Description

Technical Field

[0001] This application relates to the field of coal tunneling technology, and more particularly to a transfer machine support assembly and a coal mining system. Background Technology

[0002] In actual coal mining operations, the rigid-frame tail-end pull-away winches currently in widespread use have a series of drawbacks in their original design that urgently need to be addressed. Firstly, the original winches are quite heavy, and the traditional method of mounting them at the tail of the bridge transfer conveyor greatly limits the lifting and lowering flexibility of the downstream equipment. This results in a very limited range of adjustment for the overlap height between the downstream equipment and the bridge transfer conveyor during continuous transport. Faced with complex and changing roadway conditions, such as undulating roadways or changes in geological structure, the equipment cannot adjust the overlap height in a timely and effective manner, leading to operational obstruction and affecting the smoothness of coal mining operations.

[0003] Secondly, the original design led to the thorny problem of the bottom chain of the supporting equipment pulling back coal after continuous transportation. During coal transportation, a large amount of coal was continuously pulled back by the bottom chain, which not only aggravated the wear and tear on the equipment and reduced the efficiency of coal transportation, but also caused equipment failure in severe cases, disrupting the continuity of production and causing unnecessary economic losses to coal mine production.

[0004] Furthermore, during the roadway slope adjustment operation, the inability to flexibly adjust the height of the downstream equipment frequently causes interference between the bridge-type transfer conveyor and the rigid frame at the roadway roof or floor. This interference not only hinders the normal advancement of the downstream equipment during continuous transport but, more seriously, may lead to the breakage of the intermediate frame of the bridge-type transfer conveyor, posing a significant safety hazard. In addition, when the downstream equipment moves forward during continuous transport, the winch's anchors exert a downward horizontal force on the floor. In the event of a broken floor, this force will further exacerbate the damage, severely impacting project quality and hindering standardized construction at the coal mine site. Utility Model Content

[0005] The present invention introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This part of the present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the first aspect of this utility model provides a transfer machine support assembly.

[0008] The second aspect of this utility model provides a coal mining system.

[0009] In view of this, a rigid frame tail assembly is provided according to a first aspect of the embodiments of this application, wherein the transfer machine is configured to be disposed on the rigid frame tail assembly and move along the length direction of the rigid frame tail assembly;

[0010] A protective cover, which is connected to one end of the rigid frame tail assembly;

[0011] A mounting base is connected to one end of the rigid frame tail assembly near the protective cover;

[0012] A winch, which is connected to the fixed base.

[0013] In one feasible implementation, the fixing base includes:

[0014] A top I-beam is connected to one end of the rigid frame tail assembly and is arranged at the top.

[0015] Bottom I-beam, which is connected to one end of the rigid frame tail assembly and is arranged at the bottom;

[0016] A protective plate, which is connected to the rigid frame tail assembly and is arranged at the bottom of the bottom I-beam;

[0017] A vertical plate, which is connected to the top I-beam and the bottom I-beam;

[0018] The winch is connected to the vertical plate.

[0019] In one possible implementation, the top I-beam is inclined relative to the length direction of the rigid frame tail assembly.

[0020] In one feasible implementation, the winch is connected to the vertical plate by bolts and pins.

[0021] In one feasible implementation, the transfer machine support assembly further includes:

[0022] A rolling tow bar is mounted on the rigid frame tail assembly to support the transfer machine.

[0023] A second aspect of the embodiments of this application provides a coal mining system, comprising:

[0024] The transfer machine support assembly as described in any of the above technical solutions;

[0025] A bridge-type transfer machine is mounted on the rigid frame tail assembly of the transfer machine support assembly and moves along the length of the rigid frame tail assembly.

[0026] In one feasible implementation, the coal mining system further includes:

[0027] A lifting assembly, connected to the bridge transfer machine, is used to lift the bridge transfer machine.

[0028] In one feasible implementation, the lifting assembly includes at least two hydraulic cylinders connected to the tail of the bridge transfer machine.

[0029] In one feasible implementation, the coal mining system further includes:

[0032] Compared with the prior art, the present invention has at least the following beneficial effects:

[0033] The transfer machine support assembly provided in this application includes a rigid frame tail assembly, a protective cover, a fixed base, and a winch. Based on this, the transfer machine support assembly provided in this application significantly improves upon the design by adjusting the winch's installation position from the bridge-type transfer machine tail to the rigid frame tail. Therefore, during coal mining, the bridge-type transfer machine is movably mounted on the rigid frame tail assembly. In operation, the rigid frame tail assembly is fixed, and the winch is connected to the rigid frame tail assembly and is also fixed. This fundamentally adjusts the winch's force direction, effectively reducing restrictions on the lifting and lowering of downstream equipment, and significantly expanding the adjustment range of the overlap height between the downstream equipment and the bridge-type transfer machine. This provides crucial support for solving the problem of coal being pulled back by the bottom chain of the downstream equipment during continuous transportation. Meanwhile, the bridge-type transfer conveyor does not have a winch, eliminating the need to move the winch during movement and lifting. This makes the bridge-type transfer conveyor more flexible, and significantly improves the adjustment range of the overlap height between the supporting equipment and the bridge-type transfer conveyor after continuous transport. This allows it to easily handle various complex roadway conditions, making the equipment operate more smoothly and effectively reducing various malfunctions caused by overlap issues. Furthermore, the phenomenon of coal being pulled back by the bottom chain of the supporting equipment is completely eliminated after continuous transport, greatly improving coal transport efficiency, significantly reducing equipment wear, effectively extending the overall service life of the equipment, and fully ensuring the stability of equipment operation.

[0040] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0041] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0042] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0043] like Figure 1As shown, according to a first aspect of the embodiments of this application, a rigid frame tail assembly 110 is provided, a transfer machine is used to be mounted on the rigid frame tail assembly 110 and move along the length direction of the rigid frame tail assembly 110; a protective cover 120 is connected to one end of the rigid frame tail assembly 110; a fixed seat 130 is connected to one end of the rigid frame tail assembly 110 near the protective cover 120; and a winch 140 is connected to the fixed seat 130.

[0044] The transfer machine support assembly provided in this application embodiment includes a rigid frame tail assembly 110, a protective cover 120, a fixed base 130, and a winch 140. Based on this, the transfer machine support assembly provided in this application embodiment innovatively adjusts the installation position of the winch 140 from the tail of the bridge transfer machine to the tail of the rigid frame machine. Therefore, during coal mining, the bridge transfer machine is movably mounted on the rigid frame tail assembly 110. In the operating state, the rigid frame tail assembly 110 is in a fixed state, and the winch 140 is connected to the rigid frame tail assembly 110. The fixed state of the winch 140 fundamentally adjusts the force direction of the winch 140, effectively reducing the restrictions on the lifting and lowering of the downstream supporting equipment, and significantly expanding the adjustment range of the overlap height between the downstream supporting equipment and the bridge transfer machine. This provides key support for solving the problem of coal being pulled back by the bottom chain of the downstream supporting equipment during continuous transportation. Meanwhile, the bridge-type transfer conveyor does not have a winch 140, meaning the winch 140 does not need to move during movement and lifting. This makes the bridge-type transfer conveyor more flexible, and the adjustment range of the overlap height between the supporting equipment and the bridge-type transfer conveyor is significantly improved after continuous transportation. This allows it to easily cope with various complex roadway conditions, making the equipment operate more smoothly and effectively reducing various failures caused by overlap problems. Furthermore, the phenomenon of coal being pulled back by the bottom chain of the supporting equipment is completely solved after continuous transportation, significantly improving coal transportation efficiency, significantly reducing equipment wear, effectively extending the overall service life of the equipment, and fully ensuring the stability of equipment operation.

[0045] The transfer conveyor support assembly provided in this application successfully avoids interference between the bridge transfer conveyor and the rigid frame of the roadway roof or bottom by changing the installation position of the winch 140. This eliminates the possibility of frame breakage at the source, effectively ensuring the normal operation of the equipment, greatly reducing safety risks, and creating a safer and more reliable working environment for coal mine workers. Furthermore, the new installation method significantly reduces the damage to the floor plate caused by the winch 140, further minimizing safety hazards caused by floor plate breakage and comprehensively improving operational safety.

[0046] The lifting and lowering limitations of the 140 pairs of rear auxiliary equipment in the transfer machine support assembly winch provided in this embodiment are significantly reduced. In critical operations such as roadway slope adjustment, equipment operation becomes simpler, faster, more efficient, and more precise, effectively reducing downtime caused by equipment problems and significantly improving the overall efficiency of coal mining operations. At the same time, the engineering quality and on-site standardization level are also significantly improved, laying a solid foundation for the smooth operation of subsequent coal mine production.

[0047] The transfer machine support assembly provided in this application embodiment can protect the rigid frame tail assembly 110 by setting the protective cover 120. It is connected to the rigid frame tail assembly 110 by the fixing seat 130, which facilitates the fixing of the winch 140 and reduces the probability of the winch 140 becoming loose or detached.

[0048] Understandably, winch 140 can be used to pull the tail of the engine during the extension of the belt.

[0049] like Figure 1 As shown, in one feasible embodiment, the fixed base 130 includes: a top I-beam 131, which is connected to one end of the rigid frame tail assembly 110 and arranged at the top; a bottom I-beam 132, which is connected to one end of the rigid frame tail assembly 110 and arranged at the bottom; a guard plate 133, which is connected to the rigid frame tail assembly 110 and arranged at the bottom of the bottom I-beam 132; and a vertical plate 134, which is connected to the top I-beam 131 and the bottom I-beam 132; wherein, the winch 140 is connected to the vertical plate 134.

[0050] In this technical solution, the structural composition of the fixing seat 130 is further provided. The fixing seat 130 may include a top I-beam 131, a bottom I-beam 132, a guard plate 133, and a vertical plate 134. The top I-beam 131, the bottom I-beam 132, and the vertical plate 134 can form a frame structure. Then, the winch 140 is connected to the vertical plate 134 to complete the fixing of the winch 140 and ensure the reliability of the fixing of the winch 140.

[0051] In this technical solution, the fixed base 130 may also include a protective plate 133, which can protect the bottom of the fixed base 130 and reduce the probability of the winch 140 interfering with other devices.

[0052] like Figure 1 As shown, in one feasible embodiment, the top I-beam 131 is inclined relative to the length direction of the rigid frame tail assembly 110. This arrangement allows for more space at the top of the rigid frame tail assembly 110, and the mounting base 130 can avoid other equipment or components, ensuring the reliability of the coal mining system.

[0053] like Figure 1 As shown, in one feasible embodiment, the winch 140 is connected to the vertical plate 134 by bolts 160 and pins. This arrangement makes the fixation of the winch 140 more reliable.

[0054] like Figure 1 As shown, in one feasible embodiment, the transfer machine support assembly further includes a rolling drag bar 150, which is disposed on the rigid frame tail assembly 110 for supporting the transfer machine.

[0055] In this technical solution, considering that bridge transfer machines usually have a certain length and are prone to collapse, the transfer machine support assembly can also include a rolling drag bar 150. The rolling drag bar 150 can provide secondary support for the bridge transfer machine, ensuring the reliability of the coal mining system operation.

[0056] like Figure 1 As shown, a coal mining system is proposed according to a second aspect of the embodiments of this application, comprising: a transfer machine support assembly as described in any of the above technical solutions; a bridge transfer machine, the bridge transfer machine being disposed on the rigid frame tail assembly 110 of the transfer machine support assembly and moving along the length direction of the rigid frame tail assembly 110.

[0057] The coal mining system provided in this application embodiment includes the transfer machine support assembly of any of the above-described technical solutions, and therefore possesses all the beneficial effects of the transfer machine support assembly of the above-described technical solutions.

[0058] The coal mining system provided in this application embodiment includes a bridge-type transfer conveyor and a transfer conveyor support assembly. The transfer conveyor support assembly includes a rigid frame tail assembly 110, a protective cover 120, a fixed base 130, and a winch 140. Based on this, the transfer conveyor support assembly provided in this application embodiment innovatively adjusts the installation position of the winch 140 from the tail of the bridge-type transfer conveyor to the tail of the rigid frame conveyor. Therefore, during coal mining, the bridge-type transfer conveyor is movably mounted on the rigid frame tail assembly 110. In the operating state, the rigid frame tail assembly 110 is in a fixed state, and the winch 140 is connected to the rigid frame tail assembly 110. The fixed state of the winch 140 fundamentally adjusts the force direction of the winch 140, effectively reducing the restrictions on the lifting and lowering of downstream auxiliary equipment, and significantly expanding the adjustment range of the overlap height between the continuous transport downstream auxiliary equipment and the bridge-type transfer conveyor. This provides key support for solving the problem of coal being pulled back by the bottom chain of the continuous transport downstream auxiliary equipment. Meanwhile, the bridge-type transfer conveyor does not have a winch 140. During movement and lifting, the bridge-type transfer conveyor does not require the winch 140 to move, making its movement more flexible. After continuous transport, the adjustment range of the overlap height between the supporting equipment and the bridge-type transfer conveyor is significantly improved, easily handling various complex roadway conditions, making the equipment operate more smoothly and effectively reducing various malfunctions caused by overlap problems. At the same time, the phenomenon of coal being pulled back by the bottom chain of the supporting equipment after continuous transport is completely solved, significantly improving coal transportation efficiency, significantly reducing equipment wear, effectively extending the overall service life of the equipment, and fully ensuring the stability of equipment operation. It is understandable that the bridge-type transfer conveyor is used to transfer materials transported from the face scraper conveyor to the belt conveyor.

[0059] In one feasible implementation, the coal mining system further includes a lifting assembly connected to the bridge transfer conveyor for lifting the bridge transfer conveyor.

[0060] In this technical solution, the coal mining system may also include a lifting assembly. The lifting assembly is connected to the bridge transfer conveyor, which can lift the bridge transfer conveyor, especially its tail section. This allows the coal mining system to coordinate with the position of the belt conveyor, optimize the material transfer path, cope with undulating roadway floors or changes in geological conditions, and facilitate equipment inspection, maintenance, or component replacement. Furthermore, by placing the winch 140 on the rigid frame tail assembly 110 instead of on the bridge transfer conveyor, the lifting weight can be reduced, making the lifting of the bridge transfer conveyor safer.

[0061] In one feasible implementation, the lifting assembly includes at least two hydraulic cylinders connected to the tail of the bridge transfer conveyor. This arrangement ensures that the bridge transfer conveyor receives a temperature-controlled lifting force, making the coal mining system safer to operate.

[0062] In one feasible implementation, the coal mining system further includes: a downstream auxiliary device connected to the bridge transfer conveyor, used to drive the bridge transfer conveyor to move along the length of the rigid frame tail assembly 110. This arrangement facilitates the movement of the bridge transfer conveyor.

[0063] In one feasible implementation, the supporting equipment includes an integrated anchor transport machine.

[0064] This technical solution further specifies the types of supporting equipment, which may include an integrated anchor-transfer and loading machine. By selecting this integrated machine, roadway anchoring and support can be completed simultaneously, ensuring operational safety. Anchoring operations can be completed while the tunneling machine advances forward, closely following the working face, without the need for separate support equipment and procedures. This "synchronous tunneling and support" mode significantly shortens support lag time, reduces the unsupported roof distance, and fundamentally improves the safety of the tunneling face.
