Description

Technical Field

[0001] This invention relates to the field of railway locomotive technology, and in particular to a method for monitoring the cylinder jamming and cylinder installation status. Background Technology

[0002] Railway locomotives are equipped with main air cylinders, brake air cylinders, and air spring air cylinders, such as those found in trains and subway cars. Air cylinders are used to supply air for vehicle braking and other auxiliary functions during the working intervals of the air compressor. Air cylinders are primarily fixed in place using air cylinder clips.

[0003] In related technologies, the air cylinder clamp only provides the function of fixing the air cylinder, but cannot monitor the installation status of the air cylinder. To obtain information about the installation status of the air cylinder, it is necessary to stop the vehicle, remove the air cylinder for inspection, and the inspection efficiency is low. When the vehicle is running, if the air cylinder installation becomes loose or the clamp is damaged or broken, the vehicle cannot detect it in time, which poses a great threat to driving safety. Summary of the Invention

[0004] The purpose of this invention is to provide a method for monitoring the cylinder clamping and cylinder installation status. This method can monitor the installation status of the cylinder in real time, ensuring the driving safety of the locomotive.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On one hand, a cylinder clamping device is provided, including a clamping body and a monitoring device. The clamping body is used to clamp or release the cylinder. The monitoring device includes a detection module and a data acquisition module. The detection module includes a housing, a detection element, an elastic element, and a push rod. The detection element and the elastic element are disposed in the housing. The housing is fixedly connected to the clamping body. One end of the elastic element is fixedly connected to the inner wall of the housing, and the other end is fixedly connected to the first end of the push rod. A through hole is provided on the housing. The second end of the push rod passes through the through hole and is used to abut against the outer wall of the cylinder. The push rod slides relative to the wall of the through hole along its own length direction. The data acquisition module is electrically connected to the detection element to form a detection circuit. The data acquisition module can acquire the current signal of the detection circuit. The elastic element can extend and retract along the length direction of the push rod so that the current signal of the detection circuit changes.

[0007] Preferably, the detection element includes a resistor and a slider, the slider being slidably connected to the resistor and fixedly connected to the push rod, one of the positive and negative terminals of the data acquisition module being circuitally connected to one end of the resistor, and the other of the positive and negative terminals of the data acquisition module being circuitally connected to the slider.

[0008] Preferably, the monitoring device also includes an alarm module, which is communicatively connected to the data acquisition module and is used to issue an alarm.

[0009] Preferably, the air cylinder cartridge also includes a fixing seat, which is fixedly connected to the cartridge body. The housing is fixedly connected to the fixing seat, and the fixing seat has a clearance hole. The push rod passes through the through hole, the clearance hole and the cartridge body in sequence.

[0010] Preferably, the cartridge body includes a first clamp and a second clamp, with one end of the first clamp and the second clamp fixedly connected and the other end detachably connected, so that the first clamp and the second clamp can tighten or loosen the air cylinder, and the fixing seat is fixedly connected to one of the first clamp and the second clamp.

[0011] Preferably, the air cylinder clamp also includes a fastening structure, which includes a locking bolt and a locking nut, as well as two locking parts respectively disposed at one end of the first clamp and the second clamp that are detachably connected. The locking bolt passes through the two locking parts in sequence, and the locking nut is screwed onto the locking bolt so that the two locking parts of the first clamp and the second clamp are close to or far from each other.

[0012] Preferably, the cylinder cartridge further includes a protective layer disposed on the contact surface of the cartridge body for contacting the cylinder; and / or, the cylinder cartridge further includes a connecting seat fixedly connected to the cartridge body for connection with the locomotive.

[0013] On the other hand, a method for monitoring the installation status of an air cylinder is provided. This method is applied to the air cylinder cartridge of any of the above-mentioned technical solutions. The air cylinder installation status monitoring method includes:

[0014] Hold the air cylinder tightly against the cassette body, and have the push rod abut against the outer wall of the air cylinder;

[0015] The current signal of the detection circuit is acquired in real time through the data acquisition module;

[0016] The installation status of the air cylinder is determined based on the current signal acquired in real time from the detection circuit. The installation status of the air cylinder includes whether it is installed in place, loose, or detached.

[0017] Preferably, the step of determining the installation status of the air cylinder based on the current signal acquired by the real-time acquisition and detection circuit includes:

[0018] If the current signal of the detection circuit is less than or equal to the first current threshold and greater than or equal to the second current threshold, then the air cylinder is installed in place.

[0019] If the current signal of the detection circuit is less than the second current threshold and greater than or equal to the third current threshold, then the air cylinder installation status is loose.

[0020] If the current signal of the detection circuit is less than the third current threshold and greater than or equal to the fourth current threshold, then the air cylinder installation status is detached.

[0021] The first current threshold, the second current threshold, the third current threshold, and the fourth current threshold are set from largest to smallest.

[0022] As a preferred embodiment, the method for monitoring the installation status of the air cylinder also includes:

[0023] If the current signal of the detection circuit is greater than the first current threshold or less than the fourth current threshold, the monitoring device is faulty.

[0024] The monitoring device was inspected and repaired.

[0025] The beneficial effects of this invention are as follows:

[0026] A method for monitoring the installation status of an air cylinder is provided. The air cylinder clamping tape includes a clamping tape body and a monitoring device. The clamping tape body is used to clamp or release the air cylinder. The monitoring device includes a detection module and a data acquisition module. The detection module includes a housing, a detection element, an elastic element, and a push rod. The detection element and the elastic element are disposed in the housing. The housing is fixedly connected to the clamping tape body. One end of the elastic element is fixedly connected to the inner wall of the housing, and the other end is fixedly connected to the first end of the push rod. A through hole is provided on the housing. The second end of the push rod passes through the through hole and is used to abut against the outer wall of the air cylinder. The push rod slides relative to the wall of the through hole along its own length direction. The data acquisition module is electrically connected to the detection element to form a detection circuit. The data acquisition module can acquire the current signal of the detection circuit. The elastic element can extend and retract along the length direction of the push rod to change the current signal of the detection circuit.

[0027] The extension and retraction of the elastic element drives the push rod to move, thereby changing the current signal of the detection circuit. When the cassette body grips the air cylinder, the outer wall of the air cylinder applies reverse pressure to the push rod, compressing the elastic element and causing the push rod to move relative to the housing, triggering a change in the state of the detection element, which is ultimately fed back through a current signal. When the cassette releases, the elastic element resets, pushing the push rod to extend, and the current signal switches synchronously. This design, which converts mechanical displacement into electrical signal changes, directly binds the mechanical action of the cassette to the collectable electrical signal, ensuring that the monitoring results correspond one-to-one with the actual gripping state of the air cylinder. This allows for real-time monitoring of the air cylinder's installation status. When the air cylinder installation becomes loose or the cassette is damaged or broken, the driver can promptly detect the problem and take appropriate action, improving driving safety.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0040] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0043] On the one hand, please refer to Figures 1 to 6 This embodiment provides a cylinder clamping device, including a clamping body 1 and a monitoring device 2. The clamping body 1 is used to clamp or release the cylinder 7. The monitoring device 2 includes a detection module 21 and a data acquisition module 22. The detection module 21 includes a housing 211, a detection element 212, an elastic element 213, and a push rod 214. The detection element 212 and the elastic element 213 are disposed in the housing 211. The housing 211 is fixedly connected to the clamping body 1. One end of the elastic element 213 is fixedly connected to the inner wall of the housing 211, and the other end is fixedly connected to the first end of the push rod 214. A through hole is provided on the housing 211. The second end of the push rod 214 passes through the through hole and is used to abut against the outer wall of the cylinder 7. The push rod 214 slides relative to the hole wall of the through hole along its own length direction. The data acquisition module 22 is electrically connected to the detection element 212 to form a detection circuit. The data acquisition module 22 can acquire the current signal of the detection circuit. The elastic element 213 can extend and retract along the length direction of the push rod 214 so that the current signal of the detection circuit changes. Specifically, the elastic element 213 is a compression spring. In other embodiments, the elastic element 213 may also be a spring sheet or the like.

[0044] This design, through the extension and retraction of the elastic element 213, drives the push rod 214 to shift, thereby altering the current signal of the detection circuit. When the cassette body 1 grips the air cylinder 7, the outer wall of the air cylinder 7 applies reverse pressure to the push rod 214, compressing the elastic element 213 and causing the push rod 214 to shift relative to the housing 211, triggering a state change in the detection element 212, which is ultimately fed back through a current signal. When the cassette is released, the elastic element 213 resets, pushing the push rod 214 to extend, and the current signal switches synchronously. This design, which converts mechanical displacement into electrical signal changes, directly binds the mechanical action of the cassette to the collectable electrical signals, ensuring that the monitoring results correspond one-to-one with the actual gripping state of the air cylinder 7. This allows for real-time monitoring of the installation status of the air cylinder 7. If the air cylinder 7 becomes loose or the cassette is damaged or broken, the driver can promptly detect the problem and take appropriate action, improving driving safety.

[0045] In this embodiment, the detection element 212 is a sliding rheostat.

[0046] Specifically, please refer to Figure 2 The detection component 212 includes a resistor and a slider. The slider is slidably connected to the resistor and fixedly connected to the push rod 214. One of the positive and negative terminals of the data acquisition module 22 is connected to one end of the resistor, and the other is connected to the slider. By pushing the slider relative to the resistor with the push rod 214, the resistance value of the sliding rheostat is changed, thereby changing the current signal of the detection circuit. The signal responds in real time, ensuring that the driver can promptly detect any loosening, jamming, or breakage of the air cylinder 7.

[0047] In other embodiments, the detection element 212 may also be a proximity switch, etc.

[0048] Optionally, the monitoring device 2 also includes an alarm module, which is communicatively connected to the data acquisition module 22 and is used to issue an alarm. With this configuration, the alarm module can promptly sound an alarm when loosening or detachment occurs, preventing situations where the air cylinder 7 is loose or detached without a driver present, thus ensuring driving safety.

[0049] Specifically, the alarm module includes indicator lights, a display screen, and an alarm bell. The indicator lights are used to display different lights according to the installation status of the air cylinder 7. The display screen is used to display the installation status of the air cylinder 7. The alarm bell is used to sound an alarm when the air cylinder 7 becomes loose or falls off.

[0050] Alternatively, please refer to Figure 3 and Figure 4The air cylinder cartridge also includes a fixing seat 3, which is fixedly connected to the cartridge body 1. The housing 211 is fixedly connected to the fixing seat 3. The fixing seat 3 has a clearance hole 31. The push rod 214 passes through the through hole, the clearance hole 31 and the cartridge body 1 in sequence. Specifically, the housing 211 of the detection module 21 is bolted to the fixing seat 3.

[0051] This design serves two purposes. First, since the cartridge body 1 is a strip-shaped structure, directly fixing the housing 211 might cause it to tilt or shift due to slight deformation. By setting the fixing seat 3, a stable rigid support can be provided for the housing 211, preventing it from twisting or deforming due to deformation or vibration of the cartridge body 1. This ensures that the sliding direction of the push rod 214 is always perpendicular to the tangent of the outer wall of the air cylinder 7, avoiding problems such as poor contact between the slider and the resistor, and jamming of the push rod 214. Second, the through hole of the housing 211 provides the first guide for the push rod 214, and the clearance hole 31 of the fixing seat 3 provides the second guide for the push rod 214. The coaxial design of the two guide structures can strictly limit the push rod 214 to slide only along its own length direction, preventing the push rod 214 from deviating or swinging during the sliding process, and ensuring stable changes in the current signal.

[0052] Alternatively, please refer to Figure 1 and Figure 5 The cartridge body 1 includes a first clamp 11 and a second clamp 12. One end of the first clamp 11 and the second clamp 12 are fixedly connected, and the other end is detachably connected, so that the first clamp 11 and the second clamp 12 can tighten or loosen the air cylinder 7. The fixing seat 3 is fixedly connected to one of the first clamp 11 and the second clamp 12. With this configuration, the first clamp 11 and the second clamp 12 adopt an openable structure of "one end fixed and the other end detachable". Compared with the integral cartridge or the structure that requires disassembly at both ends, the operation is more efficient: during installation, only the detachable end needs to be opened, and the two clamps are wrapped around the air cylinder 7 and locked; during disassembly, the cartridge can be quickly removed by loosening the detachable end without disassembling the whole cartridge. This greatly simplifies the installation, maintenance and replacement process of the air cylinder 7, and is especially suitable for scenarios where the installation space of the air cylinder 7 is small, reducing the difficulty of operation.

[0053] Further, please refer to Figure 3 and Figure 5The air cylinder clamp also includes a fastening structure, which includes a locking bolt 4 and a locking nut 5, as well as two locking parts 13 respectively provided at one end of the first clamp 11 and the second clamp 12 that are detachably connected. The locking bolt 4 passes through the two locking parts 13 in sequence, and the locking nut 5 is screwed onto the locking bolt 4 so that the two locking parts 13 of the first clamp 11 and the second clamp 12 are close to or far away from each other. This design allows for several advantages. First, by rotating the locking nut 5, the two locking parts 13 can be driven closer together, causing the first clamp 11 and the second clamp 12 to surround the air cylinder 7 and generate a uniform clamping force. Simultaneously, by tightening the locking bolt 4, the clamping force can be adjusted, preventing the air cylinder 7 from loosening due to insufficient clamping force or deforming of the outer wall of the air cylinder 7 due to excessive clamping force. Second, by adjusting the position of the locking nut 5 on the bolt, the distance between the two locking parts 13 can be changed, thus adapting to air cylinders 7 of different diameters. Compared to fixed-size cartridges, this adjustable design eliminates the need for separate molds for specific air cylinders 7 on the cartridge body 1. Only the length of the clamps or the bolt specifications need to be adjusted to adapt to various scenarios, significantly improving the product's versatility and reducing design and production costs.

[0054] In other embodiments, the fastening structure may also be a snap-fit ​​structure.

[0055] Furthermore, the cylinder clamp also includes a protective layer, which is disposed on the contact surface of the clamp body 1 that contacts the cylinder 7. Specifically, the protective layer is made of rubber. By having the rubber protective layer contact the outer wall of the cylinder 7, the friction between the clamp body 1 and the outer wall of the cylinder 7 is increased. When the clamp body 1 grips the cylinder 7, it prevents the cylinder 7 from shifting and improves the reliability of the cylinder clamp.

[0056] Optionally, the cylinder clamp also includes a connecting seat 6, which is fixedly connected to the clamp body 1 and is used for connection with the locomotive. Specifically, the connecting seat 6 is welded to the clamp body 1, and the connection with the locomotive can be achieved through standardized fasteners such as bolts and pins. This configuration increases the contact area between the cylinder clamp and the locomotive, distributing the fixing stress evenly across the locomotive mounting surface and preventing excessive local stress that could damage the locomotive mounting point. It also ensures that the cylinder 7 forms a stable connection with the locomotive through the combination of the clamp body 1 and the connecting seat 6, avoiding the safety risks of displacement or detachment of the cylinder 7.

[0057] On the other hand, a method for monitoring the installation status of an air cylinder is provided. This method is applied to the aforementioned air cylinder cartridge and includes:

[0058] The air cylinder 7 is held tightly against the cassette body 1, and the push rod 214 abuts against the outer wall of the air cylinder 7;

[0059] The current signal of the detection circuit is acquired in real time by the data acquisition module 22;

[0060] The installation status of the air cylinder is determined based on the current signal acquired in real time from the detection circuit. The installation status of the air cylinder includes whether it is installed in place, loose, or detached.

[0061] Optionally, the steps for determining the installation status of the air cylinder based on the real-time acquisition and detection circuit current signal include:

[0062] If the current signal of the detection circuit is less than or equal to the first current threshold and greater than or equal to the second current threshold, then the air cylinder is installed in place.

[0063] If the current signal of the detection circuit is less than the second current threshold and greater than or equal to the third current threshold, then the air cylinder installation status is loose.

[0064] If the current signal of the detection circuit is less than the third current threshold and greater than or equal to the fourth current threshold, then the air cylinder installation status is detached.

[0065] The first current threshold, the second current threshold, the third current threshold, and the fourth current threshold are set from largest to smallest.

[0066] In this embodiment, the first current threshold is 20mA, the second current threshold is 14mA, the third current threshold is 12mA, and the fourth current threshold is 4mA.

[0067] Specifically, the data acquisition module 22 can detect a current range of 4mA-20mA. When the push rod 214 is fully extended from the monitoring device 2, its length is 20mm, and the current acquired by the data acquisition device is 4mA. When the air cylinder 7 is fully installed, the push rod 214 extends to a length of 7.5mm, and the current acquired by the data acquisition device is 14mA. The judgment logic of the monitoring device 2 is as follows: when the detected current signal is 20mA ≥ A ≥ 14mA, it is determined that the installation is in place; when the monitoring device 2 detects a current signal of 14mA > A ≥ 12mA, it is determined that the air cylinder 7 is loose, and the air cylinder installation status information is displayed on the screen, prompting the driver to check for loose installation and tighten the air cylinder clamp; when the detected current signal is 12mA > A ≥ 4mA, it is determined that the air cylinder has fallen off, and the air cylinder installation status information is displayed on the screen, prompting the driver to check for falling off and stop the vehicle to handle the problem.

[0068] Optionally, the method for monitoring the installation status of the air cylinder also includes:

[0069] If the current signal of the detection circuit is greater than the first current threshold or less than the fourth current threshold, then the monitoring device 2 is faulty.

[0070] The monitoring device 2 was inspected and repaired.

[0071] Specifically, in this embodiment, when the detected current A > 20mA or the detected current A < 4mA, it is determined that the monitoring device 2 is faulty, and the fault information of the monitoring device 2 is displayed on the screen, indicating that the monitoring device 2 needs to be repaired.

[0072] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
