The invention relates to an operation and maintenance protection device which comprises a protection frame, the front face of the protection frame is provided with an entrance and exit, the entrance and exit is provided with a main board capable of being opened and closed for protection, the left side and the right side of the entrance and exit are symmetrically and fixedly provided with vertical insertion rods, and the bottom ends of the insertion rods are fixed to the bottom face of the entrance and exit. The left side and the right side of the main plate are symmetrically provided with inserting holes for the inserting rods to be coaxially inserted, and a clamping and locking piece is arranged at the joint of the inlet and outlet and the main plate and used for limiting the vertical freedom degree of the main plate. The main plate is arranged, when the main plate is used for protection during assembly of the protection frame, the main plate is inserted into the insertion rod at the front end of the protection frame through the insertion hole, and the clamping and locking piece used for limiting the vertical degree of freedom of the main plate is arranged at the joint of the entrance and the main plate. The connecting structure is safer and more reliable, and the mainboard is not easy to open by mistake.
本发明涉及一种运维检修防护装置,包括防护架,所述防护架的前面为出入口,所述出入口上设置有用以防护的可开关主板,所述出入口的左右两侧均对称固设有竖直的插杆,所述插杆的底端均固定在出入口的底面,所述主板的左右两侧均对称设置有用以插杆同轴插入的插孔,所述出入口与主板的衔接处设置有卡锁件,用以限制主板的竖向自由度。本发明设置了主板,主板用于防护架组装进行防护使用时,主板通过插孔插接到防护架的前端插杆上,且出入口与主板的衔接处设置有用以限制主板的竖向自由度的卡锁件,与原先的利用转轴和门锁进行固定相比,该连接结构更加安全可靠,主板不容易被轻易误打开。
