国产DCY-450型运梁车,额定载重量450t,曾在秦沈客运专线的施工中用于运送32m跨度的单线箱梁。2003年,铁道部确定客运专线将以32m跨度的双线箱梁为主。为此,需要对DCY-450运梁车进行技术改造,使其可运900t的双线32m跨度箱梁。探讨技术方案的可行性,提出改造的原则,指出改造过程中的技术要点并分别加以计算分析和验证。
Domestic DCY-450-type beam transport vehicles, rated load 450t, once used in the construction of Qin-Shenyang Passenger Dedicated Line 32m span of single-box box girder. In 2003, the Ministry of Railways decided that the passenger dedicated line will be mainly 32m span double-line box girder. To this end, the DCY-450 girder truck needs to be technically rebuilt so that it can carry 900t of two-lane 32m span box girders. Explore the feasibility of technical solutions, put forward the principle of transformation, point out the technical points in the process of transformation and calculate, analyze and verify respectively.
