Technical Field

[0001] The present invention relates to the field of sensors, and in particular, to an ice and dust removal device for a travel sensor. Background Art

[0002] In extremely cold areas such as Northeast China and Inner Mongolia, the winter temperature often drops to dozens of degrees below zero. For travel sensors with moving parts, the working environment is often harsh, which may lead to a series of serious consequences. For example, when a travel sensor monitors a steel wire rope, due to the harsh temperature, ice may form on the surface of the steel wire rope, resulting in jamming of the moving parts and inaccurate monitoring of key data.

[0003] In the prior art, a method of applying an anti-icing coating with anti-wear, anti-slip, and lubricating properties on the surface of the steel wire rope is used to improve the surface friction coefficient of the steel wire rope and reduce the possibility of ice formation on the surface of the steel wire rope. However, the usage environment of the steel wire rope is often very complex, and it needs to experience changes such as sand and dust, rain and snow, high temperature, and low temperature. Its coefficient constantly changes, and the coating is easily damaged and needs to be frequently reapplied. During operation, the loss of the coating causes the steel wire rope to easily freeze, resulting in component jamming and inaccurate monitoring of key data. Summary of the Invention

[0006] When a steel wire rope passes through the hole in a vertical direction and the steel wire rope moves in a vertical direction during operation, relative movement occurs between the steel wire rope and the hole at the center of the wire passing device, thereby removing the ice layer on the surface of the steel wire rope.

[0007] Furthermore, the wire passing device is made of ceramic material to improve the wear resistance and corrosion resistance of the wire passing device.

[0008] Furthermore, an outlet nozzle for protecting the hole from rain and foreign object erosion is arranged on the outer surface of the wire passing device. The outlet nozzle is in a tapered shape with a narrower bottom and a wider top to quickly discharge the condensed water formed after removing the ice layer on the surface of the steel wire rope.

[0009] Furthermore, the thickness of the outlet nozzle is 1 mm to 3 mm to improve the stability of the outlet nozzle. The outlet nozzle has a cavity structure for installing the wire passing device.

[0010] Further, a U-shaped groove for guiding is arranged inside the protective housing, and the U-shaped groove is detachably connected with a bearing through a fitting to reduce the movement resistance of the steel wire rope.

[0031] The following further describes the present disclosure in conjunction with the embodiments shown in the drawings.

[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0033] The present invention provides an ice and dust removal device for a travel sensor. When the steel wire rope moves, it generates friction with the wire passing device, removing the ice layer on the surface of the steel wire rope. Compared with the traditional method, the adopted friction technology further avoids the situation of component jamming and inaccurate monitoring of key data. At the same time, it saves labor costs, uses natural factors to remove the ice layer, and reduces maintenance costs.

[0034] Embodiment 1

[0035] Figure 1 This is an ice and dust removal device for a travel sensor provided by an embodiment of the present disclosure. As Figure 1 shown:

[0036] An ice and dust removal device for a travel sensor includes a protective housing 1 for wrapping the sensor. A wire passing device 2 for removing the ice layer on the surface of the steel wire rope is provided below the protective housing 1. A hole position through which only the steel wire rope can pass is provided at the center of the wire passing device 2;

[0037] When a steel wire rope passes vertically through the hole position and moves vertically during operation, relative movement occurs between the steel wire rope and the hole position at the center of the wire passing device 2, thereby removing the ice layer on the surface of the steel wire rope.

[0038] In this embodiment, it includes a protective housing 1 for wrapping the sensor. A wire passing device 2 for removing the ice layer on the surface of the steel wire rope is provided below the protective housing 1. A hole position is provided at the center of the wire passing device 2, and the hole position penetrates from the top to the bottom of the wire passing device 2, and the center hole diameter is relatively small;

[0039] Pass the wire rope through the hole. When the wire rope moves, it will be repeatedly pulled out and retracted. To ensure the movement space, the overall structure of the designed travel sensor is non-closed. At the same time, it generates friction with the wire rope guide 2 to remove the fine ice layer on the surface of the wire rope, preventing the wire rope from freezing and causing jamming, and the key data cannot be accurately monitored.

[0040] In this solution, the ambient temperature around the wire rope is low and it is easy to freeze. Moreover, the ice layer on the surface of the wire rope is very thin and it is difficult to manually remove it completely.

[0041] However, during the movement of the wire rope, the frictional effect between the wire rope and the surface of the wire rope guide 2 can completely remove the ice layer, improving the frictional effect of the wire rope, thereby improving the measurement accuracy and reliability.

[0042] If the wire rope guide 2 is not used, the wire rope will directly rub against the surface of the fixed equipment. The ice layer on the surface of the wire rope is not easy to remove, which not only easily damages the travel sensor, but also affects the measurement accuracy. Therefore, using the wire rope guide 2 can effectively protect the travel sensor and extend its service life.

[0043] The wire rope guide 2 also plays a guiding role during the movement of the wire rope, preventing it from deviating from the movement track, and at the same time can also play a role in removing the ice layer on the surface of the wire rope.

[0044] The ice layer on the surface of the wire rope not only affects the measurement accuracy, but also easily causes the wire rope to break and fracture, affecting the normal operation of the equipment. Using the wire rope guide 2 to remove the ice layer on the surface of the wire rope can effectively reduce the risk of the wire rope breaking and fracturing, thereby reducing the failure rate and maintenance cost during equipment operation.

[0045] In summary, passing the wire rope through the hole of the wire rope guide 2 and removing the ice layer on its surface during the movement of the wire rope can improve the frictional effect, extend the service life of the travel sensor, reduce the failure rate, and is beneficial to the measurement work and equipment operation.

[0046] During use, pass the wire rope through the hole of the wire rope guide 2. At the same time, the wire rope is repeatedly pulled out and retracted during the operation, and moves and rubs against the hole of the wire rope guide 2. During the friction process, the ice layer on the surface of the wire rope is removed through the action of friction force.

[0047] In this embodiment, the wire rope guide 2 is made of ceramic material to improve the wear resistance and corrosion resistance of the wire rope guide 2.

[0048] In this solution, the wire rope guide 2 is made of ceramic material. The ceramic material has very high hardness and can withstand high-strength forces and heavy pressures. Therefore, the wire rope guide 2 made of ceramic material can be more wear-resistant, durable, and have a longer service life.

[0049] Ceramic materials have excellent high-temperature resistance, can maintain stable performance in high-temperature environments, are not prone to expansion, are not easy to deteriorate, and are suitable for applications in high-temperature environments;

[0050] Ceramic materials have very good corrosion resistance and can be used in high-humidity, acidic or alkaline environments. In industrial production, in places with harsh environments and strong corrosion;

[0051] For example, in steel mills, chemical plants, etc., the wire threading device 2 made of ceramic materials can have stable performance and a long service life on the premise of ensuring quality;

[0052] The friction coefficient of ceramic materials is very small. Therefore, the friction loss between the travel sensor and the surface of the steel wire rope can be minimized. Using the ceramic wire threading device 2 to rub the surface of the steel wire rope can effectively remove obstacles such as icing, thereby reducing the wear of the steel wire rope and the travel sensor, increasing its service life, and ensuring accuracy;

[0053] In this solution, the ceramic material of the wire threading device 2 can also be replaced by other materials. For example, metal materials can be used. Metal materials usually include stainless steel, chrome steel, and aluminum alloy, etc. These materials have high strength and durability, and can easily rub the surface of the steel wire rope to remove icing;

[0054] Metal materials usually have high hardness and strength and can withstand high-intensity forces and heavy pressures. The wire threading device 2 manufactured in this way can be more wear-resistant and durable, with a longer service life. At the same time, the strength and stiffness of metal materials can help measure the friction on the surface of the steel wire rope more accurately, improving the accuracy and reliability of the travel sensor;

[0055] Metal materials often have good high-temperature resistance, can maintain stable performance in high-temperature environments, and are not easy to deform or change color, suitable for applications in high-temperature environments;

[0056] Metal materials are relatively easy to process and trim, can be adjusted and improved according to actual needs, and ensure the quality and accuracy of the wire threading device 2;

[0057] At the same time, because the chemical properties of metal materials are relatively stable, they have good corrosion resistance and can be used in acidic, alkaline and other environments;

[0058] The friction coefficient between metal materials and the steel wire rope is small. Using the metal wire threading device 2 to rub the surface of the steel wire rope can effectively remove obstacles such as icing, thereby reducing the wear of the steel wire rope and the travel sensor, increasing its service life, and ensuring accuracy.

[0059] In this embodiment, an outlet nozzle 3 for protecting the hole position from rainwater and foreign object erosion is provided on the outer surface of the wire threading device 2.

[0060] In this embodiment, the wire outlet nozzle 3 is in a tapered shape with a narrower lower part and a wider upper part, so as to quickly drain the condensed water formed after removing the ice layer on the surface of the wire rope.

[0061] In this embodiment, the thickness of the wire outlet nozzle 3 is 1 mm to 3 mm, so as to improve the stability of the wire outlet nozzle 3.

[0062] In this solution, using a wire outlet nozzle 3 with a thickness of 1 mm to 3 mm can enhance its hardness and durability, make it more wear-resistant and fatigue-resistant, and extend its service life;

[0063] The diameter and thickness of the wire outlet nozzle 3 can affect the diameter and strength of the wire rope. A thicker wire outlet nozzle 3 can not only ensure that the outlet diameter does not deform, but also effectively control the diameter and strength of the wire rope, improving safety;

[0064] Selecting a wire outlet nozzle 3 with a uniform thickness and a smooth surface can reduce the outlet error and ensure the maximum strength of the wire rope and the accuracy of the target setting;

[0065] Using a wire outlet nozzle 3 with a thickness of 1 mm to 3 mm can improve the production efficiency of the industry and reduce costs. Compared with manual operation, using the wire outlet nozzle 3 can thread the wire rope more conveniently and quickly, increasing the production efficiency;

[0066] The working environment of the wire rope is usually relatively harsh. The design of the wire outlet nozzle 3 with a uniform thickness can reduce the error in the strength of the wire rope and reduce the splash during outlet, avoiding the occurrence of dangerous accidents;

[0067] In summary, using a wire outlet nozzle 3 with a thickness of 1 mm to 3 mm can enhance hardness and durability, reduce the outlet diameter, reduce errors, improve the use efficiency and avoid potential safety hazards. Therefore, when selecting the wire outlet nozzle 3, it is necessary to consider the quality of uniform thickness and smooth surface to give full play to its advantages and improve the production efficiency and quality level.

[0068] In this embodiment, the wire outlet nozzle 3 has a cavity structure for installing the wire passer 2.

[0069] In this solution, the cavity structure of the wire outlet nozzle 3 enables the wire rope cable to pass through the wire outlet nozzle 3 more smoothly, reduces the resistance during outlet, and improves the production efficiency;

[0070] At the same time, the design of the wire outlet nozzle 3 with a cavity structure can reduce the resistance and friction generated, avoid uneven rotation, and increase the stability of the wire rope;

[0071] The cavity structure of the wire outlet nozzle 3 allows the wire rope to pass through smoothly during outlet, reduces the risk of the wire rope cracking and twisting during outlet, and provides a safer outlet environment under high-strength conditions;

[0072] The cavity structure of the wire outlet nozzle 3 can keep the wire rope in its original shape, reduce the possibility of deformation and skew, and improve the diameter accuracy of the wire rope;

[0073] Using the wire outlet nozzle 3 with a cavity structure can reduce resistance and friction, improve production efficiency and reduce production costs.

[0074] The wire outlet nozzle 3 is provided at the bottom of the sensor, and the wire passer 2 is fixed to the wire outlet nozzle 3. The wall thickness of the wire outlet nozzle 3 is in a conical structure with a narrower bottom and a wider top, and the inner diameter decreases with height. External condensate can be quickly discharged along the conical surface, and the cavity structure also plays a protective role for the position of the wire outlet hole, blocking the intrusion of external rainwater or foreign objects.

[0075] Since the wall thickness of the wire outlet nozzle 3 is in a conical structure with a narrower bottom and a wider top, and the inner diameter decreases with height, the fluidity of the wire rope can be gradually enhanced, avoiding excessive friction and impact when the wire rope passes through the wire outlet nozzle 3, thereby reducing the pressure on the travel sensor and protecting the normal operation of the travel sensor;

[0076] After the wire rope passes through the wire outlet nozzle 3, the conical structure with an inner diameter decreasing with height restricts the free movement of the wire rope, making the movement trajectory of the wire rope more regular and the measurement accuracy higher;

[0077] The wall thickness of the wire outlet nozzle 3 being in a conical structure with a narrower bottom and a wider top can ensure the stable movement of the wire rope when passing through the wire outlet nozzle 3, reduce the problems of wire rope winding and deviation, and avoid unnecessary shutdown for maintenance;

[0078] The wall thickness of the wire outlet nozzle 3 is in a conical structure with a narrower bottom and a wider top, and the inner diameter decreasing with height can restrict the flow speed of the wire rope, avoid the wire rope speed being too fast, increase the probability of accidental accidents, and improve the safety of the equipment in use;

[0079] In summary, the wall thickness of the wire outlet nozzle 3 is in a conical structure with a narrower bottom and a wider top, and the inner diameter decreasing with height has the advantages of protecting the travel sensor, ensuring measurement accuracy, reducing wire rope winding, and improving the safety of the equipment, and plays an important role in the process of wire rope measurement.

[0080] When in use, when the wire rope passes through the hole of the wire passer 2, the wire rope is pulled out from one end of the wire outlet nozzle 3, so that the wire outlet nozzle 3 can play a protective role for the hole of the wire passer 2.

[0081] Embodiment 2:

[0082] On the basis of Embodiment 1, as Figure 2 shown:

[0083] In this embodiment, a U-shaped groove 4 for guiding is provided inside the protective housing 1.

[0084] The provision of the U-shaped groove 4 can keep the wire rope stable and prevent it from jittering and deviating during movement. This is achieved by guiding the movement of the wire rope so that it can pass smoothly through the sensor without being interfered by the outside world;

[0085] The provision of the U-shaped groove 4 can avoid the possibility of the wire rope disengaging from the sensor and being worn due to friction. This can also prevent any potential hazards, thereby enhancing the safety of the workplace;

[0086] The provision of the U-shaped groove 4 can reduce the friction between the wire rope and the external environment, thereby reducing wear. This can also extend the service life of the sensor;

[0087] The provision of the U-shaped groove 4 can improve the accuracy when the wire rope passes through the sensor, because the wire rope can pass through the sensor accurately, thereby eliminating any possible errors;

[0088] In summary, installing the U-shaped groove 4 to guide the direction of the wire rope can stabilize the relationship between the sensor and the wire rope, improve safety and accuracy, and reduce wear; this is a very good solution, especially in application scenarios that require high precision and stability.

[0089] In actual situations, a V-shaped groove can also provide better positioning accuracy because it provides more support on both sides of the object. V-shaped grooves are often used in occasions that require precise positioning, such as in the processing and manufacturing industries;

[0090] The design of the V-shaped groove can provide better positioning accuracy because it provides more support on both sides of the object; different from the U-shaped groove, the V-shaped groove avoids the contact between the object and the side wall of the guiding groove, so the object can be positioned more accurately;

[0091] Since the V-shaped groove provides support on both sides, it is suitable for guiding some larger objects; some larger objects may wobble or be unstable in the U-shaped groove, but can be provided with better support and stability in the V-shaped groove;

[0092] Since the surface of the object in contact with the side wall is smaller when the object moves in the V-shaped groove, the friction and wear between the object and the guiding groove can be reduced. This can extend the service life of the object and the guiding groove;

[0093] Since the V-shaped groove can better position the object and provide better support and stability, it can improve the safety of the workplace. At the same time, it can prevent the object from sliding, tilting or falling off, thereby preventing potential hazards;

[0094] In actual situations, for circular or curved objects, a circular groove can be used for guiding. The circular groove allows the object to move along its circumference while remaining stable;

[0095] The circular groove can be applicable to objects with circular or curved shapes because the object can move along its circumference while maintaining good stability;

[0096] The circular groove can provide equal support and balance, which is very important for applications that require high positioning accuracy;

[0097] Compared with guiding grooves of other shapes, the circular groove can provide more stable positioning because the object can provide a completely balanced support point within the ring, unlike V-shaped or U-shaped grooves that may deform at the bends;

[0098] The circular groove does not cause as much wear as guiding grooves of other shapes. Since the object can move along its circumference, the contact surface area between the object and the groove is relatively small, which means less wear and a longer service life;

[0099] In some applications, such as in high-speed motion scenarios, collisions between objects may pose risks or adverse effects. Using a circular groove for guiding can avoid such situations because objects moving within the groove cannot collide with each other.

[0100] In actual situations, T-shaped grooves are usually used for objects that require vertical positioning. They provide two support surfaces, making the object more stable when rising perpendicular to their edges;

[0101] The T-shaped groove can provide two support surfaces, which is very important for objects that require precise vertical positioning. If the object moves inside the T-shaped groove, it can be well aligned along its edge, thus achieving precise positioning;

[0102] Furthermore, the T-shaped groove can ensure that the object always moves in the horizontal direction, thereby improving the positioning accuracy and stability;

[0103] The design of the T-shaped groove makes the direction of the object more controllable during movement. Since the object can only move along the edge of the T-shaped groove inside the groove, the direction of the object can be effectively controlled;

[0104] When the object needs to be fixed or stationary, the T-shaped groove can provide more stable support, preventing the object from tilting or moving;

[0105] Compared with V-shaped or U-shaped grooves, the T-shaped groove can save more installation space because it only needs to provide support where precise positioning of the object is required;

[0106] In summary, the design of the T-shaped groove can offer many advantages. It can provide precise vertical positioning, improve positioning accuracy, control the movement direction, prevent the object from tilting or moving, and save installation space. In applications that require vertical positioning and precise positioning of objects, the T-shaped groove is a very ideal guiding groove design.

[0107] In actual situations, for square-angled objects, the square groove is a good choice. The square groove provides four supporting surfaces, making the object more stable;

[0108] The square groove design can provide four equal supporting surfaces, which can help the object maintain balance and stability, and is especially suitable for applications that require improved positioning accuracy and stability;

[0109] Due to the large internal space and multiple supporting surfaces of the square groove, it is suitable for guiding objects of different shapes and sizes;

[0110] The square groove can ensure that the object always moves in the horizontal direction, thereby improving positioning accuracy and stability. At the same time, the four-sided support can prevent the object from tilting or shaking;

[0111] Collision between objects can be avoided: In some applications, collisions between objects may cause danger or adverse effects. Using a square groove can avoid this situation because the objects moving in the groove cannot collide with each other;

[0112] Compared with guiding grooves of other shapes, the square groove has less wear because the contact surface area between the object and the side wall of the guiding groove is relatively small;

[0113] In summary, the design of the square groove can offer many advantages. It can provide a stable supporting surface, is suitable for guiding objects of different shapes and sizes, improve positioning accuracy, avoid collisions between objects, and reduce wear. In applications that require high-precision guiding and stability, the square groove is an ideal guiding groove design.

[0114] In this embodiment, the U-shaped groove 4 is detachably connected with a bearing 5 through a fitting to reduce the movement resistance of the steel wire rope.

[0115] The combination of the U-shaped groove 4 and the bearing 5 can provide a smoother movement path for the moving steel wire rope, thereby reducing the frictional resistance of the steel wire rope and improving the conveying efficiency;

[0116] The cooperation between the U-shaped groove 4 and the bearing 5 can fix the bearing 5 more firmly in place and bear a greater load. This can improve the service life and safety of the equipment;

[0117] The connection between the U-shaped groove 4 and the bearing 5 is achieved through the disassembly of the fittings, which makes it more convenient to maintain or replace the bearing 5 without the need for large-scale disassembly and assembly of the entire equipment;

[0118] When the steel wire rope moves in the U-shaped groove 4 and the bearing 5, its movement is more stable and uniform, which can reduce noise and vibration, and improve transportation efficiency and operation comfort;

[0119] The combined design of the U-shaped groove 4 and the bearing 5 can reduce the friction between the equipment components, thereby reducing the friction loss of the equipment and extending the service life of the equipment;

[0120] In summary, the design method of combining the U-shaped groove 4 with the bearing 5 through the disassembly connection of the fittings can improve the transportation efficiency, load-bearing capacity and safety of the equipment, reduce noise, vibration and friction loss of the equipment, and provide greater convenience for maintenance and replacement work. These advantages make the combined design of the U-shaped groove 4 and the bearing 5 widely applicable in the fields of logistics transmission and transportation equipment, etc.

[0121] In this embodiment, the bearing 5 is made of stainless steel material to improve the corrosion resistance of the bearing 5.

[0122] In this solution, the corrosion resistance of the stainless steel material is much higher than that of other metal materials. Therefore, when used in harsh environments, such as the ocean, chemical industry, tropical high-temperature regions, etc., the stainless steel bearing 5 is not easy to rust, corrode or degenerate, thus ensuring the operation efficiency and stability of the equipment;

[0123] Due to the friction and wear of the steel wire rope, the wear resistance of the U-shaped groove 4 and the bearing 5 is very important. The stainless steel material has high hardness and subsurface hardening properties, which can improve the wear resistance of the bearing 5, reduce the wear of the U-shaped groove 4 and the bearing 5, and thus protect the equipment and extend the service life;

[0124] The stainless steel bearing 5 has high surface smoothness and precision. This can reduce the friction resistance when the steel wire rope passes through the U-shaped groove 4, thereby improving the transportation efficiency and speed of the equipment;

[0125] In actual situations, in some occasions that require safety protection, such as building material hoisting, mine coal mining, bridge hoisting, etc., the stainless steel bearing 5 can provide additional protection against theft because they cannot be easily cut or damaged;

[0126] For some occasions with special requirements, such as food processing, medical equipment, semiconductor manufacturing, etc., the stainless steel material can meet the special requirements of these occasions. It can not only prevent cross-infection, but also avoid impurity pollution, so it can contribute to energy conservation and environmental protection.

[0127] In this embodiment, the protective housing 1 is made of aluminum alloy material to improve corrosion resistance and abrasion resistance.

[0128] In this solution, the main body of the travel sensor is tightly wrapped by a strong protective housing 1 to ensure that the internal components are fully protected and at the same time provide stable support;

[0129] The protective housing 1 can effectively isolate the internal components from the external environment, prevent impurities such as external dust, moisture, and oil stains from invading, reduce the damage to the internal electronic components and internal circuits of the travel sensor, and ensure the stability and accuracy of the sensor;

[0130] The travel sensor is often subject to mechanical shocks and vibrations during operation. Using the protective housing 1 can effectively avoid mechanical damage. At the same time, the protective housing 1 made of high-strength material and with excellent impact resistance can be used for a long time, improving the durability of the travel sensor;

[0131] The protective housing 1 of the travel sensor can avoid misoperation or human damage, thereby increasing the service life of the equipment and reducing the electrical faults caused thereby;

[0132] The protective housing 1 can provide additional protection and support for the internal components when maintaining and servicing the travel sensor, and at the same time facilitate the inspection and replacement of the internal components of the travel sensor;

[0133] The strong protective housing 1 not only helps to improve the accuracy and reliability of the travel sensor, but also can avoid the occurrence of accidents, thereby improving the safety of the equipment and operators.

[0134] In the embodiment of the present invention, the protective housing 1 is made of aluminum alloy material. The aluminum alloy material has good corrosion resistance and is suitable for use in harsh environments such as humidity, acid, and alkali. Therefore, choosing aluminum alloy as the protective housing 1 of the travel sensor can extend the service life of the sensor;

[0135] The aluminum alloy material has high strength and wear resistance. Using aluminum alloy to make the protective housing 1 can enable the travel sensor to obtain higher compressive capacity and protection ability, as well as a more durable surface performance;

[0136] The aluminum alloy material has good thermal conductivity, which helps the sensor to dissipate heat, and can ensure that the sensor will not overheat during operation, resulting in damage to internal components or affecting the measurement accuracy;

[0137] The aluminum alloy material is easy to process and manufacture, has flexible dimensional design and processing capabilities, can meet the requirements of different sizes and shapes of travel sensors, and can also reduce costs and time costs;

[0138] Compared with other high-strength materials such as stainless steel, the specific gravity of aluminum alloy materials is relatively light. They are lightweight and have a low density, which can meet the design requirements of high strength and light weight, ensuring that the sensor is portable, flexible, and also convenient for transportation and handling.

[0139] In summary, using aluminum alloy material for the protective housing 1 can improve the accuracy, reliability, and safety of the travel sensor. In addition, the advantages of aluminum alloy materials such as corrosion resistance, high strength, wear resistance, good thermal conductivity, and ease of manufacturing and processing make the protective housing 1 have higher applicability and can be applied to travel sensors in different industries, different working conditions, different sizes, and shapes. In short, using aluminum alloy material as the protective housing 1 of the travel sensor can make the sensor more durable, reliable, more accurate, and more flexible to adapt to various industrial and environmental applications.

[0140] In this embodiment, a sealing silicone pad 6 for filling the gap at the connection between the aviation socket and the sensor is provided inside the protective housing 1. A sealing rubber ring 7 for enhancing the combination of the aviation plug and the aviation socket is provided inside the protective housing 1. A pin hole 8 is provided on the surface of the protective housing 1. A guard plate 9 for preventing external dust and rain from entering is provided outside the pin hole 8. The guard plate 9 is made of a corrosion-resistant and high-strength metal material. The guard plate 9 is made of a corrosion-resistant metal material. The guard plate 9 is arc-shaped. The shape of the guard plate 9 is adapted to the surface of the protective housing 1, and the guard plate 9 wraps the surface of the protective housing 1. Multiple groups of through holes are provided on the surface of the guard plate 9 and penetrate through the guard plate 9. The aperture of the through holes is the same as the aperture of the pin hole 8. The pin can pass through the through holes and the pin hole 8 to fix the position of the guard plate 9.

[0141] In the application scenario of the travel sensor, the environment along the railway is complex. A large amount of dust will be rolled up when the freight train is running. During the loading and unloading process of the freight train, various dusts, particles and other impurities will also be raised, which are very likely to enter the sensor internal and affect its performance.

[0142] In this solution, a sealing silicone pad 6 is used for combination between the aviation plug base and the protective housing 1. The sealing silicone pad 6 has good elasticity, softness, and plasticity. During installation, it can adaptively deform according to the gaps between the sensor components and the shape of the components, tightly fill the gaps, and form an efficient dust-proof barrier. At the same time, the sealing silicone pad is a wear-resistant silicone material. During the long-term use of the sensor, even if it is subjected to a certain degree of extrusion or friction caused by the relative movement of the components, it is not easy to be damaged and can continuously and stably maintain its sealing performance.

[0143] For the interface part of the sensor, an IP67 aviation plug is used in the present invention. At the connection between the aviation socket and the sensor, while using a gasket, anaerobic glue is also used for sealing and locking to prevent the intrusion of external dust and rain. At the same time, the aviation plug itself has a sturdy shell with a tightly designed structure, which can effectively block dust. When the IP67 aviation plug is connected to the aviation socket, a special locking structure is used to achieve a tight fit, reduce gaps, and prevent dust from entering through the connection part. A high-precision processing technology is adopted between the pins and sockets of the aviation plug to ensure tight contact.

[0144] Among them, the locking structure adopts a threaded locking structure. The threaded locking structure usually includes the threads on the plug and the threads on the aviation socket that fit with each other. By rotating the aviation plug, a tight connection between the plug and the aviation socket can be achieved. The threaded locking mechanism has the advantages of good mechanical mechanical properties and high safety.

[0145] At the same time, a wedge-shaped locking structure can also be adopted. The wedge-shaped locking structure includes a wedge-shaped member on the plug and a corresponding member on the aviation socket. Through the friction between the plug and the aviation socket and the tight fit of the wedge-shaped structure, easy insertion and firm locking can be achieved.

[0146] In the present invention, the guard plate 9 outside the pin shaft hole 8 covers the outside of the pin shaft hole 8, and its shape is adapted to the surrounding structure of the pin shaft hole 8. It is firmly installed by means of screw fixation, effectively blocking the possibility of dust entering through this potential channel of the pin shaft hole 8.
