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.

Claims (6)

1. A telescopic feed beam for a rock drill, the feed beam comprising a lower beam (2) intended to be coupled to a boom of a rock drilling apparatus, and an upper beam (1) mounted slidingly in its longitudinal direction relative to the lower beam (2), and a feed extension cylinder (6) coupled to act between the upper beam (1) and the lower beam (2) for moving the upper beam (1) relative to the lower beam (2), a feed cylinder (11) for moving the rock drill (9) relative to the upper beam (1), a flexible transfer element, such as a chain or a wire, mounted to be driven by the feed cylinder (11) and coupled to the upper beam (1) and to the rock drill (9), respectively, or a carriage (10) thereof, such that the rock drill (9) moves a double travel length with respect to the travel length of the feed cylinder (11) or its rod (11a), whereby cylinder spaces (6b, 11b) in the feed extension cylinder (6) and the feed cylinder (11), whereto hy-draulic fluid is fed via a feed conduit (17) during a feed movement of the rock drill (9), are interconnected in parallel relative to the feed conduit (17), characterized in that the pressure surface of a piston (11b) in said cyl-inder space (11c) of the feed cylinder (11) is twice as large as the pressure surface of a piston (6b) in said cylinder space (6c) of the feed extension cylin-der (6), that the feed conduit (17) via which hydraulic fluid is fed to said cylin-der spaces (6c, 11c) during a feed movement of the rock drill (9) comprises a flow indicator (19) for measuring the volume flow rate of the hydraulic fluid fed into said cylinder spaces (6c, 11c) and/or discharged therefrom, and thereby the travel length of the rock drill.
2. A feed beam as claimed in claim 1, characterized in that second cylinder spaces (6d, 11d) of the feed cylinder (11) and the feed exten-sion cylinder (6) of the rock drill are interconnected in parallel relative to a re-turn conduit (18) for hydraulic fluid.
3. A feed beam as claimed in claim 2, characterized in that in a conduit leading from the second cylinder space (11d) of the feed cylinder (11) to the return conduit (18) is provided a pressure limit switch or valve (20), which enables hydraulic fluid flow from said cylinder space (11d) to the return conduit (18) only when the pressure of the hydraulic fluid in the cylinder space (11d) exceeds a preset pressure value, and that the second cylinder space (6d) of the feed extension cylinder (6) is coupled to the return conduit (18) without a pressure limit switch or valve.
4. A feed beam as claimed in claim 3, characterized in that parallel to the pressure limit switch or valve (20) is coupled a non-return valve (21) enabling a hydraulic fluid flow from the return conduit (18) to said cylinder space (11d) of the feed cylinder (11) past the pressure limit switch (20).
5. A method of measuring the travel length of a rock drill during the use of such a telescopic feed beam for a rock drill, the feed beam comprising a lower beam (2) intended to be coupled to a boom of a rock drilling apparatus, and an upper beam (1) mounted slidingly in its longitudinal direction relative to the lower beam (2), and a feed extension cylinder (6) coupled to act between the upper beam (1) and the lower beam (2) for moving the upper beam (1) relative to the lower beam (2), a feed cylinder (11) for moving the rock drill (9) relative to the upper beam (1), a flexible transfer element, such as a chain or a wire, mounted to be driven by the feed cylinder (11) and coupled to the upper beam (1) and to the rock drill (9), respectively, or a carriage (10) thereof, such that the rock drill (9) moves a double travel length with respect to the travel length of the feed cylinder (11) or its rod (11a), whereby cylinder spaces (6b, 11b) in the feed extension cylinder (6) and the feed cylinder (11), whereto hy-draulic fluid is fed via a feed conduit (17) during a feed movement of the rock drill (9), are interconnected in parallel relative to the feed conduit (17), characterized by dimensioning the pressure surface of a piston (11b) in said cylinder space (11c) of the feed cylinder (11) twice as large as the pressure surface of a piston (6b) in said cylinder space (6c) of the feed exten-sion cylinder (6), by measuring the entire volume flow rate of the hydraulic fluid fed into said cylinder spaces (6c, 11c) and/or discharged therefrom, and thereby the travel length of the rock drill.
6. A method as claimed in claim 5, characterized by meas-uring the volume flow rate of the hydraulic fluid by means of a flow indicator (19) mounted in the feed conduit (17), hydraulic fluid being fed to said cylinder spaces (6c, 11c) via said indicator during a feed movement of the rock drill (9).
