Abstract

This application provides a rail vehicle air storage cylinder and a rail vehicle, including: a boom that can extend and retract axially and is fixed; an opening and closing assembly for opening and locking the air cylinder drain valve with a triangular lock and / or a four-corner lock; and a rotary drive assembly, one end connected to the boom and the other end connected to the opening and closing assembly, for driving the opening and closing assembly to rotate and open or close the triangular lock and / or the four-corner lock. This application mounts the opening and closing assembly on the boom, which is used to open and lock the triangular lock and / or the four-corner lock of the air cylinder drain valve. The boom can extend and retract axially and is fixed. The axial extension and retraction of the boom sends the opening and closing assembly into the track, and the rotary drive assembly drives the opening and closing assembly to rotate, thus opening and closing the air cylinder drain valve. This eliminates the need for operators to crawl into the track or skirt support for operation, reducing manual operation costs and labor intensity, and improving the operating efficiency of the air cylinder drain valve.

Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, specifically to a rail vehicle air storage cylinder and a rail vehicle. Background Technology

[0002] Each rail vehicle is equipped with a main air cylinder, a brake air cylinder, and an auxiliary air cylinder. Each air cylinder has a drain valve at its base to remove condensate from the water vapor inside. These air cylinders are located under the car body. During commissioning and operation maintenance, the condensate and compressed air in the air cylinders need to be removed periodically. Specifically, during commissioning of the braking system, manual removal of compressed air from the air cylinders is required, while during operation and maintenance, manual removal of condensate is necessary.

[0003] Furthermore, in cold weather, when debugging or maintaining rail vehicles, the condensate in the drain valve below the air storage tank often freezes. When manually operating the air storage tank, it is inconvenient to drain the condensate in the tank, requiring additional heating or de-icing equipment for removal. This is cumbersome, increases maintenance or debugging time, reduces maintenance efficiency, and is labor-intensive.

[0004] Secondly, during the commissioning of rail vehicles, air needs to be vented from the air cylinders. This requires removing the equipment compartment floor plate to manually operate the air cylinders. Removing the equipment compartment floor plate requires four workers who must manually enter the rail vehicle's pit to operate the air cylinder drain valve. If the vehicle is not placed on a track with a maintenance trench but is placed in a parking lane, the vehicle skirts must be manually opened, and workers must crawl into the skirt support brackets to manually operate the system. After opening the equipment compartment floor plate or skirts, workers crawl into the pit or skirt and use a four-corner key or a triangular key to turn clockwise to open the drain valve, releasing the compressed air and condensate from the air cylinders. After the compressed air is released, workers must again crawl into the pit or skirt and use a four-corner key or a triangular key to turn counterclockwise to close the drain valve. This manual labor is quite strenuous. Summary of the Invention

[0048] This invention discloses an auxiliary working device for a rail vehicle air storage cylinder and air storage cylinder drain valve, which solves the problems of existing air cylinder drain valves freezing, requiring manual entry into the skirt support for de-icing and manual operation, resulting in high labor intensity and low work efficiency.

[0049] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0050] Please see Figure 1-11 , Figure 1 This is an axonometric structural diagram of the air storage cylinder of a rail vehicle provided in an embodiment of this application; Figure 2 This is a schematic diagram of the main structure of the air storage cylinder drain valve provided in an embodiment of this application; Figure 3 for Figure 2 A schematic diagram of the lateral structure; Figure 4 for Figure 3 Schematic diagram of the AA-direction structure; Figure 5 This is a schematic diagram of the structure of the heating device provided in the embodiments of this application; Figure 6 for Figure 5 Schematic diagram of the BB-oriented structure; Figure 7 This is a schematic diagram of the structure of the heating conductor provided in an embodiment of this application; Figure 8 This is a schematic diagram of the structure of the drain valve opening and closing assembly provided in the embodiments of this application; Figure 9 This is a schematic diagram of the opening and closing actuator provided in an embodiment of this application; Figure 10 for Figure 9 A partially enlarged structural diagram; Figure 11 This is a schematic diagram of the structure of a fan generator provided in an embodiment of this application.

[0051] In one specific embodiment, the rail vehicle air storage cylinder 200 provided in this application includes an air storage cylinder body 201 and a drain valve assembly 202, with the drain valve assembly 202 located at the bottom of the air storage cylinder. The drain valve assembly 202 includes a drain valve body 2021, a heating device 2022, and a displacement adjusting device 2023. The heating device 2022 is located inside the drain valve body 2021. One end of the displacement adjusting device 2023 is disposed on the drain valve body 2021, and the other end is located inside the drain valve body 2021 and connected to the heating device 2022, for adjusting the spatial position of the heating device 2022 within the drain valve body 2021. The bottom of the air storage cylinder body 201 has a drain outlet, and the drain valve assembly 202 is connected to the drain outlet of the air storage cylinder body 201 to collect condensate in the air storage cylinder body 201 and allow it to flow into the drain valve assembly 202, from where it is discharged to the outside.

[0052] The drain valve body 2021 can be cylindrical, rectangular, or other cylindrical structures, depending on the specific application requirements. The drain valve body 2021 is generally made of the inlet material, such as stainless steel or cast iron. The heating device 2022 is located inside the drain valve body 2021 and can directly heat the fluid, increasing the heating rate. It can be configured as a heating conductor 202213 or a heating resistance wire, etc., and is lightweight and easy to install and replace. The temperature of the heating device 2022 can be adjusted by controlling the current. In low-temperature environments, the heating device 2022 heats the water inside the drain valve body 2021 to prevent freezing and ensure the normal operation of the drain valve.

[0053] The displacement adjustment device 2023 can be configured as a linear slide rail mechanism. The displacement adjustment device 2023 is fixed to the drain valve body 2021 by means of threads or snaps. The other end is connected to the heating device 2022 by a mechanical structure, such as a screw or connecting rod. The position of the heating device 2022 can be adjusted manually or electrically to ensure the optimal heating effect.

[0054] The auxiliary working device 100 for the drain valve of the air storage cylinder provided in this application embodiment has the following technical advantages compared with the prior art:

[0055] The drain valve assembly 202 of this application is connected to the air storage cylinder body 201. The drain valve assembly 202 includes a drain valve body 2021 and a heating device 2022 located inside the drain valve body 2021. The heating device 2022 is located inside the drain valve body 2021, eliminating the need for manual carrying of additional de-icing or heating equipment, thus reducing manual operation costs and labor intensity. Secondly, a displacement adjustment device 2023 is located on the drain valve body 2021. One end of the displacement adjustment device 2023 is connected to the drain valve body 2021, and the other end is located inside the drain valve body 2021 and connected to the heating device 2022. By adjusting the spatial position of the heating device 2022 within the drain valve body 2021, different positions of the drain valve body 2021 can be heated to prevent water from freezing, shorten the de-icing time, improve de-icing efficiency, and further reduce labor costs and labor intensity.

[0056] Specifically, the heating device 2022 includes a heating body 20221, the outer circumferential wall of which has a pose adjustment surface 202211; the displacement adjustment device 2023 includes several telescopic adjustment rods 20231 and several positioning support surfaces, one end of any telescopic adjustment rod 20231 is located on the outer wall of the drain valve body 2021, and the other end extends into the drain valve body 2021, each telescopic adjustment rod 20231 is arranged circumferentially in the drain valve body 2021 and is located in the same radial section; the front end of each telescopic adjustment rod 20231 is provided with a positioning support surface adapted to the pose adjustment surface 202211, and the heating body 20221 is placed on each positioning support surface via the pose adjustment surface 202211; at least two telescopic adjustment rods 20231 move radially along the drain valve body 2021, driving the positioning support surface to push the pose adjustment surface 202211 to move radially.

[0057] One end of the telescopic adjusting rod 20231 is located on the outer wall of the drain valve body 2021, and the other end extends radially inward into the drain valve body 2021. The telescopic adjusting rod 20231 can be configured as a screw. The drain valve body 2021 has several mounting holes, each with an internal thread, such as a nut or other threaded structure. The screw is located in the mounting hole, and its external thread engages with the internal thread in the mounting hole. The extension length is adjusted by rotating the telescopic adjusting rod 20231. The extended end of the telescopic adjusting rod 20231, i.e., the front end, has a positioning support surface. The positioning support surface engages with the position adjustment surface 202211 of the heating element 20221. The heating element 20221 rests on the positioning support surface via the position adjustment surface 202211, meaning that all positioning support surfaces jointly support the heating element 20221. Each telescopic adjustment rod 20231 is evenly arranged around the circumference of the drain valve body 2021 and is located in the same radial section, so as to support the heating element 20221 and make its position adjustment surface 202211 uniformly stressed.

[0058] When the position of the heating element 20221 needs to be adjusted, the extension length of at least two telescopic adjustment rods 20231 is adjusted to drive the positioning support surface to push the position adjustment surface 202211 to move radially. Preferably, the extension length of two or four telescopic adjustment rods 20231 symmetrical about the center of the drain valve body 2021 is adjusted, thereby adjusting the horizontal position of the heating element 20221 in the radial section, so that it moves closer to the inner wall of the drain valve body 2021, expanding the heating range, preventing water from freezing, and shortening the de-icing time and improving the de-icing efficiency.

[0059] Specifically, the lower circumferential outer wall of the heating element 20221 gradually narrows from top to bottom, forming a position adjustment surface 202211. Based on the structure of the position adjustment surface 202211 with its gradually narrowing diameter from top to bottom, the positioning support surface is also set as an inclined surface from top to bottom. Thus, when the telescopic adjustment rod 20231 moves radially, the positioning support surface and the position adjustment surface 202211 slide together, driving the heating element 20221 to adjust its position vertically. This achieves vertical position adjustment of the heating element 20221 within the drain valve body 2021, further expanding the heating range and further shortening the de-icing time.

[0060] In one specific embodiment, the pose adjustment surface 202211 is an arc-shaped pose adjustment surface 202211, and the heating element 20221 is preferably a teardrop-shaped heating element 20221. This further reduces the weight of the heating element 20221 while ensuring the pose adjustment function, making it easier to operate and reducing system energy consumption. In another embodiment, the pose adjustment surface 202211 can also be a conical pose adjustment surface 202211. In other embodiments, other surface structures capable of achieving the pose adjustment purpose can also be used, all of which are within the protection scope of this application.

[0061] In one optional embodiment, the heating element 20221 is provided with a plurality of mounting cavities 202212, and each mounting cavity 202212 is provided with an insulating coating; at least one mounting cavity 202212 is provided with a heating conductor 202213, and at least one mounting cavity 202212 is provided with a wire 202214, one end of the wire 202214 is connected to the heating conductor 202213, and the other end is connected to an external power source.

[0062] The heating element 20221 has a hollow inner cavity and also has several mounting cavities 202212. The mounting cavities 202212 are used to mount heating conductors 202213 and wires 202214. Preferably, the mounting cavities 202212 for mounting heating conductors 202213 and wires 202214 are arranged in half. Each heating conductor 202213 is independently connected to a wire 202214. The other end of the wire 202214 is connected to an external power source to provide current to the heating conductor 202213. To prevent short circuits, the hollow inner cavity of the heating element is provided with an insulating coating. Simultaneously, each mounting cavity 202212 within the heating element 20221 also has an insulating coating. This prevents short circuits between the wires 202214 and the housing after damage, protecting the insulation performance of the wires 202214. Furthermore, it prevents direct contact between the heating conductors 202213 and the heating element 20221, protecting the insulation performance of the copper conductors. The heating conductor 202213 is made of copper and is preferably rectangular. The number of heating conductors 202213 can be set according to the heating power.

[0063] Specifically, the heating conductor 202213 includes a strip conductor 2022131 and an arc conductor 2022132; the strip conductor 2022131 is provided with several sets of mounting holes and wire mounting holes 2022133, and each set of mounting holes is symmetrically arranged at both ends of the length direction of the strip conductor 2022131; the arc conductor 2022132 is provided with mounting pins at both ends of the length direction, and the mounting pins are fixed to the strip conductor 2022131 via mounting bases and mounting holes.

[0064] Several sets of mounting holes for the strip conductor 2022131 are symmetrically arranged at both ends of the strip conductor 2022131 along its length. Simultaneously, each end of the strip conductor 2022131 along its length is provided with a wire mounting hole 2022133 for connecting wires. Each set of mounting holes includes strip-shaped mounting holes and circular mounting holes. The two ends of the arc-shaped conductor 2022132 are provided with circular mounting holes, which are fixed to the circular mounting holes of the strip conductor 2022131 by threaded fasteners. Mounting base 20221 The 34 is also provided with a circular mounting hole. The mounting base 2022134 and the arc-shaped conductor 2022132 are located on the front and back sides of the strip conductor 2022131, respectively. The mounting base 2022134 and the arc-shaped conductor 2022132 are fixed on the strip conductor 2022131 by threaded fasteners. The mounting base 2022134 is also provided with a strip-shaped positioning block. The strip-shaped positioning block is engaged with the strip-shaped mounting hole to limit the mounting base 2022134 and further ensure the connection firmness of the arc-shaped conductor 2022132.

[0065] At least one set of arc conductors 2022132 is set up. The arc conductors 2022132 are set up according to the required heating power. Different sets of arc conductors 2022132 can be installed on the strip conductors 2022131 at the same time. When multiple sets of arc conductors 2022132 are set up, the curvature radius of each set of arc conductors 2022132 can be set differently, so that different sets of arc conductors 2022132 can be installed on the mounting holes, which is convenient for installation and configuration.

[0066] Furthermore, the heating device 2022 is a microwave heating device 2022, which includes a microwave generator and a microwave controller 202216. The microwave generator is connected to the microwave controller 202216. The microwave generator is housed inside the heating body 20221, and the microwave controller 202216 is located on the drain valve body 2021, controlling the microwave generator to emit microwaves. The heating body 20221 has several microwave emission holes 202215 around its circumference for the microwaves emitted by the microwave generator to pass through. Preferably, there are four microwave emission holes 202215, which are evenly distributed around the circumference of the heating body 20221, uniformly emitting microwaves around the drain valve body 2021 to improve the uniformity of heating. With this configuration, the heating device 2022 heats the drain valve body 2021 through both microwave heating and heating conductor 202213, further expanding the heating range and further shortening the de-icing time.

[0067] Preferably, the drain valve body 2021 is further provided with a temperature detection device and a control device. The temperature detection device detects the temperature inside the drain valve body 2021. When the temperature is less than or equal to the preset temperature, the control device controls the heating device 2022 to start, and heats the drain valve body 2021 through the microwave generator and the heating element 20221 respectively. The preset temperature can be set to 5°C to maintain a certain temperature inside the drain valve body 2021 and prevent the condensate in the cavity from freezing.

[0068] Specifically, the drain valve body 2021 is also equipped with an FRID chip 202217, which is used in conjunction with the auxiliary working device 100 for the drain valve of the air reservoir to record the number of drainages, status and usage time.

[0069] More preferably, an internal pressure-sensitive coating is provided inside the drain valve body 2021. This coating, applied inside the drain valve body 2021, changes color according to pressure changes. Maintenance personnel can directly observe the color of the internal pressure-sensitive coating through the observation window 202218 to determine the internal pressure changes of the valve body. Simultaneously, a circular observation window 202218, made of a high-strength transparent material, is provided on the drain valve body 2021. This window isolates the internal pressure of the valve body, allowing external light to enter. Maintenance personnel can then observe the internal structure of the valve body through the circular observation window 202218. The internal pressure-sensitive coating not only reflects pressure changes through color changes but also converts the internal pressure of the steel body into an electrical signal, which can be used as a backup pressure sensor. For example, if it is necessary to collect the internal pressure of the air storage cylinder, a pressure control processing device needs to be installed for the acquisition and control of the pressure signal within the air storage cylinder.

[0070] In this embodiment, the drain valve assembly 202 further includes a drain valve core and a drain valve opening / closing assembly 2024. The drain valve core is located within the drain valve body 2021, and its specific structure can be configured according to existing technology, which will not be elaborated here. The drain valve opening / closing assembly 2024 is connected to the bottom drain outlet of the drain valve body 2021. It includes a mounting sleeve 20241, an opening / closing actuator 20242, and a drain valve stem. Specifically, the mounting sleeve 20241 is connected to the bottom outlet of the drain valve body 2021. The opening / closing actuator 20242 is rotatably connected to the outer wall of the mounting sleeve 20241. The drain valve stem is located within the mounting sleeve 20241, with one end connected to the opening / closing actuator 20242 and the other end connected to the drain valve core. The opening / closing actuator 20242 rotates to drive the drain valve stem, which in turn drives the drain valve core to open or close.

[0071] The opening and closing actuator 20242 can be configured as a lock structure, such as a triangular lock or a square lock. Its lock core is connected to the drain valve stem. The rotation of the lock core can drive the drain valve stem to rotate, thereby driving the drain valve stem to open or close the drain valve core and realize the discharge of condensate.

[0072] Specifically, the opening and closing actuator 20242 includes an annular protective boss 202421 and a cross-shaped lock body 202422; the annular protective boss 202421 is located on the outer cylinder wall of the mounting sleeve 20241 and has an inner cavity; the cross-shaped lock body 202422 is located in the inner cavity of the annular protective boss 202421 and on the outer cylinder wall of the mounting sleeve 20241, the cross-shaped lock body 202422 is connected to the drain valve stem and can rotate relative to the mounting sleeve 20241; the center of the cross-shaped lock body 202422 is provided with an arc-shaped groove 202423, and a strip-shaped lock core 202424 that divides the arc-shaped groove 202423 into two is provided in the arc-shaped groove 202423. Correspondingly, the opening and closing assembly of the auxiliary operating device 100 for the air reservoir drain valve has a cross-shaped groove corresponding to the opening and closing actuator 20242, and an arc-shaped protrusion is provided at the center of the cross-shaped groove. The arc-shaped protrusion has a strip-shaped groove that divides the arc-shaped protrusion into two. In other embodiments, the cross-shaped lock body 202422 can also be set as a rectangle or a triangle, which can be set according to the actual application; correspondingly, the auxiliary operating device 100 for the air reservoir drain valve should also be set accordingly.

[0073] On the one hand, in order to exhaust the air from the main body 201 of the air storage cylinder, the aforementioned rail vehicle air storage cylinder 200 includes at least two sets of exhaust valve assemblies 203; preferably, one set of exhaust valve assemblies 203 is provided on each of the longitudinal sides of the main body 201 of the air storage cylinder; each set of exhaust valve assemblies 203 includes a first control valve 2031, a second control valve 2032, two fan generators 2033 and a cross pipe 2034, the first control valve 2031 and the second control valve 2032 and the two fan generators 2033 are respectively arranged opposite to each other on the cross pipe 2034; the first control valve 2031 is connected to the exhaust port of the main body 201 of the air storage cylinder, and the second control valve 2032 is connected to the atmosphere; the fan generators 2033 are connected to the drain valve assembly 202 to provide electrical energy.

[0074] The first control valve 2031 and the second control valve 2032 are located at both ends of the cross pipe 2034 corresponding to the transverse direction of the air storage cylinder body 201. The two fan generators 2033 are located at both ends of the cross pipe 2034 corresponding to the longitudinal direction of the air storage cylinder body 201. The first control valve 2031 is used to control the connection between the air storage cylinder body 201 and the cross pipe 2034. The second control valve 2032 is used to control the connection between the cross pipe 2034 and the atmosphere. The fan generators 2033 are connected to the drain valve assembly 202 through wires to supply power to the heating device 2022.

[0075] The structures of the first control valve 2031 and the second control valve 2032 may be the same or different. In this embodiment, the first control valve 2031 and the second control valve 2032 are the same. Specifically, the first control valve 2031 and the second control valve 2032 respectively include: a control valve body and a control valve core, with the control valve core located inside the control valve body; a control valve opening and closing assembly located on the control valve body, which includes a control valve mounting sleeve 20241, a control valve opening and closing actuator 20242, and a control valve stem. The control valve mounting sleeve 20241 is fitted onto the outside of the control valve body, and the control valve opening and closing actuator 20242 is rotatably connected to the outer wall of the control valve mounting sleeve 20241. The control valve stem is located inside the control valve mounting sleeve 20241, with one end connected to the control valve opening and closing actuator 20242 and the other end connected to the control valve core. When the control valve opening and closing actuator 20242 rotates, it drives the control valve stem to open or close the control valve core.

[0076] It is understandable that, except for the different positions of the control valve mounting sleeve 20241 and the control valve body, and the mounting sleeve 20241 and the drain valve body 2021, the structures of the first control valve 2031 and the second control valve 2032 can be set with reference to the drain valve opening and closing assembly 2024.

[0077] The control valve opening and closing actuator 20242 can be configured as a lock structure, such as a triangular lock or a square lock. Its lock core is connected to the control valve stem. The rotation of the lock core can drive the control valve stem to rotate, thereby driving the control valve stem to open or close the control valve core and realize the discharge of condensate.

[0078] Similarly, the control valve opening and closing actuator 20242 includes a control valve annular protective boss 202421, which is located on the outer wall of the control valve mounting sleeve 20241 and has an inner cavity; a control valve cross-shaped lock body 202422 is located in the inner cavity of the control valve annular protective boss 202421, and a control valve arc-shaped groove 202423 is provided at the center of the control valve cross-shaped lock body 202422. A control valve strip-shaped lock core 202424, which divides the control valve arc-shaped groove 202423 into two, is provided within the control valve arc-shaped groove 202423. The opening and closing assembly of the auxiliary operating device 100 for the air reservoir drain valve is correspondingly provided with a key complementary to the control valve opening and closing actuator 20242. Specific details can be found by referring to the key corresponding to the opening and closing actuator 20242 described above, and will not be repeated here.

[0079] In this specific embodiment, the fan generator 2033 provided in this application includes two fan generator bodies 20331, a circular mounting bracket 20332 and a cross-shaped mounting bracket 20333, with the cross-shaped mounting bracket 20333 fixed inside the circular mounting bracket 20332; the two fan generator bodies 20331 are respectively located at the center of the front and back sides of the cross-shaped mounting bracket 20333;

[0080] The four vertices of the cross-shaped mounting bracket 20333 are fixed to the inner wall of the circular mounting bracket 20332, preferably as an integral part; a fan generator 2033 is provided at the center of the front and back sides of the cross-shaped mounting bracket 20333, and the fan generator 2033 is fixedly connected to the cross-shaped mounting bracket 20333. The specific structure of the fan generator body 20331 can be set according to the existing technology.

[0081] Meanwhile, in order to install the fan generator 2033 and the cross pipe 2034, a mounting positioning pin 20334 is provided at the end of one set of opposite sides of the cross-shaped mounting bracket 20333, and a positioning hole 20335 for fixing to the cross pipe 2034 is provided at the end of the other set of opposite sides. Correspondingly, the cross pipe 2034 is provided with a mounting positioning groove and a positioning hole 20335. The mounting positioning groove and the mounting positioning pin 20334 correspond to each other, and the positioning hole 20335 of the cross-shaped mounting bracket 20333 corresponds to the positioning hole 20335 of the cross pipe 2034. The installation of the two can be achieved by setting a threaded fastener in the positioning hole 20335.

[0082] The specific operating process of the exhaust valve assembly 203 is as follows: When the rail vehicle is in operation, the aforementioned rail vehicle air storage cylinder 200 is installed under the vehicle body. As the rail vehicle runs, this device also moves at high speed along with it. The first control valve 2031 is closed, and the second control valve 2032 is open. Because the rail vehicle is running at high speed, high-speed airflow passes under the vehicle body and flows through the fan generator 2033 – cross pipe 2034 – second control valve. The fan in the fan generator 2033 rotates at high speed driven by the high-speed airflow, driving the generator to generate electricity, converting the mechanical energy of the high-speed airflow into electrical energy. Since two fan generators 2033 are installed on each side of the air storage cylinder in a front-rear direction, regardless of the vehicle's direction of travel, these fan generators 2033 can convert the mechanical energy of the vehicle's movement into electrical energy, supplying power to the entire device.

[0083] When the rail vehicle is stationary and power is needed to power the device, the first control valve 2031 is opened and the second control valve 2032 is closed. The air in the main body 201 of the air storage cylinder flows through the first control valve 2031, the cross pipe 2034 and the fan generator 2033. The fan in the fan generator 2033 rotates at high speed under the drive of the high-speed airflow. The fan drives the generator to generate electricity, converting the mechanical energy of the high-speed airflow into electrical energy.

[0084] The specific operation process of the drain valve assembly 202 is as follows: When the rail vehicle is stored outdoors in a cold environment for a long time while stationary, the condensate in the drain valve body 2021 will freeze at low temperatures; the auxiliary working device 100 closes the second control valve 2032 and opens the first control valve 2031 through the drain valve of the air storage cylinder, and the compressed gas in the air storage cylinder body 201 will form a channel through the first control valve 2031, the cross pipe 2034 and the fan generator 2033, and the compressed gas will be discharged into the atmosphere through the above-mentioned pipe channel; when the high-pressure gas passes through the fan generator 2033 at high speed, the high-speed running gas will drive the fan to rotate at high speed, and the fan will drive the generator to run, converting the kinetic energy of the high-speed running gas into electrical energy; the converted electrical energy supplies power to the microwave controller 202216, the microwave generator, the heating conductor 202213 and the control device; due to the need for rapid de-icing operation, the microwave controller 202216 is powered on at this time, and the microwave controller 202216 controls the microwave The generator emits microwaves, which are emitted through the four microwave emission holes 202215 of the teardrop-shaped heating element 202214. The emitted microwaves are reflected by the cavity wall inside the drain valve body 2021 and reflected to the icing area, where the condensate is de-iced. The operator can observe the pressure change inside the drain valve body 2021 by observing the color change of the pressure-sensitive coating in the observation window 202218. When the pressure change inside the drain valve body 2021 is zero, the drain valve assembly 202 is opened by the auxiliary working device 100 connected to the drain valve opening and closing actuator 20242. Since the condensate has been de-iced before opening, the condensate will be discharged to the ground through the drain valve assembly 202 under the action of gravity. The auxiliary working device 100 of the drain valve connects to the drain valve opening and closing actuator 20242 to close the opened drain valve assembly 202. At this time, the drainage operation of the drain valve of the rail vehicle's air storage cylinder 200 is completed.

[0085] Based on the rail vehicle air storage cylinder provided in the above embodiments, this application also provides a rail vehicle including the above-mentioned rail vehicle air storage cylinder. The rail vehicle further includes a car body and an auxiliary working device for the air storage cylinder drain valve. The air storage cylinder is located below the car body, and the auxiliary working device for the air storage cylinder drain valve is used to open and close the drain valve assembly of the rail vehicle air storage cylinder.

[0086] Please see Figure 12-13 In one specific embodiment, the auxiliary operating device for measuring the drain valve of the air storage tank provided in this application includes:

[0087] A boom 1 that can extend, retract, and be fixed along the axial direction;

[0088] Opening and closing assembly 2 is used to open and close the drain valve assembly. Opening and closing assembly 2 is located at the shaft end of arm 1.

[0089] The de-icing assembly 4 is fixed to the shaft end of the boom 1 and is used to de-ic the drain valve assembly after it has frozen.

[0090] The boom 1 can extend and retract along its own axis and be fixed. The extension length of the boom 1 can be adjusted according to the lateral position of the drain valve assembly on the rail vehicle so that the opening and closing component 2 can be extended into the track to realize the opening and closing operation of the drain valve assembly. This eliminates the need for operators to enter the pit or skirt of the rail vehicle, preventing dust and sand from flying into their eyes during operation and reducing the probability of work-related accidents; at the same time, it reduces labor costs and labor intensity.

[0091] The opening and closing assembly 2 can open and lock the drain valve assembly. The locking structure of the drain valve assembly can be configured as a triangular lock or a square lock, and can be adjusted and switched according to the shape of the locking structure of the drain valve assembly. After connecting with the locking structure of the drain valve assembly, the arm 1 rotates along its own axis, converting the rotational force generated by the arm 1 into the force for opening and closing the locking structure of the drain valve assembly, realizing the conversion and transmission of the operating rotational force. Optionally, the opening and closing assembly 2 includes a triangular opening and closing mechanism 21 and a square opening and closing mechanism 22; the triangular opening and closing mechanism 21 is used to open or close the triangular lock of the drain valve assembly; the square opening and closing mechanism 22 is used to open or close the square lock of the drain valve assembly; in other embodiments, the opening and closing assembly 2 can be configured according to the specific form of the locking structure of the air storage cylinder drain valve, which will not be described in detail here. The opening and closing assembly 2 is located at the shaft end of the arm 1 and can move synchronously along the axial direction when the arm 1 extends and retracts, so as to adapt to the setting position of the air storage cylinder drain valve of different rail vehicles and improve the applicability of the device.

[0092] The de-icing assembly 4 is fixed to the axial front end of the boom 1 and performs de-icing operations on the drain valve assembly after it has frozen. The de-icing assembly 4 performs de-icing operations on the drain valve of the air storage cylinder when the outside temperature is low. The de-icing assembly 4 can be specifically configured as a heating element, such as a heating resistance wire, etc. The heating element blows out hot air to heat up the drain valve of the air storage cylinder, so that the ice inside the drain valve of the air storage cylinder melts and the de-icing operation is achieved. The temperature and air volume of the de-icing assembly 4 can be controlled by preset. When the outside temperature is low, the de-icing efficiency can be improved by adjusting the temperature.

[0093] The de-icing assembly 4 is fixed to the arm 1 using fastening bolts. The fastening bolts are custom-made cylindrical metal bolts with a 4mm stud at the front end and a regular hexagonal structure at the rear end for rotating the fastening bolts. The front stud is coaxial with the mounting hole of the de-icing device through the mounting hole of the second arm 102. By rotating, the de-icing device is fastened, preventing the de-icing assembly 4 from moving up and down on the second arm 102.

[0094] This application mounts the opening and closing assembly 2 on the boom 1. The opening and closing assembly 2 is used to open and lock the drain valve assembly. The boom 1 can extend and retract along its own axis and is fixed. The opening and closing assembly 2 is sent into the track through the axial extension and retraction of the boom 1, and the opening and closing assembly is connected to the locking structure of the drain valve assembly. The opening and closing of the drain valve assembly is achieved by rotating the boom 1 around its own axis to drive the opening and closing assembly 2 to rotate. This eliminates the need for operators to crawl into the track or skirt support to operate, reducing manual operation costs and labor intensity, and improving the operating efficiency of the drain valve assembly. At the same time, the de-icing assembly 4 performs de-icing operations on the drain valve assembly, shortening the de-icing time and improving the de-icing efficiency, while further reducing labor costs and labor intensity.

[0095] In another embodiment, the above-mentioned auxiliary working device further includes:

[0096] The mounting bracket has several mounting rods, and the opening / closing assembly and the de-icing assembly are located on the mounting rods respectively.

[0097] The rotary drive assembly, with one end connected to the boom and the other end connected to the mounting bracket, is used to drive the mounting bracket to rotate, thereby switching each mounting rod to rotate closer to the front end of the boom.

[0098] One end of the rotary drive assembly is perpendicular to the axis of the boom, preferably located below the boom. The other end of the rotary drive assembly is connected to the mounting bracket, which has several mounting rods. Each mounting rod can be equipped with different functional components as needed. In this embodiment, the opening / closing assembly and the de-icing assembly are located on two mounting rods respectively. The rotary drive assembly drives the mounting bracket to rotate, moving the functional components required for the next maintenance operation closer to the front end of the boom. For example, if de-icing is required before opening or closing the drain valve of the air reservoir, the rotary drive assembly is controlled to rotate, moving the mounting rod containing the de-icing assembly closer to the front end of the boom. Preferably, the mounting rod is parallel to the boom. After the de-icing operation is completed, when opening or closing the drain valve of the air reservoir, the rotary drive assembly is controlled to drive the mounting bracket to rotate, moving the mounting rod containing the opening / closing assembly closer to the front end of the boom. Again, the mounting rod is parallel to the boom to optimize the space utilization at the front end of the boom, allowing for the switching of functional components according to different needs.

[0099] The rotary drive assembly 3 is a rotary motor. The fixed base of the rotary motor is fixedly connected to the bottom surface of the arm 1, such as by using threaded fasteners. The output end of the rotary motor is fixedly connected to the mounting bracket, which drives the mounting bracket to rotate around its own axis. The rotary motor is a DC motor and rotates under the control of the display screen 81. The rotary motor has a built-in speed reduction structure to drive the mounting bracket to rotate.

[0100] Optionally, the boom 1 includes a first boom 101 and a second boom 102, which are fitted together. The second boom 102 is fitted into the internal cavity of the first boom 101 and can reciprocate along the length of the first boom 101. The inner diameter of the first boom 101 is larger than the outer diameter of the second boom 102. The second boom 102 is fitted into the internal cavity of the first boom 101 with a clearance fit. The second boom 102 reciprocates along the axial direction of the first boom 101, driving the rotary drive assembly 3 and the opening and closing assembly 2 mounted on the second boom 102 to move axially and approach the locking mechanism of the drain valve of the air reservoir, thereby realizing the opening and closing of the drain valve assembly. The first boom 101 and the second boom 102 realize the axial movement of the boom 1. The structure is simple and easy to set up.

[0101] Furthermore, one of the first boom 101 and the second boom 102 is provided with a limiting protrusion, and the other with a limiting recess. The limiting protrusion and the limiting recess cooperate to limit the circumferential rotation of the boom 1. There are two limiting protrusions, and correspondingly, there are also two limiting recesses. The two limiting protrusions are symmetrically arranged along the axis to limit the circumferential rotation of the boom 1 and guide the axial movement between them. The end of the second boom 102 adopts an anti-slip design to increase friction and prevent slippage during operation. During operation, the rotational force of the handle is transmitted to the locking mechanism of the air reservoir drain valve through the boom 1 to open and close the drain valve assembly. A rotating lever is added inside the boom 1. A small force is output on the handle, and 2-3 times the rotational force is output on the opening and closing assembly 2. The rotational force can be adjusted on the boom 1.

[0102] Furthermore, the boom 1 also includes a locking member 103 located at the front end of the first boom 101, used to lock the first boom 101 and the second boom 102, limiting the axial movement between the first boom 101 and the second boom 102. The locking member 103 is a circular ring structure, installed on the first boom 101, with the second boom 102 fitted inside it. After the extension position of the second boom 102 is adjusted, the locking member 103 is screwed on to lock the second boom 102, preventing axial movement between the second boom 102 and the first boom 101. The locking member 103 is preferably a locking nut, with the front end of the first boom 101 having an open threaded portion, and several openings arranged axially. The locking nut and the openings are used to lock the first boom 101 and the second boom 102. In other embodiments, the specific structure of the locking member 103 can be set as needed, all of which are within the protection scope of this application.

The monitoring component 5 is preferably a visual monitoring sensor, controlled by a DC power supply, connected to the display screen 81 via a network, transmitting image signals during operation to the display screen 81, and displaying the image signals in real time on the display screen 81. The image signals on the display screen 81 can be transferred and data sent to a host computer for storage. The monitoring component 5 collects the surrounding environment and the on / off status of the drain valve assembly during operation, and stores the image data of the drain valve assembly's status. Connected to the display screen 81 via a cable, the surrounding environmental information and the drain valve's status information during operation are transmitted to the display screen 81, converting the physical quantity of moisture content in the compressed air into an electrical signal and displaying it on the display screen 81.

[0104] In another optional embodiment, the above-mentioned auxiliary working device further includes a compressed air moisture detection component 6, which is located at the axial end of the second arm 102 away from the first arm 101, and is used to detect the moisture content in the compressed air of the drain valve assembly.

[0105] The compressed air moisture detection component 6 is specifically a compressed air moisture detection sensor, which is a cylindrical hollow structure shell. The compressed air moisture detection sensor is installed inside the hollow structure shell. When compressed air passes through the hollow structure shell, it comes into contact with the sensor inside. The compressed air moisture detection sensor is connected to the display screen 81 through a cable. The moisture test data in the compressed air is converted and calculated by the display screen 81 and displayed on the display screen 81.

[0106] Specifically, the aforementioned auxiliary operating device also includes an RFID reading component 7, located at the end of the second arm 102 opposite to the first arm 101, used to read and write data from the RFID chip of the air reservoir drain valve, thereby realizing the transfer of operating data.

The display mounting box 83 is also a rectangular metal structure with a hollow interior. Second mounting holes, threaded holes, are provided at the top perimeter of the display mounting box 83. These are used to mechanically connect the display mounting panel 82 and the display mounting box 83 via bolts. These bolts are ordinary hexagonal bolts that engage with four cylindrical bolts at the bottom of the display mounting box 83 to achieve the mechanical connection. The power switch 11 has a rectangular mounting hole and two circular mounting holes for the antenna 12 and power indicator light 10. A fastening assembly at the bottom of the display mounting box 83 connects it to the first arm 101, thus achieving a mechanical connection between the display mounting box 83 and the first arm 101.

[0112] The display screen 81 is used for real-time monitoring of operation images and displaying real-time moisture content data in compressed air, as well as for operation control of the de-icing device. The display screen 81 displays operation data from the RFID chip in the data transmission device; it also enables the storage and display of operation data; and facilitates communication and data calculation with the compressed air moisture detection sensor and the visual monitoring sensor.

[0149] 7. After the compressed air moisture test is completed, connect the opening and closing mechanism to the keyhole of the drain valve assembly. Rotate arm 1 counterclockwise to close the drain valve assembly door, aligning it with the closed mark on the air cylinder.

[0150] 8. Bring the RFID reader / writer in the data transmission device into close contact with the RFID chip below the air cylinder to write the operation information into the RFID chip. The operation information includes: time, operator, and drain valve status.

[0151] 8. Place the visual monitoring sensor near the air cylinder exhaust valve to take pictures and record the status of the air cylinder drain valve, and save the operation data, status data and moisture test data. The data transmission device sends the above information to the host computer for storage through the workshop wireless network.

[0152] 9. After the test is completed, turn off the drain valve of the air storage cylinder using the auxiliary working device and clean the site.

[0153] Example 4

[0154] 1. Check that the auxiliary working device for the air reservoir drain valve is in good condition, has sufficient power, and that the vehicle to be operated is placed inside the factory.

[0155] 2. Turn on the power supply of the auxiliary working device to open the drain valve of the air storage cylinder. The corresponding power indicator light 10 will light up, and the display screen 81 will light up. The display screen 81 will display the video image collected by the visual sensor and monitor the operation process.

[0156] 3. Extend boom 1, and at the same time rotate the opening and closing mechanism at the head of boom 1 to correspond to the key-shaped opening and closing mechanism of the drain valve assembly.

[0157] 4. Connect the opening and closing mechanism to the key-shaped opening of the drain valve assembly. Rotate the lever 1 clockwise to open the drain valve assembly door and align it with the open mark on the air cylinder.

[0158] 5. When the drain valve assembly door is opened, a corresponding exhaust sound should be heard. If no exhaust sound is heard, and the air cylinder pressure gauge indicates pressure in winter when the outside temperature is low, it means that the condensate inside the drain valve assembly has frozen, causing the drain valve to become blocked, and de-icing is required.

[0159] 6. Connect the opening and closing mechanism to the key-shaped opening of the drain valve assembly. Rotate the lever 1 counterclockwise to close the drain valve assembly, aligning it with the closed mark on the air cylinder.

[0160] 7. Place the de-icing device on arm 1 below the drain valve assembly. On the display screen 81, click the de-icing operation. The head fan of the de-icing device will rotate, indicating heating has started, and high-temperature gas will be blown out from the head of the de-icing device. This high-temperature gas blows onto the metal components surrounding the drain valve assembly, heating them up. Once the internal temperature rises, the condensate will automatically defrost. The display screen 81 offers two modes: normal de-icing and fast de-icing. The corresponding de-icing temperature can be adjusted via the touchscreen, allowing for adjustable de-icing temperature.

[0161] 8. After the de-icing device has been working for a period of time, turn it off. Connect the opening / closing mechanism to the keyhole of the drain valve assembly and rotate lever 1 clockwise. The drain valve assembly will open, aligning with the open mark on the air cylinder. A corresponding exhaust sound should be heard when the drain valve assembly opens. No further de-icing operation is needed. Once the exhaust sound is no longer heard, continue the de-icing operation as described in step 7 until an exhaust sound is heard when the drain valve assembly opens.

[0162] 9. After completing steps 1-8, you can proceed with the operations of Example 1, Example 2, and Example 3.

[0163] The aforementioned auxiliary operating device utilizes an opening / closing assembly 2 and a telescopic boom 1 to open the drain valve of the air reservoir of the rail vehicle without requiring manual entry into the track or under the vehicle. An anti-icing assembly 4 is added to the front end of the boom 1 to de-ic the drain valve when the outside temperature is low. A compressed air moisture detection assembly 6 is added to the boom head to detect the moisture content in the compressed air after the drain valve is opened. An RFID reader / writer is added to the boom head, and an RFID chip is added to the air reservoir to enable the reading and writing of operational data from the rail vehicle's air reservoir, as well as the writing of the previous compressed air moisture test data. An additional camera is added to enable remote monitoring of operations and the status of the rail vehicle's air storage cylinder, and to store the status of the drain valve in images. A monitoring display screen 81 is added to the lower part of the boom 1 to monitor, read, and display operations, read and write RFID chip data, and detect the moisture content in the compressed air, displaying it on the screen 81. The handle end is designed with a non-slip grip for easy handling and force application, enabling the opening and closing of the drain valve assembly. A remote data transmission function is added to transmit operation data and compressed air moisture data to the host computer via a wireless transmission device.

[0164] This system simplifies the operation of draining the air cylinders in rail vehicles, reducing manual operation costs and labor intensity. During operation, it detects moisture levels in the compressed air of the braking system, preventing excessive moisture and providing early warning. It also reduces the difficulty of manual operation, preventing dust and sand from entering the eyes and causing workplace injuries. Furthermore, it provides visual monitoring of the operation of the draining air cylinders and enables electronic recording and retrieval of operation records. The system improves the efficiency of draining air cylinder operation, reducing the time required for two people to operate for two hours to one person per hour. In winter, the addition of a de-icing device allows for rapid de-icing, eliminating the need for manual screwdriver operation and further improving the efficiency and safety of draining air cylinder operation.
