Description
Technical field
The present invention relates to a kind of mortar test devices, more particularly, to a kind of modified mortar test device.
Background technology
Mortar test is a kind of classical way for evaluating military explosive capacity for work, and sample is placed in the explosion chamber of mortar big gun
Middle ignition, explosion product expansion working release bullet, while monitor body swings an angle to negative direction, by the conservation of energy and move
Amount conservation principle finds out work(made by unit mass sample.Mortar big gun is suspended in the swing rope for being about 3.5m in the experimental rig,
Whole device is bulky, and after ignition, mortar big gun negative direction is swung, and measures swing angle, and test process is cumbersome, very not square
Just, the swing of mortar big gun also brings certain security risk.
Chinese patent CN 201408185Y disclose it is a kind of measure pyrotechnic composition emissivity mortar big gun, including gun barrel, gun platform,
Steel ball, the top of gun barrel are the cavitys for placing steel ball, and lower part is powder chamber, and powder chamber is connected to the cavity.On gun platform
There are one the V-shaped groove for determining gun barrel inclination angle, gun barrel is removably attached in the V-shaped groove.By lighting a fuse, ignite
The indoor gunpowder of gunpowder, the emissivity after gunpowder explosion projects steel ball, by measuring the range of steel ball, to calculate the transmitting of gunpowder
Power.In the apparatus, steel ball is gone out by gunpowder explosion impact force, ejection, and the peace to match with its explosive force is needed when experiment
For testing, safety is difficult to ensure the total space.In addition, various regions gravity, air drag have an impact test result, make for a long time
With rear, steel ball is impacted by explosive, is corroded, and damage is made troubles to experiment.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of non-swing angle type mortar big guns
Experimental rig.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of modified mortar test device, including mortar big gun, gun carriage, pedestal and pressure testing system,
Gun carriage one end hinge is connected with pedestal, and the other end is taper horizontal adjustment bolt,
The mortar big gun level is held on gun carriage, and there is front and back two pairs of trunnions, the trunnion to be placed on gun carriage by bearing
The short sliding rail of two couples in,
The vertically-mounted multiplying lever in rear end of the pedestal, a stress point and the breech of the multiplying lever are made
With another stress point and the size and the pressure testing system of duration of record pressure act on.
The upper and lower end face of the short sliding rail is horizontal structure.
The trunnion is set in bearing, upper and lower end face horizontal movement of the bearing along short sliding rail.Mortar big gun edge after ignition
Short sliding rail makees transverse movement, and testing mortar big gun by pressure sensor acts on the power on lever, to calculate capacity for work, with this
Substitute the measurement of pivot angle.
Two pairs of short sliding rails are symmetrical set.
The gun carriage upper surface is equipped with horizon rule, coordinates with horizontal adjustment bolt and adjusts gun carriage level.
The power arm of the multiplying lever be the balance pivot that is connect with pedestal of the lever extremely acted on breech by
Force, resistance arm are the stress point that the balance pivot that connect with pedestal of the lever is extremely acted on pressure testing system, power arm with
Resistance arm proportion of torque is 1:10~1:100.
The pressure that explosion generates is reduced at double, and is transferred to pressure testing system.
The multiplying lever and the stress point of breech effect are rigid support.
The multiplying lever and the stress point of pressure testing system effect are adjustable fulcrum, can be moved up in lever arm
It is dynamic, to adjust pressure scaling.
The pressure testing system is pressure sensor.
Compared with prior art, the present invention is combined by using bearing and short sliding rail, and mortar big gun makees cross along sliding rail after making ignition
To movement, mortar big gun is tested by pressure sensor and acts on the power on lever, to calculate capacity for work, pivot angle is substituted with this
It measures.Due to not having a frame support structure using suspension cable, volume is substantially reduced shared by equipment.In addition, the big gun on rigid gun carriage
Body move distance is very small, will not generate as traditional suspension type mortar test and substantially swing.Use pressure test system
System eliminates the trouble of test pivot angle, including following advantages：
(1) simple structure is stablized, small, can save space；
(2) complicated procedures for avoiding deflection angle measurement substitute deflection angle measurement with pressure sensor；
(3) for mortar big gun without significantly swinging, move distance is small in short sliding rail, safe after igniting；
(4) recoil is reduced at double with lever, to protect pressure sensor；
(5) using the pressure testing system of modernization, test is quick and precisely.

Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
A kind of modified mortar test device, structure is as shown in Figure 1, include mortar big gun 5, gun carriage 11, pedestal 12 and pressure
Sensor 9.Gun muzzle 1 is arranged in the front end of gun carriage 5, and 5 lower section of gun carriage passes through hinge 10 and the horizontal adjustment bolt of taper respectively
14 are connected with pedestal 12.5 level of mortar big gun is held on gun carriage 11, and there is front and back two pairs of trunnions 3, the trunnion 3 to be placed in by bearing 4
In the short sliding rail 2 that two couple on gun carriage 5 is symmetrically set, the upper and lower end face of short sliding rail 2 is horizontal structure, in this way, igniting
Mortar big gun 5 can only be along 2 transverse movement of short sliding rail afterwards.It is also equipped with horizon rule 13 in 11 upper surface of gun carriage, it can be with Level tune spiral shell
It is horizontal that the cooperation of bolt 14 adjusts gun carriage 11.
In the rear end of pedestal 12 vertically through installation multiplying lever 7, the rigid support 6 and breech of the multiplying lever 7
Effect, adjustable fulcrum 8 and the size and the pressure sensor of duration 9 of record pressure act on.The thick stick of multiplying lever 7
Bar fulcrum 15 is arranged in the junction of multiplying lever 7 and pedestal 12.
The present invention is combined by using bearing 4 and short sliding rail 2, and mortar big gun makees transverse movement along sliding rail after making ignition, passes through pressure
Force snesor 9 tests mortar big gun and acts on the power on lever, to calculate capacity for work, the thus function wave of acquisition time-time
Shape substitutes the measurement of pivot angle with this to analyze test result.
The power arm of multiplying lever 7 is that the balance pivot 15 that the lever is connect with pedestal is propped up to the rigidity that breech acts on
Point 6, resistance arm are the balance pivot 15 that is connect with pedestal of the lever to the adjustable fulcrum 8 acted on pressure testing system, dynamic
The arm of force and resistance arm proportion of torque are 1:10~1:100.Ratio is 1 in the present embodiment:20, it can thus pass through unequal arm thick stick
Bar 7 reduces recoil at double, and to protect pressure sensor 9, and the position of adjustable fulcrum 8 can also further adjust.
Due to not having a frame support structure using suspension cable, volume is substantially reduced shared by equipment.In addition, the barrel movement on rigid gun carriage
Distance is very small, will not generate as traditional suspension type mortar test and substantially swing.Using pressure testing system, remove from
The trouble of test pivot angle.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
