Description

Technical Field

[0001] This utility model belongs to the technical field of rail transit inspection, specifically relating to a handheld intelligent carbon skateboard wear detector. Background Technology

[0002] With the booming development of urban rail systems, the demand for carbon sliding plates for pantographs in urban rail systems has also increased dramatically, and the service life of carbon sliding plates has received more attention. The pantograph-catenary system is a complex electromechanical dynamic system composed of the elastic suspension system of the power grid contact wire and the elastic system of the train pantograph, which are connected by the sliding of carbon sliding plates with the contact wire.

[0003] The pantograph makes sliding contact with the overhead contact line via a carbon sliding plate to collect current and transmit it to the train. During this process, the high-speed sliding contact between the carbon sliding plate and the overhead contact line often leads to continuous wear of the carbon sliding plate. If it is not replaced in time, it will pose a huge danger to the safety of track operation. Therefore, it is necessary to detect the wear of the carbon sliding plate during vehicle maintenance.

[0004] Currently, there are two main measurement methods on the market. One is manual measurement using tools such as vernier calipers, which is not only slow but also inaccurate, and subsequent data statistics are also quite troublesome. The other is automated measurement using intelligent detection devices, which requires the addition of a roller drive mechanism to move the detection equipment equipped with relevant detection devices along the carbon slide to complete the detection. This results in the detection equipment being too large and heavy, making it inconvenient to carry as an online periodic inspection device. Utility Model Content

[0005] This invention provides a handheld intelligent carbon skateboard wear detector, which solves the technical problems of low accuracy and slow measurement speed in existing manual measurement, while automated measurement devices are bulky, heavy, and inconvenient to carry.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A handheld intelligent carbon skateboard wear detector adopts a layered structure, comprising a handle, a detection unit, and a clamping unit from top to bottom. The detection unit is used to measure the parameters of the carbon skateboard. The clamping unit employs a wraparound structure to clamp the carbon slide plate, including multiple reference wheels located at the bottom of the carbon slide plate, multiple fixed guide wheels located on both sides of the carbon slide plate, and multiple movable guide wheels located on the top surface of the carbon slide plate. These reference wheels are connected to a scissor-type telescopic mechanism, and these movable guide wheels are connected to an adaptive adjustment mechanism. The scissor-type telescopic mechanism is used to control the extension and retraction of these reference wheels to achieve a wrap-around clamping of the carbon skateboard. The adaptive adjustment mechanism is used to ensure that the active guide wheels are always in contact with the top surface of the carbon skateboard, and that the reference wheels are always in contact with the bottom surface of the carbon skateboard.

[0007] Furthermore, the scissor-type telescopic mechanism includes two symmetrically arranged movable frames, and each movable frame has a connecting handle extending towards the center on the top surface at both ends of the front and rear ends, and the two connecting handles from the same end of the two movable frames are arranged vertically and horizontally. Each of the aforementioned mobile frames has reference wheels extending towards the center on the bottom surface at both the front and rear ends, and their rolling surfaces are in contact with the bottom surface of the carbon slide plate. An inverted U-shaped bracket is installed around the front and rear ends of each of the two movable frames. Each inverted U-shaped bracket is connected to the corresponding movable frame via its own spring mechanism. Pressing all four connecting handles at the same time will cause the two moving frames to move outwards simultaneously. At this time, the spring mechanism will be compressed, causing the corresponding reference wheel to retract. At the same time, the four connecting handles are released, the spring mechanism extends and resets, driving the two moving frames to move towards the center simultaneously, so that the corresponding reference wheels extend and their rolling surfaces mate with the bottom surface of the carbon skateboard.

[0008] Furthermore, each of the spring mechanisms includes four identical spring assemblies, arranged in pairs on both sides of the inverted U-shaped bracket. Each spring assembly includes a connecting shaft disposed between an inverted U-shaped bracket and a corresponding movable frame. One end of the connecting shaft is fixed to the inner side of the inverted U-shaped bracket, and the other end passes through the corresponding movable frame. A stop ring is provided at the end of the connecting shaft to limit the movement position of the movable frame on the connecting shaft. A linear bearing and a first buffer spring are coaxially mounted on the connecting shaft. The two ends of the first buffer spring abut against the inverted U-shaped bracket and the corresponding movable frame, respectively. The length of the linear bearing is less than the length of the connecting shaft, and one end of it is mounted on the movable frame.

[0009] Furthermore, each of the movable frames has a notch at the top of both its front and rear ends, with the two notches having different depths, and each notch has a connecting handle extending towards the center. Each of the connecting handles is configured with an S-shaped structure, and a button is provided at its free end.

[0010] Furthermore, each of the movable frames has an m-shaped structure, with two openings for accommodating fixed guide wheels. A roller encoder is installed at the central clamp of one of the moving frames. The roller encoder is used to calculate the distance the detector moves along the carbon slide plate.

[0011] Furthermore, the two inverted U-shaped brackets are connected by multiple reinforcing plates, each of which is connected to the side wall of the outer inverted U-shaped shell. A support base for supporting and fixing the guide wheel is provided at the bottom of the outer inverted U-shaped shell. The outer inverted U-shaped shell is connected to the opening edge of the corresponding inverted U-shaped bracket by an inner inverted U-shaped reinforcing plate. Furthermore, the adaptive adjustment mechanism includes two sets of guide posts, each set comprising two guide posts arranged in parallel at intervals. Each of the guide posts in one group is fitted with a second buffer spring and an L-shaped slider from top to bottom, and each L-shaped slider has a movable guide wheel on the outer side of its free end. The two L-shaped sliders are symmetrically arranged, with a stop plate in the middle, which is used to prevent the L-shaped sliders from rotating circumferentially around the corresponding guide post. The other set of two guide posts are simultaneously fitted with T-shaped sliders. The vertical part of the T-shaped slider is provided with a movable guide wheel, and the two ends of its horizontal part are respectively fitted onto the guide post. The guide post above the horizontal part is also fitted with a second buffer spring.

[0012] Furthermore, the two guide posts in one group are arranged along the width direction of the carbon slide plate, and the two guide posts in the other group are arranged along the length direction of the carbon slide plate.

[0013] Furthermore, the detection unit is housed inside the square housing and includes a laser ranging component, a main camera, and an energy storage battery component arranged sequentially along the center line of the carbon skateboard. A control circuit board, a communication module, and a positioning module are respectively located on either side of the main camera. A handle and a touch screen are provided on the top surface of the square housing, and a clamping unit is provided on the bottom surface. The handle is provided on the top surface of the square housing using a rotating structure. Alternatively, a handle may be provided on the top surface of the square housing, a touch screen may be provided on one of its sides, and a clamping unit may be provided on the bottom surface.

[0014] Furthermore, a laser is provided at each of the front and rear ends of the square housing. Their mounting structures protrude from the outside of the square housing and are reserved with holes for the laser beam to be emitted. The cross laser lines emitted by them are used to indicate the detection start position and detection end position of the carbon slide plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The detector is clamped onto the carbon skateboard using the clamping unit. Then, the person holds the handle and moves the detector along the carbon skateboard so that the detection unit can complete the parameter detection of the entire carbon skateboard. There is no need to add an additional roller drive mechanism, which can reduce the size and weight of the entire device to a certain extent, which helps to increase portability and practicality, and can meet the needs of online regular inspection of carbon skateboards.

[0016] 2. The scissor-type telescopic mechanism controls the retraction and extension of the reference wheel, facilitating the clamping of the detector onto the carbon slide plate. Simultaneously, the adaptive adjustment mechanism located on the top surface of the carbon slide plate, aided by the reaction force of the second buffer spring, ensures that the movable guide wheel remains in constant contact with the top surface of the carbon slide plate, providing guidance for the entire detector's operation. It also ensures that the reference wheel remains in constant contact with the bottom surface of the carbon slide plate, providing a stable data foundation for subsequent parameter testing.

[0017] 3. This utility model features a wrap-around clamping unit that uses the movable guide wheel on the top surface, the fixed guide wheel on the side, and the reference wheel on the bottom surface to wrap around the carbon slide plate, ensuring that the operator can smoothly move the testing instrument along the carbon slide plate, improving the user experience and making it easier to promote and apply.

[0018] 4. The detector of this utility model adopts a layered modular design concept. The top layer is the handle, the middle layer is the detection unit, and the bottom layer is the clamping unit, which is more conducive to disassembly, maintenance and functional expansion.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments, in conjunction with the accompanying drawings, provide a detailed description of the handheld carbon skateboard wear intelligent detector of this utility model. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0021] like Figure 1-2 As shown, this utility model provides a handheld intelligent carbon skateboard wear detector, which adopts a layered structure and includes a handle 1, a detection unit 2 and a clamping unit 3 from top to bottom. The detection unit 2 is used to measure the parameters of the carbon skateboard. The clamping unit 3 employs a wrap-around structure to clamp the carbon skateboard, including multiple reference wheels 301 located at the bottom of the carbon skateboard, multiple fixed guide wheels 302 located on both sides of the carbon skateboard, and multiple movable guide wheels 303 located on the top surface of the carbon skateboard. These reference wheels 301 are connected to a scissor-type telescopic mechanism 304, which controls the extension and retraction of these reference wheels 301 to achieve a wrap-around clamping of the carbon skateboard. These movable guide wheels 303 are connected to an adaptive adjustment mechanism, which ensures that these movable guide wheels 303 are always in contact with the top surface of the carbon skateboard, and that these reference wheels 302 are always in contact with the bottom surface of the carbon skateboard. In this way, the detector is clamped onto the carbon skateboard using the clamping unit 3, and then the handle is held to move the detector along the carbon skateboard, allowing the detection unit 2 to complete the parameter detection of the entire carbon skateboard. This eliminates the need for an additional roller drive mechanism, reducing the overall size and weight of the device, increasing portability, enhancing practicality, and meeting the needs of online periodic inspection of carbon skateboards.

[0022] Specifically as follows: like Figure 3-5 As shown in Figure 10, the entire testing instrument is divided into three layers: the upper handle 1, the middle testing unit 2, and the lower clamping unit 3. The clamping unit 3 has an inverted U-shaped structure, which forms a wrap-around clamping on the cross-section of the carbon slide plate. This facilitates clamping while ensuring the rolling coordination between the reference wheel 301, the guide wheel, and the carbon slide plate. This provides a guarantee for the staff to move the testing instrument smoothly along the carbon slide plate, which helps to improve the user experience.

[0023] To facilitate clamping, this utility model designs a scissor-type telescopic mechanism 304. The scissor-type telescopic mechanism 304 includes two symmetrically arranged movable frames 3041. Each movable frame 3041 has a connecting handle 3042 extending towards the center on the top surface at both ends. The two connecting handles 3042 from the same end of the two movable frames 3041 are arranged vertically and horizontally. Each movable frame 3041 has a reference wheel 301 extending towards the center on the bottom surface at both ends. The rolling surface of the wheel 301 is in contact with the bottom surface of the carbon slide plate. like Figure 7 As shown, we can provide notches, such as L-shaped notches, at the top of both ends of each mobile frame 3041. The depths of these two notches are different, and each notch is provided with a connecting handle 3042 extending towards the center. 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 set crosswise.

[0024] Each connecting handle 3042 can be configured as an S-shaped structure, with its non-free end fixed to the corresponding notch, and its free end equipped with a button for easy subsequent hand gripping operation.

[0025] At the same time, such as Figure 6 As shown, in order to control the extension and retraction of the reference wheel and ensure the smooth implementation of the clamping operation, we simultaneously cover the outer periphery of the front and rear ends of the two movable frames 3041 with an inverted U-shaped bracket 3043. Each inverted U-shaped bracket 3043 is connected to the corresponding movable frame 3041 through its own spring mechanism. Each spring mechanism includes four spring assemblies with the same structure. They are arranged in pairs on both sides of the inverted U-shaped bracket 3043. Specifically, each spring assembly includes a connecting shaft 3044 disposed between the inverted U-shaped bracket 3043 and the corresponding movable frame 3041. One end of the connecting shaft 3044 is fixed to the inner side of the inverted U-shaped bracket 3043, and the other end passes through the corresponding movable frame 3041. A stop ring 3045 is provided at its end. The stop ring 3045 can be realized by a C-shaped buckle. The stop ring 3045 is used to limit the movement position of the movable frame 3041 on the connecting shaft 3044. A linear bearing 3046 and a first buffer spring 3047 are coaxially mounted on the connecting shaft 3044, with the first buffer spring 3047 on the outside and the linear bearing 3046 on the inside. The two ends of the first buffer spring 3047 abut against the inverted U-shaped bracket 3403 and the corresponding movable frame 3041, respectively. The length of the linear bearing 3046 is less than the length of the connecting shaft 3044, and one end of it is mounted on the corresponding movable frame 3041. A bearing seat can be provided at the corresponding position of the movable frame 3041 to install the linear bearing 3045, so that the linear bearing 3046 can follow the movement of the movable frame 3041 and play a guiding role.

[0026] Thus, when all four connecting handles 3042 are pressed simultaneously, the two moving frames 3041 move outward along their respective connecting shafts 3044. At this time, the first buffer spring 3047 in the spring mechanism is compressed and stores energy, which drives the corresponding reference wheel 301 to retract, making it easier to place the detector on the carbon slide plate. When all four connecting handles 3042 are released simultaneously, the first buffer spring 3047 in the spring mechanism extends and resets, releasing energy, which drives the two moving frames 3041 to move towards the center along their respective connecting shafts 3044, which drives the corresponding reference wheel 301 to extend, so that its rolling surface mates with the bottom surface of the carbon slide plate, thereby achieving the clamping of the carbon slide plate.

[0027] To facilitate the installation of the fixed guide wheel 302, each movable frame 3041 is designed with an M-shaped structure, with two openings for accommodating the fixed guide wheel 302. A roller encoder 305 is installed at the central clamp of one of the movable frames 3041 to measure the distance the detector moves along the carbon slide plate. A reinforcing rib is installed at the central clamp of the other movable frame 3041 to ensure the strength of the entire movable frame.

[0028] like Figure 11 As shown, the adaptive adjustment mechanism includes two sets of guide columns. Each set of guide columns includes two guide columns 306 arranged in parallel and spaced apart. The two guide columns 306 in one set are arranged along the width direction of the carbon slide plate. Each guide column 306 is fitted with a second buffer spring 307 and an L-shaped slider 308 from top to bottom. The free end of each L-shaped slider 308 is provided with a movable guide wheel 303, and its non-free end is fitted on the corresponding guide column 306. In order to ensure that the movable guide wheel 303 always rolls in contact with the carbon slide plate and to prevent the movable guide wheel 303 from rotating around the guide column 306 during the movement of the detector, the two L-shaped sliders 308 are arranged symmetrically, and a stop plate 309 is provided in the middle. In this way, the stop plate 309 can prevent the L-shaped slider 308 from rotating around the corresponding guide column in the circumferential direction, so that the movable guide wheel can always move along the length direction of the carbon slide plate without deflection. The other set of two guide posts 306 are arranged along the length of the carbon slide plate. A T-shaped slider 310 is also mounted on the two guide posts 306. The vertical part of the T-shaped slider 310 is provided with a movable guide wheel 303, and the two ends of its horizontal part are respectively mounted on the guide posts 306. A second buffer spring 307 is also mounted on the guide post above the horizontal part. By testing the force of the springs and selecting the appropriate spring type, the four second buffer springs 307 can not only adaptively adjust the contact pressure between the movable guide wheel 303 and the top surface of the carbon slide plate, ensuring that the movable guide wheel 303 is always in contact with the carbon slide plate, but also generate sufficient reaction force, that is, provide an upward pull for the entire testing instrument, thereby ensuring that the reference wheel can always contact the bottom surface of the carbon slide plate, providing an accurate testing basis for subsequent parameter measurements.

[0029] To enhance the stability of the entire clamping mechanism, the two inverted U-shaped brackets 3403 are connected by multiple reinforcing plates 311, such as one reinforcing plate on each side. Each reinforcing plate 311 is connected to the side wall of the outer inverted U-shaped housing 312. A support seat for supporting and fixing the guide wheel 302 is provided at the bottom of the outer inverted U-shaped housing 312. This support seat can cooperate with the door opening of the corresponding movable frame, and the outer inverted U-shaped housing 312 is connected to the opening edge of the corresponding inverted U-shaped bracket 3403 by an inner inverted U-shaped reinforcing plate 313. In this way, the two inner inverted U-shaped brackets 3403 are connected to each other. The U-shaped reinforcing plate 313 can be connected to the outer inverted U-shaped shell 312 to form a whole, fixing the internal inverted U-shaped bracket 3403 and the moving frame 3041 together, which can greatly improve the overall stability. At the same time, the second buffer spring 307 can be set 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. Its reverse force is transmitted through the outer inverted U-shaped shell 312 to the moving frame 3041 and then to the reference wheel 301, so that it can always be in close contact with the bottom surface of the carbon slide plate.

[0030] like Figure 8 , 9 As shown in Figure 12, the detection unit 2 is located inside the square housing 201. To fully utilize the internal space of the square housing 201, the laser ranging component 202, camera 203, and energy storage battery component 204 of the detection unit 2 are arranged sequentially along the center line of the carbon skateboard. A control circuit board 209, a communication module 205, and a positioning module 206 are respectively located on both sides of the camera 203. The positioning module 206 can provide the location information of the detector, such as a GNSS positioning module, to ensure that the products sold are consistent with the corresponding regional distribution rights and to prevent cross-regional sales by distributors from different areas. 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 settings, charging and discharging control circuits, etc. In this way, the wear data in the detector supports three data export methods simultaneously: USB data export port, 5G and WiFi wireless data transmission modules, which is more convenient for staff to export data.

[0031] A touchscreen 207 is mounted on the outer side of the control circuit board 209, located on one side of the square housing 201. Alternatively, it can be mounted on the top surface of the housing 201, depending on the specific requirements. An auxiliary camera 208 is also included, with its lens facing outwards and exposed on the surface of the square housing 201. In this configuration, the auxiliary camera 207 functions similarly to a mobile phone camera lens, while the detector itself acts like a mobile phone. Operators can use the detector's touchscreen to take multi-angle photos of any abnormal points on the carbon skateboard, much like taking photos with a mobile phone. The laser ranging assembly 202 includes two laser ranging sensors arranged side by side, which are positioned on both sides of the center line of the carbon skateboard. The specific distance setting can be determined according to the actual situation of the carbon skateboard. For ease of assembly, the two laser ranging sensors are symmetrically mounted on the triangular bracket with bolts to form an integral structure, and then assembled onto the corresponding housing.

[0032] The energy storage battery assembly 204 is located on one side of the square housing 201. A replacement button and an energy storage battery replacement interface can be provided on this side to facilitate the replacement of the energy storage battery. A wrist strap 4 for assisting in holding the square housing can also be provided on the opposite side. When the operator operates the touch screen, the wrist strap 4 can provide a certain auxiliary fixing force to prevent the operator from dropping the device and causing damage to the detector.

[0033] A handle 1 is provided on the top surface of the square housing 201, and a clamping unit 3 is provided on the bottom surface. A touch screen 206 is provided on one side. However, when the touch screen 206 is also provided on the top surface of the square housing 201, the handle 1 needs to adopt a rotating structure to avoid interfering with the operator's operation of the touch screen.

[0034] In addition, when the touch screen 206 is located on the side of the square housing 201, a power switch 5, a data transmission interface 6, a test port 7, and a cooling fan 9 are also provided on the top surface of the square housing 201. This facilitates operation by staff during formal wear testing. When the touch screen is on the top surface of the square housing, these power switches 5, data transmission interface 6, test port 7, and cooling fan 9 are moved to the corresponding side.

[0035] Finally, a laser 8 is installed at the front and rear ends of the top surface of the square housing 201 or at the front and rear ends of the handle 1. Their mounting structure protrudes from the outside of the square housing 201 and has reserved holes for the laser beam to be emitted. The cross laser lines emitted by them can be used to indicate the detection start position and detection end position of the carbon slide plate.

[0036] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples. Various changes or modifications can be made to these embodiments without departing from the principles and essence of the present invention. Therefore, the scope of protection of the present invention is defined by the appended claims.

[0037] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
