(54) DRILLING CUTTERS FOR DRILLING MACHINES

:. ::.: .. /.

The work is attributed to mining, and to the stands for research and testing of drilling rigs, the processing of individual components, the parameters of the drilling mode and the quality of drilling tools.

Yazyestei bore stand for research of drilling of boreholes, including the frame, the frame, the horn, and the neonomy of the bottom KOKTeihfep with the BZHomi breed, aravl hnt 1.

The only reason for this stand is the absence of the displacement of a container with a block of luxtepeK chj drilling rock and in the vertical direction FOR: drilling of wells without measuring the aggregate of the drill. The stand construction allows the KOHteiteep to be moved with the sideways along the guides in the direction of the drilling axis.

The closest to the claimed meticulous solution is an experimental stand for mining machines, consisting of the base of the rock block, the executing organ, winches, shchravl and tsikh and supporting pyodomit {2.

At this stand, supporting padromats are delivered to the base of the container and can be pulled out of the basement and pass under the conveyor under the destruction strip, on which the executive body is operated by a winch.

The disadvantage of this stand is that stop the testing of drilling rigs, drilling rigs of the drilling machines of the drill. To point iQ a new well, dyperaie

10 shchishvts with start-up and withdrawal of the drilling rig in the setting mode. As a result, in spying rpywo to withstand a constant of boren parameters. In this case, it is impossible to rationally use the surface of the disassembled block due to the fact that the stand with the breed block is fixed on the stand, and the drilling of the wellbore can only be done by permutations and overfills of the level machine.

The aim of the invention is to improve the quality of research and the accuracy of placement of important in a number of.

Goal; This is achieved by the fact that the supporting hydraulic jacks are equipped with support rollers, on which the foundation of the rock block associated with the traction winches is placed, and the external hydraulic jacks are mounted on the moving elements of the supporting hydraulic jacks.

As clamping jacks. Moruta. screw and hydraulic jacks, clamps, etc. are used.

FIG. 1 schematically shows a stand with a partial section to show supporting jacks; W figure 2 - the base of the breed block; on fsg.Z - unit for fixing the base of the rock block on skating rinks.

The stand has a container 1, in which the Breed block 2 is attached by a pressure beam 3 with clamping bolts 4 connected to the container by means of hinges 5. The base of the sometimes block 6 rests on support rollers 7 mounted on a base mounted on the base (1, 8 supporting hydraulic jacks 9 , and is placed in guides 10 with stops 11. For moving the base of the rock block along support rollers in the guides, cable 12 and traction winches 13 are used, which can be driven by an Imufta engine 15 and manually securing the base with a Hb1M block at a certain point is used by clamping jacks 17 mounted on movable elements of supporting jacks 18. The drill 19 is placed in the bunker 20. The actuators of the stand 21 are associated with control and clause 22. The destruction products from the stand removed by sludge duct 23 into shlamasorbak 24..

Bypeime wells in the rock block are as follows. Burits first well. Then c, mother-in-law1; adjusts to drill each subsequent well in accordance with the requirements of the experiment. When drilling parallel wells or gaps, the core 6 raises or lowers on the support KK tracks; 7 supports the power alphanumeric jacks, thus placing the native block 2 in the 19 position. In order to eliminate distortions and displacements & toica 2, the base 6 on the rollers 7 raise and lower the rigid clamping bails 17 BeejpHoe drilling is carried out, then the position of the drilling organ of the drilling crew is completed in accordance with the specified angle.

breeyush When the rock block is installed on a new row or fan of wells, the clamping jacks 17 are disconnected and the rope 12 winches 13; the peeled base 6 is alternated along rotating support rollers 7.

Thus, the vertical movement of the base with the rock block by supporting jacks and the horizontal one - by the rope of the traction winches along the support rollers allows the stand to be drilled at the next well without disrupting the working mode in the silo. Installing the clamping jacks on the movable element of the supporting base with rocks of the HijiM block jacks ensures accurate placement of wells in a row, as it eliminates the possibility of displacement and distortions at the time of vertical displacements of the base with the rock block.

The effect of the application of the proposed stand is in enhancing the quality of the research due to the rigid mounting of the rock block and de-energizing its movements in the vertical horizontal directions on the basis of, which at the same time allows rational distribution of the wells of the surface of the rock block.
