Description

Technical Field

[0001] The present invention relates to the technical field of drilling rigs, and specifically refers to an inclined-hole drilling rig for mines. Background Art

[0002] The inclined-hole drilling rig for mines is a type of professional equipment that plays a crucial role in the field of mine exploitation. It has a solid appearance and a compact structure, with a unique inclined-hole design. Its main purpose is to drill holes with a specific inclination angle in various media such as rocks and ores according to the mining requirements during mine exploitation operations. Whether it is the development of underground mine roadways or the preparation of blasting operations in open-pit mines, it is indispensable. By drilling precise inclined holes, it provides a basis for subsequent blasting charge loading, bolt and cable anchoring, geological exploration, etc., greatly improving the mine exploitation efficiency and effectively ensuring the safety and accuracy of exploitation operations.

[0003] In mine exploitation operations, the inclined-hole drilling rig is extremely important equipment. However, there are many inconveniences in adjusting the upward and downward inclination angles of the current inclined-hole drilling rigs for mines. From the perspective of structural design, the angle adjustment mechanisms of some drilling rigs are relatively complex. The traditional mechanical adjustment method often requires operators to manually rotate multiple components such as screws and nuts, which is a cumbersome and time-consuming process. For example, during the operation of an open-pit mine, in order to cooperate with a new blasting plan, it is necessary to frequently adjust the upward inclination angle of the drilling rig. Each operation by the workers takes nearly half an hour, seriously affecting the exploitation progress. Moreover, after long-term high-intensity use of this complex structure, problems such as component wear and jamming are likely to occur, further increasing the adjustment difficulty and maintenance cost. From the analysis of the operation process, there is a lack of convenient angle indication and precise control devices. When adjusting the angle, operators mostly rely on experience and simple tools such as spirit levels, and it is difficult to accurately control the angle. In the narrow space of underground mines, poor lighting further increases the operation difficulty. For example, in the underground exploitation of a lead-zinc mine, due to inaccurate angle adjustment, the drilling position deviated, not only wasting a large amount of manpower and material resources for rework, but also affecting the overall exploitation plan. In addition, different workers have different understandings and operating habits of angle adjustment, which also makes it difficult to ensure the consistency and accuracy of angle adjustment. Summary of the Invention

[0004] In order to solve the above various problems, the present invention proposes an inclined-hole drilling rig for mines that is convenient for adjusting the upward and downward inclination, can drill holes with a more appropriate angle, and at the same time improves the stability during the angle adjustment process.

[0005] To solve the above technical problems, the technical solution proposed by the present invention is: an inclined-hole drilling rig for mines, comprising:

[0006] Main frame, with multiple support legs provided at the bottom of the main frame. The support legs are connected to the main frame through hydraulic telescopic devices; the angle of the main frame is adjustable;

[0007] Drilling power structure, including a motor, a gearbox, and a drill rod drive shaft. An installation block is hingedly provided on the main frame. The motor and the gearbox are arranged on the installation block. The motor is connected to the input shaft of the gearbox through a coupling. The output shaft of the gearbox is coaxially and fixedly connected to the drill rod drive shaft. A bayonet connector is provided at the front end of the drill rod drive shaft for connecting the drill rod;

[0008] Oblique opening guiding structure, arranged on the main frame, including an electric double-shaft telescopic structure and a guiding block. A placement space for placing the drill rod drive shaft is provided in the guiding block. Ball bearings in contact with the drill rod drive shaft are provided on both the front and rear sides of the placement space.

[0009] Preferably, the electric double-shaft telescopic structure includes a reciprocating lead screw connected to the main frame. A cylinder is connected to the nut seat of the reciprocating lead screw. The extending end of the cylinder is connected to the guiding block.

[0010] Preferably, rollers are connected to the bottom of the support legs.

[0011] Preferably, the main frame includes two parts, a plate body and a support frame. The support frame and one side of the plate body are connected through a rotating seat. A hydraulic cylinder for adjusting the angle between the plate body and the support frame is provided on the side away from the rotating seat.

[0012] Preferably, the bottom of the hydraulic cylinder is hinged to the plate body, and the extending end of the hydraulic cylinder is hinged to the support frame.

[0013] Preferably, the support frame is a hollow wedge-shaped structure that gradually thins from one side to the other.

[0014] Preferably, a wavy built-in support plate is provided in the hollow part of the support frame.

[0015] The advantages of the present invention compared with the prior art are as follows:

[0016] Convenient angle adjustment: The main frame is connected by a rotating seat between the plate body and the support frame, and the angle is adjusted by the hydraulic cylinder hinged between the two. By controlling the injection volume of hydraulic oil, the included angle between the plate body and the support frame can be quickly changed. Whether tilting upward or downward, it can quickly respond to the drilling requirements in the mine, and can accurately adjust the angle even in narrow underground spaces, creating favorable conditions for drilling.

[0017] Precise Angle Control: Compared with traditional methods, this solution uses a hydraulic cylinder, enabling operators to precisely control its telescopic amount, allowing the main frame to reach the required tilt angle, meeting the high-precision requirements for drilling angles in mining operations and improving the drilling quality.

[0018] Enhanced Adjustment Stability: The articulated design of the hydraulic cylinder with the plate body and support frame can evenly disperse the working force, preventing the structure from deforming and being damaged due to uneven stress during adjustment, ensuring the relative movement between the plate body and the support frame is stable, guaranteeing the normal operation of the drilling power and the inclined opening guiding structure at different angles, and improving the stability of angle adjustment.

[0019] Inclined Opening Guiding Assistance: The electric double-axis telescopic device of the inclined opening guiding structure includes a reciprocating lead screw, a nut seat, and a cylinder that can be flexibly adjusted as needed to quickly adjust the position of the guiding block. The balls in the guiding block contact the drill pipe drive shaft, reducing friction and stabilizing the guiding. During drilling after angle adjustment, it ensures the best guiding of the drill pipe and improves the stability of the drilling angle. Description of the Drawings

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] An inclined opening drilling rig for mines includes:

[0029] The main frame is provided with a plurality of support legs 1 at the bottom, and the support legs 1 are connected to the main frame through hydraulic telescopic devices; the angle of the main frame is adjustable;

[0030] The drilling power structure includes a motor 2, a gearbox 3, and a drill pipe drive shaft 4. An installation block 5 is hingedly provided on the main frame. The motor 2 and the gearbox 3 are arranged on the installation block 5. The motor 2 is connected to the input shaft of the gearbox 3 through a coupling 6. The output shaft of the gearbox 3 is coaxially and fixedly connected to the drill pipe drive shaft 4. A bayonet connector 7 is provided at the front end of the drill pipe drive shaft 4 for connecting the drill pipe;

[0031] The bevel - mouth guiding structure is arranged on the main frame and includes an electric double - shaft telescopic structure and a guiding block 8. A placement space 9 for placing the drill pipe drive shaft 4 is provided in the guiding block 8. Ball bearings 10 in contact with the drill pipe drive shaft 4 are provided on both the front and rear sides of the placement space 9.

[0032] Combined with attached Figure 2 Regarding the design of the electric double - shaft telescopic structure, which includes a reciprocating lead screw 11, a nut seat, and a cylinder 12, it has significant advantages. The reciprocating lead screw 11 can accurately convert the rotational motion of the motor into a linear motion, making the movement of the guiding block 8 smoother and precisely controllable. By connecting the cylinder 12 through the nut seat, and the extending end of the cylinder 12 is connected to the guiding block 8, this combination not only enhances the flexibility of adjustment but also can meet the adjustment requirements of the position of the guiding block 8 under different working conditions. For example, in complex geological conditions, according to the actual needs of drilling, the position of the guiding block 8 can be quickly adjusted to ensure that the drill pipe drive shaft 4 is always in the best guiding state, thereby improving the accuracy and efficiency of drilling.

[0033] Combined with attached Figure 1 Regarding the design that a roller 13 is connected below the support leg 1, this greatly improves the mobility of the equipment. In the mining operation environment, it is often necessary to move the drilling rig according to the progress of mining and the change of the drilling position. The presence of the roller 13 enables the drilling rig to move conveniently and quickly within the mining site without the need for additional handling equipment, saving labor and time costs. For example, in an open - pit mine, the drilling rig can be easily moved to different mining areas for drilling operations, improving the usage efficiency and flexibility of the equipment.

[0034] Combined with attached Figure 2, the main body frame is connected by a rotating seat between the plate body 14 and the support frame 15, and the angle between the two is adjusted by a hydraulic cylinder. This structural design makes the angle adjustment of the main body frame simple and efficient. The bottom of the hydraulic cylinder is hinged to the plate body 14, and the extending end is hinged to the support frame 15, which can provide a powerful driving force to change the included angle between the plate body 14 and the support frame 15. Compared with the traditional angle adjustment method, this design can achieve more precise angle control and can quickly adapt to the drilling requirements at different inclination angles. For example, in the narrow space of an underground mine, the angle of the main body frame can be flexibly adjusted according to the trend of the roadway and the drilling requirements, creating favorable conditions for the drilling operation.

[0035] Combined with the attached Figure 2 , the connection method where the bottom of the hydraulic cylinder is hinged to the plate body 14 and the extending end is hinged to the support frame 15 further optimizes the stability and reliability of the angle adjustment. This hinged method can evenly disperse the force generated during the operation of the hydraulic cylinder, avoiding structural deformation or damage caused by uneven force. During the process of adjusting the angle of the main body frame, it can ensure the smooth relative movement between the plate body 14 and the support frame 15, thus ensuring that the drilling power structure and the inclined port guiding structure can work properly at different angles, improving the overall performance and service life of the equipment.

[0036] Combined with the attached Figure 1 and the attached Figure 2 , the support frame 15 is designed as a wedge-shaped structure that is hollow and tapers from one side to the other, which has multiple advantages. The hollow structure reduces the overall weight of the equipment, facilitating handling and installation, and saving material costs while ensuring the structural strength. The wedge-shaped structure is conducive to placing and fixing the equipment under different terrain conditions and can better adapt to the complex ground conditions of the mine. For example, on a sloping hillside or an uneven mine ground, the wedge-shaped support frame 15 can provide more stable support, preventing the equipment from sliding or tilting and ensuring the safe progress of the drilling operation. The hollow part of the support frame 15 is provided with a corrugated internal support plate 16, and this design significantly enhances the structural strength of the support frame 15. The corrugated internal support plate 16 can effectively disperse the pressure acting on the support frame 15 and improve its load-bearing capacity. Even when under a large load, such as when the drill rig is performing high-intensity drilling operations, the support frame 15 can remain stable, not easily deformed or damaged. This not only ensures the normal operation of the equipment but also extends the service life of the equipment, reduces the frequency of maintenance and replacement of components, and lowers the usage cost.

[0037] Working principle: First, push the drill rig to the predetermined drilling position. Thanks to the rollers 13 connected to the bottom of the support leg 1, the drill rig can move easily within the mine site. After reaching the designated location, start the hydraulic telescopic device on the support leg 1 and extend it until the support leg 1 firmly touches the ground, lifting the drill rig to ensure its stability during operation. According to the actual drilling requirements of the mine, the angle of the main frame needs to be adjusted. The main frame is composed of a plate body 14 and a support frame 15 connected by a rotating seat. During operation, control the hydraulic cylinder. Since the bottom of the hydraulic cylinder is hinged to the plate body 14 and the extending end is hinged to the support frame 15, when hydraulic oil is injected into the hydraulic cylinder, its extending end pushes the support frame 15 to rotate around the rotating seat, thereby changing the angle between the plate body 14 and the support frame 15. In the narrow space of an underground mine, the angle can be accurately adjusted according to the roadway trend and drilling requirements, creating favorable conditions for subsequent drilling operations. After the angle of the main frame is adjusted, prepare the drilling power structure. The motor 2 and the gearbox 3 are installed on the mounting block 5 hinged on the main frame. Start the motor 2, and the output shaft of the motor 2 drives the input shaft of the gearbox 3 to rotate through the coupling 6. After being speed-changed by the gearbox 3, the output shaft of the gearbox 3 drives the drill rod drive shaft 4 to rotate coaxially. At the front end of the drill rod drive shaft 4, connect the drill rod firmly using the bayonet connector 7 to provide power for drilling.

[0038] The beveled mouth guiding structure is used to ensure drilling accuracy. The reciprocating lead screw 11 in the electric double-shaft telescopic structure is driven by a motor to rotate, and the rotational motion is converted into linear motion through the nut seat. The nut seat is connected to the cylinder 12, and the extending end of the cylinder 12 is connected to the guiding block 8. Under complex geological conditions, according to the actual drilling needs, the rotational speed and stroke of the reciprocating lead screw 11, as well as the telescopic amount of the cylinder 12, can be adjusted to quickly adjust the position of the guiding block 8. The guiding block 8 is provided with a placement space 9 for placing the drill rod drive shaft 4, and the ball bearings 10 on the front and rear sides of the placement space 9 are in contact with the drill rod drive shaft 4, which can not only reduce the friction when the drill rod drive shaft 4 rotates but also provide stable guidance for the drill rod drive shaft 4 during drilling, ensuring that it is always in the best guiding state and improving drilling accuracy. After everything is ready, start the drill rig for drilling operations. The motor 2 continuously provides rotational power for the drill rod drive shaft 4, and the drill rod cuts the rock during rotation. At the same time, by controlling the electric double-shaft telescopic structure, the guiding block 8 is adjusted in a timely manner according to the drilling depth and rock changes to ensure the stable drilling of the drill rod. During drilling, the operator needs to closely monitor the drilling situation, such as the drilling progress and the operating state of the drill rod. After drilling is completed, first turn off the motor 2 to stop the rotation of the drill rod drive shaft 4. Then, operate the electric double-shaft telescopic structure in reverse to return the guiding block 8 to its initial position. Next, control the hydraulic cylinder to contract to restore the angle of the main frame to its initial state. Finally, retract the hydraulic telescopic device on the support leg 1 and use the rollers 13 to move the drill rig to the next working location or storage area to complete the current drilling operation process.
