Description

Technical Field

[0001] This invention relates to the field of coal mining machine technology, and in particular to a coal mining machine travel system. Background Technology

[0002] In a fully mechanized coal mining face, the coal mining machine moves back and forth along the guide rails of a scraper conveyor to complete continuous coal cutting operations. Traditional coal mining machine guidance systems generally adopt a "pin-rail-pin-row" structure, where pin rails are installed on the central trough of the scraper conveyor, with regularly distributed pin holes; pin rows or traction sprockets are installed on the coal mining machine body to mesh with these pin rails. The forward and backward movement of the coal mining machine is achieved by driving the pin rows or sprockets to engage with the pin holes of the pin rails via a traction mechanism.

[0003] However, the pin-rail system has several drawbacks in the relevant technology: First, the pins and pin holes generate severe impacts and vibrations during engagement and disengagement, resulting in high operating noise and exacerbating equipment fatigue damage. Second, because the traction mechanism is an intermittent meshing transmission, the coal mining machine has poor movement stability and is prone to "creeping" or shaking, affecting the quality of coal cutting. Summary of the Invention

[0004] This invention provides a coal mining machine walking system to solve the problems of large impact and severe wear in the existing pin rail system, and to achieve stable, low-noise, and continuous traction operation of the coal mining machine.

[0005] An embodiment of the present invention discloses a coal mining machine travel system, comprising:

[0006] A coal mining machine includes a body, a guide assembly, and a sliding shoe. The guide assembly and the sliding shoe are both located on one side of the body in the width direction. The guide assembly and the sliding shoe are arranged sequentially along the length direction of the body. The guide assembly includes a first sliding part.

[0007] A scraper conveyor includes a guide rail and a guide chain. The guide chain is fixedly connected to a slipper. A first sliding part is slidably engaged with the guide rail. A first channel is provided inside the guide rail. The guide chain is movably disposed in the first channel so as to drive the coal mining machine to move along the guide rail through the slipper.

[0008] In some embodiments, the guiding component includes:

[0009] Mounting base, which is fixedly connected to the machine body;

[0010] A slider is movably mounted on the mounting base along the height direction of the body, and the bottom of the slider is provided with a groove to form the first sliding part.

[0011] In some embodiments, the guiding assembly further includes a guide hook that is movable relative to the mounting base along the height direction of the machine body. The guide hook includes a hook portion, and a guide groove is provided on the side of the guide rail adjacent to the coal mining machine. The hook portion is slidably connected to the guide groove.

[0012] In some embodiments, the guide hook includes a root portion that is fixedly connected to the slider, and the mounting base includes a second sliding portion that extends along the height direction of the body, wherein the root portion or the slider is slidably connected to the second sliding portion.

[0013] In some embodiments, the slider is provided with two spaced-apart third sliding portions, the two second sliding portions correspond one-to-one with the two third sliding portions, a first groove is defined between the two third sliding portions, and the root portion is disposed in the first groove and fixedly connected to the slider.

[0014] The two second sliding portions are spaced apart to define the second groove, and the third sliding portion and the root portion are slidably disposed in the second groove.

[0015] In some embodiments, the guide hook includes a limiting portion, the top end of which is connected to the bottom end of the root portion, and the bottom end of which is inclined toward the mounting base and extends below the mounting base to limit the movement of the guide hook in the height direction of the body.

[0016] In some embodiments, there are two guide components and two skis, with the two skis spaced apart and the two guide components located between the two skis.

[0017] In some embodiments, the body is provided with a mounting groove, and the mounting base is detachably disposed in the mounting groove.

[0018] In some embodiments, the slider has reinforcing ribs on the side opposite to the mounting base, and multiple reinforcing ribs are spaced apart.

[0019] In some embodiments, the guide rail is provided with a second channel, which is located below the first channel, and both ends of the second channel are connected to the first channel to form an annular channel, and the guide chain is rotatably disposed within the annular channel.

[0020] The coal mining machine traveling system of this invention employs a sliding engagement between a first sliding part and a guide rail for guidance, while a sliding shoe is slidably positioned in a first channel. The entire movement process involves continuous contact and no meshing action, completely eliminating the impact and vibration caused by periodic engagement and disengagement in traditional pin-rail systems. This significantly reduces the noise level of the coal mining machine during operation, improves the underground working environment, reduces dynamic impact loads on the machine body, guide rails, and related structures, effectively alleviates fatigue damage to the equipment, and improves the overall structural reliability and service life of the machine.

[0021] Secondly, the coal mining machine walking system of this embodiment of the invention achieves continuous traction through the fixed connection between the guide chain and the sliding shoe, and the traction force output is stable and continuous without intermittent sudden changes; at the same time, the guide component provides stable sliding support. The two work together to ensure that the coal mining machine achieves uniform and stable reciprocating movement on the guide rail, which fundamentally avoids the "crawling" and shaking phenomenon caused by meshing gaps in traditional systems, improves walking accuracy and running stability, and is conducive to achieving stable and high-quality continuous coal cutting operations.

[0022] Therefore, the coal mining machine walking system of this embodiment of the invention has the advantages of smooth guidance, continuous traction, low noise and wear resistance, and reliable operation. Attached Figure Description

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following is a reference appendix. Figures 1 to 3 The coal mining machine traveling system 100 of an embodiment of the present invention is described.

[0037] The coal mining machine traveling system 100 of this embodiment includes a coal mining machine 1 and a scraper conveyor 2.

[0038] The coal mining machine 1 includes a body 11, a guide assembly 12 and a sliding shoe 13. The guide assembly 12 and the sliding shoe 13 are both located on one side of the width direction of the body 11. The guide assembly 12 and the sliding shoe 13 are arranged sequentially along the length direction of the body 11. The guide assembly 12 includes a first sliding part 120.

[0039] The scraper conveyor 2 includes a guide rail 21 and a guide chain. The guide chain is fixedly connected to the slipper 13. The first sliding part 120 is slidably engaged with the guide rail 21. The guide rail 21 is provided with a first channel 211. The guide chain is movably disposed in the first channel 211 so as to drive the coal mining machine 1 to move along the guide rail 21 through the slipper 13.

[0040] For ease of description, the technical solution of this application will be described below with the length direction of the body 11 as the front-back direction, the width direction of the body 11 as the left-right direction, and the height direction of the body 11 as the up-down direction. The left-right, up-down, and front-back directions are as follows: Figure 2 As shown.

[0041] For example, the guide assembly 12 and the slipper 13 are both located on the left side of the machine body 11, and the coal mining assembly 10 is located on the right side of the machine body 11. The guide assembly 12 and the slipper 13 are arranged sequentially in the front-to-back direction.

[0042] The first sliding part 120 in the guide assembly 12 is in sliding engagement with the guide rail 21 on the scraper conveyor 2, thereby achieving precise guidance and stable support for the running direction of the coal mining machine 1. At the same time, the slipper 13, through its fixed connection with the guide chain, enables the movement of the guide chain on the scraper conveyor 2 to effectively drive the entire coal mining machine 1 to move forward or backward synchronously along the guide rail 21.

[0043] The guide rail 21 has a first channel 211 inside, in which the guide chain is movably disposed. The slipper 13 is fixedly connected to the guide chain. Thus, the reciprocating movement of the guide chain within the first channel 211 drives the slipper 13 and the entire coal mining machine 1 to move along the extension direction of the guide rail 21. This conceals the guide chain inside the guide rail 21, forming a closed transmission path. This effectively prevents impurities such as coal dust and gravel from entering the transmission area, reducing chain wear and jamming risks, improving transmission reliability and service life. Simultaneously, it enhances the overall structural compactness and safety, avoids interference from external foreign objects, and ensures stable operation of the coal mining machine 1 under harsh working conditions.

[0044] In related technologies, the pin rail system has many defects: First, the pin row and pin hole generate severe impact and vibration during engagement and disengagement, resulting in high operating noise and exacerbating equipment fatigue damage. Second, because the traction mechanism is an intermittent meshing transmission, the coal mining machine 1 has poor movement stability and is prone to "creeping" or shaking, affecting the coal cutting quality.

[0045] The coal mining machine traveling system 100 of this embodiment uses a sliding engagement between the first sliding part 120 and the guide rail 21 for guidance, while the sliding shoe 13 is slidably positioned in the first channel 211. The entire movement process is a continuous contact without meshing action, completely eliminating the impact and vibration caused by periodic meshing and disengagement in traditional pin rail systems. This significantly reduces the noise level of the coal mining machine 1 during operation, improves the underground working environment, and reduces the dynamic impact load on the machine body 11, guide rail 21, and related structures, effectively alleviating fatigue damage to the equipment and improving the overall structural reliability and service life of the machine.

[0046] Secondly, the coal mining machine walking system 100 of this embodiment of the invention achieves continuous traction through the fixed connection between the guide chain and the sliding shoe 13, and the traction force output is stable and continuous without intermittent sudden changes; at the same time, the guide component 12 provides stable sliding support. The two work together to ensure that the coal mining machine 1 achieves uniform and stable reciprocating movement on the guide rail 21, which fundamentally avoids the "crawling" and shaking phenomenon caused by meshing gaps in traditional systems, improves walking accuracy and running stability, and is conducive to achieving stable and high-quality continuous coal cutting operations.

[0047] Therefore, the coal mining machine walking system 100 of this embodiment has the advantages of smooth guidance, continuous traction, low noise and wear resistance, and reliable operation.

[0048] In some embodiments, such as Figure 2 As shown, the guide assembly 12 includes a mounting base 121 and a slider 122. The mounting base 121 is fixedly connected to the body 11. The slider 122 is movably mounted on the mounting base 121 along the height direction of the body 11, and the bottom of the slider 122 is provided with a groove to form a first sliding part 120.

[0049] The mounting base 121 is fixedly connected to the body 11 of the coal mining machine 1, ensuring the stability and reliability of the entire guide assembly 12. For example, the mounting base 121 is connected to the body 11 of the coal mining machine 1 by bolts.

[0050] The lower end of the slider 122 is provided with a groove, which is the first sliding part 120, and it forms a sliding fit with the guide rail 21 on the scraper conveyor 2.

[0051] In the coal mining machine walking system 100 of this embodiment, the slider 122 is movably mounted on the mounting base 121 in the vertical direction, forming an adjustable connection structure. This allows the slider 122 to move within a certain range in the vertical direction relative to the mounting base 121. When the working face is uneven or there is a height deviation in the installation of the guide rail 21, the slider 122 can automatically adapt to the local height changes of the guide rail 21, playing a certain role in buffering and adaptive adjustment, maintaining continuous contact and stable sliding cooperation between the first sliding part 120 and the guide rail 21, thereby improving the operational stability of the coal mining machine 1 under complex geological conditions.

[0052] In some embodiments, such as Figure 3 As shown, the guide assembly 12 also includes a guide hook 123. The guide hook 123 can move relative to the mounting base 121 along the height direction of the machine body 11. The guide hook 123 includes a hook part 1231. The guide rail 21 is provided with a guide groove 212 on the side adjacent to the coal mining machine 1. The hook part 1231 is slidably connected to the guide groove 212.

[0053] The hook portion 1231 of the guide hook 123 forms a hook-shaped structure, which matches the guide groove 212 set on the side of the guide rail 21 adjacent to the coal mining machine 1. After the hook portion 1231 is embedded in the guide groove 212, it slides along its length direction. This not only achieves precise guidance for the forward and backward movement of the coal mining machine 1, but also provides reliable limit constraints in the vertical direction, preventing the coal mining machine 1 from jumping or derailing due to vibration, impact or tilting conditions during operation. This significantly improves the stability and safety of the coal mining machine walking system 100.

[0054] Furthermore, the guide hook 123 and the mounting base 121 form an adjustable connection structure, which allows it to move relative to the mounting base 121 in the vertical direction, thus giving the guide hook 123 a certain adaptive adjustment capability. When the coal mining machine 1 travels to a section of the guide rail 21 where there is a height deviation, uneven installation, or local deformation, the guide hook 123 can float up and down synchronously with the change of the guide rail 21 profile, ensuring that the hook part 1231 is always stably embedded in the guide groove 212 and maintains a sliding connection state.

[0055] Furthermore, both the guide hook 123 and the slider 122 have the ability to be adjusted in the vertical direction. The two work together to enable the guide assembly 12 to achieve multi-degree-of-freedom constraints while also having good adaptability, stability and reliability, further optimizing the walking performance of the coal mining machine 1 under long-distance, high-load and variable working conditions.

[0056] In some embodiments, the guide hook 123 includes a root 1232, which is fixedly connected to the slider 122, and the mounting base 121 includes a second sliding portion 1211 extending along the height direction of the body 11, with the root 1232 or the slider 122 slidably connected to the second sliding portion 1211.

[0057] The root 1232 of the guide hook 123 is fixedly connected to the slider 122, so that the guide hook 123 moves synchronously with the slider 122. The mounting base 121 is provided with a second sliding part 1211 extending in the vertical direction. The root 1232 of the guide hook 123 or the slider 122 is provided with a corresponding sliding structure so as to form a sliding engagement with the second sliding part 1211, so that the guide hook 123 and the slider 122 can move synchronously relative to the mounting base 121 in the vertical direction. For example, the root 1232 or the slider 122 is provided with a protrusion, and the second sliding part 1211 is a groove, in which the protrusion slides into the groove.

[0058] The coal mining machine walking system 100 of this embodiment of the invention, by sliding the root 1232 or the slider 122 to the second sliding part 1211, enables both the hook part 1231 of the guide hook 123 and the slider 122 to have the ability to float up and down, which can adapt to the height change or installation error of the guide rail 21, avoid jamming, ensure smooth sliding, and at the same time maintain the stable limit of the guide rail 21, thereby improving the stability and reliability of the coal mining machine 1.

[0059] In some embodiments, the slider 122 is provided with two spaced third sliding portions 1221, two second sliding portions 1211 correspond one-to-one with the two third sliding portions 1221, and a first groove 1222 is defined between the two third sliding portions 1221. The root portion 1232 is disposed in the first groove 1222 and is fixedly connected to the slider 122.

[0060] Two second sliding portions 1211 are spaced apart to define a second groove 1212, and a third sliding portion 1221 and a root portion 1232 are slidably disposed in the second groove 1212.

[0061] The slider 122 is provided with two spaced-apart third sliding parts 1221, forming a first groove 1222 between them. The root 1232 of the guide hook 123 is located in the first groove 1222 and is fixedly connected to the slider 122, realizing the integrated assembly of the guide hook 123 and the slider 122. At the same time, the mounting base 121 is provided with two second sliding parts 1211, which are spaced-apart to form a second groove 1212. The width of the first groove 1222 is smaller than the width of the second groove 1212. The third sliding parts 1221 and the root 1232 of the guide hook 123 both extend into the second groove 1212. The two third sliding parts 1221 cooperate with the two second sliding parts 1211 one by one, so that the slider 122 and the guide hook 123 fixed thereto can slide relative to the mounting base 121 in the vertical direction.

[0062] The coal mining machine walking system 100 of this embodiment of the invention firstly achieves smooth movement and precise guidance through double-sided sliding guides, effectively preventing jamming or uneven wear, improving stability and load-bearing capacity during the up and down adjustment process, and enabling the hook portion 1231 of the first sliding part 120 and the guide hook 123 to synchronously adapt to the height change of the guide rail 21, ensuring continuous and stable cooperation with the guide rail 21, and improving the reliability and adaptability of the coal mining machine 1 operation.

[0063] Secondly, in the coal mining machine walking system 100 of this embodiment, the root 1232 of the guide hook 123 is set in the first groove 1222, and the guide hook 123 and the third sliding part 1221 are nested in the second groove 1212 of the mounting base 121, so as to realize the compact stacked arrangement of multiple components, effectively utilize space, reduce the occupied size, and make the overall structure of the guide assembly 12 more compact, which is convenient for installation and arrangement in the limited space of the coal mining machine 1.

[0064] In some embodiments, the guide hook 123 includes a limiting portion 1233, the top end of the limiting portion 1233 being connected to the bottom end of the root portion 1232, and the bottom end of the limiting portion 1233 being inclined toward the mounting base 121 and extending below the mounting base 121, so as to limit the movement of the guide hook 123 in the height direction of the body 11.

[0065] A limiting part 1233 is provided between the root part 1232 and the hook part 1231. The top end of the limiting part 1233 is straight so as to connect with the root part 1232. The bottom end of the limiting part 1233 extends downward towards the mounting base 121 to form a downward protruding shoulder structure.

[0066] When the guide hook 123 moves upward relative to the mounting base 121 in the vertical direction, the inclined part of the limiting part 1233 gradually approaches the bottom of the mounting base 121 and eventually contacts it, thereby limiting the guide hook 123 from moving upward and realizing the mechanical limit of the floating stroke of the guide hook 123. This design ensures that the guide hook 123 has a certain vertical adjustment capability while preventing it from floating too much and disengaging from the mounting base 121, thereby avoiding the coal mining machine 1 from derailing.

[0067] In some embodiments, there are two guide components 12 and two slippers 13, with the two slippers 13 spaced apart and the two guide components 12 disposed between the two slippers 13.

[0068] Two slippers 13 are spaced apart in the front-to-back direction, and two guide components 12 are located between them and arranged sequentially in the front-to-back direction.

[0069] The coal mining machine walking system 100 of this embodiment of the invention has two guide components 12 disposed between two slippers 13 to form a multi-point support structure on one side of the coal mining machine 1. The two slippers 13 provide front and rear two-point walking support, and the two guide components 12 in the middle provide intermediate guidance and load bearing, effectively dispersing the force and improving the stability and anti-overturning ability of the coal mining machine 1.

[0070] Meanwhile, the central arrangement of the guide component 12 helps to balance the forces on the front and rear sides, reduce uneven wear, and ensure reliable sliding cooperation between the coal mining machine 1 and the guide rail 21. The overall structure is reasonable and has a high space utilization rate. Under the premise of ensuring strength and stability, it improves the adaptability and operational reliability of the coal mining machine 1 under complex working conditions.

[0071] In some embodiments, the body 11 is provided with a mounting groove 111, and the mounting seat 121 is detachably disposed in the mounting groove 111. The mounting seat 121 is fixedly installed in the mounting groove 111 by bolts. When the guide assembly 12 is worn or requires maintenance, the mounting seat 121 can be directly removed from the mounting groove 111 without disassembling the body 11, resulting in high maintenance efficiency and short downtime.

[0072] Meanwhile, the coal mining machine walking system 100 of this embodiment embeds the mounting base 121 into the mounting groove 111, which has a compact structure, makes full use of the local space of the machine body 11, avoids the external protruding structure occupying extra space, and is conducive to the compactness of the overall layout.

[0073] In some embodiments, the slider 122 is provided with a reinforcing rib 1223 on the side opposite to the mounting base 121, and a plurality of reinforcing ribs 1223 are spaced apart.

[0074] The slider 122 has multiple spaced reinforcing ribs 1223 on the side away from the mounting base 121. These reinforcing ribs 1223 are arranged along the front-back direction, which enhances the overall rigidity and structural strength of the slider 122 and effectively prevents the slider 122 from deforming when subjected to large loads or impacts, thereby improving the reliability of the guide assembly 12 and ensuring the normal and stable operation of the coal mining machine 1.

[0075] In some embodiments, the guide rail 21 is provided with a second channel 213, which is located below the first channel 211, and both ends of the second channel 213 are connected to the first channel 211 to form an annular channel. The guide chain is rotatably disposed within the annular channel. The scraper conveyor 2 is provided with a drive member, which is connected to the guide chain to drive the guide chain to rotate.

[0076] The second channel 213 is located below the first channel 211, and its two ends are connected to the first channel 211, together forming a closed annular channel. The guide chain is rotatably disposed in the annular channel, forming a closed loop transmission channel.

[0077] The drive component is connected to the guide chain and is used to drive the guide chain to rotate in the annular channel of the guide rail 21. The drive component is usually a sprocket or a drive motor assembly. It transmits power to the guide chain through meshing and transmission, thereby driving the fixed slipper 13 and the entire coal mining machine 1 to move back and forth along the guide rail 21.

[0078] The coal mining machine traveling system 100 of this embodiment of the invention achieves automatic guidance and support of the guide chain by setting up an annular channel, reducing the risk of loosening and chain skipping, and improving operational stability. At the same time, the annular channel can also prevent coal dust and debris from entering the link, extending the maintenance cycle and ensuring that the coal mining machine 1 moves stably, continuously, and efficiently along the guide rail 21. Moreover, the drive method has a simple structure, reliable transmission, and can achieve smooth traction.

[0079] In some embodiments, the body 11 is provided with a fixed base, and the sliding shoe 13 is detachably connected to the fixed base.
