Description

Technical Field

[0001] This utility model relates to the field of grating technology, and more specifically, to a grating for all-around protection. Background Technology

[0002] In the fields of industrial automation and safety protection, light gratings are widely used as an important safety device at the entrances and exits of machinery, production lines, and various workplaces to prevent people or objects from accidentally entering dangerous areas, thereby avoiding accidents.

[0003] Currently, optical grating systems on the market typically use infrared light or laser as the detection medium. Through the cooperation of the transmitter and receiver, a protective net composed of one or more beams is formed. When the beam is blocked, the system will immediately issue an alarm or stop the equipment from operating, so as to achieve the purpose of safety protection.

[0004] However, these types of gratings typically consist of a series of vertically arranged transmitters and receivers, forming a light curtain with multiple beams. The limited number of transmitters and receivers in these gratings, the inability to add more as needed, and the large, non-adjustable distance between them all limit their coverage and flexibility, hindering comprehensive protection and failing to meet the higher safety requirements of modern industry. Therefore, we propose a grating for comprehensive protection. Utility Model Content

[0005] The purpose of this invention is to provide a grating that provides all-around protection, thereby addressing the deficiencies mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-3 This utility model provides a technical solution: an all-around protective grating, comprising two symmetrical perforated plates 2, each with a perforated plate structure. One perforated plate 2 has multiple transmitters 21 arranged in a matrix, and the other perforated plate 2 has multiple receivers 22 arranged in a matrix. Limiting disks 23 are fixedly installed at the ends of both transmitters 21 and receivers 22. Studs 24 are fixedly installed at the center of the side of each limiting disk 23, passing through through holes in the corresponding perforated plate 2. Threaded knobs 25 are threaded onto the studs 24. The threaded knobs 25 and the limiting disks 23 abut against the left and right sides of the perforated plate 2, facilitating the assembly of the transmitters 21 and receivers 22. Furthermore, the number of transmitters 21 and receivers 22 can be increased as needed, allowing the grating to cover a larger area and achieve all-around monitoring and protection.

[0026] In this embodiment, an anti-slip layer 251 is provided on the annular side of the threaded knob 25. The anti-slip layer 251 can be made by setting anti-slip stripes. The thickness of the threaded knob 25 is between 1.5cm and 2.5cm, so that the thickness of the threaded knob 25 is always consistent, making it easier to tighten the threaded knob 25 with the palm of the hand.

[0027] Specifically, an elastic washer 26 is fitted on the stud 24, and the threaded knob 25 presses the elastic washer 26 onto the mesh plate 2. The elastic washer 26 can prevent the threaded knob 25 from loosening.

[0028] Furthermore, the bottom of the perforated plate 2 is provided with two symmetrical guide rails 1, and the bottom of the perforated plate 2 is fixedly installed with two symmetrical sliders 20. The sliders 20 are slidably connected to the corresponding guide rails 1. The guide rails 1 are provided with grooves 10 arranged along the length of the guide rails 1. The sliders 20 are located in the grooves 10 and are slidably connected to the grooves 10. The cross-sections of both the sliders 20 and the grooves 10 are T-shaped. The size of the sliders 20 is adapted to the size of the grooves 10 to adjust the distance between the transmitter 21 and the receiver 22.

[0029] In addition, a servo motor 11 is fixedly installed at the end of the guide rail 1, a forward lead screw 12 is fixedly installed at the end of the output shaft of the servo motor 11, and a reverse lead screw 13 is fixedly installed at the end of the forward lead screw 12. The forward lead screw 12 and the reverse lead screw 13 pass through the corresponding slider 20 and are threadedly connected to the slider 20. The external threads on the surfaces of the forward lead screw 12 and the reverse lead screw 13 have opposite directions of rotation, which facilitates the operation of the servo motor 11 to adjust the spacing.

[0030] It is worth noting that two symmetrical base plates 14 are fixedly installed between the two guide rails 1, and the base plates 14 are fixedly installed on the external frame.

[0031] Finally, it should be noted that the transmitter 21, receiver 22, external controller and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0032] When using the all-around protective grating of this utility model, according to actual needs, select the corresponding number of transmitters 21 and receivers 22, pass the studs 24 through the corresponding through holes in the mesh plate 2, then put the elastic washers 26 on the studs 24, and then tighten the threaded knobs 25 on the studs 24, so that the threaded knobs 25 and the limiting discs 23 abut against the left and right sides of the mesh plate 2 respectively. In addition, as needed, the servo motor 11 can be connected to an external power source and made to work. When the servo motor 11 works, the output shaft on it rotates, driving the forward lead screw 12 and the reverse lead screw 13 to rotate. The rotation of the forward lead screw 12 and the reverse lead screw 13 drives the slider 20 to move, further realizing the adjustment of the distance between the transmitters 21 and the receivers 22. After the transmitters 21 and the receivers 22 are connected to an external power source and work, the transmitter 21 emits a light beam, and the receiver 22 receives the light beam.
