【正文】 高壓線機械除冰車的設計 Design of Mechanical Deicing Vehicle For HighVoltage Lines I 摘 要 近年來，我國南方部分地區(qū)頻繁發(fā)生雨雪冰凍災害，導致輸電線表面結(jié)冰、重力增大，高壓輸電線路大面積受損。為了避免高壓線被壓壞，保證電力輸送的正常進行，就需要將高壓線覆冰及時消除。在通過分析現(xiàn)有除冰技術各種利弊后，提出本文的機械除冰車方案。 本文的目的是設計并制造一種新型的高壓線機械除冰車。論文首先提出了除冰車的整體方案設計及所需 解決的主要問題，包括懸掛問題、傳動及驅(qū)動方式、除冰刀、行走輪和驅(qū)動輪的設計。然后進行了包括軸和除冰刀的設計計算、鎖緊機構和調(diào)節(jié)機構設計的機械部分設計計算以及控制部分的設計，并給出了軸和除冰刀的加工工藝。論文最后總結(jié)了本設計的創(chuàng)新點及特點，并展示了部分實物及試驗照片。 本文設計的高壓線除冰車不僅除冰方式獨特、除冰效率高，而且其自動調(diào)節(jié)的結(jié)構可以減少除冰車在除冰時對高壓線的損傷，其體積小，方便人工攜帶，操作簡單，具有廣闊的應用前景。 關鍵詞： 高壓線機械除冰車 機械設計 控制設計 II Abstract In recent years, snow and ice storms occur frequently in parts of southern China. transmission lines 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 highvoltage must be eliminated in time. So we propose a mechanical deicing Vehicle in this paper through analyzing variety of pros and cons of the existing deicing technology. The purpose of this paper is to design an manufacture a new type of mechanical deicing vehicle for highvoltage lines. First we proposed a deicing vehicle’s overall design and major problems needed to be solved, including the issue of suspension, 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 deicing Vehicle, include the axis and ice skate’s, locking and adjusting mechanism’s design, and control parts. Then we gave the processing of axis and ice skate. In the end of the paper, we concludes innovations and show some physical and test photos. The deicing machinery for highvoltage proposed in this paper not only has unique deicing way， high deicing efficiency， but also its the automatic adjustment of the structure can reduce the injury to highvoltage lines during the deicing， its small size， convenient artificially carry， has wide application prospects.
