Air shaft explosion door automatic opening and closing device
The invention discloses an air shaft explosion door automatic opening and closing device. The air shaft explosion door automatic opening and closing device comprises four stand columns evenly mounted on the edge of a well mouth, a first cross beam and a second cross beam are fixed between every two adjacent stand columns through bolts, and first through holes are formed in the positions, close to the two ends, of the front cross beam and the rear cross beam; and second through holes corresponding to the first through holes are correspondingly formed in cross beams front and back, a hydraulic cylinder penetrates through the first through holes and the second through holes, an inclined strut is integrally formed at the upper end of a cylinder sleeve of the hydraulic cylinder, and the inclined strut is lapped on the first cross beam. An explosion door covers the well mouth, a mounting block is integrally formed on the explosion door, and the extending end of the hydraulic cylinder is fixed to the mounting block through a bolt. The air shaft explosion door automatic opening and closing device has the advantages that quick response can be achieved under the condition that power supply fails, the explosion door can be opened quickly and safely, and triple insurance is achieved.
本发明公开了一种风井防爆门自动开闭装置，包括均匀安装于井口边缘处的四根立柱，两两相邻所述立柱之间均通过螺栓固定有横梁一和横梁二，前后所述横梁一上靠近两端处均开有通孔一，前后所述横梁二上均开有与所述通孔一相对应的通孔二，穿过所述通孔一和通孔二设有液压缸，所述液压缸的缸套上端一体成型有斜撑，所述斜撑搭于所述横梁一上，井口上盖有防爆门，所述防爆门上一体成型有安装块，所述液压缸伸出端通过螺栓固定于所述安装块上面。本发明的优点：在供电出现故障的情况下能快速响应，快速安全地开启防爆门且具有三重保险。
