Abstract

DRILLING MACHINE - including your drive motor connected to the spindle through a planetary gearbox, driven by a brake motor with a low-pressure motor consisting of a reversing motor, a pressure pipe and a drain line, that is, In order to increase the reliability of the device by damping the vibration, the brake mechanism is designed as a hydraulic machine with adjustable performance of batteries, throttles, reversible and safety valves, each working cavity is hydraulic. The roshin is hydraulically connected through a choke to the accumulator, through a check valve with a pressure head valve and through a safety valve with a drain line. WITH

Description

The invention relates to the mining industry, and in particular to rotators of drilling rigs.

• Known rotator of a drilling rig, including · a drive motor connected to the spindle through a planetary gear [1]. "

However, this rotator does not provide damping of vibrations and is not protected from overloads.

Closest to the proposed is the rotator of the drill head, including a drive motor [2].

However, the known rotator does not provide vibration damping, which reduces its reliability.

The purpose of the invention is to increase the reliability of the device by damping vibration.

This goal is achieved by the fact that the brake mechanism is made in the form of a hydraulic machine with adjustable capacity of accumulators, throttles, check * and safety valves, and each working cavity of the hydraulic machine is hydraulically connected through a throttle to the battery, through a check valve with a pressure line and through a safety valve with drain line.

The drawing shows a diagram of the proposed device.

The rotator contains a drive motor 1, connected to spindle 2 through a planetary gearbox consisting of epicycles 3 and 4, carrier 5 and gear 6 rigidly mounted on spindle 2, carrier 5 is connected with a brake mechanism consisting of a reversible hydraulic machine, 7 adjustable. manufacturer ”whose working cavities 10 are hydraulically connected through chokes 8 and 9 with accumulators 10 and 11, through check valves 12 and 13 with a pressure line 14 and through safety valves 15 and 16 15 with a drain line 17.

The rotator operates as follows.

Rotation from the motor 1 through the gearbox is transmitted to the spindle 2. 2Q Batteries 10 and 11 dampen the vibration, allowing the rotation of the shaft of the hydraulic machine 7. When locking (slamming). at the drill head, safety valves 15 or 16 and 25 of the hydraulic machine shaft 7 are connected, connected to the spindle through a planetary gear, the carrier of which is connected to a brake mechanism consisting of a reversing motor, pressure and drain lines.

The hydraulic system is fed from the pressure line 17.

Vibration damping increases the reliability of the device. ··
