施工中运输钢桁架一般采用平板车,如利用混凝土搅拌机行走机构,配上适当夹具亦能解决中小型钢屋架的现场运输问题。江苏省南通市七建第六工程处汪振苏同志著文作了介绍。JG-250混凝土搅拌机行走机构包括前后行走总成,搅拌工作时,全机重及运转荷载系由千斤顶撑脚承担,此时前后行走总成处于休息状态,拆下这对行走总成(包括前轮轴上牵引杆) 于整机工况无影响。拆卸时将主轴两端弹簧上固定轴端的螺栓、螺母解开即可,但应注意机架下垫好方木,加强整机的稳固。
Steel trusses are generally used for flat steel vehicles during construction. For example, the use of a concrete mixer running gear and the appropriate fixtures can also solve the problem of on-site transportation of small and medium sized steel trusses. Comrade Wang Zhensu, the sixth engineer of the Seventh Construction of Nantong City, Jiangsu Province, made an introduction. The running mechanism of JG-250 concrete mixer includes front and rear walking assemblies. When mixing, the weight and operating load of the whole machine are borne by the jack legs. At this time, the front and rear walking assemblies are in a resting state. Remove the pair of walking assemblies (including the front Drawbars on axles have no effect on the whole machine operating conditions. When disassembling, the bolts and nuts at the ends of the shafts at both ends of the main shaft can be unlocked. However, attention should be paid to the fact that the racks are well-matched and the stability of the whole machine is strengthened.
