[0002] Blasting engineering is a project that uses explosives to break and dismantle objects. When blowing up objects, the explosives are generally placed inside the mountain to give full play to the effect of the explosives. Before placing the explosives in the mountain, it is necessary to drill holes in the mountain to form a space large enough to accommodate the explosives. When drilling a hole in the object, the drilling equipment needs to be controlled to move to the object, and the drill bit drills the object.

[0003] When the existing drilling equipment performs inclined drilling, the inclination angle is not easy to control, and the drill bit is not easy to fix when it is inclined, which will cause the drill hole to deviate from the predetermined position.

DETAILED DESCRIPTION

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Example:

[0021] A drilling device for engineering blasting, such as Figure 1 , Figure 2 and Figure 3As shown, the drill 1 includes a base and a motor. The motor drives the drill 1 to drill. The base includes a connecting block 21 with a U-shaped cross section and two supporting telescopic rods 22 welded to the bottom surface of the connecting block 21. A rotating block 3 with a U-shaped cross section is rotatably connected to the connecting block 21 in the vertical direction and fixed by a fixing member. The drill 1 is slidably connected in the rotating block 3. Slide blocks 4 are welded on both sides of the drill 1. A sliding groove 5 for sliding the slide block 4 is provided on the inner wall of the rotating block 3, and a plurality of positioning structures arranged at equal intervals are provided on the inner wall of the sliding groove 5. The sliding drill 1 drives the slide block 3 to move. The block 4 enables the slider 4 to move in the slide groove 5, and the slider 4 is fixed by a plurality of positioning structures arranged at equal intervals, so that the drill 1 can be fixed. The distance that the slider 4 slides from one of the positioning structures toward the opening direction close to the rotating block 3 to another positioning structure is the extended length of the drill 1, and the distance that the slider 4 slides from one of the positioning structures toward the opening direction away from the rotating block 3 to another positioning structure is the shortened length of the drill 1, so that the user can know and adjust the extended length or shortened length of the drill 1, so that the drill 1 can be adjusted according to needs. The drilling depth is adjusted by sliding the drill 1 because the distances between the two adjacent positioning structures are equal. The drill 1 is extended or shortened at equal distances to reduce the phenomenon that the drilling depth is too deep or too shallow. The height of the drill 1 from the ground can be adjusted by telescopically adjusting the length of the supporting telescopic rod 22. The supporting telescopic rod 22 is extended upward to drive the connecting block 21, the rotating block 3 and the drill 1 to move upward. At this time, the height required for the drill 1 to drill a hole can be increased. The supporting telescopic rod 22 is shortened downward to drive the connecting block 21, the rotating block 3 and the drill 1 to move downward. When the drill 1 is moved, the required height of the drill 1 when drilling can be shortened, so that the required height of the drill 1 when drilling can be adjusted by telescopically adjusting the support telescopic rod 22 according to the actual situation on site. When the connecting block 21 and the rotating block 3 are relatively parallel, the drill 1 is horizontally arranged relative to the ground, so that the drill 1 can drill in the horizontal direction, and the sliding block 4 and the drill 1 are driven to rotate by vertically rotating the rotating block 3. When the rotating block 3 rotates upward, it drives the drill 1 to rotate downward, so that the drilling angle of the drill 1 can be adjusted when the drill 1 rotates, making the drill 1 more widely applicable.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the positioning structure includes a plurality of positioning holes 6 which are opened on the top surface of the rotating block 3 and are arranged at equal intervals. A receiving groove 7 is opened on the top surface of the sliding block 4. A spring 8 is bonded in the receiving groove 7. A positioning block 9 which is used to be embedded in one of the positioning holes 6 is bonded to the top of the spring 8. When the drill 1 is in an idle state, the positioning block 9 is embedded in one of the positioning holes 6 in the opening direction away from the rotating block 3. Before the drill 1 slides toward the opening direction close to the rotating block 3, the positioning block 9 is first squeezed downward. In the process of squeezing the positioning block 9 downward, the spring 8 is driven to be compressed, so that the positioning block 9 is located in the slide groove 5 and the positioning block 9 can be accommodated in the receiving groove 7. Then, when the drill 1 is slid toward the opening direction close to the rotating block 3, the positioning block 9 is in conflict with the top inner wall of the slide groove 5. , and the positioning block 9 slides in the slide groove 5, and the slider 4 slides in the slide groove 5 in the direction close to the rotating block 3. At this time, the spring 8 is in the compression device until the positioning block 9 is embedded in one of the positioning holes 6 close to the opening direction of the rotating block 3. At this time, the spring 8 elastically recovers and the positioning block 9 is driven to be embedded in one of the positioning holes 6 close to the opening direction of the rotating block 3 during the upward movement of the spring 8, so that the drill 1 is fixed and the stability of the drill 1 is improved. Because the spacing of several positioning holes 6 is the same, the positioning block 9 can be separated from one of the positioning holes 6 and embedded in another positioning hole 6 to achieve equal distance extension or shortening adjustment of the drill 1, so that the user can understand and perform equal distance extension or shortening adjustment on the drill 1.

[0023] like Figure 1 As shown, two connecting plates 10 are welded on the connecting block 21, and the rotating block 3 is rotatably connected to the connecting plate 10 through a rotating shaft. The fixing piece is a bolt 11, and a threaded hole 12 is opened on the connecting plate 10. One end of the bolt 11 passes through the threaded hole 12 and presses against the side wall of the rotating block 3. When the drilling angle of the drill 1 needs to be adjusted, the drill 1 is driven to rotate by rotating the rotating block 3. At this time, the rotating block 3 rotates between the two connecting plates 10. When it is rotated to the required drilling angle, one end of the bolt 11 passes through the threaded hole 12, so that one end of the bolt 11 presses against the side wall of the rotating block 3, thereby improving the stability of the rotating block 3 during rotation adjustment.

[0024] like Figure 1 and Figure 3As shown, a handle 13 is welded to the side wall of the slider 4, and a groove 14 for the handle 13 to slide is provided on the side wall of the rotating block 3, and the groove 14 is communicated with the slide groove 5, and the length of the groove 14 is less than the length of the slide groove 5, and the length of the slide groove 5 is less than the length of the rotating block 3. The user drives the slider 4 and the drill 1 to move by holding the handle 13. At this time, the slider 4 fits the inner wall of the slide groove 5, and a part of the handle 13 is located in the groove 14, so that the handle 13 moves in the groove 14 during the movement of the handle 13, and the slider 4 moves in the slide groove 5 at the same time, so that the slider 4 and the drill 1 are conveniently moved by holding the handle 13. Because the length of the slide groove 5 and the length of the groove 14 are both less than the length of the rotating block 3, the time for opening the slide groove 5 and the groove 14 can be saved.

[0025] like Figure 1 As shown, the base also includes a bottom plate 23, and the supporting telescopic rod 22 is arranged between the bottom plate 23 and the connecting block 21. The supporting telescopic rod 22 includes a sliding rod 221 and a fixed tube 222. The fixed tube 222 is welded to the top surface of the bottom plate 23, and the sliding rod 221 is welded to the bottom surface of the connecting block 21. The sliding rod 221 is slidably connected in the fixed tube 222 and fixed by a positioning member. The positioning member is a bolt 15. A threaded hole 16 is provided on the outer wall of the fixed tube 222. One end of the bolt 15 passes through the threaded hole 16 and presses against the outer wall of the sliding rod 221. When the sliding rod 221 slides in the fixed tube 222 in a direction away from the bottom plate 23, the sliding rod 221 drives the connecting block 21, the rotating block 3 and the drill 1 to move in a direction away from the bottom plate 23, and then one end of the bolt 15 is used to move the connecting block 21, the rotating block 3 and the drill 1 in a direction away from the bottom plate 23. The bolt 221 is passed through the threaded hole 16 and one end of the bolt 221 is pressed against the outer wall of the sliding rod 221, so that the sliding rod 221 can be fixed in the fixed tube 222. At this time, the height of the drill 1 from the ground can be increased, so that the drill 1 can be used to drill some holes with higher heights. When the sliding rod 221 slides in the fixed tube 222 toward the direction close to the base plate 23, the sliding rod 221 drives the connecting block 21, the rotating block 3 and the drill 1 to move toward the direction close to the base plate 23 respectively. Similarly, one end of the bolt 221 is passed through the threaded hole 16 and one end of the bolt 221 is pressed against the outer wall of the sliding rod 221. At this time, the height of the drill 1 from the ground is shortened, so that the drill 1 can be used to drill some holes with lower heights, and the contact area with the ground can be increased through the base plate 23.

[0026] The drill 1 is made of cemented carbide, which has high hardness, strength, wear resistance and corrosion resistance, making the drill 1 more durable and having a longer service life, and better able to cope with materials of various hardness and strength, improve drilling efficiency, and reduce wear and corrosion during the drilling process.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
