The invention relates to the field of motor accessory overhauling and discloses a simple correcting tool for a slide wire of a trolley locomotive. The correcting tool comprises an L-shaped handle, a screw rod, a cross beam, a hook and a supporting piece. The long end of the L-shaped handle is fixedly connected with one end of the screw rod, and a clamping groove is formed in the other end of the screw rod. The screw rod penetrates a nut arranged at the middle portion of the cross beam. Grooves are symmetrically arranged in the cross beam with the nut as the center. One end of the supporting piece is connected with the grooves, and the other end of the supporting piece is connected with the hook. The simple correcting tool replaces traditional manual work for correcting the slide wire, labor force is liberated, and the overhauling time is greatly shortened; and in addition, the simple correcting tool has the beneficial effects that operation is simple and convenient, simplicity and high efficiency are achieved, the labor intensity is greatly lowered, the correcting tool is used for correcting the slide wire so that the bending deformation can be small, use of the slide wire is not affected, and the correcting effect of the slide wire is good.
Description
technical field [0001] The invention relates to the field of maintenance of electric locomotive accessories, and more particularly relates to a simple straightening tool for trolley wires of an overhead electric locomotive. Background technique [0002] A large number of overhead electric locomotives are used in mines to transport ore, waste rock, personnel, materials, etc. The rectifier, the trolley line and the track together form a DC power supply system to provide DC power for the trolley locomotive. After the pantograph of the electric locomotive rises and contacts the trolley line, the electric locomotive is powered on. In actual production, due to factors such as pantograph overturning, external force, and environmental temperature changes, the trolley line will inevitably bend. The existence of bending directly affects the reliable contact between the pantograph and the trolley line. If the speed of the electric locomotive passes through the bending part too fast, i...
