Quick positioning device used for tunnel smooth blasting peripheral hole
The invention discloses a quick positioning device used for a tunnel smooth blasting peripheral hole. A first air cylinder is fixedly connected in a bottom plate; the output end of the first air cylinder is penetrated in the bottom plate; the output end of the first air cylinder is fixedly connected with a movement plate; the bottom end of the movement plate is fixedly connected with first self-locking idler wheels; and the bottom end of the bottom plate is fixedly connected with second self-locking idler wheels. The bottom plate is provided with the second self-locking idler wheels, the firstself-locking idler wheels and the second self-locking idler wheels enable the flexibility of the device to be greatly increased, the section shape of each first fixing plate and the section shape ofeach second fixing plate are set to be a circular arc shape, the first fixing plates and the second fixing plates can be effectively laminated with the inner wall of a tunnel, the section shape of a long plate is set to be the circular arc shape, the long plate and the inner part of the tunnel are effectively clamped, two first fixing plates are added to effectively increase the stability of the first positioning plate, and the section shape of each positioning hole is square so as to be convenient in operation during drilling.
本发明公开了一种用于隧道光面爆破周边孔的快速定位装置，所述底板内部固定连接有第一气缸，所述第一气缸输出端贯穿于底板内部，所述第一气缸输出端固定连接有移动板，所述移动板底端固定连接有第一自锁滚轮，所述底板底端固定连接有第二自锁滚轮。本发明通过底板设置第二自锁滚轮，第一自锁滚轮和第二自锁滚轮使该装置的灵活性大大增加，第一固定板和第二固定板的截面形状设置为圆弧形，可以使第一固定板和第二固定板与隧道内壁有效贴合，长条板的截面形状设置为圆弧形，可以使长条板与隧道内部有效卡合，两个第一固定板加入，使第一定位板的稳定性有效增加，定位孔的截面形状设置为方形，在钻孔时，便于操作。
