Mechanism for impact drilling machine with improved rocker pulley action

Impact mechanism (100) raises and drops the free end of a lifting rope at set intervals, driving an underground impact boring tool. The new mechanism is a rocker (4) pivoting about an axis (A) perpendicular to the rope. One either side of this axis, pulley axes (S,S') are set parallel, the impact rope being passed through the pulleys. To cause impact, a drive pivots the rocker cyclically between resting- and releasing positions. In the latter, the rope wraps more of the pulley circumferences than at rest. Also claimed is an impact drilling machine with the mechanism as described, on the free end of the impact rope, opposite the side of the drilling mast (2), or at its head. The lifting rope (5) also serves as the impact rope.

The present invention relates to a hydraulic control device of the rock drilling machine for drilling rock. 그러나, 종래의 유압식 암반천공기에서는, 천공 시작시의 작업이나, 암반에서 균열이나 공동이 있는 장소를 천공하는 때에, 가변 용량형 유압 펌프로부터 송출된 압력유의 일부가 릴리프 밸브로부터 탱크에 되돌려지는 때에 압력유의 에너지가 열로 변환되어서 쓸데없이 소비될 뿐만 아니라, 작동유가 열화되고 발열된 작동유의 냉각이 필요하게 되어 바람직하지 않다. 또한, 시시각각 상태가 변화되는 암반을 천공하는 경우에 단계적인 제어로는 능률 좋게 정확한 천공을 하는 것이 곤란하다는 문제를 가지고 있었다. However, in the conventional hydraulic rock drilling machine, when a part of the pressure oil sent from the variable displacement hydraulic pump is returned from the relief valve to the tank when drilling at the beginning of the drilling or when drilling the place where there are cracks or cavities in the rock, Not only is the energy converted to heat and consumed unnecessarily, but also the oil is degraded and cooling of the exothermic oil is required, which is undesirable. In addition, in the case of drilling a rock whose state changes from time to time, there was a problem that it was difficult to efficiently and accurately drill with a stepwise control. 본 고안은 이러한 상기의 문제를 해결하기 위한 유압식 암반천공기의 제어장치를 제공함에 그 목적이 있다. The present invention has an object to provide a control device of a hydraulic rock drilling machine for solving the above problems. 본 고안의 유압식 암반천공기는, 가변 용량형 유압펌프(11)의 송출 관로(18)가 조작밸브(10)를 거쳐서 유압식 암반천공기(1)의 구동 관로(20)에 접속됨과 동시에, 조작 밸브(10)을 거쳐서 유압식 암반천공기(1)의 구동 관로(20)에 접속되며, 가변 용량형 유압펌프(11)의 서보기구(21)에는, 유압식 암반천공기(1)의 구동 관로(20)로부터 분기하여 유압신호 관로(22)가 접속되고, 이 유압신호 관로(22)에는, 감압밸브(12)와 신호압력 조작밸브(13)가 설치되어 있으며, 감압밸브(12)는 유압신호 관로(22)의 최고 압력을 규제하고, 신호압력 조작밸브(13)는 수동 조작의 가변 감압밸브이며, 수동핸들의 조작량에 의하여 유압신호 관로(22)의 신호 압력을 무단계로 변화시켜서 서보기구(21)를 통하여 가변용량형 유압펌프(11)의 송출량을 무단계로 제어하도록 하고, 편솔레노이드 4/2웨이 방향제어밸브(30)를 구동관로(20)에 설치하여 편솔레이드에 전류가 흐를 때는 편솔레노이드 4/2웨이 방향제어밸브(30)의 작동위치에 놓이게 되어 상기의 신호압력 조작밸브(13)로 압력유가 들어가지 않고, 릴리프밸브(31)를 통하여 탱크로 유출시키도록 하여서 서보기구가 작동되지 않도록 하며, 편솔레이드에 전류가 흐르지 않도록 하면, 편솔레노이드 4/2웨이 방향제어밸브(30)의 정상위치에 놓이게 되어 다시 감압밸브(12)를 통하여 신호압력 조작밸브(13)를 흐르는 압력유가 ...

PROCEDURE FOR THE GOVERNMENT OF THE CABLE DRUM OF A LATHE, FOR A WEIGHT OF MARTINETE HANGING ON THE CABLE AND FALLING FREE.

The invention relates to a control system with which the rope (3), drawn off from a cable drum (4) by a ramming weight (5), can be braked essentially without shocks within a predetermined overrun travel while avoiding a slack rope formation and while maintaining the selected drop height during subsequent blows, the winch drum being driven with adjustable torque by a motor (12) via a slip clutch. The torque when lifting over the height of the overrun travel is set to a threshold value which is matched to the weight of the rope and the load suspension device in such a way that the latter, but not the ramming weight (5), is lifted. After the threshold value is reached, the tensile force of the rope activates a measuring device (15) before or during the lifting of the ramming weight, which measuring device (15) measures the sectional length up to the desired drop height. When the threshold value is reached, the clutch is switched from the lower torque of the overrun travel to the torque for lifting the ramming weight or to the rated torque. The clutch is switched to free running after a rope length corresponding to the drop height is wound onto the winch, and the winch brake is engaged as soon as a rope length corresponding to the drop height has run off the winch drum. <IMAGE>
