safety hazards, high labor intensity, and a lot of time-consuming, etc.

[0006] 4. There is no scale set on the drilling rig itself, so it is difficult to realize visualization

The orientation of the drilling depends on the middle line of the roadway and the angle is dialed by the degree ruler, and the inclination of the drilling is measured by the degree ruler on the runway. Due to the site conditions and human factors, the error is large, which leads to the deviation of the drilling hole during construction, resulting in the actual construction. The drilled hole deviates greatly from the designed drilled hole
