摘　　要：介绍了钢管水压机移动机架锁定机构的工作原理,分析了导致锁紧机构卡滞故障频发的主要原因是:锁定机构的插销装置在长期使用过程中出现磨损。采用集成式液压缸装置取代插销装置,彻底消除了因插销装置存在机械磨损量与间隙量造成的不良影响,使得水压机移动机架锁定机构故障发生率为零,提升了运转效率,降低了检修强度和成本。Described here in the paper is the working principle of the mobile stand locking mechanism of the steel pipe hydrostatic testing machine.The main reason for the frequently-happening fault of stuck of the said locking mechanism is identified via analysis,i.e.,the abrasive wear of the mechanism’s pin device due to long term service.Owing to the substitution of the integrated hydraulic cylinder for the pin device,the negative influence by the mechanical wear amount and the gap amount as staying with the said pin device is completely eliminated,and thus the failure rate of the mobile stand locking mechanism of the hydrostatic testing machine is reduced to zero,and as a result the operation efficiency is enhanced,while the intensity and cost of the maintenance are also reduced.
