Description

Technical Field

[0001] The utility model relates to the technical field of contact networks, in particular to a contact network grinding device. Background Art

[0002] The contact network is a high-voltage transmission line that is erected in a zigzag shape above the rails in an electrified railway and is used by the pantograph to draw current. The contact network is the main structure of the railway electrification project and is a special form of transmission line erected above the railway line to supply power to electric locomotives. After the contact network and the pantograph are in contact for a long time, burrs will be generated, resulting in poor contact, so the burrs need to be polished away regularly using a grinding device.

[0003] The existing patent CN208601227 is a contact wire grinder for a rigid contact network, which includes a frame and a traveling mechanism and a grinding mechanism respectively installed on the frame. The grinding mechanism includes a grinding motor and a grinding wheel driven to rotate by the grinding motor. The traveling mechanism includes four pairs of traveling wheels installed at the four corners of the frame, and the wheel surfaces of each pair of traveling wheels are opposite to each other and form a clamping portion. The grinding wheel is installed in the middle of the frame, and the axial direction of the grinding wheel is perpendicular to the axial direction of the traveling wheel so that the steering of the grinding wheel is perpendicular to the traveling direction of the frame.

[0004] The existing technical problems are: the grinding device needs to be slidably hung on the bus to grind the contact network fixed at the bottom of the bus. However, in order to meet the power supply and mechanical segmentation requirements, the contact network is composed of several independent anchor segments. The connecting part of two adjacent anchor segments is called the anchor segment joint. Under the action of the anchor segment joint, the existing grinding device cannot automatically move from the previous bus section to the next bus section. The grinding device needs to be manually removed from the previous anchor segment and then hung on the next anchor segment. During the movement of the grinding device, the on-site operator needs to follow it all the time to remove the grinding device in front of the anchor segment joint in time and then install it on the next anchor segment. This requires the cooperation of multiple people, wastes manpower, is unsafe to operate, and requires high-altitude work, which poses a safety hazard. The metal flying chips generated during the grinding process of the grinding device will affect the working environment of the accompanying operators. Utility Model Content
