目前,液压支架侧护板在矿井下应用较为频繁,随之引发的问题就是侧护板的变形和损坏等。一旦变形或损坏,侧护板的锁紧装置将失去作用。因为目前液压支架侧护板的主要结构形式为直角式侧护板,而锁紧方式多数采用耳板与销轴的别卡来实现对侧护板的锁紧,带来的问题就是结构变形且发生干涉,造成无法安装等情况。所以,液压支架侧护板锁
At present, the hydraulic support side guards are used more frequently in mines, the consequent problem is the deformation and damage of the side guards. Once deformed or damaged, the locking device of the sideguard will be out of action. Because the main structure of the current side bracket hydraulic bracket for the right-angle side guards, and most of the locking method using the ear plate and pin do not card to achieve the opposite side guards lock, the problem is that the structure is deformed An interference occurred that could not be installed. So, hydraulic bracket sideguard lock
