Description

Technical Field

[0001] This utility model belongs to the technical field of mineral mining equipment, and in particular relates to an open-pit mine drilling rig with automatic lifting function. Background Technology

[0002] In open-pit mining operations, drilling rigs are key equipment for drilling operations. The adjustment of the drill rod height is crucial for adapting to different drilling depths and geological conditions. Traditional open-pit mining drilling rig lifting mechanisms mostly use screws to adjust the height of the drill rod. This adjustment method can, to a certain extent, achieve precise control of the drill rod height and meet basic drilling operation requirements.

[0003] However, in actual drilling operations, the open-pit mine environment is complex, and a large amount of gravel will be splashed around the drilling rig during drilling. During the high-speed splashing process, these gravel can easily adhere to the screw used to adjust the height of the drill rod. Because the screw surface is covered with gravel, it will change the fit between the screw and related components, such as causing problems such as jamming and increased wear in the threaded fit between the screw and the slider, which will seriously affect the adjustment of the drill rod height. Utility Model Content

[0004] This utility model provides an open-pit mine drilling rig with automatic lifting function, aiming to solve the problem mentioned in the background art that when the lifting mechanism of the traditional open-pit mine drilling rig uses a screw to adjust the height of the drill rod, the debris splashed around during drilling operations easily adheres to the screw, causing changes in the fit between the screw and related components, resulting in thread jamming, increased wear, and thus seriously affecting the adjustment of the drill rod lifting.

[0005] To solve the above problems, this utility model is implemented as follows: an open-pit mine drilling rig with automatic lifting function, comprising: a drilling rig body and a mounting frame mounted on the drive arm of the drilling rig body; a drill rod for drilling, mounted on one side of the mounting frame; a one-way screw rotatably mounted in the mounting frame, with a slider threaded onto the one-way screw for lifting the drill rod; an L-shaped plate fixedly mounted on one side of the slider, the L-shaped plate being positioned above the drill rod; an arc-shaped baffle fixedly mounted in the mounting frame for protecting the one-way screw, the arc-shaped baffle covering one side of the one-way screw and slidably connected to the slider; a drive mechanism mounted on the mounting frame and the one-way screw for driving the one-way screw to rotate; and a protective mechanism mounted on one side of the mounting frame for preventing rock fragments from splashing.

[0006] Preferably, a mounting base is rotatably mounted on the L-shaped plate, and a fastening bolt is threaded onto the mounting base. The fastening bolt is threadedly connected to the drill rod.

[0013] Compared with existing technologies, the open-pit mine drilling rig with automatic lifting function provided by this solution drives the rotation of the unidirectional screw through the drive mechanism, which in turn drives the slider to rise and fall, thereby realizing the lifting and adjustment of the drill rod. It can meet the needs of different drilling depths and geological conditions, and achieve precise control.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides an open-pit mine drilling rig with automatic lifting function, such as Figure 1-5 As shown, an open-pit mine drilling rig with automatic lifting function includes: a drilling rig body 1 and a mounting frame 2 mounted on the drive arm of the drilling rig body 1; a drill rod 6 mounted on one side of the mounting frame 2 for drilling; a one-way screw 3 rotatably mounted in the mounting frame 2, with a slider 4 threaded onto the one-way screw 3 for lifting the drill rod 6; an L-shaped plate 5 fixedly mounted on one side of the slider 4, the L-shaped plate 5 being positioned above the drill rod 6; an arc-shaped baffle 8 fixedly mounted in the mounting frame 2 for protecting the one-way screw 3, the arc-shaped baffle 8 covering one side of the one-way screw 3, and the arc-shaped baffle 8 being slidably connected to the slider 4; a drive mechanism mounted on the mounting frame 2 and the one-way screw 3 for driving the one-way screw 3 to rotate; and a protective mechanism mounted on one side of the mounting frame 2 for preventing rock fragments from splashing.

[0024] In this embodiment, during operation, the drilling rig body 1 moves to a suitable position, and the drive mechanism drives the one-way screw 3 to rotate within the mounting frame 2. When the one-way screw 3 rotates, the slider 4 moves linearly along the axis of the one-way screw 3, thereby driving the L-shaped plate 5 on one side of the slider 4 to rise and fall, thereby realizing the adjustment of the drill rod 6.

[0025] During drilling, the first motor 7 is started to drive the drill rod 6 to rotate. Then, the drill rod 6 works in conjunction with the drive mechanism to drill into the ground. The arc-shaped baffle 8 protects the one-way screw 3 to prevent flying debris from adhering to the one-way screw 3 during drilling. At the same time, the protective mechanism can further prevent flying debris and protect related components.

[0026] The drive mechanism drives the one-way screw 3 to rotate, which in turn drives the slider 4 to rise and fall, thereby realizing the adjustment of the drill rod 6. This can meet the needs of different drilling depths and geological conditions and achieve precise control. The arc-shaped baffle 8 is placed on one side of the one-way screw 3 to effectively prevent splashed gravel from adhering to the one-way screw 3. This avoids the gravel from changing the fit between the one-way screw 3 and the slider 4, reducing problems such as jamming and increased wear in the threaded fit, and ensuring smooth adjustment of the drill rod 6.

[0027] In a further preferred embodiment of this utility model, a mounting base 13 is rotatably mounted on the L-shaped plate 5, and a fastening bolt is threaded onto the mounting base 13. The fastening bolt is threadedly connected to the drill rod 6. A first motor 7 for driving the drill rod 6 to rotate is fixedly mounted on the top of the L-shaped plate 5, and the output shaft of the first motor 7 is fixedly connected to the rotating shaft of the mounting base 13.

[0028] In this embodiment, when the drill rod 6 needs to rotate for drilling, the first motor 7 starts, and its output shaft drives the rotating shaft of the mounting base 13 to rotate. Since the drill rod 6 is threadedly connected to the mounting base 13 through fastening bolts, the drill rod 6 rotates to perform drilling. The arc-shaped baffle 8 continuously protects the one-way screw 3 to prevent gravel from adhering and affecting the screw's operation. The protective mechanism on one side of the mounting frame 2 also prevents gravel from splashing and protects the equipment. The first motor 7 drives the mounting base 13 to rotate the drill rod 6, ensuring efficient drilling operations. With the fastening bolts and the mounting base 13 in place, when the drill rod 6 is worn, damaged, or needs to be replaced with a different specification drill rod to adapt to different geological conditions, simply loosen the fastening bolts to remove the drill rod 6 from the mounting base 13, replace it with a new drill rod 6, and then tighten the fastening bolts again. The operation is simple and convenient.

[0029] In a further preferred embodiment of the present invention, the driving mechanism includes: a fixed plate fixedly installed on one side of the mounting frame 2; two driving wheels 9 respectively installed on the fixed plate and the top of the one-way screw 3; a belt 10 sleeved on the two driving wheels 9; and a second motor 11 fixedly installed on one side of the mounting frame 2 for driving the one-way screw 3 to rotate, wherein the output shaft of the second motor 11 is fixedly connected to the rotating shaft of the driving wheel 9.

[0030] In this embodiment, when the drill rod 6 needs to be raised or lowered, the second motor 11 is started. The output shaft of the second motor 11 drives the drive wheel 9, which is fixedly connected to it, to rotate. Since the two drive wheels 9 are connected by a belt 10, the rotation of one drive wheel 9 will drive the other drive wheel 9 to rotate synchronously, causing the one-way screw 3 to rotate. At this time, the slider 4, which is threaded onto the one-way screw 3, can only move linearly along the axial direction of the one-way screw 3 due to the restriction of the arc-shaped baffle 8, which is slidably connected to the mounting bracket 2. This drives the L-shaped plate 5 to rise or fall, and the L-shaped plate 5 in turn drives the drill rod 6 to move synchronously, thereby achieving height adjustment. By driving the one-way screw 3 to rotate through the second motor 11, the slider 4 is raised or lowered, thereby achieving height adjustment of the drill rod 6. This can meet the needs of different drilling depths and geological conditions and achieve precise control.

[0031] In a further preferred embodiment of the present invention, a protective cover 12 is fixedly installed on the top of the mounting bracket 2. The protective cover 12 covers the two drive wheels 9 to protect the drive wheels 9 and the belt 10.

[0032] In this embodiment, the protective cover 12 is installed on the two drive wheels 9, which protects the drive wheels 9 and the belt 10 and prevents debris such as flying stones from entering during open-pit mining operations.

[0033] In a further preferred embodiment of the present invention, the protective mechanism includes: a protective cover 14 disposed on one side of the mounting frame 2, the top of the protective cover 14 having a notch adapted to the drill rod 6; a drain pipe 15 fixedly installed inside the protective cover 14 for spraying water in the borehole; and a rubber cylinder 21 fixedly installed at the bottom of the protective cover 14.

[0034] In this embodiment, the drill rod 6 descends and inserts into the notch at the top of the protective cover 14 that matches the drill rod 6. Since the protective cover 14 is close to the ground, and the rubber cylinder 21 fixedly installed at its bottom contacts the ground, the soft rubber cylinder 21 effectively wraps around the ground. The debris generated during drilling is isolated by the protective cover 14 and the rubber cylinder 21, reducing debris splashing. During drilling, the drain pipe 15 is connected to the water pipe of an external water supply system, and the drain pipe 15 sprays water onto the drilling site, serving to reduce dust.

[0035] In a further preferred embodiment of the present invention, a connecting seat 16 is fixedly installed on one side of the mounting bracket 2, and a connecting block 17 is fixedly installed on one side of the protective cover 14. The connecting block 17 is inserted into the connecting seat 16, and a threaded rod 18 is threadedly installed on the connecting seat 16, with the threaded rod 18 threaded through the connecting block 17.

[0036] In this embodiment, when installing the protective cover 14, the connecting block 17 fixedly installed on one side of the protective cover 14 is inserted into the connecting seat 16 fixedly installed on one side of the mounting bracket 2. Then, the threaded rod 18 is threaded onto the connecting seat 16 and the threaded rod 18 is threaded through the connecting block 17, thereby completing the quick installation of the protective cover 14. The installation is achieved by inserting the connecting block 17 into the connecting seat 16 and then threading the threaded rod 18 through the connecting block 17. The operation is simple and quick.

[0037] In a further preferred embodiment of the present invention, the bottom of the mounting bracket 2 is provided with two buffer plates 19, and a buffer spring 20 is installed between the two buffer plates 19.

[0038] In this embodiment, when the bottom of the mounting frame 2 approaches the ground, the two buffer plates 19 located at the bottom of the mounting frame 2 first come into contact with the ground. Since a buffer spring 20 is installed between the two buffer plates 19, as the mounting frame 2 continues to descend, the buffer plates 19 will be subjected to the reaction force of the ground, causing the buffer spring 20 to contract. The contraction process of the buffer spring 20 will absorb and buffer the impact force generated when the mounting frame 2 descends, thereby playing a buffering role for the mounting frame 2.

[0039] In summary, compared with related technologies, this drilling rig, through its design that allows for rapid adjustment of drill rod height, effective protection of critical components, and reduction of rock fragmentation and dust, enables efficient, safe, and convenient drilling operations, reduces failure rates and maintenance costs, and improves operational efficiency and quality.

[0040] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art can still combine, add, delete, or otherwise adjust the features of the various embodiments of this utility model according to the circumstances without conflict or creative effort, thereby obtaining different technical solutions that do not fundamentally depart from the concept of this utility model.
