[0017] Example 1, by Figures 1-2 , Figure 4 , Figure 7The present invention comprises several sets of longitudinal bar outer layers 1, each made of polytetrafluoroethylene (PTFE). These outer layers prevent seawater corrosion of the inner longitudinal bar layer 103, thereby extending the service life of the entire guardrail and conserving resources. Each set of longitudinal bar outer layers 1 has two layers, and each outer layer 1 contains an insulating layer 102 made of fiberglass reinforced plastic. The insulating layer 102 provides insulation, ensuring the safety of the entire guardrail and preventing lightning strikes during rain, thus protecting workers. Each insulating layer 102 contains an inner longitudinal bar layer 103. 3. The inner layer 103 of the guardrail's longitudinal bars is made of alloy material, ensuring the stability of the entire guardrail. Each inner layer 103 of the guardrail's longitudinal bars has a sliding block 306, also made of alloy material. The sliding block 306, in conjunction with the sealing shell 3, can position the outer layer 1 of the longitudinal bar while allowing for fine-tuning, thus adapting to mining platforms with different slopes. Each sliding block 306 has a fixed support flange 302 at its bottom, also made of alloy material. The support flange 302 supports the entire guardrail, and the bottom of each support flange 302 fits tightly against the railing. A vibration damping disc 303, made of fluororubber, is provided. The vibration damping disc 303 dampens vibrations while ensuring the stability of the entire guardrail. Several guardrail crossbars 4, made of alloy material, are provided between the outer layers 1 of each set of longitudinal bars. Each guardrail crossbar 4 is conveniently positioned for protection. Connecting rods 403, also made of alloy material, are provided at both ends of each guardrail crossbar 4. These connecting rods 403 are used to position the connecting head 5. Each connecting rod 403 contains a connecting head 5, also made of alloy material, which is used for positioning the guardrail crossbar 4. Each connecting rod 403 is externally provided with a sealing tube 401, which is made of fluororubber material. The sealing tube 401 can ensure the safety of the connecting rod 403. Each set of longitudinal rods outer layer 1 has two hinge rings 2 on the left end, which are made of alloy material. Each set of longitudinal rods outer layer 1 has two hinge rods 203 on the right end, which are also made of alloy material. The hinge rings 2 and the hinge rods 203 cooperate to make the angle of several guardrails variable, thereby adapting to mining platforms of different shapes and improving the overall usability of the guardrail. All parts of this guardrail exposed to the air are treated with anti-corrosion measures.

[0018] Example 2, based on Example 1, combined with... Figure 3 , Figures 5-6 , Figure 8Each of the longitudinal rod outer layers 1 is provided with a waterproof cap 101 fixed to its top. The waterproof cap 101 is made of polytetrafluoroethylene (PTFE) material and ensures the sealing of the longitudinal rod outer layer 1. Each longitudinal rod outer layer 1 has a positioning hole 104 at its lower end, which facilitates the positioning of the slider 306. The left end of each longitudinal rod outer layer 1 is fixedly connected to the hinge ring 2. The right end of each longitudinal rod outer layer 1 has two hinge plates 201 fixed to its right side. The hinge plates 201 are made of alloy material and are used to position the hinge rod 203. Each hinge plate 201 is fixedly connected to the hinge rod 203 at its bottom. Each hinge plate 201 has a hinge cap 202 fixed to its top. 202 is made of alloy material. The hinge top 202 tapers upwards to prevent seawater corrosion of the hinge ring 2 and the hinge rod 203. Each hinge rod 203 is slidably connected to the hinge ring 2 outside it. Each support flange 302 and each damping plate 303 is provided with several adapter grooves 304. The adapter grooves 304 are used to position the adapter bolts 305. Each adapter groove 304 has an adapter bolt 305 slidably connected inside it. The bottom of each adapter bolt 305 is fastened to a pre-set bolt hole on the mining platform. Each support flange 302 is also fixed with a sealing shell 3 on top. The sealing shell 3 is made of polytetrafluoroethylene material. The sealing shell 3 can prevent seawater corrosion of the hinge ring 2 and the damping plate 303. Block 306, each slider 306 is provided with a plurality of slider positioning holes 307. Each sealing shell 3 is locked to the outer layer 1 of the longitudinal rod, the insulating layer 102, the inner layer 103 of the guardrail longitudinal rod and the slider positioning holes 307 by the connecting bolts 301. The connecting bolts 301, the sealing shell 3, the slider positioning holes 307 and the positioning holes 104 cooperate to lock the supporting flange 302 and the outer layer 1 of the longitudinal rod, thereby ensuring the stability of the entire guardrail and making the entire guardrail detachable for easy storage. Each guardrail crossbar 4 has a connecting flange 402 tightly fitted to both ends by a flange plate. The connecting flange 402 is provided with a plurality of straight slots (not shown in the figure). The straight groove structure on the connecting flange 402 is similar to that of the adapter groove 304, thus allowing it to accommodate flanges of different sizes of the guardrail crossbars 4, and thus adapting to guardrail crossbars 4 with different outer diameters, thereby improving the overall usability of the guardrail. Each connecting flange 402 is fixedly connected to the connecting rod 403 at its outer end. Each connecting rod 403 has a positioning plate 404 fixed to its outer side. The positioning plate 404 is made of alloy material and is used to position the connecting rod 403. A sealing ring 405 is tightly fitted to the outer side of each positioning plate 404. The connecting rod 403 is made of fluororubber material and prevents seawater from entering the inner layer 103 of the guardrail longitudinal bar.Each connector 5 is slidably connected to the inner layer 103 of the guardrail vertical bar, the insulating layer 102, and the through hole on the outer layer 1 of the vertical bar at one end. A spring 501 is fixed inside each connector 5. The spring 501 is elastic, allowing the connector 5 to engage with the inner layer 103 of the guardrail vertical bar when no force is applied. The other end of each spring 501 is fixedly connected to the connecting rod 403. Each connecting rod 403 has a set of sliding grooves 502 for positioning the moving ring 503. Each connector 5 is slidably connected to the sliding grooves 502 via a set of moving strips 504 made of alloy material. Each set of moving strips 504 is fixedly connected to the moving ring 503, also made of alloy material, which facilitates the movement of the connector 5. When using this guardrail, workers place several supporting flanges 302 on the mining platform in sequence, and further fix vibration damping discs 303 to the bottom of each supporting flange 302. Then, workers insert the outer layer 1 of the longitudinal rod into the sealed outer shell 3 in sequence. Next, workers fix the guardrail crossbar 4 and the connecting rod 403 through the connecting flange 402. Then, workers insert the connector 5 into the through hole on the outer layer 1 of the longitudinal rod in sequence. Due to the action of the sliding groove 502, the connector 5 engages with the inner layer 103 of the guardrail longitudinal rod. Finally, workers use the first set of adapter bolts 305 and the adapter groove 304 to tighten the adapter bolts 305 into the bolt holes on the mining platform. At this point, the supporting flanges 302 can fix each set of the outer layer 1 of the longitudinal rod. This ensures the stability of the guardrail crossbar 4. Further, the worker inserts the second set of hinge rods 203 into the first set of hinge rings 2, thus ensuring the stability of the outer layers 1 of the two adjacent sets of longitudinal bars. At this time, the hinge rings 2 and hinge rods 203 can change the angle of the outer layers 1 of the two adjacent sets of longitudinal bars, thereby increasing the usability of the entire guardrail. The worker then locks the support flanges 302 sequentially to ensure the stability of the entire guardrail. Simultaneously, when there is a slope at the outer edge of the mining platform, the worker can lift the outer layers 1 of the longitudinal bars. Furthermore, the worker locks the positioning holes 104 and the slider positioning holes 307 using the connecting bolts 301, thereby locking the slider 306, the sealing shell 3, and the outer layers 1 of the longitudinal bars, thus ensuring the stability of the outer layers 1 of the two adjacent sets of longitudinal bars while maintaining the protective effect.

[0019] The working process of this utility model is as follows: When using this guardrail, workers place several support flanges 302 on the mining platform in sequence, and then fix a vibration damping plate 303 at the bottom of each support flange 302. At this time, workers insert the outer layer 1 of the longitudinal rod into the sealed outer shell 3 in sequence. Then, workers fix the guardrail crossbar 4 and the connecting rod 403 through the connecting flange 402. At this time, workers insert the connector 5 into the through hole on the outer layer 1 of the longitudinal rod in sequence. At this time, due to the action of the sliding groove 502, the connector 5 is engaged with the inner layer 103 of the guardrail longitudinal rod. Then, workers use the first set of adapter bolts 305 and the adapter groove 304 to tighten the adapter bolts 305 with the bolt holes on the mining platform. At this time, due to the action of the support flange 302, each set of longitudinal rods can be secured. The outer layer 1 is fixed to ensure the stability of the guardrail crossbar 4. Further, the worker inserts the second set of hinge rods 203 into the first set of hinge rings 2 to ensure the stability of the outer layers 1 of the two adjacent sets of longitudinal bars. At this time, the hinge rings 2 and hinge rods 203 can change the angle of the outer layers 1 of the two adjacent sets of longitudinal bars, thereby increasing the usability of the entire guardrail. The worker then locks the support flanges 302 sequentially to ensure the stability of the entire guardrail. Simultaneously, when there is a slope at the outer edge of the mining platform, the worker can lift the outer layer 1 of the longitudinal bars. Furthermore, the worker locks the positioning holes 104 and 307 of the sliders using the connecting bolts 301, thereby locking the slider 306, the sealing shell 3, and the outer layer 1 of the longitudinal bars, ensuring both the stability of the two adjacent sets of outer layers 1 and the protective effect.
