Embodiment Construction

[0012] figure 1 A telescoping feed rod comprising an upper rod 1 and a lower rod 2 is shown. The upper bar 1 and the lower bar 2 are mutually slidably installed along the longitudinal direction thereof by means of a slide rail 1a under the upper bar 1 and a slider 3 connected to the lower bar 2 . The upper rod 1 is manufactured from, for example, an aluminum alloy by extrusion, and its sliding surface is preferably formed at the same time. The sliding track has a sliding surface 4 for the slider, which is usually a steel band in an aluminum rod or the like. And this sliding part 3 is most preferably made of aluminum profile again, and sliding device (slides) is with figure 2 Attached to the slider 3 in the manner shown, the slider is in contact with the sliding surface 4 . The slider 3 is connected to the lower rod 2 with a bolt 5 . At the front end of the lower bar 2, preferably the slider extends substantially over the entire length of the upper bar 1, the sliding means...

Abstract

The invention relates to a telescopic feed beam for a rock drill and to a method of measuring a travel length. The pressure surface of a piston (11b) in a feed cylinder (11) of the feed beam is twice as large as the pressure surface of a piston (6b) in a feed extension cylinder (6). Furthermore, the feed beam comprises a flow indicator (19) for measuring the volume flow rate of hydraulic fluid fed and / or discharged, and thereby the travel length.

Description

technical field [0001] The present invention relates to a telescopic feed rod for a rock drilling machine, comprising a lower rod intended to be connected to a boom of rock drilling equipment, and an upper rod mounted slidably relative to the lower rod along its longitudinal direction, and connected to the an upper rod and a lower rod and acting therebetween a feed extension cylinder for moving the upper rod relative to the lower rod, a feed cylinder for moving the rock drilling machine relative to the upper rod, such as a chain or A flexible transmission element of a wire rope mounted to be driven by the feed cylinder and connected to the upper rod and the rock drilling machine or its support respectively such that the rock drilling machine is relative to the feed cylinder or its rod The stroke length of is shifted double the stroke length, so the feed extension cylinder and the cylinder space in the feed cylinder to which hydraulic fluid is fed via the feed conduit during th...
