Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicle maintenance, and in particular to a dynamically balanced rubber insulator surface decontamination device and a use method thereof. Background Art

[0002] Currently, my country's penetration rate of high-power locomotives, subways, high-speed trains, and other electric locomotives ranks among the highest in the world. The maintenance of key locomotive components is directly related to the safety of railway assets and the lives of the people. The demand for efficient and fast maintenance is increasing. The rubber insulators on the train roof also need to be cleaned regularly to ensure the clean surface of the rubber insulator and subsequent normal operation.

[0003] Patent publication number CN 108889669 A discloses a highly efficient insulator cleaning device for power maintenance. The device uses the first teeth on the annular rack to drive a rotating gear, thereby driving a rotating plate to reciprocate. The rotation of the rotating plate drives a fixed rod to move, and the oblique bristles clean the recesses of the insulator, while the horizontal bristles clean the outer wall of the insulator.

[0004] Patent publication number CN 111871900 B discloses an air cyclone-type insulator cleaning device. When the airflow is ejected outward, it drives the cleaning ball and the cleaning ball shaft to rotate, forming a rotating airflow. The rotating airflow cooperates with the flexible cleaning tentacles to more effectively remove dirt from the insulator surface.

[0005] However, the rubber insulators on the train roof are different from the ceramic or glass insulators used in the power tower and power grid. Because the rubber insulators travel at high speeds with the train, there is little dust on their surface, but rather a lot of insect remains and sticky stains. These stains cannot be cleaned in the high-speed airflow environment during the train's movement. The above-mentioned cleaning devices use brushes or airflow to clean, which is even less effective in cleaning the stains on the rubber insulator surface.

[0006] In the existing market, the decontamination treatment on the surface of rubber insulators is carried out by relying on manpower. This treatment method has the problems of long operation time, high labor intensity, poor decontamination effect and low safety assurance. Summary of the Invention

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The present invention is provided with a highly flexible, elastic, and non-absorbent cleaning sponge interlayer and a cotton lint cloth. When the cotton lint cloth wrapped in the highly flexible, elastic, and non-absorbent cleaning sponge interlayer is inserted between the annular pieces of the rubber insulator, the cotton lint cloth is squeezed onto the surface of the rubber insulator through the deformation of the highly flexible, elastic, and non-absorbent cleaning sponge interlayer.

Furthermore, a first airbag and a second airbag are provided inside the highly flexible, elastic, and non-absorbent cleaning sponge interlayer to increase the squeezing force, thereby facilitating more stable cleaning of the rubber insulator surface.

[0039] 2. The present invention installs a highly flexible and non-absorbent cleaning sponge interlayer and cotton lint cloth on the cleaning frame, and divides the cleaning frame into two groups. Through the cooperation of the main gear and the arc-shaped rotating plate, the two groups of cleaning frames are driven to rotate synchronously and in opposite directions. On the one hand, full-angle rotation is achieved to wipe the rubber insulator without dead angles, ensuring sufficient cleaning. On the other hand, the friction torque of the upper and lower parts offsets each other, improving the stability of the equipment operation and avoiding the instability of the equipment caused by unidirectional movement.

[0040] 3. The present invention also provides an automatic locking mechanism. During installation, the rubber insulator pushes the connecting rod, driving the movable half-ring to move, closing the movable half-ring and the fixed half-ring to form a support ring. The support ring is sleeved on the top of the rubber insulator. On the one hand, it supports the main frame and the cleaning frame, making it easier to hold. On the other hand, it facilitates the purpose of self-fixing and locking, improving the convenience and automation of operation. Furthermore, a processing unit, a battery power supply, a camera, and a speed and position sensor are provided. The user only needs to pass the rubber insulator through the first and second notches, and subsequent fixing, cleaning, and cleaning after cleaning can be automatically performed.

[0041] 4. The arc-shaped rotating plate and the arc-shaped mounting plate are fixedly connected by a quick-release structure. By inserting the two fixing pins to the left and right, the remaining fixing pin can be swung into the pin-mounting groove and locked by the locking plate, which has the function of one-button disassembly and assembly, and can quickly replace the cleaning skeleton and cleaning mechanism, which is convenient for periodic inspection and maintenance; in addition, an extension tube and a first grip rod are provided on the main frame. The first grip rod can be gripped to push the main frame and related components toward the rubber insulator side, and two second grip rods connected to the main frame are provided on both sides of the extension tube. The user can also grip the two second grip rods, which further improves the convenience of the gripping operation.

[0067] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0068] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0069] Example 1

[0070] Please refer to Figures 1 to 11 The embodiment of the present invention provides a surface cleaning device for a dynamically balanced rubber insulator, comprising:

[0071] The cleaning skeleton 4 includes a plurality of arc-shaped mounting plates 43 evenly arranged along a first direction, each arc-shaped mounting plate 43 has a first notch, each arc-shaped mounting plate 43 takes the first axis as the central axis, and the extending direction of the first axis is the first direction, wherein the first direction is Figure 1 The vertical direction in

[0072] A plurality of cleaning mechanisms 6, including a plurality of highly flexible, elastic, and non-absorbent cleaning sponge interlayers 61 mounted on the outside of the arc-shaped mounting plate 43, the highly flexible, elastic, and non-absorbent cleaning sponge interlayers 61 being wrapped with cotton flannel 62, and a pressurizing component being provided inside the highly flexible, elastic, and non-absorbent cleaning sponge interlayers 61 for applying outward pressure to the highly flexible, elastic, and non-absorbent cleaning sponge interlayers 61;

[0073] A driving mechanism for driving the cleaning frame 4 to rotate about the first axis, thereby driving the lint cloth 62 to wipe the outer surface of the rubber insulator 5;

[0074] like Figures 1 to 7 As shown, several arc-shaped mounting plates 43 are disassembled and inserted between the annular pieces of the rubber insulator 5, and the high-soft elastic non-water-absorbent cleaning cotton interlayer 61 is squeezed by the booster component, so that the high-soft elastic non-water-absorbent cleaning cotton interlayer 61 pushes the cotton flannel 62 to adhere tightly to the outer surface of the rubber insulator 5 and applies an extrusion force. As the extrusion force increases, the cotton flannel 62 rotates with the cleaning frame 4, and the friction between it and the outer surface of the rubber insulator 5 increases, which directly increases the shear force on the stains, especially for firmly attached dirt (such as dried oil stains and insect remains). The width of the first notch is smaller than the outer diameter of the central column of the rubber insulator 5 to ensure that it can be inserted between each arc-shaped mounting plate 43. Compared with manual cleaning in the prior art, the cooperation of multiple arc-shaped mounting plates 43 and cotton flannel 62 can achieve more efficient cleaning efficiency and higher standards of cleanliness, and solves the problem that the existing ceramic or glass insulators cannot clean the rubber insulators on the train roof.

[0075] In some embodiments, a plurality of mounting notches 45 are disposed around the arc-shaped mounting plate 43. The additional component includes a first airbag 64 disposed above the arc-shaped mounting plate 43 and a second airbag 65 disposed below the arc-shaped mounting plate 43. The first airbag 64 and the second airbag 65 are detachably connected at positions corresponding to the mounting notches 45 by a second adhesive member 66.

[0076] like Figure 6 and Figure 7 As shown, during assembly, the first airbag 64 and the second airbag 65 can be assembled through the second adhesive member 66 and the installation notch 45 to achieve the initial installation of the two. The installed first airbag 64 and the second airbag 65 are inflated. After expansion, the highly flexible elastic non-water-absorbent clean cotton interlayer 61 is pushed outward to increase the friction between the cotton flannel 62 and the surface of the rubber insulator 5. Furthermore, a reserved groove 67 is provided inside the highly flexible elastic non-water-absorbent clean cotton interlayer 61 to fit with the first airbag 64 and the second airbag 65. On the one hand, the first airbag 64 and the second airbag 65 serve to limit the position of the highly flexible elastic non-water-absorbent clean cotton interlayer 61, and on the other hand, On the one hand, it also avoids excessive compression of the highly soft, elastic, and non-absorbent cleaning cotton interlayer 61, which causes loss of its elastic properties; further, the inner edge of the cotton flannel cloth 62 can be detachably connected to the arc-shaped mounting plate 43 through the first adhesive 63, and the highly soft, elastic, and non-absorbent cleaning cotton interlayer 61 can also be detachably connected to the cotton flannel cloth 62 or the arc-shaped mounting plate 43 through the third adhesive; optionally, the first adhesive 63, the second adhesive 66 and the third adhesive can all be made of Velcro; further optionally, air nozzles are reserved on the surfaces of the first airbag 64 and the second airbag 65 for inflation.

On the one hand, it realizes full-angle rotation to wipe the rubber insulator 5 without dead angles, ensuring sufficient cleaning.

When the driving component 3 drives the main gear 24 to rotate, it is restricted by the supporting guide wheel 23, thereby ensuring the stable rotation of the arc-shaped rotating plate 21, wherein the number of supporting guide wheels 23 is at least three and evenly distributed on the edge of the arc-shaped groove 15; optionally, the lower support plate 11 and the upper support plate 12 are provided with a first guide wheel column 25 and a second guide wheel column 27 at the edge of the arc-shaped groove 15, and the supporting guide wheel 23 can be directly mounted on the first guide wheel column 25, and the two ends of the second guide wheel column 27 are respectively connected to the lower support plate 11 and the upper support plate 12, and a first separating cylinder 26 is provided in the middle, and the two ends of the first separating cylinder 26 are provided with supporting guide wheels 23 mounted on the second guide wheel column 27. The second guide wheel column 27 not only has the function of installing and supporting the guide wheel 23, but also can fix the lower support plate 11 and the upper support plate 12. Furthermore, an I-shaped support block 13 is installed between the ends of the lower support plate 11 and the upper support plate 12 near the first notch by bolts and nuts, and a first mounting column 16 is installed in the middle of the lower support plate 11 and the upper support plate 12 by stud nuts, which serves the purpose of reinforcing the main frame 1 and improving the structural stability of the main frame 1. Furthermore, the I-shaped support block 13 extends near the second notch to form a guide groove 14, and the inner wall of the guide groove 14 and the inner wall of the annular groove both fit with the arc-shaped rotating plate 21, further improving the support and restriction effect on the arc-shaped rotating plate 21, and ensuring the stability of the rotation of the arc-shaped rotating plate 21.

Furthermore, the transmission structure is outer-covered with a protective shell 34, which is installed at the top of the upper support plate 12 to protect the transmission structure. Preferably, the input shafts of the two commutators 32 can be provided with small gears, and the output shaft of the motor 31 is provided with a large gear. The two small gears are respectively on both sides of the large gear and are meshed with the large gear for transmission connection.

[0086] In some embodiments, the cleaning frame 4 is detachably connected to the arc-shaped rotating plate 21 via a quick-install structure 7. The cleaning frame 4 includes a special-shaped semicircular ring 41 provided on the inner circle of the arc-shaped rotating plate 21. The quick-install structure 7 includes three fixing pins 71 evenly arranged around the outer wall of the special-shaped semicircular ring 41.

[0087] The two fixing pins 71 extend along the second direction, and the inner wall of the arc-shaped rotating plate 21 is provided with pin holes 72 at positions corresponding to the two fixing pins 71;

A mounting shaft 75 is provided inside the hole 74, and the top of the mounting shaft 75 is connected to the bottom of the locking plate 76. The bottom of the locking plate 76 is also provided with a limit member 77 that can be inserted into the locking hole 78. A knob 79 is provided at the top of the locking plate 76. By rotating the knob 79, the locking plate 76 rotates around the mounting shaft 75, driving the limit member 77 to disengage from the locking hole 78, thereby realizing the purpose of transforming the locking plate 76 from closing the pin-mounted slot 73 to exposing the pin-mounted slot 73. This method is simple, convenient and efficient to operate. It is further preferred that the limit member 77 is made of rubber material or a spring top bead.

Furthermore, positioning is also achieved after mounting, which is convenient for subsequent cleaning.

[0092] In some embodiments, the automatic locking mechanism 8 includes a fixed half ring 83 fixedly connected to the main frame 1, one end of the fixed half ring 83 is rotatably connected to a movable half ring 86 via a connecting shaft 810, and both the movable half ring 86 and the fixed half ring 83 are provided with a first protrusion 88 at the end away from the connecting shaft 810, one of the first protrusions 88 is provided with a micro-servo 84, and a rotating clamping plate 85 is mounted on the output shaft of the micro-servo 84, and a closed-loop sensor 89 is provided on the other first protrusion 88, and the output end of the closed-loop sensor 89 is electrically connected to the input end of the micro-servo 84;

[0093] The top of the connecting shaft 810 is further provided with a connecting rod 87 tangentially connected to the movable half ring 86. When the movable half ring 86 and the fixed half ring 83 are closed, the connecting rod 87 extends toward the side away from the second notch.

[0094] like Figure 8 、 Figure 9 and Figure 10 As shown, the user pushes the main frame 1 to move toward the rubber insulator 5. During this process, the rubber insulator 5 will push the connecting rod 87, driving the movable half ring 86 to rotate around the connecting shaft 810 until the two first protrusions 88 fit together. At this time, the closed-loop sensor 89 detects that the two first protrusions 88 fit together, and the micro-servo 84 will be started. The rotating clamping plate 85 on the output shaft of the micro-servo 84 rotates to clamp the first protrusion 88 of the movable half ring 86 to achieve the purpose of automatic locking. In addition to providing a supporting effect after locking, it provides an accurate positioning effect. After automatic locking, it means that the rubber insulator 5 has entered the specified position, realizing the positioning of subsequent cleaning and avoiding the situation of inadequate cleaning. Optionally, the movable half ring 86 and The fixed half ring 83 extends near the connecting shaft 810 to form a second protrusion 812, and the connecting shaft 810 is installed in the middle of the two second protrusions 812. In addition, a torsion spring 811 is provided on the connecting shaft 810, and its two ends are respectively connected to the movable half ring 86 and the fixed half ring 83. When the micro-servo 84 resets the rotating clamping plate 85 and the rubber insulator 5 leaves the fixed half ring 83, the movable half ring 86 and the connecting rod 87 will be driven to reset under the action of the torsion spring 811, waiting for the next cleaning; in addition, a longitudinal compensation rod 81 is installed on the top of the protective shell 34 provided on the main frame 1, and a horizontal compensation rod 82 is provided on the top of the longitudinal compensation rod 81, which ultimately ensures that the fixed half ring 83 is located above the cleaning skeleton 4, ensuring that the axis of the support ring coincides with the first axis.

[0095] In some embodiments, the main frame 1 is further provided with a gripping mechanism 9, which includes a fixing frame 91 disposed between the lower support plate 11 and the upper support plate 12 and away from the second notch end. The fixing frame 91 is provided with a mounting sleeve 92 at the end away from the second notch. An extension tube 93 extending upward toward the side away from the second notch is installed inside the mounting sleeve 92, and a first gripping rod 94 is installed at the top of the extension tube 93.

[0096] The holding mechanism 9 includes a second holding rod 95 provided on both sides of the fixing frame 91. The axis direction of the second holding rod 95 is the first direction, and the second holding rod 95 is detachably connected to the lower support plate 11 and the upper support plate 12 respectively.

[0097] like Figure 1 and Figure 11The holding mechanism 9 provides two holding methods. When the rubber insulator 5 on the top of the train is lower, the user can move the main frame 1 by holding the first holding rod 94. When the rubber insulator 5 on the top of the train is higher, it is necessary to first remove the extension tube 93 and the first holding rod 94, and operate by holding the two second holding rods 95 with both hands respectively, so that flexible operation can be achieved according to the position of the rubber insulator 5 on the roof of the train.

[0098] In some embodiments, the decontamination device further includes an intelligent control component, which includes a power supply unit and a processing unit disposed inside the protective shell 34. A camera 101 is disposed on the top of the protective shell 34, and the camera 101 is used to photograph the surface of the rubber insulator 5. The main frame 1 is also provided with a speed and position sensor 103 for detecting the position of the first notch of the arc-shaped mounting plate 43.

[0099] The processing unit is electrically connected to the power supply unit, the camera 101 and the rotation speed and position sensor 103 respectively.

[0100] like Figures 1 to 11 As shown, the closed-loop sensor 89 and the micro-servo 84 are electrically connected through the processing unit. When the closed-loop sensor 89 detects that the movable half-ring 86 and the fixed half-ring 83 are in contact, the information is transmitted to the processing unit, and the processing unit sends a closed signal to the micro-servo 84, so that the rotating clamping plate 85 on the output shaft of the micro-servo 84 rotates, clamping the first protrusion 88 of the movable half-ring 86 to achieve automatic locking; at the same time, the processing unit controls the motor 31 to rotate, thereby driving the main gear 24 to rotate, and the main gear 24 drives the two arc-shaped rotating plates 21 and the two sets of cleaning skeletons 4 to rotate synchronously in the opposite direction, using the cotton lint cloth 62 installed on the cleaning skeleton 4 to clean the rubber The surface of the insulator 5 is wiped, and during the wiping process, the camera 101 captures an image of the surface of the rubber insulator 5 and transmits it to the processing unit. The processing unit is internally provided with a deep learning image recognition algorithm. The image recognition algorithm is a prior art and will not be described in detail here. When it is recognized that the stain area is lower than a threshold value, it means that it has been cleaned. At this time, the processing unit will shut down the motor 31. During the shutdown period, the speed and position sensor 103 will be used to detect the position of the cotton wool cloth 62 to ensure that the first gap still corresponds to the second gap after the shutdown, so that the rubber insulator 5 can pass smoothly. After the shutdown is completed, the processing unit controls the micro-servo 84 to reset and wait for the next cleaning operation.

[0101] In some embodiments, a display screen is provided on the protective shell 34, which is used to display the remaining power and warning signal of the power supply unit. A posture detection sensor 102 is also provided on the top of the protective shell 34 to monitor the vibration of the equipment. A pressure sensor 104 is provided inside the high-soft, elastic, non-absorbent cleaning cotton interlayer 61. The pressure sensor 104 is used to monitor the feedback pressure of the rubber insulator 5. The posture detection sensor 102 and the pressure sensor 104 are both electrically connected to the processing unit. When the signal is lower than the preset value, the processing unit controls the display screen to display the corresponding warning signal, such as "insufficient pressure" or "rotation posture error".

[0102] In some embodiments, the closed-loop sensor 89 uses a magnet to attract and conduct to determine whether it is closed. The posture detection sensor 102 uses a gravity sensor to determine whether the device is severely tilted. The speed and position sensor 103 uses a Hall sensor to realize the statistics of the speed and calculates the rotation position through a control algorithm. When the device stops operating, it ensures that the opening position direction under the first notch and the second notch is consistent.

[0103] Example 2

[0104] Based on Example 1, Figure 12 This embodiment provides a method for using a dynamically balanced rubber insulator surface cleaning device, which specifically includes the following steps:

[0105] S1. Operate the holding mechanism 9 to align the first notch and the second notch with the rubber insulator 5;

[0106] S2. Move the main frame 1 so that the lint cloth 62 is inserted between the annular pieces of the rubber insulator 5.

[0107] S3, when the rubber insulator 5 pushes the connecting rod 87, driving the movable half ring 86 and the fixed half ring 83 to merge, the micro-servo 84 is started to lock;

[0108] S4, start the driving assembly 3, the driving assembly 3 drives the main gear 24 to rotate, driving the two arc-shaped rotating plates 21 to move synchronously in opposite directions, and the lint cloth 62 performs the cleaning operation;

[0109] S5, the camera 101 captures the surface of the rubber insulator 5 to obtain a real-time image, and the processing unit identifies the stain area in the image. If the stain area is smaller than a threshold, the next step is executed. If not, the lint cloth 62 continues to perform the cleaning operation;

[0110] S6, the speed and position sensor 103 detects the position of the first notch, and when the first notch coincides with the second notch, the drive assembly 3 and the micro-servo 84 are shut down;

[0111] S7. Operate the holding mechanism 9 to separate the rubber insulator 5 from the first notch and the second notch.

[0112] The direct operations of step S3 and step S6 can be transmitted and processed by the processing unit to achieve the purpose of automatic cleaning. The user actually only needs to pass the rubber insulator 5 through the first gap and the second gap, which greatly improves the cleaning efficiency.
