Description

Technical Field

[0001] This invention belongs to the field of mining engineering technology, and in particular relates to a material handling device for roadway support along the goaf. Background Technology

[0002] In coal mine longwall mining, the goaf retention technique is widely used for support operations in return airway roadways. However, during temporary rock-blocking support and the installation of individual props and I-beam supports, traditional transport vehicles cannot enter the work area due to limited space in the advance support area and between the end supports and the roadway walls. Therefore, heavy support materials such as No. 11 I-beams and U29 steel sections are usually transported manually.

[0003] The current manual handling method has the following problems: the handling process is time-consuming and labor-intensive, which seriously affects the construction progress; each handling requires 2-3 people to work together, which requires a large amount of labor; and the handling of heavy materials in narrow spaces is prone to accidents such as bumps and slips, which threaten the personal safety of workers.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This invention provides a device for transporting support materials along a goaf, such as... Figure 1-10As shown, the material handling device for the goaf retaining roadway includes: a vehicle body 1 and a placement plate 2 mounted on the vehicle body 1; a partition plate 3 fixedly mounted on the top of the placement plate 2 for material blocking; a box 4 fixedly mounted on the bottom of the vehicle body 1; a barrier net 5 disposed inside the box 4 for wrapping the support material and preventing it from falling; a hook 6 disposed on the barrier net 5; a hanging ring 7 fixedly mounted on the top of the vehicle body 1 and adapted to the hook 6; and a storage mechanism disposed inside the box 4 for storing the barrier net 5.

[0022] In this embodiment, the vehicle body 1 is shaped like a flatbed cart and can be moved using the lever principle. The support material is placed on the placement plate 2 on the vehicle body 1. The partition 3 at the rear of the vehicle body 1 intercepts the material, preventing it from sliding out due to the tilt of the vehicle body 1 when it is pushed. At the same time, the netting 5 is wrapped around the right side of the vehicle body 1 from the left side to the right side, encasing the material. The hooks 6 on the netting 5 are hung on the matching hanging rings 7 on the top of the vehicle body 1 to fix the netting 5, achieving further protection and wrapping the material to prevent it from falling. When the netting 5 is not in use, it can be stored in the storage mechanism inside the box 4. With the setting of the vehicle body 1, netting 5, and partition 3, heavy support materials can be transported quickly, effectively improving construction efficiency and reducing manual handling, thus reducing labor demand. The partition 3 and netting 5 effectively fix and wrap the material, preventing it from falling, reducing safety hazards during manual handling, and ensuring the personal safety of the workers.

[0023] In a further preferred embodiment of the present invention, the vehicle body 1 is composed of a frame, wheels, outriggers and handles. The wheels and outriggers are both installed at the bottom of the vehicle body 1, and the height of the outriggers is lower than that of the wheels. The handles are fixedly installed on one side of the frame.

[0024] In this embodiment, the vehicle body 1 is equipped with a handle and wheels. Due to the long handle and the considerable distance between it and the wheels, based on the lever principle, the force applied by the worker, under the influence of the longer lever arm, allows for easier movement of the vehicle body 1. Furthermore, the bottom of the vehicle body 1 is equipped with outriggers, which are lower than the wheels. During movement, the wheels provide support by contacting the ground, enabling the vehicle body 1 to move smoothly. When the vehicle body 1 is parked or loading support materials, the outriggers are on the ground, providing stable support and preventing slippage. The long handle and the considerable distance between it and the wheels, utilizing the lever principle, significantly reduce the force required for the worker to push the vehicle body 1, making operation more effortless and reducing worker fatigue. The design of the outriggers being lower than the wheels allows for reasonable switching of support methods during movement and loading / parking. During movement, the wheels provide support to ensure flexibility, while the outriggers provide stable support to prevent slippage during parking or loading, improving the stability of the vehicle body 1 in different states and ensuring the safety and smooth operation of material transportation and loading.

[0025] In a further preferred embodiment of the present invention, a limiting plate 8 is slidably provided on the top of the placement plate 2. The limiting plate 8 is used to limit the position of the support material. A sleeve plate 9 is slidably sleeved on the limiting plate 8. A screw block 10 for fixing the sleeve plate 9 is bolted to one side of the sleeve plate 9.

[0026] In this embodiment, a limiting plate 8 is slidably installed on the top of the placement plate 2. The limiting plate 8 is positioned opposite to the partition plate 3. When it is necessary to limit the support material, the worker can move the limiting plate 8 so that both ends of the support material are tightly attached to the partition plate 3 and the limiting plate 8 respectively, thereby limiting the material in the horizontal direction. At the same time, by loosening the screw block 10, the height of the sleeve plate 9 on the limiting plate 8 can be adjusted. After adjusting to a suitable height, the screw block 10 is tightened to fix the sleeve plate 9, thereby limiting the support material of different heights in the vertical direction. The limiting plate 8 can be used to limit the support material in the horizontal direction. The device moves horizontally according to the dimensions of the support material, and works in conjunction with the partition plate 3 to ensure a tight fit between the two ends of the material, achieving precise horizontal limiting and preventing horizontal displacement of the material during transportation, thus ensuring transportation stability. The height can be adjusted by the sleeve plate 9, and different heights of the sleeve plate 9 can be fixed by the screw block 10 to adapt to support materials of different heights, achieving vertical limiting, expanding the applicability of the device, and improving its versatility. It can effectively limit the height of support materials of any height, ensuring the safety of material transportation.

[0027] In a further preferred embodiment of the present invention, a connecting plate 11 is provided on one side of the partition 3, and a one-way screw 12 is rotatably mounted on the placement plate 2. The one-way screw 12 is threadedly connected to the connecting plate 11, and the one-way screw 12 is used to adjust the height of the connecting plate 11.

[0028] In this embodiment, when the height of the connecting plate 11 needs to be adjusted, the worker rotates the one-way screw 12. Due to the characteristics of the threaded connection, the connecting plate 11 will move up and down along the axis of the one-way screw 12, thereby adjusting the height of the connecting plate 11. By adjusting the height of the connecting plate 11, it can be used in conjunction with components such as the limiting plate 8 to limit the support materials of different heights. The adjustable height of the connecting plate 11 allows the device to flexibly adjust the limiting structure according to the support materials of different heights. Whether it is a shorter or taller support material, the height of the connecting plate 11 can be adjusted to cooperate with the limiting plate 8 to effectively limit the material, enhancing the adaptability of the device to materials of different specifications. Precisely limiting the material of different heights can prevent the material from being damaged or causing safety accidents due to shaking or tipping during transportation, ensuring that the material is stably placed on the handling device, ensuring the safety and reliability of the transportation process, and improving the overall safety of the operation.

[0029] In a further preferred embodiment of the present invention, a guide groove is provided on one side of the partition plate 3, a guide rod 13 is fixedly installed in the guide groove, a guide block 14 is slidably sleeved on the guide rod 13, and one side of the guide block 14 is fixedly connected to the connecting plate 11.

[0030] In this embodiment, when the height of the connecting plate 11 is adjusted by rotating the one-way screw 12, the guide block 14 is slidably sleeved on the guide rod 13 and fixed to the connecting plate 11. During the rising or falling process of the connecting plate 11, the guide block 14 will slide linearly along the guide rod 13 in the guide groove. The cooperation between the guide rod 13 and the guide block 14 provides guidance for the movement of the connecting plate 11, ensuring that the connecting plate 11 can only move up and down in the vertical direction without deviation or shaking. Through the setting of the guide rod 13 and the guide block 14, the connecting plate 11 can maintain a stable straight line during the height adjustment process. The movement trajectory avoids inaccurate positioning due to deviation during adjustment, thus ensuring the accuracy of the height adjustment of the connecting plate 11 and ensuring the limiting effect on support materials of different heights. During the movement of the connecting plate 11, the guide block 14 slides along the guide rod 13, providing additional support and stability for the connecting plate 11, enhancing the stability of the entire limiting structure. Even if bumps or external forces are encountered during transportation, the connecting plate 11 can be kept stably at the set height, further ensuring the reliability of the limiting of support materials and improving the overall structural stability and safety of the device.

[0031] In a further preferred embodiment of the present invention, the storage mechanism includes: a rotating cylinder 15 rotatably disposed within the box body 4, with the netting 5 wrapped around the rotating cylinder 15; a handle 16 rotatably mounted on one side of the box body 4 for driving the rotating cylinder 15 to rotate; a set of guide wheels 41 rotatably mounted within the box body 4 for guiding the netting 5; and an installation mechanism disposed on the rotating shaft of the handle 16 and within the box body 4 for mounting the rotating cylinder 15.

[0032] In this embodiment, a transmission connection is achieved between the mounting mechanism and the rotating drum 15. When the netting 5 needs to be stored, the worker turns the handle 16, and the rotating shaft of the handle 16 drives the rotating drum 15 to rotate through the mounting mechanism. As the rotating drum 15 rotates, the netting 5 wrapped around the rotating drum 15 is gradually rolled up and stored in the box 4. When the netting 5 needs to be used, the handle 16 is turned in the opposite direction, the rotating drum 15 rotates in the opposite direction, and the netting 5 is released from the box 4. The design of the storage mechanism makes the storage and use of the netting 5 extremely convenient. Workers can easily roll up and unroll the netting 5 by simply turning the handle 16, eliminating the need for extensive manual sorting and storage, thus greatly improving work efficiency. Storing the netting 5 inside the box 4 prevents it from being damaged by the external environment when not in use, such as scratches or abrasions, extending its lifespan and reducing operating costs. Storing the netting 5 inside the box 4 when not in use also makes the entire handling device look neater and more organized, facilitating storage and movement in relatively confined and complex environments such as coal mine working faces, while also reducing the netting 5's interference with the surrounding environment and other equipment.

[0033] In a further preferred embodiment of the present invention, the installation mechanism includes: a rectangular sleeve 17 fixedly installed on the rotating shaft of the handle 16; a rectangular block 18 slidably disposed within the rectangular sleeve 17; a round rod 19 fixedly installed on one side of the rectangular block 18; and rectangular seats 20 respectively disposed at the right end of the round rod 19 and within the box body 4, wherein the two rectangular seats 20 are respectively connected to the rectangular rotating shafts at both ends of the rotating cylinder 15.

[0034] In this embodiment, when the handle 16 is rotated, the handle 16 shaft drives the rectangular sleeve 17 to rotate, which in turn drives the rectangular seat 20 to rotate through the rectangular block 18 and the round rod 19, ultimately driving the rotating cylinder 15 to rotate, thus realizing the storage and release of the netting 5. When the netting 5 needs to be replaced, simply slide the round rod 19. The round rod 19 drives the rectangular seat 20 to slide away from the rectangular shaft of the rotating cylinder 15, at which point the rotating cylinder 15 can be taken out for the replacement of the netting 5. Through this structural design of the installation mechanism, when the netting 5 needs to be replaced, the operator can easily disconnect the transmission connection between the rotating cylinder 15 and the handle 16 shaft by sliding the round rod 19, thereby taking out the rotating cylinder 15 for the replacement of the netting 5. The whole replacement process is simple and quick, greatly reducing the difficulty and time cost of replacing the netting 5 and improving the maintenance efficiency of the device. The cooperation between the rectangular sleeve 17, the rectangular block 18, the rectangular seat 20, and the rectangular shaft of the rotating drum 15 ensures stability during transmission, avoids slippage or transmission failure, and ensures that the handle 16 can stably and reliably drive the rotating drum 15 to rotate, thereby enabling the normal storage and release of the net 5 and ensuring the normal operation of the overall function of the device.

[0035] In a further preferred embodiment of the present invention, the housing 4 and the one-way screw 12 are provided with a linkage mechanism for synchronously driving the one-way screw 12 and the rotating drum 15 to rotate. The linkage mechanism includes: two sprockets 21 respectively disposed on the shaft of the frame and the rectangular seat 20 located on one side of the housing 4; a chain 22 sleeved on the two sprockets 21, the chain 22 meshing with the two sprockets 21; two connecting gears 23 respectively disposed at the bottom end of the one-way screw 12 and the bottom of the placement plate 2, the two connecting gears 23 meshing with each other; a bevel gear 24 respectively fixedly installed on the shaft of any one of the connecting gears 23 and the sprocket 21, the two bevel gears 24 meshing with each other; and a protective cover 25 disposed on the frame and the housing 4 for protecting the sprockets 21 and the bevel gears.

[0036] In this embodiment, during the release or retraction of the netting 5, the rotating drum 15 rotates, causing the netting 5 to be released or rolled up. Simultaneously, the rotation of the one-way screw 12 drives the connecting plate 11 to rise or fall. Through the transmission ratio settings and mechanical structure coordination between the sprocket 21, chain 22, connecting gear 23, and bevel gear 24, the rising or falling height of the connecting plate 11 is always adapted to the length of the netting 5 being released. The linkage mechanism cleverly connects the driving of the one-way screw 12 and the rotating drum 15, enabling synchronous movement of the one-way screw 12 and the rotating drum 15 during the release or retraction of the netting 5. This synchronous linkage mechanism simplifies the operation process. Workers do not need to operate the unidirectional screw 12 and the rotating drum 15 separately. They only need to complete the release or storage of the barrier net 5 and the height adjustment of the connecting plate 11 through a single drive action, which greatly improves the operation efficiency. Since the height of the connecting plate 11 is always adapted to the length of the barrier net 5, when transporting support materials of different heights, it can ensure that the connecting plate 11 cooperates with the partition 3 to effectively limit the material. No matter how much length the barrier net 5 is released, the connecting plate 11 can be adjusted to the appropriate height in time, avoiding the shaking or displacement of the material due to height mismatch during transportation. This ensures the stability and safety of the support material transportation and improves the reliability and effectiveness of the limiting structure. Coal mine working faces are complex environments with various unfavorable factors such as coal dust, debris, and water vapor. The protective cover 25 can effectively prevent these external substances from entering the linkage mechanism, avoiding coal dust and debris from adhering to components such as sprocket 21, chain 22, connecting gear 23, and bevel gear 24, which could lead to problems such as poor transmission, accelerated wear, or even jamming. This extends the service life of each component of the linkage mechanism and reduces equipment maintenance costs.

[0037] In a further preferred embodiment of the present invention, a spring 26 is fixedly installed on the top of the inner wall of the box 4, a limiting rod 27 is fixedly installed on the bottom end of the spring 26, two annular notches are opened on the round rod 19, the bottom end of the limiting rod 27 is located in either of the annular notches, and a roller 28 is installed on the bottom end of the limiting rod 27, the roller 28 being in close contact with the annular notch.

[0038] In this embodiment, under normal conditions, the roller 28 at the bottom of the limiting rod 27 is located in the annular notch on the left side of the round rod 19. Through the elastic force of the spring 26, the limiting rod 27 is pressed tightly against the annular notch, thereby limiting the round rod 19, preventing the round rod 19 from sliding at will, and ensuring that the rotating drum 15 is in a stable working position.

[0039] When it is necessary to move the round rod 19 (for example, when replacing the barrier net 5, the transmission connection between the rotating drum 15 and the handle 16 shaft needs to be disconnected), the operator slides the limiting rod 27 upward. At this time, the spring 26 is compressed, and the limiting rod 27 and its bottom roller 28 are both away from the annular notch. The round rod 19 loses its limiting function and can move freely. After the round rod 19 moves to the desired position, the operator releases the limiting rod 27. Under the restoring force of the spring 26, the limiting rod 27 moves downward, causing its bottom roller 28 to engage in another annular notch on the round rod 19, limiting the round rod 19 again and fixing it in the current position. This ensures the stability of the rotating drum 15 installation. Through the cooperation of the limiting rod 27, the spring 26, and the annular notch on the round rod 19, a reliable limiting function is provided for the round rod 19. When the round rod 19 does not need to be moved, the roller 28 at the bottom of the limiting rod 27 is inserted into the annular notch, and the elastic force of the spring 26 is used to ensure the limiting is stable, preventing the round rod 19 from sliding due to external vibration or misoperation, thus ensuring the stability and safety of the device during the transportation of support materials.

[0040] In a further preferred embodiment of the present invention, a limiting sleeve 29 is fixedly installed on one side of the inner wall of the box body 4, the limiting sleeve 29 is slidably connected to the limiting rod 27, and an elastic steel plate 30 is fixedly installed on one side of the inner wall of the box body 4, the elastic steel plate 30 being adapted to the slot on one side of the limiting rod 27.

[0041] In this embodiment, the elastic steel plate 30 has a certain elasticity and is adapted to the slot on one side of the limiting rod 27. Under normal conditions, the elastic steel plate 30 is embedded in the slot of the limiting rod 27, which plays an auxiliary limiting role for the limiting rod 27 and prevents the limiting rod 27 from accidentally disengaging from the annular notch on the round rod 19 under the elastic force of the spring 26 or other external forces. This further enhances the limiting effect of the limiting rod 27 on the round rod 19. When it is necessary to move the round rod 19, the operator slides the limiting rod 27 upward. The limiting rod 27 slides upward in the limiting sleeve 29 and squeezes the elastic steel plate 30 at the same time, causing the elastic steel plate 30 to undergo elastic deformation and disengage from the slot. At this time, the spring 26 is compressed, and the limiting rod 27 and its bottom roller 28 move away from the annular notch. The round rod 19 loses its limiting effect and can move freely. Through the cooperation between the elastic steel plate 30 and the slot of the limiting rod 27, the limiting effect of the limiting rod 27 on the round rod 19 is further enhanced on the basis of the limiting effect of the spring 26.

[0042] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a groove 31 is provided on the top of the placement plate 2, a slide rod 32 is fixedly installed in the groove 31, a slider 33 is slidably sleeved on the slide rod 32, the slider 33 is fixedly connected to the limiting plate 8, and a fixing bolt is threaded on the slider 33.

[0043] In this embodiment, when the position of the limiting plate 8 needs to be adjusted, the operator only needs to loosen the fixing bolts fixed to the slider 33. At this time, the slider 33 can slide freely on the slide rod 32. Since the slider 33 is fixedly connected to the limiting plate 8, the sliding of the slider 33 will drive the limiting plate 8 to move together, thereby realizing the adjustment of the position of the limiting plate 8. After the limiting plate 8 moves to the appropriate position, the operator tightens the fixing bolts. The fixing bolts will be in close contact with the slide rod 32, and the slider 33 will be fixed at the current position of the slide rod 32 by friction, thereby fixing the limiting plate 8 and keeping it stable during subsequent transportation. The structural design of the limiting plate 8 moving by the slider 33 sliding along the slide rod 32 allows the position of the limiting plate 8 to be flexibly adjusted according to the support materials of different specifications and sizes. Whether transporting narrow or wide support materials, the position of the limiting plate 8 can be adjusted to ensure that the limiting plate 8 cooperates with the partition 3 to effectively limit the material, improving the versatility and adaptability of the device.

[0044] In another embodiment of the present invention, a set of L-shaped plates 34 are hinged to one side of the partition plate 3, and a support plate 35 is slidably installed on each set of L-shaped plates 34, and a fastening bolt 36 is threadedly installed on each set of L-shaped plates 34.

[0045] In this embodiment, before transporting the support material, the operator rotates the L-shaped plate 34 around the hinge point to both sides of the partition 3. At this time, the L-shaped structure of the L-shaped plate 34 can cover the gap between the netting 5 and the partition 3. Then, according to the size of the support material or the actual protection requirements, the operator can slide the support plate 35 to adjust the position of the support plate 35 on the L-shaped plate 34 to further expand or optimize the coverage of the gap. After the support plate 35 is adjusted to the appropriate position, the fastening bolt 36 is tightened. The fastening bolt 36 will be in close contact with the support plate 35 or the L-shaped plate 34, and the support plate 35 will be fixed in the current position by friction, thereby completing the coverage of the gap between the netting 5 and the partition 3. By rotating the L-shaped plate 34 to both sides of the partition 3, its L-shaped structure effectively covers the gap between the netting 5 and the partition 3. This design prevents the support material from falling out of the vehicle body through the gaps during transportation, greatly improving the protection of the material, reducing the risk of material loss, and ensuring the safety and integrity of the support material during transportation.

[0046] In another embodiment of the present invention, a rotating rod 37 is rotatably mounted on one side of the partition 3, and a fan-shaped baffle 38 is fixedly mounted on the rotating rod 37. The fan-shaped baffle 38 is rotatably in contact with one side of the L-shaped plate 34. An anti-slip seat 39 is fixedly mounted on one side of the partition 3, and an anti-slip pad 40 is installed inside the anti-slip seat 39. The anti-slip pad 40 is in close contact with the rotating rod 37.

[0047] In this embodiment, when the L-shaped plate 34 needs to cover the gap between the barrier 5 and the partition 3, the operator rotates the L-shaped plate 34 to a suitable position, and then rotates the rotating rod 37, causing the fan-shaped baffle 38 to rotate to a position where it is in close contact with one side of the L-shaped plate 34. At this time, the fan-shaped baffle 38 plays a limiting and supporting role for the L-shaped plate 34, preventing the L-shaped plate 34 from rotating due to vibration or external force during transportation, thereby ensuring that the L-shaped plate 34 stably covers the gap. During the rotation of the rotating rod 37, the anti-slip pad 40 inside the anti-slip seat 39 is in close contact with the rotating rod 37, and the anti-slip pad 40 generates a large frictional force. When the fan-shaped baffle 38 rotates to a suitable position, this frictional force can prevent the rotating rod 37 from rotating arbitrarily, keeping the fan-shaped baffle 38 in its current position and reliably limiting the L-shaped plate 34. The rotating contact design between the fan-shaped baffle 38 and one side of the L-shaped plate 34 allows the fan-shaped baffle 38 to be effectively limited and supported after the rotating rod 37 drives it to the appropriate position. This limiting method prevents the L-shaped plate 34 from rotating unexpectedly due to vehicle bumps or other external forces during transportation, ensuring that the L-shaped plate 34 remains stably positioned in the gap between the netting 5 and the partition 3, thus improving the protective effect on the support material.

[0048] In summary, compared with related technologies, this device, through the setting of a vehicle body, placement plate, partition, barrier net, and various adjustable limiting structures, achieves the advantages of rapid transportation, effective fixation, and protective wrapping of heavy support materials, thereby effectively reducing the labor intensity of workers, improving construction efficiency, and reducing safety hazards.
