设计简介
摘 要
随着世界经济的大繁荣,各个行业都起了翻天覆地的改变,尤其最近几十年以来,世界各国都改变了自己的面貌,无论是在外表还是在社会内层。在这其间,社会的建设少不了各种机械,而在这些机械中,高空作业车的重要性不言而寓。
高空作业车之所以发挥着如此大的作用,跟其自身的特点是分不开的。高空作业车其结构紧凑、传递平稳、操作轻便、举升高,易于实现自动化控制;同时还具有机动灵活、转移速度快的特点。它特别适于从事消防、抢险救灾、施工、安装、维护等工作,广泛应用在电力、摄影、建筑、市政、机场、工厂、园林、住宅等场所。因此,近年来高空作业车发展很迅速,一举成了市政及其他部门主要的高空作业机械。
高空作业车是由升降台和汽车配套改装的高空作业设备。其升降台利用车辆的直流电及引擎动力驱动升降。车辆本身具有行走功能,使得升降台有更好的灵活性和机动性,提高了高空作业的工作效率,能适应区域范围广、流动性大的高空作业。目前最高的达到了70多米。功能上也增加不少,比如增加照明设施,在载人的基础上增加了起重机的功能等。
关键词:高空作业;机械;应用广泛;汽车配套改装。
Abstract
As the world economic prosperity, the each industry has changed turn the world upside down, especially in recent years, all countries in the world have changed their appearance, whether in appearance or in social layer. In the meantime, social construction indispensable to all kinds of machinery, in the machinery, high-altitude vehicles and the importance of the house.
Aerial vehicles can play such a large role, with its own characteristics are inseparable. Aerial vehicle has the advantages of compact structure, smooth transmission, convenient operation, high lift, it is easy to realize automatic control; at the same time also has the advantages of flexibility and mobility, transfer speed. It is especially suitable for engaged in fire, rescue, construction, installation, maintenance and other work, widely used in electric power, photography, architecture, municipal, airport, factory, gardens, residential and other places. Therefore, in recent years, high-altitude operation car development is very rapid, with one action became municipal and other departments of the main aerial work machinery.
Aerial vehicle is composed of lifting platform and automobile accessory adapted to high-altitude operations equipment. The lifting platform with a vehicle and engine power DC drive lifting. The vehicle itself with the walking function, makes the lift table has better flexibility and mobility, improves the operation efficiency, can adapt to a wide range of areas, the mobility of the high-altitude operation. At present, the highest reached more than 70 meters. The function also increased many, such as increased lighting facilities, in the manned on the basis of an increase of crane function
Key words: High altitude operation; machinery; application; automobile accessory modification.
