Description

Technical Field

[0001] This invention relates to the field of borehole positioning technology, specifically a borehole positioning device for mining drilling rigs. Background Technology

[0002] In mining operations, drilling rig positioning plays a crucial role. Whether it is ore extraction, tunnel excavation, or geological exploration, drilling operations are indispensable. Accurate drilling positioning ensures that the borehole reaches the predetermined target location, laying a reliable foundation for subsequent blasting, mining, and other work.

[0003] Patent application CN202410444383.5 discloses a drilling positioning device for a mining drilling rig, comprising: a movable frame with a limiting plate on it, a rotating block rotatably mounted on the limiting plate, a drill rod inside the rotating block, the rotation of the rotating block driving the drill rod to rotate synchronously around the central axis of the rotating block, and ratchet teeth connected to both ends of the rotating block, the two ratchet teeth rotating in opposite directions; a sliding plate slidably connected to a limiting plate, and a first return spring being provided between the sliding plate and the limiting plate, and a groove being provided on the side wall of the sliding plate to engage with the ratchet teeth.

[0004] In summary, during drilling operations in mines, the moving frame is prone to vibration and movement under the reaction force of the drilling process, which may lead to deviations in the drilling position. In addition, the geological structure of mines is diverse and uncertain, such as the development of rock joints and fissures, and the large differences in hardness between different rock layers. During the drilling process, when the drill bit encounters a weak rock layer, it may deflect, resulting in borehole displacement.

[0016] Compared with the prior art, the present invention provides a drilling positioning device for mining drilling rigs, which has the following beneficial effects:

[0017] 1. This invention provides a drilling positioning device for a mining drilling rig. When drilling is performed in a mine, a support mechanism is used to support the bottom of the moving frame, thereby increasing the stability of the drilling mechanism during drilling operations and preventing drilling position deviations that may occur due to movement of the moving frame during drilling. Furthermore, when the drill bit encounters a weak rock layer during drilling, the drill rod is positioned by a fixed shaft to prevent displacement of the drill hole.

[0018] 2. By setting up a support mechanism, the first drive motor drives the first rotating frame to slide along the top outer wall of the moving frame via the drive wheel. During the deflection of the first rotating frame, the second protrusion at the bottom of the first connecting rod applies a squeezing force to the first protrusion at the top of the sliding frame, causing the sliding frame to slide downward, thereby increasing the contact area between the bottom of the moving frame and the ground, thus improving the stability during drilling operations.

[0019] 3. The present invention improves the accuracy of drilling operations by setting up an adjustment mechanism, using a second drive motor to drive the second fixed block to rotate, using a first dual-axis motor to cause the first rotating rod to rotate, using a second dual-axis motor to cause the second rotating rod to rotate, and using a third drive motor to adjust and position the second rotating frame.

[0020] 4. By setting up a drilling mechanism, after the drilling position is determined, the connecting frame is pushed towards the drilling position using the second hydraulic rod. The servo motor performs drilling operations through the drill rod. The fixed shaft improves the stability of the connecting frame during movement through the fixed frame. At the same time, the fixed shaft can prevent the drill rod from deviating when encountering soft rock layers. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Example 1: See Figures 1-3The present invention provides a technical solution: a drilling positioning device for a mining drilling rig, comprising a support mechanism 1, the support mechanism 1 including a movable frame 101, a first connecting shaft 104 fixedly connected to the bottom of the movable frame 101, a caster wheel 105 fixedly connected to the end of the first connecting shaft 104 away from the movable frame 101, a sliding frame 106 provided at the bottom of the movable frame 101, a groove 102 formed on the top outer wall of the movable frame 101, and a first through hole 103 formed on the bottom outer wall of the movable frame 101, and further comprising:

[0034] The adjustment mechanism 2 includes a first rotating frame 201 slidably connected to the top outer wall of the movable frame 101. A first drive motor 202 is fixedly connected to the inner wall of the first rotating frame 201. A drive wheel 203 is fixedly connected to the output end of the first drive motor 202. The drive wheel 203 is rotatably connected to the inner wall of the groove 102. A first fixing block 209 is fixedly connected to the top outer wall of the first rotating frame 201. A sliding block 211 is slidably connected to the inner wall of the first fixing block 209. A second through hole 210 is opened in the inner wall of the first fixing block 209. The inner wall of the first rotating frame 201 is fixedly connected to... The first connecting rod 204 is fixedly connected to the inner wall of the first rotating frame 201 by the first hydraulic rod 207. The top of the first rotating frame 201 is equipped with a drilling mechanism 3. When drilling is carried out in the mine, the support mechanism 1 supports the bottom of the moving frame 101, thereby improving the stability of the drilling mechanism 3 when drilling and avoiding the movement of the moving frame 101 during the drilling process, which may cause the drilling position deviation. In addition, during the drilling process, when the drill bit encounters a weak rock layer, the drill rod 309 is positioned by means of the fixed shaft 308 to prevent the drilling from shifting.

[0035] The inner wall of the sliding frame 106 is slidably connected to the first connecting shaft 104. A first protrusion 107 is fixedly connected to the outer wall of the sliding frame 106 near the moving frame 101. A spring 108 is fixedly connected to the top outer wall of the sliding frame 106. The spring 108 is used for the reset function of the sliding frame 106. The end of the spring 108 away from the sliding frame 106 is fixedly connected to the moving frame 101. The first drive motor 202 drives the drive wheel 203, so that the first rotating frame 201 slides on the top outer wall of the moving frame 101. When the first rotating frame 201 deflects, the second protrusion 206 at the bottom of the first connecting rod 204 will exert a squeezing effect on the first protrusion 107 at the top of the sliding frame 106, causing the sliding frame 106 to slide downward, thereby increasing the contact area between the bottom of the moving frame 101 and the ground, thereby improving the stability during the drilling operation.

[0036] The working principle of this embodiment is as follows: When drilling is carried out in the mine, firstly, the first drive motor 202 drives the drive wheel 203, causing the first rotating frame 201 to slide along the top outer wall of the movable frame 101. When the first rotating frame 201 deflects, the second protrusion 206 at the bottom of the first connecting rod 204 applies a pressing force to the first protrusion 107 at the top of the sliding frame 106, causing the sliding frame 106 to slide downward. During this process, the second connecting shaft 205 slides on the inner wall of the first through hole 103, making the movement of the sliding frame 106 more stable, thereby increasing the contact area between the bottom of the movable frame 101 and the ground. At the same time, the universal wheel 105 at the bottom of the movable frame 101 allows the movable frame 101 to move.
