装载机发动机机罩门开启后若机无固定支撑,可能存在人身安全风险。国家标准在《GB/T17300-2010土方机械通道装置》要求,“在机器操作期间为使机壳门始终开着,应提供一个使其固定在开启位置的装置,并且该装置应能承受300N的关闭力”。目前一些装载机发动机机罩门采用气弹簧式支撑杆,该种支撑杆成本较高,长期使用后其弹性可能失效,使机罩门失去支撑作用,从而存在安全隐患。我公司某型装载机发动机机罩门采用撑杆式支撑机构,其主要由U形支
Loader engine hood door open if the machine without a fixed support, there may be personal safety risk. National standards In the “GB / T17300-2010 earth moving machinery access device” requirements, “in the operation of the machine to keep the cabinet door always open, should be provided with a fixed in the open position of the device, and the device should be able to withstand 300N The closing force ”. At present, some engine covers for loaders use gas spring-type support rods. Such support rods have high cost. After long-term use, their flexibility may fail, causing the support doors to lose their supporting function, thereby posing a potential safety hazard. A certain type of loader engine hood door uses strut-type support mechanism, which is mainly composed of U-shaped branch
