Definitions

  • the present invention relates to a hydraulic ram for an excavator coupler for coupling an attachment, such as an excavating bucket, to the arm of an excavator.
  • an excavator coupler to have at least one hydraulically operated latching hook for engaging with a rear pin of an attachment, e.g. a bucket, to secure the attachment to the arm of an excavator, the latching hook being movable into and out of a latching state under the action of a hydraulic ram.
  • a major problem with existing couplers is that operator misuse or incorrect operation of the coupler can cause the attachment to swing or even completely detach from the coupler posing a safety hazard. When an operator uses a coupler to lift an attachment he cannot always determine that the latching hook has engaged with the rear pin of the attachment correctly. This can lead to the attachment swinging on a single pin with danger to personnel and possible damage to plant and equipment.
  • a first aspect of the present invention provides a hydraulic ram for an excavator coupler comprising a cylinder having a head end adapted to be connected to one of the body of the excavator coupler and a latching hook thereof, a piston slidably mounted in the cylinder between a retracted position adjacent the head end of the cylinder and an extended position adjacent a distal end of the cylinder, opposite said head end, said piston dividing the cylinder into a first working chamber adjacent said head end of the cylinder and a second working chamber adjacent said distal end of the cylinder, a piston rod extending from the piston through said second working chamber of the cylinder to extend out of the distal end of the cylinder, a distal end of the piston rod being adapted to be connected to the other of the body of the excavator coupler and said latching hook thereof, a first fluid supply port being provided for supplying pressurised fluid into said first working chamber to urge the piston and piston rod away from said head end of the cylinder towards said extended position, where
  • said signal port is arranged to be obscured by said piston, preventing communication between said signal port and the first working chamber of the cylinder, when the piston is in a partly extended position.
  • the length of the ram is selected such that the piston is in said partly extended position when a latching hook of an excavator coupler to which the ram is fitted is in engagement with a rear pin of an attachment, such that the signal port is isolated from the first working chamber of the cylinder, preferably by being obscured by the piston, when the latching hook is engaged with the rear pin of an attachment.
  • the piston is able to move to its fully extended position, exposing the signal port whereby pressurised fluid from the first working chamber passes into said signal port.
  • suitable sensing means such as a pressure or flow sensor, for example by detecting a pressure drop in said first working chamber, providing an indication that the latching hook is not in correct engagement with the rear pin of the attachment.
  • Said hydraulic ram may comprise a double acting ram, a second fluid supply port being provided for supplying pressurised fluid into said second working chamber of the cylinder for moving the piston towards its retracted position.
  • Said signal port may be arranged to communicate with a fluid line communicating with said second fluid supply port.
  • a check valve may be associated with said signal port preventing the passage of pressurised fluid from said fluid line to said signal port.
  • a coupler for an excavator comprising a body having a spaced-apart recesses for receiving respective attachment pins of an excavator attachment; a latching member being associated with at least one of said recesses, said latching member being movable into and out of a latching state in which it is capable of retaining one of said attachment pins of said excavator attachment in said recess; a hydraulic ram being provided for moving said latching member into said latching state; said hydraulic ram comprising a cylinder having a head end connected, either directly or indirectly, to one of the body of the coupler and the latching member, a piston slidably mounted in the cylinder between a retracted position adjacent the head end of the cylinder and an extended position adjacent a distal end of the cylinder, opposite said head end, said piston dividing the cylinder into a first working chamber adjacent said head end of the cylinder and a second working chamber adjacent said distal end of the
  • the flow of oil through the signal port may be detected by any suitable means, such as a pressure sensor of flow meter.
  • the spaced-apart recesses of the coupler may comprise a front recess adapted to receive a front pin of an attachment, and a rear recess, adapted to receive a rear pin of an attachment, said latch member being associated with said rear recess such that the latching member engages the rear pin of the attachment when the latching member is in its latched state and the rear pin is located in the rear recess.
  • said front recess comprises an opening facing away from said rear recess such that said front pin is retained within said front recess when the rear pin is engaged within said rear recess.
  • said signal port is arranged to be obscured by said piston, preventing communication between said signal port and the first working chamber of the cylinder, when the piston is said partly extended position.
  • the hydraulic ram comprises a double acting ram, a second fluid port being provided for supplying pressurised fluid from a second fluid line into said second working chamber of the cylinder for moving the piston towards its retracted position to move the latching member out of its latching state.
  • Said signal port may be arranged to communicate with said second fluid port.
  • a check valve may be associated with said signal port preventing the passage of pressurised from said second fluid port to said signal port while permitting fluid to flow from said signal port to said second fluid port.
  • This invention relates to an improved hydraulic coupler employing a modified hydraulic ram within the coupler which provides an indication when the piston rod of the ram is fully out-stroked (fully extended). This fully out-stroked condition can only occur when a latching hook of the coupler has missed the rear pin of the attachment so the indication can be used to warn the operator that the rear pin is not engaged. Because of the environment in which the coupler works wires to the coupler and electrical and electronic sensors within the coupler can prove unreliable and troublesome. However hydraulic oil is fed to the hydraulic ram of the coupler via hydraulic hoses. The ram is designed so that it will pass a limited amount of oil continuously at full stroke and this can be detected remotely from the coupler.
  • a latching hook 12 is pivotally mounted on the body 2 to be moveable into and out of a latching state, wherein the latching hook 12 engages the rear pin 10 of the attachment to retain the pin 10 in the rear recess 8.
  • the latching hook 12 may be linearly slidable or otherwise displaceable into and out of its latching state.
  • the latching hook 12 is moveable into and out of its latching state by means of a double acting hydraulic ram 14.
  • the ram 14 comprises a cylinder 16 having a closed head end 18 mounted on the body 2 of the coupler.
  • a piston 20 is slidably mounted within the cylinder along the longitudinal axis of the cylinder 16 between a retracted position, adjacent the head end 18 of the cylinder 16, and an extended position adjacent a distal end 22 of the cylinder, opposite said head end 18.
  • the piston 20 divides the cylinder 16 into first and second working chambers 24,26.
  • a piston rod 28 extends from the piston 20 through the second working chamber 26 and out of the distal end 22 of the cylinder 16, a distal end of the piston rod 28 being connected to the latching hook 12.
  • the hydraulic ram 14 is fed with pressurised hydraulic fluid from either the excavator main hydraulic line or the excavator servo (reduced pressure) hydraulic line.
  • pressurised hydraulic fluid from either the excavator main hydraulic line or the excavator servo (reduced pressure) hydraulic line.
  • From a valve mounted normally within the engine/hydraulic compartment of the machine two high pressure hydraulic pipes either flexible or a mixture of flexible and rigid run from the engine compartment, up the excavator boom, unsupported across the excavator boom to dipper connection, down the dipper arm, unsupported across the excavator dipper to hitch, and terminate at the hydraulic ram 14 within the coupler body 2.
  • the first and second working chambers 24,26 of the ram 14 are selectively fed with pressurised hydraulic fluid to selectively extend and retract the piston rod 28.
  • a first fluid line communicates with the first working chamber 24 via a first fluid port A in the side wall of the cylinder adjacent the head end thereof to supply pressurised fluid to the first working chamber 24 to move the piston 20 towards its extended position, extending the piston rod 28 from the cylinder 16 and moving the latching hook 12 towards into its latched state.
  • a second fluid line communicates with the second working chamber 26 via a second fluid port B in the wall of the cylinder 16 adjacent the distal end 22 thereof to supply pressurised fluid to the second working chamber 26 to move the piston 20 towards its retracted position, retracting the piston rod 28 into the cylinder 16 and moving the latching hook 12 out of its latched state.
  • a signal line communicates with a signal port Bs provided in the wall of the cylinder 16 adjacent the second fluid port B, spaced from the distal end of the cylinder 16.
  • the signal line feeds into the second fluid line, thus the signal port Bs is in fluid communication with the second fluid port B.
  • the signal port Bs is position in the wall of the cylinder 16 to be uncovered by the piston 20 when the piston 20 is caused to travel past the signal port position to a fully extended or out-stroked position by the application of pressure to the first working chamber 24 via the first fluid port A.
  • the uncovering of the signal port Bs will allow fluid from the high pressure side of the piston (i.e. the first working chamber 24) to enter the signal port Bs. This will cause fluid to circulate from the first fluid line to the second fluid line when the piston 20 moves past the signal port Bs as the piston reaches is fully extended position. This circulation of oil can then be detected and used as an indication of excessive piston travel.
  • the signal port Bs and/or its associated fluid line has a much smaller diameter than either of the first or second ports A, B and associated first and second fluid lines, limiting the amount of oil that it can pass. Because the amount of oil escaping is small compared to the volume of oil supplied to the cylinder, the escape of oil will have little influence on the overall action of the ram 14.
  • the front pin 6 of an attachment is manoeuvred into the front recess 4 of the coupler.
  • the coupler is then manipulated to swing the rear pin 10 into the rear recess 8.
  • Pressurised fluid is supplied to the first port A of the cylinder 16 and enters the first working chamber 24 of the cylinder 16. This causes the piston 20 to move to the right (as illustrated in Figures 4 to 6 ) and the piston rod 28 to be extended from the cylinder 16, moving the latching hook 12 towards its latching state. Fluid from the second working chamber 26 of the cylinder 16 will leave the cylinder via ports Bs and B.
  • the piston 20 is arrested in a partly extended position, as illustrated in Figures 1 and 4 . In such position, the piston 20 obscures the signal port Bs, isolating the signal port Bs from the first working chamber of the cylinder 16.
  • FIGs 2 and 5 illustrate the situation should the latching hook 12 failed to correctly engage the rear pin 10 of the attachment.
  • the latching hook 12 fails to engage the rear pin 10 and the piston 20 of the ram 14 is able to move to its fully extended position adjacent the distal end 22 of the cylinder 16, fully extending the piston rod 28.
  • the piston 20 has moved to the extreme right hand distal end of the cylinder 16, the piston 20 has uncovered signal port Bs such that the signal port Bs communicates with the first working chamber 24 of the cylinder 26. This means fluid entering the first working chamber 24 of the cylinder 16 through port A will also be able to drain through port Bs as indicated by arrow X and into the second fluid line.
  • the flow of fluid through the signal port Bs can be detected by suitable means, such as a pressure sensor or flow sensor, to provide an indication to the operator that the attachment is not correctly coupled to the arm.
  • the size of the signal port Bs and its associated signal line is substantially smaller than the size of the second port B and the second fluid line.
  • Figures 3 and 6 illustrate the situation wherein the coupler is attached to an attachment having a reduced pin spacing.
  • the latching hook 12 engages the rear pin 10 of the attachment earlier, such that the extension of the piston rod 28 from the cylinder 16 is less before the latching hook 12, and thus further extension of the ram, is arrested by engagement of the latching hook 12 with the rear pin 10 of the attachment.
  • the signal port Bs may be provided with a non return valve, whereby fluid entering the first working chamber 24 of the cylinder 14 through the first port A will still be able to leave the first working chamber 24 of the cylinder 16 through port Bs when the piston 20 is in its fully extended position.
  • the non-return valve associated with the signal port Bs prevents oil flowing into the first working chamber 24 of the cylinder 16 through the signal port Bs.
  • the non-return valve may be required in instances where there is insufficient flow of oil from the pump to overcome the leakage through Bs and cause the piston 20 to retract.
  • This circulation of hydraulic fluid from the first port A of the cylinder through the signal port Bs which occurs at full extension of the piston rod (or any position along the length of the cylinder dependant upon the position of the signal port Bs) may be used to operate a switch mounted remotely from the coupler (e.g. a flow switch or a pressure switch), to provide a signal indicating that the extension of the cylinder has exceeded the preset value.
  • a switch mounted remotely from the coupler e.g. a flow switch or a pressure switch
  • This preset value may be slightly greater than the engagement position of the coupler rear hook with the maximum expected pin spread of the range of attachments. This signal can then be used to operate an indicator, which could be visual, audible or both, alerting the operator to incorrect locking of the attachment.
  • the hydraulic ram in accordance with the present invention has been described in relation to use in a hydraulic coupler for an excavator to detect and alert an operator to a situation wherein an attachment is incorrectly coupled to an arm of an excavator, it is envisaged that the hydraulic ram may be used in other applications wherein it is desirable to detect a fully out-stroked or fully extended state of the ram.
