Description

Movable air door hinge Technical Field The utility model belongs to the technical field of mine ventilation, and particularly relates to a movable air door hinge. Background In the process of continuously advancing mine exploitation operation, as the roadway gradually extends to the deep part, the number of air doors used for constructing a ventilation system between an air inlet area and an air return area is correspondingly increased. The complicated mine ventilation system has raised extremely high requirement on the reliability of the ventilation facilities, and the reliable ventilation facilities are key points for guaranteeing the safe and stable operation of mine ventilation. However, the hinge currently used for ensuring the rotation part of the air door exposes a certain limitation in practical application, the proportional size of the existing air door frame and the door leaf is difficult to match, and in the practical application process, the perfect installation of the air door frame and the door leaf cannot be ensured after the existing hinge is fixed. Based on this, improvements in damper hinges are needed. Disclosure of utility model In order to solve the technical problems, the utility model provides a movable air door hinge, which ensures that an air door frame and a door leaf are perfectly installed by enabling the air door hinge to move up and down so as to be suitable for an air door with a larger specification. The movable air door hinge comprises a fixed hinge, a movable hinge and a pin shaft, wherein the fixed hinge comprises a hinge piece, the hinge piece is fixed with an air door, the movable hinge comprises a sliding block which is connected to a vertical beam of a door frame in a sliding manner, the sliding block can slide up and down along the vertical beam of the door frame, one side of the sliding block is provided with a fixed block, the fixed block is fixedly connected with an air door wall pile through a fastener, and sleeves are arranged on adjacent sides of the sliding block and the hinge piece, and the two are connected by inserting the pin shaft into the sleeves. Further, the section of the sliding block is groove-shaped, and the groove is buckled on the vertical beam of the door frame. Further, the fixed block is a long rod which is fixed on the air door wall pile through a U-shaped bolt matched with the connecting plate and the nut. Further, an upper sleeve and a lower sleeve are arranged on the sliding block at intervals, a middle sleeve is arranged on the hinge piece, and the middle sleeve is positioned between the upper sleeve and the lower sleeve. Further, the hinge piece is fixed on the air door through a screw. Compared with the prior art, the beneficial effects that have: 1. The hinge is simple in principle and ingenious in design, and flexible adjustment of the hinge position is realized by adding the fastener and the sliding rail structure, so that the gap between the door frame and the door leaf of the air door can be accurately controlled, and perfect fit is ensured. 2. The staff only need adjust the fastener and can easily adjust hinge position, has simplified the installation greatly, has improved work efficiency. 3. The movable air door hinge is flexible in design, can adapt to air door installation requirements of different sizes, and provides more choices for the design and production of the air door.
