Send to extending cylinder 6 be arranged on upper boom 1 below, this earthen pipe of sending extending cylinder to is connected in the soffit of this upper boom 1.Preferably, this is sent extending cylinder 6 to and is fixed in this upper boom 1 in mode not removable, that can not rotate rigidly and relative to it.Conversely, this piston rod 6a that sends extending cylinder 6 to is connected in the front end of this lower beam 2 again at the one end.It is passable that this sends extending cylinder 6 to, for example, is connected with bolt in the base plate that is screwed into this upper boom 1 by being fixed in this flange 7 of sending extending cylinder 6 earthen pipes to.Certainly fixing can carrying out with any self other known mode.Fig. 1 also illustrates the rock-boring machine support 10 that is intended to the rock drill 9 that moves along upper boom and slidably installs along the second sliding rail 1b in self known mode, and this second sliding rail 1b is arranged on the top of this upper boom 1.For moving of rock drill 9 and support 10, feed cylinder 11 is set, and idle pulley 12 is connected in the earthen pipe of this feed cylinder in this upper boom.The feed wire 13 that is connected in upper boom 1 and rock-boring machine support 10 is passed through around idle pulley 12 again.Normally self is known for such feed cylinder/structure of steel wire, therefore is not described in detail here.By sending the working medium in the feed cylinder 11 to, its piston rod 11a is pushed (expelled), and earthen pipe moves to the front end of upper boom, thereby push away this feed wire by idle pulley to its front, so rock drill 9 and support 10 continue to move with the speed with piston rod 11a and idle pulley 12 twices respectively.Accordingly, when the piston-retraction of this feed cylinder, this rock drill moves to the rear portion of upper boom 1 in self known mode.Accompanying drawing also is illustrated in the drilling rod stroke centralizer 14 of upper boom 1 front end and at the preceding centralizer 15 of lower beam 2 front ends.This centralizer self known fully, and is not essential part of the present invention, therefore they is not described in detail.
Fig. 2 is the sectional view of the feed beam structure of Fig. 1 along the A-A line of Fig. 1.Fig. 2 illustrates lower beam 2 and how is made of vertical sides f 2a and the transverse bottom plate 2b that is arranged between the sidepiece.The space 2c of chute-like is formed between sidepiece and the base plate, sends extending cylinder 6 to and be arranged on below the upper boom 1 in this space.This top of sending the earthen pipe of extending cylinder 6 to has holding flange 7, and this flange 7 is fixed with respect to this upper boom 1 these two ends of sending extending cylinder 6 in immovable mode.By this way, this sends extending cylinder 6 to and its piston rod 6a is always protected in all time between upper boom 1 and lower beam 2.The section bar 3 that has carriage 16 in its inside is connected on the rim lip 2d that is arranged on lower beam 2 lateral edge by bolt 5.This carriage (slides) 16 contacts with the slidingsurface 4 of the sliding rail 1a of upper boom 1 again, makes upper boom slide in the tight mode that contacts mutually with lower beam.
Fig. 3 is the schematic diagram that is used to realize that suitable hydraulic pressure of the present invention connects.Fig. 3 schematically illustrates upper boom 1 and lower beam 2, and they can vertically relatively move mutually along it.Send extending cylinder 6 usefulness flanges 7 grades to and be connected in upper boom 1, make this send extending cylinder 6 to and vertically can not move along it with respect to this upper boom 1, its piston rod 6a in its end to be connected to lower beam 2 along its vertical immovable mode.Correspondingly, the piston rod 11a of feed cylinder 11 is to be connected in upper boom 1 along its vertical immovable mode.Hydraulic fluid supply pipe 17 and recurrent canal 18 are connected in by this way sends extending cylinder and feed cylinder to, makes their cylinder space 6c and 11c, and 6d and 11d are respectively parallel respectively with respect to pipe 17 and 18.During feed motion, during boring, the supply pipe 17 that supplies in this cylinder along this pipe hydraulic fluid has flow indicator 19, it can be complete indicator or only be the sensor that sends with the proportional signal of flow rate, more preferably, can measure along the flow rate of the hydraulic fluid of both direction.Pipe 17 also is connected in the cylinder space 6c on the side of the piston rod 6a that sends extending cylinder piston 6b to, and accordingly, is connected in the cylinder space 11c relevant with the piston rod 11d of feed cylinder 11.Return move during, this recurrent canal 18 that is used to supply with hydraulic fluid is connected in this again and sends second cylinder space 6d of extending cylinder 6 and the second hydraulic fluid space 11d of this feed cylinder 11 to.During feed motion, when hydraulic fluid is supplied to pipe 17, hydraulic fluid is discharged from cylinder space 6d and 11d via this pipe 18, and correspondingly, during return movement, when hydraulic fluid was supplied to pipe 18, hydraulic fluid was discharged from cylinder space 6c and 11c by flow indicator 19 via pipe 17.
Except idle pulley 12, Fig. 3 also illustrates the second idle pulley 12a that is positioned at these feed cylinder 11 1 ends.Such as the flexible transmission parts of steel wire or chain 13 around feed wheel 12 and 12a by and be connected in upper boom 1 with securing member 13a, and correspondingly, be connected in the support 10 of rock drill with securing member 13b, perhaps, alternatively, be directly connected in rock drill 9 in self known mode.When feed cylinder 11 moves with respect to upper boom 1, it promotes chain or steel wire 13 towards its front, and by the effect of closed hoop, securing member 13a moves double distance with respect to the haul distance of cylinder 11 along same direction, and rock drill moves same distance.
The size of sending extending cylinder 6 and feed cylinder 11 to is made and is made that towards the pressure surface of the piston 11b of the cylinder space 11c of feed cylinder 11 be twice towards the pressure surface of the piston 6b of the cylinder space 6c that sends extending cylinder 6 to.The given unit volume of sending the hydraulic fluid among this cylinder space 6c that sends extending cylinder 6 to makes upper boom 1 move given distance with respect to lower beam 2.Correspondingly, the hydraulic fluid of sending the same amount among the cylinder space 11c of feed cylinder 11 to makes this feed cylinder 11 move half of this distance with respect to upper bracket 10.Because the motion that provides for rock drill 9 of feed cylinder 11 is the twice of himself haul distance, consequently, the hydraulic fluid of this given unit volume, rock drill 9 is equaled with respect to the distance that upper boom 1 moves, owing to send the effect of the amount of this hydraulic fluid of sending extending cylinder 6 to, the distance that this upper boom moves with respect to lower beam.Because this result, no matter the hydraulic fluid of specified rate is two cylinders that flow to that hydraulic fluid only flows to a cylinder or part always corresponding to the given haul distance along the feeding direction rock drill.The flow rate of the hydraulic fluid of discharging via hydraulic fluid pipe 18 from cylinder space 11d and 6d can be obviously different mutually, but the situation between this cylinder space 6c and the 11c is not influenced.By this way.Only can be used in the amount of measuring the hydraulic fluid that is used for feed motion simple and reliablely, therefore, measure the length of the feed motion of this rock drill simple and reliablely with an indicator.
Under situation shown in Figure 3, when rock drill when opposite direction moves in the mode of return movement, because hydraulic fluid is with respect to piston 11b this feed cylinder 11 that moves right, this rock drill moves along upper boom 1 on the one hand, thereby total length of this feed cylinder 11 and its piston rod 11a shorten.Correspondingly, send extending cylinder 6 to and make their total length increase because hydraulic fluid promotes this with respect to its piston 6b, this upper boom 1 outwards moves from it with respect to lower beam 2, makes the total length of this feed beam increase.In this case, hydraulic fluid flows in opposite direction by indicator 19 and flows out by pipe 17 from cylinder space 6c and 11c.Even if in this case, rock drill is directly proportional with the volume flow rate of the hydraulic fluid that flows through this flow indicator 19 with respect to the haul distance of lower beam 2 along Return-ing direction, therefore, the length of this rock drill return movement is also measured reliably by measuring this flow rate.By this way, be selected to by the piston pressure surface of sending extending cylinder 6 and feed cylinder 11 to feed mechanism that to make its ratio be 1 to 2 ratio substantially, this rock drill only promptly can be measured with an indicator reliably along the whole haul distance of both direction.
Fig. 4 schematically illustrates according to a preferred embodiment of the invention.Except having preferred supplementary features, its operation and structure are similar to embodiment shown in Figure 3, and by these preferred supplementary features, the motion of this upper boom 1 and lower beam 2 and the motion of this rock drill can be with desirable order controls.With regard to the function of boring and the quality of boring, advantageously, short at first as far as possible ground relatively moves this feed beams mutually, and has only and begin after this to move this rock drill along upper boom 1.In this embodiment, pressure limit switch or limiting valve 20 are connected in the pipe of guiding service time (feed-time) recurrent canal 18 into from the cylinder space 11d of feed cylinder 11.The operation of pressure limit switch or limiting valve 20 is such, and during feed motion, the counter-pressure that trends towards the hydraulic fluid of discharging from cylinder space 11d is higher than the counter-pressure of the cylinder space 6d that sends extending cylinder 6 to that is directly connected in pipe 18.In this situation, the hydraulic fluid that is supplied to is more prone to enter sends extending cylinder 6 to, therefore push away this upper boom 1 with respect to lower beam 2.When upper boom when its whole length moves, upper boom mobile stops and also stopping from the hydraulic fluid of cylinder space 6d.As a result, the pressure of the hydraulic fluid among pipe 17 and the cylinder space 11c, and the pressure of the hydraulic fluid among the 11d of cylinder space raise, the limits value of setting in its overpressure limit switch 20.This hydraulic fluid begins to flow to pipe 18 via pressure limit switch 20 then, and further flows out, thereby rock drill moves with respect to upper boom 1 in mode described above.
Fig. 4 also illustrates one way valve 21, flows through this pressure limit switch 20 by this valve hydraulic fluid and flow to cylinder space 11d during return movement.In this situation, who is at first mobile not need to select them usually, because it is to not influence of boring result.Certainly, when needs determined which moving movement at first takes place, this pressure limit switch can mode shown in Figure 4 be connected in opposite direction, from pipe 18 to feed cylinder 11 or to sending extending cylinder 6 to.
In superincumbent description and the accompanying drawing, only invention has been described by way of example, it is limitation of the present invention anything but, the feed mechanism of this rock drill can be not only feed cylinder/structure of steel wire, though feed cylinder/structure of steel wire in use is favourable, also can be some other feed cylinder mechanism.
