Description

Technical Field

[0001] This utility model belongs to the field of gate axle pin sealing technology, specifically relating to an externally locking turnout axle pin sealing sand baffle. Background Technology

[0002] As a core component ensuring the safety of train turning and track changing, the external locking device of railway turnouts is exposed to the natural environment for a long time. A certain gap must be reserved between its locking hook and axle pin to meet the needs of movement. However, in severe weather conditions such as wind, sand, rain, and snow, or in working environments with high dust concentrations, this gap can easily become a channel for the intrusion of foreign objects such as sand, dust, and rain-snow mixtures.

[0003] Foreign objects can fill the gaps between the locking hook and the axle pin, increasing the resistance to movement and even causing jamming, directly threatening train safety. Currently, the industry commonly uses manual cleaning and lubrication to maintain device flexibility, typically weekly. However, this method has significant drawbacks: First, it involves a huge workload; frequent manual intervention not only increases the labor intensity of on-site staff but also significantly raises maintenance labor and material costs. Second, it presents significant hazard risks; if foreign objects intrude during maintenance intervals and are not detected in time, it can easily cause equipment jamming, resulting in insufficient reliability and serious safety risks. Third, it is economically inefficient; the long-term, continuous investment of manpower and lubricating materials accumulates into high maintenance costs, which is detrimental to improving railway operating efficiency.

[0004] Therefore, in response to the problem of foreign object intrusion in the gap between the locking hook and the axle pin of the external locking device of railway turnout, there is an urgent need for a technical solution that can block foreign object intrusion from the source and reduce maintenance dependence, so as to solve the core pain points of existing maintenance methods such as large workload, low reliability and poor economy. Utility Model Content

[0005] This utility model provides an externally locking turnout pin sealing sand baffle to solve the technical defects of existing maintenance methods, such as large workload, low reliability and poor economy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A sand-blocking plate for an externally locking turnout pivot pin includes: The substrate has a structure with one end open and the other end sealed. The sand-blocking component has one end connected to the top of the sealing end of the substrate via a pressure plate, and the other end can be away from or close to the top of the opening end of the substrate. The sand-blocking component has symmetrically opened movable openings. A locking hook is attached to the open end of the substrate and is adapted to the movable port; The mounting plate is vertically set at the bottom of the substrate sealing end, and the mounting plate has symmetrically formed grooves. The anti-jump buckle is movably connected to the locking hook.

[0007] Furthermore, the locking hook is vertically disposed on the open end of the substrate; When the sand-blocking component approaches and abuts against the top of the opening end of the substrate, the locking hook extends from the movable opening and connects with the anti-jump buckle to lock the sand-blocking component.

[0008] Furthermore, the sand-blocking component has a rectangular structure, and its width is greater than the width of the substrate.

[0009] Furthermore, the sand-blocking component is injection molded from high-strength nylon plastic.

[0010] Furthermore, the substrate has a U-shaped structure.

[0011] Furthermore, the groove has a U-shaped cross-section, and the opening of the groove faces the bottom of the substrate.

[0012] Furthermore, the pressure plate, sand-blocking component, and base plate are connected by fasteners.

[0013] Furthermore, the fastener is a bolt.

[0014] Furthermore, multiple fasteners are arranged at intervals along the length of the pressure plate.

[0015] Furthermore, the anti-jump buckle and the locking hook are axially perpendicular.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. A physical protective structure is formed by combining the base plate and the sand-blocking component. The sand-blocking component covers the gap area between the locking hook and the shaft pin, blocking the intrusion path of foreign objects such as sand and dust from the source. This avoids equipment jamming caused by the accumulation of foreign objects during maintenance intervals, significantly improving the operational reliability of the external locking device and reducing traffic safety risks. Secondly, after the sand-blocking plate is installed, there is no need to frequently invest manpower in cleaning and lubrication operations. This reduces the labor intensity of on-site workers and the consumption of materials such as lubricating grease, reducing long-term maintenance costs from both manpower and material perspectives, and solving the pain point of poor economy of existing methods. Furthermore, while achieving the sealing and sand-blocking function, the overall structure does not interfere with the core steering and track-changing function of the external locking device, demonstrating outstanding adaptability and practicality.

[0017] 2. When the sand-blocking component approaches and abuts against the top of the open end of the substrate, the locking hook extends from the movable opening of the sand-blocking component and connects with the anti-jump buckle to form a mechanical locking structure, so that the sand-blocking component and the open end of the substrate fit tightly together, eliminating the gap between the sand-blocking component and the substrate, further strengthening the sealing effect of the gap between the locking hook and the shaft pin, and effectively preventing foreign objects such as wind, sand, rain and snow from entering from the fitting area.

[0018] 3. The sand-blocking component adopts a rectangular structure and its width is greater than that of the base plate, which can extend beyond the coverage area of ​​the base plate from the left and right sides to form a wide protection.

[0019] 4. High-strength nylon plastic has excellent mechanical strength and can withstand external forces such as wind and sand impact and train vibration, preventing the sand-blocking parts from deforming or breaking; at the same time, the material has low density and lightweight characteristics, which will not increase the extra load on the turnout external locking device and will not affect the original operating accuracy of the equipment.

[0020] 5. The U-shaped structure forms side barriers, which can provide surrounding protection for the gap between the locking hook and the pin from the left, right and bottom. Combined with the top sand baffle, it creates an all-round sealed space, completely blocking the path of foreign objects from the side and bottom, and providing more comprehensive protection.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] To address the technical deficiencies mentioned in the background section, this embodiment provides an externally locking turnout pin sealing sand baffle.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings: See Figures 1-3This utility model provides an externally locking turnout pin sealing sand baffle, comprising: a base plate 1, which has an open end and a closed end; a sand baffle 6, one end of which is connected to the top of the closed end of the base plate 1 via a pressure plate 3, and the other end of which can be away from or close to the top of the open end of the base plate 1, and the sand baffle 6 has symmetrically opened movable openings; a locking hook 2, which is connected to the open end of the base plate 1 and is adapted to the movable opening; a mounting plate 7, which is vertically set at the bottom of the closed end of the base plate 1, and the mounting plate 7 has symmetrically opened grooves 8; and an anti-jump buckle 5, which is movably connected to the locking hook 2, and after the anti-jump buckle 5 is connected to the locking hook 2, the anti-jump buckle 5 and the locking hook 2 are axially perpendicular.

[0031] When using the above structure, first align the two grooves 8 on the mounting plate 7 with the two fixing screws on the U-shaped iron, and then snap the grooves 8 onto the outside of the fixing screws; then, manually lift the other end of the sand baffle 6 away from the opening end of the base plate 1 to expose the fixing screws; next, install a nut on the end of the fixing screws to fasten the mounting plate 7.

[0032] Because the locking hook 2 is compatible with the movable opening, the locking hook 2 separates from the movable opening during the process of manually lifting the other end of the sand-blocking component 6. After the mounting plate 7 is tightened, the other end of the sand-blocking component 6 is then manually laid flat on the top of the opening end of the base plate 1, and the top of the locking hook 2 extends out from the movable opening. Finally, the anti-jump buckle 5 is connected to the locking hook 2 so that the sand-blocking component 6 is located below the two anti-jump buckles 5, thereby locking the sand-blocking component 6 and forming a physical protective structure. This allows the sand-blocking component 6 to cover the gap area between the locking hook 2 and the shaft pin, blocking the intrusion path of foreign objects such as sand and dust from the source, avoiding equipment jamming caused by the accumulation of foreign objects during the maintenance interval, greatly improving the operational reliability of the external locking device, and reducing the risk of traffic accidents.

[0033] After the sand baffle is installed, there is no need to frequently invest manpower in cleaning and lubrication operations during long-term use. This reduces the labor intensity of on-site workers and the consumption of materials such as lubricating grease, thereby reducing long-term maintenance costs from both manpower and material perspectives and solving the pain point of poor economy of existing methods. In addition, the overall structure does not interfere with the core steering and track changing function of the external locking device while achieving the sealing and sand-blocking function, making it highly adaptable and practical.

[0034] like Figure 1 As shown, the locking hook 2 is vertically disposed on the open end of the substrate 1; wherein, when the sand-blocking member 6 is close to the top of the open end of the substrate 1 and abuts against the top of the open end of the substrate 1, the locking hook 2 extends out from the movable opening and connects with the anti-jump buckle 5 to lock the sand-blocking member 6.

[0035] When the other end of the sand-blocking component 6 is manually brought close to the top of the opening end of the base plate 1 and pressed against it, the locking hook 2 extends from the movable opening of the sand-blocking component 6 and connects with the anti-jump buckle 5 to form a mechanical locking structure, so that the sand-blocking component 6 and the opening end of the base plate 1 are tightly fitted, eliminating the gap between the sand-blocking component 6 and the base plate 1, further strengthening the sealing effect of the gap between the locking hook 2 and the shaft pin, effectively preventing foreign objects such as wind, sand, rain and snow from entering from the fitting point, and significantly improving the stability and reliability of the protective structure.

[0036] When the turnout is locked, the sand-blocking component 6 maintains a sealed posture through the locking structure, which neither interferes with the normal locking action of the locking hook 2 and the anti-jump buckle 5, but also continues to play a protective role under critical working conditions, ensuring the compatibility of the sealing function with the core locking function of the equipment.

[0037] In this embodiment, the sand-blocking component 6 is a rectangular structure, with a width greater than that of the base plate 1; the sand-blocking component 6 is injection molded from high-strength nylon plastic. In practice, the rectangular structure of the sand-blocking component 6, with a width greater than that of the base plate 1, extends beyond the coverage area of ​​the base plate 1 from both sides, forming a wide-area protection. This comprehensively blocks the lateral area of ​​the gap between the locking hook 2 and the pivot pin, preventing windblown sand and dust from flowing in through the gaps on both sides of the base plate 1. Compared to a structure with the same width as the base plate 1, the protective coverage is more comprehensive, further enhancing the effect of preventing foreign objects from entering at the source.

[0038] In addition, due to the excellent mechanical strength of high-strength nylon plastic, it can resist external forces such as wind and sand impact and train vibration, avoiding deformation or damage of the sand-blocking part 6; at the same time, the material has low density and lightweight characteristics, which will not increase the extra load on the turnout external locking device and will not affect the original operating accuracy of the equipment.

[0039] In this design, the substrate 1 has a U-shaped structure, the groove 8 has a U-shaped cross-section, and the opening of the groove 8 faces the bottom of the substrate 1. The U-shaped contour of the groove 8 can provide precise guidance for assembly, while increasing the contact area with the fixing screw. Combined with the downward force direction of the opening, it can resist the risk of loosening caused by train vibration, resulting in stronger assembly stability.

[0040] In this solution, the pressure plate 3, the sand-blocking component 6, and the base plate 1 are connected by fasteners 4. The fasteners 4 are bolts, and multiple fasteners 4 are arranged at intervals along the length of the pressure plate 3 to form a uniformly distributed multi-point fixation, which effectively disperses the external forces generated by train vibration and wind and sand impact, avoids local loosening, ensures that the sand-blocking component 6 and the base plate 1 are always tightly fitted, and ensures that the sealing and protection effect does not fail.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
