Technical Field
[0001] This utility model relates to the field of track protection technology, and in particular to a safety isolation and protection device for rail transit. Background Technology
[0002] Track safety barriers are key protective devices in rail transit systems used to physically isolate track lines from the external environment. They are applied to both sides of the main line and auxiliary lines on ground-level and elevated sections, serving as an important barrier to ensure train operation safety. They belong to the core branch of rail transit safety isolation and protection devices, and together with platform screen doors and turnout protection devices, they form a layered protection system. Their core function is to prevent pedestrians, animals, and various debris from entering the track area through physical barriers, thus avoiding safety accidents such as train collisions and derailments caused by foreign object interference.
[0003] Track safety barriers primarily achieve their protective function through a structural combination of "metal mesh + steel posts." The mesh is bolted to the posts to form a continuous barrier, thereby preventing pedestrians and animals from directly contacting the tracks and reducing the risk of operational disruptions caused by foreign object intrusion. However, in practice, most barriers use hot-dip galvanized steel wire mesh with limited mesh openings, and the connection strength between the mesh and the posts is limited. Adults can climb over the barriers by stepping on the mesh openings to create support points and by bending the bottom of the posts with external force. Once on the tracks, they not only face the life-threatening danger of being hit by a train but also risk electric shock from touching the high-voltage contact wire. Summary of the Invention
[0004] To overcome the above shortcomings, this utility model provides a rail transit safety isolation and protection device, which aims to improve the problem that most existing isolation fences use hot-dip galvanized steel wire mesh with limited mesh size and the connection strength between the mesh and the column is limited. Adults can climb over the isolation fence by stepping on the mesh to form a support point and bending the bottom of the column with external force. Once on the track, they not only face the danger of being hit by a train, but also the risk of electric shock from touching the high-voltage contact wire.

The inside of the two slots is slidably connected to the same locking plate. Multiple cones are fixedly connected to the front side of the anti-climb plate. Fixing components are provided on the top left and right sides of the locking plate.
[0006] As a further description of the above technical solution: The anti-collision mechanism includes a steel mesh, the outer wall of which is slidably connected between two adjacent mounting slots. The same baffle is installed on the rear side of both fixing frames. Two bolts are threaded to the left and right ends of the rear side of the baffle.

[0011] As a further description of the above technical solution: The grounding assembly includes two grounding posts, the tops of which are fixedly connected to the bottom of the steel mesh, and multiple triangular plates are fixedly connected to the bottom of the outer walls of the two grounding posts.
[0012] As a further description of the above technical solution: Both of the mounting brackets are fixedly connected to the bottom of the brackets, and the top front and rear sides of the two mounting brackets are threaded with anchor bolts.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0016] Reference Figures 1-4 An embodiment of this utility model provides a rail transit safety isolation and protection device, including two fixed frames 1, each fixed frame 1 having an anti-climbing mechanism 3 on its top, the anti-climbing mechanism 3 being used to prevent climbing, each fixed frame 1 having an installation groove 2 between adjacent fixed frames 1, and each installation groove 2 having an anti-collision mechanism 4 between adjacent installation grooves 2, the anti-collision mechanism 4 being used to increase anti-collision performance. The anti-climbing mechanism 3 includes two limiting posts 31. The bottom of the two limiting posts 31 is fixedly connected to the top of the two fixing frames 1 respectively. The outer walls of the two limiting posts 31 are slidably connected to the same anti-climbing plate 32. The middle of the outer wall of the two limiting posts 31 is provided with a slot 33. The inside of the two slots 33 is slidably connected to the same card plate 34. The front side of the anti-climbing plate 32 is fixedly connected to multiple cones 35. The top left and right sides of the card plate 34 are provided with fixing components 37. Specifically, when installing the anti-climbing mechanism 3, the anti-climbing plate 32 is slid downwards along the outer walls of the two limiting posts 31 until it reaches a preset height. The clamping plate 34 is then inserted into the slots 33 of the two limiting posts 31, so that the bottom of the clamping plate 34 fits against the top of the anti-climbing plate 32. Through the cooperation between the limiting posts 31 and the anti-climbing plate 32, the installation direction of the anti-climbing plate 32 is limited, preventing the anti-climbing plate 32 from shifting laterally. Through the cooperation between the slots 33 and the clamping plate 34, the anti-climbing plate 32 is supported, preventing it from sliding downwards along the outer walls of the limiting posts 31, thus initially fixing the position of the anti-climbing plate 32. The fixing components 37 on the top left and right sides of the clamping plate 34 are then operated. Through the cooperation between the fixing components 37 and the clamping plate 34 and the limiting posts 31, the clamping plate 34 is fixed inside the slots 33, further enhancing the installation stability of the anti-climbing plate 32 and completing the assembly of the anti-climbing mechanism 3. When the anti-climbing mechanism 3 is in operation, multiple cones 35 on the front side of the anti-climbing plate 32 form a raised structure. When a person attempts to climb the fixed frame 1, the cones 35 will obstruct the climbing action and prevent the person's hands or feet from making stable contact with the anti-climbing plate 32. Through the cooperation of the cones 35 and the anti-climbing plate 32, the climbing path is cut off, and the climbing effect is achieved, so as to avoid the safety accident caused by the person climbing over the isolation device and entering the track area. When installing the anti-collision mechanism 4, the anti-collision mechanism 4 is embedded in the mounting groove 2 between two adjacent fixed frames 1. Through the cooperation between the mounting groove 2 and the anti-collision mechanism 4, the installation position of the anti-collision mechanism 4 is limited, ensuring that the anti-collision mechanism 4 and the fixed frame 1 form a continuous isolation and protection structure. When an object collides with the isolation device, the anti-collision mechanism 4 directly bears the collision force and absorbs the collision energy through its own structural characteristics, reducing the damage of the collision force to the fixed frame 1 and the anti-climbing mechanism 3. Through the cooperation between the anti-collision mechanism 4 and the fixed frame 1, the anti-collision performance of the entire isolation device is improved, and the service life of the device is extended. When maintaining the anti-climbing mechanism 3, release the fixing component 37 from the fixing plate 34, pull the plate 34 out from the inside of the slot 33, and slide the anti-climbing plate 32 upward along the outer wall of the limiting post 31. The anti-climbing plate 32 and the cone 35 can then be inspected or replaced. Check the smoothness of the outer wall of the limiting post 31, clean the impurities inside the slot 33, and ensure that the anti-climbing plate 32 and the plate 34 can slide smoothly. When maintaining the anti-collision mechanism 4, remove the anti-collision mechanism 4 from the inside of the mounting slot 2.
[0017] Reference Figures 1-5 The anti-collision mechanism 4 includes a steel mesh 41. The outer wall of the steel mesh 41 is slidably connected between two adjacent mounting slots 2. The same baffle 42 is installed on the rear side of both fixing frames 1. Two bolts 43 are threadedly connected to the left and right ends of the rear side of the baffle 42. Two threaded holes 44 are opened on the rear side of both fixing frames 1. A ground insertion component 45 is provided at the bottom of the steel mesh 41. Specifically, when installing the anti-collision mechanism 4, the steel mesh 41 is slidably inserted into the mounting groove 2 between the two adjacent fixed frames 1, so that the steel mesh 41 is completely embedded in the mounting groove 2. The baffle 42 is attached to the rear side of the two fixed frames 1, and the bolt 43 on the rear side of the baffle 42 is aligned with the threaded hole 44 on the rear side of the fixed frame 1. The bolt 43 is rotated and moves inward along the threaded hole 44 until the front end of the bolt 43 is in close contact with the rear side of the steel mesh 41. Through the cooperation of the bolt 43, the threaded hole 44, and the baffle 42, the baffle 42 is fixed to the rear side of the fixed frame 1. At the same time, through the squeezing action of the baffle 42 and the bolt 43, the sliding of the steel mesh 41 in the mounting groove 2 is restricted, preventing the steel mesh 41 from coming out of the mounting groove 2, thus completing the initial fixing of the steel mesh 41. Operate the grounding component 45 at the bottom of the steel mesh 41 and insert the grounding component 45 below the ground at the installation position of the device. Through the cooperation of the grounding component 45 with the ground and the steel mesh 41, the steel mesh 41 is fixed from the bottom, which enhances the connection stability between the steel mesh 41 and the ground, prevents the steel mesh 41 from tilting or shifting when it is hit, and further strengthens the installation firmness of the anti-collision mechanism 4. When an object collides with the isolation device, the steel mesh 41 comes into direct contact with the colliding object. The mesh structure of the steel mesh 41 disperses the collision force, reducing localized force concentration. At the same time, the steel mesh 41 itself has a certain degree of toughness and can undergo slight deformation when subjected to collision force, absorbing some of the collision energy and reducing the impact of the collision on the fixed frame 1 and the anti-climbing mechanism 3. Through the cooperation of the steel mesh 41 and the ground insertion component 45, it is ensured that the steel mesh 41 remains stable during the collision process and does not undergo large-scale displacement, continuously playing a collision buffering role and achieving the effect of increasing collision resistance. When installing the anti-climbing mechanism 3, slide the anti-climbing plate 32 along the outer wall of the limiting post 31 to the preset height, insert the card plate 34 into the slot 33 to support the anti-climbing plate 32, fix the position of the card plate 34 by the fixing component 37, and the cone 35 on the front side of the anti-climbing plate 32 prevents people from climbing and cuts off the climbing path. When maintaining the anti-collision mechanism 4, rotate bolt 2 43 in the reverse direction to release the baffle 42 from the steel mesh 41, pull the steel mesh 41 out of the mounting slot 2, check the structural integrity of the steel mesh 41, and replace any damaged steel mesh 41; check the connection status between the ground insertion component 45 and the ground, and repair any looseness of the ground insertion component 45. When maintaining the anti-climbing mechanism 3, release the fixing component 37, remove the clamping plate 34, and slide the anti-climbing plate 32 for inspection or replacement.
[0018] Reference Figures 1-4 The anti-climbing mechanism 3 also includes multiple glass plates 36. The bottom of each glass plate 36 is fixedly connected to the top front side of the anti-climbing plate 32. The installation angles of the multiple glass plates 36 are different. The fixing component 37 includes two bolts 371. The outer walls of the two bolts 371 pass through the top left and right sides of the card plate 34 respectively. The top rear left and right ends of the anti-climbing plate 32 are provided with threaded holes 372. The outer walls of the two bolts 371 are respectively connected to the internal threads of the two threaded holes 372. The width of the anti-climbing plate 32 is set to 45cm-55cm. The top of the anti-climbing plate 32 is a smooth plane. Specifically, when installing the anti-climbing mechanism 3, the anti-climbing plate 32 is first slid downwards along the outer walls of the two limiting posts 31. The anti-climbing plate 32 is 50cm wide and extends horizontally outwards by 35cm, so that it can cover the top and outer area of the fixing frame 1, expanding the anti-climbing coverage. After the anti-climbing plate 32 moves to the preset height, the clamping plate 34 is inserted along the slots 33 of the two limiting posts 31, so that the bottom of the clamping plate 34 fits against the top of the anti-climbing plate 32. Through the cooperation between the limiting posts 31 and the anti-climbing plate 32, the installation direction of the anti-climbing plate 32 is limited, preventing the anti-climbing plate 32 from shifting laterally. Through the cooperation between the slots 33 and the clamping plate 34, the anti-climbing plate 32 is supported, preventing the anti-climbing plate 32 from sliding downwards along the outer walls of the limiting posts 31. Then, two bolts 371 are inserted through the top left and right sides of the clamping plate 34 respectively. The bolts 371 are rotated so that the outer wall of the bolts 371 is connected to the threaded hole 372 on the rear side of the top of the anti-climbing plate 32. Through the cooperation of the bolts 371, the clamping plate 34 and the threaded hole 372, the clamping plate 34 is fixed to the top of the anti-climbing plate 32, further restricting the movement of the anti-climbing plate 32 and realizing the stable installation of the anti-climbing plate 32. When the anti-climbing mechanism 3 is in operation, multiple cones 35 on the front side of the anti-climbing plate 32 form a raised structure, while multiple glass plates 36 on the front top of it form an irregular smooth contact surface due to different installation angles. When a person attempts to climb, the cones 35 prevent the hands or feet from gripping the plate stably, and the multiple glass plates 36 at different angles further prevent the person from stepping on or using it for leverage. Through the cooperation of the cones 35 and the glass plates 36, the climbing path is cut off, thereby achieving the effect of preventing climbing. When maintaining the anti-climbing mechanism 3, rotate bolt 371 in the reverse direction to disengage it from threaded hole 372, pull out the retaining plate 34 from inside the retaining groove 33, and slide the anti-climbing plate 32 upward along the outer wall of the limiting post 31. This allows for the inspection or replacement of the cone 35 and the glass plate 36. Clean the impurities from the outer wall of the limiting post 31 and the inside of the retaining groove 33 to ensure smooth sliding of the anti-climbing plate 32 and the retaining plate 34. Check the fit between bolt 371 and threaded hole 372, and replace worn bolt 371. This achieves stable installation and efficient anti-climbing of the anti-climbing plate 32, providing reliable protection for rail transit safety isolation and protection devices.
[0019] Reference Figures 3-5 The steel mesh 41 is made of low alloy high strength steel. The adjacent mesh nodes of the steel mesh 41 are connected by spot welding. The grounding assembly 45 includes two grounding posts 451. The tops of the two grounding posts 451 are fixedly connected to the bottom of the steel mesh 41. Multiple triangular plates 452 are fixedly connected to the bottom of the outer wall of the two grounding posts 451. Mounting plates 5 are fixedly connected to the bottom of the two fixing frames 1. Anchor bolts 6 are threadedly connected to the front and rear sides of the top of the two mounting plates 5. Specifically, when installing the mounting bracket 1, the mounting plates 5 at the bottom of the two mounting brackets 1 are attached to the preset mounting surface. The anchor bolts 6 on the front and rear sides of the top of the mounting plate 5 are rotated so that the anchor bolts 6 pass through the mounting plate 5 and connect with the mounting surface. Through the cooperation of the anchor bolts 6 with the mounting plate 5 and the mounting surface, the mounting bracket 1 is fixed on the mounting surface to prevent the mounting bracket 1 from shifting during use and to provide a stable support foundation for the entire device. When installing the steel mesh 41, slide the steel mesh 41 into the outer wall of the mounting groove 2 of the two fixing frames 1, so that the two ground posts 451 at the bottom of the steel mesh 41 are inserted into the ground. Multiple triangular plates 452 at the bottom of the outer wall of the ground posts 451 are inserted into the ground together with the ground posts 451. Through the cooperation of the triangular plates 452 with the ground posts 451 and the ground, the connection strength between the ground posts 451 and the ground is enhanced, preventing the steel mesh 41 from coming off the ground when subjected to external force. Place the baffle 42 against the back side of the two fixing frames 1, and rotate the bolts 43 at the left and right ends of the back side of the baffle 42 so that the bolts 43 are threadedly connected to the threaded holes 44 on the back side of the fixing frame 1. Through the cooperation of the bolts 43 with the baffle 42 and the threaded holes 44, the baffle 42 is fixed to the back side of the fixing frame 1, preventing the steel mesh 41 from coming off the back side of the mounting groove 2, thus completing the installation of the steel mesh 41. When an object collides with the device, the steel mesh 41 directly bears the collision force. Its low-alloy high-strength steel material and mesh welded structure can disperse the collision force and reduce local force concentration. Through the structural characteristics of the steel mesh 41 itself, the collision energy is absorbed, reducing the degree of damage to the device. Through the cooperation of the steel mesh 41 and the baffle 42, it is ensured that the steel mesh 41 remains inside the installation groove 2 after the collision, maintaining the protective function. When maintaining the steel mesh 41, rotate bolt 43 in the reverse direction to disengage it from threaded hole 44, remove baffle 42, and slide the steel mesh 41 outward along the mounting groove 2 to lift the ground post 451 off the ground. Then, the steel mesh 41 can be inspected or replaced. Clean the impurities inside the mounting groove 2 to ensure smooth sliding of the steel mesh 41. Check the fit between the anchor bolts 6 and the mounting plate 5, tighten any loose anchor bolts 6, and ensure the stability of the fixing frame 1. This achieves the anti-collision protection and stable installation of the device, providing a guarantee for the stable operation of the rail transit safety isolation and protection device.
[0020] Working principle: The mounting plates 5 at the bottom of the two fixed frames 1 are attached to the preset mounting surface. The anchor bolts 6 on the front and rear sides of the top of the mounting plate 5 are rotated so that the anchor bolts 6 pass through the mounting plate 5 and connect with the mounting surface. Through the cooperation of the anchor bolts 6 with the mounting plate 5 and the mounting surface, the fixed frame 1 is fixed on the mounting surface, preventing the fixed frame 1 from shifting during use, providing a stable support foundation for the entire device, and ensuring the accuracy and stability of subsequent component installation. After the installation of the fixing frame 1 is completed, the anti-collision mechanism 4 is assembled: the steel mesh 41 (made of low-alloy high-strength steel, with added manganese, silicon, and vanadium, and a total content ≤5%) is slidably inserted along the outer wall of the mounting groove 2 between two adjacent fixing frames 1, so that the steel mesh 41 is completely embedded in the mounting groove 2, while ensuring that the two ground posts 451 at the bottom of the steel mesh 41 are inserted into the ground; multiple triangular plates 452 at the bottom of the outer wall of the ground post 451 are inserted into the ground along with the ground post 451. Through the cooperation of the triangular plates 452 with the ground post 451 and the ground, the connection strength between the ground post 451 and the ground is enhanced, preventing the steel mesh 41 from detaching from the ground when subjected to external forces. The steel mesh 41 is fixed at the bottom. Then, the baffle 42 is attached to the rear side of the two fixing frames 1, so that the second bolt 43 on the rear side of the baffle 42 is aligned with the second threaded hole 44 on the rear side of the fixing frame 1. The second bolt 43 is rotated and moves inward along the second threaded hole 44 until the front end of the second bolt 43 is in close contact with the rear side of the steel mesh 41. Through the cooperation of the second bolt 43, the second threaded hole 44, and the baffle 42, the baffle 42 is fixed to the rear side of the fixing frame 1. At the same time, through the squeezing action of the baffle 42 and the second bolt 43, the sliding of the steel mesh 41 inside the mounting groove 2 is restricted, preventing the steel mesh 41 from falling out of the mounting groove 2. The steel mesh 41 is then securely assembled, ensuring that the anti-collision mechanism 4 and the fixing frame 1 form a continuous isolation and protection structure. After the anti-collision mechanism 4 is assembled, the anti-climb mechanism 3 is installed: the anti-climb plate 32 (with a width of 50cm and extending 35cm outward horizontally relative to the mounting surface, this size can cover the top and outer area of the fixing frame 1, expanding the anti-climb coverage) is slid downward along the outer wall of the two limiting posts 31 until the anti-climb plate 32 moves to the preset height; the locking plate 34 is inserted into the slots 33 of the two limiting posts 31, so that the bottom of the locking plate 34 fits against the top of the anti-climb plate 32; the cooperation between the limiting posts 31 and the anti-climb plate 32 limits the installation direction of the anti-climb plate 32, preventing the anti-climb plate 32 from shifting laterally; the cooperation between the slots 33 and the locking plate 34 supports the anti-climb plate 32. 2. To prevent the anti-climbing plate 32 from sliding downward along the outer wall of the limiting post 31, the position of the anti-climbing plate 32 is initially fixed. Then, two bolts 371 are inserted through the top left and right sides of the clamping plate 34 respectively. The bolts 371 are rotated so that the outer wall of the bolts 371 is threadedly connected to the threaded hole 372 on the rear side of the top of the anti-climbing plate 32. Through the cooperation of the bolts 371, the clamping plate 34, and the threaded hole 372, the clamping plate 34 is fixed to the top of the anti-climbing plate 32, further restricting the movement of the anti-climbing plate 32 and realizing the stable installation of the anti-climbing plate 32. At this time, the multiple cones 35 on the front side of the anti-climbing plate 32 and the multiple glass plates 36 on the front side of the top (with different installation angles) form a complete anti-climbing structure. After all components are installed, the device enters the operational protection phase: When a person attempts to climb the fixed frame 1, multiple cones 35 on the front side of the anti-climb plate 32 form a raised structure, preventing the person's hands or feet from making stable contact with the anti-climb plate 32; simultaneously, multiple glass plates 36 on the top front side of the anti-climb plate 32, due to different installation angles, form irregular smooth contact surfaces, further preventing people from stepping on or using them for leverage; through the cooperation of the cones 35 and the glass plates 36, the climbing path is cut off, achieving the effect of preventing climbing and avoiding personnel from climbing over the isolation device into the track area and causing safety accidents. When an object collides with the isolation device, the steel mesh 41 directly contacts the colliding object, and its... The mesh structure disperses the impact force, reduces localized stress concentration, and the low-alloy high-strength steel material itself has a certain degree of toughness, allowing it to undergo slight deformation when subjected to impact force and absorb some of the impact energy. At the same time, the ground-inserting post 451 and the triangular plate 452 enhance the connection stability between the steel mesh 41 and the ground, ensuring that the steel mesh 41 does not undergo large-scale displacement during the collision and continues to play a collision buffering role. Through the cooperation of the steel mesh 41 and the baffle 42, it is ensured that the steel mesh 41 remains inside the installation groove 2 after the collision, maintaining its protective function, reducing the damage to the fixing frame 1 and the anti-climbing mechanism 3 caused by the collision, improving the collision resistance of the entire isolation device, and extending the service life of the device. After the device has been running for a period of time, post-maintenance is required to ensure continuous and stable operation. When maintaining the anti-climb mechanism 3, rotate bolt 371 in the reverse direction to disengage it from the threaded hole 372, pull the clamping plate 34 out of the slot 33, and slide the anti-climb plate 32 upwards along the outer wall of the limiting post 31. This allows for inspection or replacement of the cone 35 and glass plate 36. Simultaneously, clean the impurities from the outer wall of the limiting post 31 and the inside of the slot 33 to ensure smooth sliding of the anti-climb plate 32 and clamping plate 34. Check the fit between bolt 371 and threaded hole 372, and replace worn bolt 371. When maintaining the anti-collision mechanism 4, rotate bolt 43 in the reverse direction to disengage it from the threaded hole 372. Bolt 43 is disengaged from threaded hole 44, baffle 42 is removed, and steel mesh 41 is slid outward along mounting groove 2 to detach ground post 451 from the ground, allowing for inspection or replacement of steel mesh 41. Impurities inside mounting groove 2 are cleaned to ensure smooth sliding of steel mesh 41. The connection between ground post 451 and the ground is checked, and any loosening is repaired. Simultaneously, the fit between anchor bolt 6 and mounting plate 5 is checked, and any loose anchor bolts are tightened to ensure the stability of mounting frame 1. This achieves a dual effect of preventing climbing and enhancing collision resistance, providing comprehensive protection for the stable operation of rail transit safety isolation and protection devices, and meeting the actual needs of rail transit safety isolation and protection.
