Description

Technical Field

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

[0002] Ore mining is the technology and science of extracting mineral resources from within the earth's crust and on the earth's surface. Broadly speaking, mining also includes the extraction of coal and petroleum. The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metal ores are important chemical raw materials and building materials. The mining industry is the main way to obtain existing energy sources; During the process of coal mine shaft mining, in order to lift and transport coal, tools, etc. at the bottom of the mine, a wire rope winding and lifting device is often used, and a mining bucket is used to store ores. However, when loading the mining bucket, since the loading materials are mostly mudstone or minerals, the loading quality is often uneven; In the prior art, for example, a rotary adjustment lifting device for a mining bucket used in shaft mining with the Chinese patent publication number CN116654747A mainly monitors the pressures received by the mining bucket in eight directions through eight pressure sensors installed at the bottom of the mining bucket. Subsequently, the third motor operates, driving the adjusting wheel and the second adjusting wheel to rotate through the linkage wheel, transmission gear, etc., so that the adjusting mechanism moves on the cross-set pulling ropes, so that the adjusting mechanism is above the center of gravity of the mining bucket to extend it; However, during this process, the mudstone or minerals in the mining bucket are actually still in an unbalanced state inside the bucket. Once the sensors fail due to harsh environmental factors such as humidity, dust, and electromagnetic interference in the mine shaft, the pressures in each direction cannot be accurately monitored, resulting in difficulty in correctly adjusting the adjusting mechanism. The mining bucket is extremely likely to touch the inner wall of the shaft during the stretching process, which not only affects the stable operation of the equipment, but also may cause serious safety accidents such as damage and tipping over of the mining bucket. At the same time, the cost of the sensors is relatively high, which will also increase the maintenance and operation costs of the equipment; In addition, the humid and dusty environment in the mine shaft makes it easy for miscellaneous dust to adhere to the surface of the steel wire. This not only accelerates the wear of the steel wire, reduces its service life, but also may affect the normal operation of the wire rope winding and lifting device, increasing potential safety hazards; In view of this, there is an urgent need for a rotary adjustment lifting device for a mining bucket used in shaft mining to solve the above problems. Summary of the Invention

[0003] The present invention provides a rotary adjustment lifting device for a mining bucket used in shaft mining, which realizes precise shaking and leveling through an adjusting component and reduces wear through a lubricating component to ensure stable lifting, thereby solving the problems raised in the above background art; To achieve the above object, it includes the main body of the mining hoisting equipment. The main body of the mining hoisting equipment includes a frame body. Two side cavities are formed on both sides of the frame body. A middle rod is fixedly installed in the middle of the frame body. A hoisting mechanism is arranged inside one of the side cavities. One end of the hoisting mechanism away from the side cavity passes through the middle rod and is connected to an adjusting component. The adjusting component can connect the mining bucket body with the hoisting mechanism to realize the lifting and collection of minerals. The adjusting component includes a split pipe. The adjusting component is used to pull and shake the mining bucket body. A lubricating component is arranged inside the bottom end of the split pipe. During the process of pulling the mining bucket body, the lubricating component can realize the lubrication of the pulling end of the adjusting component.

[0004] Preferably, the adjusting component further includes a rope installation block fixedly connected to the side of the parallel rope body away from the side cavity. The rope installation block is movably connected to the top of the split pipe. The split pipe includes a fixed pipe and a clamping disc. A split cavity is opened inside the inner cavity of the fixed pipe. Four extension holes are opened inside the clamping disc.

[0005] As a further improvement of this technical solution, an adjusting cavity is formed inside the fixed pipe. Four split rope winding rollers are rotatably arranged inside the adjusting cavity. The four split rope winding rollers are evenly arranged inside the adjusting cavity. Split rope bodies are wound on the surfaces of the four split rope winding rollers. One ends of the four split rope bodies away from the split rope winding rollers respectively pass through the four extension holes and are connected to the top of the mining bucket body. Four adjusting motors are installed inside the split cavity. The output shafts of the four adjusting motors are respectively connected to the rotating shafts of the four split rope winding rollers.

[0006] This is one of the purposes of the present invention. The adjusting component uses the split rope winding rollers and adjusting motors inside the split pipe to control the multiple winding and unwinding of the split rope bodies, pull and shake the mining bucket body, redistribute the internal minerals, achieve automatic balance, avoid the center of gravity deviation, and reduce the risk of touching the inner wall of the vertical shaft.

[0007] As a further improvement of this technical solution, sealing gasket rings are fixedly installed inside the four extension holes. The four sealing gasket rings are all tubular structures. The four sealing gasket rings are all made of elastic materials.

[0008] Preferably, the lubricating component is located inside the sealing gasket ring. The lubricating component includes a storage cavity opened inside the sealing gasket ring. A plurality of outlet holes are opened on one side of the storage cavity close to the inside of the sealing gasket ring. A packing member for filling lubricating oil is arranged at the bottom of the inner cavity of the storage cavity.

[0009] This is the second object of the present invention. When the lubricating component at the bottom end of the split stock pipe pulls the mining bucket body, the lubricating oil in the sealing gasket ring cavity seeps out through the outlet holes to lubricate the pulling end. The lubricating film reduces the frictional loss of the split stock rope body, reduces the adhesion of miscellaneous dust, prolongs the service life of components, and reduces the maintenance cost.

[0010] As a further improvement of this technical solution, an inner coating film is laid on the surface of the sealing gasket ring, and the inner coating film is in a smooth state.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this mining bucket rotation-adjusting lifting device for shaft mining, the effect of efficiently and stably lifting minerals is achieved: Through the cooperation of the parallel stock rope winding roller, the driving motor, and the middle pipe in the lifting mechanism, the driving motor drives the parallel stock rope winding roller to rotate, and the middle pipe limits the pulling path of the parallel stock rope body. At the same time, the angle support buckle provides support force at the bending part to ensure the stable winding and unwinding of the parallel stock rope body, thereby realizing the stable lifting and lowering of the mining bucket body and efficiently completing the mineral lifting and collection operation.

[0012] 2. In this mining bucket rotation-adjusting lifting device for shaft mining, the effect of automatically balancing the placement of minerals is achieved: The adjusting component controls the winding and unwinding length of the split stock rope body through the split stock rope winding roller and the adjusting motor inside the split stock pipe. By winding and unwinding multiple times to pull and shake the mining bucket body, the minerals stored inside are redistributed during the shaking process to achieve the purpose of balanced placement, effectively reducing the center of gravity deviation caused by uneven mineral filling, ensuring that the mining bucket remains in a balanced state during the final stretching and lifting, reducing its contact with the inner wall of the shaft, and reducing the risk of equipment damage and potential safety hazards.

[0013] 3. In this mining bucket rotation-adjusting lifting device for shaft mining, the effect of reducing the wear and dust adhesion of the split stock rope body is achieved: When the lubricating component inside the bottom end of the split stock pipe pulls the mining bucket body, the lubricating oil in the storage cavity inside the sealing gasket ring seeps out through the outlet holes to lubricate the pulling end of the adjusting component. The lubricating film formed by the lubricating oil can not only significantly reduce the frictional loss of the split stock rope body during the process of pulling the mining bucket body, but also effectively reduce the adhesion of miscellaneous dust on the surface of the split stock rope body, avoiding the aggravation of component wear caused by miscellaneous dust, thereby prolonging the service life of the split stock rope body and related components and reducing the equipment maintenance cost.

[0014] 4. In this mining bucket rotation-adjusting lifting device for shaft mining, the effect of optimizing the structural sealing and protection is achieved: The sealing gasket ring inside the extension hole in the adjusting component is an elastic tubular structure, which can effectively prevent moisture and dust in the damp and dusty underground environment from entering the inside of the split stock pipe, avoiding damage to components such as the adjusting motor and the split stock rope winding roller. At the same time, the limiting pipe guides and limits the split stock rope body, further enhancing the structural stability and improving the sealing and protection performance of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] In mining operations, the mud, stones or minerals in the mining bucket are often in an unbalanced state. The underground environment is humid, dusty and has severe electromagnetic interference. Once the sensors used to monitor the pressure in all directions malfunction, it is easy to cause the mining bucket to easily touch the inner wall of the vertical shaft during the lifting process, which may lead to safety accidents such as equipment damage and tipping over. On the other hand, the humid and dusty environment in the mine will cause miscellaneous dust to adhere to the surface of the pull rope, accelerating wear, shortening the service life, affecting the normal operation of the pull rope winding and lifting device, and bringing potential safety hazards. In view of this, the present invention provides a rotary adjustment lifting device for a mining bucket used in shaft mining. Refer to Figures 1 - 5 As shown in the figure, it includes a mining lifting equipment body 1, which comprises a frame 11. There are two side cavities 12 on both sides of the frame 11, and a middle rod 13 is fixedly installed in the middle. A lifting mechanism 2 is arranged in one of the side cavities 12. One end of the lifting mechanism 2 far from the side cavity 12 passes through the middle rod 13 and is connected to an adjustment assembly 3. The adjustment assembly 3 can connect the mining bucket body 14 and the lifting mechanism 2, so as to realize the lifting and collection of minerals. The adjustment assembly 3 includes a split tube 31, which can pull and shake the mining bucket body 14. A lubrication assembly 6 is arranged inside the bottom end of the split tube 31. When pulling the mining bucket body 14, the lubrication assembly 6 can lubricate the pulling end of the adjustment assembly 3.

[0019] First, the specific structure of the lifting mechanism 2 is disclosed. The lifting mechanism 2 includes a combined pull rope winding roller 21 installed in one of the side cavities 12. A combined pull rope body 22 is wound on the surface of the combined pull 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 combined pull rope body 22.

[0020] Two winding discs 23 are arranged inside the side cavity 12. The combined pull rope winding roller 21 is movably installed between the two winding discs 23. One end of the combined pull rope winding roller 21 is fixedly connected to the output shaft of a driving motor 24. The driving motor 24 is fixedly installed on the surface of the frame 11.

[0021] Angle support buckles 25 are fixedly installed on the surface of the middle rod 13 on the side far from the combined pull rope winding roller 21 and on the surface of the frame 11 close to the combined pull rope winding roller 21. The two angle support buckles 25 are used to provide support force at the bending part of the combined pull rope body 22.

[0022] The improvement lies in: Combining Figure 1 and Figure 2It can be seen that the stranded rope winding roller 21 of the lifting mechanism 2 is installed in one of the side cavities 12, and the stranded rope body 22 is wound around its surface. This is the basic structure for the lifting mechanism 2 to lift the mining bucket. By rotating the stranded rope winding roller 21, the stranded rope body 22 is wound and released. Specifically, two winding discs 23 are arranged in the side cavity 12, and the stranded rope winding roller 21 is movably installed between the two winding discs 23. The winding discs 23 provide a support and rotation space for the stranded rope winding roller 21, ensuring the stability of the winding roller during rotation. One end of the stranded rope winding roller 21 is fixedly connected to the output shaft of the driving motor 24, and the driving motor 24 is fixedly installed on the surface of the frame body 11. The driving motor 24 serves as a power source to provide power for the rotation of the stranded rope winding roller 21. By controlling the forward and reverse rotation of the motor, the winding and release of the stranded rope body 22 are realized, thereby driving the lifting movement of the mining bucket body 14, and driving the mining bucket body 14 to rise or fall; Further, referring to Figure 2 and Figure 3 As shown, a through hole is opened in the middle of the middle rod 13, and a middle pipe 26 is fixedly installed in the through hole. The function of the middle pipe 26 is to limit the pulling path of the stranded rope body 22. During the winding and release of the stranded rope body 22, the middle pipe 26 can ensure that it moves along a fixed path, preventing the rope from shifting, twisting or winding, etc., ensuring the stability and accuracy of the tensile force conduction during the lifting process, and further making the lifting of the mining bucket body 14 more stable and reliable. Angle support buckles 25 are fixedly installed on the surface of the side of the middle rod 13 away from the stranded rope winding roller 21 and on the surface of the frame body 11 close to the stranded rope winding roller 21. Their function is to provide a supporting force at the bending part of the stranded rope body 22. During the winding and release of the stranded rope body 22, a bend will be formed at the part passing through the middle rod 13 and the frame body 11. The angle support buckles 25 can share the stress at the bending part, preventing the rope from breaking or excessive wear due to stress concentration at these parts, enhancing the structural strength and service life of the rope, and at the same time ensuring the normal operation of the lifting mechanism 2.

[0023] Then, the specific structure of the adjusting component 3 is disclosed. The adjusting component 3 further includes a rope installation block 32 fixedly connected to the side of the stranded rope body 22 away from the side cavity 12. The rope installation block 32 is movably connected to the top of the split pipe 31. The split pipe 31 includes a fixed pipe 311 and a clamping disc 312. A split cavity 3110 is opened inside the inner cavity of the fixed pipe 311, and four extension holes 3120 are opened inside the clamping disc 312.

[0024] An adjustment cavity 34 is formed inside the fixed pipe 311. Four split rope winding rollers 36 are rotatably arranged inside the adjustment cavity 34. The four split rope winding rollers 36 are evenly arranged inside the adjustment cavity 34. Split rope bodies 33 are wound around the surfaces of the four split rope winding rollers 36. One ends of the four split rope bodies 33 away from the split rope winding rollers 36 respectively pass through four extension holes 3120 and are connected to the top of the mining bucket body 14. Four adjustment motors 35 are installed inside the sub-cavity 3110. Output shafts of the four adjustment motors 35 are respectively connected to the rotating shafts of the four split rope winding rollers 36.

[0025] The improvement lies in: Refer to Figure 6 and in combination with Figure 7 and Figure 9 As shown, the adjustment assembly 3 and the combined rope body 22 are connected through a rope mounting block 32. The split pipe 31 and the rope mounting block 32 are movably connected. This connection method provides the necessary movement space for the subsequent attitude adjustment of the mining bucket body 14. During the mining operation, when it is necessary to adjust the balance state of the materials in the mining bucket body 14, stretching and retracting operations of different lengths can be performed on the four split rope bodies 33. Among them, the diameters of the combined rope body 22 and the split rope body 33 shown in the drawings are for illustration purposes. The combined rope body 22 and the split rope body 33 are preferably made of steel wire.

[0026] As Figure 4 and Figure 5 shown, the four split rope bodies 33 are respectively connected to different positions at the top of the mining bucket body 14. When their lengths are retracted and released inconsistently, the magnitudes and directions of the pulling forces received by each connection point of the mining bucket body 14 will be different, causing the mining bucket body 14 to shake. At this time, the materials in the bucket will move fully along with the shaking. The materials that may have been piled up or unevenly distributed originally will be redistributed gradually during the continuous shaking, making the distribution of the materials in the mining bucket body 14 more uniform.

[0027] Meanwhile, under the combined action of gravity and the pulling force of the split rope body 33, the split pipe 31 will rotate at the bottom of the rope mounting block 32. Combining Figure 6 , the rotation of the split pipe 31 further changes the pulling direction and strength of the split rope body 33 on the mining bucket body 14, thereby increasing the shaking amplitude and frequency of the mining bucket body 14. This more intense shaking enables the materials 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 materials.

[0028] In the shaft, the staff responsible for loading minerals into the mining bucket body 14 can closely and intuitively observe the balance state of the minerals inside the mining bucket body 14, further ensuring the balance of the mining bucket body 14.

[0029] It should be noted that by adjusting the rotation of the motor 35, the rotation angle and number of turns of the split rope winding roller 36 can be adjusted. The rotation of the split rope winding roller 36 directly affects the retracting and extending length of the split rope body 33, thereby realizing the fine adjustment of the shaking direction and strength of the mining bucket body 14. In this way, according to the actual material distribution situation, the shaking of the mining bucket body 14 can be adjusted targeted to make the materials reach a more ideal balance state. And when the materials in the mining bucket body 14 are redistributed and ready to be lifted, the four split rope bodies 33 need to be adjusted to the same length.

[0030] In addition, when the mining bucket body 14 stores minerals, the inside is not in a loose accumulation state. Therefore, even during the shaking process of the mining bucket body 14, the minerals in the bucket will not easily fall off. This design not only ensures the safety of the materials during transportation, avoids the waste of resources caused by the spilling of minerals, but also eliminates the potential safety hazards caused by the falling of minerals.

[0031] In the rotary adjustment and lifting device for the mining bucket used in shaft mining, the adjustment component 3 stretches and retracts the four split rope bodies 33 by different lengths. However, during the retracting and extending of the split rope body 33 and the shaking of the mining bucket body 14, the split rope body 33 is affected by various forces and is 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 split rope winding rollers 36. On the side of the four support rods 41 far from the inner wall of the adjustment cavity 34, four limiting tubes 4 are fixedly installed. The four split rope bodies 33 respectively slide inside the four limiting tubes 4.

[0032] The improvement lies in: as shown in Figure 7 and Figure 8 , the support rod 41 fixes the limiting tube 4 in the adjustment cavity 34, providing stable support for the limiting tube 4. The limiting tube 4 provides a clear movement path for the split rope body 33, making it can only slide along the inside of the limiting tube 4 during the retracting and extending process. This effectively reduces the deviation of the split rope body 33 from the normal track due to excessive shaking amplitude, ensuring that the split rope body 33 can be retracted and extended in a predetermined manner, improving the accuracy and stability of the adjustment of the mining bucket body 14.

[0033] Sealing gasket rings 5 are fixedly installed inside the four extension holes 3120. The four sealing gasket rings 5 are all tubular structures and are all made of elastic materials.

[0034] The lubricating assembly 6 is located inside the gasket ring 5. The lubricating assembly 6 includes a storage cavity 61 opened inside the 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 gasket ring 5. A packing member 63 for filling lubricating oil is arranged at the bottom of the inner cavity of the storage cavity 61.

[0035] The improvement lies in: Refer to Figure 7 and in combination with Figure 10 As shown, in the rotary adjustment lifting device for a mining bucket in shaft mining, sealing gasket rings 5 are fixedly installed inside four extension holes 3120 on the clamping disc 312 of the split pipe 31. These gasket rings 5 are of tubular structure and are made of elastic material (preferably thick-walled rubber). Due to the humid, dusty and possibly corrosive gas environment inside the shaft, if not protected, external dust, water vapor, corrosive substances, etc. can easily enter the inside of the split pipe 31 through the extension holes 3120. The elastic gasket ring 5 can closely fit the split cable body 33. When the split cable body 33 passes through the extension holes 3120 and moves in and out, the gasket ring 5 will undergo elastic deformation according to the movement of the cable, always maintaining a good sealing state, effectively preventing external dust, water vapor and other impurities from entering the inside of the split pipe 31, thereby protecting key components such as the split cable winding roller 36 and the adjustment motor 35 in the adjustment cavity 34, preventing these components from malfunctioning due to dust accumulation and water vapor erosion, extending the service life of the equipment, and ensuring the stable operation of the adjustment assembly 3; At the same time, a lubricating assembly 6 is arranged inside the gasket ring 5, which includes a storage cavity 61, outlet holes 62 and a packing member 63. The storage cavity 61 is used to store lubricating oil. When the split cable body 33 passes through the gasket ring 5 and moves in and out, the lubricating oil will seep out through a plurality of outlet holes 62 on one side of the storage cavity 61 close to the inside of the gasket ring 5 under the action of extrusion, friction, etc. during the movement of the split cable body 33, and is smeared on the surface of the split cable body 33 and the parts in contact with the gasket ring 5 to form a lubricating layer. This lubrication process can effectively reduce the frictional resistance between the split cable body 33 and the gasket ring 5 during movement, reduce the wear degree of the split cable body 33, avoid problems such as surface breakage and fracture of the cable due to excessive friction, and at the same time reduce the wear of the gasket ring 5 itself, extending the service life of both. The presence of the packing member 63 makes it convenient to fill the storage cavity 61 with lubricating oil after the lubricating oil is consumed, ensuring that the lubricating assembly 6 continues to function, guaranteeing the long-term stable operation of the adjustment assembly 3, and maintaining the effective adjustment of the mining bucket body 14.

[0036] In the environment of shaft mining, although the gasket ring 5 can play a certain role in sealing and protection, during the long-term passing and movement of the split rope body 33, even with the presence of the lubrication component 6, its surface may still have slight wear, scratches or adhere to some impurities due to various factors. Therefore, an inner coating film 7 is laid on the surface of the gasket ring 5, and the inner coating film 7 is in a smooth state.

[0037] The improvement lies in: as Figure 10 , the presence of the inner coating film 7 can further reduce the friction coefficient between the split rope body 33 and the gasket ring 5, making the split rope body 33 move more smoothly during the movement process, reducing energy loss. At the same time, the smooth surface is not easy to adhere to impurities and dust, can better maintain cleanliness, helps to maintain the sealing performance of the gasket ring 5 and extend its service life. Among them, the material of the inner coating film 7 can be selected as polytetrafluoroethylene, which has an extremely low friction coefficient and can well meet the requirement of the smoothness of the inner coating film 7, reducing the friction between the split rope body 33 and the gasket ring 5.

[0038] In summary, by driving the parallel rope winding roller 21 to rotate through the driving motor 24, cooperating with the limit of the parallel rope body 22 by the middle tube 26 and the support force provided by the angle support buckle 25 at the bending part, the stable lifting of the mining bucket body 14 is realized; Secondly, combined with the adjustment motor 35 driving the split rope winding roller 36 to rotate, so that the four split rope bodies 33 are stretched and retracted with different lengths, resulting in the shaking of the mining bucket body 14. At the same time, the split tube 31 rotates at the bottom of the rope installation block 32 under the action of gravity and the pulling force of the split rope body 33, further intensifying the shaking, realizing the redistribution of the materials in the mining bucket body 14; Then, combined with the limitation of the movement path of the split rope body 33 by the limit tube 4, and the tight fit of the gasket ring 5 with the split rope body 33, effectively preventing external impurities from entering the inside of the split tube 31; Finally, through the lubrication component 6 oozing out lubricating oil to form a lubricating layer when the split rope body 33 moves, the inner coating film 7 further reduces the friction and reduces the wear between the split rope body 33 and the gasket ring 5; Ultimately, it is realized that the mining bucket body 14 keeps stable during the lifting process by evenly placing the loaded materials, 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 shaft mining operations.

[0039] Working principle: During use, the driving motor 24 is started to drive the coaxial rope winding roller 21 to rotate, realizing the winding and unwinding of the coaxial rope body 22, thereby driving the mining bucket body 14 to rise or fall. The middle pipe 26 limits the pulling path of the coaxial rope body 22, and the angle support buckle 25 provides a supporting force at the bending position of the coaxial rope body 22 to ensure stable lifting and lowering. When it is necessary to adjust the material balance in the mining bucket body 14, the adjusting motor 35 operates to adjust the rotation angle and number of turns of the split rope winding roller 36, so that the four split rope bodies 33 are stretched and wound with different lengths, resulting in uneven force on the mining bucket body 14 and causing it to shake. The split pipe 31 rotates at the bottom of the rope mounting block 32 under the action of gravity and the pulling force of the split rope body 33, further intensifying the shaking and prompting the materials in the bucket to redistribute. The limiting pipe 4 ensures that the split rope body 33 moves along a predetermined path. The sealing gasket ring 5 closely fits the split rope body 33 to prevent external impurities from entering the split pipe 31. The lubricating component 6 exudes lubricating oil to form a lubricating layer when the split rope body 33 moves, and the inner coating film 7 further reduces friction and component wear. When the materials are evenly distributed and ready to be lifted, the four split rope bodies 33 are adjusted to the same length to achieve stable lifting and transportation of the mining bucket body 14.
