Problems solved by technology

In this device, the steel ball is ejected by the impact force of the gunpowder explosion. During the test, a safe space matching its explosive force is required for testing, and safety is difficult to guarantee.
In addition, the gravity and air resistance of various places have an impact on the test results. After long-term use, the steel balls are impacted by explosives, corroded and damaged, which brings inconvenience to the test.

Embodiment

[0029] An improved mortar test device, its structure is as follows figure 1 Shown, comprise mortar 5, gun carriage 11, base 12 and pressure sensor 9. The muzzle 1 is arranged at the front end of the gun mount 5 , and the bottom of the gun mount 5 is connected to the base 12 through the hinge 10 and the conical horizontal adjusting bolt 14 respectively. The mortar 5 is placed horizontally on the gun frame 11, and has two pairs of gun lugs 3 at the front and rear. The gun ears 3 are placed in two pairs of short slide rails 2 symmetrically arranged on the gun frame 5 through bearings 4. The short slide rails 2 The upper and lower end surfaces are horizontal, so that the mortar 5 can only move laterally along the short slide rail 2 after detonating. A level ruler 13 is also installed on the upper surface of the gun mount 11, which can cooperate with the level adjusting bolt 14 to adjust the level of the gun mount 11.

Abstract

The invention relates to an improved mortar test device. The device comprises a mortar, a gun carriage, a pedestal and a pressure test system, one end of the gun carriage is connected with the pedestal through a hinge, the other end of the gun carriage is a tapered horizontal adjustment bolt, the motor is horizontally laid on the gun carriage, and has a pair of front trunnions and a pair of rear trunnions, the trunnions are placed in two pairs of short slide rails on the gun carriage through bearings, a multiplying lever is vertically mounted at the rear end of the pedestal, a gun breech is applied to one bearing point of the multiplying lever, and a pressure test system for recording the size of pressure and the duration time is applied to other bearing point of the multiplying lever. Compared with devices in the prior art, the device has the advantages of small size, simple structure, convenience and accuracy in test, and easiness in maintenance.

Description

technical field [0001] The invention relates to a mortar test device, in particular to an improved mortar test device. Background technique [0002] The mortar test is a classic method used to evaluate the working ability of military explosives. The sample is placed in the explosion chamber of the mortar and detonated. The explosion product expands and works to push the projectile out. The principle of conservation of energy and momentum is used to calculate the work done by a sample per unit mass. In this test device, the mortar is suspended on a pendulum rope with a length of about 3.5m. The whole device is bulky. After detonation, the mortar swings in the opposite direction and the swing angle is measured. The test process is cumbersome and very inconvenient. The swing of the mortar It also brings certain security risks. [0003] Chinese patent CN 201408185Y discloses a mortar for measuring the firing force of pyrotechnic powder, which includes a barrel, a barrel, and a...
