Description

Technical Field

[0001] This utility model relates to the field of safety device technology, specifically to an alarm device for workshop personnel who accidentally enter a chain conveyor system. Background Technology

[0002] In modern industrial production, chain conveyors are widely used in various workshops and production lines as key equipment for the automatic transport of materials or products. However, these conveyors pose certain safety hazards during operation, especially when operators accidentally fall into a running chain conveyor due to negligence, misoperation, or other reasons, potentially leading to serious personal injury accidents. Traditional safety measures, such as guardrails and emergency stop buttons, while reducing risks to some extent, still have monitoring blind spots and limited response speed, making it impossible to detect and quickly handle emergencies.

The solution includes a base plate, a frame, the frame including a chain conveyor belt, a primary screening assembly, the primary screening device including a metal detector, a drive motor at the front end of the frame, a magnetic roller at the output shaft end of the motor, a scraper at one end of the collection frame, and an alarm at the rear end of the frame; it also includes a metal detector, an adjusting motor at one end of the upper side of the base plate, a screw at one end of the adjusting motor, a guide frame and a guide frame at the upper side of the base plate, and an alarm at the rear end of the frame.

[0004] Existing devices, including those mentioned above, have gradually revealed shortcomings in the technology with use, mainly in the following aspects:

[0005] Traditional alarm devices mostly rely on physical contact sensors, such as pressure sensors and photoelectric switches. These sensors have limitations in terms of installation location, monitoring range, and flexibility, making it difficult to achieve comprehensive coverage and real-time monitoring of the entire transmission area. They also cannot effectively distinguish between material and personnel triggering the alarm, which can easily lead to false alarms and missed alarms, affecting production efficiency and safety.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] like Figures 1 to 3 As shown, the alarm device for workers accidentally entering the chain conveyor includes the chain conveyor body 1. A sleeve 4 is slidably mounted on the top of the chain conveyor body 1 along the longitudinal, transverse, and vertical directions via a support mechanism 2.

[0029] An alarm 6 is detachably connected to the upper end of the sleeve plate 4 via a positioning mechanism 5, and a video monitoring mechanism 9 is detachably connected to the lower end of the sleeve plate 4.

[0030] The video surveillance unit 9 includes a vertical plate 91 that is detachably connected to the sleeve plate 4, and infrared thermal imaging cameras 90 are horizontally fixed to the opposite side walls of the vertical plate 91.

[0031] A threaded tube 93 is vertically fixed to the lower end of the sleeve plate 4. A short screw 92 is internally threaded into the threaded tube 93. The lower end of the short screw 92 is fixed to the upper end of the vertical plate 91.

[0032] The positioning mechanism 5 includes a mounting tube 50 fixed to the upper end of the sleeve plate 4. A rod 51 is inserted into the mounting tube 50. The upper end of the rod 51 is fixed to the bottom of the alarm 6. A locking rod 52 is slidably inserted on the opposite side wall of the mounting tube 50. A circular groove 53 is opened on the rod 51. The inner ends of the two locking rods 52 abut against the circular groove 53 respectively.

[0033] The outer ends of the two clamps 52 are respectively vertically fixed to columns. The lower ends of the columns are hinged to the first inclined plates 54 that are horizontally swaying. The other ends of the two first inclined plates 54 are hinged to the connecting plate 55. A threaded rod 56 is horizontally threaded on the connecting plate 55. The end of the threaded rod 56 abuts against the outer wall of the mounting tube 50.

[0034] The support mechanism 2 includes a support rail 20 fixed to the side frame of the chain conveyor body 1. A slide block 21 is slidably provided on the support rail along the longitudinal direction. A vertical rod 27 is vertically fixed on the slide block 21. A vertical tube 28 is slidably mounted on the vertical rod 27 along the vertical direction. A horizontal plate 3 is horizontally fixed to the upper end of the vertical tube 28. A sleeve plate 4 is slidably installed on the horizontal plate 3 along the transverse direction.

[0035] A horizontal bar 22 is fixedly connected to the side wall of the slide block 21. A movable tube 23 is slidably mounted on the horizontal bar 22. A movable ring 25 is fixedly connected to the outside of the movable tube 23. A second inclined plate 26 that swings vertically is hinged to the movable ring 25. The upper end of the second inclined plate 26 is hinged to the outer wall of the vertical tube 28.

[0036] The side wall of the sleeve plate 4 is threaded with a first bolt 8 that abuts against the cross plate 3.

[0037] The side wall of the movable tube 23 is threaded with a second bolt 24 that abuts against the crossbar 22.

[0038] A flashing light 7 is fixed to the top of the alarm 6.

[0039] By setting up a horizontal plate 3 to support the sleeve plate 4, moving the sleeve plate 4 will move the alarm 6 and the flashlight 7, and the position of the alarm 6 and the flashlight 7 can be adjusted, which improves its flexibility and makes it easier for users to observe.

[0040] By setting the threaded tube 93, it is easy to connect to the short screw 92, which facilitates the fixed installation of the infrared thermal imaging camera 90 and also facilitates the disassembly of the infrared thermal imaging camera 90. By setting the infrared thermal imaging camera 90, the body heat on the conveyor belt is detected, and it is determined whether someone has fallen onto the conveyor belt. The results are fed back to the external electrical control box, which then controls the alarm 6 to sound an alarm.

[0041] By setting the annular groove 53, it is convenient to engage with the locking rod 52, thereby positioning and installing the insertion rod 51 and the alarm 6, and improving the stability of the alarm 6.

[0042] The vertical pipe 28 moves vertically, which in turn moves the horizontal plate 3, the alarm 6, and the flashlight 7 vertically, thereby adjusting the support height of the alarm 6 and the flashlight 7, and at the same time adjusting the height of the infrared thermal imaging camera 90, so as to better monitor the conveyor belt.

[0043] In use, the movable tube 23 moves the movable ring 25, and the movable ring 25 pushes the vertical tube 28 to move vertically through the second inclined plate 26. The vertical tube 28 moves the horizontal plate 3, the sleeve plate 4, the positioning mechanism 5, the alarm 6 and the flashlight 7 vertically, adjusting the height of the alarm 6 and the flashlight 7. The vertical movement of the horizontal plate 3 also moves the infrared thermal imaging camera 90 vertically, adjusting its height and increasing the monitoring range.

[0044] The working principle of this device is as follows:

[0045] This utility model, by setting a threaded tube, facilitates connection with a short screw, making it easy to fix and install the infrared thermal imaging camera, and also facilitates the disassembly of the infrared thermal imaging camera. By setting the infrared thermal imaging camera, the heat of the human body on the conveyor belt is detected, and it is determined whether someone has fallen onto the conveyor belt. The feedback is sent to the external electrical control box, which then controls the alarm to sound in time, flashes the flashing light to remind relevant personnel, and controls the chain conveyor to stop running.

[0046] This utility model, by setting up a horizontal bar, a movable tube, a second bolt, a movable ring, a second inclined plate, a vertical bar, and a riser, enables the riser to move vertically, thereby driving the horizontal plate, the alarm, and the flashlight to move vertically, thus adjusting the support height of the alarm and the flashlight, and simultaneously adjusting the height of the infrared thermal imaging camera, facilitating better monitoring of the conveyor belt.
