本文介绍北京铁路局和西南交通大学于1973年设计、试制的单主梁C形龙门起重机的设计、试制和试验的情况。试验工作是在安装以后,由铁道科学研究院进行的,包括静刚度、动力刚度和强度试验三部分。这台起重机经过天津火车站使用一年多,证明它具有使用方便、自重轻、效率高、结构新颖、外形美观等优点。为了更好的吸取各方面的意见,我们在对使用单位进行调查访问的基础上,将设计、试制和试验的情况作一简单的介绍,欢迎兄弟单位批评指正。为了说明设计这种龙门起重机的依据,文中首先对国内外龙门起重机在铁路装卸工作中的情况作了扼要的说明。
This article introduces the design, trial production and test of C beam gantry cranes designed and piloted by Beijing Railway Administration and Southwest Jiaotong University in 1973. After the installation of the test work carried out by the Academy of Railway Sciences, including static stiffness, dynamic stiffness and strength test of three parts. After more than a year of using this crane in Tianjin Railway Station, it proved that it has the advantages of convenient use, light weight, high efficiency, novel structure and beautiful appearance. In order to better absorb the opinions of all parties, we make a brief introduction on the design, trial manufacture and test based on the survey and interview of the users. We welcome the criticisms and corrections made by our brother units. In order to illustrate the basis for designing this kind of gantry crane, the article first gives a brief description of the situation of the gantry crane at home and abroad in the railway loading and unloading work.
