[0004] However, the traditional calibration methods mentioned above have problems such as being complicated to operate, time-consuming and labor-intensive, and having poor calibration accuracy and precision. Utility Model Content

[0014] In one embodiment, the axis of the wire hole is arranged perpendicular to the length direction of the groove.

[0015] In one embodiment, the groove is a dovetail groove structure, and the bottom of the moving block is a dovetail-shaped protrusion.

[0016] In one embodiment, the end of the lateral support is provided with a vertically arranged sleeve, which is slidably connected to the rod-shaped structure.

[0031] In railway power supply, the calibration process of pantograph-catenary testing equipment is a crucial step in ensuring the accuracy of pantograph-catenary testing. Traditional calibration methods suffer from problems such as complex operation, time-consuming and labor-intensive processes, and poor calibration precision and accuracy.

[0032] See Figure 1 , Figure 1 A schematic diagram of the structure of a calibration device for a pantograph-catenary testing equipment according to an embodiment of this application is shown.

[0033] To address the aforementioned technical problems, one embodiment of this application provides a calibration device for pantograph-catenary inspection equipment, comprising a support member 10, a lateral sliding member 20, and a rangefinder 30, to achieve accurate calibration of the pantograph-catenary inspection equipment.

[0034] In this embodiment, the support member 10 includes a base 11, a vertical support portion 12, and a horizontal support portion 13. The base 11 is used to install on the roof of the locomotive, the vertical support portion 12 is vertically disposed on the base 11, and the horizontal support portion 13 is movably connected to the vertical support portion 12. A horizontal sliding member 20 is movably disposed on the horizontal support portion 13; the horizontal sliding member 20 is configured to be fixed to the contact line above the locomotive. A rangefinder 30 is mounted on the horizontal support portion 13, and the rangefinder 30 is configured to measure the distance from the horizontal support portion 13 to the roof of the locomotive.

[0035] The base 11 is made of metal and is fixedly installed on the roof of the locomotive to maintain the stability of the calibration device and avoid measurement errors.

[0036] The vertical support 12 is a rod-shaped structure. The vertical support 12 is vertically mounted on the base 11 and is made of metal.

[0037] The transverse support 13 is a rod-shaped or plate-shaped structure. The transverse support 13 is connected to the vertical support 12 via a movable connector, allowing the transverse support 13 to move vertically to adjust the vertical distance of the transverse sliding member 20 provided on the transverse support 13, adapting to different calibration requirements.

[0038] The lateral sliding member 20 is movably mounted on the lateral support 13 and is slidably connected to the lateral support 13. The lateral sliding member 20 is used to fix the contact wire above the locomotive. The lateral sliding member 20 slides along the length of the lateral support 13 to adjust the lateral distance of the contact wire, that is, the distance of the contact wire from the center of the pantograph. The lateral sliding member 20 moves with the lateral support 13 to adjust the vertical distance of the contact wire.

[0039] The rangefinder 30 is a laser rangefinder, which is mounted on the transverse support 13. The rangefinder 30 is used to measure the distance from the transverse support 13 to the roof of the locomotive, that is, the distance from the contact line fixed on the transverse support 13 to the roof of the locomotive, so as to assist the vertical movement of the transverse support 13 and adjust the vertical distance of the contact line.

[0040] In the specific implementation process, the lateral distance of the contact line is adjusted by moving the lateral sliding member 20 to achieve the set lateral calibration distance. The lateral support 13 is moved, and the distance from the contact line on the lateral support 13 to the roof of the locomotive is measured using a rangefinder 30. The vertical distance of the contact line is then adjusted to achieve the set vertical calibration distance. A pantograph-catenary detector is used to detect the lateral and vertical distances of the contact line. The distance data measured by the pantograph-catenary detector is compared with the distance data set by the calibration device. By calculating the error between the two, it is determined whether the measurement accuracy of the pantograph-catenary detector meets the requirements. If the error value is within the allowable error range, the measurement accuracy of the pantograph-catenary detector meets the standard. If the error value exceeds the allowable error range, the pantograph-catenary detector needs to be calibrated.

[0041] As shown above, compared with the traditional calibration method, by moving the lateral sliding member 20 and the lateral support 13, the lateral and vertical set distances of the contact line are adjusted, and the distance of the contact line is detected by the pantograph-catenary detector. The calibration accuracy of the pantograph-catenary detector is judged by comparing the detected distance with the set distance, which simplifies the calibration process and improves work efficiency.

[0042] Combination Figure 1 As shown, Figure 1 A schematic diagram of the structure of a calibration device for a pantograph-catenary testing equipment according to an embodiment of this application is shown.

[0043] In some embodiments, the lateral support 13 is provided with a scale 21.

[0044] Specifically, the scale 21 is horizontally disposed on one side surface of the transverse support 13, maintaining a horizontal position with the transverse support 13. The zero point of the scale 21 is located at the center point of the transverse support 13, meaning the scale 21 has a two-way range on the transverse support 13. The single-way range of the scale 21 is 0-750mm, meaning the total range of the scale 21 is 0-1500mm, with an accuracy of ±1mm. The transverse slider 20 is used for the contact line; the transverse slider 20 moves on the transverse support 13 to adjust the transverse distance of the contact line as needed.

[0045] The total range of scale 21 can also be 1300mm, 1400mm, 1500mm, 1600mm, 1700mm, 1800mm, etc. The range of scale 21 can be adjusted according to specific usage requirements, which will not be elaborated here.

[0046] The length of the transverse support 13 can be adjusted according to specific usage requirements. The transverse support 13 can be shortened or lengthened, which will not be elaborated here.

[0047] In one embodiment, the vertical support 12 includes two parallel, spaced-apart rod-shaped structures, the bottom ends of which are detachably connected to the base 11.

[0048] Specifically, the vertical support 12 consists of two parallel, spaced-apart rod-like structures. The bottom end of the rod-like structure is detachably connected to the base 11. For example, if the bottom end of the rod-like structure has threads on its outer periphery, the base 11 will have a corresponding threaded interface. Alternatively, the bottom end of the rod-like structure can be fixed to the base 11 by bolts or the like, facilitating subsequent disassembly and installation.

[0049] In one embodiment, the transverse support 13 is further provided with a sliding groove 22. The transverse sliding member 20 includes a moving block 23, which is slidably connected to the sliding groove 22, and the moving block 23 is provided with a through wire hole 24.

[0050] Specifically, the slide 22 is located at the top of the transverse support 13 and extends along the length of the transverse support 13. The location of the slide 22 can be adjusted according to specific needs, and will not be elaborated here.

[0051] The movable block 23 has a cuboid structure. It is movably mounted within the slide groove 22, slidably connected to it, and can move along the length of the slide groove 22. A through-hole 24 is provided within the movable block 23 for installing and fixing the contact wire. The contact wire passes through the hole 24 to simulate the position of the contact wire on the pantograph. The lateral distance of the movable block 23 within the slide groove 22 is adjusted to change the lateral setting distance.

[0052] In one embodiment, the wire hole 24 is located in the central region of the moving block 23, and the axis of the wire hole 24 is perpendicular to the length direction of the slide groove 22.

[0053] Specifically, the central area of ​​the moving block 23 has a through-hole 24, the diameter of which matches the diameter of the contact wire. The axis of the through-hole 24 is perpendicular to the length of the slide 22 and is used to allow the contact wire to pass through, simulating contact between the contact wire and the pantograph to improve calibration accuracy. The through-hole 24 can also be located in other areas of the moving block 23, depending on specific usage requirements, which will not be elaborated here.

[0054] In one embodiment, the slide 22 is a dovetail groove structure, and the bottom of the moving block 23 is a dovetail-shaped protrusion.

[0055] Specifically, the slide 22 adopts a dovetail groove structure, and the moving block 23 is slidably connected to the slide 22. Its bottom end is a dovetail-shaped protrusion, which is adapted to the dovetail groove structure of the slide 22. The dovetail groove structure has guiding and stability properties, which can effectively prevent the moving block 23 from shifting during the sliding process.

[0056] In one embodiment, the end of the transverse support 13 is provided with a vertically arranged sleeve 25, which is slidably connected to the rod-shaped structure.

[0057] Specifically, the horizontal support 13 is a cuboid structure made of aluminum alloy. Vertically positioned sleeves 25 are provided at both ends of the horizontal support 13. These sleeves 25 are fitted onto the vertical support 12 and slidably connected to the rod-shaped vertical support 12, enabling vertical movement of the horizontal support 13.

[0058] The sleeve 25 is also equipped with a locking bolt. By tightening the locking bolt, the horizontal support 13 is fixed on the vertical support 12, thereby realizing the vertical height adjustment of the horizontal support 13.

[0059] Combination Figure 1 As shown, Figure 1 A schematic diagram of the structure of a calibration device for a pantograph-catenary testing equipment according to an embodiment of this application is shown.

[0060] In some embodiments, the rangefinder 30 is a laser rangefinder, and the laser emission direction of the laser rangefinder is arranged parallel to the axis of the vertical support 12.

[0061] Specifically, the laser rangefinder is embedded in the bottom surface of the transverse support 13. The laser emission direction of the laser rangefinder is parallel to the axis of the vertical support 12, and its measurement accuracy is ±1mm. The laser rangefinder reads the vertical height of the transverse support 13 in real time, i.e., the vertical distance from the contact line to the roof of the locomotive, which facilitates the setting of the vertical distance and improves work efficiency and calibration accuracy. The laser rangefinder can also be installed on one side of the transverse support 13, as long as the laser emission direction of the laser rangefinder faces the roof of the locomotive. The installation position of the laser rangefinder can be adjusted adaptively according to specific usage requirements, which will not be elaborated here.

[0062] In one embodiment, a level 40 is also provided on the lateral support 13.

[0063] Specifically, a circular level 40 is provided on the transverse support 13. The level 40 contains liquid and air bubbles. By observing the position of the air bubbles, the operator can visually determine whether the transverse support 13 is in a horizontal state.

[0064] If the bubble is not in the center, the horizontal support 13 can be adjusted to make the horizontal support 13 horizontal, thereby ensuring the accuracy of the calibration.

[0065] The level 40 is installed at the top or one side of the horizontal support 13. As long as the horizontal support 13 is kept horizontal, the installation position of the level 40 can be adjusted according to specific usage requirements, which will not be elaborated here.

[0066] In one embodiment, the base 11 is a tripod, and the bottom end of the rod-shaped structure is connected to the tripod via a threaded interface.

[0067] Specifically, the base 11 adopts a tripod structure, with its three legs made of aluminum alloy. A circular connector is located at the top of the tripod, with internal threads on its inner wall. The bottom of the rod-shaped structure has an external thread interface that matches the internal threads of the connector. By rotating the rod-shaped structure, it can be installed on the tripod, and installation and disassembly are simple. All three legs of the tripod have anti-slip rubber pads on their bottoms to improve installation stability.

[0068] The base 11 adopts a wheel structure, and the vertical support part 12 with a rod-like structure is connected to the base 11 and fixed to the roof of the locomotive. Alternatively, the bottom end of the base 11 is provided with a support plate, which is fixed to the roof of the locomotive to fix the vertical support part 12. The structure of the base 11 can be adapted to specific usage requirements, and will not be described in detail here.

[0069] In the specific implementation process, the contact wire is passed through the wire hole 24 of the moving block 23, and a wire clamp is used to fix the contact wire to the moving block 23 to ensure that the contact wire will not loosen during movement. The moving block 23 is manually pushed to slide along the slide groove 22. During the sliding process, the scale 21 on one side of the transverse support 13 is observed, and the contact wire is adjusted to the preset transverse distance position according to the calibration requirements.

[0070] Activate the laser rangefinder to measure the vertical distance between the contact line and the roof. Based on the measurement results, adjust the height of the transverse support 13 to bring the contact line to the preset vertical calibration height.

[0071] The pantograph-catenary line detection device is activated to detect the lateral and vertical distances of the contact line. The device transmits the detected distance data to the data processing equipment in real time. The distance data measured by the pantograph-catenary line detection device is compared with the distance data preset by the calibration device. By calculating the error value between the two, it is determined whether the accuracy of the pantograph-catenary line detection device meets the requirements.

[0072] The above-mentioned calibration device is simple to operate and has high calibration efficiency. It effectively solves the problems existing in traditional calibration methods, provides a guarantee for the accurate calibration of pantograph-catenary testing equipment, and helps to improve the safety and reliability of railway power supply systems.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
