Abstract
The utility model discloses a mineral floor type integrated outburst-proof air door interlocking device which comprises a base steel plate, wherein the base steel plate is connected with a strut bar; a pulley fixing plate is arranged at the top of the strut bar; the base steel plate is provided with two sliding sleeves; a sliding column is arranged in each sliding sleeve; an angle iron movably-fixing device is arranged between the two sliding sleeves; the angle iron movably-fixing device is connected with a triangular angle iron; and the top of the triangular angle iron is above the two sliding sleeves. Two fixed pulleys are arranged on the bottom of the pulley fixing plate; the two fixed pulleys are respectively wound by a steel wire rope for connecting the air door; and one end of the steel wire rope is connected with a flying ring at the top of the sliding column. By utilizing the structure of the combination of pulleys and levers manufactured by the gravity theory and the lever principle, the mineral floor type integrated outburst-proof air door interlocking device solves the problem that the interlocking of two air doors and the stability of the ventilation system can not be guaranteed due to loosening of the steel wire rope caused by long-time use, and the stability in use is improved greatly.
Description
Technical field
The utility model relates to a kind of mine down-hole ventilation equipment, especially a kind of mining integral type protrusion-dispelling air door interlock that lands.
Background technology
At present, known mine protrusion-dispelling air door (hereinafter to be referred as air door) interlock is to be connected on the twice air door by two wire rope, and is last by wire line hitch that the air door that two wire rope are joined together to form is chain.When drawing back one air door, guarantee that another road air door can not open, thereby it is chain to play the twice air door, block distinguished and admirablely, guarantee the stable effect of ventilation system.But, owing to the long-term unlatching of underground air door, close, cause wire line hitch loosening easily, two wire rope stagger, lax.Form one air door and open, another road air door can be opened a part simultaneously, can not effectively guarantee the reliable and stable of the chain and ventilation system of air door, personnel through the time also cause security incident easily.In addition, the twice wire rope hangs between the twice air door, and is elegant in appearance inadequately, can not meet the requirement of national mine quality standardization fully.
The utility model content
The purpose of the utility model is: a kind of mining integral type protrusion-dispelling air door interlock that lands is provided, and it guarantees the stability of use, meets the requirement of national mine quality standardization, to overcome the deficiency of prior art.
The utility model is achieved in that the mining integral type protrusion-dispelling air door interlock that lands, and comprises the base steel plate, on the base steel plate, is connected with support bar; Be provided with the pulley fixed head at the top of support bar; On the base steel plate, be provided with two sliding sleeves, in each sliding sleeve, be provided with a slide post, between two sliding sleeves, be provided with angle bar activity fastening devices; On angle bar activity fastening devices, be connected with the triangle angle bar, the top of triangle angle bar is in two sliding sleeve tops; Be provided with two fixed pulleys in the bottom of pulley fixed head, on each fixed pulley, be wound with a wire rope that is used to connect air door respectively, an end of wire rope is connected with the suspension ring at slide post top.
Between two sliding sleeves and support bar, be provided with fixed head.Increase the connective stability between two sliding sleeves.
In support bar, be provided with adjusting rod, the top of adjusting rod is connected on the pulley fixed head, between support bar and adjusting rod, is provided with the adjusting bolt.Can come the whole height of modifier through adjustment adjusting rod bar, increase the scope of application.
On the base steel plate, be provided with fixing hole.Conveniently the base steel plate is fixed on the roadway floor.
Owing to adopted technique scheme; Compared with prior art; The utility model utilizes barodynamics principle, the lever of lever principle making and the structure of pulley combination; Solved and caused owing to service time is long that wire rope is loosening can not guarantee the problem that the twice air door is chain and ventilation system is stable, improved the stability of using greatly.The utility model is drawn materials simply, can utilize waste and old steel plate and steel pipe to make.The utility model is simple in structure, and is easy to make, with low cost, and result of use is good.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the lateral view of accompanying drawing 1.
The specific embodiment
The embodiment of the utility model: mining structure of landing integral type protrusion-dispelling air door interlock is as shown in Figure 1; Comprise base steel plate 1, on the base steel plate, produce fixing hole 13, on base steel plate 1, be connected with support bar 2; In support bar 2, be provided with adjusting rod 11; Between support bar 2 and adjusting rod 11, be provided with and regulate bolt 12, above support bar 2, be provided with pulley fixed head 3, the top of adjusting rod 11 is connected the bottom of pulley fixed head 3; On base steel plate 1, be provided with two sliding sleeves 4, between two sliding sleeves 4 and support bar 2, be provided with fixed head 10; In each sliding sleeve 4, be provided with a slide post 5, between two sliding sleeves 4, be provided with angle bar activity fastening devices 6, on angle bar activity fastening devices 6, be connected with triangle angle bar 7, the top of triangle angle bar 7 is in two sliding sleeve 4 tops; Be provided with two fixed pulleys 8 in the bottom of pulley fixed head 3, on each fixed pulley 8, be wound with a wire rope 9 that is used to connect air door respectively, an end of wire rope 9 is connected with the suspension ring at slide post 5 tops.
In use, earlier base steel plate 1 usefulness screw is passed fixing hole 13 and be fixed on the roadway floor, an end of the wire rope 9 on two fixed pulleys 8 respectively is connected on the air door; When one of them air door was opened, the slide post 5 that 9 drives of wire rope are attached thereto rose, and when slide post 5 rises triangle angle bar 7 is pushed up to opposite side; Block the top of another slide post 5, it can't be risen, so just can guarantee that another connected air door can't open; After unclamping air door, the slide post 5 of rise relies on deadweight to descend, thereby air door is closed automatically; Triangle angle bar 7 slowly sets back, and another road air door just can have been opened.Guaranteed that like this twice air door can not open simultaneously, guaranteed the stable of ventilation system.
