Description

Technical Field

[0001] The utility model relates to the field of electronic fences, in particular to an underground electronic fence with high safety. Background Art

[0002] A tunnel boring machine (TBM) is a type of mechanical equipment specifically designed for mining underground coal seams. It uses a rotating cutterhead or chain to cut the coal seam, separating it from the rock layer and loading it onto transportation equipment, such as a mine car or conveyor belt, for ultimate transport to the surface or other processing areas. The tunnel boring machine also has a support function, capable of supporting the mined tunnel during the tunneling process to prevent tunnel collapse. Currently, tunnel boring machines in underground coal mines operate in confined spaces. Due to their large size and the free swinging of the tail conveyor, the area surrounding the machine body is a high-risk area. During daily operation, warnings are set up and guarded by dedicated personnel, and entry is strictly prohibited. However, the use of dedicated personnel for supervision presents security vulnerabilities and occupies personnel, thereby reducing work efficiency. Therefore, a highly secure underground electronic fence is needed to address the above issues. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] Example 1

[0020] See also Figure 1 As shown, a high-security underground electronic fence includes a control box, an audible and visual alarm 1, a positioning receiver and a locator. The control box is connected to the audible and visual alarm 1, the positioning receiver and the tunneling machine respectively. The positioning receiver is connected to the locator at the same time. A mounting bracket 2 is fixedly installed at the rear end of the audible and visual alarm 1. A limit assembly 3 is slidably installed on the mounting bracket 2. The limit assembly 3 consists of a mounting square rod 8, a limit block 9 and an anti-slip baffle 10. The anti-slip baffle 10 and the limit block 9 are fixedly installed on the upper surface of the mounting square rod 8. At the lower ends, a fixing assembly 4 is installed on the mounting bracket 2 and on both sides of the limit assembly 3. The fixing assembly 4 is composed of a mobile base block 11, a fixed base plate 13, a rubber anti-skid pad 14 and a reset spring 15. The fixed base plate 13 is movably connected to the mobile base block 11. The rubber anti-skid pad 14 is fixedly mounted on the outer end of the mobile base block 11, and the reset spring 15 is fixedly mounted on the inner end of the fixed base plate 13. At the same time, the reset spring 15 is fixedly connected to the mobile base block 11. The sound and light alarm 1 is fixed by the mounting bracket 2, the limit assembly 3 and the fixed assembly Component 4 is installed on the tunnel boring machine guardrail 5. During use and installation, the sound and light alarm 1 can be installed on the tunnel boring machine guardrail 5 through the mounting bracket 2, the limit component 3 and the fixing component 4. At the same time, the control box and the positioning receiver are also installed on the tunnel boring machine guardrail 5. The locator is carried by the staff (except for the tunnel boring machine driver, electrician and other necessary personnel). During use, the positioning receiver determines the distance between the staff and the tunnel boring machine based on the locator carried by the staff. When the staff approaches a certain distance from the tunnel boring machine (≤10 meters from the tunnel boring machine), the positioning receiver will transmit a signal to the control box, and the control box will activate the sound and light alarm 1 to alarm, thereby reminding the staff. When the staff gets closer to the tunnel boring machine (≤5 meters from the tunnel boring machine), the control box can directly disconnect the power supply of the tunnel boring machine, thereby stopping the tunnel boring machine from working, thereby fundamentally improving the safety management level of the tunnel boring head and preventing people from accidentally entering the dangerous area. The use of this electronic fence replaces the personnel guarding and managing the limit, thereby improving the unit work efficiency and making the working environment safer.

[0021] Example 2

[0022] See also Figure 2 、 Figure 3 、 Figure 4 As shown, the mounting bracket 2 is composed of a mounting base plate 6 and a mounting connecting plate 7. The mounting connecting plate 7 is fixedly mounted on one end of the mounting base plate 6. The mounting base plate 6 is fixedly mounted on one end of the sound and light alarm 1. A square hole is provided on the mounting connecting plate 7 on the mounting bracket 2. The mounting square rod 8 on the limit assembly 3 is slid up and down and installed in the square hole opened on the mounting connecting plate 7. The anti-slip baffle 10 is located above the mounting connecting plate 7. The limit block 9 is located below the mounting connecting plate 7. The fixed base plate 13 on the fixed assembly 4 is fixedly connected to the mounting base plate 6 on the mounting bracket 2. The mobile base plate 13 on the fixed assembly 4 A guide rail groove 12 is provided on the block 11, and the mobile base block 11 is sleeved on the fixed base plate 13 through the guide rail groove 12. The return spring 15 is fixedly connected to the inner wall of the guide rail groove 12, and the rubber anti-slip pad 14 is against the vertical rod of the tunnel boring machine guardrail 5. When installing the sound and light alarm 1 on the tunnel boring machine guardrail 5, the mounting bracket 2 installed on the sound and light alarm 1 can be first moved close to the tunnel boring machine guardrail 5, and finally the mounting base plate 6 is in contact with the vertical rod of the tunnel boring machine guardrail 5, and at the same time the two fixing components 4 are between the two adjacent vertical rods, and then the limit component 3 can be pushed downward, and the square rod 8 is installed at this time. It will move downward in the square hole opened on the installation connecting plate 7. During this process, the limit block 9 will push the two moving base blocks 11 on the two fixed components 4 outward. At this time, the moving base block 11 will push the rubber anti-skid pad 14 to move toward the vertical rod of the tunnel boring machine guardrail 5, and the return spring 15 will be compressed by the moving base block 11 and the fixed base plate 13. Finally, the rubber anti-skid pad 14 will rest on the vertical rod of the tunnel boring machine guardrail 5, and the limit block 9 will be between the two fixed components 4. At this time, the installation of the sound and light alarm 1 on the tunnel boring machine guardrail 5 is completed; when it is necessary to remove the sound and light alarm 1 from the tunnel boring machine guardrail 5 is removed from the upper part, the limit assembly 3 can be directly pushed upward, so that the limit block 9 is moved out from between the two fixed assemblies 4. At this time, under the elastic force of the reset spring 15, the mobile base block 11 and the rubber anti-slip pad 14 will move inward. When the rubber anti-slip pad 14 is out of contact with the vertical rod of the tunnel boring machine guardrail 5, the fixation of the sound and light alarm 1 and the tunnel boring machine guardrail 5 is released; by providing the mounting bracket 2, the limit assembly 3 and the fixing assembly 4, the sound and light alarm 1 and the tunnel boring machine guardrail 5 can be conveniently disassembled and assembled, thereby ultimately making the installation efficiency of the electronic fence higher.
