Description

When conducting emergency rescue operations, it is often necessary to deal with emergency situations when it is necessary to quickly, in a very short, short time move to move or raise voluminous pieces of rubble, sunken equipment, ships, etc., that are too heavy for direct physical impact of people.

The proposed utility model relates to devices for transporting, moving, lifting various cargoes, which are designated by the “jacks" class in engineering, and can be used in emergency rescue operations, mainly as a means capable of carrying out operational work to disassemble the debris resulting from catastrophes, terrorist acts, lifting of sunken ships, pipeline threads from the bottom of reservoirs, rivers, seas.

Known jacks: screw (A.S. USSR No. 1674350, publ. 05/05/74, A.S. USSR No. 2335834, publ. 04/15/79, A.S. USSR No. 4401155, publ. 07.11.91 g, AS USSR No. 4891045, publ. 11/30/93), the working fluid of which is a screw. The disadvantages of screw jacks are: the need for great efforts exerted on the screw head in order to lift or move the load by one thread step; the fragility of the threaded device; the duration of the process of raising or lowering the load; the difficulty of bringing to the jack a device capable of performing work on lifting the load autonomously, i.e. at a distance from the body of exposure; unreliability of safety during prolonged use.

Known jacks: hydraulic (A.S. USSR No. 2715552, publ. 06/23/81, A.S. USSR No. 3743005, publ. 07.03.86, A.S. USSR No. 4679827, publ. 15.04.91 g), the working fluid of which is liquid. The disadvantages of hydraulic jacks are: a very slow process of creating the desired pressure in the liquid to raise or move the load on

set distance; low resource of time of use of sealing gaskets during operation of valves and pistons of the jack; high unreliability of the jack associated with the possibility of leakage of the working fluid through the seal at high pressure; the difficulty of bringing to the jack devices capable of performing work on lifting the load at a distance from the body of influence; unreliability of safety during prolonged use.

Known jacks: thermomechanical (A.S. USSR No. 3979137, publ. 07.04.88, A.S. USSR No. 4647737, publ. 07.05.91, A.S. USSR No. 4903501, publ. 15.11.93 d), the working fluid of which are materials with the effect of shape memory. The disadvantages of thermomechanical jacks are: the length of time required to create the necessary high pressures and temperatures at which lifting or moving the necessary loads is possible; the structural complexity of the devices and the high cost of the working fluid; the complexity of the use of devices for moving or lifting goods over long distances; the difficulty of bringing devices for autonomous control to the jack.

Known jacks: pneumatic (AS USSR No. 5030492, publ. 04/15/94), the working fluid of which is air, gas produced during chemical reactions. The disadvantages of pneumatic jacks are: with prolonged use of the jack in the load, breakthrough of compressed gases from the working chamber through seals is possible; high weight and size parameters of pneumatic devices that do not allow their use in emergency rescue operations; low reliability in ensuring safety during prolonged use; the need for a sufficiently large time to achieve the effect of moving gravity to the desired distance; the difficulty of bringing to the jack devices capable of performing work on lifting the load autonomously; use as a working fluid during emergency rescue operations in confined spaces of environmentally hazardous chemicals and gases.

There is also known a method for lifting goods (AS USSR No. 5030492, publ. 04/15/94), including the preparation and installation of a lifting device, the supply of a working agent to the carrier shell is carried out by gas generation of solid fuel based on alkali, alkaline, azides (tetrozolates) metals. This method provides lifting of the cargo, but cannot be used during rescue operations, because It takes a long time to recharge, clean the chamber of the working fluid from the remnants of a chemical reaction, and utilize reaction products.

Direct analogues of the proposed pyrojack from sources of information have not been identified.

The task the utility model is aimed at reducing time and material costs, creating conditions for comfortable work when lifting or moving gravity, managing work from a distance (autonomously) by simplifying the design of the working body of the jack, increasing its reliability and environmental safety when using it.

The technical result is achieved and lies in the simplicity of the design of the proposed utility model, the bulk of which is made using the same technologies as the breech block with a sleeve receiver and a charger for conventional serial firearms. The design of the utility model contains a bed, mounts, a sleeve with an explosive charge, a piston with a rod, which, after the explosion of the charge due to the release of large kinetic energy, allows the rod to transmit a powerful momentum of force through the piston that can move or lift large loads. Comfort of using the device is achieved by the fact that the proposed design of the jack due to its implementation in the form of a gun barrel with a breech, sleeve case, lock bolt, with a charge with a detonator capsule, which can be activated automatically and autonomously using

radio-controlled signal, allow you to create at very small intervals the necessary pressure to move the piston and the rod, which is in close contact with the load, which simplifies the control of the working fluid of the jack. The device (pyrojack) can be used in the construction of batteries to simultaneously bring them into action when lifting or shifting superheavy loads. As a working fluid in a pyrodompress can be used as serial, environmentally friendly explosives, as well as combustible gases, cylinders with compressed gas. The pyrojack performs a short-term mechanical action on the load to be lifted or moved. The jackscrew is easily disassembled into the main parts, can be stored and transported to the place of use in disassembled form, which increases the convenience when using it.

The proposed utility model is illustrated by drawings, where in Fig.1 shows a General view of the device, in Fig.2 - the use of the device in the form of a battery.

The device (Figure 1) for lifting weights consists of a frame 1, a carriage 2, mounted on a hinge 12 and made integral with the breech 4 of the barrel, the lock-bolt 3, in the breech of the sleeve 5, sleeve 6, chamber 14 for charging an explosive substances, detonator capsule 13, wad-seal 15, piston-projectile 16, rod 9, slots on the rod 7 and the protrusion of the stop on the rod 18, the pressure adjusting screw 11 on the rod, there is a muzzle hole 17 on the barrel 8 for the exit of gases, products explosion and clamps 10 extreme positions of the rod 9.

The sleeve 6 after use can be removed from the sleeve 5 when reloading the jackscrew due to the articulated connection 12 of the gun carriage 2 and the bed 1, as well as the ability of the lock - shutter 3 to be in the open and closed state.

A device for lifting weights (pyrojack) is used as follows.

If it is necessary to lift or move it a certain distance, the bed 1 of the jack is fixed on a powerful fixed stop, for example, the ground or foundation, then the breech part 4 of the jack is charged with a calibrated charge in the sleeve 5, 6, 13, 14, 15, locked with a lock 3 , the hinge 12, the thrust adjusting screw 11 is pressed against the load, which must be set in motion. Then a controlled device sends a signal to the detonator and a shot is fired. Gases, which are formed as a result of the explosion of explosives, having one degree of freedom, directed along the axis of the jack barrel, press on the wad gasket 15, the piston projectile 16 and set the rod 9 in motion with the load. Upon reaching the maximum level of stem outlet - muzzle hole 17, the rod stops at the clamps of the maximum rod output. The process of moving or lifting the load is completed, exhaust gases - explosion products are removed through the muzzle hole 17.

After carrying out work on moving and lifting the load with the help of adjusting bolts, the clamps 10 are released and the rod 9 is returned to its original position.

Since environmentally friendly explosives are used as a working fluid in the pyrodomic jack, the operation of the pyramid ram is environmentally friendly.

When transporting to the place of work or disposal for storage, the pyrod jack can be easily disassembled into the main parts: bed 1; carriage 2; hinge axis 12; a sleeve 6 with a charge of 14 and a wad-seal 15; detonator capsule 13; piston projectile 16; stock 9; pressure screw 11.

The proposed design can be used in the form of a combination of pyrojacks in a battery (Figure 2).

The proposed utility model allows lifting loads of 20-100 tons to a height of 60-200 meters (depending on the design of the barrel and the breech of the device) when calibrated in accordance with the load

the charge of the cartridge, which allows to increase the efficiency of lifting loads when using a jack jack in emergency rescue operations.

In this case, the jacks are assembled into batteries, put into combat readiness, fastened to the ground in the sequence of creating the necessary lifting force to lift or shift a large load. Then, the entire battery is shot simultaneously, or shots in succession at the sections, or at the individual jacks of the sections, and the load being lifted or shifted takes the desired position in space.

In Fig.2 there is a rigging of the platforms - receivers of the load of the battery of pyrojacks with winches, which are able to repel the inertia of the upward moving load. This design allows you to lift sunken loads from the bottom of deep reservoirs, swamps, etc. There are other possible applications of the proposed useful device.
