Definitions

  • the invention is based on a hydraulic control arrangement, the features from the preamble of claim 1 having.
  • Such a hydraulic control arrangement is e.g. B. from DE 196 19 860 A1 known.
  • the inlet pipe is fed by a hydraulic pump, the pressure medium from the Tank sucks.
  • the control piston of the 2-way cartridge valve is on its Seated, the two inlet pipe sections are apart Cut. It becomes a standard 2-way cartridge valve used with directional function, the control piston two in the opening direction has acting opening areas, of which one is centrally located on the control piston, in its diameter corresponds to the seat diameter and the pressure in the second inlet line section is exposed.
  • the second opening area is an annular surface, the inside diameter of which is the seat diameter and the outside diameter of the guide diameter of the control piston and the pressure in the first Inlet line section is acted upon.
  • On the control piston is also an effective closing surface in the closing direction present to the pressure in a rear control room of the 2-way cartridge valve is exposed.
  • the two opening areas together are as large as the closing surface.
  • a pilot valve connects in a rest position, which it under the effect of a compression spring occupies the rear control room with the first inlet line section.
  • the position of the pilot valve is the 2-way cartridge valve Control piston usually in the closing direction of one Spring is acted upon by the pressure in the first inlet line section and the pressure in the second inlet line section, which is usually not greater than the pressure in the first Inlet line section is not to be opened.
  • the pilot valve can by energizing an electromagnet in a Switch position are brought in which it is the rear Control room on the control piston connects to the tank. Now he can prevailing in the first inlet line section and on the Ring surface of the control piston attacking pressure, the control piston from the seat against the generally weak closing spring lift off and open the 2-way cartridge valve.
  • An emergency stop can be implemented with the valve described.
  • the solenoid of the pilot valve In normal operation the solenoid of the pilot valve is excited and the 2-way cartridge valve open.
  • an occurring Emergency can e.g. an electrical switch operated that cuts off the electrical power supply, so that the solenoid of the pilot valve from the power supply is disconnected.
  • the pilot valve arrives by the compression spring in its rest position and connects the rear control chamber on the control piston with the first inlet line section, so that the 2-way cartridge valve closes and the inflow of pressure medium to the directional valve leak-free interrupts.
  • a hydraulic control arrangement is known from DE 43 24 177 A1 known according to the load-sensing principle, in which a isolating valve after triggering an emergency stop signal, two feed line sections separates from each other, shuts off the load signaling line and a load signaling connection on the controller of the variable pump connects with tank.
  • the isolating valve is again a slide valve.
  • the aim of the invention is to provide a hydraulic control arrangement to further develop with the features from the preamble of claim 1, that with simple means high security requirements are fulfilled.
  • a hydraulic system according to the invention is particularly advantageous Control arrangement if, according to claim 2, the directional control valve is hydraulic can be actuated and the control oil for actuating the second inlet line section is removed. Through the Pressure relief of the second inlet line section drops the control pressure decreases, so that therefore the return of the control spool the directional control valve in its rest position opposes. With an electro-hydraulic actuation of the Directional control valve does not switch off the electrical pilot control valves necessary.
  • a control block 10 contains two directional valve sections 11 and 12, each of which is a directional valve 13 with an inlet chamber 14, the pressure medium from a Hydraulic pump 18 can flow, a drain chamber 15, the is connected to a tank 19, and two consumer chambers 16 and 17, the consumer lines with a double-acting hydraulic consumers, not shown, e.g. are connected to a differential cylinder.
  • the control slide 27 of a directional valve 13 is from a central position, in which the inlet chamber, the outlet chamber and the two consumer chambers are cordoned off from each other, adjustable in opposite directions in working positions, in the between the inlet chamber 14 and the consumer chamber 16 or the consumer chamber 17 a measuring aperture 20 open and the other consumer chamber with the drain chamber 15 is connected.
  • the control room 23 has a load reporting chamber 25 of the directional control valve 13 and the control chamber 24 via the load holding valve connected to the inlet chamber 14.
  • the load reporting chamber 25 is in the central position of the control slide 27 to the tank relieved and in a side working position with the consumer chamber connected via the orifice 20 Pressure medium is supplied.
  • the control piston of the pressure compensator 22 is in the opening direction by a compression spring 26 and by the pressure prevailing in the control chamber 23 and in the closing direction acted upon by the pressure prevailing in the control chamber 24.
  • the two directional control valves 13 can each be actuated electro-hydraulically, why in each directional valve section 11 or 12 two Electromagnetically switched pilot valves 40 integrated are.
  • a leak oil channel 41 In the rest position of a valve 40 there is an associated one Control room on the control slide 27 of a directional control valve 13 a leak oil channel 41, which through the directional valve sections 11 and 12 passes through, relieved.
  • a control room becomes one also passed through the directional valve section 11 and 12 Control pressure line 42 connected.
  • the tax oil is via a pressure reducing valve 43 which is connected to the directional valve section 12 attached end plate 44 is included, one through and through the two directional valve sections 11 and 12 removed into the end plate 44 channel, the together with each led to the inputs of the pressure compensator 22 Branch lines a second inlet line section 60th is.
  • the pressure reducing valve 43 is e.g. at a control pressure set from 20 bar.
  • a safety block 51 is attached to the directional valve section 11, which is a 2-way cartridge valve 52, an associated pilot valve 53 and has a series of pressure medium channels.
  • the Control piston 54 of the 2-way cartridge valve 52 is a differential piston, which is guided axially with a piston section 55 and with a piston section 56 of smaller diameter axially seated on a seat 57 to an axial exit 58 to close.
  • the first Inlet line section 34 is connected.
  • From the axial exit 58 starts the second supply section 60, which is in the directional valve sections 11 and 12 as a continuous channel continues.
  • a pressure in the first inlet line section 34 acts on one Annular surface 64 and a pressure in the second inlet line section 60 on a circular surface 65, which is equal to the cross-sectional area of the small piston portion 56 is in the opening direction of the control piston 54.
  • the sum of the two areas 64 and 65 is equal to the size of the area 62.
  • the pilot valve 53 is a 4/2-way valve that operates a compression spring 69 assumes a rest position in which it the rear control chamber 61 on the control piston 54 with the connects the first inlet line section 34 and the second Inlet line section 60 via a channel 70 to tank 19 relieved.
  • the pilot valve 53 can be controlled by a Electromagnets 71 are brought into a switching position in which connects the rear control room 61 to the channel 70, so relieved to the tank and since it is a standard component acts, the first inlet line section 34 connects to the second inlet line section 60.
  • the electromagnet 71 In normal operation, the electromagnet 71 is excited so that the pilot valve 53 assumes the second switching position. Since in rear control room 61 there is tank pressure, the can of the ring surface 64, the pump pressure engaging the control piston 54 lift off the seat so that pressure medium with almost no pressure loss from the first inlet line section 34 into the second inlet line section 60 can reach.
  • the pressure compensator 33 regulates a pressure of e.g. 20 bar one that is equivalent to the force of a control piston of the Pressure compensator together with that in the load signaling line 31 Pressure acting on the compression spring in the closing direction 35 is.
  • the second inlet line section 60 becomes Tank relieves pressure so that during the closing process rapidly sinks at the opening area 65. This leads to one fast closing. Because the opening area 65 finally is completely relieved of pressure, engages the control piston 54 a large excess force in the closing direction, so that the control piston 54 sits firmly on its seat and the second inlet line section 60 leakage-free against the first Shuts off inlet line section 34. The discharge of the second inlet line section 60 also leaves the control pressure sink in the control pressure line 42 so that the directional control valves return to the middle position even if a pilot valve 40 remains switched.
  • Each directional valve section 11 now contains a 6-way throttle valve 80 generally known type with a circulation channel and with a load holding valve 81.
  • the directional control valves 80 are actuated electrohydraulically with the aid of pilot valves 40.
  • Control oil is housed in the end plate 44
  • Pressure reducing valve 43 one through the directional valve sections 11 extending inlet channel, the part of the second inlet line section 60 is removed and in a control pressure channel 42 delivered. So starting from the The central position of the directional control valves 80 is a control pressure at all can be built, the circulation channel is through a check valve 82 preloaded.
  • a constant pump 18 is used as the pressure medium source, which is secured by a pressure relief valve 83.
  • the Pump 18 sucks pressure medium from a tank 19 and emits it in a first inlet line section 34, which with the radial inlet 59 of the cartridge valve 52 is connected.
  • the second inlet line section 60 in turn starts from the axial one Output 58 of the cartridge valve 52.
  • the cartridge valve 52 In normal operation, the cartridge valve 52 is open, so that pressure medium delivered by the hydraulic pump 18 either completely is returned to the tank via the circulation channel or after actuating a directional valve in whole or in part reaches a hydraulic consumer. In an emergency by actuating an electrical switch the electromagnet 71 de-energized, so that the pilot valve 53 in its rest position arrives and the cartridge valve 52 closes.
