In order to realize the present invention better, further technical scheme is:
According to one embodiment of the invention, between two calibrated bolcks, add padded coaming.
According to another embodiment of the invention, the face of cylinder of described balancing weight is provided with dismountable carrying bar.
According to another embodiment of the invention, the upper end of described balancing weight is provided with hook.
According to another embodiment of the invention, described shock portion includes three crash panels, and three crash panels are Y-connection, is 120 ° of angles between two crash panels.
The present invention it may also is that
According to another embodiment of the invention, the end face of described three crash panels exceeds the end face of the described barrel other end.
Compared with prior art, one of beneficial effects of the present invention is:
A kind of explosive of the present invention falls the variable loading regulation device of bump test, 1) regulation and control of on-load pressure can convenient and swift be realized, it is not necessary to set up the compression system of complex and expensive；2) if owing to explosive kickback causes that the balancing weight closely coupled with explosive is damaged seriously, individually this balancing weight can be abandoned and more to renew, all the other balancing weights can Reusability, it is to avoid the waste that overall counterweight cannot recycle, and greatly reduces experimentation cost.
