SU95504A1 - Horizontal well drilling machine - Google Patents

Description

The subject of the invention is a machine for horizontal drilling of wells under railway and other earth bed.

In the known machines of this kind, the G1S is broken; delivery and its removal from the drill are carried out hydraulically, which causes a considerable consumption of water operating under a pressure of 6-7 atm. Therefore, in places remote from water bodies or water supply networks, meeting the need for drilling water is a costly and time consuming task.

Ryobretenke pre ;; sees the production of the horizon.; 11 south of drilling without water.

This is achieved by using a column of a new drill, inside which two fires are attached to the bottom part of the drill, located opposite each other, having a helical surface and predetermined for destroying the rock and supplying it by an amount equal to the length of the blades and the scraper traysport to transport the destroyed rock to the mouth wells.

The drawing shows a longitudinal section n partially side view of the proposed machine.

The machine used a core drill 1 e drill head 2, placed on roller or ball bearings 3, which are used to guide and reduce friction during rotation of the core drill. In the bottom-hole part, two knives 4, opposite to each other, having a helical surface, are in the way to the column drill Irnkrepley. 4 are intended to destroy the iodine and feed it along the longitudinal axis of the drill by an amount equal to their length.

In order to transfer the rasten-like rock to the wellhead in the column drill, a scraper conveyor consisting of two cables 5 with harnes attached to the HIIM is mounted on the scraper 6. At the working position, the scrapers, in a weighted position, abut the back part against the stops. The scrapers 6 reciprocate, the movement towards the wellhead is the working stroke and the movement towards the back side is idle.

During the working stroke, the scrapers clean the breeze from the rock.

The transporter freeze in motion by rotating the handle 7, mounted on

conveyor drum axis.

The rotation of the handle is carried out either manually by two workers, or by a motor with a gearbox.

The forward movement of the core drill to the bottom is carried out by rotation of the spiidel 8, which communicates to the nut 9 connected with the pipe 10 connected directly to the core drill.

The spindle 8 is driven either manually or by a motor.

Subject invention

1. A machine for horizontal drilling of wells under railway and other ground canvases, and with the use of a core drill, inside of which two knives are attached to the bottom-hole part, which have a screw-like surface and are designed to destroy breed and feed it by an amount equal to the length of the idol.
