Description

Technical Field

[0001] The invention relates to the technical field of drilling positioning, and in particular to a liftable positioning drill for coal mine drilling. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. Coal is the main solid fuel and a type of combustible organic rock. It is formed by lush plants that grow in a certain geological age. In a suitable geological environment, it gradually accumulates into thick layers and is buried under water or in mud. It is formed by natural coalification over a long geological period. In open-pit coal mining, drilling and blasting are essential processes. During drilling and blasting, the layout of the drilling positions is the key work before drilling. The quality of drilling and blasting directly affects the overall production of open-pit mines. The layout of the drilling positions is the first step before drilling. Whether the drilling rig can be constructed according to the design is mainly determined by the accurate layout of the drilling positions.

[0003] After searching, a coal mine drilling positioning device proposed for the Chinese patent (application number: CN202322739665.1) includes: a base, an adjustment column is installed on the base, an adjustment slot is opened on the adjustment column, a servo motor is installed on the end of the adjustment column away from the base, and an adjustment rod is fixed on the output end of the servo motor, and the adjustment rod is located in the adjustment slot. In the coal mine drilling positioning device, the servo motor drives the drill rod to be adjusted forward and backward on the adjustment frame through the docking seat, the docking seat can be fixed on the adjustment frame by tightening the locking bolt, and the adjustment frame can be adjusted on the beam frame by the adjustment seat. At the same time, the adjustment seat can be locked on the beam frame by the insertion rod and the limit hole. The above method is conducive to the servo motor driving the drill rod to adjust the forward and backward and left and right displacements. After the position adjustment is completed, it is also convenient to perform stable positioning and locking, which is conducive to accurate drilling of the specified position, and improves the working efficiency and drilling stability of drilling.

[0004] However, the above-mentioned device still has certain shortcomings: in the prior art, although simple drilling operations can be achieved, due to the complex and changeable coal mining environment, limited space, and frequent operations in narrow tunnels, the size of the equipment has become a crucial consideration. In order to ensure that the equipment can be easily moved and transported in coal mines, the prior art usually designs the drilling equipment into a more compact model. However, due to the small overall volume, the stability of the equipment during the drilling process is difficult to ensure. In drilling operations, stability is crucial, which is directly related to the accuracy, depth and efficiency of drilling. If the equipment shakes or becomes unstable during the drilling process, it will not only lead to a decrease in the quality of drilling, but may also cause safety accidents, thereby seriously affecting the construction quality and progress. During the drilling process, the equipment often shakes, causing the drilling direction to deviate from the predetermined trajectory and the drilling depth to fail to reach the expected level. This not only increases the difficulty of subsequent mining, but also leads to a lot of waste of time and resources. In addition, insufficient stability will also damage the equipment itself and shorten the service life of the equipment.

[0005] Therefore, we have made improvements to this and proposed a liftable coal mine drilling positioning drill to solve the above-mentioned problems. Summary of the invention

[0048] like Figure 1-5 As shown, as a preferred embodiment, on the basis of the above method, further, the side wall of the third sliding frame 220 is also fixedly connected to the extrusion rod 223 symmetrically arranged about the drill bit 222, the two groups of extrusion rods 223 are respectively slidably connected to the two groups of second sliding frames 210, and the outer wall of the extrusion rod 223 is also sleeved with a third elastic member 224.

[0049] like Figure 1-3 As shown, as a preferred embodiment, on the basis of the above method, further, the top wall of the mounting frame 20 is also fixedly connected to a lifting motor 230, and the inner wall of the mounting frame 20 is also rotatably connected to a lifting screw 231, the lifting screw 231 is threadedly connected to the third sliding frame 220, the output end of the lifting motor 230 passes through the mounting frame 20 and is fixedly connected to the lifting screw 231, and the end of the lifting screw 231 away from the lifting motor 230 passes through the mounting frame 20 and is fixedly connected to a gear 232.

[0050] like Figure 1-7 As shown, as a preferred embodiment, on the basis of the above method, further, the inner wall of the mounting frame 20 is rotatably connected to a rotating drum 240, the inner wall of the rotating drum 240 is fixedly connected to a cleaning brush 241 that cooperates with the drill bit 222, and the outer wall of the rotating drum 240 is fixedly connected to a gear ring 242 that meshes with the gear 232.

[0051] like Figure 1-7 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the inner wall of the body 10 is fixedly connected to a push handle 110, and the side wall of the push handle 110 is rotatably connected to an electric telescopic rod 111 symmetrically arranged about the central axis of the body 10, and the output end of the electric telescopic rod 111 is rotatably connected to the mounting frame 20, and the two side walls of the body 10 are rotatably connected to the wheel hub 112, and the outer wall of the push handle 110 is also provided with a control panel 113, and the control panel 113 is electrically connected to the drilling motor 221, the electric telescopic rod 111, the impact drill 134 and the lifting motor 230.

[0052] It should be noted that the stiffness coefficients of the third elastic member 224 , the second elastic member 145 , and the first elastic member 121 decrease in sequence.

[0053] Specifically, when the liftable positioning drill for coal mine drilling is used: the drill is moved to the position where drilling is required, the drill is not started at this time, the drill is in the initial state, the drilling component and the support component are in the standby state, the first sliding rod 120 and the support frame 130 in the lifting part are in the initial position, and the first elastic member 121, the second elastic member 145 and the third elastic member 224 are in the uncompressed state;

[0054] When drilling is required, the control panel 113 is used to control the electric telescopic rod 111 to adjust the deflection angle of the mounting frame 20 relative to the machine body 10, thereby achieving the purpose of adjusting the drilling angle. After the adjustment is completed, the lifting motor 230 is started to drive the lifting screw 231 to rotate. Since the lifting screw 231 is threadedly connected to the third sliding frame 220, the rotation of the lifting screw 231 can make the third sliding frame 220 move downward along the first sliding groove 201, thereby driving the drilling motor 221 and the drill bit 222 to move downward. At the same time, the drilling motor 221 is started and drives the drill bit 222 to start rotating.

[0055] When the third sliding frame 220 slides downward, since the stiffness coefficient of the third elastic member 224 is greater than that of the first elastic member 121, the second sliding frame 210 is driven to slide downward by the extrusion rod 223 and under the action of the third elastic member 224, and the support rod 152 is driven to press the first sliding frame 151 to move downward through the linkage rod 211 and the linkage ring 153. Since the elastic stiffness of the second elastic member 145 is greater than that of the first elastic member 121, the support rod 152 is pressed downward along with the movement of the first sliding frame 151, the first elastic member 121 is compressed, and the universal wheel 142 gradually contacts the ground. At the same time, the impact drill 134 is started and penetrates into the ground to complete the rigid fixation of the support frame 130 to the ground, thereby increasing the accuracy of drilling and significantly improving the stability during the drilling process, ensuring that the drill bit 222 maintains a stable posture during drilling, reducing deviations caused by vibration or external interference, thereby improving the accuracy and safety of drilling, and through the lifting support component, while improving the overall stability, it will not affect its portability and ease of use.

[0056] At the same time, as the drill bit 222 continues to move downward, since the support frame 130 stops moving after moving into position, the first sliding frame 151 continues to slide downward along the fixed rod 150, and pushes the first connecting rod 143 to move through the third connecting rod 154, and the first connecting rod 143 and the second connecting rod 144 drive the telescopic support rod 140 to extend from the support frame 130. At this time, the second elastic member 145 is stretched and can be extended in time according to actual needs after the first fixing member completes the initial fixation, and is additionally connected or supported with the ground or a nearby stable structure. This design not only increases the redundancy and stability of the system, but also effectively disperses the pressure and vibration generated during the drilling process, and reduces the potential risks caused by overloading of a single fixed point.

[0057] After drilling is completed, the lifting screw 231 moves in the opposite direction, and drives the rotating drum 240 to rotate through the gear 232 and the gear ring 242, and drives the cleaning brush 241 to rotate, and cleans the debris and dust remaining on the outer wall of the drill bit 222, thereby extending the service life of the drill bit 222 and improving the efficiency and accuracy of the drilling operation.

[0058] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings.

Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0059] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
