Embodiment Construction

[0020] According to FIG. 1 , in underground mining, on a mobile drilling machine 1 with a rotating and impact-driven, water-washed long drill bit 2 , an easily assembled working cylinder 3 is provided on one side of the device. The feed support device is formed as a support device resting on the ground 4 and at the same time exerts a controllable feed force acting in the direction of the tool on the drill head 2 . The working cylinder 3 whose rear end is inclined downward is operated and controlled by the hands of the user 5 . Water is supplied to the working cylinder 3 via a pressure hose 6 and to the drill bit 2 via the drilling machine 1 .

[0021] According to FIGS. 2 and 3 , the feed support device consists of a hydraulically driven working cylinder 3 acting on both sides, which has at a first end a mounting device 7 which can be easily mounted on the drilling machine and at the A second end has a foot 8 . The working cylinder 3 is continuously controlled via a manually...

Abstract

The present invention relates to a feed support device for the portable tool device 1 performing at least rotary movement and / or shock movement whihc is formed as a liquid-operated cylinder 3 having a connection means 7 connectable with the tool device 1 in one end part and a support leg part 8 in the other end part. The liquid-operated cylinder 3 can be always controlled by a control valve 10 operated by an operation part 9 capable of adjusting rotation manually. The operation part 9 is constituted as a grip which protrudes in the direction of right angle for an axial line A of the liquid-operated cylinder and whose rotation can be adjusted around an axial line B of the grip. The grip 9 includes whole control region of the control valve 10 in a scope of angle of 180 degrees so as to control it.

Description

technical field [0001] The present invention relates to a mobile drilling machine for at least partial rotation and percussion, especially for blasthole drilling in underground mining. Background technique [0002] This hydraulic, pneumatic or electric mobile drilling machine with a weight of about 15 kg is generally anti-rotating and axially limited to move by a long drill rod washed with water and a circular drill bit with a diameter of about 35 mm of hard material. connect. [0003] According to DE 74 833, a mobile electric rock drill for blasthole drilling in underground mining has a water-washed long drill rod with a hard material round drill bit and a support device. The feed is applied hydraulically through a telescoping drill rod acting as a working cylinder. [0004] According to US Pat. No. 4,000,873, a mobile drilling machine can be supported on one side of the machine relative to the ground by means of an easily mountable feed support and at the same time exert...
