Description

Technical Field

[0001] This application relates to the field of railway auxiliary instrument technology, specifically a railway sensor protection device. Background Technology

[0002] Shear force sensors are installed on train tracks to monitor the weight of the train.

[0003] Chinese utility model patent CN215931058U discloses a protective cover device for a railway weighing shear force sensor. It prevents damage to the sensor from flying debris by installing a protective cover on the outside of the sensor, reducing the impact on sensor measurements. However, the corresponding base is bolted to both sides of the rail. When a train passes, the rail generates significant vibrations, which are transmitted through the base to the bolts and nuts. Over time, the nuts will loosen due to the vibration, moving away from the base, causing gaps between the base and the rail. This leads to displacement of the protective cover, failing to maintain protection for the sensor.

[0004] Therefore, this application provides a railway sensor protection device to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a railway sensor protection device, which aims to solve the problems mentioned in the background art, such as the large vibrations generated by existing railway tracks when trains pass by, which are transmitted to bolts and nuts through the base, and the nuts loosening due to vibration over time, moving away from the base, causing gaps between the base and the rail, causing the protective cover to shift, and failing to maintain protection for the sensor.

[0006] To achieve the above objectives, this application provides the following technical solution: a railway sensor protection device, applied to a railway rail, comprising a first protective cover and a second protective cover symmetrically arranged on both sides of the railway rail for sensor protection, a first connecting frame and a second connecting frame symmetrically arranged on both sides of the railway rail for mounting the first protective cover and the second protective cover, a connecting screw inserted inside the first connecting frame and the second connecting frame for connecting the first connecting frame and the second connecting frame, and a nut sleeved on the outer wall of one end of the connecting screw for restricting the movement of the second connecting frame;

[0007] To prevent the nut from falling off: an anti-detachment component is provided on the side of the second connecting frame away from the rail to prevent the nut from falling off. The anti-detachment component includes a protective block sleeved on one end of the connecting screw, a push plate disposed inside the protective block for contacting the nut, and a push spring disposed between the inner wall of the protective block and the push plate for pushing the push plate. By simultaneously inserting the connecting screw into the interior of the first connecting frame and the second connecting frame, the first connecting frame and the second connecting frame are clamped onto both sides of the rail. Then, by rotating the nut, the second connecting frame is pressed, thereby fixing the first connecting frame and the second connecting frame onto both sides of the rail. Next, the protective block is fitted onto the end of the connecting screw, and the limiting block is pressed, allowing the connecting rod to be inserted into the insertion block, restricting the movement of the protective block. At the same time, the nut will press the push plate, and the push plate will press the push spring. The restoring force of the push spring acts in the opposite direction on the nut, pushing the nut towards the second connecting frame, thereby preventing the nut from moving away from the second connecting frame under long-term vibration. Finally, the protective cover is fixedly connected to the threaded post through the connecting thread, thereby protecting the end of the connecting screw that extends out of the protective block, thus preventing rainwater from eroding the threads of the connecting screw and making the nut difficult to disassemble.

[0008] Preferably, to facilitate the installation of the protective block and the connecting screw: the protective block has a cover groove for inserting the nut at one end facing the second connecting frame; one side of the inner wall of the cover groove and one side of the push plate each have a through hole for inserting the connecting screw; the push spring and the push plate are disposed inside the cover groove. By inserting the connecting screw into the through holes of the protective block and the push plate, the protective block is positioned on one side of the second connecting frame.

[0009] Preferably, to facilitate the fixed installation of the protective block and the second connecting frame: the end of the connecting rod is provided with a connector for restricting the movement of the connecting rod; a cavity for installing the connector is opened inside one end of the connecting rod; a through hole is opened in the inner wall of the cavity; the connector includes a limiting block inserted inside the through hole for restricting the movement of the connecting rod, a baffle fixedly connected to one end of the limiting block for restricting the movement of the limiting block, and a push spring disposed on one side of the baffle for pushing the baffle. By inserting the connecting rod through the plug-in block, under the action of the push spring's restoring force pushing the baffle, the limiting block extends out of the through hole; under the action of the limiting block contacting the plug-in block, the movement of the connecting rod is restricted, thus completing the connection between the protective block and the second connecting frame.

[0010] Preferably, for sealing between the protective block and the second connecting frame: a first sealing ring for sealing between the protective block and the second connecting frame is fixedly connected to one end of the protective block facing the second connecting frame. The fixed connection between the protective block and the second connecting frame deforms the first sealing ring, thereby preventing rainwater from corroding the connecting screw through the gap between the protective block and the second connecting frame.

[0011] Preferably, to facilitate protection of one end of the connecting screw: a protective element is provided at the end of the protective block away from the second connecting frame, and a threaded post for connecting with the protective element is fixedly connected to the end of the protective block away from the second connecting frame. Through the threaded connection between the protective cover and the threaded post, the protective cover is fitted over the portion of the connecting screw that extends beyond the protective block, providing protection.

[0012] Preferably, to seal the gap between the protective block and the protective cover: the protective component includes a protective cover disposed on the end of the protective block away from the second connecting bracket to protect the connecting screw, and a second sealing ring fixedly connected to the end of the protective cover facing the protective block to seal between the protective cover and the protective block. The inner wall of the protective cover has connecting threads for engaging with the threaded post. The connection between the protective cover and the protective block compresses the second sealing ring, thereby sealing the gap between the protective block and the protective cover.

[0013] This application utilizes a design of a second connecting frame, an anti-detachment component, and a plug-in block. By simultaneously inserting the connecting screw into both the first and second connecting frames, the first and second connecting frames clamp the rails on both sides. Rotating the nut compresses the second connecting frame, thus fixing both the first and second connecting frames to the rails. A protective block is then fitted onto the end of the connecting screw, and a limiting block is pressed, allowing the connecting rod to pass through the plug-in block, restricting the movement of the protective block. Simultaneously, the nut compresses the push plate, which in turn compresses the push spring. The restoring force of the push spring acts in the opposite direction on the nut, pushing it closer to the second connecting frame. This prevents the nut from moving away from the second connecting frame under long-term vibration. Finally, a protective cover is fixedly connected to a threaded post via connecting threads, protecting the end of the connecting screw extending from the protective block and preventing rainwater erosion of the connecting screw threads, thus avoiding difficulty in disassembling the nut.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] This embodiment provides a railway sensor protection device, such as... Figure 1-8 As shown, the protective device is applied to rail 1, a first protective cover 2 and a second protective cover 3 symmetrically arranged on both sides of rail 1 for sensor protection, a first connecting frame 4 and a second connecting frame 5 symmetrically arranged on both sides of rail 1 for mounting the first protective cover 2 and the second protective cover 3, a connecting screw 6 inserted inside the first connecting frame 4 and the second connecting frame 5 for connecting the first connecting frame 4 and the second connecting frame 5, and a nut 7 sleeved on the outer wall of one end of the connecting screw 6 for restricting the movement of the second connecting frame 5.

[0026] To prevent the nut 7 from falling off: an anti-detachment component 8 is provided on the side of the second connecting frame 5 away from the rail 1 to prevent the nut 7 from falling off. The anti-detachment component 8 includes a protective block 81 sleeved on one end of the connecting screw 6, a push plate 82 provided inside the protective block 81 for contacting the nut 7, and a push spring 83 provided between the inner wall of the protective block 81 and the push plate 82 for pushing the push plate 82. By simultaneously inserting the connecting screw 6 into the interior of the first connecting frame 4 and the second connecting frame 5, the first connecting frame 4 and the second connecting frame 5 are clamped onto both sides of the rail 1. Then, by rotating the nut 7, the second connecting frame 5 is pressed, thereby fixing the first connecting frame 4 and the second connecting frame 5 onto both sides of the rail 1. Then, the protective block 81 is fitted onto the end of the connecting screw 6, and the limiting block 851 is pressed. The connecting rod 84 is inserted into the plug block 9 to restrict the movement of the protective block 81. At the same time, the nut 7 will press the push plate 82, and the push plate 82 will press the push spring 83. The restoring force of the push spring 83 acts in the opposite direction on the nut 7, pushing the nut 7 towards the second connecting frame 5, thereby preventing the nut 7 from moving away from the second connecting frame 5 under long-term vibration. Then, the protective cover 871 is fixedly connected to the threaded post 88 through the connecting thread, thereby protecting the end of the connecting screw 6 that extends out of the protective block 81, thereby preventing the nut 7 from being difficult to disassemble due to rainwater erosion of the threads of the connecting screw 6.

[0027] Furthermore, the rail 1 is an existing rail. The first protective cover 2 and the second protective cover 3 are the same size and shape, and are symmetrically arranged on both sides of the rail 1. The first protective cover 2 and the second protective cover 3 are used to cover the outer wall of the existing shear force sensor, thereby preventing flying stones from damaging the shear force sensor. The first protective cover 2 is symmetrically arranged with first connecting brackets 4 at both ends. The first connecting brackets 4 and the first protective cover 2 are fixedly connected by bolts. The second protective cover 3 is symmetrically arranged with second connecting brackets 5 at both ends. The second connecting brackets 5 and the second protective cover 3 are fixedly connected by bolts. The first connecting brackets 4 and the second connecting brackets 5 are the same size and shape. The first connecting brackets 4 and the second connecting brackets 5 have slots on one side facing the rail 1 for locking the side of the rail 1. By inserting the connecting screw 6 into the inside of the first connecting brackets 4 and the second connecting brackets 5, and rotating the nut 7, the nut 7 pushes the second connecting bracket 5 to move towards the rail 1. Under the action of the connecting screw 6 and the nut 7, the first connecting brackets 4 and the second connecting brackets 5 are fixed on both sides of the rail 1, maintaining the protection of the sensor by the first protective cover 2 or the second protective cover 3.

[0028] Specifically, to facilitate the installation of the protective block 81 and the connecting screw 6: the protective block 81 has a cover groove for inserting the nut 7 at one end facing the second connecting frame 5. One side of the inner wall of the cover groove and one side of the push plate 82 have through holes for inserting the connecting screw 6. The push spring 83 and the push plate 82 are located inside the cover groove. By inserting the connecting screw 6 into the through holes of the protective block 81 and the push plate 82, the protective block 81 is positioned on one side of the second connecting frame 5. The size of the mounting groove matches the size of the nut 7, so that the nut 7 fits inside the cover groove. The cover groove is cylindrical, and two through holes are located at the middle of one end of the inner wall of the cover groove and the middle of the push plate 82, respectively. The size of the through holes matches the diameter of the connecting screw 6.

[0029] Specifically, to facilitate the connection between the protective block 81 and the second connecting frame 5: symmetrical connecting rods 84 for connecting to the second connecting frame 5 are fixedly connected to both sides of the outer wall of the protective block 81, and insertion blocks 9 for the connecting rods 84 to pass through are fixedly connected to the outer wall of the second connecting frame 5. The protective block 81 and the second connecting frame 5 are connected by inserting the connecting rods 84 into the insertion blocks 9 on the outer wall of the second connecting frame 5. The ends of the connecting rods 84 are welded and fixed to the contact parts with the outer wall of the protective block 81. The number and position of the insertion blocks 9 correspond to the number and position of the connecting rods 84. Two insertion blocks 9 are symmetrically arranged on both sides of the outer wall of the second connecting frame 5, and the contact parts of the insertion blocks 9 with the second connecting frame 5 are welded. The vertical cross-section of the insertion blocks 9 is U-shaped.

[0030] Specifically, to facilitate the fixed installation of the protective block 81 and the second connecting frame 5: the end of the connecting rod 84 is provided with a connecting member 85 for restricting the movement of the connecting rod 84. A cavity for installing the connecting member 85 is opened inside one end of the connecting rod 84, and a through hole is opened on the inner wall of the cavity. The connecting member 85 includes a limiting block 851 inserted inside the through hole for restricting the movement of the connecting rod 84, a baffle 852 fixedly connected to one end of the limiting block 851 for restricting the movement of the limiting block 851, and a pushing spring 853 provided on one side of the baffle 852 for pushing the baffle 852. By inserting the connecting rod 84 through the plug-in block 9, the limiting block 851 extends out of the through hole under the restoring force of the pushing spring 853 pushing the baffle 852. Under the contact between the limiting block 851 and the plug-in block 9, the movement of the connecting rod 84 is restricted, thus completing the connection between the protective block 81 and the second connecting frame 5. Both the baffle 852 and the push spring 853 are located inside the cavity. The size of the through hole is adapted to the size of the limiting block 851. The size of the baffle 852 is 1.2 times the size of the through hole. The push spring 853 is always in a compressed state inside the cavity.

[0031] More specifically, for sealing between the protective block 81 and the second connecting frame 5: a first sealing ring 86 is fixedly connected to the end of the protective block 81 facing the second connecting frame 5 for sealing between the protective block 81 and the second connecting frame 5. Through the fixed connection between the protective block 81 and the second connecting frame 5, the first sealing ring 86 is compressed and deformed, thereby preventing rainwater from corroding the connecting screw 6 through the gap between the protective block 81 and the second connecting frame 5. The first sealing ring 86 is bonded and fixed to the protective block 81; the first sealing ring 86 is a rubber ring.

[0032] Specifically, to facilitate protection of one end of the connecting screw 6: a protective element 87 is provided at the end of the protective block 81 away from the second connecting frame 5, and a threaded post 88 for connecting with the protective element 87 is fixedly connected to the end of the protective block 81 away from the second connecting frame 5. Through the threaded connection between the protective cover 871 and the threaded post 88, the protective cover 871 is fitted over the portion of the connecting screw 6 extending outside the protective block 81 for protection. The contact area between the threaded post 88 and the protective cover 871 is welded and fixed.

[0033] More specifically, to seal the gap between the protective block 81 and the protective cover 871: the protective component 87 includes a protective cover 871 disposed at the end of the protective block 81 away from the second connecting bracket 5 to protect the connecting screw 6, and a second sealing ring 872 fixedly connected to the end of the protective cover 871 facing the protective block 81 to seal the gap between the protective cover 871 and the protective block 81. The inner wall of the protective cover 871 is provided with connecting threads for engaging with the threaded post 88. Through the connection between the protective cover 871 and the protective block 81, the second sealing ring 872 is compressed, thereby sealing the gap between the protective block 81 and the protective cover 871. The connecting threads engage with the threads on the outer wall of the threaded post 88. Through the engagement of the threaded post 88 and the connecting threads, the protective cover 871 and the threaded post 88 are fixedly connected. At the same time, the second sealing ring 872 is compressed and deformed, sealing the gap between the protective block 81 and the protective cover 871, preventing external rainwater from entering the protective cover 871, thereby preventing the connecting screw 6 from being corroded by rainwater.

[0034] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
