The invention relates to a tool and a method for horizontally adjusting a contact line. The tool for horizontally adjusting the contact line comprises a telescopic rod body and at least two moving wheels, wherein the at least two moving wheels are respectively arranged at two ends of the telescopic rod body. Grooves are formed in the moving wheels in the circumferential direction of the moving wheels, and the walls of the grooves of the moving wheels are used for being clamped on the carrier cable and the contact line respectively. During operation, the structural height of the contact line to be adjusted is determined firstly. According to the structure height of the contact line, the telescopic rod body is adjusted to the proper length, and then the moving wheels at the two ends of the telescopic rod body are clamped to the carrier cable and the contact line respectively and move in the same span in the extending direction of the contact line. And in the moving process, an inspector observes whether the contact line is in a horizontal state. And if the contact line is not in the horizontal state, adjusting the length of the dropper until the contact line is adjusted to the horizontal state. In this way, the contact line is adjusted in an auxiliary mode through the contact line horizontal adjusting tool, errors occurring in the operation process are effectively prevented, and the construction quality and efficiency of a contact network are improved.
本发明涉及一种接触线水平调整工具及方法。接触线水平调整工具包括可伸缩杆体及移动轮,至少两个移动轮分别设于可伸缩杆体的两端。移动轮沿其周向设有凹槽,移动轮的凹槽槽壁分别用于卡在承力索及接触线。作业时,先确认待调整接触线的结构高度。根据接触线的结构高度,调节可伸缩杆体至合适的长度,然后将可伸缩杆体两端的移动轮分别卡在承力索及接触线,并在同一跨距内沿接触线的延伸方向移动。在移动的过程中,检查人员观察接触线是否处于水平状态。若接触线未处于水平状态,调节吊弦的长度,直至接触线调整到水平状态为止。如此,通过该接触线水平调整工具辅助调整接触线,有效防止作业过程中出现的误差,提高接触网的施工质量及效率。
