The invention discloses a work platform device above a cutting part, the work platform device comprises a platform assembly and a detachable protective guard, the inclination angle of the platform assembly can be automatically adjusted, and the detachable protective guard can be inserted on the platform assembly. According to the operation platform device, the inclination angle of the platform is controlled through support hinging and the leveling oil cylinder, it is guaranteed that the heading machine or the driving and anchoring machine is in a shutdown state, the platform is in a horizontal state all the time, and drilling and anchoring protection operators can stand conveniently. The platform device is designed to be of a two-layer foldable structure, the appearance size is small after folding, the left-right and up-down swing performance of the cutting part is not affected, and normal cutting and topping operation of a drilling and anchoring system of the bolter-miner are not affected; and meanwhile, a rotating structure is designed, the whole platform can rotate through control of a rotary oil cylinder, and the platform can rotate to any position within the range of 0-180 degrees in the using process. And when needed, the protective fence steel pipes are inserted into the second mounting holes and the first mounting holes, so that the safety of the operating personnel standing on the platform can be further improved.
本发明公开一种切割部上方的作业平台装置,作业平台装置包括平台组件和可拆卸式防护栏,所述平台组件可自动调节倾斜角度,可拆卸式防护栏可安插在平台组件上。本发明作业平台装置通过支座铰接及调平油缸控制平台的倾斜角度,保证掘进机或掘锚机在停机状态,该平台始终处于水平状态,便于钻锚护作业人员站立。平台装置设计为两层可折叠结构,折叠后外形尺寸小,不影响切割部左右及上下摆动性能,不影响正常切割及掘锚机钻锚系统打顶作业;同时设计有旋转结构,通过回转油缸控制,可实现平台整体旋转,在使用时,可旋转到0~180°范围内任意位置。在需要时,将防护栏钢管插入第二安装孔及第一安装孔内即可,可进一步提高作业人员站在平台上的安全性。
