Description

Technical Field

[0001] This utility model belongs to the field of drilling machine technology, specifically relating to a mining adjustable angle deep hole drilling machine. Background Technology

[0002] With the continuous advancement of mining technology, deep hole drilling rigs, as important equipment in mine tunneling and ore body extraction, are widely used in deep hole drilling operations such as blasting holes and exploration holes in mines. Currently, deep hole drilling rigs for mining typically move to the work area via tracked vehicles during the drilling process, and the drilling angle is adjusted by a support device to ensure the verticality and construction accuracy of the borehole.

[0003] However, in actual mining construction environments, the terrain is complex and varied, with steep slopes and uneven ground often presenting challenges that cause the drilling rig's tracked chassis to tilt. When the drilling rig chassis is not level, traditional support devices typically only support angle adjustments in one direction, failing to provide precise, all-around adjustment of the drilling support. In such cases, achieving true vertical adjustment of the drilling equipment is difficult, affecting the accuracy and safety of drilling operations. Furthermore, existing deep-hole drilling rigs exhibit poor coordination in support frame angle adjustment and drilling depth control, making them ill-suited to different terrains and complex working conditions. This results in low drilling quality and a susceptibility to problems such as borehole deviation and collapse. Utility Model Content

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] Example 1:

[0027] like Figure 1As shown, a mining adjustable-angle deep hole drilling rig includes a tracked vehicle 1 and a hydraulic arm 2 mounted on the tracked vehicle 1. The tracked vehicle 1 adopts a wide track structure, which can adapt to complex mine terrain and ensure the stability of the drilling rig's movement. The end of the hydraulic arm 2 is equipped with a connecting seat 3 that can be adjusted to rotate in the left and right directions. The connecting seat 3 is hinged to the hydraulic arm 2 to realize multi-angle adjustment of the drilling position during drilling operations. A support frame 4 that can be adjusted to rotate in the front and back directions is rotatably mounted on the left side of the connecting seat 3. The support frame 4 is used to support the entire drilling operation assembly and can realize precise adjustment of the drilling direction of the drill rod 7 and drill bit 9 through rotational cooperation with the connecting seat 3. A drive mechanism 10 that drives the support frame 4 to rotate is fixedly mounted on the right side of the connecting seat 3. The drive mechanism 10 realizes the automatic rotation of the support frame 4 through a drive motor 101 and a gear transmission system, improving the convenience and accuracy of drilling operations.

[0028] A lifting block 6 is installed on the left side of the support frame 4. During drilling operations, the lifting block 6 is precisely raised and lowered via a guide frame 8 to ensure the verticality of the drill rod 7 and the drill bit 9, as well as the drilling depth. The drill rod 7 is installed on the lower side of the lifting block 6. The drill rod 7 is made of high-strength alloy material, which has excellent wear resistance and torsional resistance, ensuring its service life when working in hard rock formations in mines. A drilling motor 5, which drives the drill rod 7 to rotate, is fixed on the upper side of the lifting block 6. The drilling motor 5 is a high-power DC motor, which is connected to the drill rod 7 via a coupling to achieve efficient and stable power output. The drill bit 9 is fixed at the lower end of the drill rod 7. The drill bit 9 can be equipped with different types of cutting tools according to different geological conditions to improve drilling efficiency and hole quality. A guide frame 8, which drives the lifting block 6 to rise and fall, is fixed on the left side of the support frame 4. The guide frame 8 ensures the smoothness and verticality of the movement of the lifting block 6 through a guiding structure, preventing deviation during drilling.

[0029] like Figure 2 As shown, a fixing plate 42 is fixed in the middle of the support frame 4. The fixing plate 42 is a high-strength steel plate structure, which is used to strengthen the overall rigidity and stability of the support frame 4 and prevent deformation caused by stress during drilling operations. A rotating shaft 41 is fixed on the right side of the fixing plate 42 and is rotatably mounted on the connecting seat 3. The rotating shaft 41 is supported by a high-precision bearing to realize the smooth rotation of the support frame 4 in the front and back directions, which is convenient for fine adjustment of the drilling direction in complex terrain.

[0030] like Figure 3As shown, the drive mechanism 10 includes a drive motor 101 fixed to the right side of the connecting seat 3. The drive motor 101 is firmly connected to the connecting seat 3 through a flange, which can stably output rotational torque. A large gear 103 mounted on the rotating shaft 41 is coaxially installed with the rotating shaft 41 to achieve efficient power transmission. A small gear 102 that meshes with the large gear 103 is fixed on the output shaft of the drive motor 101. The small gear 102 and the large gear 103 adopt an involute tooth profile design to ensure high efficiency and low noise during transmission. The above structure realizes the automatic adjustment of the support frame 4 in the front and rear directions, which effectively improves the accuracy of drilling positioning and the convenience of operation.

[0031] like Figure 4 As shown, the guide frame 8 includes support plates 82 fixed at the upper and lower ends of the support frame 4. The support plates 82 are made of thick-walled steel plates to ensure the structural strength and durability of the entire guide frame 8. A lead screw 84 and a guide rod 83 are respectively set between the upper and lower support plates 82 near the two side edges. The lead screw 84 is the core component of the lifting mechanism and drives the lifting block 6 to achieve high-precision lifting by rotation. The guide rod 83 is fixed on the support plate 82 to provide guidance for the lifting block 6 to move up and down and prevent lateral swaying. The lead screw 84 is rotatably mounted on the support plate 82 and adopts a ball screw structure to reduce motion resistance and improve lifting stability. A lifting motor 81 that drives the lead screw 84 to rotate is fixed on the upper side of the upper support plate 82. The lifting motor 81 is connected to the lead screw 84 through a coupling to realize the automatic lifting of the lifting block 6. A guide sleeve 85 is fixed at the center of the lower support plate 82. The guide sleeve 85 is a high-strength alloy sleeve to further improve the straightness and guiding accuracy of the movement of the lifting block 6.

[0032] like Figure 5 As shown, the lifting block 6 has a threaded hole 61 that mates with the lead screw 84. The threaded hole 61 is made of high-precision internal thread processing technology to ensure a tight fit with the lead screw 84 and achieve efficient power transmission. The lifting block 6 is fixed with a guide sleeve 62 that mates with the guide rod 83. The guide sleeve 62 is made of wear-resistant alloy and works with the guide rod 83 to provide precise guidance for the lifting block 6, effectively avoiding vibration and displacement caused by loose parts during drilling operations.

[0033] like Figure 6As shown, a rotating bracket 31 is fixed on the right side of the connecting seat 3. The rotating bracket 31 adopts a thick-walled welded structure to enhance the stress performance of the connection part. A rotating cylinder 22 installed in the rotating bracket 31 is fixed on the left end of the hydraulic arm 2. The rotating cylinder 22 and the rotating bracket 31 are connected by a pin 32 that passes through it. The pin 32 is made of high-strength alloy steel and has been heat-treated to improve wear resistance and load-bearing capacity, ensuring long-term stable operation when the angle is frequently adjusted. A hydraulic rod 21 is set on the upper side of the hydraulic arm 2. The two ends of the hydraulic rod 21 are hinged to the connecting seat 3 and the hydraulic arm 2 respectively. The hydraulic rod 21 is a high-pressure hydraulic cylinder, which can provide strong and stable power to realize multi-angle and high-precision adjustment of the connecting seat 3 and the support frame 4, thereby adapting to the drilling operation needs of complex mine terrain.

[0034] Example 2:

[0035] See Figures 1-6 This embodiment employs a mining adjustable-angle deep-hole drilling rig based on automatic leveling and intelligent control. The tracked vehicle 1 travels to the drilling area via remote control or driver operation, utilizing its wide track structure to adapt to the complex ground conditions of the mining area, and achieving initial self-balancing of the vehicle body through a hydraulic suspension system. The hydraulic arm 2 is connected to the top of the tracked vehicle 1. The hydraulic arm 2 consists of multi-stage hydraulic cylinders and has multi-degree-of-freedom extension, retraction, and pitch functions, allowing for flexible adjustment of the working height and angle according to operational needs, ensuring that the drilling rig's main frame can always reach the designated position.

[0036] During operation preparation, the operator first uses the control system to slowly extend the hydraulic arm 2. The connecting seat 3 at the end of the hydraulic arm 2 rotates precisely left and right under the drive of the hydraulic rod 21. The connecting seat 3 is hinged to the hydraulic arm 2 via a built-in rotary bearing, enabling high-precision planar rotation, which in turn drives the left-side rotating support frame 4 to adjust its pitch in the forward and backward directions. The rotation of the support frame 4 is controlled by the drive mechanism 10 fixedly mounted on the right side. The drive mechanism 10 consists of a drive motor 101, a pinion 102, a gear 103, and related transmission components. The drive motor 101 outputs power, which, after meshing with the pinion 102 and gear 103, drives the rotating shaft 41 to achieve automated forward and backward rotation adjustment of the support frame 4. The entire rotation system uses a precision planetary reducer and high-strength bearings to improve the stability and durability of the adjustment process.

[0037] When encountering uneven terrain and the tracked vehicle 1 tilts, the operator controls the extension and retraction of the hydraulic rod 21, which in turn drives the connecting seat 3 to finely adjust its angle, thereby compensating for the tilt angle of the support frame 4 and ensuring that the drilling direction remains perpendicular to the ground. After leveling, the lifting block 6 moves up and down along the support frame 4 under the constraint of the guide frame 8. The guide frame 8 includes support plates 82 at the upper and lower ends, guide rods 83 on both sides, and ball screws 84. The lifting motor 81 drives the ball screw 84 to rotate, causing the lifting block 6 to descend slowly and smoothly. The lifting block 6 is tightly engaged with the ball screw 84 through the internal threaded hole 61, and the guide sleeve 62 is slidably engaged with the guide rod 83, ensuring the straightness and anti-sway capability during the lifting movement.

[0038] During drilling operations, the drilling motor 5 starts and drives the drill rod 7 and drill bit 9 to rotate at high speed via a dedicated coupling. The drill bit 9 adopts an alloy hardened cutting tip design, suitable for various complex strata such as hard rock and veins. The drill rod 7 can be connected or replaced in sections according to the working depth to ensure the needs of deep hole operations. The lower end of the drill bit 9 continuously cuts the rock strata, and the rock cuttings are discharged through the borehole gap. The lifting block 6 moves downward at a uniform speed under the guidance of the guide frame 8, realizing the continuous advancement of the drill bit 9. Throughout the drilling process, the operator can monitor the drilling depth, advance rate, support frame 4 angle, and tracked vehicle 1 attitude in real time, and adjust parameters through the integrated sensing system and human-machine interface to achieve automatic monitoring and safety protection throughout the entire process.

[0039] To further ensure safety and operational efficiency, this embodiment is equipped with a protective cover, an audible and visual alarm, and an emergency stop button. In the event of abnormal vibration, overheating, overload, or other abnormal conditions, the system can automatically shut down and issue an alarm signal to protect the safety of operators and equipment. Furthermore, all critical connection points are equipped with dustproof and waterproof structures, enhancing the reliability and lifespan of the equipment in harsh mining environments.

[0040] The working principle of this utility model is as follows:

[0041] Before drilling operations, the tracked vehicle 1 moves to the target drilling area via remote control or driving operation. Its wide track structure adapts to the complex terrain of the mining area, ensuring a smooth stop. During the preparation phase, the hydraulic arm 2 extends under the drive of the hydraulic system and is adjusted to the designated working height and initial angle. The connecting seat 3 at the end of the hydraulic arm 2 rotates left and right under the action of the hydraulic rod 21 to achieve lateral alignment of the drilling rig. A support frame 4 is rotatably mounted on the left side of the connecting seat 3. The pitch angle of the support frame 4 is adjusted by the drive mechanism 10, which consists of a drive motor 101, a pinion 102, and a gear 103. The drive motor 101 drives the pinion 102 to mesh with the gear 103, thereby driving the rotating shaft 41 to achieve precise adjustment of the support frame 4 in the front and rear directions. This adjustment process effectively eliminates the effects of uneven terrain and tilting of the tracked vehicle 1, ensuring that the support frame 4 remains vertical and guaranteeing the verticality and accuracy of the drilling operation.

[0042] After angle adjustment, the lifting motor 81 drives the lead screw 84 to rotate. The lifting block 6, through the threaded hole 61 and the lead screw 84, moves smoothly downwards along the guide rod 83 and guide sleeve 62. The drilling motor 5 is installed on the upper side of the lifting block 6, driving the drill rod 7 to rotate at high speed. The lower end of the drill rod 7 is connected to the drill bit 9. The drill bit 9 is selected according to the geological conditions and continuously cuts the rock strata through rotation to complete the drilling. Throughout the drilling process, the structure of the guide frame 8 (including the support plate 82, guide rod 83, lead screw 84, and guide sleeve 85) ensures that the movement of the lifting block 6 along the support frame 4 is always stable and reliable, effectively preventing the drill rod 7 from shaking or deviating, and ensuring the straightness of the drilling and operational safety.

[0043] During operation, all drives, adjustments and safety monitoring are monitored in real time by the equipment integrated control system. Operators can adjust the angle of the support frame 4, lifting speed and drilling parameters according to actual needs to ensure that deep hole drilling operations are carried out efficiently, safely and accurately.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
