Description
Technical field
The utility model belongs to coal mine machinery engineering device technique field, in particular to a kind of pulley-type air-door interlocking device
Background technique
Can underground coal mine ventilation equipment really play a role, be an important factor for preventing gas and coal dust severe and great casualty it
One, and the stabilization of air quantity, the safety in production for being reliably then directly related to mine.Due to being interfered by transport, not carrying out between air door can
By interlocking, the phenomenon that underground twice air door often occurs while being opened, causing Air escape branch.Therefore " safety regulations in coal mine " is advised
It is fixed: between air entering and returning well and mainly to need connection roadway to be used between, air return lane, it is necessary to install the positive air door of twice interlocking
And reverse throttle
The air door that China's coal-mine underground uses mainly has common air door and two kinds of self closing door.Although self closing door compares appearance
Easily realize locking, but on the one hand due to its cost it is higher, on the other hand since underground coal mine environment is poor, by vapor, water drenching,
The factors such as coal dust influence, and inconvenient maintenance, performance is unreliable, and service life is shorter.So mechanical locking is more than automatic blocking
It is practical.
Utility model content
The utility model provides a kind of pulley-type air-door interlocking device for the problem present on, by pulley, main
The simple mechanical drive principles such as lock rope, lifting cylinder, cylinder barrel, vertical locking crotch, realize underground air door effectively reliable
It is chain, it effectively prevent twice air door while being opened, cause Air escape branch.
Concrete scheme is as follows:
A kind of pulley-type air-door interlocking device, by pulley, main interlocking rope, lifting cylinder, cylinder barrel, vertical locking crotch group
At；The main interlocking restrict one end be fixed on lifting cylinder on, the other end is connect with air door；Pass through among the main interlocking rope
Pulley changes Impact direction；The cylinder barrel fixation is embedded in ground；The lifting cylinder is moveable suspended in cylinder barrel；
The vertical locking crotch is mounted among two cylinder barrels；The lifting cylinder and cylinder barrel is by being latched crotch vertically come real
Reciprocal interlocking between existing adjacent lifting cylinder；The vertical locking crotch is mounted in fixed plate；The fixed plate is by two
The relatively independent electromagnet of block and intermediate insulating layer composition；The electromagnet is powered by switch control；The switch installation
In inner wall of cylinder, it is connect between electromagnet by electric wire.
Further scheme, there are certain strokes with cylinder barrel bottom for the lifting cylinder.
Further scheme, the vertical locking crotch are isosceles right triangle, and material is iron.
The utility model has the advantages that
1, a kind of pulley-type air-door interlocking device of the utility model realizes air door using simple mechanical drive principle
Sensitive, the degree of reliability of locking further increase.
2, a kind of pulley-type air-door interlocking device of the utility model, production is simple, easy for installation, and failure is few, maintenance capacity
It is small.
3, a kind of pulley-type air-door interlocking device of the utility model has apparent price advantage, every group of air door locking
Device saves 1000 yuan or so than original mode.
4, a kind of pulley-type air-door interlocking device of the utility model, strict control twice air door are simultaneously open, and are shut out
Air flow in laneway short circuit phenomenon absolutely.
Detailed description of the invention

Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below to the utility model
Specific embodiment elaborate.It is practical in order to fully understand to be explained in the following description many details
It is novel.But the utility model can be implemented with being much different from other way described herein, those skilled in the art can
To do similar improvement without prejudice to the utility model connotation, therefore the utility model is not by following public specific reality
Apply the limitation of mode.
Embodiment
1. a kind of pulley-type air-door interlocking device, by pulley 4, main interlocking rope 8, lifting cylinder 7, cylinder barrel 9, vertical locking
Crotch 5 forms；It is characterized by: described main 8 one end of interlocking rope is fixed on lifting cylinder 7, the other end is connect with air door 3；
Impact direction is changed by pulley 4 among the main interlocking rope 8；The fixation of cylinder barrel 9 is embedded in ground；Described
It is moveable suspended in cylinder barrel 9 to go up and down cylinder 7；The vertical locking crotch 5 is mounted among two cylinder barrels 9；The liter
Drop cylinder 7 and cylinder barrel 9 realize the reciprocal interlocking between adjacent lifting cylinder 7 by being vertically latched crotch 5；Described vertically closes
Lock crotch 5 is mounted in vertical locking crotch support device 6；The vertical locking crotch support device 6 is relatively only by two pieces
Vertical electromagnet 6-1,6-2 and intermediate insulating layer 6-3 composition；The electromagnet is controlled by switch 11 and is powered；The switch
11 are mounted on 9 inner wall of cylinder barrel, are connect between electromagnet by electric wire.
Further scheme, there are certain strokes with 9 bottom of cylinder barrel for the lifting cylinder 7.
Further scheme, the vertical locking crotch 5 are isosceles right triangle, and material is iron.
Fig. 1 is twice air door closed state, and lifting cylinder is closed twice air door by self gravity naturally.
Fig. 2 is to promote lifting cylinder by the main chain rope of traction when twice air door is wherein opened together, and lifting cylinder rises
Electromagnetic switch is touched in the process, and electromagnet is powered, and for the vertical crotch magnetic absorption that is latched in electromagnet, the vertical crotch that is latched makes it
The other side is swung to, when air door a period of time to be opened simultaneously, can not continue to be lifted because lifting cylinder is limited by vertical locking crotch, therefore wind
Door one cannot be opened, to realize the interlocking of air door.
