Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mechanical protective equipment, and particularly relates to a mechanical dangerous area isolation protective device. BACKGROUND

[0002] In the fields of industrial production, mechanical processing and automation equipment application, there are a large number of dangerous mechanical equipment, such as punch presses, shearing machines, rotating spindles and the like. The operation area of these equipment is usually defined as a mechanical dangerous area, and if a person mistakenly enters or is too close to the area, serious limb injury accidents are likely to occur. Therefore, effectively isolating and protecting the mechanical dangerous area is an important measure to ensure personnel safety.

[0003] At present, existing protection technologies mainly fall into two categories: the first category is fixed physical isolation, such as using metal fences, protective covers and the like to enclose the dangerous area. Although this method can provide basic physical blocking, it lacks flexibility. When equipment maintenance, material loading and unloading or process adjustment are needed, these isolation facilities need to be manually disassembled or moved, which is cumbersome and affects work efficiency, and in frequent operations, it is easy to be overlooked and not reset in time, leaving safety hazards. The second category is warning protection, such as setting warning lines, safety signs or independent sound and light alarms around the dangerous area. This method can remind personnel to pay attention to safety to a certain extent, but it belongs to passive early warning. It cannot actively detect whether a person has really entered the dangerous area, nor can it take any substantial blocking measures when a person ignores the warning or mistakenly enters due to inattention, and its protection effect completely depends on the self-consciousness and alertness of the personnel, and its reliability is insufficient.

[0004] In summary, the mechanical dangerous area protection schemes in the prior art generally have problems such as passive protection, poor flexibility, inability to actively respond to intrusion and incomplete protection. Therefore, there is an urgent need in the field for an intelligent protection device that can sense personnel intrusion in real time and immediately make an active, rapid and effective isolation response to make up for the shortcomings of the prior art and fundamentally improve the safety level of the production environment.

DETAILED DESCRIPTION

[0020] The technical solution of the present application will be described in detail below in combination with the description and specific embodiments of the drawings.

[0021] Embodiment 1 In combination with the drawings Figures 1-8The present invention discloses a mechanical hazard area isolation and protection device, comprising: a mounting frame 1, wherein a controller 11 is fixedly mounted on the top inner wall of the mounting frame 1, and fixing plates 12 are fixedly mounted at the four bottom corners of the mounting frame 1, each fixing plate 12 having fixing holes 13; and a warning mechanism 2, comprising multiple force-bearing components 21 and alarm components 22, both of which are electrically connected to the controller 11. The force-bearing components 21 are evenly distributed around the mounting frame 1 and are used to send a signal to the controller 11 when stepped on. 22 are evenly and fixedly installed on the top sides of the mounting frame 1, and are used to receive signals from the controller 11 and issue alarm prompts; the protective mechanism 3 includes an isolation cover assembly 31 and a drive assembly 32. The isolation cover assembly 31 is fixedly installed inside the mounting frame 1 and is used to isolate the mechanical hazardous area. The drive assembly 32 is fixedly installed on the top of the mounting frame 1 and is connected to the isolation cover assembly 31. The drive assembly 32 is electrically connected to the controller 11 and is used to receive signals from the controller 11 and drive the isolation cover assembly 31 to open or close according to the signals.

[0022] Specifically, when using this device, it is first installed outside the mechanical hazard area, with the mechanical hazard area located inside the isolation enclosure assembly 31. Then, multiple force-bearing components 21 are embedded in the grooves dug in the ground around the perimeter of the device. When an external person steps on a force-bearing component 21, a signal is sent to the controller 11. The controller 11 will immediately send an activation command to the alarm component 22 to make it issue an alarm prompt. The controller 11 will also send an activation command to the drive component 32, causing the drive component 32 to drive the isolation enclosure assembly 31 to close, thereby isolating and sealing off the mechanical hazard area.

[0023] Example 2 Unlike Embodiment 1, in Embodiment 2 of the mechanical hazard area isolation and protection device of the present invention, further explanation is provided for the warning mechanism 2 to facilitate a thorough understanding of its specific structure and principle by those skilled in the art. In this embodiment, the force-bearing component 21 includes: a mounting box 211 and a force-bearing plate 213. The force-bearing plate 213 is slidably fitted inside the mounting box 211. Multiple return springs 216 are fixedly installed at equal intervals between the bottom of the force-bearing plate 213 and the bottom inner wall of the mounting box 211. Multiple force-bearing buttons 217 are fixedly installed at equal intervals on the bottom inner wall of the mounting box 211. All force-bearing buttons 217 are electrically connected to the controller 11. The top of the force-bearing plate 213 penetrates the top of the mounting box 211 and extends above it, and is fixedly connected to a foot pedal 215. Limiting grooves 212 are formed on both sides of the inner wall of the mounting box 211. Travel limiting blocks 214 are fixedly installed on both sides of the force-bearing plate 213, and the travel limiting blocks 214 are slidably connected to the limiting grooves 212. The alarm component 22 includes: a mounting plate 221, which is fixedly mounted on the top side of the outer perimeter wall of the mounting frame 1. An LED warning light 222 and a speaker 223 are fixedly mounted on the front side of the mounting plate 221. Both the LED warning light 222 and the speaker 223 are electrically connected to the controller 11.

[0024] Specifically, the mounting box 211 is pre-embedded in a groove dug in the ground around the hazardous mechanical area, with its upper surface basically flush with the ground, ensuring that personnel can step on it naturally. When a person approaches and steps on the pedal 215, the pedal 215 transmits pressure to the force plate 213 fixedly connected below it. After receiving downward pressure, the force plate 213 begins to slide smoothly downward along the limiting grooves 212 on both sides of the mounting box 211. At this time, the travel limiting blocks 214 fixed on both sides of the force plate 213 move within the limiting grooves 212, precisely limiting the downward travel of the force plate 213 and preventing excessive downward pressure that could cause structural damage. During the downward movement, multiple return springs 216 are evenly compressed at the bottom of the force plate 213, which serve as buffers and energy storage. When the force plate 213 moves down to a specific trigger position, its bottom simultaneously presses multiple force buttons 217 installed on the inner wall of the bottom of the mounting box 211. This multi-point trigger design greatly improves the system's reliability, ensuring that at least one button is triggered even if the foot position deviates slightly. The moment the force button 217 is activated, an electrical signal is immediately generated and transmitted to the central controller 11 via a wire. Upon receiving the trigger signal from the force button 217, the controller 11 immediately sends an activation command to the alarm component 22. The LED warning light 222, fixed to the mounting plate 221, operates in a high-brightness, high-frequency red flashing mode, making it highly visible even in bright daylight or noisy industrial environments. Simultaneously, the speaker 223 integrated on the same mounting plate 221 emits a high-decibel, specific-tune alarm sound, creating a strong visual and auditory deterrent that effectively penetrates ambient noise, immediately alerting the person stepping on the pedal and other nearby personnel that they are in a dangerous warning area. This alarm state continues until the person leaves the foot pedal 215. At this point, the compressed return spring 216 releases its stored elastic potential energy, pushing the force plate 213 and foot pedal 215 upwards, returning them to their initial positions. The force button 217 pops up, disconnecting the signal. After the controller 11 detects the disappearance of the signal, it waits for a preset short delay, such as 1-2 seconds, to prevent false alarms before instructing the LED warning light 222 and the speaker 223 to stop working, and the system returns to standby mode.

[0025] Example 3 Unlike Embodiment 2, in Embodiment 3 of the mechanical hazardous area isolation and protection device of the present invention, further description of the protection mechanism 3 is provided to facilitate a thorough understanding of the specific structure and principle of the protection mechanism 3 by those skilled in the art. In this embodiment, the isolation cover assembly 31 includes: an annular steel plate 311, with multiple connecting rods 313 uniformly fixedly installed around the annular steel plate 311. The ends of the connecting rods 313 away from the annular steel plate 311 are all fixedly connected to the bottom side of the inner wall of the mounting frame 1. An outer fixing cover 314 is fixedly installed on the top of the annular steel plate 311. An annular groove 312 is formed on the top of the annular steel plate 311. An inner isolation cover 315 is fitted inside the outer fixing cover 314. Multiple arc-shaped blocks 318 are uniformly fixedly installed on the bottom of the inner isolation cover 315, and the arc-shaped blocks 318 are slidably connected to the annular groove 312. Multiple openings 319 are evenly spaced on the periphery of the outer fixing cover 314 and the inner isolation cover 315. The top inner ring of the outer fixed cover 314 is fixedly fitted with a bearing 316, and the top of the inner isolation cover 315 is fixedly installed with a rotating shaft 317, which is rotatably connected to the bearing 316. The drive assembly 32 includes: a drive box 321, which is fixedly installed on the top of the mounting frame 1. A driven gear 323 and a main gear 322 are rotatably installed on the bottom inner wall of the drive box 321. The driven gear 323 and the main gear 322 mesh. The top end of the rotating shaft 317 passes through the top wall of the mounting frame 1 and the bottom wall of the drive box 321, and is fixedly connected to the bottom of the driven gear 323. A servo motor 324 is fixedly installed on the top inner wall of the drive box 321. The output end of the servo motor 324 is fixedly connected to the top of the main gear 322. The servo motor 324 is electrically connected to the controller 11. Multiple heat dissipation holes 325 are evenly opened on the side wall of the drive box 321.

[0026] Specifically, the main action of the protective mechanism 3 is executed by the drive assembly 32. When the controller 11 receives the trigger signal from the warning mechanism 2, it synchronously sends an operation command to the servo motor 324 in the drive assembly 32. The servo motor 324 starts, and its output shaft rotates precisely, driving the main gear 322, which is fixedly connected to it, to rotate. The main gear 322 and the driven gear 323 mesh with each other, forming a gear transmission pair that reduces speed and increases torque. The driven gear 323 starts to rotate under the drive. Since its bottom is fixedly connected to the top of the rotating shaft 317 of the isolation cover assembly 31, it transmits the rotational motion to the rotating shaft 317. The rotating shaft 317 passes upward through the top wall of the mounting frame 1 and the bottom wall of the drive box 321, and forms a rotational connection with the fixed outer cover 314 through the bearing 316, ensuring smooth and stable rotation. The bottom of the rotating shaft 317 is fixed to the top of the inner isolation cover 315, so the inner isolation cover 315 rotates together with the rotating shaft 317. Multiple arc-shaped blocks 318 at the bottom of the inner isolation cover 315 are embedded in the annular groove 312 at the top of the annular steel plate 311. These blocks slide along the groove during rotation, providing stable bottom support and rotational guidance for the inner isolation cover 315, preventing it from wobbling. Initially, the openings 319 on the inner isolation cover 315 and the outer fixed cover 314 are aligned, allowing personnel or materials to pass through. When the servo motor 324 receives a closing command, it drives the inner isolation cover 315 to rotate by a specific angle, such as 45 degrees or 90 degrees, depending on the number of openings, so that the openings 319 of the inner and outer covers are completely staggered, forming a continuous, seamless, closed protective cover that physically blocks all paths into the hazardous mechanical area.

[0027] Working principle: When using this device, first install it outside the mechanical hazard area, and place the mechanical hazard area inside the isolation cover assembly 31. Then, embed multiple force-bearing components 21 into the grooves dug in the ground around the perimeter of the device. When an external person steps on the force-bearing component 21, it will send a signal to the controller 11. The controller 11 will immediately send an activation command to the alarm component 22 to make it issue an alarm prompt. The controller 11 will also send an activation command to the drive component 32, causing the drive component 32 to drive the isolation cover assembly 31 to close, thereby isolating and sealing off the mechanical hazard area.

[0028] Example 4 Unlike Embodiment 3, in Embodiment 4, a mechanical hazardous area isolation and protection device of the present invention has multiple heat dissipation holes 325 evenly opened on the side wall of the drive box 321, which can effectively dissipate the heat generated by the servo motor 324 when it is working, ensuring its long-term stability and lifespan.

[0029] Example 5 Unlike Embodiment 4, in Embodiment 5, the mechanical hazard area isolation and protection device of the present invention has a mounting box 211 pre-embedded in a groove dug in the ground around the mechanical hazard area, making its upper surface basically flush with the ground to ensure that personnel can step on it naturally. When a person approaches and steps on the foot pedal 215, the foot pedal 215 transmits pressure to the force plate 213 fixedly connected below it. After receiving downward pressure, the force plate 213 begins to slide smoothly downward along the limiting grooves 212 on both sides of the mounting box 211. At this time, the travel limiting blocks 214 fixed on both sides of the force plate 213 move within the limiting grooves 212, precisely limiting the downward travel of the force plate 213 and preventing excessive downward pressure that could cause structural damage. During the downward movement, multiple return springs 216 are uniformly compressed at the bottom of the force plate 213, which serve as buffers and energy storage. When the force plate 213 moves down to a specific trigger position, its bottom will simultaneously press multiple force buttons 217 installed on the inner wall of the bottom of the mounting box 211. This multi-point trigger design greatly improves the system's reliability, ensuring that at least one button is triggered even if the foot position deviates slightly. The moment the force button 217 is activated, an electrical signal is immediately generated and transmitted to the central controller 11 via a wire. Upon receiving the trigger signal from the force button 217, the controller 11 immediately sends an activation command to the alarm component 22. The LED warning light 222, fixed to the mounting plate 221, operates in a high-brightness, high-frequency red flashing mode, making it highly visible even in bright daylight or noisy industrial environments. Simultaneously, the speaker 223 integrated on the same mounting plate 221 emits a high-decibel, specific-tune alarm sound, creating a strong visual and auditory deterrent that effectively penetrates ambient noise, immediately alerting the person stepping on the pedal and other nearby personnel that they are in a dangerous warning area. This alarm state continues until the person leaves the foot pedal 215. At this point, the compressed return spring 216 releases its stored elastic potential energy, pushing the force plate 213 and foot pedal 215 upwards, returning them to their initial positions. The force button 217 pops up, disconnecting the signal. After the controller 11 detects the disappearance of the signal, it waits for a preset short delay, such as 1-2 seconds, to prevent false alarms before instructing the LED warning light 222 and the speaker 223 to stop working, and the system returns to standby mode.

[0030] Example 6 Unlike Embodiment 5, in Embodiment 6 of the mechanical hazardous area isolation and protection device of the present invention, the main action of the protection mechanism 3 is performed by the drive assembly 32. When the controller 11 receives the trigger signal from the warning mechanism 2, it synchronously sends an operation command to the servo motor 324 in the drive assembly 32. The servo motor 324 starts, and its output shaft rotates precisely, driving the main gear 322, which is fixedly connected to it, to rotate. The main gear 322 and the driven gear 323 mesh with each other, forming a gear transmission pair with speed reduction and torque increase. The driven gear 323 starts to rotate under the drive. Since its bottom is fixedly connected to the top of the rotating shaft 317 of the isolation cover assembly 31, it transmits the rotational motion to the rotating shaft 317. The rotating shaft 317 passes upward through the top wall of the mounting frame 1 and the bottom wall of the drive box 321, and forms a rotational connection with the fixed outer cover 314 through the bearing 316, ensuring smooth and stable rotation. The bottom of the rotating shaft 317 is fixed to the top of the inner isolation cover 315, so the inner isolation cover 315 rotates together with the rotating shaft 317. Multiple arc-shaped blocks 318 at the bottom of the inner isolation cover 315 are embedded in the annular groove 312 at the top of the annular steel plate 311. These blocks slide along the groove during rotation, providing stable bottom support and rotation guidance for the inner isolation cover 315, preventing it from wobbling. Initially, the openings 319 on the inner isolation cover 315 and the outer fixed cover 314 are aligned, allowing personnel or materials to pass through. When the servo motor 324 receives a closing command, it drives the inner isolation cover 315 to rotate by a specific angle, such as 45 degrees or 90 degrees, depending on the number of openings, so that the openings 319 of the inner and outer covers are completely staggered, forming a continuous, seamless, closed protective cover that physically blocks all paths into the hazardous mechanical area. Multiple heat dissipation holes 325 evenly distributed on the side wall of the drive housing 321 effectively dissipate the heat generated by the servo motor 324 during operation, ensuring its long-term stability and lifespan.
