Abstract
Description
Technical Field
[0001] The utility model relates to the field of pantograph carbon slide plate grinding, in particular to a pantograph carbon slide plate grinding device. Background Technique
[0002] The pantograph carbon slide plate grinding device is a device specifically used for maintaining the pantograph carbon slide plate in the electrified railway. In the electrified railway system, the pantograph (also known as the current collector) contacts the overhead contact line (usually copper or aluminum) to obtain electric energy from an external power source, and then supplies it to locomotives or multiple units for use. The carbon slide plate is one of the key components of the pantograph. It directly contacts the overhead contact line and plays an important role in conducting current. Due to long-term friction with the overhead contact line, the carbon slide plate will gradually wear, and the surface may become uneven or damaged, which will affect the contact quality between the pantograph and the overhead contact line, and further affect the current transmission efficiency and the service life of the pantograph.
[0003] During the general survey and maintenance of subway vehicles, the grinding operation of the pantograph carbon slide plate is involved. The traditional grinding method usually can only grind one side, and it is necessary to separately process the upper surface and the two side edges of the pantograph carbon slide plate, resulting in a cumbersome grinding process and a long time-consuming. During the grinding process, the operator needs to frequently adjust the position and angle of the grinding tool, increasing the operation difficulty and also increasing the risk of safe production. Content of the Utility Model

The middle and both sides of the lower surface of the grinding head are respectively provided with an upper grinding plate groove and side grinding plate grooves. An upper grinding plate is embedded in the upper grinding plate groove. Side grinding plates are embedded in both of the two side grinding plate grooves. The two side grinding plates are obliquely arranged towards the outside of the center of the grinding head and are symmetrically arranged. Threaded holes are opened at the four corners of the upper surface of the upper grinding plate. Threaded through grooves are opened at the positions of the grinding head corresponding to the four threaded holes. A locking bolt is threadedly connected in the middle of the threaded through groove. The upper end of the locking bolt is arranged on the upper surface of the grinding head, and the lower end of the locking bolt is threadedly connected inside the threaded hole.
[0006] Preferably, a wedge-shaped groove is opened at the contact position on the upper side of the grinding head of the side grinding plate groove.
[0007] Preferably, wedge-shaped blocks are fixedly connected to both sides of the upper end of the side grinding plate.
[0008] Preferably, disassembly top holes are provided between the grinding head and the front and rear sides of the side grinding plate groove.
