Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a safety locking device for cutting equipment. Background Technology

[0002] Cutting equipment is a tool or machine used to separate materials into specific shapes or sizes. It is widely used in metal processing, construction, manufacturing and other fields. It achieves cutting through physical means. Common types include mechanical cutting, thermal cutting and water jet cutting. Modern cutting equipment often integrates automated control, which can accurately control the cutting speed and precision, improve efficiency and reduce material waste. It is a key piece of equipment for material processing and forming in industrial production.

[0003] Currently, most cutting equipment relies on manual shutdown to avoid danger, making it difficult to respond to sudden hazards in a timely manner. Although some equipment has safety devices, they can only achieve cutting power, and the cutting blade remains in the processing area, which is prone to secondary damage due to inertia or material collision, making it difficult to form a comprehensive safety defense. Therefore, we propose a safety locking device for cutting equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a safety locking device for cutting equipment. This solves the problem that most existing cutting equipment relies on manual shutdown to avoid danger, making it difficult to respond to sudden hazards in a timely manner. Although some equipment has safety devices, they can only achieve cutting power, and the cutting blade remains in the processing area, which is prone to secondary damage due to inertia or material collision, making it difficult to form a comprehensive safety defense.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safety locking device for a cutting equipment, comprising an operating table, a cutting assembly disposed above the operating table, a safety assembly disposed on the surface of the operating table, the safety assembly comprising a limiting sleeve, the limiting sleeve being fixedly connected to the upper surface of the operating table, two limiting sleeves, a support block being slidably connected to the inner wall of the limiting sleeve, a limiting hole being formed on the surface of the limiting sleeve, a protruding rod being fixedly connected to the surface of the support block, the protruding rod sliding against the inner wall of the limiting hole, a control frame being placed on the operating table, an inclined guide hole being formed on the surface of the control frame, one end of the protruding rod being inserted into the guide hole, the cutting assembly comprising a carrier frame, the carrier frame being located above the operating table, the carrier frame being fixedly connected to the upper end of the support block. The frame is fixedly connected to a positioning block, which is fixedly connected to a sliding rod. An adjusting seat is slidably connected to the sliding rod. A mounting plate is fixedly connected to one side of the adjusting seat. A gearbox is fixedly connected to the surface of the mounting plate. A cutting blade is installed at the output end of the gearbox. When the vision probe detects a safety hazard, the control box can immediately cut off the power to the drive motor and servo motor. At the same time, the control frame and pull rod are linked by the telescopic rod to complete the emergency lifting of the cutting blade in a very short time, so that it can quickly leave the processing area and prevent the cutting action from continuing to cause danger from the source. At the same time, the protective components are activated simultaneously. The push plate pushes away the material or obstacle in time, and the baffle forms a protective barrier. Multiple protective measures respond in concert, greatly reducing the probability of accidents.

[0006] Preferably, a drive motor is fixedly connected to the side of the mounting plate near the gearbox, and the drive end of the drive motor is fixedly connected to the input end of the gearbox. The drive motor transmits power to the cutting blade through the gearbox.

[0007] Preferably, the upper surface of the operating table is provided with a through hole, and the cutting blade is adapted to the through hole.

[0008] Preferably, a connecting plate is fixedly connected to the upper surface of the gearbox, and a protective cover is fixedly connected to the end of the connecting plate away from the gearbox. A servo motor is fixedly connected to the surface of the carrier, and a stabilizing sleeve is fixedly connected to the surface of the carrier. A threaded rod is installed inside the stabilizing sleeve through a bearing. The drive end of the servo motor is fixedly connected to the axis of the threaded rod. The safety component squeezes the protruding rod through the inclined guide hole of the control frame. With the guidance of the limiting sleeve and the limiting hole, it ensures that the support block drives the carrier to rise and fall stably, making the safety action of the cutting blade precise and controllable. Even under complex working conditions such as equipment vibration or material displacement, it can still ensure that the cutting component can reliably leave the danger zone. In the protective component, the cooperation of the spring and the pull rope realizes the flexible reset of the baffle and the push plate, which not only ensures the protective effect in the emergency state, but also does not affect the normal operation cycle of the equipment, thus improving the adaptability of the safety mechanism.

[0009] Preferably, a telescopic rod is fixedly connected to the lower surface of the operating table, a control rod is fixedly connected to the driving end of the telescopic rod, a "C"-shaped pull rod is fixedly connected to the driving end of the control rod, and protrusions are fixedly connected to the upper surfaces of the two control frames, with the two ends of the pull rod respectively fixedly connected to the surfaces of the two protrusions.

[0010] Preferably, a support rod is fixedly connected to the upper surface of the carrier, and a vision probe is fixedly connected to the end of the support rod away from the carrier. The vision probe facilitates timely observation of potential safety hazards in the processing area.

[0011] Preferably, a control box is fixedly connected to one side of the carrier frame. The output end of the control box is electrically connected to the input end of the drive motor, the output end of the control box is electrically connected to the input end of the servo motor, and the output end of the control box is electrically connected to the input end of the telescopic rod.

[0012] Preferably, the surface of the operating table is provided with a protective component, which includes a trigger rod fixedly connected to one side of the control frame. A stop block is fixedly connected to one end of the trigger rod, and a collar is rotatably connected to the trigger rod. A pull rope is fixedly connected to the surface of the collar. Two symmetrically arranged guide blocks are fixedly connected to the surface of the operating table. Support rods are slidably connected to the inner walls of the guide blocks. A baffle is fixedly connected to the side of the upper ends of the two support rods that are close to each other. A push plate is fixedly connected to one side of the baffle. A positioning plate is fixedly connected to the lower end of the support rod. A pull frame is fixedly connected to the lower end of the positioning plate. A pull block is rotatably connected to the inner wall of the pull frame. The end of the pull rope away from the collar is fixedly connected to the surface of the pull block. The entire hazard avoidance process does not require manual operation. From the visual probe monitoring the hazard and the control box issuing the command, to the lifting of the cutting component and the activation of the protective component, and then to the automatic reset after the hazard is eliminated, the entire process is fully automated through mechanical linkage and electronic control system. This not only reduces the potential for accident escalation due to delayed human response, but also reduces the risk of contact for operators in emergency situations. It is especially suitable for high-intensity and high-risk cutting operation scenarios.

[0013] Preferably, a spring is fixedly connected to the upper surface of the positioning disk, the spring is sleeved on the support rod, and the upper end of the spring is fixedly connected to the lower surface of the guide block.

[0014] Preferably, a frame is fixedly connected to the lower surface of the operating table, and a stabilizing frame is fixedly connected to the lower surface of the operating table. A limit wheel is rotatably connected to one side of the stabilizing frame, and the pull rope is inserted into the groove of the limit wheel. The linkage of the telescopic rod, the control frame, and the support block realizes the rapid displacement of the cutting component. The cooperation of the trigger rod, the pull rope, and the support rod drives the protective structure to move. The limit wheel, guide block, and other components ensure stable and efficient force transmission, so that the safety device and the cutting equipment form an organic whole. This does not affect the normal cutting efficiency and can form multiple safety defenses when potential hazards occur, thus comprehensively improving the safety performance of the equipment.

[0015] In summary, the technical effects and advantages of this invention are as follows:

[0016] 1. In this invention, when the vision probe detects a safety hazard, the control box can immediately cut off the power to the drive motor and servo motor. At the same time, through the linkage of the telescopic rod with the control frame, pull rod and other components, the cutting blade is lifted urgently in a very short time, so that it can quickly leave the processing area and prevent the cutting action from causing danger from the source. At the same time, the protective components are activated simultaneously, the push plate pushes away the material or obstacle in time, and the baffle forms a protective barrier. Multiple protective measures respond in concert, greatly reducing the probability of accidents.

[0017] 2. In this invention, the safety component uses the inclined guide hole of the control frame to squeeze the protruding rod, and with the guiding effect of the limiting sleeve and the limiting hole, it ensures that the support block drives the carrier frame to rise and fall stably, so that the cutting blade's avoidance action is precise and controllable. Even under complex working conditions such as equipment vibration or material displacement, it can still ensure that the cutting component can reliably leave the danger zone. In the protective component, the cooperation of the spring and the pull rope enables the baffle and the push plate to be flexibly reset, which not only ensures the protective effect in the emergency state, but also does not affect the normal operation cycle of the equipment, thus improving the adaptability of the safety mechanism.

[0018] 3. In this invention, the entire risk avoidance process does not require manual operation. From the visual probe monitoring the hidden danger and the control box issuing instructions, to the lifting of the cutting component and the activation of the protective component, and then to the automatic reset after the hidden danger is eliminated, the entire process is automated through mechanical linkage and electrical control system. This not only reduces the potential for accidents to escalate due to delayed human response, but also reduces the risk of contact for operators in emergency situations. It is especially suitable for high-intensity and high-risk cutting operation scenarios. Attached Figure Description

A control frame 45 is placed on the operating table 1, and an inclined guide hole 46 is formed on the surface of the control frame 45. One end of the protruding rod 49 is inserted into the guide hole 46. The cutting assembly 3 includes a carrier frame 31, which is located above the operating table 1 and fixedly connected to the upper end of the support block 47. A positioning block 3 is fixedly connected to the surface of the carrier frame 31. 2. A sliding rod 33 is fixedly connected to the surface of the positioning block 32. An adjusting seat 37 is slidably connected to the sliding rod 33. A mounting plate 38 is fixedly connected to one side of the adjusting seat 37. A gearbox 311 is fixedly connected to the surface of the mounting plate 38. A cutting blade 312 is installed at the output end of the gearbox 311. When the vision probe 412 detects a safety hazard, the control box 413 can immediately cut off the power of the drive motor 313 and the servo motor 34. At the same time, through the linkage of the telescopic rod 41 with the control frame 45, the pull rod 43 and other components, the cutting blade 312 is lifted urgently in a very short time, so that it quickly leaves the processing area, thus preventing the cutting action from continuing to cause danger from the source. At the same time, the protective component 5 is activated simultaneously. The push plate 514 pushes away materials or obstacles in time, and the baffle 513 forms a protective barrier. Multiple protective measures respond in concert, greatly reducing the probability of accidents.

[0029] Among them, a drive motor 313 is fixedly connected to the side of the mounting plate 38 near the gearbox 311. The drive end of the drive motor 313 is fixedly connected to the input end of the gearbox 311. The drive motor 313 transmits power to the cutting blade 312 through the gearbox 311.

[0030] The upper surface of the operating table 1 is provided with a through hole 314, and the cutting blade 312 is adapted to the through hole 314.

[0031] The gearbox 311 has a connecting plate 39 fixedly connected to its upper surface. A protective cover 310 is fixedly connected to the end of the connecting plate 39 away from the gearbox 311. A servo motor 34 is fixedly connected to the surface of the carrier 31. A stabilizing sleeve 35 is fixedly connected to the surface of the carrier 31. A threaded rod 36 is installed inside the stabilizing sleeve 35 through a bearing. The drive end of the servo motor 34 is fixedly connected to the axis of the threaded rod 36. The safety component 4 squeezes the protruding rod 49 through the inclined guide hole 46 of the control frame 45. With the guidance of the limiting sleeve 48 and the limiting hole 410, the support block 47 drives the carrier 31 to rise and fall stably, making the avoidance action of the cutting blade 312 precise and controllable. Even under complex working conditions such as equipment vibration or material displacement, the cutting component 3 can still reliably escape from the danger zone. In the protective component 5, the cooperation of the spring 511 and the pull rope 54 realizes the flexible reset of the baffle 513 and the push plate 514, which not only ensures the protective effect in the emergency state, but also does not affect the normal operation cycle of the equipment, thus improving the adaptability of the safety mechanism.

[0032] The lower surface of the control panel 1 is fixedly connected to a telescopic rod 41, the drive end of the telescopic rod 41 is fixedly connected to a control rod 42, the drive end of the control rod 42 is fixedly connected to a "C"-shaped pull rod 43, and the upper surfaces of the two control frames 45 are fixedly connected to protrusions 44. The two ends of the pull rod 43 are fixedly connected to the surfaces of the two protrusions 44 respectively.

[0033] Among them, a support rod 411 is fixedly connected to the upper surface of the carrier 31, and a vision probe 412 is fixedly connected to the end of the support rod 411 away from the carrier 31. Through the vision probe 412, it is convenient to observe potential safety hazards in the processing area in a timely manner.

[0034] Among them, a control box 413 is fixedly connected to one side of the carrier 31. The output end of the control box 413 is electrically connected to the input end of the drive motor 313, the output end of the control box 413 is electrically connected to the input end of the servo motor 34, and the output end of the control box 413 is electrically connected to the input end of the telescopic rod 41.

[0035] The operating console 1 is equipped with a protective component 5, which includes a trigger rod 51. The trigger rod 51 is fixedly connected to one side of the control frame 45. A stop block 52 is fixedly connected to one end of the trigger rod 51. A collar 53 is rotatably connected to the trigger rod 51. A pull rope 54 is fixedly connected to the surface of the collar 53. Two symmetrically arranged guide blocks 512 are fixedly connected to the surface of the operating console 1. Support rods 510 are slidably connected to the inner walls of the guide blocks 512. A baffle 513 is fixedly connected to the upper end of the two support rods 510 on the side that is close to each other. A push plate 514 is fixedly connected to one side of the baffle 513. A positioning plate 5 is fixedly connected to the lower end of the support rods 510. 9. A pull frame 57 is fixedly connected to the lower end of the positioning plate 59. A pull block 58 is rotatably connected to the inner wall of the pull frame 57. The end of the pull rope 54 away from the collar 53 is fixedly connected to the surface of the pull block 58. The entire hazard avoidance process does not require manual operation. From the visual probe 412 monitoring the hazard and the control box 413 issuing the command, to the lifting of the cutting component 3 and the activation of the protective component 5, and then to the automatic reset after the hazard is eliminated, the entire process is fully automated through mechanical linkage and electrical control system. This not only reduces the accident expansion that may be caused by the lag in human response, but also reduces the contact risk of operators in emergency situations. It is especially suitable for high-intensity and high-risk cutting operation scenarios.

[0036] Among them, a spring 511 is fixedly connected to the upper surface of the positioning disk 59, the spring 511 is sleeved on the support rod 510, and the upper end of the spring 511 is fixedly connected to the lower surface of the guide block 512.

[0037] The lower surface of the operating platform 1 is fixedly connected to the frame 2, and the lower surface of the operating platform 1 is fixedly connected to the stabilizing frame 56. One side of the stabilizing frame 56 is rotatably connected to the limiting wheel 55. The pull rope 54 is inserted into the groove of the limiting wheel 55. The linkage of the telescopic rod 41, the control frame 45 and the support block 47 realizes the rapid displacement of the cutting component 3. The cooperation of the trigger rod 51, the pull rope 54 and the support rod 510 drives the protective structure to move. The limiting wheel 55, the guide block 512 and other components ensure the stable and efficient transmission of force, so that the safety device and the cutting equipment form an organic whole. It does not affect the normal cutting efficiency, and can form multiple safety defenses when hidden dangers occur, thus comprehensively improving the safety performance of the equipment.

[0038] Working principle of the invention: When the equipment is working, the vision probe 412 monitors the status of the processing area in real time and transmits the information to the control box 413. When a safety hazard is detected, the control box 413 immediately controls the drive motor 313 and the servo motor 34 to cut off the power and cut off the cutting power. At the same time, the telescopic rod 41 is started. The telescopic rod 41 drives the control rod 42 to move the "C"-shaped pull rod 43. The pull rod 43 pulls the two control frames 45 synchronously through the protrusion 44.

[0039] During the displacement of the control frame 45, the inclined guide hole 46 on its surface squeezes the protruding rod 49. The protruding rod 49 slides along the limiting hole 410 on the surface of the limiting sleeve 48, causing the support block 47 to move upward on the inner wall of the limiting sleeve 48. The carrier 31 at the upper end of the support block 47 rises accordingly, causing the cutting blade 312 on the mounting plate 38 to detach from the processing area through the through hole 314 of the operating table 1, thereby realizing the emergency lifting and safety of the cutting assembly 3.

[0040] At the same time, the control frame 45 drives the collar 53 to move via the trigger rod 51. The collar 53 pulls the pull rope 54. After being guided by the limit wheel 55, the pull rope 54 pulls the pull block 58, causing the pull frame 57 to move the positioning plate 59 downward. The support rod 510 slides along the inner wall of the guide block 512, and the spring 511 is compressed. The baffle 513 at the upper end of the support rod 510 and the push plate 514 descend synchronously. The push plate 514 pushes away the materials or obstacles in the processing area, while the baffle 513 forms a protective barrier to prevent the expansion of hidden dangers.

[0041] Once the safety hazard is eliminated, the control box 413 controls the telescopic rod 41 to retract and reset, the control frame 45 moves back with the pull rod 43, the squeezing force of the guide hole 46 on the protruding rod 49 disappears, the carrier frame 31 drives the support block 47 to fall along the limit sleeve 48 under the action of gravity, the cutting blade 312 returns to the working position, at the same time, the trigger rod 51 no longer pulls the pull rope 54, the spring 511 restores its deformation and pushes the positioning plate 59 to move upward, the support rod 510 drives the baffle 513 and the push plate 514 to reset, and the equipment returns to normal working state.

[0042] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
