Abstract
The utility model relates to a coal mine air door, particularly to a quickly-mounted pressure-resistant air door, which solves the technical problem that the existing air door is easy to damage in case of roadway deformation, and includes an outer frame, an inner frame and two door leaves mounted in the inner frame, wherein a buffering part is arranged between the outer frame and the inner frame; a reverse air preventing baffle plate is arranged at the rotating shaft part of the inner frame; a buffering cushion is arranged on the reverse air preventing baffle plate; and a mechanical reverse-push connecting rod is connected between the door leaves. Compared with the existing air door, the quickly-mounted pressure-resistant air door has excellent pressure property produced in resisting the roadway deformation, and enhances the shock resistance of the door leaves by hitting the anchor rod into the coal layer to fix the door.
Description
Technical field
The utility model relates to the colliery air door, is specifically related to a kind of fast-assembling resistance to compression air door.
Background technology
Along with the thorough change of mining Technology Underground Coal Mine, the driving face of big mining height, big section constantly increases, and the tunnel sectional area reaches more than 22 ㎡; And the current mine air door is divided into wooden air door and irony air door; Wooden air door can also use a period of time after roadway deformation, but affected by environment, and the life-span is not long; Security performance is not enough, has belonged to obsolete product.Effect was pretty good when common irony air door was just installed, and can play the air door effect, but after pressed in a period of time tunnel, air door distortion will be not closed completely, and causing leaks out influence ventilation system and stablize.Because the as easy as rolling off a log breaking-up of air door, ventilation equipment is built repeatedly, not only causes the waste of recruitment and material, and also influence is produced and safety.
Summary of the invention
The utility model provides a kind of fast-assembling resistance to compression air door in order to solve the technical problem that existing air door damages easily after roadway deformation.
The utility model is realized by following technical scheme, and a kind of fast-assembling resistance to compression air door comprises housing, inside casing, reaches two door leafs installing in the inside casing, is buffer part between housing and the inside casing.
The rotating shaft position of inside casing is provided with and prevents the inverted ventilation baffle plate, prevents that the inverted ventilation baffle plate is provided with cushion pad, is connected with the anti-link rod that pushes away of machinery between the door leaf.Be provided with oblique triangular leg at inside casing or housing downside.The door leaf structure is the framework that channel-section steel is made, and skin is a steel plate, and inside is polyamine fat expanded material.
The described quick resistance to compression air door of the utility model adopts big frame to overlap little frame, between frame, uses the structure design of buffer, can make big frame at the laggard row buffering of the pressure that receives roadway deformation, and little mount structure is unaffected, and air door can also normally be opened.Air door is biparting incorgruous synchronous switching, and the interlock effect of utilization mechanical linkages is as long as open the Yishanmen fan; Another road door leaf also synchronous backward is opened; Air door doorframe downside has been installed oblique gusseted structure, can hold up on the spot in the place that needs are installed and lay, and can directly be fixed in the middle of the tunnel during installation; The fixed form of housing adopts and beats the mode that anchor pole enters the coal seam, and fill with polyamine fat expanded material in the slit between doorframe and the tunnel.Can be mainly used between the connection roadway between colliery return airway and the main air intake lane and use.
Compare with existing air door, the pressure performance that the anti-roadway deformation of the utility model produces is good, and the fixed form of door adopts and beats the mode that anchor pole enters the coal seam, has increased the shock proof ability of door leaf.Good leak tightness is installed fast succinctly, need not to build a wall, use cement, has greatly practiced thrift the engineering time; Air door intensity is high, insulation, fire-retardant; Simple in structure, easy care.The down-hole with not only isolated tunnel distinguished and admirable but also can the pedestrian, the ventilation equipment of driving: Fast Installation and can bear the ore deposit and press influence.

Fig. 2 is the A-A sectional drawing of Fig. 1
Among the figure: the 1-base plate, the 2-anchor pole, the 3-housing, 4-wall, the 5-buffer part, the 6-inside casing, 7-door leaf, 8-prevent the inverted ventilation baffle plate, the anti-link rod that pushes away of 9-machinery, the oblique gusseted of 10-, 11-cushion pad.
The specific embodiment
Like Fig. 1,2 signals, a kind of fast-assembling resistance to compression air door comprises housing 3, inside casing 6, reaches two door leafs 7 installing in the inside casing 6, is buffer part 5 between housing 3 and the inside casing 6.
The rotating shaft position of inside casing 6 is provided with and prevents inverted ventilation baffle plate 8, prevents that inverted ventilation baffle plate inboard is provided with cushion pad 11, is connected with the anti-link rod 9 that pushes away of machinery between the door leaf 7.
Be provided with oblique gusseted 10 at inside casing 6 or housing 3 downsides.Can be placed directly on the base plate 1, then assembling fast.Housing 3 is fixed on the wall 4 through anchor pole 2.
Inside casing 6 adopts the steel welding structure with housing 3.Door leaf 7 adopts channel-section steel system skeleton, and 2 ㎜ iron plates are covered in the outside.Shingle nail adopts high strength channel-section steel making framework to cover steel plate outward, the inner polyamine fat expanded material of filling.
