Description

1t The invention relates to mining primarily for the development of deposits of crystalline raw material and ornamental stone, and can also be used in construction for the destruction of foundations of foundations. A known tool for applying profiled recesses on the walls of boreholes, comprising a body connected to a drill rod, a jig and carbide blades | Г1 J. A disadvantage of the known device is the inability to use it for splitting monolithic objects The closest to the proposed and achievable result is A device for directional destruction of monolithic objects, including a drive, sliding cheeks, a spacer wedge installed between the cheeks and connected to the drive, slits The cutting elements oriented in the plane perpendicular to the cheek-separation plane and the device for separate transfer of the load from the expansion wedge to the cutting elements and sliding cheeks, while the drive is made in the form of a power hydraulic cylinder, the wedge is made tetrahedral with different angles of suspension, and the slotted elements are mounted on additional spacer elements installed on the side of the wedge faces with a large angle of suspension C2 J. The disadvantages of the known device are the inability to use and the rotary drive of the drill-machines, as well as the high energy intensity of the process of forming the lead grooves due to the fact that this process is carried out due to the action of a static compressive load from the power cylinder transmitted by the rock elements along the entire length of the drill bit devices. The purpose of the invention is to increase the efficiency of destruction of monolithic objects by allowing the use of a percussive drive. To achieve this goal in a known device for directional destruction of monolithic objects including a drive, sliding cheeks, a spacer wedge installed between the shells and connected to the drive, slit elements oriented in the plane, perpendicular to the plane of the cheek spacing, and device for separate transfer of the load from the spacer wedge to the cutting elements and sliding cheeks, slotted elements are rigidly fixed on the spacer cheeks, the end surfaces of the wedge and cheeks on the drive side are made with counter stops, and the device for separate load transfer is in the form of a removable spacer installed between the wedge and cheek stops. Figure 1 shows a device, a general VIEW} in figure 2 - the same, side view, in FIG. 3 - the lower part of the device with a centralizer; in Figures 4 and 5, sections A-A and BB in Fig. 2, respectively. The device consists of a drive for applying shock loads 1, an adapter 2; spacer wedge 3 with stops 4; removable spacer sleeve 5 with a position lock made with handle 6, valve 7 and bracket 8, sliding cheeks 9 with stops 10, upper 11 and lower 12 lugs, studs 13, nuts 14, springs 15, centralizer 16 with cross-section elements 17, flat springs 18, screws 19, nuts 20, plates 21, bolts 22. The device works as follows. The device assembly is mounted on the hole of the bore-hole, orienting the slotted elements in the chosen direction of splitting, after which the drive 1 applies shock loads, which are transmitted through adapter 2 having a tapered connection with the wedge 3, through the stops 4, the spacer 5, the stops 10 of the sliding cheeks 9 to the centralizer 16, which secured the slotted elements. Under the action of shock loads, the slotted elements 17 form cracks along the walls of the hole in the plane of the intended split. The device works on the formation of slots until the stops 10 of the cheeks 9 rest on the hole of the hole, after the valve 7 is removed from the bracket 8 and the spacer sleeve 5 is removed by the handle 6. The device then works to split the rocks pell

In this way, the expansion wedge 3, under the effect of shock loads transmitted to it from the actuator 1 via the adapter 2, is inserted between the sliding jaws 7 ,. which, moving apart in the radial direction, split the rock ..

The advantage of this device is an increase in the efficiency of the split, as well as the possibility of using as a drive mechanism for applying shock loads of commercially available and widely used jackhammers and perforators.
