Description

Technical Field

[0001] This invention relates to the field of locomotive cleaning technology, and in particular to a locomotive air conditioning cleaning device and cleaning method. Background Technology

[0002] Locomotive air conditioning is an important piece of equipment in railway passenger locomotives. It requires regular cleaning of the outer shell, internal radiator, and other internal areas to ensure its stable operation.

[0003] In related technologies, locomotive air conditioning cleaning is generally carried out manually. Cleaning personnel often need to first push the air conditioner to the cleaning work area, and then use a spray gun to spray cleaning agent on the top of the air conditioner casing, the internal radiator and other internal areas, and then use a high-pressure spray gun to rinse it. However, during manual cleaning, especially when cleaning the radiator, it is often necessary to clean from the bottom of the air conditioner, which requires going up and down the trench or frequently squatting down to clean it. This results in problems such as poor cleaning effect, high labor intensity and low cleaning efficiency in locomotive air conditioning cleaning. Summary of the Invention

[0010] In some embodiments, the rotary drive is disposed on the support platform, and two first transmission wheels are spaced apart along the second direction on the support platform. A flexible member is disposed between the two first transmission wheels. A second transmission wheel is disposed at the output end of the rotary drive, and the second transmission wheel is motive-connected to the flexible member.

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] 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 or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0021] In the description of this invention, unless otherwise expressly 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 being 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 being 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.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 5 As shown, the present invention provides a locomotive air conditioning cleaning device, which includes a truss 1, a transport mechanism 2, and a cleaning mechanism 3. The transport mechanism 2 includes a transport drive assembly 21, a lifting hook 22, and a support rail 23; the support rail 23 extends along a first direction to support the locomotive air conditioner (the first direction is...). Figure 1 (in the X direction); two sets of transport drive components 21 are provided, and the two transport drive components 21 are respectively set on the truss 1 on both sides of the support rail 23. Each set of transport drive components 21 is provided with a lifting hook 22 at its output end, so as to drive the lifting hook 22 to move along the first direction and to rise and fall along the height direction of the truss 1 (the height direction is... Figure 1(Z direction in the middle); the cleaning mechanism 3 includes an upper cleaning component 31 and a lower cleaning component 32. The upper cleaning component 31 includes an upper cleaning drive 311 and an upper nozzle 312. The upper cleaning drive 311 is located above the support rail 23, and the upper nozzle 312 is located at the output end of the upper cleaning drive 311. The lower cleaning component 32 includes a lower cleaning drive 321 and a lower nozzle 322. The lower cleaning drive 321 is located below the support rail 23, and the lower nozzle 322 is located at the output end of the lower cleaning drive 321. The lower cleaning drive 321 can drive the lower nozzle 322 to rise and fall relative to the support rail 23.

[0024] The locomotive air conditioning cleaning device provided by this invention can clean the top, side walls, and internal space of the locomotive air conditioner through the upper cleaning component 31; while the lower cleaning component 32 can enter the interior from the bottom of the locomotive air conditioner to clean the internal radiator. Automatic cleaning can improve the cleaning effect compared with manual cleaning. Throughout the process, the handling drive component 21 can drive the lifting hook 22 to realize the handling, reducing labor intensity and improving cleaning efficiency. In particular, when the lower cleaning component 32 enters the interior of the locomotive air conditioner, the locomotive air conditioner can also be lifted and lowered by the lifting hook 22, without the need to set up a trench and without personnel operation, thus improving efficiency.

[0025] It should also be noted that in the current embodiment, the transport drive assembly 21 is located on both sides, which reduces the situation of setting too many drives under the locomotive air conditioner, reduces the situation of being dripped with cleaning liquid for a long time, and can extend the overall service life of the device.

[0026] like Figure 1 As shown, in some embodiments, the truss 1 further includes a top beam 12 extending along a second direction, wherein the second direction is... Figure 1 The Y-direction is perpendicular to both the first direction and the height direction; the upper cleaning assembly 31 is mounted on the top beam 12. Specifically, as shown... Figure 2 As shown, the upper cleaning assembly 31 also includes a connecting pipe 313, one end of which is rotatably connected to a multi-axis robotic arm. The multi-axis robotic arm is a commonly used type of robotic arm in the prior art and will not be described in detail here. The other end of the connecting pipe 313 is provided with a rotating seat 314, which can rotate along the axial direction of the connecting pipe 313. The upper nozzle 312 is rotatably connected to the rotating seat 314 via a rotating shaft, thereby making the spray direction of the upper nozzle 312 adjustable relative to the axial direction of the connecting pipe 313, expanding the cleaning range, and facilitating the cleaning of various internal corners and the sides of the locomotive air conditioner. In this embodiment, the upper nozzle 312 is a thin tube, which can cooperate with the connecting pipe 313 to facilitate entry into the locomotive air conditioner for cleaning, reducing the generation of blind spots.

[0027] like Figure 1As shown, in some embodiments, the support track 23 includes two support frames spaced apart. The upper cleaning assembly 31 and the lower cleaning assembly 32 are both disposed between the two support frames. Each support frame is rotatably equipped with several support rollers, allowing the locomotive air conditioner to be supported on the support rollers. The rotation of the support rollers makes it easier to move the locomotive air conditioner. like Figure 3 and Figure 4 As shown, in some embodiments, the lower cleaning assembly 32 includes a support platform 323, which is disposed between two support frames. The height of the support platform 323 is lower than the support height of the support rail 23. A blocking drive member 325 is disposed on the support platform 323, and a blocker 324 is disposed at the output end of the blocking drive member 325. The blocker 324 is disposed upstream of the lower nozzle 322. The upstream and downstream are determined based on the movement direction of the locomotive air conditioner on the support rail 23. The blocking drive member 325 can drive the blocker 324 to rise and fall relative to the support platform 323, thereby raising the blocker 324 above the support height of the support rail 23, blocking the locomotive air conditioner moving on the support rail 23, determining the location of the locomotive air conditioner, and facilitating initial positioning for subsequent operations. When it is necessary for the locomotive air conditioner to continue moving, the blocking drive member 325 only needs to drive the blocker 324 to descend and avoid it. In the current embodiment, the blocking drive member 325 may be, but is not limited to, a cylinder or a hydraulic cylinder.

[0028] In some embodiments, two support seats 3213 are spaced apart on the support platform 323, with the two support seats 3213 spaced apart along a second direction. A mounting plate 326 is rotatably connected between the two support seats 3213. The output end of the lower cleaning drive member 321 is connected to the mounting plate 326, enabling it to drive the mounting plate 326 to rotate relative to the support platform 323. Multiple lower nozzles 322 are provided, spaced apart along the second direction on the mounting plate 326. When the lower cleaning drive member 321 drives the mounting plate 326 to rotate, it can cause the lower nozzles 322 to lie flat or stand upright. When the lower nozzles 322 are flat, they can avoid moving locomotive air conditioners, preventing unnecessary interference. When the lower nozzles 322 are upright, they can extend into the locomotive air conditioner to clean the internal radiator. In this embodiment, the lower nozzles 322 are long tubular, allowing them to easily extend into the locomotive air conditioner. It should also be noted that moving the lower spray head 322 by rotating the mounting plate 326 saves space compared to moving the lower spray head 322 by direct lifting, making the whole unit more compact.

[0029] For example, a drain outlet 323a is provided on the support platform 323. The drain outlet 323a is located below the mounting plate 326, so that when the nozzle 322 is cleaning, the waste liquid after cleaning will splash down from above, which can be discharged from the drain outlet 323a, reducing the possibility of lateral flow of waste liquid, thereby minimizing the possibility of other parts being splashed with water and extending the service life as much as possible.

[0030] In the current embodiment, the lower cleaning drive component 321 is disposed on the side of the support platform 323 and is offset from the mounting plate 326 in the first direction, thereby reducing the possibility of waste liquid directly splashing onto the lower cleaning drive component 321 and extending its service life. Exemplarily, the lower cleaning drive component 321 is a linear cylinder, with a push rod 3214 connected to the output end of the linear cylinder. The end of the push rod 3214 is hinged to one end of an arc-shaped connecting rod 3215, and the other end of the arc-shaped connecting rod 3215 is hinged to a rotating shaft. The rotating shaft is rotatably connected to the support base 3213 via bearings, and the mounting plate 326 is connected to the rotating shaft, thereby driving the mounting plate 326 to rotate.

[0031] In some embodiments, the lower nozzle 322 is rotatably mounted on the mounting plate 326 via a bearing. A rotary drive 327 is provided on the support platform 323 or the mounting plate 326. The lower nozzle 322 can be selectively connected to the output end of the rotary drive 327. The rotary drive 327 can drive the lower nozzle 322 to rotate relative to the mounting plate 326. Thus, when cleaning, the rotation of the lower nozzle 322 increases the cleaning impact force, further improving the cleaning effect.

[0032] Specifically, continue as Figure 3 and Figure 4As shown, the rotary drive 327 is mounted on the support platform 323. Two first transmission wheels 328 are spaced apart along the second direction on the support platform 323. A flexible member 329 connects the two first transmission wheels 328. A second transmission wheel 3210 is mounted at the output end of the rotary drive 327, and the second transmission wheel 3210 is connected to the flexible member 329. A third transmission wheel 3211 is mounted on each lower nozzle 322. When the lower nozzle 322 is upright, the third transmission wheel 3211 is connected to the flexible member 329, causing the flexible member to... The flexible element 329 can drive the third transmission wheel 3211 to rotate, thereby driving the lower nozzle 322 to rotate. When the lower nozzle 322 is lying flat, the third transmission wheel 3211 disengages from the flexible element 329, and the lower nozzle 322 no longer rotates. Using the flexible element 329 for transmission reduces the number of electrical components. Furthermore, placing the rotating drive element 327 on the support platform 323, compared to directly mounting it on the mounting plate 326, reduces the possibility of the rotating drive element 327 being splashed by wastewater, improving safety and extending its service life. In the current embodiment, the first transmission wheel 328 is located on the lower surface of the support platform 323, while the rotating drive element 327 is located on the upper surface of the support platform 323. The output end of the rotating drive element 327 passes through the support platform 323 to its lower surface, thus placing the second transmission wheel 3210 also on the lower surface of the support platform 323, thereby minimizing the probability of wastewater splashing. It can be understood that the rotating drive element 327 could also be directly mounted on the lower surface of the support platform 323. Of course, to further enhance safety, the rotary drive component 327 and the mounting plate 326 are offset in the first direction. Exemplarily, the first drive wheel 328, the second drive wheel 3210, and the third drive wheel 3211 are all gears, and the flexible component 329 is a chain, which can improve the stability of the transmission. In some alternative embodiments, the flexible component 329 can also be a belt, and the first drive wheel 328, the second drive wheel 3210, and the third drive wheel 3211 can all be rollers that roll in contact with the belt.

[0033] In some embodiments, a rotary joint 3212 is provided on the lower nozzle 322, and the lower nozzle 322 is connected to an external liquid supply pipeline through the rotary joint 3212, which can reduce the possibility of entanglement.

[0034] like Figure 5As shown, in some embodiments, the truss 1 includes two crossbeams 11, which are disposed on both sides of the support rail 23. The crossbeams 11 extend along a first direction, and a moving rail 13 extending in the same direction as the crossbeams 11 is disposed on the crossbeams 11. The transport drive assembly 21 includes a translation drive 211, which is disposed on the crossbeams 11. A moving plate 24 is disposed at the output end of the translation drive 211, and the moving plate 24 is disposed on the moving rail 13. The translation drive 211 drives the moving plate 24 to move on the moving rail 13. A plurality of lifting hooks 22 are spaced apart on the moving plate 24 along the first direction, so that when the lifting hooks 22 hook the locomotive air conditioner, the translation drive 211 can drive it to move along the support rail 23. Exemplarily, the translation drive 211 is a rotary motor, and the output of the rotary motor is provided with a gear. A rack along the first direction is provided on the crossbeams 11, and the gear meshes with the rack to drive the lifting hooks 22 to move.

[0035] In some embodiments, the transport drive assembly 21 further includes a plurality of lifting drive components 212, which are spaced apart on the moving plate 24 along a first direction. The output end of the lifting drive component 212 is provided with a hoisting fixing plate 25, and the hoisting fixing plate 25 is provided with an adjustment rail 26. The moving plate 24 is provided with a slider, which slides on the adjustment rail 26. Thus, the hoisting fixing plate 25 slides on the moving plate 24 through the adjustment rail 26. The hoisting hook 22 is provided on the hoisting fixing plate 25, so the lifting drive component 212 can drive the hoisting hook 22 to rise and fall. On the one hand, it is convenient for the hoisting hook 22 to hook the locomotive air conditioner. On the other hand, the lifting drive component 212 can drive the locomotive air conditioner to rise and fall, so as to facilitate the lower nozzle 322 to extend into the locomotive air conditioner. This reduces the need to add lifting drive components to the lower cleaning assembly 32, minimizes the number of drive components in the lower cleaning assembly 32, reduces the complexity of the lower cleaning assembly 32, reduces the impact of wastewater splashing, and extends the service life as much as possible. For example, a rack can also be provided on the hoisting fixing plate 25, and the lifting drive 212 adopts a rotary motor, with a gear provided at the output end of the rotary motor, and the gear meshing on the rack.

[0036] In the current embodiment, the lifting hook 22 is hinged to the lifting fixing plate 25 via a hinge shaft, which facilitates the adjustment of the lifting hook 22 and thus facilitates hooking.

[0037] Of course, such as Figure 1 As shown, the locomotive air conditioning cleaning device also includes a liquid supply device 4. The liquid supply device 4 is connected to the upper nozzle 312 and the lower nozzle 322 through a liquid supply pipeline, thereby providing cleaning fluid to both. The liquid supply device 4 can be a commonly used device in the prior art, and will not be described in detail.

[0038] like Figure 6As shown, the present invention also provides a cleaning method using the above-mentioned locomotive air conditioner cleaning device, wherein the support rail 23 includes a first position, a second position and a third position in sequence along the moving direction of the locomotive air conditioner. In the current embodiment, the lower nozzle is set at the second position, the first position is located upstream of the second position, and the third position is located downstream of the second position. When the locomotive air conditioner is at the third position, the tail end of the vehicle air conditioner moves past the lower cleaning component 32, causing the locomotive air conditioner and the lower cleaning component 32 to be misaligned. The cleaning method specifically includes the following steps: The locomotive air conditioner moves along the support rail 23 to the contact stopper 324 for positioning; The blocking drive component 325 drives the blocking device 324 to descend, and the translation drive component 211 drives the hoisting hook 22 to move to the locomotive air conditioner, hooks the locomotive air conditioner, and moves the locomotive air conditioner to the first position along the support rail 23 through the translation drive component 211. The upper cleaning drive unit 311 drives the upper nozzle 312 to move, and the upper nozzle 312 cleans the outer shell and internal space of the front half of the locomotive air conditioner. After cleaning, the translation drive 211 moves the lifting hook 22, causing the locomotive air conditioner to continue moving along the support rail 23 to the second position; When the locomotive air conditioner is moved to the second position, the lower nozzle 322 corresponds to the inlet below the locomotive air conditioner. The lifting drive component 212 drives the hoisting hook 22 to rise, so that the locomotive air conditioner is raised, providing space for the lower nozzle 322 to rotate and be lifted. The drive mounting plate 326 rotates, causing the lower nozzle 322 to rise above the support rail 23; the lifting drive component 212 drives the hoisting hook 22 to descend, lowering the locomotive air conditioner so that the lower nozzle 322 can extend into the locomotive air conditioner to clean the radiator. The locomotive air conditioner is driven to rise again, and the lower nozzle 322 descends relative to the supporting rail 23 to reset and avoid the impact. The locomotive air conditioner is placed on the support rail 23, and the lifting hook 22 is moved to the third position by the translation drive component 211; The upper nozzle 312 cleans the rear half of the locomotive air conditioner. Cleaning the rear half of the locomotive air conditioner at this position also reduces the amount of wastewater splashed onto the lower cleaning component 32. After that, it can be drained.

[0039] The above-mentioned cleaning method can improve the cleaning effect compared with manual cleaning. The entire process can be carried out by using the transport drive component 21 to drive the lifting hook 22. Especially when the lower cleaning component 32 enters the interior of the locomotive air conditioner, the locomotive air conditioner can be lifted and lowered by the lifting hook 22, reducing labor intensity and improving cleaning efficiency. Furthermore, by cleaning the locomotive air conditioner in sections, different nozzles and cleaning paths can be used for the front and rear parts of the locomotive air conditioner and the internal radiator, eliminating cleaning blind spots and significantly improving the cleaning effect of deep parts such as the radiator. At the same time, through orderly displacement, lifting and draining, backflow of dirty water and mechanical collision are avoided, sensitive parts are protected and work efficiency is improved.

[0040] 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 can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
