Abstract
The invention discloses a mine track vehicle control device for opening and closing an air inlet and outlet door, which is applied to automatic control of an air door for an underground orbit mine car to enter and exit. The main track vehicle control device consists of an intrinsically safe position sensor for mining, a magnet, a spring, a guide sleeve, a rolling wheel, a rolling wheel fixed sleeve, and a connecting frame. The device is arranged between orbits of the air door for the underground mine car to enter and exist in pairs. When the orbit mine car runs to the upper side of the device, the rolling wheel is pressed down, and the spring is compressed and drives the magnet to move downwards; when the magnet moves downwards within an induction range of the position sensor, contacts in the sensor are switched on, the position sensor sends an in-place signal to a controller, the controller automatically opens the air door so as to automatically control the mine car inlet and outlet air door, an external power supply is not needed, and a problem that a control system fails when a disaster happens underground or the external power supply is cut off is solved; and when the tail of the mine car passes through the device on the rear of the air door, the sensor outputs an in-place signal, and the controller automatically closes the air door through delay.
Description
Technical field
The present invention relates to a kind of mining rail vehicle control device that opens and closes the turnover air door, be particularly useful for the automatic control to coal mine underground air door or disaster relief door, also be applicable to the detection to railway system's guideway vehicle.
Background technology
Air door is the important structures in mine ventilation system, is being open to traffic than constructing automatic control storm door on the track lane more frequently.In present mine ventilation system, the application of automatic control storm door is more extensive, and it has not only improved work efficiency, has also guaranteed simultaneously the stable of mine ventilation system.But active mode is adopted in the control of coal mine underground air door at present, and its reliability is low, and poor stability in use for some time, how due to untimely the abandoning of maintenance, does not have the function of initial design at all.
Along with continuing to increase of the coal mining degree of depth, the raising of comprehensive mechanization degree, the mine ventilation amount is also continuing to increase.Cause some areas blast excessive, depend merely on manpower and can't open and close air door, and unfavorable to the maintenance of air door, certain to the stable existence of mine ventilation system threat; In addition, can produce a large amount of toxic and harmfuls and invade to the exploiting field and spread when the disasters such as down-hole presence of fire or gas explosion, thereby causing the poisoning and death by suffocation of personnel in the exploiting field.And mainly there is the problem of following 3 aspects in the air door of current mine track lane use: the unrealized automatic control of (1) existing most of air door, and to depend merely on manpower when pedestrian or mistake car and open and close, labor strength is large, inefficiency; (2) self closing door of part mine adopts photosensor to control trigger source as automatic, but easily is subjected to the impact that smog or dust block to produce misoperation, and handling labor is heavy, and easily causes the control system fluctuation of service; (3) self closing door of part mine is realized automatic control by super sonic, radar microwave detection mode, and the antijamming capability of its frequency modulation emitted wave is strong, and remote control distance is far away, but its detection mode more complicated, and installation and maintenance are more difficult.
Summary of the invention
Technical matters: the objective of the invention is to overcome the weak point in prior art, the mining rail vehicle control device of a kind of simple in structure, stable and reliable for performance, easy accessibility, cheap keying turnover air door is provided.
Technical scheme: the mining rail vehicle control device of keying turnover air door of the present invention, comprise that symmetry is located at Underwell mining into and out of two elasticity sensing mechanisms of air door guide rail inboard, the elasticity sensing mechanism comprises the orienting sleeve that is fixed on the base plate outer end, establish spring in orienting sleeve, be set with the scroll wheel fixed cover that moves up and down along orienting sleeve on spring, the top of scroll wheel fixed cover is provided with scroll wheel; Be provided with the link span that is fixed on base plate between two elasticity sensing mechanisms, the bottom of link span both sides is respectively equipped with the Mine-used I. S position transduser that is connected with controller, the magnet piece that the top of link span both sides is respectively equipped with and is fixed on the scroll wheel fixed cover, move up and down with the scroll wheel fixed cover.
The end face of described scroll wheel is mutually concordant with the end face of track; The model of described type Mine-used I. S position transduser is GUH40.
Beneficial effect: the present invention utilizes the signal output of position transduser to realize mine car is passed in and out the automatic control of air door, need not the additional power source power supply, can solve the down-hole puzzlement that under catastrophe or external power supply powering-off state, control system lost efficacy occurs; The slide block that contacts with orbit mine car adopts the roller form, and the friction force of horizontal direction is reduced to minimum zone, has avoided anchor fitting the phenomenon that misplaces or topple over to occur in the course of the work, and Stability Analysis of Structures is reliable.A mining rail vehicle control device that opens and closes the turnover air door is installed respectively into and out of the position of air door at mine car, can be guaranteed the timely keying of air door, reduced the wait time when mine car passes through air door, improved the work efficiency of colliery system.Filled up the existing vacancy of industry, it is simple in structure, and is stable and reliable for performance, easy for installation, has in the art practicality widely.
