Abstract
The utility model discloses an opening and decompression linkage system of a roadway damper. According to the utility model, a lever handle is mounted on the inner side of a damper handle; a rotation rod is fixed onto the top part of a decompression window; a push rod perpendicular to the rotation rod is fixed onto the rotation rod; the bottom end of the push rod is propped against the decompression window; a first steel wire stay cord is fixed onto the action end of the lever handle; the other end of the first steel wire stay cord is changed in direction by a first fixed pulley, penetrates the damper, and is connected with a pull rod of the decompression window; a lever push handle is mounted on the inner side of the damper; a second steel wire stay cord is fixed onto the action end of the lever push handle; the other end of the second steel wire stay cord is changed in direction by a second fixed pulley, and is also connected with the rotation rod. According to the utility model, the opening and decompression linkage system realizes the linked opening of the damper and the decompression window, the opening procedures of the damper are reduced, the opening resistance of the damper is effectively reduced, and the opening and decompression linkage system is safe, reliable, time-saving, labor-saving, convenient, and fast.
Description
Technical field
The utility model relates to coal mine underground air door.
Background technology
Air door is under coal mine, to be located at the facility that cuts off wind circulation in tunnel and cross vehicle and pedestrian.Owing to being installed in, air door both sides blast in main air entering and returning lane, exploiting field return airway is large, opens difficulty, is unfavorable for that pedestrian or vehicle pass through, and the resistance when reducing door opening, installs and open power-assisted handle, air door pressure release window etc. on general air door.Opening power-assisted handle coordinates air door is pulled at out by leverage two hands; Air door pressure release window is to start pressure release window on the other hand, and another hand catches air door handle firmly to pull open again.Existing pressure release mode needs two hand compounding practices, the inconvenience that operates, time-consuming, effort.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is on the basis of former air door pressure release window, designs a kind of alley way air door and opens pressure release linkage, and no matter outside side sliding door still pushes in inner side, all can realize the united opening of air door and pressure release window.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of alley way air door is opened pressure release linkage, it is, in air door handle inner side, lever type hand handle is installed, fix a bull stick at the top of pressure release sash, on bull stick, fix a push rod vertical with bull stick, the bottom of push rod withstands on pressure release sash; The first steel wire tow line on the effect end of lever type hand handle is fixing, the first steel wire tow line other end is connected on the pull bar of pressure release sash through air door after by the first fixed pulley break-in; Lever type hand handle is installed in air door inner side, and the effect end of lever type hand handle connects upper the second steel wire tow line, and the second steel wire tow line other end is also connected on bull stick after by the second fixed pulley break-in.
While pulling air door, hold grip, the first steel wire tow line pulls pull bar that pressure release window is opened, and realizes the united opening of air door and pressure release sash simultaneously; While promoting air door, depress lever type hand handle, the second steel wire tow line pulls pull bar that pressure release sash is opened, thereby realizes the united opening of air door and pressure release sash simultaneously.
This utility model air door interlock pressure relief device has been realized the united opening of air door and pressure release window, has reduced the unlatching link of air door, has effectively reduced door opening resistance, safe and reliable, time saving and energy saving, convenient and swift.
