Definitions

  • the invention relates to a load-independent release device for a load exerting force thereon, which is held in a CLOSED position of the release device and released in an OPEN position of the release device, with a housing and a release lever which is connected to a release pawl via a steering lever , wherein the release lever is rotatably mounted on a first housing axis, the release pawl on a second housing axis and the steering lever on a first steering lever axis on the release lever and on a second steering lever axis on the release pawl, as well as with a spring device acting at least on the release lever and a locking device which the release device is fixed in the CLOSED position.
  • a release device is used to separate a load from a device, for example a crane or a portal.
  • a release device that is independent of the load force separates the load from the device independently of the force that the load exerts on the release device prior to separation.
  • a heavy load blocks the release device because the parts that can be opened no longer move under the effect of the load force.
  • the release device can then only be opened by lifting the load force.
  • release devices that are independent of the load force the load force is not applied to the opening components, so that they can also open safely under the action of the load force on the release device.
  • release devices which are independent of the load force, are known, for example, for gliders (so-called “tow couplings"). Release devices that are independent of the load force are also of great advantage in the underwater area, because large loads often have to be lowered in the water under their downward force or have to be caught up in the water under their upward force.
  • a tow release for aircraft is described which is triggered independently of the force that a towed aircraft, usually a glider, exerts on the clutch.
  • a CLOSED position of the release device the aircraft is held in the air by means of a tow rope; in an "OPEN position" (open position) of the release device, the tow rope and thus the aircraft are released.
  • the known release device which is independent of the load force, comprises a housing on which a rotatable segment and a lever are arranged on a first housing axis. The segment and lever form a release lever. The first housing axis is fixed in place in the housing.
  • a release pawl is rotatably mounted on a second housing axis.
  • the second housing axis is also fixed in place in the housing.
  • the release lever and release pawl are articulated to one another by a steering lever.
  • the steering lever is rotatably mounted on a first steering lever axis on the release lever and on a second steering lever axis on the release pawl.
  • the steering lever is designed in the form of a straight bracket, the first and second steering lever axis are each arranged at one end of the steering lever. They are not fixed in the housing and move together with the steering lever.
  • the steering lever is only guided by the release lever and release latch, which under extreme conditions can lead to undefined and indissoluble positions of the steering lever in the housing.
  • the release lever (or the rotatable segment) and the steering lever together form a knee. In doing so, they are in their dead center position, so that they block each other and there is a self-retention. As a result of the knee, the force exerted by the load is diverted in the release device and no longer acts directly on the locking mechanism. For the triggering, a relatively small force independent of the load force must now be applied, which releases the knee.
  • a spring device is provided in the known release device, which acts on the release lever (or on the rotatable segment). The degree of kneeling or self-holding can be set by adjusting the spring force. This determines the release force.
  • the release pawl When releasing the knee joint or when pulling back the release lever and the straight steering lever, the release pawl is actuated at the same time. The load is then released by rotating it around the second housing axis.
  • the known release device has a locking device in the form of a manually operated eccentric lever, by means of which the release device is fixed in the CLOSED position (closed position).
  • the known triggering device is triggered either manually by actuating the trigger lever or automatically by force-induced shearing off of a trigger pin made of plastic, which locks the triggering device in the CLOSED position. To do this, the plastic pin blocks a spring-loaded counter pawl.
  • both trigger mechanisms are not suitable for reliably triggering the triggering device even from a distance and under the disruptive influence of external, irregular and sometimes very strong forces.
  • Force-independent release devices for underwater use are, for example, from the U.S. 3,504,407 A and the DE 10 2010 010 161 B4 known. However, these work without kneeling and direct the load forces around the release elements via massive structural components.
  • the task of the present invention is to further develop the generic load force-independent release device described at the beginning so that the release device can also be reliably operated from a distance and under the irregular influence of external forces, but without additional external forces Force application can be triggered, with undefined positions of the steering lever in the housing must be avoided. All the advantages of a release device that is independent of the load force should be retained. The solution to this problem can be found in the main claim. Advantageous further developments of the invention are shown in the subclaims and explained in more detail below in connection with the invention.
  • the steering lever is angular and in the CLOSED position of the release device rests on a first contact surface in the housing and in the OPEN position of the release device on a second contact surface in the housing, with the two steering lever axes on the first contact surface of the steering lever are positioned immediately before a self-holding dead center position to the first housing axis and on the second contact surface of the steering lever outside the dead center position, and that the spring device is designed as a tension spring which is arranged between the release lever and the release pawl and in the CLOSED position the release device exerts a force on the release lever in the direction of the OPEN position of the release device.
  • the steering lever is angled and is guided between two contact surfaces, the steering lever in the CLOSED position being in contact with the first contact surface and in the OPEN position in contact with the second contact surface.
  • the steering lever which does not occupy a fixed axis in the housing, but only articulated with the release lever and the release pawl is connected, thus occupies only firmly defined positions in the release device. This increases the reliability of the trip.
  • the defined position is also supported by the angularity of the steering lever, which at least in the CLOSED position advantageously rests on a correspondingly angled contact surface. Vertical shifts are reliably avoided.
  • the angularity of the steering lever is advantageous in order to bring the two steering lever axes on the steering lever in the CLOSED position of the release device with the first housing axis into a position immediately before their dead center position. Due to the angularity, the two steering lever axes can be positioned above and below the first housing axis.
  • the steering lever is deliberately brought very close to the dead center position so that it always tries to get out of this position in the direction of the OPEN position. Nevertheless, by positioning the steering lever in relation to the housing in an approximately dead-center position, the load forces acting on it do not act on the steering lever and block it, if necessary, but are introduced around it into the housing.
  • the release movement of the steering lever is supported by the tension spring provided between the release lever and the release pawl, which is arranged at a slight angle.
  • the premature or unintentional triggering is prevented by the locking device, by means of which the triggering device is reliably fixed in the CLOSED position.
  • the release device opens automatically and without any further external force input, since the energy stored in the tension spring folds over the steering lever, which is just before dead center and has a tendency to fold over, at an accelerated rate. Due to the tendency of the steering lever to want to open automatically, in connection with the tension spring, any obstructions of the release device, such as rust, dirt, deposits (especially in underwater use) and friction, can be safely overcome.
  • the release device according to the invention provides a simple but particularly reliable release that is independent of the load force and that reliably releases even heavy loads under adverse environmental conditions and does not block in undefined positions.
  • the two contact surfaces for the steering lever are preferably and advantageously formed by a closed contour in the housing.
  • This also gives the contact surfaces a precisely defined position and stability.
  • a contour can be produced relatively easily in a housing wall by milling.
  • the release lever is A-shaped (trapezoidal).
  • the tension spring can then be attached to the preferably flattened tip of the release lever without bending the release lever.
  • the locking device can then act on the release lever immediately next to it.
  • the release pawl can have a hook in its lower area, into which, for example, a rope for the load can be hung.
  • the rope can be secured on the hook, for example, via the housing as a counter bearing.
  • a counter pawl is provided which is rotatably mounted on a third housing axis and forms a closed eye with the release pawl and the housing in the CLOSED position of the release pawl and the housing in which the load can be held.
  • the suspended load then does not have to slip off a hook. Rather, the holding surface is completely dissolved when opening, so that the release of the load is reliably guaranteed.
  • a heavy-duty version with a load capacity of up to 3 t can preferably and advantageously be provided.
  • the housing has a receptacle for a load rope. It is therefore preferred and advantageous if the housing has an elongated hole open on one side to form the eyelet. The rope can then be inserted into this elongated hole and is there without a large lateral play safely guided.
  • the mating pawl can assume a defined position in the CLOSED position of the release device, it is preferred and advantageous if the mating pawl has a nose which is mounted on an end stop in the housing in the CLOSED position of the release device. Furthermore, the release pawl and the counter pawl can preferably and advantageously have shoulders which are attached to one another in the CLOSED position of the release device. All of these measures are used to reliably secure the load rope in the CLOSED position of the release device.
  • the CLOSED position is held exclusively by the action of the locking device.
  • the locking device comprises an electromagnetic trigger with an axially displaceable trigger pin, by means of which the trigger lever is fixed in the closed position of the triggering device in the housing, the axially displaceable trigger pin being arranged orthogonally to the trigger lever.
  • An electromagnetic trigger solenoid actuator
  • the trigger pin is held in the CLOSED position by the armature of the electromagnet and locked there by a spring. The trigger pin engages the trigger lever through a hole.
  • the electromagnet When triggered, the electromagnet is actuated electrically and causes the trigger pin to be withdrawn into the interior of the trigger, so that the trigger lever is released.
  • the tension spring especially in the form of a spiral spring, i.e. spiral tension spring
  • the release lever Under the acting spring force of the tension spring (especially in the form of a spiral spring, i.e. spiral tension spring) the release lever is pulled down and takes the steering lever with it.
  • the electromagnetic release or the axially displaceable release pin is preferably and advantageously arranged orthogonally to the release lever. This prevents accidental external forces acting on the release device from inadvertently actuating the release. Unintentional forces in the direction of the axially displaceable trigger pin can still occur because the trigger pin is quite light and is held in position by a small spring.
  • the locking device comprises an additional safety device through which the release lever is in the CLOSED position of the release device is fixed in the housing.
  • the additional fuse can preferably and advantageously be designed as a spring pin. This is a transport lock that must be removed manually. Remote triggering is not provided.
  • a tab for manual positioning of the release lever in the OPEN position of the release device can be arranged on the release lever. This improves the manual handling of the release device. No tools are required to move the system into the CLOSED position. Furthermore, for easy handling of the force-independent release device according to the invention, it is preferred and advantageous if a suspension is arranged at the upper end. This can be, for example, a rod that is connected to a portal or a shackle that is connected to a rope.
  • the release device claimed with the invention is particularly resistant to accidental load surges from the outside. Such effects can occur if the release device is used in the underwater area. Here it can be exposed to strong waves or currents or ship movements.
  • the claimed release device can in particular be used on a research ship and serve to deploy a measuring apparatus there. Autonomous underwater vehicles (lander) with a weight of over 2 t can also be deployed. It is imperative to ensure that there is no triggering takes place above the water level in order to prevent damage to the measuring apparatus when it hits the water surface.
  • the release may only take place in the water body (the measuring apparatus then sinks further) or only after the measuring apparatus has been placed on the bottom of the water. It is therefore preferred and advantageous, particularly in the case of operations at sea, if a seawater-proof material design is provided for the release device which is independent of the load force. In particular, stainless steels and plastics are used here.
  • the invention relates to the locking device.
  • the electromagnetic release must be protected. On the one hand, it can be integrated into a pressure-resistant housing. However, it is preferred and advantageous to design the electromagnetic release to be pressure-neutral. For this purpose, it is filled into a transparent plastic cylinder that can be closed with two lids and completely filled with a pressure fluid, mostly pressure oil. For volume compensation, a flexible pressure compensation element that is connected to the ambient pressure (i.e. also to the ambient medium water) is inserted into the plastic cylinder.
  • This can preferably and advantageously be a pressure-resistant tubular bag made of PVC, such as is used in the medical sector for collecting liquids.
  • the tubular bag has an integrated supply hose through which the seawater can penetrate into its interior and can be easily adapted to any volume. Further details on the use of such bags and their advantages can be found in the older German registrations 102017119115.1 (pressure-neutral battery) and 102017119158.5 (pressure-neutral electric motor). Further details on the invention and its embodiments can be found in the embodiments described below.
  • a load force-independent release device 01 is shown for an application in the underwater area.
  • the materials used are therefore seawater-proof.
  • the release device 01 is in the CLOSED position, in which a load, for example an OFOS (Ocean Floor Observation System) in a setting frame, is held, for example on a crane on a research ship.
  • the OFOS and the lowering frame weigh several hundred kilograms, which in the hanging state act on the release device 01 as a whole, but not on the immediate release area. Rather, the force is directed past it through the release device 01 .
  • the triggering device 01 can be triggered independently of the load force acting by applying only a small triggering force.
  • the release device 01 comprises a housing 02, which in the exemplary embodiment shown consists of two structured steel sheets 03, 04 (cf. Fig. 3 ) is screwed together. This has the advantage that the further, in particular movable, components can be arranged between the two steel sheets 03, 04 and are thus protected from external influences.
  • the release device 01 further comprises a release lever 05, which is rotatably mounted on a stationary first housing axis 06. In the embodiment shown, the release lever 05 is A-shaped, with a flattened upper edge 07 having.
  • the release device 01 comprises a release pawl 08 which is rotatably mounted on a stationary second housing axis 09.
  • the housing 02 consists essentially of the two steel sheets 03, 04 arranged parallel to one another.
  • the release lever 05 and the release pawl 08 work between the two steel sheets 03, 04. So that there is no obstruction with the steering lever 10 , it consists of two parallel ones Parts of which one part is guided in the steel sheet 03 and the other part in the steel sheet 04 in the contour 21 (see below).
  • the steering lever 10 is the steering lever 10 shown consisting of two parts. A one-piece design is also easily possible.
  • the steering lever 10 is rotatably connected to the release lever 05 via a movable first steering lever axis 11 and to the release pawl 08 via a movable second steering lever axis 12.
  • the two steering lever axes 11, 12 and the first housing axis 06 are arranged to one another immediately before their dead center position 41 (dashed line in FIG Fig. 1 Showing that the second steering lever shaft 12 is slightly deviated from the linear connection between the housing axis 06 and the first steering arm axis 11).
  • This arrangement results in an extensive knee, consisting of the release lever 05 and steering lever 10, which ensures that a load force occurring on the release pawl 08 is not transmitted to the release lever 05.
  • the steering lever 10 is not fixed in the dead center, but has a tendency to want to move in the direction of the OPEN position.
  • This is supported by a spring device 13 in the form of a tension spring 14, which is arranged between the upper edge 07 of the release lever 05 and the release pawl 08 .
  • the tension spring 14 is positioned slightly obliquely, ie an upper stop point 15 of the tension spring 14 is slightly offset vertically from a lower stop point 16.
  • the tension spring 14 (in the embodiment shown is a simple, standardized, commercially available coil spring) is in the CLOSED position and has a tendency to pulling the release lever 05 downwards.
  • a locking device 17 with an axially displaceable trigger pin 18 which engages from behind through an opening in the trigger lever 05 (cf. Fig. 3 ) and fix it in the CLOSED position. If the fixation is canceled, the tension spring 14 pulls the steering lever 11 directly into the OPEN position, which leads to an immediate opening of the release pawl 08 .
  • the steering lever 10 is angled. In the embodiment shown, it is bent in its center at an obtuse angle of approximately 120 °. In the CLOSED position, it rests against a first contact surface 19 in the housing 02 . Its position is thus precisely defined. The first contact surface 19 is also formed at an obtuse angle. In the OPEN position, on the other hand, the steering lever 10 is mounted on a second contact surface 20 in the housing 02 (cf. Fig. 2 ). This position is also precisely defined. The second contact surface 20 is also formed at an obtuse angle.
  • the two contact surfaces 19, 20 are formed by a contour 21 in the housing 02 .
  • This is in both steel sheets 03, 04 (compare Fig. 3 ) and has the closed shape of a boomerang.
  • the first steering lever axis 11 rests on the first contact surface 19 in the upper region of the contour 21 .
  • the second steering lever axis 12 rests on the second contact surface 20 in the lower area of the contour 21 (cf. Fig. 2 ).

  • the housing 02 or the two steel sheets 03, 04 has an elongated hole 25 that is open on one side.
  • the nose 26 For a defined position of the counter pawl 22 in the CLOSED position, it has a nose 26 which presses against an end stop 27 in the housing 02.
  • the end stop 27 can be designed in the form of a small shaft 28 between the two steel sheets 03, 04 be.
  • the release pawl 08 and the counter pawl 22 also have shoulders 29 , with which they rest securely against one another.
  • FIG. 1 the locking device 17 can only be seen in the area of the trigger pin 18 , further details are shown in FIG Fig. 3 with insert. It is shown here that the locking device 17 is arranged on the rear side of the release device 01 , specifically orthogonally to it (the release pin 18 is arranged orthogonally to the release lever 05 ). This right-angled arrangement to each other reliably prevents false tripping due to undesired forces, such as can occur in particular when immersing in the surface of the water.
  • the locking device 17 comprises an electromagnetic trigger 30 (for example solenoid actuator Intertec®ITS-LS-4035-D-12VDC) in which an actuator (armature with or only trigger pin 18) within a magnetic coil linearly, ie in the direction of the axis is moved back and forth.
