Description
Technical Field
The utility model belongs to the entrance guard field, specifically speaking relates to a pneumatic safety entrance guard device.
Background
The existing entrance guard in the production field of various factory buildings usually adopts a lifting rod type and a push-pull type entrance guard which are driven by a motor. The landing-bar type entrance guard sometimes has a problem that the vehicle is damaged or people are injured by falling of the landing bar while the vehicle and a new vehicle pass through, and the landing-bar type entrance guard needs a sufficient space at the top, and it is sometimes difficult to satisfy this condition in an indoor site. The main disadvantage of the push-pull type entrance guard is that the time for opening and closing the door is relatively long, which seriously affects the traveling efficiency of people and vehicles. In addition, the production site has high requirements on fire and explosion protection, and production personnel usually do not allow the use of live equipment, so the motor-driven entrance guard is not suitable for the fire and explosion protection production site.
For example, chinese patent with application number 2021109422136 introduces an access control system based on face recognition, and adds a damping airbag to the bottom of the rail in the scheme, so as to make up for the disadvantage that a lifting rod type access control damages a vehicle or hurt a person when falling down, but the opening and closing mode of the access control system still can not solve the problem that a larger space is needed above the access control, and therefore the access control system is still not suitable for the use environment of an indoor site.
Therefore, there is a need for an entrance guard design that can be opened and closed quickly, occupies a small space, and can reduce the electrical parts and protect the safety of passing vehicles and pedestrians.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem that prior art exists, the utility model aims to provide a pneumatic safety entrance guard's device.
In order to solve the above problem, the utility model discloses the technical scheme who adopts as follows:
the utility model provides a pneumatic safe entrance guard's device, includes gas holder, stand and gasbag, the gas holder set up in one side of stand, the gasbag set up in the opposite side of stand, the gas holder pass through the pipeline and link to each other with the gasbag, the gasbag on be equipped with the air discharge valve.
And a contraction spring is arranged in the air bag.
And the gas storage tank is provided with a gas transmission valve and a gas exhaust valve.
The gas transmission valve and the exhaust valve are manual valves.
The gas transmission valve and the exhaust valve are electric valves.
The upright post is provided with a sensor.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a gas holder aerifys the gasbag and the opening and close of access control is accomplished in gassing, and the inside of gasbag is equipped with the shrink spring, curls the shrink with the gasbag when gassing, and the sensor that is equipped with when aerifing expands and comes, combines on the stand is automatic aerifys and the gassing. In a production workshop where the use of electricity is completely forbidden, a manual air delivery valve can be adopted to inflate the air bag. The utility model discloses simple structure, convenient operation, the air bag shape transition is fast when aerifing and exhausting to can not have the risk that causes the damage to passing vehicle and pedestrian.

Detailed Description
The present invention will be further described with reference to the following specific embodiments.
Example 1
As shown in fig. 1 and fig. 2, the present invention mainly comprises a gas storage tank 1, a column 4, a gas transmission pipeline 2, an exhaust valve 3 and an air bag 6.
The air storage tank 1 is arranged on one side of the upright column 4, the air bag 6 is arranged on the other side of the upright column 4, the air transmission pipeline 2 is arranged above the air storage tank 1 and connected to the air bag 6, the exhaust pipeline 3 is arranged below the air storage tank 1 and connected to the air bag 6, and the exhaust valve 3 is arranged below the air bag 6.
Meanwhile, the gas storage tank 1 is provided with a gas transmission valve at the gas transmission pipeline 2, and the two valves are manual valves in the embodiment.
The airbag 6 is a rectangular airbag after being completely unfolded, and the width is determined by the width of the intersection needing to be closed. The inside of the air bag 6 is provided with a contraction spring which transversely penetrates through the whole air bag and is bonded with the air bag, so that the air bag 6 is prevented from contracting together with the contraction spring after the contraction spring contracts. The airbag 6 takes up a very small space in a reel shape as shown in fig. 1 after being completely contracted.
When control entrance guard, operating personnel normally closes the door under the condition that the gas transmission valve is opened, and exhaust valve 3 closes, and 6 inside full of gas diastole rectangular shapes of gasbag, the gas transmission valve is closed to the exhaust valve 3 who opens when someone passes through, and along with other discharge valves that pass through in the curling gasbag 6 of shrink spring with gaseous the discharge, the gasbag 6 crouches the back and lets vehicle and pedestrian pass through. After that, the air delivery valve is opened to inflate the air bag 6 until the air bag 6 is fully relaxed.
The exhaust valve 3 shown in the figure does not indicate that the exhausted air returns to the air container 1 again, but only controls the direction of the air exhausted from the air bag 6, if the air container 1 is communicated with the exhaust valve 3, the air exhausting work cannot be completed under the influence of the air pressure in the air container 1.
Example 2
The structure of the present embodiment is substantially the same as that of embodiment 1, except that the sensor 6 is arranged on the upright post 4, and the gas transmission valve and the exhaust valve 3 on the gas transmission pipeline 2 are electrically operated valves.
The sensor 6 controls the gas transmission valve and the exhaust valve 3, when a person and a vehicle pass by, the valves can be automatically opened and closed, the steps of gas charging and discharging are the same as those of the embodiment 1, the gas discharging and charging work of the air bag 6 is completed, and manual control is not needed.
The air bag 6 is a rectangular air bag 6 which is thin after being inflated, so that the air bag is not required to be inflated too much when the air bag is fully relaxed, the entrance guard only has a function of preventing and warning, and the air bag 6 which is very thick is not required to realize a blocking function, so that the air storage tank 1 arranged on the side face can be used for replacing for a long time although the air capacity is limited.
If the air storage tank 1 can be replaced by an air compressor in places where electrical equipment is not particularly strict, maintenance work for inflating and replacing the air storage tank 1 can be saved, and although the air storage tank is no longer suitable for strictly controlling an electrical production site, the air storage tank still has the advantages of small floor area, high opening and closing speed and no damage to pedestrians and vehicles.
