近年来不少贮木场在卸车、归装作业中采用了龙门吊和装卸桥。从事桥式类型起重机设计的技术人员,在对起重机运行机构的起动打滑、制动打滑验算时,往往通不过。除了部件规格型号大小的选择及其运行机构布置的不合理外,其根本原因是这些公式本身存在一定的问题。本文试图从力学角度出发,结合起重机运行机构的工作特点,推导了起动打滑、制动打滑的验算公式,同时也指出目前常用到的起动打滑,制动打滑验算
In recent years, many storage yard in the dump truck, home operations using gantry crane and loading and unloading bridge. Engaged in the design of bridge type crane technicians, crane operating mechanism in the start skidding, brake skid checking, often pass. In addition to the size of the component specifications and the selection of the operating mechanism of the layout of the unreasonable, the fundamental reason is that these formulas itself there are some problems. This paper attempts to start from mechanics point of view, combined with the working characteristics of crane operating mechanism, derive the starting slip, braking slip formula for checking, but also pointed out that the commonly used to start skidding, brake skid checking
