摘要
施工升降机是建筑施工中必不可少的机械设备之一。我国建筑业的蓬勃发展,对施工升降机的性能提出了更高的要求,各类新型施工升降机的研制成为当前建筑机械行业的热点之一。
本课题对施工升降机的总体方案、结构、驱动装置、安全装置分别进行了设计研究。综合比较了几种施工升降机总体方案后,采用钢丝绳卷扬式,其结构简单,受力明确,用户也比较熟悉。安全防坠器、超载保护装置、高度限位装置作为施工升降机的安全保护装置,当施工升降机遇到突发事故时它可以防止吊笼坠落事故的发生,保证人员及货物的安全。在安全保护装置中安全防坠器的作用最为重要,受到了业内人士的广泛重视,因此,对其进行不断地改进以适应行业的发展是十分必要的。本文对现有施工升降机及安全装置进行了深入地分析,研制出了一台施工升降机,为其设计了灵敏度高。可靠性好的安全防坠器及超载保护装置和高度限位装置,并对安全防坠器进行了静力学与动力学分析。
本课题所设计的施工升降机是在现有机型的基础上通过研究设计出的一台起重量大、提升高度高、综合使用性能好的施工升降机,其提升形式采用钢丝绳式,额定起重量为4吨,提升高度为100米。
安全防坠器采用楔块式制动,灵敏度高、可靠性好!结构简单!能够有效地防止吊笼坠落事故的发生。

ABSTRACT
The Construction hoist is one of the essential mechanical devices in the construction. With flourish development of construction industry in our country, higher demands are also asked for the performance and reliability of the construction hoist. Research and development of new type construction hoist has e a lot topic in construction machinery industry.
This topic to the construction elevator overall plan, the structure, the drive, the safety device has separately conducted the design research. After the synthesis pared several kind of constructions elevator overall plan, uses the steel wire to hoist the type, its structure simple, the stress is clear about, the users also familiar. The security guards against falling, the overload protective device, highly the spacing installment takes the construction elevator the safekeeping of security installment which can avoid the failing of the cage to assure the people and goods safety as soon as the construction hoist meets accident. In the modern construction, the safety anti-failing device plays an important role, which has got widely attention by the professional. Therefore, it is very necessary to improve it for fitting the trade needs constantly. This paper aims at these problems, ameliorated the existing construction hoist and the safe
