Abstract
Description
- The present invention relates to a method and a device for providing oscillation damping in a hydraulically operated crane. In particular, the invention relates to a crane having a loading tool attached to a swingable jib.
- Such cranes are generally occurring, for example, in the forestry business for the loading of timber. It is in that connection, a generally familiar fact that it is difficult for the operator to bring the loading tool quickly and securely into an exact position for engagement with the cargo to be lifted.
- This problem is obviated or at least brought down to a minimum by means of the present invention.
- In the method according to the invention, the hydraulic regulation of the jib embraces an operator-independent pressure detection provided for a rotator link belonging to the working tool and intended for the counteraction of undesired oscillations of the loading tool.
- The pressure detection is advantageously effected on a hydraulic swing device arranged for the swingable jib and produces pressure information that is fed into a break means that, in the rotator link between the loading tool and the outer end of the jib, damps the oscillatory motion of the loading tool.
- Preferably, the oscillation damping is effected by the break means acting against at least one joint of the rotator link.
- By a device according to the invention, a rotator link belonging to the loading tool has a hydraulically actuated brake mechanism, the regulation of which is operator-independently pressure sensed for the counteraction of undesired oscillations of the loading tool.
- Preferably, the brake mechanism is formed with a hydraulically actuated brake, which, via a line, is coupled to a hydraulic swing device arranged for the swingable jib for the receipt of pressure information.
- The rotator link is preferably double jointed and at least one of the joints thereof is formed with the hydraulically actuated brake mechanism.
- The brake mechanism advantageously embraces a piston/cylinder device where the cylinder is coupled to one joint of the rotator link, the one joined to the loading tool. The piston rod projecting into the cylinder is coupled to the other joint of the rotator link, the one joined to the jib of the crane.
- The pressure detection is preferably effected on a hydraulic swing device - arranged for the turning of the swingable jib - for the receipt of pressure information from the same.
- This pressure information from the hydraulic swing device arranged for the swinging of the jib is conveyed to the chamber in the cylinder of the break means via an axially extending channel in the piston rod projecting into the cylinder.
- The pressure information is extracted from the hydraulic swing device, drive motor, of the jib in the hydraulic chamber of which pressure variations are produced upon the swinging of the jib. A pressure detecting system is coupled to the hydraulic chamber of the drive motor for the transfer of the pressure information to the piston/cylinder device of the break means in the rotator link of the loading tool.
- Advantageously, the pressure-sensing system embraces a reverse valve connected to the hydraulic chamber of the drive motor in order to, via a pressure-indicating line, forward the occurring pressure present during the swinging of the jib to the cylinder in the break means of the loading tool. The reverse valve allows braking upon both acceleration and retardation of the swing motion of the jib.
- The invention furthermore relates to a crane that comprises a device for damping oscillations in accordance with what has been mentioned above.
- The invention will be explained more in detail below in connection with an embodiment that shown in the appended drawings and depicted in connection with a known crane for forestry use, wherein
-
Fig. 1 shows a view from the side of the crane and -
Fig. 2 shows the principle for the oscillation damping according to the invention. - The oscillation damping according to the present invention, which is operator-independent, automatic and self-locking, will be exemplified in an application of a crane 1 known per se, as shown in
Fig. 1 . This crane 1 has ajib 2 that comprises different, hydraulically driven regulating parts irrelevant to the present invention. Thejib 2 is fixedly anchored on a support, for example on a lorry/truck chassis (not shown), by means of a hydraulically drivenswing device 6. At thefree end 5 of thejib 2, there is suspended a loading tool in the form of a grip 3. Thejib 2 is swingable in the horizontal plane around the vertical axis 7 of theswing device 6. This swinging is operated by means of the hydraulically drivenswing device 6. - In the operation of the
jib 2, theswing device 6 is thus brought to swing the same for adjustment into a position where the cargo to be lifted is placed. A certain technique is required of the operator conducting the crane in order to get the grip 3 into the correct position. Even if it is known to form therotator 4 with a brake mechanism having oscillation dampers, the grip 3 will still obtain an undesired oscillation. - In order to obviate or at least quickly bring down this undesired oscillation to a minimum, the present invention embraces an operator-independent pressure detection in the hydraulically driven
swing device 6. In that connection, a pressure indication or pressure information is obtained that is fed to an oscillation dampingrotator link 14 belonging to therotator 4. - The principle for the invention will be described in more detail in the following, reference being made to
Fig. 2 . This figure illustrates the invention in connection with aswing device 6 known per se and arotator link 14 known per se. Therefore, it should be entirely clear to the reader that the invention is applicable also in other embodiments of swing devices and oscillation dampers for cranes. - Thus, the crane is equipped with a
hydraulic swing device 6 that can swing the crane jib both clockwise and counter clockwise. The hydraulics of theswing device 6 may be made as any hydraulic drive motor having hydraulic pressure chambers, but in the embodiment described herein, it embraces fouractuator cylinders swing device 6 to a hydraulic source S. In the intermediate position 0, theswing device 6 is locked while the positions L and R feed thecylinders swing device 6 from the hydraulic source S for the swinging of the jib to the left and to the right, respectively. - The
rotator link 14 known per se embraces abrake mechanism rotator link 14 is double jointed 5, 19, where at least one of the joints is actuatable by a brake function. In the embodiment shown here, thebrake mechanism rotator link 14 embraces a piston/cylinder device interconnected between the twojoints piston rod 16 is then joined to thejoint 5 directed perpendicular to the plane of the drawing while thecylinder 18 is coupled to thejoint 19 extending in the plane of the drawing. - For the provision of the operator-independent function counteracting undesired oscillations, the
piston rod 16 according to the invention is provided with achannel 17, which mouths in achamber 20 formed by thecylinder 18. Thechannel 17 is connected to areverse valve 10 via theline 9. By the two entrances thereof, thereverse valve 10 is joined to theswing device 6 for the output of the pressure that prevails in the hydraulics thereof in the swinging of the jib of the crane. Thereverse valve 10 supplies said hydraulic pressure to therotator link 14 and the piston/cylinder device reverse valve 10 allows braking upon both acceleration and retardation of the swing motion of the jib. - When swinging of the jib of the crane is desired, the actuator valve V, which is spring-loaded so as to normally assume the middle position 0, is brought into one of the outer positions, for example into L, for the swinging of the jib to the left. In that connection, the
cylinder 11 B is pressurized from the hydraulic source S, while thecylinder 12B is pressure-relieved. On thecylinder 11 B as well as on thecylinder 12A, a pressure is then obtained (a pressure change, pressure increase, pressure pulse) that, via thereverse valve 10 and theline 9, is supplied to the piston/cylinder device rotator link 14. By the pressure change arisen thereby in thechamber 20 of thecylinder 18, in the embodiment shown herein, the piston/cylinder device respective joint swing device 6 in the right direction. - By the fact that the pressure detection is carried out automatically in the
swing device 6 and is forwarded to therotator link 14 via thereverse valve 10, there is obtained an operator-independent damping oscillation function for the jib of the crane and the working tools thereof. - Even if the invention and the function thereof here has been exemplified in connection with a known embodiment of the
swing device 6 and a known embodiment of therotator link 14, a person skilled in the art appreciates that the invention also is applicable in other embodiments. Accordingly, the swing device may equally well be hydraulic components of another embodiment where pressure detection may take place, and the rotator link may be designed differently with pressure action by, for example, drum brakes or disc brakes. - Therefore, the present invention must not be considered limited to the above-mentioned designs, but its principle, as defined in the subsequent claims, is applicable in different embodiments.
