1、 高压线机械除冰车的设计 Design of Mechanical De-icing Vehicle For High-Voltage Lines I 摘 要 近年来，我国南方部分地区频繁发生雨雪冰冻灾害，导致输电线表面结冰、重 力增大，高压输电线路大面积受损。为了避免高压线被压坏，保证电力输送的正常 进行，就需要将高压线覆冰及时消除。在通过分析现有除冰技术各种利弊后，提出 本文的机械除冰车方案。 本文的目的是设计并制造一种新型的高压线机械除冰车。论文首先提出了除冰 车的整体方案设计及所需解决的主要问题，包括悬挂问题、传动及驱动方式、除冰 刀、行走轮和驱动轮的设计。然后进行了包括轴和除冰刀的设

2、计计算、锁紧机构和 调节机构设计的机械部分设计计算以及控制部分的设计，并给出了轴和除冰刀的加 工工艺。论文最后总结了本设计的创新点及特点，并展示了部分实物及试验照片。 本文设计的高压线除冰车不仅除冰方式独特、除冰效率高，而且其自动调节的 结构可以减少除冰车在除冰时对高压线的损伤，其体积小，方便人工携带，操作简 单，具有广阔的应用前景。 关键词：高压线机械除冰车 机械设计 控制设计 II Abstract In recent years, snow and ice storms occur frequently in parts of southern China. transmission l

3、ines were covered by heavy ice and a large damage was caused . In order to avoid transmission lines being crushed and ensure the normal power transmission, the heavy ice covered in high-voltage must be eliminated in time. So we propose a mechanical de-icing Vehicle in this paper through analyzing va

4、riety of pros and cons of the existing de-icing technology. The purpose of this paper is to design an manufacture a new type of mechanical de-icing vehicle for high-voltage lines. First we proposed a de-icing vehicles overall design and major problems needed to be solved, including the issue of susp

5、ension, transmission and drive, in addition to the design of ice skates, running wheels and driving wheels. Then we design and calculate the mechanical parts of the de-icing Vehicle, include the axis and ice skates, locking and adjusting mechanisms design, and control parts. Then we gave the process

6、ing of axis and ice skate. In the end of the paper, we concludes innovations and show some physical and test photos. The de-icing machinery for high-voltage proposed in this paper not only has unique de-icing way，high de-icing efficiency，but also its the automatic adjustment of the structure can reduce the injury to high-voltage lines during the de-icing，its small size， convenient artificially carry，has wide application prospects.
