Description

Technical field

The utility model relates to construction vehicles, in particular, artillery guns designed to shoot building elements into the ground.

State of the art

A known method of reducing the speed of two balls moving towards each other in an inelastic collision [1].

This technical solution is based on the law of conservation of momentum.

However, it cannot be applied “directly” to braking the retractable parts of the gun.

There is a method of absorbing recoil energy of a gun due to recoil force arising from the burning of gunpowder in a vessel with a nozzle mounted on the recoil parts of the gun [2]. This method is implemented using the installation for shooting building elements into the ground, which includes an artillery gun, in the barrel of which is installed a ram-piston transmitting energy of powder gases to the building element, and a vessel with a nozzle mounted on the recoil part of the gun.

This technical solution is based on the absorption of recoil energy due to ignition of the powder charge placed in the vessel with the nozzle during the shot and braking of the recoil parts of the gun due to the reactive force created by the outflowing powder gases through the nozzle.

However, for the operation of this prototype installation, a large mass of powder is required, and as a result of this, a lot of noise arises during the outflow of powder gases from the vessel and the high flame column.

The design of the known installation does not allow to absorb the energy of the kickback due to the downhole piston, and also during the operation of the installation insufficient penetration of the piles is achieved.

Utility Model Disclosure

The problem the utility model aims to solve is to develop an installation that uses the absorption energy of the recoil of artillery guns used to shoot building elements into the ground using a ramming piston. This allows you to shoot the pile into the ground to a great depth.

The problem is solved using the signs specified in the utility model formula, common with the prototype, such as an installation for shooting building elements into the ground including an artillery gun, in the barrel of which a ramming piston is used to transmit energy of powder gases to the building element, and distinctive, significant features, such as the barrel, at the muzzle hole is equipped with stops directed into the inside of the barrel, and

the downhole piston is made T-shaped, the shoulders of which, when exiting the bore, interact with the stops of the bore.

The above set of features allows you to get the following technical result - a setup has been created that uses the absorption energy of recoil of artillery guns used to shoot building elements into the ground using a ramming piston, and as a result, this allows you to shoot a building element into the ground to a great depth.

Utility Model Implementation

Installation for shooting construction elements into the ground (Fig. 1) includes an artillery gun in the barrel 1 of which a ram-plunger 2 is installed, which transfers energy of the powder gases to the building element 3 buried in the ground 7. (breech, knurling and guiding tools are not shown in the drawing) . The barrel 1 at the muzzle opening 4 is equipped with stops 5 directed into the inside of the barrel 1. The bore piston 2 is made T-shaped, the shoulders 6 of which, when exiting the barrel 1, interact with the stops 5 of the barrel 1.

Installation works as follows.

The method of absorbing the energy of a recoil of a building artillery gun using a ramming piston is based on the sharp braking of the ramming piston when it passes through the muzzle section of the gun barrel.

The method of absorbing the recoil energy is as follows (see figure 1):

The piston 2, pushing the building element 3 during the shot moves along the channel of the barrel 3 in the direction opposite to the movement of the channel of the barrel 1.

During the passage of the ramming piston 2 through the muzzle 4, the ramming piston 2 is hit by protrusions 6 against the stops 5 made at the muzzle 4 of the gun’s bore 1 and directed inward to the axis of the barrel 1. The recoil energy of the gun is absorbed (see Fig. .2).

The building element is deepened into the ground by absorbing the impact energy of the impact of the moving piston during the shot in the direction opposite to the movement of the barrel with the gun barrel.

The calculations performed for the UZAS-2 installation [3], when using a ramming piston for this purpose show that, as a result of the proposed design of the installation, the absorption of recoil energy can be reduced by up to 40%. This allows you to shoot a building element into the ground to a depth of 20% greater than the installation of the prototype.
