Description

Technical Field

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

[0002] During the construction of underground mines, after the shaft construction reaches the bottom, the horizontal tunnel construction is turned into the horizontal tunnel construction. In order to improve the slag discharge efficiency, it is necessary to temporarily change the helical system. Among the related technologies, the systems used to realize the horizontal tunnel change and helical system slag discharge are generally the following:

[0003] 1. The bucket lifting system during the well sinking process is used to remove the slag, but the bucket has a small volume, the lifting speed is slow, and the slag removal efficiency is low. In addition, the speed of lifting and lowering personnel and materials is also slow;

[0004] 2. The lifting bucket during the well drilling process is temporarily changed to a skip lifting system. However, due to the limitation of the well drilling lifting system, the skip load is limited and the lifting speed cannot be increased. The slag discharge efficiency is increased compared with the bucket system, but it is difficult to increase significantly. In addition, the skip system cannot lower materials and personnel;

[0005] 3. The lifting bucket during the well drilling is temporarily changed into a cage lifting system. The cage system can facilitate the lifting and lowering of personnel and materials, but since the mine car takes a long time to enter and exit the cage, the slag discharge efficiency is low, so it cannot improve the slag discharge efficiency. Summary of the invention

[0006] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0007] To this end, an embodiment of the present invention proposes a shaft re-twisting system, which can ensure the slag discharge capacity and efficiency of the shaft by adding a bucket structure on the basis of the cage lifting system, with small re-twisting workload, short re-twisting period and low cost.

DETAILED DESCRIPTION

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

[0031] like Figure 1 and Figure 2 As shown, a shaft conversion system according to an embodiment of the present invention comprises a shaft body 1, a hoisting unit 2, a cage 3 and a skip 4, wherein the shaft body 1 has a surface wellhead 11, and at least a portion of the hoisting unit 2 is installed in the shaft body 1 and extends along the extension direction of the shaft body 1; the hoisting unit 2 is connected to the cage 3 and can pull the cage 3 to rise and fall along the extension direction of the shaft body 1, the cage 3 has a containing cavity 31, and the skip 4 is installed in the containing cavity 31, and the skip 4 is suitable for loading slag at the horse head gate 5 and unloading the slag from the surface wellhead 11.

[0032] According to the shaft conversion system of the embodiment of the present invention, a cage 3 lifting system is constructed based on the cooperation of the lifting unit 2 and the cage 3 in the shaft body 1. By installing a skip 4 in the cage 3, the system can lift slag with the help of the skip 4, and the cage 3 carries workers and construction materials at the same time. Among them, the method of adding a skip 4 in the cage 3 realizes the local conversion of the system, which can effectively reduce the adverse effects of the low slag discharge efficiency and slag discharge difficulty of the mine car in the cage 3 lifting system on the speed of ore construction. Therefore, compared with the related art, the present invention can ensure the slag discharge capacity and efficiency of the shaft by adding a skip 4 structure on the basis of the cage 3 lifting system, and the conversion workload is small, the conversion period is short and the cost is low.

[0033] Specifically, the shaft body 1 may not be limited to extending in the up and down directions in the figure. The shaft body 1 may include a shaft and a shaft connected to the inner wall surface of the shaft. At least part of the lifting unit 2 may be arranged in the shaft and extend along the extension direction of the shaft. The lifting unit 2 may not be limited to permanent facilities such as a counterweight, a hoist, a drive device, an electric control device, a lifting wire rope, and a balance tail rope. Its specific structure and working principle can adopt the existing technology in the field and are not limited here. The horse head gate 5 is located in the mine and is connected to the shaft body 1.

[0034] It should be noted that the present invention is not only applicable to the direct re-twisting of a vertical shaft, but also applicable to the re-twisting of a vertical shaft that has been equipped with a permanent lifting cage 3 system. Without changing the vertical shaft and the permanent facilities therein, the present invention can make full use of the existing lifting equipment in the vertical shaft, improve the lifting capacity of the vertical shaft during the capital construction period, save capital construction costs, and improve the slag discharge capacity of the vertical shaft, thereby accelerating the speed of mine capital construction and shortening the mine capital construction period so as to enable the mine to be put into production as soon as possible.

[0035] In addition, the horse head gate 5 is the transition section connecting the bottom of the shaft parking lot tunnel and the vertical shaft, that is, the horse head gate 5 is located at the connection between the vertical shaft and the horizontal tunnel. Therefore, the slag from the horizontal tunnel construction can be loaded by the skip 4 at the horse head gate 5.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the skip 4 is pivotally connected to the cage 3, and the skip 4 can be rotated relative to the cage 3 at the surface wellhead 11 in the direction from the center position of the shaft body 1 toward the well wall, that is, flipped in the direction from the accommodating cavity 31 toward the outer peripheral side of the cage 3, so that the skip 4 can unload the slag.

[0037] It can be understood that by pivotally mounting the skip 4 in the accommodating chamber 31 of the cage 3, the skip 4 does not need to be pulled out of the cage 3 or used with the help of a mine car to discharge the slag. The slag can be directly unloaded by simply flipping it relative to the cage 3 at the surface wellhead 11, thereby reducing the auxiliary workload for slag discharge and the intensity of the operation. In addition, the modification structure of the system is simple, the technical requirements are low, the processing, manufacturing and disassembly are convenient, and the cost is low.

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

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the shaft re-twisting system further includes an unloading curved rail 6 , which is installed at the surface wellhead 11 .

[0040] The bucket 4 has a loading position separated from the unloading curved rail 6 and an unloading position abutting the unloading curved rail 6. When the bucket 4 switches between the loading position and the unloading position, the bucket 4 can be movably connected to the unloading curved rail 6, and the tank cage 3 is raised and lowered along the extension direction of the shaft main body 1 and can push the bucket 4 to move along the unloading curved rail 6, so that the bucket 4 rotates relative to the tank cage 3.

[0041] It can be understood that, in the process of lifting the cage 3 by the lifting unit 2, the skip 4 can enter the unloading curved track 6 and move with it when the cage 3 rises to the unloading curved track 6, so that under the guidance of the unloading curved track 6, the skip 4 can rotate around the fixed axis 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 the system.

[0042] Specifically, the bucket 4 is located below the unloading curved track 6 when in the loading position. The bucket 4 can be confined between the cage 3 and the unloading curved track 6 when in the unloading position. The specific length and direction of the unloading curved track 6 can be designed accordingly according to the angle at which the bucket 4 needs to be turned, the walking track of the bucket 4 turning the corresponding angle during the rising process of the cage 3, etc., which will not be elaborated here. The beginning and the end of the unloading curved track 6 are both open ends, so that the bucket 4 can be easily connected to the unloading curved track 6 during the rising process, ensuring that the bucket 4 and the unloading curved track 6 can be movably matched.

[0043] Taking the figure as an example, the unloading curved track 6 can be arranged on the right side of the surface wellhead 11 in the figure, and the skip 4 can move and cooperate with the unloading curved track 6 when it rises to the bottom of the unloading curved track 6 with the cage 3, and during the continued lifting process of the cage 3, it moves along the unloading curved track 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] like Figure 1 and Figure 2As shown, in some embodiments, the vertical shaft conversion system also includes an unloading chute 7, which is installed at the surface wellhead 11 and has a feed end 71 and a discharge end 72. The feed end 71 of the unloading chute 7 is located above the discharge end 72 in the height direction, and the bucket 4 can be connected to the feed end 71 of the unloading chute 7 when in the unloading position.

[0045] It can be understood that the unloading chute 7 can realize smooth unloading of the slag in the bucket 4 and buffer the impact force of the slag during the unloading process of the bucket 4.

[0046] Specifically, the height of the unloading chute 7 relative to the ground surface can be gradually reduced in the direction from the feed end 71 toward the discharge end 72. The unloading chute 7 can be supported above the ground surface by a bracket. The unloading curved track 6 can be installed on the side wall surface of the unloading chute 7 to achieve the layout of the unloading curved track 6 at the surface wellhead 11. The bucket 4 is located above the feed end 71 of the unloading curved track 6 when in the unloading position. 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 unloading chute 7 can directly enter the surface storage type waste rock bin (mining shuttle car), that is, the discharge end 72 of the unloading chute 7 is located above the surface storage type waste rock bin and is connected thereto, wherein the mining shuttle car is loaded with a mining truck or a belt to transport the slag to the slag field. Alternatively, the slag is directly discharged from the discharge end 72 of the unloading chute 7 to the surface to form a slag pile, and then the slag is transferred by a shovel loader to be transported to the slag field for subsequent processing.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the bucket 4 is provided with a roller ear 41, and when the bucket 4 is switched between the loading position and the unloading position, the roller ear 41 can be rollingly connected with the unloading curved track 6.

[0049] It can be understood that the design of the roller tank ear 41 can achieve rolling cooperation between the bucket 4 and the unloading curved track 6, reduce the movement wear between the bucket 4 and the unloading curved track 6, and ensure the smooth movement of the bucket 4 along the unloading curved track 6.

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

[0051] like Figure 1 and Figure 2As shown, in some embodiments, the shaft rewinding system also includes a funnel 81 and a first telescopic cylinder 82, the cylinder body of the first telescopic cylinder 82 is pivotally mounted on the horse head gate 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 horse head gate 5 and can lock the two when the funnel 81 is pivoted to any position relative to the horse head gate 5, and the discharge port of the funnel 81 is suitable for being connected to the skip 4.

[0052] It can be understood that the slag in the horizontal tunnel can be temporarily stored through the funnel 81 at the horse head gate 5, and when the skip 4 descends to the second predetermined position (i.e., the slag loading position) with the cage 3 and needs to be discharged, the first telescopic cylinder 82 pushes the funnel 81 to flip, so that the slag in the funnel 81 falls into the skip 4 from its discharge port under the action of its own weight, and after the slag loading of the skip 4 is completed, the first telescopic cylinder 82 drives the funnel 81 to reset, preparing for the funnel 81 to continue to temporarily store the slag in the horizontal tunnel, thereby improving the mechanization and intelligence of the system, realizing the automated control of slag loading underground and slag unloading above ground, and at the same time being conducive to the organization of personnel and equipment, reducing idle work, and having low work intensity.

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

[0054] It should be noted that the present invention completes a slag discharge operation at the surface above the well. When the staff performs the slag processing operation, the slag can be continuously loaded into the skip 4 underground. Similarly, when the skip 4 performs the slag unloading operation at the surface wellhead 11, the staff can continue the slag temporary storage operation underground, so as to realize the linkage operation above the well and underground, greatly reduce the number of staff, further speed up the progress of infrastructure construction, and shorten the construction period of infrastructure.

[0055] In addition, the slag at the face in the horizontal tunnel can be first loaded into a mining truck by a shovel loader, and then transported to the horse head gate 5 by the mining truck to be temporarily stored in the funnel 81, or when the distance between the face and the horse head gate 5 is short, the slag can also be directly transported to the horse head gate 5 by a shovel loader to be unloaded into the funnel 81.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the shaft conversion system further includes a material level meter 83 , which is installed on the horse head gate 5 and located above the funnel 81 . The material level meter 83 is used to measure the slag material level in the funnel 81 .

[0057] It can be understood that the material level meter 83 can monitor the slag material level in the funnel 81 in real time to ensure that the skip 4 does not spill slag during the lifting process due to overfilling when the funnel 81 unloads slag into the skip 4, thereby improving construction safety.

[0058] It should be noted that when the slag is loaded into the hopper 81, the slag level in the hopper 81 can be monitored by the level meter 83 to control the total amount of slag loaded into the hopper 81, so that the total amount of slag is not greater than the maximum volume of the bucket 4, ensuring that the slag loaded in the bucket 4 will not overflow. In this way, all the slag in the hopper 81 is unloaded into the bucket 4. Alternatively, the initial value of the slag level in the hopper 81 and the height value of the slag level after unloading are monitored by the level meter 83 to control the slag unloading amount in the bucket 4 from the hopper 81, so that the unloading amount is not greater than the maximum volume of the bucket 4, ensuring that the slag loaded in the bucket 4 will not overflow. In this way, part of the slag in the hopper 81 is unloaded into the bucket 4.

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, the funnel 81 is provided with scale lines along the height direction to measure the slag level in the funnel 81, so as to coordinately measure the slag level with the level meter 83 to ensure the detection accuracy of the slag level in the funnel 81, wherein the height direction may be the up and down direction in the figure.

[0060] like Figure 1 and Figure 2 As shown, in some embodiments, the shaft twisting system also includes a movable chute 84 and a second telescopic cylinder 85, the movable chute 84 is pivotally connected to the horse head gate 5 and has an idle position and a working position, the movable chute 84 is separated from the tank cage 3 in the idle position, and the movable chute 84 is connected to the discharge port of the funnel 81 and the bucket 4 in the working position, the cylinder body of the second telescopic cylinder 85 is installed on the horse head gate 5, 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 funnel 81 and can lock the two when the movable chute 84 is pivoted to any position relative to the discharge port of the funnel 81.

[0061] It can be understood that the cooperation between the movable chute 84 and the second telescopic cylinder 85 can help ensure the smooth unloading of slag in the funnel 81 into the skip 4, further improve the automation performance of the system, and buffer the impact force of slag during the unloading process, thereby reducing damage to the skip 4.

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

[0063] like 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 accommodating cavity 31, the bucket 4 is located below the top platform 33, and a material dropping groove 331 is provided at the edge of the top platform 33, and the part of the movable chute 84 adjacent to the cage 3 cooperates with the material dropping groove 331 in the working position.

[0064] It can be understood that a material dropping slot 331 is cut on 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 bucket 4 in the cage 3. Therefore, the degree of modification of the cage 3 in the related technology is small, the workload of modification is small, and the cost of modification is low.

[0065] Specifically, the discharge port of the movable chute 84 may be smaller than the discharge slot 331 to ensure that the portion of the movable chute 84 adjacent to the cage 3 can be smoothly lifted into the discharge slot 331 and positioned above the bucket 4, thereby achieving smooth unloading of the slag in the movable chute 84 into the bucket 4.

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

[0067] like Figures 1 to 3 As shown, in some embodiments, there are two material discharge slots 331 and they are mirror-symmetrical relative to the 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 and right direction in the figure. The length direction of the top platform 33 forms an angle with the extension direction of the shaft body 1. The center of the top platform 33 is coplanar with the reference plane, so that the bucket 4 can realize double-sided slag loading, further improving the applicability of the system, so as to simultaneously meet the slag discharge requirements at the horse head doors 5 on both sides of the cage 3, and reduce the number of times the system layout orientation needs to be adjusted to complete the slag discharge of the horse head doors 5 at different positions.

[0068] like Figure 1 As shown, in some embodiments, the shaft conversion system also 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 on the horse head gate 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 is pivoted to any position relative to the discharge port of the funnel 81, so that the gate 86 and the third telescopic cylinder 87 cooperate to realize the opening or closing of the discharge port of the funnel 81, thereby ensuring that the funnel 81 unloads or temporarily stores slag.

[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 lifting unit 2 lifts the cage 3 to the surface wellhead 11, and the roller ears 41 of the skip 4 enter the unloading curved track 6 during the ascending process and move in the unloading curved track 6. At the same time, the skip 4 rotates around the fixed axis under the guidance of the unloading curved track 6 until it reaches the first predetermined position (i.e., the slag unloading position).
