Definitions
- the invention relates to a hydraulic control arrangement for a mobile work machine, with at least one hydraulic Cylinder, with the help of which a working tool is movable, a directional control valve for controlling the pressure medium path between a Pressure chamber of the cylinder, a pressure medium source and a tank, one between the directional valve and the pressure chamber of the cylinder looped safety valve, which is used to adjust the Cylinder is openable, and with a pressure accumulator, which with the Pressure chamber of the cylinder is connectable.
- Hoists such as front loaders, are mounted on vehicles and used for lifting and transporting loads. she have hydraulic cylinders for lifting and usually also for pivoting the load on, by releasable, flexible Hoses from a host vehicle with pressurized Hydraulic fluid to be supplied. To prevent the load in the case of a hose break, which causes the pressure in the the load-holding cylinder leads, falls down, so become called load holding or safety valves used. These Valves block the connection between the cylinder and the cylinder Hose off as long as the operator does not move the hoist causes.
- the hydraulic cylinders of the hoists to connect with pressure accumulators serving as vibration dampers, at the lifting or lowering side of a cylinder or both Pages are provided (DE 197 34 658 A).
- pressure accumulators serving as vibration dampers, at the lifting or lowering side of a cylinder or both Pages are provided (DE 197 34 658 A).
- Such accumulator be at the vehicle - side junction of the Safety valves connected, since they are usually at Vehicle are located and through a hose with the safety valve are connected. Even when the safety valve is switched off To obtain a damping, the operator can Manually deactivate the safety valve. He then takes over Responsible for not performing a lifting operation.
- the safety valve depending on the To activate the speed of the vehicle. If with one certain speed is driven, it can be assumed be that the vehicle is not in the Hub but in the Transport mode is located. Then the accumulator is only in Driving operation effective.
- the object underlying the invention is seen therein a lifting device with a safety valve to the effect to improve that even when the safety valve is switched off a damping of the cylinder is possible, or that the Safety valve effective even with a damped cylinder remains.
- the accumulator can be directly or through a lockable, in the Usually remotely controllable valve with the pressure chamber of the cylinder get connected.
- the valve allows the accumulator switch off if an operator for more precise positioning of the Working tool to dispense with the effect of the pressure accumulator would like to.
- the accumulator is suitably mechanically rigid with the Cylinder and / or the safety valve coupled, so he moves with the cylinder and the safety valve and no breakage-prone hoses are required.
- the accumulator is preferably exclusively by means of mechanically rigid Conduit elements, such as pipes and the like, with the pressure chamber connected to the cylinder. This avoids the risk of Hose breaks that lead to a sudden drop in a load would.
- the leading to the accumulator line with connected to a second port of the pressure chamber of the cylinder be whose first port connected to the safety valve is.
- the accumulator is in the Integrated housing of the cylinder.

- On both sides of the lifting rocker 16 are each a cylinder 26 and 28 are arranged.
- the adjusting device 30 acts on the tool holder 32 to which the working tool 20th is directly connected, and essentially exposes itself a first and a second pivot arm 34, 36 together, the are hinged together, wherein in the hinge point 44th the cylinder 28 attacks.
- the tool holder 32 is in one Bearing 38 and the first pivot arm 34 in a bearing 40 at the Lifting rocker 16 pivotally mounted.
- the second pivot arm 36 is pivotally connected to the tool holder 32 in a bearing 46. 48 is a latch for locking the working tool 20th designated. In the upper portion of the tool holder 32 are a Hook 50 and a bolt 52 is provided, the working tool 20th bring into engagement with the hoist 10.
- FIG. 2 is a diagram of a hydraulic according to the invention Control arrangement for the working machine from FIG. 1 shown.
- a pump as a source of pressure medium 54 and a tank 56 for receiving relaxed Arranged pressure medium.
- the pump is over two from the operator of the cab of the tractor from actuatable directional valves 58, 60th connected to a coupling 62.
- On the releasable coupling 62 are the hydraulic connections of the hoist 10 connected.
- the single or double acting cylinders 26 are over the clutch 62 directly connected to the directional control valve 60, so that the Work tool 20 by pressing the directional control valve 60 in itself can be raised and lowered known manner.
- the other cylinders 28, however, are double-acting. Your Piston chamber 64 is urged to the working tool 20 after to pivot up. Analogously, its piston rod chamber 66 acted upon when the working tool 20 is pivoted downward shall be.
- the known safety valve block 68 is provided. Of the Safety valve block 68 is with two cylinder-side Provided connections, in each case a piston chamber 64 of the Cylinder 28 is connected.
- the safety valve block 68 contains for the two possible pressure fluid flow directions one safety valve 70, 72.
- the first safety valve 70 includes a check valve that opens when the pressure in the piston chamber 64 is smaller than the pressure at the associated Connection of the coupling 62. It opens automatically when the Operator the pressure in the piston chamber 64 by pressing the Directional valve 58 increased.
- the second safety valve 72 also includes a check valve similar to the one in the Safety valve 70 corresponds.
- the passage is thus automatically opened when the pressure in the Kolbenstangenkanuner 66 is greater than the pressure in the piston chamber 64, i.e. the cylinder 28 should contract, so that the Pressure fluid from the piston chamber 64 drain into the tank 56 can.
- the safety valves 70, 72 are opened as a result, when the operator via the directional control valve 58, a movement of Cylinder 28 causes and otherwise closed.
- the piston chamber of the right-hand cylinder 28 has two ports 76, 78 on.
