Description

TECHNICAL FIELD

[0001] The utility model relates to mining exploitation equipment technical field, specifically, it relates to a kind of support column base structure suitable for row support and support column base assembly and single support column base and double support column base and three support column base. BACKGROUND

[0002] Row support is an innovative device for temporary support in the process of mining, aiming to improve the safety and efficiency of roadway support operation. Traditional temporary support equipment supports the roof through telescopic support columns, but due to uneven roadway floor, telescopic support columns are prone to sliding or tilting, posing a risk of collapse and high maintenance costs. By introducing guide columns into the device, the stability and safety of the support equipment are optimized. The mechanical strength of the guide column is significantly higher than that of the telescopic support column, which can provide additional support when the support column slides and causes the device to tilt, preventing the device from continuing to tilt, ensuring construction safety and reducing equipment damage and maintenance costs. In addition, the flexibility of the guide column allows it to adapt to height changes when the support moves, thus not hindering the flexible operation of the support.

[0003] In Chinese patent CN109578040B, row support is composed of two supports, and the strip-shaped top beams of the two supports are arranged at intervals. The two supports support the same roof, and when one of them supports the roof, the other moves forward, providing uninterrupted support to the roof. It is composed of a first support, a second support, a driving device, a telescopic support column and a guide column. The guide column is fixedly connected with the support and adapts to the dynamic adjustment of the support through sliding or hinged mechanism. The design height of the guide column is usually slightly lower than that of the telescopic support column, so as to provide sufficient operating space when the support moves forward or backward. During the support operation, the guide column can bear the tilting force of the device, thereby protecting the telescopic support column from bending or breaking. To enhance the stability of the device, the guide column is usually made of hollow or solid high-strength material and contacts the roadway floor through the base, expanding the contact area and enhancing the overall balance of the device. According to the requirements of roadway operation, the guide column can be arranged before or after the support or distributed between multiple telescopic support columns to ensure the stability and flexibility of the device.

[0004] The introduction of guide column in row support solves the problem of sliding and tilting of traditional support equipment in uneven roadway, significantly improving the safety and economy of the support system. Its modular design is easy to adjust, which can adapt to the support needs of different roadways, reducing equipment replacement and adjustment costs. The optimized distribution of guide columns enhances the force distribution of the device, ensuring its stability and reliability in high-load operation. This technology has broad application prospects in mining, roadway support and other fields, especially in complex geological conditions or limited operation space.

[0005] In a mine, rock burst (mine earthquake or rock burst) is an extreme geological phenomenon, when this strong shock wave occurs, the whole mine structure is under great pressure. The hydraulic support system often fails to respond in time in this case, the instantaneous huge pressure generated by the mine earthquake will quickly cause the surrounding rock roof to drop, and produce a violent impact in less than 0.1 second, the adjustment speed of the hydraulic system is far behind this change, resulting in that the support structure cannot effectively resist the impact, and is finally washed out or destroyed.

[0006] This phenomenon shows that the design of the traditional row support system has serious safety hazards, especially in the face of sudden mine earthquake or rock burst, the reaction speed of the hydraulic support column is far from enough, which cannot effectively absorb and disperse the impact energy, resulting in the rapid damage of the support structure. The existing tunneling roadway support is not equipped with effective buffer components, lacks the adaptability to instantaneous impact, and cannot protect the miners and equipment from the serious impact of mine earthquake disaster, which needs to be improved to improve the overall safety and impact resistance.

[0034] It should be noted that the embodiments and the features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0035] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0036] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the terms thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0037] It should be noted that the terms used herein are only for the purpose of describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should also be understood that when the terms "comprise" and / or "include" are used in the specification, they indicate the presence of a feature, step, operation, device, component and / or combination thereof.

[0038] Figure 1 An embodiment of the support column base structure of the present application suitable for row supports is shown, which comprises a seat body, a support column connecting part 20 connected with the support column 10 is formed on the seat body, the support column connecting part 20 is elevated to form a plug-in structure 21, the plug-in structure 21 is used to be inserted into the end of the support column 10, and the support column base structure further comprises a buffer part 30, which is installed in the plug-in structure 21 and used to be placed below the end of the support column 10.

[0039] The technical scheme of the utility model, through setting the plug-in structure 21 formed by lifting in the support column base structure, realizes the effective guidance to the end part of the support column 10. The design of the plug-in structure 21 ensures that the buffer component 30 can be stably installed inside, and the support column 10 moves vertically under the impact load, thereby ensuring the dynamic cooperation of the buffer component 30 and the support column 10. When the mine impact ground pressure or rock burst occurs, the buffer component 30 can quickly contract and absorb huge impact energy, significantly relieving the instantaneous stress of the support column 10, avoiding the damage of the equipment structure. Since the buffer component 30 is placed at the bottom of the plug-in structure 21, more accurately, at the position closest to the surrounding rock floor, the vibration caused by the crushing of the buffer component when the support is impacted is minimized.

[0040] In addition, the buffer component 30 is located below the end part of the support column 10, and its vertical movement path is guided by the plug-in structure 21. When the mine impact ground pressure occurs, the buffer component 30 is quickly contracted in the first time, and the support also quickly drops a distance, so that the powerful impact does not damage the support.

[0041] It should be noted that the independent design of the buffer component 30 and the support column 10 also facilitates quick replacement, and the buffer component 30 reduces the downtime of underground operation. Through the above optimization design, the support column base structure can better adapt to the complex mine operation environment, and significantly improve the safety and reliability of the support system.

[0042] The plug-in structure 21 is the movement guide of the buffer component 30 and the support column 10 in the direction perpendicular to the surrounding rock floor, so that the row support has the energy absorption and impact prevention function, and can be used in various underground working faces such as heading, advance, end, and even coal mining working face with impact ground pressure.

[0043] As a more optional implementation manner, as shown in Figure 1 The bottom of the limiting ring 40 is used for cooperating with the end part of the support column 10 to limit the end part of the support column 10 in the plug-in structure 21. By setting the limiting ring 40 in the support column base structure, the effective limiting of the end part of the support column 10 is realized, so that it remains stable in the plug-in structure 21. The limiting ring 40 is fixedly installed in the plug-in structure 21 and located above the buffer component 30, which can limit the unexpected movement of the end part of the support column 10 when the support column 10 is impacted or subjected to non-vertical load, and prevent the support column 10 from sliding upward out of the plug-in structure 21.

[0044] In use, the end of the support column 10 has the effect of moving downward at the same time as the compression spring is contracted under force, so the diameter of the end of the support column 10 is greater than the diameter of the support column 10. By setting the limit ring 40 to cooperate with the end of the support column 10, the support column 10 is allowed to slide downward when compressed, and is not allowed to move upward, so that it cannot be separated from the seat body.

[0045] More preferably, in the technical solution of Embodiment One, the support column base structure further comprises a limit ring fixing pin 50, the limit ring 40 is fixed in the plug-in structure 21 through the limit ring fixing pin 50, and the limit ring 40 and the plug-in structure 21 are formed with a plug hole structure cooperating with the limit ring fixing pin 50. By setting the limit ring fixing pin 50, the fixing reliability of the limit ring 40 in the plug-in structure 21 is further enhanced. The limit ring fixing pin 50 cooperates with the plug hole structure on the limit ring 40 and the plug-in structure 21 to achieve stable installation of the limit ring 40, avoid displacement or loosening of the limit ring 40 due to impact or vibration, and thus ensure the limiting effect of the end of the support column 10 in the plug-in structure 21. At the same time, this design simplifies the installation and disassembly process of the limit ring 40, and facilitates maintenance of the equipment and replacement of the buffer component 30.

[0046] Optionally, the limit ring 40 is an integral ring structure. As another optional embodiment, the limit ring 40 comprises a plurality of tile-shaped structures, and the plurality of tile-shaped structures form a split ring structure. The integral ring structure of the limit ring 40 has high integrity and can provide stable support and limiting effect, and is suitable for conventional working environments; while the split tile-shaped structure is convenient to disassemble and install, and is particularly suitable for working scenes with limited space or requiring quick disassembly and assembly. The plurality of tile-shaped structures combined to form a split ring structure can ensure that the limit ring 40 improves the installation and maintenance efficiency without reducing the limiting strength. Optionally, in this embodiment, the split ring structure is composed of two tile-shaped structures.

[0047] As shown in Figure 1 In the technical solution of Embodiment One, the buffer component 30 is a spring type buffer component. The spring type buffer component can provide a quantitative and controllable flexible support force, quickly contract when subjected to impact ground pressure, absorb and disperse impact energy, and at the same time, its long-term stable elastic force ensures that the support effect is reliable and the maintenance cost is low. The spring type buffer component has a quantitative and controllable soft support force, which can gently contact the top surrounding rock without using excessive force, and the effect is the best. The spring type buffer component is the simplest and most practical solution, and the spring force is a fixed force that is not easy to change over a long period of time. It is more stable and accurate than hydraulic liquid control, has low cost, and is good for surrounding rock with broken surface and small pressure.

[0048] As shown in Figure 2As shown, the utility model also provides a kind of support column base structure suitable for row support of embodiment two, and the difference between embodiment two and embodiment one is only in that buffer component 30 is rubber type buffer component.

[0049] Preferably, the rubber type buffer component includes an elastic support ring 31 and a plurality of partitions 32 arranged in the elastic support ring 31, and a gas chamber is formed between adjacent two partitions 32. By arranging the elastic support ring 31 and the plurality of partitions 32 in the rubber type buffer component, the energy absorption performance and structural stability are effectively improved. The elastic support ring 31 provides external support force for the buffer component, ensuring that it can maintain stable shape when stressed, and the design of the plurality of partitions 32 forms independent gas chambers inside the support ring 31. These gas chambers can effectively absorb and buffer energy by compression or deformation when subjected to impact load, thereby dispersing the impact force and reducing the stress pressure of the support column 10 and the plug-in structure 21. The layered design of the gas chamber can also prevent the buffer component from losing overall function due to local damage, further improving the reliability of the system. In addition, this structure can adapt to different impact energy absorption requirements by adjusting the number of partitions 32 and the volume of the gas chamber, significantly improving the impact resistance of the row support and the operation safety, and meeting the use requirements in complex mine environments.

[0050] As another optional embodiment not shown in the figure, the buffer component 30 can also be a sheet metal structure impact-resistant energy-absorbing component. The advantage of this type of buffer component is that the impact-resistant energy-absorbing component built by sheet metal structure absorbs impact by its own irreversible deformation, so it does not return impact force to the support column 10, and the impact absorption effect is better. A support column costs nearly ten thousand yuan, and the cost of the sheet metal structure impact-resistant energy-absorbing component is very low. When the sheet metal structure impact-resistant energy-absorbing component is worn out, a new one can be replaced, which can greatly save costs and better solve the cost problem of the support column being easily damaged.

[0051] In addition to the types of buffer component 30 listed above, a threaded tube energy-absorbing component is also feasible.

[0052] More preferably, in the technical solution of embodiment two, an exhaust hole 211 is formed on the plug-in structure 21. The design of the exhaust hole 211 can effectively release the high-pressure gas generated when the buffer component 30 is compressed under stress, avoiding the blocking of the buffer effect of the buffer component 30 due to the inability of the gas to be quickly discharged. This structure significantly improves the dynamic response capability of the buffer component 30, enabling it to quickly contract and yield under sudden loads such as mine impact pressure. It should be noted that when a rubber type buffer component is used, the exhaust hole structure can not be used; when a spring or sheet metal structure impact-resistant energy-absorbing component is used, the exhaust hole structure needs to be considered more.

[0053] Figure 3The embodiment of the support column base assembly suitable for row support frame of the utility model is shown, the support column base assembly comprises a support column base structure, the support column base structure is the support column base structure mentioned above, the support column base assembly comprises a support column 10, a limiting through slot 111 is formed on the insertion part 11 of the insertion part 111 of the insertion structure 21, and the limiting through slot 111 is arranged along the vertical direction;The support column base structure further comprises a limiting pin 60, the limiting pin 60 passes through the insertion structure 21 and the limiting through slot 111 and limits the insertion part 11 in the insertion structure 21.By setting the limiting through slot 111 along the vertical direction on the insertion part 111 of the support column 10, in combination with the design of the limiting pin 60, the limiting movement of the support column 10 in the insertion structure 21 is realized.The limiting pin 60 passes through the insertion structure 21 and the limiting through slot 111, which can effectively prevent the transverse displacement or disengagement of the support column 10 under stress or impact, while allowing its limited vertical movement along the limiting through slot 111 direction.In addition, the matching design of the limiting pin 60 and the limiting through slot 111 can also simplify the disassembly and maintenance of the support column 10, and improve the adaptability of the support column base assembly.

[0054] As shown in Figure 3 The insertion structure 21 is provided with a jack for mounting the limiting pin 60, and the air vent 211 is formed on the jack of the limiting pin 60.

[0055] As shown in Figure 3 As shown in the embodiment, the insertion part 111 of the support column 10 is an additional length section welded at the bottom of the support column 10.As another optional embodiment, the insertion part 111 can also be an integral structure with other parts of the support column 10.

[0056] Optionally, the limiting through slot 111 is processed in two limiting through slots 111 on the same horizontal center line on the insertion part 111, and the circumferential angle between the two limiting through slots 111 is 180°.The limiting pin 60 passes through the round hole of the base side and then passes through the two limiting through slots 111, and presses the lowest circular arc processing surface of the lengthening section limiting through slot 111 of the support column 10.Such structure also has the effect that the support column 10 cannot move upward due to being pressed by the limiting pin 60 during normal use, and the support column 10 moves downward at the same time with the buffer component 30 during impact ground pressure.If the insertion structure 21 is a circular groove, in order to discharge the high pressure gas generated during the process of the energy absorption anti-impact component being crushed, the base limiting pin 60 hole is designed to be large enough to discharge the gas, or the base limiting pin 60 hole is processed into a downwardly extending long hole, and the long hole part can also discharge the gas.Of course, the opening above the insertion structure 21 can also discharge part of the gas.

[0057] It should be noted that the structure of the buffer component 30 installed in the base is simple, and once damaged, the limiting pin 60 is pulled out on the spot at the underground working face, the operating valve is moved to lift the cylinder of the support column 10 and separate it from the base, the damaged buffer component 30 is taken out and a spare part is put in, the operating valve is moved again to lower the support column 10 into the base, the limiting pin 60 is installed, and the replacement of the buffer component is completed. It is easy to replace a buffer component, which can be completed by one person in a few minutes, which is beneficial to the resumption of production.

[0058] As Figure 4 shown, the utility model also provides an implementation mode of single support column base suitable for row support, which comprises a base, and a support column base structure is arranged on the base, and the support column base structure is the above-mentioned support column base structure. The single support column base ensures the stable connection between the support column 10 and the base by arranging a support column base structure on the base. The insertion structure 21 in the support column base structure effectively guides the vertical movement of the support column 10, and cooperates with the buffer component 30 to absorb and buffer energy when stressed, thereby improving the impact resistance of the base and significantly improving the stability and safety of the row support, Figure 2 and Figure 3 the fixed support column mode can be arbitrarily selected in actual use.

[0059] As Figure 5 shown, the utility model also provides another implementation mode of single support column base suitable for row support, which is different from the above-mentioned implementation mode only in that in the implementation mode, the support column base structure is formed in the middle of the base, the guide column connecting parts 80 connected with the two guide columns 70 are respectively formed on the two sides of the support column base structure, and the guide column connecting parts 80 connected with the two guide columns 70 are formed on the two sides of the support column base structure, thereby significantly improving the stability and impact resistance of the overall support. The symmetrical arrangement of the guide column connecting parts 80 uniformly distributes the stress of the equipment, thereby enhancing the balance and adaptability of the support in the complex roadway.

[0060] As an optional implementation mode of the single support column base suitable for row support, the support column connecting part 20 is elevated relative to the guide column connecting part 80 to form the insertion structure 21. As another optional implementation mode of the single support column base suitable for row support, the guide column connecting part 80 and the support column connecting part 20 are elevated to the same height to form the insertion structure 21 in the support column connecting part 20.

[0061] As Figure 6As shown, the utility model also provides a double support column base suitable for the row support, the double support column base includes the base, two support column base structures are arranged on the base at intervals, the base is also provided with the guide column connecting portion 80 connected with the guide column 70, the support column base structure is the above-mentioned support column base structure, and the guide column connecting portion 80 is located between the two support column base structures. By arranging two support column base structures on the base at intervals and arranging the guide column connecting portion 80 connected with the guide column 70 therebetween, the stability and impact resistance of the double support column structure are effectively enhanced. Two support columns 10 are connected with the support column base structures on the base respectively, provide strong support force in the vertical direction, evenly distribute load, and reduce the risk of equipment inclination or instability. The design of the combination of the double support column and the guide column 70 not only optimizes the stress distribution of the support, but also ensures that the buffer component 30 can quickly respond and absorb impact energy under extreme conditions such as mine impact ground pressure, protecting the support from damage.

[0062] As shown in the drawings, Figure 7 The utility model also provides another embodiment of a double support column base suitable for the row support, in which the guide column connecting portion 80 and the support column connecting portion 20 are raised to the same height to form a plug-in structure 21 in the support column connecting portion 20. By designing the guide column connecting portion 80 and the support column connecting portion 20 to the same height and forming the plug-in structure 21 in the support column connecting portion 20, efficient cooperation of the guide column 70 and the support column 10 is realized. The guide column connecting portion 80 is consistent in height with the support column connecting portion 20, making the base structure bear force more evenly and significantly improving the overall stability of the support. In the plug-in structure 21, the support column 10 and the guide column 70 can bear force simultaneously and maintain dynamic response capability, effectively resisting impact load during mine operation.

[0063] As another embodiment of a double support column base suitable for the row support not shown in the drawings, in which the support column connecting portion 20 is raised relative to the guide column connecting portion 80 to form a plug-in structure 21.

[0064] As shown in the drawings, Figure 8 The utility model also provides a three support column base suitable for the row support, which includes a base, three support column base structures are arranged on the base at intervals, two guide column connecting portions 80 connected with the guide column 70 are arranged on the base, the support column base structure is the above-mentioned support column base structure, each guide column connecting portion 80 is arranged between two adjacent support column base structures, and the support column connecting portion 20 is raised relative to the guide column connecting portion 80 to form a plug-in structure 21. Compared with other embodiments, the dense arrangement of more support columns 10 and more guide columns 70 is more suitable for coping with high pressure and strong impact force of the top surrounding rock.

[0065] As Figure 9 shown, the utility model also provides a kind of three support column base suitable for row support another alternative embodiment of support, in this embodiment, guide column connecting portion 80 and support column connecting portion 20 are elevated to the same height and form insertion structure 21 in support column connecting portion 20.

[0066] It needs to be explained that in the above description, "support column connecting portion 20 is elevated relative to guide column connecting portion 80" includes two kinds of implementable structures, the first kind of implementable structure is that guide column connecting portion 80 maintains the same height as in prior art, and only support column connecting portion 20 is elevated;The second kind of implementable structure is that guide column connecting portion 80 is also elevated compared with the same height as in prior art, but the height of support column connecting portion 20 is higher than that of guide column connecting portion 80, and in the second kind of implementable structure, higher guide column connecting portion 80 can also have better fixing effect on guide column.

[0067] It also needs to be explained that all the supports in which support column 10 is perpendicular to the surrounding rock floor lifting, that is, support column 10 does not change the inclination angle with the change of its own height in use can use the technical solution of the utility model.

[0068] Optionally, insertion structure 21 can be square groove. As other alternative embodiments, insertion structure 21 can also be circular groove, and the depth of insertion structure 21 is at least 2-3 times or more than the depth of the mounting hole of the existing base support column or guide column. More preferably, the size of insertion structure 21 should correspond to the size of the end of the support column, so as to help reduce the gap amount, so that the positioning height of insertion structure 21 is lengthened, so that the transverse shaking amount of the fixed support column and guide column 70 is reduced to a very small amount, when the support walks on uneven surrounding rock floor, all support components are vertically dropped and fixed in position according to the position, and no small distance sliding and overturning occurs. The stability of the support is greatly improved. There is no phenomenon of transverse shaking or that the rear base and the front base make the base stack when moving forward. Insertion structure 21 allows buffer component 30 to be placed, and then a small section of support column 10 is also inserted into the groove, so that support column 10 is directly or indirectly pressed above the energy-absorbing member, and the increased insertion structure 21 protects buffer component 30 and provides a downward movement channel for buffer component 30 and support column 10.

[0069] It needs to be explained that when insertion structure 21 is square groove, the four corners of square groove can be used as exhaust passage for stamping of support column 10. When insertion structure 21 is cylindrical groove, exhaust passage with the above-mentioned exhaust hole 211 should be considered. The two kinds of exhaust passages can be suitable for spring type buffer component or rubber type buffer component.
