Definitions
- the invention relates to a hand-operated lifting device with a pneumatic Lift drive, a lifting element connected to this, one at the end of the Lifting device arranged load lifting device and a pneumatic switch, the one connecting a compressed air source with a pressure chamber of the linear actuator Pressure line is integrated and the pressure chamber of the linear actuator in one Stable with the compressed air source and in another position with a ventilation device combines.
- Such a hand-controlled lifting device is known from EP 0 818 628-A.
- the invention is based, with little additional technical effort the task to create such a lifting device, which in the entire work area and regardless of the load to be moved at least approximately the same lifting and Lowering speeds reached.
- the throttle valves can be controlled in such a way that when they change axial length gives a corresponding change in the throttling effect.
- Such throttle valves can be designed so that axially extending housing protrudes a spring-loaded actuating pin at whose axial displacement changes the throttle cross-section inside the housing becomes.
- the two throttle valves or alternatively both throttle valves and both Combine check valves into a common structural unit.
- the two throttle valves can thus in a common outer housing be accommodated with their two axial ends against the inner surfaces two opposite walls of the outer casing, the mutual distance is changeable under elastic deformation, are present whose outer surfaces attack tensile or compressive forces from load-transmitting parts.
- the load-dependent elastic deformation of the outer housing thus acts the throttle valves so that almost the same stroke or lowering speed.
- a pneumatic lifting drive 1 in Form of a pneumatic cylinder is provided, in which below a piston 2 a pressure chamber 3 is arranged.
- a rope 5 is attached, which at its lower end a crane hook 6 as a load handling device wearing.
- the pressure chamber 3 is connected via a pressure line 7 from a compressed air source 8 Compressed air fed. Behind the compressed air source 8 is in the pressure line 7 pneumatic switch 9 turned on and in another fold behind this one Flow control device 10.
- the pneumatic switch 9 has three switch positions I, 0 and II.
- the switch In the Switch position I shown, the switch lets the compressed air from the compressed air source 8 flow freely to the flow control device. Will the Switch placed in switch position 0, this flow is prevented, as well as a return flow of air via the pressure line 7. In this switch position e.g. a raised load is held in the position reached.
- Switch position II In Switch position II is finally the compressed air supply from the compressed air source 8 completed, while the return flow of air from the pressure chamber 3 to the ventilation device 11 is open.
- the compressed air line is branched and two adjustable throttle valves D1 and D2 connected in parallel, which are each followed by a check valve R1 and R2 in series. Subsequently the compressed air line unites again and thus reaches the pressure chamber 3 of the linear actuator 1.
- the throttle valve D1 is by the acting on the crane hook 6 Force F adjusted in such a way that the throttle cross section reduces F at low load, with increasing load F, however, is increased. This ensures that the Lifting speed at least approximately regardless of the size of the load is equal to.
- the pneumatic one Switch 9 are brought into switch position II. This will make the Pressure line 7 connected to the venting device 11. The one when sinking of the piston 2 emerging from the pressure chamber 3 flows over the Pressure line 7 to the flow control device 10, where it is now the check valve R2 opens and then flows through the adjustable throttle valve D2.
- the throttle valve is dependent on the one acting on the crane hook 6 Force F is adjusted so that with increasing force F the throttle cross section reduced and thus prevents an abrupt drop in the load.
- a lifting device shown in Fig. 2 is on a pedestal 12 a parallelogram boom 13 and a bracket 14 pivotally mounted.
- On the console 14 is supported by a pneumatic lifting drive 1 with interposition a flow control direction 10 and engages with the piston rod 4 the parallelogram boom 13, whereby the latter is raised and lowered can be.
- a load arm 15 can be pivoted on the parallelogram boom 13 stored, which carries a crane hook 6 at its end.
- a pneumatic switch 9 is arranged, which is connected via a pressure line 7 on the one hand with a compressed air source 8 and on the other hand with the flow control device 10 is connected, which in turn via a pressure line 7 with the Pressure chamber of the linear actuator 1 is connected.
- the sequence of effects is here same as described above in Fig. 1.
- an adjustable throttle valve which consists of a Housing 16 is made, the interior 17 of a supply air opening 18 and Exhaust air opening 19 has. Between these openings there is an interior 17 Intermediate wall 20 is arranged, which has a throttle bore 21.
- a conical throttle needle 22 which with a longitudinally displaceable in Housing 16 mounted cylindrical guide 23 is connected, which in turn an actuating pin 24 protruding axially from the housing 16 having.
- a pressure plate 25 bears against the throttle needle from below is under the action of a spring 26 which the throttle needle in an upper End position presses.
- the variant of a throttle valve shown in FIG. 4 differs from that 3 only in that the throttle needle 22 in the opposite Direction is conical, so that in this case when pushing in Actuating pin 24 in the housing 16 of the throttle cross section is enlarged.
- a supply air hole opens into the interior 17 of the housing 16 18.
- an intermediate wall 20 is provided in the interior 17, each one Have throttle bore 21.
- One dips into each of these throttle bores tapered throttle needle 22, which are connected together and tapered in opposite directions are executed.
- the actuating pin is pressed down, then the Drassel cross section between the supply air opening 18 and the Exhaust air opening 19 increasingly reduced, while the throttle cross section between the supply air bore 18 and the exhaust air bore 27 is enlarged.
- This throttle valve thus replaces the two throttle valves shown in FIG. 1 D1 and D2.
- a cup-shaped outer housing 28 is shown, in which a reverse Pot-shaped hollow piston 29 is mounted for longitudinal displacement.
- the outer case 28 is closed at its open end by an inserted cover 30. through which a tie bolt 31 projects, which is connected to the Bottom of the hollow piston 29 is connected.
- a plate spring assembly 32 is arranged, which pushes the hollow piston 29 downwards in the outer housing 28.
- Both Throttle valves 33 and 34 are in one case a throttle valve 3 and in the other case by one according to FIG. 4. If this Component e.g. installed in the rope 5 according to FIG. 1, the rope forces engage on the one hand on the draw bolt 31 and on the other hand on the bottom of the outer housing 28 with increasing load of the hollow piston 29 against the action of the spring assembly 32 is moved upward, whereby the actuating pins 24 further from the Casings of the throttle valves 33 and 34 emerge and thus the inside Throttle cross sections can be changed.
- FIG. 7 A reverse variant is shown in FIG. 7.
- an outer case 35 provided, in which a hollow piston 36 is longitudinally displaceable and by a snap ring 37 is secured to come out down.
- Disc spring assembly 38 Between the The bottom of the outer housing 35 and the end face of the hollow piston 36 act Disc spring assembly 38, in the center of which a support part 39 is provided, against which the actuating pin 24 of a throttle valve 40 is supported, in which it 5 is a double-acting throttle valve.
- this component which is caused by the lifting device moving load is subjected to pressure, e.g. in an embodiment according to FIG. 2 are used.
- Fig. 8 finally shows a relatively simple variant, in which a double-acting Throttle valve 40 is inserted into a metal ring 41, which is at Exposure to tensile or compressive forces at points in the longitudinal direction of the Throttle valve are deformed such that the actuating pin 24 in one case in the throttle valve is pushed in, or further out of the other case can leak.
