Preferably, the position of balancing stand 14 can regulate as required, in balancing stand 14, is provided with screw thread, can pass through the position of threaded adjusting balancing stand 14.According to the installation situation of this drop-weight meter, the position of adjustment balancing stand 14 that can be suitable makes drop-weight meter balance, and then makes test have more accuracy.
Percussion device comprises the shock base 51 being arranged on riveting stake base plate 22, clash on base 51 and be provided with removedly and hit column sleeve 52, hit column sleeve 52 and be provided with multiple ventilating microholes 53, hit in column sleeve 52, be provided with outer hit post 54 and in hit post 55, hit outward post 54 hit in being arranged on post 55 directly over and part stretch out and hit column sleeve 52, hit outward post 54 and in hit between post 55 for explosive sample 56 is installed.The setting of ventilating microhole 53, making explosive sample 56 hit post 54 outward at 100 shocks that are subject to dropping hammer hits post 54 outside making and hits gas that under the effect that post 55 moves, explosion time produces inwardly and can discharge and hit outside column sleeve 52, make to hit column sleeve 52, outward hit post 54 and in hit post 55 and avoid the harm that explosive sample 56 explosion times produce, improved hit column sleeve 52, outward hit post 54 and in hit post 55 utilization rate, reduced experimentation cost.
Hit outward post 54, in hit post 55 and hit and between column sleeve 52, have less gap, thereby convenient outer hit post 54, in hit post 55 taking-up with put into, and for explosive sample 56, each test all can produce waste products, being arranged on of gap also reduced to a certain extent explosive sample 56 explosion times externally hit post 54, in hit post 55 and hit the damage that column sleeve 52 causes, and in hit post 55 design be convenient to the explode taking-up of afterproduct of explosive sample 56, reduce explosive sample 56 products externally hit post 54, in the damage of hitting post 55 and hitting column sleeve 52.
In the present embodiment, by the switching of controller 63 pilot relays 62, thereby to the power supply of electromagnet 61 whether to control, when relay 62 closures, electromagnet 61 is switched on and is with and is magnetic, and 100 is adsorbed on electromagnet 61, thereby will drop hammer in the time that relay 63 disconnects, electromagnet 61 power-off demagnetization, lose dropping hammer 100 absorption affinity, electromagnet 61 discharges and drops hammer 100, drops hammer 100 to drop with the form of freely falling body, outside hitting, hit post 54, and then hit explosive sample 56.
The quantity of ventilating microhole 53 can be individual arbitrarily, preferably, the quantity of hitting the ventilating microhole 53 arranging on column sleeve 52 in the present embodiment is four, by four ventilating microholes 53 are set, the waste gas that can make to produce after explosive sample 56 blast completely discharge outer hit post 54, in hit post 55 and hit between column sleeve 52.
Ventilating microhole 53 be oriented along the center up and down of hitting column sleeve 52 upward or outside along hitting column sleeve 52 radial directions.Can need to carrying out according to test towards arranging of ventilating microhole 53, its opening is towards discharging smoothly in atmosphere after 56 blasts of explosive sample as long as ensure.
The position of the inner orifice of ventilating microhole 53 can be at any part of explosive sample 56 present positions, preferably, in the present embodiment, the position of the inner orifice of ventilating microhole 53 is arranged on the middle and upper part of explosive sample 56 present positions, ensure that like this waste gas that explosive sample 56 explosion times produce can get rid of, so avoided explosive sample 56 explosion times hit outward post 54, in the destruction of hitting post 55 and hitting column sleeve 52; The position in the outer aperture of ventilating microhole 53 is exposed is clashing into base 51 and is hitting outside the surface of contact of column sleeve 52, the release of guarantee explosive sample 56 explosion energies like this, alleviate externally hit post 54, in the destruction of hitting post 55 and hitting column sleeve 52.
Because the amount of explosive sample 56 is little, if the aperture of ventilating microhole 53 is excessive, can directly make energy leakage, affect test effect, contrary, the too little meeting in aperture is not gone out energy leakage, and then destroy outer hit post 54, in hit post 55 and hit column sleeve 52.In the present invention, the aperture of ventilating microhole 53 can be for being not more than the arbitrary value of radius of explosive sample 56, preferred, and in the present embodiment, the aperture of ventilating microhole 53 is 0.05 ~ 0.1 times of diameter of explosive sample 56.
The below of hitting column sleeve 52 is provided with the buckle that an annular is protruded, and shock base 51 is provided with the annular slot with buckle consistent size, and buckle is arranged in this draw-in groove removedly.The buckle that annular is protruded and the design of annular slot, can make to hit column sleeve 52 and well be fixed together with clashing between base 51,100 falls and hit outward while hitting post 55 when dropping hammer, and can reduce the destruction to hitting column sleeve 52 and shock base 51.
Drop hammer 100, in the xsect that hits post 55, hit post 54 outward, hit column sleeve 52 and clash into base 51 can be the regular shapes such as square, rhombus, circle, preferably, in the present embodiment, drop hammer 100, in the xsect that hits post 55, hit post 54 outward, hit column sleeve 52 and clash into base 51 be circle, be designed with like this and be beneficial to processing, reduce the use of material, reduce experimentation cost, and circular xsect makes it stressed more even, can reduce spoilage.In addition, the diameter that inside hit post 55, hits post 54 is outward consistent.
Inside hitting post 55 and hitting the material that post 54 adopts is outward GRr15, and hitting column sleeve 52 and clashing into the material that base 51 adopts is GRr15 or T10A.Inside hit post 55, the quenching hardness that hits post 54 and hit column sleeve 52 is 60 ~ 65RC outward.
Preferably, drop hammer 100 quality permissible error scope control below 1 ‰.In general, 100 quality of dropping hammer have following scope, and 10kg drops hammer: (10000 ± 10) g; 5kg drops hammer: (5000 ± 5) g; 2kg drops hammer: (2000 ± 2) g.
Riveting stake base plate 22 is arranged on chassis overhang 31 by anti-slip nut 23, makes to drop hammer 100 to fall to hit and outer hit the rear whole drop-weight meter of post 54 and can ensure to stablize.
The inner side of arbitrary in the two foundation seat steel brackets 21 of left and right is provided with scale 41.0 scale position of scale 41 must with the top of hitting post 54 outward in the same horizontal line, according to the difference of explosive load, scale 41 can move up and down, until 0 scale position of scale 41 and the top of hitting post 54 outward in the same horizontal line, arrange adjustable scale 41 needs of adequacy test well in the present embodiment.
In sum, of the present invention for testing the drop-weight meter of Shock Sensitivities of Condensed Explosives, by drop hammer 100 release of automatic controlling system, can operate at a distance, the huge sound and the harm of harmful gas to human body generation that existing drop-weight meter produces in the time carrying out Shock Sensitivities of Condensed Explosives testing experiment are solved, and by some ventilating microholes 53 being set hitting on column sleeve 52, can make explosive sample 56 in instant of detonation, a small amount of explosion product be got rid of and hit column sleeve 52, thereby reduce the damage of hitting column sleeve 52 parts such as grade, reduced experimentation cost.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the modification that these are equal to or replacement are all included in the application's claim limited range.
