Description

Technical Field

[0001] This invention belongs to the field of locomotive and rolling stock safety technology, and specifically relates to a monitoring and alarm device for the absence of anti-slip rails on railway locomotives. Background Technology

[0002] During railway transportation, locomotives and rolling stock often need to stay for extended periods at specific locations such as dedicated lines and marshalling yards. Due to the gradient of railway lines, even when the locomotives and rolling stock are stationary, they may slip due to gravity. Wheel slippers can effectively prevent wheel movement in these scenarios, ensuring the safety of vehicles during maintenance, loading, and unloading operations. Currently, when not in use, wheel slippers should be reliably placed in wheel slipper holders. While manual inspection to check the condition of the wheel slippers is also used when the locomotive is stopped, this method carries the risk of wheel slippers being left on the rails due to missed inspections.

[0003] A search revealed the following patent application, CN121469658A, published on February 6, 2026, entitled "An Intelligent Management System Based on Anti-Slip Iron Shoes." The system includes an iron shoe body, an intelligent detection module, and an antenna compartment. The iron shoe body comprises a shoe plate, a first baffle, a second baffle, a spring pressure plate, and a tread. The first baffle is vertically fixed to one side of the shoe plate, and the second baffle is vertically fixed to the other side. The bottom of both the first and second baffles has holes for mounting iron forks, allowing the anti-slip iron shoe to move based on the forks. The first side of the spring pressure plate is rotatably connected between the first and second baffles, and the tread is positioned above the first and second baffles.

[0004] However, the above embodiments still have the following drawbacks:

[0005] The above embodiments cannot detect the position of the track shoe in real time, which may lead to the risk of the track shoe being left on the rails, thereby reducing the safety level of locomotive operation. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a monitoring and alarm device for monitoring and alarming the absence of anti-slip track shoes on railway locomotives, comprising a detection and storage box. The top opening of the detection and storage box is provided with a storage slot, and two sets of single-sided slots are symmetrically provided in the storage slot. Two sets of storage units are symmetrically arranged in the two sets of single-sided slots.

[0007] The storage unit includes an angle adjustment mechanism. The main body of the angle adjustment mechanism is inclined. A detection and limiting mechanism is provided directly below the angle adjustment mechanism. The detection and limiting mechanism includes two sets of symmetrical side plates. The side wall of the side plate near the partition is set as a slope. Several sets of first locking rods are arranged at equal intervals at the edge of the slope. Several sets of second locking rods, the same number as the first locking rods, are arranged at equal intervals on the side wall of the side plate away from the slope. Each of the first and second locking rods is equipped with a set of first pressure sensors.

[0008] A base plate is located directly below the gap between the bottommost set of first and second clamps, and several sets of second pressure sensors are arranged at equal intervals on the base plate.

[0009] Furthermore, a partition is provided between the two sets of single-sided slots; a set of heat dissipation vents is provided on the side wall near the top of each set of storage slots, and a fan is connected to one end of the storage slot; several sets of indicator lights, the same number as the number of storage slots, are fixedly installed on the outer wall of the detection storage box.

[0010] Furthermore, the angle adjustment mechanism includes a lower slide plate, which is inclined and its top is fixedly connected to the top edge of a corresponding set of single-sided grooves away from the partition; the bottom width of the lower slide plate is smaller than the top width, and two sets of side adjustment plates are symmetrically arranged on both sides of the lower slide plate.

[0011] Furthermore, on the top of the lower slide plate and on the two opposite side walls of the two sets of side adjustment plates, there are several sets of first ball grooves arranged at equal intervals. A first ball is rotatably connected in the first ball groove. The diameter of the first ball is smaller than that of the first ball. The top of the first ball extends to the outside of the first ball groove.

[0012] Furthermore, two sets of tilt adjustment mechanisms are symmetrically arranged at the bottom two sides of the angle adjustment mechanism. The tilt adjustment mechanism includes a top plate, and a suspended column is fixedly installed at the bottom of the top plate in the vertical direction. Two sets of second ball grooves are symmetrically opened on the opposite side walls of the two sets of suspended columns. A second ball is rotatably connected in the second ball groove. The diameter of the second ball is smaller than the diameter of the second ball groove. The top of the second ball extends to the outside of the second ball groove.

[0013] Furthermore, a ventilation window is provided at the center of the side plate, and several sets of support brackets, the same number as the number of second pressure sensors, are arranged at equal intervals on the bottom plate. Each set of second pressure sensors is fixedly installed on the corresponding set of support brackets.

[0014] Furthermore, a set of vibration plates is fixedly installed at the bottom of both sets of side plates, a damping shock absorber is fixedly installed at the bottom of the vibration plate, a support plate is fixedly installed at the bottom of the damping shock absorber, and the edge of the support plate is installed on the inner wall of the storage groove.

[0015] Furthermore, two sets of side hard brushes are fixedly installed between the first and second clamps in the uppermost group. The side hard brushes have a crescent-shaped cross-section when viewed from the side, and the two sets of side hard brushes are arranged symmetrically to each other.

[0016] Furthermore, a drying chamber is provided at the bottom of the detection and storage box cavity, and a drying unit is fixedly installed in the drying chamber; the drying unit includes a hot air drying device and several sets of blowers, the number of blowers being the same as the number of storage slots, the output end of each set of blowers being located directly below the corresponding set of storage slots, and the top of each set of blowers being connected to a set of air concentrators, the cavity of each set of air concentrators being connected to the output end of the hot air drying device; a spiral groove is provided along a spiral path on the side wall of each set of air concentrators.

[0017] Furthermore, a dust collection unit is movably installed at the junction of the drying chamber and each set of storage slots; the dust collection unit includes two sets of slide rails, which are symmetrically arranged with the central axis in the width direction of the storage slot as the center, and a dust collection box is movably installed between the two sets of slide rails; a sealing pull plate is movably installed on the side wall of the detection storage box, and the height of the sealing pull plate is the same as that of the dust collection box.

[0018] The beneficial effects of this invention are:

[0019] 1. Due to the triangular shape of the iron shoe, the first clamps of each group are arranged at equal intervals along the slope, and combined with the second clamps arranged vertically, as well as the bottom support brackets that support the iron shoe from the bottom. This ensures that the surface of the iron shoe is not unable to dissipate heat or evaporate moisture due to complete covering, while also ensuring that the force is evenly distributed in each position. At the same time, each group of first and second pressure sensors can also sense the pressure. Using multi-form detection and early warning, it can simultaneously identify three states of the iron shoe: correct placement, misplacement, and not in place. This not only reduces the safety hazards caused by not removing the iron shoe before the locomotive is moved, but also prevents the iron shoe from shaking or falling off during subsequent transfer. This not only enriches the functionality of the device, but also improves the level of locomotive operation safety.

[0020] 2. When mud or moisture adheres to the surface of the metal shoe, first turn on the blower. The blower's airflow acts vertically upwards on the shoe. Then, the hot air drying device heats the airflow passing through the air-collecting duct, and combined with the spiral grooves of the spiral path, the hot air is concentrated rapidly on the shoe in a vortex, increasing the drying effect and evaporating moisture from the mud and reducing the mud's adhesion. Then, the dust collection box is installed, and the vibration motor is turned on to shake off impurities from the shoe surface, which are fixed to the detection and limit mechanism. This achieves an automatic cleaning effect and improves the protection of the metal shoe.

[0021] 3. Since the working environment for the metal shoes is on outdoor railway tracks, their surface is easily contaminated with dust, stains, or mud. Two sets of side hard brushes utilize sliding friction during the shoe's descent to initially clean these impurities. Furthermore, the crescent-shaped structure of the side hard brushes increases the contact area with the shoe's surface, making them suitable for any size metal shoe and thus improving compatibility.

[0022] 4. Place the two sets of metal shoes on two symmetrically arranged sliding plates. The shoes slide along the inclined angle of the sliding plate and under the action of the first set of rolling balls on its surface. As the sliding plate gradually narrows, the shoes adjust their angle under the action of the first set of rolling balls on the side adjustment plates, ensuring a vertical drop into the detection and limiting mechanism below. After detaching from the sliding plate, the shoes roll and rub against the second rolling balls on both sides, correcting their horizontal angle and preventing tilting upon landing at the detection and limiting mechanism. This achieves automatic adjustment and automatic limiting, eliminating the need for manual placement of the shoes, shortening storage time, and improving its auxiliary effect on the detection process.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention provides a monitoring and alarm device for the absence of anti-slip rails on railway locomotives, exemplarily, such as... Figure 1 and Figure 2The device includes a testing and storage box 100, which has a storage slot 110 at the top opening. The storage slot 110 has two sets of single-sided slots 111 symmetrically arranged around its own central axis, and a partition is provided between the two sets of single-sided slots 111.

[0038] Specifically, each of the storage slots 110 has a set of heat dissipation vents 120 on the side wall near the top, and the heat dissipation vents 120 are connected to a fan 121 at one end of the storage slot 110.

[0039] Specifically, the outer wall of the detection storage box 100 is fixedly equipped with several sets of indicator lights 130, the same number as the storage slots 110. The indicator lights 130 are preferably red, yellow, and green.

[0040] For example, each set of storage slots 110 is fixedly installed with a set of detection and storage modules. Each set of detection and storage modules includes two sets of storage units 200, which are symmetrically arranged in the two sets of single-sided slots 111. The storage units 200 are used to store the iron shoes and monitor their storage status and whether they are placed correctly.

[0041] For example, the bottom of the detection storage box 100 has a drying chamber, and a drying unit 400 is fixedly installed in the drying chamber. The output end of the drying unit 400 is connected to the cavity of each set of storage slots 110. The drying unit 400 is used to dry the moisture on the surface of the iron shoe to avoid oxidation.

[0042] For example, a set of dust collection units 300 are movably installed at the junction of the drying chamber and each set of storage slots 110. The dust collection units 300 are used to collect dust and impurities shaken off the surface of the iron shoes.

[0043] For example, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the storage unit 200 includes an angle adjustment mechanism, which includes a lower sliding plate 210. The lower sliding plate 210 is inclined, and its top is fixedly connected to the top edge of a corresponding set of single-sided grooves 111 on the side away from the partition. The bottom width of the lower sliding plate 210 is smaller than its top width, and two sets of side adjustment plates 211 are symmetrically arranged on both sides of the lower sliding plate 210. On the top of the lower sliding plate 210 and the opposite side walls of the two sets of side adjustment plates 211, several sets of first ball grooves are arranged at equal intervals. A first ball 212 is rotatably connected in the first ball groove, and the diameter of the first ball 212 is smaller than that of the first ball. The top of the first ball 212 extends outside the first ball groove.

[0044] For example, two sets of tilt adjustment mechanisms 220 are symmetrically arranged on both sides of the bottom edge of the sliding plate 210. Each tilt adjustment mechanism 220 includes a top plate 221. A suspended column 222 is fixedly installed vertically at the bottom of the top plate 221. Two sets of second ball grooves 223 are symmetrically opened on the opposite side walls of the two sets of suspended columns 222. A second ball 224 is rotatably connected in the second ball groove 223. The diameter of the second ball 224 is smaller than the diameter of the second ball groove 223. The top of the second ball 224 extends outside the second ball groove 223.

[0045] For example, a detection and limiting mechanism is provided directly below the bottom of the sliding plate 210. The detection and limiting mechanism includes two sets of symmetrically arranged side plates 230, and a ventilation window 232 is provided at the center of each side plate 230. The side wall of the side plate 230 near the partition is set as a slope 231, and several sets of first locking rods 240 are arranged at equal intervals along the length of the slope 231. The side wall of the side plate 230 away from the slope 231 is arranged at equal intervals along the vertical direction, with the same number of sets of second locking rods 250 as the first locking rods 240. Each set of second locking rods 250 is at the same height as the corresponding set of first locking rods 240.

[0046] Specifically, a set of first pressure sensors 251 are fixedly installed on the opposite side walls of the first clamp 240 and the second clamp 250.

[0047] For example, a base plate 260 is provided directly below the gap between the lowest set of first clamping rods 240 and second clamping rods 250. Several sets of bottom support brackets 261 are arranged at equal intervals on the base plate 260, and a set of second pressure sensors 262 are fixedly installed on the top of each set of bottom support brackets 261.

[0048] For example, a set of vibration plates 280 are fixedly installed at the bottom of both sets of side plates 230. A damping shock absorber 281 is fixedly installed at the bottom of the vibration plate 280, and a support plate 282 is fixedly installed at the bottom of the damping shock absorber 281. The edge of the support plate 282 is installed on the inner wall of the storage groove 110. A vibration motor is fixedly installed on one set of vibration plates 280.

[0049] For example, two sets of side hard brushes 270 are fixedly installed between the uppermost set of first clamp rods 240 and second clamp rods 250. The side hard brushes 270 have a crescent-shaped cross-section when viewed from the side, and the central axis of the slide plate 210 below the two sets of side hard brushes 270 is centrally symmetrical.

[0050] First, two sets of metal shoes are placed on two symmetrically arranged sliding plates 210. This allows the shoes to slide down the inclined angle of the sliding plates 210 and under the action of the first rolling balls 212 on their surfaces. As the sliding plates 210 gradually narrow, the shoes also gradually adjust their angle under the action of the first rolling balls 212 on the side adjustment plates 211, facilitating a vertical drop from the sliding plates 210 into the detection and limiting mechanism below. After detaching from the sliding plates 210, the shoes roll and rub against the second rolling balls 224 on both sides, correcting the horizontal angle of the shoes and preventing tilting when they reach the detection and limiting mechanism. This achieves automatic adjustment and automatic limiting, eliminating the need for manual placement of the shoes, shortening storage time, and improving their auxiliary effect on the detection process.

[0051] Due to the triangular shape of the iron shoe, the first clamps 240 are arranged at equal intervals along the slope 231, and combined with the second clamps 250 arranged vertically, as well as the bottom support brackets 261 that support the iron shoe from the bottom, so that the surface of the iron shoe is not unable to dissipate heat or evaporate moisture due to being completely covered, while also ensuring that the force is evenly distributed at each position, and that each first pressure sensor 251 and second pressure sensor 262 can also sense the pressure.

[0052] When the metal shoe is correctly positioned, all sets of first pressure sensors 251 and second pressure sensors 262 will sense pressure, and the corresponding green indicator light 130 will illuminate. If the metal shoe is contaminated with mud or other impurities, preventing full angle adjustment via the angle adjustment mechanism, one or more sets of first pressure sensors 251 and second pressure sensors 262 will not sense pressure. This indicates the metal shoe is incorrectly positioned and not fully locked. In this case, the corresponding yellow indicator light 130 will illuminate, promptly reminding staff to make adjustments. This prevents the metal shoe from shaking or falling during subsequent transfers. When all first pressure sensors 251 and second pressure sensors 262 fail to sense pressure, it indicates the metal shoe has not been returned to its original position. In this case, the corresponding red indicator light 130 will illuminate, promptly alerting staff to any misplaced metal shoe. Furthermore, each set of storage slots 110 is divided into two sets of single-sided slots 111, and each set of single-sided slots is adjustable through a set of storage units 200, so that each set of iron shoes can be stored independently without being squeezed, deformed, or collided with each other. This improves the tidiness of the storage work.

[0053] Since the working environment for these metal shoes is outdoor railway tracks, their surfaces are easily contaminated with dust, stains, or mud. Two sets of side hard brushes 270 utilize sliding friction during the shoe's descent to initially clean these impurities. Furthermore, the crescent-shaped structure of the side hard brushes 270 increases their contact area with the shoe's surface, making them suitable for metal shoes of any size and thus improving compatibility.

[0054] Due to the triangular shape of the iron shoe, the first clamps 240 are arranged at equal intervals along the slope 231, and combined with the vertically arranged second clamps 250 and the bottom support brackets 261 supporting the iron shoe from the bottom, the iron shoe surface is not prevented from being unable to dissipate heat or evaporate moisture due to being completely covered, while also ensuring that the force is evenly distributed at each position. At the same time, each first pressure sensor 251 and second pressure sensor 262 can also sense the pressure. Using multi-form detection and early warning, the device can simultaneously identify three states: the iron shoe is placed correctly, the iron shoe is misplaced, and the iron shoe is not in place. This not only reduces the safety hazards caused by the iron shoe not being removed before the locomotive is moved, but also prevents the iron shoe from shaking or falling off during subsequent transfer. This not only enriches the functionality of the device, but also improves the safety level of locomotive operation.

[0055] For example, such as Figure 8 As shown, the dust collection unit 300 includes two sets of slide rails 310, which are symmetrically arranged around the central axis of the width direction of the storage groove 110, and a dust collection box 320 is movably installed between the two sets of slide rails 310. A sealing pull plate 330 is movably installed on the side wall of the detection storage box 100, and the height of the sealing pull plate 330 is the same as that of the dust collection box 320.

[0056] When the dust collection box 320 collects excessive impurities, simply open the sealing pull plate 330 and then directly remove the dust collection box 320 horizontally along the slide rail 310. Utilizing its detachable nature, it can be removed during the drying process and then reinstalled during subsequent vibration, making it flexible in operation and highly functional.

[0057] For example, such as Figure 9 and Figure 10 As shown, the drying unit 400 includes a hot air drying device 410 and several sets of blowers 420. The number of blowers 420 is the same as the number of storage tanks 110. The output end of each set of blowers 420 is located directly below the corresponding set of storage tanks 110, and the top of each set of blowers 420 is connected to a set of air concentrators 430. The cavity of each set of air concentrators 430 is connected to the output end of the hot air drying device 410. Spiral grooves 440 are formed along a spiral path on the side wall of each set of air concentrators 430.

[0058] When mud or moisture adheres to the surface of the metal shoe, the blower 420 is first turned on. The airflow from the blower 420 acts vertically upwards on the metal shoe. Then, the hot air drying device 410 heats the airflow passing through the air-collecting duct 430, and with the help of the spiral groove 440 with a spiral path, the hot air is quickly concentrated on the metal shoe in a vortex, increasing the drying effect and evaporating the moisture from the mud, reducing the adhesion of the mud. Then, the dust collection box 320 is installed, and the vibration motor is turned on to shake off the impurities on the surface of the metal shoe, which are fixed on the detection limit mechanism. This achieves an automatic cleaning effect and improves the protection of the metal shoe.

[0059] Furthermore, the alarm device also includes a status indicator, which is preferably located in the driver's cab at one or two ends and is connected to the alarm device body via a signal connection. A synchronous alarm light is also added to facilitate monitoring of the status of the wheel chock at any time.

[0060] Furthermore, the alarm device as a whole uses 220V AC power, while the status indicator uses 5V DC power.

[0061] The above embodiments have the following beneficial effects:

[0062] 1. Due to the triangular shape of the iron shoe, the first clamps 240 of each group are arranged at equal intervals along the slope 231, and combined with the second clamps 250 arranged vertically, and the bottom support brackets 261 supporting the iron shoe from the bottom, the iron shoe surface is not prevented from being unable to dissipate heat or evaporate moisture due to being completely covered, while also ensuring that the force is evenly distributed at each position. At the same time, each first pressure sensor 251 and second pressure sensor 262 can also sense the pressure. Using multi-form detection and early warning, the three states of the iron shoe can be identified simultaneously: correct placement, misplacement, and not in place. This not only reduces the safety hazards caused by not removing the iron shoe before the locomotive is moved, but also prevents the iron shoe from shaking or falling off during subsequent transfer. This not only enriches the functionality of the device, but also improves the safety level of locomotive operation.

[0063] 2. When mud or moisture adheres to the surface of the metal shoe, first turn on the blower 420. The airflow from the blower 420 acts vertically upwards on the metal shoe. Then, the hot air drying device 410 heats the airflow passing through the air concentrator 430. Combined with the spiral grooves 440 with a spiral path, the hot air is quickly concentrated on the metal shoe in a vortex, increasing the drying effect and evaporating moisture from the mud, reducing the mud's adsorption capacity. Then, the dust collection box 320 is installed, and the vibration motor is turned on to shake off impurities from the surface of the metal shoe, which are fixed to the detection limit mechanism. This achieves an automatic cleaning effect and improves the protection of the metal shoe.

[0064] 3. Since the working environment for the metal shoes is outdoor railway tracks, their surface is easily contaminated with dust, stains, or mud. Two sets of side hard brushes 270, through sliding friction, initially clean the impurities from the metal shoes as they fall. Furthermore, the crescent-shaped structure of the side hard brushes 270 increases their contact area with the metal shoe surface, making them suitable for metal shoes of any size and thus improving compatibility.

[0065] 4. Place the two sets of metal shoes on two symmetrically arranged sliding plates 210, allowing the shoes to slide down the inclined angle of the sliding plates 210 and under the action of the first rolling balls 212 on their surface. As the sliding plates 210 gradually narrow, the metal shoes will also gradually adjust their angle under the action of the first rolling balls 212 on the side adjustment plates 211, facilitating a vertical drop from the sliding plates 210 into the detection limiting mechanism below. After detaching from the sliding plates 210, they roll and rub against the second rolling balls 224 on both sides, correcting the horizontal angle of the metal shoes and preventing them from tilting when they reach the detection limiting mechanism. This achieves an automatic adjustment and automatic limiting function, eliminating the need for staff to manually place the metal shoes, shortening storage time, and improving its auxiliary effect on the detection work.

[0066] 5. Each set of storage slots 110 is divided into two sets of single-sided slots 111, and each set of single-sided slots is adjustable through a set of storage units 200, so that each set of iron shoes can be stored independently without being squeezed, deformed or collided with each other. This improves the tidiness of the storage work.

[0067] 6. When the dust collection box 320 collects too much impurities, simply open the sealing pull plate 330 and then directly remove the dust collection box 320 horizontally along the slide rail 310. Taking advantage of its detachable nature, it can be removed during the drying process and then installed during subsequent vibration. The operation is flexible and highly functional.

[0068] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
