Description

Mining air door bidirectional adjustable hinge Technical Field The utility model relates to the technical field of mine ventilation equipment, in particular to a bidirectional adjustable hinge for a mine air door. Background Ventilation under coal mine is one of the most basic conditions for ensuring personnel safety and normal production, and a throttle is an important component of ventilation equipment in use. The mine ventilation air door is arranged at a place where the ventilation system is required to cut off the wind flow and pedestrians or vehicles pass through. Because the environment of mine is abominable, moist, corrosive gas content is high, in order to improve the life of mine air door, practice thrift manufacturing cost, current mine air door generally selects the material that density is higher, corrosion resistance is strong to make door frame and door leaf, in order to further improve door leaf life, usually add the metal reinforcing plate on the door leaf, therefore door leaf weight is big, use traditional door leaf hinge to connect door frame and door leaf, often appear operation failure, deformation, door leaf side deviation etc. and reduce door leaf life because of the door leaf overweight, for improving mine air door life and operation flexibility, develop a rational in infrastructure, the hinge that can adjust is very necessary. Disclosure of Invention The utility model provides a mining air door bidirectional adjustable hinge for overcoming the defects in the prior art, which is characterized by comprising the following components: the door frame hinge comprises a steel plate with bolt holes, a door frame rotating shaft sleeve and a rib plate, wherein the door frame rotating shaft sleeve is provided with internal threads; The door leaf hinge comprises a steel plate with a bolt hole and a door leaf rotating shaft sleeve, wherein the door leaf rotating shaft sleeve is provided with a through hole, and two sides of the door leaf rotating shaft sleeve are respectively provided with an adjusting nut; The connecting rod sleeve comprises a connecting sleeve and a screw rod, the connecting sleeve is provided with a through hole, and the screw rod is connected with a door leaf rotating sleeve of a door leaf hinge; the bearing is sleeved on the adjusting bolt; The adjusting bolt sequentially penetrates through the bearing, the connecting sleeve of the connecting rod sleeve and the door frame rotating shaft sleeve, and the top of the adjusting bolt is fixed by the adjusting nut. Furthermore, in order to better realize the utility model, the adjusting bolt is in threaded fit with the door frame rotating shaft sleeve, and the screw rod of the connecting rod sleeve penetrates through the door leaf rotating shaft sleeve and is locked by adjusting nuts at two sides. Furthermore, in order to better realize the utility model, the rib plate of the door frame hinge is welded between the steel plate and the door frame rotating shaft sleeve. Furthermore, in order to better realize the utility model, the adjusting bolt drives the door leaf hinge to move up and down when rotating. Furthermore, in order to better realize the utility model, the adjusting nuts on the two sides of the door leaf hinge can rotate to drive the door leaf hinge to move left and right. The beneficial effects of the utility model are as follows: According to the adjustable hinge, a worker can rotate the adjusting bolt according to the actual installation requirement, so that the door leaf can be adjusted up and down relative to the door frame, the adjusting nut is rotated, the door leaf can be adjusted left and right relative to the door frame, and further the door leaf can be adjusted in two directions, namely, in the horizontal direction and the vertical direction. The flexibility of air door installation is effectively improved, and the tightness of the air door after installation is guaranteed.
