The invention relates to a forklift pallet fork safety monitoring method which comprises the steps that S1, when a heavy object i is carried, a first fork tooth load pressure value Fi1 and a second fork tooth load pressure value Fi2 are obtained, and the initial value of i is 1; s2, obtaining a conversion frequency ni according to the Fi1 and the Fi2; and S3, the equivalent operation times are obtained, if N is larger than or equal to N0, it is judged that use cannot be continued, otherwise, it is judged that use can be continued, under the condition that use can be continued, the fatigue fracture risk of the pallet fork is judged, the step S1 is returned, and i is equal to i + 1. Compared with the prior art, the force sensor is arranged at the position of the idler wheel on the inner portal frame of the forklift to monitor the stress condition of the pallet fork, whether the pallet fork meets the replacement condition or not is analyzed and judged, pallet fork accidents are avoided, and the use safety of the forklift is improved.
本发明涉及一种叉车货叉安全监测方法,步骤S1、搬运重物i时,获得第一叉齿负载压力值Fi1和第二叉齿负载压力值Fi2,i的初始值为1;步骤S2、根据Fi1和Fi2获得折算次数ni;步骤S3、得到等效作业次数若N≥N0,则判断不得继续使用,否则判断可以继续使用,在可以继续使用的情况下,判断货叉疲劳断裂风险,并返回步骤S1,i=i+1。与现有技术相比,本发明通过在叉车内门架上滚轮处设置力传感器监测货叉受力情况,并分析判断货叉是否达到更换条件,实现避免出现货叉事故,提高叉车使用安全性。
