Description

Technical Field

[0001] The utility model relates to the technical field of pantograph cross bracket processing, in particular to a pantograph cross bracket drilling positioning device. Background Art

[0002] A pantograph is a device that receives electrical energy from a circuit while a locomotive or EMU is traveling. When the locomotive or EMU is traveling, the electrical energy from the substation is transferred to the locomotive through friction with the contact wire, so that the locomotive obtains electrical energy. The cross bracket is used to be installed on the upper side of the electric locomotive to facilitate the installation of the pantograph.

[0003] A pantograph cross bracket positioning drilling tool described in publication number CN220575245U includes a main body mechanism, an adjustment mechanism and a limit mechanism, wherein the adjustment mechanism is located on the right side of the main body mechanism, and the limit mechanism is located above the main body mechanism. The main body mechanism includes a device body and a fixing assembly, wherein the fixing assembly is fixedly mounted on the upper end of the device body, and the main body mechanism also includes a fixing bolt, a fixing nut, a nut docking hole and a docking thread, wherein the fixing bolt is fixedly mounted on the upper end of the device body. The pantograph cross bracket positioning drilling tool can fix the pantograph cross bracket with bolts when drilling holes in the pantograph cross bracket, and keep it horizontal, making the operation more convenient, and can avoid the problem that the sliding bar mounting parts of the two cross brackets are not on the same horizontal plane due to inaccurate positioning of the two cross brackets when drilling holes.

[0004] Although the above positioning drilling tooling device solves certain problems, it still has the following disadvantages:

[0005] The cross bracket needs to be connected to the upper surface of the locomotive and a pantograph needs to be installed on its upper side. In order for the pantograph to be able to contact the overhead cables, the pantograph needs to be bent up and down in the longitudinal direction, and the cross bracket needs to be drilled in two mutually perpendicular directions. The above-mentioned positioning drilling tooling can only position the cross bracket in a fixed direction, and drilling in the horizontal direction is inconvenient. Utility Model Content
