The invention discloses a hydraulic unloading protection method for fork teeth of a forklift, which is characterized in that a pressure relief device of a pressure relief sensing module is used for relieving pressure, so that the pressure in a hydraulic pushing mechanism can be well buffered under the conditions of misoperation and mistaken touch of the forklift, the damage condition of a hydraulic structure of the forklift is reduced, and the property safety is guaranteed. Meanwhile, the buffering time can also reduce unforeseen circumstances such as goods inclination or collapse caused by fork tooth movement in the carrying process as much as possible, personal safety and goods safety are guaranteed, and safety accidents are reduced; according to the situation that the pushing distances of the hydraulic pushing mechanism are different and the pressure intensity of the hydraulic pushing mechanism is different, an upper limit value is set, a safety range value is set within the upper limit value range, meanwhile, an alarm lamp is arranged to prompt an operator, and the situation that fork teeth move due to accidents in the forklift carrying process is effectively relieved; and when the hydraulic pushing mechanism is stressed, the movement of the hydraulic rod is blocked, so that the risk of explosion or deformation of the hydraulic cylinder occurs.

    本发明公开了一种叉车叉齿的液压卸力保护方法,通过泄压感应模块的泄压装置进行泄压,使液压推动机构内部的压强在叉车出现误操作,误触碰的情况下能够一个很好的缓冲过程,减少叉车液压结构的损坏情况,保障财产安全,同时缓冲时间也能尽量减少搬运过程中因叉齿移动导致的货物倾斜或倒塌等意外情况,保障人生安全和货品安全,减少安全事故;并针对每一次的液压推动机构的推出距离不同,液压推动机构的压强也就不同的情况,设置上限值,并在上限值范围内设定安全范围值,同时配有报警灯,对操作人员进行提示,有效缓解,叉车搬运过程中出现意外导致叉齿移动,液压推动机构受力,液压杆移动受阻,从而出现液压缸爆缸或变形的风险。
