Description

Technical Field

[0001] The utility model relates to the technical field of mine unloading, in particular to a bin lining device and a mine unloading station. Background Art

[0002] The unloading station is a key link in the main hoisting and transportation system, and its bin wall is generally protected by a manganese steel plate lining. The manganese steel plate lining is generally fixed on the bin wall by casting or bolts. However, when unloading ore, the manganese steel plate lining will be continuously impacted and worn by the ore, making the manganese steel plate lining easy to fall off and enter the crusher, resulting in serious safety accidents. In addition, it is not easy to find that the manganese steel plate lining has fallen off, and continuous unloading of ore is likely to wash the bin wall deeper, sometimes even more than 1 meter, so the safety risk is extremely high.

[0003] In the related art, in order to reduce the damage to the manganese steel plate lining during ore unloading and ensure its service life, it is necessary to regularly stop the equipment for maintenance of the manganese steel plate lining. This not only takes a long time to repair and affects production efficiency, but also seriously lacks safety guarantee for maintenance personnel when they enter the chute to deal with the manganese steel plate lining. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related art to a certain extent.

[0005] To this end, an embodiment of one aspect of the utility model provides a bin lining device, which can effectively absorb the impact force during ore unloading to ensure the service life of the lining device and reduce the number of repairs.

[0006] An embodiment of another aspect of the utility model provides a mine unloading station.

[0007] According to an embodiment of the utility model, a bin lining device includes a first plate, a second plate and an elastic member.

[0008] Wherein, the first plate and the second plate are arranged and connected along a first direction. The first plate is adapted to press against the inner wall of the bin. The second plate is adapted to receive the unloaded ore and has a first position and a second position. The second plate can switch relative to the first plate along the first direction from the first position to the second position. The distance between the second plate and the first plate when the second plate is in the first position is greater than the distance between the second plate and the first plate when the second plate is in the second position.

[0009] Wherein, the elastic member is clamped between the first plate and the second plate and can press the second plate towards the first position.

[0010] According to the bin lining device of the embodiment of the present utility model, the first plate, the second plate and the elastic member cooperate to form a lining structure for the bin. When unloading ore into the bin, the ore contacts the second plate, so that the second plate is pushed from the first position to the second position under the impact of the ore, and the impact force of the ore is transmitted to the elastic member connected to the second plate. Through the energy absorption effect of the second plate and the elastic member, the impact kinetic energy is converted into elastic potential energy. Part of the potential energy can be conducted to the first plate, and the first plate then transmits it to the original rock of the inner wall of the bin in contact with it, so that the impact force is transmitted out. The other part of the potential energy acts on the second plate in the opposite direction, and the second plate transmits this potential energy to the ore in contact with it, so as to form a part of the ore barrier with reverse impact force in front of the second plate. When this part of the ore contacts the subsequent ore unloaded from the ore car, it can bear a certain impact, thus effectively protecting the lining device and prolonging the service life of the lining device. At the same time, the ore with reverse impact force collides with the subsequent ore unloaded from the ore car, and the ore is broken under the action of the impact force between the two, ensuring the uniform distribution of the ore in the bin. Therefore, compared with the related art, the present utility model can effectively absorb the impact during ore unloading to ensure the service life of the lining device and reduce the number of maintenance times.

[0011] In some embodiments, the second plate has a first wall surface and a second wall surface opposite to each other in the first direction. The first wall surface of the second plate is closer to the first plate than the second wall surface, and the second wall surface of the second plate protrudes outward in a direction away from the first wall surface.

[0012] In some embodiments, the second plate includes a connected installation part and an intermediate part. The installation part is located on the outer peripheral side of the intermediate part and is connected to the first plate, and the intermediate part protrudes from the installation part in the first direction.

[0013] In some embodiments, on the projection plane perpendicular to the first direction, the outer contour of the projection of the second plate is located inside the outer contour of the projection of the first plate.

[0014] In some embodiments, the bin lining device further includes a monitoring member, which is installed between the first plate and the second plate, and the monitoring member is used to monitor at least one parameter information of the deformation amount and fatigue strength of the elastic member.

[0015] In some embodiments, there are multiple elastic members arranged in an array between the first plate and the second plate, and there are multiple monitoring members corresponding to the elastic members one by one.

[0016] In some embodiments, the bin lining device further includes a warning device, which is installed between the first plate and the second plate, and the warning device is adapted to give a warning prompt according to the monitoring information of the monitoring member.

[0017] In some embodiments, the first plate is a wear-resistant steel plate.

[0018] In some embodiments, the second plate is one of a flexible steel plate and a flexible steel wire mesh plate.

[0019] In some embodiments, the elastic member is a spring.

[0020] According to an embodiment of the present invention, a mine unloading station includes a bunker and a lining device. The lining device is the lining device described in any of the above embodiments. The lining device is connected to the inner wall of the bunker, and the wall surface of the first plate facing away from the second plate in the lining device presses against the inner wall of the bunker.

[0021] According to the mine unloading station of the embodiment of the present invention, the lining of the bunker is designed to adopt a structure formed by the cooperation of the first plate, the second plate and the elastic member, realizing the integration of the lining device, ensuring good protection of the inner wall of the bunker, reducing the risk of ore unloading.

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

[0031] As Figure 1 shown, a kind of ore bin lining device according to an embodiment of the present utility model includes a first plate 1, a second plate 2 and an elastic member 3.

[0032] Among them, the first plate 1 and the second plate 2 are arranged and connected along a first direction. The first plate 1 is adapted to press against the inner wall of the ore bin 5. The second plate 2 is adapted to receive the unloaded ore and has a first position and a second position. The second plate 2 can switch relative to the first plate 1 along the first direction from the first position to the second position. The distance between the second plate 2 and the first plate 1 when the second plate 2 is in the first position is greater than the distance between the second plate 2 and the first plate 1 when the second plate 2 is in the second position.

[0033] Among them, the elastic member 3 is clamped between the first plate 1 and the second plate 2 and can press the second plate 2 towards the first position.

[0034] According to the bin lining device of the embodiment of the present utility model, the first plate 1, the second plate 2 and the elastic member 3 cooperate to form a lining structure for the bin 5. When unloading ore into the bin 5, the ore contacts the second plate 2, so that the second plate 2 is pushed from the first position to the second position under the impact of the ore, and the impact force of the ore is transmitted to the elastic member 3 connected to the second plate 2. Through the energy absorption effect of the second plate 2 and the elastic member 3, the impact kinetic energy is converted into elastic potential energy. Part of the potential energy can be conducted to the first plate 1, and the first plate 1 then transmits it to the original rock on the inner wall of the bin 5 in contact with it, so that the impact force is transmitted out, while the other part of the potential energy acts on the second plate 2 in the reverse direction. The second plate 2 transmits this potential energy to the ore in contact with it, so as to form a part of the ore barrier with reverse impact force in front of the second plate 2. When this part of the ore contacts the subsequent ore unloaded from the ore car, it can bear a certain impact, thus effectively protecting the lining device and prolonging the service life of the lining device. At the same time, the ore with reverse impact force impacts the subsequent ore unloaded from the ore car, and the ore is broken under the action of the impact force of the two, ensuring the uniform distribution of the ore in the bin 5. Therefore, compared with the related technology, the present utility model can effectively absorb the impact during ore unloading to ensure the service life of the lining device and reduce the number of maintenance times.

[0035] Specifically, the first direction can be the thickness direction of the first plate 1, that is, the left-right direction in the figure. The first plate 1, the elastic member 3 and the second plate 2 are arranged and connected in sequence from left to right. The left side wall of the first plate 1 can be connected to the inner wall of the bin 5 to realize the installation of the lining device on the inner wall of the bin 5. The first plate 1 can be a wear-resistant steel plate, so that the first plate 1 is in rigid contact with the original rock to ensure the support performance for the original rock, and the wear resistance of the first plate 1 itself can ensure the service life of the first plate 1 to a certain extent. The second plate 2 can be a flexible steel plate or a flexible steel wire mesh plate. Preferably, the second plate 2 is an elastic steel plate or an elastic steel wire mesh, so that the second plate 2 has elastic properties to cooperate with the elastic member 3 to form a good energy absorption structure and ensure the effect of converting the impact kinetic energy into elastic potential energy. The elastic member 3 is not limited to a spring.

[0036] As Figure 1 shown, in some embodiments, the second plate 2 has a first wall surface 21 and a second wall surface 22 opposite to each other in the first direction. The first wall surface 21 of the second plate 2 is closer to the first plate 1 than the second wall surface 22, and the second wall surface 22 of the second plate 2 protrudes outward in the direction away from the first wall surface 21.

[0037] It can be understood that designing the wall surface of the second plate 2 in contact with the ore as a convex structure can enable most of the unloaded ore to be received by the second wall surface 22 of the second plate 2, and under the action of the second wall surface 22, it falls from the middle area of the bin 5, reducing the contact probability between the ore and the inner wall of the bin 5 and effectively avoiding the problem of scouring the inner wall of the bin 5 during the ore unloading process.

[0038] Specifically, the first wall surface 21 corresponds to the left side wall of the second plate 2, and the second wall surface 22 corresponds to the right side wall of the second plate 2. The first wall surface 21 may be fixedly connected to the elastic member 3 by welding, not limited thereto. In order to further simplify the structure of the second plate 2, improve processing efficiency, and reduce costs, the second plate 2 may be designed as a convex structure protruding from the first plate 1 to the inner cavity of the ore bin 5, that is, the first wall surface 21 of the second plate 2 protrudes outward in a direction away from the first plate 1, and its convex direction is consistent with the convex direction of the second wall surface 22 of the second plate 2, that is, the first wall surface 21 of the second plate 2 is parallel to the second wall surface 22. Preferably, the second plate 2 is an arc-shaped elastic steel plate convex to the right.

[0039] like Figure 2 As shown, in some embodiments, the second plate 2 includes a connected mounting portion 23 and a middle portion 24, the mounting portion 23 is located on the outer peripheral side of the middle portion 24 and is connected to the first plate 1, and the middle portion 24 protrudes from the mounting portion 23 in a first direction, that is, along the first direction, the distance between the middle portion 24 and the first plate 1 at the first position is greater than the distance between the mounting portion 23 and the first plate 1.

[0040] It can be understood that the mounting portion 23 can realize convenient connection between the second plate 2 and the first plate 1, and the middle portion 24 can receive most of the unloaded ores. Therefore, the second plate 2 structure formed by the mounting portion 23 and the middle portion 24 is more convenient for quick assembly between the first plate 1 and the second plate 2 compared to the entire second plate 2 which is convex, and also allows the ore to fall from the middle area of the ore bin 5.

[0041] Specifically, the mounting portion 23 and the middle portion 24 can be integrally formed. The mounting portion 23 is detachably connected to the first plate 1, so that during later maintenance, the lining device can be repaired by only replacing the second plate 2 and the elastic member 3 thereon, thereby ensuring the service life of the lining device and saving costs.

[0042] like Figure 2 As shown, in some embodiments, on the projection plane perpendicular to the first direction, the outer contour of the projection of the second plate 2 is located inside the outer contour of the projection of the first plate 1 , that is, the outer periphery of the second plate 2 is located inside the outer periphery of the first plate 1 .

[0043] It can be understood that the outer periphery of the second plate 2 is designed to be located on the inner side of the outer periphery of the first plate 1, so that sufficient installation space can be reserved for the disassembly, assembly and replacement of the second plate 2 during later maintenance, thereby facilitating maintenance operations. At the same time, when the second plate 2 is deformed by the impact of the ore, any two adjacent second plates 2 will not interfere with each other, thereby ensuring that the lining device provides good protection for the ore bin 5. In addition, the processing accuracy requirements for the first plate 1 and the second plate 2 are reduced, thereby improving production and installation efficiency.

[0044] As Figure 1 and Figure 2 shown, in some embodiments, the bin lining device further includes a monitoring member 4. The monitoring member 4 is installed between the first plate 1 and the second plate 2, and is configured to monitor at least one parameter information of the deformation amount and fatigue strength of the elastic member 3.

[0045] It can be understood that the deformation condition or fatigue strength of the elastic member 3 can be monitored by the monitoring member 4, so that when the elastic member 3 can no longer absorb the impact kinetic energy, the lining device can be maintained in time according to the feedback information of the monitoring member 4, thereby realizing the self - protection of the lining device and avoiding the impact of the lining device falling off on the equipment and production.

[0046] Specifically, the monitoring member 4 is not limited to a displacement sensor, and other existing monitoring devices capable of detecting the deformation amount, fatigue strength, etc. of the elastic member 3 can be used, which will not be elaborated here.

[0047] As Figure 1 and Figure 2 shown, in some embodiments, there are multiple elastic members 3 arranged in an array between the first plate 1 and the second plate 2 to ensure that the second plate 2 can have a good energy absorption effect on the unloaded ore. There are multiple monitoring members 4 corresponding to the elastic members 3 one by one, so as to realize the one - to - one matching between the monitoring member 4 and the elastic member 3 and ensure the detection accuracy.

[0048] It should be noted that the specific number and layout method of the elastic members 3 can be designed accordingly according to the specifications of the second plate 2 and the position where the second plate 2 mainly receives the ore during ore unloading, etc., so as to ensure that the energy absorption effect on the unloaded ore can be achieved. Similarly, considering the production cost and monitoring accuracy requirements, etc., the specific number of the monitoring members 4 can also be designed accordingly. For example, the monitoring member 4 is only arranged at the position where the second plate 2 mainly receives the ore, or the monitoring member 4 arranged at this position is more than that at other positions, etc., which will not be elaborated here.

[0049] As Figure 2 shown, in some embodiments, the bin lining device further includes a warning device (not shown in the figure). The warning device is installed between the first plate 1 and the second plate 2, and is adapted to give a warning prompt according to the monitoring information of the monitoring member 4, so that the on - site operator can stop ore unloading in time for the maintenance of the lining device, thereby reducing the damage to the bin 5 caused by untimely maintenance.

[0050] Specifically, the warning device is not limited to a sound emitter or a photoelectric alarm. The warning device can be electrically connected to the monitoring member 4, so that the warning device automatically alarms according to the monitoring information of the monitoring member 4, thereby prompting the on - site operator to replace the lining device (mainly the second plate 2 and the elastic member 3), and improving the automatic protection performance of the lining device.

[0051] In some embodiments, the bin lining device of the embodiment of the present utility model may further include a host computer (not shown in the figure). The monitoring member 4 is electrically connected to the host computer. For example, the monitoring member 4 feeds back the monitoring data to the host computer through an optical fiber, so that the host computer collects and analyzes the action mechanism of the lining device during each ore unloading, conducts big data analysis, to better guide the ore unloading and optimize the lining device.

[0052] It should be noted that, for convenience and to improve the installation efficiency, the second plate 2 and the elastic member 3 can be pre-welded and assembled on the ground in advance, and then the whole of them and the first plate 1 are lowered into the bin 5 for installation, reducing the installation and maintenance time.

[0053] As Figures 1 to 4 shown, a mine unloading station according to an embodiment of the present utility model includes a bin 5 and a lining device. The lining device is the lining device of any of the above embodiments. The lining device is connected to the inner wall of the bin 5, and the lining device can completely cover the inner wall of the bin 5. The wall surface of the first plate 1 facing away from the second plate 2 in the lining device presses against the inner wall of the bin 5, that is, the left side wall of the first plate 1 presses against the inner wall of the bin 5.

[0054] According to the mine unloading station of the embodiment of the present utility model, the lining of the bin 5 is designed to adopt a structure formed by the cooperation of the first plate 1, the second plate 2 and the elastic member 3, realizing the integration of the lining device, which can ensure good protection of the inner wall of the bin 5, so as to reduce the ore unloading risk. Therefore, compared with the related art, the ore unloading station adopting this lining device can ensure the production efficiency and service life, and improve the safety.

[0055] It should be noted that, due to the action of the second plate 2 and the elastic member 3, a part of the ore barrier with reverse impact force will be formed in front of the second plate 2 (that is, the right side of the second plate 2 in the figure). Compared with the related art where only the first plate 1 (i.e., the wear-resistant steel plate) directly contacts the ore completely rigidly, the present utility model converts the impact action of the ore into the contact between the ores through the second plate 2 and the elastic member 3, thereby shortening the impact time of the lining device and reducing the impact force, realizing the self-protection of the bin 5 in the unloading station. In addition, the coverage range of the lining device can also be designed accordingly according to the area on the inner wall of the bin 5 that mainly receives the ore during actual ore unloading, taking the energy absorption effect of the unloaded ore and the protection effect of the unloading station as the criterion, which will not be elaborated here.

[0056] As Figure 1 shown, in some embodiments, the mine unloading station further includes a locking member 6. The locking member 6 includes a bolt. An installation hole is provided on the inner wall of the bin 5. The first plate 1 is provided with a first through hole, and the second plate 2 is provided with a second through hole. The bolt passes through the second through hole and the first through hole in sequence and is threadedly engaged with the installation hole to lock the lining device on the inner wall of the bin 5.

[0057] It can be understood that the lining device assembled by the first plate 1, the second plate 2 and the elastic member 3 cooperates with the bolts to form a complete set of pre-assembled components, so as to realize the installation of the lining device on the inner wall of the bin 5 through the quick connection of the bolts with the installation holes reserved on the inner wall of the bin 5. The installation efficiency is high. Therefore, compared with the prior art in which the lining is fixed on the bin 5 by casting, the present utility model can realize the connection between the lining device and the bin 5 by using the locking member 6, which is convenient for maintenance, and due to the energy absorption effect of the second plate 2 and the elastic member 3, the later maintenance amount is also small.

[0058] As Figure 1 and Figure 2 shown, in some embodiments, there are multiple installation holes which are arranged at intervals on the inner wall of the bin 5, there are multiple first through holes which are arranged at intervals along the circumference of the first plate 1, there are multiple second through holes which correspond to the first through holes one by one, and there are multiple locking members 6 which correspond to the installation holes and the first through holes one by one to ensure the connection reliability of the first plate 1 and the second plate 2 on the inner wall of the bin 5. Among them, for the specific number and layout position of the installation holes, the first through holes and the second through holes, they can be designed accordingly according to the specifications of the second plate 2 and the position where the second plate 2 mainly receives the ore during ore unloading, etc., and will not be elaborated here.
