Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traffic turnouts, in particular to a pad structure for realizing the locking of a point rail. Background Art
[0002] A turnout locking device is typically used at the tip of a turnout switch rail to prevent it from rotating, thereby securing the turnout's direction. This device is often used for safety reasons when the other side of the turnout needs to be temporarily opened to traffic during turnout overhaul, when the turnout switch system has not been installed in a timely manner, or when the turnout has been operating on one side for a long time. This lock ensures unilateral operation of the switch rail, thus ensuring the turnout's direction of rotation.
[0003] Conventional turnout lockers do not have a safety locking mechanism for the movable locking block. They are easily loosened by human intervention during use, or due to the vibration of the turnout point rail, which can cause shunting safety problems. Secondly, other turnout locking devices usually use a splint and spike fixation method to lock the turnout, that is, the splint is used to tighten the point rail, and the spikes are hammered into the sleepers along the edge of the splint. This fixing method has the following disadvantages: (1) Hammering the spikes into the sleepers to fix the splint can easily damage the sleepers; (2) The spikes are easy to loosen, making the turnout lock ineffective; (3) It is not very applicable. For cement sleeper turnouts, this solution is not feasible. Utility Model Content

[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.
[0025] The following is combined with Figure 1-3 This application is described in further detail.
[0026] An embodiment of the present application discloses a pad structure for achieving point rail locking.
[0027] Reference Figure 1 and Figure 2 The pad structure for locking the point rail 1 includes a point rail 1, a slide bed plate 5 and a gusset plate 2; the point rail 1 is installed on the steel rail to change the travel path of the train, and a mounting edge is provided at the bottom of the point rail 1; the slide bed plate 5 is located on one side of the steel rail, and the slide bed plate 5 is supported below the mounting edge of the point rail 1 and provides sliding support for the point rail 1; the gusset plate 2 is detachably installed on the slide bed plate 5, and a pressing tongue 7 is formed at one end of the gusset plate 2, and the pressing tongue 7 of the gusset plate 2 is located above the mounting edge of the point rail 1, and a clamping space for fixing the point rail 1 is formed between the pressing tongue 7 of the gusset plate 2 and the slide bed plate 5.
[0028] The point rail 1 is a key component mounted on the rail, used to change the train's path. The bottom of the point rail 1 is provided with a mounting edge, allowing it to be securely fixed to the slide plate 5 and slide when needed to switch tracks. The slide plate 5 is located on one side of the rail and supported below the mounting edge of the point rail 1. Its primary function is to provide a stable sliding support platform for the point rail 1. The design of the slide plate 5 not only supports the point rail 1 but also, through its rational structural design, ensures smooth movement when switching paths and prevents it from bouncing up and down during operation. The pinch plate 2 is removably mounted on the slide plate 5, with a retaining tongue 7 formed at one end. The retaining tongue 7 of the pinch plate 2 is located above the mounting edge of the point rail 1. This structure creates a clamping space between the retaining tongue 7 of the pinch plate 2 and the slide plate 5. This clamping space secures the point rail 1, preventing it from loosening or shifting when a train passes. In a specific implementation, the pressing tongue 7 of the pinch plate 2 presses the slide bed 5 tightly against the mounting edge of the switch rail 1, thereby effectively limiting the up and down movement of the switch rail 1 and improving the stability of the switch rail 1. The distance between the lower surface of the pressing tongue 7 of the pinch plate 2 and the slide bed 5 gradually decreases from the side close to the rail to the side away from the rail.
[0029] The slide bed 5 has a mounting slot, into which the gusset plate 2 is inserted and secured to the slide bed 5 via bolts 4. The mounting slot design allows the gusset plate 2 to be inserted and secured to the slide bed 5 via bolts 4. This structure ensures the gusset plate 2 remains stable during use, preventing loosening or displacement due to vibration or external forces, thereby improving the locking effect of the switch rail 1 and the reliability of the entire system. To further optimize this design, the following details can be added during implementation: First, the mounting slot can be designed to provide a certain guiding function, such as a trapezoidal or tapered slot, to ensure that the gusset plate 2 is accurately positioned and securely fixed. Second, anti-loosening devices, such as spring washers or lock nuts, can be added to the bolt 4 connection to further prevent the bolt 4 from loosening. Furthermore, the inner wall of the mounting slot or the contact surface of the gusset plate 2 can be provided with an anti-slip texture or coated with a high-friction material to increase the stability and friction of the gusset plate 2, ensuring its reliability during long-term use. Through the implementation of these details, the connection between the slide bed plate 5 and the gusset plate 2 will be more stable and durable, further improving the safety and service life of the locking device of the point rail 1.
[0030] The mounting slot is opened in a direction perpendicular to the rail, and the gusset plate 2 is slidably arranged in the mounting slot along the length of the mounting slot. An adjustment plate 3 for limiting the position of the gusset plate 2 is inserted into at least one end of the mounting slot. The purpose of this structure is to provide precise control over the position of the gusset plate 2, ensuring that the gusset plate 2 can slide adjustably within the slot while limiting its fixation in a specific position to accommodate different specifications of the point rail 1 or specific site requirements. Through this design, the adjustment plate 3 not only prevents the gusset plate 2 from shifting or sliding due to vibration or external force during use, but also allows the fine-tuning function of the adjustment plate 3 to accurately set the final position of the gusset plate 2, ensuring the optimal fit between the gusset plate 2 and the point rail 1.
[0031] In practice, the following details could be added to further optimize the functionality and reliability of this structure: the interior of the mounting slot could be textured with an anti-slip texture or made of a high-friction material to enhance the stability of the pinch plate 2 during adjustment. Furthermore, the adjustment plate 3 could be constructed from a wear-resistant and elastic material, such as spring steel or high-strength plastic, to ensure effective positioning during long-term use. These optimizations would further enhance the adaptability and stability of the entire device, helping to extend its service life and ensure the safe operation of the switch rail 1.
[0032] Reference Figure 3The gusset plate 2 has a waist-shaped hole 6 perpendicular to the rail, through which the bolt 4 is threaded into the slide bed 5. This structural design allows for a certain degree of adjustment of the gusset plate 2 during installation. The shape of the waist-shaped hole 6 allows for fine-tuning of the gusset plate 2 perpendicular to the rail, thereby better aligning the relative position between the switch rail 1 and the slide bed 5. This ensures that the gusset plate 2 precisely locks the switch rail 1, enhancing the flexibility and adaptability of the overall locking system. This design is particularly helpful in addressing actual on-site errors or subtle differences between the switch rail 1 and the slide bed 5 during installation.
[0033] In specific implementation, the following details can be added to further optimize the function of this structure: First, the length and width of the waist-shaped hole 6 can be optimized according to actual needs to provide a sufficient adjustment range while ensuring that the bolt 4 can be firmly locked after adjustment; second, an anti-loosening device, such as a spring washer or an anti-loosening nut, can be added between the bolt 4 and the waist-shaped hole 6 to prevent the bolt 4 from loosening due to vibration during use after adjustment; in addition, the edge of the waist-shaped hole 6 can be reinforced, such as adding a bushing or using high-strength materials, to prevent the hole from wearing during frequent adjustments or long-term use, thereby ensuring the durability and reliability of the entire connection system. Through the optimization of these details, the installation and adjustment of the gusset plate 2 will be more precise and stable, which will help to extend the service life of the locking device of the point rail 1.
[0034] Multiple pinch plates 2 are spaced apart along the length of the switch rail 1. This structural design evenly distributes the locking force on the switch rail 1, ensuring stable fixation throughout its entire length, effectively preventing the switch rail 1 from tilting, shifting, or loosening during train traffic. This distribution disperses concentrated force, reducing stress at a single location, extending the service life of the switch rail 1 and pinch plates 2, and improving the reliability of the entire locking mechanism.
[0035] The upper surface of the slide bed 5, on the side closest to the rail, is convex to form a support edge for the switch rail 1. A clearance space is formed below the support edge to allow the rail to clear the switch rail. This structural design provides more stable support for the switch rail 1, ensuring stability during the switching process and preventing interference or friction between the switch rail 1 and the slide bed 5. The convex support edge ensures that the switch rail 1 always has a reliable support point during sliding, while the clearance space prevents collision or contact between the switch rail 1 and the rail under different positions or operating conditions, thereby protecting the surface integrity of the rail and switch rail 1 and extending their service life.
[0036] The lower surface of the slide bed 5 is provided with a weight-reducing groove 8, extending perpendicularly to the rail. This structural design primarily reduces the overall weight of the slide bed 5, thereby lowering the manufacturing cost and installation difficulty of the entire point rail 1 locking device, while also reducing the burden on the track structure. Through the design of the weight-reducing groove 8, the slide bed 5 can optimize material usage and reduce unnecessary material accumulation while maintaining sufficient structural strength and stability, which helps improve the convenience of transportation and installation. Furthermore, the weight-reducing groove 8 can also improve the heat dissipation performance of the slide bed 5 to a certain extent, preventing the degradation of material properties due to heat accumulation in high-temperature environments.
[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
