Description

[0002] Nowadays, the urban rail system is developing rapidly, and the demand for carbon slide plates of the pantograph of the urban rail system is also increasing rapidly, and the service life of the carbon slide plate has attracted more attention. The pantograph-catenary system is a complex electromechanical dynamic system composed of the elastic suspension system of the catenary contact line and the elastic system of the train pantograph, and the sliding contact between the carbon slide plate and the catenary line.

[0003] The pantograph completes current collection and transmits it to the train through the sliding contact with the catenary line through the carbon slide plate. However, the high-speed sliding contact between the carbon slide plate and the catenary line often causes the carbon slide plate to wear out, and if it is not replaced in time, it will pose a great risk to the safety of rail operation. Therefore, it is necessary to detect the abrasion of the carbon slide plate of the pantograph during vehicle maintenance.

[0004] There are mainly two kinds of measurement methods on the market at present. One is to use a vernier caliper and other tools to measure manually, which is not only slow but also has low measurement accuracy, and the subsequent data statistics are also troublesome. The other is to use an intelligent detection device to automatically measure, which needs to add a roller walking driving mechanism to drive a detection device equipped with related detection devices to move along the carbon slide plate to complete the detection. This results in that the volume and weight of the detection device are too large, and it is inconvenient to carry the detection device as an online regular inspection equipment. Moreover, the face laser sensor is used to scan the entire top surface of the carbon slide plate, and the amount of data collected is large, and there is a lot of useless data, which reduces the speed of subsequent abrasion detection processing and has low real-time performance.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the following embodiments are combined with the drawings to specifically describe the portable carbon slide plate wear intelligent detector of the present application. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application.

[0021] Considering the actual use state of the carbon slide plate, it is often matched with a rigid contact line at a certain inclination angle to realize power transmission of the catenary to the running train, and the wear surface is mostly inclined, and the corresponding wear cross section is mostly inclined. Therefore, the present application provides a portable carbon slide plate wear intelligent detector. The hand-pushed detector moves along the length direction of the carbon slide plate, and in this process, distance information of the highest point and the lowest point corresponding to the effective detection area of the carbon slide plate is collected at equal intervals from both sides of the length center line of the carbon slide plate at the same time, so as to realize detection of the remaining thickness and the eccentric wear angle of the carbon slide plate. At the same time, the detection position points and the abnormal position points of the carbon slide plate are photographed by the camera, and a detection report is generated together to give maintenance suggestions and upload to the control center / remote server. In this way, during the hand-pushing process, the distance information of the highest point and the lowest point corresponding to the current cross section is measured by two laser ranging sensors at the same time, so that the wear condition of the current cross section can be roughly known. After the equal-interval distance information collection, the wear condition of the entire carbon slide plate can be obtained. Compared with the existing wear detection method, the data amount participating in the wear calculation can be greatly reduced, the calculation speed of the wear detection can be accelerated, the real-time performance is higher, the response speed is faster, and the work efficiency can be improved.

[0022] Specifically as follows: As Figures 1-2 The portable carbon slide plate abrasion intelligent detector of the present application adopts a layered structure and comprises, from top to bottom, a handle 1, a detection unit 2 and a clamping unit 3. The detection unit 2 is used for abrasion detection of the carbon slide plate. The clamping unit 3 adopts a wrapping type structure to clamp the carbon slide plate and comprises a plurality of reference wheels 301 arranged at the bottom of the carbon slide plate, a plurality of fixed guide wheels 302 arranged at the two sides of the carbon slide plate and a plurality of movable guide wheels 303 arranged at the top surface of the carbon slide plate. The reference wheels 301 are connected with a scissor type telescopic mechanism 304 which is used for controlling the extension and retraction of the reference wheels 301 to realize the wrapping type clamping of the carbon slide plate. The movable guide wheels 303 are connected with an adaptive adjusting mechanism which is used for ensuring that the movable guide wheels 303 are always in contact with the top surface of the carbon slide plate and the reference wheels 301 are always in contact with the bottom surface of the carbon slide plate. In this way, the detector is clamped on the carbon slide plate by means of the clamping unit 3, and then the handle is gripped to drive the detector to move along the carbon slide plate, so that the detection unit 2 can complete the parameter detection of the entire carbon slide plate without the need for additional roller walking driving mechanism, which can reduce the volume and weight of the entire device to a certain extent, help to increase the portability, and have stronger practicability and can meet the needs of online regular inspection of the carbon slide plate.

[0023] As Figures 3-5 , 10 shows that the entire detector is divided into three layers, including the handle 1 of the upper layer, the detection unit 2 of the middle layer and the clamping unit 3 of the lower layer. The clamping unit 3 has an overall inverted U-shaped structure and forms a wrapping type clamping for the cross section of the carbon slide plate. The clamping unit 3 is convenient for clamping and can ensure the rolling cooperation of the reference wheels 301 and the guide wheels with the carbon slide plate, which provides protection for the smooth movement of the detector along the carbon slide plate by the staff and helps to improve the use experience.

[0024] In order to facilitate clamping, the present application designs a scissor type telescopic mechanism 304. The scissor type telescopic mechanism 304 comprises two moving frames 3041 arranged symmetrically. The top surface of each moving frame 3041 at the front and rear ends is provided with a connecting handle 3042 extending to the center. The two connecting handles 3042 from the same end of the two moving frames 3041 are arranged in an up-and-down crossing manner. The bottom surface of each moving frame 3041 at the front and rear ends is provided with a reference wheel 301 extending to the center, and the rolling surface of the reference wheel 301 is matched with the bottom surface of the carbon slide plate. As Figure 7 shown, a notch such as an L-shaped notch can be arranged at the top of each moving frame 3041 at the front and rear ends. The depths of the two notches are different, and a connecting handle 3042 extending to the center is arranged on each notch. The difference in the depth of the notches can be slightly greater than the thickness of the connecting handle 3042 to ensure that the two connecting handles 3042 can be arranged in a crossing manner.

[0025] Each connecting handle 3042 can be provided in an S-shaped structure, the non-free end of which is fixed on the corresponding notch, and the free end is provided with a button, facilitating subsequent hand pinching and clamping operation.

[0026] At the same time, as shown in Figure 6 In order to control the extension and retraction of the reference wheels and ensure smooth implementation of the clamping operation, a reverse U-shaped bracket 3043 is arranged on the periphery of each of the two moving frames 3041 at the front and rear ends, each reverse U-shaped bracket 3043 is connected with the corresponding moving frame 3041 through a respective spring mechanism, and each spring mechanism includes four spring assemblies of the same structure, which are arranged in two groups on both sides of the reverse U-shaped bracket 3043, specifically, each spring assembly includes a connecting shaft 3044 arranged between the reverse U-shaped bracket 3043 and the corresponding moving frame 3041, one end of the connecting shaft 3044 is fixed to the inner side of the reverse U-shaped bracket 3043, the other end penetrates through the corresponding moving frame 3041, and the end portion is provided with a stop ring 3045, which can be realized by a C-shaped buckle, and the stop ring 3045 is used to limit the movement position of the moving frame 3041 on the connecting shaft 3044. A linear bearing 3046 and a first buffer spring 3047 are coaxially sleeved on the connecting shaft 3044, wherein the first buffer spring 3047 is outside and the linear bearing 3046 is inside, the two ends of the first buffer spring 3047 abut against the reverse U-shaped bracket 3043 and the corresponding moving frame 3041 respectively, and the length of the linear bearing 3046 is less than that of the connecting shaft 3044, one end of the linear bearing 3046 is mounted on the corresponding moving frame 3041, for example, a bearing seat can be arranged at the corresponding position of the moving frame 3041 to mount the linear bearing 3045, so that the linear bearing 3046 can follow the movement of the moving frame 3041 and play a guiding role.

[0027] In this way, when the four connecting handles 3042 are pressed at the same time, the two moving frames 3041 are driven to move outward along the respective connecting shafts 3044 at the same time, at this time the first buffer spring 3047 in the spring mechanism is compressed to store energy, so as to drive the corresponding reference wheel 301 to retract, facilitating the placement of the detector on the carbon slide plate; while the four connecting handles 3042 are released at the same time, the first buffer spring 3047 in the spring mechanism is elongated and reset to release energy, thereby driving the two moving frames 3041 to move towards the center along the respective connecting shafts 3044 at the same time, to drive the corresponding reference wheel 301 to extend, so that the rolling surface cooperates with the bottom surface of the carbon slide plate, thereby realizing clamping of the carbon slide plate.

[0028] In order to facilitate the installation and fixation of the guide wheels 302, each of the moving frames 3041 is designed in an m-shaped structure, two door openings of which are used to accommodate the guide wheels 302, and a roller encoder 305 is arranged at the central clamping opening of one of the moving frames 3041, which is used to measure the moving distance of the detector along the carbon slide, and a reinforcing rib is arranged at the central clamping opening of the other moving frame 3041, so as to ensure the strength of the whole moving frame.

[0029] As shown in Figure 11 The adaptive adjusting mechanism comprises two groups of guide columns, each of which comprises two guide columns 306 arranged in parallel and at intervals, one group of the two guide columns 306 is arranged along the width direction of the carbon slide, and a second buffer spring 307 and an L-shaped sliding block 308 are sleeved on each of the guide columns 306 from top to bottom, the outer side of the free end of each L-shaped sliding block 308 is provided with a movable guide wheel 303, and the non-free end is sleeved on the corresponding guide column 306, in order to ensure that the movable guide wheel 303 is always in rolling contact with the carbon slide and avoid that the movable guide wheel 303 rotates around the guide column 306 during the movement of the detector, the two L-shaped sliding blocks 308 are symmetrically arranged, and a stop plate 309 is arranged between them, so that the L-shaped sliding block 308 is prevented from rotating circumferentially around the corresponding guide column by means of the stop plate 309, so that the movable guide wheel can always move along the length direction of the carbon slide and cannot be deflected; The other group of the two guide columns 306 is arranged along the length direction of the carbon slide, and a T-shaped sliding block 310 is sleeved on the two guide columns 306 at the same time, the vertical part of the T-shaped sliding block 310 is provided with a movable guide wheel 303, the two ends of the horizontal part of the T-shaped sliding block 310 are sleeved on the corresponding guide columns 306, and the guide column above the horizontal part is also sleeved with a second buffer spring 307; In this way, through the spring force test, the appropriate spring type is selected, and by means of the four second buffer springs 307, the contact pressure between the movable guide wheel 303 and the top surface of the carbon slide can be adaptively adjusted, the movable guide wheel 303 is always in contact with the carbon slide, and sufficient reaction force can be generated, that is, upward tension is provided for the whole detector, so that the reference wheel can always contact the bottom surface of the carbon slide, and accurate detection basis is provided for subsequent parameter measurement.

[0030] In order to strengthen the stability of the whole clamping mechanism, the two inverted U-shaped supports 3403 are connected by a plurality of reinforcing plates 311, such as two reinforcing plates on each side, each reinforcing plate 311 is connected with the side wall of the outer inverted U-shaped shell 312, a support seat for supporting and fixing the guide wheel 302 is arranged at the bottom of the outer inverted U-shaped shell 312, which can cooperate with the door opening of the corresponding moving frame, and the opening edge of the outer inverted U-shaped shell 312 corresponding to the inverted U-shaped support 3403 is connected by the inner inverted U-shaped reinforcing plate 313, so that the two inner inverted U-shaped reinforcing plates 313 can be connected with the outer inverted U-shaped shell 312 to form a whole, fixing the inverted U-shaped support 3403 and the moving frame 3041 in the inside, which can well improve the overall stability, and the second buffer spring 307 can be arranged between the L-shaped slider 308 and the outer inverted U-shaped shell 312, and the T-shaped slider 310 and the outer inverted U-shaped shell 312, the reverse force is transmitted to the moving frame 3041 through the outer inverted U-shaped shell 312 and then to the reference wheel 301, so that it can always adhere to the bottom surface of the carbon slide plate.

[0031] The detection unit 2 includes a processor connected with a distance measuring module, a main camera 203, an auxiliary camera 209 and a position detection module, and connected with a cloud server or a server of a remote control center through a communication module 205. The distance measuring module includes two laser distance measuring sensors arranged on both sides of the center line of the carbon slide plate, which are used to detect the distance information of the highest point and the lowest point of the current cross section of the effective detection area of the carbon slide plate. We can install the two laser distance measuring sensors side by side on the triangular support to form a laser distance measuring assembly 202, so that they are arranged on both sides of the center line of the carbon slide plate. The specific distance can be set according to the actual situation of the effective detection area of the carbon slide plate. Considering that the edge area of the carbon slide plate may have large-area appearance defects such as falling block and scratching, the position inward a certain distance (such as 5mm or other empirical value) from the edge is usually selected as the boundary of the effective detection area of the carbon slide plate, so as to define the highest point and the lowest point of the carbon slide plate wear, thereby determining the installation position of the two laser distance measuring sensors, avoiding physical defects of subsequent detection data; The position detection module is a roller encoder for measuring the position information of the detector on the carbon slide plate; In this way, we can set the sampling frequency of the main camera 203 and the laser ranging sensor to be the same, and the processor receives the distance information and position information of the highest point and the lowest point, calculates the remaining thickness of the current cross section according to the distance information of the lowest point of the current cross section, and calculates the angle of deviation of the current cross section according to the connection line of the highest point and the lowest point, and compares the remaining thickness and the angle of deviation with the corresponding threshold value, and outputs the abnormal position point, while controlling the main camera 203 to follow the shooting of the upper surface of the carbon slide plate corresponding to the current cross section, and the auxiliary camera 209 can be used to manually shoot the abnormal state points of any point on the outer surface of the carbon slide plate from multiple angles to generate a detection report, as shown in Figures 13-14 The detection report is uploaded to the cloud server or the server of the remote control center for subsequent verification, data tracing and maintenance guidance.

[0032] Specifically, as shown in Figure 8 、 9 , 12, we can set the detection unit 2 inside the square shell 201. In order to make full use of the internal space of the square shell 201, we arrange the laser ranging assembly 202, the camera 203 and the energy storage battery assembly 204 of the detection unit 2 along the center line of the carbon slide plate in sequence, and the control circuit board 209 and the communication module 205 and the positioning module 206 are arranged on both sides of the camera 203. The positioning module 206 can be used to provide the position information of the detection instrument, such as GNSS positioning module, to ensure that the sales product is consistent with the distribution right of the corresponding area, and to prevent different regional distributors from cross-regional stringing; the communication module 205 can be a 5G communication module and / or a 4G communication module and / or a WiFi module, and also includes corresponding antenna arrangement, charge and discharge control circuit, etc. In this way, the wear data in the detection instrument supports three data export methods at the same time: USB data export port and 5G and WiFi data wireless transmission module, which is more conducive to the data export of the staff. A touch screen 207 is arranged on the outer side of the control circuit board 209, and at this time the touch screen 207 is located on one side of the square shell 201. Of course, according to the actual needs, the touch screen 207 can also be arranged on the top surface of the square shell 201. At the same time, we also add an auxiliary camera 208, the lens of which is outwardly arranged and exposed on the surface of the square shell 201. At this time, the auxiliary camera 207 is equivalent to a mobile phone lens, and the detection instrument itself is equivalent to a mobile phone body. The staff can operate the touch screen of the detection instrument like operating a mobile phone to take pictures, and complete the multi-angle shooting of the abnormal points on the outer surface of the carbon slide plate, The laser ranging assembly 202 includes two laser ranging sensors arranged side by side, which are arranged on both sides of the center line of the carbon slide, and the specific distance can be set according to the actual situation of the carbon slide. In order to facilitate assembly, we use bolts to symmetrically install the two laser ranging sensors on the triangular support to form an integral structure, and then assemble it on the corresponding shell.

[0033] The energy storage battery assembly 204 is arranged near one side of the square shell 201, and a replacement button and an energy storage battery replacement interface can also be arranged on the side, which facilitates the replacement of the energy storage battery, and a wrist strap 4 for assisting in holding the square shell can also be arranged on the side opposite to the side. When the operator controls the touch screen, the wrist strap 4 can provide a certain auxiliary fixing force to prevent the operator from dropping the detector.

[0034] A handle 1 is arranged on the top surface of the square shell 201, and a clamping unit 3 is arranged on the bottom surface. One side surface is provided with a touch screen 206, but when the touch screen 206 is also arranged on the top surface of the square shell 201, the handle 1 needs to adopt a rotating structure to avoid interfering with the operation of the touch screen by the staff.

[0035] In addition, when the touch screen 206 is arranged on the side surface of the square shell 201, a power switch 5, a data transmission interface 6, a test port 7, and a cooling fan 9 are arranged on the top surface of the square shell 201. When formal detection is performed, it is convenient for the staff to operate, and when the touch screen is on the top surface of the square shell, the power switch 5, the data transmission interface 6, the test port 7, and the cooling fan 9 are transferred to the corresponding side surface.

[0036] Finally, a laser 8 is arranged at each of the front and rear ends of the top surface of the square shell 201 or the front and rear ends of the handle 1. The mounting structure of the laser 8 protrudes outward of the square shell 201 and is provided with a hole for emitting a laser beam. The cross laser lines emitted by the laser 8 can be used to indicate the starting position and the ending position of the detection of the carbon slide.
