Description

Technical Field

[0001] This utility model relates to the field of scientific and technological analysis technology, and in particular to a carbon slide plate fixing experimental device. Background Technology

[0002] Carbon contact plates are a key component of pantographs in electrified railways. Their performance directly determines the current collection quality and overall service life of the pantograph, which is crucial for ensuring the stable operation of the railway power supply system. In actual operation, the carbon contact plate needs to be in continuous contact with the contact wire to achieve current transmission. Therefore, its wear condition is an important indicator for evaluating the reliability of the pantograph, and relevant wear test data also serve as a key basis for the selection of carbon contact plate materials and the optimization of pantograph structure.

[0003] Traditional testing methods often employ single-point contact or simple mechanical clamps to fix the carbon contactor, which cannot fully simulate the complex contact environment between the pantograph and the contact wire in actual operation, nor can they accurately reproduce the different contact angles between the two, resulting in significant deviations between experimental results and actual operating conditions. Furthermore, traditional methods lack precise force control and data monitoring capabilities, making it impossible to obtain key parameters such as contact force in real time, further reducing the reliability and repeatability of experimental data and hindering effective support for research on the wear mechanism of the carbon contactor and the optimized design of the pantograph system. Therefore, we provide a carbon contactor fixing experimental device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a carbon strip fixing experimental device. This device solves the technical problems of traditional carbon strip fixing experimental devices, such as the inability to simulate multi-angle contact between the pantograph and the contact wire leading to data deviation, difficulty in accurately controlling the contact force, the need to adjust the structure when replacing the carbon strip, and poor versatility. It achieves the ability to simulate the real contact state between the pantograph and the contact wire, accurately monitor experimental data, support horizontal and vertical position adjustment, adapt to different carbon strips, and is easy to operate. It provides reliable support for carbon strip wear research, material selection, and pantograph optimization.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a carbon slide plate fixing experimental device, including a base that is slidably connected to a fixing seat.

[0006] The fixed base has a lead screw 1 rotatably mounted on its side end and threadedly connected to the base. Two sets of round rods slidably connected to the base are mounted inside the fixed base. A concave block is slidably connected in the middle groove at the top of the base. A lead screw 2 is threadedly connected to the concave block. Two sets of fixed long blocks are mounted on the top of the base near the fixed base end. A filling chamber seat is mounted on one end of each fixed long block. Two sets of fixing screws are threadedly mounted on the top of the filling chamber seat. Slide rails are mounted on both sides of the top of the base. Fixing components are slidably connected to the slide rails and connected to the other end of the fixed long blocks. A buffer spring is connected between the fixing component and the fixed long block at the end away from the concave block. A sensor is provided at the top of the fixing component that contacts the two sides of the lead screw to achieve multi-directional fixed position adjustment.

[0007] Preferably, the bottom end of the fixing seat is on the same horizontal plane as the bottom end of the base, and fixing holes are provided on both sides of the top end of the fixing seat to fix it to the test bench.

[0008] Preferably, the round rods are symmetrically distributed on both sides of the lead screw, and the two sets of fixing screws fix one end of the carbon slide plate inside the filling cavity seat.

[0009] Preferably, the fixing member is slidably connected to the inside of the fixed long block via a long rod, the buffer spring has a pre-compression of 5-10 mm in its natural state, and the buffer spring is made of 60Si2Mn spring steel.

[0010] Preferably, both lead screw one and lead screw two are equipped with rotating handles at their outer ends, and the outer surface of the slide rail is coated with a polytetrafluoroethylene wear-resistant coating.

[0011] Preferably, when one side of the sensor is in close contact with the other end of the carbon slide plate, the other end of the lead screw is pressed against the sensor.

[0012] By employing the above technical solution, this utility model provides a carbon slide plate fixing experimental device, which has at least the following beneficial effects: 1.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] To address the problems of traditional carbon strip fixing experimental devices, such as inability to simulate multi-angle contact between the pantograph and contact wire leading to data deviations, difficulty in accurately controlling contact force, and the need for structural adjustments and poor versatility when replacing carbon strips, this embodiment provides a carbon strip fixing experimental device. This device can simulate the actual contact state between the pantograph and contact wire, accurately monitor experimental data, support horizontal and vertical position adjustment, adapt to different carbon strips, and is easy to operate. It provides reliable support for carbon strip wear research, material selection, and pantograph optimization. Please refer to... Figure 1 - Figure 6The carbon slide plate fixing experimental device includes a base 2 slidably connected to a fixing seat 1. The bottom end of the fixing seat 1 and the bottom end of the base 2 are on the same horizontal plane, providing a stable and flat reference support surface for the entire device. This avoids tilting of the device due to the inconsistency in height between the two, ensuring that the base 2 slides smoothly on the fixing seat 1 when its lateral position is adjusted by the lead screw 3. At the same time, it ensures that the initial posture of the carbon slide plate after fixing meets the experimental reference requirements, laying a flat structural foundation for simulating the actual contact state between the pantograph and the contact wire, reducing experimental position deviations caused by uneven reference surfaces. In addition, fixing holes are opened on both sides of the top of the fixing seat 1 to fix it to the test platform. The fixing seat 1 is fixed to the test platform by bolts, thereby limiting the displacement or shaking of the fixing seat 1 during the experiment, which improves the stability of the experiment to a certain extent.

[0019] Traditional carbon contact line testing often employs single-point contact or simple mechanical clamping methods, which fail to fully simulate the complex contact environment of the pantograph and contact wire during actual operation, and cannot accurately reproduce the contact states at different angles, resulting in significant deviations between experimental results and real-world conditions. Furthermore, traditional methods lack precise force control mechanisms and real-time data monitoring, making it impossible to dynamically acquire key parameters such as contact force, further weakening the reliability and repeatability of experimental data. To address these issues...

[0020] A lead screw 3, threadedly connected to the base 2, is rotatably mounted on the side end of the fixed base 1. Two sets of round rods 4, slidably connected to the base 2, are mounted inside the fixed base 1. A concave block 5 is slidably connected to the central groove at the top of the base 2. A lead screw 6 is threadedly connected to the concave block 5. Both lead screws 3 and 6 have rotating handles at their outer ends, thus improving ease of operation and adjustment accuracy. Two sets of fixed long blocks 7 are mounted on the top of the base 2 near the fixed base 1. A filling chamber seat 8 is mounted at one end of each fixed long block 7. Two sets of fixing screws 9 are threadedly mounted on the top of the filling chamber seat 8. Slide rails 10 are mounted on both sides of the top of the base 2. The outer surface of the slide rail 10 is coated with a polytetrafluoroethylene wear-resistant coating to reduce frictional loss between the fixing component 11 and the slide rail 10 during sliding, preventing a decrease in accuracy of the slide rail 10 due to wear after long-term use. Simultaneously, the low friction characteristic allows the fixing component 11 to slide more smoothly, preventing misalignment of the contact position between the sensor 13 and the carbon slide plate due to jamming, ensuring the moving accuracy of the fixing component 11, and providing a reliable guarantee for the stable contact of the sensor 13 with the carbon slide plate and accurate transmission of contact force data. This adapts to the usage requirements of multiple experiments of the device. A fixing component 11 is slidably connected to the slide rail 10 and connected to the other end of the fixed long block 7. The fixing component 11... The excessively long rod is internally slidably connected to the fixed long block 7, providing additional precise guidance for the movement of the fixing component 11. This, together with the slide rails 10 on both sides of the top of the base 2, forms a double guiding structure, preventing the fixing component 11 from shifting or tilting when subjected to the tightening force of the lead screw 6 or the force of the buffer spring 12. A buffer spring 12 connects the end of the fixing component 11 away from the concave block 5 and the fixed long block 7. The buffer spring 12 has a pre-compression of 5-10 mm in its natural state, and is made of 60Si2Mn spring steel, giving it excellent elastic limit and fatigue resistance. It can ensure that the spring maintains stable elasticity after long-term repeated force (such as adjusting the position of the fixing part 11 multiple times) and is not prone to permanent deformation. The top of the fixing part 11 is equipped with a sensor 13 that contacts the side of the lead screw 6 to realize multi-directional fixed position adjustment. When one side of the sensor 13 is in close contact with the other end of the carbon slide plate, the other end of the lead screw 6 presses against the sensor 13 to realize bidirectional stable fixation of the carbon slide plate. This prevents the carbon slide plate from loosening or shifting due to simulated contact force and buffer spring 12 during the experiment, ensuring that the carbon slide plate is always in the preset experimental position, and the sensor 13 can be easily replaced according to experimental needs.

[0021] First, fix the fixed base 1 to the test bench through the fixing holes on both sides of its top. Rotate the screw 3 by turning the handle. Since the screw 3 is threadedly connected to the base 2 and the round rods 4 are symmetrically distributed on both sides of the screw 3 to assist the base 2 in sliding, the base 2 can be driven to adjust its lateral position on the fixed base 1. This allows the inner side of the fixed base 1 to limit the bending end of the carbon slide plate, which helps to improve the accuracy of the carbon slide plate test data. One end of the carbon slide plate is placed into the filling chamber seat 8 and fixed with two sets of fixing screws 9. The other end of the carbon slide plate is placed between the fixing part 11 and the sensor 13, and the side of the other end is attached to the sensor 13, so that the relevant data can be obtained more accurately. Since the concave block 5 slides in the groove in the middle of the top of the base 2, by rotating the handle at the outer end of the lead screw 6, the lead screw 6 is pressed against the sensor 13. The sensor 13 can provide real-time feedback on the contact force, providing accurate data for subsequent analysis and preventing interference from external environmental factors. The buffer spring 12 provides buffering force. Finally, through the cooperation of various structures, the carbon slide plate is fixed in multiple directions and its position is adjusted. At the same time, the sensor 13 transmits accurate data to simulate the real contact state between the pantograph and the contact wire to complete the experiment.
