Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit maintenance equipment technology, specifically a quick-release carbon sliding plate for pantographs in maintenance equipment. Background Technology
[0002] The pantograph is a key component for rail transit vehicles to obtain electrical energy from the overhead contact line. As the part that directly contacts the pantograph with the overhead contact line, the carbon sliding plate will wear down due to friction during long-term operation. It needs to be inspected and replaced regularly to ensure the normal power supply and safe operation of the vehicle.
[0003] Currently, traditional pantograph carbon contact plates are typically fixed to the pantograph head with multiple bolts. When replacing the carbon contact plate during maintenance operations, operators need to use wrenches and other tools to remove the bolts one by one, replace the new carbon contact plate, and then tighten the bolts one by one. The entire disassembly and assembly process is cumbersome and time-consuming. Especially when emergency repairs or batch maintenance of multiple vehicles are required, the traditional method of disassembling and assembling carbon contact plates will seriously affect the efficiency of maintenance operations, which may result in vehicles not being able to be put into operation in a timely manner, causing operational scheduling pressure. In addition, the bolts are prone to loosening or corrosion under long-term vibration, which further increases the difficulty of disassembly and may even cause delays in carbon contact plate replacement due to bolt damage. Therefore, those skilled in the art provide a quick-release carbon contact plate for pantograph maintenance to solve the problems mentioned in the background art. Utility Model Content

[0022] Please see Figures 1-5 In this embodiment of the utility model, a quick-release carbon sliding plate for a maintenance pantograph includes a base 1 and a pantograph body 10. A carbon sliding plate body 2 is fixedly connected to the inner bottom wall of the base 1. A set of fixing grooves 3 are provided on both the front and back of the carbon sliding plate body 2. A set of fixing cylinders 4 are fixedly connected to both the front and back of the base 1. Fixing plates 5 are fixedly connected to the sides of the two sets of fixing cylinders 4 that are far apart from each other. Through holes 24 are provided inside the two sets of fixing plates 5. Springs 6 are fixedly connected to the sides of the two sets of fixing plates 5 that are close to each other. Fixing blocks 7 are fixedly connected to the ends of the two sets of springs 6 that are close to each other. Each of the two sets of fixed blocks 7 has a fixed post 8 fixedly connected to its opposite side. Each of the two sets of fixed posts 8 has a handle 9 fixedly connected to its opposite side. Pulling the handle 9 causes the fixed post 8 and the fixed block 7 to compress the spring 6 and disengage from the fixing groove 3 of the carbon slide body 2. This allows for quick disassembly without tools, greatly improving maintenance efficiency. The spring 6 can push the fixed block 7 to be tightly inserted into the fixing groove 3. Together with the base 1, the carbon slide body 2 is supported, ensuring that the carbon slide body 2 does not loosen during operation and ensuring stable power supply to the pantograph body 10. At the same time, the support structure formed by the fixed cylinder 4, the fixed plate 5, and the through hole 24 makes the overall assembly more reliable and reduces maintenance costs.
[0023] The inner bottom wall of the base 1 has two sets of slots 12, and each set of slots 12 has a locking block 13 inside. The upper surface of each locking block 13 is connected to the bottom surface of the carbon skateboard body 2. The outer surfaces of the two grips 9 are fixedly connected with anti-slip pads 23. The inner bottom wall of each slot 12 is fixedly connected with a buffer pad 14. The upper surface of the carbon skateboard body 2 is fixedly connected with a wear-resistant layer 22, which is made of graphite-reinforced composite material. The locking and engagement of the two sets of slots 12 on the inner bottom wall of the base 1 with the locking blocks 13 on the bottom surface of the carbon skateboard body 2 enables precise positioning of the carbon skateboard body 2. The buffer pads 14 on the inner bottom wall of the slots 12 can reduce vibration and impact. The anti-slip pads 23 on the outer surface of the grips 9 can increase hand friction and prevent slippage during operation. The wear-resistant layer 22 of graphite-reinforced composite material on the upper surface of the carbon skateboard body 2 can significantly improve wear resistance and extend service life. At the same time, in conjunction with the original quick-release structure, it balances disassembly and assembly efficiency with usage stability and reduces maintenance costs.
[0024] A pantograph head 11 is fixedly connected to the upper surface of the pantograph body 10. The upper surface of the pantograph head 11 is connected to the bottom surface of the base 1. Mounting plates 15 are fixedly connected to both sides of the base 1. Each mounting plate 15 has mounting holes 16 inside, and each mounting hole 16 has mounting screws 17 inside. A pantograph base 18 is fixedly connected to the bottom surface of the pantograph body 10. Positioning plates 19 are fixedly connected to both sides of the pantograph base 18. Each positioning plate 19 has a set of positioning holes 20 inside. Each positioning hole 20 has a positioning screw 21 inside. The bow head 11 on the upper surface of the pantograph body 10 is connected to the bottom surface of the base 1. With the help of the mounting holes 16 and the internal mounting screws 17 on the mounting plates 15 on the left and right sides of the base 1, the base 1 and the bow head 11 are firmly fixed. The positioning holes 20 and the internal positioning screws 21 on the positioning plates 19 on both sides of the bow seat 18 on the bottom surface of the pantograph body 10 can accurately fix the pantograph body 10. The overall structure ensures the stable operation of the carbon slide plate and is convenient for installation and disassembly, reducing the difficulty of maintenance.
[0025] The working principle of this utility model is as follows: First, the pantograph body 10 is fixed by the positioning plate 19, positioning hole 20, and positioning screw 21 of the pantograph base 18. Then, the base 1 is connected to the pantograph head 11 by the mounting hole 16 and mounting screw 17 of the mounting plate 15 of the base 1. At the same time, the bottom locking block 13 of the carbon slide body 2 is inserted into the slot 12 of the base 1. The buffer pad 14 in the slot 12 plays a buffering role, completing the initial positioning of the whole. Then, the spring 6 on the fixing plate 5 pushes the fixing block 7 into the fixing slot 3 of the carbon slide body 2. The fixing post 8 cooperates with the handle 9 to achieve a stable fixation of the carbon slide body 2 in the base 1. The anti-slip pad 23 on the outside of the handle 9 is convenient to operate and anti-slip. Finally, when it is necessary to disassemble the carbon slide, pull the handle 9. The fixing post 8 drives the fixing block 7 to compress the spring 6 and disengage from the fixing slot 3. Then lift the carbon slide body 2 upward to make the locking block 13 disengage from the slot 12, thus completing the disassembly of the carbon slide. The graphite-reinforced composite wear-resistant layer 22 on the upper surface of the carbon slide body 2 ensures wear resistance during long-term use.
