Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to an intelligent cleaning and storage method and equipment for commonly used locomotive maintenance tools. Background Technology

[0002] In the maintenance of rail transit vehicles, handheld maintenance tools such as wrenches, measuring tapes, electronic calipers, hydraulic torque wrenches, screwdrivers, and hammers are essential and readily available tools for daily locomotive maintenance. These tools are used frequently in diverse environments, ranging from dusty and oil-contaminated areas like the running gear and roof to the sealed environments of precision circuits within the locomotive's interior. Existing tool storage cabinets only provide storage; cleaning requires removing the tools and placing them in separate cleaning boxes, which is inconvenient. Furthermore, cleaning tools in the box followed by returning them to the storage cabinet wastes manpower and can easily cause secondary contamination of the cleaned tools. Summary of the Invention

[0003] In view of the above-mentioned defects or deficiencies in the existing technology, it is desirable to provide an intelligent cleaning and storage method and equipment for locomotive maintenance tools, so as to achieve integrated cleaning and storage, save labor costs, extend tool life, and improve cleaning efficiency.

[0004] This application provides an intelligent cleaning and storage device for commonly used maintenance tools, comprising:

[0005] The storage cabinet has a storage station and a cleaning station. The storage station is equipped with a tray, and the cleaning station is equipped with a dry ice cleaning nozzle.

[0006] A first driving mechanism is provided in the cleaning station to drive the tray to move from the storage station to above or below the dry ice cleaning nozzle.

[0007] The second drive mechanism is located within the cleaning station and is used to drive the dry ice cleaning nozzle to rotate so that the dry ice cleaning nozzle faces upward or downward.

[0008] The first drive mechanism includes a lifting component disposed within the cleaning station and a traction component disposed on the lifting component;

[0009] The lifting assembly is capable of lifting within the cleaning station, including a lifting platform of the same size as the tray, set on the cleaning station, and two vertical first supports of the same height as the storage cabinet. A roller is installed between the tops of the two first supports, and a lifting belt is attached to the outer periphery of the roller. One end of the lifting belt is wound around the shaft at the output end of the control motor, and the other end is fixedly connected to one side of the lifting platform. A sliding assembly is integrally formed on the same side of the lifting platform, and the sliding assembly is sleeved on the first support and slidably connected to the first support.

[0010] The traction assembly is used to move the tray from the storage station to the cleaning station. It includes a traction plate disposed on the lifting platform. Infrared positioning sensors are disposed at both ends of the traction plate for sensing and positioning. An electromagnet is disposed on the side of the traction plate near the tray for attracting the tray to an electromagnet adsorption block on the side of the tray. The top of the two crossbeams of the lifting platform is provided with slide rails. A first lead screw is disposed on the outer side of the crossbeams. A first reduction motor is disposed at one end of the first lead screw to drive its rotation. The two ends of the traction plate are threaded onto the first lead screw.

[0011] Furthermore, the second driving mechanism includes a horizontal moving component disposed within the cleaning station and a flipping component disposed on the horizontal moving component, wherein the dry ice cleaning nozzle is connected to the flipping component; the horizontal moving component is used to drive the flipping component to move horizontally along its extension direction, and the flipping component is used to drive the dry ice cleaning nozzle to flip.

[0012] Furthermore, a vacuum cleaner and a third drive mechanism are provided at the bottom of the cleaning station. The third drive mechanism is connected to the vacuum cleaner and is used to drive the vacuum cleaner to move at the bottom of the cleaning station to absorb impurities generated during the cleaning process.

[0013] Furthermore, a first visual recognition system is installed above the tray within the storage station.

[0014] Furthermore, a second visual recognition system is installed in the cleaning station near the dry ice cleaning nozzle.

[0015] Furthermore, the tray is provided with stainless steel mesh; pulleys are provided at the four corners of the bottom of the tray; and an electromagnet adsorption block is provided on the side of the tray closest to the cleaning station.

[0016] The present invention provides a method for cleaning and storing commonly used locomotive maintenance tools, comprising the following steps:

[0017] After the first vision recognition system detects that there are tools in the tray and the type of tools is verified to be correct, it controls the first drive mechanism to move the tray above or below the dry ice cleaning nozzle.

[0018] Control the second drive mechanism to make the dry ice cleaning nozzle face up or down, and start the dry ice cleaning nozzle to clean the tool;

[0019] After cleaning the upper and lower surfaces of the tool, control the first drive mechanism to move the tray to the storage station.

[0020] Furthermore, during the cleaning process, the second drive mechanism is controlled based on the recognition results of the second vision recognition system to control the horizontal movement position of the dry ice cleaning nozzle.

[0035] 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, only the parts relevant to the invention are shown in the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Please refer to Figures 1-3 Embodiments of the present invention provide an intelligent cleaning and storage device for commonly used locomotive maintenance tools, comprising:

[0038] Storage cabinet 1 has a storage station 2 and a cleaning station 3. Storage station 2 is equipped with a tray 21, and cleaning station 3 is equipped with a dry ice cleaning nozzle 31.

[0039] The first drive mechanism 4 is located in the cleaning station 3 and is used to drive the tray 21 to move from the storage station 2 to above or below the dry ice cleaning nozzle 31.

[0040] The second drive mechanism 5 is located in the cleaning station 3 and is used to drive the dry ice cleaning nozzle 31 to rotate so that the dry ice cleaning nozzle 31 faces upward or downward.

[0041] In this embodiment, the storage cabinet 1 is divided into two parts: a storage station 2 and a cleaning station 3. The storage station 2 and the cleaning station 3 are connected. The maintenance tools are placed on the tray 21 of the storage station 2. The first drive mechanism 4 is located in the cleaning station 3 and includes a lifting platform of the same size as the tray 21. The first drive mechanism 4 is used to pull and move the tray horizontally and vertically. The second drive mechanism 5 is also located in the cleaning station 3 and is used to flip the dry ice cleaning nozzle 31. When cleaning the maintenance tools, the dry ice cleaning nozzle 31 avoids the first drive mechanism 4. Then the first drive mechanism 4 is activated and moves upward or downward, through its red light... The external positioning sensor locates the tray 21 containing the maintenance tool that needs cleaning. Then, an electromagnet attracts the electromagnet adsorption block on the tray 21 and pulls it to move the tray 21 from the storage station 2 to the cleaning station 3. Then, the first drive mechanism 4 moves the tray 21 above the dry ice cleaning nozzle 31 to clean the bottom of the maintenance tool. Then, the first drive mechanism 4 moves the tray 21 below the dry ice cleaning nozzle 31. The second drive mechanism 5 flips the dry ice cleaning nozzle 31 so that it faces downwards to clean the top of the maintenance tool. After cleaning, the first drive mechanism 4 moves the maintenance tool to the storage station 2 for storage.

[0042] In a preferred embodiment, such as Figure 2 As shown, the first drive mechanism 4 includes a lifting component 41 disposed in the cleaning station 3 and a traction component 42 disposed on the lifting component 41; the lifting component 41 can be lifted and lowered within the cleaning station 3, and the traction component 42 is used to move the tray 21 from the storage station 2 to the cleaning station 3.

[0043] In this embodiment, the first drive mechanism 4 includes a lifting assembly 41 disposed in the cleaning station 3 and a traction assembly 42 disposed on the lifting assembly 41;

[0044] The lifting assembly 41 includes a lifting platform of the same size as the support frame 21, which is set on the cleaning station 3, and two vertical first supports that are the same height as the storage cabinet 1. A roller is installed between the tops of the two first supports, and a lifting belt is attached to the outer periphery of the roller. One end of the lifting belt is wound around the shaft of the control motor output end, and the other end is fixedly connected to one side of the lifting platform. A sliding assembly is integrally formed on the same side of the lifting platform. The sliding assembly is sleeved on the first support and slidably connected to the first support, so that the lifting platform can maintain balance.

[0045] The traction assembly 42 includes a traction plate set on the lifting platform. Infrared positioning sensors are set at both ends of the traction plate for sensing and positioning. An electromagnet is set on the side of the traction plate near the support frame 21 for adsorption with an electromagnet adsorption block on the side of the support frame 21. The top of the two crossbeams of the lifting platform is provided with slide rails. A first lead screw is set on the outside of the crossbeams. A first reduction motor is set at one end of the first lead screw to drive its rotation.

[0046] When cleaning the maintenance tools, the motor is controlled to rotate, which drives the lifting belt to wind or unwind, thereby raising or lowering the lifting platform that is fixedly connected to the lifting belt. The sliding assembly is equipped with multiple sets of pulleys, and the first bracket is equipped with a slide rail for the pulleys to slide on, which can ensure that the lifting platform can move smoothly up or down. The infrared positioning sensor can detect the support frame 21 where the maintenance tool to be cleaned is located, and the lifting platform stops moving. Then, the electromagnet on the traction plate attracts the electromagnet attraction block on the support frame 21. The two ends of the traction plate are threaded onto the first lead screw. Then, the first reduction motor is started, and the lead screw drives the traction plate to move the support frame 21 to the cleaning station 3.

[0047] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the second drive mechanism 5 includes a horizontal moving component 51 disposed in the cleaning station 3 and a flipping component 52 disposed on the horizontal moving component 51. The dry ice cleaning nozzle 31 is connected to the flipping component 52. The horizontal moving component 51 is used to drive the flipping component 52 to move horizontally along its extension direction, and the flipping component 52 is used to drive the dry ice cleaning nozzle 31 to flip.

[0048] In this embodiment, the second drive mechanism 5 includes a horizontal moving component 51 disposed within the cleaning station 3 and a flipping component 52 disposed on the horizontal moving component 51. A second support is disposed within the cleaning station 3, and a first slider is disposed on the top of the second support. The horizontal moving component 51 includes a second lead screw disposed within a slide groove on the top of the second support. A second reduction motor is disposed at one end of the second lead screw to drive its rotation. The first slider is threaded onto the second lead screw. When the second reduction motor is activated, the dry ice cleaning nozzle 31 can move horizontally along the extension direction of the second support, allowing for cleaning of different positions of the maintenance tools. A 90-degree rotatable mounting block is disposed on the top of the first slider to avoid obstacles when the lifting platform is raised or lowered. The top of the mounting block is equipped with a flipping assembly 52, which includes a servo motor and a mounting plate. A dry ice cleaning nozzle 31 is mounted on one end of the mounting plate. The servo motor rotates to drive the mounting plate to flip 180 degrees, allowing the dry ice cleaning nozzle to be adjusted to face up or down, facilitating cleaning from both the top and bottom of the maintenance tool. A third lead screw is installed in the slide groove of the mounting plate, and a third reduction motor is installed in the servo motor to drive the third lead screw to rotate. A slider is installed in the slide groove that is threaded onto the third lead screw. When the third reduction motor is started, it drives the third lead screw to rotate, which in turn drives the dry ice cleaning nozzle 31 to move along the extension direction of the mounting plate, allowing cleaning of different positions of the inspection tool and improving the cleaning effect of the maintenance tool.

[0049] In a preferred embodiment, such as Figure 2 As shown, a vacuum cleaner 32 and a third drive mechanism 6 are provided at the bottom of the cleaning station 3. The third drive mechanism 6 is connected to the vacuum cleaner 32 and is used to drive the vacuum cleaner 32 to move at the bottom of the cleaning station 3 to absorb impurities generated during the cleaning process.

[0050] In this embodiment, a vacuum cleaner 32 and a third drive mechanism 6 are provided at the bottom of the cleaning station 3. The third drive mechanism includes a fourth lead screw located at the bottom of the cleaning station and a fourth reduction motor that drives it to rotate. A slider is threaded onto the fourth lead screw, and the bottom of the slider contacts the inside of the storage cabinet. One end of the slider is connected to the vacuum cleaner. When cleaning the maintenance tools, the vacuum cleaner is moved by the lead screw drive to adsorb the impurities generated during the cleaning process. The vacuum cleaner stops working 2 minutes after the cleaning is completed.

[0051] In a preferred embodiment, such as Figure 1 As shown, a first visual recognition system 22 is installed above the tray 21 in the storage station 2.

[0052] In this embodiment, a first visual recognition system 22 is electrically connected above the tray 21 in the storage station 2. The first visual recognition system 22 identifies the type of maintenance tool in the tray 21. After verifying that it is correct, the storage cabinet closes to complete the storage.

[0053] In a preferred embodiment, such as Figure 3 As shown, a second visual recognition system 33 is installed in the cleaning station 3 near the dry ice cleaning nozzle 31.

[0054] In this embodiment, a second vision recognition system 33 is installed near the dry ice cleaning nozzle 31 in the cleaning station 3. When cleaning the maintenance tools on the tray 21, the outline of the maintenance tools is scanned by the second vision recognition system 33, and then the horizontal moving component 51 is moved by the controller so that the dry ice cleaning nozzle 31 is aligned with the maintenance tools for comprehensive cleaning.

[0055] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the frame 21 is provided with stainless steel mesh; pulleys are provided at the four corners of the bottom of the frame 21; and an electromagnet adsorption block 23 is provided on the side of the frame 21 near the cleaning station 3.

[0056] In this embodiment, the frame 21 is provided with stainless steel mesh to facilitate the falling of impurities into the frame 21 during the cleaning process; pulleys are provided at the four corners of the bottom of the frame 21 to facilitate the movement of the frame 21 during traction; an electromagnet adsorption block 23 is provided on the side of the frame 21 near the cleaning station 3 to adsorb and fix the frame 21, preventing the frame 21 from falling off the traction plate during movement.

[0057] This application provides a method for cleaning and storing commonly used locomotive maintenance tools, utilizing an intelligent cleaning and storage device for commonly used locomotive maintenance tools disclosed in the above embodiments. Please refer to... Figure 4 The cleaning and storage method includes the following steps:

[0058] S001, after the first visual recognition system 22 detects that there is a tool in the tray 21 and the type of the tool is verified to be correct, it controls the first drive mechanism 4 to move the tray 21 above or below the dry ice cleaning nozzle 31.

[0060] S003, after cleaning the upper and lower surfaces of the tool, control the first drive mechanism 4 to move the tray 21 to the storage station 2.

[0061] In this embodiment, after the first visual recognition system 22 detects that tools are stored in the tray 21 and the type of tools is verified to be correct, the storage cabinet closes to achieve storage. When it is necessary to clean the maintenance tools, the first drive mechanism 4 is controlled to pull the tray 21 to the cleaning station 3, so that the first drive mechanism 4 moves the tray 21 above the dry ice cleaning nozzle 31; the second drive mechanism 5 is controlled to make the dry ice cleaning nozzle 31 face upward, and the maintenance tools are identified by the second visual recognition system 33, and the second drive mechanism 5 is controlled to achieve water cleaning of the dry ice cleaning nozzle 31. The tool is moved horizontally to clean the underside of the repair tool. Then, the first drive mechanism 4 moves the support frame 21 below the dry ice cleaning nozzle 31. The second drive mechanism 5 is controlled so that the dry ice cleaning nozzle 31 faces downwards to clean the top of the repair tool. During the cleaning process, the vacuum cleaner 32 is started, and the third drive mechanism 6 is controlled to drive the vacuum cleaner 33 to move, so as to achieve the cleaning operation of the cleaning station 3. After the upper and lower surfaces of the tool are cleaned, the first drive mechanism 4 is controlled so that the support frame 21 moves to the storage station 2.
