Definitions

  • the invention relates to a hydraulic drive according to the preamble of claim 1.
  • Such a drive is known for example from EP 0 451 724 B1.
  • the energy store consists of a plate spring assembly, the spring force of which acts on a piston which slides in a pressure cylinder and on the side of the pressure fluid chamber opposite the plate spring is provided.
  • the drive piston for the switch is located on the side next to the pressure cylinder, so that this arrangement requires a relatively large amount of space.
  • the hydraulic drive according to EP 0 158 054 B1 requires less space, in which the spring assembly acts with pull rods on a piston through which the drive piston rod engages.
  • the pressure cylinder, the drive piston rod, the drive cylinder chamber and the spring arrangement lie on one axis.
  • the object of the invention is to provide a hydraulic drive of the type mentioned and in which the space utilization is improved.
  • At least two axially extending bores are provided in the container arrangement, in each of which a pressure piston is slidably displaceable, on one end face of which the pressure piece rests and on the other end face of which the pressure fluid is present.
  • the container arrangement can comprise an annular container body which concentrically surrounds the working cylinder.
  • a flange edge can be provided on the working cylinder housing, which engages in a recess on the container body, so that the container body is pressed against the flange edge by the spring arrangement.
  • a pump for generating the pressure fluid can also be installed in the container body.
  • the container arrangement can have a number of container bodies which corresponds to the number of bores.
  • three container bodies are provided, which are attached to the working cylinder in an evenly distributed manner on the circumference thereof.
  • the working cylinder is hexagonal, wherein further components can be attached to the hexagonal surfaces between the container bodies.
  • the embodiment according to the invention offers the advantages of improved space utilization; the spring acts on the pressure piston without tie rods, so that no seals are therefore required in the area of the tie rods.
  • the energy is about one short distance to the working piston; the pressure pistons are practically directly on the working piston.
  • the cylinder body can consist of drawn material or forged material and the individual container bodies for the pressure pistons can be produced from easily machinable aluminum semi-finished products.
  • the hydraulic drive or hydraulic drive 10 has a cylinder body 11 for a working cylinder 12, in which a working piston 13 (also called a driving piston) is guided, to which a driving piston rod 14 connects, with which a high-voltage circuit breaker 15 can be actuated.
  • a working piston 13 also called a driving piston
  • a driving piston rod 14 connects, with which a high-voltage circuit breaker 15 can be actuated.
  • Damping elements 16 and 17 into the areas 18 and 19 and larger diameter than that of the drive piston rod 14 on both sides of the working piston 13 and brake the movement of the working piston 13 at the end of its movement damping.
  • a container body 20 with a larger diameter adjoins the cylinder body 11, in which three bores 21 are accommodated, of which only one bore can be seen. These bores 21 are located on a circle around the central axis MM of the hydraulic drive and are evenly distributed on this circle.
  • a support ring 22 which is fixedly connected to the cylinder housing 11.
  • the cylinder housing 11 is surrounded by a pressure ring 23 which is movably guided on the outer surface of the cylinder housing 11;
  • a spring arrangement 24 is provided between the pressure ring 23 and the support ring 22, which corresponds, for example, to the spring arrangement of the hydraulic device according to EP 0 451 724 B1 and can be designed as a plate spring assembly.
  • Pressure pistons 25 are received in the bores 21 and are moved in the arrow direction D by the spring arrangement 24.
  • a pressure fluid chamber 26 is provided, into which pressure fluid is supplied by a pump 27, which is driven by a motor 28, via a line 29 and the working cylinder 12 and a further line 30, 31, whereby the pressure piston is pressed out of the bore 21 in the opposite direction of the arrow D and thereby tensions the spring arrangement 24.
  • the lines 29, 30, 31 are introduced into the container body 20.
  • the line 30 continues to a P-connection of a reversing valve 32, which has a reversing slide 33, which is actuated by electromagnetic elements A and E in the opening or closing direction.
  • a line 34 which is connected to the T-connection of the valve 32, the pressurized fluid is fed through a filter 35 to a low-pressure tank 36, from where the pressurized fluid is again fed from the pump 27 to the working piston or the working cylinder 12.
  • the line 30 continues into a line 38 which is connected to the P connection of the valve 32; the Z-connection of the valve is connected via a line 39 to the space of the cylinder 12, which is on the side with the larger piston area.
  • the Fig. 1 shows the switch in the off position.
  • the pump 27 and the line 39 also deliver high pressure fluid to both sides of the working piston 13 from the spring arrangement and the pressure pistons with the switch valve 32 in the appropriate position; since the area of the working piston 13 to which the piston rod 14 is connected is smaller than the opposite area, the working piston 13 and the piston rod 14 are moved upward to close the switch 15. If the switch 15 is to be turned off, then a connection between the line 39 and 34 and the low-pressure tank 36 is created via the valve 32, so that the space on the side with the larger piston area is relieved; the pressure fluid in the space with the smaller piston side presses the working piston 13 in the off position.
  • the pressure fluid is provided both by the pump and by the energy storage device, which is formed by the spring arrangement 24 and the three pressure pistons 25 in the bores 21.
  • the pressurized fluid located in the rooms 26 then actuates the working piston 13 in the manner described.
  • Fig. 2 shows a detailed representation of a hydraulic drive in section, without showing the springs.
  • the cylinder body 11 contains the working cylinder 12 and the working or drive piston 13 is guided within the working cylinder 12.
  • the support ring 22 is held on the working cylinder 11 by means of a threaded bush 40 which has a step 41, against which a recess 42 bears against the support ring 22.
  • the threaded bush 40 is screwed onto an external thread 43 of the cylinder body 11.
  • the working cylinder 12 is closed by means of a closure piece 44 which has a blind hole 45 which is part of the working cylinder 12.
  • a plurality of transverse bores 46, 47 are provided in the closure piece 44, into which lines which run parallel to the working cylinder 12 open and which correspond to the lines 39 and 29 and have been given the reference numbers 48 and 49 here.
  • a container body Arranged around the cylinder body 11 at the opposite end is a container body, also called a container 50, which corresponds to the container housing or body 20 and has the bores 21, in each of which a pressure piston 25 is received.
  • a further pressure piece 23 is located between the support piece 22 and the container housing 50, and the spring arrangement 24 (not shown in FIG. 2) is located between them.
  • the end of the cylinder body 11 located at the top of the drawing has an edge 51 which engages in a recess 52 on the container housing 50; when all parts are put together and assembled, a pressure is exerted on the container housing 50 by the spring arrangement via the pressure piece 23, the pressure piston 25 and the pressure fluid, so that this rests against the flange edge 51 and thus the container housing 50 in its location is maintained.
  • the space 26 is connected via a bore 53 to a bore 54 in the cylinder body 11, which are aligned with one another and run radially to the cylinder body 11 and open into the working cylinder 12.
  • the line 48 is connected via a transverse bore 55 to a bore 56 which leads to the Z connection of the changeover valve 32.
  • the other bores that lead to the connections P and T are not shown in FIG. 2.
  • a cover 57 is placed, in which the filter 35 (not shown) is accommodated.
  • the working cylinder 12 is closed on the piston rod side by means of a further closure piece 58, through which the piston rod protrudes outwards and which engages in the cover 57 with the interposition of seals 59.
  • the hydraulic drive 70 has a cylinder body 71, in which a working cylinder 72 is introduced, in which a working piston 73 moves, which corresponds to the working piston 13 in its construction and its mode of operation.
  • the cylinder body 71 is closed at its end remote from the switch, that is to say at the bottom, by a bushing 74 which is held in place by a cover 75.
  • cylinder body 71 has a recess 76, as a result of which a region 77 with a reduced diameter is formed, which has an external thread 78, onto which a cylindrical collar 79 of a sleeve 80 is screwed.
  • the sleeve 80 has two mutually spaced grooves 81 and 82, in which a force transmission member 83 and 83 'engages.
  • the force transmission member 83 or 83 ' interacts with a pressure ring 84, 84' as follows: the force transmission member 83 has a radially inwardly projecting ledge 85 which engages in the groove or groove 81, and a conical surface 86 against which engages a conical surface 87 on the force introduction member 84.
  • the force transmission member 83 is divided into two ring halves that complement one another in the assembled state to form a ring.
  • the conical surfaces 87, 86 are arranged such that the force introduction member 84 (also called the pressure ring) partially concentrically surrounds the force transmission member 83.
  • the pressure ring 84 surrounds the sleeve 80 on its outer surface. The same effect is also achieved with the elements 83 ', 84'.
  • the cylinder body 71 On the cylinder body, specifically in the area of the switch-side end, the cylinder body 71 has a section 88 which forms a hexagonal profile on its outer circumference with six surfaces 89, 90, 91, 92, 93 and 94. In FIG. 3 the surface is 92 visible.
  • Container surfaces 95, 97 and 99 are fastened to surfaces 90, 92 and 94 with screw connections 96, 98 and 100, respectively.
  • the container body 95, 97 and 99 are constructed identically, so that it is sufficient to show the container body 95 with reference to FIG. 3.
  • the container body 95 is pot-shaped with a pot bottom 101 and a wall 102 which is cylindrical on the inside and, as can be seen in FIG. 4, is rectangular or square on the outside.
  • a bore 103 is made in the wall, in which a pressure piston 104 is slidably guided.
  • the open side of the container body 95 points towards the end remote from the switch and is tightly closed by means of a cover 105.
  • the cover 105 has a bore 106 through which a piston rod 107, which is integrally connected to the pressure piston 104, projects.
  • the cylinder body 71 is surrounded by a pressure body 108 which has a radial stop surface 109; there is a plate spring arrangement between the pressure ring 84 and the pressure body 108.
  • the pressure body 108 engages over the piston rod 107, so that when the pressure piston is pressed out of the container body 95, the latter clamps the spring arrangement via the pressure body 108.
  • the pressure body 108 can now be a ring; there is also the possibility that it has an annular section in the central region, on which arms are formed which overlap the piston rods 107 of all three container bodies.
  • the three container bodies 95, 97 and 99 are arranged in a star shape on the cylinder body 71 in the region 88 thereof; in between further hydraulic components can be formed on the respective surfaces 91, 93 and 95.
  • a changeover valve 110 is fastened to the side surface 91, a path detection 111 to the side surface 93 and a low-pressure drinking pump arrangement 112 to the surface 89 (this is only given as an example).
