The invention relates to a rocker self-locking device of an air door, belonging to the field of mine air door auxiliary equipment, in particular relates to a rocker self-locking device for starting an air door, which comprises a wire rope (1), a fixed pulley (2), a cylinder (3), a rocker (6) and a gear (7). The rocker self-locking device for starting the air door is characterized in that one end of the wire rope (1) is connected with an upper part of the air door and passes through the fixed pulley (2), the other end is fixed on the cylinder (3), a left fixed plate (4) and a right fixed plate (5) are fixed at both ends of the cylinder (3), the gear (7) is fixed on the left end surface of the cylinder (3), a resistance gear (8) is mounted on the left fixed plate (4) by a fixed shaft (9) and engaged with the gear (7), and the rocker (6) is welded on the right end surface of the cylinder (3). Compared with the prior art, the invention is convenient to open and close the air door and has the self-locking function and the advantages of simple operation, safety, and the like.
Description
Technical field
The air door rocker self-locking device belongs to Air Throttle in Mine Pit auxiliary equipment field, is specifically related to a kind of rocker self-locking device that is used to open air door.
Background technology
Stable ventilation system is the basis of mine safety work, and the situation that air door need be removed because of haulage device in the down-hole happens occasionally, and has upset normal ventilation system before and after air door is removed, for the safety in production of mine brings unfavorable factor.For this reason, designing unit of the present invention has used super-huge binodal air door, on the stability ground that has guaranteed ventilation system simultaneously, needing in the heavy mechanical equipment transportation to have avoided the problem of regular dismounting air door.But brought the transportation safety problem: when main equipment during through super-huge binodal air door, the upper and lower fan of air door must be opened simultaneously, when equipment passes through; Need the artificial fan body of helping; And going up a fan position height, the artificial difficulty of helping is the bad transportation safety problem that will occur of answering; Not air door to be rushed bad, occur the injury to personnel accident exactly.
The utility model content
The technical problem that the utility model will solve is: overcome the deficiency of prior art, a kind of folding air door of being convenient to is provided, have auto-lock function, safe air door rocker self-locking device simple to operate.
The utility model solves the technical scheme that its technical problem adopted: this air door rocker self-locking device, comprise wire rope, fixed pulley, cylinder, rocking arm, gear, and it is characterized in that: fan on wire rope one end and the air door and link to each other; Behind fixed pulley, the other end is fixed on the cylinder, and left and right sides fixed head is installed at the cylinder two ends; Cylinder left side fixed gear; The resistance gear hobbing is installed on the left fixed head through fixed axis, and and gears engaged, cylinder right side welding rocking arm.
The effect of left and right sides fixed head is to be installed in cylinder on the wall of mine lane.Rocking arm is the collapsible formula.Do not take up room.
Compared with prior art; The beneficial effect that the air door rocker self-locking device of the utility model is had is: the use of this air door rocker self-locking device, avoided the regular generation that is destroyed accident of air door, and avoid the possibility of personnel's injures and deaths in the transportation; Reduced main equipment transportation management link; Guaranteed the safety and the stability of ventilation system, for the safety in production of mine provides logical anti-basis, for mine safety production, carry out production strictly in line with rules and regulations, requisite quality created good condition.

Fig. 2 is the utility model air door rocker self-locking device roller frame sketch map.
Fig. 3 is the utility model air door rocker self-locking device roller frame left view sketch map.
Wherein: 1, wire rope 2, fixed pulley 3, cylinder 4, left fixed head 5, right fixed head 6, rocking arm 7, gear 8, resistance gear hobbing 9, fixed axis.
Fig. 1 is the most preferred embodiment of the utility model air door rocker self-locking device, further specifies below in conjunction with 1～3 pair of the utility model of accompanying drawing:
The specific embodiment
With reference to accompanying drawing 1～3: link to each other fanning on wire rope 1 one ends and the air door, wire rope 1 is through after being fixed on the fixed pulley 2 on top, mine lane and the mine lane wall, and the other end is fixed on the cylinder 3, and cylinder 3 is a tubular, last lay winding wire ropes 1.Left and right sides fixed head 4,5 is installed at cylinder 3 two ends, is installed in cylinder 3 on the wall of mine lane through left and right sides fixed head 4,5.Cylinder 3 left side fixed gears 7, gear 7 is installed on the central axis of cylinder 3, resistance gear hobbing 8 is installed on the left fixed head 4 through fixed axis 9, and with gear 7 reverse engagements, make the gear 7 can only one-directional rotation, play self-locking action.Cylinder 3 right sides welding rocking arm 6, rocking arm 6 collapsible.Rocking arm 6 is present prior aries.Also can adopt other forms of rocking arm, as long as can be with fan open and close on the air door.Be equipped with the motor drives rocking arm, that also can realize fanning on the air door opens and closes automatically.
The operating principle and the course of work are following: when main equipment passes through air door, at first the air door lower fan is opened, with folding rocking arm 6 folding pulling out; Clockwise rotate rocking arm 6 then, wire rope 1 is wound on the cylinder 3, and fan is opened under the draw of wire rope 1 on the air door; When the door opening degree reaches through the requiring of equipment, stop rocking arm 6 and rotate, it is sagging under the deadweight effect that hinder gear hobbing 8 this moment; With sawtooth contraposition on the gear 7, gear 7 is blocked, stop its counter-rotating; Air door is held open state, and personnel can be away from air door, and main equipment can pass through smoothly; When the main equipment material passes through smoothly, at first fan on the air door is closed: on the other hand air door rocking arm 6 self-locking devices resistance gear hobbing 8 is lifted, make sawtooth dislocation on resistance gear hobbing 8 and the gear 7; Another hand rotates counterclockwise rocking arm 6; At this moment, wire rope 1 unclasps, and fan unclasps under the deadweight effect, to fall to wire rope 1 and closes on the air door; Rocking arm 6 bending folds are put into device inside then, close the air door lower fan again.
