Description

Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to a drilling device for positioning blast holes in mining. Background Technology

[0002] In mining and construction engineering, "blast hole positioning holes" typically refer to boreholes prepared for blasting operations. These holes are precisely positioned within the rock or ore body to hold explosives. Accurate positioning of blast holes is crucial for ensuring blasting effectiveness, improving blasting efficiency, and guaranteeing operational safety; therefore, blast hole positioning hole drilling equipment is required for drilling.

[0003] However, in existing technologies, traditional drilling machine support rods are usually fixed on the mounting frame. But when drilling in a mine, it is not convenient to adjust the support position of the support rod according to the terrain, thus reducing the stability of the drilling machine. During drilling operations, the drilling machine is prone to shaking and tipping, which can damage it and reduce its service life and drilling effect. Moreover, most drilling machine support rods are adjusted using screws, but the screws are exposed and dust and impurities can easily affect the adjustment effect of the screws.

[0047] In this embodiment, the limiting pin 117 is pulled out from the inside of one of the limiting holes 103, and then the push rod rectangular block 104 slides inside the annular groove 102 through the limiting block 116. The position of the threaded sleeve 110 and the adjusting screw 119 is adjusted according to the terrain of the mine to improve its support and stability. The drive motor 113 drives the drill bit 108 to drill. After adjustment, the limiting pin 117 is released. Under the elastic force of the spring 118, the limiting pin 117 is embedded inside the limiting hole 103, so that the rectangular block 104 is more stably positioned on the outer surface of the circular plate 1. The threaded sleeve 110 rotates on the outer surface of the circular shaft 115, which can drive the adjusting screw 119 to adjust the support angle and improve stability.

A positioning block 106 is fixedly installed at the bottom of the slide rod 105 to prevent the connecting blocks 109 from disengaging.

[0050] Working principle: Pulling the limiting pin 117 out of the inside of one of the limiting holes 103, the push rod rectangular block 104 slides inside the annular groove 102 through the limiting block 116. The position of the threaded sleeve 110 and the adjusting screw 119 is adjusted according to the terrain of the mine to improve support and stability. The drive motor 113 drives the drill bit 108 to drill. After adjustment, the limiting pin 117 is released. Under the elastic force of the spring 118, the limiting pin 117 is embedded inside the limiting hole 103, so that the rectangular block 104 is more stably positioned on the outer surface of the circular plate 1. The threaded sleeve 110 rotates on the outer surface of the circular shaft 115, which can drive the adjusting screw 119 to adjust the support angle and improve stability.

[0051] When the adjusting screw 119 is rotated, the annular plate 120 rotates inside the annular groove 124, causing the telescopic sleeve 111 to extend and retract for adjustment. The annular plate 120 prevents the telescopic sleeve 111 from twisting and deforming as it rotates with the adjusting screw 119. The telescopic sleeve 111 protects the adjusting screw 119 from being affected by gravel and dust generated during drilling. The rotating block 125 can drive the mounting plate 112 to adjust, making the mounting plate 112 better fit the ground, and then fix it in place. The mounting plate 112 can... To improve the stability of the adjusting screw 119 and the threaded sleeve 110, the electric push rod 101 can be turned on to drive the drive motor 113 to adjust up and down, so that the drive motor 113 can drive the drill rod 107 and the drill bit 108 to perform drilling operations. Connecting blocks 109 are fixedly installed on both sides of the drive motor 113. The connecting blocks 109 are movably sleeved on the outer surface of the slide rod 105 to position the drive motor 113 and improve the stability of the drive motor 113. A positioning block 106 is fixedly installed at the bottom of the slide rod 105 to prevent the connecting blocks 109 from disengaging.
