Description

Technical Field

[0001] The invention relates to the technical field of drilling holes in soft and broken surrounding rocks of mines, and in particular to a drilling device for soft and broken surrounding rocks of mines. Background Art

[0002] Drilling plays a wide range of critical roles in mining. Its emergence and development are closely linked to the evolution of mining technology and the need for safe production. Drilling stems from humanity's urgent need to exploit underground mineral resources. In the early days, as shallow mineral resources gradually depleted, people began to explore deeper underground. Ore extraction required breaking down the barrier between the ore body and the surface, which gave rise to drilling technology. Initially, drilling relied on manual labor or simple mechanical tools such as chisels and hammers, repeatedly striking holes in rock. This was extremely inefficient and labor-intensive. With the advancement of the Industrial Revolution, mechanical manufacturing technology continued to advance, leading to the emergence of mechanical equipment such as pneumatic rock drills, which greatly improved drilling efficiency and depth.

[0003] However, during drilling operations in soft and broken surrounding rock in mines, collapse and deformation are very likely to occur due to the loose rock structure and low mechanical strength. In engineering practice, mud wall protection technology is often used to maintain the stability of the borehole wall. The liquid column pressure of the mud balances the formation pressure, forming a mud skin on the borehole wall to block the surrounding rock from contact with the outside world. At the same time, mud circulation is used to carry rock cuttings. On the one hand, during the mud circulation process, the materials carried out of the borehole include large mud and rock particles, resulting in poor or even interrupted mud circulation, affecting the efficiency of drilling construction. On the other hand, these untreated large pieces of mudstone may contain harmful substances such as heavy metals. If discharged at will, they will pollute the ecological environment such as soil and water bodies around the mining area. In addition, the fine mudstone solid particles remaining in the circulating mud will aggravate the wear of the drill tool when entering the working area of the drill pipe and drill bit with the mud, shortening the service life of the drill pipe and drill bit. Summary of the Invention

[0004] The object of the present invention is to solve the problems existing in the prior art. During the drilling operation in the soft and broken surrounding rock of a mine, due to the loose rock mass structure and low mechanical strength, collapse and deformation are extremely likely to occur. In engineering practice, the slurry support technology is often used to maintain the stability of the borehole wall. The hydrostatic pressure of the slurry balances the formation pressure, and a mud cake is formed on the borehole wall to block the contact between the surrounding rock and the outside world. At the same time, the slurry circulation is used to carry rock cuttings. On the one hand, during the slurry circulation process, the substances carried out from the drill hole include large-sized mud blocks and rock blocks, resulting in poor slurry circulation or even interruption, affecting the drilling construction efficiency. On the other hand, these untreated large mudstones may contain harmful substances such as heavy metals. If discharged randomly, it will pollute the ecological environment such as the soil and water bodies around the mining area. In addition, the residual fine mudstone solid particles in the circulating slurry will aggravate the wear of the drilling tools when entering the working area of the drill pipe and the drill bit, shortening the service life of the drill pipe and the drill bit. Therefore, a drilling device for soft and broken surrounding rock in a mine is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A drilling device for soft and broken surrounding rock in a mine, including a base. Above the base, there is a drilling mechanism for drilling a borehole. The drilling mechanism includes a drill pipe arranged below a hanging block. Above the base, there is a rotating machine. The output end of the rotating machine is drivingly connected to a rotating rod. The rotating rod is drivingly connected to a rotating column. The rotating column is drivingly connected to a second bevel gear. The second bevel gear is meshingly connected to a first bevel gear. Above the first bevel gear, there is a fixedly connected rotating strip, which is used for cleaning the surface of a coarse filter plate. The rotating rod is drivingly connected to a turntable. On the surface of the turntable, there are eccentrically arranged a first convex block and a second convex block. The turntable is rotatably connected to a wide plate. On the surface of the wide plate, there is a vertically driving belt rotatably connected. The vertically driving belt is slidably connected to a cross bar. The cross bar is fixedly connected to a right-angle bar. On the surface of the cross bar, there is a fixedly connected fixing convex block, which is used for sliding in a chute on the side surface of a right-angle turning block. The cross bar is rotatably connected to a right-angle turning block. On the surface of the cross bar, there is a cleaning strip, which is used for cleaning a fine filter plate.

[0007] The above technical solutions further include:

[0008] The output end of the rotating machine is drivingly connected to a driving belt. The end of the driving belt away from the rotating machine is drivingly connected to a rotating rod. The rotating rod is rotatably connected to an adapter block. The rotating rod is drivingly connected to a perforated belt. The perforated belt is drivingly connected to a rotating column. The rotating column is rotatably connected to the bottom of the base. The rotating column is drivingly connected to a belt under the base. The end of the belt under the base away from the rotating column is drivingly connected to a second bevel gear. The rotating rod is drivingly connected to a connecting belt. The end of the connecting belt away from the rotating rod is drivingly connected to a turntable. On the surface of the wide plate, there is a rotatably connected rotating block.

[0009] A bearing box is fixedly connected above the base. A partition plate is arranged inside the bearing box. A storage tank for circulating mud is arranged inside the bearing box. A wide groove for storing mudstone blocks is arranged inside the bearing box.

[0010] The drilling mechanism includes a support plate arranged above the base. The support plate is rotatably connected with a first roller. The first roller is drivingly connected with a vertical transmission belt. One end of the vertical transmission belt is drivingly connected with the output end of a rotating machine. An auxiliary block for supporting the rotation of a second roller is arranged above the support plate. The auxiliary block above the support plate is rotatably connected with a long coiling roller. The second roller is drivingly connected with a horizontal transmission belt. One end of the horizontal transmission belt away from the second roller is drivingly connected with the first roller.

[0011] A first pump body is fixedly connected above the base. A pipeline for leading to the inside of a spraying pipe is arranged above the first pump body. The spraying pipe is fixedly connected to the upper part of the bearing box. A hose is arranged at one end of the first pump body.

[0012] Tracks for movement are arranged at the bottom of the base. The arrangement of the tracks endows the drilling device with good mobility and terrain adaptability. In the complex working environment of a mine, the tracks have a large contact area with the ground and a small pressure, and can stably travel on soft, muddy or uneven ground, and are not prone to slipping, sinking and other situations, enabling the device to quickly and conveniently move to different drilling areas.

[0013] A fine filter plate is arranged on the side of the bearing box, and the bearing box is fixedly connected with a fine filter box. The combination of the fine filter plate, the bearing box and the fine filter box constructs a multi-stage fine filtering system. The fine filter plate can intercept fine particles in the mud input liquid, prevent them from entering the drill hole and causing wear to the drill pipe and drill bit, effectively extend the service life of the drilling tools, and reduce the equipment maintenance cost; the fixed connection between the bearing box and the fine filter box enables the mud to complete the filtering cycle in a closed and stable space, ensuring the continuity and high efficiency of the filtering process and preventing the mud from overflowing and polluting the environment.

[0014] A square block for supporting the rotation of a second bevel gear is arranged at the bottom of the base. The supporting square block arranged at the bottom of the base provides a stable supporting structure for the second bevel gear. This square block ensures that the second bevel gear maintains an accurate position and a stable operating state during rotation, guaranteeing the reliability of the power transmission system. By stably supporting the second bevel gear, the internal power transmission of the device is made smoother, avoiding problems such as a decrease in transmission efficiency and an increase in noise caused by gear shaking and offset. Furthermore, it ensures that components such as the rotating long strip can operate stably, effectively realizing the cleaning of large mud blocks on the coarse filter plate, preventing the mud blocks from blocking the filtering equipment, and enhancing the working stability and durability of the entire drilling device.

[0015] Multiple groups of rotating blocks are provided on the side of the wide plate. The multiple groups of rotating blocks on the side of the wide plate provide key nodes for the internal mechanical transmission and motion conversion of the device. The rotating blocks can be flexibly matched with other transmission components to achieve force transmission and change of motion direction. During the process of the rotating disk driving related components to perform eccentric circular motion, the multiple groups of rotating blocks assist in realizing the left-right cyclic sliding of components such as the cross bar and the cleaning bar, efficiently cleaning the small particle impurities accumulated on the surface of the fine filter plate, preventing the impurities from affecting the mud input flow rate and filtration effect; at the same time, the setting of the multiple groups of rotating blocks enhances the linkage and flexibility of the internal mechanical structure of the device, enabling each component to work together and improving the overall operation efficiency and reliability of the device.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the present invention, the device rotates the long strip in forward and reverse directions to sweep the large mud blocks above the coarse filter plate to one side treatment tank, effectively avoiding the blockage of the holes on the surface of the coarse filter plate by large mud blocks and rock blocks, ensuring the smoothness of the mud input liquid in the filtration link. Cooperating with the left-right cyclic sliding of the cleaning bar to prevent small particle impurities from accumulating on the surface of the fine filter plate, ensuring the stable operation of the mud circulation system, reducing the shutdown treatment time caused by unsmooth mud circulation, and significantly improving the drilling construction efficiency.

[0018] 2. In the present invention, on the one hand, the large mudstone blocks are centrally collected and processed to avoid the pollution of the land and the surrounding ecological environment by harmful substances such as heavy metals in them. On the other hand, by intercepting the fine particles in the mud input liquid through the fine filter plate, the solid particles entering the drill pipe and drill bit are reduced, the wear degree of the drilling tools is reduced, the service life of the drill pipe and drill bit is prolonged, the equipment replacement and maintenance costs are reduced, and the safety and economy of the drilling operation are ensured.

At the same time, the setting of the multiple groups of rotating blocks 29 enhances the linkage and flexibility of the internal mechanical structure of the device, enabling each component to work together and improving the overall operation efficiency and reliability of the device.

[0039] The working principle of a drilling device for soft and broken surrounding rock in a mine in the present invention is as follows. First, it moves to the area to be drilled by means of the crawlers at the bottom of the base 1. Then, the mud conveying liquid is conveyed into the central hole of the drill pipe below the hanging block 14 by means of the input pump above the base 1. Then, when drilling is carried out using the drill pipe below the hanging block 14, it will drill down a certain distance. Then, the output end of the rotating machine 6 is controlled to retract, so as to prevent the drill bit from continuously drilling down and suffering huge wear. When the drilling depth is relatively deep, the drill pipe below the hanging block 14 will be insufficient in length. At this time, another set of drill pipes will be connected to the drill pipe, and the rotating machine 6 will rotate in the reverse and forward directions. Then, as the drilling starts, the mud input liquid will overflow from the periphery of the drill pipe and enter the reserved pretreatment pool. Then, the first pump body 3 is controlled to suck it, and then it is sprayed above the coarse filter plate 5 through the spraying pipe 4. Then, the mud input liquid filtered by the coarse filter plate 5 enters below the coarse filter plate 5 and then enters the inside of the bearing box 2. Then, the mud input liquid inside the bearing box 2 is input into the central hole of the drill pipe again by the input pump above the base 1 to ensure recycling. As the rotating machine 6 continuously rotates in the reverse and forward directions, the rotating machine 6 will drive the rotating rod 16 to rotate by means of the transmission belt 8. The rotation of the rotating rod 16 drives the rotating column 35 to rotate through the perforated belt 36. The rotation of the rotating column 35 will drive the second bevel gear 33 to rotate by means of the belt under the seat 34. The second bevel gear 33 will engage with the first bevel gear 32 to drive the rotating strip 31 to rotate in the reverse and forward directions, so as to sweep the large mud blocks above the coarse filter plate 5 to the treatment tank on one side, so as to ensure that the large mud blocks and rock blocks do not block the holes on the surface of the coarse filter plate 5.

[0040] Secondly, the large mud and rock blocks are swept to the treatment tank on one side by the rotating strip 31, which can prevent damage to the land, because heavy metals may exist in the large mud and rock blocks. Secondly, the rotation of the rotating rod 16 will drive the rotating disc 21 to rotate by means of the connecting belt 17. The rotation of the rotating disc 21 will drive the first convex block 22 and the second convex block 23 to perform eccentric circular motion. Figure 4 For example, when the rotating disc 21 rotates clockwise, it will use the second convex block 23 to push the right-angle bar 28 to drive the cross bar 27 to move to the left. When the rotating disc 21 continues to rotate, it will use the first convex block 22 to push one right-angle side of the right-angle crank block 24. When one right-angle side of the right-angle crank block 24 is pushed, it will drive the rotation, so that the fixed convex block 26 slides in the chute 25 of the right-angle crank block 24 to realize the rightward sliding of the cross bar 27. When the rotating disc 21 continues to rotate, it will use the second convex block 23 to push the right-angle bar 28 to slide to the left again. Therefore, the cleaning bar 30 realizes left-right cyclic sliding, so as to prevent a large amount of small particle impurities from accumulating on the surface of the fine filter plate 19, thus affecting the subsequent mud input flow rate.

[0041] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
