SU907173A1 - Device for placing explosives - Google Patents

Description

The invention relates to the mechanization of blasting operations and can be used when laying and restoring channels in difficult-watered and silt soil with a very low bearing capacity in an explosive manner.

Devices are known for deepening rivers and cleaning channels with a hydro-washer mounted on a pontoon, moving through water with the help of korea and HP winches ....

The disadvantage of these devices is the impossibility of self-displacement in silty and watered soils and the laying of linear charges, explosives.

It is also known a device for laying charges of explosives into a swamp, including a self-propelled platform — a pontoon, a cantilever truss, with a mechanism for charging explosives into a well 2.

The disadvantages of the known device are the need to create a preliminary excavation with filling it with water and periodically install the core, as well as the impossibility of using it. use for stacking continuous linear charges of explosives in original packaging, such as bagware, in clay and flooded soils.

The goal is achieved by the fact that the rotating pontoon with rollers rests on separate floats with wedge supports with the possibility of directional movement of hydraulic cylinders through them, with wedge supports placed on the rods of hydraulic cylinders. 3 Fig, 1 shows the proposed device; FIG. 2 is a section A-A in FIG. one . Resistance for laying explosives consists of a swivel pontoon I. in which a silo assembly 2, a hydraulic drive 3, and a loading inert pump f, controlled from the console 5, is installed. 9 frames 10; The integrated hydraulic cylinders I through the rollers 12 with two separate floats 13, having sockets for wedge stops 1, mounted on the rods 15, the wedge stops being controlled by the hydraulic cylinders 1b. The movement of the rotary pontoon 1 relative to the floats 13 is carried out by hydraulic cylinders 17 before and {from below, and the rotation is carried out by hydrocyon-1 -: ApOM -8. The device works as follows: The equipment for zzryvki explosive substances ustanlahvayut along the axis of the subject of the Excavation. Explosive substance;;., Eu: 1 flock is loaded into a hydropoiir cassette b. Hydro-cylinders are actuated and, the rods of which are retracted and separate floats are raised 13. Hydrocyl: -; - drams 1b, wedges Ik are extended and separate floats 13 are lowered, while the pinop is: -. Upzry 1 will not enter the ground and fix them. Water is supplied to the hydrauli-knife cassette 6, which by the polyspast 7 from the hydraulic cylinders 8 of the introduction is inserted into the washed-out ground to a predetermined depth. The hydronum cassette doors open and, leaving the required amount of charge of explosives in the soil, remove it. The lifting hydraulic cylinders 11 and the frame 10 are actuated together with the rotary pontoon 1, the lowering J, which is supported by separate floats 13 by the rollers 12, and is moved to a new position by the rotating cylinder 17 along the guides of separate floats 13 device hydraulic cylinder 18 turn. Using hydraulic cylinders 11 34 raise separate floats 13 and hydraulic cylinders 17 move them to their original position. The lifting rams of the hydraulic cylinders 11 of the lift are retracted, which lower the separate floats 13 and deepen them into the ground, fixing them with wedges, thereby preparing the device for laying explosives. The cycle then repeats, creating a continuously laid chain for charges of explosives into the ground. The travel independent movement of the device through the water is carried out by periodic movement of the wedge lugs 14, which are driven by hydraulic cylinders. 16, and lifting the separate floats13. When the device is transported by any mechanism, the wedge lugs 14 turn and click into the sockets of the separate floats with the hydraulic cylinder 16 without interfering with the movement of the device. A positive effect is achieved by mechanizing the insertion of linear charges of explosives in the original packaging, for example, bagware, etc., into soils with very low carrying D ::; capacity with self-moving device. The invention The device for laying explosives, including a rotary pontoon with a power unit of hydraulic drive and hydraulic erosion, hydraulic blade cassette, is different from The pontoon rollers are supported on separate floats with wedge stops with the possibility of directional movement of hydraulic cylinders through them, moreover, the wedge stops are placed on the rods of hydraulic cylinders.
