Description
Technical field
This utility model relates to a kind of air bubble discharger, particularly relates to a kind of gun tube and one that bullet is integrated
Formula Heavy duty air big gun discharger.
Background technology
In the impact test of structural member, it is desirable to by larger volume and the object of quality, launch with higher velocity interpolation,
The transient impact power utilizing high-speed object to produce during hitting target etc., completes impact resistance examination and the examination at position each to structural member
Test.
The at present general transmitting using air bubble discharger to complete test object, will compressed gas wink in air chamber
Between discharge, thus promote bullet high-speed motion in gun tube of test object or joint test object, by constantly releasing in air chamber
The gases at high pressure released, make the bullet of test object or joint test object constantly accelerate in gun tube, when test object flies
After going out gun tube, test object hits target with certain speed, thus realizes impact examination and the test of test object, and bullet is then returning
Return in gun tube under the effect of receiving apparatus.
Above-mentioned conventional air big gun discharger is owing to being limited by tradition gun tube structure, when pushing directly on test object,
Need test object to be placed in gun tube, by the gases at high pressure discharged in air chamber, it is achieved test object is in gun tube
Acceleration, but limited by gun tube boundary condition, when needing that the test object of big quality, large volume is carried out impact test
Time, conventional air big gun discharger is then difficult to realize, or is substantially capable of but the design difficulty of device and cost will significantly
Increase.
If it addition, use structure test object being connected by connecting rod with bullet, test object being placed on big gun
Outside pipe, bullet and connecting rod are placed on inside gun tube, utilize gases at high pressure to promote bullet, drive connecting rod and test object one
The mode of superhigh speed motion, although gun tube boundary condition can be solved to by the restriction of test object, but when rate request is higher
Time, the length of gun tube is accomplished by increasing, and the connecting rod between bullet and test object is also required to accordingly increase simultaneously, so exists
Test object rear portion increases a bigger quality, and owing to connecting rod is cantilever position, test object will be made to increase
One bigger moment of flexure, the state even resulting in test is uncontrollable.
To sum up, traditional air bubble discharger is not suitable for the transmitting of the heavy test object of big quality, large volume.
Utility model content

The integral type Heavy duty air big gun discharger that heavy test object is launched.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of integral type Heavy duty air big gun discharger, including gun tube, air chamber and support platform, after the described air chamber of tubulose
End is connected with described support platform, and the middle leading portion external diameter of described air chamber is more than back segment external diameter and forms platform between middle leading portion and back segment
Rank, the front end of described gun tube closes and open rearward end, in the middle leading portion of described air chamber is set in described gun tube and be positioned at described big gun
The posterior segment of pipe, the leading portion periphery of described air chamber is provided with sealing ring, and the surface of described sealing ring is coated with lubricating oil, described gas
Being sealed by described sealing ring between leading portion and the inwall of described gun tube of room, the bottom of described gun tube is provided with roller, described
The front end of gun tube is for contacting with test object.
In said structure, gun tube is installed on air chamber outer so that push directly on test object realize transmitting be one important
Structure change, seal by sealing ring between leading portion and the inwall of gun tube of air chamber, entrance big gun after the release of gas in air chamber
The inner chamber of pipe, necessarily promotes gun tube to move ahead, and under the roller effect bottom gun tube, gun tube can move forward and backward smoothly, completes examination
Test the transmitting of object；Sealing ring and lubricating oil are then conducive to improving sealing effectiveness and reducing frictional resistance.
In order to improve the control accuracy of release gas, the front end in described air chamber is provided with and is made up of front and back's two panels rupture disk
Double rupture disks.
According to application needs, described sealing ring is the multiple of or arranged in parallel.
In order to reclaim gun tube, the left and right sides of described gun tube is provided with the buffer unit for reclaiming；Preferably, described slow
Flushing device is the hydraulic buffer cylinder being connected with air chamber or ground base or rubber damping plate.
The beneficial effects of the utility model are:
This utility model forms new external gun tube by traditional gun tube and bullet being united two into one, and utilizes gun tube
Sealing between inwall and gas chamber outer wall realizes the gas transmitting to gun tube, utilizes gun tube to push directly on test object and realizes at a high speed
The purpose launched, it is to avoid the boundary condition of the gun tube volume constraint to test object, is particularly suited for big quality, large volume
The transmitting of heavy test object；By arranging roller in gun tube bottom, it is to avoid the Moment Influence that test object is additional；By peace
Gun tube reclaims by the buffer unit being contained in the gun tube left and right sides, it is to avoid quality that test object is additional and shock loading
Impact.
