Description

Technical Field

[0001] The invention relates to the technical field of vertical shaft mining, in particular to a mining bucket rotary adjustment and lifting device for vertical shaft mining. Background Art

[0002] Ore mining is the technology and science of extracting mineral resources from the Earth's crust and surface. Mining in a broad sense also includes coal and oil mining. The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials. Mining is the main way to obtain existing energy.

[0003] During vertical coal mining, a wire rope reel is often used to lift and transport coal and tools from the bottom of the mine. Mining buckets are often used to store ore. However, when filling the mining buckets, the quality of the filling is often uneven, as the filling material is mostly mud, rock, or minerals.

[0004] In the prior art, for example, Chinese Patent Publication No. CN116654747A discloses a rotary and adjustable lifting device for a mining bucket used in vertical shaft mining. This device primarily monitors the pressure in eight locations of the mining bucket using eight pressure sensors installed at the bottom of the bucket. Subsequently, a third motor operates, driving an adjustment wheel and a second adjustment wheel via a linkage wheel and a transmission gear, thereby moving the adjustment mechanism on cross-arranged pull ropes, thereby positioning the adjustment mechanism above the center of gravity of the mining bucket and extending it.

[0005] However, during this process, the mud, rock, or minerals in the mining bucket are actually still in an unbalanced state. If the sensor fails due to harsh environmental factors such as humidity, dust, and electromagnetic interference underground, it will not be able to accurately monitor the pressure in all directions, making it difficult to properly adjust the adjustment mechanism. The mining bucket is very likely to touch the inner wall of the shaft during the stretching process, which not only affects the stable operation of the equipment but may also cause serious safety accidents such as damage to the mining bucket and rollover. At the same time, the high cost of sensors will also increase the maintenance and operating costs of the equipment.

[0006] In addition, the humid and dusty environment in the mine makes it easy for dust to adhere to the surface of the steel wire, which not only accelerates the wear of the steel wire and reduces its service life, but also may affect the normal operation of the wire rope winding and lifting device, increasing safety hazards;

[0007] In view of this, there is an urgent need for a rotary adjustment and lifting device for a mining bucket for vertical shaft mining to solve the above problems. Summary of the Invention

[0008] The present invention provides a rotary adjustment and lifting device for a mining bucket for vertical shaft mining, which achieves precise shaking and leveling through an adjustment component, reduces wear of a lubricating component, and ensures stable lifting, thereby solving the problems raised in the above-mentioned background technology.

[0009] To achieve the above-mentioned purpose, a mining lifting device body is provided. The mining lifting device body includes a frame, two side cavities are formed on both sides of the frame, a center rod is fixedly installed in the middle of the frame, a lifting mechanism is provided in one of the side cavities, and an adjustment component is connected to the lifting mechanism at one end of the lifting mechanism away from the side cavity through the center rod. The adjustment component can connect the mining bucket body with the lifting mechanism to achieve the lifting and collection of minerals;

[0010] The adjustment assembly includes a branch pipe, which is used to pull and shake the mining bucket body. A lubrication assembly is provided inside the bottom end of the branch pipe. During the pulling of the mining bucket body, the lubrication assembly can be combined with the lubrication assembly to achieve lubrication of the pulling end of the adjustment assembly.

[0011] Preferably, the adjustment assembly also includes a rope mounting block fixedly connected to the side of the parallel rope body away from the side cavity, the rope mounting block is movably connected to the top of the branch tube, the branch tube includes a fixed tube and a clamping plate, a branch cavity is opened inside the inner cavity of the fixed tube, and four extension holes are opened inside the clamping plate.

[0012] As a further improvement of the present technical solution, an adjusting chamber is formed inside the fixed tube, and four stranded rope winding rollers are rotatably provided inside the adjusting chamber. The four stranded rope winding rollers are evenly arranged inside the adjusting chamber, and the surfaces of the four stranded rope winding rollers are all wrapped with stranded rope bodies. The ends of the four stranded rope bodies away from the stranded rope winding rollers are respectively connected to the top of the mining bucket body through four extension holes, and four adjusting motors are installed inside the chamber, and the output shafts of the four adjusting motors are respectively connected to the rotating shafts of the four stranded rope winding rollers.

[0013] This is one of the purposes of the present invention. The adjustment component uses the strand rope winding roller and the adjustment motor in the strand pipe to control the strand rope body to be retracted and extended multiple times, pull and shake the mining bucket body, redistribute the internal minerals, achieve automatic balance, avoid center of gravity shift, and reduce the risk of touching the inner wall of the shaft.

[0014] As a further improvement of the present technical solution, sealing gaskets are fixedly installed inside the four extension holes, the four sealing gaskets are all tubular structures, and the four sealing gaskets are all made of elastic material.

[0015] Preferably, the lubrication assembly is located inside the sealing gasket ring, and the lubrication assembly includes a storage cavity opened inside the sealing gasket ring, a plurality of outlet holes are opened on the side of the storage cavity close to the inside of the sealing gasket ring, and a filler for filling lubricating oil is provided at the bottom of the inner cavity of the storage cavity.

[0016] This is the second purpose of the present invention. When the lubricating assembly at the bottom of the splitting pipe pulls the mining bucket, lubricating oil in the sealing ring cavity seeps out through the outlet hole to lubricate the pulling end. This lubricating film reduces friction loss in the splitting rope body, reduces dust adhesion, extends component life, and reduces maintenance costs.

[0017] As a further improvement of the present technical solution, the surface of the sealing gasket is covered with an inner coating, and the inner coating is in a smooth state.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This rotary lifting device for a mining bucket used in vertical shaft mining can achieve the effect of efficiently and stably lifting minerals: through the cooperation of the stranded rope winding roller, drive motor and middle tube in the lifting mechanism, the drive motor drives the stranded rope winding roller to rotate, and the middle tube limits the pulling path of the stranded rope body. At the same time, the angle support buckle provides support force at the bending point to ensure the stable retraction and extension of the stranded rope body, thereby realizing the stable lifting and lowering of the mining bucket body and efficiently completing the mineral lifting and collection operation.

[0020] 2. In this mining bucket rotary adjustment and lifting device for vertical shaft mining, the effect of automatic balanced mineral placement is achieved: the adjustment component controls the retraction and extension length of the split rope body through the split rope winding roller and the adjustment motor inside the split pipe, and repeatedly retracts and extends the mining bucket body to pull and shake it, so that the minerals stored inside are redistributed during the shaking process, achieving the purpose of balanced placement, effectively reducing the center of gravity offset caused by uneven mineral filling, ensuring that the mining bucket maintains a balanced state during the final stretching and lifting, reducing its contact with the inner wall of the vertical shaft, and reducing the risk of equipment damage and safety hazards.

[0021] 3. In this mining bucket rotary adjustment and lifting device for vertical shaft mining, the effect of reducing the wear of the stranded rope body and the adhesion of dust is achieved: when the lubricating component inside the bottom end of the stranded pipe pulls the mining bucket body, the lubricating oil stored in the internal cavity of the sealing gasket ring seeps out through the outlet hole to lubricate the pulling end of the adjustment component. The lubricating film formed by the lubricating oil can not only significantly reduce the friction loss of the stranded rope body in the process of pulling the mining bucket body, but also effectively reduce the adhesion of dust to the surface of the stranded rope body, avoid dust from aggravating the wear of components, thereby extending the service life of the stranded rope body and related components, and reducing equipment maintenance costs.

[0022] 4. In this type of rotary adjustment and lifting device for mining buckets used in vertical shaft mining, the effect of optimizing the structural sealing and protection is achieved: the sealing gasket ring inside the extension hole in the adjustment component is an elastic tubular structure, which can effectively prevent moisture and dust in the humid and dusty environment underground from entering the inside of the branch pipe, avoiding damage to the adjustment motor, branch rope winding roller and other components. At the same time, the limit tube guides and limits the branch rope body, further enhancing the structural stability and improving the sealing and protection performance of the equipment.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] During mining operations, the mud, rocks or minerals in the mining bucket are often in an unbalanced state. The underground is humid, dusty and has severe electromagnetic interference. Once the sensor used to monitor the pressure in various directions fails, it is easy for the mining bucket to touch the inner wall of the shaft during the lifting process, which may cause equipment damage, rollover and other safety accidents. On the other hand, the humid and dusty environment of the mine will cause dust to adhere to the surface of the rope, accelerating wear and shortening the service life, affecting the normal operation of the rope winding and lifting device, and posing a safety hazard. In view of this, the present invention provides a rotary lifting device for a mining bucket for vertical shaft mining, see Figure 1-Figure 5 As shown, it includes a mining lifting equipment body 1, which includes a frame 11, two side cavities 12 on both sides of the frame 11, and a middle rod 13 fixedly installed in the middle. A lifting mechanism 2 is provided in one of the side cavities 12, and the end of the lifting mechanism 2 away from the side cavity 12 is connected to the adjustment component 3 through the middle rod 13. The adjustment component 3 can connect the mining bucket body 14 and the lifting mechanism 2 to achieve the lifting and collection of minerals. The adjustment component 3 includes a branch pipe 31, which can pull and shake the mining bucket body 14. A lubrication component 6 is provided inside the bottom end of the branch pipe 31. When the mining bucket body 14 is pulled, the lubrication component 6 can lubricate the pulling end of the adjustment component 3.

[0044] First, the specific structure of the lifting mechanism 2 is disclosed. The lifting mechanism 2 includes a parallel rope winding roller 21 installed in one of the side cavities 12. The parallel rope body 22 is wound around the surface of the parallel rope winding roller 21. A through hole is opened in the middle of the middle rod 13, and a middle tube 26 is fixedly installed inside the through hole. The middle tube 26 can limit the pulling path of the parallel rope body 22.

[0045] Two winding drums 23 are provided inside the side cavity 12, and the stranded rope winding roller 21 is movably installed between the two winding drums 23. One end of the stranded rope winding roller 21 is fixedly connected to the output shaft of the drive motor 24, and the drive motor 24 is fixedly installed on the surface of the frame 11.

[0046] Angle support buckles 25 are fixedly installed on the side surface of the middle rod 13 away from the parallel rope winding roller 21 and the side surface of the frame 11 close to the parallel rope winding roller 21. The two angle support buckles 25 are used to provide support force for the parallel rope body 22 at the bending point.

[0047] The improvement lies in: combining Figure 1 and Figure 2 The rope reel 21 is mounted on the upper and lower parts of the lifting mechanism 2, and the rope reel 21 is mounted on the upper and lower parts of the lifting mechanism 2. The rope reel 21 is mounted on the upper and lower parts of the lifting mechanism 2, and the rope reel 21 is mounted on the upper and lower parts of the lifting mechanism 2. The rope reel 21 is mounted on the upper and lower parts of the lifting mechanism 2, and the rope reel 21 is mounted on the upper and lower parts of the lifting mechanism 2.

[0048] For further information, see Figure 2 and Figure 3 As shown, a through hole is opened in the middle of the middle rod 13, and a middle tube 26 is fixedly installed in the through hole. The function of the middle tube 26 is to limit the pulling path of the parallel rope body 22. During the retraction and extension of the parallel rope body 22, the middle tube 26 can ensure that it moves along a fixed path, preventing the rope from being offset, twisted or entangled, etc., thereby ensuring the stability and accuracy of the tension transmission during the lifting process, thereby making the lifting and lowering of the mining bucket body 14 more stable and reliable. The side surface of the middle rod 13 away from the parallel rope winding roller 21 and the side surface of the frame 11 close to the parallel rope winding roller 21 are both fixedly installed with angle support buckles 25. Their function is to provide support force for the parallel rope body 22 at the bending point. During the retraction and extension of the parallel rope body 22, a bend will be formed at the position passing through the middle rod 13 and the frame 11. The angle support buckle 25 can share the stress at the bending point, preventing the rope from breaking or excessive wear due to stress concentration at these positions, thereby enhancing the structural strength and service life of the rope, and also ensuring the normal operation of the lifting mechanism 2.

[0049] Then the specific structure of the adjustment component 3 is disclosed. The adjustment component 3 also includes a rope mounting block 32 fixedly connected to the side of the parallel rope body 22 away from the side cavity 12. The rope mounting block 32 is movably connected to the top of the branch tube 31. The branch tube 31 includes a fixed tube 311 and a clamping disk 312. A branch cavity 3110 is opened inside the inner cavity of the fixed tube 311, and four extension holes 3120 are opened inside the clamping disk 312.

[0050] An adjusting chamber 34 is formed inside the fixed tube 311. Four split rope winding rollers 36 are rotatably provided inside the adjusting chamber 34. The four split rope winding rollers 36 are evenly arranged inside the adjusting chamber 34. The surfaces of the four split rope winding rollers 36 are all wrapped with split rope bodies 33. The ends of the four split rope bodies 33 away from the split rope winding rollers 36 pass through four extension holes 3120 and are connected to the top of the mining bucket body 14 respectively. Four adjusting motors 35 are installed inside the sub-chamber 3110. The output shafts of the four adjusting motors 35 are respectively connected to the rotating shafts of the four split rope winding rollers 36.

[0051] Improvements include: Figure 6 and combined Figure 7 and Figure 9 As shown, the adjustment component 3 is connected to the parallel rope body 22 through the rope mounting block 32, and the branch pipe 31 and the rope mounting block 32 are connected in a movable manner. This connection method provides necessary space for subsequent adjustment of the posture of the mining bucket body 14. During mining operations, when it is necessary to adjust the balance state of the material in the mining bucket body 14, the four branch rope bodies 33 can be stretched and retracted to different lengths. Among them, the diameters of the parallel rope body 22 and the branch rope body 33 shown in the accompanying drawings are for reference only. The parallel rope body 22 and the branch rope body 33 are preferably made of steel wire.

[0052] like Figure 4 and Figure 5 As shown, the four stranded pull rope bodies 33 are respectively connected to different positions on the top of the mining bucket body 14. When their lengths are not retracted or extended consistently, the pulling forces on the various connection points of the mining bucket body 14 will be different in magnitude and direction, causing the mining bucket body 14 to shake. At this time, the material in the bucket will move fully with the shaking. The material that may have been accumulated or unevenly distributed will gradually be redistributed during the continuous shaking, making the distribution of the material in the mining bucket body 14 more even.

[0053] At the same time, the branch pipe 31 rotates at the bottom of the rope mounting block 32 under the combined action of gravity and the pulling force of the branch rope body 33. Figure 6The rotation of the branch pipe 31 further changes the pulling direction and strength of the branch rope body 33 on the mining bucket body 14, thereby intensifying the shaking amplitude and frequency of the mining bucket body 14. This more violent shaking can allow the material to have more sufficient movement space and time in the bucket, further improving the effect of material redistribution and better improving the balance state of the material.

[0054] In the shaft, the staff responsible for loading the minerals into the mining bucket body 14 can closely and intuitively observe the balance state of the minerals inside the mining bucket body 14 , thereby further ensuring the balance of the mining bucket body 14 .

[0055] It should be noted that by adjusting the rotation of the motor 35, the rotation angle and number of turns of the stranded rope winding roller 36 can be adjusted, and the rotation of the stranded rope winding roller 36 will directly affect the retraction and extension length of the stranded rope body 33, thereby achieving fine adjustment of the shaking direction and strength of the mining bucket body 14. In this way, the shaking of the mining bucket body 14 can be adjusted in a targeted manner according to the actual material distribution, so that the material can reach a more ideal balance state. Moreover, when the material in the mining bucket body 14 is redistributed and ready to be lifted, the four stranded rope bodies 33 need to be adjusted to the same length.

[0056] Furthermore, the minerals in the mining bucket body 14 are not stored in a loose, stacked state. Therefore, even when the mining bucket body 14 is shaken, the minerals inside the bucket will not easily fall out. This design not only ensures the safety of materials during transportation, avoids the waste of resources caused by mineral spillage, but also eliminates the potential safety hazards caused by mineral spillage.

[0057] In the mining bucket rotary adjustment and lifting device for vertical shaft mining, the adjustment component 3 stretches and retracts the four stranded rope bodies 33 to different lengths. However, in the process of retracting and extending the stranded rope bodies 33 and shaking of the mining bucket body 14, the stranded rope bodies 33 will be affected by various forces, and are prone to problems such as large shaking amplitude, mutual entanglement, and deviation from the predetermined track. Therefore, four support rods 41 are fixedly installed inside the adjustment cavity 34. The four support rods 41 are respectively located at the bottom of the four stranded rope winding rollers 36. The four support rods 41 are fixedly installed with limit tubes 4 on the side away from the inner wall of the adjustment cavity 34, and the four stranded rope bodies 33 slide inside the four limit tubes 4 respectively.

[0058] The improvement lies in: combining Figure 7 and Figure 8As shown, the support rod 41 fixes the limiting tube 4 in the adjustment cavity 34, providing stable support for the limiting tube 4, and the limiting tube 4 provides a clear movement path for the stranded pull rope body 33, so that it can only slide along the inside of the limiting tube 4 during the retraction and extension process. This effectively reduces the deviation of the stranded pull rope body 33 from the normal track due to excessive shaking, ensures that the stranded pull rope body 33 can be retracted and extended in a predetermined manner, and improves the accuracy and stability of the adjustment of the mining bucket body 14.

[0059] Sealing rings 5 ​​are fixedly installed inside the four extension holes 3120. The four sealing rings 5 ​​are all tubular structures and are made of elastic material.

[0060] The lubrication assembly 6 is located inside the sealing gasket ring 5. The lubrication assembly 6 includes a storage cavity 61 opened inside the sealing gasket ring 5. A plurality of outlet holes 62 are opened on one side of the storage cavity 61 close to the inside of the sealing gasket ring 5. A filler 63 for filling lubricating oil is provided at the bottom of the inner cavity of the storage cavity 61.

[0061] Improvements include: Figure 7 and combined Figure 10 As shown, in the rotary adjustment and lifting device for the mining bucket for vertical shaft mining, sealing gaskets 5 are fixedly installed inside the four extension holes 3120 on the clamping plate 312 of the branch pipe 31. These sealing gaskets 5 are tubular in structure and made of elastic material (preferably thick-walled rubber). Since the internal environment of the vertical shaft is humid and dusty, and there may also be complex factors such as corrosive gases, if they are not protected, external dust, water vapor, corrosive substances, etc. can easily enter the interior of the branch pipe 31 through the extension holes 3120. The sealing gaskets 5 made of elastic material can fit tightly against the branch rope body 33. When the branch rope body 33 passes through the extension holes 3120 and performs a retracting and extending movement, the sealing gaskets 5 will elastically deform according to the movement of the rope, always maintaining a good sealing state, effectively preventing external dust, water vapor and other impurities from entering the interior of the branch pipe 31, thereby protecting key components such as the branch rope winding roller 36 and the adjustment motor 35 in the adjustment chamber 34, preventing these components from malfunctioning due to dust accumulation and water vapor erosion, thereby extending the service life of the equipment and ensuring the stable operation of the adjustment component 3.

[0062] At the same time, a lubrication assembly 6 is provided within the sealing gasket 5, comprising a storage cavity 61, an outlet hole 62, and a filler 63. The storage cavity 61 is used to store lubricating oil. When the stranded rope body 33 passes through the sealing gasket 5 for retraction and extension, the lubricating oil, due to the squeezing and friction of the stranded rope body 33, seeps out through the multiple outlet holes 62 on the inner side of the storage cavity 61 near the sealing gasket 5, and is coated on the surface of the stranded rope body 33 and the contact area with the sealing gasket 5, forming a lubricating layer. This lubrication process effectively reduces the frictional resistance between the stranded rope body 33 and the sealing gasket 5 during movement, reduces the degree of wear on the stranded rope body 33, and avoids problems such as damage or breakage on the rope surface caused by excessive friction. It also reduces wear on the sealing gasket 5 itself, extending the service life of both. The presence of the filler 63 allows for convenient refilling of the storage cavity 61 after the lubricating oil is consumed, ensuring the continued function of the lubricating assembly 6, the long-term stable operation of the adjustment assembly 3, and the effective adjustment of the mining bucket body 14.

[0063] In the environment of vertical shaft mining, although the sealing gasket ring 5 can play a certain sealing and protective role, during the long-term passage and movement of the split rope body 33, even with the presence of the lubricating component 6, its surface may still produce slight wear, scratches or adhesion of some impurities due to various factors. Therefore, the surface of the sealing gasket ring 5 is covered with an inner coating 7, and the inner coating 7 is in a smooth state.

[0064] The improvements are: Figure 10 The presence of the inner coating 7 can further reduce the friction coefficient between the stranded rope body 33 and the sealing gasket ring 5, making the stranded rope body 33 smoother during movement and reducing energy loss. At the same time, the smooth surface is not easy to adhere to impurities and dust, and can be better kept clean, which helps to maintain the sealing performance of the sealing gasket ring 5 and extend its service life. Among them, the material of the inner coating 7 can be polytetrafluoroethylene. Polytetrafluoroethylene has an extremely low friction coefficient and can well meet the smooth requirements of the inner coating 7, reducing the friction between the stranded rope body 33 and the sealing gasket ring 5.

[0065] In summary, the driving motor 24 drives the parallel rope winding roller 21 to rotate, and the middle tube 26 limits the parallel rope body 22 and the angle support buckle 25 provides support at the bend, thereby achieving stable lifting of the mining bucket body 14;

[0066] Secondly, the regulating motor 35 drives the stranded rope around the roller 36 to rotate, causing the four stranded rope bodies 33 to stretch and retract to different lengths, causing the mining bucket body 14 to shake. At the same time, the stranded pipe 31 rotates at the bottom of the rope mounting block 32 under the action of gravity and the pulling force of the stranded rope bodies 33, further aggravating the shaking and achieving redistribution of the material in the mining bucket body 14.

[0067] Then, the limiting tube 4 limits the movement path of the split rope body 33, and the sealing ring 5 fits tightly against the split rope body 33, effectively preventing foreign matter from entering the split tube 31;

[0068] Finally, the lubricating component 6 releases lubricating oil to form a lubricating layer when the stranded rope body 33 moves, and the inner coating 7 further reduces friction and reduces wear between the stranded rope body 33 and the sealing gasket 5;

[0069] Finally, the mining bucket body 14 is stabilized during the lifting process by balancing the carried materials, thereby ensuring the safety of material transportation, reducing the wear of equipment components, extending the service life of the equipment, and ensuring the smooth progress of the vertical shaft mining operation.

[0070] Working principle:

[0071] During use, the drive motor 24 is activated, driving the stranded rope reel 21 to rotate, achieving the retraction and extension of the stranded rope body 22, thereby driving the mining bucket body 14 to rise or fall. The middle tube 26 limits the pulling path of the stranded rope body 22, and the angle support buckle 25 provides support at the bend of the stranded rope body 22 to ensure stable lifting. When it is necessary to adjust the material balance in the mining bucket body 14, the adjustment motor 35 is operated to adjust the rotation angle and number of turns of the stranded rope winding roller 36, so that the four stranded rope bodies 33 are stretched and retracted to different lengths, causing the mining bucket body 14 to be unevenly stressed and shaken. The stranded pipe 31 rotates at the bottom of the rope mounting block 32 under the action of gravity and the pulling force of the stranded rope body 33, further exacerbating the shaking and prompting the redistribution of the material in the bucket. The stopper tube 4 ensures that the pull rope body 33 follows the predetermined path. The sealing ring 5 tightly fits the pull rope body 33, preventing foreign matter from entering the pull rope tube 31. The lubricating assembly 6 releases lubricating oil as the pull rope body 33 moves, forming a lubricating layer. The inner coating 7 further reduces friction and component wear. Once the material is evenly distributed and ready for lifting, the four pull rope bodies 33 are adjusted to the same length, ensuring smooth lifting and transport of the mining bucket body 14.
