Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution: a labor-saving underground air door switch device can realize the separation of the space of a mine through an underground air door;
the upper end of the door frame body 1 is provided with 3 rotating hinges 2 at equal intervals, the rotating hinges 2 are arranged on the air door body 3, and the air door body 3 is attached to the door frame body 1;
the bearing rolling balls 4 are in rolling connection with the air door body 3 through spherical grooves formed in the air door body 3, and the bearing rolling balls 4 are attached to the door frame body 1;
the observation window 9 is made of transparent glass and is arranged on the door frame body 1;
the method comprises the following steps:
the first electric telescopic rod 5 is installed on the door frame body 1, the first electric telescopic rod 5 is mutually attached to the limiting plate 6 through a groove formed in the limiting plate 6, and the limiting plate 6 is installed on the air door body 3;
the fixing plate 7 is installed on the door frame body 1, the second electric telescopic rod 8 is installed on the fixing plate 7, and the second electric telescopic rod 8 and the air door body 3 are attached to each other;
the sealing cover plate 10 is attached to the door frame body 1, and a pulling handle 11 is installed on the sealing cover plate 10;
in this example, the sealing cover plate 10 is symmetrically provided with positioning rods 12, the positioning rods 12 are mutually attached to the air door body 3, and the outer surfaces of the positioning rods 12 are smooth; the positioning rod 12 is provided with a fixed reed 13, and the fixed reed 13 is arranged on the air door body 3; the sealing cover plate 10 is provided with a sealing strip 14 which is arranged into an annular plate-shaped structure, the sealing strip 14 is made of rubber, and the sealing strip 14 is mutually attached to the air door body 3 through a groove formed in the air door body 3;
however, when the air at the two ends of the air door body 3 needs to be subjected to pre-convection, the pull handle 11 in fig. 3 is pulled, because the pull handle 11 is installed on the sealing cover plate 10, the sealing cover plate 10 starts to be pulled, because the positioning rod 12 is installed on the sealing cover plate 10, and the fixing spring 13 is installed on the positioning rod 12, the fixing spring 13 installed on the positioning rod 12 starts to mutually extrude and deform with the fixing spring 13 installed on the air door body 3, at this time, the sealing cover plate 10 can be taken down, and because the sealing cover plate 10 is installed with the sealing strip 14, the sealing strip 14 also starts to move in the direction far away from the air door body 3, at this time, the convection of the air at the two ends of the air door body 3 can be realized, and the problem that the air door body 3 needs to consume large force due to large air pressure difference when the air door body 3 is subsequently opened is avoided, because the area of the sealing cover plate 10 is small, the sealing cover plate 10 is less stressed, so that the sealing cover plate is easier to pull;
the positioning plate 15 is arranged on the air door body 3, the positioning plate 15 is of a square plate-shaped structure, and a groove with a smooth surface is formed in the positioning plate 15; the positioning plate 15 and the pulling rod 16 are attached to each other, the pulling rod 16 penetrates through the doorframe body 1, a return spring 17 is installed on the doorframe body 1, and the return spring 17 is connected with the pulling rod 16;
when needing to promote air door body 3 and open, make first electric telescopic handle 5 begin work, because the recess of seting up on first electric telescopic handle 5 and the limiting plate 6 is laminated each other, along with the work of first electric telescopic handle 5, first electric telescopic handle 5 just begins to the direction motion of keeping away from limiting plate 6, until first electric telescopic handle 5 no longer laminates with limiting plate 6, then pull pole 16 in the pulling figure 4, make pull pole 16 to the direction motion of keeping away from door frame body 1, because install return spring 17 on the pull pole 16, so return spring 17 just begins by tensile deformation, until pull pole 16 no longer with the recess laminating of seting up on the locating plate 15, just no longer fixed between air door body and the door frame body 1 this moment, thereby be convenient for promote air door body 3.
The working principle is as follows: when needs promote air door body 3, make first electric telescopic handle 5 work, until first electric telescopic handle 5 no longer with limiting plate 6 laminating, pulling pole 16 in the pulling figure 4, make pulling pole 16 no longer laminate each other with locating plate 15, then make second electric telescopic handle 8 work, along with the work of second electric telescopic handle 8, second electric telescopic handle 8 just begins to promote air door body 3, air door body 3 just revolutes and moves hinge 2 and rotate this moment, because install on the air door body 3 and accept spin 4, so accept spin 4 just also to begin to rotate along with air door body 3 is promoted, through the rotation of accepting spin 4, thereby can effectually support air door body 3, thereby be convenient for more and promote air door body 3, this is exactly this laborsaving air door switching device's theory of operation in the pit.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
