Description

Air shaft anti-air door operation structure

Technical Field

The utility model relates to a contrary wind operation technical field of ventilating shaft especially relates to a ventilating shaft contrary wind door operation structure.

Background

When the anti-wind door needs to be lowered in the anti-wind operation, the anti-wind door is tightly sealed, the anti-wind door is attached to the wall of the air duct, and the friction force is large, so that although the winch of the anti-wind door is loosened, the anti-wind door does not normally fall under the action of self gravity.

When the reverse air door is in operation, the reverse air door can only be opened by a tool in the reverse air channel by constructors, and then the constructors put the winch down again after coming out, so that the air door can fall down naturally. By doing so, not only the time is delayed, the requirement of mine wind-reversing in 10 minutes is probably not realized, but also constructors are easy to make mistakes in busy, and the safety risk is realized.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an air shaft anti-air door operation structure in order to compensate the defect of prior art.

The utility model discloses a realize through following technical scheme:

the utility model provides an air shaft air return door operation structure, is including the upper end air return duct and the lower extreme exhaust duct that communicate each other, installs the air return door in the junction of air return duct and exhaust duct, the left end of air return door articulated with the inner wall in air return duct, fixedly connected with winch wire rope above the right-hand member of air return door, the air return duct is worn out behind fixing the leading wheel one on the inner wall of air return duct opposite side to winch wire rope's the other end, is connected with the air return door winch who installs on air return duct outside right side, still fixedly connected with reel wire rope below the right-hand member of air return door, reel wire rope's the other end passes leading wheel two and is connected with electric reel, electric reel install in the outside left side in air return duct, leading wheel two install on the bottom surface.

And a door blocking plate is also fixed on the bottom surface of the exhaust duct.

The electric winding drum adopts a 1.5KW braking motor with a speed reducer as power.

The operation of the original anti-air door is realized by lifting and lowering the winch of the anti-air door. The utility model discloses install an electronic reel again at anti-air door opposite side (1.5 kw takes the brake motor of speed reducer to be power), make a hole at the exhaust duct, pass by wire rope and link to each other through leading wheel two and air door. The operating button of the electric winding drum is put together with the button of the original anti-wind door winch, so that the observation and the operation are convenient.

The utility model has the advantages that: the utility model solves the problem that the anti-wind door in the wind shaft can not fall smoothly due to blocking, and the constructor enters the anti-wind channel and prizes the anti-wind door by the tool to cause the safety risk; the method can completely meet the regulation of changing the wind flow direction of the roadway within 10min required by safety regulations, ensures the intact function of the wind well anti-wind facilities, ensures the perfection and the reliability of the mine ventilation system, solidly lays the foundation of mine safety production and has very important safety benefits.

Drawings

Fig. 1 is a structural diagram of the anti-wind door of the present invention in a normal state.

Fig. 2 is a structural diagram of the anti-wind door of the present invention in the anti-wind state.

Detailed Description

As shown in fig. 1 and 2, an operation structure of a reverse air door of an air shaft comprises an upper reverse air duct 1 and a lower exhaust air duct 2 which are communicated with each other, a back air door 3 is arranged at the joint of the back air channel 1 and the exhaust channel 2, the left end of the back air door 3 is hinged with the inner wall of the back air channel 1, a winch steel wire rope 4 is fixedly connected on the right end of the back air door 3, the other end of the winch steel wire rope 4 passes through the back air channel 1 after passing around a guide wheel 5 fixed on the inner wall of the other side of the back air channel 1 and is connected with a back air door winch 6 arranged on the right side outside the back air channel 1, a reel steel wire rope 7 is fixedly connected below the right end of the backwind door 3, the other end of the reel steel wire rope 7 passes through a second guide wheel 8 to be connected with an electric reel 9, the electric winding drum 9 is arranged on the left side of the outer surface of the reverse air duct 1, and the guide wheel II 8 is arranged on the bottom surface of the exhaust air duct 2.

A door baffle 10 is fixed on the bottom surface of the exhaust duct 2.

The electric winding drum 9 adopts a 1.5KW braking motor with a speed reducer as power.

The anti-wind door winch 6 cooperates with the starting electric reel 9 in a linkage manner, and during the anti-wind operation: transfer anti-wind door winch 6 earlier, if observe 4 loose efforts of winch wire rope, can know that anti-wind door 3 does not fall, start electronic reel 9 this moment after that, under the combined action of the pulling force of electronic reel 9 and anti-wind door 3 gravity, overcome frictional force between air door and wall, the air door descends, can observe that winch wire rope 4 is taut this moment, can close electronic reel 9, by anti-wind door winch 6 free transfer until anti-wind door targets in place. Operation to return to normal position: only the electric winding drum is required to be simultaneously operated to lower and the anti-wind door winch is required to lift.

The method avoids the safety risk of constructors entering the reverse air duct, is simple to operate, safe and reliable, effectively ensures that the air flow direction of the roadway is changed within 10min during mine wind reversal, and obtains good safety management effect in practical application.
