Description
Technical Field
The invention relates to a self-leveling method for mounting an air door, in particular to a self-leveling method for mounting a pressure balance type air door under a coal mine.
Background
The pressure balance type air door is mainly used for each connection lane between an underground coal mine inlet-return lane and a main air return lane, is a substitute of all the existing air doors, is an ideal air door for the underground coal mine in China, and is wide in application. The conventional damper installation steps are: firstly, carrying out civil engineering work on an installation position according to a preset size, developing a position roadway to a required size, and excavating a groove with a certain size on peripheral roadway arms; secondly, assembling the air door frame to the excavated position, building a wall to fix the air door frame, and thirdly, hinging the air door frame with the air door frame through a hinge; and fourthly, installing other equipment. According to the installation steps, the final effect of the installation of the whole air door is determined by the civil engineering and the installation of the door frame, so that the four frames of the air door frame are ensured to be on the same plane after the installation is finished, and the installation is one of the cores of the installation. The air door, especially the large-area air door can normally work after being installed, the problems that the door leaf is misplaced front and back and is difficult to close, the frame is twisted and the like are solved, after the frame is assembled, the frame needs to be aligned and leveled before the wall is fixed, so that the plane, height, front and back and other dimensions of each part of the frame are within an acceptable error range, and the final fixation is maintained. The conventional alignment leveling can be checked on site by using a portable infrared instrument, and certain requirements are imposed on an operator. Most mines are difficult to implement due to the limitations of coal mines on electrical equipment. There are also bubble pocket levels in the field where measurements are compared, but the level is subject to very large deviations for such large area dampers. In many mines, the alignment is directly dependent on the sight of constructors, and the deviation generated by the alignment is very large. The invention provides a self-leveling method for mounting an air door, which directly and clearly marks whether the air door meets the requirements without depending on external instruments and equipment or depending on personnel experience and operation level.

2) the air door is conveyed to a required installation position in the pit, the air door frame is assembled and erected, the threaded hook of the hanging hammer is screwed into the threaded hanging hole of the hanging ring of the upper cross beam of the air door frame, one end of the hanging wire is connected with the threaded hook, the other end of the hanging wire is connected with the hanging hammer, and the hanging hammer is hung down to complete the arrangement of the hanging hammer;
3) adjusting the air door frame and the horizontal beam until the lower tip of the hanging hammer is in a static state and falls into the calibration hole of the horizontal beam, and the lower tip of the hanging hammer does not touch the bottom and leak outwards;
4) fixing a limiting process beam at a preset position of a wind door frame;
5) observing the alignment condition of the two hanging hammers, and timely adjusting the air door frame according to the deviation condition of the hanging hammers so as to ensure that the two hanging hammers of the air door frame after the wall body is constructed and fixed are both at the required positions of the calibration holes;
6) after the air door frame is fixed with the wall body, the limiting process beam is removed;
7) installing two door leaves, fully opening the door leaves, observing the position condition of the hanging hammer again, and if the hanging hammer has deviation, properly adjusting corresponding hinge of the air door leaf according to the deviation direction;
8) after the wind door frame and the door leaf are installed, the threaded hook, the hanging wire and the hanging hammer are removed, and the horizontal beam is determined to be removed or not according to the requirements of a mine square.
Has the advantages that: the self-leveling method for the air door installation directly and clearly marks whether the air door meets the requirement or not by applying the principle mode of hanging wire hanging hammer calibration to the installation and leveling process of the air door frame body without depending on external instruments and equipment or depending on personnel experience and operation level, can ensure that the air door, particularly a large-area air door can normally work after being installed, does not have the problems of difficult closing of front and back dislocation of a door leaf, frame distortion and the like, and needs to align and level the frame before fixing the base wall after the frame is assembled so as to enable the plane, height, front and back and other dimensions of each part of the frame to be within an acceptable error range and keep the final fixation to be finished.
