Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a drilling equipment for blasting in open-pit mines. Background Technology

[0002] Mineral resource mining refers to the mining of solid metal and non-metal deposits, including open-pit mining of surface ore bodies and shallow ore bodies, as well as underground mining of blind mines and deep ore bodies. When mining in open-pit mines, it is necessary to drill holes in the rock. Drilling equipment refers to the use of tools that are harder and sharper than the target object to cut or squeeze through rotation. In mining drilling operations, the stable operation of the drilling machine is crucial.

[0003] The following technologies are required for the practical application of mining drilling machines:

[0004] Power technology: Provide sufficient and stable power to drive the drill bit for drilling operations, such as by using a suitable power source like an electric motor or engine;

[0005] Drilling technology: This includes the design and selection of drill bits to ensure effective breaking of different geological media such as rocks; and drilling processes, such as the control of parameters like drilling speed and pressure applicable to different formations.

[0006] Positioning and guiding technology: accurately determines the drilling position and angle, and keeps the drill bit moving in the predetermined direction during the drilling process to ensure drilling accuracy;

[0007] Traditional drilling machines often lack effective support structures during drilling, which makes the equipment prone to vibration and reaction forces during operation. This not only threatens the safety of operators but may also affect the accuracy and stability of drilling, thereby affecting the blasting effect and construction quality. Utility Model Content

[0024] This application provides a drilling device for blasting in open-pit mines, which effectively solves the technical problem that traditional drilling machines often lack effective support structures during drilling, leading to vibration and reaction forces during operation. This not only threatens the safety of operators but may also affect the accuracy and stability of drilling, thereby affecting the blasting effect and construction quality.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application aims to effectively address the problem that traditional drilling machines often lack effective support structures during drilling, leading to vibrations and reaction forces during operation. This not only threatens the safety of operators but may also affect the accuracy and stability of drilling, thereby impacting blasting effects and construction quality. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a drilling device for blasting in open-pit mines, including a drilling machine 21. Handles 22 are fixedly installed on both sides of the drilling machine 21. A drill rod 25 is provided at the lower end of the drilling machine 21. Four fixing blocks 24 are equidistantly fixedly installed on the circumferential surface of the drilling machine 21, each fixing block 24 having an installation hole 23. An installation sleeve 16 is fitted onto the lower end of the drilling machine 21, and four locking pins 18 are equidistantly fixedly installed on the installation sleeve 16, each locking pin 18 being fitted onto the fixing block 24. Within the mounting hole 23, a fixed shaft 17 is fixedly mounted through the side end of the mounting sleeve 16. Two support rods 11 are rotatably mounted through the fixed shaft 17. When the drilling machine 21 is drilling into the mine, the user connects the drill rod 25 to the drilling machine 21, and then connects the two handles 22 on the drilling machine 21 to the gas cylinder and air pump to drill into the mine. Before drilling, the mounting sleeve 16 can be slipped onto the lower end of the drilling machine 21, and then inserted into the fixed block 2 through the triangular block design at the upper end of the four locking pins 18. Within the mounting hole 23, the inclined design of the locking block 18 allows it to lock after entering the mounting hole 23 of the fixing block 24. At this point, the mounting sleeve 16 is fixedly connected to the drilling machine 21. When drilling, to support the drilling machine 21, simply place the lower end of the support rod 11 in contact with the ground. Simultaneously, the user can loosen the locking screw 13 according to the drilling angle, then rotate the two support rods 11 to a suitable angle. Tightening the locking screw 13 secures the support rod 11, allowing it to be fixed at multiple angles. This new device, by adding an mounting sleeve 16 and two support rods 11 to the drilling machine 21, enables the two support rods 11 to provide support for the movement of the drilling machine 21 during drilling, thus preventing injury to operators from equipment vibration and reaction forces during drilling, ensuring a stable drilling direction and position, and avoiding impacts on blasting effectiveness and construction quality.

[0028] A connecting rod 12 is fixedly installed between two support rods 11. A locking screw 13 is threaded through the connecting rod 12. A fixed round rod 14 is fixedly installed on the mounting sleeve 16. A high-friction groove 15 is opened on the fixed round rod 14. The upper end of the locking screw 13 fits into the high-friction groove 15 opened on the fixed round rod 14. When drilling without auxiliary support frame, simply press the four locking blocks 18 toward the center point of the drilling machine 21, so that the four locking blocks 18 can be moved out of the mounting hole 23 opened in the fixed block 24. At this time, the mounting sleeve 16 can be removed from the drilling machine 21. The present invention, through the setting of four locking blocks 18 and fixed block 24, enables the auxiliary support mechanism of the device to be quickly disassembled and assembled when in use or not, which greatly improves the efficiency of the mechanism.

[0029] Working principle:

[0030] In the first step, when drilling into the mine, the user connects the drill rod 25 to the drilling machine 21, and then connects the two handles 22 on the drilling machine 21 to the gas cylinder and air pump. Before drilling, the mounting sleeve 16 can be slipped onto the lower end of the drilling machine 21. Then, through the triangular block design at the upper end of the four locking blocks 18, it can be inserted into the mounting hole 23 opened in the fixing block 24. Due to the inclined design of the locking blocks 18, they can be locked after entering the mounting hole 23 opened in the fixing block 24. At this time, the mounting sleeve 16 is fixedly connected to the drilling machine 21. When it is necessary to support the drilling machine 21 during drilling, simply bring the lower end of the support rod 11 into contact with the ground to support the drill. The drilling machine 21 is supported. Simultaneously, the user can loosen the locking screw 13 according to the drilling angle, then rotate the two support rods 11 to a suitable angle, and finally tighten the locking screw 13 to fix the support rods 11. This allows for fixation of the support rods 11 at multiple angles. This new invention, through the installation sleeve 16 and two support rods 11 added to the drilling machine 21, enables the two support rods 11 to provide support for the movement of the drilling machine 21 during drilling, thereby preventing injury to operators from equipment vibration and reaction forces during drilling, and ensuring a stable drilling direction and position, thus avoiding impacts on blasting effects and construction quality.

[0031] The second step involves pressing the four locking blocks 18 toward the center of the drilling machine 21 when drilling without the need for an auxiliary support frame. This allows the four locking blocks 18 to be moved out of the mounting holes 23 in the fixing block 24, at which point the mounting sleeve 16 can be removed from the drilling machine 21. This new invention, through the four locking blocks 18 and the fixing block 24, enables the auxiliary support mechanism on the device to be quickly assembled and disassembled when in use or not, greatly improving the efficiency of the mechanism.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
