Description

Technical Field

[0001] The present invention relates to the technical field of emulsion explosive production, and specifically to a protective device for a rotary buckle machine in an emulsion explosive production line. Background Art

[0002] Emulsion explosive is an industrial explosive and belongs to a type of water-containing explosive. It is named after its special emulsion structure. It consists of oxidants, combustibles, emulsifiers and other additives, and has characteristics such as high detonation velocity, strong water resistance and good safety. It is widely used in fields such as mine exploitation, tunnel engineering, underwater blasting, etc.

[0003] For example, the patent disclosed on the Chinese Patent Network with the publication number: CN109229596A and the patent name: A protective device for a rotary buckle machine in an emulsion explosive production line. The protective device includes a fence, a suspension rope and a power source. The circumferential contour of the fence corresponds to and is larger than the outer contour of the rotary buckle machine in the emulsion explosive production line. The fence surrounds the outer periphery of the rotary buckle machine. One end of the suspension rope is connected to the fence and the other end is connected to the power source, and the suspension rope is at the center of gravity of the fence. The power source is fixed on the fixed object opposite to the rotary buckle machine. The power of the power source acts on the fence through the suspension rope, so that the fence makes lifting and lowering movements on the outer periphery of the rotary buckle machine. Without affecting the normal operation of the rotary buckle machine, this invention can excellently protect the outer periphery of the rotary buckle machine according to the operation needs. The whole protective installation and removal operations are convenient, labor-saving and efficient, and have strong practicability.

[0004] However, this structure can only completely block the entire equipment. During the operation of the equipment, the packaging state of the continuous emulsion explosive strip wound on the surface of the equipment is affected by the blockage, and the operator cannot observe the packaging state of the emulsion explosive strip in real time (such as breakage, abnormal winding, etc.), resulting in the inability to stop the machine in time for processing, which may cause production line failures and even safety hazards (such as explosive leakage or mechanical damage);

[0005] Secondly, if the power source (such as a motor, a hydraulic system) fails or the suspension rope breaks, the fence may suddenly fall, damaging the equipment or endangering the safety of personnel. Frequent lifting and lowering of the fence may cause wear of components such as the suspension rope and pulleys, and regular maintenance and replacement are required, increasing the operation and maintenance costs. Moreover, the overall weight of the fence is too high, the assembly method is more cumbersome, and at the same time, the size of the fence is large, and most of the area of the equipment is blocked after the fence is lifted and lowered, increasing the difficulty of daily cleaning, lubrication or fault troubleshooting.

[0006] Therefore, it is necessary to design and transform the protective device for the rotary buckle machine in the emulsion explosive production line. Summary of the Invention

A shielding plate is fixedly connected to the surface of the shaft rod. One side of the shielding plate away from the shaft rod extends to the outside of the protective frame and blocks the traction end of the traction component. A linkage structure is arranged at the top end of the shaft rod, and the linkage structure can utilize the power of the swing of the vertical plate.

[0015] Preferably, the linkage structure includes helical gears fixedly connected to the top end of the shaft rod and the outer side of the vertical plate, and the helical gears mesh with each other.

[0016] Preferably, a limiting rod is fixedly connected to the surface of the protection frame. Sleeve blocks are sleeved on both sides of the surface of the limiting rod.

[0017] Preferably, a elastic frame is sleeved on the surface of the limiting rod. The outer side of the elastic frame contacts the inner side of the sleeve block. A push plate is fixedly connected to the inner side of the shielding plate.

[0018] Preferably, a connecting block is fixedly connected to the bottom of the traction component. A guiding rod is movably connected to the inner side of the connecting block through a pin shaft.

[0019] Preferably, a pressing plate is fixedly connected to the outer side of the shielding plate. A stress roller is installed at the bottom of the guiding rod. The side of the pressing plate away from the shielding plate can extend to the bottom of the stress roller and is slidably connected to the stress roller.

[0020] Preferably, a balance plate is fixedly connected to the outer surface of the transmission motor. Swing rods are movably connected to both sides of the balance plate and the outer ends of the sliding rods through pin shafts. Brake pads are movably connected to the ends of the swing rods away from the balance plate and the sliding rods through pin shafts. The outer surface of the brake pad contacts the surface of the material wheel.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The present invention drives the traction component and the material wheel to rotate through the transmission shaft, and at the same time uses the vertical plate to fix the protection frame to achieve peripheral shielding during equipment operation; the adjustment structure can synchronously control the swinging of multiple vertical plates, adjust the protection range according to production requirements, balance protection and visibility. At the same time, the protection frame is directly connected to the vertical plate, reducing independent driving components, simplifying the structure and reducing energy consumption. Through multi-stage linkage, full-closed protection is achieved during operation, and the traction end is quickly exposed during shutdown, reducing shutdown maintenance time. Moreover, mechanical structures such as helical gears, screws, and cranks reuse the power source, which can reduce energy consumption and complexity.

[0023] 2. The runner of the present invention is fixed to the bearing block through the extension plate. The sliding cooperation between the sliding rod and the sleeve plate converts the vertical lifting into the swinging motion of the vertical plate, realizing the precise adjustment of the position of the protection frame. The separated structure of the bearing block and the sleeve plate is convenient for maintenance and replacement, and improves the service life of the equipment.

[0024] 3. The present invention converts the rotational motion of the driving motor into vertical lifting through the threaded cooperation between the screw rod and the runner. The transmission path is short, the efficiency is high, the power loss is reduced. At the same time, the support frame restricts the lateral offset of the runner, ensuring a stable lifting process and avoiding jamming or vibration.

[0025] 4. The baffle of the present invention is connected to the movable block through the shaft rod, and can be opened and closed synchronously with the swinging of the vertical plate, forming a dynamic occlusion for the traction end, reducing manual intervention. Moreover, when the baffle is closed, it completely covers the traction end, preventing foreign objects from invading or personnel from accidentally touching.

[0026] 5. The present invention transmits the power of the swinging of the vertical plate to the shaft rod through the meshing of bevel gears to drive the baffle to act, without an additional power source, reducing costs. The gear meshing ensures that the swinging angle of the baffle is strictly matched with that of the vertical plate, avoiding protection failure.

[0027] 6. The present invention converts the sliding of the sleeve block into the clamping force on the traction end through the crank and the clamping plate, preventing offset or fracture caused by tension fluctuations during the traction process. When the clamping plate contacts the traction end, it automatically adjusts the clamping force to adapt to the deformation requirements of different traction materials.

[0028] 7. The present invention triggers the movement of the sleeve block by the swinging of the push plate along with the baffle, realizing the automatic association of the clamping action and the protection state, improving the response speed. At the same time, the elastic frame provides the reset elastic force for the sleeve block, ensuring that the clamping plate is released in time when the protection frame is unfolded, avoiding overpressure on the traction end.

[0029] 8. The present invention inserts the guiding rod into the traction end to extend the traction distance and reduce the risk of fracture caused by material rebound. The guiding rod is movably connected through a pin shaft and can swing slightly with the change of the traction tension to keep the traction path stable.

[0030] 9. When the pressing plate presses the stress roller in the present invention, the guiding rod swings upward to dynamically adjust the tension of the traction end, avoiding over-tension or slack of the material. At the same time, the pressing plate is linked with the baffle, and the traction tension adjustment is synchronized with the protection state, without an additional control signal.

[0031] 10. The brake pad of the present invention is connected to the balance plate through the swing rod. While balancing the vibration of the driving motor, it adjusts the rotational speed of the material wheel through friction to prevent overload and slipping. The swing rod adjusts the contact pressure of the brake pad according to the position change of the sliding rod to adapt to the resistance requirements under different rotational speed conditions.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] As Figures 1 to 8 shown, a protective device for a rotary buckle machine in an emulsion explosive production line provided by the present invention includes a transmission shaft 1;

[0043] The drive shaft 1 serves as the power center, and multiple evenly distributed traction components 2 are fixedly connected to its surface. A material wheel 3 is hinged to the top of the traction component 2 through a pin shaft, forming a freely swingable material conveying unit. When the drive shaft 1 rotates, it can synchronously drive the circumferentially arranged traction components 2 and the material wheels 3 to perform continuous rotary motion. To ensure operational safety, a vertical plate 4 sleeved on the pin shaft is configured on the outside of each material wheel 3. After the vertical plate 4 extends towards the outer edge of the material wheel, it forms a rigid connection with the protective frame 5. The overall length design of the protective frame 5 enables it to completely cover the exposed area of the traction component 2, effectively blocking the contact between the rotating components and the external environment. The adjustment structure 6 provided at the top of the device is connected to each vertical plate 4. During operation, the swing angles of all vertical plates can be uniformly adjusted, thereby achieving dynamic adaptation of the protection range and precise control of the operation gap. This integrated design not only ensures the operational stability of the equipment but also improves the human-machine interaction of maintenance operations.

[0044] Reference Figure 3 , The adjustment structure ⑥ includes a bearing block ⑦ provided on the outer side of the top of the drive shaft ①. A runner ⑧ is configured at the top end of the drive shaft ①, and its surface forms a rigid connection with the bearing block ⑦ sleeved on the outside of the drive shaft ① through an extension plate ⑨, constituting a liftable transmission frame. A sleeve plate 32 is provided on the side of the vertical plate 4 close to the material wheel 3. The sleeve plate is sleeved on the slide rod ⑩ on the outside of the bearing block ⑦ in a sliding fit manner, forming a precise guiding structure. When the transmission structure ⑪ at the top drives the runner ⑧ to perform vertical lifting, the extension plate ⑨ drives the bearing block ⑦ to displace synchronously. At this time, the slide rod ⑩ generates relative motion in the sliding cavity of the sleeve plate 32, and through the lever principle, the vertical displacement is converted into the horizontal swing of the sleeve plate 32, and then the vertical plate 4 is linked to achieve angle adjustment. This mechanism realizes precise displacement control through the transmission structure ⑪, and can adjust the protection coverage range of multiple vertical plates 4 in real time during the operation of the equipment, which not only ensures the dynamic shielding effect on the traction component 2 but also ensures the optimization requirements of the operation gap under different working conditions.

[0045] As a technical optimization solution of the present invention, the runner ⑧ is fixed to the bearing block ⑦ through the extension plate ⑨. The sliding fit between the slide rod ⑩ and the sleeve plate 32 converts the vertical lifting into the swinging action of the vertical plate 4, realizing precise adjustment of the position of the protective frame 5. The separated structure of the bearing block ⑦ and the sleeve plate 32 is convenient for maintenance and replacement, and improves the service life of the equipment.

[0046] Reference Figure 4, the transmission structure 11 includes a support frame 12 fixedly connected to the top of the transmission shaft 1. The runner 8 is sleeved on the surface of the support frame 12 and is slidably connected to the support frame 12. A screw rod 13 is movably connected between the support frame 12 and the transmission shaft 1. The runner 8 is sleeved on the surface of the screw rod 13 and is threadedly connected to the screw rod 13. A transmission motor 14 is fixedly connected to the top of the support frame 12. The output end of the transmission motor 14 penetrates through the support frame 12 and is fixedly connected to the top end of the screw rod 13. The transmission motor 14 can drive the screw rod 13 to rotate and use the thread to push the runner 8 to move vertically up and down.

[0047] As a technical optimization scheme of the present invention, the rotational motion of the transmission motor 14 is converted into vertical lifting through the threaded cooperation between the screw rod 13 and the runner 8. The transmission path is short, the efficiency is high, the power loss is reduced. At the same time, the support frame 12 restricts the lateral offset of the runner 8, ensuring a smooth lifting process and avoiding jamming or vibration.

[0048] Reference Figures 7 - 8 , movable blocks 15 are fixedly connected to both sides of the traction member 2. A shaft rod 16 is movably connected to the inside of the movable block 15 through a bearing. A shielding plate 17 is fixedly connected to the surface of the shaft rod 16. One side of the shielding plate 17 away from the shaft rod 16 extends to the outside of the protection frame 5 and shields the traction end of the traction member 2. A linkage structure is provided at the top end of the shaft rod 16, and the linkage structure can utilize the power of the swinging of the vertical plate 4.

[0049] As a technical optimization scheme of the present invention, the shielding plate 17 is connected to the movable block 15 through the shaft rod 16, and can be opened and closed synchronously with the swinging of the vertical plate 4, forming a dynamic shield for the traction end, reducing manual intervention. Moreover, when the shielding plate 17 is closed, it completely covers the traction end, preventing foreign objects from invading or personnel from accidentally touching.

[0050] Reference Figure 7 , the linkage structure includes helical gears 18 fixedly connected to the top end of the shaft rod 16 and the outside of the vertical plate 4, and the helical gears 18 mesh with each other.

[0051] As a technical optimization scheme of the present invention, the power of the swinging of the vertical plate 4 is transmitted to the shaft rod 16 through the meshing of the helical gears 18 to drive the shielding plate 17 to act, without the need for an additional power source, reducing costs. The gear meshing ensures that the swinging angles of the shielding plate 17 and the vertical plate 4 are strictly matched, avoiding protection failure.

[0052] Reference Figure 8, a limiting rod 19 is fixedly connected to the surface of the protective frame 5. Sleeve blocks 20 are sleeved on both sides of the surface of the limiting rod 19. A linear guide rail structure is provided on the mating surface between the limiting rod 19 and the sleeve blocks 20. The top of the sleeve block 20 is movably connected to a crank 21 through a pin shaft. One side of the crank 21 away from the sleeve block 20 is movably connected to a clamping plate 22 through a pin shaft. One side of the clamping plate 22 away from the crank 21 extends to the outside of the traction member 2 and contacts the traction end of the traction member 2.

[0053] As a technical optimization scheme of the present invention, the sliding of the sleeve block 20 is converted into a clamping force on the traction end through the crank 21 and the clamping plate 22, preventing offset or fracture caused by tension fluctuations during the traction process. When the clamping plate 22 contacts the traction end, the clamping force is automatically adjusted to adapt to the deformation requirements of different traction materials.

[0054] Reference Figure 5 , a elastic frame 23 is sleeved on the surface of the limiting rod 19. The outside of the elastic frame 23 contacts the inside of the sleeve block 20. A push plate 24 is fixedly connected to the inside of the shielding plate 17. One side of the push plate 24 away from the shielding plate 17 can contact the outside of the sleeve block 20 after swinging and push the sleeve block 20 to move inward.

[0055] As a technical optimization scheme of the present invention, the movement of the sleeve block 20 is triggered by the swing of the push plate 24 following the shielding plate 17, realizing the automatic association of the clamping action and the protection state, improving the response speed. At the same time, the elastic frame 23 provides a reset elastic force for the sleeve block 20 to ensure that the clamping plate 22 is released in time when the protective frame 5 is unfolded, avoiding overpressure on the traction end.

[0056] Reference Figure 7 , a connecting block 25 is fixedly connected to the bottom of the traction member 2. A guiding rod 26 is movably connected to the inside of the connecting block 25 through a pin shaft. One side of the guiding rod 26 away from the connecting block 25 extends to the bottom of the traction member 2 and is inserted into the traction end of the traction member 2. The guiding rod 26 is used to extend the distance of the traction end of the traction member 2.

[0057] As a technical optimization scheme of the present invention, by inserting the guiding rod 26 into the traction end, the traction distance is extended, reducing the risk of fracture caused by material rebound. The guiding rod 26 is movably connected through a pin shaft and can swing slightly with the change of the traction tension to keep the traction path stable.

[0058] Reference Figure 8 , a pressing plate 27 is fixedly connected to the outside of the shielding plate 17. A stress roller 28 is installed at the bottom of the guiding rod 26. One side of the pressing plate 27 away from the shielding plate 17 can extend to the bottom of the stress roller 28 and is slidably connected to the stress roller 28. When the pressing plate 27 swings inward following the shielding plate 17, it can squeeze the stress roller 28 to make it swing upward with the guiding rod 26.

[0059] As a technical optimization solution of the present invention, when the pressing plate 27 presses the force-bearing roller 28, the guiding rod 26 swings upward to dynamically adjust the tension at the traction end, avoiding over-tension or slack of the material. At the same time, the pressing plate 27 is linked with the shielding plate 17, and the traction tension adjustment is synchronized with the protection state without the need for an additional control signal.

[0060] Reference Figure 6 , a balance plate 29 is fixedly connected to the outer surface of the transmission motor 14. Both sides of the balance plate 29 and the outer ends of the sliding rods 10 are movably connected to swing rods 30 through pins. The ends of the swing rods 30 far from the balance plate 29 and the sliding rods 10 are movably connected to brake pads 31 through pins, and the outer surfaces of the brake pads 31 are in contact with the surface of the material wheel 3.

[0061] As a technical optimization solution of the present invention, the brake pads 31 are connected to the balance plate 29 through the swing rods 30. While balancing the vibration of the transmission motor 14, the rotation speed of the material wheel 3 is adjusted through friction to prevent overload and slipping. The swing rods 30 adjust the contact pressure of the brake pads 31 according to the position change of the sliding rods 10 to adapt to the resistance requirements under different rotation speed conditions.

[0062] Working principle and usage process of the present invention: The transmission shaft 1 serves as the core power source and is driven by an external motor to rotate, driving the traction component 2 fixed on its surface and the material wheel 3 connected by a pin shaft to rotate synchronously. The protective frame 5 is installed outside the material wheel 3 through the vertical plate 4 and is in an unfolded state, covering the outer periphery of the traction component 2. When it is necessary to shield the traction component 2, the drive motor 14 is started, and the drive motor 14 drives the screw 13 to rotate. Since the screw 13 is threadedly connected to the runner 8, the runner 8 moves vertically along the support frame 12. When the runner 8 moves up and down, the extension plate 9 on its surface drives the bearing block 7 to move synchronously, pushing the slide bar 10 in the sleeve plate 32 to slide, forcing the vertical plate 4 to swing around the pin shaft, thereby adjusting the shielding range of the protective frame 5. When the vertical plate 4 swings, the helical gear 18 on its outer side meshes with the helical gear 18 at the top of the shaft rod 16, driving the shaft rod 16 to rotate, driving the shielding plate 17 to swing around the movable block 15, and the shielding plate 17 swings and closes outside the traction component 2 to cover the traction end of the traction component 2. When the shielding plate 17 swings to the closed state, the push plate 24 on its inner side contacts the sleeve block 20 on the limit rod 19, pushing the sleeve block 20 to slide inward. When the sleeve block 20 moves, it drives the clamping plate 22 to move closer to the traction end of the traction component 2 through the crank 21, clamping and fixing the traction end to prevent deviation or loosening. The elastic frame 23 provides a reset elastic force after the sleeve block 20 moves inward to ensure that the clamping plate 22 automatically loosens when the shielding plate 17 unfolds. The connecting block 25 at the bottom of the traction component 2 is movably connected to the guide rod 26 through a pin shaft, and the end of the guide rod 26 is inserted into the traction end to extend the traction path. When the pressure plate 27 swings with the shielding plate 17, its end presses the force-bearing roller 28, forcing the guide rod 26 to swing upward to adjust the tension or position of the traction end to avoid breakage caused by excessive traction force. The balance plate 29 outside the drive motor 14 is connected to the brake pad 31 through the swing rod 30. When the drive motor 14 runs continuously, the swing rod 30 drives the brake pad 31 to contact the surface of the material wheel 3, dynamically adjusting the rotational resistance of the material wheel 3 through friction to prevent overload or slipping.

[0063] In summary: The protective device for the rotary buckle machine in the emulsion explosive production line, based on the coordinated control of the transmission shaft 1 and the adjustment structure 6, through the mechanical transmission method of driving the runner 8 to move up and down by the screw 11, combined with the sliding guidance of the slide bar 10 and the sleeve plate 32, realizes the synchronous swing adjustment of multiple vertical plates 4, can dynamically adjust the coverage range of the protective frame 5 for the traction component 2, and effectively solves the problem that the traditional protective device cannot adapt to the gaps in different working conditions.

[0064] Secondly, an innovative design of helical gear linkage is adopted to directly transfer the swing power of the vertical plate 4 to the shielding plates 13 on both sides of the traction component 2, driving the crank 16 and the clamping plate 19 to act through the contact between the push plate 18 and the sleeve block 17, forming the automatic clamping and pressure adjustment functions of the traction assembly 20, which not only reduces the configuration of independent power sources but also realizes the coordinated control of the protection and traction actions.

[0065] In addition, the cooperative design of the guide rod 21 and the pressing plate 23 can adjust the working angle of the traction end by squeezing the force-bearing roller 24 when the shielding plate 13 swings. Together with the braking system composed of the balance plate 25 and the swing rod 26, the stability of the operation of the material wheel 3 is further enhanced.

[0066] Through the organic combination of mechanical transmission and the elastic reset elastic frame 19, the whole set of devices realizes the adaptive adjustment of the traction assembly 20 and the rapid response under abnormal conditions while ensuring full coverage of the protection function. It greatly reduces the frequency of manual intervention and optimizes the convenience of equipment maintenance. This integrated design not only improves the intrinsic safety level of the high-risk links in the emulsion explosive production line, but also extends the service life of key components through a multi-dimensional dynamic adjustment mechanism, providing a reliable guarantee for continuous production.
