Description

Technical Field

[0001] This invention belongs to the field of mine filling technology, specifically relating to a cloth-hanging device and method for auxiliary operations of mine filling paste. Background Technology

[0002] Currently, during the process of filling mines with paste, it is often necessary to lay isolation cloth to block the paste and prevent leakage, thereby protecting equipment and personnel, and facilitating control of the paste filling range and shape.

[0003] Current technologies mostly involve workers laying isolation fabric while standing on a movable ladder. After laying each section, the ladder needs to be moved a short distance before laying the next section. Because the fabric roll is quite large, it's difficult for workers to keep it moving with them. Therefore, in practice, workers often carry a portion of the fabric to lay short distances first, then overlap and secure the overlaps with wire. Since the working face in mines is long, this process requires repeated manual movement of the ladder, which is time-consuming, labor-intensive, and requires multiple workers, resulting in low efficiency. Furthermore, the overlaps of the fabric have low strength, making it prone to leakage during the filling process, posing safety hazards to equipment and personnel. Therefore, given the problems with the existing manual, segmented laying method, a fabric-laying device is needed that can continuously lay isolation fabric while reducing worker fatigue and improving efficiency.

[0004] To solve the aforementioned problems, an ideal technological solution is needed. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a fabric-laying device and method for auxiliary operations of mine filling paste, which can continuously lay isolation fabric, reduce the labor intensity of workers, and improve work efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a cloth-hanging device for auxiliary operations of mine filling paste, comprising a vehicle body, a cloth bin, and a lifting cloth-hanging device; the cloth bin and the lifting cloth-hanging device are respectively located at the front and rear ends of the vehicle body, the cloth bin continuously provides isolation cloth to the lifting cloth-hanging device, and the vehicle body is equipped with a power supply to provide lifting power for the lifting cloth-hanging device and moving power for the entire cloth-hanging device; the lifting cloth-hanging device is provided with an operating platform, a guide rod height adjustment mechanism, a first guide rod, a second guide rod, and a detachable hook, the first guide rod and the second guide rod are both mounted on the operating platform through the guide rod height adjustment mechanism, and the... The guide rod height adjustment mechanism is used to adjust the vertical height of the first guide rod and the second guide rod. The hook is slidably mounted on the first guide rod and is used to connect the top of the isolation cloth and drive the isolation cloth to slide along the first guide rod. The first guide rod includes a first guide section, a second guide section, and a second bending section. The first guide section and the second guide section are parallel to each other and connected by the second bending section, so that the second guide section is a certain distance away from the vehicle body in the horizontal direction, so that the hook can convey the isolation cloth to the area away from the vehicle body. The second guide rod is located below the first guide rod and is used to support the rest of the isolation cloth to hang down naturally and unfold, so as to complete the laying of the isolation cloth.

[0007] This design incorporates a first guide rod, a second guide rod, and a hook. The hook causes the top of the isolation cloth to slide along the first guide rod, while the remaining portion of the cloth hangs down and unfolds naturally along the second guide rod. This allows the isolation cloth to be laid above the sealing device. Compared to traditional manual installation, this design reduces the labor intensity for workers, eliminating the need for them to move back and forth along the ladder. Furthermore, the cloth-hanging device in this design includes a cloth compartment, providing workers with a continuous supply of isolation cloth. This ensures a continuous installation, avoiding the risk of leakage at the overlaps that occurs during traditional manual installation, further guaranteeing the safety of downhole equipment and personnel.

[0008] Furthermore, both the first guide rod and the second guide rod are arranged horizontally; the first guide rod also includes a first bent section, one end of which is connected to the first guide section, and the other end is connected to the guide rod height adjustment mechanism, for temporarily storing the hook to be used; the second guide rod is a straight rod and is arranged parallel to the lower side of the first guide section; the top of the isolation cloth moves along the first guide rod via the hook, and the rest of the isolation cloth hangs down naturally and unfolds along the second guide rod, so that the isolation cloth forms a 90-degree angle when it moves to the second guide section.

[0009] In this design, the first guide section and the second guide section of the first guide rod are both parallel to the second guide rod, and the second guide rod is located to the side and below the first guide section. When the top of the isolation cloth passes through the first guide section, the second bending section and the second guide section in succession via the hook, it falls off from the tail end of the first guide rod to the rear of the sealing device. The rest of the isolation cloth hangs down naturally along the second guide rod and unfolds, so that the isolation cloth can be laid on the sealing device at a 90-degree angle.

[0010] Furthermore, the turning span between the first guide section and the second guide section is greater than the thickness of the upper telescopic beam of the sealing device.

[0011] In this design, the turning span between the first and second guide sections is set to be greater than the thickness of the telescopic beam on the sealing device. This is to ensure that, during the actual fabric hanging operation, after the top of the isolation fabric moves along the first guide rod via the hook and detaches, the top of the isolation fabric can fall behind the sealing device. Therefore, during continuous laying, the isolation fabric is less likely to slip off from above the sealing device.

[0012] Furthermore, the guide rod height adjustment mechanism includes a lifting screw mounted on the operating table, a vertically arranged guide shaft, and a top plate that slides with the guide shaft. The lifting screw drives the top plate to move along the guide shaft, and the first guide rod and the second guide rod are connected and fixed to the top plate.

[0013] In this design, a guide rod height adjustment mechanism is used to move the first and second guide rods up and down. In actual operation, the working surface is often uneven, and the fabric hanging equipment will undulate during its movement. Therefore, by flexibly adjusting the height of the first and second guide rods through the guide rod height adjustment mechanism, it can be ensured that the heights of the first and second guide rods are always adapted to the height of the sealing device.

[0014] Furthermore, a first roller group is provided on one side of the guide rod height adjustment mechanism, which is placed vertically to clamp the isolation cloth conveyed from the cloth bin. The first roller group rises or falls together with the guide rod height adjustment mechanism.

[0015] In this scheme, a first set of idlers is fixedly installed on one side of the guide rod height adjustment mechanism. This set can clamp the isolation cloth conveyed from the cloth bin, preventing the isolation cloth from spreading out during the feeding process. At the same time, if the isolation cloth spreads out and falls to the ground, it is easily torn by the coal gangue on the roadway floor, which will affect the progress of the isolation cloth laying operation.

[0016] Furthermore, the fabric compartment includes a fabric compartment bracket, a vertically arranged fabric roll, a fabric roll tray fixedly connected to the lower part of the fabric roll, and a bearing located at the bottom of the fabric compartment; the top of the fabric compartment bracket has a notch, and a pin and a pin seat are provided at the notch to restrict the fabric roll located at the notch; one side of the fabric compartment bracket is provided with an upper connecting ear plate and a lower connecting ear plate for connecting the fabric compartment and the vehicle body; the isolation fabric is wound and stored on the fabric roll and placed above the fabric roll tray, and both the fabric roll and the fabric roll tray rotate synchronously with the bearing; a sleeve for protecting the bearing is fixedly connected to the bottom of the fabric roll tray.

[0017] In this solution, the fabric roll and the fabric roll tray are fixedly connected, and both the fabric roll and the fabric roll tray rotate synchronously with the bearing. Since the isolation fabric is wound and stored on the fabric roll, during the process of laying the isolation fabric, the isolation fabric can rotate in the fabric compartment by pulling the isolation fabric, thereby realizing the continuous conveying of the isolation fabric.

[0018] Furthermore, a second set of idlers is vertically arranged inside the fabric compartment for adjusting the feeding direction of the isolation fabric.

[0019] In this design, by installing a second set of idlers inside the fabric bin, the feeding direction of the isolation fabric can be adjusted, facilitating the extension of the isolation fabric from the fabric bin towards the first set of idlers. Simultaneously, the isolation fabric passes through the gaps within the second set of idlers and is conveyed to the first set of idlers. The two sets of idlers also clamp the isolation fabric, thus preventing it from unraveling as it extends from the fabric bin towards the lifting and hanging device, as it is folded and wound on the fabric roll.

[0020] Furthermore, the bottom of the fabric compartment is also equipped with a damping mechanism for adjusting the feeding speed of the isolation fabric. The damping mechanism is located on one side of the sleeve and includes a housing, a rubber block, a spring, and an adjusting bolt. The side of the housing near the sleeve is open, and the rubber block is placed inside the housing. One end of the rubber block extends from the open side of the housing and abuts against the outer wall of the sleeve. The rubber block has a cavity inside for placing the spring. The adjusting bolt is threaded to the side wall opposite the open side of the housing. Screwing in the end of the adjusting bolt compresses the spring to increase the friction between the rubber block and the outer wall of the sleeve, thereby slowing down the feeding speed of the isolation fabric.

[0021] In this solution, a damping mechanism is installed at the bottom of the fabric compartment. By screwing in the adjusting bolt, the spring is compressed, thereby increasing the friction between the rubber block and the sleeve at the bottom of the fabric roll tray. This can slow down the feeding speed of the isolation fabric to a certain extent, reduce the phenomenon of the isolation fabric piling up due to excessive feeding speed, and thus reduce the situation where the isolation fabric, which is folded and wound on the fabric roll shaft, will unravel as it extends from the fabric compartment to the lifting and hanging device.

[0022] Furthermore, the bottom of the vehicle body is equipped with tracks to improve the stability of the fabric hanging equipment.

[0023] This design incorporates tracks at the bottom of the vehicle, increasing the contact area between the fabric-laying vehicle and the ground compared to using tires. Furthermore, tracks offer greater stability in the complex underground terrain, thus ensuring the safety of the workers.

[0024] The present invention also provides a method for applying fabric for auxiliary operations of mine filling paste, wherein the aforementioned fabric application equipment for auxiliary operations of mine filling paste is used, and the specific steps are as follows: S1: The operator stands on the operating platform of the fabric hanging equipment and first lays the first layer of straw mat on top of the sealing device; S2: The operator uses hooks to hold the top of the isolation cloth. With manual pushing, the top of the isolation cloth slides along the first guide rod towards the top and rear of the sealing device. The rest of the isolation cloth hangs down naturally and unfolds along the second guide rod. Through the cooperation of the first and second guide rods, the isolation cloth is laid out at a 90-degree angle above the sealing device. During the laying of the isolation cloth, the height of the first and second guide rods is matched with the height of the sealing device by adjusting the guide rod height adjustment mechanism. When the first hook moves the top of the isolation cloth to the rear of the sealing device, the hook falls off the first guide rod, and then the isolation cloth is fixed behind the sealing device. Subsequently, as the cloth hanging equipment moves forward, the operator only needs to connect the hooks to the isolation cloth in sequence. Under the coordinated guidance of the first and second guide rods, the top of the isolation cloth follows the hooks and slides down behind the sealing device, thus continuously laying the isolation cloth. S3: After the isolation cloth is laid, lay a second layer of straw mat on top of the sealing device; S4: The upper telescopic beam of the sealing device is raised upwards, and the three-layer structure of "straw mat-isolation cloth-straw mat" is placed under the roadway roof. Then, the top of the isolation cloth is fixed to the anchor net on the roadway roof, and the bottom of the isolation cloth is placed under the lower telescopic beam and pressed down with crushed coal or soil.

[0025] This solution utilizes a hanging device to carry workers in a mobile, continuous laying mode of isolation fabric. This not only reduces the labor intensity of workers and improves work efficiency, but also reduces the risk of paste leakage at the overlap of the isolation fabric, which is common in traditional methods, thus improving safety during the operation. During the laying process, hooks move the top of the isolation fabric along the first guide rod, while the remaining part hangs down and unfolds naturally along the second guide rod. As the top of the isolation fabric continuously detaches from the first guide rod and falls behind the sealing device, the laying of the isolation fabric on the sealing device is completed. A layer of straw mat is pre-laid during the laying process. The rough surface of the straw mat increases the friction between it and the isolation fabric, preventing the isolation fabric from slipping off the top of the sealing device and improving laying efficiency. After the isolation fabric is laid, another layer of straw mat is laid on top. When filling with paste later, the second layer of straw mat protects the top plate of the working surface, reducing the impact of the paste on the top plate.

[0026] This invention has outstanding substantive features and significant progress compared to the prior art, specifically: 1. In this invention, a first guide rod, a second guide rod, and a hook are used. The hook drives the top of the isolation cloth to move along the first guide rod and fall behind the sealing device, while the remaining part of the isolation cloth hangs down naturally along the second guide rod and unfolds, thus completing the laying process of the isolation cloth. Compared with the traditional method of manually laying the isolation cloth with a ladder, this invention can reduce the difficulty of the operation for workers, thereby improving work efficiency.

[0027] 2. In this invention, a cloth-hanging device is used to carry workers to continuously lay the isolation cloth, which avoids the leakage of grease at the overlap of the isolation cloth in the traditional cloth-hanging method, thereby improving the safety of equipment and personnel.

[0028] 3. In this invention, a damping mechanism is set at the bottom of the fabric compartment. By screwing in the adjusting bolt, the spring is compressed, thereby increasing the friction between the rubber block and the sleeve at the bottom of the fabric roll tray. This can slow down the feeding speed of the isolation fabric to a certain extent. At the same time, the damping mechanism, together with the first and second idler roller groups, keeps the isolation fabric in a taut state as it extends from the fabric compartment to the hanging device, thereby preventing the folded isolation fabric from unraveling during the feeding process.

[0031] The technical solution of the present invention will be further described in detail below through specific embodiments. Example 1

[0032] like Figure 1 , Figure 2 As shown, this invention provides a fabric-hanging device for auxiliary operations of paste filling, including a vehicle body 1, a fabric bin 2, and a lifting fabric-hanging device 3. The fabric bin 2 and the lifting fabric-hanging device 3 are respectively located on the front and rear sides of the vehicle body 1. The vehicle body 1 is equipped with a power source, which can provide lifting power for the lifting fabric-hanging device 3 and power for the back-and-forth movement of the entire fabric-hanging device. The bottom of the vehicle body 1 adopts the form of tracks 11, which can increase the contact area with the ground compared with traditional wheels, thereby improving the stability of the entire fabric-hanging device during movement.

[0033] The lifting and lowering fabric hanging device 3 includes an operating platform 31, a guide rod height adjustment mechanism 32, a first guide rod 33, a second guide rod 34, and a hook 35. The operating platform 31 is connected to the vehicle body 1 via a worm gear screw structure, and is powered by the power source inside the vehicle body to raise and lower the operating platform 31. The guide rod height adjustment mechanism 32 is located on the side of the operating platform 31 closest to the vehicle body 1 and can rise and fall together with the operating platform 31. The guide rod height adjustment mechanism 32 is connected and fixed to the first guide rod 33 and the second guide rod 34, and the hook 35 is detachably sleeved on the first guide rod 33. In this embodiment, the hook 35 is a ring hook. By sleeved on the body of the first guide rod 33, the tip of the hook hooks the top of the isolation fabric 4 and slides along the first guide rod 33, while the rest of the isolation fabric 4 hangs down naturally and unfolds along the second guide rod 34. The structural characteristics of the first guide rod 33 and the second guide rod 34 are used to complete the laying of the isolation fabric 4. In practical applications, a suitable number of hooks are pre-placed on the first guide rod according to the required length of the isolation cloth. The guide rod height adjustment mechanism 32 can drive the first guide rod 33 and the second guide rod 34 to move vertically up and down, thereby adjusting the height of the first guide rod 33 and the second guide rod 34. This avoids the height of the first guide rod 33 and the second guide rod 34 from being mismatched with the height of the sealing device due to uneven working surface, which would affect the efficiency of cloth hanging operations.

[0034] The isolation cloth 4 is placed vertically in the cloth compartment 2 in a rolled-up and stored form. By pulling the isolation cloth, it is rotated, thereby providing cloth for the lifting and hanging cloth device 3.

[0035] like Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the first guide rod 33 and the second guide rod 34 in the lifting and hanging fabric device 3 are both hollow cylindrical rods arranged horizontally, and the first guide rod 33 is located above the second guide rod 34. The first guide rod 33 includes a first bent section 331, a first guide section 332, a second bent section 333, and a second guide section 334, wherein the first guide section 332 and the second guide section 334 are both straight rods and are parallel to each other and connected by the second bent section 333. One end of the first bent section 331 is connected to the first guide section 332, and the other end is connected to the top plate 322 of the guide rod height adjustment mechanism 32. The first bent section 331 and the first guide section 332 are arranged perpendicularly in the horizontal direction. The first bent section 331 is mainly used to temporarily store the hooks 35 to be used, thereby alleviating the situation where there are not enough hooks to be used pre-placed on the first guide section 332. The second guide rod 34 is a straight rod set on one side of the top plate 322, and is parallel to the lower side of the first guide section 332 to avoid interfering with the hook 35. The hook 35 hooks the top of the isolation cloth 4 and slides sequentially along the first guide section 332, the second bending section 333, and the second guide section 334 of the first guide rod 33, while the rest of the isolation cloth 4 hangs down naturally and unfolds along the second guide rod 34, so that the top of the isolation cloth 4 and the rest are laid on the sealing device at a 90-degree angle.

[0036] Furthermore, the turning span between the first guide section 332 and the second guide section 334 should be greater than the thickness of the upper telescopic beam of the sealing device. In the actual cloth hanging operation, after the top of the isolation cloth 4 moves to the end point through the hook 35 along the first guide rod 33 and falls off, the top of the isolation cloth can fall behind the sealing device. Thus, during the continuous laying process, the isolation cloth 4 is not easy to slip off the top of the sealing device, thereby ensuring the effectiveness of the cloth hanging equipment in the actual operation process of the present invention.

[0037] The guide rod height adjustment mechanism 32 includes a lifting screw 321, a top plate 322, and a sliding shaft 323. Both ends of the top plate 322 are fixedly connected to the first guide rod 33 and the second guide rod 34, respectively. A through hole is vertically opened on one side of the top plate 322 where it connects to the first guide rod 33. The lifting screw 321 drives the top plate 322 to slide up and down along the sliding shaft 323, thereby causing the first guide rod 33 and the second guide rod 34 to move up and down, thus adjusting the vertical height of the first and second guide rods and ensuring coordination with the height of the sealing device during actual fabric hanging. In this embodiment, the lifting screw 321 is hand-cranked, allowing operators to manually crank the lifting screw to adjust the height of the first guide rod 33 and the second guide rod 34.

[0038] Furthermore, a first roller group 324, consisting of two identical rollers arranged side-by-side and tightly pressed together, is vertically fixed on one side of the guide rod height adjustment mechanism 32. This group is used to clamp the isolation cloth 4 conveyed from the cloth bin 2, preventing the folded isolation cloth from unraveling midway and affecting the work progress. At the same time, the first roller group 324 rises or falls together with the guide rod height adjustment mechanism 32, thereby ensuring that the isolation cloth 4 is clamped when it is hung on the hook 35, facilitating the hanging operation for the workers.

[0039] like Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the fabric storage compartment 2 includes a fabric storage compartment bracket 21, a fabric roll 22, a fabric roll tray 23, and a bearing 24. The fabric roll bracket 21 has a U-shaped notch 211 at its top, with a pin 2111 and a pin seat 2112 at the notch 211 to limit large-scale shaking of the fabric roll 22, thus ensuring smooth conveying of the isolation fabric. One side of the fabric roll bracket 21 has an upper connecting ear plate 212 and a lower connecting ear plate 213 for connecting the fabric storage compartment 2 and the vehicle body 1. In actual use, the upper connecting ear plate 212 and the lower connecting ear plate 213 can be hinged to the fabric storage compartment and the vehicle body via pins. The fabric roll 22 is a hollow straight rod with a protrusion 221 at its bottom. The fabric roll 22 is fixed to the fabric roll tray 23 above the protrusion. The fabric roll tray 23 is circular, and its size matches the isolation fabric wound and stored on the fabric roll 22. The bottom surface of the fabric tray 21 is provided with an inner bearing seat 241 and an outer bearing seat 242 to limit the horizontal displacement of the bearing 24. Both the outer side wall of the inner bearing seat 241 and the inner side wall of the outer bearing seat 242 have bosses. The bearing 24 is horizontally placed between the bosses of the inner bearing seat 241 and the outer bearing seat 242. The inner bearing seat 241 is fixedly connected to the fabric roll tray 23 by bolts. The bottom of the fabric roll tray 23 and the boss of the inner bearing seat are sandwiched between the upper and lower sides of the inner ring of the bearing 24. A groove 2411, which matches the protrusion 221, is provided in the center of the inner bearing seat 241. The protrusion 221 is inserted into the groove 2411 to ensure that the fabric roll shaft 22, the fabric roll tray 23, and the inner bearing seat 241 rotate synchronously with the inner ring of the bearing 24. An oil inlet 2412 is provided at the bottom of the groove 2411 for filling the space between the inner bearing seat 241 and the outer bearing seat 242 with lubricating oil. The outer bearing housing 242 has a bearing baffle 243 on its outer side to limit the vertical displacement of the bearing 24. The bearing baffle 243 is connected and fixed to the outer bearing housing 242 by bolts. The bearing baffle 243 and the boss of the outer bearing housing 242 clamp the outer ring of the bearing 24 to keep the bearing position stable. A cylindrical sleeve 231 matching the bearing baffle 243 is fixedly installed at the bottom of the fabric roll tray 23 to protect the various components installed inside the sleeve 231.

[0040] Furthermore, a second roller group 25, consisting of two identical rollers arranged side-by-side and tightly pressed together, is vertically installed inside the fabric storage compartment 2. This group is used to adjust the feeding direction of the isolation fabric 4 inside the compartment 2. When the isolation fabric 4 is pulled out from the fabric roll and passes through the middle gap of the second roller group 25, the two rollers of the second roller group 25 clamp the isolation fabric, preventing the folded isolation fabric 4 from unraveling inside the fabric storage compartment 2. The isolation fabric 4 extends through the gap inside the second roller group 25 towards the first roller group 324, which also clamps the isolation fabric 4. This ensures that the isolation fabric 4 remains clamped throughout the entire conveying process, preventing the folded isolation fabric 4 from unraveling during conveying and affecting the progress of the fabric hanging operation.

[0041] Furthermore, a damping mechanism 26 for adjusting the feeding speed of the isolation cloth 4 is also provided at the bottom of the cloth compartment 2, and the damping mechanism is located on one side of the sleeve 231. The damping mechanism 26 includes a housing 261, a rubber block 262, a spring 263, and an adjusting bolt 264. The housing 261 is open on the side near the sleeve 231, and the rubber block 262 is placed inside the housing. One end of the rubber block extends from the open side of the housing 261 and abuts against the outer wall surface of the sleeve 231. The rubber block 262 has a cavity inside for placing the spring 263. The adjusting bolt 264 is threaded to the side wall opposite the open side of the outer casing 261. When the rod end of the adjusting bolt 264 is screwed in, the spring 263 is compressed, and the spring 263 will push the rubber block 262, thereby increasing the friction between the rubber block 262 and the outer wall of the sleeve 231. To a certain extent, this can slow down the feeding speed of the isolation cloth, reduce the phenomenon of the isolation cloth piling up due to the excessive feeding speed, and thus reduce the situation where the isolation cloth, which is folded and wound on the cloth roll, will unravel as it extends from the cloth compartment to the lifting and hanging cloth device. Example 2

[0042] This invention provides a method for applying fabric to assist in mine filling paste operations, which is applied to the fabric application equipment in Example 1, such as... Figure 12 As shown, the specific steps are as follows: S1: The operator stands on the operating platform of the cloth hanging equipment and first lays the first layer of straw mat on top of the sealing device 5.

[0043] In step S1, a layer of straw mat is first laid on top of the sealing device. The rough surface of the straw mat increases the friction between it and the isolation cloth, so that the isolation cloth is less likely to slip off the top of the sealing device during the laying process, thereby improving the laying efficiency.

[0044] S2: The operator uses hooks to hook the top of the isolation cloth 4. With manual pushing, the top of the isolation cloth 4 slides along the first guide rod to the rear of the top of the sealing device 5. The rest of the isolation cloth 4 hangs down naturally and unfolds along the second guide rod. Through the cooperation of the first and second guide rods, the isolation cloth 4 is laid at a 90-degree angle above the sealing device. During the laying of the isolation cloth 4, the height of the first and second guide rods is matched with the height of the sealing device 5 by adjusting the guide rod height adjustment mechanism. When the first hook moves the top of the isolation cloth 4 to the rear of the sealing device 5, the hook falls off the first guide rod and then the isolation cloth 4 is fixed to the rear of the sealing device 5. Subsequently, during the forward movement of the cloth hanging equipment, the operator only needs to connect the hooks to the isolation cloth 4 in sequence. Under the coordinated guidance of the first and second guide rods, the top of the isolation cloth 4 follows the hooks and slides down to the rear of the sealing device, thus continuously laying the isolation cloth 4.

[0045] In step S2, the isolation cloth 4 is pre-made according to... Figure 13 The folded form shown is wound and stored on the cloth roll. In actual cloth-hanging operations, the vertical height of the fully unfolded isolation cloth is about 6 meters. However, the cloth compartment of the cloth-hanging device in this invention cannot be manufactured according to the actual size of the isolation cloth, which would not only increase the manufacturing difficulty but also make it difficult to transport and install it to the underground working face. Therefore, based on the environmental conditions of the actual working face, the height of the cloth roll is designed to be 1.5 meters. Figure 13 The folding method in this design reduces the vertical height of the isolation cloth from 6 meters to approximately 1.5 meters by folding the middle section. Additionally, to facilitate hanging the isolation cloth on hooks, the top of the cloth extends out a short distance; in this embodiment, the top of the cloth extends 50-100mm.

[0046] S3: After the isolation cloth 4 is laid, lay a second layer of straw mat on top of the sealing device 5.

[0047] In step S3, after the isolation cloth 4 is laid, a second layer of straw mat is laid on top of the sealing device. This is to prevent the impact of the filling paste spraying out during the subsequent filling process from causing damage to the roof of the working face roadway. The straw mat can buffer the impact of the filling paste.

[0048] S4: The upper telescopic beam 51 of the sealing device 5 is raised upward, and the three-layer structure of "straw mat-isolation cloth-straw mat" is placed under the roadway roof. Then, the top of the isolation cloth is fixed to the anchor net on the roadway roof, and the bottom of the isolation cloth is placed under the lower telescopic beam 52 and pressed down with crushed coal or soil.

[0049] In step S4, after the three-layer structure of "straw mat-isolation cloth-straw mat" is laid, the upper telescopic beam 51 of the sealing device 5 rises upward and presses against the top beam 61 of the hydraulic support 6, thereby pressing the top of the isolation cloth 4 tightly. Then, the sealing device 5 and the hydraulic support 6 are supported together under the roof of the working face roadway. To prevent the isolation cloth from slipping, the top of the isolation cloth is connected to the anchor mesh on the roadway roof, thereby further improving the stability of the isolation cloth. The bottom of the isolation cloth is placed under the lower telescopic beam 52 and pressed tightly with some broken coal or soil, thus completing the laying process of the isolation cloth 4. Through the obstruction of the isolation cloth 4, the fine sand in the filling paste will be left on the filling surface, while the moisture in the paste will be discharged through the isolation cloth.

[0050] In summary, this invention, by setting a first guide rod, a second guide rod, and a hook, uses the hook to drive the top of the isolation cloth along the first guide rod and detach it behind the sealing device, while the remaining part of the isolation cloth hangs down naturally along the second guide rod and unfolds, thus completing the laying process of the isolation cloth. Compared with the traditional method of manually laying the isolation cloth with a ladder, this invention can reduce the difficulty of the operation for workers, thereby improving work efficiency. At the same time, this invention uses a cloth hanging device to carry workers to continuously lay the isolation cloth, avoiding the phenomenon of paste leakage at the overlap of the isolation cloth in the traditional cloth hanging method, thereby improving the safety of equipment and personnel. In addition, this invention sets a damping mechanism at the bottom of the cloth bin, and by screwing in the adjusting bolt to compress the spring, thereby increasing the friction between the rubber block and the sleeve at the bottom of the cloth roll tray, which can slow down the feeding speed of the isolation cloth to a certain extent. At the same time, the damping mechanism, together with the first and second roller groups, keeps the isolation cloth in a taut state as it extends from the cloth bin to the cloth hanging device, thereby preventing the folded isolation cloth from unraveling during the feeding process.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
