Abstract
The invention relates to an air door locking device. The air door locking device comprises a first steel wire rope, a second steel wire rope, a first air door and a second air door. The air door locking device further comprises a first fixed pulley, a second fixed pulley, a first outer sleeve with an upper port closed, a second outer sleeve with an upper port closed, a first inner sleeve, a second inner sleeve, a control arc plate and a steel plate. When the air door locking device is used and one air door is not closed, the other air door can always keep a locked state, and consequently the stability of a ventilation system is effectively ensured.
Description
Technical field
The present invention relates to a kind of blocking device of coal mine equipment, the concrete blocking device that relates to colliery use air door.
Background technology
Under coal mine, in the production operation of mine coal, most important is exactly the normal operation of ventilation system, and first, normal ventilation can guarantee personnel in the pit's the required oxygen of breathing; Second ventilates can discharge the toxic and harmful that down-hole produces, and guarantees normally carrying out of production; Therefore regulating the weather conditions of down-hole, create good operating condition, is the essential condition of Safety of Coal Mine Production.
The distinguished and admirable operating path in down-hole is not certain, people can adjust wind direction, size according to calculating and actual conditions, the mode of adjusting is blocked or is regulated distinguished and admirable by building interim or permanent ventilation equipment exactly, wherein air door is the most common, for guarantee air door running status (as, often open, Chang Guan, a fan open a fan and close etc.), need carry out locking to it, the object of locking is that another pectinid door is not opened when wherein a pectinid door is opened, to guarantee the stable of ventilation system.
Air door is divided into two kinds of shell door and permanent air doors, although shell door as the ventilation equipment of transition stage, effect is the same, the running status no less important of assurance shell door.
At present, the locking of using on shell door under mine is mainly wire rope locking, be exactly to follow closely on two fan shell doors with the wire rope of a certain length, when a pectinid door is opened, another pectinid door is because rope capacity can not be opened not, but wire rope is latched in and while using under mine, has following problem:
Wire rope locking fault rate is higher, and when a pectinid door is not exclusively opened, another pectinid door is likely opened, so that affect the even whole ventilation system of local ventilation system, exists safety in production hidden danger.
Summary of the invention
The object of this invention is to provide a kind of throttle locking device, guarantee latch effect, effectively guaranteed the stable of ventilation system.
Technical scheme of the present invention is as follows: a kind of throttle locking device, described blocking device is connected with the first air door by the first wire rope, by the second wire rope, be connected with the second air door, described blocking device comprises the first fixed pulley, the second fixed pulley, the first outer tube and second outer tube of upper port sealing, the first inner sleeve, the second inner sleeve, control arc sheet, steel plate, described the first outer tube, the second outer tube is vertically welded on steel plate side by side, opposite side is provided with opening, the first inner sleeve, the second inner sleeve is actively socketed on respectively the first outer tube, the second outer tube is inner, end stretches out the first outer tube, the second outer tube, it is fan-shaped controlling arc sheet, its center of circle end is hinged on the first outer tube, the centre position of the second outer tube, the interior spacing that arc length is greater than the first outer tube and the second outer tube is less than olo, the first inner sleeve, the top height of the second inner sleeve is arranged at respectively the centre position of controlling two limits of arc sheet, the first fixed pulley, the second fixed pulley is vertically fixed on respectively the first outer tube, the second outer sleeve upper, with the first air door, the second air door top is parallel, the top that the first wire rope connects the first inner sleeve is walked around the first fixed pulley and is connected on the first air door, the top that the second wire rope connects the second inner sleeve is walked around the second fixed pulley and is connected on the second air door.
Preferably, described the first outer tube, the second outer tube top respectively weld diameter are less than the first steel pipe, second steel pipe of outer tube, the first wire rope, the second wire rope are connected with the top of the first inner sleeve, the second inner sleeve through the first steel pipe, the second steel pipe respectively, and described steel plate is elongated steel sheet.
The throttle locking device that uses invention, has following advantage:
1,, in the situation that a pectinid door is not closed therein, another pectinid door remains that blocking is effectively to have guaranteed the stable of ventilation system;
2, the energy of locking is not subject to have a power failure, blowing-out is overhauled affects;
3, blocking time is long, has effectively guaranteed the stability of ventilation system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is used view for opening the first air door;
Fig. 3 is used view for opening the second air door.
The specific embodiment
As shown in Figure 1, a kind of throttle locking device, described blocking device is connected with the first air door 1 by the first wire rope 9, by the second wire rope 10, be connected with the second air door 2, described blocking device comprises the first fixed pulley 11, the second fixed pulley 12, the first outer tube 3 and second outer tube 4 of upper port sealing, the first inner sleeve 5, the second inner sleeve 6, control arc sheet 7, steel plate 8, described the first outer tube 3, the second outer tube 4 is vertically welded on steel plate 8 side by side, opposite side is provided with opening, the first inner sleeve 5, the second inner sleeve 6 is actively socketed on respectively the first outer tube 3, the second outer tube 4 inside, end stretches out the first outer tube 3 and the second outer tube 4, it is fan-shaped controlling arc sheet 7, its center of circle end is hinged on the centre position of the first outer tube 3 and the second outer tube 4, the interior spacing that arc length is greater than the first outer tube 3 and the second outer tube 4 is less than olo, the first inner sleeve 5, the top height of the second inner sleeve 6 is arranged at respectively the centre position of controlling 7 two limits of arc sheet, the first fixed pulley 11, the second fixed pulley 12 is vertically fixed on respectively the first outer tube 3, the second outer tube 4 upper ends and the first air door 1, the second air door 2 tops are parallel, the top that the first wire rope 9 connects the first inner sleeve 5 is walked around the first fixed pulley 11 and is connected on the first air door 1, the top that the second wire rope 10 connects the second inner sleeve 6 is walked around the second fixed pulley 12 and is connected on the second air door 2, described the first outer tube 3, the second outer tube 4 tops respectively weld diameter are less than the first steel pipe 13 of outer tube, the second steel pipe 14, the first wire rope 9, the second wire rope 10 is respectively through the first steel pipe 13, the second steel pipe 14 and the first inner sleeve 5, the top of the second inner sleeve 6 connects.
