Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.
Fig. 1-4 illustrate an embodiment of the present utility model, which is a pneumatic device for controlling a mining push-pull damper.
As shown in fig. 2, 3 and 4, for the working state of the opening motion of the push-pull air door, the specific implementation manner is as follows: the clean air source is more than or equal to 0.3MPa, the pressure air enters the P port of the three-position five-way air control valve and the P port of the button valve through the triplet 102, under the condition that the opposite air door and the door of the opposite air door are closed, the magnetic control valve 201 is closed, the P-A is conducted, the air control valve 108 is pressed and closed, the closed air is discharged through the silencer of the S port of the three-position five-way valve, and the air door is in a non-closed state. When the green button of the air source box is pressed, the air door is opened from the inside, the P-B of the button valve 101 is communicated, air source gas enters the three-position five-way air control valve 106 through one port, the right side of the three-position five-way air control valve 106 is communicated, the P port is communicated with the B port, pressurized air enters the opening of the pneumatic motor 301 through the one-way throttle valve, loop gas returns to the one-way throttle valve through the throttle port of the pneumatic motor 301 to flow through the air control valve 104 and returns to the unit five-way air control valve, and the R port is connected with the silencer to form forward rotation of the loop pneumatic motor 301.
While the motor is transmitting, the pressure gas enters the pneumatic control valve 104 through the tee joint at the opening A, under the condition that the air door is opened, the magnetic control valve 201 is far away from the magnet to restore to the original state, the A-R connected pneumatic control valve 108 loses the pressure to restore to the original state, the R-A is connected, the R opening is provided with a plug, the gas pressure maintaining is blocked out to enter the locking of the other air door control box, the other air door pneumatic control valve 107 is pressed and sucked, the A-R is connected, the P opening is locked, so that the three-position five-way pneumatic control valve of the other air door cannot be sucked, the B opening has no pressure gas, and the locking of the two air doors is realized.
For the working state of the closing movement of the push-pull air door, the specific implementation mode is as follows:
the specific mode is a reverse process of an opening state, only the pneumatic circuit and main motion key points are described, and specific details are not expanded one by one.
The clean air source is more than or equal to 0.3MPa pressure air enters the P port of the three-position five-way air control valve and the P port of the button valve through the triplet 102, under the condition that the opposite air door is closed, the magnetic control valve 201 is attracted, the P-A is conducted, the air control valve 108 is pressed and attracted, the blocking air is discharged through the silencer of the S port of the three-position five-way valve, and the air door is in a non-blocking state. When the red button of the air source box is pressed, P-A of the button valve 101 is connected, air source gas enters the three-position five-way air control valve 106 through one port, the left side of the three-position five-way air control valve 106 is connected, the P port is connected with the A port, pressure air enters the air motor 301 gateway through the one-way throttle valve through the air control valve 104, loop gas returns to the unit five-way air control valve through the air motor 301 opening through the one-way throttle valve, and the S port is connected with the silencer to form reverse rotation of the loop air motor 301.
When the air door is fully closed, the magnetic control valve 201 senses that the magnet 202 on the door frame is attracted, the P-A is conducted, the pneumatic control valve 108 is attracted and connected, the blocking gas is discharged through the opening of the three-position five-way valve 106S, the blocking gas loses the blocking effect when the pressure of the blocking gas is lost, and the air door returns to the initial state. At this time, the button valve 101 is pressed again, and the gas acts on the three-position five-way pneumatic control valve 106 through the magnetic control valve P-A by sucking the magnetic control valve 201, so that the P-A is not conducted any more, the original state is returned, the red button is pressed again, and the motor is not operated any more.
Finally, it is noted that the above-mentioned embodiments are merely for illustrating the technical solution of the present utility model, and that other modifications and equivalents thereof by those skilled in the art should be included in the scope of the claims of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
