Abstract
Description
Technical Field
[0001] This utility model relates to the field of train track accessories technology, and in particular to a scratch-resistant bracket for a train track proximity switch and a train track detection system. Background Technology
[0002] In the field of railway track components, traditional railway track proximity switches typically use rigid, fixed brackets, such as welded metal brackets, which are installed beside the track or on sleepers. However, in actual use, when a train passes by, debris kicked up by the wheels, trackside obstructions, or accidental collisions with maintenance tools can easily scrape against the brackets. This scraping often causes the brackets to deform, leading to loosening or damage to the proximity switch. These problems severely affect the accuracy of the proximity switch's train position detection, necessitate frequent replacements, significantly increase maintenance costs, and impact the normal operation and stability of the railway track system. Utility Model Content
[0003] The purpose of this invention is to provide a scratch-resistant bracket for a train track proximity switch and a train track detection system to solve the problems existing in the prior art. The structure is simple, effectively reducing damage to the bracket and proximity switch, and effectively ensuring the stability and detection accuracy of the proximity switch.
[0004] To achieve the above objectives, this utility model provides the following solution:
[0005] This utility model provides a scratch-resistant bracket for a train track proximity switch, comprising: a fixed base, a mounting base, and an elastic reset mechanism. The fixed base is used for fixed connection with the track or sleeper; the mounting base is used for mounting the proximity switch; the elastic reset mechanism is connected between the fixed base and the mounting base, so that the mounting base can undergo buffer displacement relative to the fixed base when subjected to external force, and automatically reset to the initial detection position after the external force disappears.
[0006] Preferably, the elastic reset mechanism includes at least one reset spring, at least one fixing bolt and at least one fixing nut. The fixing seat is provided with multiple mounting holes. One end of the fixing bolt is fixedly connected to the fixing seat, and the other end passes through the mounting hole and is threadedly connected to the fixing nut. The reset spring is sleeved on the outside of the fixing bolt.
[0007] Preferably, the return spring is a helical spring.
[0008] Preferably, the number of reset springs is two, the number of fixing bolts is two, and the number of fixing nuts is two.
[0009] Preferably, the two ends of the return spring are fixedly connected to the fixed base and the mounting base by hooks, welding or threaded connections.
[0010] Preferably, a limiting structure is provided between the fixed base and the mounting base to limit the maximum buffer displacement of the mounting base relative to the fixed base.
[0011] Preferably, the mounting base is provided with a mounting groove or mounting hole adapted to the external dimensions of the proximity switch.
[0012] The present invention also provides a train track detection system, including a track, a proximity switch, and a bracket for fixing the proximity switch, wherein the bracket is a scratch-resistant bracket for the train track proximity switch as described in any one of the above-mentioned methods.
[0013] The present invention achieves the following technical advantages over the prior art:
[0014] This invention provides a scratch-resistant bracket for a train track proximity switch and a train track detection system. By incorporating an elastic reset mechanism, the mounting base can undergo buffer displacement when subjected to external impact, effectively preventing damage to the bracket and proximity switch caused by rigid collisions. Simultaneously, after the external force disappears, the mounting base automatically resets to its initial detection position, ensuring the stability and detection accuracy of the proximity switch. Furthermore, the limiting structure further restricts the maximum buffer displacement of the mounting base, preventing the proximity switch from detaching or being damaged due to excessive displacement. This scratch-resistant bracket has a simple structure, is easy to install, effectively reduces maintenance costs, and improves the operational stability and safety of the train track system.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0019] The purpose of this invention is to provide a scratch-resistant bracket for a train track proximity switch and a train track detection system to solve the problems existing in the prior art. The structure is simple, effectively reducing damage to the bracket and proximity switch, and effectively ensuring the stability and detection accuracy of the proximity switch.
[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] Example 1
[0022] This utility model provides a scratch-resistant bracket for a train track proximity switch, such as... Figure 1 As shown, the device includes: a fixed base 1, a mounting base 2, and a resilient reset mechanism. The fixed base 1 is used for fixed connection with the track or sleeper; the mounting base 2 is used for mounting the proximity switch; the resilient reset mechanism is connected between the fixed base 1 and the mounting base 2, allowing the mounting base 2 to undergo buffer displacement relative to the fixed base 1 when subjected to external force, and automatically reset to the initial detection position after the external force disappears. This structural design can effectively cope with the external impacts that the proximity switch may encounter in the train track environment. When there is an accidental collision such as gravel flying from the wheels, debris beside the track, or maintenance tools, the mounting base 2 can generate buffer displacement through the resilient reset mechanism under the action of external force, converting the impact force into the elastic potential energy of the resilient reset mechanism, thereby significantly reducing the direct damage to the proximity switch and the bracket itself. Automatic reset to the initial detection position after the external force disappears ensures that the proximity switch is always in a precise detection position, guaranteeing the accuracy and stability of its train position detection, avoiding detection errors caused by position changes, and thus ensuring the safety and reliability of the train track system operation.
[0023] In a preferred embodiment, the elastic reset mechanism includes at least one reset spring 3, at least one fixing bolt 4, and at least one fixing nut 5. The fixing base 1 has multiple mounting holes. One end of the fixing bolt 4 is fixedly connected to the fixing base 1, and the other end passes through the mounting hole and is threadedly connected to the fixing nut 5. The reset spring 3 is sleeved on the outside of the fixing bolt 4. This structural design makes the installation and fixation of the reset spring 3 more stable. Through the cooperation of the fixing bolt 4 and the fixing nut 5, the position of the reset spring 3 can be accurately positioned, ensuring that it will not shift or wobble during operation, and ensuring that the elastic force can exert its effect in the desired direction. The connection method of the fixing bolt 4 and the fixing nut 5 facilitates installation and disassembly, making subsequent maintenance or replacement of components such as the reset spring 3 easier, improving maintenance efficiency, shortening maintenance time, and reducing maintenance costs.
[0024] In a preferred embodiment, the return spring 3 is a helical spring, which has good elasticity and stability. It can produce relatively regular elastic deformation when subjected to external force, accurately buffering and dissipating the force according to the magnitude of the external force. Furthermore, after multiple extensions and retractions, it can maintain good elastic recovery performance, ensuring that the mounting base 2 can be effectively reset during long-term use, providing stable and reliable buffer protection for the proximity switch.
[0025] In a preferred embodiment, there are two return springs 3, two fixing bolts 4, and two fixing nuts 5. Using two return springs 3 provides a more balanced buffering and restoring force. When subjected to external force, the two springs act simultaneously, making the displacement of the mounting base 2 more stable, reducing tilting or eccentricity caused by uneven force, and improving the buffering effect. At the same time, the dual-spring structure increases the redundancy of the system to a certain extent. Even if one spring fails, the other spring can still provide partial buffering and restoring capacity, improving the reliability and durability of the entire scratch-resistant bracket.
[0026] In a preferred embodiment, the two ends of the return spring 3 are fixedly connected to the fixed base 1 and the mounting base 2 via hooks, welding, or threaded connections. These multiple connection methods provide greater flexibility, allowing for appropriate selection based on different usage scenarios, installation requirements, and manufacturing processes. Whether it's the convenience of hook connections, the high strength of welded connections, or the detachability of threaded connections, specific needs can be met. These reliable connection methods ensure a tight connection between the return spring 3 and the fixed base 1 and mounting base 2, preventing loosening even under long-term stress, vibration, and impact conditions, thus guaranteeing the normal operation of the elastic return mechanism.
[0027] In a preferred embodiment, a limiting structure is further provided between the fixed base 1 and the mounting base 2 to limit the maximum buffer displacement of the mounting base 2 relative to the fixed base 1. This limiting structure prevents excessive displacement of the mounting base 2 under excessive external force. Without this limiting structure, excessive displacement of the mounting base 2 under excessive external force may cause excessive deformation or even damage to the return spring 3, or damage to the connection structure between the mounting base 2 and the fixed base 1. The limiting structure effectively protects the return spring 3 and other related components, extending their service life. Simultaneously, it ensures that within the normal operating range, the mounting base 2 can fully utilize its buffer displacement function without exceeding reasonable displacement limits, thus ensuring the stability and safety of the system.
[0028] In a preferred embodiment, the mounting base 2 is provided with a mounting groove 6 or mounting hole adapted to the external dimensions of the proximity switch. This adaptation design ensures that the proximity switch is securely mounted on the mounting base 2. The size of the mounting groove 6 or mounting hole is adapted to the shape of the proximity switch, allowing for a tight fit and preventing the proximity switch from shaking or shifting during operation. This ensures the installation stability of the proximity switch and thus guarantees its detection accuracy. At the same time, this precise adaptation design also facilitates the installation and removal of the proximity switch, improving installation efficiency and maintenance convenience.
[0029] Example 2
[0030] This embodiment also provides a train track detection system, including a track, a proximity switch, and a bracket for fixing the proximity switch. The bracket is a scratch-resistant bracket for the train track proximity switch as described in any of the embodiments in Part 1. Applying the scratch-resistant bracket to the train track detection system greatly improves the anti-interference capability and stability of the entire system. When various factors around the track may cause damage to the proximity switch, the scratch-resistant bracket can effectively protect the proximity switch, greatly reducing the risk of failure caused by accidental scratches, collisions, etc. The stable operation of the proximity switch ensures the accuracy and reliability of the train track detection system in detecting train position, helps to obtain train operation status information in a timely and accurate manner, provides strong support for the safe operation and management of train tracks, and improves the safety, efficiency, and quality of the entire railway transportation system.
[0031] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
