Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in fig. 1, for the utility model provides a pneumatic type strikes quick gassing device of platform, quick gassing device include gasbag 6, connect in the gasbag upper plate 7 of 6 upsides of gasbag, connect in gasbag hypoplastron 5 of 6 downsides of gasbag, locate the gasbag closing plate 3 of 7 upsides of gasbag, gasbag closing plate 3 locate the downside of strikeing jar lower cover 1 for the lower extreme opening of sealed impact jar lower chamber 10, gasbag closing plate 3 can follow gasbag 6 fill gassing and reciprocate.
And the lower airbag plate 5 is also provided with a pilot quick exhaust valve 4 for exhausting the airbag 6, and the quick exhaust valve is used for exhausting the airbag 6 when the impact table falls. The pilot quick exhaust valve 4 is controlled by an electromagnetic valve, and the electromagnetic valve is used for controlling the pilot quick exhaust valve 4 to deflate the air bag 6 when the impact table falls.
Still be provided with a plurality of springs 2 between impact cylinder lower cover 1 and the gasbag upper plate 7, the upper end of spring 2 act on impact cylinder lower cover 1, the lower tip of spring 2 act on gasbag upper plate 7, work as gasbag 6 when being in the gas filled state, gasbag closing plate 3 with impact cylinder lower cavity 10 sealed, spring 2 be in by the compression state. The quick deflation device further comprises a plurality of air bag pull rods 8, the upper end parts of the air bag pull rods 8 are connected to the lower cover 1 of the impact cylinder, the lower end parts of the air bag pull rods 8 are fixedly connected to the lower air bag plate 5, the air bag pull rods 8 penetrate through the upper air bag plate 7, and the upper air bag plate 7 can slide up and down along the air bag pull rods 8.
