Description

Technical Field

[0001] The utility model relates to the technical field of underground mine shaft construction systems, in particular to a shaft conversion and hoisting system. Background Art

[0002] During the infrastructure construction of an underground mine, after the shaft construction reaches the bottom, it is transferred to the heading construction. To improve the mucking efficiency, temporary conversion and hoisting are required. In related technologies, the systems for realizing the conversion and hoisting of the heading mainly include the following several types:

[0003] 1. Using the skip hoisting system during shaft sinking for mucking, but the skip has a small volume, a slow hoisting speed, and a low mucking efficiency. In addition, the speed of hoisting and lowering personnel and materials is also slow;

[0004] 2. Temporarily converting the hoisting skip during shaft sinking into a kibble hoisting system. However, limited by the shaft sinking hoisting system, the kibble load is limited, the hoisting speed cannot be increased, the mucking efficiency is increased compared with the skip system, but it is difficult to increase significantly. In addition, the kibble system cannot lower materials and personnel;

[0005] 3. Temporarily converting the hoisting skip during shaft sinking into a cage hoisting system. The cage system can facilitate the hoisting and lowering of personnel and materials. However, since the time for the mine car to enter and exit the cage is relatively long, the mucking efficiency is low, so the mucking efficiency cannot be improved. Content of the Utility Model

Detailed implementation manners

[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0031] As Figure 1 and Figure 2 shown, a shaft conversion and hoisting system according to an embodiment of the present invention includes a shaft main body 1, a hoisting unit 2, a cage 3 and a skip 4. The shaft main body 1 has a surface shaft opening 11. At least a part of the hoisting unit 2 is installed in the shaft main body 1 and extends along the extending direction of the shaft main body 1. The hoisting unit 2 is connected to the cage 3 and can pull the cage 3 to lift and lower along the extending direction of the shaft main body 1. The cage 3 has an accommodating cavity 31, and the skip 4 is installed in the accommodating cavity 31. The skip 4 is adapted to load ore slag at the head gate 5 and unload the ore slag at the surface shaft opening 11.

[0032] According to the shaft conversion and hoisting system of the embodiments of the present utility model, a cage hoisting system is constructed based on the cooperation of the hoisting unit 2 and the cage 3 in the shaft main body 1. By installing a skip 4 in the cage 3, the system can lift slag with the skip 4, and at the same time, the cage 3 transports workers and infrastructure materials. Among them, the local conversion of the system is realized by adding a skip 4 in the cage 3, which can effectively reduce the adverse effects of the low slag discharging efficiency and difficult slag discharging of using mine cars in the cage 3 hoisting system on the ore infrastructure speed. Therefore, compared with the related technologies, the present utility model can, on the basis of the cage 3 hoisting system, ensure the slag discharging capacity and efficiency of the shaft by adding a skip 4 structure, with small conversion workload, short conversion construction period and low cost.

[0033] Specifically, the shaft main body 1 may not be limited to extending in the up and down direction in the figure. The shaft main body 1 may include a shaft tunnel and a shaft barrel connected to the inner wall surface of the shaft tunnel. At least part of the hoisting unit 2 may be arranged in the shaft barrel and extend along the extending direction of the shaft barrel. The hoisting unit 2 may not be limited to including permanent facilities such as a balance weight, a hoist, a driving device, an electric control device, a hoisting steel wire rope, a balance tail rope, etc. Its specific structure and working principle may adopt the existing technologies in the field and will not be limited herein. The shaft head gate 5 is located in the mine and is connected to the shaft main body 1.

[0034] It should be noted that the present utility model is not only applicable to the direct conversion work of the shaft, but also applicable to the conversion work of the shaft already installed with a permanent cage 3 system. Without changing the shaft and its permanent facilities, it can make full use of the existing hoisting equipment of the shaft, improve the hoisting capacity of the shaft during the infrastructure period, save infrastructure costs, improve the slag discharging capacity of the shaft, thereby accelerating the mine infrastructure speed, shortening the mine infrastructure period, and facilitating early production.

[0035] In addition, the shaft head gate 5 is a transition section connecting the roadway of the bottom yard and the shaft barrel, that is, the shaft head gate 5 is located at the connection of the shaft and the level tunnel. Therefore, the slag from the level tunnel construction can be loaded by the skip 4 at the shaft head gate 5.

[0036] As Figure 1 and Figure 2 shown, in some embodiments, the skip 4 may be pivotally connected to the cage 3, and the skip 4 can rotate relative to the cage 3 at the surface shaft opening 11 in a direction from the central position of the shaft main body 1 towards the shaft wall, that is, flip in a direction from the accommodating cavity 31 towards the outer peripheral side of the cage 3, so as to unload the slag of the skip 4.

[0037] It can be understood that by pivotally mounting the skip 4 in the accommodating cavity 31 of the cage 3, the skip 4 does not need to be pulled out of the cage 3 or rely on a mine car or other means to discharge slag. It can directly unload the slag only by flipping relative to the cage 3 at the surface wellhead 11. This reduces the auxiliary workload of slag discharge, lowers the operation intensity, and the modified structure of this system is simple, with low technical requirements, convenient processing, manufacturing, disassembly and assembly, and low cost.

[0038] Specifically, the bottom of the skip 4 can be pivotally connected to the cage 3 through a fixed shaft.

[0039] Such as Figure 1 and Figure 2 As shown in

[0040] In some embodiments, the shaft hoisting system for conversion further includes an unloading curved rail 6, and the unloading curved rail 6 is installed at the surface wellhead 11. The skip 4 has a loading position spaced apart from the unloading curved rail 6 and an unloading position in contact with the unloading curved rail 6. When the skip 4 switches between the loading position and the unloading position, the skip 4 can be movably connected to the unloading curved rail 6. The cage 3 moves up and down along the extending direction of the shaft main body 1 and can push the skip 4 to move along the unloading curved rail 6, so that the skip 4 rotates relative to the cage 3.

[0041] It can be understood that during the process of the lifting unit 2 lifting the cage 3, when the skip 4 rises with the cage 3 to the unloading curved rail 6, it can enter the unloading curved rail 6 and cooperate with its movement. Under the guiding action of the unloading curved rail 6, the skip 4 rotates around the fixed shaft to the first predetermined position (i.e., the slag unloading position). At this time, the cage 3 stops rising, and the skip 4 is in a flipped state to unload the slag, thereby further improving the automatic unloading performance of this system.

[0042] Specifically, when the skip 4 is in the loading position, it is located below the unloading curved rail 6. When the skip 4 is in the unloading position, it can be restricted between the cage 3 and the unloading curved rail 6. The specific length and orientation of the unloading curved rail 6 can be designed accordingly according to the angle that the skip 4 needs to flip, the walking track of the skip 4 flipping at a corresponding angle during the rising process of the skip 4 with the cage 3, etc., and will not be elaborated here. Both the starting end and the ending end of the unloading curved rail 6 are open ends to facilitate the skip 4 to dock with the unloading curved rail 6 during the rising process and ensure the movable cooperation between the skip 4 and the unloading curved rail 6.

[0043] Taking the figure as an example, the unloading curved rail 6 can be arranged on the right side of the surface wellhead 11 in the figure. The skip 4 can move in cooperation with the unloading curved rail 6 when rising with the cage 3 to the bottom of the unloading curved rail 6, and during the continuous lifting process of the cage 3, move along the unloading curved rail 6 until it completes the rightward flipping action relative to the cage 3, and the skip 4 is in the unloading position for unloading.

[0044] Such as Figure 1 and Figure 2As shown, in some embodiments, the shaft conversion and winding system further includes a discharge chute 7. The discharge chute 7 is installed at the surface wellhead 11 and has a feed end 71 and a discharge end 72. The feed end 71 of the discharge chute 7 is above the discharge end 72 in the height direction. When the skip 4 is in the unloading position, it can communicate with the feed end 71 of the discharge chute 7.

[0045] It can be understood that through the discharge chute 7, the smooth unloading of the slag in the skip 4 can be realized, and the impact force of the slag during the unloading process of the skip 4 can be buffered.

[0046] Specifically, the height of the discharge chute 7 relative to the ground surface can gradually decrease along the direction from the feed end 71 towards the discharge end 72. The discharge chute 7 can be supported above the ground surface by a bracket. The unloading curved rail 6 can be installed on the side wall surface of the discharge chute 7 to realize the layout of the unloading curved rail 6 at the surface wellhead 11. When the skip 4 is in the unloading position, it is located above the feed end 71 of the unloading curved rail 6. The height direction can be the up and down direction in the figure.

[0047] It should be noted that the slag discharged from the discharge end 72 of the discharge chute 7 can directly enter the surface storage type gangue bunker (mine shuttle car). That is, the discharge end 72 of the discharge chute 7 is located above and communicates with the surface storage type gangue bunker. Among them, the mine shuttle car loads the mining truck or the belt to transport the slag to the slag yard. Or the slag is directly discharged from the discharge end 72 of the discharge chute 7 to the ground surface to form a slag pile, and then the slag is reloaded by a scraper loader to transport it to the slag yard for subsequent treatment.

[0048] As Figure 1 and Figure 2 As shown, in some embodiments, the skip 4 is provided with roller cage ears 41. When the skip 4 switches between the loading position and the unloading position, the roller cage ears 41 can be in rolling connection with the unloading curved rail 6.

[0049] It can be understood that the design of the roller cage ears 41 can realize the rolling fit between the skip 4 and the unloading curved rail 6, reduce the moving wear between the skip 4 and the unloading curved rail 6, and ensure the smooth walking of the skip 4 along the unloading curved rail 6.

[0050] Specifically, the roller cage ears 41 can be located on the side wall of the skip 4 adjacent to the unloading curved rail 6. The roller cage ears 41 can extend out of the outer side wall of the cage 3 to ensure that the roller cage ears 41 can enter the unloading curved rail 6 to walk during the lifting process of the cage 3. Taking the figure as an example, the roller cage ears 41 are located at the right end of the top of the skip 4.

[0051] As Figure 1 and Figure 2As shown, in some embodiments, the shaft conversion and winding system further includes a funnel 81 and a first telescopic cylinder 82. The cylinder body of the first telescopic cylinder 82 is pivotally installed at the shaft bottom crossheading 5. The piston rod of the first telescopic cylinder 82 is pivotally connected to the funnel 81. The first telescopic cylinder 82 pushes and pulls the funnel 81 to swing relative to the shaft bottom crossheading 5 and can lock the two when the funnel 81 pivots to any position relative to the shaft bottom crossheading 5. The discharge port of the funnel 81 is adapted to communicate with the skip 4.

[0052] It can be understood that the slag in the level roadway can be temporarily stored through the funnel 81 at the shaft bottom crossheading 5. When the skip 4 descends with the cage 3 to the second predetermined position (i.e., the slag loading position) and slag discharge is required, the first telescopic cylinder 82 is made to push the funnel 81 to turn over, so that the slag in the funnel 81 falls into the skip 4 from its discharge port under the action of its own weight. After the slag loading of the skip 4 is completed, the first telescopic cylinder 82 drives the funnel 81 to reset, preparing for the continuous temporary storage of the slag in the level roadway by the funnel 81, improving the mechanization and intelligence level of the system, realizing the automatic control of underground slag loading and surface slag unloading, facilitating the organization of personnel and equipment at the same time, reducing idling, and having a low operation intensity.

[0053] Specifically, the width of the discharge port of the funnel 81 can be smaller than the width of its storage bin (i.e., the inner cavity of the funnel 81) to facilitate slag discharge.

[0054] It should be noted that when the present utility model completes a slag discharge operation at the surface of the well and the staff conducts slag treatment operations, slag loading operations can continue to be carried out underground into the skip 4. Similarly, when the skip 4 conducts slag unloading operations at the surface wellhead 11, the staff can continue to carry out slag temporary storage operations underground to realize the joint operation between the surface and underground, greatly reducing the number of staff, further accelerating the infrastructure construction progress, and shortening the infrastructure construction period.

[0055] In addition, the slag at the heading face in the level roadway can be first loaded into the ore truck by the load-haul-dump machine and then transported to the shaft bottom crossheading 5 by the ore truck for temporary storage in the funnel 81. Or when the distance between the heading face and the shaft bottom crossheading 5 is short, the load-haul-dump machine can also directly transport the slag to the shaft bottom crossheading 5 for unloading into the funnel 81.

[0056] As Figure 1 and Figure 2 shown, in some embodiments, the shaft conversion and winding system further includes a level gauge 83. The level gauge 83 is installed at the shaft bottom crossheading 5 and above the funnel 81. The level gauge 83 is used to measure the slag level in the funnel 81.

[0057] It can be understood that the slag level in the funnel 81 can be monitored in real time by the level gauge 83 to ensure that the skip 4 does not spill slag during the lifting process due to overloading when the funnel 81 discharges slag into the skip 4, improving the construction safety.

[0058] It should be noted that when loading slag into the hopper 81, the slag level in the hopper 81 can be monitored through the level gauge 83 to control the total amount of slag loaded into the hopper 81, so that the total amount of slag does not exceed the maximum volume of the skip 4, ensuring that the slag loaded in the skip 4 does not overflow. In this method, all the slag in the hopper 81 is unloaded into the skip 4. Alternatively, by monitoring the initial value of the slag level in the hopper 81 through the level gauge 83 and the height value of the slag level after slag unloading, the amount of slag unloaded from the hopper 81 into the skip 4 is controlled, so that the amount of unloaded slag does not exceed the maximum volume of the skip 4, ensuring that the slag loaded in the skip 4 does not overflow. In this method, part of the slag in the hopper 81 is unloaded into the skip 4.

[0059] As Figure 1 and Figure 2 shown, in some embodiments, the hopper 81 is provided with scale lines in the height direction to measure the slag level in the hopper 81, so as to cooperate with the level gauge 83 to measure the slag level and ensure the detection accuracy of the slag level in the hopper 81. Among them, the height direction can be the up and down direction in the figure.

[0060] As Figure 1 and Figure 2 shown, in some embodiments, the shaft conversion and hoisting system further includes a movable chute 84 and a second telescopic cylinder 85. The movable chute 84 is pivotally connected to the head gate 5 and has an idle position and a working position. The movable chute 84 is spaced apart from the cage 3 in the idle position, and the movable chute 84 communicates with the discharge port of the hopper 81 and the skip 4 in the working position. The cylinder body of the second telescopic cylinder 85 is installed on the head gate 5, and the piston rod of the second telescopic cylinder 85 is pivotally connected to the movable chute 84. The second telescopic cylinder 85 pushes and pulls the movable chute 84 to swing relative to the discharge port of the hopper 81 and can lock the two when the movable chute 84 pivots relative to the discharge port of the hopper 81 to any position.

[0061] It can be understood that the cooperation of the movable chute 84 and the second telescopic cylinder 85 can assist in ensuring the smooth unloading of the slag in the hopper 81 into the skip 4, further improving the automation performance of the system, and buffering the impact force of the slag during the slag unloading process, reducing the damage to the skip 4.

[0062] Specifically, the feed port of the movable chute 84 can be larger than the discharge port of the hopper 81, and the discharge port of the movable chute 84 can be smaller than the feed port of the skip 4 to ensure the smooth transfer of the slag among the three and avoid the problem of slag spillage.

[0063] As Figures 1 to 3As shown, in some embodiments, the cage 3 includes a connected cage body 32 and a top platform 33. The cage body 32 and the top platform 33 define a receiving cavity 31. The skip 4 is located below the top platform 33. A blanking chute opening 331 is provided at the edge of the top platform 33. The part of the movable chute 84 adjacent to the cage 3 is fitted to the blanking chute opening 331 in the working position.

[0064] It can be understood that the blanking chute opening 331 is cut at the edge of the top platform 33 to facilitate slag loading operations, so that the slag in the movable chute 84 can slide into the skip 4 inside the cage 3. Therefore, the modification degree of the cage 3 in the related art is small, the workload of cage conversion is small, and the cost of cage conversion is low.

[0065] Specifically, the discharge port of the movable chute 84 can be smaller than the blanking chute opening 331 to ensure that the part of the movable chute 84 adjacent to the cage 3 can be smoothly lifted into the blanking chute opening 331 and located above the skip 4, realizing the smooth unloading of the slag in the movable chute 84 into the skip 4.

[0066] It should be noted that the cage 3 may further include a middle platform and a bottom platform, and the specific number of layers of the cage 3 is not limited. When the cage 3 is modified, it is ensured that the skip 4 can be flipped relative to the cage 3 to a first predetermined position, and the movable chute 84 is connected to both the discharge port of the funnel 81 and the skip 4 in the working position.

[0067] As Figures 1 to 3 shown, in some embodiments, there are two blanking chute openings 331 which are mirror-symmetrical with respect to a reference plane. The reference plane is perpendicular to the length direction of the top platform 33, that is, the reference plane is perpendicular to the left-right direction in the figure. The center of the top platform 33 is coplanar with the reference plane, so that the skip 4 can achieve double-sided slag loading, further improving the applicability of the system to simultaneously meet the slag discharge requirements at the two shaft headings 5 on both sides of the cage 3, and reducing the number of adjustments to the layout direction of the system for slag discharge at different shaft headings 5.

[0068] As Figure 1 shown, in some embodiments, the shaft conversion system further includes a gate 86 and a third telescopic cylinder 87. The gate 86 is pivotally connected to the funnel 81 and is used to block the discharge port of the funnel 81. The cylinder body of the third telescopic cylinder 87 is pivotally installed at the shaft heading 5. The piston rod of the third telescopic cylinder 87 is pivotally connected to the gate 86. The third telescopic cylinder 87 pushes and pulls the gate 86 to swing relative to the discharge port of the funnel 81 and can lock the two when the gate 86 pivots to any position relative to the discharge port of the funnel 81, so as to cooperate with the gate 86 and the third telescopic cylinder 87 to open or close the discharge port of the funnel 81, ensuring the unloading or temporary storage of the slag by the funnel 81.

[0069] It should be noted that the first telescopic cylinder 82 , the second telescopic cylinder 85 and the third telescopic cylinder 87 are not limited to being one of a hydraulic cylinder, an oil cylinder, a pneumatic cylinder and an electric cylinder.

[0070] like Figure 1 As shown, in some embodiments, the shaft conversion system also includes a basic frame 88, which is installed on the bottom plate of the horse head gate 5. The cylinder body of the first telescopic cylinder 82, the movable chute 84, the cylinder body of the second telescopic cylinder 85 and the cylinder body of the third telescopic cylinder 87 are all pivotally connected to the basic frame 88, so that the aforementioned components are integrated on the basic frame 88, which is convenient for the rapid disassembly and assembly of the part at the horse head gate 5, and further optimizes the infrastructure efficiency of the system.

[0071] Specifically, the base frame 88 can be fixed on the bottom plate of the horse head door 5 by a long anchor rod.

[0072] Now, combined with the specific structure of the shaft conversion system, its working process is explained, specifically:

[0073] 1) Arrange the lifting unit 2 in the shaft body 1 (or directly use the existing lifting cage 3 system in the shaft body 1), debug the lifting unit 2, open a material drop slot 331 on the top platform 33 of the cage 3, pivotally install the bucket 4 in the accommodating chamber 31 of the cage 3 through a fixed axis, and install a roller ear 41 on the right end of the top of the bucket 4 to complete the transformation of the cage 3. At the same time, install the unloading curved track 6 and the unloading chute 7 on the unloading side of the surface wellhead 11, and install the funnel 81, the material level meter 83, the gate 86 and the basic frame 88 at the horse head gate 5 (the first telescopic cylinder 82, the movable chute 84, the second telescopic cylinder 85 and the third telescopic cylinder 87 are integrated in advance on the basic frame 88), and equip the shovel loader and the mining truck at the face;

[0074] 2) The scraper loads the slag from the face into the mining truck and transports it to the horse head gate 5, or when the distance is short, the scraper directly transports the slag to the horse head gate 5 and unloads it into the funnel 81;

[0075] 3) When the capacity of the skip 4 is met, the lifting unit 2 pulls the cage 3 downward until the skip 4 descends to the second predetermined position (i.e., the slag loading position);

[0076] 4) The hopper 81 is controlled by the first telescopic cylinder 82, and the movable chute 84 is controlled by the second telescopic cylinder 85. The two are lifted to the third predetermined position (i.e., the slag discharge position). The part of the movable chute 84 adjacent to the cage 3 is matched with the material discharge slot 331. Then, the gate 86 is opened by the third telescopic cylinder 87. The slag and stone slide into the bucket 4 under the action of their own weight. After loading is completed, the hopper 81 and the movable chute 84 are restored to their original positions.

[0077] 5) The hoisting unit 2 hoists the cage 3 to the surface wellhead 11. During the upward movement, the roller guide ear 41 of the skip 4 enters the unloading curved rail 6 and travels within the unloading curved rail 6. Meanwhile, under the guiding action of the unloading curved rail 6, the skip 4 rotates around the fixed axis. When it rotates to the first predetermined position (i.e., the slag unloading position), the cage 3 stops rising. The skip 4 unloads the ore slag into the unloading chute 7, and the ore slag is discharged through the unloading chute 7 to the surface storage-type gangue bunker (mine shuttle car). Among them, the mine shuttle car is loaded with a mining truck or a belt to transport the ore slag to the slag yard, completing the primary treatment operation of the ore slag.
